Description

The present invention relates to a monitored person monitoring device and a monitored person monitoring method for monitoring a monitored person to be monitored, and a monitored person monitoring support system using the same.

In an aging society like Japan (Japan), the nurses and long-term care recipients who need nursing care due to illness, injury, or aging are the nurses who need nursing care in a normal society that is not an aging society. The number is expected to increase more than those requiring long-term care. These nurses and long-term care recipients generally enter hospitals and facilities such as welfare facilities for the elderly (short-term admission facilities for the elderly, nursing homes for the elderly, special nursing homes for the elderly, etc. under Japanese law). Receive nursing and long-term care. In such facilities, nurses, caregivers, etc. regularly patrol to confirm their safety and condition. In terms of this safety confirmation, a single person living alone is the same as the above-mentioned nurse-requiring person or long-term care-requiring person. On the other hand, in recent years, home medical care such as home-visit medical care and home visits has been requested for those who have difficulty in moving alone or who wish to receive medical treatment at home.

In such an industry, the increase in the number of people who provide the services (service providers) cannot keep up with the increase in the number of people who request services such as medical care, nursing, and long-term care (service beneficiaries), and it is chronically manpowered. There is a shortage. Therefore, in order to reduce the burden of the service and the work generated in connection with the service, there is a demand for a technique for complementing the service and the work. As one of such techniques, an image recording apparatus disclosed in Patent Document 1 has been proposed.

As one of such techniques, for example, there is a nurse call system disclosed in Patent Document 1. The nurse call system disclosed in Patent Document 1 is installed in a bed for a patient to call a nurse, and is installed in a nurse station for answering a call by the nurse call slave unit. A nurse call system having a nurse call master unit, in which a camera that captures a patient on the bed from above the bed and a state in which the patient is upright and the patient is away from the bed from the images captured by the camera. The nurse call master unit has a state determining means for determining the occurrence of at least one of them and outputting an attention state generation signal, and the nurse call master unit has a notification means for receiving the attention state generation signal and performing a notification operation. Then, this nurse call system receives the mobile terminal carried by the nurse to answer the call from the nurse call slave unit and the caution state generation signal, and transmits the captured image of the camera to the mobile terminal. It has a communication control means to be used.

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

By the way, in such a system that detects and notifies (notifies, issues) a predetermined action (physical condition) in the monitored person, the predetermined action that actually occurs when the detection condition is strictly set. There is a risk that a false report may occur that cannot be detected and is not notified. When a misreport occurs, not only is the predetermined action actually occurring not notified, but the predetermined action that has occurred to the monitored person may develop into a more serious situation, which is preferable. not. On the other hand, if the detection condition is loosely set, there is a possibility that a false alarm may occur in which the predetermined action that has not actually occurred is erroneously detected and notified instead of the false alarm. When the predetermined action is notified, the observer often takes measures such as going to the site of the notified person to be monitored, but if the notification is a false alarm, the observer takes measures. It becomes a waste and a loss of labor. Therefore, a device capable of reducing false alarms and false alarms having such a trade-off relationship is desired.

Japanese Unexamined Patent Publication No. 2014-90913

This Doppler sensor is a body motion sensor that transmits a transmitted wave, receives the reflected wave of the transmitted wave reflected by an object, and outputs a Doppler signal of a Doppler frequency component based on the transmitted wave and the reflected wave. .. When the object is moving, the frequency of the reflected wave shifts in proportion to the moving speed of the object due to the so-called Doppler effect, so there is a difference (Doppler frequency component) between the frequency of the transmitted wave and the frequency of the reflected wave. Occurs. The Doppler sensor generates a signal of this Doppler frequency component as a Doppler signal and outputs it to the SU control processing unit 14. The transmitted wave may be an ultrasonic wave, a microwave, or the like, but in the present embodiment, it is a microwave. Since the microwave can pass through the clothes and be reflected on the body surface of the monitored person Ob, the movement of the body surface can be detected even if the monitored person Ob is wearing clothes, which is preferable.

The various predetermined programs include, for example, a SU control program that controls each part of the sensor device SU according to the function of each part, and a predetermined action in the monitored person Ob based on the output of the sensor part 11. Then, depending on the detection conditions used at the time of the detection, the management server device SV is directly notified, or the authenticity determination terminal device JT is indirectly notified to the management server device SV, and the detection is performed. Depending on the detection conditions used at the time of the detection, a moving image (event moving image) of a predetermined time length related to a predetermined action is sent only to the management server device SV, or the management server device SV and the authenticity determination terminal device JT. The behavior detection processing program to be transmitted to each, and when the nurse call reception operation unit 13 receives the nurse call, the management server device SV is notified to that effect, and the SU sound input / output unit 12 or the like is used to notify the terminal device SP. , A nurse call processing program that makes a voice call with TA, and SU streaming processing that distributes the moving image generated by the imaging unit 111 to the terminal device SP, TA, and the authenticity determination terminal device JT that requested the moving image. A control processing program such as a program is included. The various predetermined data include the sensor device identifier (sensor ID), which is an identifier for identifying and identifying the sensor device SU, the communication address of the management server device SV, and the authenticity determination terminal device JT. It contains data necessary for executing each program such as the communication address of. The SU storage unit 16 includes, for example, a ROM (Read Only Memory) which is a non-volatile storage element, an EEPROM (Electrically Erasable Programmable Read Only Memory) which is a rewritable non-volatile storage element, and the like. The SU storage unit 16 includes a RAM (Random Access Memory) or the like that serves as a working memory of the so-called SU control processing unit 14 that stores data or the like generated during the execution of the predetermined program.

Then, in the present embodiment, when the action detection processing unit 142 detects the predetermined action, the SU storage unit 16 stores the moving image (event movie) having a predetermined time length before and after the detection. A sensor-side moving image storage unit (SU moving image storage unit) 161 is functionally provided. The SU moving image storage unit 161 is a ring buffer for storing moving images of a predetermined time length. The predetermined time length is, for example, several minutes such as one minute, one and a half minutes, two minutes and three minutes. In consideration of the processing time required for the process of transferring the moving image stored in the SU moving image storage unit 161 to the management server device SV, the SU moving image storage unit 161 adds a margin of, for example, several seconds to the predetermined time length. It may be configured with a storage capacity capable of storing a moving image.

The SU control processing unit 14 controls each unit of the sensor device SU according to the function of each unit, detects a predetermined event (event) related to the monitored person Ob, and sets the detection condition used at the time of the detection. Correspondingly, it notifies the management server device SV directly or indirectly to the management server device SV via the authenticity determination terminal device JT, and a moving image of a predetermined time length related to the detected predetermined action ( The event video) is transmitted to the management server device SV only or to the management server device SV and the authenticity determination terminal device JT, respectively, depending on the detection conditions used at the time of the detection, and the terminal devices SP and TA are transmitted. It is a circuit for making a voice call between the two, generating an image including a moving image, and distributing the moving image to the terminal device SP, TA, and the authenticity determination terminal device JT. In the present embodiment, the SU control processing unit 14 stores the moving image generated by the imaging unit 111 of the sensor unit 11 in the SU moving image storage unit 161. The SU control processing unit 14 is configured to include, for example, a CPU (Central Processing Unit) and peripheral circuits thereof. When the control processing program is executed, the SU control processing unit 14 has a sensor side control unit (SU control unit) 141, an action detection processing unit 142, a nurse call processing unit (nurse call processing unit) 143, and a sensor side streaming.

In the present embodiment, the SU control unit 141 stores the moving image generated by the imaging unit 111 of the sensor unit 11 in the SU moving image storage unit 161 of the SU storage unit 16. More specifically, the SU control unit 141 sequentially stores the moving image generated by the imaging unit 111 from the beginning to the end of the storage area allocated as the SU moving image storage unit 161 of the SU storage unit 16. When the end of the storage area is reached, the process returns to the beginning of the storage area, and similarly, the moving image generated by the imaging unit 111 is sequentially stored (stored by overwriting) from the beginning to the end of the storage area. , And so on. As a result, the SU moving image storage unit 161 stores the past moving images for the predetermined time length from the present time.

The action detection processing unit 142 detects a predetermined predetermined action in the monitored person Ob based on the output of the sensor unit 11 and notifies the management server device SV. The action detection processing unit 142 detects the same type of action in the predetermined action under a plurality of detection conditions including at least different first and second detection conditions set for the same type of action. When the action is detected under the first detection condition by this detection, the action detection processing unit 142 notifies the management server device SV, which is the first device of the first notification destination, of the detection of the action, and the detection. When the action is detected under the second detection condition, the moving image generated by the action detection and the image pickup unit 111 is different from the management server device SV which is the first device of the first notification destination. 2 Notify the authenticity determination terminal device JT, which is the second device of the notification destination.

In the present embodiment, the sensor unit 11 and the action detection processing unit 142 perform the same type of action under a plurality of detection conditions including at least different first and second detection conditions set for the same type of action. It corresponds to an example of a detection unit for detection. When the behavior is detected by the detection unit under the first detection condition, the behavior detection processing unit 142 notifies the first device of the first notification destination of the detection of the behavior, and the detection unit notifies the second device. When the action is detected under the detection conditions, the notification that the action is detected and the moving image generated by the imaging unit is notified to the second device of the second notification destination different from the first device of the first notification destination. It also corresponds to an example of a control unit.

More specifically, in the present embodiment, the predetermined behavior is getting up, getting out of bed, falling, and stopping body movement as described above. These getting up, getting out of bed, and falling are detected based on the output (target image) of the imaging unit 111, and the body movement stop is detected based on the output (Doppler signal) of the body movement measuring unit 112.

More specifically, the behavior detection processing unit 142 may, for example, base the monitored person Ob based on the amount of protrusion of the bedding area in the target image captured by the imaging unit 11 from the pre-stored location area of the bedding. Wake-up is detected at two levels: probable wake-up and possible wake-up. The highly probable wake-up means a case where the event is detected under the relatively strict first detection condition and the event generated in the monitored person Ob is truly wake-up. The possibility of waking up means a case where the waking up is detected under a relatively loose second detection condition, the event generated in the monitored person Ob may be waking up, and the waking up is suspected. In order to detect wake-up at two levels, first, a threshold value for determining possible wake-up from the location area of the bedding BT and the amount of protrusion (wake-up suspicion determination threshold value, second detection condition (second A)). An example of the detection condition)) and a threshold value for determining wake-up with a high probability from the amount of protrusion (wake-up determination threshold value, an example of the first detection condition (first A detection condition)) are 1 of the various predetermined data. As a result, the SU storage unit 16 is stored in advance. The wake-up suspicion determination threshold value and the wake-up determination threshold value are appropriately set in advance using a plurality of samples. The wake-up determination threshold is used to determine the probability of wake-up, while the wake-up suspicion determination threshold is used to determine the possibility of wake-up. Therefore, the wake-up suspicion determination threshold is higher than the wake-up determination threshold. Set to a small value. As a result, while waking up is detected with a relatively high probability, cases where waking up is suspected can also be detected. Waking up may be detected at each level in multiple stages by further increasing the threshold value. Then, the behavior detection processing unit 142 obtains the bedding region in the target image from the target image by, for example, the background subtraction method. Next, the behavior detection processing unit 142 obtains the amount of protrusion by subtracting the pre-stored location area of the bedding from the bedding area in the obtained target image. Next, the behavior detection processing unit 142 compares the obtained amount of protrusion with each of the wake-up suspicion determination threshold value and the wake-up determination threshold value. As a result of this comparison, when the obtained protrusion amount is less than the wake-up suspicion determination threshold value, the behavior detection processing unit 142 determines that the wake-up is neither possible nor highly probable, and the wake-up suspicion determination threshold is determined. When the amount is equal to or greater than the wake-up suspicion determination threshold value and less than the wake-up determination threshold value, the behavior detection processing unit 142 determines that the wake-up is possible, detects the possible wake-up, and obtains the above-mentioned determination. When the amount of protrusion is equal to or greater than the wake-up determination threshold value, the behavior detection processing unit 142 determines that the wake-up is highly probable, and detects the wake-up with a high probability. The wake-up suspicion determination threshold value may be 0. In this case, if even a slight amount of protrusion is obtained from the target image, it is determined that the wake-up is possible, and the possible wake-up is detected.

Further, for example, the behavior detection processing unit 142 has a high probability that the monitored person Ob will leave the bed based on the amount of overlap between the pre-stored bedding location area and the human body area in the target image captured by the image pickup unit 11. Detect at two levels: getting out of bed and possibly getting out of bed. The highly probable getting out of bed means a case where the event generated in the monitored person Ob is detected under the relatively strict first detection condition, and it is highly probable that the event occurs in the monitored person Ob. The possibility of getting out of bed means a case where the event that occurs in the monitored person Ob is likely to get out of bed and is suspected to get out of bed, because it is detected under a relatively loose second detection condition. In order to detect getting out of bed at two levels in this way, first, more specifically, the area where the bedding BT is located, and the threshold value for determining possible getting out of bed from the overlap (threshold value for determining suspicion of getting out of bed, second detection condition). (An example of the second B detection condition)) and a threshold value for determining a highly probable bed leaving from the overlap amount (an example of a bed leaving determination threshold and a first detection condition (first B detection condition)) are various predetermined values. The SU storage unit 16 is stored in advance as one of the data. The suspicion of getting out of bed and the threshold of getting out of bed are appropriately set in advance using a plurality of samples. Since the bed leaving determination threshold value is used to determine the probability of getting out of bed, while the bed leaving suspicion determination threshold value is used to determine the possibility of getting out of bed, the bed leaving determination threshold value is higher than the bed leaving suspicion determination threshold value. Set to a small value. As a result, while getting out of bed is detected with a relatively high probability, it is possible to detect cases in which it is suspected to get out of bed. By further increasing the threshold value, getting out of bed may be detected at each level in multiple stages. Then, the behavior detection processing unit 142 extracts a moving object region from the target image as a human body region of the monitored person Ob by, for example, a background subtraction method or a frame subtraction method. Next, the behavior detection processing unit 142 obtains the amount of overlap between the human body region (moving body region) in the obtained target image and the pre-stored bedding location region. Next, the behavior detection processing unit 142 compares the obtained overlap amount with the bed leaving suspicion determination threshold value and the bed leaving determination threshold value, respectively. As a result of this comparison, when the obtained overlap amount is larger than the suspicion of getting out of bed determination threshold value, the behavior detection processing unit 142 determines that it is neither a possible getting out of bed nor a highly probable getting out of bed, and the obtained overlapping amount When is equal to or less than the suspicion of getting out of bed and is larger than the threshold of suspicion of getting out of bed, the behavior detection processing unit 142 determines that the person is likely to get out of bed, detects the possibility of getting out of bed, and obtains the overlap. When the amount is equal to or less than the threshold for leaving the bed, the behavior detection processing unit 142 determines that the person has a high probability of leaving the bed, and detects the high probability of leaving the bed. The threshold for determining getting out of bed may be 0. In this case, when the amount of overlap in the target image disappears, it is determined that the patient has a high probability of getting out of bed, and the high probability of getting out of bed is detected.

Further, for example, the behavior detection processing unit 142 is a region excluding the pre-stored bedding location region, and the monitored person is monitored based on the speed at which the size of the monitored person Ob in the head changes (the speed of change of the head). Ob falls are detected at two levels: probable falls and possible falls. The highly probable fall means that the event is detected under the relatively severe first detection condition and the event generated in the monitored person Ob is highly probable to be a true fall. The possible fall means a case where the fall is detected under a relatively loose second detection condition, the event generated in the monitored person Ob may be a fall, and the fall is suspected. In order to detect a fall at two levels, first, a threshold value for determining a possible fall from the location area of the bedding BT and the change speed of the head (fall suspicion determination threshold value, second detection condition). (Example of the second C detection condition)), and the threshold value for determining a highly probable fall from the change speed of the head (a fall determination threshold, an example of the first detection condition (first C detection condition)) are various. The SU storage unit 16 is stored in advance as one of the predetermined data of the above. The fall suspicion determination threshold value and the fall determination threshold value are appropriately set in advance using a plurality of samples. The fall determination threshold is used to determine the probability of a fall, while the fall suspicion determination threshold is used to determine the possibility of a fall. Therefore, the fall determination threshold is higher than the fall suspicion determination threshold. Set to a large value. As a result, while a fall is detected with a relatively high probability, a case in which a fall is suspected can also be detected. In addition, the fall may be detected at each level of multiple stages by further increasing the threshold value. Then, the behavior detection processing unit 142 extracts a moving object region from the target image as a human body region of the monitored person Ob by, for example, a background subtraction method or a frame subtraction method. Next, the behavior detection processing unit 142 uses the extracted moving body region, for example, by a circular or elliptical Hough transform, for example, by pattern matching using a pre-prepared head model, or for example, for head detection. The head region of the monitored person Ob is extracted by the neural network learned in. Next, the behavior detection processing unit 142 obtains the change speed of the head from the extracted head region and the head region extracted in the previous detection processing. In addition, from the change in the size of each head region extracted by each detection process from the size of the head in the standing posture to the size of the head in the lying down posture, the head The rate of change may be determined. Next, the behavior detection processing unit 142 compares the obtained change speed of the head with the fall suspicion determination threshold value and the fall determination threshold value, respectively. As a result of this comparison, when the obtained change rate of the head is smaller than the above-mentioned fall suspicion determination threshold, the behavior detection processing unit 142 determines that neither a possible fall nor a highly probable fall is made, and the above-mentioned determination is made. When the rate of change of the head is equal to or higher than the fall suspicion determination threshold and is less than the fall determination threshold, the behavior detection processing unit 142 determines that the fall is possible and causes the possible fall. When it is detected and the obtained change speed of the head is equal to or higher than the fall determination threshold value, the behavior detection processing unit 142 determines that the fall has a high probability and detects the fall with a high probability.

Then, the behavior detection processing unit 142 detects the body movement stop of the monitored person Ob based on the output of the body movement measurement unit 112 at two levels of a highly probable body movement stop and a possible body movement stop. do. The highly probable body movement stop means a case where the body movement stop is detected under a relatively severe first detection condition and the event generated in the monitored person Ob is truly a body movement stop. The possibility of body stoppage means a case where the body movement stop is detected under a relatively loose second detection condition, the event generated in the monitored person Ob may be body movement stoppage, and the body movement stoppage is suspected. .. In order to detect the body movement stop at the two-step level, first, more specifically, it is determined from the output of the body movement measuring unit 112 whether or not there is a movement of the body surface of the chest (up and down movement of the chest) accompanying the breathing movement. (Body surface movement determination threshold), a threshold for determining possible body movement stop from the duration of no movement of the body surface (body movement stop suspicion determination threshold), and the body surface. The SU storage unit 16 stores in advance a threshold value (body movement stop determination threshold) for determining body movement stop with a high probability of body movement from the duration of no movement. The body movement stop suspicion determination threshold value and the body movement stop determination threshold value are appropriately set in advance using a plurality of samples. The body movement stop determination threshold value is used to determine the probability of body movement stop, while the body movement stop suspicion determination threshold value is used to determine the possibility of body movement stop, and thus the body movement stop. The determination threshold value is set to a value larger than the body movement stop suspicion determination threshold value. As a result, while the body movement stop is detected with a relatively high probability, the case where the body movement stop is suspected can also be detected. By further increasing the threshold value, body movement stop may be detected at each level of multiple stages. Then, the behavior detection processing unit 142 compares the output of the body movement measuring unit 112 with the body surface movement determination threshold value. As a result of this comparison, when the output of the body movement measuring unit 112 is larger than the body surface movement determination threshold value, the behavior detection processing unit 142 determines that there is movement of the body surface, and outputs the body movement measuring unit 112. When is equal to or less than the body surface movement determination threshold value, the behavior detection processing unit 142 determines that there is no movement of the body surface, and refers to the determination result determined in the previous detection process to obtain the body surface. Find the duration for which it has been determined that there is no movement. Next, the behavior detection processing unit 142 compares the obtained duration with each of the body movement stop suspicion determination threshold value and the body movement stop determination threshold value. As a result of this comparison, when the obtained duration is smaller (shorter) than the body movement stop suspicion determination threshold, the behavior detection processing unit 142 is neither a possible body movement stop nor a probable body movement stop. If the obtained duration is equal to or greater than the body movement stop suspicion determination threshold and is less than the body movement stop determination threshold, the behavior detection processing unit 142 determines that the body movement stop is possible. Then, when the possible body movement stop is detected and the obtained duration is equal to or longer than the body movement stop determination threshold value, the behavior detection processing unit 142 determines that the body movement stop is highly probable. The highly probable body movement stop is detected.

When the predetermined behavior is detected under the first detection condition (first A, first B, first C, and first D detection condition) in this way, the behavior detection processing unit 142 performs a predetermined event (event) related to the monitored person Ob. The SU communication IF unit 15 notifies the management server device SV of a communication signal (first event notification communication signal) for notifying the event, which contains event information (event information) representing the contents of. More specifically, the action detection processing unit 142 transmits the sensor ID of the own machine, the event information representing the content of the event, and the first event notification communication signal containing the target image used when detecting the predetermined action. , Transmits to the management server device SV via the SU communication IF unit 15.

One or more of the movement stop, getting up, getting out of bed, and falling are accommodated in the first event notification communication signal as the event information. Then, when the predetermined action is detected under the first detection condition, the action detection processing unit 142 has the sensor ID of the own machine, the event information indicating the content of the event, and the predetermined time length before and after the detection of the event. The communication signal (event video notification communication signal) accommodating the event video is transmitted to the management server device SV via the SU communication IF unit 15.

On the other hand, when the predetermined action is detected under the second detection conditions (second A, second B, second C, and second D detection condition) in this way, the action detection processing unit 142 determines the authenticity of the detected event. The SU communication IF unit 15 notifies the authenticity determination terminal device JT of the communication signal (authenticity determination request notification communication signal) for requesting. More specifically, the behavior detection processing unit 142 has information indicating a request for authenticity determination for the detected event (authenticity determination request information), its own sensor ID, and event information indicating the content of the event (possibility).

In the present embodiment, the first action is getting up, getting out of bed, and falling, and each of these is the first detection condition (in the present embodiment, the suspicion of getting up, the suspicion of getting out of bed, and the suspicion of falling). And the second detection condition (in this embodiment, the wake-up determination threshold value, the wake-up determination threshold value, and the fall determination threshold value) are used to detect each of the two levels. That is, the behavior detection processing unit 142 determines the success or failure of wake-up at each level of possible wake-up and probable wake-up, and determines the success or failure of wake-up at each level of possible wake-up and probable wake-up. Judgment is made, and the success or failure of each level of a fall that is likely to fall and a fall that is likely to fall is judged.

Next, the sensor device SU acquires the output of the body motion measuring unit 112 of the sensor unit 11 by the SU control unit 141 of the SU control processing unit 14 (S12).

Next, the sensor device SU detects the second action that can be detected based on the output of the body motion measuring unit 112 among the predetermined actions in the monitored person Ob by the action detecting processing unit 142 of the SU control processing unit 14. The second action detection process is executed based on the output of the body motion measuring unit 112 acquired in the process S12, and the second detection result is stored in the SU storage unit 16 (S13). In the present embodiment, the second action is body movement stop, and the action detection processing unit 142 determines the body movement stop as the first detection condition (in the present embodiment, the body movement stop suspicion determination threshold value) and the second detection. By using each of the conditions (the above-mentioned body movement stop determination threshold in the present embodiment), the success or failure is determined at each of the two levels of possible body movement stop and highly probable body movement stop.

Next, the sensor device SU is the predetermined predetermined in the monitored person Ob based on the first detection result and the second detection result stored in the SU storage unit 16 in the processing S11 and the processing S13 by the behavior detection processing unit 142. Whether or not an action is detected is determined at each level of the above two stages (S14). As a result of this determination, when the predetermined action is not detected (No), the sensor device SU then executes the process S19, while the predetermined action is detected under the first detection condition. If (that is, at least one of probable getting up, getting out of bed, falling, and stopping movement is detected) (first detection condition), the sensor device SU sequentially performs the following processes S15 and S16. Then, the process S19 is executed, and on the other hand, when the predetermined behavior is detected under the second detection condition (that is, at least one of possible getting up, getting out of bed, falling, and stopping movement). When detected) (second detection condition), the sensor device SU sequentially executes the next processes S17 and S18, and then executes the process S19.

In this process S15, the sensor device SU executes the first preparatory process for transmitting the event video of a predetermined time length before and after the detection of the predetermined action to the management server device SV by the action detection processing unit 142. .. More specifically, the action detection processing unit 142 manages the detected predetermined action and the transmission destination by setting a timer set by a preset time length of the moving image, which is required after the detection of the predetermined action. It is generated in association with the server device SV (server ID, communication address of the management server device SV), and the generated timer is started (see process S151 in FIG. 8). For example, the SU moving image storage unit 161 stores a moving image of about two and a half minutes (about two minutes and 30 seconds), and the moving image is about 30 seconds before the detection of the predetermined action and about two minutes after the detection of the predetermined action. When an event video of about two and a half minutes consisting of a video is generated, a timer that time-ups in two minutes is generated and started. Further, for example, when the SU video storage unit 161 stores a video of about 3 minutes and an event video of about 3 minutes consisting of each video of about 1 and a half minutes before and after the detection of the predetermined action is generated, 1 minute. A timer that times up in half is generated and started. Further, for example, the SU moving image storage unit 161 stores a moving image of about 2 minutes, and is composed of a moving image of about 30 seconds before the detection of the predetermined action and a moving image of about 1 and a half minutes after the detection of the predetermined action. When a minute event video is generated, a timer that times up in one and a half minutes is generated and started.

Next to this process S15, in order to notify the predetermined terminal device SP and TA of the detected predetermined action via the management server device SV, the sensor device SU is subjected to the predetermined action detection processing unit 142. As an event, the first event notification communication signal related to the detection of the predetermined action is transmitted to the management server device SV (S16), and then the process S19 is executed. More specifically, the behavior detection processing unit 142 includes the sensor ID of the own machine, event information (here, one or more of getting up, getting out of bed, falling and stopping body movement), and the first event notification containing the target image. The communication signal is transmitted to the management server device SV via the SU communication IF unit 15.

On the other hand, in the process S17, the sensor device SU transmits the event video of a predetermined time length before and after the detection of the predetermined action to the management server device SV and the authenticity determination terminal device JT, respectively, by the action detection processing unit 142. The second preparatory process is executed. More specifically, the action detection processing unit 142 manages the detected predetermined action and the transmission destination by setting a timer set by a preset time length of the moving image, which is required after the detection of the predetermined action. Corresponding to the server device SV (server ID, communication address of the management server device SV) and the authenticity determination terminal device JT (identifier of the authenticity determination terminal device (judgment terminal ID), communication address of the authenticity determination terminal device JT) It is generated, generated in association with the detected predetermined action, and the generated timer is started (see process S171 in FIG. 8).

Next to this process S17, in order to notify the authenticity determination terminal device JT of the detected predetermined action and request the authenticity of the detected predetermined action, the sensor device SU is a behavior detection processing unit. By 142, the authenticity determination request notification communication signal regarding the detection of the predetermined action is transmitted to the authenticity determination terminal device JT as the predetermined event, and the data necessary for transmitting the second event notification communication signal is transmitted to the SU storage unit 16. Is temporarily stored in (S18), and then the process S19 is executed. More specifically, the behavior detection processing unit 142 performs authenticity determination request information, sensor ID of the own machine, event information (here, one or more of getting up, getting out of bed, falling and stopping body movement), and live. The authenticity determination request notification communication signal accommodating the communication address of the own machine as the acquisition destination of the moving image is transmitted to the authenticity determination terminal device JT via the SU communication IF unit 15. Then, the action detection processing unit 142 stores the event information representing the detected predetermined action and the target image used when detecting the predetermined action, which are accommodated in the second event notification communication signal, in SU. Temporarily stored in part 16.

In the process S19, the sensor device SU determines whether or not the nurse call is accepted by the nurse call processing unit 143. That is, the processes S10 to S20 shown in FIG. 7 are repeatedly executed every frame or every few frames, but the nurse is executed between the previous execution of the process S19 and the current execution of the process S19. It is determined whether or not the call reception operation unit 13 has been operated. As a result of this determination, if the nurse call reception operation unit 13 is not operated and the nurse call is not accepted (No), the sensor device SU ends the present processing, while the nurse call reception operation unit 13 is not operated. Is operated and the nurse call is accepted (Yes), the sensor device SU ends the current process after executing the next process S20.

In this process S20, in order to notify the predetermined terminal device SP and TA of the nurse call whose reception is found in the process S19 via the management server device SV, the sensor device SU is described by the nurse call processing unit 143. The first event notification communication signal related to the nurse call is transmitted to the management server device SV as the event of. More specifically, the nurse call processing unit 143 manages the first event notification communication signal accommodating the sensor ID of the own machine and the event information (here, the nurse call reception information) via the SU communication IF unit 15. Send to the device SV.

On the other hand, to explain the operation related to the timer generated in the process S15, as described above, in FIG. 8, the action detection processing unit 142 has a preset moving time time required after the detection of the predetermined action. When the timer is set and started by the length (S151), the action detection processing unit 142 determines whether or not the timer has timed up (S152). As a result of this determination, when the timer has not timed up (No), the action detection processing unit 142 returns the processing to the processing S152, while when the timer has timed up as a result of the determination (Yes). The action detection processing unit 142 generates an event video (event video file) in which the video stored in the SU video storage unit 161 is used as one video file (S153). Next, the action detection processing unit 142 receives the sensor ID of its own machine, the predetermined action detected in association with the timer as the event information, and the event video notification communication accommodating the generated event video. A signal is generated to the management server device SV of the transmission destination associated with the timer, the generated event video notification communication signal is transmitted to the management server device SV, and this process is terminated. The action detection processing unit 142 processes each of these processes S151 to S154 in parallel with the above-mentioned processes S10 to S20 described with reference to FIG. 7.

Then, to explain the operation related to the timer generated in the process S17, as described above, in FIG. 8, the action detection processing unit 142 has a preset moving time time required after the detection of the predetermined action. When the timer is set and started by the length (S171), the action detection processing unit 142 determines whether or not the timer has timed up (S172). As a result of this determination, if the timer has not timed up (No), the action detection processing unit 142 returns the process to the process S172, while the timer has timed up as a result of the determination (Yes). The action detection processing unit 142 generates an event moving image (event moving image file) in which the moving image stored in the SU moving image storage unit 161 is used as one moving image file (S173). Next, the action detection processing unit 142 receives the sensor ID of the own machine, the predetermined action detected in association with the timer as the event information, and the event video notification communication accommodating the generated event video. A signal is generated to the management server device SV and the authenticity determination terminal device JT of the destination associated with the timer, and the generated event video notification communication signal is sent to the management server device SV and the authenticity determination terminal device JT, respectively. It is transmitted by multicast and this process is terminated. The action detection processing unit 142 processes each of these processes S171 to S174 in parallel with the above-mentioned processes S10 to S20 described with reference to FIG. 7.

On the other hand, an operation related to receiving a reply to the authenticity determination request notification communication signal transmitted in the process S18 will be described.

First, the authenticity determination terminal device JT that has received the authenticity determination request notification communication signal transmitted from the sensor device SU in the process S18 is the acquisition destination of the live video accommodated in the received authenticity determination request notification signal. A communication signal (live video request communication signal) for requesting live video distribution using the communication address of is transmitted to the sensor device SU, and when the video is delivered by streaming from the sensor device SU, the video is played live. indicate. Further, when the authenticity determination terminal device JT receives the event video notification communication signal transmitted from the sensor device SU in the process S174, the event video notification communication signal accommodated in the received event video notification communication signal is displayed. The user (authenticity determination person, operator) of the authenticity determination terminal device JT determines the authenticity of the occurrence of the predetermined action by referring to the live video (live video) or the event video (the predetermined accuracy determination person). (It is determined whether or not an action has occurred), and whether or not the notification of the detection of the predetermined action is necessary is input to the authenticity determination terminal device JT. When the input requiring notification is received, the authenticity determination terminal device sends a communication signal (notification necessary notification communication signal) for notifying the sensor device SU of an instruction requiring notification, of the authenticity determination request notification signal. Reply to the sensor device SU of the sender. The notification-required notification communication signal contains instructions (commands, commands) that require notification, as well as sensor IDs and event information contained in the authenticity determination request notification signal. On the other hand, when an input that does not require notification is received, the authenticity determination terminal device sends a communication signal (notification unnecessary notification communication signal) for notifying the sensor device SU of an instruction that does not require notification, for authenticity determination request notification communication. Reply to the sensor device SU that is the sender of the issue. The notification-free notification communication signal includes instructions (commands, commands) that do not require notification, and sensor IDs and event information contained in the authenticity determination request notification signal.

When the authenticity determination terminal device JT is operating in this way, in FIG. 9, the sensor device SU first receives a communication signal from the SU communication IF unit 15 by the SU control unit 141 of the SU control processing unit 14. It is determined whether or not it has been done (S21). As a result of this determination, if the communication signal is not received (No), the sensor device SU returns the process to S21, and if the result of the determination is that the communication signal is received (Yes), the sensor device SU returns the process. The device SU executes the next process S22. That is, the sensor device SU is waiting for the reception of the communication signal.

In the process S22, the sensor device SU determines the type of the received communication signal by the SU control unit 141. As a result of this determination, when the received communication signal is the notification required notification communication signal (notification required notification), the sensor device SU executes the process S26 after executing the process S23, and the received communication signal is the received communication signal. In the case of a notification-free notification communication signal (notification-free notification), the processing S26 is executed after the processing S24 is executed, and the received communication signal is not the notification-required notification communication signal and the notification-free notification communication signal. (Other), the process S26 is executed after the process S25 is executed.

In the process S23, the sensor device SU manages the second event notification communication signal according to the notification required communication signal received from the authenticity determination terminal device JT in the process S21 by the action detection processing unit 142 of the SU control processing unit 14.

More specifically, the behavior detection processing unit 142 stores the event information and the target image temporarily stored in the SU storage unit 16 in the processing S18 in the sensor ID of the own machine and the SU storage unit 16. The second event notification communication signal containing the event information (here, one or more of getting up, getting out of bed, falling, and stopping movement) and the target image is sent to the management server device SV via the SU communication IF unit 15. Send. As a result, the detection result detected as an action that may have been detected under the second detection condition is notified as a correct detection, and the misreporting can be reduced.

In the process S24, the sensor device SU temporarily enters the SU storage unit 16 in response to the notification-free communication signal received from the authenticity determination terminal device JT in the process S21 by the action detection process unit 142 of the SU control process unit 14. Delete the stored event information and target image. As a result, the detection result detected as an action that may have been detected under the second detection condition is deleted as an erroneous detection, and false alarms can be reduced.

In the process S25, the sensor device SU executes an appropriate process according to the communication signal received in the process S21 by the SU control process unit 14.

Then, in the process S26 executed after each of the processes S23 to S25, the sensor device SU determines whether or not its operation is terminated (stopped) by the SU control processing unit 14. As a result of this determination, the sensor device SU ends this process when the operation is terminated (stopped) (Yes), while the sensor device SU ends the operation (No) when the operation is not terminated (stopped). The SU returns the process to the process S21.

The sensor device SU operates as described above for each of the detection of a predetermined action and the reception of a nurse call by the monitored person Ob.

Next, the operation of the management server device SV will be described. FIG. 10 is a flowchart showing the operation of the management server device.

In FIG. 10, the management server device SV determines whether or not a communication signal has been received by the SV communication IF unit 21 by the SV control unit 221 of the SV control processing unit 22 (S31). As a result of this determination, when the communication signal is not received (No), the management server device SV returns the process to S31, and when the result of the determination is that the communication signal is received (Yes), the management server device SV returns the process to S31. The management server device SV executes the next process S32. That is, the management server device SV is waiting for the reception of the communication signal.

In the process S32, the management server device SV determines the type of the received communication signal by the SV control unit 221. As a result of this determination, the management server device SV determines that the received communication signal is either a first event notification communication signal or a second event notification communication signal (first event notification, second event notification). When the processing S36 is executed after the processing S33 is executed and the received communication signal is the event video notification communication signal (event video notification), the processing S36 is executed after the processing S34 is executed, and the reception When the generated communication signal is not the first event notification communication signal, the second event notification communication signal, or the event video notification communication signal (other), the process S36 is executed after the process S35 is executed.

In the processing S33, the management server device SV processes the monitoring information for processing the first event notification communication signal and the second event notification communication signal received from the sensor device SU in the processing S31 by the SV monitoring processing unit 222 of the SV control processing unit 22. Executes the processing of. More specifically, first, the SV monitoring processing unit 222 SV monitors the monitoring information regarding the monitoring of the monitored person Ob, which is accommodated in the first or second event notification communication signal received from the sensor device SU in the processing S31. It is stored (recorded) in the information storage unit 231. Then, the SV monitoring processing unit 222 stores the notification destination corresponding to the sensor device SU that transmitted the first or second event notification communication signal received in the processing S31 in the inter-device information storage unit 232. Select (search) from. Next, the SV monitoring processing unit 222 transmits the third event notification communication signal to the terminal devices SP and TA of the selected notification destination. As described above, when the event information contained in the first or second event notification communication signal received in the process S31 is the predetermined action, the third event notification communication signal includes the process S31. Has a sensor ID accommodated in the first or second event notification communication signal received in, event information and a target image, and a sensor ID accommodated in the first or second event notification communication signal as a video download destination. The communication address corresponding to the sensor device SU is accommodated. On the other hand, when the event information contained in the first event notification communication signal received in the process S31 is a nurse call, the sensor ID and event information accommodated in the first event notification communication signal received in the process S31. Is housed.

In the processing S34, the management server device SV executes the processing of the event video accommodated in the event video notification communication signal received from the sensor device SU in the processing S31 by the SV monitoring processing unit 222 of the SV control processing unit 22. More specifically, the SV monitoring processing unit 222 retrieves the sensor ID, event information, and event video accommodated in the event video notification communication signal received from the sensor device SU in the processing S31, and the extracted event video has a file name. The event video (event video file) is stored in the SV video storage unit 234 of the SV storage unit 23, and the extracted sensor ID and event information are associated with this file name and stored in the SV video storage unit 234. .. The file name of the event video may be set as appropriate, but for example, "the reception time of the event video notification communication signal represented by the sensor ID_year, month, day, and day. "Etc.). With such a file name, the moving image can be associated with the generated sensor device SU and each reception time by the file name, and the file names may be duplicated in one monitored person monitoring support system MS. not.

In the process S35, the management server device SV executes an appropriate process according to the communication signal received in the process S31 by the SV control process unit 22.

Then, in the process S36 executed after each of the processes S33 to S35, the management server device SV determines whether or not its operation is terminated (stopped) by the SV control processing unit 22. As a result of this determination, the management server device SV ends this process when the operation is terminated (stopped) (Yes), while the management is managed when the operation is not terminated (stopped) (No). The server device SV returns the process to the process S31.

The management server device SV operates as described above with respect to the communication signals received from each device SU, SP, and TA.

On the other hand, when the fixed terminal device SP and the mobile terminal device TA receive the second event notification communication signal from the management server device SV via the network NW, the sensor ID and event information and the like accommodated in the second event notification communication signal are received. Each piece of information is stored (recorded) as monitoring information of the monitored person Ob monitored by the sensor device SU having this sensor ID, and the monitoring information is displayed. As a result, the event detected by the sensor device SU is displayed on the fixed terminal device SP and the mobile terminal device TA, and is notified (notified). Users (monitorers) of the fixed terminal device SP and the mobile terminal device TA can download and refer to the event video from the management server device SV as needed, call out using the mobile terminal device TA, or make a nurse call. Depending on the situation, a voice call may be made using the mobile terminal device TA, a moving image may be delivered by streaming from the sensor device SU, and the moving image may be referred to live.

As described above, each device operates, monitors the monitored person Ob, and supports the monitoring of the monitor. However, the operation of the entire monitored person monitoring support system is combined with the effects of the live video and the event video. I will explain. FIG. 11 is a sequence diagram showing the operation of the monitored person monitoring support system in the first case. FIG. 12 is a sequence diagram showing the operation of the monitored person monitoring support system in the second case. FIG. 13 is a diagram showing an example of a authenticity determination screen displayed on the authenticity determination terminal device in the first case. FIG. 14 is a diagram showing a authenticity determination screen in which only a live moving image is displayed in the second case. FIG. 15 is a diagram showing a authenticity determination screen on which an event moving image and a live moving image are displayed in the second case.

In FIG. 11, in the first case, when the sensor device SU detects a fall under the first detection condition by each of the above-mentioned processes S10 to S13 shown in FIG. 7, the sensor device SU executes the process S15, and the process S16 first executes the process. The event notification communication signal is transmitted to the management server device SV (C11), and the processes S19 and S20 are sequentially executed to end this process. When the management server device SV receives the first event notification communication signal by each of the above-mentioned processes S31 to S33 shown in FIG. 9, the management server device SV stores (records) the monitoring information stored in the first event notification communication signal, and notifies the third event. A communication signal is transmitted to predetermined terminal devices SP and TA (C12), processing S36 is executed, and in this example, processing is returned to processing S31. Further, the sensor device SU generates an event video by each process of the processes S151 to S154 shown in FIG. 8 and transmits the event video notification communication signal to the management server device SV (C13). When the management server device SV receives the event video notification communication signal by each of the above-mentioned processes S31, process S32, and process S34 shown in FIG. 9, the management server device SV stores (records) the event video accommodated in the event video notification communication signal, and processes S36. Is executed, and in this example, the process is returned to the process S31.

On the other hand, when the sensor device SU detects a fall under the second detection condition by each of the above-mentioned processes S10 to S13 shown in FIG. 7, the sensor device SU executes the process S17, and the process S18 makes the authenticity determination request notification communication signal true. It is transmitted to the false determination terminal device JT (C21), and the processes S19 and S20 are sequentially executed to end the present process.

Upon receiving the authenticity determination request notification communication signal, the authenticity determination terminal device JT transmits the live video request communication signal to the sensor device SU (C22), and receives the video distribution from the sensor device SU by streaming (C23). , Display the video live on the authenticity judgment screen. This authenticity determination screen is a screen for displaying an image referred to for determining the authenticity of the detection of the predetermined action and receiving the determination result, and an example thereof is shown in FIG. ..

The authenticity determination screen 61 shown in FIG. 13 includes a detection moving image display area 611, a live moving image display area 612, a “notification required” button 613, and a “notification not required” button 614. The detected moving image display area 611 is an area for displaying an event moving image. The live moving image display area 612 is an area for displaying a moving image live. The "notification required" button 613 is a button for inputting an instruction to notify the sensor device SU of the detection of the predetermined action. The authenticity determination person inputs and operates the "notification required" button 613 when it is determined that the predetermined action has occurred in the monitored person Ob as a result of the authenticity determination and the detection of the predetermined action is correct. .. The “notification unnecessary” button 614 is a button for inputting an instruction not to notify the sensor device SU of the detection of the predetermined action. As a result of the authenticity determination, the authenticity determination person inputs the "notification unnecessary" button 614 when it is determined that the predetermined action has not occurred in the monitored person Ob and the detection of the predetermined action is incorrect. Manipulate.

In the example shown in FIG. 13, since the event video has not been received at this point, the video is not displayed in the video display area 611 at the time of detection, but the live video display area 612 is in a fallen state. A video of the monitored person Ob is displayed. Therefore, the authenticity judge determines that the monitored person Ob has fallen as the predetermined action by referring to the live video without referring to the event video, and the detection of the fall is correct. can. Therefore, the authenticity determination person inputs and operates the "notification required" button 613.

When the "notification required" button 613 is input and operated, the authenticity determination terminal device JT sends a notification required notification communication signal for notifying the sensor device SU of an instruction requiring notification, and a authenticity determination request notification signal. Reply to the sensor device SU of the transmission source (C24).

The sensor device SU generates a second event notification communication signal by each of the processes S21 to S23 shown in FIG. 9, and transmits the generated second event notification communication signal to the management server device SV (C25) for processing. S26 is executed, and in this example, the process is returned to the process S21. When the management server device SV receives the second event notification communication signal by each of the above-mentioned processes S31 to S33 shown in FIG. 9, the management server device SV stores (records) the monitoring information stored in the second event notification communication signal, and notifies the third event. A communication signal is transmitted to predetermined terminal devices SP and TA (C26), processing S36 is executed, and in this example, processing is returned to processing S31.

Then, the sensor device SU generates an event video by each of the processes S171 to S174 shown in FIG. 8 and transmits the event video notification communication signal to each of the authenticity determination terminal device JT and the management server device SV (C27). -1, 27-2). When the management server device SV receives the event video notification communication signal by each of the above-mentioned processes S31, process S32, and process S34 shown in FIG. 9, the management server device SV stores (records) the event video accommodated in the event video notification communication signal, and processes S36. Is executed, and in this example, the process is returned to the process S31.

When the authenticity can be determined by referring only to the live video in this way, the third event notification communication signal can be transmitted to the predetermined terminal device SP and TA earlier, and the event detection can be performed earlier to the predetermined terminal device SP. , TA can be notified.

In the second case, in FIG. 12, when the sensor device SU detects a fall under the first detection condition by each process of the above-mentioned processes S10 to S13 shown in FIG. 7, the first event notification communication is performed as in FIG. The signal is transmitted to the management server device SV (C11), and when the management server device SV receives the first event notification communication signal, it stores (records) the monitoring information accommodated in the first event notification communication signal, and stores (records) the third event notification communication signal. Transmission to predetermined terminal devices SP and TA (C12). Further, the sensor device SU generates an event video, transmits the event video notification communication signal to the management server device SV (C13), and when the management server device SV receives the event video notification communication signal, it is accommodated in the event video notification communication signal. Memorize (record) event videos.

On the other hand, when the sensor device SU detects a fall under the second detection condition by each of the above-mentioned processes S10 to S13 shown in FIG. 7, the sensor device SU executes the process S17 and determines the authenticity by the process S18 in the same manner as the process C21. The request notification communication signal is transmitted to the authenticity determination terminal device JT (C31), and the processes S19 and S20 are sequentially executed to end this process.

Upon receiving the authenticity determination request notification communication signal, the authenticity determination terminal device JT transmits the live video request communication signal to the sensor device SU (C32) and streams it from the sensor device SU, as in the processing C22 and the processing C23, respectively. When the video is delivered at (C33), the video is displayed live on the authenticity determination screen 61. An example is shown in FIG. Even in the authenticity determination screen 61 of the example shown in FIG. 14, since the event moving image is not received at this point, the detection moving image display area 611 is similar to the authenticity determination screen 61 of the example shown in FIG. , The event video is not displayed. On the other hand, in the live moving image display area 612, in the example shown in FIG. 14, a moving image of the monitored person Ob in a state of kneeling and crouching is displayed. For this reason, it is difficult for the authenticity judge to determine whether the live video is merely crouching or crouching as a result of a fall.

While the authenticity determination person is worried about the determination, the sensor device SU generates an event video by each of the processes S171 to S174 shown in FIG. 8, and the event video notification communication signal is transmitted to the authenticity determination terminal device JT. And transmission to each of the management server device SV (C34-1, 34-2). When the management server device SV receives the event video notification communication signal by each of the above-mentioned processes S31, process S32, and process S34 shown in FIG. 9, the management server device SV stores (records) the event video accommodated in the event video notification communication signal, and processes S36. Is executed, and in this example, the process is returned to the process S31. When the authenticity determination terminal device JT receives the event video notification communication signal, the event video accommodated in the event video notification communication signal is displayed in the detection video display area 611 of the authenticity determination screen 61. An example is shown in FIG.

On the authenticity determination screen 61 of the example shown in FIG. 15, the event moving image is reproduced, and the moving image at the time of falling is displayed in the moving image display area 611 at the time of detection. Therefore, the authenticity determination person can determine that the monitored person Ob has fallen as the predetermined action by referring to the event video, and that the detection of the fall is correct. Therefore, the authenticity determination person inputs and operates the "notification required" button 613.

When the "notification required" button 613 is input and operated, the authenticity determination terminal device JT sends a notification required notification communication signal for notifying the sensor device SU of an instruction requiring notification, and a authenticity determination request notification signal. Reply to the sensor device SU of the transmission source (C35-1).

Similar to the process C25, the sensor device SU generates a second event notification communication signal by each process of the processes S21 to S23 shown in FIG. 9, and transmits the generated second event notification communication signal to the management server device SV. (C36), the process S26 is executed, and in this example, the process is returned to the process S21. When the management server device SV receives the second event notification communication signal by each of the above-mentioned processes S31 to S33 shown in FIG. 9, similarly to the process C26, the management server device SV stores (records) the monitoring information contained therein. Then, the third event notification communication signal is transmitted to the predetermined terminal devices SP and TA (C37), the process S36 is executed, and in this example, the process is returned to the process S31.

In this way, even if it is difficult to determine the truth by referring only to the live video, the truth can be determined by referring to the event video, false alarms can be further reduced, and false alarms can be further reduced.

In the above example, as shown by the broken line in FIG. 12, when the "notification unnecessary" button 614 is input and operated on the authenticity determination screen 61, the authenticity determination terminal device detects an instruction that notification is unnecessary. The notification-free notification communication signal for notifying the device SU is returned to the sensor device SU that is the transmission source of the authenticity determination request notification signal. When the sensor device SU receives a notification-free communication signal from the authenticity determination terminal device JT by each of the processes S21, S22, and S24 shown in FIG. 9, the event information temporarily stored in the SU storage unit 16 And the target image is erased, the process S26 is executed, and in this example, the process is returned to the process S21. Therefore, in this case, the second event notification communication signal is not transmitted from the sensor device SU to the management server device SV. This can reduce false alarms.

As described above, the monitored person monitoring support system MS, the sensor device SU as an example of the monitored person monitoring device, and the monitored person monitoring method implemented therein perform a plurality of actions of the same type in the present embodiment. Since the detection is performed under the detection conditions, it is possible to detect the same type of behavior under relatively strict detection conditions and relatively loose detection conditions, so that it is possible to reduce false alarms. Detection of the behavior under the relatively loose detection conditions may result in a false alarm. In the monitored person monitoring support system MS, the sensor device SU and its method, such a relatively loose detection condition can be set as the second detection condition, and the monitored person monitoring support system MS, the sensor device SU can be set. And the method thereof notify the authenticity determination terminal device JT (an example of the second device of the second notification destination) of the detection of the action under the second detection condition, and the authenticity determination terminal device JT notifies the authenticity determination terminal device JT of the action. When an instruction to notify the detection to the management server device SV (an example of the first device of the first notification destination) is received, the detection of the action is further notified to the management server device SV, so that erroneous reporting can be reduced. In particular, since the user (determiner) who handles the authenticity determination terminal device JT can refer to the moving image notified from the sensor device SU, the action can be visually determined, so that the action occurs more accurately. It can be judged. Therefore, the monitored person monitoring support system MS, the sensor device SU, and the method thereof can more appropriately notify the behavior, and can reduce false alarms and false alarms.

The monitored person monitoring support system MS, the sensor device SU, and the method thereof are relatively low cost because the management server device SV and the authenticity determination terminal device JT are handled by the first and second operators, which are different from each other. It is possible to have the second business operator handle the authenticity determination terminal device JT, and the cost can be reduced.

The monitored person monitoring support system MS, the sensor device SU, and the method thereof transmit the behavior detection video (event video) and the live video to the authenticity determination terminal device JT. Therefore, since the user (determiner) who handles the authenticity determination terminal device JT can refer to these, the occurrence of the above action can be determined more accurately.

In the above-described embodiment, the sensor device SU transmits the event video to the management server device SV and the authenticity determination terminal device JT, respectively, in the case of the second detection condition, but the sensor device SU manages the event video. It is transmitted only to the server device SV, and information (event video download information) for downloading the event video transmitted to the management server device SV from the management server device SV is transmitted to the authenticity determination terminal device JT. , May be configured. The event video download information is, for example, a communication address of the management server device SV and information for specifying the event video (event video file name).

Further, in the above-described embodiment, the number of authenticity determination terminal devices JT is one, but may be multiple. According to this, since there are a plurality of authenticity determination terminal devices JT of the second notification destination, the visual determination can be shared. Further, in such a case, the plurality of authenticity determination terminal devices JT may be configured to operate in different time zones by dividing the day into a plurality of times. According to this, since the plurality of authenticity determination terminal devices JT operate in different time zones in which the day is divided into a plurality of times, the visual determination can be shared by time division. In particular, as shown in FIG. 16, the three first to third authenticity determination terminal devices JT-1, JT-2, and JT-3 are separated from each other by about 120 degrees at the first to third positions of longitude. By arranging the terminals in the first to third positions, the three first to third authenticity determination terminal devices JT-1, JT-2, and JT-3 can be operated in the daytime zone of each of the first to third positions. FIG. 16 is a diagram for explaining a modified form of the monitored person monitoring support system. For example, the first authenticity determination terminal device JT-1 is arranged in the Central American region, the second authenticity determination terminal device JT-2 is arranged in the Middle East region, and the third authenticity determination terminal device JT-3 is located. , For example, it is located in the Southeast Asian region of the islands such as the Indonesian Islands. In such a case, each of the plurality of time zones includes a time zone before and after the time zone and an overlap portion, and the authenticity determination terminal device JT operating in the later time zone operates in the time zone. The operation of the own machine may be notified by transmitting a communication signal (operation start notification communication signal) accommodating the operation information indicating the operation of the own machine to the authenticity determination terminal device JT. For example, as shown by a broken line in FIGS. 13 to 15, a "business start" button 616 for instructing the transmission of the operation start notification communication signal is further provided on the authenticity determination screen 61, and is provided by the authenticity determination person JM. Upon receiving the input operation of the "business start" button 616, the authenticity determination terminal device JT is configured to transmit an operation start notification communication signal to the authenticity determination terminal device JT operating in the previous time zone. According to this, when the visual determination is shared by time division, the visual determination can be continuously performed for 24 hours.
