[0002] In order to meet certain specific needs, a switch box is generally provided in the elevator car operating box, and a number of required physical switches are provided in the switch box to turn on or off certain equipment. Since the existing elevator car operating box is provided with multiple physical switches for controlling the opening or closing of related equipment, the structure of the elevator car operating box is relatively complex, and the control circuits involved in its physical switches are also relatively complex, and the preparation cost is relatively high. In addition, in order to prevent non-professionals from misoperating these physical switches, a switch lock that uses a special key to open or close is usually provided on the switch box. These special needs usually include the following aspects:

[0003] 1. In order to meet the maintenance needs, a spot inspection switch is generally set in the switch box. When the spot inspection switch is switched to the on state, the elevator is out of normal service and is exclusively for maintenance personnel to operate and control the elevator;

[0004] 2. In order to meet the needs of the property or the owner, a light and fan switch is generally provided in the switch box to turn on or off the lighting and / or fan in the elevator car;

[0005] 3. In order to meet the emergency needs of the owners, a special switch is set in the switch box. When the special switch is switched to the on state, the elevator will no longer serve the elevator calls in the passenger area, but only serve the floor selection in the elevator car, such as the operating elevator in the hospital;

[0006] 4. In order to meet the needs of owners to actively control the operation of the elevator, a driver switch is set in the switch box. When the switch is switched to the on state, the driver will operate the elevator.

[0007] Chinese invention patent CN105460716B provides a method and system for setting the floor address of an elevator hall call board, the method comprising: the elevator main control board is triggered by a function code to enter a fully automatic setting mode or a semi-automatic setting mode of the hall call board address; in the fully automatic setting mode, the elevator main control board sequentially assigns floor values ​​to the hall call board based on the access order of the hall call board and the value of the physical floor; in the semi-automatic setting mode, the elevator main control board controls the elevator to run to any floor and open the elevator door according to the received in-car instructions, and assigns floor values ​​to the hall call board of the front door and / or the rear door according to the preset instructions of the received hall call button, based on the current physical position of the car and whether the rear door light curtain signal is valid; the elevator main control board is triggered by a function code to exit the fully automatic setting mode or the semi-automatic setting mode of the hall call board address; although this scheme does not require an increase in the cost of shaft wiring, the command input method of this scheme is relatively complicated.

[0008] Therefore, the present invention provides a car operation command input device and method for realizing different control functions using the action logic of the existing light curtain door protection device. Summary of the invention
