Preferably, the door closing signal in step 2 is sent by a door closing button, and one of the door closing button and the inside of the elevator is provided.
This solution is used in order to facilitate the sending of a signal for closing the elevator.
Preferably, the signal verification process in step 2 is as follows:
step 21: an operator presses a door closing button to send a door closing signal;
step 22: the verification unit verifies and identifies the door closing signal;
step 23: after the identification is completed, the verification unit converts the door closing signal into a binary signal in a mechanical signal and sends the binary signal to the control center;
step 24: and the control center receives the binary signal and then sends the signal to the gate control unit.
This scheme of adoption is in order to discern the signal of closing the door, prevents misoperation.
Preferably, in step 3: the door control unit receives the door closing signal to carry out inspection, judges the correctness of the door closing signal, and starts to close the elevator door and sends a reset signal to the telescopic sill if the door closing signal is correct; if the door closing signal is incorrect, the elevator is in a door opening state.
Preferably, in step 22: if the door closing signal received by the verification unit is inaccurate, the verification unit can complement the door closing signal; and if the door closing signal received by the verification unit is accurate, the next step is carried out.
This scheme of adoption is in order to prevent that the signal of closing the door from taking place the disappearance and leading to can't carrying out the operation of closing the door.
The invention has the beneficial effects that: the elevator is provided with the door closing button, and if an operator does not press the door closing button, the elevator can be in an open state for a long time, so that cargoes or livestock can be loaded and unloaded conveniently; meanwhile, the door closing signal of the elevator can be identified and verified, and the correctness of information transmission can be ensured.
