The invention provides an ATS system key redundant equipment main and standby machine abnormity detection method, the key redundant equipment in the ATS system comprises an A machine and a B machine which are mutually redundant, and the method comprises the following steps: obtaining states of the A machine and the B machine in real time; judging whether the state of the machine A and the state of the machine B meet a preset abnormal judgment condition for frequently switching the main and standby states of the main and standby machines or not, and judging whether the state of the machine A and the state of the machine B meet a preset abnormal judgment condition for the main and standby states or not; if the state of the machine A and the state of the machine B meet a preset abnormal judgment condition for frequent switching of the main and standby states of the main and standby machines, it is determined that the frequent switching of the main and standby states of the main and standby machines of the machine A and the machine B is abnormal; and if the states of the A machine and the B machine meet the preset main/standby machine state abnormity judgment condition, determining that the main/standby machine state abnormity occurs in the A machine and the B machine. According to the invention, two faults frequently occurring in the main and standby machines of the key redundant equipment in the ATS system can be monitored, the faults can be found and repaired in time, and fault time delay is reduced.
本发明提供一种ATS系统关键冗余设备主备机异常检测方法,所述ATS系统中的关键冗余设备包括互为冗余的A机和B机,包括以下步骤:实时获取A机和B机的状态;判断A机和B机的状态是否满足预设的主备机频繁切换主备状态异常判定条件,以及,判断A机和B机的状态是否满足预设的主备机状态异常判定条件;如果A机和B机的状态满足预设的主备机频繁切换主备状态异常判定条件,则确定A机和B机出现主备机频繁切换主备状态异常;如果A机和B机的状态满足预设的主备机状态异常判定条件,则确定A机和B机出现主备机状态异常。本发明能够针对ATS系统中关键冗余设备的主备机经常出现的两种故障进行监测,及时发现以及修复故障,减少故障延时。
