Description

[Detailed Description of the Invention] The present invention relates to an elevator door control device.

Generally, an elevator door opens after the elevator stops landing on the floor, and starts closing when a preset door opening time expires. In addition, for the convenience of passengers, a door open button and a door close button are installed inside the car.If you want to open the door, you operate the door open button, and if you want to close the door, you operate the door close button. There is.

By the way, if a door close button is provided in the car, passengers cannot wait for the door opening time to expire and tend to close the door by operating the door close button and try to leave the elevator as soon as possible. . As a result, the elevator starts up more frequently than necessary, resulting in wasted electricity consumption, and it also causes operational efficiency to worsen as passengers often do not board the elevator all at once. For,
It is also common practice to have only a button to open the door, but not a button to close it.

However, not providing a door closing button is advantageous in terms of energy saving and inexpensive construction, but on the other hand, even in urgent cases, the door will not be closed until the door opening time has expired, and the elevator will not be able to depart. This has the disadvantage of

The present invention was created in view of the above points, and the purpose is to enable the door to be closed at any time using a door open button without providing a door close button.
Its features include a means for issuing a door opening command when a door opening button provided inside the car is operated, and a means for issuing a door opening command when the door opening time has expired or for operating the door opening button with a predetermined operation different from the above operation. The present invention also includes a means for issuing a door closing command when the door is closed.

The present invention will be explained below based on the drawings.

FIG. 1 is a diagram showing a configuration in which the present invention is implemented using a microcomputer. In the figure, 1 is a door opening button provided in the elevator car, 1a is an operation signal that is issued when door opening button 1 is operated, 2 is an operation control circuit that controls the operation of the elevator, and 2a is an elevator that can be operated arbitrarily. Landing stop signal issued when landing stops on the floor of , 3 is door open button 1
4 is a door control circuit for opening and closing the door.

An example of a program for implementing the present invention with the configuration shown in FIG. 1 will be explained based on the flowchart shown in FIG. 2. This program starts when the elevator stops landing on a certain floor and the landing stop signal 2a is issued. First, set everything to its initial state and issue a command to open the door (step 10).
The door opens. Next, go to step 20 and press the door open button 1.
Determine whether or not is pressed. Once the door opening button 1 is pressed, it is memorized and from now on, even if the door opening button 1 is released, the process proceeds to step 30. If door opening button 1 has never been pressed, proceed from step 20 to step 50.
Then, it is determined whether a predetermined period of time has elapsed. If the door opening button 1 is not pressed once until a predetermined period of time has elapsed, that is, until the door opening time has expired, the process proceeds from step 50 to step 60, where a door closing command 3b is issued and the door closing operation is started. . In step 70, it is determined whether the door closing operation has been completed.
If the door opening button 1 is not pressed after that, steps 70, 20, 50, and 60 are repeated to complete the door closing operation.

If door opening button 1 is pressed before the door opening time expires, the process proceeds from step 20 to step 30. step
In step 30, it is determined whether or not the door opening button 1 is currently being pressed. If it is being pressed, the process advances to step 40 and the door opening command 3a is issued and the door is opened. If the door is already open, the door is opened. Maintain that state. Therefore, as long as the door opening button 1 is pressed, the door is kept open by repeating steps 30 and 40. When the door open button 1 is released, the process advances from step 30 to step 60, and the door close command 3b is issued.
is emitted and the door closing operation begins. After that, door open button 1
If is not pressed, steps 70, 20, 30, and 60 are repeated to complete the door closing operation. If the door open button 1 is pressed during the door closing operation, the process advances from step 70 to steps 20 and 30. If the door open button 1 is kept pressed, the process advances to step 40, and when the door open button 1 is released, the process advances to step 60.
, and the same operations as described above are repeated. That is, in the embodiment described above, the door open state is maintained as long as the door opening button is kept pressed, and when the door opening button is pressed and then released, the door closing operation is started regardless of the expiration of the door opening time.

As described above, according to the present invention, since the door closing operation can be started at any time using the door opening button,
By not providing a door closing button, it is not only possible to achieve a cheaper configuration, but it also reduces the chances of passengers unnecessarily prompting passengers to close the door, and even in urgent cases, it is possible to do so without waiting for the expiration of the door opening time. Close the door;
The elevator can be started immediately.

Incidentally, in the above embodiment, the case where a microcomputer is used has been explained, but of course it can be easily implemented using a sequence circuit. In addition, the door closing operation using the door opening button is started by pressing and releasing the door opening button, but the distinction between door opening and door closing is not limited to the above operation method, and other methods may be used. Various modifications are possible without changing the gist of the invention.
