Description

Monitored person monitoring apparatus, method and system

The present invention relates to a monitored person monitoring apparatus, a monitored person monitoring method, and a monitored person monitoring system for monitoring a monitored person to be monitored.

Japan (Japan) is an aging society, more specifically the ratio of population over 65 years old to the total population due to the improvement of living standards accompanying the post-war high economic growth, improvement of sanitary environment and improvement of medical standards, etc. It is a super-aging society with an aging rate exceeding 21%. In 2005, the elderly population aged 65 and over was about 25.56 million compared to the total population of 127.65 million, whereas in 2020, the elderly population was about 124.11 million. The population is predicted to be about 34.56 million. In such an aging society, nurses who need nursing or nursing care due to illness, injury, elderly age, etc., or those who need nursing care (such as those who require nursing care) are those who need nursing in a normal society that is not an aging society. This is expected to increase more than Japan, for example, is a society with a declining birthrate with a total fertility rate of 1.43 in 2013. For this reason, elderly care has been taking place in which elderly nurses, etc., are cared for by an elderly family (spouse, child, brother).

Employees requiring nursing care, etc. enter hospitals and facilities for welfare for the elderly (Japanese elderly law short-term entrance facilities, nursing homes for the elderly and special nursing homes for the elderly, etc.) and receive nursing and care. In such a facility, a situation in which a nurse or the like needs to be injured or fallen out of the bed, for example, by falling from the bed or falling while walking can occur. It is necessary to respond to such a situation as quickly as possible. Moreover, if such a situation is left unattended, it may develop into a more serious situation. For this reason, in the facility, nurses and caregivers regularly check their safety and state by patrol.

However, the increase in the number of nurses etc. cannot keep up with the increase in the number of nurses required, and the nursing industry and the care industry are chronically short of manpower. Furthermore, since the number of nurses, caregivers, and the like is reduced in the semi-night work and night work hours compared to the day work hours, the work load per person increases, and thus the work load is required to be reduced. In addition, the situation of the elderly care is not an exception in the facility, and it is often seen that elderly nurses and the like care for elderly nurses and the like. In general, physical strength declines when older, so the burden of nursing etc. becomes heavier than young nurses etc. even if they are healthy, and their movements and judgments are also delayed.

In order to reduce the labor shortage and the burden on nurses, a technology that complements nursing work and nursing care work is required. For this reason, in recent years, monitored person monitoring techniques for monitoring a monitored person to be monitored, such as a care recipient, have been researched and developed.

For example, there is a nurse call system disclosed in Patent Document 1 as one of such techniques. The nurse call system disclosed in Patent Document 1 is a nurse call slave set that is installed in a bed and a patient calls a nurse, and a nurse call set that is installed in a nurse station and responds to a call by the nurse call slave set. A nurse call system having a nurse call parent device, a camera for imaging a patient on a bed from above the bed, and a state in which the patient wakes up from a captured image of the camera and a state in which the patient is separated from the bed State judging means for judging the occurrence of at least one of them and outputting a caution state occurrence signal, and the nurse call master unit has a notifying means for performing a notification operation upon receiving the caution state occurrence signal. The nurse call system transmits a captured image of the camera to the portable terminal upon receiving the attention state generation signal and a portable terminal carried by a nurse to respond to a call from the nurse call slave. Communication control means.

On the other hand, in terms of safety confirmation, a single person living alone is the same as the care recipient and the like and is a subject to be monitored.

By the way, when a monitor such as a nurse normally receives a notification of a predetermined event related to a monitored person such as a nurse in need of a terminal device, an appropriate countermeasure (measure, Take action and action). Here, when there are a relatively large number of persons to be monitored, the nurse call system disclosed in Patent Document 1 accepts a plurality of notifications by a terminal device, and it takes time to deal with one notification. Unhandled notifications stay in the terminal device. When such an unhandled notification stays in the terminal device, and when a new notification is received by the terminal device, the supervisor takes time to start the handling of the new notification. It becomes difficult to implement appropriate countermeasures, such as failure to implement the countermeasures for the new notification.

The network NW constitutes a so-called intranet by using Internet protocol groups such as TCP (Transmission control protocol) and IP (Internet protocol).

The monitored person monitoring system MSa is arranged at an appropriate place according to the monitored person Ob. The monitored person (person to be watched) 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, a single person living alone, or the like. In particular, from the viewpoint of enabling early detection and early action, the monitored person Ob may be a person who needs the detection when a predetermined inconvenient event such as an abnormal state occurs in the person. preferable. For this reason, the monitored person monitoring system MSa is suitably arranged in a building such as a hospital, an elderly welfare facility, or a dwelling unit according to the type of the monitored person Ob. In the example illustrated in FIG. 1, the monitored person monitoring system MSa is disposed in a building of a care facility that includes a plurality of rooms RM in which a plurality of monitored persons Ob and a plurality of rooms such as a nurse station.

The image includes a still image (still image data) and a moving image (moving image data). The imaging unit 11 is disposed so as to be able to monitor a space (location space, in the example shown in FIG. 1, where the monitored person Ob that is a monitoring target to be monitored) is located. The space is imaged as an imaging target from above, an image (image data) overlooking the imaging target is generated, and the imaging target image (target image) is output to the SU control processing unit 14. Preferably, since there is a high probability that the entire monitored person Ob can be imaged, the imaging unit 11 is expected to be located at the head of the monitored person Ob in the bedding on which the monitored person Ob is lying (for example, a bed). It is arranged so that the imaging target can be imaged from directly above the preset planned head position (usually the position where the pillow is disposed). The sensor device SU uses the imaging unit 11 to acquire an image of the monitored person Ob taken from above the monitored person Ob, preferably an image 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 place. . For example, in this embodiment, the imaging unit 11 has an imaging optical system that forms an infrared optical image of an imaging target on a predetermined imaging surface, and a light receiving surface that matches the imaging surface. An image sensor that is arranged and converts an infrared optical image in the imaging target into an electrical signal, and image data that represents an infrared image in the imaging target by performing image processing on the output of the image sensor It is a digital infrared camera provided with the image processing part etc. which produce | generate. In the present embodiment, the imaging optical system of the imaging unit 11 is preferably a wide-angle optical system (so-called wide-angle lens (including a fisheye lens)) having an angle of view that can image the entire living room RM in which the imaging unit 11 is disposed. .

The SU sound input / output unit 12 is a circuit that inputs and outputs sound. That is, the SU sound input / output unit 12 is a circuit that is connected to the SU control processing unit 14 and generates and outputs a sound corresponding to an electrical signal representing sound according to the control of the SU control processing unit 14. It is a circuit for acquiring the sound of and inputting it into the sensor device SU. The SU sound input / output unit 12 includes, for example, a speaker that converts a sound electrical signal (sound data) into a sound mechanical vibration signal (acoustic signal), and a microphone that converts a sound mechanical vibration signal in the audible region into an electrical signal. And so on. The SU sound input / output unit 12 outputs an electric signal representing an external sound to the SU control processing unit 14, and converts the electric signal input from the SU control processing unit 14 into a sound mechanical vibration signal and outputs the sound. .

The nurse call reception operation unit 13 is connected to the SU control processing unit 14 and is a switch circuit such as a push button switch for inputting the nurse call to the sensor device SU. Note that the nurse call reception operation unit 13 may be connected to the SU control processing unit 14 by wire, or may be connected to the SU control processing unit 14 by short-range wireless communication such as Bluetooth (registered trademark) standard.

The SU communication IF unit 15 is a communication circuit that is connected to the SU control processing unit 14 and performs communication according to the control of the SU control processing unit 14. The SU communication IF unit 15 generates a communication signal containing data to be transferred input from the SU control processing unit 14 according to a communication protocol used in the network NW of the monitored person monitoring system MSa, and the generated communication The signal is transmitted to other devices SVa, SP and TAa via the network NW. The SU communication IF unit 15 receives communication signals from other devices SVa, SP, and TAa via the network NW, extracts data from the received communication signals, and the SU control processing unit 14 can process the extracted data. The data is converted into data in a proper format and output to the SU control processing unit 14. The SU communication IF unit 15 includes, for example, a communication interface circuit that complies with the IEEE 802.11 standard or the like.

The SU storage unit 16 is a circuit that is connected to the SU control processing unit 14 and stores various predetermined programs and various predetermined data under the control of the SU control processing unit 14. Examples of the various predetermined programs include a SU control program that controls each unit of the sensor device SU according to the function of each unit, and a SU monitoring processing program that executes predetermined information processing related to monitoring of the monitored person Ob. And the like. The SU monitoring process program detects a predetermined action in the monitored person Ob and notifies a predetermined terminal apparatus SP, TAa via the management server apparatus SVa of the detection result as an example of the predetermined event. When a nurse call is received by the program or the nurse call reception operation unit 13, the management server device SVa is notified as another example of the predetermined event, and the terminal device is used by using the SU sound input / output unit 12 or the like. A SU nurse call processing program for making a voice call with SP and TAa, a SU streaming processing program for streaming the moving image generated by the imaging unit 11 to the terminal device SP and TAa that requested the moving image, and the like are included. . For each of the various predetermined data, each program such as a sensor device identifier (sensor ID) that is an identifier for identifying and identifying the sensor device SU of the own device and a communication address of the management server device SVa is executed. Data necessary for doing this is included. The SU storage unit 16 includes, for example, a ROM (Read Only Memory) that is a nonvolatile storage element, an EEPROM (Electrically Erasable Programmable Read Only Memory) that is a rewritable nonvolatile storage element, and the like. The SU storage unit 16 includes a RAM (Random Access Memory) serving as a working memory of the so-called SU control processing unit 14 that stores data generated during execution of the predetermined program.

The SU control processing unit 14 controls each unit of the sensor device SU according to the function of each unit, and notifies the management server device SVa of a predetermined event (event) related to the monitored person Ob that needs to be dealt with. It is a circuit for. More specifically, in this embodiment, the SU control processing unit 14 detects a predetermined action in the monitored person Ob and notifies the management server device SVa of the detection result as an example of the predetermined event (notification, Send), receive the nurse call, notify (notify, send) the nurse call to the management server device SVa as another example of the predetermined event, make a voice call with the terminal devices SP and TAa, and Then, an image including a moving image is generated and the moving image is distributed to the terminal devices SP and TAa. The SU control processing unit 14 includes, for example, a CPU (Central Processing Unit) and its peripheral circuits. The SU control processing unit 14 executes a sensor processing unit (SU control unit) 141, a behavior detection processing unit 142, a nurse call processing unit 143, and a sensor side streaming processing unit (SU streaming processing) by executing the control processing program. Part) 144 is functionally provided.

The SU control unit 141 controls each part of the sensor device SU according to the function of each part, and governs overall control of the sensor device SU.

The behavior detection processing unit 142 detects a predetermined behavior preset in the monitored person Ob and notifies the management server device SV of the detection result as an example of the predetermined event. More specifically, in the present embodiment, the predetermined action includes, for example, wake-up when the monitored person Ob occurred, leaving the monitored person Ob away from the bedding, falling down when the monitored person Ob fell from the bedding, And four actions of the fall where the monitored person Ob fell. For example, the behavior detection processing unit 142 detects the monitored person Ob based on the target image captured by the imaging unit 11, and wakes up, leaves, falls, and falls of the monitored person Ob based on the detected monitored person Ob. Is detected. Since the imaging unit 11 is disposed above the monitored person Ob, when the user wakes up, the monitored person Ob appears outside the bedding BD in the image. For this reason, the success or failure of the wake-up is determined based on, for example, the amount (area) of the monitored person Ob protruding from the bedding BD. When the person leaves the bed, the monitored person Ob appears in the image away from the bedding BD. For this reason, the success or failure of the bed leaving is determined based on the distance between the bedding BD and the monitored person Ob, for example. When falling or falling, the entire monitored person Ob appears larger in the image than the size before falling or falling. On the image, for example, the size of the monitored person Ob in the lying position due to falling or falling is more than twice the size of the monitored person Ob in the standing position. For this reason, the success or failure of the fall is determined based on the size (area, size) of the monitored person Ob on the image (for example, the lying posture of the monitored person Ob) in the predetermined bedding peripheral region. It is determined on the basis of the time required until the size is considered to be. The success or failure of the fall is determined based on the time required until the size of the monitored person Ob on the image reaches the preset size in the region of the room RM excluding the preset bedding peripheral region. The In addition, when falling or falling, the head of the monitored person Ob appears smaller in the image than the size before falling or falling. For example, the size of the head of the monitored person Ob in the lying posture due to falling or falling is ½ times or less the size of the head of the monitored person Ob in the standing posture. Therefore, the success or failure of the fall is determined based on the time required until the size of the head of the monitored person Ob on the image reaches a preset size in a preset bedding peripheral region. May be. The success or failure of the fall is based on the time required until the size of the head of the monitored person Ob on the image reaches a preset size in the region of the room RM excluding the preset bedding peripheral region. May be determined.

More specifically, first, the location area of the bedding BD, the threshold for determining success or failure of the wake-up (wake-up threshold), the threshold for determining success or failure of the wake-up (leave-off threshold), and success or failure of the fall or fall are determined. The SU storage unit 16 is stored in advance as a threshold (falling / falling threshold) for determination as one of the various predetermined data. And the action detection process part 142 extracts a moving body area | region as a human body area | region of the to-be-monitored person Ob from a target image by the background difference method or the frame difference method, for example. First, in order to determine the success or failure of the wake-up, the behavior detection processing unit 142 obtains the size (area) of the body movement region that protrudes from the region where the bedding BD is located as the amount of protrusion, and the amount of protrusion calculated is the amount of protrusion. It is determined whether or not the threshold value is exceeded. As a result of this determination, the behavior detection processing unit 142 determines that the user protrudes when the protruding amount is equal to or greater than the rising threshold value, and does not determine that the protruding amount is lower than the rising threshold value. Secondly, in order to determine success or failure of getting out of bed, the behavior detection processing unit 142 obtains the center of gravity position of the body movement region, obtains the distance between the obtained center of gravity position and the bedding BD, and the obtained distance is a bed leaving threshold. It is determined whether it is above. As a result of this determination, the behavior detection processing unit 142 determines that the person is getting out of bed when the distance is equal to or greater than the threshold for getting out of bed, and does not determine that the person is out of bed when the distance is less than the threshold of getting out of bed. Third, in order to determine the success or failure of the fall, the behavior detection processing unit 142 detects whether or not the body motion region starts to change over time, and measures the time when the body motion region starts to change over time. First, it is determined whether or not the size of the monitored subject Ob on the image has reached a preset size. As a result of this determination, if the size of the monitored person Ob on the image does not reach the preset size, the behavior detection processing unit 142 ends the time measurement and resets it. When the size of the monitored person Ob becomes a preset size, the time measurement is terminated to obtain the position of the center of gravity of the body movement area, and whether or not the time measured is within the fall / fall threshold. And it is determined whether the gravity center position of a body movement area | region is within the bedding peripheral area | region. As a result of this determination, if the time exceeds the fall / fall threshold, the behavior detection processing unit 142 determines that the fall / fall did not occur, and the time is within the fall / fall threshold and the center of gravity of the body movement region If the position is within the bedding peripheral area, it is determined to fall, and if the time is within the fall fall threshold and the center of gravity position of the body movement area is not within the bedding peripheral area, it is determined to fall. In addition, when determining the success or failure of a fall or the success or failure of a fall using the size of the head, the behavior detection processing unit 142 may perform, for example, a circular or elliptical Hough transform, for example, a head prepared in advance. The head region of the monitored person Ob may be extracted from the moving object region by pattern matching using a model or by a neural network learned for head detection, for example.

When the predetermined behavior is detected in this manner, the behavior detection processing unit 142 notifies the management server device SV of the detection result and the target image used when obtaining the detection result by the SU communication IF unit 15. To do. More specifically, the behavior detection processing unit 142 includes a sensor signal (first information) that contains a sensor ID of the own device, event information (event information) indicating the content of the event, and a target image used for detection of the predetermined behavior. 1 event notification communication signal) is transmitted to the management server device SV via the SU communication IF unit 15. In the present embodiment, the event information (event information) is one or more of getting up, getting out of bed, falling, falling, and nurse call (NC). Here, the behavior detection processing unit 142 is for getting up, getting out of bed. One or more of falls and falls are set in the event information. The image may be at least one of a still image and a moving image. In the present embodiment, as described later, first, a still image is notified, and the moving image is distributed in response to a user request. First, a moving image may be distributed, a still image and a moving image may be transmitted, and the still image and the moving image may be displayed on the terminal devices SP and TAa by screen division.

When the nurse call receiving unit 13 receives a nurse call, the nurse call processing unit 143 notifies the management server SVa as another example of the predetermined event, and uses the SU sound input / output unit 12 or the like. Thus, a voice call is performed between the terminal devices SP and TAa. More specifically, the nurse call processing unit 143 receives the first event notification communication signal containing the sensor ID of the own device and the event information (event information) when the nurse call reception operation unit 13 is input. The data is transmitted to the management server device SVa via the SU communication IF unit 15. The nurse call processing unit 143 sets a nurse call (NC) in the event information. The nurse call processing unit 143 uses the SU sound input / output unit 12 and the like to perform a voice call with the terminal devices SP and TAa by, for example, VoIP (Voice over Internet Protocol).

When there is a video distribution request from the fixed terminal device SP or the portable terminal device TAa via the communication IF unit 3, the SU streaming processing unit 144 sends the request to the fixed terminal device SP or the portable terminal device TAa that has made this request. The moving image generated by the imaging unit 11 (for example, a live moving image) is distributed via the SU communication IF unit 15 by streaming reproduction.

On the other hand, in FIG. 10, the management server device SVa determines whether or not the SV communication IF unit 21 has received a communication signal by the SV control unit 221 of the SV control processing unit 22a (S21). As a result of the determination, if the communication signal is not received (No), the management server device SVa returns the process to S21. If the result of the determination is that the communication signal is received (Yes), The management server device SVa executes the following process S22. That is, the management server device SVa waits for reception of a communication signal.

In process S22, the management server device SVa determines the type of the received communication signal by the SV control unit 221. As a result of this determination, when the received communication signal is the first event notification communication signal (first event notification), the management server device SVa executes the process S26 after executing the process S23, and receives the received If the communication signal is a situation information notification communication signal (situation information notification), the process S26 is executed after the process S24, and the received communication signal is the first event notification communication signal and the situation information notification. If it is not a communication signal (others), the process S26 is executed after the process S25.

In the processing S23, the management server device SVa processes the first event notification communication signal received from the sensor device SU in the processing S21 by the SV monitoring processing unit 222a of the SV control processing unit 22a. More specifically, first, the SV monitoring processing unit 222a displays monitoring information related to monitoring of the monitored person Ob stored in the first event notification communication signal received from the sensor device SU in step S21. 231 is stored (recorded). Then, the SV monitoring processing unit 222a selects a notification destination corresponding to the sensor device SU that has transmitted the first event notification communication signal received in step S21 from the notification destination correspondence relationship stored in the inter-device information storage unit 232 ( Search for. Next, the SV monitoring processing unit 222a transmits the second event notification communication signal to the selected notification destination terminal devices SP and TAa based on the status information of the selected notification destination terminal devices SP and TAa. Control. More specifically, the SV monitoring processing unit 222a first determines the terminal IDs of the notification destination terminal devices SP and TAa from the first situation information table CTa stored in the situation information storage unit 233a of the SV storage unit 23a. The record to be registered in the field 2331 is searched, and the stay notification count information registered in the stay notification count information field 2332 of the searched record is extracted. Then, the SV monitoring processing unit 222a determines whether or not the number of staying notifications of the terminal device SP and TAa that are the notification destinations exceeds the notification suppression threshold based on the extracted number of staying notifications information, and the notification destination If the number of stay notifications of the terminal devices SP and TAa does not exceed the notification suppression threshold, the second event notification communication signal generated from the first event notification communication signal received in the processing S21 is generated and transmitted as it is. On the other hand, when the number of staying notifications of the notification destination terminal devices SP and TAa exceeds the notification suppression threshold, control is performed to suppress transmission of the second event notification communication signal. For example, the SV monitoring processing unit 222a stops transmitting the second event notification communication signal without generating the second event notification communication signal. Further, for example, the SV monitoring processing unit 222a generates and transmits the second event notification communication signal according to the priority of the predetermined event stored in the first event notification communication signal received in the processing S21. Further, for example, the SV monitoring processing unit 222a generates and transmits the second event notification communication signal by thinning. More specifically, when the second event notification communication signal is generated and transmitted at a rate of once every two times, the SV monitoring processing unit 222a performs the previous transmission in the second event notification communication signal for each terminal ID. Presence / absence is stored in the SV storage unit 23a, and if the second event notification communication signal has been transmitted last time, the SV monitoring processing unit 222a stops the current transmission and transmits the second event notification communication signal. If it has not been transmitted last time, the current transmission is executed.

In process S24, the management server device SVa uses the status information storage processing unit 223a of the SV control processing unit 22a to store the stay notification number information contained in the status information notification communication signal received from the terminal device SP and TAa in step S21. The information is stored in the status information storage unit 233a in association with the terminal devices SP and TAa. More specifically, the situation information storage processing unit 223a accommodates the situation information notification communication signal received in this process S21 from the first situation information table CTa stored in the situation information storage unit 233a of the SV storage unit 23a. The terminal ID field 2331 is searched for the record registered, and the stay notification number information field 2332 of the searched record stores the stay notification number information accommodated in the status information notification communication signal received in the processing S21. Is registered, and the registration content of this stay notification number information field 2332 is updated. Thus, the latest information on the number of staying notifications in the terminal devices SP and TAa is stored in the status information storage unit 233a.

In the process S25, the management server apparatus SVa performs an appropriate process according to the communication signal received in the process S21 by the SV control processing unit 22a.

And in the process S26 executed after each of these processes S23 to S25, the management server apparatus SVa determines whether or not its operation is completed (stopped) by the SV control processing unit 22a. As a result of this determination, when the operation is finished (stopped) (Yes), the management server device SVa finishes this process. On the other hand, when the operation is not finished (stopped) (No), the management server device SVa The server apparatus SVa returns the process to process S21.

Regarding the first event notification communication signal received from the sensor device SU and the status information notification communication signal received from the terminal devices SP and TAa, the monitoring server device SVa operates as described above.

Next, the operation of the terminal devices SP and TAa will be described. Here, typically, operation | movement of portable terminal device TAa is demonstrated. As described above, when the power is turned on and the operation thereof is started, the portable terminal device TAa accepts a login operation by a monitor (user) such as a nurse or a caregiver, and the TA monitor processor 322a automatically A standby screen for waiting for a communication signal addressed to the machine is displayed on the TA display unit 36. For example, as shown in FIG. 13, the standby screen 51 includes a menu bar area 511 for displaying a menu bar, and a standby main area for displaying a message indicating standby (for example, “no notification”) and an icon. 512, a time area 513 for displaying the current time, a year / month / sunday area 514 for displaying the current year / month / sunday, and a user name area 515 for displaying the name of the user who is currently logged in to the portable terminal device TA. Is provided.

Then, in FIG. 11, the portable terminal device TAa determines whether or not the TA communication IF unit 31 has received a communication signal by the TA control unit 321 of the TA control processing unit 32a (S31). If the communication signal is not received as a result of this determination (No), the portable terminal device TAa returns the process to S31, and if the communication signal is received as a result of the determination (Yes), The portable terminal device TAa performs the following process S32. That is, the portable terminal device TAa is waiting for reception of a communication signal.

In process S32, the portable terminal device TAa determines the type of the received communication signal by the TA control unit 321. As a result of this determination, when the communication signal received in the process S31 is the second event notification communication signal (second event notification), the portable terminal device TAa executes the next process S33, and in the process S31. When the received communication signal is not the second event notification communication signal (others), the process ends after executing the process S37 for performing an appropriate process according to the communication signal received in the process S31.

In the process S33, the mobile terminal device TAa monitors the monitored person Ob contained in the second event notification communication signal received from the management server apparatus SVa in the process S31 by the TA monitoring processing unit 322a of the TA control processing unit 32a. Is stored (recorded) in the TA monitoring information storage unit 331.

After this processing S33, the TA monitoring processing unit 322a displays a screen corresponding to each information accommodated in the second event notification communication signal received in processing S31 on the TA display unit 36. More specifically, when the event information accommodated in the second event notification communication signal received in step S31 is the predetermined action, the TA monitoring processing unit 322a, for example, the monitoring information illustrated in FIG. When the screen 52 is displayed on the TA display unit 36 and the event information accommodated in the second event notification communication signal received in step S31 is the nurse call, for example, a nurse call reception shown in FIG. A screen 53 is displayed on the TA display unit 36.

The monitoring information screen 52 is a screen for displaying the monitoring information related to the monitoring of the monitored person Ob. For example, as shown in FIG. 14, the monitoring information screen 52 includes a menu bar area 511, an arrangement location of the sensor device SU having the sensor ID accommodated in the second event notification communication signal received in step S <b> 31, and the monitoring information screen 52.

Received in the second event notification communication signal (that is, the target image captured by the sensor device SU having the sensor ID) ) (Here includes an image area 523 for displaying a still image), "corresponding" button 524, a "talk" button 525, a "See LIVE" button 526.

In order to display the installation location of the sensor device SU and the name of the monitored subject Ob in the monitored person name area 521, the TA storage unit 33 displays the installation location of the sensor device SU having the sensor ID and the sensor ID. And the name of the monitored person Ob monitored by the sensor device SU having the sensor ID is stored in advance in association with each other. In the detection information display area 522, the detection results (in this embodiment, names of getting up, getting out of bed, falling down, and falling down) contained in the second event notification communication signal received in step S31 may be displayed as they are. However, in this embodiment, it is displayed with an icon that symbolically represents the detection result. In order to display this icon, the TA storage unit 33 stores each action and an icon representative of the action in association with each other in advance. In the example illustrated in FIG. 14, the detection information display area 522 displays a wake-up icon that symbolizes wake-up. In the monitoring information screen 52, the “corresponding” button 524 has an intention to perform a predetermined response (response, response) such as lifesaving, nursing, care, and assistance for the detection result displayed on the monitoring information screen 52. This is a button for inputting implementation intention information indicating that the user of the mobile terminal device TAa is present to the mobile terminal device TAa. Then, as will be described later, when the input operation of the “corresponding” button 524 is accepted, the portable terminal device TAa transmits a status information notification communication signal to the management server device SVa. A “speak” button 525 is a button for requesting a voice call, and is used to input an instruction to connect the sensor device SU of the sensor ID and the mobile terminal device TAa so as to be able to talk over the network NW. It is a button. The “LIVE” button 526 is a button for requesting a live video, and is a button for inputting an instruction to display a video captured by the sensor device SU of the sensor ID.

The nurse call reception screen 53 is a screen for displaying reception of a nurse call. As shown in FIG. 15, for example, the nurse call reception screen 53 includes a menu bar area 511, a monitored person name area 521, a detection information display area 522, and a message indicating that a nurse call has been received (for example, “ Nurse call reception notification display area 531 for displaying “This is a nurse call”, a “corresponding” button 524, and a “speak” button 525. In the nurse call reception screen 53, the detection information display area 522 displays only the elapsed time from the reception time of the second event notification communication signal received in step S31 (or the reception time of reception of the nurse call). .

Note that the nurse call reception screen 53 may further include a “view LIVE” button 526.

Then, after the process S34, the portable terminal device TAa determines whether or not an input operation has been accepted by the TA control processing unit 32a on the touch panel including the TA input unit 35 and the TA display unit 36 (S35). If the input operation is not accepted as a result of this determination (No), the portable terminal device TAa returns the process to step S35. On the other hand, if the input operation is accepted as a result of the determination, the portable terminal device TAa returns The device TAa performs the next process S36a.

In this process S36a, the portable terminal device TAa performs an appropriate process according to the content of the input operation by the TA control processing unit 32a, and ends this process.

For example, when the portable terminal device TAa receives an input operation of the “corresponding” button 524 by the TA control processing unit 32a (ie, accepts the corresponding intention), first, the TA display unit 36 in FIG. Is added to the monitoring information of the monitored person Ob displayed in the table, and “corresponding” is accepted and stored in the TA monitoring information storage unit 331 (S41). More specifically, the TA control processing unit 32a is the monitored target currently displayed on the TA display unit 36 in the monitoring information table MT-TA stored in the TA monitoring information storage unit 331 of the TA storage unit 33. The correspondence field 3316 of the record in which the monitoring information of the person Ob is registered (here, the record in which the monitoring information contained in the second event notification communication signal received in the process S31 is registered) Register the flag “1”. Next, the mobile terminal device TAa receives information indicating that a sensor ID corresponding to the monitoring information of the monitored person Ob displayed on the TA display unit 36 and “corresponding” have been received by the TA control processing unit 32a ( A communication signal (correspondence acceptance notification communication signal) containing the correspondence acceptance information) is transmitted to the management server device SVa (S42). The management server device SVa that has received the correspondence reception notification communication signal, by the SV control processing unit 22a, has received a communication signal (correspondence reception known communication) containing the sensor ID and the correspondence reception information contained in the received correspondence reception notification communication signal. Signal) to the terminal devices SP and TAa by broadcast communication. As a result, regarding the sensor ID corresponding to the monitoring information of the monitored person Ob displayed on the TA display unit 36, the fact that “corresponding” has been received is synchronized between the terminal devices SP and TAa. Next, in order to transmit the status information notification communication signal containing the terminal ID of the own device and the stay notification number information as the status information to the management server device SVa, the portable terminal device TAa performs the TA monitoring process of the TA control processing unit 32a. The unit 322a retains the number of records in which the correspondence flag “0” indicating uncorrespondence is registered in the correspondence field 3316 from the monitoring information table MT-TA stored in the TA monitoring information storage unit 331 of the TA storage unit 33. The information is totaled as notification number information (S43). Then, the portable terminal device TAa generates a status information notification communication signal containing the stay notification number information obtained by this total and the terminal ID of the own device by the TA monitoring processing unit 322a of the TA control processing unit 32a. The generated status information notification communication signal is transmitted to the management server device SVa (S44). The management server device SVa that has received this status information notification communication signal updates the registration contents of the first status information table CTa stored in the status information storage unit 233a as described above. In the above description, the mobile terminal apparatus TAa individually generates the correspondence reception notification communication signal and the status information notification communication signal and transmits them to the management server apparatus SVa. You may transmit to SVa. When the input operation of the “corresponding” button 524 is accepted, the portable terminal device TAa operates in this way.

In addition, for example, when the mobile terminal device TAa receives an input operation of the “speak” button 525 by the TA control processing unit 32a, the call processing unit 323 monitors the monitored person Ob displayed on the TA display unit 36. A communication signal (call request communication signal) containing information such as requesting a voice call is transmitted to the sensor device SU, and the sensor device SU is connected to the sensor device SU via the network NW so as to be able to make a voice call. As a result, a voice call can be performed between the portable terminal device TAa and the sensor device SU. In addition, when the TA control processing unit 32a receives an input operation of an “end” button (not shown) that is a button for inputting an instruction to end a voice call, the portable terminal device TAa causes the call processing unit 323 to A communication signal (call end communication signal) containing information such as a request to end the voice call is transmitted to the sensor device SU that monitors the monitored person Ob displayed on the display unit 36. As a result, the voice call between the portable terminal device TAa and the sensor device SU is terminated.

Further, for example, when the mobile terminal device TAa receives an input operation of the “watch live” button 526 by the TA control processing unit 32a, the TA streaming processing unit 324 displays the monitored object currently displayed on the TA display unit 36. A communication signal (video distribution request communication signal) containing information such as requesting live video distribution is transmitted to the sensor device SU that monitors the person Ob, and the sensor device SU and the network NW corresponding thereto are transmitted. The video is connected to be downloadable via the sensor device SU, receives live video distribution from the sensor device SU, and displays the distributed video on the TA display unit 36 by streaming playback. On the monitoring information screen 52 that displays the live video, the video is displayed in the image area 523, and a “live end” button (not shown) is displayed instead of the “view live” button 526. Thereby, live video is displayed on the mobile terminal device TAa. The “live end” button (not shown) is a button for requesting the end of the moving image, and ends (stops) the distribution of the moving image picked up by the sensor device SU of the sensor ID and ends (stops) the display. This is a button for inputting an instruction to be performed. When the TA control processing unit 32a accepts an input operation of the “live end” button, the portable terminal device TAa monitors the monitored person Ob currently displayed on the TA display unit 36 by the TA streaming processing unit 324. A communication signal (moving image distribution end communication signal) containing information such as requesting the end of moving image distribution is transmitted to the sensor device SU, and a still image is displayed on the TA display unit 36. Thereby, the mobile terminal device TAa ends the live video display.

Regarding the second event notification communication signal received from the management server device SVa, the mobile terminal device TAa operates as described above.

In the above description, when the input operation of the “corresponding” button 524 is received, the mobile terminal device TAa transmits the status information notification communication signal to the management server device SVa. Instead, the mobile terminal device TAa may transmit a status information notification communication signal to the management server device SVa at a predetermined time interval (for example, every 5 minutes, every 10 minutes, every 30 minutes, or the like).

As described above, the monitored person monitoring system MSa, the sensor apparatus SU and the management server apparatus SVa as an example of the monitored person monitoring apparatus, and the mounted monitored person monitoring method according to the present embodiment are as follows. Since the transmission of the second event notification communication signal resulting from the reception of the one event notification communication signal is controlled, when the terminal device SP and TAa are newly notified by the second event notification communication signal, the current terminal device SP It is possible to determine whether or not to execute a new notification by the second event notification communication signal according to the status of TAa. For this reason, the monitored person monitoring system MSa, the monitored person monitoring device (the sensor device SU and the management server device SVa), and the monitored person monitoring method have the second event notification communication that is excessive so that the countermeasure cannot be taken. It is possible to avoid performing notification by a signal to the terminal devices SP and TAa, and therefore, it is possible to more appropriately implement the countermeasure for the notification.

The monitored person monitoring system MSa, the monitored person monitoring device (the sensor device SU and the management server device SVa), and the monitored person monitoring method associate residence notification number information as status information with each of the terminal devices SP and TAa. Therefore, the current number of notifications staying in the terminal devices SP and TAa without being dealt with can be grasped, and when notifying the terminal devices SP and TAa newly by the second event notification communication signal, As a countermeasure, it is possible to determine whether or not to execute a new notification by the second event notification communication signal according to the current number of notifications staying in the terminal devices SP and TAa. For this reason, the monitored person monitoring system MSa, the monitored person monitoring device (the sensor device SU and the management server device SVa), and the monitored person monitoring method have the second event notification communication that is excessive so that the countermeasure cannot be taken. It is possible to avoid performing notification by a signal to the terminal devices SP and TAa, and therefore, it is possible to more appropriately implement the countermeasure for the notification.

The TA communication IF unit 31, the TA storage unit 33, the TA sound input / output unit 34, the TA input unit 35, the TA display unit 36, and the TAIF unit 37 in the portable terminal device TAb of the second embodiment are respectively the first embodiment. Since it is the same as the TA communication IF unit 31, the TA storage unit 33, the TA sound input / output unit 34, the TA input unit 35, the TA display unit 36, and the TAIF unit 37 in the portable terminal device TAa, the description thereof is omitted.

Similarly to the TA control processing unit 32a, the TA control processing unit 32b controls each unit of the mobile terminal device TAb according to the function of each unit, receives and displays the monitoring information of the monitored person Ob, and status information This is a circuit for transmitting a notification communication signal to the management server device SVb to answer or call a nurse call. The TA control processing unit 32b functionally includes a TA control unit 321, a TA monitoring processing unit 322b, a call processing unit 323, and a TA streaming processing unit 324 by executing a control processing program. The TA control unit 321, the call processing unit 323, and the TA streaming processing unit 324 in the TA control processing unit 32b are respectively the TA control unit 321, the call processing unit 323, and the TA streaming processing unit 324 in the TA control processing unit 32a. Since it is the same, the description is abbreviate | omitted.

The TA monitoring processing unit 322b executes predetermined information processing related to monitoring of the monitored person Ob. More specifically, when the TA monitoring processing unit 322b receives the second event notification communication signal from the management server device SVb, the TA monitoring processing unit 322b stores each information (each data) accommodated in the received second event notification communication signal. Based on this, the monitoring information of the monitored person Ob is stored (recorded) in the TA monitoring information storage unit 331. The TA monitoring processing unit 322b displays a screen corresponding to each piece of information contained in the received second event notification communication signal on the TA display unit 36.

Therefore, the TA monitoring processing unit 322b of the second embodiment does not have a processing function for transmitting a situation information notification communication signal, unlike the TA monitoring processing unit 322a of the first embodiment.

Next, the operation of the second embodiment will be described. FIG. 18 is a flowchart showing the operation of the management server device shown in FIG.

In the monitored person monitoring system MSb in the second embodiment as described above, the sensor device SU operates in the same manner as in the first embodiment by executing the processes S11 to S16 shown in FIG. The terminal devices SP and TAb execute processes S31 to S36b including a process S36b instead of the process S36a shown in FIG. That is, the terminal devices SP and TAb are the first implementation except that the status information notification communication signal is not transmitted in the process S36b (that is, the above-described processes S43 and S44 shown in FIG. 12 are not executed). Works like a form. On the other hand, the management server device SVb operates as follows.

18, the management server device SVb determines whether or not the SV communication IF unit 21 has received a communication signal by the SV control unit 221 of the SV control processing unit 22b (S51). As a result of this determination, when the communication signal is not received (No), the management server device SVb returns the process to S51, and when the result of the determination is that a communication signal is received (Yes), The management server device SVb executes the following process S52. That is, the management server device SVb waits for reception of a communication signal.

In process S52, the management server device SVb determines the type of the received communication signal by the SV control unit 221. As a result of this determination, when the received communication signal is the first event notification communication signal (first event notification), the management server device SVb executes the process S56 after executing the process S53 and the process S54 sequentially. If the received communication signal is not the first event notification communication signal (others), the process S56 is executed after executing the process S55 that executes an appropriate process according to the communication signal received in the process S51. Execute.

In the processing S53, the management server device SVb processes the first event notification communication signal received from the sensor device SU in the processing S51 by the SV monitoring processing unit 222b of the SV control processing unit 22b. More specifically, first, the SV monitoring processing unit 222b displays monitoring information related to monitoring of the monitored person Ob stored in the first event notification communication signal received from the sensor device SU in step S51. 231 is stored (recorded). Then, the SV monitoring processing unit 222b selects a notification destination corresponding to the sensor device SU that has transmitted the first event notification communication signal received in step S51 from the notification destination correspondence stored in the inter-device information storage unit 232 ( Search for. Next, the SV monitoring processing unit 222b transmits the second event notification communication signal to the selected notification destination terminal devices SP and TAb based on the status information of the selected notification destination terminal devices SP and TAb. Control. More specifically, the SV monitoring processing unit 222b first determines the terminal IDs of the notification destination terminal devices SP and TAb from the second situation information table CTb stored in the situation information storage unit 233b of the SV storage unit 23b. A record to be registered in the field 2333 is searched, and notification number information within a predetermined period registered in the notification number information field 2334 of the searched record is extracted. Then, the SV monitoring processing unit 222b determines whether or not the number of notifications within the predetermined period of the terminal device SP and TAb that are the notification destinations exceeds the second notification suppression threshold based on the extracted number of notifications within the predetermined period. If the number of notifications in the predetermined period of the terminal devices SP and TAb that are the notification destinations does not exceed the second notification suppression threshold, the first event notification communication signal received in step S51 is used as it is. 2 event notification communication signal is generated and transmitted. On the other hand, when the number of notifications within a predetermined period of the terminal devices SP and TAb of the notification destination exceeds the second notification suppression threshold, the second event notification communication Control to suppress signal transmission. For example, the SV monitoring processing unit 222b stops transmission of the second event notification communication signal without generating the second event notification communication signal. For example, the SV monitoring processing unit 222b generates and transmits the second event notification communication signal according to the priority of the predetermined event accommodated in the first event notification communication signal received in the processing S51. Further, for example, the SV monitoring processing unit 222b generates and transmits the second event notification communication signal by thinning.

After this processing S53, the management server device SVb performs status information processing (S54). More specifically, when the management server device SVb is transmitting the second event notification communication signal in the process S53, the management server device SVb first performs the second notification number information calculation unit 224 of the SV control processing unit 22b. The transmission time of the event notification communication signal is stored in association with the terminal device SP, TAb that is the destination of the second event notification communication signal, and the terminal device SP, TAb that is the destination of the second event notification communication signal, Based on the transmission time data, the total number of transmissions of the second event notification communication signal within the predetermined period from the present time is totaled, thereby obtaining the notification number information within the predetermined period. Subsequently, the management server device SVb registers, in the terminal ID field 2333, the terminal IDs of the terminal devices SP and TAb that are the transmission destinations of the second event notification communication signal by the status information storage processing unit 223b of the SV control processing unit 22b. The record is searched, and the notification number information within the predetermined period obtained by the notification number information calculation unit 224 within the predetermined period is registered in the notification number information field 2334 of the predetermined record, and the notification number information within the predetermined period is registered. The registered contents in the field 2334 are updated.

On the other hand, when the second event notification communication signal is not transmitted in the process S53, the management server apparatus SVb ends this process S54 without executing anything, and executes the next process S56.

In the process S56 executed after each of the processes S54 and S55, the management server apparatus SVb determines whether or not the operation is finished (stopped) by the SV control processing unit 22b. As a result of this determination, when the operation is finished (stopped) (Yes), the management server device SVb finishes this process, whereas when it is not the operation finished (stopped) (No), the management server device SVb The server device SVb returns the process to step S51.

Regarding the first event notification communication signal received from the sensor device SU, the monitoring server device SVb operates as described above.

As described above, the monitored person monitoring system MSb, the sensor apparatus SU and the management server apparatus SVb as an example of the monitored person monitoring apparatus, and the mounted monitored person monitoring methods in the second embodiment are as follows. As in the first embodiment, since the transmission of the second event notification communication signal resulting from the reception of the first event notification communication signal is controlled, the terminal device SP and TAb are newly notified by the second event notification communication signal. In this case, it is possible to determine whether or not to execute a new notification by the second event notification communication signal according to the current status of the terminal devices SP and TAb. For this reason, the monitored person monitoring system MSb, the monitored person monitoring device (the sensor device SU and the management server device SVb), and the monitored person monitoring method have the second event notification communication that is too large to cope with the problem. It is possible to avoid performing notification by signals to the terminal devices SP and TAb, and therefore, it is possible to more appropriately implement the countermeasure for the notification.

The monitored person monitoring system MSb, the monitored person monitoring device (the sensor device SU and the management server device SVb), and the monitored person monitoring method are configured to send notification number information within a predetermined period as status information to the terminal devices SP and TAb, respectively. Since the information is stored in association with each other, the current number of notifications notified to the terminal devices SP and TAb within a predetermined period can be grasped, and when the terminal devices SP and TAb are newly notified, the terminal within the predetermined period. Whether or not to execute the new notification can be determined according to the current number of notifications notified to the devices SP and TAb. For this reason, the monitored person monitoring system MSb, the monitored person monitoring device (the sensor device SU and the management server device SVb), and the monitored person monitoring method give an excessive notification that cannot be handled by the terminal device SP. , TAb can be avoided, and thus the above-mentioned response to the notification can be implemented more appropriately. Since the number of notifications notified to the terminal devices SP and TAb within a predetermined period can be grasped by the monitored person monitoring device (sensor device SU and management server device SVb), the monitored person monitoring device is not yet It is not necessary to receive the status information notification communication signal from the terminal devices SP and TAb like the number of notifications staying in the terminal devices SP and TAa.

(First to third modifications)
In the above-described embodiment, the management server device SV (SVa, SVb) sends the second event notification communication signal based on the first event notification communication signal to the predetermined terminal device SP, TA (TAa, TAb) based on the situation information associated with the predetermined terminal device SP, TA stored in the situation information storage unit 233 (233a, 233b) of the SV storage unit 23 (23a, 23b). The transmission of the second event notification communication signal to the predetermined terminal devices SP and TA is controlled. In the first embodiment, the management server device SVa determines whether or not the number of stay notifications of the notification destination terminal devices SP and TAa exceeds the notification suppression threshold (first notification suppression threshold) by the SV monitoring processing unit 222a. Then, when the number of staying notifications of the notification destination terminal devices SP and TAa exceeds the notification suppression threshold, control is performed to suppress transmission of the second event notification communication signal. In the second embodiment, the management server device SVb determines whether or not the number of notifications within a predetermined period of the notification destination terminal devices SP and TAb exceeds the second notification suppression threshold by the SV monitoring processing unit 222b. When the number of notifications in the predetermined period of the previous terminal device SP, TAa exceeds the second notification suppression threshold, control is performed to suppress transmission of the second event notification communication signal. The control for suppressing the transmission of the second event notification communication signal is executed by immediate stop of transmission, stop by priority of transmission, thinning of transmission, etc., but is not limited to this. For example, it may be executed based on the detection sensitivity for detecting the predetermined action. Also according to the detection sensitivity, it can be controlled to suppress the transmission of the second event notification communication signal. Hereinafter, first to third modifications that suppress transmission of the second event notification communication signal with such detection sensitivity will be described.

FIG. 19 is a flowchart showing the operation of the first mode in the management server device when the transmission of the second event notification communication signal is controlled with the detection sensitivity corresponding to the situation information. FIG. 20 is a flowchart showing the operation of the second mode in the management server device when the transmission of the second event notification communication signal is controlled with the detection sensitivity according to the situation information. FIG. 21 is a flowchart showing the operation of the third mode in the management server device when the transmission of the second event notification communication signal is controlled with the detection sensitivity according to the situation information.

In the first to third modifications to the monitored person monitoring systems MSa and MSb in the first and second embodiments, when the sensor device SU detects the predetermined action, the action detection in the process S12 shown in FIG. The process is executed with a plurality of detection sensitivities, and in the first event notification communication signal transmission process of the process S14 shown in FIG. 9, each detection result at each of the plurality of detection sensitivities is associated with each detection sensitivity. It is accommodated in the event notification communication signal and transmitted to the management server device SV (SCVa, SVb).

More specifically, in the present embodiment, the predetermined actions are awakening, getting out of bed, falling and falling, and the sensor device SU uses the action detection processing unit 142 to detect each of these actions with a plurality of different detections. Detect with sensitivity. For example, in the detection of success or failure of wake-up, the wake-up threshold for determining success or failure of wake-up is a high-sensitivity wake-up threshold (for example, 300 cm ² ), a medium-sensitivity wake-up threshold (for example, 450 cm ² ), and a low-sensitivity wake-up threshold (for example, 600 cm ² etc.). Then, the behavior detection processing unit 142 determines whether or not the protrusion amount is equal to or higher than the high sensitivity wakeup threshold, determines whether or not the protrusion amount is equal to or higher than the medium sensitivity wakeup threshold, and It is determined whether the amount of protrusion is equal to or greater than the low sensitivity wake-up threshold. As a result of this determination, the behavior detection processing unit 142 determines that the user protrudes when the protruding amount is equal to or higher than the high sensitivity wake-up threshold, and determines that the user protrudes when the protruding amount is less than the high sensitive wake-up threshold. do not do. As a result of the determination, the behavior detection processing unit 142 determines to wake up when the amount of protrusion is equal to or greater than the medium sensitivity wake-up threshold, and determines to wake up when the amount of protrusion is less than the medium sensitivity wake-up threshold. do not do. As a result of the determination, the behavior detection processing unit 142 determines to wake up when the amount of protrusion is equal to or greater than the low sensitivity wakeup threshold, and when the amount of protrusion is less than the low sensitivity wakeup threshold, Not determined. For example, as a result of the determination of success or failure of the wake-up, the high-sensitivity wake-up threshold does not determine wake-up (0), the intermediate wake-up threshold is determined as wake-up (1), and the low-sensitivity wake-up threshold determines wake-up. When it is determined (1), the first event notification communication signal contains 011 in order from the detection result with high sensitivity as each detection result with each sensitivity. Further, for example, in the detection of success / failure of bed leaving, the bed leaving threshold for determining success / failure of bed leaving is a high sensitive bed leaving threshold (for example, 10 cm), a medium sensitive bed leaving threshold (for example, 20 cm), and a low sensitivity bed leaving threshold (for example, 30 cm). Etc.). Then, similarly to the case of success or failure of the above-described wake-up, the behavior detection processing unit 142 determines the success or failure of the getting-off using each of these three high-sensitivity leaving thresholds, medium-sensitive getting-off thresholds, and low-sensitive getting-off thresholds, Each of these determination results is accommodated in the first event notification communication signal. In addition, for example, in the detection of success or failure of a fall, the fall threshold for determining success or failure of a fall includes a high-sensitivity fall threshold (for example, 5 seconds), a medium-sensitivity fall threshold (for example, 3 cm), and a low-sensitivity fall threshold (for example, 1.5 seconds, etc.). Then, the behavior detection processing unit 142 determines the success or failure of the fall using each of these three high-sensitivity fall thresholds, medium-sensitivity fall thresholds, and low-sensitivity fall thresholds, as in the case of the above-described success or failure of the wake-up. Each of these determination results is accommodated in the first event notification communication signal. Further, for example, in the detection of success / failure of a fall, the fall threshold for determining success / failure of a fall includes a high-sensitivity fall threshold (eg, 5 seconds), a medium-sensitivity fall threshold (eg, 3 cm), and a low-sensitivity fall threshold (eg, 1.5 seconds, etc.). Then, the behavior detection processing unit 142 determines the success or failure of the fall using each of these three high-sensitivity fall threshold values, medium-sensitivity fall threshold values, and low-sensitivity fall threshold values, as in the case of the success or failure of the above-described wake-up. Each of these determination results is accommodated in the first event notification communication signal.

In the first modification, in the monitored person monitoring system MSa in the first embodiment, the management server device SVa operates as follows regarding the setting of the detection sensitivity.

In order to measure the time, the management server device SVa times the SV control processing unit 22a, and the time is up when a predetermined time (for example, 10 minutes, 30 minutes, 60 minutes, etc.) is timed. A time counter is further provided functionally, and detection sensitivity used for detecting the predetermined action is further stored in the SV storage unit 23a in association with each terminal device SP, TAa. In this example, the detection sensitivity is stored in association with any of the three high sensitivity, intermediate degree, and low sensitivity for each of the rising, leaving, falling, and falling in the predetermined action.

In FIG. 19, the management server device SVa first determines whether or not a predetermined time has elapsed by the SV control processing unit 22a (S61). More specifically, the management server device SVa determines whether or not the time counter has timed up by the SV control processing unit 22a. As a result of this determination, the SV control processing unit 22a returns the process to the process S61 when the time counter has not timed up (No), whereas when the time counter has timed up (Yes), The next process S62 is executed.

In this process S62, the management server apparatus SVa checks the number of stay notifications for each terminal apparatus SP, TAa by the SV monitoring processing section 222a of the SV control processing section 22a. More specifically, the SV monitoring processing unit 222a refers to the stay notification number information field 2332 of the first situation information table CTa stored in the situation information storage unit 233a for each of the terminal devices SP and TAa. It is determined whether or not the number of stay notifications based on the stay notification number information of the terminal devices SP and TAa is equal to or greater than a preset threshold (first sensitivity change threshold). As a result of this determination, for each of the terminal devices SP and TAa, the SV monitoring processor 222a determines that the number of stay notifications based on the stay notification number information of the terminal devices SP and TAa is not greater than or equal to the first sensitivity change threshold (No). After executing the next process S63, the process S65 is executed. On the other hand, when the number of stay notifications based on the stay notification number information of the terminal devices SP and TAa is equal to or greater than the first sensitivity change threshold (Yes), the process S65 is executed after the next process S64 is executed.

In process S63, the management server apparatus SVa changes the current detection sensitivity setting to increase the detection sensitivity for each terminal apparatus SP and TAa by the SV monitoring processing unit 222a. More specifically, the SV monitoring processing unit 222a raises the detection sensitivity of rising, leaving, falling and falling stored in the SV storage unit 23a to a level one level higher for each terminal device SP and TAa. And stored in the SV storage unit 23a. For example, when the current detection sensitivity of getting up, getting out of bed, falling, and falling in the portable terminal device TAa-1 is low, the detection sensitivity of getting up, getting out of bed, falling, and falling is changed to medium sensitivity, and SV It is stored and updated in the storage unit 23a. When the upper limit level is reached, the detection sensitivity is maintained as it is.

In process S64, the management server apparatus SVa changes the current detection sensitivity setting so as to lower the detection sensitivity for each terminal apparatus SP and TAa by the SV monitoring processing unit 222a. More specifically, the SV monitoring processing unit 222a lowers the detection sensitivities of waking up, getting out of bed, falling, and falling stored in the SV storage unit 23a to a level one level lower for each terminal device SP and TAa. And stored in the SV storage unit 23a. For example, if the current detection sensitivity of getting up, getting out of bed, falling, and falling in the portable terminal device TAa-1 is medium sensitivity, the detection sensitivity of getting up, getting out of bed, falling, and falling is changed to low sensitivity, and SV It is stored and updated in the storage unit 23a. When the lower limit level is reached, the detection sensitivity is maintained as it is.

And in process S65, in order to set the next process, management server apparatus SVa resets a time counter by SV control process part 22a, and returns a process to process S61.

By such processing, the management server device SVa in the modified form changes the detection sensitivity based on the number of stay notifications for each of the terminal devices SP and TAa at predetermined time intervals.

When the management server device SVa transmits the second event notification communication signal based on the first event notification communication signal in the process S23 shown in FIG. 10 by the SV monitoring processing unit 222a, the second event notification communication signal is transmitted. The current detection sensitivity corresponding to the transmission destination terminal devices SP and TAa is extracted from the SV storage unit 23a, and the transmission of the second event notification communication signal is controlled based on the extracted current detection sensitivity. For example, in the first event notification communication signal, if the detection result of high sensitivity is “no detection” (0) and each detection result of medium sensitivity and low sensitivity is “detection” (1), the destination terminal device If the current detection sensitivity corresponding to SP and TAa is high, the SV monitoring processing unit 222a determines that there is no detection of getting out of bed, and stops transmitting the second event notification communication signal, while the transmission destination When the current detection sensitivity corresponding to the terminal devices SP and TAa is medium sensitivity, the SV monitoring processing unit 222a determines that there is detection of getting out of bed, and transmits a second event notification communication signal. In this way, transmission of the second event notification communication signal is controlled based on the current detection sensitivity.

In the second modification, in the monitored person monitoring system MSb in the second embodiment, the management server device SVb operates as follows regarding the setting of the detection sensitivity.

In order to measure the time, the management server device SVb times the SV control processing unit 22b, and the time is up when a predetermined time (for example, 10 minutes, 30 minutes, 60 minutes, etc.) is timed. A time counter is further provided functionally, and detection sensitivity used for detecting the predetermined behavior is further stored in the SV storage unit 23b in association with each terminal device SP, TAb. In this example, the detection sensitivity is stored in association with any of the three high sensitivity, intermediate degree, and low sensitivity for each of the rising, leaving, falling, and falling in the predetermined action.

Then, in FIG. 20, the management server device SVb first determines whether or not a predetermined time has elapsed by the SV control processing unit 22b, similarly to the above-described processing S61 (S71). As a result of this determination, the SV control processing unit 22b returns the process to step S71 when the time counter has not timed up and the predetermined time has not elapsed (No), while the time counter has timed up. If the predetermined time has elapsed (Yes), the next process S72 is executed.

In this process S72, the management server apparatus SVb is stored in the second status information table CTb stored in the status information storage section 233b for each terminal apparatus SP and TAb by the SV monitoring processing section 222b of the SV control processing section 22b. With reference to the notification number information field 2334 within a predetermined period, it is determined whether the number of notifications within a predetermined period according to the notification number information within the predetermined period of the terminal device SP or TAb is equal to or greater than a preset threshold (second sensitivity change threshold). To do. As a result of this determination, for each of the terminal devices SP and TAb, the SV monitoring processing unit 222b determines that the number of notifications within the predetermined period according to the notification number information within the predetermined period of the terminal devices SP and TAb is not greater than or equal to the second sensitivity change threshold. In (No), the next process S73 is executed. On the other hand, when the number of notifications within a predetermined period according to the number of notifications within the predetermined period of the terminal device SP and TAb is equal to or greater than the second sensitivity change threshold (Yes), After executing step S74, step S76 is executed.

In the process S73, the management server apparatus SVb uses the SV monitoring processing section 222b of the SV control processing section 22b to store the predetermined information in the second situation information table CTb stored in the situation information storage section 233b for each of the terminal apparatuses SP and TAb. With reference to the in-period notification number information field 2334, it is determined whether or not the number of notifications in the predetermined period by the notification number information in the predetermined period of the terminal devices SP and TAb is equal to or less than a preset threshold (third sensitivity change threshold) . As a result of this determination, for each of the terminal devices SP and TAb, the SV monitoring processor 222b determines that the number of notifications within the predetermined period according to the number of notifications within the predetermined period of the terminal devices SP and TAb is not less than or equal to the third sensitivity change threshold. In (No), the next process S76 is performed without changing the detection sensitivity, while the number of notifications within the predetermined period according to the information on the number of notifications within the predetermined period of the terminal devices SP and TAb is equal to or greater than the third sensitivity change threshold. If there is (Yes), the process S76 is executed after the next process S75 is executed.

In process S74, the management server apparatus SVb changes the current detection sensitivity setting so as to lower the detection sensitivity for each terminal apparatus SP and TAb by the SV monitoring processing unit 222b. More specifically, the SV monitoring processing unit 222b lowers the detection sensitivity of each of the terminal devices SP and TAb, which are stored in the SV storage unit 23b, such as getting up, getting out of bed, falling, and falling down to a level one level lower. And stored in the SV storage unit 23b. For example, when the detection sensitivity of the current rising, leaving, falling, and falling in the portable terminal device TAb-1 is high, the detection sensitivity of each of rising, leaving, falling, and falling is changed to the medium sensitivity. It is stored and updated in the storage unit 23b. When the lower limit level is reached, the detection sensitivity is maintained as it is.

In process S75, the management server apparatus SVb changes the current detection sensitivity setting so as to increase the detection sensitivity for each terminal apparatus SP and TAb by the SV monitoring processing unit 222b. More specifically, the SV monitoring processing unit 222b raises the detection sensitivities of rising, leaving, falling, and falling stored in the SV storage unit 23b to a level one level higher for each terminal device SP and TAb. And stored in the SV storage unit 23b. For example, when the current detection sensitivity of getting up, getting out of bed, falling, and falling in the portable terminal device TAb-1 is medium sensitivity, the detection sensitivity of getting up, getting out of bed, falling, and falling is changed to high sensitivity, and SV It is stored and updated in the storage unit 23b. When the upper limit level is reached, the detection sensitivity is maintained as it is.

In process S76, in order to set the next process, the management server apparatus SVb resets the time counter and returns the process to process S71 by the SV control processing unit 22b.

By such processing, the management server device SVb in the second modification changes the detection sensitivity based on the number of notifications within the predetermined period for each terminal device SP, TAb at predetermined time intervals.

When the management server apparatus SVb transmits the second event notification communication signal by the first event notification communication signal in the process S23 shown in FIG. 10 by the SV monitoring processing unit 222b, the management server apparatus SVb Similarly, the current detection sensitivity corresponding to the terminal device SP, TAb that is the transmission destination of the second event notification communication signal is extracted from the SV storage unit 23b, and the second event notification communication is performed based on the extracted current detection sensitivity. Control signal transmission. In this way, transmission of the second event notification communication signal is controlled based on the current detection sensitivity.

In the first and second modified embodiments described above, the first to third sensitivity change threshold values are fixed values. In the third modified embodiment, the first and second modified embodiments so that the sensitivity change threshold value can be varied. Management server devices SVa and SVb are configured. The sensitivity change threshold is determined based on, for example, the number of terminal devices SP and TAa; SP and TAb in the monitored person monitoring systems MSa and MSb. For example, the sensitivity change threshold is set to a predetermined time (for example, midnight) set in advance for the terminal devices SP and TAa logged in the monitored person monitoring systems MSa and MSb on the previous day. It is determined based on the daily average number (terminal devices SP and TAa operating in the monitored person monitoring systems MSa and MSb on the previous day; average daily number of SP and TAb). In one example, if the daily average number of terminal devices SP, TAa; SP, TAb is 10, the sensitivity change threshold is set to 20, and the daily average number of terminal devices SP, TAa; SP, TAb is 20 When the number is the number, the sensitivity change threshold is set to 40, and when the daily average number of the terminal devices SP and TAa; SP and TAb is 5, the sensitivity change threshold is set to 10. Further, for example, the sensitivity change threshold is set by logging in to the monitored person monitoring systems MSa and MSb in the nighttime period of the previous day at the time of switching from the daytime period to the nighttime period (for example, 8:00 pm). Terminal device SP, TAa; determined based on the average number of SP, TAb at night time zone, and at the time of switching from a preset night time zone to daytime zone (for example, 8:00 am, etc.) Is determined based on the average number of daytime time zones of the terminal devices SP and TAa; SP and TAb logged in the monitored person monitoring systems MSa and MSb in the daytime zone. In addition, for example, the sensitivity change threshold is the terminal device SP logged in to the monitored person monitoring systems MSa and MSb during the previous period every predetermined period (for example, 10 minutes, 30 minutes, 60 minutes, etc.). , TAa; determined based on the average number of SP and TAb.

As an example, the case where the sensitivity change threshold value is dynamically changed every predetermined period in the second modification will be described in more detail below. The first modification can be described in the same manner as described below.

In this example, in FIG. 21, the management server device SVb first determines whether or not a predetermined time has passed by the SV control processing unit 22b, similarly to the above-described processing S61 (S81). As a result of this determination, the SV control processing unit 22b returns the process to step S81 when the time counter has not timed up and the predetermined time has not elapsed (No), while the time counter has timed up. If the predetermined time has elapsed (Yes), the next process S82 is executed.

In this process S82, the management server apparatus SVb determines whether or not the number of the operating terminal apparatuses SP and TAb has changed compared to the previous determination by the SV control processing unit 22b. That is, the SV control processing unit 22b determines whether or not the number of logged-in terminal devices SP and TAb has changed compared to the previous determination axis.

In (No), the next process S88 is executed without changing the detection sensitivity. On the other hand, the number of notifications within the predetermined period according to the notification number information within the predetermined period of the terminal device SP, TAb is equal to or greater than the fifth sensitivity change threshold. If there is (Yes), the process S88 is executed after the next process S87 is executed.

In process S86, the management server apparatus SVb changes the current detection sensitivity setting so as to lower the detection sensitivity for each terminal apparatus SP and TAb by the SV monitoring processing unit 222b. More specifically, the SV monitoring processing unit 222b lowers the detection sensitivity of each of the terminal devices SP and TAb, which are stored in the SV storage unit 23b, such as getting up, getting out of bed, falling, and falling down to a level one level lower. And stored in the SV storage unit 23b.

In process S87, the management server apparatus SVb changes the current detection sensitivity setting to increase the detection sensitivity for each terminal apparatus SP and TAb by the SV monitoring processing unit 222b. More specifically, the SV monitoring processing unit 222b raises the detection sensitivities of rising, leaving, falling, and falling stored in the SV storage unit 23b to a level one level higher for each terminal device SP and TAb. And stored in the SV storage unit 23b.

And in process S88, in order to set the next process, management server apparatus SVb resets a time counter by SV control process part 22b, and returns a process to process S81.

By such processing, the management server device SVb in the third modified embodiment changes the detection sensitivity based on the number of notifications within the predetermined period for each terminal device SP, TAb at predetermined time intervals.
