Abstract

PURPOSE:To provide a door control device for elevator free of risk of generating misoperation for a door shout button and door open button in the car. CONSTITUTION:With a door control device 4 for elevator, the door is opened after the elevator landing motion has stopped (Step 20), and when the preset door-open limit time is filled (Step 30), the door opening is started (Step 40), wherein the arrangement includes a means to issue a door shut command 3a when a door shut button 1 installed in the car is pushed and a means to emit a door-open command 3b when the door shut button 1 is pushed at the time the door open time is up (Step 30) or while the door is in the shutting motion (Step 60).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator door control device.

[0002]

2. Description of the Related Art Generally, an elevator door is designed to open after the elevator stops landing and starts to close when a preset door opening time expires. Also, for the convenience of passengers, a door close button and a door open button are provided in the car.If you want to close the door, operate the door close button, and if you want to open the door, operate the door open button. It was structured.

[0003]

In the above-mentioned conventional structure, when a passenger in a hurry tries to close the door by operating the door close button, he / she operates the door open button by mistake, while rushing to open the door. I tried to operate the door open button to open it, but I accidentally operated the door close button. For this reason, two types of buttons, a door-close button and a door-open button, are provided to deteriorate the proper operating efficiency of the elevator and to hit other passengers against the door, which is against the intention of the operator. However, there is a problem in that it is easy to make an operation mistake because it is being used.

An object of the present invention is to provide an elevator door control device that does not cause an operation error.

[0005]

[Means for Solving the Problems] The above object is to provide a door control device for an elevator, in which a door is opened after landing of the elevator is stopped, and the door is closed when a preset door opening time expires. A means for issuing a door closing command in response to an operation of the door closing button provided in, and a means for issuing a door opening command when the door closing button is operated when the door opening time has expired or during the door closing operation. It can be achieved by having it.

[0006]

The door closing button provided in the car gives a door closing command when operated before the door opening time expires and gives a door opening command when operated after the door opening time expires or during the door closing operation. Therefore,
Only one button is operated, and no mistaken operation occurs.

[0007]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram when the present invention is realized by using a microcomputer. 1 is a door closing button provided in a car of an elevator, 1a is an operation signal emitted when the door closing button is operated, 2 is an operation control circuit for controlling the operation of the elevator, 2a is an elevator on an arbitrary floor A landing stop signal 3 which is issued when the flooring is stopped determines a door closing command 3a or a door opening command 3 by discriminating a difference in operation of the door closing button 1.
The microcomputer 4 which emits b is a door control circuit for opening and closing the door.

An example of a program for implementing the present invention having the configuration of FIG. 1 will be described with reference to the flowchart of FIG. This program starts when the floor stops on the floor where the elevator is located and the floor stop signal 2a is issued. First, all are set to the initial state and a door open command (step 10) is issued to open the door. Next, in step 20, it is confirmed that the opening operation of the door is completed. Next step 30
At, it is determined whether or not a predetermined time period has elapsed. When the door close button 1 has not been pressed until the predetermined time period elapses, that is, until the predetermined time period expires, the process proceeds to step 40, where the door closing command 3a is issued, the door closing operation is started, and the process proceeds to step 50. At this time, it is determined whether or not the door close button 1 is pressed, and when the door close button 1 is not pressed, the routine proceeds to step 60. After that, when the door close button 1 is not pressed, steps 50 and 60 are repeated until the door close operation is completed, and the door close operation is completed.

Now, when the door close button 1 is pressed before the expiration of the door open time limit, from step 30 to step 70.
When it is operated, it is also memorized, and thereafter, even if the door close button 1 is released, the process proceeds to step 80, the door closing command 3a is issued, the door closing operation is started, and the process proceeds to step 90. Next, at step 90, after a predetermined time period has passed, the routine proceeds to step 50. At this time, when the door close button 1 is not pressed, step 6
0, steps 50 and 60 until the door closing operation is completed
Is repeated and the door is closed. If the door close button 1 is pressed, the process proceeds from step 50 to step 10,
The door opening command 3b is issued, the door opening operation is performed, and the door is opened. Therefore, while the door close button 1 is being pressed, from step 20, steps 30, 70, 80, 90, 50, 1
The door open state is maintained by repeating 0 and 20. When the door close button 1 is released, the process proceeds from step 30 to step 40, the door close command 3a is issued, and as described above, the process proceeds from step 50 to step 60 to complete the door close operation.
Further, when the door close button 1 is pressed before the completion of the door close operation in step 60, the process proceeds from step 60 to step 50 and step 10, and thereafter, the same repetition as described above is performed. That is, in the present embodiment, while the door close button 1 is continuously pressed, after a predetermined time period has elapsed, the door close button 1 issues the door open command 3b, performs the door open operation, and enters the door open state. As a result, since only one button is operated, an operation error will not occur.

When it is desired to keep the door open, it is possible to keep the safety shoe pressed. Further, in the present embodiment, the door close button is displayed, but
No need to display.

[0012]

According to the present invention, there is only one operation button for opening and closing the door in the car. Therefore, contrary to the operator's will, there is no need to make an operation mistake and perform an unnecessary door opening / closing operation.
