Problems solved by technology

[0004] However, the existing on-line detection methods for braking distances mainly rely on sensor detection, and encoders or Hall sensors need to be installed on the shaft end of the equipment motor, or the low-speed shaft end, or the brake wheel, resulting in complex installation and debugging and high implementation costs. , Difficulty in post-maintenance and other issues have great limitations in practical application and promotion

Abstract

The application discloses a detection method and device for a braking distance. The detection method includes: obtaining the stator voltage curve from the beginning of the braking process to the end of the braking; and obtaining the braking distance according to the number of characteristic points of the stator voltage curve. This detection method calculates the braking distance of the working device by collecting the stator voltage curve, which is suitable for real-time online measurement of the braking distance. It only needs to collect the stator voltage of the motor and analyze, calculate and process it to obtain the braking distance without additional installation Devices such as sensors have many advantages such as low implementation cost, simple installation, convenient wiring, and convenient maintenance.

Description

technical field [0001] The present invention relates to the technical field of brakes, and more specifically, to a detection method and device for a braking distance. Background technique [0002] Brakes are devices that have the functions of decelerating, stopping or keeping a moving part (or moving machinery) in a stopped state, and are widely used in industrial equipment such as cranes, elevators, and construction lifting machinery. The performance state of the brake directly affects the safety of equipment operation. The measurement of the braking distance is of great significance for evaluating the performance of the brake, ensuring the safety of equipment operation, and preventing safety accidents. [0003] At present, the measurement methods of the braking distance are mainly divided into two categories: one is the direct measurement method, and the other is the indirect measurement method. The direct measurement method uses various detection instruments (such as mea...
