Design of Nuclear Measuring Instrument Fault Diagnosis System Based on Circuit Characteristic Test

摘要：

The circuits of nuclear measuring instruments are very complicated, and the testing and fault inspection of the nuclear measuring instrument system is difficult. To solve this problem, the fault diagnosis system was designed by combing circuit characteristic test technology with virtual instrument, virtual testing, test data analysis and data management technology. The method based on circuit characteristic test, which is comparing the characteristic curves of tested circuit with the one of the corresponding normal circuit, is applied to the fault diagnosis of nuclear measuring instrument. The fault diagnosis system consists of hardware part and software part. The hardware part includes computer, data acquisition module, arbitrary waveform generator (AWG) module, interface circuit module, electric relay module, etc; the software is made up of computer management software module, control software module and testing functional software module and so on. By the fault diagnosis system, it can test the circuit characteristic of any circuit module of the nuclear measuring instruments, diagnoses and finds out the faulted parts of the nuclear measuring instruments quickly and shows the diagnosing results on the display.
