Embodiment Construction

[0018] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] When the excavator is crushing, the pressure data of the main circuit of its hydraulic system will have obvious and regular low-frequency signals, so analyzing its data can determine whether it is crushing. The controller is used to collect the pressure data of the main circuit pressure sensor of the hydraulic system of the excavator, the sampling frequency is 1000Hz, the sampling time is 2s, and a total of 2000 data points are collected. Then, the pressure data is analyzed in the controller through the judgment method of the present invention. If the breaker is working, the pressure data of the main circuit of its hydraulic system will have a pressure waveform when it is broken, and then the result of whether it is in the crushing operation can be ...

Abstract

The invention discloses a method for judging whether a breaker is working based on pressure data. The method analyzes and calculates the pressure data of the main circuit of the hydraulic system of the breaker to determine whether the breaker is working. When the excavator is crushing, the pressure data of the main circuit of the hydraulic system will have obvious and regular low-frequency signals, so analyzing the data can determine whether it is crushing. Compared with the prior art, the method of the present invention can quickly and accurately judge the crushing operation state of the breaker through the analysis of the pressure data of the main circuit of the hydraulic system without installing additional sensors.

Description

technical field [0001] The invention belongs to the technical field of mechanical measurement, and in particular relates to a method for judging whether a breaking hammer works based on pressure data. Background technique [0002] The hydraulic breaker is referred to as "breaker" or "breaker". The power source of the hydraulic breaker is the pressure provided by the excavator, loader or pump station. It can break stones and rocks more effectively during engineering construction and improve work efficiency. The hydraulic breaker has become an important working tool for hydraulic excavators, and some people install the hydraulic breaker on backhoe loaders (also known as two-head busy) or wheel loaders for crushing operations; it can play a role in excavating the foundation of buildings. Clean up floating stones and mud in rock crevices more effectively. The use frequency and strength of the breaker directly affect the maintenance frequency and service life of the excavator. ...
