Method for preventing elevator from sudden power outage and auxiliary power supply system

Abstract

The invention discloses a method for preventing an elevator from sudden power outage and an auxiliary power supply system. The auxiliary power supply system comprises an auxiliary power supply switch (1), an auxiliary power supply battery (2) and an auxiliary controller (3), wherein the auxiliary power supply battery (2), the auxiliary controller (3) and the auxiliary power supply switch (1) are serially connected in turn through a wires and then are in parallel connection with a main elevator power supply system (5); the main elevator power supply system (5) comprises an elevator control device (6) and a motor (7); the motor (7) is connected with a cage (8) through a rope; and the auxiliary controller (3) is connected with the elevator control device (6) through a data line. The method and the auxiliary power supply system can keep the elevator running under a power outage condition and can effectively prevent people in the elevator from being trapped.

Description

technical field [0001] The invention relates to a method for preventing sudden power failure of an elevator and an auxiliary power supply system, belonging to the field of elevators. Background technique [0002] With the development of society, more and more people have moved into buildings from bungalows. Due to the high height of buildings, elevators are usually equipped. Almost everyone who lives in a building has encountered a sudden power outage. Although most high-rise buildings equipped with elevators have their own generators, the generators require staff to start up after a power outage, and it takes a certain amount of time. If there is a sudden power failure, the elevator will immediately cut off the power, and the people in the elevator will be trapped in the elevator, and they will not be able to leave the elevator until the staff starts the generator. Because the elevator is dark after the elevator power failure, this will cause some people on the elevator Pa...

Almost everyone who lives in a building has encountered a sudden power outage. Although most high-rise buildings equipped with elevators have their own generators, the generators require staff to start up after a power outage, and it takes a certain amount of time. If there is a sudden power failure, the elevator will immediately cut off the power, and the people in the elevator will be trapped in the elevator, and they will not be able to leave the elevator until the staff starts the generator. Because the elevator is dark after the elevator power failure, this will cause some people on the elevator panic, if people suffering from mental disorders may also get sick, in the prior art, there is really no good solution to the problem of sudden power failure of the elevator
