Design of a Fault Diagnosis Equipment

Abstract

Abstract In the process of daily maintenance and repair of a certain type of equipment, there are problems of long fault diagnosis time and untimely repair. A set of fault diagnosis equipment has been developed for this purpose. The device adopts C8051F120 microprocessor and consists of interface circuit board, excitation signal board, single chip computer board, signal conditioning board, fault diagnosis expert system, etc. It can detect the main performance parameters of the tested equipment, and combined with the fault diagnosis expert system, it can realize the function of performance detection, fault diagnosis location and data storage record, and effectively improve the efficiency of fault diagnosis of the tested equipment.
