Abstract

<P>PROBLEM TO BE SOLVED: To burden a monitoring person as less as possible with respect to a target person to be monitored who is less likely to wander and to allow the monitoring person to perform monitoring as minutely as possible with respect to a target person to be monitored who is more likely to wander. <P>SOLUTION: A reader 2 which reads radio device information from an IC tag 1 which a target person to be monitored carries, is installed in a prescribed place. If the place of the reader 2 which has read the radio device information is not included in a permitted movement area, it is informed that the target person has gone out of the permitted movement area, and a history is stored. When a frequency totalized from histories is lower than a prescribed frequency, a pertinent area is set to be wider to reduce notifications about movement of the target person who scarcely goes out of the permitted movement area and is less likely to wander. When the frequency totalized from histories is higher than the prescribed frequency, the pertinent area is set to be narrower to give a notification about a little movement of the target person who frequently goes out of the permitted movement area and is more likely to wander. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a wrinkle detection system for detecting that a patient or a cared person has hesitated in a hospital or a care facility.

  Conventionally, in hospitals and care facilities (hereinafter referred to as “facility”), patients and care recipients (hereinafter referred to as “monitored persons”) sometimes wander away from the bed. When the monitored person is hesitant, there may be a danger to the monitored person depending on the situation around the monitored person. Therefore, when the monitored person is hesitant, it is necessary to inform a health care worker or a caregiver (hereinafter referred to as a supervisor).

  By the way, a behavior detection system that detects that the monitored person is hesitant is known (for example, Patent Document 1). In the behavior detection system described in Patent Document 1, an elderly person who is a person to be monitored holds an ID (Identifier) tag, and a trigger signal transmitter is installed at an entrance / exit of a facility, a restaurant, a room, or the like. The ID tag that has received the trigger signal output from the trigger signal transmitter outputs ID number information indicating the ID number assigned to the own device. In addition, the trigger signal transmitter that has received the ID number information output from the ID tag transmits the ID number information and the location information indicating the location where the device is installed to the management device connected via the network. To do. The management apparatus determines in advance a region where the monitored person can move, and determines whether or not the monitored person has moved out of the movable region based on the received ID number information and location information. When the management device determines that the monitored person has moved out of the movable area, the management device flashes the display and outputs an alarm sound to notify the monitored person that the monitored person is hesitant. Yes. Thereby, the monitoring person can monitor the action of the monitored person without making the monitored person particularly aware.

  By the way, it is assumed that there is a monitored person who rarely leaves a movable area in a facility to which the technique described in Patent Document 1 is applied. Since this monitored person rarely leaves the movable area, it is considered that there is no trap at the moment. However, even with such a monitored person, in the technique described in Patent Document 1, since the notification is performed when leaving the movable region, the monitored person is monitored to confirm the safety of the monitored person. There was a problem that it was necessary to rush to the person in charge and put a burden on the observer.

  Further, it is assumed that there is a person to be monitored who often comes out of a movable area in a facility to which the technique described in Patent Document 1 is applied. This monitored person is likely to be trapped because he often leaves the movable area. However, in the technique described in Patent Document 1, since the notification is not performed when the monitored person does not go out of the movable area, a wrinkled monitored person hesitates in the movable area. However, there was a problem that the notification was not performed and the supervisor could not cope.

JP 2006-236128 A

  The present invention has been made to solve such a problem. For a monitored person who has a low possibility of hesitation, it is possible to hesitate as much as possible and to hesitate. The purpose is to enable the supervisor to monitor as closely as possible for a highly-monitored person.

  In order to solve the above-described problems, in the wrinkle detection system according to the present invention, a wireless device is carried by a person to be monitored, and a reading device that reads wireless device information from the wireless device is installed at a predetermined location in the facility. When the monitored person sets a movable area in the facility and determines that the position of the reading device that reads the wireless device information from the wireless device carried by the monitored person is not included in the set region This is notified, and the frequency at which the monitored person exits the set area is stored. When it is determined that the frequency at which the monitored person has moved out of the movable area is lower than the predetermined frequency, the movable area is set wide for the monitored person so that the monitored person can move. When it is determined that the frequency of exiting the area is higher than a predetermined frequency, the area that can be moved for the monitored person is set to be narrow.

  In the present invention configured as described above, it is determined that there is a low possibility of hesitation for a monitored person whose frequency of exiting a movable area is lower than a predetermined frequency, and a wide range of movable areas is set. Is done. As a result, for a person to be monitored who has a low possibility of hesitation, a wide movable area is set so as to reduce notifications due to coming out of the movable area. Therefore, it is possible to minimize the burden on the monitored person as much as possible. Further, for a monitored person whose frequency of exiting the movable area is higher than a predetermined frequency, the movable area is determined to be narrower because it is determined that the possibility of hesitation is high. As a result, for the person to be monitored who has a high possibility of hesitation, a movable area is set to be narrow, and a notification is given in detail when the person leaves the movable area. Therefore, such a monitored person can be monitored as finely as possible.

In the wireless device number area 35, for example, information such as “M01” is stored as the wireless device number. The reading date and time area 36 stores information such as “7/23 10:00” as the date and time from the movable area.

  The alerting | reporting part 14 is for alert | reporting that the to-be-monitored person is hesitant. The notification unit 14 includes a speaker, a display display, an indicator lamp, and the like, and outputs a ringing tone and voice from the speaker, causes the display display to display a call, and lights or blinks the indicator lamp. And make a notification.

  The tabulation unit 11a tabulates for each IC tag 1 tabulation frequency information indicating the frequency at which the monitored person has moved out of the movable area in a predetermined period from the history information stored in the storage unit 13. Further, in the present embodiment, the predetermined period is, for example, 24 hours until an arbitrarily designated time point. Further, in order for the counting unit 11a to count the counting frequency information, history information corresponding to a period to be counted (in this embodiment, history information for at least 24 hours) needs to be stored in the storage unit 13. There is.

  The control unit 11 causes the counting unit 11a to operate periodically at a predetermined timing (for example, 0:00 every day). Specifically, the control unit 11 calculates a date and time that goes back 24 hours from a predetermined timing, extracts 24 hours of history information from the calculated date and time to a predetermined timing, and extracts the extracted history information Get radio information from The tabulation unit 11a tabulates tabulation frequency information for each IC tag 1 over a predetermined period based on the acquired wireless device information. For example, in the case where the history information shown in FIG. 3C is stored, if the current date and time is 7/24 0:00, the tabulation unit 11a displays the date and time (7/24) retroactive from 7/24 0:00. 23 0:00), and the total frequency information of the radio number M01 is 4 and the total frequency information of the radio number M02 is 1.

  The frequency determination unit 11b determines whether or not the aggregation frequency information aggregated by the aggregation unit 11a is lower than a predetermined frequency. Here, the frequency determination unit 11b starts the operation when the totaling unit 11a totals the total frequency information in a predetermined period. The predetermined frequency is a reference frequency used for widening or narrowing a movable area with respect to the monitored person, and is determined in advance by the monitoring person or the like. The frequency determination unit 11b compares the frequency corresponding to the aggregation frequency information aggregated by the aggregation unit 11a with a predetermined frequency.

  The area setting unit 11c updates the area information of the corresponding IC tag 1 according to the determination result by the frequency determination unit 11b. Here, the area setting unit 11c starts operating when the frequency determination unit 11b executes the determination process. Specifically, the area setting unit 11c refers to the storage unit 13 when the frequency determination unit 11b determines that the frequency corresponding to the aggregation frequency information aggregated by the aggregation unit 11a is lower than a predetermined frequency. The area information stored in association with the wireless device information corresponding to the aggregation frequency information aggregated by the aggregation unit 11a is acquired. The area setting unit 11 c rewrites the area corresponding to the acquired area information into a wide area and stores it in the storage unit 13. Here, each place in the facility set as a wide area is registered in advance by a supervisor or the like.

  For example, assume that the movable areas before rewriting are H1, H2, S, R1, R2, and R3. When the frequency determining unit 11b determines that the frequency corresponding to the total frequency information totaled by the totaling unit 11a is lower than a predetermined frequency, the area setting unit 11c displays the location ( H1, H2, E, S, R1, R2, R3) are stored in the storage unit 13 as a wide area. Here, in the present embodiment, an increase in the number of movable areas is defined as setting a wide area.

  On the other hand, when the frequency determination unit 11b determines that the frequency corresponding to the aggregation frequency information aggregated by the aggregation unit 11a is higher than a predetermined frequency, the area setting unit 11c refers to the storage unit 13 and calculates the aggregation unit The area information stored in association with the wireless device information corresponding to the counting frequency information tabulated in 11a is acquired. The area setting unit 11 c rewrites the area corresponding to the acquired area information into a narrow area and stores it in the storage unit 13. Here, each place in the facility set as a narrow area is registered in advance by a supervisor or the like.

  For example, assume that the movable areas before rewriting are H1, H2, S, R1, R2, and R3. When the frequency determining unit 11b determines that the frequency corresponding to the total frequency information totaled by the totaling unit 11a is higher than a predetermined frequency, the region setting unit 11c displays the location ( R1 only) is stored in the storage unit 13 as a narrow area. Here, in the present embodiment, the reduction in the number of movable areas is defined as setting the areas narrow.

  The heel determination unit 11d includes the location where the reading device 2 that has read the wireless device information is installed in an area that can be moved by the person carrying the IC tag 1 that is specified by the wireless device information. It is determined whether or not. When the I / F unit 12 inputs the wireless device information and the reading device information output from the reading device 2, the control unit 11 refers to the storage unit 13 and stores it in association with the acquired wireless device information. Get region information. In addition, the control unit 11 refers to the storage unit 13 and acquires location information stored in association with the acquired reading device information.

  When the area information and the location information are acquired, the control unit 11 operates the wrinkle determination unit 11d. The eyelid determination unit 11d determines whether or not the location information acquired by the control unit 11 is included in the area information acquired by the control unit 11. When the bag determining unit 11d determines that the location information is included in the area information, the control unit 11 monitors the person carrying the IC tag 1 specified by the wireless device information read by the reading device 2. It is determined that the person is not out of the movable area, and the notification unit 14 is not operated.

  On the other hand, when the bag determining unit 11d determines that the location information is not included in the area information, the control unit 11 carries the IC tag 1 specified by the wireless device information read by the reading device 2. It is determined that the monitored person has come out of the movable area, and the notification unit 14 is operated. And the alerting | reporting part 14 alert | reports that the to-be-monitored person is hesitant. The control unit 11 operates the current date acquisition unit 11e, and the current date acquisition unit 11e acquires current date information indicating the current date from a clock unit (not shown) that measures the current date. The control unit 11 associates the acquired wireless device information with the current date and time information acquired by the current date and time acquisition unit 11 e and stores the information as history information in the storage unit 13.

  When the notification by the notification unit 14 is performed, the supervisor operates an operation unit (not shown) provided in the notification device 10. When the operation unit is operated, the control unit 11 stops the operation of the notification unit 14.

  Next, the region setting process and the wrinkle determination process of the wrinkle detection system according to the present embodiment will be described based on the examples shown in FIGS. Further, in this example, it is assumed that the movable area is H1, H2, S, R1, R2, R3 for the monitored person carrying the IC tag 1 with the radio number M01. In this example, the predetermined frequency is 4.

  First, when the monitored person carrying the IC tag 1 with the wireless device number M01 exits from the room R1 to the hallway H1, the reading device 2a installed in the hallway H1 reads the wireless device information (M01). The reading device 2a that has read the wireless device information outputs the read wireless device information (M01) and its own reading device information (2a) to the notification device 10.

  When the I / F unit 12 of the notification device 10 inputs the wireless device information and the reading device information, the control unit 11 refers to the storage unit 13 and stores the region information associated with the acquired wireless device information (M01). (H1, H2, S, R1, R2, R3) are acquired. Further, the control unit 11 refers to the storage unit 13 and acquires the location information (H1) stored in association with the acquired reading device information (2a). The eyelid determination unit 11d determines whether or not the location information acquired by the control unit 11 is included in the area information acquired by the control unit 11. Here, since the location information is included in the region information, the control unit 11 does not operate the notification unit 14.

  Furthermore, when the monitored person carrying the IC tag 1 with the wireless device number M01 moves from the hallway H1 to the elevator E, the reading device 2c installed in the elevator E reads the wireless device information (M01). The reading device 2c that has read the wireless device information outputs the read wireless device information (M01) and its own reading device information (2c) to the notification device 10.

  When the I / F unit 12 of the notification device 10 inputs the wireless device information and the reading device information, the control unit 11 refers to the storage unit 13 and stores the region information associated with the acquired wireless device information (M01). (H1, H2, S, R1, R2, R3) are acquired. Further, the control unit 11 refers to the storage unit 13 and acquires the location information (E) stored in association with the acquired reading device information (2c). The eyelid determination unit 11d determines whether or not the location information acquired by the control unit 11 is included in the area information acquired by the control unit 11. Here, since the location information is not included in the region information, the control unit 11 operates the notification unit 14. And the alerting | reporting part 14 alert | reports that the to-be-monitored person carrying the IC tag 1 of the radio | wireless machine number M01 is hesitating. Further, the current date and time acquisition unit 11e acquires the current date and time information (7/23 22:00), and the control unit 11 associates the acquired wireless device information (M01) with the current date and time information (7/23 22:00). And stored in the storage unit 13 as history information. Thereafter, the supervisor who has confirmed the notification goes to the supervised person who carries the IC tag 1 with the radio number M01 in the elevator E, and takes the supervised person back to the room R1.

  When the current time is 0:00, the counting unit 11a totals the counting frequency information for each IC tag 1 for 24 hours (from 7/23 0:00 to 7/24 0:00). Since the aggregation frequency information of the IC tag 1 of the radio number M01 is 5 and is higher than the predetermined frequency information 4, the area setting unit 11 c refers to the storage unit 13 and aggregates the aggregation frequency by the aggregation unit 11 a. The region corresponding to the region information stored in association with the wireless device information (M01) corresponding to the information is rewritten to a narrow region (only R1) and stored in the storage unit 13.

  Thereafter, when the monitored person carrying the IC tag 1 with the wireless device number M01 exits the room R1 to the corridor H1, the reading device 2a installed in the corridor H1 reads the wireless device information (M01). The reading device 2a that has read the wireless device information outputs the read wireless device information (M01) and its own reading device information (2a) to the notification device 10.

  When the I / F unit 12 of the notification device 10 inputs the wireless device information and the reading device information, the control unit 11 refers to the storage unit 13 and stores the region information associated with the acquired wireless device information (M01). (R1 only) is acquired. Further, the control unit 11 refers to the storage unit 13 and acquires the location information (H1) stored in association with the acquired reading device information (2a). The eyelid determination unit 11d determines whether or not the location information acquired by the control unit 11 is included in the area information acquired by the control unit 11. Here, since the location information is not included in the region information, the control unit 11 operates the notification unit 14. And the alerting | reporting part 14 alert | reports that the to-be-monitored person carrying the IC tag 1 of the radio | wireless machine number M01 is hesitating. Further, the current date and time acquisition unit 11e acquires the current date and time information, and the control unit 11 associates the acquired wireless device information (M01) with the current date and time information and stores them in the storage unit 13 as history information. Thereafter, the monitor who has confirmed the notification goes to the monitored person carrying the IC tag 1 with the radio number M01 in the hallway H1, and brings the monitored person back to the room R1. As described above, when the movable area is set narrow for the person carrying the IC tag 1 with the radio number M01, the notification device 10 can be obtained only by exiting from the room R2 to the hallway H1. , The supervisor can be informed that he or she is hesitating before coming to the elevator E.

  As described above in detail, in the wrinkle detection system according to the present embodiment, the IC tag 1 is carried by the person to be monitored, and the reading devices 2 that read the radio information from the IC tag 1 are respectively installed at predetermined locations in the facility. To do. Notification is made when the location information of the reading device 2 that has read radio information from the IC tag 1 carried by the monitored person is not included in the area information stored in the storage unit 13 in association with the radio information. The device 10 notifies that the monitored person has left the movable area and stores the history. When the frequency corresponding to the total frequency information aggregated from the history at a predetermined timing is lower than the predetermined frequency, the notification device 10 corresponds to the area information stored in association with the corresponding wireless device information. Is set to a wide area, and when the frequency is higher than a predetermined frequency, the area corresponding to the area information stored in association with the corresponding wireless device information is set to a narrow area.

  As a result, it is less likely that the person goes out of the movable area, and even if the person to be monitored who has a low possibility of hesitation moves, notification due to coming out of the movable area is reduced. Therefore, it is possible to reduce the burden on the monitored person as much as possible to the monitored person who has a low possibility of hesitation. In addition, if the person to be monitored who is likely to get angry often moves out of the movable area, the user is notified that the person has moved out of the movable area. Therefore, a person who is highly likely to hesitate can be monitored as closely as possible.

  In the above-described embodiment, when the frequency corresponding to the aggregation frequency information aggregated by the aggregation unit 11a is compared with the frequency predetermined by the monitor or the like, the frequency determination unit 11b is the same as the predetermined frequency. Although the thing is used, it is not limited to this. For example, the frequency determination unit 11b uses a different frequency as the predetermined frequency when comparing the frequency corresponding to the aggregation frequency information aggregated by the aggregation unit 11a with the frequency predetermined by the monitor or the like. Anyway. In this case, when setting the area widely, it is determined whether or not the frequency corresponding to the aggregation frequency information is lower than the predetermined frequency by using a lower frequency among the predetermined frequencies. On the other hand, when the region is set to be narrow, it is determined whether or not the frequency corresponding to the aggregation frequency information is higher than the predetermined frequency by using a higher frequency among the predetermined frequencies.

  In the above-described embodiment, when the frequency corresponding to the aggregation frequency information aggregated by the aggregation unit 11a is compared with the frequency predetermined by the monitor or the like, the same frequency is used as the predetermined frequency. Although the thing is used, it is not limited to this. For example, the predetermined frequency may be varied for each person to be monitored (in other words, for each IC tag 1).

  In the above-described embodiment, the control unit 11 periodically operates the counting unit 11a at a predetermined timing, but is not limited thereto. For example, when the control unit 11 stores the history information in the storage unit 13, the totaling unit 11a may be operated, or a supervisor or the like may manually execute the totaling unit 11a.

  In addition, the configuration, processing procedure, contents, and the like of the wrinkle detection system can be variously modified and implemented without departing from the gist of the present invention. Moreover, various inventions can be formed by combining a plurality of constituent elements disclosed in the embodiment. For example, you may make it delete a some component from all the components shown by embodiment. Furthermore, you may make it combine the component covering different embodiment suitably.
