Development of Remote Hydraulic Expert System

According to the condition characteristics of construction machinery’s hydraulic systerm,a expert system of hydraulic system is designed.The total structure of the expert system is built,and the composing of the knowledge base of that expert system and its inner reason logically the machining are emphasized.The system,which made use of the database of web and the technique characteristics of the web pages,developed well the Internet which accumu-lates,and shares the knowledge,and improved the performance of the expert system of fault diagnosis.The inside of expert system exerted forward reason on the fault diagnosis.This system has applied in some hydraulic system.I t is very valuable to apply this system to practical applications.
