(1) all hall call instructions, in-car operation instructions and registered operation instructions are cancelled;
(2) the door opening system and the emergency system arranged in the car keep working, and the anti-door opening system stops working;
(3) the elevators are immediately separated from group control or parallel control and perform emergency return work independently;
(4) the fire-fighting emergency return instruction cannot preferentially overhaul the control state and the emergency electric control state, and cannot cut off the operation states of the control state and the emergency electric control state, and sound signals in an elevator machine room and a car immediately sound until the overhaul or the emergency electric control state is cancelled;
(5) the elevator machine room and the hoistway lighting system are automatically turned on;
(6) when the elevator is at different positions, different steps are executed for operation;
as a preferred embodiment of the present invention: the fire switch is arranged above a base station calling button which can safely evacuate people.
As a preferred embodiment of the present invention: the fire switch is in communication connection with an elevator control system in an elevator duty room.
As a preferred embodiment of the present invention: a) the elevator is closed in a leveling zone, if the personnel in the elevator car do not have a door opening instruction, the instruction of stopping the floor inside and outside the elevator car is cancelled to directly drive to the base station, if the personnel in the elevator car continuously press the door opening instruction, the door is opened, otherwise, the door is closed, if the door is opened, the anti-door closing device fails, the door is closed, and then the elevator is directly driven to the base station;
b) when the elevator is driven away from the base station, stopping the elevator in the same direction and nearby without opening the door, and at the moment, rapidly and reversely driving the elevator to the base station directly without an in-car door opening instruction;
c) the elevator is driving to the base station, and immediately driving to the base station without stopping on the floor in the midway;
d) the elevator is opened immediately at the base station, and then is closed immediately after the door is opened for 15s, and the elevator does not accept any instruction except that the door opening instruction in the elevator car is accepted at the moment.
The invention realizes the following beneficial effects:
the fire switch can be controlled by a fire fighter and can also be remotely controlled by an elevator control system in a duty room, so that the fire fighter can conveniently carry out fire rescue tasks in time, the personal safety of passengers is effectively guaranteed, and meanwhile, when the elevator is positioned at different positions, the elevator has corresponding operation specifications, so that the safety performance is greatly improved.
