Analysis of Automatic Fault Diagnosis System for Hydraulic Bracket
Under the increasing depth of underground mining,the stent is affected by high load and humid environment,which is prone to more malfunctions,and when applying the traditional manual troubleshooting means,there are problems such as low processing efficiency.For this reason,based on the operation principle of the stent electro-hydraulic system,the fault tree model of the stent electro-hydraulic system will be organised from the hydraulic and electric control aspects.Secondly,the automatic fault diagnosis logic under different faults will be analysed,and an automated fault diagnosis system suitable for hydraulic stent will be proposed,and the composed state acquisition,data fusion and decision-making units will be perfected.Finally,the use of this diagnostic system is analysed,which can significantly reduce the failure rate and fault processing time,and is conducive to ensuring the safety and reliability of underground bracket application.
