  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The flow line information collection system 10 according to the present embodiment collects flow line information of residents living in facilities such as hospitals and nursing homes. As shown in FIG. 1, the flow line information collection system 10 includes a setting information storage unit 11, a current information storage unit 12, a flow line information storage unit 13, a calculation unit 14, and a plurality of sensors D01 to D12. Yes.

  The sensors D01 to D12 are human sensors such as infrared sensors. As shown in FIG. 2, the sensors D01 to D12 are distributed and installed in the facility. Sensor D01 detects the presence of a resident in detection range A01. Each of the sensors D02 to D12 detects the presence of a resident in each of the detection ranges A02 to A12.

  The room RA shown in FIG. 2 is a private space (private room) dedicated to the resident MA. Similarly, the room RB is a private space dedicated to the resident MB, and the room RC is a private space dedicated to the resident MC. In addition, the living room RL and the toilet RW are shared spaces where any resident can enter and exit.

  The detection ranges A01 to A12 do not overlap each other. Further, this facility has no area other than the detection ranges A01 to A12. That is, a resident present in the facility is detected by at least one of the sensors D01 to D12.

  Hereinafter, a sensor in which a detection range is in contact with one sensor is referred to as an adjacent sensor. For example, the sensors adjacent to the sensor D02 are the sensor D01 and the sensor D09. The sensor D04 is not adjacent to the sensor D02 because there is a wall between the sensor D02 and the sensor D02.

  In addition, a state in which each of the sensors D01 to D12 detects the presence of a resident is simply referred to as an on state below. Each of the sensors D01 to D12 in the on state transmits a high level signal to the calculation unit 14. On the other hand, a state where each of the sensors D01 to D12 does not detect the presence of a resident is simply referred to as an off state below. Each of the off-state sensors D01 to D12 transmits a low-level signal to the calculation unit 14.

  As shown in FIG. 3, the setting information storage unit 11 is arranged in a resident ID (resident ID), a room ID (room ID) that is a private space of the resident, and the room. The ID of the existing sensor (sensor ID) and the ID of the adjacent sensor of this sensor are stored in association with each other. In addition, the setting information storage unit 11 stores an ID of a room other than the personal space, an ID of a sensor that detects a resident in the room, and an ID of an adjacent sensor of the sensor in association with each other.

  For the sake of explanation, the resident ID and the reference numeral assigned to the resident are the same. Similarly, the room ID and the code are common, and the sensor ID and the code are common.

  As shown in FIG. 4, the current information storage unit 12 stores the sensor ID and the resident ID candidate currently detected by the sensor in association with each other. For example, when the resident ID detected by the sensor D09 is specified as “MB”, the current information storage unit 12 stores the record shown in FIG. When the ID of the resident detected by the sensor D09 is either “MA” or “MB”, the current information storage unit 12 sets the sensor ID “D09” and the resident ID “MA”. A record associated with is further stored.

  The flow line information storage unit 13 stores the flow line information as shown in FIG. The flow line information according to the present embodiment includes a sensor ID, a resident ID candidate detected by the sensor, a room ID in which the sensor is disposed, and the date and time when the sensor is turned on. And the flow line ID are associated with each other.

  The flow line ID is an ID given when a resident who has moved cannot be identified as one person. For example, when one of the tenants MA and MB is detected by the sensor D02, the flow line information storage unit 13 stores the resident IDs “MA” and “MB”, the sensor ID “D02”, and the flow line ID. Is stored.

  Further, when the resident who has moved is specified as one person, the flow line ID is not given as shown in FIG. The flow line information storage unit 13 stores the route along which the resident moved through the room by accumulating the flow line information.

  The calculation unit 14 monitors signals transmitted from the sensors D01 to D12. In addition, the calculation unit 14 executes processing described later based on data stored in the setting information storage unit 11, the current information storage unit 12, and the flow line information storage unit 13.

  Next, processing executed by the flow line information collection system 10 having the above components will be described.

  The flow line information collection system 10 starts processing at a time when the resident is highly likely to exist in the personal space. The time when the flow line information collection system 10 starts processing is, for example, 4 am every morning.

  First, the calculation part 14 acquires ID of the sensor of an ON state (step S1). The calculation unit 14 acquires a room ID corresponding to the sensor ID from the setting information storage unit 11 (step S2). The computing unit 14 determines whether or not this room is a personal space (step S3).

  When it determines with it being a personal space (step S3; Yes), the calculating part 14 acquires the resident ID corresponding to this room ID from a setting information storage part (step S4). And the calculating part 14 matches resident ID and sensor ID, and memorize | stores it in the present information storage part 12 (step S5).

  For example, it is assumed that the sensors D02 and D04 are on at 4 am. The rooms RA and RB corresponding to the two sensors are private spaces. Therefore, the calculation unit 14 stores the ID “MA” of the resident living in the room RA and the sensor ID “D02” in the current information storage unit 12 in association with each other. Further, the calculation unit 14 stores the ID “MB” of the resident living in the room RB and the sensor ID “D04” in the current information storage unit 12 in association with each other.

  On the other hand, when it is determined in step S3 that it is not a personal space (step S3; No), the calculation unit 14 stores the ID of the resident who is not in the personal space and the sensor ID in association with each other in the current information storage unit 12. (Step S6).

  For example, when the sensor D06 is on in addition to the sensors D02 and D04, the calculation unit 14 determines that the resident MC does not exist in the personal space because the sensors D07 and D08 are off. Then, the calculation unit 14 associates the resident MC not in the personal space with the sensor D06, and further stores it in the current information storage unit 12.

  Next, the calculation unit 14 determines whether there is a sensor whose state has changed (step S7). When it determines with there being no sensor which the state changed, (step S7; No) and the calculating part 14 perform step S7 again. In this way, the calculation unit 14 repeatedly executes step S7, for example, every 100 ms until it is determined that there is a sensor whose state has changed.

  When it is determined that there is a sensor whose state has changed (step S7; Yes), the calculation unit 14 determines that a resident has moved from one detection range to a detection range adjacent to the detection range, and performs processing. The process proceeds to step S8.

  If the determination in step S7 is affirmed due to the movement of the resident, there are three types as shown in FIGS.

  The first type is a case where, as shown in FIG. 7A, a resident who was present in the detection range of the movement source moves to a detection range in which no one was present. In this case, the state of the sensor in the detection range of the movement source transitions from the on state to the off state. Further, the state of the sensor in the detection range of the movement destination transitions from the off state to the on state.

  The second type is a case where, as shown in FIG. 7B, one of a plurality of residents present in the detection range of the movement source moves to a detection range in which no one exists. In this case, the state of the movement source sensor remains on and does not change. Further, the state of the sensor in the detection range of the movement destination transitions from the off state to the on state.

  As shown in FIG. 7C, the third type is a case where a resident who was present in the detection range of the movement source moves to a detection range in which someone is present. In this case, the state of the sensor in the detection range of the movement source transitions from the on state to the off state. The state of the sensor in the destination detection range remains on and does not transition.

  FIG. 7D shows a case where one of a plurality of residents who existed in the detection range of the movement source moves to the detection range in which someone is present. In this case, the state of the movement source sensor and the movement destination sensor remains in the on state and does not transition. Therefore, when the resident moves as shown in FIG. 7D, the determination in step S7 is negative.

  Returning to FIG. 6, in step S <b> 8, the calculation unit 14 executes a movement destination sensor ID acquisition process (step S <b> 8). The destination sensor ID acquisition process will be specifically described with reference to FIG.

  First, the calculation unit 14 determines whether or not there is a sensor that has transitioned from an on state to an off state (step S21).

  When it is determined that there is a sensor that has transitioned from the on state to the off state (step S21; Yes), the calculation unit 14 determines whether or not there is only one sensor that has transitioned (step S22).

  When it is determined that there is only one sensor whose state has changed (step S22; Yes), the arithmetic unit 14 shifts the process to step S23. That is, among the three types shown in FIGS. 7A to 7C, in the case shown in FIG. 7C, the arithmetic unit 14 shifts the processing to step S23.

  In step S23, the calculation unit 14 acquires the ID of the sensor in the on state among the adjacent sensors that have transitioned from the on state to the off state (step S23). Then, the calculating part 14 complete | finishes a movement destination sensor ID acquisition process.

  In addition, when it is determined in step S21 that there is no sensor that has transitioned from the on state to the off state (step S21; No), it is determined that there is not only one sensor that has transitioned in step S22. In a case (step S22; Yes), the calculating part 14 transfers a process to step S24. That is, among the three types shown in FIGS. 7A to 7C, in the case shown in FIGS. 7A and 7B, the arithmetic unit 14 proceeds to step S24.

  In step S24, the calculation unit 14 acquires the ID of the sensor that has transitioned from the off state to the on state (step S24). Then, the calculating part 14 complete | finishes a movement destination sensor ID acquisition process.

  Through the above destination sensor ID acquisition processing, the calculation unit 14 acquires the sensor ID of the destination detection range in any of the three types shown in FIGS. 7A to 7C.

  Returning to FIG. 6, following step S <b> 8, the calculation unit 14 executes a mobile resident ID candidate acquisition process (step S <b> 9). This moving resident ID candidate acquisition process will be described in detail with reference to FIG.

  First, the computing unit 14 determines whether or not there is a sensor that has transitioned from the off state to the on state (step S31).

  When it is determined that there is a sensor that has transitioned from the off state to the on state (step S31; Yes), the computing unit 14 determines whether or not there is only one sensor whose state has transitioned (step S32).

  When it is determined that there is only one sensor whose state has changed (step S32; Yes), the arithmetic unit 14 proceeds to step S33. That is, in the case shown in FIG. 7B among the three types shown in FIGS. 7A to 7C, the arithmetic unit 14 shifts the processing to step S33.

  In step S33, the calculation unit 14 acquires the ID of the adjacent sensor of the sensor that has transitioned from the off state to the on state from the setting information storage unit 11 (step S33).

  Next, the calculation unit 14 acquires all the resident IDs detected by the adjacent sensors from the current information storage unit 12 (step S34).

  The calculation unit 14 acquires the flow line ID corresponding to any of the resident IDs and having the latest date and time from the flow line information storage unit 13 (step S35). In addition, when the flow line ID corresponding to this resident is not memorize | stored in the flow line information storage part 13, the calculating part 14 acquires empty data as flow line ID.

  The computing unit 14 creates a flow line ID (step S36). Specifically, the computing unit 14 creates a flow line ID by adding 1 to the flow line ID acquired in step S35, and holds this flow line ID. Thereafter, the calculation unit 14 ends the mobile resident ID candidate acquisition process.

  When it is determined in step S31 that there is no sensor that has transitioned from the off state to the on state (step S31; No), and when it is determined in step S32 that there is not only one sensor that has transitioned ( Step S32; No), the calculating part 14 transfers a process to step S37. That is, among the three types shown in FIGS. 7A to 7C, in the case shown in FIGS. 7A and 7C, the arithmetic unit 14 proceeds to step S37.

  In step S37, the calculation unit 14 acquires the ID of the sensor that has transitioned from the on state to the off state (step S37).

  Next, the calculation unit 14 acquires the resident ID detected by the sensor from the current information storage unit 12 (step S38).

  Then, the calculation unit 14 acquires the flow line ID of the record corresponding to the resident ID and the latest date and time from the flow line information storage unit 13 and holds the flow line ID (step S39). . When the flow line ID corresponding to the resident ID is not stored in the flow line information storage unit 13, the calculation unit 14 acquires empty data as the flow line ID and holds this flow line ID. To do.

  Thereafter, the calculation unit 14 ends the mobile resident ID candidate acquisition process.

  By the above moving resident ID candidate acquisition process, the calculation unit 14 acquires the ID candidate of the moved resident in any of FIGS. In addition, as illustrated in FIG. 7B, the calculation unit 14 creates a flow line ID when it is not possible to specify which of the plurality of residents has moved (step S36). In addition, when the resident moves as shown in FIGS. 7A and 7C, the calculation unit 14 acquires a flow line ID corresponding to the resident ID.

  Returning to FIG. 6, the calculating part 14 performs a flow line information registration process following step S9 (step S10). This flow line information registration process will be described in detail with reference to FIG.

  First, if there is a sensor that has transitioned from the on state to the off state, the calculation unit 14 deletes the record corresponding to the sensor ID from the current information storage unit 12 (step S41).

  Next, the computing unit 14 associates the sensor ID acquired in the destination sensor ID acquisition process with the resident ID acquired in the moving resident ID candidate acquisition process, and stores it in the current information storage unit 12. (Step S42).

  The calculation unit 14 acquires the current date and time (step S43).

  The calculation unit 14 acquires a room ID corresponding to the sensor ID acquired in the destination sensor ID acquisition process (step S44). That is, the calculation unit 14 acquires the ID of the room in which the acquired ID sensor is provided from the setting information storage unit 11.

  And the calculating part 14 is acquired by the date acquired in step S43, the room ID acquired in step S44, the sensor ID acquired in the destination sensor ID acquisition process, and the moving resident ID candidate acquisition process. A record in which the resident ID and the flow line ID are associated is registered in the flow line information storage unit 13 (step S45).

  Thereafter, the calculation unit 14 ends the flow line information registration process. Through the above flow line information registration processing, the data in the current information storage unit 12 is updated to the latest data, and a flow line information record is added to the flow line information storage unit 13.

  Returning to FIG. 6, following step S <b> 10, the calculation unit 14 executes a resident identification process (step S <b> 11). This resident identification process will be described in detail with reference to FIG.

  First, the calculation unit 14 determines whether or not there is a sensor that has transitioned from the off state to the on state (step S51).

  When it determines with there being no sensor which changed to the ON state from the OFF state (step S51; No), the calculating part 14 complete | finishes a resident identification process. That is, among the three types shown in FIGS. 7A to 7C, in the case shown in FIG. 7C, the calculation unit 14 ends the resident identification process.

  When it is determined that there is a sensor that has transitioned from the off state to the on state (step S51; Yes), the calculation unit 14 determines whether the room in which the sensor is disposed is a personal space (step). S52).

  When it determines with it not being a personal space (step S52; No), the calculating part 14 complete | finishes a tenant specific process.

  When it determines with it being a personal space (step S52; Yes), the calculating part 14 acquires ID of the resident corresponding to this room (step S53). That is, the calculation unit 14 acquires the ID of the resident who lives in this room from the setting information storage unit 11.

  The calculation unit 14 acquires the flow line ID of the record corresponding to this resident ID and having the latest date and time from the flow line information storage unit 13 (step S54). In addition, when this flow line ID is not memorize | stored in the flow line information storage part 13, the calculating part 14 acquires empty data.

  Next, the calculation unit 14 sets the resident IDs and flow line IDs of all records corresponding to any of the flow line IDs acquired in step S54 among the records stored in the flow line information storage unit 13. Is updated (step S55). Specifically, the calculation unit 14 updates the resident ID of this record to the resident ID acquired in step S53, and deletes the flow line ID data. In addition, the calculation part 14 does not update flow line information, when empty data are acquired in step S54. Thereafter, the calculation unit 14 ends the resident identification process.

  Through the above resident identification process, the resident who has entered the personal space is identified as a resident who resides in this personal space.

  Returning to FIG. 6, the calculation unit 14 that has executed Step S <b> 11 repeats the processes of Steps S <b> 7 to S <b> 11.

  Then, the process of step S7-S11 performed in a specific example is demonstrated. In this specific example, it is assumed that the resident MB exists in the detection range A09 and the resident MA has moved from the detection range A02 to the detection range A09. Further, it is assumed that the setting information storage unit 11 stores data shown in FIG. Similarly, it is assumed that the record shown in FIG. 4 is stored in the current information storage unit 12 and the record shown in FIG. 5 is stored in the flow line information storage unit 13.

  First, since the state of the sensor D02 transitions from the on state to the off state, the calculation unit 14 affirms the determination in step S7 and executes step S8. In step S <b> 8, the calculation unit 14 acquires the ID “D09” of the destination sensor.

  Next, in the mobile resident ID candidate acquisition process, the calculation unit 14 acquires the resident ID “MA” detected by the sensor D02 that has transitioned from the on state to the off state (step S38). In step S39, the calculation unit 14 acquires empty data as the flow line ID because the record corresponding to the resident MA is not stored in the flow line information storage unit 13.

  The computing unit 14 deletes the record corresponding to the sensor D02 that has transitioned from the on state to the off state from the current information storage unit 12 (step S41). Further, the calculation unit 14 stores the sensor ID “D09” and the resident ID “MA” in the current information storage unit 12 in association with each other (step S42).

  In step S44, the calculation unit 14 acquires the ID “RL” of the room (living room) corresponding to the sensor D09 from the setting information storage unit 11 (step S44).

  Then, the calculation unit 14 associates the date and time acquired in step S43 with the resident ID “MA”, the room ID “RL”, and the sensor ID “D09” and registers them in the flow line information storage unit 13. To do. The registered flow line ID is empty data acquired in step S39.

  Since no sensor has transitioned from the off state to the on state, the determination in step S51 is negative. The calculation unit 14 ends the resident identification process.

  Next, the process of steps S7 to S11 executed following the above specific example will be described. Here, it is assumed that the resident MA has moved to the detection range A02 among the resident MA and MB existing in the detection range A09.

  First, since the state of the sensor D02 transitions from the off state to the on state, the calculation unit 14 affirms the determination in step S7 and executes step S8. In step S8, the calculation unit 14 acquires the ID “D02” of the destination sensor.

  Next, in the moving resident ID candidate acquisition process, the calculation unit 14 acquires IDs “D01” and “D09” of adjacent sensors of the sensor D02 that has transitioned from the off state to the on state (step S33).

  The calculation unit 14 acquires all the IDs of the tenants detected by the sensor D01 and the sensor D09 (step S34). That is, the calculation unit 14 acquires the resident IDs “MA” and “MB” corresponding to the sensor ID “D09” from the current information storage unit 12.

  Since the flow line ID corresponding to one of the resident IDs “MA” and “MB” is not stored in the flow line information storage unit 13, the calculation unit 14 acquires empty data as the flow line ID (step S35). Since the calculation unit 14 has acquired empty data, it regards this data as ID “0” and creates a new flow line ID “1” (step S36).

  In the flow line information registration process, the calculation unit 14 stores the resident ID “MA” and the sensor ID “D02” in the current information storage unit 12 in association with each other. In addition, the calculation unit 14 stores the resident ID “MB” and the sensor ID “D02” in the current information storage unit 12 in association with each other (step S42).

  In addition, the calculation unit 14 acquires the ID “RA” of the room corresponding to the sensor D02 (step S44). Thereafter, the calculation unit 14 obtains the date and time acquired in step S43, the resident IDs “MA” and “MB”, the room ID “RA”, the sensor ID “D02”, and the flow line ID “1”. Corresponding information is stored in the flow line information storage unit 13 (step S45).

  In the resident identification process, the calculation unit 14 affirms the determinations in step S51 and step S52. Next, the computing unit 14 acquires a resident ID “MA” corresponding to the room ID “RA” (step S53). The calculation unit 14 acquires the flow line ID “1” of the record corresponding to the resident ID “MA” and having the latest date and time from the flow line information storage unit 13 (step S54).

  Then, the calculation unit 14 updates the resident ID of the record including the flow line ID “1” to one resident ID “MA”. Further, the calculation unit 14 updates the flow line ID of this record to empty data (step S55).

  As described above, the flow line information collection system 10 according to the present embodiment stores the sensor ID and the resident ID candidate detected by the sensor in association with each other in the flow line information storage unit 13. Is done. If there is a sensor whose state has changed in step S7, the data in the flow line information storage unit 13 is updated in step S10. And if the sensor arrange | positioned in a resident's personal space (private room) changes to an ON state, the resident detected by this sensor will be identified by the resident who resides in a personal space, and a flow line information storage part 13 data are updated.

  As a result, the flow line information collection system 10 collects only the information on the movement of the resident between the detection ranges of the sensors without monitoring all the resident's actions or tracking the resident's walking trajectory. To do. That is, it is possible to collect the flow line information of residents who do not carry a special device without harming privacy.

  Although the embodiment has been described above, the present invention is not limited to the above-described embodiment.

  For example, although the sensors D01 to D12 according to the above embodiment are infrared sensors, they may be sensors that detect light having a wavelength other than infrared light. Moreover, the sensor which detects sound waves, such as an ultrasonic wave, and another human sensor may be sufficient.

  The flow line information storage unit 13 stores data including data stored in the current information storage unit 12. Therefore, the flow line information collection system 10 may be configured without the current information storage unit 12. In this case, for example, the processing in which the calculation unit 14 refers to the current information storage unit 12 in the above embodiment may be replaced with the processing in which the calculation unit 14 refers to the flow line information storage unit 13.

  In step S36, the calculation unit 14 according to the above embodiment adds 1 to the largest flow line ID stored in the flow line information storage unit 13, and the movement acquired in step S35. A new flow line ID may be created by combining with the line ID.

Program H8 and communication content data are stored in advance. Further, the auxiliary storage unit H3 supplies the data stored in the program H8 to the processor H1 according to the instruction from the processor H1, and stores the data supplied from the processor H1. The auxiliary storage unit H3 physically realizes the setting information storage unit 11, the current information storage unit 12, and the flow line information storage unit 13.

  The output unit H4 includes a display device composed of an LCD (Liquid Crystal Display) or the like, an acoustic device or a printing device composed of a speaker or the like, and provides various information to the user. For example, the output unit H4 displays the data stored in the setting information storage unit 11, the current information storage unit 12, or the flow line information storage unit 13 to the administrator of the flow line information collection system 10.

  The input unit H5 includes a pointing device such as a keyboard and a mouse, and an interface device that connects the keyboard and pointing device to the internal bus H7. For example, the user of the flow line information collection system 10 rewrites the information in the setting information storage unit 11 via the input unit H5.

  The transmission / reception unit H6 includes a modem or network termination device, and a serial interface or LAN interface connected thereto. For example, the transmission / reception unit H6 acquires the detection results output from the sensors D01 to D12.

  The processing executed by the calculation unit 14 of the flow line information collection system 10 shown in FIG. 1 includes a program H8, a processor H1, a main storage unit H2, an auxiliary storage unit H3, an output unit H4, an input unit H5, a transmission / reception unit H6, and the like. It is executed by processing using as a resource.

  The function of the flow line information collection system 10 according to the above-described embodiment can be realized by dedicated hardware or by a normal computer system.

  For example, the program H8 stored in the auxiliary storage unit H3 can be read by a computer such as a flexible disk, CD-ROM (Compact Disk Read-Only Memory), DVD (Digital Versatile Disk), and MO (Magneto-Optical disk). By storing and distributing in a recording medium and installing the program H8 in a computer, an apparatus that executes the above-described processing can be configured.

  Further, the program H8 may be stored in a disk device or the like included in a predetermined server device on a communication network such as the Internet, and may be downloaded onto a computer, for example, superimposed on a carrier wave.

  The above-described processing can also be achieved by starting and executing the program H8 while transferring it through the communication network.

  Further, the above-described processing can also be achieved by executing all or part of the program H8 on the server device and executing the program H8 while the computer transmits / receives information related to the processing via the communication network. .

  Note that when the above functions are realized by sharing an OS (Operating System) or when the functions are realized by cooperation between the OS and an application, only the part other than the OS may be stored in a medium and distributed. It may also be downloaded to a computer.
