Abstract
Description
Technical Field
[0001] This disclosure relates to elevator call registration methods and elevator control systems. Background Technology
[0002] For example, International Publication No. 2020 / 188635 describes a method and system for determining the elevator user's departure floor (= departure floor) based on radio waves from beacons installed at the floor level and registering a call to the pre-set destination floor. Summary of the Invention
[0003] However, in the method and system described in Patent Document 1, beacons need to be installed at each floor station in order to determine the floor to be taken. Since installing such specialized equipment as beacons increases costs, the cost of installing the equipment increases with the number of floors.
[0004] Therefore, the purpose of this disclosure is to provide an elevator call registration method and elevator control system that can determine the elevator user's floor without installing dedicated equipment at each floor station.
[0005] The elevator call registration method disclosed herein is an elevator call registration method for elevators equipped with a radio wave receiving device in the elevator car and multiple wireless communication devices in the building where the elevator is located. The method comprises the following steps: the elevator control device generates elevator received radio wave strength information, which indicates the strong radio wave received by the radio wave receiving device for each floor the car stops at; a user's portable terminal generates terminal received radio wave strength information indicating the strong radio wave received by the portable terminal; the portable terminal determines whether the user is close to an elevator floor by comparing the elevator received radio wave strength information with the terminal received radio wave strength information; and if it is determined that the user is close to an elevator floor, the portable terminal sends an elevator call registration signal.
[0006] The elevator control system disclosed herein includes a radio wave receiving device installed in the elevator car, multiple wireless communication devices installed in the building where the elevator is located, an elevator control device, and a portable terminal for the elevator user. The control device generates elevator received radio wave strength information, which represents the strong radio waves received by the radio wave receiving device for each floor the car is stopped at. The portable terminal generates terminal received radio wave strength information, which represents the strong radio waves received by the portable terminal. By comparing the elevator received radio wave strength information with the terminal received radio wave strength information, it is determined whether the user is close to an elevator floor. If it is determined that the user is close to an elevator floor, an elevator call registration signal is sent.
[0007] According to this disclosure, the floor where the elevator user is going can be determined without installing dedicated equipment at each floor station.

[0022] The embodiments will now be described with reference to the accompanying drawings.
[0023] Implementation method 1.
[0024] Figure 1 This is a diagram showing the structure of an elevator system.
[0025] The elevator system includes an elevator 1 installed in the building, wireless communication devices 2 installed in each room of the building, and a portable terminal 3 held by the user of the elevator 1.
[0026] The elevator 1 includes a car 11, a drive unit 12, a control unit 13, and a radio wave receiving unit 14.
[0027] The car 11 moves up and down between multiple floors of the building.

[0029] The control device 13 controls the movement of the car 11. The control device 13 is configured to communicate with the radio wave receiving device 14 and the portable terminal 3.
[0030] A radio wave receiving device 14 is installed in the car 11. The radio wave receiving device 14 is configured 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 as a wireless router or access point, etc.

[0032] The portable terminal 3 receives radio waves from the wireless communication device 2. The portable terminal 3 is configured to communicate with the control device 13 wirelessly.
[0033] Figure 2 This is a diagram showing the structure of the control device 13 in Embodiment 1.
[0034] The control device 13 includes a memory 21, a processor 22, and a communication circuit 23.
[0035] The communication circuit 23 is capable of communicating with the radio wave receiving device 14 and the portable terminal 3.
[0036] The memory 21 stores the program that causes the processor 22 to operate, as well as the information on the intensity of the radio waves received by the elevator.
[0037] Processor 22 executes the program stored in memory 21. Processor 22 generates elevator received radio wave strength information, which represents the wireless communication devices 2 with strong radio waves received by radio wave receiving device 14 at each floor where car 11 stops. Processor 22 stores the elevator received radio wave strength information in memory 21 and transmits it to portable terminal 3 via communication circuit 23. The elevator received radio wave strength information can also be an elevator received radio wave strength table, which represents two or more wireless communication devices 2 in descending order of radio wave strength received by radio wave receiving device 14 at each floor where car 11 stops.
[0038] Figure 3 This is a diagram showing the structure of the portable terminal 3 according to Embodiment 1.
[0039] The portable terminal 3 includes a memory 31, a processor 32, a touch panel 33, a display 34, and a communication circuit 35.
[0040] The communication circuit 35 is capable of receiving radio waves from the wireless communication device 2 and communicating with the control device 13.
[0041] The memory 31 stores the program that causes the processor 32 to operate, the elevator's received radio wave strength information, and the terminal's received radio wave strength information.
[0042] The processor 32 executes the program stored in the memory 31. The processor 32 receives elevator received radio wave strength information from the control device 13 via the communication circuit 35 and stores it in the memory 31. The processor 32 generates terminal received radio wave strength information representing strong radio waves received by the communication circuit 35 and stores it in the memory 31. The terminal received radio wave strength information can also be a terminal received radio wave strength list, which represents two or more wireless communication devices 2 in descending order of the intensity of the radio waves received by the portable terminal 3. The processor 32 determines whether the user is near an elevator landing by comparing the elevator received radio wave strength information with the terminal received radio wave strength information. If the processor 32 determines that the user is near an elevator landing, it sends an elevator call registration signal via the communication circuit 35.
[0043] Display 34 shows the screen of the elevator linkage application.
[0044] The touch panel 33 is based on the user's input of the elevator floor and destination floor from the elevator linkage application screen.
[0045] Figure 4 This is a flowchart illustrating the elevator call registration method of Implementation Method 1.
[0046] In step S101, the processor 22 of the control device 13 generates an elevator received radio wave strength meter as a prior preparation. The elevator received radio wave strength meter can also be updated periodically or when the occupants of the room change.
[0047] In step S102, the portable terminal 3 starts the elevator linkage application according to the user's instructions.
[0048] In step S103, the portable terminal 3 sets the elevator floor and destination floor from the application screen according to the user's instructions.
[0049] In step S104, the portable terminal 3 notifies the control device 13 of the start of the elevator linkage application.
[0050] In step S105, the processor 22 of the control device 13 receives a notification to start the elevator linkage application.
[0051] In step S106, the processor 22 of the control device 13 sends the elevator received radio wave strength meter to the portable terminal 3.
[0052] In step S107, the processor 32 of the portable terminal 3 receives the elevator received radio wave strength meter.
[0053] In step S108, when the processor 32 of the portable terminal 3 is near a building with an elevator that has been set with the boarding and destination floors, it receives radio waves from multiple wireless communication devices 2, and creates a list of received radio wave strengths based on the reception results. The location of the portable terminal 3 can be detected by the GPS of the portable terminal 3.
[0054] In step S109, the processor 32 of the portable terminal 3 determines whether the user is near an elevator floor by comparing the elevator received radio wave strength table with the terminal received radio wave strength list. For example, if the processor 32 of the portable terminal 3 determines that the user is near an elevator floor if the two or more wireless communication devices 2 included in the terminal received radio wave strength list are in the same order as the two or more wireless communication devices 2 of a floor that is stopped in the elevator received radio wave strength table, the processor 32 determines that the user is near an elevator floor that is stopped in the elevator.
[0055] In step S110, if it is determined that the user is in a position close to an elevator floor, the process proceeds to step S111. If it is not determined that the user is in a position close to an elevator floor, the process returns to step S108.
[0056] In step S111, the processor 32 of the portable terminal 3 sends an elevator call registration signal to the control device 13, specifying the elevator floor and the destination floor.
[0057] In step S112, the processor 22 of the control device 13 receives the elevator call registration signal.
[0058] 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.
[0059] Figure 5 This is a flowchart showing the detailed processing of step S101.
[0060] In step S400, the multiple wireless communication devices 2 begin transmitting radio waves.
[0061] In step S401, the processor 22 of the control device 13 stops the elevator car at a floor.
[0062] In step S402, the radio wave receiving device 14 receives radio waves from multiple wireless communication devices 2.
[0063] In step S403, the radio wave receiving device 14 notifies the control device 13 of the strength of the received radio waves from the plurality of wireless communication devices 2.
[0064] In step S405, the processor 22 of the control device 13 receives a notification of the strength of radio waves from multiple wireless communication devices 2, which is received by the radio wave receiving device 14.
[0065] In step S406, the processor 22 of the control device 13 creates an elevator received radio wave strength table based on the strength of the radio waves received by the radio wave receiving device 14 from the multiple wireless communication devices 2.
[0066] Figure 6 This is a graph showing the electromagnetic wave intensity table of the elevator in Implementation Method 1.
[0067] For example, when the elevator car 11 stops at the 1st floor, the radio wave intensity received by the radio wave receiving device 14, from strongest to weakest, is the same as that received by the wireless communication device in room 103, room 107, room 106, and so on. When the elevator car 11 stops at the 4th floor, the radio wave intensity received by the radio wave receiving device 14, from strongest to weakest, is the same as that received by the wireless communication device in room 401, room 402, room 403, and so on.
[0068] In step S407, the process ends if the elevator car stops at all floors; otherwise, the process returns to step S401.
[0069] Figure 7 This is a flowchart showing the detailed processing of step S108.
[0070] In step S301, the multiple wireless communication devices 2 begin transmitting radio waves.
[0071] In step S302, the processor 32 of the portable terminal 3 receives radio waves from multiple wireless communication devices 2.
[0072] In step S303, the processor 32 of the portable terminal 3 creates a list of received radio wave strengths based on the strength of the received radio waves from multiple wireless communication devices 2.
[0073] Figure 8 This is a diagram showing the location of the user at time t1. Figure 9 This is a graph showing the list of received radio wave strengths at time t1.
[0074] This diagram shows the radio waves received by the user's portable terminal 3 from multiple wireless communication devices at time t1, arranged in order of intensity. At time t1, the user is near room 403 on the 4th floor. The radio wave intensities received by the portable terminal 3, from strongest to weakest, are from the wireless communication device in room 403, the wireless communication device in room 402, the wireless communication device in room 401, and so on.
[0075] Figure 10 This is a diagram showing the location of the user at time t2. Figure 11 This is a graph showing the list of received radio wave strengths at time t2.
[0076] This diagram shows the radio waves received by the user's portable terminal 3 from multiple wireless communication devices at time t2, arranged in order of intensity. At time t2, the user is between room 401 on the 4th floor and the 4th floor stop of the elevator. The radio wave intensities received by the portable terminal 3, from strongest to weakest, are from the wireless communication device in room 401, the wireless communication device in room 402, the wireless communication device in room 403, and so on.
[0077] As described above, according to this embodiment, the floor to which the elevator user goes can be determined without installing dedicated equipment at each floor's landing. Costs can be further reduced by adding a radio wave receiving device to maintenance equipment such as an in-car display.
[0078] Implementation method 2.
[0079] Figure 12 This is a diagram showing the electromagnetic wave intensity information received by the elevator in Implementation Method 2.
[0080] The intensity of the received radio waves is represented by the floor where the car 11 stops, and the wireless communication device 2 is the one with the highest intensity of the received radio waves.
[0081] Figure 13 This is a diagram showing the received radio wave intensity information of the terminal in Implementation Method 2.
[0082] The terminal receives radio wave strength information indicating the wireless communication device 2 that receives the strongest radio wave from the portable terminal 3.
[0083] If the wireless communication device 2 included in the received radio wave strength information of the portable terminal 3 is consistent with the wireless communication device 2 of one stop floor included in the received radio wave strength information of the elevator, the processor 32 of the portable terminal 3 determines that the user is in a position close to the elevator floor.
