Embodiment Construction

[0025] Such as figure 1 , image 3 Shown, a kind of elevator intelligent braking control method comprises the following steps:

[0026] Start the brake control system, the brake control system outputs voltage to the brake coil to separate the brake shoe from the brake wheel, input the target layer information to the brake control system, and the car starts to run;

[0027] When the distance between the car and the destination floor reaches the set distance, the brake control system will slowly reduce the output voltage, the magnetic force generated by the brake coil will gradually decrease, and the compression spring on the brake arm will gradually reduce the brake shoe and braking force. the distance between the wheels;

[0028] When the car reaches the destination floor, the output voltage of the brake control system is cut off, the brake shoes hold the brake wheels tightly, and the car stops running.

[0029] Before the car runs, it also includes the self-learning steps ...

Abstract

The invention discloses an elevator intelligent brake control method and device. The control method includes: a brake control system which outputs voltage to a brake coil to allow a brake shoe to be separated form a brake wheel is started, and target floor information is input to the brake control system to allow an elevator car to operate; when the distance between the elevator car and the target floor reaches the preset distance, the brake control system slowly reduces voltage output, magnetic force generated by the brake coil reduces gradually, and a compression spring on the brake arm gradually reduces the distance between the brake shoe and the brake wheel; when the elevator car reaches the target floor, voltage output by the brake control system is cut off, the brake shoe tightly holds the brake wheel, and the elevator car stops operating. By the method, brake time during elevator stopping is reduced, and safety hazards such as sliding when the elevator control system fails. Due to the fact that the distance between the brake shoe and the brake wheel is reduced, noise caused by collision of the brake shoe and the brake wheel is reduced. The invention further provides an elevator intelligent brake control device.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator intelligent braking control method and device. Background technique [0002] In the elevator industry, in general, the working method of the brake to brake the car is mainly: when the power of the brake is directly applied to the brake coil, a magnetic force is generated to push the compressed spring, so that the brake shoe is separated from the brake wheel, and the brake The gap between the shoe and the brake wheel is fixed. When the car reaches the destination floor, the power supply voltage of the brake coil is disconnected, the magnetic force generated by the brake coil disappears, and the brake shoe is pressed against the brake wheel by compressing the spring, so that the car stops moving, but this braking method, During the contact process between the brake shoe and the brake wheel, the noise is very loud, and the brake may not be closed in time, which may easily cause...
