FIG. 4 is an enlarged view of a part of the control panel in the car, in which (a) is a front view of the destination floor sensor, and (b) is a vertical cross-sectional view of the destination floor sensor. .

The passenger registers the destination floor by bringing the fingertip 40 close to the sensor portion of the destination floor sensor. For example, when registering the sixth floor as the destination floor, the passenger brings the fingertip 40 closer to the sensor portion 33f of the destination floor sensor 32f as shown in FIG. 4(a). The sensor unit 33f detects the fingertip 40 (object) and transmits the information as input information to the sensor input processing unit 72, where the destination floor is registered.

Below the destination floor sensor 32f that registers the sixth floor, a destination floor sensor 32e that registers the fifth floor is installed adjacently. When the passenger brings the fingertip 40 close to the sensor portion 33f, another finger 41 may come close to the sensor portion 33e of the destination floor sensor 32e, and the sensor portion 33e may detect the other finger 41 as an object.

The distance between the sensor portion 33f and the fingertip 40 and the distance between the sensor portion 33e and the other finger 41 are substantially the same as shown in FIG. 4(b). In the state shown in FIG. 4(b), the sensor unit 33f and the sensor unit 33e detect the input operation at the same time, so the 5th floor is registered as the destination floor in addition to the 6th floor, and the destination floor not intended by the passenger is registered. There is a possibility that Means for suppressing this will be described below.

FIG. 5 is a flow chart of an elevator device according to Embodiment 1 of the present invention.

When the sensor units 33a to 33f have detected the object (Yes in step S101), the sensor input processing unit 72 determines whether the sensor unit that has detected the object is any one of the sensor units 33a to 33f. (step S102).

If any one of the sensors 33a to 33f detects an object (Yes in step S102), the sensor input processing unit 72 sends the destination floor information corresponding to the detected sensor to the destination floor registration processing unit. 73.

The destination floor registration processing unit 73 registers the destination floor corresponding to the detected sensor unit (step S103), transmits a signal to the car operating panel 30a, and lights the lighting display units 34a to 34f corresponding to the registered destination floor. (step S107). The destination floor registration processing unit 73 also outputs to the hoisting machine drive control unit 71 a command signal for moving the car to the destination floor registered in the hoisting machine drive control unit 71 .

The hoisting machine drive control unit 71 receives the command signal from the destination floor registration processing unit 73 and controls the hoisting machine so as to move the car to the destination floor (step S108).

In step S102, when two or more adjacent sensor units have detected an object (No in step S102), the sensor input processing unit 72 determines whether two or more sensor units have simultaneously detected an object. (step S104). "Simultaneously" in the first embodiment means, for example, that the time delay between the detection of the object by the first sensor unit and the detection of the object by the second sensor unit is 0 to 0.5 seconds. Includes a range within

When two or more adjacent sensor units among the sensor units 33a to 33f detect the object at the same time (Yes in step S104), the sensor input processing unit 72 selects the floor corresponding to the sensor unit located above. This information is transmitted to the destination floor registration processing unit 73 .

The destination floor registration processing unit 73 registers only the destination floor corresponding to the sensor unit located above (step S105), transmits a signal to the car operation panel 30a, 34f is turned on (step S107). The destination floor registration processing unit 73 also outputs to the hoisting machine drive control unit 71 a command signal for moving the car to the destination floor registered in the hoisting machine drive control unit 71 .

In step S104, the sensor input processing unit 72 detects the object first when two or more sensor units detect the object over a predetermined period of time (for example, 0.5 seconds) (No in step S104). Only the destination floor information corresponding to the sensor unit is transmitted to the destination floor registration processing unit 73 .

The destination floor registration processing unit 73 registers the destination floor corresponding to the first detected sensor unit (step S106), transmits a signal to the car operation panel 30a, and lights up the lighting display units 34a to 34f corresponding to the registered destination floor. is turned on (step S107). The destination floor registration processing unit 73 also outputs to the hoisting machine drive control unit 71 a command signal for moving the car to the destination floor registered in the hoisting machine drive control unit 71 .

The operation control unit of the first embodiment is characterized in that when two or more sensor units detect objects simultaneously, only the destination floor corresponding to the upper sensor unit is registered and the hoist is controlled. and For example, as shown in FIG. 4, when a passenger registers the 6th floor as a destination floor with a fingertip 40, another finger 41 approaches the sensor unit 33e for registering the 5th floor, and the sensor unit 33e targets the other finger 41. It may be detected as an object. In this case, registering the 5th floor as the destination floor is an erroneous registration.

Therefore, in the first embodiment, focusing on the fact that the passenger can register with the fingertip 40, only the destination floor corresponding to the sensor unit located at the top is registered, thereby suppressing erroneous registration of the destination floor. When registering the destination floor, there is a high possibility that there is no object that can be detected by the sensor unit above the fingertip 40, so when two or more sensor units are detected at the same time, the sensor located at the upper part If only the destination floor corresponding to the part is registered, the destination floor intended by the passenger can be registered, and erroneous detection can be suppressed.

According to the first embodiment, it is possible to provide an elevator device and an elevator control method that suppress erroneous registration of a destination floor.
