Description

Elevator and control method for elevator

Technical Field

The present invention relates to an elevator and a control method of the elevator.

Background

An operation panel is provided in a car of an elevator, and a passenger registers a destination floor by a button operation of the operation panel or the like. In addition, there is also an elevator having a non-contact sensor on an operation panel, and in such an elevator, the sensor can register a destination floor by detecting an input from a passenger. In addition, in an operation panel using a noncontact sensor, an operation panel is formulated to prevent passengers from performing erroneous registration of unexpected destination layers.

For example, patent document 1 describes "comprising: a car operating panel which is a non-contact operating panel having a plurality of sensors for non-contact detection of operations of a destination layer; and a control device that controls whether to register the destination layer based on a detection condition for detecting the operation. When the operation is detected by a destination layer sensor corresponding to the destination layer among the plurality of sensors until the 1 st threshold time, the control device registers the destination layer, and when the operation is detected until the 2 nd threshold time, a process of notifying the operation is executed to release the registration (abstract of patent document 1).

Disclosure of Invention

Problems to be solved by the invention

As described above, in the technique described in patent document 1, when the operation of the destination layer sensor is detected for the 2 nd threshold time, the registration of the destination layer is released in order to prevent the unexpected erroneous registration of the passenger such as the personal luggage, or a part of the body of the passenger from being continuously detected (paragraph 0040 of patent document 1, etc.). However, for example, when a passenger registers a certain destination and puts his/her hand on the sensor, if the sensor of the adjacent destination detects this operation, the detection time may not be continued to the 2 nd threshold time. In such a case, the registration of the unexpected destination floor of the passenger is not released, and the erroneous registration of the destination floor is maintained.

The invention aims to provide an elevator and a control method of the elevator, even if a non-contact sensor performs false detection, a destination layer can be cancelled through the operation of a passenger, and the use convenience can be improved.

Means for solving the problems

In order to solve the above problems, an elevator according to the present invention includes: a non-contact sensor that detects an input from a passenger; and a display unit that is turned on when the destination layer is registered by the sensor, wherein the display unit is turned on, and when the sensor detects a first predetermined operation, the display unit displays a preparation process for notifying cancellation, and when the sensor detects a second predetermined operation, the display unit is turned off.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, an elevator and a control method of the elevator are provided, which can cancel a destination floor by the operation of a passenger even if a non-contact sensor performs false detection, thereby improving the use convenience. Further, according to the present invention, since the elimination of the destination floor unexpected by the passenger is also prevented, the convenience of use for the passenger is further improved.

Detailed Description

Embodiments of the present invention will be described below in detail with reference to examples 1 to 6.

Example 1

Fig. 1 is a block diagram showing the structure of an elevator according to embodiment 1. Although not shown, the elevator of the present embodiment includes a car, a counterweight, a main rope, a hoisting machine, and the like, and the main rope is driven by the hoisting machine to lift the car and the counterweight in a hoistway.

The car is provided with: an operation panel provided with a touch button 2 and a noncontact sensor 3; an in-car display 4 such as a liquid crystal display located at the upper part of the operation panel; and a sound output device 5 such as a speaker. The touch button 2 and the noncontact sensor 3 are controlled by an operation panel control device 6, the in-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 via a tail rope or the like. The touch button 2 includes a display portion that is turned on when the destination layer is registered.

Fig. 2 is a schematic view showing an operation panel and an in-car display 4 according to the present embodiment. As shown in fig. 2, a noncontact sensor 3 is provided on the right side of the touch button 2 of each destination layer. The touch button 2 is composed of, for example, a display panel on which a floor number is printed, an electrode plate which is located on the back side of the display panel and has light transmittance, a detection circuit which detects a change in capacitance of the electrode plate, and a light source which irradiates printing light when the touch button is turned on. When a passenger in the car touches the touch button 2 corresponding to a desired destination floor, the capacitance of the electrode plate changes, and the touch button 2 is lighted by irradiating the display panel with light from the light source, so that the passenger can recognize that the operation of the destination floor is performed.

The noncontact sensor 3 uses a Time of Flight (TOF) sensor as well as a photoelectric sensor and an electrostatic capacitance sensor. When the passenger uses the glove to send a signal to the touch button 2 at a predetermined time from the non-contact sensor 3 corresponding to a desired destination, the light source irradiates light to illuminate, and therefore, the passenger can recognize that the operation of the destination is performed as in the case of touching the touch button 2.

Next, the structure of the elevator control system 1 will be described with reference to fig. 1. The elevator control system 1 is placed in a machine room or the like and controls the speed of a motor of a hoisting machine or the like, but in this specification, description will be made centering on a portion related to control of an operation panel. As shown in fig. 1, the elevator control system 1 of the present embodiment is configured by 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 layer registration unit 14, a button processing unit 15, a display processing unit 16, and a sound processing unit 17.

The transceiver 9 receives signals from the operation panel control device 6 when the touch button 2 and the noncontact sensor 3 in the car are operated, and transmits operation information from the operation panel and output information (floor position, moving direction, etc.) of the elevator 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 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 sensor 3 based on the signal received by the transmitting/receiving unit 9. When the button input determination unit 11 or the sensor input determination unit 10 determines that an input is present, the stop permission determination unit 12 determines whether or not to permit stopping at the destination layer to which the input is present. For example, when a floor or the like where a tenant is not located is input as a destination floor, the stop permission determination unit 12 considers that the destination floor cannot be served, and does not permit stopping. 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 to display the meaning that the destination floor cannot be registered on the in-car display 4, and the sound processing unit 17 transmits a signal to the sound control device 8 via the transmission/reception unit 9 to broadcast the meaning that the destination floor cannot be registered on the sound output device 5.

The registration determination unit 13 determines whether or not the destination layer for which the stop permission determination unit 12 permits stop has been registered. The destination layer registration unit 14 newly performs registration processing when the destination layer having input is unregistered, and performs cancellation processing when the destination layer having input is registered. When the registration or cancellation process is performed, the destination floor registration unit 14 transmits signals to the display processing unit 16, the sound processing unit 17, and the button processing unit 15, and notifies passengers in the car.

The button processing section 15 includes a lighting processing section 15a, a blinking processing section 15b, and a turning-off processing section 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 unit 9 to light the touch button 2. When the cancellation of the destination layer is performed, the extinction processing unit 15c transmits a signal to the operation panel control device 6 via the transmitting/receiving unit 9, and extinguishes the touch button 2. The blinking processing section 15b temporarily blinks the touch button 2 until the registration or cancellation process is completed from the input of the destination layer.

Fig. 3 is a diagram showing, as an example, a state in which the touch button 2 of the 3 layers temporarily blinks by the non-contact sensor 3 covered on the right side of the touch button 2 of the 3 layers. In the present embodiment, even if there is an input of the non-contact sensor 3 to an unregistered destination floor, the erroneous registration by the input of an unintentional instant can be suppressed by setting the input time to a blinking state as shown in fig. 3 until the input time reaches the 1 st given time. Even when the registered destination floor has the input of the noncontact sensor 3, the passenger is not immediately canceled, and the passenger is similarly set to a temporary blinking state, thereby suppressing unintended cancellation of the passenger.

Fig. 4 is a diagram showing, as an example, a state in which the input time to the non-contact sensor 3 reaches the 1 st predetermined time, and the 3 layers are registered as the target layers, and the 3 layers touch button 2 is turned on. Fig. 5 is a diagram showing a case where 3 layers are registered as the target layers and the touch button 2 of 3 layers remains lit even when the hand is stopped from being covered by the non-touch sensor 3. In this way, even when the passenger covers the hand with the non-contact sensor 3, the touch button 2 is lit up similarly to the case of touching the touch button 2, and therefore, a structure such as a light source is not required to be separately provided for the non-contact sensor 3.

Fig. 6 is a flowchart showing the process 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 or not the non-contact sensor 3 of a certain destination layer detects an input (step S101). In the case where the input of the noncontact sensor 3 is not detected, the on/off state of the touch 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 or not the destination layer having the input is available for service (step S102). When the destination floor with input is not able to be serviced, the off state of the touch button 2 is maintained as it is, and the passenger is notified of the fact that the destination floor is not able to be stopped by the in-car display 4 and the audio output device 5. When the input destination layer can serve, the registration determination unit 13 determines whether or not the destination layer is unregistered (step S103).

When the destination is not registered, the destination registration unit 14 determines whether or not the input time to the non-contact sensor 3 reaches the 1 st predetermined time (step S104). Until the input time reaches the 1 st predetermined time, the button processing unit 15 blinks the touch button 2 corresponding to the destination layer (step S105). When the input time reaches the 1 st predetermined time, the destination registering unit 14 registers the destination (step S106), and the button processing unit 15 changes the touch button 2 corresponding to the destination from the blinking state to the lighted state (step S107). When the input is no longer detected until the input time reaches the 1 st predetermined time, the button processing unit 15 changes the touch button 2 corresponding to the target layer from the blinking state to the turning-off state.

In addition, step S102 may be omitted, or a maintenance mode may be set and skipped during the maintenance mode, and the operation may be advanced to the on/off operation of the touch button 2 regardless of the presence or absence of the stop layer. The maintenance mode can be switched, for example, when a maintenance switch in the car is turned on and when a maintenance command is input to the elevator control system 1 so that authentication/comparison of the command is established. The method of canceling this mode includes a case where a maintenance switch in the car is turned off, a case where a maintenance command is again input to the elevator control system 1, and authentication/comparison of the command is established. In the maintenance mode, only the operating state of the non-contact sensor 3 and the blinking state of the contact button 2 may be checked without receiving a call registration from the sensor. The structure may also be as follows: in this mode, regardless of steps S103 to S111 shown in fig. 6, the non-contact sensor 3 simply determines whether or not input is possible, blinks when input is detected, and turns off when not detected. In the case where the non-contact sensor 3 of a layer other than the stop layer is operated without this step, the touch button 2 blinks until a predetermined time, and if the predetermined time elapses, guidance is performed in the sense that the layer cannot be served. For example, sound guidance such as the inability to use in the layer is given.

Fig. 7 is a diagram showing a transition from registering a target layer by input to a given (for example, 3 layers) non-contact sensor 3 to lighting up the touch button 2 in example 1. In this way, by blinking the touch button 2 until the input time reaches the 1 st predetermined time and the touch button is turned on, the passenger can recognize that the non-contact sensor 3 is reacting, and the convenience of use is improved.

On the other hand, when the destination registering is completed, the destination registering unit 14 determines whether or not the input time to the non-contact sensor 3 reaches the 1 st predetermined time (step S108). Until the input time reaches the 1 st predetermined time, the button processing unit 15 blinks the touch button 2 corresponding to the target layer (step S109). When the input time reaches the 1 st predetermined time, the destination registering unit 14 cancels the destination (step S110), and the button processing unit 15 changes the touch button 2 corresponding to the destination from the blinking state to the turning-off state (step S111). When the input is not detected until the input time reaches the 1 st predetermined time, the button processing unit 15 changes the touch button 2 corresponding to the target layer from the blinking state to the lighting state.

According to the present embodiment, since the registration is performed only when the input time to the non-contact sensor 3 reaches the 1 st predetermined time, the unexpected registration of the passenger can be suppressed. Even when the non-contact sensor 3 performs erroneous detection and registers, the destination floor can be canceled by the operation of the passenger himself, and the convenience of use of the elevator can be improved. Further, since the threshold value of the input time to the noncontact sensor 3 is set to the 1 st given time in common at the time of registration and the time of cancellation, the operation is easy for the passenger to understand. However, if it is desired to perform the registration operation with a high frequency of use in a short time, the threshold value of the input time at the time of registration may be set shorter than that at the time of cancellation.

Example 2

Fig. 8 is a block diagram showing the structure of an elevator according to embodiment 2. In the elevator according to embodiment 1, the lighting and blinking of the touch button 2 are controlled by the button processing unit 15 of the elevator control system 1, but in the elevator according to embodiment 2, the noncontact sensor 3 also has a function of controlling the lighting and blinking of the touch button 2. As shown in fig. 8, in the present embodiment, unlike in embodiment 1, the elevator control system 1 has no sensor input determination unit 10, and the non-contact sensor 3 has a lighting processing unit (non-contact sensor) 3a, a blinking processing unit (non-contact sensor) 3b, and an extinction processing unit (non-contact sensor) 3c.

Fig. 9 is a diagram showing a transition from registering a target layer to lighting of the touch button 2 by input to a given (for example, 3 layers) of the non-touch sensor 3 in example 2. When the noncontact sensor 3 of the present embodiment detects an input, the blinking processing section (noncontact sensor) 3b blinks the contact button 2, and when the input time reaches the 1 st predetermined time, the lighting processing section (noncontact sensor) 3a lights the contact button 2 (see a of fig. 9). The noncontact sensor 3 lights up the touch button 2 and transmits a signal transmitted when the touch button 2 is input to the elevator control system 1 instead of the touch button 2 (refer to B of fig. 9). Then, the elevator control system 1, which receives the signal from the non-contact sensor 3, registers the destination layer by using the destination layer registration unit 14. At this time, the button processing unit 15 of the elevator control system 1 transmits a command signal for lighting up the touch button 2 (see C in fig. 9), but the touch button 2 is lighted up by the non-contact sensor 3, so that the lighted up state of the touch button 2 is maintained.

When the destination layer is canceled by the input of the non-contact sensor 3, if the input time reaches the 1 st predetermined time, the extinction processing unit (non-contact sensor) 3c extinguishes the contact button 2, and transmits a signal transmitted when the contact button 2 is canceled to the elevator control system 1 via the non-contact sensor 3. The signal at this time is the same as (long press) cancellation when the touch button 2 is touched for a predetermined time (for example, 1 s) or longer.

Fig. 10 is a flowchart showing the process of registering and canceling a destination floor by the non-contact sensor 3 of the elevator according to example 2.

First, the non-contact sensor 3 corresponding to each destination floor determines whether or not each destination floor is available for service based on the signal received from the stop permission determination unit 12 of the elevator control system 1 (step S201). When the destination floor cannot be serviced, registration of the destination floor is not permitted, and the touch button 2 remains turned off. In the case where the destination layer can serve, the non-contact sensor 3 determines whether or not an input is detected (step S202). In the case where no input is detected, the on/off state of the touch button 2 is maintained unchanged. When an input is detected, the non-contact sensor 3 determines whether or not the destination floor is unregistered based on a signal received from the registration determination unit 13 of the elevator control system 1 (step S203).

In the case where the destination layer is not registered, the non-contact sensor 3 determines whether or not the input time reaches the 1 st given time (step S204). Until the input time reaches the 1 st predetermined time, the blinking processing section (noncontact sensor) 3b blinks the touch button 2 corresponding to the target layer (step S205). Then, when the input time reaches the 1 st predetermined time, the lighting processing unit (non-contact sensor) 3a lights up the touch button 2 corresponding to the target layer (step S206). At this time, the noncontact sensor 3 transmits a signal to the elevator control system 1, and the destination layer registration unit 14 registers the destination layer (step S207).

On the other hand, when the destination layer registration is completed, the non-contact sensor 3 determines whether or not the input time to the non-contact sensor 3 reaches the 1 st predetermined time (step S208). Until the input time reaches the 1 st predetermined time, the blinking processing section (noncontact sensor) 3b blinks the touch button 2 corresponding to the target layer (step S209). Then, when the input time reaches the 1 st predetermined time, the extinction processing unit (non-contact sensor) 3c extinguishes the touch button 2 corresponding to the target layer (step S210). At this time, the noncontact sensor 3 transmits a signal to the elevator control system 1, and the destination registering unit 14 cancels the destination (step S211).

Example 3

Fig. 11 is a flowchart showing the process of registering and canceling a destination floor by the non-contact sensor 3 of the elevator in example 3. In the elevator according to example 2, when the destination floor is registered, if the input time to the non-contact sensor 3 reaches the 1 st predetermined time, the contact button 2 is immediately turned off, and the destination floor is canceled. However, in the elevator according to embodiment 3, even if the input time to the non-contact sensor 3 reaches the 1 st predetermined time, the cancel is not immediately performed, but the contact button 2 is changed from the blinking state to the second blinking state (step S310), and the operation shifts to the cancel preparation (step S311).

Fig. 12 is a flowchart showing a process performed by the noncontact sensor 3 after the preparation for cancellation, which has been shifted to the target layer in fig. 11. First, the non-contact sensor 3 corresponding to each destination layer determines whether or not the destination layer is in preparation for cancellation (step 312). If the destination layer is in the cancel preparation, it is determined whether or not the elapsed time from the transition to the cancel preparation reaches the 3 rd predetermined time (step S313). When the elapsed time from the transition to cancel preparation has reached the 3 rd predetermined time, the touch button 2 of the destination layer is restored to the on state (step S314), and cancel preparation is released (step S315).

Before the elapsed time from the transition to cancel preparation reaches the 3 rd given time, it is determined whether or not the non-contact sensor 3 detects an input again (step S316). Here, the second blinking state of the touch button 2 is maintained while no renewed input is detected or while an input is continuously detected from the time of transition to cancel preparation (step S317). On the other hand, when the non-contact sensor 3 detects an input again, it is determined whether or not the input time reaches the 2 nd given time (step S318). Until the input time reaches the 2 nd predetermined time, the blinking processing part (noncontact sensor) 3b blinks the touch button 2 corresponding to the target layer (step S319). Then, when the input time reaches the 2 nd predetermined time, the extinction processing unit (non-contact sensor) 3c extinguishes the touch button 2 corresponding to the target layer (step S320). At this time, the noncontact sensor 3 transmits a signal to the elevator control system, and the destination registering unit 14 cancels the destination (step S321).

Fig. 13 is a diagram showing a transition from canceling the input destination layer to the given (for example, 3 layers) non-contact sensor 3 to turning off the contact button 2 in example 3. As shown in fig. 13, the blinking processing section (noncontact sensor) 3b of the present embodiment sets the touch button 2 to the 1 st blinking state when an input is detected, sets the touch button 2 to the 2 nd blinking state when the input time reaches the 1 st predetermined time, and sets the touch button 2 to the 1 st blinking state when a renewed input is detected (refer to a of fig. 13). Then, when the input again reaches the 2 nd predetermined time, the extinction processing unit (non-contact sensor) 3c extinguishes the contact button 2. The noncontact sensor 3 extinguishes the touch button 2 and transmits a signal transmitted when the touch button 2 is canceled to the elevator control system 1 in place of the touch button 2 (refer to B of fig. 13). Here, the same signal as the cancellation (2 times) when the touch button 2 is touched 2 times in succession, for example, a signal that turns on a current for several ms and turns on a current for several ms again within 1 second, is transmitted. Then, the elevator control system 1, which receives the signal from the non-contact sensor 3, cancels the destination floor by the destination floor registration section 14. At this time, the button processing unit 15 of the elevator control system 1 transmits an instruction signal to turn off the touch button 2 (see C of fig. 13), but the touch button 2 is turned off by the non-contact sensor 3, so that the off state of the touch button 2 is maintained.

In the present embodiment, the passenger is not immediately canceled at the input of the 1 st given time, but is actually canceled when he/she makes an operation of getting his/her hands away from the non-contact sensor 3 and getting them closer again after shifting to the cancellation preparation, and therefore, unintended cancellation of the passenger can be suppressed. Further, as shown in fig. 13, when the vehicle shifts to the cancel preparation, the vehicle shifts to the second blinking state (2 nd blinking state) different from the normal blinking state (1 st blinking state) before that, and therefore, the passenger can recognize that the vehicle is in the cancel preparation. Further, when the noncontact sensor 3 detects an input again during the cancellation preparation, the state is changed to the normal blinking state, and thus the passenger can recognize that the operation of bringing the hand closer again is reacted.

In the present embodiment, the 2 nd blinking state is a blinking state in which the lighting time is longer than that in the 1 st blinking state, but any blinking may be used as long as the passenger is easily distinguished from the manner in which the 1 st blinking state is lit. Further, since the touch button 2 is also in the blinking state when the car reaches the destination floor, the 1 st lighting state and the 2 nd lighting state are in a blinking manner different from those when they reach (for example, blinking for a shorter lighting time than when they reach).

The threshold value of the input time for shifting from cancel preparation to cancel, i.e., the 2 nd given time, is the same as the threshold value of the input time for shifting to register and cancel preparation, i.e., the 1 st given time, and it is easy for the passenger to understand the operation, but it may be different.

Modification of example 3

Fig. 14 is a flowchart showing a process different from fig. 12 after the preparation for canceling the transition to the destination layer in fig. 11 as a modification of embodiment 3. In the present modification, unlike in embodiment 3, even when the non-contact sensor 3 detects a renewed input after shifting to cancel preparation, the contact button 2 maintains the second blinking state (step S317'). After that, when the input time reaches the 2 nd predetermined time, the touch button 2 is turned off (step S320) and the destination layer is canceled (step S321) in the same manner as in example 3.

Fig. 15 is a diagram showing a transition from canceling the target layer by inputting the target layer to the given (3 layers as an example) non-contact sensor 3 to turning off the contact button 2 in the modification of the embodiment 3. As shown in fig. 15, when the cancel preparation is shifted, the state is changed to the 2 nd blinking state in the same manner as in example 3, but in the case where the noncontact sensor 3 detects the input again during the cancel preparation, the 2 nd blinking state is maintained in the present modification.

In addition, when the non-contact sensor 3 detects the input again after the shift to cancel the preparation, but the elapsed time after the shift to cancel the preparation reaches the 3 rd predetermined time before the input time reaches the 2 nd predetermined time, the cancel preparation is canceled, and the process proceeds to step S309 in fig. 11 as it is. In this case, in the present modification, the contact button 2 is changed from the second blinking state to the normal blinking state, and thus the passenger can recognize that the cancellation preparation is released.

Example 4

Embodiment 4 switches modes related to registration/cancellation of a destination layer by an operation panel. Fig. 16 is a flowchart showing the process of mode switching in embodiment 4.

First, the non-contact sensor 3 determines whether or not the operation is normal (step S401). When the non-contact sensor 3 does not operate normally due to a microcomputer breakdown or the like, the operation shifts to a button dedicated mode that accepts only registration/cancellation by the contact button 2 (step S402). When the non-contact sensor 3 is operating normally, the non-contact sensor 3 determines that it is available (step S403). When the use of the non-contact sensor 3 is not permitted according to the wishes of the manager of the elevator or the like, the operation shifts to the button dedicated mode (step S402).

On the other hand, when the use of the noncontact sensor 3 is permitted, the operation shifts to a sensor operation mode in which registration/cancellation of the destination layer can be performed by both the noncontact sensor 3 and the touch button 2 (step S404). Here, the sensor operation mode of the present embodiment can select a sensor priority mode that prioritizes the convenience of use of the non-contact sensor 3 and a button priority mode that prioritizes the convenience of use of the contact button 2 (step S405).

When the sensor priority mode is selected (step S406), for example, the 1 st predetermined time and the 2 nd predetermined time are set to be longer than 0.5S to 1S, and the 3 rd predetermined time is set to be longer than 2S to 3S. In this case, even in the case of registration or the like by the touch button 2, the passenger must continuously touch the button for 0.5 to 1s, and the operability of the touch button 2 is reduced, but since the input time until registration or the like by the non-contact sensor 3 is sufficiently secured, erroneous detection by the non-contact sensor 3 is suppressed. On the other hand, when the button priority mode is selected (step S407), for example, the 1 st predetermined time and the 2 nd predetermined time are set to be as short as 0ms to several ms, and the 3 rd predetermined time is set to be as short as 1S. In this case, the noncontact sensor 3 is also registered only for 0ms to several ms, and thus the operability of the touch button 2 is improved although the possibility of erroneous detection by the noncontact sensor 3 is improved.

Example 5

Fig. 17 is a block diagram showing the structure of an elevator according to embodiment 5. In the elevator according to example 5, for example, the capacitive type braille touch detecting device 18 is connected to the noncontact sensor 3, and the input by the noncontact sensor 3 is cut off during the time of touching the braille sign, so that the registration/cancellation of the destination layer is no longer possible.

Fig. 18 is a schematic view showing an operation panel and an in-car display 4 according to the present embodiment. As shown in fig. 18, a braille sign 19 is provided on the left side of the touch button 2 of each destination layer, and a braille touch detection device 18, not shown, detects that the passenger touches the braille sign 19.

Fig. 19 is a flowchart showing the process of registering and canceling a destination floor by the non-contact sensor 3 of the elevator according to example 5. First, the braille contact detection device 18 determines whether there is no contact with the braille label 19 (step S501). In the case where there is no contact to the braille label 19, it is determined whether or not the elapsed time since the disappearance of the braille contact reaches the 4 th given time (step S502). Since the passenger touching the braille plate 19 has a possibility of operating the touch button 2 until the 4 th given time, the input of the non-contact sensor 3 is cut off (step S503). When the contact of the braille label 19 occurs, the elapsed time of the non-contact of the braille label is reset (step S504), and the input to the non-contact sensor 3 is immediately cut off (step S503). When the time elapsed after the non-contact of the braille label reaches the 4 th predetermined time, the non-contact sensor 3 corresponding to each destination layer receives an input, and the same processing as in step S302 (see fig. 11) of example 3 is performed.

According to the present embodiment, the erroneous operation of the noncontact sensor 3 by the passenger who needs the braille can be prevented, and the elevator with excellent use convenience can be realized. In the present embodiment, when the contact of the braille contact detecting means 18 with the braille label 19 is detected, the input of all the noncontact sensors 3 is cut off. However, the braille contact detection device 18 may detect which target layer the braille label 19 contacts, and only the input of the non-contact sensor 3 corresponding to the contacted target layer may be cut off.

Example 6

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

For example, image data captured by the camera is subjected to image processing of the openwise system, and when a passenger's hand-covering operation is detected, registration and cancellation of a destination layer by the non-contact sensor 3 are enabled. Further, when a camera equipped with an image sensor such as a TOF sensor is used as the human motion detection device 20, the distance and the direction of the passenger may be measured, and when the measurement result satisfies a predetermined condition, registration of the destination layer or the like by the non-contact sensor 3 may be performed. For example, when the operation panel is positioned within a predetermined angular range with respect to a position vector of a face extending in the vertical direction from the center of the positions of both eyes (both shoulders) or the nose (refer to fig. 22), it is determined that the passenger is facing the direction of the operation panel. Further, when the passenger and the operation panel are located within a predetermined distance range, it is determined that the passenger wants to operate the operation panel.

Fig. 23 is a flowchart showing the process of registering and canceling a destination floor by the non-contact sensor 3 of the elevator according to example 6. In the present 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 or not the input of the non-contact sensor 3 is the input expected by the passenger, and further, erroneous registration and erroneous cancellation of the destination floor are suppressed. In the present embodiment, the example of using a camera 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.

The embodiments of the present invention have been described above by way of example 1 to example 6, but the present invention is not limited to example 1 to example 6, and various modifications are included. In addition, a part of the structure of one embodiment may be replaced with the structure of another embodiment, and the structure of another embodiment may be added to the structure of one embodiment. In addition, other structures may be added, deleted, or replaced in part of the structures of the embodiments.
