<<Regarding a surveillance system according to one embodiment of the present invention>>
Hereinafter, one embodiment of the present invention (hereinafter referred to as the present embodiment) will be described with reference to the accompanying drawings.
In the drawings, the components are shown somewhat simplified and schematic to make the explanation easier to understand, and the sizes (dimensions) of the components and the spacing between the components shown in the drawings are different from the actual ones.

In the following explanation, the monitoring system will be described using a monitoring target person present in a room in a building such as a house as an example. However, the present invention is not particularly limited to a specific building structure as long as it is a room, and can also be applied to buildings other than houses, such as rooms in hospitals and nursing homes.
Furthermore, in the monitoring system, the person to be monitored is not particularly limited in terms of gender, age, etc. Furthermore, the health condition of the person to be monitored is not particularly limited either, and the person to be monitored may be a sick person, an injured person, a person undergoing rehabilitation, a person under observation, a person requiring nursing care, or a person requiring care.

FIG. 1 is a schematic diagram showing a first example of a monitoring system according to an embodiment of the present invention.
The monitoring system 10 shown in FIG. 1 monitors a monitoring target H present in a room 11 a of a room 11 , and includes an output device 12 .
The room 11 is the space where the monitored person H lives, but is not particularly limited thereto and may be a room in one's own home, a room in a nursing home, or a room in a hospital.
The monitoring system 10 is provided in a room 11a with a bed 13, a toilet 14, and a door 15. Although not shown, a mattress, futon, or the like is laid on the bed 13.
Although not shown, a light is provided on the ceiling in the room 11. Although not shown, the room 11 is also provided with a window that allows light to enter and a curtain that can adjust the amount of light entering through the window.
The monitored person H can enter and exit the room 11 by opening and closing the door 15. The size of the room 11 is not particularly limited.

A measuring instrument 16 for measuring a plurality of monitoring items in the room 11a is provided in the interior 11a of the room 11. The measuring instrument 16 outputs signals corresponding to the measurement results of the plurality of monitoring items.
The measuring instrument 16 includes a plurality of sensors arranged at different positions in the room 11a, and each sensor measures a corresponding monitoring item. The measuring instrument 16 has various sensors corresponding to the monitoring items. The type of sensor is not particularly limited as long as it measures the monitoring item, and a sensor corresponding to the monitoring item is used as appropriate. Measurements by the measuring instrument 16 also include human detection using the human presence sensor 16c described below. Measurements by the measuring instrument 16 include "the presence or absence of a person" and "whether a human body has passed through a specified location." The number of sensors is also not particularly limited, and a number of sensors corresponding to the monitoring items is used as appropriate.

The monitored items are the behavior of the monitored person H in the room 11a and the biological information of the monitored person H. Specifically, the monitored items include, but are not limited to, the below-described "turning over in bed,""sittingup,""standingup,""walkingspeed," and "blood pressure." Other monitored items include, for example, walking distance, time spent in front of the door, number of times the door is opened and closed, number of times moving from the bed to the toilet, pulse rate, respiratory rate, and body temperature.
Among the monitoring items, items related to the behavior of the monitoring target person H are called behavior items. The behavior items include, for example, turning over in bed, getting up, standing up, walking, walking speed, walking distance, time spent in front of the door, number of times the door is opened and closed, and number of times the person moves from the bed to the toilet. The behavior items correspond to the behavior information described below.

As the measuring instrument 16, for example, a millimeter wave sensor 16a is provided in the room 11a. This makes it possible to measure the blood pressure of the person being monitored H. The millimeter wave sensor 16a can also identify the position of the person being monitored H in the room 11a. The millimeter wave sensor 16a can also measure the walking speed of the person being monitored H. This makes it possible to measure the position of the person being monitored H in the room 11a and the time that the person being monitored H stays at that position.
The millimeter-wave sensor 16a uses millimeter waves to measure small movements of 0.1 to 0.5 millimeters that the heart exerts on the surface of the human body due to heart movement, and obtains the cardiac cycle or contraction time. The millimeter-wave sensor 16a then analyzes the data obtained by the millimeter waves, such as the cardiac cycle or contraction time, to obtain the systolic blood pressure and mean blood pressure.

Furthermore, a biological information sensor 16b is provided under the mattress (not shown) of the bed 13. The biological information sensor 16b measures the pulse rate and respiratory rate of the monitoring subject H lying in the bed 13, as well as body movements such as turning over in bed, the time when the monitoring subject H gets up from the bed 13, and the time when the monitoring subject H gets out of bed 13. The biological information sensor 16b is in the form of a sheet, and a known sensor used in nursing care can be used. Since the biological information sensor 16b measures the monitoring subject H while he is lying on the mattress, it does not interfere with his daily life.
Furthermore, a human presence sensor 16c is provided in the toilet 14. This makes it possible to determine whether or not the person to be monitored H is present in the toilet 14, and to measure the amount of time the person to be monitored H has been in the toilet 14.

An opening/closing sensor 16d is provided on the door 15. The opening/closing sensor 16d can determine whether the door 15 is open or closed. Meanwhile, as described above, the millimeter wave sensor 16a can identify the position of the monitored person H in the room 11a, and therefore can determine whether the monitored person H has moved from the bed 13 to in front of the door 15. For example, if the millimeter wave sensor 16a determines that the monitored person H has moved from the bed 13 to in front of the door 15, the opening/closing sensor 16d detects that the door 15 has opened, and the millimeter wave sensor 16a determines that the monitored person H is not in front of the door 15 after a predetermined time has elapsed, it is determined that the monitored person H has left the room 11. On the other hand, if the millimeter wave sensor 16a determines that the monitored person H is not in front of the door 15, the opening of the door 15 is detected by the opening/closing sensor 16d, and after a predetermined time has passed, the millimeter wave sensor 16a determines that the monitored person H has moved from the door 15 toward the bed 13, then it is determined that the monitored person H has entered the room 11. By combining the opening/closing sensor 16d and the millimeter wave sensor 16a in this way, it is possible to determine whether the monitored person H is present in the room, and also to determine the time the monitored person H is present and the time the monitored person H is outside the room 11.

The measuring instrument 16 outputs signals corresponding to the measurement results of the multiple monitoring items to the receiving unit 20 of the output device 12 via wired, wireless, or communication, or via the Internet.
When a signal is output to the output device 12 wirelessly, a transmitter (not shown) is provided for each of the sensors of the measuring instrument 16, and the transmitter outputs the signal to the receiver 20 of the output device 12.
The sensing interval of the measuring instrument 16 is not particularly limited, but is determined appropriately depending on whether it is necessary to frequently check the condition of the person to be monitored H, the processing capabilities of the various sensors of the measuring instrument, and the information processing capabilities of the output device 12. Furthermore, the sensing interval of the measuring instrument 16 may be changed depending on the time of day.

The output device 12 outputs monitoring item information corresponding to the measurement results of the plurality of monitoring items based on signals corresponding to the measurement results of the plurality of monitoring items by the measuring instrument 16 .
The output device 12 includes a receiving unit 20, a processing unit 22, a memory 24 (storage unit), and a control unit 26, and further includes a display unit 27 and an input unit 28. The receiving unit 20, the processing unit 22, and the memory 24 are controlled by the control unit 26.
The output device 12 receives signals corresponding to the measurement results of the multiple monitoring items measured by the measuring instruments 16 as input to the receiving unit 20. The output device 12 does not need to be adjacent to the room 11, and may be located in a building separate from the building in which the room 11 is located, or may be located in a remote location, as long as the receiving unit 20 can receive signals corresponding to the measurement results of the multiple monitoring items measured by the measuring instruments 16. For example, the output device 12 may be located in a remote location, such as in a different city or town from the room 11.

The receiving unit 20 receives signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16. The receiving unit 20 also records the time at which the signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16 are received.
The receiving unit 20 is configured to receive signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16 via wired, wireless, communication, or internet output. If the output is wired, the receiving unit 20 receives the signals. If the output is wireless or via communication, the receiving unit 20 has a converter that receives radio waves containing information about the transmitted signals and converts them into signals. If the output is via the internet, the receiving unit 20 is connected to the internet, and thereby receives signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16. Furthermore, in the case of internet output as described above, the signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16 may be output to a server on the cloud, and then the receiving unit 20 may access the server on the cloud to receive the signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16.
The signal corresponding to the measurement results of the plurality of monitoring items by the measuring instrument 16 received by the receiving unit 20 and the time of reception may be stored in the memory 24 .

The processing unit 22 obtains monitoring item information corresponding to the measurement results from signals corresponding to the measurement results of the multiple monitoring items by the measuring instrument 16. Specifically, the blood pressure and walking speed of the monitoring target H can be obtained from the signal of the millimeter wave sensor 16a. In addition, the position of the monitoring target H in the room 11a and the time spent at that position can be measured from the signal of the millimeter wave sensor 16a.
From the signal of the biological information sensor 16b, the pulse rate and respiratory rate of the monitoring target person H lying in bed 13, as well as the time when he/she got up from bed 13 and the time when he/she left bed 13 can be obtained.
From the signal of the human presence sensor 16c, whether or not the person to be monitored H is present in the toilet 14 and the time spent by the person to be monitored H in the toilet 14 can be obtained.
From the signal of the open/close sensor 16d, it is possible to obtain whether or not the person to be monitored H is present in the room, the time the person to be monitored H is present in the room, and the time the person to be monitored H is outside the room 11.
Among the monitoring item information, information relating to the behavior of the monitored person H is referred to as behavior information. Among the monitoring item information, behavior information relating to the behavior of the monitored person H includes turning over in bed, getting up, standing up, walking, walking speed, time spent in front of the door, number of times the door is opened and closed, number of times moving from the bed to the toilet, etc.

The processing unit 22 performs signal processing according to signals from the various sensors of the measuring instrument 16 to obtain multiple pieces of monitoring item information for the monitoring subject H. Furthermore, the multiple pieces of monitoring item information for the monitoring subject H are stored in the memory 24, for example, for each monitoring subject H. This allows the multiple pieces of monitoring item information for the monitoring subject H to be compiled into a database, which is stored in the memory 24 as a library.
The output device 12 (processing unit 22) causes the display unit 27 to display a display image including multiple pieces of monitoring item information for the monitoring target H stored as a library from the memory 24. At this time, the output device 12 (processing unit 22) causes a display image including monitoring item information for each of the multiple monitoring items for the monitoring target H to be displayed on the screen (not shown) of the display unit 27. Note that the method for displaying the monitoring item information in the display image is not particularly limited, and for example, it may be displayed as in a display image 30 shown in FIG. 2 , which will be described later.

As a display format for displaying the display image including the monitoring item information for each of the multiple monitoring items on the screen, it is preferable that the display image be displayed on the same screen, in order to make it easier to grasp the monitoring items.
Here, "the same screen" means that the information is displayed on one display. Incidentally, displaying in one display area (window) within one display also corresponds to "displaying on the same screen." Furthermore, displaying in each of multiple display areas within one display also corresponds to "displaying on the same screen." In addition, when there are multiple displays, displaying on each of the multiple displays also corresponds to "displaying on the same screen." In addition, when multiple displays are combined into one display, displaying an image including monitoring item information on the multiple displays also corresponds to "displaying on the same screen."
The display unit 27 is not limited to displaying a display image including monitoring item information for each of the above-mentioned multiple monitoring items, but also displays information that is displayed on a general personal computer, such as information input to the output device 12.

As described above, the memory 24 stores signals corresponding to the measurement results of multiple monitoring items by the measuring instrument 16 and the time of reception. It also stores multiple monitoring item information for the monitoring subject H. As a result, the multiple monitoring item information for the monitoring subject H is compiled into a database as described above and stored in the memory 24 as a library. In addition to this, for example, average values by age and gender for each monitoring item may also be stored. Furthermore, the memory 24 also stores various information used by the processing unit 22, such as signal processing algorithms corresponding to signals from various sensors. The memory 24 also stores color information set according to the presence or absence of a room, as the occupancy information described below.
The configuration of the memory 24 is not particularly limited as long as it is capable of storing the above-mentioned data, and may be configured to include various storage media such as a DRAM (Dynamic Random Access Memory), an HDD (Hard Disk Drive), and an SSD (Solid State Drive).

The display unit 27 displays, for example, a display image including monitoring item information, and various known displays are used. The number of displays is not particularly limited, and may be one or more, or may be a so-called multi-display. The display unit 27 also includes a device such as a printer for displaying various information on an output medium.
The input unit 28 is an input device such as a mouse and a keyboard for inputting various information in response to an instruction from an operator. A smartphone can also be used as the input unit 28. In this case, an application that functions as a keyboard or the like can be installed in the smartphone.

The output device 12 functionally forms the processing unit 22 by executing a program (computer software) stored in a storage medium such as ROM using the control unit 26. As described above, the output device 12 may be configured as a computer in which each part functions when a program is executed, or as a dedicated device in which each part is configured with a dedicated circuit, or as a server that runs on the cloud.

Next, a specific example of the display of monitoring item information will be described.
The output device 12 (processing unit 22) preferably displays multiple pieces of behavioral information related to the behavior of the monitored person among the monitoring item information using a common time axis, which allows the user to visually and easily grasp the behavior of the monitored person over time.
Furthermore, the output device 12 (processing unit 22) preferably provides a column for each piece of monitoring item information in the display image and displays a marker indicating the monitoring item information in each column, thereby making it easy to visually grasp what actions the monitored person performed and when using the marker.
Furthermore, it is preferable that the markers are rectangular, and each piece of activity information of the monitored person is displayed on the time axis by a marker with a width corresponding to the duration of the activity, which makes it easy to visually grasp not only when the monitored person performed the activity but also the status of each activity.

Figure 2 is a schematic diagram showing an example of the display of monitoring item information in a first example of a monitoring system according to an embodiment of the present invention. Figure 2 shows a display image 30 showing multiple pieces of monitoring item information for monitoring subject H, as described above, displayed on the screen (not shown) of the display unit 27. The display image 30 may be a still image or a video, and is not particularly limited, and may display updated monitoring item information.

2 shows an example in which "turning over,""sittingup,""standingup,""walkingspeed," and "blood pressure" are set as multiple monitoring items. The display image 30 shown in FIG. 2 shows "turning over,""sittingup,""standingup,""walkingspeed," and "blood pressure" as multiple pieces of monitoring item information corresponding to the multiple monitoring items. Of these, "turning over,""sittingup,""standingup," and "walking speed" are multiple pieces of behavioral information related to the behavior of the monitoring subject. "Blood pressure" is biological information of the monitoring subject.
The display image 30 has a column for each monitoring item information, and for example, a column 31a for "turning over," a column 31b for "sitting up," a column 31c for "standing up," a column 31d for "walking speed," and a column 31e for "blood pressure" are arranged in parallel.
In addition, a time axis 32 common to columns 31a to 31e is displayed next to column 31a. By displaying multiple pieces of behavioral information related to the behavior of monitoring target person H using the common time axis 32, it is possible to visually and easily grasp what behavior monitoring target person H has performed over time.
It is preferable that the output device 12 displays markers 33 indicating the monitoring item information in each of the columns 31 a to 31 e. This makes it easy to visually understand what actions the monitoring target person H performed and when, based on the display position of the markers 33.

In the display image 30 shown in FIG. 2, for example, the marker 33 in the "turning over" column 31a indicates that the monitored person H is turning over in his/her sleep.
Here, the marker 33 is, for example, rectangular, and the width _d1 of the marker 33 on the time axis 32 indicates the time spent tossing and turning. A wider marker 33 indicates a longer time spent tossing and turning, and the width of the marker 33 can be used to visually grasp the time spent tossing and turning. Similar to "tossing," other items such as "sitting up,""standingup,""walkingspeed," and "blood pressure" can also be visually grasped from the marker 33 and the width of the marker 33.
For example, the width _d2 of the "standing up" marker 33 is wider than the width _d1 of the "turning over" marker 33, and it is easy to visually understand that the behavior time of "standing up" is longer than that of "turning over".

In addition, in the output device 12, among the monitoring item information, the presence information indicating whether or not the monitored person H is present in the room is set in a color corresponding to whether or not the monitored person H is present in the room, and the color information set in the presence information according to whether or not the monitored person H is present is stored in memory 24.
Since it is possible to visually easily grasp whether or not the person being monitored H is present in the room, it is preferable that the background colors of the fields 31a to 31e be displayed in a color corresponding to whether or not the person being monitored H is present in the room. For example, in the fields 31a to 31e, the background color of the area 34 from midnight to 11:00 is gray, and the background color of the area 35 from 11:00 to 15:00 is transparent. Therefore, it is visually easy to grasp that the person being monitored H was present in the room 11 from midnight to 11:00, but was outside the room 11 from 11:00 to 15:00.

It is also preferable that the markers 33 indicating the monitoring item information be color-coded for each monitoring item information item, using a color displayed based on the value of the monitoring item information. This allows the status of each monitoring item's behavior to be visually and easily grasped for each monitoring item, and, for example, the risk status of monitoring item H for each monitoring item to be visually and easily grasped for each monitoring item. In this case, a color corresponding to the value of each monitoring item information item is preset for each monitoring item information item, and the value and color of the monitoring item information are stored in memory 24. When outputting the monitoring item information, the processing unit 22 references memory 24 and determines the color corresponding to the value of the monitoring item information for each monitoring item information item. The color of the markers 33 is set to the determined color and displayed. The color of the markers 33 is not particularly limited as long as it can identify the value of the monitoring item information. However, it is preferable to use a common color for each monitoring item, such as a color indicating a high value or a color indicating a low value. This allows the value of the monitoring item information to be visually and even more easily grasped based on the color of the markers 33.

For example, in Fig. 2, the color of the marker 33 is displayed by the pattern of the marker 33. A marker 33 with no pattern is blue, a hatched marker 33 is yellow, and a cross-hatched marker 33 is red.
For example, for "standing up," the marker 33 is color-coded, for example, blue, yellow, or red, depending on the time required to stand up. Blue indicates that the time is within the set time, yellow indicates that the time has exceeded the set time but is within the allowable range, and red indicates that the time has exceeded the allowable range. Similarly, for "blood pressure," the marker 33 is color-coded, for example, blue, yellow, or red, depending on the value of systolic blood pressure. Blue indicates that the systolic blood pressure value is within the normal range, yellow indicates that the systolic blood pressure value exceeds the normal range but is within the allowable range, and red indicates that the systolic blood pressure value exceeds the allowable range. In this way, by color-coding the marker 33 using colors displayed based on the values of the monitoring item information, it is possible to visually easily grasp the state of each standing up behavior, in addition to knowing when the above-mentioned standing up behavior occurred.

As with "standing up," for actions other than "rolling over,""sittingup," and "walking speed," the marker 33 and the color of the marker 33 can be used to easily visually grasp not only when the action was performed but also the status of each action, making it easy to visually grasp, for example, the risk and other status of the monitored person H for each monitoring item.
Regarding "blood pressure," the time of blood pressure measurement can be determined from the position of the marker 33, and the state of blood pressure can be determined from the color of the marker 33, so the state of blood pressure, such as when blood pressure is high, can be easily visually determined.

Furthermore, by displaying a display image including monitoring item information for each of a plurality of monitoring items on the screen, it is easy to visually grasp the physical condition of the person being monitored, and in the display image 30 of Fig. 2, for example, it can be seen that the person being monitored H is standing up and walking fast in time period _Q1 from 3 o'clock, which makes it possible to infer, for example, that walking assistance is required.
Also, for example, in the time slot _Q2 from 7 o'clock, the blood pressure of the monitored person H is high, and there is a possibility that he has early morning hypertension.
Furthermore, for example, during the time slot _Q3 from 9 pm, it is estimated that the monitored person H turns over a lot in his/her sleep and that the amount of activity during the day is insufficient. In this way, the state of the monitored person H can be easily grasped.

Furthermore, by displaying a display image containing monitoring item information for each of a plurality of monitoring items on the screen, it is easy to visually grasp the physical condition of the person being monitored, making it easier to understand their behavioral patterns and provide nursing care or care at the appropriate time.It is also easy for the person being monitored to understand their own behavior.
Furthermore, if the behavioral patterns are the same or similar, the same response can be given regardless of the person being monitored, thereby making the work of nurses or caregivers more efficient.

<<Other Embodiments>>
Fig. 3 is a schematic diagram showing a second example of a monitoring system according to an embodiment of the present invention. In Fig. 3, the same components as those shown in Fig. 1 are designated by the same reference numerals, and detailed description thereof will be omitted.
The monitoring system 10a shown in Fig. 3 differs from the monitoring system 10 shown in Fig. 1 in that it targets a building 19 having a plurality of rooms 11, that there is one monitoring target H (see Fig. 1) in each room 11, and that the display unit 27 has a single screen on which a plurality of display areas 40 are provided, and displays display images 30 corresponding to the number of monitoring targets H. The rest of the configuration is the same as that of the monitoring system 10 shown in Fig. 1.

3, there are eight rooms 11, eight monitoring targets H, eight display areas 40 on one screen of the display unit 27, and a display image 30 for each monitoring target H is displayed in each of the eight display areas 40. In other words, eight display areas 40 are simultaneously provided on the same screen.
In this way, the monitoring target H is not limited to one person but can be multiple, and by displaying on one screen a display image including each monitoring item information of multiple monitoring targets H, it is possible to visually and easily grasp what actions each monitoring target H took at the same time and what actions they took in chronological order. In addition to when an action was taken, the status of each action can be visually and easily grasped.
Furthermore, it is easy to visually grasp whether each person to be monitored H is present in the room.

Up to this point, we have explained an embodiment of the monitoring system of the present invention, but the above embodiment is merely an example intended to facilitate understanding of the present invention and does not limit the present invention. In other words, the present invention can be modified and improved without departing from its spirit. Furthermore, it goes without saying that the present invention also includes equivalents.
