An intelligent control system for double brakes with early warning function

Abstract

The present invention proposes an intelligent control system for double brakes with an early warning function, including: an elevator intelligent main control module, a driver, a left brake control circuit module, a right brake control circuit module, a brake module, a traction machine, a remote monitoring module, SMS notification module, intelligent weighing device and intelligent service platform. The advantages of the present invention are: the brakes on both sides of the traction machine can be controlled separately, and the brake force on both sides can be detected separately. According to the detection result of the brake force, the intelligent main control module of the elevator can realize the control of the elevator by collecting the data of the intelligent weighing device. Intelligent load adjustment function; at the same time, the elevator intelligent main control module, remote monitoring module, warning device, intelligent weighing device and intelligent service platform cooperate to realize the early warning function.

Description

technical field [0001] The invention belongs to the technical field of elevator control, in particular to an intelligent control system for double brakes with an early warning function. Background technique [0002] At present, the elevator brake control mode in the industry adopts a single-way brake control mode, that is, the brakes on both sides of the traction sheave of the main engine use a one-way control mode, which can only enable the brakes on both sides to be opened at the same time. Closed, the function of opening the brake on one side alone cannot be realized. At the same time, the current detection method for the brake force on both sides of the elevator traction sheave in the industry is to detect when the brakes on both sides are closed at the same time, and it is impossible to effectively detect the brake force on one side; it is also impossible to realize when the brake When the force is close to the point where the load overcomes the static friction, an ear...

Problems solved by technology

[0002] At present, the elevator brake control mode in the industry adopts a single-way brake control mode, that is, the brakes on both sides of the traction sheave of the main engine use a one-way control mode, which can only enable the brakes on both sides to be opened at the same time. Closed, unable to realize the function of opening the brake on one side alone

At the same time, the current detection method for the brake force on both sides of the elevator traction sheave in the industry is to detect when the brakes on both sides are closed at the same time, and it is impossible to effectively detect the brake force on one side; it is also impossible to realize when the brake When the force is close to the point where the load overcomes the static friction force, an early warning is made

[0003] Therefore, the current control mode will inevitably lead to certain defects: for example, only when there is a problem with the brake force on both sides can it be recognized and judged as a fault by the system; , once the brake force on both sides is insufficient, the elevator will uncontrollably tilt to the heavier side, which is prone to casualties of passengers or maintenance personnel; when the brakes on both sides are controlled at the same time, due to mechanical or electromagnetic reasons As a result, the suction and release of the brakes on both sides are not synchronized, which may easily cause the elevator to start shaking and release secondary noise when the brakes stop.
