Elevator power failure assist system

Abstract

The invention relates to an elevator power failure assist system which comprises a UPS, a power failure detection device, a fire detection device, a fire power failure supplementary subroutine, an ordinary power failure supplementary subroutine, an elevator normal-running main routine and a controller. The elevator power failure assist system is characterized in that power failure detection devicedetects whether power failure occurs and transmits an electric signal to the controller; the fire detection device is connected with a building fire protection system and detects whether a fire occurs and transmits an electric signal to the controller; the controller selects one of the ordinary power failure supplementary subroutine, the fire power failure supplementary subroutine and the elevator normal-running main routine according to the two electric signals; the signal-in three-out UPS continues to supply power to an elevator in the case of power failure; the elevator normal-running mainroutine controls the normal running of the elevator; the ordinary power failure supplementary subroutine controls the elevator to run to the most suitable level by means of the signal-in three-out UPS in the case of ordinary power failure; and the fire power failure supplementary subroutine controls the elevator to run to the first floor in the case of the fire.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to an elevator power failure auxiliary system. Background technique [0002] Along with the continuous development of society, along with the continuous progress of science and technology, the improvement of people's living standard, the application of elevator has been very extensive. Comfort and safety are what every elevator strives for. Because the elevator will encounter a sudden power failure during operation and people or things will be trapped in the elevator, so the elevator power failure emergency device was born. [0003] Today's elevator power failure emergency devices are as compact as a vertical computer host, which can be equipped on domestic or imported elevators. Whether there is a sudden power failure or failure when the elevator is running, the device can automatically switch and take over the "control" of the elevator within a few seconds, allowi...

AI Technical Summary

Problems solved by technology

Whether there is a sudden power failure or failure when the elevator is running, the device can automatically switch and take over the "control" of the elevator within a few seconds, allowing the elevator to run to the preset floor position and automatically open the elevator door to allow passengers to safely Get out of the elevator, but today's elevator power failure emergency device can only run the elevator car slowly in the direction of light load to the leveling floor of the nearest station after the power failure, and it cannot be seamlessly connected. The changes that occur during this process will inevitably cause passengers to panic , especially children, will inevitably form a psychological shadow, and if there is a power outage caused by a fire, and the car is on a high floor, the elevator will leave the passengers on the high floor, thus missing the best time to escape, and the existing elevators Power failure emergency devices are rarely used
