The location management device comprises a location detection unit that detects the location of a terminal held by a wheelchair user, a determination unit that determines whether or not the wheelchair user has descended from the first car to an evacuation floor by earthquake control operation based on first information from the control device and the location of the terminal detected by the location detection unit, a decision unit that determines information to be provided to the wheelchair user based on first information from the control device when the determination unit determines that the wheelchair user has descended to an evacuation floor, and a notification control unit that causes the terminal to notify the information determined by the decision unit. [Effects of the Invention]

[0007] This information provision system can provide useful information to wheelchair users if they are forced to get out of their wheelchairs during an earthquake. [Brief explanation of the drawing]

[0008] [Figure 1] This figure shows an example of an information provision system in Embodiment 1. [Figure 2] This flowchart shows an example of the control device's operation. [Figure 3] This flowchart shows other examples of the control device's operation. [Figure 4] This flowchart shows an example of the operation of the location management device. [Figure 5] This figure shows an example of hardware resources for a location management device. [Figure 6] This figure shows another example of hardware resources for a location management device. [Modes for carrying out the invention]

[0009] A detailed explanation follows, with reference to the drawings. Repetitive explanations will be simplified or omitted as appropriate. In each drawing, the same reference numerals indicate the same or corresponding parts.

[0010] Embodiment 1. Figure 1 shows an example of the information provision system 1 in Embodiment 1. The information provision system 1 comprises an elevator device 2, a position management device 3, and a receiving device 4. The elevator device 2 comprises a car 5, a control device 6, and an earthquake sensor 7.

[0011] The elevator car 5 stops at multiple floors within the building. Users can ride the elevator car 5 to their desired floor. The earthquake sensor 7 outputs a detection signal when it detects a preset acceleration. The detection signal from the earthquake sensor 7 is input to the control device 6. The control device 6 controls the operation of the elevator car 5. The control device 6 includes, for example, an operation control unit 11, a communication unit 12, and a determination unit 13.

[0012] The operation control unit 11 controls various operations, including automatic operation, earthquake control operation, and diagnostic operation. Automatic operation is an operation in which the elevator car 5 responds sequentially to registered calls. Earthquake control operation is an operation in which, when an earthquake occurs, the elevator car 5 is stopped at an evacuation floor in order to evacuate the passengers inside the elevator car 5. The evacuation floor is set in advance. It is preferable that the evacuation floor be the nearest floor. Earthquake control operation is performed immediately after an earthquake occurs. Diagnostic operation is an operation in which, after an earthquake occurs, the elevator car 5 is automatically diagnosed in order to return to automatic operation. In the diagnostic operation, the presence or absence of abnormalities is determined. Diagnostic operation is performed under certain conditions after earthquake control operation.

[0013] The communication unit 12 controls the communication function of the control device 6. The control device 6 communicates with the position management device 3 via the communication unit 12. The determination unit 13 determines whether or not there is an abnormality during the diagnostic operation.

[0014] It is preferable that the location management device 3 is capable of bidirectional communication with the control device 6. For example, the location management device 3 is installed in a building where the elevator device 2 is installed. The location management device 3 may be installed in a location away from the building. The location management device 3 may be implemented with one server device or with multiple server devices. The location management device 3 may be implemented with a cloud server. The location management device 3 includes, for example, a storage unit 20, a location detection unit 21, a determination unit 22, a decision unit 23, and a notification control unit 24.

[0015] Users of this information provision system 1 possess a terminal 8. Terminal 8 can be any type of device. For example, terminal 8 is a smartphone. Terminal 8 is equipped with a display 9. Display 9 is an example of an alarm device. Terminal 8 may be equipped with alarm devices other than the display 9. For example, terminal 8 may have a UWB (Ultra-Wide Band) tag built in. Identification information for identifying terminal 8, that is, identification information for identifying the user who possesses terminal 8, is stored in the tag.

[0016] The receiving device 4 wirelessly receives information transmitted by the terminal 8. This information includes identification information. For example, the receiving device 4 is a UWB reader. It is preferable that the receiving device 4 be positioned so as to be able to receive information transmitted by the terminal 8 regardless of where the terminal 8 is located in the building where the elevator system 2 is installed. However, if the terminal 8 is located in only a portion of the building, it is not necessary for the receiving device 4 to be able to receive information transmitted by that terminal 8. In such cases, however, it is preferable that the receiving device 4 be able to receive information transmitted by the terminal 8 if the terminal 8 is located in a landing where the elevator car 5 can stop. The information received by the receiving device 4 is transmitted to the location management device 3.

[0017] The position detection unit 21 of the position management device 3 detects the position of the terminal 8, that is, the position of the user, based on the information received by the receiving device 4. For example, in the storage unit 20, for each user, the identification information of the terminal 8 and the attribute information indicating the user's attributes are stored in association with each other. When the user is using a wheelchair, the fact that the user is a wheelchair user is stored in the storage unit 20 as the attribute information. The position detection unit 21 can detect the position of the terminal 8 possessed by the wheelchair user based on the information stored in the storage unit 20. In the following description, when it is necessary to distinguish the terminal 8 possessed by the wheelchair user from the terminal 8 possessed by other users, it is denoted as "terminal 8W".

[0018] Hereinafter, referring also to FIGS. 2 to 4, the functions of the information providing system 1 will be described in detail. FIG. 2 is a flowchart showing an operation example of the control device 6. FIG. 2 shows an example in which the earthquake sensor 7 can detect the acceleration of the building in three levels.

[0019] In the control device 6, the driving control unit 11 performs automatic driving (S101). While the automatic driving is being performed, in the control device 6, it is determined whether an earthquake has occurred (S102).

[0020] As described above, FIG. 2 shows an example in which the earthquake sensor 7 can detect the acceleration of the building in three levels. When the earthquake sensor 7 detects the acceleration of the first level, it outputs the first detection signal. When the earthquake sensor 7 detects the acceleration of the second level, which is greater than the acceleration of the first level, it outputs the second detection signal. When the earthquake sensor 7 detects the acceleration of the third level, which is greater than the acceleration of the second level, it outputs the third detection signal. The acceleration of the first level, the acceleration of the second level, and the acceleration of the third level are preset.

[0021] The control device 6 may determine whether or not an earthquake has occurred by any method. For example, when a first detection signal is input from the earthquake sensor 7, the control device 6 determines that an earthquake has occurred. That is, it determines Yes in S102. If it determines Yes in S102, the operation control unit 11 performs earthquake control operation (S103). In earthquake control operation, the elevator car 5 stops, for example, at the nearest floor. When the elevator car 5 stops at the nearest floor, the doors open. However, if it determines Yes in S102 when the unmanned elevator car 5 is stopped at the landing, earthquake control operation does not have to be performed.

[0022] After the earthquake control operation is performed, the control device 6 determines the detection signals input from the earthquake sensor 7. First, it is determined whether or not the third detection signal has been input (S104). If the third detection signal has been input, S104 is determined to be Yes. If the third detection signal has not been input, S104 is determined to be No. If S104 is determined to be No, it is determined whether or not the second detection signal has been input (S105). If the second detection signal has been input, S105 is determined to be Yes. If the second detection signal has not been input, S105 is determined to be No. If S105 is determined to be No, it is determined whether or not the first detection signal has been input (S106). In S106, it is basically determined to be Yes.

[0023] If the result in S104 is Yes, car 5 will remain idle without returning to automatic operation (S107). If the result in S104 is Yes, an inspection by an elevator maintenance worker is required for car 5 to return to automatic operation. If no abnormalities are found during the inspection, the maintenance worker will manually return car 5 to automatic operation.

[0024] If the result in S105 is Yes, the operation control unit 11 performs a diagnostic operation (S108). Various data are acquired during the diagnostic operation. The determination unit 13 determines whether or not there is an abnormality based on the acquired data (S109). If there is an abnormality in the data acquired during the diagnostic operation, the result in S109 is Yes. If the result in S109 is Yes, the elevator car 5 will pause without returning to automatic operation (S107).

[0025] If the diagnostic operation is completed without detecting any abnormalities, the result is determined as "No" in S109. If the result is determined as "No" in S109, the operation control unit 11 resumes automatic operation (S110). Note that after automatic operation resumes in S110, maintenance personnel may perform verification work.

[0026] If the result in S106 is Yes, then it is determined whether a certain amount of time has elapsed (S111). For example, if a certain amount of time has elapsed since the end of earthquake control operation, then the result in S111 is Yes. If the result in S111 is Yes, the operation control unit 11 resumes automatic operation (S112).

[0027] Figure 3 is a flowchart showing another example of the operation of the control device 6. The process shown in S201 in Figure 3 is the same as the process shown in S102 in Figure 2. If Yes is determined in S201, the communication unit 12 transmits operation information (first information) indicating the operating status of the car 5 to the position management device 3 (S202).

[0028] If earthquake-controlled operation has started in S103, the operating status may include that earthquake-controlled operation is being performed, that elevator car 5 is moving to the nearest floor under earthquake-controlled operation, or that elevator car 5 has stopped at the nearest floor under earthquake-controlled operation. If the result in S104 is Yes, the operating status may include that elevator car 5 is idle, i.e., automatic operation has not resumed. If the result in S105 is Yes, the operating status may include that diagnostic operation is being performed, that automatic operation will resume if no abnormality is detected during the diagnostic operation, that automatic operation will not resume because an abnormality was detected during the diagnostic operation, or that the diagnostic operation has ended without any abnormality being detected. If the result in S106 is Yes, the operating status may include that automatic operation will resume without performing a diagnostic operation. Examples of operating status are not limited to these.

[0029] Figure 3 shows a preferred example in which the transmission of operational information to the position management device 3 begins after an earthquake occurs. As another example, the transmission of operational information to the position management device 3 may also occur while automatic operation is in progress.

[0030] Figure 4 is a flowchart showing an example of the operation of the position management device 3.

[0031] The position management device 3 determines whether or not it has received operation information from the control device 6 of the elevator device 2 (S301). If the operation information transmitted by the communication unit 12 in S202 is received by the position management device 3, it is determined as Yes in S301.

[0032] If the determination in S301 is Yes, the determination unit 22 determines whether the wheelchair user has disembarked from the elevator car 5 to the evacuation floor due to earthquake-controlled operation (S302). If the determination unit 22 determines that the wheelchair user has disembarked from the elevator car 5 to the evacuation floor due to earthquake-controlled operation, the determination in S302 is Yes. The determination unit 22 makes the determination in S302 based on the operation information received from the control device 6 and the position of the terminal 8W detected by the position detection unit 21. For example, if the control device 6 receives operation information indicating that the elevator car 5 has stopped at the nearest floor due to earthquake-controlled operation, and the position detection unit 21 detects that the terminal 8W has moved from the elevator car 5 to the landing of the nearest floor, the determination unit 22 determines Yes in S302.

[0033] If the answer is Yes in S302, the decision unit 23 determines the information to be provided to the wheelchair user (S303). Hereinafter, this information will also be referred to as the provided information. Based on the driving information received from the control device 6, the decision unit 23 determines the provided information in S303.

[0034] For example, if the operating information includes information indicating that the result in S104 was "Yes", the decision unit 23 may include in the provided information that the elevator cannot be used because car 5 is out of service.

[0035] If the operation information includes information indicating that a diagnostic operation will be started, the decision unit 23 may include in the provided information that the diagnostic operation will start soon. If the operation information includes information indicating that a diagnostic operation has already started, the decision unit 23 may include in the provided information that a diagnostic operation is currently underway and that the elevator will be usable if no abnormalities are detected during the diagnostic operation.

[0036] If the operation information includes information indicating that an abnormality was detected during the diagnostic operation, the decision unit 23 may include in the provided information that the elevator has become unusable due to the detected abnormality. If the operation information includes information indicating that the diagnostic operation was completed without any abnormality being detected, the decision unit 23 may include in the provided information that the elevator has been confirmed to be normal and will soon be usable.

[0037] If the operating information includes information indicating that the decision in S106 was "Yes," the decision unit 23 may include in the provided information that the elevator will be usable after a few minutes. It is preferable that the decision unit 23 decides to provide information that is useful for wheelchair users who have been forcibly removed from the elevator car 5 due to earthquake control operation to decide on their subsequent actions.

[0038] The notification control unit 24 processes the information to be provided, which was determined by the decision unit 23 in S303, to be notified from the terminal 8W of a wheelchair user who has descended to an evacuation floor during earthquake control operation (S304). As an example, the notification control unit 24 transmits the information to be provided, which was determined by the decision unit 23, to the terminal 8W. As a result, the information to be provided is displayed on the display 9 of the terminal 8W. The wheelchair user can then decide on their next course of action by looking at the information to be provided displayed on the display 9 of the terminal 8W.

[0039] For example, if display unit 9 shows "The elevator will be available shortly," wheelchair users can wait at their current landing with peace of mind. Also, if display unit 9 shows "The elevator will be available if no abnormalities are detected during the diagnostic run," wheelchair users can wait where they are or ask others for assistance if necessary. If display unit 9 shows "The elevator is unavailable due to an abnormality," wheelchair users can ask others for assistance or contact acquaintances.

[0040] In the example shown in this embodiment, if an earthquake occurs and a wheelchair user is forced to get out of the car 5, useful information can be provided to the wheelchair user. In particular, in the example shown in this embodiment, information corresponding to the operating status of the car 5 can be displayed on the display 9 of the terminal 8W.

[0041] The following describes other functions that this information provision system 1 can employ. If possible, the information provision system 1 may employ a combination of the following functions.

[0042] In S303, the decision unit 23 may determine the information to be provided to the wheelchair user based on the driving information received from the control device 6 and the position of the terminal 8W detected by the position detection unit 21. In this example, information corresponding to the driving status of the car 5 and the current position of the wheelchair user can be displayed on the display 9 of the terminal 8W and communicated to the user.

[0043] For example, if the operating information includes information indicating that the diagnostic operation has been completed without detecting any abnormalities, and a wheelchair user is near the landing, the decision unit 23 may include in the provided information that the elevator will soon be available for use. On the other hand, if the wheelchair user is far from the landing, the decision unit 23 may include in the provided information, in addition to the above, a map showing directions to the elevator landing.

[0044] As an additional function, the information provided by the decision unit 23 in S303 may include an estimated time until the car 5 returns to autonomous driving. In this example, the wheelchair user can get an idea of ​​the approximate time until autonomous driving resumes, making it easier for them to decide on their next course of action.

[0045] As an additional function, the position management device 3 may also be equipped with a request unit 25. When the elevator car 5 returns to automatic operation, the request unit 25 sends a first call request to the control device 6 to call the elevator car 5 to the floor where the wheelchair user is located, i.e., the evacuation floor in earthquake control operation. The decision in S102 to "Yes" will restart the automatic operation that had been temporarily stopped, which can be determined based on the operation information received from the control device 6.

[0046] Upon receiving the first call request, the control device 6, in the resumed automatic operation, has the operation control unit 11 perform the necessary control in response to the first call request. Specifically, the operation control unit 11 stops the elevator car 5 on the floor that was designated as the evacuation floor and opens the doors. This allows the wheelchair user to board the elevator car 5 and proceed to their destination floor. In this example, the wheelchair user's call to their destination floor may be automatically registered. The wheelchair user's destination floor can be determined from the calls registered immediately before the earthquake control operation was initiated.

[0047] In this embodiment, an example was described in which the control device 6 controls one elevator car 5. In other examples, the control device 6 may also have a group control function. That is, the control device 6 may control multiple elevator cars 5. As an example, let's consider the simplest example in which the control device 6 controls the operation of elevator car 5A and elevator car 5B. In this case, the operation flows shown in Figures 2 to 4 are performed for each of elevator cars 5A and elevator car 5B.

[0048] Furthermore, if a wheelchair user is disembarked from car 5A to an evacuation floor during earthquake-controlled operation, the decision unit 23 may, in S303, determine the information to be provided to the wheelchair user based on the operation information of car 5A and car 5B received from the control device 6. For example, if car 5B can stop at the evacuation floor and car 5B returns to automatic operation faster than car 5A returns to automatic operation, the information to be provided to the wheelchair user may include guidance encouraging them to board car 5B. In this case, the request unit 25 may transmit a second call request to the control device 6 to call car 5B to the evacuation floor. This allows the wheelchair user to travel to their destination floor by boarding car 5B. Even if car 5B is not equipped with facilities for wheelchair users, the operation control unit 11 may perform wheelchair user-specific control on car 5B when it causes car 5B to respond to the second call request. Controls for wheelchair users may include extending the door opening time or slowing down the door opening and closing speed.
