Description

  The present invention relates to a watching device for watching an action of a person who needs assistance.

  For example, in a care facility, in order to grasp the behavior of each of a plurality of caregivers occupying the care facility, the assistant regularly looks around the care facility. However, such a patrol is a heavy burden on the caregiver. Therefore, conventionally, a watching device for watching the behavior of the person being assisted has been proposed (see, for example, Patent Document 1).

  In a conventional monitoring device, a sensor for detecting a person being assisted is disposed in a corridor or the like in a care facility. For example, when the sensor detects a person being assisted at night, the watching device determines that the person being assisted is hesitating and outputs an alarm.

JP 2001-76289 A

  In the conventional watching device described above, the following problems occur. Among a plurality of residents (caregivers) who move into a care facility, there may be a resident who does not have a problem even if he / she acts alone because he / she is relatively healthy. When such a relatively healthy resident walks down a corridor or the like in a nursing facility to go to a toilet at night, for example, an unnecessary alarm is output when the sensor detects the resident.

  The present invention is to solve the above-described problems, and an object of the present invention is to provide a monitoring device that can suppress output of an unnecessary alarm.

  In order to achieve the above object, a watching device according to one aspect of the present invention is a watching device for watching the behavior of a person being assisted, and the helper who assists the person being assisted and the person being assisted behaves. A detection unit that detects the movement trajectory of each of the person being assisted and the person being assisted, and based on the detected movement trajectory of each of the person being assisted and the person being assisted, A determination unit that determines whether or not the specific action corresponding to the movement trajectory is an action accompanied by the assistance of the assistant, and the specific action is determined to be an action accompanied by the assistance of the assistant A storage unit that stores the specific action as a prohibited action that represents an action that the care recipient is prohibited from performing alone, and the prohibited action is stored in the storage unit. , The caretaker alone responds to the prohibited action And an output unit for outputting an alarm when the that action.

  According to this aspect, when the prohibited action is stored in the storage unit, the output unit outputs an alarm when the person being assisted performs an action corresponding to the prohibited action alone. Thereby, since the conditions for outputting an alarm can be limited, the output of an unnecessary alarm can be suppressed.

  For example, in the monitoring device according to an aspect of the present invention, the determination unit further includes, when the movement locus of the person being assisted is detected, based on the detected movement locus and the prohibited action, It is determined whether or not the person being assisted performs an action corresponding to the prohibited action alone, and the output unit determines that the person being assisted alone has taken an action corresponding to the prohibited action. An alarm may be output.

  According to this aspect, the determination unit performs the action corresponding to the prohibited action alone based on the movement trajectory of the helped person detected by the detection unit and the prohibited action stored in the storage unit. It can be determined whether or not.

  For example, in the monitoring device according to one aspect of the present invention, the determination unit can switch the alarm mode on and off, and when the alarm mode is off, the determination unit detects the detected person being assisted And based on the movement trajectory of each of the assistants, it is determined whether the specific action is an action accompanied by the assistance of the assistant, and the storage unit determines that the specific action is the assistant. When the action is determined to be accompanied by assistance, the specific action is stored as the prohibited action, and when the alarm mode is on, the determination unit detects the movement trajectory of the person being assisted And determining whether or not the person being assisted alone has taken an action corresponding to the prohibited action based on the detected movement trajectory and the prohibited action. Respond to the prohibited action It may be configured to output the alarm when it is determined that the action.

  According to this aspect, the determination unit can switch the alarm mode on and off.

  For example, in the monitoring device according to one aspect of the present invention, the storage unit is associated with each of the plurality of movement locus information regarding the movement locus of the person being assisted and each of the plurality of movement locus information and needs assistance. And the assistance information regarding the rejection, and the movement trajectory information corresponding to the assistance information indicating that assistance is required among the plurality of movement trajectory information is stored as the prohibited action, and the determination unit includes: The movement trajectory information that matches the detected movement trajectory is searched from the plurality of movement trajectory information, and when the searched movement trajectory information is the prohibited action, the person being assisted is prohibited alone. You may comprise so that it may determine with having taken action corresponding to action.

  According to this aspect, the determination unit searches the movement trajectory information that matches the movement trajectory detected by the detection unit from the plurality of movement trajectory information, so that the searched movement trajectory information is a prohibited action. Therefore, it can be determined that the person being assisted alone has taken action corresponding to the prohibited action.

  For example, in the monitoring apparatus according to one aspect of the present invention, the output unit does not output the alarm when it is determined that the person being assisted does not perform the action corresponding to the prohibited action alone. It may be configured.

  According to this aspect, the output unit does not output an alarm when it is determined that the person being assisted does not perform an action corresponding to the prohibited action alone. Thus, for example, when a relatively healthy person (that is, forbidden behavior is not set) acts alone, or when the person performs an action corresponding to the prohibited action with the assistance of the assistant For example, the output unit does not output an alarm. As a result, unnecessary alarm output can be suppressed.

  For example, in the monitoring device according to one aspect of the present invention, the storage unit further stores a permitted action representing an action that the person being assisted is permitted to perform alone, and the determination unit further includes: When the person being assisted performs an action accompanied by the assistance of the assistant within a predetermined period, the permission action stored in the storage unit may be changed to the prohibited action.

  According to this aspect, the determination unit changes the permitted behavior stored in the storage unit to the prohibited behavior when the helped person performs an action with the assistance of the assistant within a predetermined period. Thereby, when there is a track record in which a caregiver received assistance from a helper within a predetermined period in the past, it is possible to prohibit the caregiver from acting alone.

  For example, in the monitoring apparatus according to an aspect of the present invention, the determination unit further stores the determination in the storage unit when the person being assisted does not perform the action accompanied by the assistance of the assistant within a predetermined period. You may comprise so that the said prohibition action currently performed may be changed into the said permission action.

  According to this aspect, the determination unit changes the prohibited action stored in the storage unit to the permitted action when the person being assisted does not act with the assistance of the assistant within a predetermined period. Thereby, when a caregiver does not have a track record of receiving assistance from a helper within a predetermined period in the past, the caregiver can be permitted to act alone. As a result, unnecessary alarm output can be more effectively suppressed.

  For example, in the monitoring apparatus according to one aspect of the present invention, the detection unit includes a first sensor that detects the person being present in a first area within a predetermined area, and the first sensor within the predetermined area. A second sensor that detects the person being assisted in a second region different from the first region, and the output unit further detects the person being assisted by the first sensor. The second sensor may output the alarm when the second sensor does not detect the person being assisted until a predetermined time has passed.

  According to this aspect, the output unit issues an alarm when the second sensor does not detect the person being assisted until a predetermined time elapses after the first sensor detects the person being assisted. Output. As a result, for example, when the person being assisted falls between the first area and the second area, an alarm is output, so that the person assisted can quickly rush to the person being assisted.

  Note that the present invention can be realized not only as a monitoring device including such a characteristic processing unit, but also as a monitoring method using steps executed by the characteristic processing unit included in the monitoring device. be able to. It can also be realized as a program for causing a computer to function as a characteristic processing unit included in the monitoring device or a program for causing a computer to execute characteristic steps included in the monitoring method. Such a program can be distributed via a computer-readable non-transitory recording medium such as a CD-ROM (Compact Disc-Read Only Memory) or a communication network such as the Internet. .

  According to the monitoring device according to one embodiment of the present invention, it is possible to suppress unnecessary alarm output.

And the assistant 26 are detected.

  As illustrated in FIG. 1, the server 24 includes a first memory 40, a second memory 42, a third memory 44 (storage unit), a determination unit 46, and an output unit 48.

  In the first memory 40, detection signals output from each of the plurality of sensors 8 to 22 are stored as sensor information. This sensor information includes log data indicating which sensor among the plurality of sensors 8 to 22 receives radio waves from the IC tag of the person being assisted 6 (or radio waves from the IC tag of the assistant 26) at which time. Contains.

  Facility information is stored in the second memory 42. The facility information includes map information in the care facility 4 and data related to the locations where the plurality of sensors 8 to 22 are arranged.

  The third memory 44 stores caregiver information and caregiver information. The assistant information includes data related to the IC tag number of the assistant 26. Note that one IC tag number is assigned to each of the plurality of assistants 26. As shown in FIG. 3, the person being assisted includes IC tag number information, movement trajectory information, and assistance information. The IC tag number information is data relating to the IC tag number of the person being assisted 6. Note that one IC tag number is assigned to each of the plurality of care recipients 6. The movement trajectory information is data relating to the movement trajectory of the person being assisted 6 detected by the plurality of sensors 8 to 22 when the alarm mode (described later) is turned off. The assistance information is data relating to necessity of assistance associated with each of a plurality of pieces of movement trajectory information.

  Note that movement trajectory information corresponding to assistance information indicating that assistance is required among a plurality of movement trajectory information is stored as prohibited actions. That is, the prohibited action represents an action that the person being assisted 6 is prohibited from performing alone (that is, without the assistance of the assistant 26). On the other hand, movement trajectory information corresponding to assistance information indicating that no assistance is required among a plurality of movement trajectory information is stored as permitted actions. That is, the permitted action represents an action that the person being assisted 6 is permitted to perform alone.

  In the example shown in FIG. 3, for the caregiver 6 with the IC tag number “0001”, movement between the room 28 and the toilet 30 and movement between the toilet 30 and the dining room 34 are prohibited actions in the third memory 44. The movement between the room 28 and the canteen 34 is stored in the third memory 44 as a permitted action. On the other hand, for the caregiver 6 with the IC tag number “0002”, movement between the room 28 and the toilet 30 is stored in the third memory 44 as a prohibited action.

  The determination unit 46 switches the alarm mode on and off according to the time zone. Note that the alarm mode is a mode in which an alarm signal (alarm) is output from the output unit 48 (described later) when the person being assisted 6 performs an action corresponding to the prohibited action alone. The determination unit 46 switches off the alarm mode in the daytime period (for example, 7:00 am to 7:00 pm) and switches the alarm mode on in the night time period (for example, 7:00 pm to 7:00 am). .

  When the alarm mode is off, the determination unit 46 is based on the sensor information stored in the first memory 40 and the facility information stored in the second memory 42, and the person being assisted is stored in the third memory 44. Update information. Further, when the alarm mode is on, the determination unit 46 includes sensor information stored in the first memory 40, facility information stored in the second memory 42, assistant information stored in the third memory 44, and Based on the person-to-be-assisted information, it is determined whether or not the person-to-be-assisted 6 has performed an action corresponding to the prohibited action alone.

  The output unit 48 outputs an alarm signal to the outside when the determination unit 46 determines that the person being assisted 6 has taken an action corresponding to the prohibited action when the alarm mode is on. That is, the output unit 48 switches between outputting and not outputting an alarm signal based on the determination result of the determination unit 46. This warning signal is a signal indicating that the person being assisted 6 has taken an action corresponding to the prohibited action alone. The alarm signal from the output unit 48 is output, for example, to an alarm lamp (not shown) installed at a care station in the care facility 4 where the assistant 26 is waiting. The alarm lamp is turned off when an alarm signal is not output from the output unit 48, and blinks (or lights) when an alarm signal is output from the output unit 48. The caregiver 26 can know that the person being assisted 6 has taken an action corresponding to the prohibited action by blinking the warning lamp.

[2. Operation of the monitoring device]
Next, the operation of the watching device 2 described above will be described with reference to FIGS. 2 and 4 to 6. FIG. 4 is a flowchart showing an operation flow of the monitoring device according to the first embodiment when the alarm mode is off. FIG. 5 is a schematic diagram illustrating an example of the behavior of the person being assisted when the alarm mode is on. FIG. 6 is a flowchart showing a flow of operation of the watching device according to Embodiment 1 when the alarm mode is on.

[2-1. Operation when alarm mode is off]
First, the operation of the watching device 2 when the alarm mode is off will be described with reference to FIGS. 2 and 4.

  When the daytime period is entered, the determination unit 46 switches off the alarm mode (S1). When the attendant 6 moves (behaves) from the room 28 to the toilet 30 when the alarm mode is off, each of the plurality of sensors 8 to 14 sequentially receives radio waves from the IC tag of the attendant 6. Thus, the person being assisted 6 moving from the room 28 to the toilet 30 is detected (YES in S2). At this time, detection signals from each of the plurality of sensors 8 to 14 are stored as sensor information in the first memory 40. The determination unit 46 determines that the person being assisted 6 has moved from the room 28 to the toilet 30 based on the sensor information stored in the first memory 40 and the facility information stored in the second memory 42 ( S <b> 3), “room 28 to toilet 30” is added to the movement trajectory information of the person being assisted stored in the third memory 44.

  Here, as shown in FIG. 2, when the action of the person being assisted 6 (that is, the specific action corresponding to the movement locus of the room 28 to the toilet 30) is accompanied by the assistance of the assistant 26, Each of the sensors 8 to 14 detects the assistant 26 moving from the room 28 to the toilet 30 by receiving radio waves from the IC tag of the assistant 26 in order (YES in S4). Accordingly, the determination unit 46 determines that the person being assisted 6 has moved (behaved) from the room 28 to the toilet 30 with the assistance of the assistant 26 (S5), and the movement locus of “room 28 to toilet 30”. The “necessary assistance” is stored in the third memory 44 as assistance information of the care recipient information corresponding to the information. That is, the determination unit 46 stores the movement between the room 28 and the toilet 30 as a prohibited action in the movement trajectory information of the person being assisted in the third memory 44 (S6).

  On the other hand, when the action of the person being assisted 6 is not accompanied by the assistance of the assistant 26, each of the plurality of sensors 8 to 14 does not detect the assistant 26 (NO in S4). As a result, the determination unit 46 determines that the person being assisted 6 has moved (behaves) from the room 28 to the toilet 30 alone (S7), and the person being assisted corresponds to the movement trajectory information of “room 28 to toilet 30”. “Assistance unnecessary” is stored in the third memory 44 as assistance information of the person information. That is, the determination unit 46 stores the movement between the room 28 and the toilet 30 as the permitted action in the movement trajectory information of the person being assisted in the third memory 44 (S8).

[2-2. Operation when alarm mode is on]
Next, the operation of the watching device 2 when the alarm mode is on will be described with reference to FIGS. 5 and 6.

  When the night time zone is entered, the determination unit 46 switches on the alarm mode (S11). When the person being assisted 6 moves from the room 28 to the toilet 30, each of the plurality of sensors 8 to 14 receives the radio wave from the IC tag of the person assisted 6 in order, thereby the room 28 to the bathroom 30. The moving person 6 is detected (YES in S12). At this time, detection signals from each of the plurality of sensors 8 to 14 are stored as sensor information in the first memory 40. The determination unit 46 determines that the person being assisted 6 has moved from the room 28 to the toilet 30 based on the sensor information stored in the first memory 40 and the facility information stored in the second memory 42 (S13). ).

  Furthermore, the determination unit 46 determines whether or not the movement of the person being assisted 6 coincides with the prohibited action based on the person assisted information stored in the third memory 44 (S14). That is, the determination unit 46 searches the movement locus information that matches the movement locus of the person being assisted 6 detected by the plurality of sensors 8 to 14 from the plurality of movement locus information, and the searched movement locus information is prohibited behavior. If it is, it is determined that the person being assisted 6 has performed an action corresponding to the prohibited action alone.

  When the detected movement locus of the person being assisted 6 does not match the prohibited action (in other words, when the movement locus of the assisted person 6 being detected matches the permission action) (NO in S14), the output unit 48 Does not output an alarm signal (S15).

  On the other hand, when the detected movement trajectory of the person to be assisted 6 matches the prohibited action (YES in S14), the determination unit 46 determines whether or not each of the plurality of sensors 8 to 14 has detected the assistant 26. Determine (S16). When the movement of the person being assisted 6 is accompanied by the assistance of the assistant 26, each of the plurality of sensors 8 to 14 receives the radio wave from the IC tag of the assistant 26 in order, and thereby from the room 28. The assistant 26 who moves to the toilet 30 is detected (YES in S16). Accordingly, the determination unit 46 determines that the person being assisted 6 has moved (behaved) from the room 28 to the toilet 30 with the assistance of the assistant 26 (S17). In this case, the output unit 48 does not output an alarm signal (S15).

  As shown in FIG. 5, when the person being assisted 6 moves alone from the room 28 to the toilet 30, each of the plurality of sensors 8 to 14 does not detect the assistant 26 (NO in S <b> 16). Accordingly, the determination unit 46 determines that the person being assisted 6 has moved (behaved) from the room 28 to the toilet 30 alone (S18). In this case, the output unit 48 outputs an alarm signal (S19).

[3. effect]
Next, the effect obtained by the watching device 2 of this Embodiment is demonstrated. As described above, when the person being assisted 6 moves from the room 28 to the toilet 30 with the assistance of the assistant 26 when the alarm mode is off, each of the plurality of sensors 8 to 14 is in turn from the room 28. The person being assisted 6 and the person 26 who move to the toilet 30 are detected. Thereby, the determination unit 46 stores the movement between the room 28 and the toilet 30 as a prohibited action in the movement trajectory information of the person being assisted in the third memory 44.

  Thereafter, when the movement trajectory of the person being assisted 6 detected by the plurality of sensors 8 to 14 coincides with the prohibited action when the alarm mode is turned on, the determination unit 46 responds to the prohibited action by the person being assisted alone. It is determined that you have acted. The output unit 48 outputs an alarm signal when it is determined that the person being assisted 6 has performed an action corresponding to the prohibited action alone.

  Therefore, when the alarm mode is on, for example, when the person being assisted 6 performs an action corresponding to the permitted action alone, or when the person assisted 6 performs an action corresponding to the prohibited action with the assistance of the assistant 26. Since no alarm signal is output, unnecessary alarm signal output can be suppressed.

(Modification of Embodiment 1)
Next, the configuration of the watching device 2 according to the modification of the first embodiment will be described with reference to FIGS. 1 and 7 to 9. FIG. 7 is a diagram illustrating an example of the person being assisted stored in the second memory of the watching device according to the modification of the first embodiment. FIG. 8 is a schematic diagram illustrating an example of the behavior of the person being assisted when the alarm mode is on. FIG. 9 is a flowchart showing a flow of operation of the watching device according to the modification of the first embodiment when the alarm mode is on. In this modification, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 7, in the watching device 2 of this modification, only the movement between the room 28 and the toilet 30 is stored in the third memory 44 as the permitted action for the caregiver 6 with the IC tag number “0001”. In addition, other actions such as movement between the toilet 30 and the canteen 34 and movement between the room 28 and the canteen 34 are respectively stored in the third memory 44 as prohibited actions.

  Next, the operation of the watching device 2 when the alarm mode is on will be described with reference to FIGS. 8 and 9. When the night time zone is entered, the determination unit 46 switches on the alarm mode (S21). When the person being assisted 6 exits from the entrance of the room 28, the sensor 8 detects the person assisted 6 (S22).

  As shown by a solid line arrow P in FIG. 8, when the person to be assisted 6 moves from the room 28 to the toilet 30, each of the plurality of sensors 8 to 14 moves in turn from the room 28 to the toilet 30. The assistant 6 is detected (YES in S23). At this time, if the person being assisted 6 is not moving along a route other than the route of “room 28 to toilet 30”, the sensor 22 does not detect the person assisted 6 (NO in S24). The determination unit 46 determines that the person being assisted 6 has moved from the room 28 to the toilet 30 based on the sensor information stored in the first memory 40 and the facility information stored in the second memory 42 (S25). ). At this time, since the movement trajectory of the person being assisted 6 detected by the plurality of sensors 8 to 14 does not match the prohibited action, the output unit 48 does not output an alarm signal (S26).

  Returning to step S24, as shown by the broken arrow Q in FIG. 8, after the person being assisted 6 has moved from the room 28 to the toilet 30, the sensor 30 has moved to the dining room 34 from the toilet 30. 22 detects the person being assisted 6 (YES in S24). At this time, when the sensor 22 detects the assistant 26 (YES in S27), the determination unit 46 determines that the person being assisted 6 is accompanied by the assistance of the assistant 26, except for the route of “room 28 to toilet 30”. It is determined that the route has been moved (behaved) (S28). In this case, the output unit 48 does not output an alarm signal (S26). On the other hand, when the sensor 22 does not detect the assistant 26 (NO in S27), the determination unit 46 moves (behaves) a route other than the route of “room 28 to toilet 30” alone by the person being assisted 6. (S29). In this case, the output unit 48 outputs an alarm signal (S30).

  Returning to step S23, as indicated by the broken-line arrow R in FIG. 8, when the person being assisted 6 tries to move from the room 28 toward the dining room 34, the plurality of sensors 10 are displayed. 14 to 14 do not detect the person being assisted (NO in S23), and the sensor 16 detects the person being assisted (S31). At this time, when the sensor 16 detects the assistant 26 (YES in S32), the determination unit 46 determines that the person being assisted 6 is accompanied by the assistance of the assistant 26, except for the route of “room 28 to toilet 30”. It is determined that the route has been moved (behaved) (S28). In this case, the output unit 48 does not output an alarm signal (S26). On the other hand, when the sensor 16 does not detect the assistant 26 (NO in S32), the determination unit 46 moves (behaves) a route other than the route of “room 28 to toilet 30” alone by the person being assisted 6. (S29). In this case, the output unit 48 outputs an alarm signal (S30).

(Embodiment 2)
Next, the configuration of the watching device 2A (see FIG. 1) according to Embodiment 2 will be described with reference to FIGS. FIG. 10 is a schematic diagram illustrating an example of the behavior of the person being assisted when the alarm mode is on. FIG. 11 is a flowchart showing an operation flow of the monitoring apparatus according to the second embodiment when the alarm mode is on. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 10, the sensor 10 (first sensor) detects the person being assisted 6 present in the first region 50 in the care facility 4 (predetermined area). The sensor 12 (second sensor) detects the person being assisted 6 present in a second area 52 different from the first area 50 in the care facility 4.

  The determination unit 46A (see FIG. 1) passes a predetermined time (for example, 5 minutes) after one of a pair of adjacent sensors (sensor 10 in the present embodiment) detects the person being assisted 6. Until the other person (sensor 12 in the present embodiment) of the pair of sensors does not detect the person being assisted 6, the person being assisted by the first area 50 and the second area 52 It is determined that it has fallen between.

  The output unit 48 </ b> A (see FIG. 1) outputs an alarm signal when it is determined that the person being assisted 6 falls between the first area 50 and the second area 52.

  Next, the operation of the watching device 2A when the alarm mode is on will be described with reference to FIG. In the present embodiment, it is assumed that movement between the room 28 and the toilet 30 is stored in the third memory 44 as the permitted action for the care recipient 6. First, when the person being assisted 6 exits from the entrance of the room 28, the sensor 8 detects the person assisted 6 (S41). Thereafter, when the person being assisted 26 moves from the room 28 toward the toilet 30, the sensor 10 detects the person assisted 6 (S42).

  If the sensor 12 does not detect the person being assisted 6 after the sensor 10 detects the person being assisted 6 until a predetermined time has elapsed (YES in S43), the determination unit 46A Is determined to have fallen between the first region 50 and the second region 52. In this case, the output unit 48A outputs an alarm signal (S44). On the other hand, if the sensor 12 detects the person being assisted 6 after the sensor 10 detects the person being assisted 6 until a predetermined time has elapsed (NO in S43), the output unit 48A outputs an alarm signal. Do not output (S45).

  When the sensor 8 and the sensor 10 detect the assistant 26, that is, when the person being assisted 6 moves from the room 28 toward the toilet 30 with the assistance of the assistant 26, an alarm signal is output. You may extend the said predetermined time until it does. Alternatively, for example, when the sensor 10 (or the sensor 14) arranged in the vicinity of the place where the person being assisted 6 has fallen down detects the person 26, that is, after the person assisted 6 has fallen, When passing near the assistant 6, the predetermined time until the alarm signal is output may be extended.

(Modification)

  For example, the determination unit 46 (46 </ b> A) is stored in the third memory 44 when the person being assisted 6 performs an action with the assistance of the assistant 26 within a predetermined period in the past (for example, six months). You may make it change the permission action of care recipient information into a prohibition action. Thereby, when there is a track record in which the person being assisted 6 has been assisted by the assistant 26 within a predetermined period in the past, the person being assisted 6 can be prohibited from acting alone.

  In addition, for example, the determination unit 46 (46 </ b> A) further determines that the third memory is used when the person being assisted 6 does not act with the assistance of the assistant 26 within a predetermined period in the past (for example, six months). You may make it change the prohibition action of the care receiver information memorize | stored in 44 into permission action. Thereby, it is possible to permit the person being assisted 6 to act alone if the person assisted 6 has not received assistance from the person assisted 26 within the predetermined period in the past. As a result, unnecessary alarm output can be more effectively suppressed.
