To achieve this, the elevator according to the present invention comprises a non-contact sensor that detects input from a passenger and a display unit that lights up when a destination floor is registered by the sensor. When the sensor detects a first predetermined operation while the display unit is lit, the display unit displays a notification of cancellation preparation processing, and when the sensor detects a second predetermined operation, the display unit turns off.

Description

Elevator and elevator control method

The present invention relates to an elevator and an elevator control method.

An operation panel is provided in the elevator car, and passengers register the destination floor by operating the buttons on the operation panel. There is also an elevator having a non-contact type sensor on the operation panel, and in such an elevator, it is possible to register the destination floor by detecting the input from the passenger. In the operation panel using the non-contact type sensor, measures are taken to prevent erroneous registration of the destination floor unintentional by the passenger.

For example, Patent Document 1 describes "a car operation panel which is a non-contact operation panel having a plurality of sensors for non-contactly detecting an operation for determining a destination floor, and a detection condition for detecting the operation. , A control device for controlling whether or not to register the destination floor. In the control device, the destination floor sensor corresponding to the destination floor among a plurality of sensors continuously detects the operation until the first threshold time. Then, when the destination floor is registered and the operation is continuously detected until the second threshold time, a process for notifying the operation is executed and the registration is canceled "(Patent Document 1). wrap up).

Japanese Unexamined Patent Publication No. 2019-142686

As described above, the technique described in Patent Document 1 continues to detect a part of the passenger's body or baggage when the operation of the destination floor sensor is continuously detected until the second threshold time. Is intended to cancel the registration of the destination floor in order to prevent unintentional erroneous registration (paragraph 0040 of Patent Document 1, etc.). However, for example, when a passenger reaches for the sensor to register a destination floor and the sensor on the adjacent destination floor also detects the operation, the detection time is the second threshold time. It may not continue until. In such a case, the registration of the destination floor not intended by the passenger is not canceled, and the erroneous registration of the destination floor is maintained.

An object of the present invention is to provide an elevator and an elevator control method that can cancel the destination floor by the passenger's own operation even if the non-contact type sensor erroneously detects the elevator and the elevator with improved usability.

In order to solve the above problems, the present invention relates to an elevator provided with a non-contact type sensor that detects an input from a passenger and a display unit that lights up when the destination floor is registered by the sensor. The display unit displays a display notifying the preparation process for cancellation when the sensor detects the first predetermined operation while the display unit is lit, and turns off the display unit when the sensor detects the second predetermined operation.

According to the present invention, even if a non-contact type sensor erroneously detects an elevator, the destination floor can be canceled by the passenger's own operation, and it is possible to provide an elevator and an elevator control method with improved usability. Further, according to the present invention, cancellation of the destination floor unintentionally by the passenger is prevented, so that the usability of the passenger is further improved.

Hereinafter, embodiments of the present invention will be described separately in Examples 1 to 6.

FIG. 1 is a block diagram showing the configuration of the elevator of the first embodiment. Although not shown, the elevator of this embodiment is equipped with a car, a balance weight, a main rope, a hoist, and the like, and the hoist drives the main rope to drive the car and the balance weight. Is designed to go up and down in the hoistway.

Further, the car has an operation panel equipped with a contact type button 2 and a non-contact type sensor 3, an in-car display 4 such as a liquid crystal display at the upper part of the operation panel, and a sound output device 5 such as a speaker. Is provided. The contact type button 2 and the non-contact type sensor 3 are controlled by the operation panel control device 6, the in-car display 4 is controlled by the display control device 7, and the sound output device 5 is controlled by the sound control device 8. Further, 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 code or the like. The contact button 2 has a display unit that lights up when the destination floor is registered.

FIG. 2 is a schematic view showing an operation panel and an in-car display 4 of this embodiment. As shown in FIG. 2, a non-contact sensor 3 is provided on the right side of the contact button 2 on each destination floor. Although not shown, the contact type button 2 detects, for example, a display sheet on which a number on the floor is printed, an electrode plate having translucency on the back side of the display sheet, and a change in the capacitance of the electrode plate. It is composed of a detection circuit that illuminates the print and a light source that illuminates the print when it is lit. Then, when a passenger in the car touches the contact type button 2 corresponding to the desired destination floor, the capacitance of the electrode plate changes, and the light source irradiates the display sheet with light, so that the contact type button 2 lights up. Therefore, the passenger can recognize that the operation of the destination floor has been performed.

As the non-contact type sensor 3, for example, a distance sensor such as a TOF (Time of Flight) sensor is used in addition to a photoelectric sensor and a capacitance sensor. When the passenger holds his / her hand over the non-contact sensor 3 corresponding to the desired destination floor for a predetermined time, a signal is sent to the contact button 2 and the light source irradiates light to light up, so that the passenger touches the contact button 2. As in the case, the passenger can recognize that the operation of the destination floor has been performed.

Next, the configuration of the elevator control system 1 will be described with reference to FIG. The elevator control system 1 is placed in a machine room or the like and controls the speed of the motor of the hoist, etc., but in this specification, the part related to the control of the operation panel will be mainly described. As shown in FIG. 1, the elevator control system 1 of this embodiment has a transmission / reception 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, and a destination. It is composed of a floor registration unit 14, a button processing unit 15, a display processing unit 16, and a sound processing unit 17.

The transmission / reception unit 9 receives a signal from the operation panel control device 6 when the contact type button 2 or the non-contact type sensor 3 in the car is operated, and the operation information from the operation panel or the output information of the elevator ( The floor position, movement direction, etc.) are transmitted to the display control device 7 and the sound control device 8. The button input determination unit 11 determines whether or not there is an input to the contact type button 2 based on the signal received by the transmission / reception unit 9. The sensor input determination unit 10 determines whether or not there is an input to the non-contact type sensor 3 based on the signal received by the transmission / reception unit 9. When the button input determination unit 11 or the sensor input determination unit 10 determines that there is an input, the stop permission determination unit 12 determines whether or not the stop at the destination floor where the input is made is permitted. For example, when a floor without a tenant is input as a destination floor, the stop permission determination unit 12 does not allow the stop because the destination floor cannot be serviced. When the stop permission determination unit 12 does not permit the stop, the display processing unit 16 transmits a signal to the display control device 7 via the transmission / reception unit 9 and displays on the car display 4 that it cannot be registered as the destination floor. Then, the sound processing unit 17 transmits a signal to the sound control device 8 via the transmission / reception unit 9, and the sound output device 5 announces that the signal cannot be registered as the destination floor.

The registration determination unit 13 determines whether or not the destination floor for which the stop permission determination unit 12 has been permitted to stop has already been registered. The destination floor registration unit 14 performs a new registration process when the input destination floor is not registered, and cancels the input destination floor when the input destination floor is registered. When the registration or cancellation process is performed, the destination floor registration unit 14 transmits a signal to the display processing unit 16, the sound processing unit 17, and the button processing unit 15 to notify the passengers in the car.

The button processing unit 15 has a lighting processing unit 15a, a blinking processing unit 15b, and a light-off processing unit 15c. When the destination floor is registered, the lighting processing unit 15a transmits a signal to the operation panel control device 6 via the transmission / reception unit 9 to light the contact type button 2. When the destination floor is canceled, the turn-off processing unit 15c transmits a signal to the operation panel control device 6 via the transmission / reception unit 9 to turn off the contact-type button 2. The blinking processing unit 15b temporarily blinks the contact type button 2 from the time when the input to the destination floor is received until the processing of registration or cancellation is completed.

FIG. 3 is a diagram showing, as an example, a state in which a hand is held over 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 is tentatively blinking. .. In this embodiment, even if there is an input from the non-contact sensor 3 for an unregistered destination floor, the non-contact sensor 3 is not immediately registered, and the blinking state is set as shown in FIG. 3 until the input time reaches the first predetermined time. As a result, it is possible to suppress erroneous registration due to momentary input without the intention of the passenger. Even if there is an input from the non-contact sensor 3 for the registered destination floor, it is not canceled immediately, but is similarly provisionally blinked, so that cancellation without the intention of the passenger is suppressed.

FIG. 4 is a diagram showing, as an example, 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 on the third floor is lit. FIG. 5 is a diagram showing that the third floor is registered as the destination floor, and the contact button 2 on the third floor remains lit even when the non-contact sensor 3 is stopped from being held. In this way, even when the passenger holds his / her hand over the non-contact sensor 3, the contact button 2 lights up in the same manner as when the passenger touches the contact button 2. Therefore, a light source or the like for the non-contact sensor 3 is used. There is no need to provide a separate configuration.

FIG. 6 is a flowchart showing the processing of registration and cancellation of the destination floor by the non-contact sensor 3 of the elevator of the first embodiment. First, the sensor input determination unit 10 of the elevator control system 1 determines whether or not the non-contact sensor 3 on a certain destination floor has detected an input (step S101). When the input of the non-contact sensor 3 is not detected, the lighting / extinguishing state of the contact button 2 is maintained as it is. Next, when the input of the non-contact type sensor 3 is detected, the stop permission determination unit 12 determines whether or not the destination floor to which the input has been input can be serviced (step S102). If the service is not available on the destination floor where the input was made, the contact type button 2 is kept off as it is, and the passenger is notified by the car display 4 and the sound output device 5 that the destination floor cannot be stopped. do. If the input destination floor is serviceable, the registration determination unit 13 determines whether or not the destination floor is unregistered (step S103).

When the destination floor is not registered, the destination floor registration unit 14 determines whether or not the input time to the non-contact sensor 3 has reached the first predetermined time (step S104). Until the input time reaches the first predetermined time, the button processing unit 15 blinks the contact type button 2 corresponding to the destination floor (step S105). Then, when the input time reaches the first predetermined time, the destination floor registration unit 14 registers the destination floor (step S106), and the button processing unit 15 blinks the contact type button 2 corresponding to the destination floor. To change to the lighting state (step S107). If the input is not detected before the input time reaches the first predetermined time, the button processing unit 15 changes the contact type button 2 corresponding to the destination floor from the blinking state to the extinguished state.

It should be noted that step S102 may be omitted, or the maintenance / inspection mode may be provided, and the step may be skipped in the maintenance / inspection mode, and the contact type button 2 may be lit / blinked regardless of the presence or absence of the stop floor. You may proceed to the / turn-off operation. The maintenance / inspection mode can be switched, for example, when the maintenance switch in the car is turned on, or when a maintenance command is input to the elevator control system 1 and the authentication / verification of the above command is established. The method of canceling the mode includes the case where the maintenance switch in the car is turned off, the case where the maintenance command is input again to the elevator control system 1 and the authentication / verification of the above command is established, and the like. Be done. In the maintenance / inspection mode, the call registration from the sensor may not be accepted, and the configuration may be such that only the operating status of the non-contact sensor 3 and the blinking state of the contact button 2 are confirmed. In this mode, steps S103 to S111 shown in FIG. 6 may be ignored, and it may be possible to simply determine whether or not the non-contact sensor 3 can be input, blink when the input is detected, and turn off the light when the input is not detected. If there is no such step, if the non-contact sensor 3 on the floor that was not the stop floor is operated, the contact button 2 blinks until a predetermined time, and after the predetermined time elapses, the service cannot be performed on the floor. Guidance to that effect is executed. For example, there is voice guidance such as not being available on that floor.

FIG. 7 is a diagram showing the transition from the registration of the destination floor to the lighting of the contact type button 2 by the input to the predetermined (as an example, the third floor) non-contact type sensor 3 in the first embodiment. In this way, by blinking the contact type button 2 until the input time reaches the first predetermined time and the contact type button is turned on, the passenger can recognize that the non-contact type sensor 3 is reacting. Usability is improved.

On the other hand, when the destination floor has been registered, the destination floor registration unit 14 determines whether or not the input time to the non-contact sensor 3 has reached the first predetermined time (step S108). Until the input time reaches the first predetermined time, the button processing unit 15 blinks the contact type button 2 corresponding to the destination floor (step S109). Then, when the input time reaches the first predetermined time, the destination floor registration unit 14 cancels the destination floor (step S110), and the button processing unit 15 blinks the contact type button 2 corresponding to the destination floor. Is changed to the off state (step S111). If the input is not detected before the input time reaches the first predetermined time, the button processing unit 15 changes the contact type button 2 corresponding to the destination floor from the blinking state to the lit state.

According to this embodiment, since the registration is performed only when the input time to the non-contact sensor 3 reaches the first predetermined time, the unintended registration of the passenger can be suppressed. Even if the non-contact sensor 3 erroneously detects and registers, the destination floor can be canceled by the passenger's own operation, and the usability of the elevator is improved. Further, since the threshold value of the input time to the non-contact sensor 3 is set to the first predetermined time common between the registration time and the cancellation time, the operation is easy for the passenger to understand. However, if it is desired to perform the frequently used registration operation in a short time, the threshold value of the input time at the time of registration may be shorter than that at the time of cancellation.

FIG. 8 is a block diagram showing the configuration of the elevator of the second embodiment. In the elevator according to the first embodiment, the button processing unit 15 of the elevator control system 1 controls all lighting and blinking of the contact type button 2, but in the elevator according to the second embodiment, the non-contact type sensor 3 is used. Also has a function to control the lighting and blinking of the contact type button 2. As shown in FIG. 8, in this embodiment, unlike the first embodiment, the elevator control system 1 does not have the sensor input determination unit 10, and the non-contact type sensor 3 is a lighting processing unit (non-contact type sensor). It has 3a, a blinking processing unit (non-contact type sensor) 3b, and a light-off processing unit (non-contact type sensor) 3c.

FIG. 9 is a diagram showing a transition from the time when the destination floor is registered by the input to the predetermined (as an example, the third floor) non-contact type sensor 3 in the second embodiment and the contact type button 2 is turned on. When the input is detected, the non-contact sensor 3 of the present embodiment first blinks the contact button 2 by the blinking processing unit (non-contact sensor) 3b, and lights up when the input time reaches the first predetermined time. The processing unit (non-contact sensor) 3a lights the contact button 2 (see A in FIG. 9). The non-contact sensor 3 lights the contact-type button 2 and transmits a signal transmitted when the contact-type button 2 is input to the elevator control system 1 in place of the contact-type button 2 (FIG. 9). See B). Then, the elevator control system 1 that has received the signal from the non-contact sensor 3 registers the destination floor by the destination floor registration unit 14. At this time, the button processing unit 15 of the elevator control system 1 transmits a lighting command signal to the contact type button 2 (see C in FIG. 9), but the contact type button 2 is lit by the non-contact type sensor 3. , The lighting state of the contact type button 2 will be maintained.

When the destination floor is canceled by the input to the non-contact sensor 3, when the input time reaches the first predetermined time, the extinguishing processing unit (non-contact sensor) 3c turns off the contact button 2 and turns off the contact button 2. , The signal transmitted when the contact type button 2 is canceled is transmitted to the elevator control system 1 by the non-contact type sensor 3. The signal at this time is the same as the cancellation (long press) when the contact type button 2 is touched for a predetermined time (for example, 1 s) or more.

FIG. 10 is a flowchart showing the processing of registration and cancellation of the destination floor by the non-contact sensor 3 of the elevator of the second embodiment.

First, the non-contact sensor 3 corresponding to each destination floor determines whether or not each destination floor can be serviced based on the signal received from the stop permission determination unit 12 of the elevator control system 1 (step S201). If the destination floor is not serviceable, registration of the destination floor is not permitted and the contact button 2 remains off. When the destination floor is serviceable, the non-contact sensor 3 determines whether or not an input has been detected (step S202). When the input is not detected, the lighting / extinguishing state of the contact type button 2 is maintained as it is. When the input is detected, the non-contact sensor 3 determines whether or not the destination floor is unregistered based on the signal received from the registration determination unit 13 of the elevator control system 1 (step S203).

When the destination floor is not registered, the non-contact sensor 3 determines whether or not the input time has reached the first predetermined time (step S204). Until the input time reaches the first predetermined time, the blinking processing unit (non-contact type sensor) 3b blinks the contact type button 2 corresponding to the destination floor (step S205). Then, when the input time reaches the first predetermined time, the lighting processing unit (non-contact type sensor) 3a lights the contact type button 2 corresponding to the destination floor (step S206). At this time, the non-contact sensor 3 transmits a signal to the elevator control system 1, and the destination floor registration unit 14 registers the destination floor (step S207).

On the other hand, when the destination floor is registered, the non-contact sensor 3 determines whether or not the input time to the non-contact sensor 3 has reached the first predetermined time (step S208). Until the input time reaches the first predetermined time, the blinking processing unit (non-contact type sensor) 3b blinks the contact type button 2 corresponding to the destination floor (step S209). Then, when the input time reaches the first predetermined time, the extinguishing processing unit (non-contact type sensor) 3c turns off the contact type button 2 corresponding to the destination floor (step S210). At this time, the non-contact sensor 3 transmits a signal to the elevator control system 1, and the destination floor registration unit 14 cancels the destination floor (step S211).

FIG. 11 is a flowchart showing the processing of registration and cancellation of the destination floor by the non-contact sensor 3 of the elevator of the third embodiment. In the elevator according to the second embodiment, when the input time to the non-contact sensor 3 reaches the first predetermined time when the destination floor is registered, the contact button 2 is immediately turned off and the destination floor is canceled. However, in the elevator according to the third embodiment, even if the input time to the non-contact sensor 3 reaches the first predetermined time, it is not canceled immediately, and the contact button 2 changes from the blinking state to the second blinking state (step). S310), the process proceeds to the preparation for cancellation (step S311).

FIG. 12 is a flowchart showing the processing by the non-contact sensor 3 after shifting to the cancellation preparation of the destination floor in FIG. 11. First, the non-contact sensor 3 corresponding to each destination floor determines whether or not the destination floor is preparing for cancellation (step 312). In the case of the destination floor being prepared for cancellation, it is determined whether or not the elapsed time from the transition to the preparation for cancellation reaches the third predetermined time (step S313). If the elapsed time from the transition to the cancellation preparation has already reached the third predetermined time, the contact type button 2 on the destination floor returns to the lit state (step S314), and the cancellation preparation is canceled (step S315). ).

Before the elapsed time from the transition to the cancellation preparation reaches the third predetermined time, it is determined whether or not the non-contact sensor 3 has detected the input again (step S316). Here, the second blinking state of the contact type button 2 is maintained while the input is not detected again, or while the input is continuously detected from the time when the preparation for cancellation is started (step S317). On the other hand, when the non-contact sensor 3 detects the input again, it is determined whether or not the input time has reached the second predetermined time (step S318). Until the input time reaches the second predetermined time, the blinking processing unit (non-contact type sensor) 3b blinks the contact type button 2 corresponding to the destination floor (step S319). Then, when the input time reaches the second predetermined time, the extinguishing processing unit (non-contact type sensor) 3c turns off the contact type button 2 corresponding to the destination floor (step S320). At this time, the non-contact sensor 3 transmits a signal to the elevator control system, and the destination floor registration unit 14 cancels the destination floor (step S321).

FIG. 13 is a diagram showing a transition in the third embodiment until the destination floor is canceled by an input to a predetermined (for example, the third floor) non-contact sensor 3 and the contact button 2 is turned off. As shown in FIG. 13, the blinking processing unit (non-contact type sensor) 3b of the present embodiment sets the contact type button 2 in the first blinking state when an input is detected, and when the input time reaches the first predetermined time. The contact-type button 2 is set to the second blinking state, and when a re-input is detected, the contact-type button 2 is set to the first blinking state (see A in FIG. 13). Then, when the input again reaches the second predetermined time, the extinguishing processing unit (non-contact type sensor) 3c turns off the contact type button 2. The non-contact sensor 3 turns off the contact button 2 and transmits a signal transmitted when canceled by the contact button 2 to the elevator control system 1 in place of the contact button 2 (FIG. 13). See B). Here, a signal similar to the cancellation (pressed twice) when the contact type button 2 is touched twice in succession, for example, a signal that turns on a few ms current and turns on a few ms current again within 1 second. Is sent. Then, the elevator control system 1 that has received the signal from the non-contact sensor 3 cancels the destination floor at the destination floor registration unit 14. At this time, the button processing unit 15 of the elevator control system 1 transmits an extinguishing command signal to the contact type button 2 (see C in FIG. 13), but the contact type button 2 is extinguished by the non-contact type sensor 3. , The off state of the contact type button 2 is maintained.

In this embodiment, the passenger is not canceled immediately by inputting the first predetermined time, but is actually canceled only when the passenger releases the hand from the non-contact sensor 3 and then brings it closer again after shifting to the cancellation preparation. Since it is canceled at the time, it is possible to suppress the cancellation without the intention of the passenger. Further, as shown in FIG. 13, when the process shifts to the cancellation preparation, the second blinking state (second blinking state) different from the normal blinking state (first blinking state) up to that point is changed, so the cancellation preparation is in progress. Passengers can recognize that. Further, when the non-contact sensor 3 detects the input again during the preparation for cancellation, the blinking state changes to the normal state, so that the passenger can recognize that there is a reaction to the operation of bringing the hand closer again. ..

Here, in the present embodiment, the second blinking state is a blinking state in which the lighting time is longer than that of the first blinking state. For example, any blinking may be used. Since the contact button 2 also blinks when the car arrives at the destination floor, the first lighting state and the second lighting state blink differently from those at the time of arrival (for example, than at the time of arrival). (Blinking for a short lighting time).

In addition, the second predetermined time, which is the threshold value of the input time for shifting from the cancellation preparation to the cancellation, is the same as the first predetermined time, which is the threshold value of the input time for shifting to the registration or cancellation preparation, so that the passengers can use the same value. The operation is easier for you to understand, but it does not have to be the same.

[Modification of Example 3]
FIG. 14 is a flowchart showing a process different from that of FIG. 12 after shifting to the cancellation preparation of the destination floor in FIG. 11 as a modification of the third embodiment. In this modification, unlike the third embodiment, the contact type button 2 is maintained in the second blinking state even when the non-contact type sensor 3 detects another input after shifting to the cancellation preparation (step S317). '). After that, when the input time reaches the second predetermined time, the contact type button 2 is turned off (step S320) and the destination floor is canceled (step S321), as in the third embodiment.

FIG. 15 is a diagram showing a transition from the time when the destination floor is canceled by the input to the predetermined (for example, the third floor) non-contact type sensor 3 and the contact type button 2 is turned off in the modified example of the third embodiment. .. As shown in FIG. 15, when the process shifts to the cancellation preparation, the second blinking state is changed as in the third embodiment. However, when the non-contact sensor 3 detects the input again during the cancellation preparation, in this modification, the input is changed. The second blinking state is maintained.

Although the non-contact sensor 3 detects the input again after shifting to the cancellation preparation, the elapsed time after shifting to the cancel preparation is first before the input time reaches the second predetermined time. When the predetermined time is reached, the cancellation preparation is canceled, and step S309 in FIG. 11 is performed as it is. In this case, in this modification, the contact type button 2 changes from the second blinking state to the normal blinking state, so that the passenger can recognize that the cancellation preparation has been canceled.

In the fourth embodiment, the mode related to registration / cancellation of the destination floor can be switched by the operation panel. FIG. 16 is a flowchart showing the mode switching process of the fourth embodiment.

First, it is determined whether or not the non-contact sensor 3 is operating normally (step S401). If the non-contact sensor 3 is not operating normally due to the microcomputer being down or the like, the mode shifts to the button-only mode that accepts only registration / cancellation by the contact button 2 (step S402). When the non-contact sensor 3 is operating normally, it is determined whether the non-contact sensor 3 is available (step S403). If the use of the non-contact sensor 3 is not permitted due to a request from the elevator administrator or the like, the mode shifts to the button-only mode (step S402).

On the other hand, when the use of the non-contact sensor 3 is permitted, the sensor operation mode shifts to the sensor operation mode in which the destination floor can be registered / canceled by both the non-contact sensor 3 and the contact button 2 (step S404). Here, the sensor operation mode of the present embodiment can be selected from a sensor priority mode in which the usability of the non-contact sensor 3 is prioritized and a button priority mode in which the usability of the contact button 2 is prioritized. (Step S405).

When the sensor priority mode is selected (step S406), for example, the first predetermined time and the second predetermined time are set as long as 0.5s to 1s, and the third predetermined time is set as long as 2s to 3s. In this case, even when registration is performed by the contact type button 2, the passenger must keep touching the 0.5 to 1 s button, and although the operability of the contact type button 2 is deteriorated, the registration is performed by the non-contact type sensor 3. Since a sufficient input time is secured until the sensor 3 is equalized, erroneous 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 predetermined time and the second predetermined time are set as short as 0 ms to several ms, and the third predetermined time is set as short as about 1 s. In this case, since the non-contact sensor 3 is also registered by simply holding it over 0 ms to several ms, the possibility of false detection by the non-contact sensor 3 increases, but the operability of the contact button 2 is improved.

FIG. 17 is a block diagram showing the configuration of the elevator according to the fifth embodiment. In the elevator according to the fifth embodiment, for example, a capacitance type Braille contact detection device 18 is connected to the non-contact type sensor 3, and the input by the non-contact type sensor 3 is cut while the Braille name plate is touched. It has become impossible to register / relate to the destination floor.

FIG. 18 is a schematic view showing the operation panel and the in-car display 4 of this embodiment. As shown in FIG. 18, a Braille name plate 19 is provided on the left side of the contact type button 2 on each destination floor, and a Braille contact detection device 18 (not shown) detects that a passenger touches the Braille name plate 19.

FIG. 19 is a flowchart showing the processing of registration and cancellation of the destination floor by the non-contact sensor 3 of the elevator of the fifth embodiment. First, the Braille contact detection device 18 determines whether or not there is contact with the Braille name plate 19 (step S501). When there is no contact with the Braille name plate 19, it is determined whether or not the elapsed time from the absence of the Braille contact has reached the fourth predetermined time (step S502). Until the fourth predetermined time is reached, the passenger who touches the Braille name plate 19 may operate the contact type button 2, so that the input of the non-contact type sensor 3 is cut (step S503). When there is contact with the Braille name plate 19, the elapsed time of the Braille name plate non-contact is reset (step S504), and the input to the non-contact sensor 3 is immediately cut (step S503). When the elapsed time of the Braille name plate non-contact reaches the fourth predetermined time, the non-contact type sensor 3 corresponding to each destination floor comes to accept the input, and is the same as in step S302 (see FIG. 11) and subsequent steps of the third embodiment. Is processed.

According to this embodiment, it is possible to prevent erroneous operation of the non-contact sensor 3 by passengers who require Braille, and it is possible to realize an elevator that is easy to use. Further, in this embodiment, when the Braille contact detection device 18 detects the contact with the Braille name plate 19, all the inputs of the non-contact type sensor 3 are cut. However, the Braille contact detection device 18 may detect which destination floor the Braille name plate 19 is in contact with, and the input may be cut only for the non-contact sensor 3 corresponding to the contacted destination floor.

FIG. 20 is a block diagram showing the configuration of the elevator of the sixth embodiment, and FIG. 21 is a schematic diagram showing the operation panel and the display in the car of the sixth embodiment. In the elevator according to the sixth embodiment, a camera is provided as a human motion detecting device 20 on the display in the car, and the human motion detecting device 20 (camera) is connected to the operation panel control device 6.

The image data taken by the camera is subjected to, for example, OpenPose method image processing, and when the movement of the passenger holding his / her hand is detected, the destination floor can be registered and canceled by the non-contact sensor 3. 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 orientation of passengers are measured, and when the measurement result satisfies a predetermined condition, a non-contact sensor is used. It may be possible to register the destination floor according to 3. For example, when the operation panel is located within a predetermined angle range with respect to the face position vector extending vertically from the center of the positions of both eyes (both shoulders) or the nose (see FIG. 22), the passenger operates the operation panel. It is judged that it is facing the board. Further, when the passenger and the operation panel are within a predetermined distance range, it is determined that the passenger is trying to operate the operation panel.

FIG. 23 is a flowchart showing the processing of registration and cancellation of the destination floor by the non-contact sensor 3 of the elevator of the sixth embodiment. In this embodiment, since the process (step S605) for detecting the presence / absence of a passenger operating the operation panel by the human motion detection device 20 is provided, whether the input of the non-contact sensor 3 was intended by the passenger. The determination can be made more accurately, and erroneous registration and erroneous cancellation of the destination floor are further suppressed. In this embodiment, an example in which a camera is used as the human motion detection device 20 has been described, but a photoelectric sensor or a capacitance sensor may be used in addition to the camera.
