A Redundancy System Synchronization and Monitoring Judgment Method

Abstract

The present invention provides a synchronization and monitoring judgment method for redundant systems. The method includes the following steps that: an input device A sends an input instruction 1 to asystem A and a redundant system B, and an input device B sends an input instruction 2 to the system A and the redundant system B; the system A and the redundant system B periodically send heartbeat messages of the their respective local side systems to opposite-side systems, whether the opposite-side systems are in normal states is judged according to judgment on whether the heartbeat informationis received or not; and the system A and the redundant system B send the output parameters of time stamps of the their respective local side systems to the opposite-side systems, and the local-side systems judges the output parameters of the local side and the output parameters of the opposite-side system, so that the states of each system or each parameter can be obtained. The method provided bythe invention can monitor the output of redundant systems and can monitor the running statuses of opposite-sides system in real time, so that system users can conveniently process or respond to the faults of the systems.

Description

technical field [0001] The invention belongs to the field of redundant system design, in particular to a redundant system synchronization and monitoring judgment method. Background technique [0002] At present, redundant systems mostly use equipment with similarity redundancy. As long as one of the equipment fails and the system fails, it is very likely that the other redundancy system will also fail due to the same problem, and the reliability of the system cannot be performed well. Assure. At the same time, because the operation status of the opposite system is not supervised, only the operation status of the local system is paid attention to, so that the users of the system on one side cannot make timely processing or early warning of system failures and other situations. Contents of the invention [0003] The object of the present invention is to provide a redundant system synchronization and monitoring judgment method, which overcomes or alleviates at least one of t...
