Description

Elevator moving floor control device and method

The present invention relates to an elevator operating floor control apparatus and method, and more particularly to an elevator operating floor control apparatus and method that can increase the use efficiency and reduce power consumption by setting and operating a floor that can be easily or manually operated. It is about.

In general, the elevator is controlled by the serial communication between the control panel and the boarding interface board. The driving control by serial communication increases power consumption as the number of floors in which an elevator operates increases, that is, as the number of floors in a building increases, with reference to the accompanying drawings of the conventional elevator operating floor control apparatus and method. The explanation is as follows.

1 is a block diagram of a general elevator driving floor control apparatus, and a control panel 10 for transmitting a control signal according to various driving commands of a driver as shown in the drawing; A plurality of boarding interface boards 20 receiving power signals and control signals of the control panel from the control panel 10 through the power lines P1 and P2 and the communication lines T1 and T2 to display the driving state of the car on each floor. It consists of.

A communication control unit 25 which outputs a display signal and is initialized according to the reset signal of the reset unit 24; A call call display unit 26 which displays a call request so that the passenger can recognize that the button has been pressed according to the call display signal of the communication control unit 25; The floor display unit 28 is configured to display a floor in which a car is located according to a drive signal of the floor display driver 27 that operates according to the floor display control signal of the communication controller 25.

Hereinafter, the operation of the conventional elevator running floor control apparatus will be described.

First, when a passenger presses a button to move to another floor, the button interface unit 23 outputs a call signal to indicate that a button in a downward or upward direction is pressed, that is, a call request is made. Notify

Subsequently, the communication controller 25 notifies the control panel 10 that there is a call request on a specific floor through the communication lines T1 and T2 connected to the communication interface 22 and the connection unit 21. The call display unit 26 displays the call display unit 26 so that the passenger requesting the call can recognize that the button is pressed.

Even during such an operation process, the control panel 10 transmits the position of the car to the communication control unit 25 through the communication lines T1 and T2, the connection unit 21, and the communication interface 22. The position of the car is displayed on the floor display unit 28 through the floor display driver 27.

Then, the control panel 10 that receives the call signal of the boarding interface board 20 installed on the specific floor moves the car to the floor where the call signal is transmitted.

In this process, when the car is not operated on a specific floor for the purpose of reducing power consumption, for example, when the car is operated on a second floor, a third floor, or on a separate floor that can be walked through the stairs, the car is operated. In the method of setting a floor not to be separated, the communication lines T1 and T2 and the power lines P1 and P2 connected to the connection portion 20 of the elevating interface board 20 are separated to set a floor on which the car does not run.

As described above, in the conventional elevator driving floor control method, a maintenance worker moves to the elevating interface board installed in each floor to set a floor on which the car is not driven, and it takes a long time by separating the connection part where the communication line and the power line are connected. There was a problem that the efficiency is lowered.

In view of the above problems, the present invention has an object to provide an elevator driving floor control apparatus and method that can limit the floor of the car automatically or manually by the operator's setting.
