when the door is triggered by the delay of closing, the light reflection plate matched with the diffuse reflection switch is installed on the floor needing to delay the closing, and when the floor needing to delay the closing is increased, the light reflection plate is installed at the corresponding position. When the elevator car normally arrives at a floor where the light reflection plate is installed, the diffuse reflection switch is turned on, and the trigger delay relay is electrified with the positive electrode of the exit trigger relay coil. At this time, whether a person exists in the elevator car or not is detected through the human body sensor, and if the person exists in the elevator car, the human body sensor triggers the coil of the human body sensing relay to work. The normally open contact 5-9 of the human body induction relay is closed, a coil loop of the trigger delay relay is opened, and the normally open contact 6-10 of the trigger delay relay is closed. At the moment, the coil loop of the door opening maintaining relay works with the coil loop of the door opening maintaining time relay, the door opening maintaining time relay starts to time, the normally open contacts 5-9 of the door opening maintaining relay are closed, a door opening signal is continuously output to the elevator door opening button loop, and the door opening maintaining is realized, so that the door is delayed to be closed.
When the person sensor detects that no person exists in the elevator car, the power supply to the coil of the person sensing relay is stopped, the normally open contact 5-9 of the person sensing relay is reset after power failure, the coil loop of the trigger delay relay is disconnected, the delay door is withdrawn, and the normal door closing of the elevator is restored.
In the above embodiment, after the timing of the door-opening holding time relay is reached, the normally open contact of the door-opening holding time relay is closed, the coil loop of the exit trigger relay is put on, and the exit trigger relay is put into operation. When the normally closed contacts 2-10 of the exit trigger relay are electrically disconnected, the coil loop of the trigger delay relay is cut off, the exit delay door is closed, and the normal door closing of the elevator is restored.
In the embodiment, when a passenger presses a door closing button in the car, the door closing button relay is turned on to work, and normally open contacts 7-11 of the door closing button relay are closed to output a door closing signal to an elevator door closing button loop; normally open contacts 5-9 of the door closing button relay are closed, a coil loop of the trigger delay relay is cut off, the delay door closing is withdrawn, and normal door closing of the elevator is restored.
In the embodiment, when a passenger presses a door opening button in the car, the door opening button relay is turned on to work, and a normally open contact 7-11 of the door opening button relay is closed to output a door opening signal to the elevator; the normally closed contacts 1-9 of the door opening button relay are disconnected, the coil loop of the exit trigger relay is cut off, the elevator door is kept open again, and the door is triggered again after the exit delay is closed, so that the door is closed again.
