Research on fault early warning method for key sensorsof electro-hydraulic control system

In order to ensure the normal operation of the electro-hydraulic control system,the fault early warning of the core sensor components of the electro-hydraulic control system was a key link.The working principle of the sensor in the electro-hydraulic control system was analyzed,and the fault law of the sensor in the system was obtained.In order to early-warning and diagnosis the fault of the core sensor in the underground electro-hydraulic control system,combined with the current popular sensor fault early warning method,a diagnosis method combining static analysis and dynamic analysis was proposed by taking the pressure sensor of the hydraulic support as an example.The method’s core was to analyze the data collected by the sensor,so as to effectively predict the fault of the pressure sensor and promote the reliable and efficient operation of the electro-hydraulic control system.
