FIG. 6 is an explanatory diagram for explaining an overview of processing executed by the information processing system. FIG. 7 is an explanatory diagram illustrating a configuration example of the transmitter 3. 7A and 7B schematically illustrate a cross-sectional view of the internal structure of the caster of the moving body C, and FIG. 7C schematically illustrates a configuration example of the power generation unit 33 incorporated in the caster. Below, the outline | summary of the process which an information processing system performs is demonstrated. In the following description, for the sake of convenience, it is assumed that the processing subject of the server 1 is the control unit 11 and the processing subject of the receiver 2 is the control unit 21.
As shown in FIG. 6, the receiver 2 is installed at a plurality of locations in the facility. For example, the reception range of the radio signal by the receiver 2 is about 30 meters, and the receiver 2 receives the identification signal from the transmitter 3 located within the reception range.

  The transmitter 3 is built in the caster of the moving body C which is a cart. Specifically, as shown in FIGS. 7A to 7C, a power generation unit 33 having a magnet 331 and a coil 332 is incorporated between a wheel 51 and a wheel cap 52 of a caster. The magnet 331 is attached to the axle 53 of the caster and rotates together with the wheel 51 around the axle 53 as a central axis. When the magnet 331 moves in the vicinity of the coil 332 by the rotation operation, an induced electromotive force is generated in the coil 332. The coil 332 supplies the generated induced electromotive force to the transmitter 31 (not shown in FIG. 7). Thereby, the transmitter 3 can transmit a radio wave with a simple configuration that does not require a battery.

  As described above, the transmitter 3 obtains an induced electromotive force by a rotating operation of a caster and transmits a radio wave. That is, the transmitter 3 transmits an identification signal for identifying itself only when the moving body C is moving. For example, when considering the moving body C shown in the “cart place” and “Gate 1” on the left and right in FIG. 6, since the moving body C is stopped, the transmitter 3 does not transmit an identification signal. Therefore, the receiver 2 installed in the vicinity of the moving body C does not receive the identification signal of the transmitter 3. On the other hand, when considering the moving body C shown between “Gate 1” and “Gate 1” in the center of FIG. 6, the transmitter 3 transmits an identification signal by the rotation operation of the caster, and the receiver 2 receives the identification signal. . The receiver 2 transfers the received identification signal data to the server 1.

  FIG. 8 is an explanatory diagram for explaining the transfer process of the identification signal. Based on FIG. 8, specific processing contents of the identification signal transfer processing via the receiver 2 will be described. The receiver 2 receives the identification signal from the transmitter 3 by the receiving unit 23. Then, the control unit 21 of the receiver 2 aggregates the identification signal data received from the transmitter 3 at regular intervals, and transfers the data to the server 1 by the transmission unit 25. Specifically, the control unit 21 temporarily records only the data received last among the identification signal data received by the receiving unit 23 within a predetermined time as a reception history, and other data received within the predetermined time. Abandon. The predetermined time is, for example, a time interval of 10 seconds. When receiving the identification signal from the transmitter 3, the control unit 21 reads the transmitter ID related to the identification signal, and whether or not the data of the identification signal related to the transmitter ID has already been recorded within a predetermined time, that is, It is determined whether an identification signal has already been received from the transmitter 3.

  When determining that it has not been received, the control unit 21 records the data related to the received identification signal in the storage unit 22. Specifically, the control unit 21 records the transmitter ID of the transmitter 3 indicated by the received identification signal, the date and time when the identification signal was received, and the like.

  When the receiving unit 23 receives an identification signal from the transmitter 3, the measuring unit 24 measures the reception intensity of the received identification signal. The control unit 21 records the reception intensity of the identification signal measured by the measurement unit 24 together.

  When it is determined that the identification signal has been received, the control unit 21 overwrites the data related to the newly received identification signal with the log data already recorded within a predetermined time. That is, the control unit 21 updates the reception history of the identification signal to the latest data. Thereby, the control part 21 records only the data received last within the predetermined time. In the following, for the convenience of explanation, the data of the identification signal recorded last by the receiver 2 within a predetermined time is referred to as “log data”.

  The control unit 21 receives identification signals from the transmitters 3, 3, 3... And records data for each identification signal. Thereby, as shown in the lower left of FIG. 8, the control unit 21 holds log data of the identification signal transmitted last from each transmitter 3, 3, 3.

  For example, the control unit 21 transmits the identification signal data recorded every predetermined time to the server 1 every second time longer than the predetermined time. The second time is, for example, one minute interval. The control unit 21 aggregates the log data of the identification signal last recorded in 10 seconds in units of 1 minute, and transfers it to the server 1. Thereby, as shown in the lower right of FIG. 8, the server 1 acquires six log data recorded in units of 10 seconds in the receiver 2 every minute. The control unit 11 acquires log data from each receiver 2, 2, 2,... Installed in the facility. The control unit 11 stores the log data transferred from the receiver 2 in the reception DB 141. Specifically, the control unit 11 includes a transmitter ID indicated by each identification signal, a receiver ID of the receiver 2 that has received each identification signal, a date and time at which each receiver 2 receives the identification signal, a reception strength of the identification signal, and the like. Various log data are stored in the reception DB 141 in association with each other.

  Returning to FIG. 6, the control unit 11 moves based on the log data related to the identification signal last received from the transmitter 3 among the log data of the identification signal stored in the reception DB 141. The location of the body C is specified. For example, the control unit 11 reads the log data with the latest reception date and time among the log data stored in association with the transmitter ID. Since the transmitter 3 transmits the identification signal only when the moving object C is moving, the identification signal received last in the receiver 2 is the point where the moving object C finally moved, that is, the current location position. It is presumed that it originated from. For example, when considering the moving body C shown in FIG. 6, the identification signal transmitted last by the transmitter 3 attached to the moving body C is “Gate 1 that the moving body C finally arrived after leaving the“ cart place ”. ” Therefore, the server 1 specifies the location of the moving object C based on the log data with the latest reception date and time, that is, the log data related to the identification signal last received by the receiver 2.

  The control unit 11 of the server 1 specifies the location of the moving object C based on the receiver ID of the receiver 2 and the reception intensity of the identification signal included in the read log data. For example, the control unit 11 specifies the location of the moving object C according to the installation location of the receiver 2 indicated by the receiver ID. As shown in FIG. 6, the receivers 2 are installed at a plurality of locations in the facility, and the reception ranges of the receivers 2 are different. Therefore, the control unit 11 determines that the moving body C is located within the reception range of the receiver 2 that has received the identification signal last, and identifies the location of the moving body C.

  For example, the control unit 11 specifies the location of the moving object C according to the reception strength of the identification signal. The control unit 11 can determine the distance between the receiver 2 that has received the identification signal and the transmitter 3 that has transmitted the identification signal based on the reception intensity of the identification signal measured by the receiver 2. Thereby, the server 1 can specify the location of the mobile object C.

  The control unit 11 of the server 1 outputs information corresponding to the location of the moving body C specified above to the terminal 4. For example, when the mobile object C is a cart used at an airport, the control unit 11 sends the following to the terminal 4 carried by the recovery operator for the recovery operator who performs the recovery operation of the mobile object C at the airport. Output information.

  FIG. 9 is an explanatory diagram illustrating an example of a display screen regarding the location of the moving object C. For example, as illustrated in FIG. 9, the control unit 11 causes the terminal 4 to display a list screen indicating the number (number) of the moving bodies C scattered at each point in the facility according to each location. For example, as illustrated in FIG. 9, the control unit 11 causes the terminal 4 to display a name indicating each point and the number of mobile bodies C scattered at each point on the terminal 4. Note that the display screen shown in FIG. 9 is an example, and for example, the control unit 11 may present the number of moving bodies C by graph display.

  In addition to the number display, the control unit 11 outputs to the terminal 4 instruction information indicating that the moving body C should be moved to a predetermined location according to the number of moving bodies C at each point. For example, as illustrated in FIG. 9, the control unit 11 outputs a sound indicating that the moving body C at a location with a large number of locations should be moved to a predetermined cart storage location. Thereby, the collection company is automatically instructed to collect the mobile object C. Note that the server 1 may output instruction information by image display instead of sound output, or may output instruction information by combining sound output and image display.

  FIG. 10 is an explanatory diagram illustrating another example of the display screen regarding the location of the moving object C. For example, when the control unit 11 of the server 1 receives a predetermined operation input (for example, input of a transmitter ID) for designating the transmitter 3 via the terminal 4, the screen shown in FIG. The said screen is a screen which shows the location of the moving body C provided with the designated transmitter 3 on the map image in the facility. The control unit 11 refers to the log data of the identification signal last received from the designated transmitter 3 and identifies the location of the moving object C. The control unit 11 superimposes a predetermined icon indicating the location of the identified mobile object C on the map image of the facility stored in advance, and outputs it to the terminal 4. Thereby, the collection company can easily grasp the location of the desired mobile object C.

  Although FIG. 10 illustrates the state where the location of only one moving body C is displayed on the map, the server 1 may display the location of all the moving bodies C on the map. Further, for example, the server 1 may display not only the location of the moving object C on the map but also the number of moving objects C located at each point.

11 and 12 are flowcharts illustrating an example of a processing procedure executed by the information processing system. Based on FIG.11 and FIG.12, the processing content which an information processing system performs is demonstrated.
The transmitter 3 provided in the moving body C transmits an identification signal according to the movement of the moving body C (step S11). Specifically, the transmitter 3 is provided inside the caster of the moving body C. As shown in FIG. 7, the power generation unit 33 of the transmitter 3 includes a magnet 331 and a coil 332, and the coil 332 generates an induced electromotive force by a rotating operation of a caster. The transmission unit 31 of the transmitter 3 obtains electric power from the power generation unit 33 and transmits a radio signal indicating identification information stored in the storage unit 32.

  The control unit 21 of the receiver 2 receives the identification signal transmitted from the transmitter 3 located within the reception range by the receiving unit 23 (step S12). The control unit 21 measures the reception intensity of the received identification signal (step S13). The control unit 21 determines whether or not the newly received identification signal is the same as the identification signal recorded within a predetermined time (step S14). When it determines with it being the same (S14: YES), the control part 21 overwrites and records the data which concern on the received identification signal (step S15). Thereby, the control unit 21 holds the log data of the identification signal last received from the transmitter 3 within the predetermined time. For example, the control unit 21 records data such as the transmitter ID indicated by the identification signal received in step S12 and the reception intensity measured in step S13. When it determines with it not being the same (S14: NO), the control part 21 newly records the data which concern on the received identification signal newly (step S16). The control unit 21 performs the processes of steps S13 to S16 on the identification signals received from the transmitters 3, 3, 3,... And records data relating to the identification signals.

  After step S15 or S16, the control unit 21 determines whether or not a predetermined time has elapsed since the log data related to the identification signal was stored last time (step S17). The predetermined time is, for example, 10 seconds. When it determines with predetermined time not having passed (S17: NO), the control part 21 returns a process to step S12. Thereby, the control part 21 receives an identification signal from the transmitter 3 at any time, and updates log data. When it determines with predetermined time having passed (S17: YES), the control part 21 preserve | saves the data of the recorded identification signal in the memory | storage part 22 (step S18). That is, the control unit 21 stores the data of the identification signal last received from each transmitter 3, 3, 3,... Within a predetermined time as one log data. The controller 21 determines whether or not a second time longer than the predetermined time has elapsed (step S19). The second time is, for example, 1 minute. When it determines with 2nd time not having passed (S19: NO), the control part 21 returns a process to step S12.

  Moving to FIG. 12, when it is determined that the second time has elapsed (S19: YES), the control unit 21 transmits the data of the identification signal recorded every predetermined time to the server 1 (step S20). The control unit 11 of the server 1 receives the identification signal data through the communication unit 13 (step S21). The control unit 11 stores the received identification signal data in the reception DB 141 (step S22). Specifically, the control unit 11 associates each data such as the date and time when the identification signal was received, the receiver ID of the receiver 2 that received the identification signal, and the reception strength of the identification signal with the transmitter ID indicated by the identification signal. Remember.

  The control unit 11 specifies the location of the moving object C based on the identification signal last received from the transmitter 3 by the receiver 2 (step S23). Specifically, the control unit 11 reads log data related to the latest reception date and time from the log data stored in the reception DB 141. For example, the control unit 11 specifies the location of the moving object C from the installation location of the receiver 2 indicated by the read log data among the plurality of receivers 2, 2, 2. Further, for example, the control unit 11 determines the location of the moving object C by determining the distance between the receiver 2 and the transmitter 3 from the reception intensity of the identification signal included in the log data.

  The control unit 11 outputs information corresponding to the specified location of the moving object C to the terminal 4 (step S24). For example, the control unit 11 totals the number (number) of moving bodies C for each installation location where the receiver 2 is installed, and outputs the total number of moving bodies C to the terminal 4. Further, for example, the control unit 11 generates an image indicating the location of each moving body C on a map in the facility and outputs the image to the terminal 4. The terminal 4 displays the information output from the server 1 (step S25), and returns the process to step S12.

  In addition, although the transmitter 3 shall transmit a radio signal unconditionally when the mobile body C moves above, this Embodiment is not limited to this. For example, the transmitter 3 is configured to transmit a radio signal only when the moving body C moves at a certain moving speed or more, that is, when the caster rotates at a certain angular speed or more and an induced electromotive force exceeding a certain value is generated. It may be. That is, the transmitter 3 only needs to be able to transmit a radio signal when the moving body C moves, and the content of the specific operating conditions for transmitting the radio signal is not particularly limited.

  In addition, the predetermined time (10 seconds) in which the receiver 2 takes log data and the second time (1 minute) in which the log data is output to the server 1 are set at regular intervals. However, the present invention is not limited to this, and the receiver 2 may accept a change for the above time interval. In this case, for example, the server 1 receives a setting input from the terminal 4 for the above time interval and notifies the receiver 2 of the input content. Thereby, for example, by setting the predetermined time for taking log data to be an interval shorter than 10 seconds, the location of the moving object C can be specified in more detail. Further, for example, by setting the predetermined time for collecting log data to an interval longer than 10 seconds, the processing load on the server 1 can be further reduced. In this way, the system can be adjusted to the actual operation.

  In the above description, the receivers 2, 2, 2... Are installed in one facility, but the receivers 2, 2, 2. For example, when this system is applied as a system for a logistics company, the receivers 2, 2, 2,... Are installed in a plurality of distribution centers that the logistics company serves as a logistics base. The server 1 acquires data related to the identification signal from the receivers 2, 2, 2,... Of each distribution center, and specifies which distribution center the mobile unit C is located. Thus, the installation location of the receivers 2, 2, 2,... Is not limited to one facility.

  Moreover, although the server 1 which specified the location of the moving body C described above outputs information to the external terminal 4 via the network N, the present embodiment is not limited to this. For example, when a personal computer is applied as the information processing apparatus 1 instead of the server 1, the personal computer itself may display the number of moving bodies C, map images, and the like.

  As described above, according to the first embodiment, the transmitter 3 generates power by the operation of the moving body C, so that the battery replacement work is unnecessary. Further, since the transmitter 3 transmits an identification signal only when the moving body C is operating, the server 1 only needs to process data when the moving body C is operating. Therefore, compared with the prior art, the amount of data processed by the server 1 can be suppressed and the processing load can be reduced. The identification signal last received by the receiver 2 from the transmitter 3 is presumed to have been transmitted from the point where the moving body C finally moved, that is, the current location. Therefore, the server 1 can specify the location of the moving object C with high accuracy by using the identification signal last received by the receiver 2. As described above, the location of the moving object C can be specified efficiently and accurately with a simple configuration.

  Further, according to the first embodiment, the receivers 2, 2, 2,... Are installed at a plurality of locations in the facility, so that the moving object C can be moved from the installation location of the receiver 2 that last received the identification signal. Can be specified.

  Further, according to the first embodiment, the location of the moving object C can be specified by the reception intensity of the identification signal.

  Further, according to the first embodiment, the receiver 2 records only the data of the last received identification signal among the identification signals received within a predetermined time, and the identification signal other than the last received identification signal is recorded. This data is discarded. Thereby, the amount of data processed by the server 1 is further suppressed, and the processing load can be reduced.

  Further, according to the first embodiment, the receiver 2 collects the log data recorded every predetermined time and transfers it to the server 1 by collecting the log data every second time, thereby efficiently with the server 1. Receive data transfer processing can be performed.

  Further, according to the first embodiment, by notifying information corresponding to the specified location of the moving body C, the convenience in collecting and using the moving body C is improved.

  Moreover, according to this Embodiment 1, the collection | recovery of the efficient mobile body C is attained by notifying the location quantity of the mobile body C located in each point.

  Further, according to the first embodiment, it is possible to collect the moving body C more efficiently by outputting the instruction information according to the location quantity of the moving body C located at each point.

  Further, according to the first embodiment, the location of the moving object C can be easily grasped by displaying the location of the moving object C on the map.

(Embodiment 2)
In the present embodiment, a mode in which the execution motion of the moving body C calculated from the identification signal is compared with a predetermined action of the moving body C that is defined in advance to estimate the progress of the moving body C will be described. In addition, about the content which overlaps with Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.
In the present embodiment, the server 1 determines from the log data of the moving body C whether or not the work schedule is being carried out as scheduled for an operator who uses the moving body C to transport and deliver articles. presume. Specifically, the case where the moving body C is a cleaning cart used for carrying a cleaning tool by a cleaning company that cleans the facility will be described as an example.

  FIG. 13 is a block diagram illustrating a configuration example of the server 1 according to the second embodiment. The mass storage device 14 of the server 1 according to the present embodiment stores a schedule table 142. The schedule table 142 stores schedule information indicating the scheduled behavior of the mobile object C. The schedule information is, for example, information that associates the contents of work performed by an operator who uses the mobile object C, points where each work is performed, and scheduled times when the work is performed at each point.

  FIG. 14 is an explanatory diagram showing an example of a record layout of the schedule table 142 according to the second embodiment. The schedule table 142 includes a transmitter ID column, a time column, a position column, a movement state column, and a work content column. The transmitter ID column stores a transmitter ID for identifying each transmitter 3 provided in each mobile body C. The time column stores each time zone of the day in association with the transmitter ID. The position column stores the location of the moving object C scheduled at each time in association with the transmitter ID and the scheduled time. The movement state column stores the movement state of the moving body C scheduled at each scheduled time, specifically, whether the moving body C is moving or stopped, in association with the transmitter ID and the scheduled time. The work content column stores work content to be performed at each time by a worker who performs work using the mobile object C in association with the transmitter ID and the scheduled time.

  FIG. 15 is an explanatory diagram for explaining the progress estimation process according to the second embodiment. In the following description, as described in the first embodiment, the transmitter 3 provided in the moving body C transmits an identification signal according to the movement of the moving body C. In other words, when the moving body C is stopped, the transmitter 3 does not transmit an identification signal. Therefore, when the moving body C is stopped, the receiver 2 does not detect the identification signal from the transmitter 3.

  When the receiver 2 does not detect the identification signal from the transmitter 3, the control unit 11 of the server 1 according to the present embodiment determines that the moving object C is stopped. Specifically, the control part 11 discriminate | determines that the mobile body C has stopped, when the non-reception time when the receiver 2 does not receive an identification signal is a fixed time or more. For example, when the identification signal from the transmitter 3 is not received for 3 minutes or more, the control unit 11 determines that the moving object C provided with the transmitter 3 is stopped. On the other hand, when the identification signal from the transmitter 3 is received within less than 3 minutes, the control unit 11 determines that the moving body C provided with the transmitter 3 is moving. As described above, the control unit 11 determines whether the moving body C is moving or stopped, that is, the moving state of the moving body C, according to the non-reception time of the identification signal.

  The control unit 11 refers to the log data transferred from the receivers 2, 2, 2,... As needed, tracks the location of the moving object C, and determines the moving state of the moving object C at each time point. Then, the control unit 11 refers to the schedule information stored in the schedule table 142 and estimates the current progress of the moving object C. Specifically, the control unit 11 compares the current location and moving state of the moving body C determined from the identification signal with the current scheduled action defined in the schedule table 142, that is, the planned position and the moving state. For example, as shown in FIG. 15, consider a case where the moving object C is stopped at “3F toilet” at “11:00”. The control unit 11 determines whether or not the current time at which the “3F toilet” is stopped is included in the scheduled time at which the “3F toilet” is stopped. In this case, in the scheduled action defined in the schedule table 142, the moving object C should have stopped at “3F toilet” from “10:30” to “10:55”, but “3F toilet” The current time of stopping at “11:00” is “11:00”. Therefore, the control unit 11 determines that the cleaning operation is delayed because the current time is delayed from the scheduled time. Therefore, the control unit 11 estimates the progress of the moving object C as “delay”.

  The control unit 11 notifies the terminal 4 of the above estimation result, that is, the progress of the moving object C. For example, as illustrated in FIG. 15, the control unit 11 outputs information indicating that the cleaning operation is delayed to the terminal 4 carried by the cleaning company. In this case, the control unit 11 outputs the estimation result related to “delay” and outputs the work content (cleaning of “4F toilet”) that should be performed at the present time. From the above, the server 1 can not only determine the movement pattern of the moving object C, but also determine the progress of the moving object C at an arbitrary time point based on the determined movement pattern, and check and improve the work efficiency. Can do.

  Although the server 1 outputs the progress status in real time as described above, for example, the log data stored in the reception DB 141 is periodically analyzed, and the progress status is collectively evaluated and output. In general, the overall work result (the progress of the moving body C) may be presented.

FIG. 16 is a flowchart illustrating an example of a processing procedure executed by the information processing system according to the second embodiment. After executing the process of specifying the location of each mobile object C (step S23), the control unit 11 of the server 1 executes the following process.
The control unit 11 refers to the log data stored in the reception DB 141 and determines whether or not the unreceived time during which no identification signal is received is less than a certain time (step S201). When it determines with it being less than fixed time (S201: YES), the control part 11 discriminate | determines that the mobile body C is moving (step S202). When it determines with it not being less than fixed time (S201: NO), the control part 11 discriminate | determines that the mobile body C provided with the said transmitter 3 has stopped (step S203). The control unit 11 performs the processing of steps S201 to S203 for each moving body C to determine the movement or stop of each moving body C.

  The control unit 11 compares the scheduled action stored in the schedule table 142 with the location specified in step S23 and the movement state determined in step S202 or S203, and estimates the progress of the moving object C (step S204). Specifically, the control unit 11 uses the moving object C by comparing the current scheduled position and moving state defined in the schedule table 142 with the current location and moving state determined from the log data. It is determined whether or not the worker is acting as scheduled. For example, when the control unit 11 specifies that the mobile object C is located at one point, the control unit 11 refers to the schedule table 142 and reads the scheduled time associated with the point (scheduled position). The control unit 11 estimates whether or not the current moving body C is progressing with respect to the scheduled action by determining whether or not the current time is included in the scheduled time. For example, when the current time is behind the scheduled time, the control unit 11 estimates the progress of the moving object C as “delayed”. The control unit 11 outputs the estimation result estimated in step S204 to the terminal 4 (step S205). The terminal 4 receives information on the progress status from the server 1 and displays it on the display screen (step S206), and returns the process to step S12.

  In the above description, the cleaning cart has been described as an example. However, the present embodiment is not limited to this. For example, it is assumed that the mobile object C is a transport cart for a delivery service of a carrier, and the server 1 may evaluate whether or not the transport cart is at a position according to the delivery schedule. That is, the moving body C is not particularly limited as long as the scheduled behavior can be defined to some extent.

  As described above, according to the second embodiment, the progress of the moving body C can be determined by comparing the scheduled action and the execution action of the moving body C.

  Further, according to the second embodiment, the progress of the moving body C can be more accurately determined by taking into account the moving state related to the movement or stop of the moving body C.

(Embodiment 3)
In the present embodiment, a mode in which information is presented according to the area where the moving body C is located will be described.
FIG. 17 is an explanatory diagram for explaining an overview of the information processing system according to the third embodiment. FIG. 17 illustrates a map diagram in the facility where the receivers 2, 2, 2,... Are installed. In this embodiment, the receivers 2, 2, 2,... Are installed at various locations in the airport lobby. Each of the receivers 2, 2, 2 receives an identification signal from transmitters 3, 3, 3.

  Server 1 according to the present embodiment determines whether or not the location of mobile object C specified by the identification signal of transmitter 3 corresponds to a specific area in the facility. When the location of the moving object C corresponds to the specific area, the server 1 presents information corresponding to the area to the user.

  For example, the control unit 11 of the server 1 determines whether or not the location of the moving object C corresponds to the prohibited area A1 where entry of the moving object C is prohibited. For example, in the case of an airport facility, the range in which a baggage cart can be used is often limited from a security standpoint. Therefore, when the user causes the mobile object C to enter the area where entry is prohibited, the server 1 notifies that entry is prohibited.

  For example, the control unit 11 outputs warning information indicating that the mobile object C has entered the prohibited area A1 to the terminal 4 used by the airport staff. Specifically, the control unit 11 outputs a predetermined warning sound to the terminal 4. For example, the control unit 11 may issue a warning by displaying an image. As a result, the server 1 prompts the airport staff to stop. For example, a device such as a speaker may be installed in the prohibited area A1, and the server 1 may output a warning sound through the speaker.

Further, for example, the control unit 11 may present the warning information not to the airport staff but to the airport user (user) who uses the moving object C. In this case, pre-registration of the terminal 4 to the server 1 by, for example, a predetermined reception device installed at the airport entrance performing near field communication with the terminal 4 or installing a dedicated application program in the terminal 4 Keep going. Further, for example, the reception device or terminal 4 described above performs wireless communication with the transmitter 3 of the mobile object C, acquires the transmitter ID, and notifies the server 1 of it. The server 1 that has received the notification performs pairing between the transmitter 3 and the terminal 4. When the moving body C enters the prohibited area A1, the control unit 11 of the server 1 outputs warning information to the terminal 4 associated with the transmitter 3 indicated by the identification signal, and moves the moving body C from the prohibited area A1. Inform the power.
As described above, the server 1 can prompt appropriate facility use by issuing a warning according to the location of the moving object C.

  Further, for example, the server 1 may determine whether the location of the moving object C corresponds to the standby area A2 of the moving object C that is defined in advance, not the area where entry is prohibited. That is, the control unit 11 of the server 1 determines whether or not the mobile object C that is a baggage cart has been returned to a predetermined cart storage area. When the mobile object C is returned to the cart storage area by the user of the airport, the recovery operator of the mobile object C (cart) does not need to perform the recovery operation, and the work load is reduced. The server 1 determines whether or not the mobile object C has been returned to the standby area A2 in order to promote the reduction of the work load. When the mobile object C is returned to the standby area A2, the server 1 rewards the user who has returned the mobile object C. give.

  For example, the control unit 11 of the server 1 outputs privilege information to the terminal 4 when it is determined that the location of the moving object C corresponds to the standby area A2. The privilege information is information for giving the user an incentive to return the moving body C to the standby area A2, and is, for example, a product coupon that can be used at a store in an airport, a mileage point that can be used for aircraft use, and the like. The control unit 11 distributes privilege information to the terminal 4 as an incentive for returning the moving body C. Thereby, the return of the moving body C by the user is prompted, and the collection work of the moving body C by the collection company can be reduced.

FIG. 18 is a flowchart illustrating an example of a processing procedure executed by the information processing system according to the third embodiment. After executing the process of specifying the location of the moving object C (step S23), the control unit 11 of the server 1 executes the following process.
The control unit 11 determines whether or not the specified location of the moving object C corresponds to the prohibited area A1 where entry of the moving object C is prohibited (step S301). When it determines with corresponding to the prohibition area A1 (S301: YES), the control part 11 outputs the warning information to the effect that the mobile body C entered prohibition area A1 to the terminal 4 (step S302). Note that the output destination of the warning information is not particularly limited. For example, the server 1 may output the warning information to a predetermined speaker or the like installed in the prohibited area A1. The terminal 4 receives the warning information from the server 1 and outputs a warning sound indicating that the mobile object C has entered the prohibited area A1 (step S303). Note that the terminal 4 may output a warning by image display instead of voice output. The terminal 4 returns the process to step S12.

  If it is determined that the area does not correspond to the prohibited area A1 (S301: NO), the control unit 11 determines whether or not the location of the mobile object C specified in step S23 corresponds to the standby area A2 of the mobile object C specified in advance. Is determined (step S304). When it determines with not corresponding to standby area A2 (S304: NO), the control part 11 returns a process to step S12. When it determines with falling under standby area A2 (S304: YES), control part 11 outputs privilege information to terminal 4 (Step S305). The privilege information is information that gives an incentive to the user returning the moving body C to the standby area A2, for example, a product coupon, a mileage point, or the like. The terminal 4 receives privilege information from the server 1 (step S306), and returns the process to step S12.

  As described above, according to the third embodiment, when the moving body C enters the prohibited area A1, the warning information is output, thereby prompting appropriate facility use.

  Moreover, according to this Embodiment 3, when the mobile body C is returned to the waiting area A2, the work burden concerning the collection | recovery operation | work of the mobile body C is reduced by giving privilege information to a user.

(Embodiment 4)
In the present embodiment, the mobile terminal C is made to function as a receiver, and the position of the moving object C is specified based on the identification signal received by the terminal 4 and the positional information of the terminal 4 when the identification signal is received. The form to do is described.
FIG. 19 is an explanatory diagram showing an outline of the fourth embodiment. In the present embodiment, it is assumed that the car used for transporting the luggage is the moving body C, assuming an application scene to the delivery business. As in the first to third embodiments, the transmitter 3 is provided on the caster of the moving body C.

  In the present embodiment, the terminal 4 receives the identification signal instead of the receiver 2. The terminal 4 is carried by an operator who performs delivery work. When the operator moves the moving body C, the transmitter 3 transmits an identification signal as the caster rotates. The terminal 4 of the worker who uses the mobile object C receives the identification signal.

  When the terminal 4 receives the identification signal, the terminal 4 acquires the position information of the own device. For example, the terminal 4 acquires position information from a GPS satellite. The terminal 4 temporarily stores position information at the time of receiving the identification signal as log data together with information such as the transmitter ID and the signal strength indicated by the identification signal. The terminal 4 transfers log data including position information to the server 1 every second time (1 minute) by the same algorithm as that of the first embodiment. The server 1 specifies the location of the moving object C based on the position information indicated by the transferred log data.

  As described above, the terminal 4 functioning as a receiver of the identification signal acquires the position information of the own apparatus, and the server 1 specifies the position of the moving object C based on the position information acquired by the terminal 4. In the first embodiment, the location of the moving object C is specified from the installation location of the receiver 2. However, in this embodiment, since the terminal 4 acquires position information, the receiver 2 does not need to be fixedly installed. , Can increase versatility.

  FIG. 20 is an explanatory diagram illustrating an example of a management screen. The server 1 generates a management screen indicating the location of each mobile body C based on the location of the mobile body C specified above and outputs the management screen to a predetermined management terminal 6. For example, the screens shown in FIGS. 20A and 20B are output.

  FIG. 20A is a map screen (map image) showing the location of each moving body C. FIG. The server 1 refers to the location of each moving body C and predetermined map information, and displays the current position of each moving body C on the map. More specifically, the server 1 displays the location of the moving body C and the locations of the delivery center, the sales office, etc., which are delivery bases, on a map. As a result, it is possible to easily grasp which delivery base each moving body C (car) is currently located.

  The server 1 not only outputs a map screen, but also generates a screen showing details of the location of the moving object C and outputs it to the management terminal 6 as shown in FIG. 20B. Specifically, the server 1 compares the position of each base set in advance with the current position of the mobile body C specified above, and displays information on the mobile body C located at each base at the top of the screen. Output. In addition, the server 1 compares the location of the mobile object C at each reception time indicated by the log data in the past several days with the position of each base, and the mobile object C is located at each base. A movement history indicating the time and base name is output at the bottom of the screen.

  As described above, in the present embodiment, the server 1 is capable of managing the mobile object C in a manner suitable for delivery work, and the location of the mobile object C (car) identified from the log data and each delivery Based on the location of the base, a management screen indicating the location of the moving body C at each delivery base is generated and output to the management terminal 6.

21 and 22 are flowcharts illustrating an example of a processing procedure executed by the information processing system according to the fourth embodiment. The processing contents according to the present embodiment will be described based on FIGS. 21 and 22.
The terminal 4 receives the identification signal from the transmitter 3 (step S12), measures the reception intensity (step S13), and acquires the position information of the own device (step S401). For example, the terminal 4 acquires position information indicating latitude and longitude from a GPS satellite. When the log data of the identification signal is temporarily recorded in step S15 or S16, the terminal 4 records the acquired position information in association with the transmitter ID and the reception time.

  Moving to FIG. 22, after the log data received from the terminal 4 is stored in the reception DB 141 (step S22), the control unit 11 of the server 1 executes the following processing. The control unit 11 specifies the location of the moving object C based on the identification signal last received by the receiver 2 and the position information of the terminal 4 when the identification signal is received (step S402). The control part 11 produces | generates the management screen which shows the specified location, and outputs it to the management terminal 6 (step S403). For example, the control unit 11 generates a map screen showing the position of each delivery base stored in advance and the location of the moving object C identified in step S <b> 402 on the map, and outputs the map screen to the management terminal 6. Further, for example, the control unit 11 generates a screen showing the location of the moving body C at each base, the movement history between the bases for each moving body C, and outputs the screen to the management terminal 6. The management terminal 6 displays the management screen (step S404), and returns the process to step S12.

  As described above, according to the fourth embodiment, the mobile terminal C is made to function as a receiver, and the location of the mobile object C is specified based on the positional information of the terminal 4 when receiving the identification signal. Thus, there is no need to install the receiver 2 as in the first embodiment, and versatility can be improved.

  In the above description, the location of the mobile object C is specified based on the location information of the terminal 4 that is a mobile terminal, but the present embodiment is not limited to this. For example, a wireless device (beacon device) may be installed at a predetermined position in each base, and the location of the moving object C may be specified based on a beacon signal (identification information) transmitted from the wireless device. That is, the terminal 4 receives a beacon signal from the transmitter 3 and also receives a beacon signal from a wireless device installed at a predetermined position of the delivery base and transfers it to the server 1 as a series of log data. The server 1 identifies the location of the moving object C from the installation position of the wireless device indicated by the beacon signal. Thus, instead of the location information of the terminal 4, the location of the moving object C is identified based on information that can identify the location of the terminal 4 (in the above, identification information of the wireless device fixedly installed). Also good.

(Embodiment 5)
In the present embodiment, a mode in which a transmitter 3a that transmits an identification signal in accordance with the vibration operation of the moving body will be described.
FIG. 23 is an explanatory diagram showing an outline of the fifth embodiment. In this embodiment, as an example, description will be made assuming an application scene in a hospital. FIG. 23 illustrates a state in which a transmitter 3 similar to that of the first embodiment is provided on a caster of an object (movable body C) such as a wheelchair or a stretcher used in a hospital. Further, FIG. 23 further illustrates a state in which a human (mobile body C) such as a patient or a hospital staff is attached with a transmitter 3a that transmits an identification signal in accordance with a vibration operation.

  FIG. 24 is an explanatory diagram showing a configuration example of the internal power supply (power generation unit 33a) of the transmitter 3a according to the fifth embodiment. Transmitter 3a according to the present embodiment includes power generation unit 33a that generates power in accordance with the vibration operation, instead of power generation unit 33 according to the first embodiment. The power generation unit 33a includes a coil 332a, a magnet 331a provided in the vicinity of the coil 332a, and a spring (elastic body) 333a connected to the magnet 331a. When the transmitter 3a vibrates due to the movement of the moving body C, the spring 333a expands and contracts, and the magnet 331a moves up and down in FIG. 23 in the vicinity of the coil 332a. With this movement, an induced electromotive force is generated between the magnet 331a and the coil 332a. The power generation unit 33 a supplies the induced electromotive force generated with the vibration to the transmission unit 31. Thus, since the transmitter 3a is driven by obtaining electric power by a vibration operation, it is not necessary to replace the battery as in the case of the rotary transmitter 3, and it can be used for a long time. The transmitter 31 of the transmitter 3a transmits an identification signal including a transmitter ID when power is supplied from the power generation unit 33a along with the vibration operation.

  Returning to FIG. 23, the receiver 2 is installed at a predetermined location in the hospital. The receiver 2 receives an identification signal from a transmitter 3 provided in a wheelchair, a stretcher or the like, and also receives an identification signal from a transmitter 3a attached by a patient, a hospital staff, or the like. In the present embodiment, the transmitter 3a is described as being worn by a person, but the transmitter 3a may be attached to an object other than a person (for example, a medical device). The receiver 2 outputs log data of the identification signal received from the transmitters 3 and 3a to the server 1.

  Based on the log data output from the receiver 2, the server 1 specifies the location of the mobile object C corresponding to each transmitter 3, 3a. Specifically, as in the first embodiment, the server 1 specifies the location from the installation location of the receiver 2 that has received the identification signal. As in the fourth embodiment, the server 1 generates a management screen indicating the location of each mobile object C and outputs the management screen to the management terminal 6.

  In this case, the server 1 generates a management screen showing the location of each moving body C in a different manner and outputs the management screen to the management terminal 6 so that the difference between the moving bodies C can be understood. Although specific illustration is omitted, for example, the server 1 is a device such as a wheelchair or a stretcher on the map screen showing the inside of the hospital, or is it a person such as a patient or a hospital staff? The position of each mobile object C is displayed by changing the color, mark, etc. according to the transmitter ID. The server 1 stores the type of the mobile object C in association with the transmitter ID, that is, whether it is a thing or a human, and when generating the management screen, the mobile object C associated with the transmitter ID. A map screen is generated with reference to the type information. In the above description, the classification is simply based on the difference between an object and a person, but it is needless to say that the classification may be performed in more detail.

  In addition, for example, the server 1 may perform an alert or the like when detecting the movement of the moving body C, for example, for measures against wrinkles of patients. That is, the server 1 may output information using the operation of the moving object C (rotation of casters or vibration of the moving object C) as a trigger.

FIG. 25 is a flowchart illustrating an example of a processing procedure executed by the information processing system according to the fifth embodiment. Based on FIG. 25, processing contents according to the present embodiment will be described.
The control unit 11 of the server 1 receives the log data of the identification signal from the transmitter 3 that transmits by the rotation operation and the transmitter 3a that transmits by the vibration operation from the receiver 2 (step S21), and stores them in the reception DB 141. (Step S22), the following processing is executed. The control unit 11 refers to the log data and specifies the location of the moving object C corresponding to each of the transmitters 3 and 3a (step S501). Specifically, as in the first embodiment, the control unit 11 specifies the location of the moving object C based on the installation location of the receiver 2 that has received the identification signal from the transmitters 3 and 3a.

  The control unit 11 generates a management screen that displays the location of each mobile object C in a different manner according to the transmitter ID of the transmitters 3 and 3 a corresponding to each mobile object C, and outputs the management screen to the management terminal 6. (Step S502). For example, in accordance with the type of the transmitters 3 and 3a indicated by the transmitter ID, the control unit 11 displays in the hospital that displays the mobile object C in different colors, marks, etc. so that it can be recognized whether it is a human or an object A map screen is generated and output to the management terminal 6. The management terminal 6 displays a management screen (step S503), and returns the process to step S12.

  As described above, according to the fifth embodiment, the same effect as that of the first embodiment can be obtained by using the transmitter 3a that transmits the identification signal along with the vibration operation. Further, by combining the rotary transmitter 3 and the vibration transmitter 3a, it is possible to selectively use according to the moving body C, and efficient and appropriate operation can be performed.

(Embodiment 6)
In the present embodiment, a description will be given of a mode in which the identification signal transmitted from the transmitter 3 includes count information indicating the transmission order of the identification signal, and the position of the moving body C is specified according to the count information.
FIG. 26 is an explanatory diagram showing an outline of the sixth embodiment. In this embodiment, the transmitter 3 transmits an identification signal including count information indicating the transmission order of identification signals in addition to the transmitter ID for identifying the device itself.

  As shown in the upper part of FIG. 26, when the moving body C moves, the moving body C transmits an identification signal at each point. In this case, the transmitter 3 counts the number of transmissions every time the identification signal is transmitted. When the transmitter 3 transmits a new identification signal, the transmitter 3 transmits the identification signal including the number of times the signal is transmitted, that is, the count information indicating the transmission order.

  The receiver 2, 2, 2... Receives an identification signal including count information from the transmitter 3. In FIG. 25, the three receivers 2, 2, 2 each receive the identification signal from the transmitter 3 a plurality of times. In FIG. 25, the numbers shown above and below each receiver 2 indicate the number of counts related to the transmission order of the identification signals received by the receiver 2.

  Here, the receiver 2 illustrated in the lower left of FIG. 26 receives the identification signal transmitted for the fifth time and the sixth time, and then receives the identification signal transmitted for the fifth time again. This is considered that the identification signal transmitted for the fifth time from the transmitter 3 is reflected on the wall, ceiling, etc. and reaches the receiver 2. Thus, the receiver 2 may receive the old signal later than the new signal. Accordingly, when the location of the moving object C is simply specified from the latest received data (identification signal), the location of the moving object C may be specified incorrectly.

  Therefore, the transmitter 3 includes the count information when transmitting the identification signal. The receiver 2 or the server 1 discriminates the latest identification signal based on the count information included in the identification signal and identifies the location of the moving object C. The receiver 2 shown in the lower left of FIG. 25 refers to the count information included in the identification signal and determines that the identification signal received for the sixth time is the latest received data. The receiver 2 records the sixth identification signal, which is the latest received data, as log data and outputs it to the server 1.

  The server 1 acquires log data of the identification signal from each receiver 2 and specifies the location of the moving object C from the log data. Here, consider a case where a plurality of receivers 2 have received the same count of identification signals. For example, in the example of FIG. 26, the three receivers 2, 2, and 2 receive the same identification signal at the sixth transmission.

  In this case, the server 1 determines the receiver 2 closest to the moving body C according to the reception intensity of the identification signal in each receiver 2 and specifies the location of the moving body C. For example, in FIG. 26, since the reception intensity at the receiver 2 located at the lower left is the maximum, the server 1 specifies the location of the moving object C based on the position of the receiver 2. Thereby, when the same identification signal is received by the plurality of receivers 2, the location of the moving object C can be appropriately specified.

  In the above description, the position of the moving object C is simply identified based on the strength of the reception intensity. However, the location of the moving object C is accurately determined from the reception intensity of the plurality of receivers 2 using a principle such as three-point positioning. May be. That is, the above processing is an example, and the server 1 only needs to be able to specify the location of the moving object C according to the reception intensity at the plurality of receivers 2.

27 and 28 are flowcharts illustrating an example of a processing procedure executed by the information processing system according to the sixth embodiment. The processing contents according to the present embodiment will be described with reference to FIGS.
The transmitter 3 transmits an identification signal including count information indicating the transmission order in addition to the transmitter ID (step S601). As described above, the transmitter 3 counts the number of transmissions every time an identification signal is transmitted. When transmitting the identification signal along with the rotation of the caster, the transmitter 3 transmits count information indicating the counted number of times together with the transmitter ID.

  When it is determined that the transmitter ID indicated by the received identification signal is an already recorded ID (S14: YES), the control unit 21 of the receiver 2 executes the following process. The control unit 21 refers to the count information included in the identification signal and determines whether or not the identification signal is the latest transmitted from the transmitter 3 (step S602). Specifically, the control unit 21 compares the count of the identification signal already recorded within a predetermined time (within the latest 10 seconds) with the count of the newly received identification signal, and the newly received identification signal is It is determined whether or not it is the latest identification signal. When it determines with it not being the newest identification signal (S602: NO), the control part 21 transfers a process to step S17. When it determines with it being the newest identification signal (S602: YES), the control part 21 overwrites and records log data with the said identification signal (step S603), and transfers a process to step S17.

  28, the control unit 11 of the server 1 stores the log data received from the receiver 2 in the reception DB 141 (step S22), and then executes the following processing. The control unit 11 refers to the log data and identifies the location of the moving object C (step S604). Here, when the identification signals having the same transmitter ID and the same count (transmission order) are recorded by the plurality of receivers 2, the control unit 11 responds to the reception intensity measured by each receiver 2. Thus, the location of the moving object C is specified. For example, the control unit 11 specifies the location of the moving object C based on the installation location of the receiver 2 having the maximum reception intensity. In addition, for example, the control unit 11 may specify a location by performing three-point positioning or the like based on the reception intensity of each of the plurality of receivers 2. The control part 11 transfers a process to step S24.

  As described above, according to the sixth embodiment, it is possible to increase the accuracy in specifying the position of the moving body C by including the count information indicating the transmission order in the identification signal.
