As shown in FIG. 3C, the watching device 2 executes a state monitoring process described in detail later (step SC1).
In the state monitoring process of step SC1, the monitoring device 2 monitors whether or not the cared person is in a predetermined state based on the input from the sensor unit 23T, and the cared person is in the predetermined state. If this happens, it will be detected. When the watching device 2 detects that the state of the cared person has reached a predetermined state, the watching device 2 watches and notifies the system management device 4 of that.
When the state of the care recipient becomes predetermined by this state monitoring process, this is automatically detected by the watching device 2, and this is automatically notified to the watching system management device 4 by the watching device 2. For this reason, the care worker goes around the group home GH and can reduce the burden on the work of visually confirming the state of the care recipient.

In the present embodiment, it is assumed that there are a “bed sitting state”, a “bed leaving state”, and an “abnormal operation state” as predetermined states.
In the sitting position on the bed, the posture of the cared person is lying on the bed BH (hereinafter referred to as “the lying position”), and the sitting position on the bed BH with the upper body raised (hereinafter referred to as “the sitting position on the bed”). It means the state changed to “posture”.)
The bed leaving state is a posture in which the care recipient is sitting on the end of the bed BH with his / her feet out of the bed BH from the supine position or the sitting position (hereinafter referred to as “bed end sitting position”). ) Means the state changed to. When the cared person's posture becomes the bed end sitting position, the cared person is assumed to leave the bed.
The abnormal operation state is a state where the care recipient is performing an abnormal operation. The abnormal operation is, for example, an operation of jumping on the bed BH or an operation of falling around the bed BH.

  As shown in FIG. 3B, when receiving a notification from the monitoring device 2, the monitoring system management device 4 notifies the information processing terminal 5 of this (step SB1).

As shown in FIG. 3A, upon receiving a notification from the monitoring system management device 4, the information processing terminal 5 executes an information update process described in detail later (step SA1).
In the information update process in step SA1, the information processing terminal 5 is in a predetermined state with information indicating the date and time when the monitoring device 2 notifies the monitoring system management device 4 (hereinafter referred to as “notification date and time information”). Information indicating the room number of the occupancy room GH1 in which the cared person enters (hereinafter referred to as “room number information”) and information indicating the state (predetermined state) of the cared person (hereinafter referred to as “cared person state”). Information ”) is displayed on the information processing terminal display panel 521 in a list together with past information.

Further, in the information update process in step SA1, the information processing terminal 5 records information including the notification date / time information, the room number information, and the care receiver status information in the log file 541.
By this information update processing, the care worker can later obtain useful information related to care such as the change in the status of the care recipient by referring to the information recorded in the log file 541.

  As shown in FIG. 3B, when the notification is received from the monitoring device 2, the monitoring system management device 4 executes a state analysis process described in detail later (step SB2).

  In the state analysis process of step SB2, the monitoring system management device 4 reflects the date and time when the notification is received from the monitoring device 2 and the level of care required of the care recipient of the care recipient (described later), so that the notification terminal 6 It is determined whether or not a notification needs to be made. When it is determined that it is necessary to notify the notification terminal 6, the watching system management apparatus 4 notifies the notification terminal 6.

As shown in FIG. 3D, when receiving a notification from the monitoring system management device 4, the notification terminal 6 executes a state notification process described in detail later (step SD1).
In the state notification process of step SD1, the notification terminal 6 displays the room number information and the care receiver state information on the notification terminal display 621 in a predetermined manner to be described later.
Through this state notification process, the caregiver assigned with the notification terminal 6 can recognize that the care receiver has entered a predetermined state and can perform corresponding care. As will be described later, when a caregiver of a plurality of caregivers performs care corresponding to a care recipient, other caregivers can recognize that, It is prevented that the care worker in charge of giving care corresponding to the same cared person occurs.

Here, when the cared person is in a predetermined state, considering the time when the cared person is in the predetermined state, the transition to the predetermined state may be caused by the normal operation of the cared person . For example, even if the cared person's state becomes the sitting position on the bed at the time when the cared person's wake-up is assumed, this is because the transition to the state is normal for the cared person who is woken up. Due to movement.
As will be described later, care recipients do not necessarily need the same care, and the level of care required varies depending on the degree of progression of dementia and the physical condition of each person.
Based on the above, by performing the state analysis process of step SB2, notification to the notification terminal 6 is performed unnecessarily, and an increase in the burden on the caregiver is suppressed.

  In the state analysis process in step SB2, the monitoring system management device 4 reflects the date and time when the notification is received from the monitoring device 2 and the level of care required of the care recipient of the care recipient (described later). It is determined whether or not notification to the device 2 is necessary. When it is determined that it is necessary to notify the watching device 2, the watching system management device 4 notifies the watching device 2.

As shown in FIG. 3C, when receiving a notification from the monitoring system management device 4, the monitoring device 2 executes a care receiver guidance process that will be described in detail later (step SC2).
In the care receiver guidance process in step SC2, the watching device 2 guides the care receiver in a predetermined state by voice so that the care receiver takes an appropriate action in a manner described later. .
By this care receiver guidance process, an appropriate operation of the care receiver is promoted, and the safety of the care receiver is improved.

  Next, the information processing terminal 5, the monitoring system management device 4, and the notification terminal 6 cooperate to execute a corresponding process (step SA2, step SB3, and step SD2). The handling process will be described later.

  The basic operation of each device of the watching system 1 has been described above. As described above, the watching system 1 notifies the caregiver when the care receiver is in a predetermined state. For this reason, the care worker can perform the corresponding care to the care recipient promptly after the care receiver is in a predetermined state. Thereby, the burden accompanying the caregiver of the caregiver is reduced, and the caregiver can live a safer and more secure life.

  Next, processing executed by each device of the watching system 1 will be described in detail.

  In the generation of long-time image data in step SE2, the watching device control unit 20 executes the following processing. Here, the sensor unit 23T is provided in the occupancy room GH1, and the detection range of the infrared sensor 23 includes a high temperature region such as a floor warmed by sunlight. Based on this, in step SE2, the monitoring device control unit 20 generates long-time image data D3 obtained by superimposing the short-time image data D2 for a predetermined time in order to store the area.

  In the generation of the analysis image data in step SE3, the monitoring device control unit 20 performs three types of analysis based on the short-time image data D2 generated in step SE1 and the long-time image data D3 generated in step SE3. Image data D4 is generated.

  In the selection of the analysis image data in step SE4, the monitoring device control unit 20 selects data used for detection of the care receiver posture among the three types of analysis image data D4 generated in step SE3.

  In the posture analysis in step SE5, the watching device control unit 20 detects the care receiver posture based on the analysis image data selected in step SE4.

  Hereinafter, each process of step SE1-step SE5 is explained in full detail.

<Generation of Short-Time Image Data D2 (Step SE1)>
As described above, the watching device control unit 20 generates the temperature image data D1 at a predetermined cycle (for example, every 100 ms). However, each pixel of the temperature image data D1 includes a noise component. Based on this, in step SE1, the monitoring device control unit 20 removes the noise component by superimposing the short-time image data D2 of the previous frame (generated immediately before).

Specifically, the monitoring device control unit 20 obtains the pixel temperature value F _X of each pixel of the short-time image data D2 by the following equation S1.
Formula S1: F _X = (P _X + (C-1) * F _X-1 ) / C
(Where F _X-1 is the pixel temperature value of the corresponding pixel in the short-time image data D2 one frame before. P _X is the pixel temperature value of the corresponding pixel in the newly generated temperature image data D1. C is Note that if there are many noise components, the noise removal function can be enhanced by increasing the period and increasing the value of C.)

<Generation of long-time image data D3 (step SE2)>
In step SE2, the watching device control unit 20 superimposes the short-time image data D2 to generate long-time image data D3. The long-time image data D3 is stored as background information. If there is a movement of the cared person within the detection range of the infrared sensor 23, the movement of the cared person can be clearly captured by comparison with the image data D3 for a long time.
The watching device controller 20 updates the long-time image data D3 every time the short-time image data is generated.

The watching device control unit 20 obtains the pixel temperature value S _X of each pixel of the long-time image data D3 by the following equation S2.
Formula S2: S _X = (F _X + (L-1) * S _X-1 ) / L
(However, S _X-1 is the pixel temperature value of the corresponding pixel in the long-time image data D3 one frame before. L is a constant and L> C. Note that the value of L is relative to the value of C. (In this example, C = 5 and L = 3000.)

<Generation of Analysis Image Data D4 (Step SE3)>
In step SE3, the watching device control unit 20 generates the following three types of analysis image data D4 based on the short-time image data D2 and the long-time image data D3. That is, the watching device control unit 20 generates three types of analysis image data D4, that is, motion analysis image data D41, maximum temperature point image data D42, and temperature difference amount image data D43.
Hereinafter, the operation analysis image data D41, the maximum temperature point image data D42, and the temperature difference amount image data D43 and a method for generating these data will be described.

<Operation analysis image data D41>
FIG. 7 is a diagram used for explaining the motion analysis image data D41.
When generating the motion analysis image data D41, the monitoring device control unit 20 compares the short-time image data D2 and the long-time image data D3, and extracts pixels whose temperature of the short-time image data D2 is higher than a certain level. Here, the watching device control unit 20 recognizes adjacent pixels as one block. This makes it possible to grasp the size of the image and its position.
FIG. 7A shows motion analysis image data when a cared person enters the detection range of the infrared sensor 23. In FIG. 7A, a region W1 indicates a pixel whose temperature is higher than a certain level, and a pixel GG1 indicates the temperature centroid of the region W1.

FIG. 7B1 shows the short-time image data D2, and FIG. 7B shows motion analysis image data D41 based on the short-time image data D2 of (B1).
Further, as shown in FIGS. 7B1 and 7B2, when there are a plurality of moving objects and noise information based on the motion analysis image data D41, these can be individually recognized as different data. .

  Note that the detection target of the motion analysis image data D41 is a moving object, but the motion analysis image data D41 is used as long as it is a stationary object whose period is such that there is a difference between the short time image data D2 and the long time image data D3. Detection is possible.

<Maximum temperature point image data D42>
The watching device control unit 20 searches (extracts) a pixel having the highest temperature in the short-time image data D2, and uses a region having a relatively high temperature near the searched (extracted) pixel as an image, so that the highest temperature point image is obtained. Data D42 is generated.
According to the maximum temperature point image data D42, it is possible to detect a stationary detection object. However, according to the maximum temperature point image data D42, a high-temperature object that is not detected, such as a stationary stove, is also detected.
FIG. 8A1 shows an example of the short-time image data D2, and FIG. 8A2 shows the maximum temperature point image data D42 based on the short-time image data D2 of (A1).
FIG. 8B1 shows another example of the short-time image data D2, and FIG. 8B2 shows the maximum temperature point image data D42 based on the short-time image data D2 of (B1).

<Temperature difference amount image data D43>
The watching device control unit 20 calculates the temperature difference of each pixel between the short-time image data D2 and the long-time image data D3, and generates temperature difference amount image data D43 indicating the temperature difference of each pixel.
The motion analysis image data D41 and the maximum temperature point image data D42 display the position to be detected (the coordinates in the data) and the area, whereas the temperature difference amount image data D43 shows the temperature difference. There is a feature.
FIG. 9A1 shows an example of the short-time image data D2, and FIG. 9A shows temperature difference amount image data D43 based on the short-time image data D2 of (A1).
FIG. 9B1 shows another example of the short-time image data D2, and FIG. 9B2 shows temperature difference amount image data D43 based on the short-time image data D2 of (B1).

<Selection of analysis image data D4 to be used (step SE4)>
Here, in detecting the care receiver posture, the monitoring device control unit 20 does not use all of the motion analysis image data D41, the maximum temperature point image data D42, and the temperature difference amount image data D43, but performs motion analysis. Based on the image data D41, the operation status of the detection target is determined, the data to be used is selected according to the operation status, and the selected data is used.

FIG. 10 is a flowchart showing the operation of the watching device 2 when the analysis image data D4 is selected.
In selecting the analysis image data D4, the watching device control unit 20 executes the following processing (step SF1).
That is, the watching device control unit 20 analyzes the motion analysis image data D41 and obtains the coordinates of the pixel of the temperature centroid (hereinafter referred to as “temperature centroid coordinates”) in the data (see FIG. 7A).

Next, the watching device control unit 20 acquires a difference between the temperature centroid coordinates and the coordinates indicated by the position information (hereinafter referred to as “centroid movement amount”).
The position information is information having the coordinates of the motion analysis image data D41 as values. Although details will be described later, the value of the position information is updated as needed in the posture analysis in step SE5.

  After obtaining the difference between the temperature center-of-gravity coordinates and the coordinates indicated by the position information, the watching device control unit 20 obtains the stationary time. The stationary time is a time during which the state in which the movement amount of the temperature centroid coordinates is within a predetermined range continues. The predetermined range is a range in which it can be estimated that the detection target is not moving or slightly moving.

After acquiring the center-of-gravity movement amount and the stationary time as described above, the watching device control unit 20 executes the following processing (step SF2).
That is, the watching device control unit 20 classifies the movement amount of the center of gravity as one of no movement amount, small movement amount, medium movement amount, and large movement amount.
The center-of-gravity movement amount is classified as no movement amount when the center-of-gravity movement amount is “0” dots or the temperature center-of-gravity coordinates cannot be detected.
The center-of-gravity movement amount is classified as small movement amount when both the movement amount in the vertical axis direction and the movement amount in the horizontal axis direction are “3” dots or less.
The center-of-gravity movement amount is the movement amount when either the movement amount in the vertical axis direction or the movement amount in the horizontal axis direction is “4” dots or more and the total movement amount is “10” dots or less. Classified in.
The center-of-gravity movement amount is classified as a large movement amount when none of the above applies, that is, when the total movement amount is “11” dots or more.

  Next, the watching device control unit 20 classifies the stationary time as one of short time, during time, and long time. The stationary time is classified as a short time when it is shorter than the first threshold, with the first threshold value and the second threshold value (first threshold value <second threshold value) as a boundary. If it is longer than the threshold, it is separated into time lengths, otherwise it is classified into time.

Next, the watching device control unit 20 selects analysis image data D4 used for detection of the care receiver posture based on the combination of the classification of the center of gravity movement and the classification of the stationary time.
In the present embodiment, the type of analysis image data D4 to be used is determined for each combination of the classification of the center-of-gravity movement amount and the classification of the stationary time, and the watching device control unit 20 analyzes the analysis image data D4 corresponding to the combination. Select.

FIG. 11 is a matrix diagram showing the analysis image data D4 selected for each combination of the centroid movement amount classification and the stationary time classification.
As shown in FIG. 11, when the rest time is short, the center of gravity movement amount is small and the movement amount is small / no movement amount, the watching device controller 20 selects the motion analysis image data D41 and the temperature difference amount image data D43. To do.
In addition, when the rest time is short and the center-of-gravity movement amount is in the movement amount, the watching device control unit 20 selects the motion analysis image data D41 and the temperature difference amount image data D43.
When the rest time is short and the movement amount of the center of gravity is large, the watching device control unit 20 selects the motion analysis image data D41 and the temperature difference amount image data D43.
In addition, when the rest time: during the time, the center-of-gravity movement amount: small movement amount / no movement amount, the watching device control unit 20 selects the motion analysis image data D41 and the maximum temperature point image data D42.
In addition, when the rest time is “time” and the center-of-gravity movement amount is “movement amount”, the watching device control unit 20 selects the motion analysis image data D41 and the temperature difference amount image data D43.
In addition, when the rest time: during the time, the center of gravity movement amount: the movement amount is large, the watching device control unit 20 selects the motion analysis image data D41 and the temperature difference amount image data D43.
In addition, when the stationary time is the time length and the center-of-gravity movement amount is the movement amount small / no movement amount, the watching device control unit 20 selects the maximum temperature point image data D42.
In addition, when the stationary time is the time length and the center-of-gravity movement amount is the movement amount, the watching device control unit 20 selects the motion analysis image data D41 and the maximum temperature point image data D42.
In addition, when the stationary time is the time length and the center of gravity moving amount is large, the watching device control unit 20 selects the motion analysis image data D41 and the maximum temperature point image data D42.

<Attitude analysis (step SE5)>
In the posture analysis of step SE5, the watching device control unit 20 first executes the following processing based on the selected analysis image data D4 for each combination of the centroid movement amount classification and the stationary time classification.
Hereinafter, the process performed by the monitoring device control unit 20 for each combination of the classification of the center-of-gravity movement amount and the classification of the stationary time will be described.

<Still time: short time, center of gravity moving amount: small moving amount / no moving amount (in this case, selected analysis image data D4 is motion analysis image data D41 and temperature difference amount image data D43)>
When the stationary time is short and the center-of-gravity movement amount is small / no movement amount, the detection target is operating or there is almost no time elapsed after the stationary state. Therefore, it is possible to analyze data based on the motion analysis image data D41 and the temperature difference amount image data D43 which are not easily affected by noise.

FIG. 12A shows an example of the motion analysis image data D41, and FIG. 12B shows temperature difference amount image data D43 corresponding to the motion analysis image data D41 of FIG.
In FIGS. 12A and 12B (also (C) to be described later), the data based on the infrared sensor 23L and the data based on the infrared sensor 23R are detected within the detection range for convenience of description. Are connected to form a continuous area.

First, based on the motion analysis image data D41, the watching device control unit 20 estimates the care receiver's posture from the shape of the image in the data.
Note that the form of the cared person estimated by the shape of the image based on the motion analysis image data D41 is expressed as “posture” and is distinguished from “posture”.
In the example of FIG. 12A, since the image in the motion analysis image data D41 has an elongated shape, it is estimated that the position of the care receiver is a posture corresponding to the supine posture. On the other hand, from the analysis of the motion analysis image data D41, it is difficult to estimate a region corresponding to a body part (head, trunk, leg, etc.) of the cared person.
Based on this, the monitoring device control unit 20 detects a region (hereinafter referred to as “feature region”) having a certain characteristic in the temperature distribution based on the temperature difference amount image data D43. In the example of FIG. 12 (B), a state in which three characteristic regions AR1, AR2, and AR3 are detected is shown.
Next, the monitoring device control unit 20 uses the correlation between the detected feature region and the temperature distribution feature of the body part, or image processing such as pattern matching, to which part of the body the region corresponds to. Is estimated. In the example of FIG. 12B, the monitoring device control unit 20 estimates the area AR1 as an area corresponding to the head, estimates the area AR2 as an area corresponding to the trunk, and sets the area AR3 as an area corresponding to the leg. Estimated.

  As described above, the watching device control unit 20 estimates the position of the cared person based on the motion analysis image data D41 and corresponds to the body part of the cared person based on the temperature difference amount image data D43. The feature area to be estimated is estimated.

FIG. 12C is a diagram showing motion analysis image data D41 for explaining another process of the watching device control unit 20 in the case where the stationary time: short time, and the center of gravity movement amount: small movement amount / no movement amount. It is.
The watching device control unit 20 also checks whether there is anything that enters the detection range of the sensor unit 23T in conjunction with the above-described processing. As in the case of transition from the motion analysis image data D41 shown in FIG. 12 (A) to the motion analysis image data D41 shown in FIG. 12 (C), a new image having a certain area or more (image in FIG. 12 (C)). When Z1) appears, the watching device control unit 20 determines that there is an entry into the detection range.

<Still time: short time, center of gravity moving amount: moving amount (in this case, selected analysis image data D4 is motion analysis image data D41 and temperature difference amount image data D43)>
When the stationary time: short time and the center of gravity moving amount: during the moving amount, the watching device control unit 20 executes the same processing as in the case of the above stationary time: short time, center of gravity moving amount: small moving amount / no moving amount. To do.

<Still time: short time, center of gravity movement amount: large movement amount (in this case, selected analysis image data D4 is motion analysis image data D41 and temperature difference amount image data D43)>
When the stationary time is short and the movement amount of the center of gravity is large, the watching device control unit 20 performs the same processing as in the case where the stationary time is short and the movement amount of the center of gravity is small: the movement amount is small / no movement amount. At the same time, a noise determination process is performed in addition to the process.

In the noise determination process, the watching device control unit 20 determines whether or not the image in the motion analysis image data D41 is noise information.
Here, in the motion analysis image data D41, the cared person corresponding to the detected image moves so that the image moves to the left side in the data, but relatively large noise information exists in the data. In such a case, only the analysis based on the motion analysis image data D41 may erroneously detect that the care recipient corresponding to the image has moved so that the image moves to the right side in the data.
Based on this, the monitoring device control unit 20 removes noise information using the temperature difference amount image data D43.

FIG. 13A shows an example of the motion analysis image data D41, and FIG. 13B shows temperature difference amount image data D43 corresponding to the motion analysis image data D41 of FIG.
In the motion analysis image data D41 shown in FIG. 13A, the noise information may cause the image Z2 to be erroneously detected. The monitoring device control unit 20 detects that the temperature difference in the region corresponding to the image Z2 is very small based on the temperature difference amount image data D43 shown in FIG. 13B, and the image Z2 is noise information. Determine. By this determination, it is possible to suppress the occurrence of erroneous detection due to the presence of noise information.

It should be noted that noise determination may also be performed when the stationary time is short and the center of gravity movement amount is small / no movement amount and when the stationary time is short time and the center of gravity movement amount is during the movement amount. However, in these cases, since the effect of suppressing erroneous detection by noise determination is small, noise determination is not performed in consideration of processing efficiency. On the other hand, when the rest time is short and the movement amount of the center of gravity is large, it is necessary to accurately determine where the heat source is located, so it is necessary to perform noise determination.
Note that the robustness of the infrared sensor 23 is taken into consideration when the stationary time is short, the center of gravity movement is small / no movement, and the stationary time is short and the center of gravity is moving. Then, noise information may be removed.

<Still time: during time, center of gravity movement amount: small movement amount / no movement amount (in this case, selected analysis image data D4 is motion analysis image data D41 and maximum temperature point image data D42)>
Resting time: When it is during the time, a certain time has passed since the detection target is stationary.
The still time classified as “during time” is a time (number of frames) longer than “C” in the above-described equation S1, and is shorter than “L” in equation S2.

  When the stationary time: during the time, the center of gravity movement amount: small movement amount / no movement amount, there is a certain temperature difference. Therefore, the motion analysis based on the motion analysis image data D41 that searches for a region with a temperature difference greater than a certain value is normal Function. However, since the temperature difference is small, the highest temperature point image data D42 is used instead of the temperature difference amount image data D43, and the analysis based on the highest temperature point image data D42 is performed. That is, as the stationary time becomes longer, the temperature difference does not change and the image in the temperature difference amount image data D43 disappears. Therefore, the analysis based on the temperature difference amount image data D43 (identification of the region corresponding to the image) Etc.) becomes less reliable. Based on this, in the analysis, the highest temperature point image data D42 is used instead of the temperature difference amount image data D43.

14A shows an example of the short-time image data D2, FIG. 14B shows motion analysis image data D41 corresponding to the short-time image data D2 in FIG. 14A, and FIG. 14C shows the short-time image data D2 in FIG. The temperature difference amount image data D43 corresponding to the image data D2 is shown, and (D) shows the maximum temperature point image data D42 corresponding to the short-time image data D2 of (A).
The watching device control unit 20 detects an image in the data based on the motion analysis image data D41. At that time, if the area of the image is small, the watching device control unit 20 lowers the threshold value of the pixel temperature value when the pixel is regarded as a pixel constituting the image, and on the other hand, if the area of the image is large, it is regarded as a pixel constituting the image. The threshold value of the pixel temperature value is raised. In this embodiment, the threshold is lowered by “0.25” ° C. when the area of the image is 50 dots or less, while the threshold is raised by “0.25” ° C. when the area is 200 dots or more. Thereby, the area of an image can be made into an appropriate range.

Here, it is not appropriate to use the temperature difference amount image data D43 when detecting an image in the motion analysis image data D41. This is because, as shown in FIG. 14C, the image should be detected as a large temperature difference region in the temperature difference amount image data D43, but the stationary time is long and the temperature changes with time. This is because it is detected that the temperature difference is small.
Based on this, the watching device control unit 20 uses the maximum temperature point image data D42 to assist in detection of an image based on the motion analysis image data D41. This is because, as shown in FIG. 14D, the maximum temperature point image data D42 is hardly affected by the length of the stationary time.

  The watching device control unit 20 detects an image based on the motion analysis image data D41 and the maximum temperature point image data D42, and based on the detected image, the posture of the cared person and the cared person Estimate the acquisition area corresponding to the body part.

<Still Time: During Time, Center of Gravity Movement Amount: Movement Amount (In this case, selected analysis image data D4 is motion analysis image data D41 and temperature difference amount image data D43)>
When the movement amount of the center of gravity is within the movement amount, the movement amount of the target (heat source) is large. Therefore, in the temperature difference amount image data D43, the image area before the movement and the image area after the movement are separated from each other. Can be distinguished. Based on the above, the monitoring device control unit 20 performs an analysis using the temperature difference amount image data D43.

FIG. 15A1 shows the case where the cared person moves in a predetermined direction from the position corresponding to the region X1 in the figure with the movement amount corresponding to the center of gravity movement amount: the movement amount small in the case of the stationary time: the time. (A2) shows the temperature difference amount image data D43 corresponding to the short-time image data D2 of (A1).
FIG. 15B1 shows a case where the cared person moves in a predetermined direction from the position corresponding to the region X1 in the figure with the movement amount corresponding to the center of gravity movement amount: the movement amount in the stationary time: time. (B2) shows the temperature difference amount image data D43 corresponding to the short time image data D2 of (B1).
As shown in FIGS. 15A1 and 15A2, when the stationary time: during the time and the center of gravity movement amount: the movement amount is small, the image exists in the region X1 for a certain period of time or longer. Even when the image is used, the movement of the image to the region X1 is difficult to detect.
On the other hand, as shown in FIGS. 15B1 and 15B2, when the stationary time is during time and the center-of-gravity moving amount is during moving amount, the detection target is in a region that is determined to be low temperature in the long-time image data D3. Since the heat source moves, the movement of the image to the region X1 can also be accurately detected using the temperature difference amount image data D43.

  Based on the above, the monitoring device control unit 20 estimates the position of the cared person based on the motion analysis image data D41 and the temperature difference amount image data D43, and features corresponding to the body part of the cared person Estimate the region.

<Still time: When the center-of-gravity movement amount is large during the time (in this case, the selected analysis image data D4 is the motion analysis image data D41 and the temperature difference amount image data D43)>
When the stationary time: during the time, the center of gravity movement amount: the amount of movement is large, the watching device control unit 20 executes the same processing as in the case where the stationary time: during time, the center of gravity movement amount: during the amount of movement.

<Still time: time length, center of gravity movement amount: small movement amount / no movement amount (in this case, selected analysis image data D4 is maximum temperature point image data D42)>
As described above, the stationary time classified as “time length” is longer than “L” in the above-described equation S2.
When the stationary time is larger than “L”, there is almost no difference between the short-time image data D2 and the long-time image data D3, and only the highest temperature point image data D42 can be used. However, this does not apply if there is a target action.

When the resting time is the time length and the center-of-gravity movement amount: the movement amount is small / no movement amount, the watching device control unit 20 estimates the position of the cared person based on the maximum temperature point image data D42 and the cared person The feature region corresponding to the body part is estimated.
The monitoring device control unit 20 basically does not detect the entry of the sensor unit 23T into the detection range, but if there is a large reaction in the motion analysis image data D41, it has newly entered the reaction position. judge.

<Still time: time length, center of gravity movement amount: during movement amount (in this case, selected analysis image data D4 is motion analysis image data D41 and maximum temperature point image data D42>
When the stationary time: time length and the center of gravity moving amount: during the moving amount, the watching device control unit 20 executes the same processing as in the case of the above-described stationary time: during time, the center of gravity moving amount: during the moving amount.
In this case, since the cared person is not expected to move at a stroke from a state where he / she is not moving at all, the removal of noise information based on the noise determination process is also executed.

<Still time: time length, center of gravity movement amount: large movement amount (in this case, selected analysis image data D4 is motion analysis image data D41 and maximum temperature point image data D42>
When the stationary time is the time length and the center of gravity moving amount is the large moving amount, the watching device control unit 20 executes the same processing as when the stationary time is the time length and the center of gravity moving amount is the moving amount.

In the above, the process performed by the watching device control unit 20 for each combination of the classification of the center of gravity movement amount and the classification of the stationary time has been described.
As described above, the monitoring device control unit 20 generates appropriate analysis image data D4 corresponding to the state of the detection target (care recipient) according to the combination of the classification of the center of gravity movement and the classification of the stationary time. Based on the selected analysis image data D4, the characteristics of the cared person and the feature region corresponding to the body part of the cared person are estimated based on the characteristics of the image data.

  After executing the analysis based on the selected analysis image data D4, the watching device control unit 20 executes a position information update process.

FIG. 16 is a flowchart showing the operation of the watching device 2 when the position information update process is executed.
As shown in FIG. 16, the watching device control unit 20 determines whether or not the classification of the center-of-gravity movement amount is medium or large (step SG1). When the classification of the center-of-gravity movement amount is neither the movement amount nor the movement amount large (step SG1: NO), the watching device control unit 20 does not update the position information and ends the process.

When the classification of the center-of-gravity movement amount is medium movement amount or large movement amount (step SG1: YES), the watching device control unit 20 determines whether or not the temperature center-of-gravity coordinates are acquired based on the noise information. Is determined (step SG2).
When the temperature center-of-gravity coordinates are based on the noise information (step SG2: NO), the watching device control unit 20 does not update the position information and ends the process.

When the temperature center-of-gravity coordinates are not based on the noise information (step SG2: YES), the watching device control unit 20 updates the position information value with the value of the temperature center-of-gravity coordinates (step SG3).
Next, the watching device control unit 20 resets the value of the stationary time (step SG4).

As described above, when the classification of the center-of-gravity movement amount is the movement amount or the movement amount is large, and the acquired temperature center-of-gravity coordinates are not derived from the noise information, the watching device control unit 20 displays the movement information. Update. As a result, it is detected that the detection target (caregiver) has moved by a certain amount or more, and the position information value is updated when the detection is reliable.
Regarding the update of the position information, the monitoring device control unit 20 may cause a slight difference in the temperature center-of-gravity coordinates in the motion analysis image data D41 due to noise even when the detection target is not moving. Therefore, even when the difference between the acquired temperature center-of-gravity coordinates and the position information value is small, the position information is not updated.

After performing the position information update process, the watching device control unit 20 detects the position of the care recipient.
As described above, the sensor unit 23T includes the two infrared sensors 23L and the infrared sensor 23R that are spaced apart from each other on the left and right. Using this, the monitoring device control unit 20 detects the short-term image data D2 generated based on the input from each sensor and the difference in the coordinates of the temperature gravity center of the long-time image data D3 party, The distance to the sensor unit 23T is detected, and the position of the care recipient is detected based on the detected distance.
In addition, by setting in advance the correspondence between the area of the short-time image data D2 and the long-time image data D3 party and the area of the bed BH, it is possible to accurately detect whether the care recipient is in the bed BH. it can.

After performing the position information update process, the watching device control unit 20 detects the care receiver posture.
The watching device control unit 20 detects the care receiver posture based on the posture of the care receiver estimated by the above-described method and the characteristic region corresponding to the body part of the care receiver.
Here, there is a correspondence relationship between the positional relationship of the characteristic regions corresponding to the body part of the care recipient and the posture of the care recipient. Using this, the watching device control unit 20 specifies the positional relationship of the feature region, specifies the care receiver posture corresponding to the specified positional relationship, reflects the position of the care receiver, and receives the care receiver. Detect posture.

With the method described above, the watching device control unit 20 detects the care receiver posture at a predetermined cycle.
In the state monitoring process of step SC1, the monitoring device control unit 20 monitors whether or not the care receiver posture has changed based on the care receiver posture detected at a predetermined cycle, and the care receiver posture has changed. By detecting that there was a situation, it is detected that the state of the cared person has reached a predetermined state.
For example, the monitoring device control unit 20 detects that the care recipient's posture has changed from the lying posture to the sitting posture on the bed, so that the care recipient's state has become the sitting posture on the bed. Is detected.
Further, for example, the watching device control unit 20 detects that the posture of the care recipient has changed from the lying posture or the sitting posture to the bed end sitting posture, so that the state of the care recipient is the bed leaving state. It detects that it became.
Further, for example, when the posture of the care receiver changes in a pattern that is determined to be abnormal behavior, the watching device control unit 20 detects that the care receiver is in an abnormal operation state.

  In the state monitoring process of step SC1, when it is detected that the state of the cared person becomes a predetermined state, the watching device control unit 20 includes the cared person state information (information indicating the state of the cared person), The state notification data including the room number information (information indicating the room number of the occupancy room GH1 provided with the watching device 2) is transmitted to the watching system management device 4.

<Information Update Processing of Information Processing Terminal 5 (Step SA1)>
Hereinafter, the information update process executed by the information processing terminal 5 in step SA1 in the flowchart of FIG.
In the information update process, the information processing terminal control unit 50 of the information processing terminal 5 receives the above-described notification date and time information, room number information, and care receiver status information from the monitoring system management device 4.
Based on the received information, the information processing terminal control unit 50 lists information including the notification date / time information, the room number information, and the care receiver state information on the information processing terminal display panel 521 together with past information.

<State analysis process of the monitoring system management device 4 (step SB2)>
Next, the state analysis process executed by the watching system management apparatus 4 in step SB2 in the flowchart of FIG.

Here, the care recipient does not necessarily need the same care, and the level of care required varies depending on the state of dementia and the physical condition.
In the present embodiment, the level of the body state is divided into seven levels of care-requiring body levels L1 to L7 in accordance with the degree of necessary care. It should be noted that the higher the body level requiring care, the more necessary care is required.
Moreover, in this embodiment, the level of the dementia state is divided into seven levels of dementia requiring dementia levels L1 to L7 according to the degree of necessary care. The higher the level of dementia requiring care, the more necessary care is required.

In this embodiment, the level of care required is set for each combination of the level of care required body level and the level of dementia requiring care.
FIG. 18 is a matrix diagram showing the relationship between the combination of the body level requiring care and the level of dementia requiring nursing care and the level requiring nursing care. As shown in FIG. 18, there are three levels of care required, that is, the level of care required L1 to the level of care required L3, and the higher the level, the thicker the care is required.

The management device storage unit 43 of the monitoring system management device 4 associates, for each cared person, information indicating the room number of the occupancy room GH1 in which the cared person occupies and information indicating the level of care required of the cared person. The nursing care level table 441 to be stored is stored.
FIG. 19A is a diagram showing a level of care required table 441.
As shown in FIG. 19A, the care-requiring level table 441 has a plurality of records, and each record associates information indicating a room number with information indicating a need-for-care level.
The caregiver can generate a new record in the care-required level table 441 by using a predetermined means, delete the record, and change the content of the record.

The management device storage unit 43 of the watching system management device 4 stores a determination table 442.
FIG. 19B shows the determination table 442.
As shown in FIG. 19B, the determination table 442 includes a combination of the level of care required and the state of the person being cared for (in this embodiment, the sitting position on the bed, the bed leaving state, or the abnormal operation state). In addition, information indicating whether notification to the notification terminal 6 is necessary and information indicating whether notification to the monitoring device 2 is necessary are stored in association with each other.
As described above, when the cared person is in a predetermined state, depending on the relationship between the state of the cared person and the level of care required of the cared person, whether or not corresponding care is required for the cared person, and The need for guidance from the care recipient is different. Based on this, in the determination table 442, information indicating whether or not notification to the notification terminal 6 is necessary and notification to the monitoring device 2 are required for each combination of the level of care required and the status of the care recipient. Information indicating whether or not.

As described above, when the cared person is in a predetermined state, the transition to the predetermined state is caused by the normal operation of the cared person in consideration of the time when the predetermined state is reached There is.
Based on this, the management device storage unit 43 has a determination table 442 that is different for each time zone.
In each determination table 442, in the determination table 442, for each combination of the level of care required and the status of the cared person, appropriate information reflecting the time zone when the status of the cared person becomes a predetermined state is reflected. (Information indicating whether notification to the notification terminal 6 is necessary and information indicating whether notification to the monitoring device 2 is necessary) are associated with each other.

In the state analysis process in step SB2, the management device control unit 40 of the monitoring system management device 4 executes the following processing based on the room number information included in the state notification data received from the monitoring device 2. In other words, the management device control unit 40 refers to the long-term care level table 441 and acquires the long-term care level associated with the room number in the table. The care-requiring level acquired here is the care-requiring level of the care recipient who is in a predetermined state.
Next, the management device control unit 40 identifies a time zone to which the time when the monitoring device 2 is notified belongs, and refers to the determination table 442 corresponding to the identified time zone. Therefore, the management device control unit 40, in the determination table 442, the combination of the level of care recipient and the status of the cared person indicated by the status information of the cared person included in the status notification data received from the monitoring device 2 Get information associated with. The information acquired here is information indicating whether notification to the notification terminal 6 is necessary and information indicating whether notification to the monitoring device 2 is necessary.
Next, the management device control unit 40 determines whether or not notification to the notification terminal 6 is necessary based on the information acquired from the determination table 442. When it is determined that notification to the notification terminal 6 is necessary, the management device control unit 40 transmits display information data including room number information and care receiver status information to the notification terminal 6.
Further, the management device control unit 40 determines whether or not notification to the watching device 2 is necessary based on the information acquired from the determination table 442. When it is determined that notification to the monitoring device 2 is necessary, the management device control unit 40 and the care receiver status information and information indicating the care level of the care recipient (hereinafter referred to as “care level information”). Is transmitted to the watching device 2.

<Care guidance process of the watching device 2>
Next, the care receiver guidance process executed by the watching device 2 at step SC2 in the flowchart of FIG.

In the care receiver guidance process, the watching device control unit 20 of the watching device 2 receives the guidance information data from the watching device 2. As described above, the guidance information data is data including care recipient status information and care level information.
Here, the watching device storage unit 24 of the watching device 2 stores a combination of the care receiver status information and the level of care required level information, and voice data of voice to be output in voice corresponding to the combination. Remember. In the table, each piece of voice data is voice data of voice that guides the cared person appropriately corresponding to the corresponding combination.
The watching device control unit 20 refers to the table and acquires voice data associated with the combination of the care receiver status information and the care level information included in the guidance information data. Next, the watching device control unit 20 controls the audio output unit 22 based on the acquired audio data, and outputs audio based on the audio data.
FIG. 20 is a diagram illustrating an example of audio content that is output as audio for each combination of the state of the care recipient and the level of care required of the care recipient.

In this way, when the cared person is in a predetermined state by executing the care receiver guidance process, the cared person depends on the cared person's state and the level of care required of the cared person. Appropriate guidance is output as a voice so that the person being cared for can take an appropriate action.
Thereby, the safety of the care recipient is further improved.

<Status notification process of notification terminal 6 (step SD2)>
Next, the state notification process executed by the notification terminal 6 at step SD1 in the flowchart of FIG.

First, the structure of the notification terminal 6 will be described.
FIG. 21A is a side view of the notification terminal 6, and FIG. 21B is a front view of the notification terminal 6.
The casing of the notification terminal 6 is of a size that can fit in the palm of a human hand, and the caregiver can hold the notification terminal 6 with one hand.
As shown in FIG. 21B, the notification terminal 6 is provided with a notification terminal display 621 in a wide front area.

  The notification terminal display 621 has a room number display area Q1. In the room number display area Q1, the room number is segmentally displayed by a three-digit numerical value.

Further, the notification terminal display 621 has a state display area Q2. The state display area Q2 displays an image showing the care receiver state (bed sitting state, bed leaving state, and abnormal operation state) in the following manner.
FIG. 21C is a diagram showing an upper sitting position image G1 that is an image in the sitting position on the bed displayed in the state display area Q2. FIG. 21D is a diagram showing a bed leaving image G2 that is an image of the bed bed leaving state displayed in the state display area Q2. FIG. 21E is a diagram showing an abnormal operation image G3 that is an image of an abnormal operation state displayed in the state display area Q2.
As shown in FIGS. 21C to 21E, since an image imitating the cared person state is displayed in the state display area Q2, the care worker displays the image displayed in the state display area Q2. By visually recognizing, the state of the cared person can be immediately grasped sensuously.

Further, the notification terminal display 621 has a progress status display area Q3.
Although details will be described later, information on the progress status of the corresponding nursing care (hereinafter referred to as “corresponding nursing care progress status”) is displayed in the progress status display area Q3. Specifically, in the progress status display area Q3, when the corresponding care is being performed for the care recipient, a corresponding image P that is an image indicating that is displayed, and the corresponding care corresponding to the care recipient is displayed. When the image is not being executed, the corresponding image P is not displayed.

As shown in FIGS. 21A and 21B, a slide-type notification selection switch 631 is provided on one side surface of the notification terminal 6.
The notification selection switch 631 is a switch for selecting a method for notifying a caregiver that a notification has been made when a notification is given to the notification terminal 6. There are three methods of notification to a caregiver (hereinafter referred to as “notification method”): notification by vibration, notification by beep sound, and notification by vibration and beep sound. The caregiver can select one of the three notification methods using the notification selection switch 631.
In the group home GH, for example, notification by a beep sound may not be appropriate, for example, at a time when a cared person is sleeping at night. Based on this, the caregiver can easily select a notification method suitable for the environment.

As shown in FIG. 21B, a push-down main switch 632 is provided on the other side of the notification terminal 6.
The main switch 632 can perform two types of operations: an operation of pressing the switch for a short period of time not longer than a predetermined period (for example, 1 second) and an operation of pressing the switch for a period longer than the predetermined period. Hereinafter, an operation of pressing the main switch 632 in a short period is expressed as a “short press operation”, and an operation of pressing the main switch 632 in a long period is expressed as a “long press operation”.
The situation in which the main switch 632 is operated and the operation of the notification terminal 6 when the main switch 632 is operated will be described later.
Thus, in the notification terminal 6 according to the present embodiment, the switch operated by the caregiver is configured by the hard key. Thereby, the person in charge of care can operate the switch with a finger feeling without looking at the notification terminal 6. Note that the switch provided in the notification terminal 6 is not limited to a hard key. For example, the terminal display 621 may be configured with a touch panel, and the switch of the notification terminal 6 may be configured with soft keys displayed on the touch panel.

FIG. 22 is a flowchart showing the operation of the notification terminal 6 when display information data including room number information and care receiver status information is received from the monitoring system management device 4 in the status notification process.
As shown in FIG. 22, the notification terminal control unit 60 of the notification terminal 6 receives the display information data from the watching system management device 4 (step SH1).

Next, the notification terminal control unit 60 generates one record in the notification table 641 based on the received display information data (step SH2).
FIG. 23 is a diagram showing the notification table 641.
As shown in FIG. 23, one record in the notification table 641 stores state notification date / time information, room number information, cared person state information, and progress status information in association with each other.
The status notification date / time information is information indicating the date / time when the monitoring system management device 4 is notified to the notification terminal 6.
The progress status information is information indicating the progress of the corresponding nursing care, specifically, information indicating that the corresponding nursing care has not been started (hereinafter referred to as “unsupported information”), and the corresponding nursing care is being executed. Information indicating that there is information (hereinafter referred to as “in-process information”).
In step SH <b> 2, the notification terminal control unit 60 acquires the date and time when there is a notification from the watching system management device 4. Next, one record is generated in the notification table 641. In the generated new record, status notification date / time information indicating the acquired date / time, room number information included in the display information data, and subject information included in the display information data. Caregiver status information and progress status information indicating that corresponding care has not been started are stored in association with each other.

Next, the notification terminal control unit 60 displays information corresponding to the notification terminal display 621 based on the received display information data (step SH3). Specifically, the room number indicated by the room number information is segment-displayed by a three-digit numerical value in the room number display area Q1 of the notification terminal display 621. In addition, the notification terminal control unit 60 displays an image corresponding to the cared person state indicated by the cared person state information in the state display area Q2. Specifically, when the cared person's state is the sitting position on the bed, the sitting position image G1 is displayed, and when the cared person's state is the bed leaving state, the bed leaving image G2 is displayed. When is in the above-described operation state, the abnormal operation image G3 is displayed. Further, the notification terminal control unit 60 does not display the corresponding image P in the progress status display area Q3. This is because at the time when the notification to the notification terminal 6 is made, none of the caregivers is providing corresponding care for the care recipient.
FIG. 24 shows an example of information displayed on the notification terminal display 621 by the notification terminal control unit 60 in step SH3.

  Next, the notification terminal control unit 60 notifies the caregiver that there is a notification from the watching system management device 4 by the notification method selected by the notification selection switch 631 (step SH4). For example, when notification by vibration is selected, the notification terminal control unit 60 controls the vibration unit 65 to vibrate the housing of the notification terminal 6. For example, when the notification by the beep sound is selected, the notification terminal control unit 60 controls the beep sound output unit 66 to output the beep sound. For example, when notification by vibration and beep sound is selected, the notification terminal control unit 60 controls the vibration unit 65 to vibrate the housing of the notification terminal 6 and also controls the beep sound output unit 662. Outputs a beep sound.

  The care worker recognizes that the notification system management device 4 has notified the notification terminal 6 by the notification performed by the notification terminal control unit 60 in step SH4. After the recognition, the care worker visually confirms and confirms the notification terminal display 621 of the notification terminal 6. The caregiver can recognize the room number of the occupancy room GH1 in which the care receiver who has entered a predetermined state moves by referring to the room number display area Q1. The caregiver can recognize the status of the care recipient by referring to the status display area Q2. Moreover, the care worker can recognize that the corresponding care is not performed for the care recipient by recognizing that the corresponding image P is not displayed in the progress display area Q3.

Next, the notification terminal control unit 60 monitors whether or not the main switch 632 has been pressed for a short time (step SH5).
When the short press operation is performed (step SH5: YES), the notification terminal control unit 60 stops the notification that the notification has been given (step SH6).

Next, the display content displayed on the notification terminal display 621 by the notification terminal 6 during the state notification process and the operation of the notification terminal 6 when the care worker performs an operation on the main switch 632 will be described in detail.
There are a plurality of phases in which the main switch 632 is operated during the execution of the state notification process. In the following, the display content on the notification terminal 6 and the operation of the notification terminal 6 will be described for each phase.
In the following description, one screen of the notification terminal display 621 in which the room number of the occupancy room GH1 for a certain cared person, the state of the cared person, and the corresponding care progress status is displayed. It is called “page screen”. As will be described later, the caregiver can switch the page screen displayed on the notification terminal display 621 by a predetermined method.

<Phase in which the caregiver who provides caregiving for the care recipient is determined>
First, a phase in which a care worker who performs care for the care recipient is determined will be described.
As described above, the corresponding image P is not displayed in the progress display area Q3 on the page screen (hereinafter, referred to as “unsupported page screen”) related to the care recipient who has not started corresponding care. FIG. 25A1 shows an example of an unsupported page screen.
Based on the content of the unsupported page screen, the caregiver determines whether he / she is in charge of the caregiving of the care recipient. In the example of FIG. 25 (A1), the caregiver refers to the unsupported page screen shown in FIG. 25 (A1), and enters the occupancy room GH1 of “Room 301” based on the content of the unsupported page screen. For the care recipients who move in, it is determined whether or not they are in charge of corresponding care. For example, the caregiver determines whether or not he / she is in charge of corresponding care of the care recipient based on the positional relationship between his / her position and the occupancy room GH1 of the room number indicated by the unsupported page screen. .
When it is determined that the caregiver is responsible for the caregiver of the care recipient related to the unsupported page screen, the caregiver operates the main switch 632 for a long time while the unsupported page screen is displayed.

When the notification terminal control unit 60 detects that the main switch 632 has been pressed for a long time when an unsupported page screen is displayed, the notification terminal control unit 60 has a corresponding record in the notification table 641. Change the progress information from unsupported information to in-service information. Furthermore, the notification terminal control unit 60 displays the corresponding image P in the progress status display area Q3 of the unsupported page screen based on the corresponding record in the notification table 641.
In the present embodiment, the fact that the caregiver of the cared person is determined is the start of the caregiver of the cared person.

FIG. 25A2 shows a screen that the notification terminal control unit 60 displays on the notification terminal display 621 when the main switch 632 is pressed for a long time while the unsupported page screen of (A1) is displayed. Show.
As shown in FIG. 25 (A2), when a care worker in charge who performs care for the care recipient is determined, a corresponding image P is displayed in the progress display area Q3. For this reason, the caregiver determines whether or not the corresponding image P is present on the page screen, so that the caregiver of the care recipient of the caregiver related to the page screen has started (the corresponding caregiving person in charge of the corresponding caregiving). Can be recognized.
In the following description, a page screen (a page screen on which a corresponding image P is displayed) related to a care receiver who has started corresponding care is expressed as a “corresponding page screen”.

Here, one caregiver operates the main switch 632 for a long time while the unsupported page screen related to the one caregiver is displayed, and the caregiver's corresponding care starts by the one caregiver. When it is done, the non-corresponding page screen relating to the one care receiver in the notification terminal 6 of the other caregiver is changed to a corresponding page screen in which the corresponding image P is displayed in the progress display area Q3. The processing performed at that time will be described in detail later.
The other caregiver recognizes that the unsupported page screen related to the one care receiver has changed to the corresponding page screen in his / her notification terminal 6, so that the caregiver other than himself / herself can It can be recognized that the corresponding caregiver of the first care recipient has started. And based on the said recognition, the said other care worker can recognize that he does not need to take charge of the corresponding care of the said 1 care receiver.

<Phase in which caregiving of care recipients has been completed>
Next, the phase in which the care recipient's corresponding care has been completed will be described.
The caregiver in charge of the caregiver of the care recipient performs the caregiving of the caregiver. For example, the caregiver goes to the occupancy room GH1 in which the cared person resides and performs care corresponding to the condition of the cared person.
When the caregiver's corresponding care is completed, the caregiver operates the notification terminal 6 by a method described later, and causes the notification terminal display 621 to display the corresponding page screen for the care recipient who has completed the corresponding care. . FIG. 25 (B1) is a diagram showing an example of the corresponding page screen.
The care receiver performs a long press operation on the main switch 632 in a state where the corresponding page screen for the care receiver who has completed the corresponding care is displayed.

FIG. 25B2 is a diagram illustrating an example of a screen displayed on the notification terminal display 621 when the main switch 632 is operated in a state where the corresponding page screen of (B1) is displayed.
When the notification terminal control unit 60 detects that the main switch 632 has been pressed for a long time while the corresponding page screen is displayed, the notification terminal control unit 60 stores the corresponding record from the notification table 641. delete. Furthermore, as shown in FIG. 25 (B2), the notification terminal control unit 60 displays information indicating “-” in the room number display area Q1 and erases the image displayed in the status display area Q2. In addition, the corresponding image P displayed in the progress display area Q3 is deleted. After displaying the screen shown in FIG. 25 (B2) for a certain period, the notification terminal control unit 60 stops displaying the screen and displays another screen according to the rules.
In response to the long press operation of the main switch 632 in a state where the corresponding page screen relating to the care recipient who has completed the corresponding care is displayed, the corresponding page screen is erased and is not displayed. Thereafter, even if the page screen is switched by a method described later, the corresponding page screen is not displayed. In addition, since it becomes unnecessary to perform corresponding care about a care receiver when the corresponding care of the care receiver is completed, it is not necessary to display a corresponding page screen for the care receiver on the notification terminal 6 thereafter.

Here, when one care worker performs a long press operation on the main switch 632 while the corresponding page screen for the one care recipient is displayed, and the corresponding page screen is not displayed, another care worker Also on the notification terminal 6, the corresponding page screen corresponding to the one care recipient is not displayed. The processing performed at that time will be described in detail later.
The caregiver in charge of the corresponding care and the other caregivers recognize that the corresponding page screen for one care receiver is no longer displayed on their notification terminal 6, so that 1 It can be recognized that the corresponding caregiver is not in a situation where the corresponding care is not started, and that the corresponding care is not being executed.

<Phase in which the caregiver confirms the care recipient before the start of the corresponding care and the care recipient who is performing the corresponding care>
Next, a phase in which the caregiver confirms the care recipient before the corresponding care is started and the care recipient who is performing the corresponding care will be described.

The notification terminal control unit 60 displays the page screen to be displayed when the main switch 632 is pressed for a short time by the caregiver while one page screen is displayed on the notification terminal display 621. Change to
At that time, the notification terminal control unit 60 changes the page screen in the order in which the corresponding notifications are received, and the oldest notification is displayed when the main switch 632 is operated for a short time while the page screen related to the latest notification is displayed. The page screen concerning is displayed.
Hereinafter, the transition of the page screen executed by the notification terminal control unit 60 will be specifically described with an example.

FIG. 26 is a diagram used for explaining the transition of the page screen performed by the notification terminal control unit 60.
In the description using FIG. 26 below, the notification terminal 6 sends notifications from the monitoring system management device 4 in the order of notification related to “Room 301”, notification related to “Room 303”, and notification related to “Room 307”. It is assumed that it has been accepted, and notifications relating to other occupancy rooms GH1 have not been accepted.
In the following description using FIG. 26, the notification terminal 6 executes display of a page screen and transition of the page screen based on the notification table 641 illustrated in FIG.

  As shown in FIG. 26A, it is assumed that the page screen related to “Room 301” is displayed on the notification terminal display 621. In this state, it is assumed that the care worker performs a short press operation on the main switch 632. When the notification terminal control unit 60 detects that a short press operation has been performed, the notification terminal control unit 60 displays a page screen related to the notification received next to the notification related to “Room 301” based on the notification table 641. In this example, as illustrated in FIG. 26B, the notification terminal control unit 60 displays a page screen relating to “Room 303”.

  Assume that the caregiver performs a short press operation on the main switch 632 when the page screen (FIG. 26B) relating to “Room 303” is displayed. When the notification terminal control unit 60 detects that a short press operation has been performed, the notification terminal control unit 60 displays a page screen related to the notification received next to the notification related to “Room 303” based on the notification table 641. In this example, as shown in FIG. 26C, the notification terminal control unit 60 displays a page screen related to “Room 307”.

  It is assumed that the care worker performs a short press operation on the main switch 632 when the page screen (FIG. 26C) relating to “Room 307” is displayed. When the notification terminal control unit 60 detects that a short press operation has been performed, the notification terminal control unit 60 recognizes that there is no notification newly received in time from the notification related to “Room 303” based on the notification table 641, and most recently The page screen related to the notification received in the past is displayed. In this example, the notification terminal control unit 60 displays a page screen related to “Room 301” as shown in FIG.

Further, the notification terminal control unit 60 controls the vibration unit 65 to vibrate the casing of the notification terminal 6 for a predetermined period when the screen is changed to the page screen related to the notification received the oldest in time. Let In this example, when the screen is changed from the page screen of FIG. 26C to the page screen of FIG. 26A, the notification terminal control unit 60 holds the housing of the notification terminal 6 for a predetermined period. Vibrate.
The caregiver recognizes that the housing of the notification terminal 6 vibrates in accordance with the transition of the page screen, so that the page screen newly displayed after the transition is the notification that the notification terminal 6 has received the oldest. It can be recognized that this is the page screen.
Here, if the status of the cared person is the same, the cared person related to the notification with the old time received by the notification terminal 6, in other words, the cared person with the old time in the predetermined state is earlier. It can be said that it is necessary to provide nursing care at the stage. And according to this embodiment, the caregiver can recognize the order when the caregiver for whom the corresponding care has not started is in a predetermined state, and determines the priority for performing the corresponding care can do.

  As described above, the caregiver performs a short press operation on the main switch 632 to change the page screen, so that the care recipient before the corresponding care is started and the care recipient who is performing the corresponding care. Can be confirmed.
