Description

Monitored person monitoring support system and monitored person monitoring support method

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 rush of the super-aging society, techniques for complementing operations such as the nursing industry and the nursing care industry have been researched and developed, and are disclosed, for example, in Patent Literatures 1 to 3.

The 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 position on the coordinate of the partial image, and the color image represented by the partial image. The height of the human body is reduced by comparing the height information included in the size information with the height information included in the size information acquired in the past based on the size information indicating the size of the human body A height detection unit that detects whether or not there is an appearance feature amount extraction unit that extracts an appearance feature amount based on the appearance of the human body image when the height decreases, and the appearance feature amount When it is determined that the human body is in the fallen state or not based on the result of referring to the first appearance dictionary based on the above, and when it is discriminated that the human body is in the fallen state, the position coordinates The moving distance of the partial image included in the human body image is calculated based on the information and the position coordinate information acquired in the past, and the moving distance is compared with a threshold, and the human body is compared based on the comparison result. And a movement distance detection unit that detects whether the movement distance of the partial image representing 少ない is smaller than the threshold and detects that the human body included in the human body image falls when the movement distance is small. .

A wheelchair equipped with a seating 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 the control center. It has a seating sensor that detects that it is

The call system disclosed in Patent Document 3 includes a floor detection sensor for detecting an object present on a floor near a bed used by the monitored person, and the monitored person on the floor near the bed. A human body detection sensor for detecting an object in the vicinity of the bed so as to detect the person to be monitored when standing up, and not to detect the person to be monitored when the person to be monitored falls from the bed A notification device for notifying that the person has left the bed, and storage of notification reason information indicating the calling reason by distinguishing that the person to be monitored has moved away from the bed and that the person to be monitored has fallen from the bed Storage device, a timer unit for measuring time, and when the floor detection sensor detects an object, the notification device and the timer unit are operated, and the time measured by the timer unit is In the case where the human body detection sensor detects an object before reaching the time, notification reason information indicating that the monitored person has moved away from the bed is stored in the storage device, and the timer unit measures A control unit for storing, in the storage device, notification reason information indicating that the monitored person has fallen from the bed when the human body detection sensor does not detect an object even if the time reaches a predetermined time A device. The floor detection sensor 1 is configured by an infrared sensor or the like, and when the monitored person using the bed tries to leave the bed, the monitored person's foot falls while the monitored person falls from the bed. It is installed in the position which can detect a to-be-monitored person's body etc. (the [0015] paragraph etc. of the said patent document 3). The human body detection sensor 2 is configured by an infrared sensor or the like, and the body of the person to be monitored when the person using the bed stands on the floor near the bed where the floor detection sensor 1 is installed. A position where it can detect (for example, the head of the person being monitored) and can not detect the person's body when the person using the bed falls from the bed (Eg, paragraph [0018] of Patent Document 3). Therefore, in the call system disclosed in Patent Document 3, the person to be monitored can be separated from the bed by making the arrangement height of the infrared sensor as the floor detection sensor different from the arrangement height of the infrared sensor as the human body detection sensor. It distinguishes having moved away and having said to-be-monitored person falling from a bed.

By the way, for example, when a person to be monitored such as a person to be cared or a person to be cared over falls, for example, a person to be monitored such as a nurse or carer receives notification from the system such as toppling etc. Take measures such as visiting the person to be monitored who has been notified. However, if the notification is a false alarm that is determined by the system as a fall or the like that is not a fall of the monitored person, the supervisor's action is wasted and the labor is lost. turn into. On the other hand, if the system fails to detect the state of the fall or the like and a failure is not generated, the fall or the like is left unchecked, which may lead to a more serious situation. There is sex. Therefore, it is desirable that errors such as false alarms and false alarms are further suppressed and reported more appropriately.

When a fall is detected based on an image as in the fall detection device disclosed in Patent Document 1, for example, a state in which a fall falls on a buttock and a state in which a chair sits down and leans or leans forward Are difficult to distinguish because they look similar on the image. Also, for example, the state of sitting on a chair or a wheelchair and the state of falling off from the chair or wheelchair or the like look similar on an image, so it is difficult to distinguish. For this reason, there is a possibility that a false alarm may occur. In particular, in order to prevent a failure from being reported, it is necessary to report all such difficult-to-understand cases, which increases the number of false alarms.

Also, due to the positional relationship between the bed position and the sensor placement position, the positional relationship in which the monitored person, the monitored person, and the bed overlap when viewed from the sensors when the observer works on the monitored person on the bed In some cases, it may be difficult to determine from the image whether the monitored person has been transferred from bed to a wheelchair, sleeping as it is, or it may be difficult to determine whether the monitored person sleeps on the bed after leaving the observer. There is also the possibility of an erroneous decision.

The wheelchair with a seating sensor disclosed in the patent document 2 only reports the current position of the wheelchair and the presence or absence of seating (the paragraph [0012] of the patent document 2 and the like). Therefore, when the wheelchair with a seating sensor disclosed in Patent Document 2 is not seated, the wheelchair is not seated because it has moved from the wheelchair to another place, or is seated because it has fallen from the wheelchair or the like. It is not possible to distinguish whether it is not or not, so it is not possible to detect a fall or the like. For this reason, if it is determined that the seat falls down and the like when the seat sensor is not seated and a notification is issued, false alarms frequently occur.

Since the call system disclosed in the patent document 3 determines the fall of the person to be monitored by infrared sensors with different arrangement positions, for example, when the user is not in a standing position such as squatting to pick up a falling object, etc. In this case, it is determined that everything has fallen and there is a possibility that false alarms may occur frequently.

More specifically, the plurality of sensor devices SUa-1 to SUa-4, the management server SVa, the fixed terminal SPa, and the private branch exchange CX are connected to the concentrator LS, and the plurality of mobile terminals TAa-1 and TAa-2 are connected. Are connected to the concentrator LS via the access point AP. Then, the network NW constructs a so-called intranet by using an internet protocol group such as a transmission control protocol (TCP) and an internet protocol (IP).

The private branch exchange (line switching unit) CX is connected to the network NW, performs extension telephone control such as call origination, call reception, and telephone call between the portable terminal devices TAa, and implements the extension telephone of the portable terminal devices TAa, For example, it is connected to an outside telephone TL such as a fixed telephone or a mobile telephone through a public telephone network PN such as a fixed telephone network or a mobile telephone network, for example, to make, receive, and make calls between the outside telephone TL and the mobile terminal device TAa. , Etc. to control the outside line telephone and carry out the outside line telephone 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 disposed at an appropriate place according to the monitored person Ob. The monitored person (watching target person) Ob is, for example, a person who needs nursing due to illness or injury, a person who needs care due to a decrease in physical ability or the like, or a single person living alone. In particular, from the viewpoint of enabling early detection and coping, the person to be monitored Ob is a person who needs the detection when a predetermined adverse event such as an abnormal condition occurs in the person. preferable. For this reason, the person-to-be-monitored monitoring support system MSa is suitably disposed in buildings such as hospitals, welfare facilities for the elderly and dwelling units according to the type of the person to be monitored Ob. In the example shown in FIG. 1, the monitored person monitoring support system MSa is disposed in a building of a care facility provided with a plurality of living 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 and the like for communicating with other devices SVa, SPa, TAa via the network NW, detects a predetermined action in the monitored person Ob, and sends the detection result to the management server device SVa together with an image. It is an apparatus to transmit. Then, in the present embodiment, when the sensor device SUa detects the seating of the person to be monitored Ob and transmits the detection result to the management server device SVa, the detection result is a seating detection result of the seating detection unit. Process with different processing methods based on For example, as illustrated in FIG. 2, such a sensor device SUa includes an imaging unit 11, a seating detection unit 12, a sensor control processing unit (SU control processing unit) 13a, and a sensor communication interface unit (SU communication An IF unit 14 and a sensor storage unit (SU storage unit) 15 are provided.

The imaging unit 11 is connected to the SU control processing unit 13a, and according to the control of the SU control processing unit 13a, an image (image) showing the shape of the person to be measured Ob in order to detect a predetermined action on the person to be monitored Ob. Data) is generated. The imaging unit 11 is arranged to be able to monitor the space (location space; room (room) RM of the arrangement location in the example shown in FIG. 1) where the monitored person Ob who is the monitoring target to be monitored is scheduled to be located The location space is imaged from above as an imaging target, an image (image data) in which the imaging target is viewed is generated, and an image (target image) of the imaging target is output to the SU control processing unit 13a. Preferably, the imaging unit 11 may position the head of the monitored person Ob in the bedding (for example, a bed or the like) in which the monitored person Ob lays, since the probability of capturing the entire monitored object Ob of the monitored object is high. It arrange | positions so that an imaging target can be imaged from immediately on the head preset position (usually the arrangement | positioning position of a pillow) of the preset preset head plan. The sensor unit SU uses the imaging unit 11 to obtain an image of the person to be monitored Ob, which is taken from above the person to be monitored Ob, preferably an image of the person to be monitored Ob, which is taken from directly above the planned head position.

Such an imaging unit 11 may be a device that generates an image of visible light, but in the present embodiment, it is a device that generates an infrared image so that the monitored person Ob can be monitored even in a relatively dark state. . In the present embodiment, for example, in the present embodiment, such an imaging unit 11 forms an imaging optical system that forms an optical image of infrared in an imaging target on a predetermined imaging surface, and makes the light receiving surface coincide with the imaging surface.

In the present 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)) having an angle of view capable of imaging the entire room RM provided. . Alternatively, the imaging unit 11 may be a thermographic camera that generates a thermal distribution image of an imaging target.

The seating detection unit 12 is connected to the SU control processing unit 13a, and is arranged (for example, a chair, a wheelchair, and a toilet facility) where seating of the monitored person Ob is scheduled (estimated), and seating of the monitored person Ob Is a device that detects The seating detection unit 12 outputs the seating detection result to the SU control processing unit 13a. The seating detection unit 12 determines, for example, the presence or absence of seating in the monitored person Ob at predetermined time intervals (sampling intervals), and for each determination, "seating" or "no seating" is determined according to the determination. It may be output to the management server device SVa as a seating detection result. Further, for example, the seating detection unit 12 determines the presence or absence of seating in the monitored person Ob at a predetermined time interval (sampling interval), and detects “seating” only when the seating of the monitored person Ob is detected. "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 the absence of seating by not inputting the presence of seating. The seating detection unit 12 may be connected to the SU control processing unit 13a by wire, and may be connected to the SU control processing unit 13a by short distance wireless communication such as Bluetooth (registered trademark) standard, for example.

Such a seating detection unit 12 includes, for example, a contact-type seating sensor such as a pressure sensor or a vibration sensor. The pressure sensor is disposed, for example, on a seating surface of a chair, a wheelchair, a toilet facility, or the like so as to detect pressurization (pressure increase) due to the seating of the monitored person Ob. The vibration sensor is disposed, for example, on a seating surface of a chair, a wheelchair, a toilet facility or the like so as to detect a vibration caused by the seating 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 disposed so as to detect heat (infrared radiation) emitted from the monitored person Ob in, for example, an arrangement area of a chair and a toilet facility.

The SU communication IF unit 14 is a communication circuit which is connected to the SU control processing unit 13a and performs communication according to the control of the SU control processing unit 13a. The SU communication IF unit 14 generates a communication signal containing the data to be transferred, which is input from the SU control processing unit 13a, according to the communication protocol used in the network NW of the person-to-be-monitored monitoring support system MSa The communication signal is transmitted to the other devices SVa, SPa, TAa via the network NW. The SU communication IF unit 14 receives communication signals from the other devices SVa, SPa, TAa via the network NW, extracts data from the received communication signals, and the SU control processing unit 13a can process the extracted data. It converts into data of the following format and outputs it to the SU control processing unit 13a. The SU communication IF unit 14 is configured to include, for example, a communication interface circuit according to the IEEE 802.11 standard or the like.

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

The SU control processing unit 13a controls each of the

units

11, 12, 14, 15 of the sensor device SUa according to the function of each of the

units

11, 12, 14, 15, and sets a predetermined set of observers 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, when the SU control processing unit 13a detects the seating of the person to be monitored Ob and transmits the detection result to the management server device SVa, the seating of the seating detection unit 12 is the detection result. Process with different processing methods based on detection results. The SU control processing unit 13a includes, for example, a central processing unit (CPU) and peripheral circuits thereof. 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.

respective units

11, 12, 14, 15, and controls the entire control of the sensor unit SUa.

The action detection processing unit 132 detects a predetermined action set in advance in the monitored person Ob. More specifically, in the present embodiment, the predetermined action is, for example, leaving the bed when the monitored person Ob leaves the bedding, falling down when the monitored person Ob falls from the bedding, and falling down the monitored person Ob. There are three actions of falling. The action detection processing unit 132 detects, for example, bed departure, falling, and falling in 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, a first threshold Th1 for determining the presence or absence of bed leaving, and a second threshold Th2 for determining the presence or absence of falling or falling are one of the various predetermined data. Are stored in advance in the SU storage unit 15 as one. For the location area of the bedding BD, the setting screen shown in FIG. 3 is displayed on the terminal devices SPa and TAa, for example, on the fixed terminal apparatus SPa, and four vertex positions in the location area of the bedding BD are displayed on the displayed setting screen. Coordinates on the target image are input and stored in the sensor unit SUa from the fixed terminal unit SPa via the management server unit SVa. On the setting screen, the target image generated by the imaging unit 11 is displayed on the fixed terminal apparatus SPa via the management server apparatus SVa. In the case where the seating detection unit 12 is a non-contact seating sensor, four vertex positions (coordinates on the target image) in the arrangement area, such as a chair and a toilet facility, are further determined from the setting screen. Is input from the fixed terminal SPa and stored in the sensor unit SUa via the management server SVa. In the present embodiment, as shown in FIG. 4B, the presence or absence of leaving of the bed is a region (overlap region out of the location region of the bedding BD in the person region HA extracted from the target image, as shown in FIG. ) It is determined based on the size of Hout. Therefore, the first threshold Th1 is a value for identifying the size of the protruding area before leaving the bed and the size of the protruding area 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 the time change of the position and the size of the monitored person Ob in the head region HD. For this reason, the second threshold value Th2 is used to identify whether the size of the head area HD in the standing position or the size of the head area HD in the sitting position (or lying position). The value is appropriately set in advance from a plurality of samples.

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

The detection result processing unit 133 a 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. More specifically, in the present embodiment, in the first processing method, the detection result processing unit 133a causes the terminal devices SPa and TAa to display the detection result when the seating detection result is not the seating of the monitored person Ob. It processes, and when the said seating detection result is seating of the to-be-monitored person Ob, the said sensing result is processed by the 2nd processing method which is not displayed on terminal device SPa and TAa. More specifically, the second processing method is a processing method which does not transmit the detection result to the management server SVa. That is, in the first processing method, as described above, when the action detection processing unit 132 detects the predetermined action, the detection result processing unit 133a detects that the seating detection result is not the seating of the monitored person Ob. The SU communication IF unit 14 manages a communication signal (first action detection notification communication signal) for notifying (notifying) the detection, which contains information indicating the content of a predetermined action in the detected monitored person Ob. It transmits to the server apparatus SVa. The first action detection notification communication signal includes, for example, the sensor ID of the own machine, information indicating the content of a predetermined action in the detected monitored person Ob (in the embodiment, any one of bed leaving, falling and falling) And the target image used for the detection of the predetermined action. In the second processing method, as described above, even if the action detection processing unit 132 detects the predetermined action, the detection result processing unit 133a detects that the seating detection result indicates that the monitored person Ob is seated. The first action detection notification communication signal is not transmitted. In addition, the transmission process of the first action detection notification communication signal may be executed by the action detection processing unit 132, and in this case, the action detection processing unit when the seating detection result is not the seating of the monitored person Ob. If the process of transmitting the first action detection notification communication signal by 132 is permitted, and the seating detection result indicates that the monitored person Ob is seated, the first action detection notification communication signal by the action detection processing unit 132 Prohibits transmission processing.

More specifically, when the SV monitoring processor 222 receives the first activity detection notification communication signal from the sensor device SUa, the SV monitoring processor 222 monitors the monitored person Ob accommodated in the received first activity detection notification communication signal. Are stored (recorded) in the SV storage unit 23. Then, the SV monitoring processing unit 222 is accommodated in the received first action detection notification communication signal to notify (re-notify, re-notify, transmit) the detection result notified by the first action detection notification communication signal.

Next, the operation of this embodiment will be described. FIG. 7 is a flowchart showing the operation of the sensor device. FIG. 8 is a flowchart showing an operation in the action detection process shown in FIG. FIG. 9 is a flow chart showing the operation in the fall detection processing shown in FIG. FIG. 10 is a flowchart showing an operation in the process of detecting bed departure shown in FIG. FIG. 11 is a flowchart showing an operation in the process of 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 in the first embodiment. FIG. 13 is a diagram showing an example of a monitoring information display screen displayed on the mobile terminal device in the monitored person monitoring support system in the first embodiment.

In the person-to-be-monitored person monitoring support system MSa configured as described above, each of the devices SUa, SVa, SPa, and TAa performs initialization of necessary parts when the power is turned on, and starts its operation. In the sensor device SUa, an SU control unit 131, an action detection processing unit 132, and a detection result processing unit 133a are functionally configured in the SU control processing unit 13a by execution of the control processing program. In the management server SVa, an SV control unit 221 and an SV monitoring processing unit 222 are functionally configured in the SV control processing unit 22 by execution of the control processing program. Then, the sensor device SUa detects a predetermined operation in 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) for 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 device SUa causes the action detection processing unit 132 of the SU control processing unit 13a to extract a person area HA in order to detect a predetermined action in the monitored person Ob based on the target image. In the present embodiment, although the person area HA suffices to detect bed departure, but the head area HD is used to detect falling or falling, etc., the sensor apparatus SUa further causes the behavior detection processing unit 132 to A head region HD is extracted from the extracted person region HA (S2).

Next, the sensor device SUa causes the behavior detection processing unit 132 to execute a process of detecting a behavior to detect a predetermined behavior in the monitored person Ob based on the person area HA and the head area HD extracted in the process S2. (S3).

More specifically, in the action detection process S3 of this action, the action detection processing unit 132 executes a fall fall detection process S31 for detecting a fall or a fall in FIG. The process S32 is executed.

More specifically, in the detection process S31 of this fall, the action detection processing unit 132 first determines whether or not the conditions of the fall and the fall are satisfied in FIG. 9 (S311). More specifically, the action detection processing unit 132 first performs the process S2 when the position of the head area HD extracted in the process S2 changes from the area where the bedding BD is located to the time when the area of the bedding BD is outside the area If the size of the head region HD extracted in the above is equal to or less than the second threshold value Th2, it is determined that a fall has occurred (Yes), the fall is detected (S312), and the process S31 is ended. Then, in the action detection processing unit 132, the position of the head area HD extracted in the process S2 is in the living room RM excluding the area where the bedding BD is located, and the size of the head area HD extracted in the process S2 is If the second threshold Th2 or less, it is determined that a fall (Yes), detects the fall (S312), and ends the process S31. On the other hand, when excluding these, the action detection processing unit 132 determines that neither falling nor falling has occurred (No), and ends the present process S31.

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

In the process S322, the behavior detection processing unit 132 determines whether or not the condition for bed departure is satisfied. More specifically, the behavior detection processing unit 132 first determines that the user has left the bed when the ratio of the protruding area HAout to the human area HA exceeds the first threshold Th1 ((HAout / HA)> Th1)) (Yes ), The bed leaving is detected (S323), the state of the person to be monitored Ob is updated (changed) after bed leaving (S324, the state variable 「“ after bed leaving ”), and the process S32 is ended. On the other hand, in the case of excluding this, the behavior detection processing unit 132 determines that it is not bed departure (No), and ends the present process S32. In the case where wake-up is detected from the lying condition of the person to be monitored Ob or arrival of the person to be monitored Ob is detected, the state of the person to be monitored Ob is updated (changed) before leaving the bed (the state Variable 「" Before getting out of bed ").

As described above, when the action detection process S3 is performed, the sensor device SUa causes the detection result processing unit S3 of the SU control processing unit 13a to detect the detection result by the action detection process S3, and the seating detection result of the seating detection unit 12 The processing of detection results to be processed by different processing methods is executed based on (S4), and the present processing is terminated.

More specifically, in FIG. 11, the detection result processing unit 133a first obtains 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 the determination, if the seating detection result acquired in the processing S41 indicates that the monitored person Ob is seated (Yes), the processing S43 is executed, and the processing S4 is ended. On the other hand, as a result of the determination, when the seating detection result acquired in the processing S41 indicates no seating of the monitored person Ob (No), the processing S44 and the processing S45 are sequentially executed, and the processing S4 is performed. finish.

In the process S43, the detection result processing unit 133a cancels and deletes the detection result detected in the process S3 in order to process the detection result by the second processing method in which the terminal devices SPa and TAa are not displayed. Therefore, the detection result processing unit 133a does not transmit the detection result detected in the process S3 to the management server device SVa. If the seating detection unit 12 detects the seating of the monitored person Ob when the sensor device SUa detects the predetermined action, the monitored person Ob is seated, and so the bed leaving, falling, falling, etc. The detection result of the predetermined action has a high possibility of false detection, and the detection result can be corrected by the seating detection result of the seating detection unit 12. In particular, when the predetermined action is detected based on the image, it is considered that the seating detection result is higher in detection reliability than the detection result by the image, so the detection result is more determined by the seating detection result. Correctable.

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

As the sensor apparatus SUa operates as described above, in the monitored person monitoring support system MSa, for example, as shown in FIG. 12, the behavior detection processing unit 132 detects a predetermined behavior and the seating detection unit 12 When the absence of seating is detected (C1), the sensor device SUa transmits a first action detection notification communication signal to the management server device SVa (C2). When the management server device SVa receives the first activity detection notification communication signal, it stores the monitoring information contained in the received first activity detection notification communication signal (C3), and the received first activity detection notification communication A second action detection notification communication signal based on the signal is transmitted to the predetermined terminal devices SPa and TAa (C4). Then, when receiving the second activity detection notification communication signal, the terminal devices SPa and TAa display the monitoring information contained in the received second activity 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 portable terminal device TAa. The monitoring information display screen 51 displays the room name of the room RM in which a predetermined action is detected, the name of the detected predetermined action, and a target image when the predetermined action is detected. In order to display the room name of the room RM displayed on the monitoring information display screen 51, a sensor ID and a sensor apparatus SUa having the sensor ID are provided in the portable terminal apparatus TAa. The correspondence with the name is stored in advance. From this correspondence relationship, the mobile terminal device TAa searches the room name of the room RM corresponding to the sensor ID contained in the second activity detection notification communication signal, and displays the room name according to the search result on the monitoring information display screen 51. Do. Then, the mobile 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. Thus, the monitor (user) who handles the mobile terminal device TAa notifies the monitored person Ob who is present in the room RM of the room name of the predetermined action reported by referring to the monitoring information display screen 51. It can be recognized and its appearance can be recognized from the target image.

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

As described above, the target person monitoring support system MSa in the first embodiment and the target person monitoring support method implemented in the processing process the detection result based on the seating detection result. It is possible to increase the credibility of the result and thus to be notified more appropriately.

When the seating detection result is not the seating of the monitored person Ob, the monitored person monitoring support system MSa and the monitored person monitoring support method cause the terminal devices SPa and TAa to display the detection results, and the seating detection result is Since the detection results are not displayed on the terminal devices SPa and TAa when the monitored person Ob is seated, the reliability of the detection results can be enhanced, and therefore, notification can be issued more appropriately.

Depending on the nursing level and the care level, when the monitored person Ob leaves the floor, the monitoring person receives the notification, for the purpose of assisting with, for example, excretion, washing and getting ready, for example, for the purpose of preventing the fall. It goes to the place of person Ob. When the monitored subject Ob falls or falls, the monitoring subject visits the monitored subject Ob upon receiving the notification for the purpose of rescue of the monitored subject Ob. In the above-mentioned person-to-be-monitored person monitoring support system MSa and the person-to-be-monitored person monitoring support method, the predetermined action includes at least one of “bedding”, “falling” and “falling”, so This reduces unnecessary work due to false alarms and can effectively reduce the burden on the observer.

In the above 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 provided in the terminal devices SPa and TAa. It may be done.

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

When the management server device SVa includes the detection result processing unit, first, the detection result processing unit 133a is omitted from the sensor device SUa, and the action detection processing unit 132 replaces the first detection result notification communication signal instead of the detection result processing unit 133a. It transmits to the management server apparatus SVa. In this case, in the first detection result notification communication signal, the sensor ID of the own device, information indicating the content of the predetermined action in the detected monitored person Ob (in this embodiment, among the bed leaving, falling and falling) Not only is the target image used to detect the predetermined action and the target image stored, but also the seating detection result (in the present embodiment, either seating presence or no seating) is also included Ru. The management server SVa not only functionally includes the SV control unit 221 and the SV monitoring processing unit 222 in the SV control processing unit 22 but also functionally includes 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 a predetermined action in the monitored person Ob. Based on the seating detection result of the seating detection unit 12 contained in the first detection result notification communication signal, processing is performed using different processing methods. 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 is not the seating of the monitored person Ob (in the case of no seating). The second processing method does not display the detection result on the terminal devices SPa and TAa when processing is performed by the first processing method and the seating detection result indicates that the monitored person Ob is seated (seating is present) Do. More specifically, the second processing method is a processing method which does not transmit the detection result to the terminal devices SPa and TAa. That is, in the above, since the SV monitoring processing unit 222 transmits the second activity detection notification communication signal based on the received first activity detection notification communication signal to the predetermined terminal devices SPa and TAa, the detection in the management server SVa The result processing unit permits the SV monitoring processing unit 222 to transmit the second activity detection notification communication signal when the seating detection result is not the seating of the monitored person Ob (in the case of no seating), and the seating is performed. When the detection result indicates that the person to be monitored Ob is seated (when there is seating), the SV monitoring processing unit 222 is prohibited from transmitting the second activity detection notification communication signal.

In the person-to-be-monitored monitoring support system MSa in the first modified embodiment, when the action detection processing unit 132 detects a predetermined action and the seating detection unit 12 detects no seating, the first detection result notification Each processing of the above-described processing C1 to processing C5 shown in FIG. 12 is executed except that the seating detection result is accommodated in the communication signal.

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 device SUa further determines that seating is detected as the seating detection result. The received first action detection notification communication signal is transmitted to the management server device SVa (C12). When the management server device SVa receives the first action detection notification communication signal, the management server device SVa stores the monitoring information contained in the received first action detection notification communication signal (C13), and the seating detection result indicates that seating is present. Therefore, transmission processing of 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 activity detection notification communication signal based on the first activity detection notification communication signal to the predetermined terminal devices SPa and TAa, and the terminal devices SPa and TAa transmit the second activity detection notification communication signal. The monitor information display screen 51 is not displayed based on the above. As a result, the person-to-be-monitored support system MSa can issue a notification more appropriately. Further, 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 supervisor (user) checks the storage content of the management server device SVa. The fact that the false notification has been stopped by the management server SVa can be verified.

In the above description, the detection result processing unit in the management server device SVa transmits the second behavior detection notification communication signal to the SV monitoring processing unit 222 according to the absence or the presence of the seating detection result. Although permitted or prohibited, the detection result processing unit in the management server device SVa executes transmission processing of the second action detection notification communication signal instead of the SV monitoring processing unit 222 as in the detection result processing unit 133a described above. You may. In this case, as in the detection result processing unit 133a described above, the detection result processing unit in the management server device SVa transmits the second activity detection notification communication signal according to the absence or presence of the seating detection result. Run or not run.

In the case where the terminal devices SPa and TAa include the detection result processing unit, the detection result processing unit 133a is omitted from the sensor unit SUa as in the case where the management server SVa described above includes the detection result processing unit. 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 is information contained in the received first action detection notification communication signal, the sensor ID, and information indicating the content of a predetermined action in the monitored person Ob (in this embodiment, Not only accommodating the bed leaving, falling or falling), and accommodating the target image in the second detection result notification communication signal, and further, the seating detection contained in the received first action detection notification communication signal The results (in the present embodiment, either with or without seating) are also accommodated. The terminal devices SPa and TAa include a detection result processing unit. The detection result processing unit in each of the terminal devices SPa and TAa includes 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 action in the monitored person Ob. Processing is performed with different processing methods 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 unit in the terminal devices SPa and TAa sends the detection results to the terminal devices SPa and TAa when the seating detection result is not the seating of the monitored person Ob (when there is no seating). It processes by the 1st processing method to display, and when the said seating detection result is seating of the said to-be-monitored person Ob (when there is seating), it does not display the said sensing result on the said terminal device SPa and TAa by the 2nd processing method To process. More specifically, the second processing method is a processing method which 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 is not seating of the monitored person Ob (without seating). If the seating detection result indicates that the monitored person Ob is seated (seating is present), the detection result is not displayed.

In the monitored person monitoring support system MSa in the second modified embodiment, when the action detection processing unit 132 detects a predetermined action and the seating detection unit 12 detects no seating, the first and second monitored Each of the processes C1 to C5 shown in FIG. 12 is executed except that the seating detection result is accommodated in each of the detection result notification communication signals.

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 device SUa further determines seating presence as the seating detection result. The received first action detection notification communication signal is transmitted to the management server device SVa (C22). When the management server device SVa receives the first action detection notification communication signal, the management server device SVa stores the monitoring information contained in the received first action detection notification communication signal (C23), and the seating detection result is further added as the seating detection result. The second activity detection notification communication signal received is transmitted to the predetermined terminal devices SPa and TAa (C24). When the terminal devices SPa and TAa receive the second activity detection notification communication signal, the seating detection result indicates that there is a seat, and thus the monitoring information display screen 51 is displayed based on the received second activity detection notification communication signal. do not do. As a result, the person-to-be-monitored support system MSa can issue a notification more appropriately. Further, 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) checks the storage content of the management server device SVa. The terminal devices SPa and TAa can verify the fact that false alarm has been stopped.

Next, another embodiment will be described.

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 view 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 in the first embodiment processes the detection result by a different processing method whether to display the detection result on the terminal device based on the seating detection result. However, the monitored result in the second embodiment The person monitoring support system processes the detection result by a different processing method for displaying on the terminal device in different display modes based on the seating detection result.

For example, as shown in FIG. 1, the monitored person monitoring support system MSb according to the second embodiment includes one or more sensor devices SUb (SUb-1 to SUb-4), and the management server device SVa. The fixed terminal apparatus SPb, one or more mobile terminal apparatuses TAb (TAb-1, TAb-2), and a private branch exchange CX are connected communicably 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, and thus 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. 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 according to the second embodiment respectively correspond to the imaging unit 11 and the seating detection unit 12 in the sensor device SUa according to the first embodiment. Since the SU communication IF unit 14 and the SU storage unit 15 are the same, the description thereof is 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 set in advance, and detects the detection result together with an image, with the management server device. It is a circuit for transmitting to SVa. Then, in the present embodiment, when the SU control processing unit 13b detects the seating of the person to be monitored Ob and transmits the detection result to the management server device SVa, the seating of the seating detection unit 12 is the detection result. Process with different processing methods based on 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. Because there is, I omit the explanation.

The detection result processing unit 133 b 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. More specifically, in the present embodiment, the detection result processing unit 133b sends the detection result to the terminal devices SPb and TAb in a predetermined first display mode when the seating detection result is not the seating of the monitored person Ob. The terminal apparatus SPb, TAb is processed by the third processing method to be displayed, and when the seating detection result is the seating of the monitored person Ob, the detection result is displayed in a predetermined second display mode different from the first display mode. It processes by the 4th processing method displayed on. The first and second display modes are display modes indicating the degree of reliability of the detection result, and the second display mode is a display mode indicating that the degree of reliability is lower than the first display mode. is there. More specifically, first, in the present embodiment, the predetermined behavior not only includes bedriding, falling and falling, and further, bedriding suspected of the monitored person Ob being separated from the bedding (monitored person Ob Is suspected of getting away from the bedding), suspicion that the monitored person Ob has fallen from the bedding suspected of falling (believed that the monitored person Ob may have fallen out of the bedding), the monitored person Ob falls There are suspected falls (suspected falls that the monitored person Ob may have fallen). The suspected bed break is a detection result that is less reliable than the bed break. The fall possibility is a detection result that is less reliable than the fall. The suspected fall is a detection result that is less reliable than the fall. In the third processing method, the detection result processing unit 133b determines the detection result as it is and displays the detection result as it is when the seating detection result is not the seating of the monitored person Ob. Display on terminal devices SPb and TAb. That is, in the third processing method, when the action detection processing unit 132 detects the predetermined action, the detection result processing unit 133 b detects the first action when the seating detection result is not the seating of the monitored person Ob. The notification communication signal is transmitted by the SU communication IF unit 14 to the management server device SVa. In the present embodiment, in the first display mode, a predetermined action in the detected 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 doubt detection result and displays a doubt detection result when the seating detection result indicates that the person to be monitored Ob is seated. (2) Display on the terminal devices SPb and TAb in a display mode. In the present embodiment, when the detection result is bed leaving, the detection result processing unit 133b changes the bed leaving to be a bed leaving suspect when the seating detection result is the seating of the person to be monitored Ob. When the detection result is a fall, the detection result processing unit 133b changes the fall into a fall possibility if the seating detection result indicates that the person to be monitored Ob is seated. In the case where the detection result is falling, the detection result processing unit 133b changes the falling into a fall possibility if the seating detection result indicates that the person to be monitored Ob is seated. That is, in the fourth processing method, when the action detection processing unit 132 detects the predetermined action, the detection result processing unit 133 b detects the first action when the seating detection result indicates that the monitored person Ob is seated. The notification communication signal is transmitted by the SU communication IF unit 14 to the management server device SVa. In the second display mode, a predetermined action in the detected monitored person Ob is displayed on, for example, monitoring information display screens 52 and 53 shown in FIG. 18 described later, and the monitoring information display screens 52 and 53 are The display mode different from the first display mode indicates that the detection result is relatively low in reliability. The first action detection notification communication signal includes, for example, the sensor ID of the own device, information indicating the content of a predetermined action in the detected monitored person Ob (in this embodiment, bed departure, fall, fall, suspicion, fall A target image used for detection of any of doubt and suspicion of falling) and the predetermined action is stored. In the third processing method, any one of bed leaving, falling and falling is accommodated in the first activity detection notification communication signal, and in the fourth processing method, the first activity detection notification communication signal is suspected of leaving the floor , Or a fall or suspicion of fall is accommodated.

The fixed terminal apparatus SPb and the portable terminal apparatus TAb respectively detect the second activity detection notification communication signal received from the management server apparatus SVa as the doubt detection result (in the present embodiment, any of the bed departure, the fall suspect and the fall suspect). Fixed in the monitored person monitoring support system MSa of the first embodiment except that the detection result of the suspicion is displayed in a second display mode in which the suspicion detection result is displayed when? The terminal device SPa and the mobile terminal device TAa are the same as the terminal device SPa and the mobile terminal device TAa.

In the monitored person monitoring support system MSb according to the second embodiment, the sensor unit SUb is shown in FIG. 7 every frame or every several frames as in the sensor unit SUa according to the first embodiment. The image acquisition process S1 described above, the extraction process S2 of the person area etc. described above, the detection process S3 of the predetermined action described above, and the process S5 of the detection result executed as described later. By doing this, a predetermined operation in the monitored person Ob is detected.

In processing S5 of a detection result in this 2nd embodiment, in Drawing 16, detection result treating part 133b acquires a seating detection result of seating detection part 12 first (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, when the seating detection result acquired in the processing S51 indicates that the monitored person Ob is seated (Yes), the processing S53 is performed, and then the processing S55 is performed, and the processing S5 is ended. Do. On the other hand, if it is determined that the seating detection result acquired in the processing S51 indicates that the monitored person Ob is not seated (No), the processing S55 is performed after the processing S54, and the main processing S5 Finish.

In the processing S53, in order to process the detection result in the fourth processing method for displaying the terminal apparatus SPb and TAb in a second display mode that displays that the detection result is relatively low in reliability. The detection result processing unit 133b changes the detection result detected in the processing S3 to a detection result of doubt. That is, when the detection result of process S3 is bed leaving, falling, and fall, respectively, the detection result processing unit 133b changes the bed leaving doubt, the falling suspect, and the falling suspect. If the seating detection unit 12 detects the seating of the person to be monitored Ob when the sensor device SUb detects the predetermined action, the person to be monitored Ob sits on the floor, falling down, falling, etc. The detection result of the predetermined action is lower in reliability than the case where 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 action is detected based on the image, it is considered that the seating detection result is higher in detection reliability than the detection result by the image, so the detection result is more determined by the seating detection result. Correctable.

In the process S54, the detection result processing unit 133b causes the terminal device SPb or TAb to display the detection result in the first display mode that indicates that the detection result is a relatively high detection result of the reliability. In order to process by a method, the detection result detected by process S3 is decided as it is (a final detection result and determination (decision)).

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

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, substantially as in the first embodiment, A second activity detection notification communication signal based on the received first activity detection notification communication signal is transmitted to predetermined terminal devices SPb and TAb. Here, in the second embodiment, the second action detection notification communication signal includes the sensor device SUb because the predetermined behavior includes not only bed break, fall and fall but also bed break, doubt and fall. As information representing the contents of a predetermined action in the monitored person Ob detected in the above, any of leaving, falling, falling, falling, doubting to leave, suspicion of falling and suspicion of falling is accommodated.

When the terminal devices SPb and TAb receive the second activity detection notification communication signal, the terminal devices SPb and TAb display the monitoring information contained in the received second activity detection notification communication signal on the monitoring information display screen. More specifically, in FIG. 17, the terminal devices SPb and TAb determine what the detection result detected by the sensor device SUb is (S61). More specifically, the terminal devices SPb and TAb determine what information representing the content of the predetermined action contained in the received second action detection notification communication signal. As a result of this determination, when the information indicating the content of the predetermined action is any one of bed break, fall and fall (bed break, fall and fall), the terminal devices SPb and TAb select the detection result After the processing S63 of displaying in one display mode is executed, the present processing is ended. On the other hand, as a result of the determination, if the information indicating the content of the predetermined action is any of doubting of bed leaving, suspicion of falling or suspicion of falling (suspecting of bed leaving, suspicion of falling, suspicion of falling), terminal apparatus SPb The TAb ends the present processing after executing the processing S62 of displaying the detection result of the 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 activity detection notification communication signal, for example, on the monitoring information display screen 51 shown in FIG. This monitoring information display screen 51 displays leaving and falling and falling over as a text as it is, so that the detection result is a detection result having a relatively high reliability as compared with the monitoring information display screens 52 and 53 shown in FIG. It represents that there is.

On the other hand, in the process S63, the terminal devices SPb and TAb monitor the monitoring information contained in the received second activity detection notification communication signal, for example, the monitoring information display screen 52 shown in FIG. 18A or the monitoring shown in FIG. It is displayed on the information display screen 53. In the example illustrated in FIG. 18, the monitoring information display screens 52 and 53 are displayed on the mobile terminal device TAb. On the monitoring information display screen 52 shown in FIG. 18A, the room name of the room RM in which the predetermined action is detected, the name of the detected predetermined action, and the exclamation mark (!) Are displayed. In this monitoring information display screen 52, the character attributes (type of font, font size, character color and display density (display luminance)) of each character in the room name of the room RM and each character in the name of the action are displayed. An observer (user) who expresses relatively low reliability such as an exclamation mark (!) By changing the character attribute of each character displayed on the monitoring information display screen 51 of the first display mode. By displaying a specific icon for prompting the user, it is shown that the detection result is a detection result having a relatively low reliability as compared with the monitoring information display screen 51 shown in FIG. Each character displayed on the monitoring information display screen 52 shown in FIG. 18A is displayed with a lighter display density than 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. 18B includes the room name of the room RM where the predetermined action is detected, the name of the detected predetermined action, and the predetermined The target image at the time of detecting the action of is displayed. However, on this monitoring information display screen 53, the display size (resolution) of the target image is further changed by changing the character attribute of each character to the character attribute of each character represented on the monitoring information display screen 51 of the first display mode. As compared with the monitoring information display screen 51 shown in FIG. 13, the detection result indicates that the detection result is a detection result with relatively low reliability. Each character displayed on the monitoring information display screen 53 shown in FIG. 18B is displayed as a character having a smaller number of points than the monitoring information display screen 51 shown in FIG. 13, and the target image is the monitoring information shown in FIG. Compared to the display screen 51, the display screen is displayed in a smaller display size (low resolution). Furthermore, in the monitoring information display screens 52 and 53 shown in FIG. 18, the detection result is relatively less reliable than the monitoring information display screen 51 shown in FIG. 13 even when the text “suspect” is displayed. It represents that it is a result. By thus changing the display mode, the observer (user) can visually recognize the reliability of the detection result.

The monitored person monitoring support system MSb in the second embodiment and the monitored person monitoring support method implemented in this change the display mode of the detection result based on the seating detection result, so from the display mode, The reliability of the detection result based on the seating detection result can be recognized, and accordingly, the notification can be issued 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 according to the absence or the presence of the seating detection result, but instead of or in addition to this, A relatively loud notification sound or a relatively small notification sound may be output. Furthermore, instead of or in addition to these, the terminal devices SPb and TAb may output a notification sound with a relatively long time length or a notification sound with a relatively short time length.

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

For example, since the sensor device SUb detects no seating in the seating detection unit 12, the terminal devices SPb and TAb monitor information stored in the received second activity detection notification communication signal, for example, monitoring information illustrated 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 a notification sound (for example, ringing tone etc.) having a relatively large and long time length. Output On the other hand, since the sensor device SUb has detected the presence of seating by the seating detection unit 12, the terminal devices SPb and TAb monitor the monitoring information contained in the received second behavior detection notification communication signal, for example, monitoring information shown in FIG. 18B. 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 a notification sound with a relatively small and short time length (for example, "pipi" etc. Output).

Next, another embodiment will be described.

Third Embodiment
The monitored person monitoring support system MSa in the first embodiment processes the detection result according to a different processing method as to whether or not to display the detection result on the terminal device based on the seating detection result. The person monitoring support system processes the detection result according to different processing methods as to whether or not the management server device manages the detection result based on the seating detection result.

The monitored person monitoring support system MSc in the third embodiment is, for example, as shown in FIG. 1, one or more sensor devices SUc (SUc-1 to SUc-4), a management server device SVc, The fixed terminal apparatus SPa, one or more portable terminal apparatuses TAa (TAa-1, TAa-2), and a private branch exchange CX are connected communicably via a network NW. The fixed terminal apparatus SPa and the portable terminal apparatus TAa in the monitored person monitoring support system MSc of the third embodiment are respectively connected with the fixed terminal apparatus SPa and the portable terminal apparatus TAa in the monitored person monitoring support system MSa of the first embodiment. The description is omitted because it is similar.

The sensor device SUc in the monitored person monitoring support system MSc of the third embodiment is, for example, as shown in FIG. 2, 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 according to the third embodiment respectively correspond to the imaging unit 11 and the seating detection unit 12 in the sensor device SUa according to the first embodiment. Since the SU communication IF unit 14 and the SU storage unit 15 are the same, the description thereof is omitted.

The SU control processing unit 13c controls each unit of the sensor device SUc according to the function of each unit, detects a predetermined action related to the monitored person Ob set in advance, and detects the detection result together with an image with the management server device. It is a circuit for transmitting to SVc. Then, in the present embodiment, when the SU control processing unit 13c detects the seating of the monitored person Ob and transmits the detection result to the management server device SVc, the seating of the seating detection unit 12 is the detection result. Process with different processing methods based on 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 the same as the SU control unit 131 and the action detection processing unit 132 in the SU control processing unit 13a of the first embodiment, respectively. Because there is, I omit the explanation.

The detection result processing unit 133 c 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. More specifically, in the present embodiment, the fifth processing method causes the detection result processing unit 133c to store and manage the detection result in the management server device SVc when the seating detection result is not the seating of the monitored person Ob. If the seating detection result indicates that the person to be monitored Ob is seated, the processing is performed according to a sixth processing method that does not store the detection result in the management server device SVc. More specifically, the sixth processing method is a processing method which does not transmit the detection result to the management server device SVc. That is, in the fifth processing method, when the action detection processing unit 132 detects the predetermined action, the detection result processing unit 133c detects the first action when the seating detection result is not the seating of the monitored person Ob. The notification communication signal is transmitted by the SU communication IF unit 14 to the management server SVc. In the fifth processing method, even when the action detection processing unit 132 detects the predetermined action, the detection result processing unit 133 c performs the first action when the seating detection result indicates that the monitored person Ob is seated. Does not send detection notification communication signal.

Therefore, as a result, the detection result processing unit 133c can be 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 each of 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. Therefore, the description of the management server device SVc is omitted.

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

In the above embodiment, the detection result processing unit 133c is provided in the sensor device SUc, but 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 monitored person monitoring system of the modification in the third embodiment.

When the management server device SVc includes the 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 replaces the first detection result notification communication signal instead of the detection result processing unit 133c. Transmit to the management server SVc. In this case, in the first detection result notification communication signal, the sensor ID of the own device, information indicating the content of the predetermined action in the detected monitored person Ob (in this embodiment, among the bed leaving, falling and falling) Not only is the target image used to detect the predetermined action and the target image stored, but also the seating detection result (in the present embodiment, either seating presence or no seating) is also included Ru. The management server SVc not only functionally includes the SV control unit 221 and the SV monitoring processing unit 222 in the SV control processing unit 22 but also functionally includes 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 a predetermined action in the monitored person Ob. Based on the seating detection result of the seating detection unit 12 contained in the first detection result notification communication signal, processing is performed using different processing methods. 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 is not the seating of the monitored person Ob (in the case of no seating). The processing is performed by the fifth processing method for management, and when the seating detection result indicates that the person to be monitored Ob is seated (when seating is present), the management result is not stored in the management server SVc without being managed. Process by processing method. That is, in the above description, the SV monitoring processing unit 222 stores the monitoring information contained in the received first action detection notification communication signal in the SV storage unit 23 and manages it, so that the detection result processing unit in the management server SVc Allows the storage and management of the monitoring information by the SV monitoring processing unit 222 when the seating detection result is not the seating of the monitored person Ob (when there is no seating), and the seating detection result is for the monitored person Ob In the case of being seated (in the presence of seating), 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 embodiment, when the action detection processing unit 132 detects a predetermined action and the seating detection unit 12 detects no seating, the first detection result notification communication signal Furthermore, except for the fact that the seating detection result is accommodated, the processing of the above-described processing C1 to processing C5 shown in FIG. 12 is executed.

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 device SUc further detects seating presence as the seating detection result. The received first action detection notification communication signal is transmitted to the management server device SVc (C32). When the management server device SVc receives the first action detection notification communication signal, the management server device SVc discards the monitoring information according to the seating detection result of the seating presence accommodated in the received first action detection notification communication signal, and does not store it. Do not manage (C33).

Although the present specification discloses various aspects of the technology as described above, the main technologies are summarized below.

Preferably, in the above-mentioned person-to-be-monitored monitoring support system, the sensor device generates an image in which the shape of the person to be monitored is copied, and detects the predetermined action based on the generated image.

The seating detection unit detects the presence or absence of seating on the monitored person. For this reason, when the seating detection unit detects seating of the monitored person when the sensor device detects the predetermined behavior, the monitored person Ob is seated, the detection result of the predetermined behavior There is a high possibility of false detection, and the detection result can be corrected by the seating detection result of the seating detection unit. Since the above-mentioned person-to-be-monitored monitoring support system processes the detection result based on the seating detection result of the seating detection unit, the reliability of the detection result can be enhanced, and therefore, notification can be issued more appropriately.

In another aspect, in the monitored person monitoring support system described above, the detection result processing unit causes the terminal device to display the detection result when the seating detection result is not the seating of the monitored person.

It is a display mode showing that the degree of reliability is lower.

If the seating detection unit detects seating of the monitored person when the sensor device detects the predetermined behavior, the monitored person is seated, so the detection result of the predetermined behavior is seating detection. The reliability is lower than when the unit does not detect the seating of the monitored person, and the detection result can be corrected by the seating detection result of the seating detection unit. The monitored person monitoring support system changes the display mode of the detection result based on the seating detection result of the seating detection unit. Therefore, the detection result based on the seating detection result of the seating detection unit from the display mode The reliability of the detection result can therefore be recognized more appropriately with the reliability of the detection result.
