Description

The present disclosure relates to a record support system.

In recent years, information and communication technology (ICT) at nursing care sites has been attracting attention.

For example, by using a smartphone to record the contents of daily long-term care services (in other words, the contents of long-term care provided) and aggregating the recorded data on a personal computer (PC), document creation and document management related to long-term care records Attempts have been made to reduce the burden on the computer.

"One day with smart care" Regular patrol "", [online], [Search on July 17, 1st year of Reiwa], Internet <URL: http://www.smacare.jp/smacare/oneday-regularpatrol/>

In the existing technology as described above, authentication is performed by reading the user tag installed in the user's home of the long-term care service with a smartphone carried by the long-term care staff (or helper). Upon successful authentication, the start time of the long-term care service is recorded on the smartphone.

However, it is inconvenient for the long-term care staff who visits the user's home to read the user tag with a smartphone and perform authentication, and it is not always the case that a problem such as forgetting the authentication or failure of the authentication occurs.

Further, the contents of the long-term care service provided by the long-term care staff are recorded on the smartphone by manual input (including selection operation by touch operation) to the smartphone by the long-term care staff. However, since it is manually input, the input work burden on the care staff cannot be reduced.

In addition, for example, when there are detailed procedures, arrangements, rules, etc. regarding data entry work for smartphones, the care staff must accurately grasp all such procedures and always be appropriate at the actual care site. It is not always possible to enter data.

Therefore, erroneous recording may occur, and it takes time to identify and correct the erroneous recording, which may increase the work load. In addition, when the reliability of the long-term care record is lowered due to an erroneous record, it may lead to a decrease in the sense of trust and security for the long-term care service.

One of the purposes of the present disclosure is, for example, to reduce the recording burden.

The recording support system according to one aspect of the present disclosure is a transmitter that is installed in an area where a target is located and periodically emits radio waves, and a receiver that can move inside and outside the area, and receives the radio waves. Received intensity information recorded for each unit time of a receiver that records intensity information for each unit time and different degrees of involvement for the target, which are classified according to the distance from the transmitter. It is provided with an information processing device for determining based on.

According to one aspect of the present disclosure, for example, the recording burden of the long-term care record can be reduced.

The long-term care record support system 1 shown in FIG. 1 includes, for example, a transmitter 10, a receiver 30, and an information processing device 70. The transmitter 10 and the receiver 30 are both examples of radios. The "radio" may be referred to as a "radio device" or a "radio station".

The transmitter 10 and the receiver 30 do not require a license or registration such as WiFi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or BLE (Bluetooth low energy) as a non-limiting example. A radio station conforming to a low power wireless communication standard may be applied.

In the present embodiment, the transmitter 10 is, for example, a fixed station fixedly installed in a specific place or an object, and the receiver 30 is, for example, a mobile station that can be carried by a person. The transmitter 10 and the receiver 30 have a width (W) of several tens of millimeters (mm), a height (H) of several tens of mm, a thickness (D) of several tens of mm, and a weight, respectively, as non-limiting examples.

[Operation example]
Next, an operation example of the first embodiment will be described with reference to FIGS. 5 and 6. In the following description, a PC will be taken as an example of the information processing device 70.

In the upper part of FIG. 5, as an example, a transmitter (fixed station) 10 is installed in each room of # 1 house, # 2 house, and # 3 house, and a caregiver carrying a receiver (mobile station) 30 is carried. An example in which a staff member visits # 1, # 2, and # 3 homes to provide long-term care services is schematically shown.

For example, when the care staff visits the rooms in which the fixed stations 10 are installed in the order of # 1, # 2, and # 3, the mobile station (receiver) 30 receives the signals periodically. The reception strength information of the beacon signal is sequentially recorded in the memory 333.

By analyzing the reception intensity information recorded in the memory 333 of the mobile station 30 on the PC70, for example, the care staff for each of the # 1 home, the # 2 home, and the # 3 home, as illustrated in the lower part of FIG. The entry time and exit time of the room can be specified (or judged, estimated or detected).

It is also possible to specify the staying time of the care staff at each of the # 1, # 2, and # 3 homes from the entry time and the exit time. It can also be identified that the care staff visited the # 1 home, the # 2 home, and the # 3 home in that order (in other words, the movement route of the care staff).

In FIG. 5, as a non-limiting example, the care staff enters the # 1 home (IN) at 9:00 and leaves the # 1 home (OUT) at 10:20 (stay time = 1 hour). 20 minutes) is shown. Similarly, in FIG. 5, it is exemplified that the entry (IN) time to the # 2 house is 11:00 and the exit (OUT) time from the # 2 house is 11:55 (stay time = 55 minutes). It is exemplified that the entry (IN) time to the # 3 house is 14:00 and the exit (OUT) time from the # 3 house is 15:30 (stay time = 1 hour and 30 minutes).

In addition, the route of movement associated with the home-visit care of the long-term care staff may be estimated based on the specified order of visits. The estimated travel route may be shown on a map including # 1 home, # 2 home, and # 3 home, for example, as schematically shown in the lower left of FIG.

Further, the estimated time step size (in other words, the particle size) depends on, for example, the cycle of the reception intensity information recorded in the mobile station 30. For example, the shorter the transmission cycle of the beacon signal by the fixed station 10 (hereinafter, may be referred to as “beacon cycle”), the shorter the recording cycle of the reception intensity information, so that the particle size of the estimated time becomes shorter. In other words, the accuracy of time estimation (or determination) is improved.

On the other hand, the shorter the beacon cycle of the fixed station 10, the higher the power consumption of the fixed station 10. As described above, the beacon cycle and the power consumption of the fixed station 10 are in a trade-off relationship with each other. The beacon cycle may be set to an appropriate cycle according to the balance between the required accuracy of information and the power consumption of the fixed station 10.

As a non-limiting example, when the beacon cycle is 1 second, the fixed station 10 can be used continuously for a period of several years (for example, 6 years) without battery replacement or recharging. When the beacon cycle is set to 2 seconds, the continuous usable period of the fixed station 10 can be extended to about 1.5 to 2.0 times, for example, as compared with the case where the beacon cycle is 1 second.

Although FIG. 5 shows an example in which the same care staff visits the # 1 home, the # 2 home, and the # 3 home in order, they visit the # 1 home, the # 2 home, and the # 3 home. The care staff may be different care staff for # 1 home, # 2 home, and part or all of # 3 home. Further, the # 1 house, the # 2 house, and the # 3 house may be read as, for example, different rooms # 1, room # 2, and room # 3 in the same building or facility. These points are the same in the following description.

Next, with reference to FIG. 6, recording of reception intensity information (for example, RSSI) by the mobile station 30 will be described.

In FIG. 6A, fixed stations 10 # 1, 10 # 2 and 10 # 3 installed in each room of the # 1 house, the # 2 house, and the # 3 house send a beacon signal in a predetermined cycle (for example,). An example of transmitting at a cycle of 1 second is shown. Note that # 1 to # 3 may be regarded as representing the identification information (in other words, the source ID) of the fixed stations 10 installed in the # 1 home, the # 2 home, and the # 3 home, respectively. The beacon signal may include the ID.

For example, the fixed station 10 installed in the # 1 home periodically transmits a beacon signal including ID = # 1. Similarly, the fixed station 10 installed in the # 2 home periodically transmits a beacon signal containing ID = # 2, and the fixed station 10 installed in the # 3 home periodically transmits a beacon signal containing ID = # 3. Is transmitted periodically.

FIG. 6B shows that the mobile station 30 carried by the care staff is in a state of waiting for continuous reception of radio waves (for example, a beacon signal) after the power is turned on.

FIG. 6C shows the change in RSSI distance measured by the mobile station 30 in the continuous reception standby state. The distance change represents, for example, a change in RSSI according to the distance from the fixed station 10 which is the source of the beacon signal.

As an example, FIG. 6C shows an example in which the mobile station 30 carried by the care staff increases RSSI as it approaches the fixed station 10, and decreases RSSI as it moves away from the fixed station 10.

FIG. 6D shows an example in which RSSI is recorded every unit time (for example, 1 second) in the mobile station 30. The RSSI recording destination in the mobile station 30 may be, for example, the memory 333 as described above.

As illustrated in FIG. 6D, the mobile station 30 uses the RSSI of the received beacon signal and the source ID (hereinafter, may be abbreviated as “beacon ID”) included in the beacon signal. Record in chronological order for each unit time.

For example, in FIG. 6D, t1, t2, ..., T21, ... Represent the time (timing) for each unit time, and RSSI1, RSSI2, ..., RSSI21, ... Represents the RSSI recorded at times t1, t2, ..., T21, ..., Respectively, respectively.

The time (or timing) t1, t2, ..., T21 may be an absolute time or may be represented by a relative time from a certain time. By way of example, the “certain time” may be the time when RSSI recording is started in the mobile station 30, or the time when the recording (data) in the mobile station 30 is taken into the PC 70.

In the example of FIG. 6D, RSSI1 to RSSI5 of the beacon signal (beacon ID = # 1) transmitted by the fixed station 10 # 1 are recorded in the mobile station 30 during the period of time t1 to t5. Further, during the period from time t8 to t12, RSSI8 to RSSI12 of the beacon signal (beacon ID = # 2) transmitted by the fixed station 10 # 2 are recorded in the mobile station 30. Further, during the period from time t17 to t21, RSSI17 to RSSI21 of the beacon signal (beacon ID = # 3) transmitted by the fixed station # 3 are recorded in the mobile station 30.

Note that a part or all of FIGS. 6 (a) to 6 (d) may be regarded as an example of display (or printing) by the output device (for example, display) 706 of the PC 70, for example.

The RSSI data (hereinafter sometimes referred to as “RSSI data”) recorded in the mobile station 30 (for example, the memory 333) may be provided to the PC 70 at an appropriate timing. By analyzing RSSI data, for example, the PC 70 can generate and output (for example, screen display or print) information such as the visit destination, visit time, and stay time at the visit destination of the care staff.

The RSSI recording cycle (or recording frequency) by the mobile station 30 may be set based on, for example, the memory capacity of the mobile station 30 and / or the battery consumption. For example, when it is desired to record a long-time action, the recording cycle is set to a unit longer than 1 second, for example, a unit of 10 seconds or more, and the maximum value of RSSI in one cycle is recorded in the mobile station 30. .. By setting the recording cycle to a cycle longer than 1 second in this way, for example, it is possible to suppress variations in recording due to instantaneous fluctuations in beacon radio waves.

Further, when the recording cycle is set to a cycle longer than 1 second, for example, 10 seconds, the battery consumption can be saved by turning on / off the beacon reception operation of the mobile station 30 in units of 2 seconds, for example (for example, the mobile station). The operating time of 30 can be doubled). In this case, the mobile station 30 may acquire the RSSI of 5 values every 2 seconds in 10 seconds and record the maximum value of the 5 values in the memory 333.

As described above, according to the first embodiment, the behavior associated with the care by the care staff (for example, a visit to a visited place) can be recorded electronically and automatically. Therefore, it is possible to reduce the forgetting of the visit record and the recording error by the care staff, and it is possible to reduce the burden of the recording work.

In addition, since accurate records can be obtained, for example, the person in charge of supervision of the long-term care service can check the appropriateness of the behavior associated with long-term care, such as whether or not the long-term care staff actually visited and stayed at the care-requiring person's house as scheduled. Can be confirmed and verified. Further, since it is an electronic record, it is easy to share information among, for example, a person requiring long-term care, a long-term care staff, and a supervisor (hereinafter, may be collectively referred to as a “long-term care service related person”).

Therefore, for example, the discrepancy in the talk about the visit between the care staff and the care recipient can be verified based on the accurate record, the mental burden on the care staff can be reduced, and the relationship of trust between the care staff can be built. And / or contribute to improving the sense of security for long-term care services.

Further, for example, since it is not necessary to monitor the care recipient's home or the care staff using a surveillance camera, the privacy of the care recipient and the care staff can be protected.

<Embodiment 2>
Next, the second embodiment will be described. In the second embodiment, based on the RSSI data recorded in the mobile station 30, in addition to information such as the visit destination, visit time, and stay time of the care staff, the content of the care service at the visit destination is specified (determined, An example of estimating or detecting) will be described.

FIG. 7 is a schematic diagram showing an example of the relationship between the reception intensity information in the mobile station 30 and the area division with respect to the distance between the individual fixed stations 10 and the mobile station 30.

As illustrated with reference numeral 91 in FIG. 7, the received radio field intensity measured by the mobile station 30 is attenuated in inverse proportion to the square of the distance between the mobile station 30 and the fixed station 10 in free space. To do. In this attenuation curve (also referred to as “theoretical curve”) 91, the position where the received radio wave intensity is not measured corresponds to the limit (boundary) of the communication area of the fixed station 10.

On the other hand, focusing on the attenuation curve 91 inside the boundary of the communication area, it can be understood that the degree of attenuation differs depending on the proximity of the mobile station 30 to the fixed station 10. Focusing on this point, the communication area of the fixed station 10 can be divided into a plurality of concentric areas (or zones) centered on the fixed station 10, for example.

As a non-limiting example, FIG. 7 shows an example in which the communication area of the fixed station 10 (in other words, the area where the long-term care recipient is located) is divided into three areas A to C. Area C is, for example, an area where the proximity of the mobile station 30 to the fixed station 10 is lower than that of the other division areas A and B. Area C is associated with, for example, a case where the mobile station 30 is located in the site of the building, not in the building (indoor).

Area A is, for example, an area where the proximity of the mobile station 30 to the fixed station 10 is higher than that of other areas. Area A is associated with, for example, a case in which the mobile station 30 is close to the care recipient in the building (indoor).

Area B corresponds to, for example, an intermediate area between area A and area C, and is associated with a case where the mobile station 30 is located in a building. In FIG. 6, the area D indicates an area outside the communication area of the fixed station 10 (hereinafter, may be referred to as “out-of-service area D”).

Further, in the area division (or area setting) according to the proximity of the mobile station 30 to the fixed station 10, for example, the contents of the care service provided by the care staff may be associated with the individual areas A to C. ..

As a non-limiting example, areas A to C have "direct (physical care)", "visit (life support)" and "stop-in (safety confirmation)", respectively, as illustrated in Table 1 below. May be associated. The information or data exemplified in Table 1 (hereinafter, may be referred to as "division area vs. long-term care service table" for convenience) may be stored in, for example, the storage 703 or the memory 702 of the PC 70.

A non-limiting example of "direct" (physical care) is work that involves physical contact with the care recipient, such as cleaning / conditioning, excretion assistance, mobility assistance, and meal assistance. Be done.

A non-limiting example of "visit" (life support) is to some extent for care recipients in a room or a separate room where a fixed station 10 is installed, such as cleaning, cooking, laundry, medication confirmation, and clothing arrangement. Work in a state where the distance is maintained (in other words, work that does not involve physical contact with the care recipient) can be mentioned.

“Stop-by” (safety confirmation) is, for example, a work in which a long-term care staff visits the site of a building where a long-term care recipient lives to confirm the safety of the long-term care recipient.

As described above, by associating the contents of the long-term care service with each of the areas A to C classified according to the change in the distance of the RSSI, the long-term care staff in the PC70, for example, based on the RSSI data recorded in the mobile station 30. Can identify the content of the long-term care service provided by the visitor. In other words, the degree of relationship between the care staff and the person requiring long-term care (may be referred to as "degree of involvement" or "degree of care") can be specified based on the RSSI data.

The time when the change (increase) in RSSI indicates the entry into the division area C corresponds to the time when the care staff enters the home of the person requiring long-term care, and the change (decrease) in RSSI is from the division area C. The time when the withdrawal is indicated may be regarded as corresponding to the time of departure from the care recipient's home.

In other words, in the above-described first embodiment, the information on when the care staff visits the visited place and when the care staff leaves the visited place can be regarded as one aspect of the information on the degree of involvement with the care recipient.

In addition, the out-of-service area D may be associated with information indicating that the care staff has not visited the care-requiring person's home, or something different from the work related to the care service such as "moving". Work may be associated.

The determination as to whether the mobile station 30 belongs to the division areas A to C or the out-of-service area D (hereinafter, may be referred to as "area determination" or "zone determination") is exemplarily performed by the threshold value determination of RSSI. You can.

Here, as illustrated with reference numeral 92 in FIG. 7, the actual RSSI measured by the mobile station 30 (hereinafter, may be referred to as “RSSI measured value”) is due to peripheral reflection, the influence of the human body, or the like. , The positional relationship between the fixed station 10 and the mobile station 30 and the time may vary.

Therefore, in the present embodiment, for example, the maximum value of RSSI that does not reach unless the division area is entered may be used for the "area determination". In other words, the mobile station 30 may record the maximum value of RSSI for each unit time. In addition, in FIG. 7, the theoretical curve 91 may be regarded as corresponding to a locus traced by the maximum value of the RSSI measured value corresponding to the distance indicated by reference numeral 92.

As illustrated in FIG. 7, three threshold values Th1, Th2 and Th3 (Th1> Th2> Th3) for RSSI may be used for the area determination of the division areas A to C and the out-of-service area D.

FIG. 8 is a flowchart showing an example of area determination using the threshold values Th1, Th2 and Th3. As illustrated in FIG. 8, the PC 70 receives input of RSSI data from, for example, the mobile station 30 (S11).

Then, the PC 70 compares, for example, the RSSI data with the threshold values Th1, Th2 and Th3 (S12, S13, S14). When the result of the comparison is RSSI ≧ Th1 (Yes in S12), the PC70 may determine that the care staff (the mobile station 30 carried by the mobile station 30) is located in the area A (S15). Alternatively, the PC 70 may determine that the care staff (carrying mobile station 30) is not located at least in any of areas B, C, and D.

When the result of the comparison is Th2≤RSSI <Th1 (No in S12 and Yes in S13), the PC70 may determine that the care staff (carrying mobile station 30) is located in the area B (S16). Alternatively, the PC 70 may determine that the care staff (carrying mobile station 30) is not located at least in any of areas C and D.

Similarly, when the result of the comparison is Th3≤RSSI <Th2 (No in S13 and Yes in S14), the PC70 may determine that the care staff (the mobile station 30 carried by the mobile station 30) is located in area C (the mobile station 30 carried by the care staff) S17). Alternatively, the PC 70 may determine that the care staff (carrying mobile station 30) is not located at least in the out-of-service area D.

Further, when the result of the comparison is RSSI <Th3 (No in S14), the PC 70 may determine that the care staff (the mobile station 30 carried by the mobile station 30) is located in the out-of-service area D (S18). Alternatively, the PC 70 may determine that the care staff (carrying mobile station 30) is not located at least in any of areas A, B, and C.

When any of the determination results shown in S15 to S18 is obtained, the PC 70 confirms, for example, whether or not unprocessed RSSI data exists (S19). If there is unprocessed RSSI data (Yes in S19), the PC 70 returns the processing to S12. If there is no unprocessed RSSI data (No in S19), the PC 70 may terminate the process.

Since the ranges of area B and area C may differ depending on the building structure of the visited destination where the fixed station 10 is installed, the threshold values Th1, Th2 and Th3 in actual operation are set according to the usage environment (for example, visit). It may be set individually (for each home).

Further, the PC 70 may, for example, create a table of the determination conditions and the determination results shown in the flowchart of FIG. 8 and perform the above-mentioned area determination by pulling the table. The table may be stored in, for example, the storage 703 or the memory 702 shown in FIG.

FIG. 9 schematically shows an operation example of the second embodiment as a comparative example of FIG.
In the upper part of FIG. 9, as in FIG. 5, a transmitter (fixed station) 10 is installed in each room of # 1 house, # 2 house, and # 3 house as an example, and a receiver (mobile station) is installed. ) A case in which a long-term care staff carrying 30 visits # 1 home, # 2 home, and # 3 home to provide long-term care services is schematically shown.

In the middle of FIG. 9, for example, an example in which the division areas A to C shown in FIG. 7 are formed by the fixed stations 10 installed in the # 1 home, the # 2 home, and the # 3 home, respectively, is schematically an example. Shown in.

In the lower part of FIG. 9, the care staff visits the # 1 house at 9:00, and between 9:00 and 10:20, according to the passage of time, the division area C (stop-by) and the division area B ( An example of positioning (moving) in the order of (visit) and division area C is shown. In this case, it is specified that the long-term care staff provided life support (cleaning, cooking, laundry, medication confirmation, clothing arrangement, etc.) to the long-term care recipient while being located in the division area B.

Further, in the # 2 house, an example is shown in which the care staff visits at 11:00 and is located in the division area C (stop-in) between 11:00 and 11:55. In this case, it is specified that the long-term care staff, for example, confirms the safety of the person requiring long-term care while being located in the division area C.

In addition, the care staff visits the # 3 house at 14:00, and between 14:00 and 15:55, according to the passage of time, the division area C (stop-by), the division area B (visit), and the division. An example of positioning (moving) in the order of area A (directly), division area B, and division area C is shown.

In this case, the long-term care staff provides life support to the care-requiring person (see Table 1) while being located in the division area B, and for example, physical care of the care-requiring person while being located in the division area C (see Table 1). It is specified that (see Table 1) was performed.

The care staff who visits # 1 home, # 2 home, and # 3 home may be the same care staff for all of # 1 home, # 2 home, and # 3 home, or # 1 home, # 3 home. The care staff may be different for 2 homes and part or all of # 3 homes.

As described above, according to the second embodiment, based on the RSSI data recorded in the mobile station 30 carried by the long-term care staff, for example, in the PC 70, the degree of relationship between the long-term care staff and the care-requiring person according to the division area. Can be identified.

Therefore, in addition to obtaining the same action and effect as in the first embodiment, the following action and effect can be obtained.

-Since the long-term care staff does not have to individually record the degree of involvement with the person requiring long-term care (for example, the content of the long-term care service) at the visited place, the burden of recording work can be reduced.

-Since accurate records can be obtained, for example, the supervisor of the long-term care service can confirm and verify the appropriateness of the long-term care service content, such as what kind of long-term care service the long-term care staff provided at the visited place.

-Since it is an electronic record, it is easy to share information among people involved in nursing care services, for example.

-Therefore, for example, it contributes to the verification of troubles such as neglect, neglect, and "theft delusion" of the care-requiring staff, appropriate response to the trouble, and prevention of the trouble.

・ For example, the discrepancy in the talk about care between the care staff and the care recipient can be verified based on accurate records, reducing the mental burden on the care staff, building a relationship of trust between the care staff, and / Or contribute to improving the quality of long-term care services and the sense of security.

-In addition, for example, since it is not necessary to monitor the long-term care recipient or the long-term care staff using a surveillance camera, the privacy of the long-term care recipient and the long-term care staff can be protected.

<Embodiment 3>
Next, the third embodiment will be described with reference to FIGS. 10 and 11. 10 and 11 are diagrams schematically showing a mode in which the communication areas of the plurality of fixed stations 10 overlap each other.

As illustrated in FIG. 10, since a plurality of buildings in which the fixed stations 10 are installed are close to each other, the communication areas of the fixed stations 10 may partially overlap each other. Further, as illustrated in FIG. 11, the communication areas of the fixed stations 10 installed in a plurality of rooms in the same building (for example, a long-term care facility) may partially overlap each other.

In this way, when the communication areas of the plurality of fixed stations 10 partially overlap each other, the mobile station 30 sets the larger value (for example, the maximum value) of RSSI for each unit time (for example, 1 minute). By recording, the communication area can be selected.

For example, the mobile station 30 receives beacon signals from a plurality of fixed stations 10 in an area where the communication areas of different fixed stations 10 overlap, but the larger of the RSSIs of the received beacon signals. The value (for example, the maximum value) is recorded in the memory 333.

By such maximum value recording, for example, information (or data) such as the visit destination of the care staff and the time of entry / exit to the visit destination can be recorded and managed as in the first embodiment, and the same as in the second embodiment. Area judgment can also be made.

<Example of using long-term care record information>
Next, an example of utilizing RSSI data recorded in the mobile station 30 will be described with reference to FIGS. 12 to 15. The utilization example may be applied to any of the above-described first and second embodiments. The figures illustrated in FIGS. 12 to 15 may be regarded as an example of a display screen (or printing) by the output device (for example, display) 706 of the PC 70, for example.

FIG. 12 shows an example of entry / exit records and area determination results based on RSSI data for each of a plurality of care staff (caregivers) and / or a plurality of users (care recipients) in a care facility in chronological order. It is a figure.

For example, in the upper part of FIG. 12, the rooms of the visited destinations (any of users # 1 to # 3) are shown in chronological order separately from the care staff # A to # C. For example, staff # A visits user # 1's room between 1 am and 3 pm, and user # 3 visits user # 3 between 4 am and 6 am. It is shown that he visited the room and visited the room of user # 2 between 6:00 and 7:00 in the early morning. The same applies to staff # B and staff # C.

On the other hand, in the lower part of FIG. 12, the staff members (# A to # C) who visited each room are shown in chronological order according to the users # 1 to # 3. In addition, in FIG. 12, the degree of care according to the area determination result may be displayed (in other words, highlighted) by color coding, for example.

The distinction between users # 1 to # 3 may be made based on, for example, the ID of the fixed station 10 in the RSSI data. Further, the long-term care staff may be distinguished based on, for example, the ID of the mobile station 30, and when the PC 70 captures the RSSI data from the mobile station 30, the long-term care staff identification information is added to the RSSI data. It may be done in.

Next, in FIG. 13, the room number visited by a certain care staff (or staff) and the entry / exit time are shown in chronological order. The display mode of FIG. 13 may be selectively or in parallel for each care staff on the display 706 of the PC 70, for example.

Next, in FIG. 14, for each room (room number) of the care recipient, who of the care staff (or staff) identified by the numbers “01” to “24” visits and stays from what time to what time. It is shown in chronological order. Further, for each staying time of the care staff, for example, the RSSI may be indicated by color coding, or the care level corresponding to the above-mentioned area determination result based on the RSSI may be indicated by color coding.

In addition, in FIG. 14, it is shown that the hatched time zone is displayed in different colors. In FIG. 14, the hatching indicating the color coding is partially attached, but the hatching may be totally color-coded according to the RSSI or the area determination result.

Next, FIG. 15 shows RSSI data (or the above-mentioned area determination result based on RSSI data) for each room (room number) for a specific care staff (or staff) in chronological order. .. The RSSI data may be color-coded in a plurality of stages according to the strength. In addition, in FIG. 15, it is shown that the portions with different types of hatching are colored differently depending on the strength of RSSI.

Information among care service personnel is obtained by displaying a part or all of the display modes illustrated in FIGS. 12 to 15 on the display 706 selectively, in parallel, or in an integrated manner, for example, on the PC 70. Easy to share. Therefore, for example, it becomes easy for the long-term care staff to verify the appropriateness of the long-term care service, and it contributes to the improvement of the quality of the long-term care service and the sense of security such as the appropriateness of troubleshooting and the prevention of troubles.

It should be noted that the presentation of the information by visualization as illustrated in FIGS. 12 to 15 may be performed by another aspect different from the above-mentioned example.

Further, for example, artificial intelligence (AI) may be used for processing such as area determination in the PC 70 and association of the care level (or care service content) according to the area determination result.

Further, in each of the above-described embodiments, an example in which the transmitter 10 is installed in an area (for example, a building or a room) where the care recipient is at home (position) and the receiver 30 is carried by the caregiver has been described. , The relationship between the two stations may be reversed. For example, the receiver 30 may be installed in an area where the care recipient is located (for example, a building or a room), and the transmitter 10 may be carried by the caregiver. In that case, for example, the RSSI data recorded by the receiver 30 in the home area of the person requiring long-term care may be transmitted to the information processing device 70 via a communication line such as a local area network (LAN) or the Internet.

Further, in each of the above-described embodiments, the example in which the transmitter 10 is a fixed station has been described. However, for example, the transmitter 10 may be installed in an area or an object whose position can be changed and may be movable. Good. For example, the transmitter 10 may be installed on a mobile body used by the care recipient, such as a wheelchair or a variable bed, or may be carried by the care recipient.

<Application examples in other fields>
The above-mentioned long-term care record support system 1 may be applied not only to the long-term care field but also to other fields.

For example, the system 1 described above may be applied to record work related to replenishment or replacement of goods in a vending machine. For example, the fixed station 10 is installed inside the vending machine, and the worker carries the mobile station 30. When the worker opens the door of the vending machine, the intensity of the radio wave received by the mobile station 30 of the beacon signal from the fixed station 10 rapidly increases (for example, it corresponds to the above-mentioned division area A). Therefore, it is possible to record when and when the worker performed work such as replenishment or replacement for which vending machine.

Further, the above-mentioned system may be applied to, for example, a record of a visitor (viewer)'s visit to an exhibition booth at an exhibition or the like. For example, a fixed station 10 is installed in an exhibition booth, and a customer carries a mobile station 30 by lending, for example. The closer the customer is to the exhibition booth, the stronger the received radio wave intensity of the beacon signal at the mobile station 30. Therefore, for example, it is possible to record the time when the customer stopped by the exhibition booth and the time when the customer stayed.

Further, by dividing the exhibition booth into an area A having a high received radio wave strength and an area B having a low reception radio wave strength, it is possible to determine the proximity to the exhibits arranged in the area A in which the exhibition booth is divided. Therefore, for example, in the exhibition booth, it is possible to record and specify the interest of the customer and the proximity to the exhibit having a high degree of interest (for example, the time of direct contact or the time of being involved with the explanation staff of the exhibit).

Further, the above-mentioned system may be applied to, for example, work records in factories and maintenance sites. For example, by attaching the transmitter 10 to each of the trolleys and trays that are the targets of maintenance and work, the time and maintenance required for the work by the workers and maintenance personnel who carry the receiver 30 for each trolley and tray. You can record the time taken for the operation.

As described above, the system according to each of the above-described embodiments can be used in a "location-free" manner regardless of the network to which the transmitter can be connected and the presence or absence of a power source, for both the transmitter 10 and the receiver 30. Therefore, for example, the transmitter 10 can be easily installed on a wheelchair or attached to a trolley or tray in a factory or the like, and is highly practical.

The present disclosure is suitable, for example, for information and communication technology that supports long-term care records in long-term care services.
