Problems solved by technology

[0003] The existing fire switch can only be manually operated by firefighters. When it is necessary to trigger the fire protection state of the elevator, this function cannot be realized in the duty room. The return system cannot guarantee the operation and control of elevators in different positions, which increases the safety factor of users

Embodiment

[0025] refer to Figure 1-2 , the fire return system and method of use thereof, including a fire switch for sending a fire emergency return command, and when the elevator receives the fire emergency return command sent by the fire switch, the following steps are specifically performed:

[0026] (1) All hall call commands, car running commands and registered running commands are cancelled;

[0027] (2) The door opening system and emergency system installed in the car keep working, and the reverse door opening system stops working;

[0028] (3) The elevator immediately leaves the group control or parallel control and performs the emergency return work alone;

[0029] (4) The fire emergency return command cannot give priority to the maintenance control state and the emergency electric control state, nor can it cut off the operating state of the two, and the sound signals in the elevator machine room and the car will sound immediately until the inspection or emergency electric co...

Abstract

The invention discloses a fire-fighting return system and an application method thereof. The fire-fighting return system comprises a fire-fighting switch used for sending a fire-fighting emergency return instruction. When an elevator receives the fire-fighting emergency return instruction sent by the fire-fighting switch, the following steps are specifically executed, wherein elevator calling instructions and in-car running instructions of all elevator halls and registered running instructions are all cancelled; a door opening system and an emergency system arranged in a car keep working, anda reverse door opening system stops working; the elevator immediately breaks away from group control or parallel control, and the emergency return work is independently executed; the fire-righting emergency return instruction cannot preferentially maintain 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 an elevator machine room and audible signals in the car immediately ring till the maintenance or emergency electric control state is cancelled; the elevator machine room and a shaftway illumination system are automatically opened; and when the elevator is at different positions, different steps are executed for running. By means of the fire-fighting return system, fire-fighting efficiency is improved, and the personal safety of the masses in buildings is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of elevator fire protection, in particular to a fire protection return system and a use method thereof. Background technique [0002] With the wide application of elevators in daily life, the control of elevators in special situations has also received widespread attention, especially in fires. If elevators can provide better control methods, it can effectively improve rescue efficiency and reduce fire losses. . [0003] The existing fire switch can only be manually operated by firefighters. When it is necessary to trigger the fire protection state of the elevator, this function cannot be realized in the duty room. The return system cannot guarantee the operation and control of the elevators in different positions, which increases the safety factor of the user. Contents of the invention [0004] Purpose of the invention: In order to solve the deficiencies in the background technology, the present inventi...
