Description

  The present invention relates to a life support notification system.

  In recent years, with the increase in the elderly population, the number of elderly living alone has been increasing. When elderly people live alone, so-called dementia tends to progress, and forgetfulness may increase as an initial symptom of dementia. When many people forget things, they forget even basic daily activities that are indispensable for living, for example, forgetting excretion such as urination and defecation and incontinence. If you leave such a situation, forgetfulness may worsen and dementia may progress, and if you forget to excrete and incontinence, the self-esteem of the person will be damaged, and the work of cleaning up will increase. There is also a problem that the burden on the person increases. If there is a living person, it is difficult to forget to excrete by speaking to the living person, but since there is no living person who sees the daily life of the elderly in the elderly alone, the timing of excretion Could not be noticed.

  By the way, as a method of detecting whether or not the resident has excreted, it is possible to measure the weight before and after excretion, and to detect that the excretion act was performed from the weight difference, but forgetfulness In the case of a terrible resident, there is a possibility that the act of measuring the weight on a scale is forgotten, so there is a possibility that a forgetful meal cannot be detected reliably even though the burden on the resident is large.

  Therefore, as a toilet sensor device that detects excretion behavior without imposing a burden on the measurement of the resident, a sensor that detects that the user is sitting on the toilet seat from the pressure applied to the toilet seat, and the sensor detects the seating A timer that counts the time from the time point until it rises from the toilet seat, and the signal processing unit that compares the usage time measured by the timer with the reference time, and determines that the user has excreted if the usage time is longer than the reference time Has been proposed in the past to automatically detect the usage time and the number of times of use when the user uses the toilet (see, for example, Patent Document 1).

JP 2000-237098 A

  However, the toilet sensor device disclosed in Patent Document 1 cannot detect that a resident has forgotten the excretion behavior only by detecting the usage time and the number of times the user has used the toilet. It was not possible to remind residents of forgetting to excrete and encourage them to excrete.

  The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to easily detect forgetting to excrete without taking the trouble of detecting the resident and to forget to forget to excrete. The object is to provide a life support notification system capable of notifying residents.

In order to achieve the above object, the invention of claim 1 includes an entry detection means for detecting entry into a toilet, an excretion detection means for detecting the excretion behavior of a resident based on the detection result of the entry detection means, A first time measuring means for measuring the current time; an action schedule information storing means for storing action schedule information including at least one of time information for excretion action and frequency information for excretion action in a predetermined time zone; If the excretion action scheduled in the action schedule information is not detected based on the detection result of the excretion detection means and the time measured by the first time measuring means, the forgetting excretion action means for determining that the excretion action is forgotten; When the means to determine the excretion behavior forget and a informing means for informing the excretion behavior forget for the dwelling people, the action schedule information is information of the time interval of excretion behavior, excretion behavior forget determination means, before Excretion detecting means during a period from the time of detection until the elapse of the time interval is equal to or determines that the excretion behavior forget to be detected excretion behavior.

The invention according to claim 2 is an entrance detection means for detecting entry into the toilet, an excretion detection means for detecting the excretion behavior of a resident based on the detection result of the entrance detection means, and a first timekeeping that measures the current time. Means, action schedule information storage means for storing action schedule information including at least one of time information on which excretion action is performed and number of times information on which excretion action is performed in a predetermined time zone, a detection result of the excretion detection means, and If the excretion action forgetting determination means for determining that the excretion action is forgotten and the excretion action forgetting determination means determine that the excretion action forgetting is forgotten, if the excretion action scheduled in the action schedule information based on the time measured by the first timing means cannot be detected and an informing means for informing the excretion behavior forget for the dwelling people, the action schedule information is information of the scheduled number of times that the excretion behavior at a given time band is expected to be carried out, excretion behavior forget decision hand It is characterized in that the excretion detection means to determine the excretion behavior forgotten If you do not detect the excretion behavior more than expected number of times in the time period.

A third aspect of the present invention, in any one invention of claim 1 or 2, Bei give a second counting means for counting the time that the entrance detecting means is detecting continuously the entry state, action schedule information storage The means stores action schedule information for each of urine and stool, and the excretion detection means compares the time measurement result of the second timing means with a predetermined threshold time to determine whether the excretion action is urine or stool. The urinary excretion behavior determination means determines whether the urination excretion behavior and the stool excretion behavior are scheduled in the action schedule information based on the detection result of the excretion detection means and the time measured by the first timing means. If both cannot be detected, it is determined that the excretion behavior is forgotten.

  According to the first aspect of the present invention, if the entry detecting means detects entry into the toilet and detects the excretion action, and the excretion action scheduled in the action schedule information cannot be detected, the excretion action forgetting determination means is excreted. Since it is determined that the person has forgotten the action and the resident himself does not need to make any measurement to detect the forgetting the excretion action, the resident is surely detected to forget the excretion action without making the measurement feel bothersome. be able to. Moreover, when the forgetting excretion determination means determines that the excretion behavior has been forgotten, the notifying means informs the resident that the excretion behavior has been forgotten. And can encourage residents to excrete.

Further, since the excretion behavior cannot be detected before the predetermined time interval has elapsed since the previous detection , it can be determined that the excretion behavior has been forgotten.

According to the second aspect of the present invention, if the entry detecting means detects entry into the toilet and detects the excretion action, and the excretion action scheduled in the action schedule information cannot be detected, the excretion action forgetting determination means is excreted. Since it is determined that the person has forgotten the action and the resident himself does not need to make any measurement to detect the forgetting the excretion action, the resident is surely detected to forget the excretion action without making the measurement feel bothersome. be able to. Moreover, when the forgetting excretion determination means determines that the excretion behavior has been forgotten, the notifying means informs the resident that the excretion behavior has been forgotten. And can encourage residents to excrete. Furthermore, since the excretion behavior was not detected more than the predetermined number of times during the predetermined time period, it can be determined that the excretion behavior has been forgotten.

According to the invention of claim 3 , if neither the excretion behavior of urine and the excretion behavior of stool, which are respectively scheduled in the behavior schedule information, can be detected, it can be determined that the excretion behavior has been forgotten.

  When the living support notification system according to the present invention detects the excretion behavior performed by a single resident in the residence and determines that the resident has forgotten to excrete, the resident or the resident's family or resident An embodiment of a life support notification system will be described below with reference to the drawings.

(Embodiment 1)
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a schematic system configuration diagram of the first embodiment, and a control device 1 installed in a room where a resident spends a lot of time, for example, a living room R1 in which a television (TV) 2 is placed, and a toilet R2. A human sensor 4 that is installed in the toilet R2 to detect entry into the toilet R2 and a wireless transmitter 3 that is installed in the toilet R2 and wirelessly transmits a human body detection signal from the human sensor 4 to the control device 1 As prepared.

  The human sensor 4 includes a pyroelectric infrared detection element that detects the presence of a person in the detection area by detecting heat rays emitted from the human body, and an infrared detection element that detects heat rays from the detection area set in the toilet R2. When the amount of light received by the heat ray changes due to the movement of a person entering the toilet R2, a human body detection signal composed of a voltage signal is output to the wireless transmission device 3.

  As shown in the block diagram of FIG. 2, the wireless transmission device 3 performs A / D conversion on an input signal from the CPU 30 that performs overall control of the wireless transmission device 3 and the human sensor 4 and outputs the signal to the CPU 30. / D conversion unit 31, transmission data storage unit 32 that temporarily stores transmission data to be transmitted to the control device 1, and data stored in the transmission data storage unit 32, which is composed of a low-power wireless communication module, modulates the antenna 33a. And a wireless unit 33 that wirelessly transmits to the control device 1 via The CPU 30 of the wireless transmission device 3 constantly monitors the output of the A / D conversion unit 31. When a human body detection signal is input from the human sensor 4, the human body detection data is stored in the transmission data storage unit 32. The human body detection data stored in the transmission data storage unit 32 is wirelessly transmitted from the wireless unit 33.

  As shown in the block diagram of FIG. 3, the control device 1 includes a CPU 10 that performs overall control and a wireless unit that transmits and receives a radio signal (radio wave signal) via an antenna 11a, which includes a low-power radio communication module. 11, the reception data storage unit 12 that stores the reception data received by the wireless unit 11, and the number of times that the human sensor 4 of the toilet R 2 reacts to a person based on the reception data stored in the reception data storage unit 12 ( A human sensor response number storage unit 13 that stores the number of detections), a human sensor reaction threshold value storage unit 14 that stores a threshold value of the response number of the human sensor 4, and a reference value for the time interval of excretion behavior (hereinafter, excretion) A schedule interval time)) registered in advance, an excretion prompting display time storage unit 16 for storing a time when a display prompting the excretion action is detected when forgetting to excretion is detected, HDMI (High Definition Multimedia Interface) standard communication with HDMI 2, HDMI control data storage 18 for storing control data to be output from the HDMI communication unit 17 to the television 2, and HDMI communication unit An HDMI AV data storage unit 19 that stores video and audio signals (AV data) to be output from the TV 17 to the television 2 and an RTC (Real Time Clock) 20 that is a clocking means for clocking the current time are provided. In addition, in the HDMI AV data storage unit 19 of the control device 1, “It seems that you have not been in the toilet for a while” as notification data (image data and audio data) to be output to the television 2 in order to notify the user of forgetting to excrete. And a voice message with the content “Looks like you have n’t been in the bathroom for a while” is registered in advance.

  In the control device 1, when the wireless unit 11 receives the wireless signal transmitted from the wireless transmission device 3, the received data is demodulated into human body detection data and temporarily stored in the received data storage unit 12. The CPU 10 of the control device 1 increments the number of reactions of the human sensor 4 at a predetermined time interval (for example, every 1 minute) every time human body detection data is stored in the received data storage unit 12. The number of reactions (detection number) of the human sensor 4 is obtained and stored in the human sensor response number storage unit 13. Table 1 below shows the configuration of data stored in the motion sensor response count storage unit 13, and the count value of the response count of the motion sensor 4 is stored at intervals of 1 minute from 00:00 to 24:00:00 on that day. Yes.

  By the way, this system detects whether or not excretion behavior has been performed among the living activities performed by the resident, and if it has forgotten to perform excretion behavior, informs the resident of forgetting behavior of excretion behavior. Although it is aimed, it is difficult to detect that the excretion action is actually performed. Therefore, the CPU 10 of the control device 1 estimates that the resident is performing the excretion behavior by detecting the entry into the toilet R2 as an event that occurs with the excretion behavior, and detects the excretion behavior last time. It is determined that the excretion behavior has been forgotten if the excretion behavior cannot be detected until a predetermined scheduled excretion interval time (for example, 3 hours) elapses from the time when the excretion has occurred.

  That is, the CPU 10 of the control device 1 compares the number of reactions at each time interval stored in the human sensor response number storage unit 13 with the threshold value stored in the human sensor response threshold value storage unit 14, and the number of reactions is If it is equal to or greater than the threshold, it is determined that excretion is being performed because the occupancy state continues. Here, the entrance sensor is configured to detect entry into the toilet R2 by the human sensor 4, and the excretion detector is configured by the CPU 10 of the control device 1.

  And CPU10 which is an excretion action forget determination means will determine with excretion action being forgotten if the excretion action planned by action schedule information cannot be detected based on the detection result of excretion action and the time measured by RTC20. In this embodiment, since the information of the excretion action time interval (exclusion schedule interval time) is registered in the action schedule information storage unit 15 as the action schedule information, the CPU 10 of the control device 1 from the time when the excretion action was detected last time. If the excretion behavior cannot be detected before the scheduled excretion interval time stored in the action schedule information storage unit 15 elapses, it is determined that the resident has forgotten the excretion behavior, and the dwelling operation is forgotten. Notifying people.

Here, the process of detecting forgetting to excretion behavior by detecting the forgetting to excretion behavior by this system will be described based on the flowchart of FIG .
The CPU 10 of the control device 1 constantly monitors the input from the wireless unit 11. When the wireless unit 11 receives a wireless signal from the wireless transmission device 3, the human body detection signal obtained by demodulating the received data is received data. While being stored in the storage unit 12, based on the human body detection signal stored in the received data storage unit 12, the number of reactions per minute of the human sensor 4 is incremented and stored in the human sensor response number storage unit 13. ing.

  In addition, the CPU 10 of the control device 1 starts the determination process of forgetting to excrete at regular time intervals (for example, every minute), and first refers to the human sensor reaction frequency storage unit 13 (process S1) to excrete from the current time. It is determined whether or not there is a time zone in which the number of reactions per minute exceeds a predetermined threshold in the period up to the scheduled interval time (process S2).

  Here, if there is a time slot in which the number of reactions is equal to or greater than the threshold, the CPU 10 of the control device 1 determines that the excretion action has been performed before the scheduled excretion interval time elapses, and ends the determination process.

  On the other hand, if there is no time zone in which the number of reactions is greater than or equal to the threshold value in the determination of step S2, the CPU 10 of the control device 1 determines that the resident has forgotten to excrete, and has notified that the previous behavior has been forgotten. It is determined whether or not minutes have passed (processing S3). Here, if 30 minutes have passed since the previous notification, the CPU 10 of the control device 1 has the television 2 turned on by causing the HDMI communication unit 17 to communicate with the television 2. It is determined whether or not (processing S4). If the power of the television 2 is on, the CPU 10 of the control device 1 reads out the notification data for notifying the forgetting of excretion action from the HDMI AV data storage unit 19 and sets the television 2 to the HDMI input display mode. The control data to be switched is read from the HDMI control data storage unit 18, the control data and the notification data are transmitted from the HDMI communication unit 17 to the television 2, and a message that prompts the television 2 to go to the toilet with video or audio is output (processing) S5). Thereafter, the CPU 10 of the control device 1 prompts the excretion of the time at which the notification operation is performed, prompts the excretion as the display time, stores it in the display time storage unit 16 (process S6), and ends the determination process. In general, it is considered that elderly people watch TV for a long time, so this system uses the TV 2 as a notification means. However, in the case of a resident who has a long time to listen to the radio, the radio is notified. It can be used as a means, and in the case of a resident who spends a long time in a specific place in the room, a notification device such as a speaker or a display is installed in the place where the resident is long, and a human sensor detects the location. If it is detected that there is a resident, the notification device may be used to notify the user of forgetting action. Moreover, although the control apparatus 1 is performing alerting | reporting operation | movement with respect to a resident, it may be made to transmit a notification message to the mobile phone which the visitor caregiver who performs a visitor care of a resident's family or a resident, for example. Good.

  Further, when 30 minutes have not elapsed since the previous display in the determination process of S3, or when the power of the television 2 as the notification unit is turned off, the CPU 10 of the control device 1 determines without performing the notification operation. The process ends.

  As described above, in the life support notification system of the present embodiment, the CPU 10 of the control device 1 compares the number of reactions per minute of the human sensor 4 with a predetermined threshold, and if the number of reactions is equal to or greater than the threshold, Since there is a person in the toilet R2, it is determined that the excretion action has been performed. Then, the CPU 10 determines that the resident has forgotten to perform the excretion behavior if no excretion behavior is detected while the predetermined scheduled excretion interval time elapses, and the resident is in order to detect forgetting the excretion behavior. Since it is not necessary to carry out any measurement by itself, it is possible to reliably detect forgetting excretion behavior without making the resident feel bothersome of the measurement. In addition, when the CPU 10 of the control device 1 determines that the excretion behavior has been forgotten, the television 2 is used to notify the resident of forgetting the excretion behavior by means of text or a voice message. Can be noticed that the resident can be encouraged to excrete.

  If the excretion behavior cannot be detected while the predetermined excretion interval time elapses, the CPU 10 of the control device 1 determines that the excretion behavior is forgotten and performs a notification operation, and then can detect the excretion behavior. Since the notification operation is repeatedly performed at a predetermined notification interval (for example, every 30 minutes), the residents can be surely informed that they have forgotten to excrete and can be more surely encouraged to go to the toilet. .

  In the present embodiment, the time interval of excretion action (estimated excretion time) determined by the resident or the caregiver of the resident based on the life rhythm of the resident is stored in the action schedule information storage unit 15 in advance as action schedule information. If the CPU 10 of the control device 1 cannot detect the excretion behavior between the previous detection and the time interval of the excretion behavior elapses, that is, the excretion behavior from the current time to the time interval before the excretion behavior. If it is not detected, it is determined that the person has forgotten to excrete, but the action schedule information is not intended to limit the time interval of the excretion action, and the time information on which the excretion action is performed as the action schedule information If the information including at least one of the number of times excretion behavior is performed in a predetermined time zone is registered, and the excretion behavior scheduled by the action schedule information cannot be detected, the resident will excrete It may be determined that have forgotten the dynamic.

  For example, according to the life rhythm of the resident, information on a time zone assuming a time zone in which the resident or the caregiver of the resident performs excretion behavior is stored in advance in the action schedule information storage unit 15 as action schedule information and controlled. If the CPU 10 of the device 1 cannot detect the excretion behavior in the time zone stored in the action schedule information storage unit 15, it may be determined that the user has forgotten to perform the excretion behavior. Further, assuming the number of times that a resident or a caregiver of the resident is supposed to perform excretion behavior in a predetermined time zone (for example, 24 hours a day) according to the life rhythm of the resident, the scheduled number of times is set as action schedule information. It may be stored in advance in the action schedule information storage unit 15, and if the CPU 10 of the control device 1 cannot detect the excretion action more than the predetermined number of times in a predetermined time zone, it may be determined that the excretion action has been forgotten.

(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a block diagram of the control device 1. In the control device 1 of the first embodiment, the time interval of excretion action including both urine and stool is stored in the action schedule information storage unit 15 as action schedule information. On the other hand, in the present embodiment, a urine scheduled interval storage unit 15a that stores a urine scheduled interval time (for example, 3 hours) as a urine time interval as action schedule information for urine, and a stool that is a stool time interval. The control device 1 is provided with a stool scheduled interval storage unit 15b that stores scheduled interval time (for example, 24 hours) as action schedule information for stool. In addition, it replaces with the action schedule information memory | storage part 15, and since it is the same as that of the life assistance alerting | reporting system of Embodiment 1 except providing the urine schedule interval storage part 15a and the stool schedule interval storage part 15b in the control apparatus 1, it is common. Constituent elements are denoted by the same reference numerals and description thereof is omitted.

  The CPU 10 of the control device 1 compares the number of reactions per minute stored in the human sensor reaction number storage unit 13 with a predetermined threshold, and if the number of reactions is equal to or greater than the threshold, a person is present in the toilet R2. However, if it is determined that the person is in the room, excretion behavior is determined by comparing the length of time during which the entry state is continuously detected with a predetermined threshold time. Is a urine or stool. That is, since the stool requires a longer time than the urine, the CPU 10 determines that the excretion action is stool if the time during which the entering state is continuously detected is longer than the threshold time.

  Then, the CPU 10 of the control device 1 waits until the urine time interval stored in the urine scheduled interval storage unit 15a elapses based on the detection result of the excretion behavior (urine or stool) and the RTC time. If the urine excretion behavior cannot be detected and the stool excretion behavior cannot be detected before the stool excretion time stored in the stool scheduled interval storage unit 15b elapses, judge.

  Here, for example, 24 hours are registered as the stool time interval in the stool scheduled interval storage unit 15b, so the human sensor response number storage unit 13 stores data of the number of reactions from the current time to 24 hours ago. It is necessary to keep it. Table 2 below shows the configuration of data stored in the motion sensor response count storage unit 13, and the number of responses of the motion sensor 4 is stored at intervals of 1 minute from 00:00 to 24:00:00 on the previous day and that day. When the CPU 10 finishes storing the data from 23:59 to 24:00:00 of the day in the human sensor response number storage unit 13, it overwrites all the data of the number of reactions for the day with the data for the previous day, Prepare for storage of data for the next day. In addition, since it is necessary to store the data from the present time to the time before the stool time interval in the human sensor response number storage unit 13, the time interval of the stool is longer than 24 hours and less than 48 hours. If it is set, an area for storing the data for the day before last is prepared in the human sensor response number storage unit 13, and data from 23:59 to 24:00:00 is stored in the human sensor response number storage unit 13. When the data is stored, the data on the number of reactions for the current day and the previous day may be transferred to the data storage areas for the previous day and the previous day.

Below, the process which detects the forgetting to do excretion action by this system and detects the forgetting to do excretion action is demonstrated based on the flowchart of FIG .
The CPU 10 of the control device 1 constantly monitors the input from the wireless unit 11. When the wireless unit 11 receives a wireless signal from the wireless transmission device 3, the human body detection signal obtained by demodulating the received data is received data. While being stored in the storage unit 12, based on the human body detection signal stored in the received data storage unit 12, the number of reactions per minute of the human sensor 4 is incremented and stored in the human sensor response number storage unit 13. ing.

  In addition, the CPU 10 of the control device 1 starts the forgetting excretion determination process at regular time intervals (for example, every minute). First, a period T1 from the current time to the urinal scheduled interval time (3 hours before the current time). With reference to the data stored in the human sensor response number storage unit 13 (process S11), it is determined whether or not there is a time zone in which the number of reactions per minute exceeds a predetermined threshold in the period T1 (process S11). S12). Here, if there is no time zone in which the number of reactions is equal to or greater than the threshold, the CPU 10 of the control device 1 determines that no urine is being performed within the period T1, and sets the urine prompting request flag (processing S13). ), The urine determination process is terminated. On the other hand, if there is a time slot in which the number of reactions is equal to or greater than the threshold, the CPU 10 of the control device 1 determines that urine has been performed within the period T1, and ends the urine determination process.

  Next, the CPU 10 of the control device 1 refers to the stored data in the human sensor response number storage unit 13 in a period T2 from the current time to the scheduled stool interval time (24 hours before the current time) (processing S14), It is determined whether or not there are three or more consecutive time periods in which the number of reactions per minute exceeds a predetermined threshold in the period T2 (processing S15). Here, if the time period in which the number of reactions is equal to or greater than the threshold is not continuously three times or more, the CPU 10 of the control device 1 determines that no stool is performed within the period T2, and sets the urination prompt request flag. After (process S16), the stool determination process is terminated. On the other hand, if the time period in which the number of reactions is equal to or greater than the threshold is 3 or more times consecutively, that is, if the time during which the entry state is continuously detected is equal to or greater than the threshold time (3 minutes), the CPU 10 of the control device 1 It is determined that stool has been performed within the period T2, and the stool determination process is terminated.

  When the urine and stool determination process ends, the CPU 10 of the control device 1 determines whether or not 30 minutes have elapsed since the previous notification (process S17), and the HDMI communication unit 17 and the television 2 To determine whether or not the TV 2 is turned on (process S18), 30 minutes have passed since the previous notification, and the TV 2 is turned on. In this case, based on the values of the urination prompting request flag and the urination prompting request flag, it is determined whether there is a request for urination prompting request and / or a urination prompting request, or there is no request (processing) S19 to S21). Here, when there is both a urination prompting request and a urination prompting request, the CPU 10 of the control device 1 prompts the stool and urine from the HDMI AV data storage unit 19 as a message to be notified to the television 2 (for example, “There seems to be no stool” If there is only a urgent prompting request, a message prompting the stool from the HDMI AV data storage unit 19 (for example, “stool”) is selected. If there is only a urination prompting request, a message prompting urination from the HDMI AV data storage unit 19 (for example, “Do not stay in the toilet for a while”) is selected (processing S23). "" Is selected (process S24).

  When the notification message is selected as described above, the CPU 10 of the control device 1 reads out the control data for switching the television 2 to the display mode of the HDMI input from the HDMI control data storage unit 18, and the selected notification message and control data are read out. Is transmitted from the HDMI communication unit 17 to the television 2 and a predetermined notification message is output from the television 2 by video or audio (processing S25). The data is stored in the storage unit 16 (process S26), and the determination process is terminated. In addition, when 30 minutes have not elapsed since the previous display in the determination process of S17, when the power of the television 2 is turned off in the determination process of S18, or in the determination process of S19 to S21, a urgent prompting request and urine When there is no prompt request, the CPU 10 of the control device 1 ends the determination process without performing the notification operation.

  In general, it is considered that elderly people watch TV for a long time, so this system uses the TV 2 as a notification means. However, in the case of a resident who has a long time to listen to the radio, the radio is notified. It can be used as a means, and in the case of a resident who spends a long time in a specific place in the room, a notification device such as a speaker or a display is installed in the place where the resident is long, and a human sensor detects the location. If it is detected that there is a resident, the notification device may be used to notify the user of forgetting action. Moreover, although the control apparatus 1 is performing alerting | reporting operation | movement with respect to a resident, it may be made to transmit a notification message to the mobile phone which the visitor caregiver who performs a visitor care of a resident's family or a resident, for example. Good.

  As described above, in the life support notification system of the present embodiment, the CPU 10 of the control device 1 compares the number of reactions per minute of the human sensor 4 with a predetermined threshold, and if the number of reactions is equal to or greater than the threshold, Since there is a person in the toilet R2, it is determined that an excretion action has been performed. Further, if the time for continuously detecting the entry state is equal to or longer than the threshold time, it is determined to be stool, and if it is shorter than the threshold time, it is determined to be urine. Then, the CPU 10 determines that the resident has forgotten to urinate if the excretion behavior of the urine cannot be detected while the predetermined urine scheduled time interval elapses, and the predetermined stool scheduled time interval elapses. If the stool excretion behavior cannot be detected, it is determined that the resident has forgotten to take a stool, and the resident needs to make some measurement to detect forgetting the urination or stool excretion Therefore, it is possible to reliably detect forgetting excretion behavior for each of the urine and the stool without causing the residents to feel troublesome in the measurement. Moreover, when the CPU 10 of the control device 1 determines that the excretion behavior has been forgotten, a notification message that prompts only stool, only urine, or both stool and urine is output from the television 2 by text or voice, so It is possible to notice that the person has forgotten to excrete, and can encourage the resident to perform the excretion action.

Further, the CPU 10 of the control device 1 determines that the excretion behavior is forgotten and performs a notification operation if the excretion behavior of the urine and the stool is not detected while the predetermined scheduled urination interval time and the scheduled stool interval elapse. Since the notification operation is repeatedly performed at a predetermined notification interval (for example, every 30 minutes) until the excretion behavior can be detected thereafter, the resident is surely informed of forgetting to excrete and goes to the toilet. Can be more surely encouraged.
In this life support notification system, the action schedule information is information of a time zone in which excretion behavior is assumed to be performed according to the living rhythm of the resident. If it cannot be detected, it is determined that the excretion behavior is forgotten. Since the excretion behavior could not be detected in the time period expected from the resident's life rhythm, it can be determined that the excretion behavior has been forgotten.
