摘要
为了及时发现守时主系统运行中出现故障概率最高的设备,降低比对数据的出错率,提高守时精度及比对数据的可靠性和完整性,设计了一种守时设备故障的自动诊断和报警系统。该系统采用专家系统故障诊断方法,通过对守时比对系统的时间比对数据的实时监测和分析,发现比对数据异常,及时启动故障自动诊断系统,通过报警系统报告发生故障的可能设备,实现故障的及时发现和尽快排除。结果表明,该守时设备故障的自动诊断和报警系统达到了预期目标。
An automatic diagnosis and alarm system for the malfunction of the time keeping devices has been designed to detect the equipments timely, which are the most likely to be failure in the running main time keeping system, to reduce the error probability of the comparison data, and to improve the precision of time keeping and the reliability and integrality of data. The automatic diagnosis and alarm system in which the expert system fault diagnosis is adapted detects the abnormality of comparison data by monitoring in real time and analyzing the time comparison data in time keeping system, then starts the automatic diagnosis system in time, and reports the probable failed device by the alarm system, so that the malfunction can be detected immediately and eliminated as early as possible. The results show that this automatic diagnosis and alarm system has achieved the expected objective.
