Description

  The present invention relates to a health condition estimation system, a health condition estimation device, a health condition estimation method, and a computer-readable recording medium on which a program for realizing these is recorded.

  In recent years, the elderly living alone has increased rapidly. In order for a family living away from the elderly to check the health of the elderly, it is necessary to visit the elderly's residence or call the elderly. However, frequent visits to senior citizens' homes are a time and financial burden for families. In addition, it is difficult to reliably check the health status of elderly people by phone alone. Furthermore, if the elderly person does not answer the phone when the elderly person is absent, the family will feel extra anxiety.

  In order to reduce the burden on the family as described above, it is conceivable to arrange an emergency call device or a device for notifying the family that the patient is healthy in the residence of the elderly. However, in this case, the elderly person's own operation is required, and the health condition of the elderly person may not be properly grasped due to forgetting to push or the like. Therefore, conventionally, development of a system for appropriately grasping the health condition of the elderly has been promoted.

  For example, Patent Document 1 discloses a system in which a plurality of sensors are arranged in a house and life activity data of elderly people detected by the sensors is stored. According to this system, for example, it is possible to grasp the time when an elderly person flushed toilet water, the time when a telephone call was made, and the like. Thereby, the living behavior of the elderly can be confirmed.

In addition, according to the health condition estimation system, the health condition estimation apparatus, and the health condition estimation method according to the present embodiment, the resident's moving speed (for example, walking speed) can be calculated as an index representing the resident's health condition. In other words, the health condition estimation system, the health condition estimation apparatus, and the health condition estimation method according to the present embodiment, in other words, a movement speed calculation system, a movement speed calculation apparatus, It is a moving speed calculation method.

[System configuration]
First, the configuration of the health condition estimation system will be described with reference to FIG. FIG. 1 is a diagram showing a schematic configuration of a health condition estimation system according to an embodiment of the present invention.

  Referring to FIG. 1, a health condition estimation system (hereinafter also simply referred to as “estimation system”) 10 according to the present embodiment includes a plurality (two in the present embodiment) of movement detection units MD1 and MD2, and at least one. Use detection unit UD and movement speed calculation unit 11. As will be described later, the estimation system 10 is provided in a residence having a toilet room, for example.

  In the present embodiment, each of the movement detection units MD1 and MD2 is a movement detection device that detects the movement of a resident in the residence and outputs a movement detection signal. In the present embodiment, the use detection unit UD is a use detection device that detects use of a toilet room by a resident and outputs a use detection signal. Hereinafter, the movement detection signal and the usage detection signal are also simply referred to as detection signals.

  As the movement detection device and the usage detection device, for example, a human sensor that detects a person using infrared rays, ultrasonic waves, visible light, or the like can be used. A pressure sensor may be used as each of the movement detection device and the usage detection device. In this case, a pressure sensor may be provided on the floor, and movement of the resident and use of the toilet room by the resident may be detected based on a change in pressure detected by the pressure sensor. Moreover, you may detect use of the toilet room by a resident based on the amount of water consumption in a toilet room using a flow sensor etc. as a usage detection apparatus.

  The movement speed calculation unit 11 is based on the detection signal output from the movement detection units MD1 and MD2 and the distance information regarding the distance between the movement detection units MD1 and MD2 set in advance, between the movement detection units MD1 and MD2. Calculate the movement speed of the resident. A method for calculating the moving speed will be described later.

  FIG. 2 is a diagram illustrating an example of a residence in which the estimation system 10 is installed. A residence 50 shown in FIG. 2 has a corridor R1, a toilet room R2, a living room R3, a kitchen R4, a bedroom R5, and an entrance hall R6. In the example of FIG. 2, the movement detection units MD1 and MD2 are disposed in the hallway R1. The use detection unit UD is disposed in the toilet room R2. The moving speed calculation unit 11 is disposed in the living room R3 as a constituent element of a health state estimation device 100 (see FIG. 4) described later, for example. In the example of FIG. 2, the movement detection unit MD1 is arranged on one side of the corridor R1 so that the movement detection unit MD2 is located near the toilet room R2 as compared to the movement detection unit MD1. A movement detection unit MD2 is arranged on the other side. Hereinafter, assuming that the estimation system 10 is arranged as illustrated in FIG. 2, an example of a method for calculating the movement speed by the movement speed calculation unit 11 will be described.

  FIG. 3 is a diagram illustrating an example of the time when the movement detection units MD1 and MD2 detect the movement of the resident and the time when the use detection unit UD detects the use of the toilet room R2 by the resident in the estimation system 10 of FIG. is there. In the present embodiment, the “detected time” is, for example, the time at which the movement detection units MD1 and MD2 and the usage detection unit UD output detection signals.

  In the example of FIG. 3, use detection signals are output from the use detection unit UD at 9:22:38 and 10:42:21, respectively. That is, in the example of FIG. 3, the use detection unit UD detects the use of the toilet room R2 by the resident at 9:22:38 and 10:42:21, respectively.

  In the present embodiment, when calculating the occupant's movement speed, the movement speed calculation unit 11 first identifies “a combination of detection times of the movement detection unit”. Specifically, the movement speed calculation unit 11 outputs the movement detection signal before and after the use detection signal is output when the use detection signal is output from the use detection unit UD. The detection times of the detection units MD1 and MD2 are specified as “a combination of detection times of the movement detection unit”. The “movement detection signal output one and two times before the use detection signal is output” is a time series of a plurality of detection signals output from the use detection unit UD and the movement detection units MD1 and MD2. Means a movement detection signal one before and two times before the use detection signal.

  In the example illustrated in FIG. 3, the movement speed calculation unit 11 determines that the detection time of the movement detection unit MD2 is 9:22:35 and the detection time of the movement detection unit MD1 is 9:22:32. Specified as “combination of detection times of parts”. Further, the movement speed calculation unit 11 sets the detection time of the movement detection unit MD2: 10:42:19 and the detection time of the movement detection unit MD1: 10:42:15 as “the detection time of the movement detection unit. Specified as “combination”. That is, in the example of FIG. 3, the movement speed calculation unit 11 specifies two sets of “combination of detection times of the movement detection unit”.

  Next, the movement speed calculation unit 11 calculates the elapsed time from detection by one movement detection unit to detection by the other movement detection unit for each “combination of detection times of the movement detection unit”. In the example of FIG. 3, the movement speed calculation unit 11 sets the difference between the detection time of the movement detection unit MD1 and the detection time of the movement detection unit MD2 as the elapsed time for each “combination of detection times of the movement detection unit”. calculate. Specifically, for the first set of “movement detection unit combination”, the elapsed time is calculated as 3 seconds, and for the second set of “movement detection unit detection time” The elapsed time is calculated as 4 seconds.

  Next, for each “combination of detection times of the movement detection unit”, the movement speed calculation unit 11 is based on the calculated elapsed time and distance information regarding the distance between the movement detection units MD1 and MD2 set in advance. The movement speed of the resident between the movement detection units MD1 and MD2 is calculated. For example, it is assumed that information indicating that the distance between the movement detection units MD1 and MD2 is 3 m is set in advance as distance information. In this case, in the example of FIG. 3, the moving speed of the resident is calculated as 1 m / s for the first set of “combination time detection of the movement detection unit”, and the second set “combination of detection time of the movement detection unit” "Is calculated as 0.75 m per second. Although details will be described later, the distance information may not indicate the actual distance between the movement detection units MD1 and MD2.

  As described above, in the present embodiment, when the usage detection signal is output from the usage detection unit UD, the movement speed calculation unit 11 detects the movement one and two times before the usage detection signal is output. The movement speed of the resident is calculated based on the detection times of the pair of movement detection units MD1 and MD2 that output the signals. That is, in this embodiment, the movement speed calculation unit 11 calculates the movement speed of the resident based on the detection time of the movement detection units MD1 and MD2 that have detected the movement of the resident toward the toilet room R2.

  Here, in general, when a resident heads for the toilet room R2 to add work, it is considered that there is almost no stopping on the way or finishing other things on the way. For this reason, when a resident heads for toilet room R2, it is thought that it moves between movement detection part MD1, MD2 at the substantially constant speed according to a resident's ability (walking ability). Therefore, in the estimation system 10 according to the present embodiment, the moving speed when the resident moves toward the toilet room R2 is calculated as an index representing the resident's health condition. Thereby, a resident's health condition (for example, walking ability) can be grasped exactly.

  Moreover, in the estimation system 10, the movement speed calculation part 11 calculates a resident's movement speed based on the detection signal of movement detection part MD1, MD2 and the use detection part UD. For this reason, it is not necessary for the resident to carry a device or the like for calculating the moving speed, and it is not necessary for the resident to perform a special operation or the like in order to calculate the moving speed. Thereby, a burden of a resident can be reduced sufficiently.

  As described above, according to the estimation system 10 according to the present embodiment, it is possible to accurately grasp the health condition of the resident while reducing the burden on the resident.

  Next, a specific configuration of the health condition estimation system will be described. FIG. 4 is a block diagram specifically showing the configuration of the health condition estimation system 10 according to the embodiment of the present invention.

  Referring to FIG. 4, in the present embodiment, estimation system 10 includes a plurality of movement detection units MD1 to MD5, a usage detection unit UD, and a health state estimation device (hereinafter also simply referred to as “estimation device”) 100. ing. In the present embodiment, the plurality of movement detection units MD1 to MD5 and the usage detection unit UD are connected to the estimation device 100 by, for example, a wired or wireless network. As described above, the movement detection units MD1 and MD2 are movement detection devices that detect movement of a resident and output a movement detection signal. Similarly, the movement detection units MD3 to MD5 are movement detection devices that detect movement of a resident and output a movement detection signal. In addition, as described above, the use detection unit UD is a use detection device that detects use of a toilet room by a resident and outputs a use detection signal.

  Hereinafter, before explaining the specific configuration of the estimation apparatus 100, an installation example of the estimation system 10 in a residence will be briefly described. FIG. 5 is a diagram illustrating a specific installation example of the estimation system 10 in the residence 50.

  In the installation example of FIG. 5, similarly to the installation example of FIG. 2, the movement detection units MD1 and MD2 are arranged in the corridor R1, and the use detection unit UD is arranged in the toilet room R2. The movement detection unit MD3 is arranged in the living room R3, the movement detection unit MD4 is arranged in the kitchen R4, and the movement detection unit MD5 is arranged in the bedroom R5. The estimation apparatus 100 is arranged in the living room R3.

  Hereinafter, the configuration of the estimation apparatus 100 will be specifically described. In the following, in order to facilitate understanding of the function of the estimation apparatus 100, the function of the estimation apparatus 100 will be described assuming that the estimation system 10 is installed as shown in FIG. However, the installation example of the estimation system 10 illustrated in FIG. 5 is merely an example, and the arrangement of each component of the estimation system 10 can be changed as appropriate.

  With reference to FIG. 4, in this embodiment, in addition to the above-mentioned moving speed calculation unit 11, the estimation apparatus 100 further includes a data collection unit 12, a timer 13, a detection information storage unit 14, a placement information storage unit 15, and a use. A number counting unit 16, a total detection number counting unit 17, a speed information storage unit 18, a number information storage unit 19, an alert unit 20, and a transmission unit 21 are provided.

  Detection signals output from the movement detection units MD1 to MD5 and the use detection unit UD are input to the data collection unit 12. The data collection unit 12 acquires date and time information from the timer 13 when a detection signal is input from any of the movement detection units MD1 to MD5 and the usage detection unit UD. Further, the data collection unit 12 causes the detection information storage unit 14 to store detection information indicating that the detection signals are output from the movement detection units MD1 to MD5 and the use detection unit UD. The detection information includes, for example, detection times of the movement detection units MD1 to MD5 and the usage detection unit UD. In the present embodiment, the data collection unit 12 uses the time when the detection signal is input to the data collection unit 12 as the time when any of the movement detection units MD1 to MD5 detects the movement of the resident or the use of the toilet room R2 by the resident. Is stored in the detection information storage unit 14 as the time when the use detection unit UD detects it. Thereby, as shown in FIG. 6, for example, the detection times of the movement detection units MD1 to MD5 and the usage detection unit UD are stored in the detection information storage unit 14 as detection information. In FIG. 6, in order to make the explanation easy to understand, the detection by the movement detection unit MD3 at 18:45:54 is the first detection, and the detection order by the movement detection units MD1 to MD5 and the use detection unit UD. Are shown as the detection order.

  In addition, movement detection part MD1-MD5 may have a function which transmits the time which detected the movement of a resident to the data collection part 12 with a detection signal. Moreover, you may have a function in which the use detection part UD transmits the time which detected use of toilet room R2 by a resident to the data collection part 12 with a detection signal. In these cases, the timer 13 may not be provided in the estimation apparatus 100.

  In the arrangement information storage unit 15, distance information related to the distance between the movement detection units is stored in advance. The distance information is information indicating the distance between the movement detection units, for example, as shown in FIG.

  In the present embodiment, the movement speed calculation unit 11 is based on the detection times of the movement detection units MD1 to MD5 and the distance information described above, and the movement speed of a resident who passes between any two movement detection units. Is calculated. In the present embodiment, the movement speed calculation unit 11 calculates the movement speed of the resident between the movement detection units based on the detection times of the two different movement detection units that sequentially detect the movement of the resident and the distance information. calculate.

  For example, in the estimation system 10 arranged as shown in FIG. 5, the movement speed calculation unit 11 includes the movement detection units MD1 and MD2, the movement detection units MD1 and MD3, the movement detection units MD1 and MD4, and the movement detection unit MD1. , MD5, movement detection units MD2 and MD3, and movement detection units MD3 and MD4, the movement speed of the resident is calculated.

  Specifically, in the example of FIG. 6, the first detection is performed by the movement detection unit MD3 at 18:45:54, and the second detection is performed by the movement detection unit MD4 at 18:45:58. ing. The elapsed time from the first detection to the second detection is 4 seconds. Referring to FIG. 7, the distance between movement detection unit MD3 and movement detection unit MD4 is 3 m. Therefore, the movement speed of the resident between the movement detection units MD3 and MD4 is calculated by the movement speed calculation unit 11 to be 0.75 m / s. Although detailed description is omitted, as described above, the movement speed calculation unit 11 calculates the movement speed of the resident for each combination of two different movement detection units that sequentially detect the movement of the resident.

  In the present embodiment, for example, even when two movement detection units detect the movement of a resident in order, the detection of the second movement detection unit (from the detection of the first movement detection unit (the previous detection)) ( If the elapsed time until the later detection is equal to or longer than a preset reference time, the moving speed calculation unit 11 stops calculating the moving speed. In the example of FIG. 6, the movement detection unit MD2 performs the eighth detection at 19:40:42, and the movement detection unit MD3 performs the ninth detection at 19:41:42. That is, the elapsed time from the detection of the first movement detection unit MD2 to the detection of the second movement detection unit MD3 is 60 seconds. Therefore, for example, when the preset reference time is 50 seconds, the movement speed calculation unit 11 performs the interval between the eighth detection by the movement detection unit MD2 and the ninth detection by the movement detection unit MD3. The calculation of the moving speed of residents in is stopped. Thereby, for example, when the elapsed time becomes longer due to a reason that the resident stops halfway, the calculation of the resident's movement speed by the movement speed calculation unit 11 is stopped. As a result, the actual moving speed (walking speed) of the resident can be calculated more appropriately.

  Note that the information stored in the arrangement information storage unit 15 may be an actual distance between the movement detection units (see FIG. 7) or other information regarding the distance between the movement detection units. For example, a value obtained by setting the distance between arbitrary movement detection units to 1 and normalizing the distance between other movement detection units may be stored in advance in the arrangement information storage unit 15 as distance information. In this case, the movement speed calculation unit 11 calculates the movement speed of the resident based on the normalized distance information.

  The moving speed calculation unit 11 further calculates the average moving speed of the resident for each preset first period (for example, 24 hours). In the present embodiment, the moving speed calculation unit 11 calculates the average moving speed of the resident by setting weights for each of a plurality of sections (the six sections described above) defined by the movement detection units MD1 to MD5, for example. . For example, the moving speed calculation unit 11 sets the average moving speed by setting the weight of the moving speed of the resident in the predetermined reference section among the plurality of sections described above to be larger than the weighting of the moving speed of the resident in the other sections. calculate. Specifically, in this embodiment, a section defined by two movement detection units that output a movement detection signal one time before and two times before the use detection signal is output is set as a reference section. A plurality of sections defined by a plurality of movement detection units that output movement detection signals two or more times before the use detection signal is output are set as the other sections.

  In this embodiment, “a plurality of movement detection units that output a movement detection signal two or more times before the use detection signal is output” means “two or more times before the use detection signal is output”. And a plurality of movement detection units that output a movement detection signal after the use detection signal was output last time. For example, in FIG. 6, the fifth (19:38:11) and sixth (19:38:15) movement detection signals are based on the 12th (20:48:57) use detection signal. Then, it is output two or more times before the use detection signal is output. However, the fifth (19:38:11) movement detection signal and the sixth (19:38:15) movement detection signal are immediately before the twelfth (20:48:57) use detection signal (the seventh). : 19:38:18) before the use detection signal is output. Therefore, the movement detection unit MD3 that outputs the movement detection signal at the fifth (19:38:11) and the movement detection unit MD2 that outputs the movement detection signal at the sixth (19:38:15) It does not correspond to “a plurality of movement detection units that output a movement detection signal two or more times before the signal is output”.

  By setting the weight of the moving speed of the resident in the plurality of sections as described above, the weighting of the moving speed of the resident in the section immediately before the resident arrives at the toilet room R2 is weighted. Can be larger. As described above, when the resident heads for the toilet room R2, it is considered that the resident moves between the movement detection units at a substantially constant speed corresponding to the resident's ability (walking ability). Therefore, by increasing the weight of the resident's moving speed in the section immediately before the resident arrives at the toilet room R2, the moving speed calculating unit 11 calculates the average moving speed more reflecting the actual walking ability of the resident. Can do.

  In the example of FIG. 6, the detection signals output in the seventh, twelfth, and nineteenth are the usage detection signals output by the usage detection unit UD. Therefore, the distance between the movement detection unit MD3 that outputs the detection signal at the fifth (19:38:11) and the movement detection unit MD2 that outputs the detection signal at the sixth (19:38:15) is the above reference. Set to interval. Further, the distance between the movement detection unit MD3 that outputs the detection signal at the tenth (20:48:51) and the movement detection unit MD2 that outputs the detection signal at the eleventh (20:48:54) is the reference. Set to interval. Further, the distance between the movement detection unit MD1 that outputs the detection signal at the 17th (23:31:36) and the movement detection unit MD2 that outputs the detection signal at the 18th (23:31:40) is the above reference. Set to interval. In the example of FIG. 6, when the moving speed calculation unit 11 calculates the average moving speed, the weight of the moving speed of the resident in the three reference sections is the resident's weight in the other sections (sections other than the three reference sections). It is set larger than the moving speed weight.

  As described above, in the present embodiment, the interval between two movement detection units that output the movement detection signal one time before and two times before the use detection signal is output is set as the reference section. Therefore, even in a section defined by the same two movement detection units, there are cases where the detection unit that outputs a detection signal thereafter sets the reference section and does not set the reference section. For example, when the movement detection units MD1 and MD2 output detection signals in order, and then the use detection unit UD outputs a detection signal, as described above, the movement detection units MD1 and MD2 are connected to each other. Set to the reference interval. On the other hand, when the movement detection units MD1 and MD2 output detection signals in order, and subsequently the movement detection unit MD3 outputs a detection signal, the movement detection units MD1 and MD2 are not included in the reference section. Not set.

  The movement speed calculation unit 11 stores the movement speed and the average movement speed calculated as described above in the speed information storage unit 18 as speed information. In addition, a signal indicating speed information is transmitted to the alert unit 20 and the transmission unit 21. In the present embodiment, the movement speed calculation unit 11 associates, for example, the section (combination of movement detection units) where the movement speed is calculated and the detection time of each movement detection unit, and sets the calculated movement speed to the speed information storage unit 18. Remember me.

  Based on the detection information stored in the detection information storage unit 14, the usage number counting unit 16 calculates the number of detections of the use detection unit UD in the preset second period. The number-of-uses counting unit 16 stores the calculated number of times of detection of the use detecting unit UD in the number-of-times information storage unit 19. In addition, the usage number counting unit 16 transmits a signal indicating the number of detections of the usage detection unit UD to the alert unit 20 and the transmission unit 21. The second period can be changed as appropriate according to the purpose. For example, when it is desired to measure the number of times the resident's toilet room R2 is used on a daily basis, the second period is set to 24 hours. For example, when it is desired to measure the number of times the resident uses the toilet room R2 at night, the second period is set to a predetermined time at night (for example, 23:00 to 4 o'clock).

  The total detection number counting unit 17 calculates the total number of detections of the movement detection units MD1 to MD5 and the usage detection unit UD in the preset third period based on the detection information stored in the detection information storage unit 14. . In the present embodiment, the total detection number counting unit 17 sets a weight for each detection unit, for example, and calculates the total number of detections of the movement detection units MD1 to MD5 and the usage detection unit UD. For example, the total detection number counting unit 17 sets the weighting of the detection number of a predetermined reference detection unit out of the movement detection units MD1 to MD5 and the usage detection unit UD larger than the weighting of the detection number of other detection units. The total number of detections is calculated. Further, for example, the total detection number counting unit 17 sets the detection number of the predetermined auxiliary detection unit out of the movement detection units MD1 to MD5 and the use detection unit UD to be smaller than the weighting of the detection number of the other detection units. The total number of detections is calculated. In the present embodiment, for example, the movement detection unit MD4 arranged in the kitchen R4 is set as the reference detection unit. Further, for example, the movement detection unit MD5 disposed in the bedroom R5 is set as the auxiliary detection unit.

  The total detection number counting unit 17 stores the total number of detections calculated as described above in the number information storage unit 19. Further, the total detection number counting unit 17 transmits a signal indicating the total number of detections to the alert unit 20 and the transmission unit 21. The third period is set to 24 hours, for example. Note that the third period can be appropriately changed according to the purpose, similarly to the second period.

  As described above, the speed information is stored in the speed information storage unit 18 by the moving speed calculation unit 11. The number-of-times information storage unit 19 stores number-of-times information related to the number of detections of the movement detection units MD1 to MD5 and the usage detection unit UD. Specifically, as described above, the number-of-times information storage unit 19 stores the number of detections of the use detection unit UD in the second period by the use number counting unit 16. Furthermore, as described above, the total number of detections of the movement detection units MD1 to MD5 and the usage detection unit UD in the third period is stored in the number information storage unit 19 by the total detection number counting unit 17 as described above.

  The alert unit 20 performs an alert based on information given from the moving speed calculation unit 11, the use count counter 16, and the total detection count counter 17. Specifically, the alert unit 20 generates an alert signal and transmits the alert signal to the transmission unit 21. Hereinafter, conditions for the alert unit 20 to generate an alert signal will be briefly described. The conditions for the alert unit 20 to generate an alert signal are not limited to the following examples, and can be changed as appropriate.

  In the present embodiment, the alert unit 20, for example, based on the speed information stored in the speed information storage unit 18, the average movement speed calculated in the past by the movement speed calculation unit 11 (the average movement speed in the past first period). ) Is averaged. Then, the alert unit 20 compares the calculated average value with the average moving speed transmitted from the moving speed calculating unit 11. That is, the alert unit 20 compares the average moving speed calculated this time by the moving speed calculating unit 11 with the average value of the average moving speeds calculated in the past by the moving speed calculating unit 11. When the difference between the average movement speed calculated this time and the average value of the average movement speeds calculated in the past exceeds the first threshold, the alert unit 20 generates an alert signal.

  The first threshold value is set to a predetermined value in advance according to, for example, the resident's health condition and walking ability. Note that the first threshold value may be calculated by the alert unit 20 based on, for example, the average moving speed calculated in the past by the moving speed calculation unit 11. Specifically, for example, a value that is a constant multiple of the standard deviation of the average moving speed calculated in the past by the moving speed calculating unit 11 may be set as the first threshold value.

  Moreover, the alert part 20 compares the average value of the average moving speed calculated as mentioned above with the resident's moving speed transmitted from the moving speed calculating part 11, for example. That is, the alert unit 20 compares the resident's moving speed in an arbitrary section calculated by the moving speed calculating unit 11 with the average value of the average moving speeds calculated by the moving speed calculating unit 11 in the past. When the difference between the moving speed of the resident in an arbitrary section and the average value of the average moving speed calculated in the past exceeds the second threshold, the alert unit 20 generates an alert signal. Although a detailed description is omitted, the second threshold value can be set in the same manner as the first threshold value described above. That is, the second threshold value may be set to a predetermined value according to, for example, the health condition of the resident and walking ability, and is a value calculated based on the average moving speed calculated by the moving speed calculating unit 11 in the past. (For example, a value that is a constant multiple of the standard deviation) may be set. Although detailed explanation is omitted, the difference between the average value of the movement speed calculated by the movement speed calculation unit 11 in the past and the movement speed of the resident transmitted from the movement speed calculation unit 11 exceeds the second threshold. The alert unit 20 may generate an alert signal. In this case, for example, the alert unit 20 may calculate the average value of the moving speed by setting a weight for each section, similarly to the case where the moving speed calculating unit 11 calculates the average moving speed.

  Further, the alert unit 20, for example, based on the number information stored in the number information storage unit 19, the number of detections of the use detection unit UD calculated by the use number counting unit 16 in the past (use detection in the past second period). The average value of the number of times of detection of the part UD is calculated. Then, the alert unit 20 compares the calculated average value with the number of detections of the use detection unit UD transmitted from the use number counting unit 16. That is, the alert unit 20 compares the number of detections calculated this time by the use number counting unit 16 with the average value of the number of detections calculated in the past by the use number counting unit 16. When the difference between the number of detections calculated this time and the average value of the number of detections calculated in the past exceeds the third threshold value, the alert unit 20 generates an alert signal.

  The third threshold value is set to a predetermined value in advance according to, for example, the health condition of the resident and walking ability. In addition, the third threshold value may be calculated by the alert unit 20 based on the number of detections calculated in the past by the use number counting unit 16, for example. Specifically, for example, a value that is a constant multiple of the standard deviation of the number of detections calculated in the past by the use number counting unit 16 may be set as the third threshold value.

  Further, for example, the alert unit 20 calculates the total number of detections (total number of detections in the past third period) calculated by the total detection number counting unit 17 in the past based on the number information stored in the number information storage unit 19. The average value is calculated. Then, the alert unit 20 compares the calculated average value with the total number of detection times transmitted from the total detection number counting unit 17. That is, the alert unit 20 compares the total number of detections calculated this time by the total detection number counting unit 17 with the average value of the total number of detections calculated in the past by the total detection number counting unit 17. When the difference between the total number of detections calculated this time and the average value of the total number of detections calculated in the past exceeds the fourth threshold, the alert unit 20 generates an alert signal.

  The fourth threshold value is set to a predetermined value in advance according to, for example, the resident's health condition and walking ability. Further, the fourth threshold value may be calculated by the alert unit 20 based on the total number of detections calculated by the total detection number counting unit 17 in the past, for example. Specifically, for example, a value that is a constant multiple of the standard deviation of the total number of detections calculated in the past by the total detection number counting unit 17 may be set as the fourth threshold value.

  The transmission unit 21 transmits the data transmitted from the moving speed calculation unit 11, the usage count counting unit 16, and the total detection count counting unit 17 to an external terminal (such as a personal computer, a smartphone, and a tablet terminal) (not shown) on the Internet. And so on over the network. Thus, for example, a family living away from the resident can use the external terminal to determine the resident's movement speed (walking ability), the number of times the toilet room R2 is used in a predetermined time zone (for example, at night), and the amount of activity. I can grasp it. As a result, the resident's family can accurately grasp the change in the resident's health condition (such as a decrease in physical fitness, the risk of injury or urine disease). The resident's activity amount can be estimated based on the total number of detections calculated by the total detection number counting unit 17, for example.

  Moreover, the transmission part 21 notifies an alert to the said external terminal by transmitting an alert signal, when an alert signal is input from the alert part 20. FIG. Thereby, the resident's family can easily recognize that the walking ability of the resident has changed, the number of times the toilet room R2 is used in a predetermined time zone, and a decrease in the amount of activity. Note that the transmission unit 21 may notify the alert by e-mail instead of transmitting an alert signal to the external terminal, for example.

It is determined that an alert signal is generated. On the other hand, the alert unit 20 stops the generation of the alert signal when none of the information input from the moving speed calculation unit 11, the use count counting unit 16, and the total detection count counting unit 17 satisfies the predetermined condition.

  When it determines with producing | generating an alert signal in step S6, the alert part 20 produces | generates an alert signal and transmits the produced | generated alert signal to the transmission part 21 (step S7).
