Description

[Technical Field]

[0001] The present disclosure relates to an elevator call registration method and an elevator control system. [Background technology]

[0002] For example, Patent Document 1 describes a method and system for identifying the boarding floor (= departure floor) of an elevator user from radio waves from a beacon installed at the landing, and registering a call to a preset destination floor. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2020 / 188635 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the method and system described in Patent Document 1 requires that a beacon be installed at the landing of each floor to identify the boarding floor. Installing dedicated equipment such as a beacon increases costs, and the more floors there are, the higher the cost of installing the equipment becomes.

[0005] Therefore, an object of the present disclosure is to provide an elevator call registration method and an elevator control system that can identify the boarding floor of an elevator user without installing dedicated equipment at the landing of each floor. [Means for solving the problem]

[0006] The elevator call registration method disclosed herein is a method for registering an elevator in which a radio wave receiving device is installed in the elevator car and multiple wireless communication devices are installed in the building in which the elevator is installed, and includes the steps of: an elevator control device creating elevator received radio wave strength information representing a wireless communication device with strong radio waves received by the radio wave receiving device for each floor at which the car stops; a mobile terminal of an elevator user creating terminal received radio wave strength information representing a wireless communication device with strong radio waves received by the mobile terminal; a mobile terminal determining whether the user is located near the elevator landing by comparing the elevator received radio wave strength information with the terminal received radio wave strength information; and a step of the mobile terminal transmitting an elevator call registration signal if it is determined that the user is located near the elevator landing.

[0007] The elevator control system of the present disclosure includes a radio wave receiving device installed in an elevator car, multiple wireless communication devices installed in a building where the elevator is installed, an elevator control device, and a mobile terminal of an elevator user. The control device generates elevator received radio wave strength information representing wireless communication devices with strong radio waves received by the radio wave receiving device for each floor where the car stops. The mobile terminal generates terminal received radio wave strength information representing wireless communication devices with strong radio waves received by the mobile terminal, and determines whether the user is located near the elevator hall by comparing the elevator received radio wave strength information with the terminal received radio wave strength information. If it is determined that the user is located near the elevator hall, the mobile terminal transmits an elevator call registration signal. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to identify the boarding floor of an elevator user without installing dedicated equipment at the landing of each floor. [Brief explanation of the drawings]

[0010] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 FIG. 1 is a diagram showing the configuration of an elevator system.

[0011] The elevator system includes an elevator 1 installed in a building, a wireless communication device 2 installed in each room of the building, and a mobile terminal 3 carried by a user of the elevator 1.

[0012] The elevator 1 includes a car 11, a drive unit 12, a control unit 13, and a radio wave receiving unit 14. The car 11 moves up and down between multiple floors of the building. The drive unit 12 raises and lowers the car 11 .

[0013] The control device 13 controls the movement of the car 11. The control device 13 is configured to be able to communicate with the radio wave receiving device 14 and the mobile terminal 3.

[0014] The radio wave receiving device 14 is installed in the car 11. The radio wave receiving device 14 is configured to be able to communicate with the control device 13 via a wired cable or wirelessly. The radio wave receiving device 14 receives radio waves from the wireless communication device 2. The radio wave receiving device 14 is configured by a wireless router, an access point, or the like.

[0015] The wireless communication device 2 is, for example, a WiF (registered trademark) wireless router connected to the Internet 4.

[0016] The mobile terminal 3 receives radio waves from the wireless communication device 2. The mobile terminal 3 is configured to be able to communicate with the control device 13 wirelessly. FIG. 2 is a diagram showing the configuration of the control device 13 according to the first embodiment. The control device 13 includes a memory 21, a processor 22, and a communication circuit 23. The communication circuit 23 can communicate with the radio wave receiving device 14 and the mobile terminal 3.

[0017] The memory 21 stores a program for operating the processor 22 and elevator received radio wave intensity information.

[0018] The processor 22 executes a program stored in the memory 21. The processor 22 creates elevator received radio wave strength information that indicates, for each floor at which the car 11 stops, the wireless communication device 2 from which the radio wave receiving device 14 receives the strongest radio wave. The processor 22 stores the elevator received radio wave strength information in the memory 21 and transmits it to the mobile terminal 3 via the communication circuit 23. The elevator received radio wave strength information may be an elevator received radio wave strength table that indicates, for each floor at which the car 11 stops, two or more wireless communication devices 2 in descending order of the strength of the radio wave received by the radio wave receiving device 14. FIG. 3 is a diagram illustrating the configuration of the mobile terminal 3 according to the first embodiment.

[0019] The mobile terminal 3 includes a memory 31, a processor 32, a touch panel 33, a display 34, and a communication circuit 35.

[0020] The communication circuit 35 can receive radio waves from the wireless communication device 2 and can communicate with the control device 13 .

[0021] The memory 31 stores a program for operating the processor 32, elevator reception signal strength information, and terminal reception signal strength information.

[0022] The processor 32 executes a program stored in the memory 31. The processor 32 receives elevator reception signal strength information from the control device 13 via the communication circuit 35 and stores it in the memory 31. The processor 32 creates terminal reception signal strength information indicating wireless communication devices 2 with strong radio waves received by the communication circuit 35 and stores it in the memory 31. The terminal reception signal strength information may be a terminal reception signal strength list indicating two or more wireless communication devices 2 in descending order of the strength of the radio waves received by the mobile terminal 3. The processor 32 compares the elevator reception signal strength information with the terminal reception signal strength information to determine whether the user is located near the elevator hall. If the processor 32 determines that the user is located near the elevator hall, the processor 32 transmits an elevator call registration signal via the communication circuit 35. The display 34 displays the screen of the elevator linkage application.

[0023] The touch panel 33 accepts inputs by the user such as the boarding floor and the destination floor from the screen of the elevator-linked application.

[0024] FIG. 4 is a flowchart showing the procedure of the elevator call registration method according to the first embodiment.

[0025] In step S101, as a preliminary step, the processor 22 of the control device 13 creates an elevator received signal strength table. The elevator received signal strength table may be updated periodically or when the occupant of a room changes.

[0026] In step S102, the mobile terminal 3 starts an elevator-linked application in accordance with an instruction from the user.

[0027] In step S103, the mobile terminal 3 sets the elevator boarding floor and destination floor on the application screen in accordance with the user's instructions.

[0028] In step S104, the mobile terminal 3 notifies the control device 13 of the start of the elevator linked application.

[0029] In step S105, the processor 22 of the control device 13 receives a notification of the start of the elevator cooperation application.

[0030] In step S106, the processor 22 of the control device 13 transmits the elevator received radio wave intensity table to the mobile terminal 3.

[0031] In step S107, the processor 32 of the mobile terminal 3 receives the elevator received radio wave intensity table.

[0032] In step S108, when the processor 32 of the portable terminal 3 is located near a building in which an elevator for which the boarding floor and the destination floor are set is installed, the processor 32 receives radio waves from multiple wireless communication devices 2 and creates a terminal received radio wave intensity list based on the reception results. The location of the portable terminal 3 can be detected by the GPS of the portable terminal 3.

[0033] In step S109, the processor 32 of the mobile terminal 3 determines whether the user is located near an elevator landing by comparing the elevator reception signal strength table with the terminal reception signal strength list. For example, when two or more wireless communication devices 2 included in the terminal reception signal strength list match, including the order, with two or more wireless communication devices 2 at one stop floor included in the elevator reception signal strength table, the processor 32 of the mobile terminal 3 determines that the user is located near the elevator landing at that stop floor.

[0034] If it is determined in step S110 that the user is located near the elevator hall, the process proceeds to step S111. If it is not determined that the user is located near the elevator hall, the process returns to step S108.

[0035] In step S111, the processor 32 of the mobile terminal 3 transmits to the control device 13 an elevator call registration signal specifying the boarding floor and the destination floor.

[0036] In step S112, the processor 22 of the control device 13 receives an elevator call registration signal.

[0037] In step S113, the processor 22 of the control device 13 controls the movement of the car 11 based on the elevator call registration signal. FIG. 5 is a flowchart showing the detailed processing of step S101. In step S400, the plurality of wireless communication devices 2 start transmitting radio waves.

[0038] In step S401, the processor 22 of the control device 13 stops the elevator car at one floor.

[0039] In step S402, the radio wave receiving device 14 receives radio waves from the plurality of wireless communication devices 2.

[0040] In step S403, the radio wave receiving device 14 notifies the control device 13 of the strength of the radio waves received from the plurality of wireless communication devices 2.

[0041] In step S405, the processor 22 of the control device 13 receives notifications of the strength of radio waves received by the radio wave receiving device 14 from the plurality of wireless communication devices 2.

[0042] In step S406, the processor 22 of the control device 13 creates an elevator received radio wave intensity table based on the intensities of radio waves received by the radio wave receiver 14 from the plurality of wireless communication devices 2. FIG. 6 is a diagram illustrating an elevator received radio wave intensity table according to the first embodiment.

[0043] For example, when the car 11 stops on the first floor, the strength of the radio waves received by the radio wave receiver 14 is, in order from strongest to weakest, the radio communication device in room 103, the radio communication device in room 107, the radio communication device in room 106, etc. When the car 11 stops on the fourth floor, the strength of the radio waves received by the radio wave receiver 14 is, in order from strongest to weakest, the radio communication device in room 401, the radio communication device in room 402, the radio communication device in room 403, etc.

[0044] In step S407, if the elevator car has stopped at all floors, the process ends, and if the elevator car has not stopped at all floors, the process returns to step S401. FIG. 7 is a flowchart showing the detailed processing of step S108. In step S301, the plurality of wireless communication devices 2 start transmitting radio waves.

[0045] In step S302, the processor 32 of the mobile terminal 3 receives radio waves from a plurality of wireless communication devices 2.

[0046] In step S303, the processor 32 of the mobile terminal 3 creates a terminal received radio wave intensity list based on the intensities of radio waves received from the plurality of wireless communication devices 2.

[0047] Fig. 8 is a diagram showing the location of a user at time t1, and Fig. 9 is a diagram showing a terminal received signal strength list created at time t1.

[0048] This is a diagram showing the strength of radio waves received by a user's mobile terminal 3 from multiple wireless communication devices. At time t1, the user is located near room 403 on the fourth floor. The strength of the radio waves received by the mobile terminal 3, in order from strongest to weakest, is the wireless communication device in room 403, the wireless communication device in room 402, the wireless communication device in room 401, etc.

[0049] Fig. 10 is a diagram showing the user's position at time t2, and Fig. 11 is a diagram showing the terminal received signal strength list created at time t2.

[0050] This is a diagram showing the radio waves received by a user's mobile terminal 3 from multiple wireless communication devices in order of strength at time t2. At time t2, the user is located between room 401 on the fourth floor and the elevator landing on the fourth floor. The strength of the radio waves received by mobile terminal 3, in order from strongest to weakest, is the wireless communication device in room 401, the wireless communication device in room 402, the wireless communication device in room 403, and so on.

[0051] As described above, according to this embodiment, it is possible to identify the floor on which an elevator user boards an elevator without installing dedicated equipment at each floor's landing. By adding a radio wave receiving device to equipment installed for maintenance, such as an in-car display, costs can be further reduced. Embodiment 2 FIG. 12 is a diagram illustrating elevator received radio wave intensity information according to the second embodiment.

[0052] The elevator received radio wave intensity information indicates the wireless communication device 2 from which the radio wave receiving device 14 receives the radio wave with the greatest intensity for each floor at which the car 11 stops. FIG. 13 is a diagram illustrating terminal received radio wave intensity information according to the second embodiment.

[0053] The terminal received radio wave intensity information indicates the wireless communication device 2 from which the strength of the radio wave received by the mobile terminal 3 is the greatest.

[0054] The processor 32 of the mobile terminal 3 determines that the user is located near the elevator landing when the wireless communication device 2 included in the terminal reception radio wave intensity information matches the wireless communication device 2 at one of the stopping floors included in the elevator reception radio wave intensity information. Variation 1. The present invention also includes the following modifications. (1) Use in conjunction with a beacon

[0055] At floors where radio waves from the wireless communication device 2 cannot be received, a beacon may be installed at the landing. (2) Wireless communication device

[0056] Although the wireless communication device 2 is installed in each room of the building, it does not have to be installed in every room. Also, the wireless communication device 2 may be installed not in the rooms of the building but in the corridor outside the rooms.
