Research on fault diagnosis of HT-60 drilling rig based on neural network expert system

Combining the characteristics of drilling rig fault, a solution of fault diagnosis expert system based on artificial neural network is proposeed. The fault diagnosis system is designed for HT-60 drilling rig, which acquires knowledge by neural network and diagnoses by expert system. The system with characteristics of self-learning and self-adaptive can acquire knowledge from existing data in order to achieve the purpose of expanding knowledge, which maks up the inadequacies of traditional expert system. Through analyzing a variety of common faults and solutions, the software interface is established by using the Force Control software to achieve fault diagnosis which is based on artificial neural network expert system.
