Description

The present invention relates to a monitored person monitoring support system and a monitored person monitoring support method for supporting monitoring of a monitored person.

In recent years, with the advent of a super-aging society, techniques for supplementing work in the nursing industry, nursing care industry, etc. have been researched and developed.

A fall detection device disclosed in Patent Document 1 includes a human body image including a partial image representing a human body to be detected, position coordinate information representing a coordinate position of the partial image, and the The height of the human body is reduced by comparing the height information included in the size information with the height information included in previously acquired size information based on the size information representing the size of the human body. an appearance feature amount extraction unit for extracting an appearance feature amount based on the appearance of the human body image when the height is reduced; and the appearance feature amount. an appearance detection unit that identifies whether or not the human body is in a collapsed state based on the result of referring to a first appearance dictionary based on the above; calculating the movement distance of the partial image included in the human body image based on the position coordinate information acquired in the above, comparing the movement distance with a threshold value, and based on the comparison result, representing the human body a movement distance detection unit that detects whether or not the movement distance of the partial image is less than the threshold, and detects that the human body included in the human body image has fallen when the movement distance is short.

The wheelchair with a seat sensor disclosed in Patent Document 2 is a wheelchair equipped with position detection means for detecting the position of the wheelchair and communication means for transmitting the detected position of the wheelchair to a management center. Equipped with a seating sensor that detects that the

The call system disclosed in Patent Document 3 includes a floor detection sensor that detects an object existing on the floor near the bed used by the monitored person, and an object on the floor near the bed used by the monitored person. a human body detection sensor that detects an object near the bed so that the monitored person is detected when the monitored person stands up and the monitored person is not detected when the monitored person falls from the bed; A notification device for notifying that a person has left the bed, and notification reason information indicating the reason for calling by distinguishing between the movement of the monitored person and the fall of the monitored person from the bed are stored. a timer section for measuring time; and when the floor detection sensor detects an object, the notification device and the timer section are operated until the time measured by the timer section reaches a predetermined time. When the human body detection sensor detects an object, the storage device stores notification reason information indicating that the monitored person has left the bed and moved, and the time measured by the timer unit reaches a predetermined time. and a control unit that causes the storage device to store notification reason information indicating that the monitored person has fallen off the bed if the human body detection sensor does not detect the object even after the object is reached. . The floor detection sensor 1 is composed of an infrared sensor or the like, and detects the feet of the monitored person when the monitored person using the bed tries to leave the bed, and detects the feet of the monitored person when the monitored person falls off the bed. It is installed at a position where the monitored person's body can be detected (paragraph [0015] of Patent Document 3, etc.). The human body detection sensor 2 is composed of an infrared sensor or the like, and when the monitored person using the bed stands up on the floor near the bed where the floor detection sensor 1 is installed, the body of the monitored person is detected. (e.g., the head of the monitored person) can be detected and the body of the monitored person cannot be detected if the monitored person using the bed falls out of bed. (paragraph [0018] of Patent Document 3, etc.). Therefore, in the call system disclosed in Patent Document 3, the installation height of the infrared sensor as the floor detection sensor is different from the installation height of the infrared sensor as the human body detection sensor, so that the monitored person can get out of bed. Distinguishing between moving away and the monitored person falling out of bed.

By the way, for example, when a monitored person such as a person being cared for or a person being cared for falls, for example, and a monitor such as a nurse or a caregiver receives a report of the fall from the system, the monitor normally: A countermeasure such as going to the monitored person for whom the notification is issued is executed. However, if the alarm is a false alarm that is issued because the system determines that the person to be monitored is not falling over, the supervisor's response is useless and labor is lost. turn into. On the other hand, if the system fails to detect the state of falling, etc., and does not issue an alarm, the situation, such as falling, will be left unattended, and may develop into a more serious situation. have a nature. Therefore, it is desired that errors such as false alarms and missing alarms are further suppressed and that alarms are issued more appropriately.

In the case of detecting a fall or the like based on an image like the fall detection device disclosed in Patent Document 1, for example, there is a state in which the person falls on his buttocks and a state in which he sits on a chair and leans back or leans forward. are difficult to distinguish because they look similar on the image. Further, for example, a state in which a person is sitting on a chair or a wheelchair and a state in which the person has slipped down from the chair or wheelchair look similar on the image, making it difficult to distinguish between them. For this reason, there is a possibility that an erroneous alarm may occur. In particular, in order to prevent misreporting, it is necessary to issue a report in all such cases that are difficult to determine, resulting in an increase in false reports.

In addition, due to the positional relationship between the position of the bed and the arrangement position of the sensor, when the supervisor works on the monitored person on the bed, the positional relationship in which the monitored person, the supervisor, and the bed overlap with each other as viewed from the sensor. Therefore, it may be difficult to determine from the image whether the monitored person has been moved from the bed to the wheelchair or is still sleeping. There is also a risk of erroneous determination.

The wheelchair with a seat sensor disclosed in Patent Document 2 only reports the current position of the wheelchair and whether or not the user is seated (paragraph [0012] of Patent Document 2, etc.). Therefore, in the wheelchair with a seating sensor disclosed in Patent Document 2, if the wheelchair is not seated, it is not seated because the person has moved from the wheelchair to another place, or the wheelchair is not seated because the user has fallen from the wheelchair. Therefore, it is impossible to detect a fall or the like. For this reason, if the seating sensor determines that a fall has occurred when the person is not seated and issues an alarm, erroneous alarms occur frequently.

The call system disclosed in Patent Document 3 uses infrared sensors at different positions to determine whether the monitored person has fallen. are all determined to be falls, and there is a risk that false alarms will occur frequently.

The private branch exchange (circuit switch) CX is connected to the network NW, controls extension calls such as outgoing calls, incoming calls, and conversations between the mobile terminal devices TAa, performs extension calls between the mobile terminal devices TAa, and , for example, is connected to an outside line telephone TL such as a fixed telephone or a mobile telephone via a public telephone network PN such as a fixed telephone network or a mobile telephone network, and originating, receiving and calling between the outside telephone TL and the mobile terminal device TAa. etc., to carry out an outside line call between the outside line telephone TL and the portable terminal device TAa. The private branch exchange CX is, for example, a digital exchange, an IP-PBX (Internet Protocol Private Branch Exchange), or the like.

The monitored person monitoring support system MSa is arranged at an appropriate place according to the monitored person Ob. The monitored person (person to be watched over) Ob is, for example, a person who needs nursing care due to illness or injury, a person who needs nursing care due to a decline in physical ability, a solitary person living alone, or the like. In particular, from the viewpoint of enabling early detection and early countermeasures, the monitored person Ob should be a person who needs to be found when a predetermined inconvenient event, such as an abnormal condition, occurs to him or her. preferable. Therefore, the monitored person monitoring support system MSa is preferably installed in buildings such as hospitals, welfare facilities for the elderly, and dwelling units according to the type of the monitored person Ob. In the example shown in FIG. 1, the monitored person monitoring support system MSa is installed in a building of a nursing care facility having a plurality of rooms RM in which a plurality of monitored persons Ob reside and a plurality of rooms such as a nurse station. .

The sensor device SUa has a communication function or the like to communicate with other devices SVa, SPa, and TAa via the network NW, detects a predetermined action of the person to be monitored Ob, and sends the detection result together with an image to the management server device SVa. It is the sending device. Then, in the present embodiment, the sensor device SUa detects that the monitored person Ob is seated, and transmits the detection result to the management server device SVa. different processing methods based on For example, as shown in FIG. 2, such a sensor device SUa includes an imaging unit 11, a seating detection unit 12, a sensor-side control processing unit (SU control processing unit) 13a, and a sensor-side communication interface unit (SU communication IF unit) 14 and a sensor-side storage unit (SU storage unit) 15 .

The imaging unit 11 is arranged so as to be able to monitor a space (located space, in the example shown in FIG. 1, a living room (room) RM at the installation location) where the monitored person Ob, who is a monitoring target to be monitored, is scheduled to reside. , the location space is imaged from above as an imaging target, a bird's-eye view image (image data) of the imaging target is generated, and the image of the imaging target (target image) is output to the SU control processing unit 13a. Preferably, since it is highly probable that the entire monitored person Ob to be monitored can be imaged, the imaging unit 11 detects the position of the head of the monitored person Ob in the bedding (for example, a bed) on which the monitored person Ob lies. It is arranged so that the imaging target can be imaged from directly above the planned and preset head position (usually, the position where the pillow is arranged). The sensor unit SU acquires an image of the monitored person Ob from above the monitored person Ob, preferably from right above the expected head position, using the imaging unit 11 .

In this embodiment, the imaging optical system of the imaging unit 11 is preferably a wide-angle optical system (a so-called wide-angle lens (including a fisheye lens)) capable of imaging the entire living room RM in which it is installed. . Alternatively, the imaging unit 11 may be a thermography camera that generates a heat distribution image of an object to be imaged.

The seating detection unit 12 is connected to the SU control processing unit 13a, and is arranged in a device such as a chair, a wheelchair, and a toilet facility, on which the monitored person Ob is scheduled (assumed) to sit. It is a device that detects The seating detection unit 12 outputs the seating detection result to the SU control processing unit 13a. For example, the seating detection unit 12 determines whether or not the monitored person Ob is seated at predetermined time intervals (sampling intervals). You may output to the management server apparatus SVa as a seating detection result. Further, for example, the seating detection unit 12 determines whether or not the monitored person Ob is seated at predetermined time intervals (sampling intervals), and only when it detects that the monitored person Ob is seated. "Yes" may be output to the management server device SVa as the seating detection result. In this case, the SU control processing unit 13a can recognize that there is no seating because the presence of seating is not input. The seating detection unit 12 may be connected to the SU control processing unit 13a by wire, or may be connected to the SU control processing unit 13a by short-range wireless communication such as the Bluetooth (registered trademark) standard.

Such a seating detection unit 12 includes a contact-type seating sensor such as a pressure sensor or a vibration sensor. The pressure sensor is arranged, for example, on a seat surface of a chair, a wheelchair, a toilet, etc., so as to detect pressure (increase in pressure) due to seating of the monitored person Ob. The vibration sensor is arranged, for example, on a seat surface of a chair, a wheelchair, a toilet, or the like, so as to detect vibration caused by sitting of the person to be monitored Ob.

Further, for example, the seating detection unit 12 includes a non-contact seating sensor such as a heat sensor. The heat sensor is arranged to detect heat (infrared radiation) radiated from the monitored person Ob, for example, within a placement area such as a chair and toilet facilities.

The SU communication IF unit 14 is a communication circuit that is connected to the SU control processing unit 13a and performs communication under the control of the SU control processing unit 13a. The SU communication IF unit 14 generates a communication signal containing data to be transferred input from the SU control processing unit 13a according to the communication protocol used in the network NW of this monitored person monitoring support system MSa. A communication signal is sent to the other device SVa, SPa, TAa via the network NW. The SU communication IF unit 14 receives communication signals from other devices SVa, SPa, and TAa via the network NW, extracts data from the received communication signals, and can process the extracted data by the SU control processing unit 13a. format data and output to the SU control processing unit 13a. The SU communication IF unit 14 includes, for example, a communication interface circuit conforming to the IEEE802.11 standard or the like.

The SU storage unit 15 is a circuit that is connected to the SU control processing unit 13a and stores various predetermined programs and various predetermined data under the control of the SU control processing unit 13a. The various predetermined programs include, for example, an SU control program that controls each unit of the sensor device SUa according to the function of each unit, and an SU monitoring processing program that executes predetermined information processing regarding monitoring of the monitored person Ob. and other control processing programs. The SU monitoring processing program includes a behavior detection processing program for detecting a predetermined behavior of the person to be monitored Ob, and a detection result of the behavior detection processing program is processed by different processing methods based on the seating detection result of the seating detection unit 12. A detection result processing program for processing is included. The various types of predetermined data include a sensor identifier (sensor ID), which is an identifier for specifying and identifying the sensor device SUa, and the communication address of the management server device SVa. It contains data etc. necessary for executing the program. The SU storage unit 15 includes, for example, a ROM (Read Only Memory) that is a non-volatile storage element, an EEPROM (Electrically Erasable Programmable Read Only Memory) that is a rewritable non-volatile storage element, and the like. The SU storage unit 15 includes a RAM (Random Access Memory) or the like that serves as a so-called working memory of the SU control processing unit 13a that stores data generated during execution of the predetermined program.

The SU control processing unit 13a controls the respective units 11, 12, 14, and 15 of the sensor unit SUa according to the functions of the respective units 11, 12, 14, and 15, and controls a preset predetermined number related to the monitored person Ob. It is a circuit for detecting an action and transmitting the detection result together with an image to the management server device SVa. Then, in the present embodiment, the SU control processing unit 13a detects that the monitored person Ob is seated, and transmits the detection result to the management server device SVa. Different processing methods are used based on the detection results. The SU control processing unit 13a is composed of, for example, a CPU (Central Processing Unit) and its peripheral circuits. The SU control processing unit 13a functionally includes a sensor-side control unit (SU control unit) 131, an action detection processing unit 132, and a detection result processing unit 133a by executing the control processing program.

The SU control unit 131 controls the units 11, 12, 14, and 15 of the sensor device SUa according to the functions of the respective units 11, 12, 14, and 15, and governs the overall control of the sensor device SUa.

The behavior detection processing unit 132 detects a predetermined behavior of the monitored person Ob. More specifically, in the present embodiment, the predetermined actions are, for example, the monitored person Ob getting out of bed, the monitored person Ob falling from the bedding, and the monitored person Ob falling down. There are three behaviors of falling. The behavior detection processing unit 132 detects, for example, getting out of bed, falling, and falling of the monitored person Ob based on the target image captured by the imaging unit 11 .

More specifically, first, the location area of the bedding BD, the first threshold Th1 for determining the presence or absence of leaving the bed, and the second threshold Th2 for determining the presence or absence of falling or overturning are set to 1 of the various predetermined data. are stored in advance in the SU storage unit 15 as one. The setting screen shown in FIG. 3 is displayed on the terminal devices SPa and TAa, for example, the fixed terminal device SPa, for the location area of the bedding BD. coordinates on the target image) are input and stored in the sensor device SUa from the fixed terminal device SPa via the management server device SVa. On the setting screen, the target image generated by the imaging unit 11 is displayed on the fixed terminal device SPa via the management server device SVa. In addition, when the seating detection unit 12 is a non-contact seating sensor, the four vertex positions (coordinates on the target image) in the arrangement area such as the chair and the toilet equipment can be displayed from the setting screen. is input and stored in the sensor unit SUa from the fixed terminal unit SPa via the management server unit SVa. In the present embodiment, the presence or absence of leaving the bed is determined by the current state of the person to be monitored Ob and, as shown in FIG. ) is determined based on the magnitude of Hout. Therefore, the first threshold value Th1 is a value for distinguishing between the size of the protruding region before leaving the bed and the size of the protruding region after leaving the bed, and is appropriately set in advance from a plurality of samples. As shown in FIGS. 5B and 5D, the presence or absence of a fall or a fall is determined based on changes over time in the position and size of the monitored person Ob's head region HD. For this reason, the second threshold Th2 is a size for distinguishing between the size of the head region HD in the standing posture and the size of the head region HD in the sitting posture (or lying posture). value, which is arbitrarily set from a plurality of samples in advance.

Then, the action detection processing unit 132 extracts a moving body area as a human area (human area) HA of the monitored person Ob from the target image by, for example, a background subtraction method or a frame subtraction method. The action detection processing unit 132 extracts the human area (moving body area) HA from the extracted human area (moving body area) HA by, for example, a circular or elliptical Hough transform, for example, by pattern matching using a head model prepared in advance, or by, for example, the head A neural network trained for detection extracts the head region HD of the monitored person Ob. In the detection of getting out of bed, the behavior detection processing unit 132 detects that the current state of the monitored person Ob is before getting out of bed and the ratio of the protruding area HAout to the person area HA exceeds the first threshold value Th1 ((HAout/ When HA)>Th1)), it is determined that the patient has left the bed, and the above-mentioned leaving the bed is detected. In the fall detection, the behavior detection processing unit 132 detects when the position of the extracted head region HD (for example, the center position of the head region) changes over time from within the location area of the bedding BD to outside the location area of the bedding BD. When the size of the extracted head region HD is equal to or smaller than the second threshold value Th2, the fall is determined and detected. In the fall detection, the behavior detection processing unit 132 determines that the position of the extracted head region HD is within the living room RM excluding the area where the bedding BD is located, and that the size of the extracted head region HD is the second size. If it is equal to or less than the threshold Th2, it is determined that the fall has occurred, and the fall is detected.

The detection result processing unit 133 a processes the detection result of the behavior detection processing unit 132 by different processing methods based on the seating detection result of the seating detection unit 12 . More specifically, in the present embodiment, the detection result processing unit 133a uses the first processing method to display the detection result on the terminal devices SPa and TAa when the seating detection result indicates that the monitored person Ob is not seated. Then, when the result of the seating detection is that the monitored person Ob is seated, the detection result is processed by a second processing method that does not display the detection result on the terminal devices SPa and TAa. More specifically, the second processing method is a processing method that does not transmit the detection result to the management server device SVa. That is, in the first processing method, as described above, when the action detection processing unit 132 detects the predetermined action, if the seating detection result is not that the monitored person Ob is seated, the detection result processing unit 133a , the SU communication IF unit 14 manages a communication signal (first action detection notification communication signal) for notifying (notifying) of the detection, containing information representing the content of the detected predetermined action of the monitored person Ob. It is transmitted to the server device SVa. The first behavior detection notification communication signal includes, for example, the sensor ID of the device itself, information indicating the content of the detected predetermined behavior of the monitored person Ob (in this embodiment, any one of getting out of bed, falling, and falling). ), and the target image used for detecting the predetermined action. In the second processing method, as described above, even if the behavior detection processing unit 132 detects the predetermined behavior, if the seating detection result is that the monitored person Ob is seated, the detection result processing unit 133a , does not transmit the first action detection notification communication signal. The process of transmitting the first action detection notification communication signal may be executed by the action detection processing unit 132. In this case, if the result of the seating detection is that the monitored person Ob is not seated, the action detection processing unit 132 to transmit the first action detection notification communication signal, and on the other hand, when the result of the seating detection is that the monitored person Ob is seated, the action detection processing unit 132 transmits the first action detection notification communication signal. Disable transmission processing.

The SV communication IF unit 21 is configured with, for example, a communication interface circuit conforming to the IEEE802.11 standard or the like.

The SV storage unit 23 is a circuit that is connected to the SV control processing unit 22 and stores various predetermined programs and various predetermined data under the control of the SV control processing unit 22 . The various predetermined programs include, for example, an SV control program that controls each section of the management server apparatus SVa according to the function of each section, and an SV monitoring process that executes predetermined information processing regarding monitoring of the monitored person Ob. A control processing program such as a program is included. The various predetermined data include a server identifier (server ID), which is an identifier for specifying and identifying the management server device SVa, the monitoring information of the monitored person Ob, and the like. It contains the data necessary for executing each program. The SV storage unit 23 is composed of, for example, ROM, EEPROM, RAM and their peripheral circuits.

The SV control processing section 22 controls each section of the management server device SVa according to the function of each section, and when receiving a notification of the predetermined action from the sensor device SUa, manages monitoring information relating to monitoring of the monitored person Ob. and notifies (re-notify, re-notify, or transmit) the predetermined behavior to predetermined terminal devices SPa and TAa, provides the client with data according to the client's request, and manages the monitored person monitoring system MSa as a whole. This circuit is for The SV control processing unit 22 is configured including, for example, a CPU and its peripheral circuits. The SV control processing unit 22 functionally includes a server-side control unit (SV control unit) 221 and a server-side monitoring processing unit (SV monitoring processing unit) 222 by executing the control processing program.

The SV control section 221 controls the respective sections 21 and 23 of the management server apparatus SVa according to the functions of the respective sections 21 and 23, and governs the overall control of the management server apparatus SVa.

When the SV monitoring processing unit 222 receives a notification of the predetermined action from the sensor device SUa, the SV monitoring processing unit 222 manages monitoring information regarding monitoring of the monitored person Ob, and notifies the predetermined action to the predetermined terminal devices SPa and TAa. be.

More specifically, when the SV monitoring processing unit 222 receives the first behavior detection notification communication signal from the sensor device SUa, the SV monitoring processing unit 222 monitors the monitored person Ob contained in the received first behavior detection notification communication signal. is stored (recorded) in the SV storage unit 23. Then, the SV monitoring processing unit 222, in order to report (re-notify, re-notify, transmit) the detection result notified by the first action detection notification communication signal, In addition, the SV communication IF unit 21 transmits a communication signal (second action detection notification communication signal) containing information representing the content of a predetermined action of the monitored person Ob to the predetermined terminal devices SPa and TAa. The second action detection notification communication signal includes, for example, the sensor ID contained in the received first action detection notification communication signal, and information representing the content of the predetermined action of the monitored person Ob (in this embodiment, out of bed, fall, and fall), and the target image is stored. The second action detection notification communication signal may be transmitted to the terminal devices SPa and TAa by broadcast communication, for example. Further, for example, the second behavior detection notification communication signal may be transmitted only to the terminal devices SPa and TAa associated with the sensor device SUa that transmitted the first behavior detection notification communication signal. In this case, the SV storage unit 23 stores in advance the correspondence between the sensor device SUa (sensor ID) and the terminal devices SPa and TAa (terminal IDs) in one-to-one or one-to-many correspondence. . The terminal ID (terminal identifier) is an identifier for specifying the terminal devices SPa and TAa and identifying the terminal devices SPa and TAa.

6, the management server device SVa is further connected to the SV control processing unit 22 as necessary, and a server side input unit (SV input unit ) 24, a server-side output unit (SV output unit) 25 for outputting various commands and data input by the SV input unit 24 and monitoring information related to monitoring of the monitored person Ob, and data exchange with external devices. A server-side interface unit (SVIF unit) 26 or the like for inputting and outputting data may be provided.

Such a management server device SVa can be configured by, for example, a computer with a communication function.

This management server device SVa corresponds to an example of a central processing unit.

The fixed terminal device SPa has a communication function to communicate with other devices SUa, SVa, and TA via the network NW, a display function to display predetermined information, and an input function to input predetermined instructions and data. By inputting predetermined instructions and data given to the sensor device SUa, the management server device SVa, and the portable terminal device TAa, and displaying the monitoring information obtained by the sensor device SUa, the monitored person monitoring support system MSa can be operated. It is a device that functions as a user interface (UI) for Such a fixed terminal device SPa can be configured by, for example, a computer with a communication function.

FIG. 10 is a flow chart showing the operation in the bed leaving detection process shown in FIG. FIG. 11 is a flow chart showing the operation in processing the detection result shown in FIG. 7 in the first embodiment. FIG. 12 is a sequence diagram showing the operation of the monitored person monitoring system according to the first embodiment. FIG. 13 is a diagram showing an example of a monitoring information display screen displayed on a mobile terminal device in the monitored person monitoring support system in the first embodiment.

In the monitored person monitoring support system MSa configured as described above, each of the devices SUa, SVa, SPa, and TAa initializes each necessary unit when the power is turned on, and starts its operation. In the sensor device SUa, the SU control processing unit 13a is functionally configured with an SU control unit 131, an action detection processing unit 132, and a detection result processing unit 133a by executing the control processing program. In the management server device SVa, the SV control processing unit 22 is functionally configured with an SV control unit 221 and an SV monitoring processing unit 222 by executing the control processing program. Then, the sensor unit SUa detects a predetermined motion of the monitored person Ob by operating as follows for each frame or every several frames.

In FIG. 7, the sensor unit SUa acquires an image (image data) of one frame from the imaging unit 11 as the target image by the SU control unit 131 of the SU control processing unit 13a (S1).

Next, the sensor unit SUa extracts the human area HA in order to detect a predetermined action of the monitored person Ob based on the target image by the action detection processing unit 132 of the SU control processing unit 13a. In the present embodiment, the person area HA is sufficient for detecting getting out of bed, but the head area HD is used for detecting a fall or a fall. A head area HD is extracted from the extracted person area HA (S2).

Next, the action detection processing unit 132 of the sensor unit SUa executes action detection processing for detecting a predetermined action of the monitored person Ob based on the person area HA and the head area HD extracted in the process S2. (S3).

More specifically, in this behavior detection processing S3, the behavior detection processing unit 132 executes a fall detection processing S31 for detecting a fall or a fall in FIG. Processing S32 is executed.

More specifically, in the fall detection processing S31, the action detection processing unit 132 in FIG. 9 first determines whether or not a fall or fall condition is satisfied (S311). More specifically, first, the action detection processing unit 132 performs the processing S2 when the position of the head region HD extracted in the processing S2 changes over time from within the location region of the bedding BD to outside the location region of the bedding BD. If the size of the head region HD extracted in 1 is equal to or smaller than the second threshold value Th2, it is determined that the user has fallen (Yes), the fall is detected (S312), and the process S31 ends. Then, the behavior detection processing unit 132 determines that the position of the head region HD extracted in the processing S2 is within the living room RM excluding the location region of the bedding BD, and the size of the head region HD extracted in the processing S2 is If it is equal to or less than the second threshold Th2, it is determined that the fall has occurred (Yes), the fall is detected (S312), and the process S31 ends. On the other hand, when excluding these, the action detection processing unit 132 determines that neither a fall nor a tumble has occurred (No), and terminates this processing S31.

More specifically, in the detection processing S32 of getting out of bed, the behavior detection processing unit 132 first determines whether or not the monitored person Ob is in a state before getting out of bed in FIG. 10 (S321). The state of the monitored person Ob is stored in the SV storage unit 23 as a state variable or the like. As a result of this determination, if the monitored person Ob is in a state before leaving the bed (Yes), the action detection processing unit 132 sequentially executes each of processing S322, processing S323, and processing S324. exit. On the other hand, if the result of the determination is that the monitored person Ob is not in the state before getting out of bed (No), the behavior detection processing unit 132 terminates the process S32.

In the process S322, the behavior detection processing unit 132 determines whether or not the conditions for getting out of bed are satisfied. More specifically, first, when the ratio of the protruding area HAout to the person area HA exceeds the first threshold Th1 ((HAout/HA)>Th1)), the action detection processing unit 132 determines that the person has left the bed (Yes ), the state of the monitored person Ob is updated (changed) after leaving the bed (S324, the state variable←“after leaving the bed”), and the process S32 ends. On the other hand, when excluding this, the behavior detection processing unit 132 determines that the person is not leaving the bed (No), and terminates the process S32. Note that when it is detected that the monitored person Ob is getting up from the lying state or when it is detected that the monitored person Ob is in bed, the state of the monitored person Ob is updated (changed) before leaving the bed (the above-mentioned state variable ← “Before leaving bed”).

When the action detection process S3 is executed in this manner, the sensor device SUa causes the detection result processing section 133a of the SU control processing section 13a to convert the detection result of the action detection process S3 into the seating detection result of the seating detection section 12. (S4), and the present process ends.

More specifically, in FIG. 11, the detection result processing unit 133a first acquires the seating detection result of the seating detection unit 12 (S41).

Next, the detection result processing unit 133a determines whether or not the monitored person Ob is seated (S42). As a result of this determination, if the seating detection result obtained in the process S41 indicates that the monitored person Ob is seated (Yes), the process S43 is executed and the process S4 ends. On the other hand, if the result of the determination is that the monitored person Ob is not seated (No), the process S44 and the process S45 are sequentially executed, and the main process S4 is terminated. finish.

In the processing S43, the detection result processing unit 133a cancels and deletes the detection result detected in the processing S3 in order to process the detection result by the second processing method that does not display the detection result on the terminal devices SPa and TAa. Therefore, the detection result processing unit 133a does not transmit the detection result detected in the process S3 to the management server device SVa. When the sensor unit SUa detects the predetermined behavior, if the seating detection unit 12 detects that the monitored person Ob is seated, the monitored person Ob is seated, so there is no risk of leaving the bed, falling, falling, or the like. , the detection result of the predetermined behavior is highly likely to be an erroneous detection, and the detection result can be corrected by the seating detection result of the seating detection unit 12 . In particular, when the predetermined behavior is detected based on an image, the seating detection result is considered to have higher detection reliability than the image detection result. can be properly corrected.

In the process S44, the detection result processing unit 133a confirms the detection result detected in the process S3 (determines (certifies) the final detection result). Then, in the processing S45, the detection result processing unit 133a transmits the detection result confirmed in the processing S44 to the management server device SVa in order to process the detection result by the first processing method for displaying the detection result on the terminal devices SPa and TAa. Send. That is, in the present embodiment, the detection result processing unit 133a transmits the first behavior detection notification communication signal to the management server device SVa through the SU communication IF unit 14. FIG.

With the sensor unit SUa operating as described above, in the monitored person monitoring support system MSa, for example, as shown in FIG. When no seating is detected (C1), the sensor device SUa transmits a first behavior detection notification communication signal to the management server device SVa (C2). When receiving the first behavior detection notification communication signal, the management server device SVa stores the monitoring information contained in the received first behavior detection notification communication signal (C3), and stores the received first behavior detection notification communication signal. A second action detection notification communication signal based on the signal is transmitted to predetermined terminal devices SPa and TAa (C4). Upon receiving the second behavior detection notification communication signal, the terminal devices SPa and TAa display the monitoring information contained in the received second behavior detection notification communication signal on the monitoring information display screen (C5). This monitoring information display screen is a screen for displaying monitoring information, and an example thereof is shown in FIG. In the example shown in FIG. 13, the monitoring information display screen 51 is displayed on the mobile terminal device TAa. The monitor information display screen 51 displays the room name of the room RM in which the predetermined action was detected, the name of the detected predetermined action, and the target image when the predetermined action was detected. In order to display the room name of the living room RM displayed on the monitoring information display screen 51, the mobile terminal device TAa is provided with the sensor ID and the room of the living room RM in which the sensor device SUa having the sensor ID is arranged. Correspondence with names is stored in advance. Based on this correspondence relationship, the mobile terminal device TAa searches for the room name of the room RM corresponding to the sensor ID contained in the second behavior detection notification communication signal, and displays the room name based on this search result on the monitoring information display screen 51. do. Then, the portable terminal device TAa displays the name of the predetermined action contained in the second action detection notification communication signal and the target image on the monitoring information display screen 51 . Accordingly, the supervisor (user) who handles the portable terminal device TAa refers to the monitoring information display screen 51 to notify the monitored person Ob in the room RM of the room name of the predetermined behavior detected. It can be recognized and its state can be recognized from the target image.

On the other hand, in the monitored person monitoring support system MSa, when the sensor unit SUa operates as described above, the action detection processing unit 132 detects a predetermined action and the seating detection unit 12 detects that a person is seated. (C6) The sensor device SUa cancels and deletes the detection of the predetermined behavior, thereby not transmitting the first behavior detection notification communication signal to the management server device SVa. Therefore, the management server device SVa does not transmit the second behavior detection notification communication signal based on the first behavior detection notification communication signal to the predetermined terminal devices SPa and TAa. The monitor information display screen 51 based on the signal is also not displayed. As a result, the monitored person monitoring support system MSa can issue a report more appropriately.

As described above, the monitored person monitoring support system MSa and the monitored person monitoring support method implemented therein according to the first embodiment process the detection result based on the seating detection result. Results can be more reliable and therefore can be reported better.

The monitored person monitoring support system MSa and the monitored person monitoring support method described above display the detection result on the terminal devices SPa and TAa when the seating detection result indicates that the monitored person Ob is not seated. Since the detection result is not displayed on the terminal devices SPa and TAa when the monitored person Ob is seated, the reliability of the detection result can be enhanced, and therefore, the alarm can be issued more appropriately.

When the monitored person Ob gets out of bed depending on the nursing level or care level, for example, for the purpose of assistance such as excretion, washing, and dressing, or for the purpose of preventing the person from falling, the monitor receives the notification, Go to the person Ob. When the monitored person Ob falls or overturns, the monitor goes to the monitored person Ob upon receiving the notification for the purpose of rescuing the monitored person Ob. In the monitored person monitoring support system MSa and the monitored person monitoring support method, the predetermined action includes at least one of "getting out of bed", "falling" and "falling", so that the warning is more appropriately issued. As a result, wasted effort due to false alarms can be reduced, and the burden on the monitor can be effectively reduced.

In the above-described embodiment, the detection result processing unit 133a is provided in the sensor device SUa, but may be provided in the management server device SVa instead of the sensor device SUa, or may be provided in the terminal devices SPa and TAa. It's okay to be

FIG. 14 is a sequence diagram showing the operation of the monitored person monitoring system in the first modification of the first embodiment. FIG. 15 is a sequence diagram showing the operation of the monitored person monitoring system in the second modification of the first embodiment.

When the management server device SVa includes a detection result processing unit, first, the detection result processing unit 133a is omitted from the sensor device SUa, and instead of the detection result processing unit 133a, the behavior detection processing unit 132 transmits the first detection result notification communication signal. It is transmitted to the management server device SVa. In this case, the first detection result notification communication signal includes the sensor ID of the device itself, information indicating the content of a predetermined action of the detected monitored person Ob (in the present embodiment, information indicating the content of the predetermined action of the monitored person Ob (in this embodiment, out of bed, falling, and falling). any), and the target image used to detect the predetermined action, and further, the seating detection result (in this embodiment, either sitting or not seated) is stored. be. The management server device SVa not only functionally equips the SV control processing unit 22 with the SV control unit 221 and the SV monitoring processing unit 222, but also functionally equips the SV control processing unit 22 with a detection result processing unit. The detection result processing unit in the management server device SVa receives the detection result contained in the first detection result notification communication signal received from the sensor device SUa as information representing the content of the predetermined behavior of the monitored person Ob. Different processing methods are used based on the seating detection result of the seating detection unit 12 contained in the first detection result notification communication signal. More specifically, the detection result processing unit in the management server device SVa displays the detection result on the terminal devices SPa and TAa when the seating detection result indicates that the monitored person Ob is not seated (when the monitored person Ob is not seated). If the seating detection result indicates that the monitored person Ob is seated (if the monitored person Ob is seated), the detection result is not displayed on the terminal devices SPa and TAa. do. More specifically, the second processing method is a processing method that does not transmit the detection result to the terminal devices SPa and TAa. That is, in the above description, since the SV monitoring processing unit 222 transmits the second behavior detection notification communication signal based on the received first behavior detection notification communication signal to the predetermined terminal devices SPa and TAa, the detection in the management server device SVa The result processing unit permits the SV monitoring processing unit 222 to transmit the second behavior detection notification communication signal when the result of the seating detection is that the monitored person Ob is not seated (when the monitored person Ob is not seated), and the seated person Ob is not seated. When the detection result indicates that the monitored person Ob is seated (when the monitored person Ob is seated), the SV monitoring processing unit 222 is prohibited from transmitting the second action detection notification communication signal.

In the monitored person monitoring support system MSa according to the first modification, when the behavior detection processing unit 132 detects a predetermined behavior and the seating detection unit 12 detects no seating, the first detection result notification is sent. The above-described processes C1 to C5 shown in FIG. 12 are executed, except that the communication signal further includes the seating detection result.

On the other hand, in FIG. 14, when a predetermined action is detected by the action detection processing unit 132 and no seating is detected by the seating detection unit 12 (C11), the sensor unit SUa further indicates that there is seating as the seating detection result. The received first behavior detection notification communication signal is transmitted to the management server device SVa (C12). When the management server device SVa receives the first behavior detection notification communication signal, the management server device SVa stores the monitoring information contained in the received first behavior detection notification communication signal (C13), and the seating detection result indicates that the person is seated. Therefore, the process of transmitting the second behavior detection notification communication signal to the predetermined terminal devices SPa and TAa based on the received first behavior detection notification communication signal is prohibited. Therefore, the management server device SVa does not transmit the second behavior detection notification communication signal based on the first behavior detection notification communication signal to the predetermined terminal devices SPa and TAa, and the terminal devices SPa and TAa transmit the second behavior detection notification communication signal. The monitoring information display screen 51 based on the above is not displayed. As a result, the monitored person monitoring support system MSa can issue a report more appropriately. In addition, since the management server device SVa stores the monitoring information contained in the first action detection notification communication signal received in the process C13, the monitor (user) can check the storage contents of the management server device SVa. , the fact that the false alarm has been stopped by the management server device SVa can be verified.

Note that, in the above description, the detection result processing unit in the management server device SVa causes the SV monitoring processing unit 222 to transmit the second action detection notification communication signal according to the seating detection result indicating no seating or seating. Although permitted or prohibited, the detection result processing unit in the management server device SVa executes the transmission processing of the second behavior detection notification communication signal instead of the SV monitoring processing unit 222 like the detection result processing unit 133a described above. You can In this case, like the detection result processing unit 133a described above, the detection result processing unit in the management server device SVa performs transmission processing of the second action detection notification communication signal in accordance with the seating detection result indicating no seating or seating. to run or not to run.

When the terminal devices SPa and TAa include the detection result processing unit, first, the detection result processing unit 133a is omitted from the sensor device SUa, and the detection result Instead of the processing unit 133a, the action detection processing unit 132 further transmits a first detection result notification communication signal containing the seating detection result to the management server device SVa. In the management server device SVa, the SV monitoring processing unit 222 receives the sensor ID contained in the received first action detection notification communication signal, information representing the content of the predetermined action of the monitored person Ob (in this embodiment, one of leaving the bed, falling, and falling), and not only containing the target image in the second detection result notification communication signal, but also the seating detection contained in the received first action detection notification communication signal. It also contains the result (either seated or not seated in this embodiment). Each of the terminal devices SPa and TAa includes a detection result processing unit. The detection result processing units in the terminal devices SPa and TAa transmit the detection result contained in the second detection result notification communication signal received from the management server device SVa as information representing the content of the predetermined behavior of the monitored person Ob, Different processing methods are used based on the seating detection result of the seating detection unit 12 contained in the received second detection result notification communication signal. More specifically, the detection result processing units in the terminal devices SPa and TAa send the detection results to the terminal devices SPa and TAa when the seating detection result indicates that the monitored person Ob is not seated (when the monitored person Ob is not seated). a first processing method for displaying, and a second processing method for not displaying the detection result on the terminal devices SPa and TAa when the seating detection result indicates that the monitored person Ob is seated (when the monitored person Ob is seated) process. More specifically, the second processing method is a processing method that does not display the detection result. That is, the detection result processing unit in the terminal devices SPa and TAa displays the detection result on the monitoring information display screen 51, for example, when the seating detection result indicates that the monitored person Ob is not seated (when the monitored person Ob is not seated). If the result of the detection of seating is that the person to be monitored Ob is seated (if the person to be monitored Ob is seated), the detection result is not displayed.

In the monitored person monitoring support system MSa according to the second modification, when the behavior detection processing unit 132 detects a predetermined behavior and the seating detection unit 12 detects no seating, the first and second Each of the above-described processes C1 to C5 shown in FIG. 12 is executed for each of the detection result notification communication signals, except that the seating detection result is further accommodated.

On the other hand, in FIG. 15, when a predetermined action is detected by the action detection processing unit 132 and no seating is detected by the seating detection unit 12 (C21), the sensor unit SUa further indicates that there is a sitting as the seating detection result. The received first behavior detection notification communication signal is transmitted to the management server device SVa (C22). When the management server device SVa receives the first behavior detection notification communication signal, the management server device SVa stores the monitoring information contained in the received first behavior detection notification communication signal (C23). The received second behavior detection notification communication signal is transmitted to the predetermined terminal devices SPa and TAa (C24). When the terminal devices SPa and TAa receive the second behavior detection notification communication signal, the terminal devices SPa and TAa display the monitoring information display screen 51 based on the received second behavior detection notification communication signal because the seating detection result indicates that the user is seated. do not do. As a result, the monitored person monitoring support system MSa can issue a report more appropriately. In addition, since the management server device SVa stores the monitoring information contained in the first action detection notification communication signal received in the process C23, the supervisor (user) can check the storage contents of the management server device SVa. , terminal devices SPa and TAa can verify the fact that false alarms have been stopped.

Next, another embodiment will be described.

(Second embodiment)
FIG. 16 is a flow chart showing the operation in processing the detection result shown in FIG. 7 in the second embodiment. FIG. 17 is a flow chart showing the operation of the mobile terminal device regarding the display of the monitoring information display screen in the second embodiment. FIG. 18 is a diagram showing another example of the monitoring information display screen displayed on the mobile terminal device in the monitored person monitoring support system in the second embodiment.

The monitored person monitoring support system MSa according to the first embodiment processes the detection results by different processing methods, such as whether or not to display them on the terminal device based on the seating detection results. The person monitoring support system processes the detection results by different processing methods for displaying on the terminal device in different display modes based on the seating detection results.

For example, as shown in FIG. 1, the monitored person monitoring support system MSb in the second embodiment includes one or a plurality of sensor devices SUb (SUb-1 to SUb-4), a management server device SVa, It comprises a fixed terminal device SPb, one or more mobile terminal devices TAb (TAb-1, TAb-2), and a private branch exchange CX, which are communicably connected via a network NW. The management server device SVa in the monitored person monitoring support system MSb of the second embodiment is the same as the management server device SVa in the monitored person monitoring support system MSa of the first embodiment, so the description thereof will be omitted.

For example, as shown in FIG. 2, the sensor device SUb includes an imaging unit 11, a seating detection unit 12, an SU control processing unit 13b, an SU communication IF unit 14, and an SU storage unit 15. FIG. The imaging unit 11, the seating detection unit 12, the SU communication IF unit 14, and the SU storage unit 15 in the sensor device SUb of the second embodiment correspond to the imaging unit 11 and the seating detection unit 12 in the sensor device SUa of the first embodiment, respectively. , the SU communication IF unit 14 and the SU storage unit 15, the description thereof will be omitted.

The SU control processing unit 13b controls each unit of the sensor device SUb according to the function of each unit, detects a predetermined action related to the monitored person Ob, and outputs the detection result together with an image to the management server device. Circuit for sending to SVa. In this embodiment, the SU control processing unit 13b detects the seating of the monitored person Ob, and transmits the detection result to the management server device SVa. Different processing methods are used based on the detection results. The SU control processing unit 13b functionally includes an SU control unit 131, an action detection processing unit 132, and a detection result processing unit 133b by executing a control processing program. The SU control unit 131 and the action detection processing unit 132 in the SU control processing unit 13b of the second embodiment are similar to the SU control unit 131 and the action detection processing unit 132 in the SU control processing unit 13a of the first embodiment, respectively. Therefore, the description is omitted.

The detection result processing unit 133b processes the detection result of the action detection processing unit 132 by a different processing method based on the seating detection result of the seating detection unit 12. FIG. More specifically, in this embodiment, the detection result processing unit 133b displays the detection result on the terminal devices SPb and TAb in a predetermined first display mode when the seating detection result indicates that the monitored person Ob is not seated. The terminal devices SPb and TAb display the detection result in a predetermined second display mode different from the first display mode when the seating detection result indicates that the monitored person Ob is seated. is processed by the fourth processing method. The first and second display modes are display modes that represent the degree of reliability of the detection result, and the second display mode is a display mode that indicates that the degree of reliability is lower than that of the first display mode. be. More specifically, first, in the present embodiment, the predetermined behavior includes not only getting out of bed, falling down, and falling, but also suspected that the monitored person Ob has left the bedding. is suspected to have left the bedding), suspected fall is suspected that the monitored person Ob fell from the bedding (suspected fall is suspected that the monitored person Ob may have fallen from the bedding), monitored person Ob collapsed Suspected fall (suspected fall that the monitored person Ob may have fallen down) is included. The suspicion of getting out of bed is a detection result with a lower reliability than the above-mentioned getting out of bed. The fall suspicion is a detection result with lower reliability than the fall. The fall suspicion is a detection result with lower reliability than the fall. In the third processing method, the detection result processing unit 133b confirms the detection result as it is and displays the detection result as it is in the first display mode when the seating detection result is not that the monitored person Ob is seated. It is displayed on the terminal devices SPb and TAb. That is, in the third processing method, when the behavior detection processing unit 132 detects the predetermined behavior and the seating detection result is not that the monitored person Ob is seated, the detection result processing unit 133b performs the first behavior detection. A notification communication signal is transmitted to the management server device SVa by the SU communication IF unit 14 . In this embodiment, in the first display mode, the detected predetermined action of the monitored person Ob is displayed, for example, on the monitoring information display screen 51 shown in FIG. 13 described above. In the fourth processing method, the detection result processing unit 133b changes the detection result to a suspicion detection result and displays the suspicion detection result when the seating detection result is that the monitored person Ob is seated. 2 display modes are displayed on the terminal devices SPb and TAb. In the present embodiment, when the detection result is leaving the bed, the detection result processing unit 133b changes the bed leaving to suspicion of leaving the bed when the seating detection result is that the monitored person Ob is seated. When the detection result is a fall, the detection result processing unit 133b changes the fall to suspected fall when the seating detection result is that the monitored person Ob is seated. When the detection result is a fall, the detection result processing unit 133b changes the fall to a suspected fall when the seating detection result is that the monitored person Ob is seated. That is, in the fourth processing method, when the behavior detection processing unit 132 detects the predetermined behavior and the seating detection result is that the monitored person Ob is seated, the detection result processing unit 133b performs the first behavior detection. A notification communication signal is transmitted to the management server device SVa by the SU communication IF unit 14 . In the second display mode, the detected predetermined behavior of the monitored person Ob is displayed, for example, on monitoring information display screens 52 and 53 shown in FIG. 18, which will be described later. A display mode different from the first display mode indicates that the detection result is relatively unreliable. The first behavior detection notification communication signal includes, for example, the sensor ID of the device itself, information indicating the content of a predetermined behavior of the monitored person Ob detected (in this embodiment, getting out of bed, falling, falling, suspected getting out of bed, falling suspicion and fall suspicion), and the target image used for detecting the predetermined behavior. In the third processing method, the first action detection notification communication signal contains one of getting out of bed, falling, and falling. In the fourth processing method, the first action detection notification communication signal , suspected falls and suspected falls are accommodated.

Each of the fixed terminal device SPb and the mobile terminal device TAb sends the second action detection notification communication signal received from the management server device SVa a detection result of suspicion (in this embodiment, any one of suspicion of getting out of bed, suspicion of falling, and suspicion of falling). or) is accommodated, the detection result of suspicion is displayed in the second display mode for displaying the detection result of suspicion, fixed in the monitored person monitoring support system MSa of the first embodiment Since it is the same as the terminal device SPa and the mobile terminal device TAa, the description thereof will be omitted.

In such a monitored person monitoring support system MSb according to the second embodiment, the sensor device SUb, similarly to the sensor device SUa according to the first embodiment, is provided with the sensor device shown in FIG. 7 for each frame or every few frames. , the above-described image acquisition processing S1, the above-described extraction processing S2 of the person region, etc., the above-described predetermined action detection processing S3, and the detection result processing S5 performed as described later are sequentially executed. By doing so, a predetermined action of the monitored person Ob is detected.

In the detection result processing S5 in the second embodiment, in FIG. 16, the detection result processing unit 133b first acquires the seating detection result of the seating detection unit 12 (S51).

Next, the detection result processing unit 133b determines whether or not the monitored person Ob is seated (S52). As a result of this determination, if the seating detection result obtained in the process S51 indicates that the monitored person Ob is seated (Yes), the process S53 is executed, then the process S55 is executed, and the process S5 is terminated. do. On the other hand, if the result of the determination is that the monitored person Ob is not seated (No), the process S54 is executed, then the process S55 is executed, and then the main process S5 is executed. exit.

In the processing S53, in order to process the detection result by the fourth processing method of displaying the detection result on the terminal devices SPb and TAb in a second display mode that indicates that the reliability of the detection result is relatively low, The detection result processing unit 133b changes the detection result detected in process S3 to a suspicious detection result. That is, when the detection result of the processing S3 is getting out of bed, falling down, and falling, the detection result processing unit 133b changes the detection result to suspicion of getting out of bed, suspicion of falling, and suspicion of falling. When the sensor unit SUb detects the predetermined behavior, if the seating detection unit 12 detects that the monitored person Ob is seated, the monitored person Ob is seated, and therefore, there is no possibility of leaving the bed, falling, falling, or the like. , the detection result of the predetermined behavior is less reliable than when the seating detection unit 12 does not detect the seating of the monitored person Ob, and the detection result can be corrected by the seating detection result of the seating detection unit 12. . In particular, when the predetermined behavior is detected based on an image, the seating detection result is considered to have higher detection reliability than the image detection result. can be properly corrected.

In the process S54, the detection result processing unit 133b causes the terminal devices SPb and TAb to display the detection result in the first display mode that indicates that the detection result is a detection result with relatively high reliability. In order to process by the method, the detection result detected in the process S3 is determined as it is (determined (certified) as the final detection result).

Then, in a process S55 after the process S53 and the process S54, the detection result processing unit 133b transmits a first detection result notification communication signal to the management server apparatus SVa through the SU communication IF unit 14. FIG. That is, in the process S55 after the process S53 is executed, the first detection result notification communication signal contains the sensor ID of the own machine, the suspicion of leaving the bed, the suspicion of falling, and the suspicion of falling, and the target image. On the other hand, in the process S55 after the process S54 is executed, the first detection result notification communication signal contains the sensor ID of the own machine, any one of leaving the bed, falling, and falling, and the target image.

When receiving the first action detection notification communication signal from the sensor device SUb, the management server device SVa stores the monitoring information contained in the received first action detection notification communication signal in substantially the same manner as in the first embodiment, A second behavior detection notification communication signal based on the received first behavior detection notification communication signal is transmitted to predetermined terminal devices SPb and TAb. Here, in the second embodiment, the predetermined behavior includes not only getting out of bed, falling down, and falling, but also suspected getting up, falling down, and falling down. Any one of getting out of bed, falling, falling, suspicion of getting out of bed, suspicion of falling, and suspicion of falling is stored as information representing the content of the predetermined behavior of the monitored person Ob detected in .

Then, when the terminal devices SPb and TAb receive the second behavior detection notification communication signal, the terminal devices SPb and TAb display the monitoring information contained in the received second behavior detection notification communication signal on the monitoring information display screen. More specifically, in FIG. 17, the terminal devices SPb and TAb determine what is the detection result detected by the sensor device SUb (S61). More specifically, the terminal devices SPb and TAb determine what the information representing the content of the predetermined action contained in the received second action detection notification communication signal is. As a result of this determination, if the information representing the content of the predetermined action is any one of leaving the bed, falling, or falling (getting out of bed, falling, or falling), the terminal devices SPb and TAb send the detection result to the After executing the process S63 for displaying in the 1 display mode, this process ends. On the other hand, as a result of the determination, if the information indicating the content of the predetermined action is any one of suspicion of getting out of bed, suspicion of falling, and suspicion of falling (suspicious of getting out of bed, suspicion of falling, suspicion of falling), terminal device SPb, TAb terminates this process after executing the process S62 of displaying the detection result of suspicion in the second display mode.

In the process S63, the terminal devices SPb and TAb display the monitoring information contained in the received second behavior detection notification communication signal on the monitoring information display screen 51 shown in FIG. 13, for example. This monitoring information display screen 51 displays leaving the bed, falling down, and falling as they are in text, so that the detection results are relatively more reliable than the monitoring information display screens 52 and 53 shown in FIG. represents something.

On the other hand, in the process S63, the terminal devices SPb and TAb display the monitoring information contained in the received second action detection notification communication signal, for example, on the monitoring information display screen 52 shown in FIG. 18A or on the monitoring screen shown in FIG. 18B. It is displayed on the information display screen 53 . In the example shown in FIG. 18, the monitoring information display screens 52 and 53 are displayed on the mobile terminal device TAb. The monitoring information display screen 52 shown in FIG. 18A displays the room name of the room RM in which the predetermined behavior was detected, the name of the detected predetermined behavior, and an exclamation mark (!). On this monitoring information display screen 52, the character attributes (font type, font size, character color and display density (display brightness)) of each character in the room name of the room RM and each character in the action name are displayed. By changing the character attribute of each character displayed on the monitoring information display screen 51 in the first display mode, the monitor (user) can display a relatively low reliability such as an exclamation mark (!). By displaying a specific icon calling attention to, the detection result is a detection result with relatively low reliability compared to the monitoring information display screen 51 shown in FIG. 13 . Each character displayed on the monitoring information display screen 52 shown in FIG. 18A is displayed with a lighter display density compared to the monitoring information display screen 51 shown in FIG. Similar to the monitoring information display screen 51 shown in FIG. 13, the monitoring information display screen 53 shown in FIG. The target image is displayed when the action of is detected. However, in this monitoring information display screen 53, by changing the character attribute of each character from the character attribute of each character represented on the monitoring information display screen 51 in the first display mode, the display size (resolution) of the target image can be increased. is changed to indicate that the detection result has relatively low reliability compared to the monitoring information display screen 51 shown in FIG. 13 . Each character displayed on the monitoring information display screen 53 shown in FIG. 18B is displayed with a character having a smaller number of points than the characters displayed on the monitoring information display screen 51 shown in FIG. It is displayed in a smaller display size (lower resolution) than the display screen 51 . Furthermore, on the monitoring information display screens 52 and 53 shown in FIG. 18, even if the text "suspect" is displayed, the detection results are detected with relatively low reliability compared to the monitoring information display screen 51 shown in FIG. It shows that it is the result. By changing the display mode in this way, the monitor (user) can visually recognize the reliability of the detection result.

The monitored person monitoring support system MSb and the monitored person monitoring support method implemented in the second embodiment change the display mode of the detection result based on the seating detection result. It is possible to recognize the reliability of the detection result based on the seating detection result, and therefore, it is possible to issue a warning more appropriately with the reliability of the detection result.

In the above description, the terminal devices SPb and TAb are displayed in the first display mode or the second display mode depending on whether or not the user is seated in the seating detection result. , a relatively loud notification sound or a relatively quiet notification sound may be output. Furthermore, instead of or in addition to these, the terminal devices SPb and TAb may output a relatively long notification sound or a relatively short notification sound.

FIG. 19 is a diagram for explaining a modification of the second embodiment. FIG. 19A shows a case where the seating detection result indicates no seating, and FIG. 19B shows a case where the seating detection result indicates seating.

For example, since the sensor device SUb has detected that the sensor device SUb has not been seated by the seating detection unit 12, the terminal devices SPb and TAb convert the monitoring information contained in the received second behavior detection notification communication signal into, for example, the monitoring information shown in FIG. In the case of displaying on the display screen 51, as shown in FIG. 19A, the terminal devices SPb and TAb display the monitoring information display screen 51 and also display a relatively loud and long notification sound (for example, a ringing melody). to output On the other hand, since the sensor device SUb has detected that the sensor device SUb is seated by the seating detection unit 12, the terminal devices SPb and TAb convert the monitoring information contained in the received second action detection notification communication signal into the monitoring information shown in FIG. 18B, for example. In the case of displaying on the display screen 53, as shown in FIG. 19B, the terminal devices SPb and TAb display the monitoring information display screen 53 and emit a relatively small and short notification sound (for example, "beep"). ).

Next, another embodiment will be described.

(Third embodiment)
Although the monitored person monitoring support system MSa in the first embodiment processes the detection result by a different processing method of whether or not to display it on the terminal device based on the seating detection result, the monitored person monitoring support system MSa in the third embodiment The person monitoring support system processes the detection result by a different processing method depending on whether or not the management server device manages the detection result based on the seating detection result.

For example, as shown in FIG. 1, the monitored person monitoring support system MSc in the third embodiment includes one or a plurality of sensor devices SUc (SUc-1 to SUc-4), a management server device SVc, It comprises a fixed terminal device SPa, one or more mobile terminal devices TAa (TAa-1, TAa-2), and a private branch exchange CX, which are communicably connected via a network NW. The fixed terminal device SPa and the mobile terminal device TAa in the monitored person monitoring support system MSc of the third embodiment are respectively the fixed terminal device SPa and the mobile terminal device TAa in the monitored person monitoring support system MSa of the first embodiment. Since it is the same, the description is omitted.

For example, as shown in FIG. 2, the sensor device SUc in the monitored person monitoring support system MSc of the third embodiment includes an imaging unit 11, a seating detection unit 12, an SU control processing unit 13c, and an SU communication IF unit. 14 and an SU storage unit 15 . The imaging unit 11, the seating detection unit 12, the SU communication IF unit 14, and the SU storage unit 15 in the sensor device SUc of the third embodiment correspond to the imaging unit 11 and the seating detection unit 12 in the sensor device SUa of the first embodiment, respectively. , the SU communication IF unit 14 and the SU storage unit 15, the description thereof will be omitted.

The SU control processing unit 13c controls each unit of the sensor unit SUc in accordance with the function of each unit, detects a predetermined behavior related to the monitored person Ob, and outputs the detection result together with an image to the management server device. Circuit for sending to SVc. Then, in the present embodiment, the SU control processing unit 13c detects that the monitored person Ob is seated, and transmits the detection result to the management server device SVc. Different processing methods are used based on the detection results. The SU control processing unit 13c functionally includes an SU control unit 131, an action detection processing unit 132, and a detection result processing unit 133c by executing a control processing program. The SU control unit 131 and the action detection processing unit 132 in the SU control processing unit 13c of the third embodiment are similar to the SU control unit 131 and the action detection processing unit 132 in the SU control processing unit 13a of the first embodiment, respectively. Therefore, the description is omitted.

The detection result processing unit 133 c processes the detection result of the action detection processing unit 132 by different processing methods based on the seating detection result of the seating detection unit 12 . More specifically, in the present embodiment, the detection result processing unit 133c stores and manages the detection result in the management server device SVc when the seating detection result indicates that the monitored person Ob is not seated. , and when the result of the detection of seating is that the monitored person Ob is seated, the detection result is processed by a sixth processing method in which the management server device SVc does not store and manage the detection result. More specifically, the sixth processing method is a processing method that does not transmit the detection result to the management server device SVc. That is, in the fifth processing method, when the behavior detection processing unit 132 detects the predetermined behavior and the seating detection result is not that the monitored person Ob is seated, the detection result processing unit 133c performs the first behavior detection. A notification communication signal is transmitted to the management server device SVc by the SU communication IF unit 14 . In the fifth processing method, even if the behavior detection processing unit 132 detects the predetermined behavior, if the seating detection result is that the monitored person Ob is seated, the detection result processing unit 133c performs the first behavior Do not send detection notification communication signals.

Therefore, as a result, the detection result processing unit 133c is realized by the detection result processing unit 133a ((detection result processing unit 133c)=(detection result processing unit 133a)). Therefore, the monitored person monitoring support system MSc in the third embodiment can be realized by using the sensor device SUa and the management server device SVa in the first embodiment as the sensor device SUc and the management server device SVc, respectively. Therefore, description of the management server device SVc is omitted.

The monitored person monitoring support system MSb and the monitored person monitoring support method implemented therein in the third embodiment control execution or non-execution of storing the detection result based on the seating detection result. Only highly reliable detection results can be stored and managed.

In the above-described embodiment, the detection result processing unit 133c is provided in the sensor device SUc, but it may be provided in the management server device SVc instead of the sensor device SUc.

FIG. 20 is a sequence diagram showing the operation of the modified monitored person monitoring system in the third embodiment.

When the management server device SVc includes a detection result processing unit, first, the detection result processing unit 133c is omitted from the sensor device SUc, and the action detection processing unit 132 instead of the detection result processing unit 133c transmits the first detection result notification communication signal. It is transmitted to the management server device SVc. In this case, the first detection result notification communication signal includes the sensor ID of the device itself, information indicating the content of a predetermined action of the detected monitored person Ob (in the present embodiment, information indicating the content of the predetermined action of the monitored person Ob (in this embodiment, out of bed, falling, and falling). any), and the target image used to detect the predetermined action, and further, the seating detection result (in this embodiment, either sitting or not seated) is stored. be. The management server device SVc not only functionally equips the SV control processing unit 22 with the SV control unit 221 and the SV monitoring processing unit 222, but also functionally equips the SV control processing unit 22 with a detection result processing unit. The detection result processing unit in the management server device SVc receives the detection result contained in the first detection result notification communication signal received from the sensor device SUc as information representing the content of the predetermined behavior of the monitored person Ob. Different processing methods are used based on the seating detection result of the seating detection unit 12 contained in the first detection result notification communication signal. More specifically, the detection result processing unit in the management server device SVc stores the detection result in the management server device SVc when the seating detection result indicates that the monitored person Ob is not seated (when the monitored person Ob is not seated). Processing by a fifth processing method for management, and when the result of the detection of seating is that the monitored person Ob is seated (when the person to be monitored Ob is seated), the detection result is not stored in the management server device SVc and is not managed. Treat with the treatment method. That is, in the above description, since the SV monitoring processing unit 222 stores and manages the monitoring information contained in the received first action detection notification communication signal in the SV storage unit 23, the detection result processing unit in the management server device SVc permits the SV monitoring processing unit 222 to store and manage monitoring information when the seating detection result indicates that the monitored person Ob is not seated (when the monitored person Ob is not seated). In the case of being seated (in the case of being seated), storage and management of monitoring information by the SV monitoring processing unit 222 are prohibited, and the monitoring information is discarded.

In the monitored person monitoring support system MSc in such a modified form, when the behavior detection processing unit 132 detects a predetermined behavior and the seating detection unit 12 detects no seating, the first detection result notification communication signal Further, the processes C1 to C5 shown in FIG. 12 are executed, except that the result of the seating detection is stored.

On the other hand, in FIG. 20, when a predetermined action is detected by the action detection processing unit 132 and no seating is detected by the seating detection unit 12 (C31), the sensor unit SUc further indicates that there is seating as the seating detection result. The received first behavior detection notification communication signal is transmitted to the management server device SVc (C32). When the management server device SVc receives the first behavior detection notification communication signal, the management server device SVc discards the monitoring information according to the seating detection result of the presence of the seating contained in the received first behavior detection notification communication signal, and does not store it. Not managed (C33).
