Description

Technical Field

[0001] The invention relates to an elevator and a control method of the elevator. Background Art

[0002] An operation panel is provided in the elevator car, and passengers register their destination floor by operating buttons on the operation panel. In addition, there are elevators that have a non-contact sensor on the operation panel, and in such elevators, the sensor can register the destination floor by detecting input from the passenger. Furthermore, in the operation panel using the non-contact sensor, a system is provided to prevent passengers from erroneously registering an unexpected destination floor.

[0003] For example, Patent Document 1 states that "it is provided with: a non-contact operating panel, i.e., a car operating panel, having a plurality of sensors for detecting operations for determining a destination layer in a non-contact manner; and a control device for controlling whether to register a destination layer based on detection conditions for detecting the operations. If a destination layer sensor corresponding to the destination layer among the plurality of sensors detects the operation continuously for a first threshold time, the control device registers the destination layer, and further, when the operation is detected continuously for a second threshold time, the control device performs processing for notifying the situation and cancels the registration" (Abstract of Patent Document 1).

[0006] Patent Document 1: Japanese Patent Application Publication No. 2019-142686 Summary of the invention

[0007] Problems to be solved by the invention

[0008] As described above, in the technology described in Patent Document 1, when the operation of the destination floor sensor is detected for the second threshold time, the registration of the destination floor is cancelled in order to prevent the continued detection of a part of the passenger's body, carry-on baggage, etc., which is unexpected by the passenger and erroneous registration (paragraph 0040 of Patent Document 1, etc.). However, for example, when a passenger reaches out his hand to the sensor to register a certain destination floor, and the sensor of the adjacent destination floor also detects the operation, there is a possibility that the detection time does not continue for the second threshold time. In such a case, the registration of the unexpected destination floor of the passenger is not cancelled, and the erroneous registration of the destination floor is maintained.

[0009] The object of the present invention is to provide an elevator and a control method for the elevator, which can improve the convenience of use by canceling the destination floor through the passenger's own operation even if a non-contact sensor makes an erroneous detection.

[0010] Means for solving problems

[0011] In order to solve the above-mentioned problems, the elevator of the present invention comprises: a non-contact sensor, which detects input from passengers; and a display unit, which lights up when the destination floor is registered through the sensor, and when the display unit is lit, if the sensor detects a first given action, the display unit displays a notification of cancellation preparation processing, and if the sensor detects a second given action, the display unit goes out.

[0012] Effects of the Invention

[0013] According to the present invention, an elevator and an elevator control method are provided, and even if a non-contact sensor makes a false detection, the destination floor can be cancelled by the passenger's own operation, thereby improving the convenience of use. In addition, according to the present invention, since the cancellation of the destination floor unexpected by the passenger is also prevented, the convenience of use for the passenger is further improved.

[0037] The following describes the implementation of the present invention by dividing it into Examples 1 to 6.

[0038] Example 1

[0039] Figure 1 This is a block diagram showing the structure of the elevator of Example 1. Although not shown, the elevator of this example includes a car, a counterweight, a main rope, a traction machine, etc. The main rope is driven by the traction machine, and the car and the counterweight are raised and lowered in the hoistway.

[0040] In addition, the car is provided with an operation panel having a contact button 2 and a non-contact sensor 3, a car display 4 such as a liquid crystal display located above the operation panel, and a sound output device 5 such as a speaker. The contact button 2 and the non-contact sensor 3 are controlled by an operation panel control device 6, the car display 4 is controlled by a display control device 7, and the sound output device 5 is controlled by a sound control device 8. The operation panel control device 6, the display control device 7, and the sound control device 8 are connected to the elevator control system 1 by a tail rope or the like. In addition, the contact button 2 has a display portion that lights up when the destination floor is registered.

[0041] Figure 2 2 is a schematic diagram showing the operation panel and the display 4 in the car of this embodiment. Figure 2 As shown in the figure, a non-contact sensor 3 is provided on the right side of the contact button 2 of each destination floor. Although not shown in the figure, the contact button 2 is composed of, for example, a display board with floor numbers printed on it, an electrode plate located on the back side of the display board and having light transmittance, a detection circuit for detecting changes in the electrostatic capacitance of the electrode plate, and a light source for irradiating light to the printed characters when lit. Moreover, when a passenger in the car touches the contact button 2 corresponding to the desired destination floor, the electrostatic capacitance of the electrode plate changes, and the light source irradiates light to the display board, and the contact button 2 is lit, so that the passenger can recognize that the operation of the destination floor has been performed.

[0042] The non-contact sensor 3 uses distance sensors such as TOF (Time of Flight) sensors in addition to photoelectric sensors and electrostatic capacitive sensors. When a passenger covers the non-contact sensor 3 corresponding to the desired destination floor with his hand for a given time, a signal is sent to the contact button 2, and the light source illuminates the button 2. Therefore, the passenger can recognize that the destination floor has been operated, just like when the contact button 2 is touched.

[0043] Next, use Figure 1 The structure of the elevator control system 1 is described below. The elevator control system 1 is placed in a machine room, etc., and controls the speed of the motor of the traction machine, etc. However, in this specification, the description will focus on the part related to the control of the operation panel. Figure 1 As shown, the elevator control system 1 of this embodiment is composed of a transceiver unit 9, a sensor input determination unit 10, a button input determination unit 11, a stop permission determination unit 12, a registration determination unit 13, a destination floor registration unit 14, a button processing unit 15, a display processing unit 16 and a sound processing unit 17.

[0044] The transceiver 9 receives signals from the operation panel control device 6 when the contact button 2 or the non-contact sensor 3 in the car is operated, or sends such operation information from the operation panel and the output information of the elevator (floor position, moving direction, etc.) to the display control device 7 and the sound control device 8. The button input determination unit 11 determines whether there is an input to the contact button 2 based on the signal received by the transceiver 9. The sensor input determination unit 10 determines whether there is an input to the non-contact sensor 3 based on the signal received by the transceiver 9. The stop permission determination unit 12 determines whether to permit a stop at the destination floor with the input when the button input determination unit 11 or the sensor input determination unit 10 determines that there is an input. For example, when a floor where tenants are not staying is input as the destination floor, the stop permission determination unit 12 regards the destination floor as unavailable for service and does not permit the stop. When the stop permission determination unit 12 does not permit the stop, the display processing unit 16 sends a signal to the display control device 7 via the transceiver unit 9, and displays the meaning that it cannot be registered as the destination floor on the display 4 in the car. The sound processing unit 17 sends a signal to the sound control device 8 via the transceiver unit 9, and broadcasts the meaning that it cannot be registered as the destination floor using the sound output device 5.

[0045] The registration determination unit 13 determines whether the destination floor for which the stop permission determination unit 12 permits the vehicle to stop has been registered. The destination floor registration unit 14 performs a new registration process when the input destination floor is not registered, and performs a cancellation process when the input destination floor has been registered. When performing the registration or cancellation process, the destination floor registration unit 14 sends a signal to the display processing unit 16, the sound processing unit 17, and the button processing unit 15 to inform the passengers in the car.

[0046] The button processing unit 15 includes a lighting processing unit 15a, a flashing processing unit 15b, and a flashing processing unit 15c. When the destination layer is registered, the lighting processing unit 15a sends a signal to the operation panel control device 6 via the transceiver 9 to light up the touch button 2. When the destination layer is cancelled, the flashing processing unit 15c sends a signal to the operation panel control device 6 via the transceiver 9 to turn off the touch button 2. The flashing processing unit 15b temporarily flashes the touch button 2 from the time when the destination layer is input to the completion of the registration or cancellation process.

[0047] Figure 3 As an example, the figure shows a state where the hand covers the non-contact sensor 3 on the right side of the contact button 2 on the third floor, and the contact button 2 on the third floor flashes temporarily. In this embodiment, even if there is an input to the non-contact sensor 3 for an unregistered destination floor, it is not registered immediately, but is set until the input time reaches the first given time. Figure 3 The flashing state shown can suppress the erroneous registration by the passenger through unconscious momentary input. Even if there is an input from the non-contact sensor 3 for the destination floor where the registration is completed, it is not cancelled immediately, but is also set to a temporary flashing state, thereby suppressing the unconscious cancellation of the passenger.

[0048] Figure 4 As an example, the diagram shows a state in which the input time to the non-contact sensor 3 reaches the first predetermined time, the third floor is registered as the destination floor, and the contact button 2 of the third floor is lit. Figure 5 This figure shows a situation where the third floor is registered as the destination floor and the contact button 2 of the third floor remains lit even if the passenger stops covering the non-contact sensor 3 with his hand. In this way, when the passenger covers the non-contact sensor 3 with his hand, the contact button 2 is lit in the same manner as when the contact button 2 is touched, so there is no need to provide a separate structure such as a light source for the non-contact sensor 3.

[0049] Figure 6This is a flowchart showing the processing of registering and canceling a destination floor by the non-contact sensor 3 of the elevator in Example 1. First, the sensor input determination unit 10 of the elevator control system 1 determines whether the non-contact sensor 3 of a certain destination floor detects an input (step S101). When the input of the non-contact sensor 3 is not detected, the on / off state of the contact button 2 is maintained as it is. Next, when the input of the non-contact sensor 3 is detected, the stop permission determination unit 12 determines whether the destination floor with the input can be served (step S102). When the destination floor with the input cannot be served, the off state of the contact button 2 is maintained as it is, and the passengers are informed that the destination floor cannot be stopped through the in-car display 4 and the sound output device 5. When the destination floor with the input can be served, the registration determination unit 13 determines whether the destination floor is not registered (step S103).

[0050] When the destination layer is not registered, the destination layer registration unit 14 determines whether the input time to the non-contact sensor 3 has reached the first given time (step S104). Until the input time reaches the first given time, the button processing unit 15 flashes the contact button 2 corresponding to the destination layer (step S105). Then, if the input time reaches the first given time, the destination layer registration unit 14 registers the destination layer (step S106), and the button processing unit 15 changes the contact button 2 corresponding to the destination layer from the flashing state to the lit state (step S107). In addition, when the input is no longer detected before the input time reaches the first given time, the button processing unit 15 changes the contact button 2 corresponding to the destination layer from the flashing state to the extinguished state.

[0051] In addition, step S102 may not be present, or a maintenance and repair mode may be set and skipped in this maintenance and repair mode, and the process proceeds to the lighting / flashing / extinguishing action of the contact button 2 regardless of the presence or absence of a stop floor. The maintenance and repair mode can be switched, for example, when the maintenance switch in the car is turned on, or a maintenance command is input to the elevator control system 1 so that the authentication / matching of the above command is established. Methods for releasing this mode include the case where the maintenance switch in the car is turned off, or the maintenance command is input again to the elevator control system 1 so that the authentication / matching of the above command is established. In the maintenance and repair mode, it is also possible to have a structure that does not accept call registrations from the sensor but only confirms the working status of the non-contact sensor 3 and the flashing status of the contact button 2. It is also possible to have the following structure: in this mode, the call registration from the sensor is ignored. Figure 6The steps S103 to S111 described above simply determine whether the input of the non-contact sensor 3 is possible, and flash when the input is detected, and turn off when it is not detected. In addition, in the absence of this step, when the non-contact sensor 3 of a layer other than the stop layer is operated, the contact button 2 flashes until a given time, and when the given time has passed, a guidance indicating that the service on that layer cannot be provided is provided. For example, a voice guidance indicating that the service on that layer cannot be provided can be provided.

[0052] Figure 7 This is a diagram showing the transition from registering the destination floor by inputting a given (for example, the third floor) non-contact sensor 3 to lighting up the touch button 2 in Example 1. In this way, by flashing the touch button 2 until the input time reaches the first given time and the touch button lights up, the passenger can recognize that the non-contact sensor 3 is responding, thereby improving the convenience of use.

[0053] On the other hand, when the destination layer is registered, the destination layer registration unit 14 determines whether the input time to the non-contact sensor 3 has reached the first given time (step S108). Until the input time reaches the first given time, the button processing unit 15 flashes the contact button 2 corresponding to the destination layer (step S109). Moreover, if the input time reaches the first given time, the destination layer registration unit 14 cancels the destination layer (step S110), and the button processing unit 15 changes the contact button 2 corresponding to the destination layer from the flashing state to the extinguished state (step S111). In addition, when no input is detected before the input time reaches the first given time, the button processing unit 15 changes the contact button 2 corresponding to the destination layer from the flashing state to the lit state.

[0054] According to this embodiment, since the input time to the non-contact sensor 3 is registered only when it reaches the first given time, it is possible to suppress unexpected registration by passengers. Even if the non-contact sensor 3 performs false detection and registration, the destination floor can be canceled by the passenger's own operation, and the convenience of using the elevator is improved. In addition, since the threshold value of the input time to the non-contact sensor 3 is set to the common first given time when registering and canceling, it is easy for passengers to understand the operation. However, in the case of wanting to perform a registration operation with high frequency of use in a short time, the threshold value of the input time when registering can also be made shorter than that when canceling.

[0055] Example 2

[0056] Figure 81 is a block diagram showing the structure of the elevator of the second embodiment. In the elevator of the first embodiment, the lighting / flashing of the touch button 2 is entirely controlled by the button processing unit 15 of the elevator control system 1, but in the elevator of the second embodiment, the non-contact sensor 3 also has the function of controlling the lighting / flashing of the touch button 2. Figure 8 As shown, in this embodiment, unlike the embodiment 1, the elevator control system 1 does not have a sensor input determination unit 10, and the non-contact sensor 3 has a lighting processing unit (non-contact sensor) 3a, a flashing processing unit (non-contact sensor) 3b and a extinguishing processing unit (non-contact sensor) 3c.

[0057] Fig. 9 This is a diagram showing the transition from registering the destination floor by inputting a given (for example, the third floor) non-contact sensor 3 in the second embodiment to lighting up the touch button 2. When the non-contact sensor 3 of the present embodiment detects an input, first, the flashing processing unit (non-contact sensor) 3b flashes the touch button 2, and when the input time reaches a first given time, the lighting processing unit (non-contact sensor) 3a lights up the touch button 2 (see FIG. 1 ). Fig. 9 A). The non-contact sensor 3 lights up the contact button 2 and sends a signal sent when the contact button 2 is input to the elevator control system 1, replacing the contact button 2 (refer to Fig. 9 Then, the elevator control system 1 that receives the signal from the non-contact sensor 3 registers the destination floor using the destination floor registration unit 14. At this time, the button processing unit 15 of the elevator control system 1 sends a lighting instruction signal to the contact button 2 (refer to Fig. 9 C), but since the contact button 2 is lit by the non-contact sensor 3, the lighting state of the contact button 2 is maintained.

[0058] In addition, when the destination floor is cancelled by the input of the non-contact sensor 3, if the input time reaches the first given time, the extinguishing processing unit (non-contact sensor) 3c turns off the touch button 2, and transmits the signal sent when the touch button 2 is cancelled to the elevator control system 1 through the non-contact sensor 3. The signal at this time is the same as the cancellation (long press) when the touch button 2 is touched for a given time (for example, 1 second) or more.

[0059] Fig.10 This is a flowchart showing the process of registering and canceling a destination floor by the non-contact sensor 3 of the elevator according to the second embodiment.

[0060] First, the non-contact sensor 3 corresponding to each destination layer determines whether each destination layer can be served based on the signal received from the stop permission determination unit 12 of the elevator control system 1 (step S201). If the destination layer cannot be served, registration of the destination layer is not permitted, and the contact button 2 remains off. If the destination layer can be served, the non-contact sensor 3 determines whether input is detected (step S202). If no input is detected, the on / off state of the contact button 2 is maintained unchanged. If input is detected, the non-contact sensor 3 determines whether the destination layer is unregistered based on the signal received from the registration determination unit 13 of the elevator control system 1 (step S203).

[0061] When the destination floor is not registered, the non-contact sensor 3 determines whether the input time has reached the first given time (step S204). Until the input time reaches the first given time, the flashing processing unit (non-contact sensor) 3b flashes the contact button 2 corresponding to the destination floor (step S205). Then, if the input time reaches the first given time, the lighting processing unit (non-contact sensor) 3a lights up the contact button 2 corresponding to the destination floor (step S206). At this time, the non-contact sensor 3 sends a signal to the elevator control system 1, and the destination floor registration unit 14 registers the destination floor (step S207).

[0062] On the other hand, when the destination floor registration is completed, the non-contact sensor 3 determines whether the input time to the non-contact sensor 3 has reached the first given time (step S208). Until the input time reaches the first given time, the flashing processing unit (non-contact sensor) 3b flashes the contact button 2 corresponding to the destination floor (step S209). Then, if the input time reaches the first given time, the extinguishing processing unit (non-contact sensor) 3c extinguishes the contact button 2 corresponding to the destination floor (step S210). At this time, the non-contact sensor 3 sends a signal to the elevator control system 1, and the destination floor registration unit 14 cancels the destination floor (step S211).

[0063] Example 3

[0064] Fig.11This is a flowchart showing the processing of registering and canceling the destination floor by the non-contact sensor 3 of the elevator in the third embodiment. In the elevator involved in the second embodiment, when the destination floor registration is completed, if the input time to the non-contact sensor 3 reaches the first given time, the touch button 2 is immediately turned off to cancel the destination floor. However, in the elevator involved in the third embodiment, even if the input time to the non-contact sensor 3 reaches the first given time, it is not immediately canceled, but the touch button 2 changes from the flashing state to the second flashing state (step S310), and transfers to the cancellation preparation (step S311).

[0065] Fig.12 Yes means Fig.11 Flowchart of the processing performed by the non-contact sensor 3 after the cancellation preparation is transferred to the destination layer. First, the non-contact sensor 3 corresponding to each destination layer determines whether it is a destination layer in the cancellation preparation (step S312). In the case of the destination layer in the cancellation preparation, it is determined whether the elapsed time from the transfer to the cancellation preparation reaches the third given time (step S313). In the case that the elapsed time from the transfer to the cancellation preparation has reached the third given time, the contact button 2 of the destination layer is restored to the lighting state (step S314), and the cancellation preparation is released (step S315).

[0066] Before the elapsed time from the transition to the cancellation preparation reaches the third given time, it is determined whether the non-contact sensor 3 detects input again (step S316). Here, during the period when no input is detected again, or during the period when the input is continuously detected from the transition to the cancellation preparation, the second flashing state of the contact button 2 is maintained (step S317). On the other hand, in the case where the non-contact sensor 3 detects input again, it is determined whether the input time has reached the second given time (step S318). Until the input time reaches the second given time, the flashing processing unit (non-contact sensor) 3b flashes the contact button 2 corresponding to the destination layer (step S319). Then, if the input time reaches the second given time, the extinguishing processing unit (non-contact sensor) 3c extinguishes the contact button 2 corresponding to the destination layer (step S320). At this time, the non-contact sensor 3 sends a signal to the elevator control system, and the destination layer registration unit 14 cancels the destination layer (step S321).

[0067] Fig.13 1 is a diagram showing the transition from canceling the destination floor by inputting a given (for example, 3 floors) non-contact sensor 3 to turning off the contact button 2 in the third embodiment. Fig.13As shown in FIG. 1 , the flash processing unit (non-contact sensor) 3 b of the present embodiment sets the contact button 2 to the first flashing state when input is detected, sets the contact button 2 to the second flashing state when the input time reaches the first given time, and sets the contact button 2 to the first flashing state when another input is detected (see FIG. 1 ). Fig.13 A). Then, if the input reaches the second given time, the extinguishing processing unit (non-contact sensor) 3c turns off the contact button 2. The non-contact sensor 3 turns off the contact button 2 and sends the signal sent when the contact button 2 is cancelled to the elevator control system 1, replacing the contact button 2 (refer to Fig.13 Here, the same signal as the cancellation signal when the contact button 2 is touched twice in succession (pressed twice) is sent, for example, a signal that turns on the current for a few ms and turns on the current for a few ms again within 1 second. Then, the elevator control system 1 that receives the signal from the non-contact sensor 3 cancels the destination floor through the destination floor registration unit 14. At this time, the button processing unit 15 of the elevator control system 1 sends a command signal to turn off the contact button 2 (refer to Fig.13 C), but the contact button 2 is turned off by the non-contact sensor 3, so the turned-off state of the contact button 2 is maintained.

[0068] In this embodiment, the cancellation is not immediately made upon input of the first predetermined time, but is actually made when the passenger once removes his hand from the non-contact sensor 3 and then approaches the sensor again after the cancellation preparation is entered, thereby suppressing the passenger's unconscious cancellation. Fig.13 As shown in FIG. 1 , when the state is shifted to the cancel preparation state, the state changes to a second flashing state (second flashing state) different from the previous normal flashing state (first flashing state), so that the passenger can recognize that the state is in the cancel preparation state. Furthermore, when the non-contact sensor 3 detects input again during the cancel preparation state, the state changes to the normal flashing state, so that the passenger can also recognize that the operation of bringing the hand close again has responded.

[0069] Here, in this embodiment, the second flashing state is set to flash with a longer lighting time compared to the first flashing state, but any flashing can be used as long as it is different from the lighting method of the first flashing state and is easy for passengers to distinguish. In addition, since the contact button 2 also becomes a flashing state when the car arrives at the destination floor, the first lighting state and the second lighting state become flashing methods that are different from the arrival (for example, flashing with a shorter lighting time than the arrival).

[0070] Furthermore, the second given time, which is the threshold value of the input time for transitioning from preparation for cancellation to cancellation, is made the same as the first given time, which is the threshold value of the input time for transitioning to registration and preparation for cancellation, so that the operation is easier for passengers to understand, but they may be different.

[0071] [Variation of Embodiment 3]

[0072] Fig.14 This is shown as a variation of Example 3. Fig.11 After the cancellation preparation is transferred to the destination layer Fig.12 Different processing flow chart. In this modification, unlike in the third embodiment, even if the non-contact sensor 3 detects another input after the transition to the cancellation preparation, the contact button 2 maintains the second flashing state (step S317'). Thereafter, if the input time reaches the second given time, the contact button 2 turns off (step S320) and the destination layer is canceled (step S321) in the same manner as in the third embodiment.

[0073] Fig.15 1 is a diagram showing the transition from canceling the destination floor by inputting a given number of floors (for example, the third floor) to turning off the contact button 2 in a modification of the third embodiment. Fig.15 As shown, when the state shifts to the cancel preparation, the state changes to the second blinking state as in the third embodiment. However, when the proximity sensor 3 detects input again during the cancel preparation, the second blinking state is maintained in the present modification.

[0074] In addition, if the non-contact sensor 3 detects another input after the transition to the cancellation preparation, but the elapsed time after the transition to the cancellation preparation reaches the third predetermined time before the input time reaches the second predetermined time, the cancellation preparation is canceled and the state remains unchanged. Fig.11 In this case, in the present modification, since the contact button 2 changes from the second blinking state to the normal blinking state, the passenger can recognize that the cancellation preparation is released.

[0075] Example 4

[0076] Embodiment 4 switches the mode related to registration / cancellation of the destination layer through the operation panel. Fig.16 This is a flowchart showing the mode switching process of the fourth embodiment.

[0077] First, the non-contact sensor 3 determines whether it is operating normally (step S401). If the non-contact sensor 3 is not operating normally due to a computer failure or the like, the mode is switched to a button-only mode that accepts only registration / cancellation through the contact button 2 (step S402). If the non-contact sensor 3 is operating normally, the non-contact sensor 3 is determined to be usable (step S403). If the use of the non-contact sensor 3 is not permitted due to the wishes of the elevator manager or the like, the mode is switched to a button-only mode (step S402).

[0078] On the other hand, when the use of the non-contact sensor 3 is permitted, the mode is switched to a sensor operation mode (step S404) in which the destination layer can be registered / cancelled by both the non-contact sensor 3 and the contact button 2. Here, the sensor operation mode of the present embodiment can select a sensor priority mode that gives priority to the convenience of use of the non-contact sensor 3 and a button priority mode that gives priority to the convenience of use of the contact button 2 (step S405).

[0079] When the sensor priority mode is selected (step S406), the first given time and the second given time are set to be as long as 0.5s to 1s, and the third given time is set to be as long as 2s to 3s. In this case, since the passenger must continue to touch the button for 0.5 to 1s when registering with the contact button 2, etc., although the operability of the contact button 2 is reduced, the input time until the registration with the non-contact sensor 3 is fully ensured, so the false detection of the non-contact sensor 3 is suppressed. On the other hand, when the button priority mode is selected (step S407), for example, the first given time and the second given time are set to be as short as 0ms to several milliseconds, and the third given time is set to be as short as 1s. In this case, since the non-contact sensor 3 is also registered after covering only 0ms to several milliseconds, although the possibility of false detection by the non-contact sensor 3 is increased, the operability of the contact button 2 is improved.

[0080] Example 5

[0081] Fig.17 This is a block diagram showing the structure of an elevator according to Embodiment 5. In the elevator according to Embodiment 5, a capacitive Braille touch detection device 18 is connected to the non-contact sensor 3, for example, and while the Braille sign is being touched, input via the non-contact sensor 3 is cut off, and registration / cancellation of the destination floor is no longer possible.

[0082] Fig.18 2 is a schematic diagram showing the operation panel and the display 4 in the car of this embodiment. Fig.18As shown, a Braille sign 19 is provided on the left side of the contact button 2 of each destination floor, and a Braille touch detection device 18 (not shown) detects that a passenger touches the Braille sign 19 .

[0083] Fig.19 1 is a flowchart showing the registration and cancellation of the destination floor by the non-contact sensor 3 of the elevator in Example 5. First, the Braille contact detection device 18 determines whether there is no contact with the Braille sign 19 (step S501). In the case where there is no contact with the Braille sign 19, it is determined whether the elapsed time since the Braille contact disappears has reached the fourth given time (step S502). Since the passenger who touches the Braille sign 19 has the possibility of operating the contact button 2 until the fourth given time is reached, the input of the non-contact sensor 3 is cut off (step S503). In addition, in the case of contact with the Braille sign 19, the elapsed time of the non-contact of the Braille sign is reset (step S504), and the input to the non-contact sensor 3 is immediately cut off (step S503). If the elapsed time of the non-contact of the Braille sign reaches the fourth given time, the non-contact sensor 3 corresponding to each destination floor becomes to receive input, and the same operation as step S302 of Example 3 (reference) is performed. Fig.11 )The same process will be applied later.

[0084] According to this embodiment, it is possible to prevent the non-contact sensor 3 from being misoperated by passengers who need Braille, and to realize an elevator with good usability. In addition, in this embodiment, when the Braille contact detection device 18 detects contact with the Braille sign 19, the input of all non-contact sensors 3 is cut off. However, it is also possible that the Braille contact detection device 18 detects contact with the Braille sign 19 of a destination floor, and only the input of the non-contact sensor 3 corresponding to the destination floor that has been touched is cut off.

[0085] Example 6

[0086] Fig. 20 is a block diagram showing the structure of an elevator according to Embodiment 6. Fig.21 1 is a schematic diagram showing an operation panel and an in-car display according to Embodiment 6. In the elevator according to Embodiment 6, a camera is provided on the in-car display as a human motion detection device 20, and the human motion detection device 20 (camera) is connected to the operation panel control device 6.

[0087] The image data captured by the camera is processed by the OpenPose method, for example, and when the passenger's hand-covering action is detected, the destination floor can be registered and cancelled by the non-contact sensor 3. In addition, when a camera equipped with a distance image sensor such as a TOF sensor is used as the human motion detection device 20, the distance and direction of the passenger can also be measured. When the measurement result satisfies a given condition, the destination floor can be registered by the non-contact sensor 3. For example, when the operation panel is within a given angle range relative to the position vector of the face extending in the vertical direction from the center of the position of the two eyes (two shoulders) or the nose (reference Fig. 22 ), it is determined that the passenger is heading towards the operating panel. Furthermore, when the passenger and the operating panel are within a given distance range, it is determined that the passenger is about to operate the operating panel.

[0088] Fig.23 Flow chart showing the process of registering and canceling the destination floor by the non-contact sensor 3 of the elevator in Embodiment 6. In this embodiment, since the human motion detection device 20 is provided to detect the presence or absence of the passenger operating the operation panel (step S605), it is possible to more accurately determine whether the input of the non-contact sensor 3 is the input expected by the passenger, and further suppress the erroneous registration and erroneous cancellation of the destination floor. In addition, in this embodiment, an example of using a camera as the human motion detection device 20 is described, but in addition to the camera, a photoelectric sensor or an electrostatic capacitance sensor may also be used.

[0089] The above is divided into Examples 1 to 6 to explain the implementation of the present invention, but the present invention is not limited to Examples 1 to 6 and includes various modifications. In addition, a part of the structure of a certain embodiment can be replaced with the structure of another embodiment, and the structure of another embodiment can be added to the structure of a certain embodiment. In addition, other structures can be added, deleted, or replaced with a part of the structure of each embodiment.
