【Abstract】 In this paper, a research on techniques of microcomputer applications to on line faults monitoring and diagnosis of an indoor tractor was carried out. New techniques, such as CAT (Computer Aided Test), the dynamic analysis of signals, model identification, fault diagnosis, artificial intelligence as well as specialist system are applied to the indoor reliability test of small medium tractors and the analysis of data of the tests. A computer control system of on line state monitoring and fault diagnosis of indoor tractors is developed. Computer is adopted to not only the indoor reliability test of small medium tractors but also the continuous monitoring and record of their running state. Fault judging and analysis are also done by computer. By using computer we are then able to determine the kind, the position, the degree and the cause of the fault. In the meantime, computer forecasts the further going and latent danger of the fault, so that appropriate measure and strategy can be taken. The result of the research shows that the system runs stably and the techniques are advanced. To reliability tests in indoor agricultural machineries, the techniques are both practical and of great economics values.更多还原
