Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] see figure 1 , figure 1 It is a schematic diagram of the circuit structure of the elevator brake control system of the present invention. The elevator brake control system 100 includes an AC input terminal 1, a brake drive module 2 electrically connected to the AC input terminal 1, a brake 3 electrically connected to the brake drive module 2, and a brake drive module connected in series to the The contactor 4 between the AC input terminal 1 and the brake driving module 2, the contactor 4 is composed of two c...

Abstract

The invention provides a control system for an elevator brake. The control system comprises an alternating current input end, a brake driving module and the brake, wherein the brake driving module comprises an EMC circuit, a controllable rectification and alternating current voltage regulation module, a current detection module, an electronic switch, a diode, a voltage stabilizer, an isolation driving module and an MCU circuit. Compared with the prior art, the control system for the elevator brake provided by the invention has the advantages that the electronic switch is arranged in the brake driving module, the electronic switch is controlled to be switched on and switched off according to the fact whether the brake driving module outputs voltage or not, the sliding problem during the elevator sudden stop process is effectively solved, and a contactor does not need to be additionally added.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator brake control system. Background technique [0002] With the leap of electronic science and technology, the elevator technology has been developed rapidly. Among them, the drive technology and control technology have been upgraded through several generations to achieve permanent magnet synchronous speed regulation and computer full intelligent control, which improves the reliability and stability of the whole machine. . However, the brake control circuit (also known as "brake circuit"), which is one of the most important working circuits of the elevator, has always followed the traditional design method. [0003] In recent years, with the sharp increase in the use of elevators, elevator safety accidents are also on the rise, of which brake failures account for about 80%. In addition to mechanical failure, an important reason for brake failure is that the contactor...
