A large reducer performance detection system based on multi-sensor fusion

Abstract

The invention provides a large speed reducer performance detecting system based on multi-sensor fusion and relates to the technical field of real-time performance detection of transmission devices using gear drive as a main drive mode. The detecting system comprises a signal acquisition module, a centralized signal storage module and a signal processing module. The signal acquisition module comprises a temperature sensor, a pressure sensor, a Hall sensor, an acceleration sensor and an eddy-type sensor, wherein the sensors are fixed at different positions of a large speed reducer. In addition,the sensors included by the signal acquisition module are in wireless connection with the centralized signal storage module, and then the centralized signal storage module is connected with the signalprocessing module. The large speed reducer performance detecting system based on multi-sensor fusion can effectively predict the service life of larger speed reducers and accurately judge the fault occurrence causes of the large speed reducers and even can accurately diagnose the specific positions of fault occurrence.

Description

technical field [0001] The invention relates to the technical field of real-time performance detection of a transmission device with gear transmission as the main transmission mode, in particular to a large-scale reducer performance detection system based on multi-sensor fusion. Background technique [0002] The reducer is an independent closed transmission device between the prime mover and the working machine, which is used to reduce the speed or increase the torque to meet the working needs. The stability of the reducer is very important to the entire mechanical equipment, especially for the large reducer used in the coal mining field, it plays an important role in the coal mining process. Once a failure occurs, its performance will be seriously affected. If it is not discovered in time, when the failure occurs, it will cause huge economic losses and even threaten the lives of operators. Therefore, the real-time monitoring of the working status of the reducer is particul...

Problems solved by technology

However, at this stage, there is no mature, timely, accurate, and effective method for detecting the working status of the reducer. At present, it is generally used to check the reducer for possible faults through regular or irregular manual inspections. This type of detection method Most of them are human-made observations and investigations. In many cases, the problems of the reducer cannot be accurately found, and there are great hidden dangers.
