Description

Self-supporting index measuring device and method

The present invention relates to a self-supporting index measuring device and a self-supporting index measuring method for obtaining an index value representing the degree of self-supporting in a subject.

Those who need care such as nursing or nursing care due to illness, injury, and elderly people generally receive prescribed care by caregivers such as nurses and carers. The level of independence of the cared person varies. In the case of a cared person having a relatively low level of independence, it is desirable that the care is performed at the required timing of the care, for example, in order to prevent an accident. On the other hand, in the case of a relatively carer who has a relatively high level of independence, an excessive level of care that is too high may reduce the original independence (the original independence) by getting used to the level of care Not only there is a fear, but also the physical and psychological burden on the carer may be greater than the original burden. Therefore, it is desirable that care be performed at an appropriate level according to the level of independence of the care recipient, and for that purpose, it is desirable to measure and quantify the independence of the care recipient. The technique regarding such a measurement of self-supporting property is proposed by patent document 1, for example.

The state detection device disclosed in Patent Document 1 includes an imaging lens for imaging an image of a monitoring area, and light arranged on the imaging surface of the imaging lens to form a plurality of lines. A care receiver based on a sensor array, distance detection means for detecting a distance from an image signal output from the light sensor array to a detection target present in a monitoring area, and distance data detected by the distance detection means Calculating an amount of activity of the patient, and determining a state of abnormality when the amount of activity of the cared person decreases to a predetermined amount or less. And when the said state determination means detects a cared person, the movement amount per unit time is calculated from the detection position of this cared person, and the average value in the predetermined time of the calculated movement amount is said to be cared for Calculated as the amount of activity of

By the way, the amount of movement of the person to be cared (person to be measured) or the amount of activity based on the amount of movement is influenced by the size and layout of the room where the person to be cared is located. When the care recipient located in a relatively large room performs, for example, entering and exiting the room, opening and closing windows, toilets, etc. from bedding, the movement amount (activity amount) is Become more. On the other hand, the care recipient located in a relatively narrow room decreases the movement amount (activity amount) when carrying out the above-mentioned need. In addition, even for the care recipient located in a relatively large room, if the entry and exit doors, windows, washrooms and toilet facilities etc. are laid out (arranged) relatively close to the bedding, the movement The amount (activity amount) decreases. Therefore, as in the state detection device disclosed in Patent Document 1, the movement amount per unit time is simply calculated from the detection position of the care receiver, and the average value of the calculated movement amount in the predetermined time is taken as the cared person When calculated as the amount of activity of elderly people, even if the level of independence of the person being cared is the same, for example, the person being cared for in a relatively large room has a large amount of movement (amount of activity) The level of independence is highly appreciated, and the care recipient located in a relatively narrow room or the like is evaluated as low in level of independence as a result of the amount of movement (amount of activity) becoming smaller. For this reason, there is a possibility that the independence of the care receiver can not be properly determined by the amount of movement (the amount of activity).

In the present embodiment, the movement distance processing unit 222a sets the distance between the first and second positions when the person to be measured Ob moves from the first position in the room to a second position different from the first position. Measured as the movement distance of the subject. More specifically, the moving distance processing unit 222a measures the position of the subject Ob at predetermined time intervals, and measures the position of the subject Ob each time the subject Ob measured in the previous time. The distance between the position of the subject (previous position) and the position of the subject Ob measured this time (the present position) is obtained as a divided movement distance, and each divided movement obtained each time the position of the measured person Ob is measured By accumulating the distance from the first position to the second position, the movement distance of the person to be measured Ob from the first position to the second position is measured. More specifically, in the present embodiment, since the position of the subject Ob is obtained from the target image generated by the sensor device SU, the image notification communication signal transmitted from the sensor device SU is received at predetermined time intervals. The moving distance processing unit 222a obtains the position of the subject Ob based on the target image contained in the image notification communication signal, and the obtained position of the subject Ob is previously set to the first position. Or, it is determined whether or not it is the second position, and every time the position of the person to be measured Ob is determined, the previous position of the person to be measured Ob determined at the previous time to the current position of the person to be measured Ob determined at this time Is determined as the divided movement distance, and is determined each time the position of the measurement subject Ob is measured during the movement from the first position to the second position in the measurement subject Ob based on the determination result. By accumulating (sum) the division moving distance from the first position to the second position, determine the movement distance of the subject Ob from the first position to the second position.

The independence indicator processing unit 223a determines independence of the measurement subject Ob based on the movement distance of the measurement subject Ob determined by the movement distance processing module 222a and the predetermined standardized value stored in the standardization information storage unit 231a. The index value (index value of independence) which represents the degree of is calculated. In the first embodiment, the predetermined normalization value is a distance between the first and second positions (actual distance of physical space). For this reason, the self-supporting index processing unit 223a sets the moving distance of the subject Ob obtained by the measurement by the moving distance processing unit 222a as the first predetermined standardization value stored in the standardization information storage unit 231a. By dividing by the distance between the second position and the second position, an index value of independence in the subject Ob is obtained.

And in this embodiment, the said index value is totaled for every predetermined period set up beforehand. For this reason, the movement distance processing unit 222a sets one of the two points (the start point of the movement) as the first position each time the person to be measured Ob moves at two different points within a predetermined period. The movement distance of the subject Ob is measured with the other point of the two points (end point of the movement) as the second position, and the self-supporting index processing unit 223a makes the subject Ob different from each other within the predetermined period. An index value of independence in the subject Ob is obtained each time the vehicle moves to two points, and after the predetermined period ends, the sum of the index values of the independence thus obtained is the index value of the final independence in the predetermined period Ask as. The predetermined period is appropriately set, and is set to, for example, 6 hours, 24 hours, 1 week, or the like.

The storage processing unit 224 obtains the distance between the first and second positions received by the SV communication IF unit 21 from the fixed terminal apparatus SP via the network NW, and sets the obtained distance as a predetermined standardized value This information is stored in the standardization information storage unit 231a. Here, the SV communication IF unit 21 corresponds to an example of an acquisition unit that acquires the first and second positions. In the present embodiment, the SV communication IF unit 21 as an example of the acquisition unit acquires the first and second positions input from the fixed terminal apparatus SP via the network NW as described later.

Configured Hereinafter, an operation of position setting for setting the first and second positions will be described first, and then, an operation of measurement for obtaining an index value for self-support will be described.

(Position setting)
In the position setting, for example, when the terminal device SP, TA, for example, the fixed terminal device SP receives an input operation of position setting for specifying the monitored person Ob by its name and setting the first and second positions, the fixed terminal The device SP is a communication signal (position setting) that contains the name of the designated measured person (monitored person) Ob (or the sensor ID of the sensor device SU that monitors the monitored person Ob) and information for requesting position setting The request communication signal is transmitted to the management server device SVa. When the management server SVa receives the position setting request communication signal, the management server SVa acquires a target image from the sensor unit SU monitoring the subject Ob stored in the communication server, and stores the position setting screen using the target image. A communication signal (position setting screen notification communication signal) is sent back to the fixed terminal apparatus SP. The target image used for the position setting screen may be stored in advance in the management server device SVa. When the position setting screen notification communication signal is received, the fixed terminal device SP displays the position setting screen contained therein.

The position setting screen inputs positions as the first and second positions from the fixed terminal apparatus SP, and the first and second positions, and the distance between the first and second positions are the predetermined standardization. It is a screen for storing (registering) in advance in the SV storage unit 23a as a value and setting it in the management server device SVa. An example of this position setting screen is shown in FIG. The position setting screen 51 shown in FIG. 5 includes a “position” button 511 for inputting and setting positions as first and second positions, and a target image display area 512 for displaying the target image. In the example shown in FIG. 5, a plurality of “position” buttons 511 are configured in order to enable setting of a plurality of positions as the first and second positions. More specifically, the "position" button 511 is an "entry / exit" button 511-1 for inputting and setting each of the entry / exit EO, the washroom WR, the toilet facility LA, the bed BD, the chair, the window, the bookshelf and the chest. , "Wash-in" button 511-2, "indoor toilet" button 511-3, "bed" button 511-4, "chair" button 511-5, "window" button 511-6, "bookshelf" button 511-7 and It is configured to include a "tan" button 511-8. The “position” button 511 is, in one example, prepared for the input of the position represented by the “position” button 511 by the first input operation, and after the input of the position is received, the input is performed by the second input operation. The position is confirmed. In the present embodiment, the positions as the first and second positions are input in an area including the position, and are input in coordinate data representing the area. More specifically, when the “position” button 511 is input by the user for the first time, the cursor is displayed in the target image display area 512, and the four vertices of the area including the positions to be set as the first and second positions. Is input by the user using the cursor, and when the “position” button 511 is input by the user for the second time, coordinate data for the four vertices are stored as the position in the fixed terminal apparatus SP, “position The “” button 511 is displayed in a different display mode from when it has not been input. In the example shown in FIG. 5, the “outdoor” button 511-1, the “wash-in” button 511-2, and the “indoor toilet” button 511-3 are displayed in the display mode in which they have been input. , Coordinate data of 4 apexes of the entrance / exit area EOA including the position of the entrance / exit EO, coordinate data of 4 apexes of the washroom area WRA including the position of the wash water facility WR, and 4 of the toilet equipment area LAA including the position of the toilet equipment LA The coordinate data of the apex is stored, and the “bed” button 511-4 is input for the first time, and the four apexes of the bed area BDA including the position of the bed BD are designated by using the cursor, and the “chair” button 511- 5. The "window" button 511-6, the "bookshelf" button 511-7, and the "cloth" button 511-8 are displayed in an unentered display mode. Then, when all the “position” buttons 511 have been input, the fixed terminal device SP is a sensor of the sensor device SU that monitors the name of the designated subject (monitored person) Ob (or the monitored person Ob. And a communication signal (set position notification communication signal) in which each coordinate data of four vertexes representing each position in each area is associated with the position name of each position and transmitted to the management server SVa.

When the management server SVa receives this set position notification communication signal by the SV communication IF unit 21 via the network NW, the storage processing unit 224 of the SV control processing unit 22a first receives the received set position notification communication signal. Coordinate data of four vertexes representing each area of each of the positions accommodated in the received set position notification communication signal in association with the name (or sensor ID) of the accommodated measured person (monitored person) Ob And storing in the SV storage unit 23a in association with each position name of each position. Next, the management server device SVa causes the storage processing unit 224 to associate the name of the subject (monitored person) Ob contained in the received set position notification communication signal with the received set position notification communication signal. A standardized information table NT having each column 2311 and each row 2312 is generated with each position name of each position accommodated in the. Then, the management server device SVa uses the storage processing unit 224 to determine each distance between the first and second positions using each coordinate data of each position accommodated in the received set position notification communication signal, The distances between the first and second positions thus determined are registered as standardized values in the columns where the column 2311 and the row 2312 intersect. For example, the storage processing unit 224 obtains an intersection point of the diagonal line from the coordinate data of the four vertices as the coordinate value of the position, and based on the coordinate value of the first position and the coordinate value of the second position, Find the distance of For example, when obtaining the distance between the entrance / exit EO as the first position and the bed BD as the second position, the storage processing unit 224 determines the coordinates of the intersection of the diagonal lines from the coordinate data of the four vertices representing the entrance / exit area EOA of the entrance / exit EO. The value is obtained as the position of the entrance / exit EO, and the coordinate value of the diagonal intersection point is obtained as the position of the bed BD from each coordinate data of the four vertexes representing the bed area BDA of the bed BD. From the coordinate values of the position, the distance between the position of the entrance EO and the position of the bed BD is determined.

By such operation, each coordinate data of the four vertexes representing each area of each position is stored in the SV storage unit 23a, and the standardization information storage unit 231a is used as the first predetermined standardization value And the distance between the second position and the second position are stored and preset.

Further, by setting a plurality of positions such as an entrance and exit, a window, a washroom, and a toilet facility as the first and second positions, the subject Ob goes out, exchanges air in the room RM, washroom, and so on. It can be reflected in the index value of independence whether the actions are carried out independently and positively.

In addition, when the management server device SVa includes the SV input unit 24 and the SV output unit 25, the SV setting unit 24 and the SV output unit 25 may be used instead of the fixed terminal apparatus SP when such management operation of position setting is performed. It may be implemented by using. In addition, a user such as a care person measures each position of each room RM, manually creates a standardization information table NT based on the measurement result, and standardizes the created standardization information table NT as the management server apparatus SVa. You may memorize | store in the information storage part 231a.

(Measurement operation)
In the measurement operation, the sensor unit SU generates a target image by the imaging unit at predetermined time intervals (for example, every frame or every few frames), and generates the generated target image via the network NW. In response to this, the management server device SVa operates as follows to execute a predetermined operation for obtaining an index value of independence of the person to be measured (monitored person) Ob. doing.

In FIG. 6, first, the management server device SVa receives the image notification communication signal transmitted from the sensor device SU by the SV communication IF unit 21 by the movement distance processing unit 222a of the SV control processing unit 22a, thereby the target image To obtain (S11).

Next, the management server device SVa detects the position of a person based on the target image contained in the received image notification communication signal by the moving distance processing unit 222a, and is contained in the received image notification communication signal. The name is stored in the SV storage unit 23a in association with the name (or sensor ID) of the subject Ob (S12). More specifically, the movement distance processing unit 222a extracts an area different from the background as an area (person area) of the person of the person to be measured Ob from the target image by, for example, the background subtraction method, and circumscribed rectangle of the extracted person area (Or circumscribed circle) is determined, and the center position is determined as the position of the person. For example, when the target image is the image shown in FIG. 7A, the human region HA shown in FIG. 7B is extracted by the background subtraction method, its circumscribed rectangle CR is determined, and its center position HP is the position HP (Mxf, M) of the person. It is required as Myf).

Next, the management server device SVa determines, by the movement distance processing unit 222a, whether or not the position HP of the person obtained in the processing S12 is the position set as the first and second positions. In the present embodiment, as described above, the first and second positions are set in an area including the first and second positions. For this reason, more specifically, the moving distance processing unit 222a is associated with the name (or sensor ID) of the person to be measured Ob contained in the received image notification communication signal from the SV storage unit 23a. The coordinate data of the four vertexes representing each area of each position is taken out, and it is judged whether or not the position HP of the person found in the processing S12 is within each area of any of the taken out positions. To do (S13). As a result of this determination, if the position HP of the person obtained in the processing S12 is within each area of any of the above-mentioned respective positions (Yes), the management server device SVa performs the next operation by the movement distance processing unit 222a. Then, the process S21 is executed. On the other hand, if it is determined that the position HP of the person determined in step S12 is not within each area of any one of the positions (No) as a result of the determination, the management server device SVa determines Then, the process S31 is executed.

For example, if the target image received in step S11 is the image shown in FIG. 8A, then in step S12 the person area HA shown in FIG. 8B is extracted by background subtraction and its circumscribed rectangle CR is determined. The HP is obtained as the position HP of the person. Then, in the process S13, as shown in FIG. 8B and FIG. 8C, when the area WRA of the washroom facility WR is stored in advance in the SV storage unit 23a as the first and second positions shown in FIG. 8B. Since the position HP of the person found in the process S12 is within the area WRA of the wash water facility WR, the position HP of the person found in the process S12 as a result of the determination is one for each of the respective positions. The movement distance processing unit 222a determines that the region is within the area, and then executes the processing S21.

In the process S21, the management server device SVa determines, by the movement distance processing unit 222a, whether or not the SV storage unit 23a stores the first position. In the present embodiment, the movement distance information table MT shown in FIG. 4 is stored in the movement distance information storage unit 232a of the SV storage unit 23a. For this reason, more specifically, the movement distance processing unit 222a first corresponds to the name (or sensor ID) of the person to be measured Ob contained in the received image notification communication signal from the movement distance information storage unit 232a. Take out the attached movement distance information table MT. Next, the moving distance processing unit 222a removes the record in which the moving distance data is registered in the moving distance field 2324 from the extracted moving distance information table MT, and the nearest position data is registered in the position field 2321. Determine if there is a record added to. As a result of the determination, when such a record exists, it is determined that the first position is stored (Yes), and the movement distance processing unit 222a next executes a process S23. On the other hand, as a result of the determination, when such a record does not exist, it is determined that the first position is not stored (No), and the movement distance processing unit 222a performs processing after performing processing S22 next. Execute S23.

In the process S22, the management server device SVa causes the movement distance processing unit 222a to store the first position in the SV storage unit 23a. More specifically, in the present embodiment, the moving distance processing unit 222a first adds a new record to the moving distance information table MT extracted from the moving distance information storage unit 232a in step S21. Then, the movement distance processing unit 222a registers the position determined in step S13 as the first position in the position field 2321 of the newly added record, and registers the current time in the in time field 2322 of the added record. .

In the process S23, the management server device SVa determines whether or not the position (determination position) determined in the process S13 is different from the first position (whether or not it matches) by the movement distance processing unit 222a. More specifically, in the present embodiment, the moving distance processing unit 222a first sets the position name as the first position in the position field 2321 in the moving distance information table MT extracted from the moving distance information storage unit 232a in step S21. The data of the position name registered in the position field 2321 of the record added most recently is registered. Next, the movement distance processing unit 222a determines whether the determination position determined in the process S13 is different from the extracted position name (whether or not it matches). As a result of the determination, if the determination position is different from the position name (if it does not match (Yes)), the moving distance processing unit 222a sequentially executes each of the processes S24 to S27. The process S14 is executed. On the other hand, as a result of the determination, if the determination position does not differ from the position name (if it matches, No), the moving distance processing unit 222a next executes a process S14.

In the process S24, the management server device SVa obtains the divided movement distance by the movement distance processing unit 222a, and stores it in the SV storage unit 23a. More specifically, the moving distance processing unit 222a first determines the subject to be measured in the present processing S12 from the previous position (the position HP of the previous person) of the subject Ob determined in the previous processing S12. The distance to the current position of Ob (the position HP of the current person) is obtained as a divided movement distance. Then, the movement distance processing unit 222a stores the obtained divided movement distance in the SV storage unit 23a in association with the name (or sensor ID) of the subject Ob stored in the received image notification communication signal. .

In the process S25 executed after the process S24, the management server device SVa causes the movement distance processing unit 222a to store the second position in the SV storage unit 23a. More specifically, in the present embodiment, the moving distance processing unit 222a first adds a new record to the moving distance information table MT extracted from the moving distance information storage unit 232a in step S21. Then, the moving distance processing unit 222a registers the determination position determined in step S13 as the second position in the position field 2321 of the newly added record, and registers the current time in the in time field 2322 of the added record. Do.

In the processing S26 executed after the processing S25, the management server device SVa obtains the moving distance from the first position to the second position by the moving distance processing unit 222a, and stores the moving distance in the SV storage unit 23a. More specifically, in the present embodiment, the movement distance processing unit 222a first corresponds to the name (or sensor ID) of the subject Ob measured in the received image notification communication signal from the SV storage unit 23a. The divisional movement distances obtained by the execution of the process S24 or by the execution of the process S34 described later are taken out, and the sum of the taken out divisional movement distances is obtained as the movement distance. As a result, during the movement from the first position to the second position in the subject Ob, each divided movement distance obtained each time the position (current position) of the subject Ob is measured is from the first position to the second position. The position is accumulated (summed), and the movement distance of the subject Ob from the first position to the second position is obtained by measurement. Then, the movement distance processing unit 222a records the first position in the position field 2321 and the second position in the position field 2321 with respect to the movement distance information table MT extracted from the movement distance information storage unit 232a in processing S21. A new record is added to the record to be registered, and the calculated moving distance is registered in the moving distance field 2324 in the newly added record.

In the process S27 executed after the process S26, the management server SVa is the determination position determined in the process S13 by the movement distance processor 222a, and is registered (stored) in the movement distance information table MT in the process S25. The second position is updated (changed) to the first position. As a result, the second position is set as the first position as the start point of the next movement of the person to be measured Ob, and the movement distance of the next movement of the person to be measured Ob can be calculated.

On the other hand, in the process S31, the management server device SVa determines whether the SV storage unit 23a stores the first position or not by the moving distance processing unit 222a, as in the process S21. More specifically, the moving distance processing unit 222a first associates the moving distance information storage unit 232a with the name (or sensor ID) of the subject Ob stored in the received image notification communication signal. The movement distance information table MT is taken out. Next, the moving distance processing unit 222a removes the record in which the moving distance data is registered in the moving distance field 2324 from the extracted moving distance information table MT, and the nearest position data is registered in the position field 2321. Determine if there is a record added to. As a result of the determination, when such a record exists, it is determined that the first position is stored (Yes), and the movement distance processing unit 222a next executes a process S32. On the other hand, as a result of the determination, when such a record does not exist, it is determined that the first position is not stored (No), and the moving distance processing unit 222a ends the present process of this time.

In the process S32, the management server device SVa determines, by the movement distance processing unit 222a, whether or not the storage of the first position further includes the storage of the out time. More specifically, the moving distance processing unit 222a determines whether or not time data is registered in the out time field 2323 in the record searched in the processing S31. As a result of this determination, if time data is registered in the out time field 2323, it is determined that storage of the first position is stored (Yes), and the management server device SVa performs travel distance processing. Next, the process S34 is executed by the unit 222a. On the other hand, as a result of the determination, if the time data is not registered in the out time field 2323, it is determined that the storage of the first position does not have the storage of the out time (No), and the management server SVa moves Next, after the process S33 is performed by the distance processing unit 222a, the process S34 is performed.

In the process S33, the management server device SVa causes the movement distance processing unit 222a to further store the out time in the storage of the first position. More specifically, in the present embodiment, the movement distance processing unit 222a performs processing of position data as the first position in the position field 2321 in the movement distance information table MT extracted from the movement distance information storage unit 232a in step S31. The current time is registered in the out time field 2323 of the record added immediately before the registration.

In the process S34, the management server device SVa obtains the divided movement distance by the movement distance processing unit 222a, and stores it in the SV storage unit 23a. More specifically, the moving distance processing unit 222a first processes the current process S12 from the previous position of the subject Ob (previous person's position HP) obtained in the previous process S12, as in the process S24. The distance to the current position (the position HP of the current person) of the person to be measured Ob obtained in the above is obtained as a divided movement distance. Then, the movement distance processing unit 222a stores the obtained divided movement distance in the SV storage unit 23a in association with the name (or sensor ID) of the subject Ob stored in the received image notification communication signal. .

Then, in the process S14, the management server device SVa determines, by the movement distance processing unit 222a, whether the predetermined period has ended. As a result of the determination, if the predetermined period has ended (Yes), the management server device SVa executes the process S15 next by the moving distance processing unit 222a, and then ends the current process. Do. On the other hand, as a result of the determination, if the predetermined period has not ended (No), the management server device SVa ends the present process of this time.

In the process S15, the management server device SVa uses the independence indicator processing unit 223a to obtain an independence indicator value for the subject Ob and outputs the obtained independence indicator value to the outside. More specifically, the self-supporting index processing unit 223a determines the moving distance of the subject Ob determined by the moving distance processing unit 222a and the predetermined standardized value stored in the standardized information storage unit 231a. An index value of independence in the subject Ob is determined. In the present embodiment, the self-supporting index processing unit 223a sets one of the two points (the start point of the movement) to the first position every time the person to be measured Ob moves to two different points within a predetermined period. And the moving distance of the subject Ob determined with the other point of the two points (the end point of the movement) as the second position, as the predetermined standardized value stored in the standardized information storage unit 231a. By dividing by the distance between 1 and the second position, index values of independence in the subject Ob are determined, and the sum of the determined index values is determined as an index value of the final independence in the predetermined period. . Then, the independence index processing unit 223a transmits the determined final independence indicator value to the fixed terminal device SP via the network NW, and the fixed terminal device SP receives the final independence indicator value Then, it displays this. When the management server device SVa includes the SV output unit 25, the independence indicator processing unit 223 a may output the determined indicator value of the independence for the SV output unit 25.

The measurement operation will be further described in one specific example. When the person-to-be-monitored monitoring support system MSa is activated, the person to be monitored (person to be measured) Ob is located at another point in the room RM except for the position preset in the position setting. After moving to the bed BD, it shall move to the toilet equipment LA. In such a case, when the monitored person monitoring support system MSa is activated, the sensor unit SU generates a target image by the imaging unit at each predetermined time, and the generated target image is transmitted via the network NW. In response to this, the management server SVa transmits the above-described processes shown in FIG.

Here, the management server device SVa moves the sensor device SU until the monitored person (measured person) Ob moves from the other point in the room RM to the bed BD excluding the position set in advance in the position setting. Each time the SV communication IF unit 21 receives the image notification communication signal sent from the device, it executes each processing of processing S11, processing S12, processing S13 (No) and processing S31 (No), and ends each measurement operation Do. By this operation, after activation, the moving distance of the subject Ob is not calculated and is not stored until the subject Ob reaches the position preset in the position setting.

When the subject Ob moves to the bed BD and the management server device SVa receives the image notification communication signal transmitted from the sensor device SU by the SV communication IF unit 21, processing S11, processing S12, processing S13 (Yes), Each process of process S21 (No), process S22, process S23, and process S14 (No) is performed, and this measurement operation is complete | finished. By this operation, when the subject Ob reaches a position preset in position setting after being activated, the position is stored as a first position.

While the subject Ob is moving in the bed area BDA including the position of the bed BD, the management server device SVa receives the image notification communication signal transmitted from the sensor device SU by the SV communication IF unit 21. The process S11, the process S12, the process S13 (Yes), the process S21 (Yes), the process S23 (No) and the process S14 (No) are executed, and the measurement operation of each time is ended. While the subject Ob moves in the bed area BDA by this operation, the moving distance of the subject Ob is not calculated and is not stored.

When the measured person Ob leaves the bed area BDA and the management server SVa receives the image notification communication signal transmitted from the sensor SU at the SV communication IF unit 21, the process S11, the process S12, the process S13 (No Each process of process S31 (Yes), process S32 (No), process S33, process S34 and process S14 (No) is performed, and the current measurement operation is ended. By this operation, the out time of the first position is stored, and the first segment movement distance is obtained and stored.

During the period from the bed BD to the toilet equipment LA, the management server device SVa receives the image notification communication signal transmitted from the sensor device SU by the SV communication IF unit 21, and the process S11 and the process S12 are performed. The process S13 (No), the process S31 (No), the process S32 (No), the process S34 and the process S14 (No) are executed, and the measurement operation of each time is ended. By this operation, the divided movement distance of each time is obtained and stored.

Then, when the subject Ob reaches the toilet equipment LA (enters the toilet equipment area LAA including the position of the toilet equipment LA) and the image communication communication signal transmitted from the sensor device SU is received by the SV communication IF unit 21 Step S11, Step S12, Step S13 (Yes), Step S21 (Yes), Step S23 (Yes), Step S24, Step S25, Step S26, Step S27, and Step S14 (No). End the measurement operation of. By this operation, the movement distance when the subject Ob moves from the bed BD (first position) to the toilet equipment LA (second position) is determined and stored. Then, the toilet equipment LA, which is the end point of the current movement, is updated (changed) from the second position to the first position, and becomes the start point of the next movement.

Thereafter, when the subject Ob moves from the toilet facility LA to the washroom facility WR and further from the washroom facility to the bed BD, the management server device SVa operates in the same manner as described above. Thus, for example, a moving distance information table MT in which data of each moving distance is registered in the moving distance field 2324 shown in FIG. 4 is generated and stored in the moving distance information storage unit 232a. Then, when the predetermined period has passed and the management server device SVa receives the image notification communication signal transmitted from the sensor device SU by the SV communication IF unit 21, the processing S 11 to the processing S 14 at that time Each process according to the condition of the subject Ob is executed, and it is determined in the process S14 that the predetermined period has ended, and the process S15 is executed.

In this process S15, in the example shown in FIG. 4, the moving distance from the bed BD to the toilet facility LA is 4.0 m, the moving distance from the toilet facility LA to the washroom facility WR is 1.0 m, and the wash facility WR The moving distance from the bed to BD is 4.8 m, and in the example shown in FIG. 3, the standardized value between the bed BD and the toilet facility LA is 3.6 m, and the standardization between the toilet facility LA and the toilet facility WR is standardized. Since the value is 0.8 m and the standardized value between the toilet WR and the bed BD is 2.4 m, the index value of the independence between the bed BD and the toilet LA is 4.0 / 3.6 , The index value of independence between the toilet equipment LA and the toilet facility WR is 1.0 / 0.8, and the index value of independence between the toilet equipment WR and the bed BD is 4.8 / 2.4, But The index value of independence (final index of independence) in the predetermined period is (4.0 / 3.6) + (1.0 / 0.8) + (4.8 / 2.4). ) = 4.36 (rounded off to three decimal places).

If the room RM is relatively large, for example, the distance between the entrance and the bed and the distance between the window and the bed may be relatively long. On the other hand, if the room RM is relatively narrow, the distance between the entrance and the bed and the distance between the window and the bed become relatively short. In the self-supporting index measuring device and the self-supporting index measuring method, since the predetermined standardized value is the distance between the first and second positions, the index value reflecting the size of the room RM can be obtained.

In this case, the index value of the independence of the subject Ob is determined by multiplying the average segment moving distance by the average distance weight at each of the second time intervals to determine the average weighted segment moving distance, and the subject Ob While moving from the first position to the second position by calculating the sum of the average weighted segment moving distances obtained for each of the second time intervals. For example, when the segment movement distance and the corresponding distance weight are obtained every one minute, for example, the average segment movement distance and the corresponding average distance weight are obtained every five minutes. Then, for example, in the case where the subject Ob moves from the first position to the second position in 15 minutes, the first and third average weighted segment moving distances obtained every 5 minutes are calculated to obtain the first and the second.

It may be the distance from the specified specific position to the position of the subject Ob when the movement distance of the subject Ob is measured (timing). In this case, the movement distance measurement unit 222c measures the position of the measurement subject Ob at predetermined time intervals, and measures the position of the measurement subject Ob each time the measurement subject Ob measured in the previous time. The divisional movement distance from the previous position to the current position of the subject Ob measured this time is obtained. The self-supporting index processing unit 223c measures the distance from the specific position to the current position of the subject Ob measured at this time every time the position of the subject Ob is measured by the movement distance measuring section 222c. The second weighted classification moving distance is obtained by obtaining the predetermined weight (second distance weight) and multiplying the divided moving distance obtained by the moving distance measuring unit 222c by the second distance weight obtained correspondingly. An index value for independence of the subject Ob is obtained by obtaining the sum of the second weighted segment moving distances obtained each time the position of the subject Ob is measured by the moving distance measuring unit 222c. .

In the processing S15 in the modified embodiment of the third embodiment, each second weighted classification movement distance based on each classification movement distance and each second distance weight determined each time the position of the subject Ob is measured. The sum of the above is obtained as an index value of the independence of the subject Ob. Preferably, the specific position is a position (for example, bedding etc.) of the living base of the subject in the room.

Further, in the first to third embodiments described above, the divisional movement distance is synonymous with the movement speed by setting the predetermined time interval as a unit time for obtaining the speed.
