A method of searching for the root cause of signal equipment faults in a centralized signal monitoring system

Abstract

The invention relates to a signal appliance fault source searching method for a signal central monitoring system. The signal appliance fault source searching method comprises the following steps that firstly, a key signal appliance fault source searching knowledge base is established; secondly, a fault source searching method is defined, the signal appliance warning information can be divided into three classes according to the linkage mode and can be divided into four classes according to the influence ways, and a source searching analyzing result is comprehensively controlled according to time parameters; thirdly, a fault source searching rule is converted, namely, a logical fault source searching rule is converted into a fault source searching information rule list; fourthly, the dynamic detecting judgment of a fault warning buffer pool is carried out, namely, a warning storage buffer pool is established, the dynamical warning source analysis is achieved through the fault source searching information rule list, and a warning result with the relation expression capability is finally formed through a plurality of related warning basis relevance modes; fifthly, the source warning is shown, and the fault analyzing method is refined. Compared with the prior art, the signal appliance fault source searching method has the advantage that the warning quality and the effectiveness are improved.

Description

technical field [0001] The invention relates to a method for searching the fault root of a signal equipment, in particular to a method for searching the fault root of a signal equipment used in a centralized signal monitoring system. Background technique [0002] The alarm root cause analysis is an alarm extension and enhancement function of the centralized signal monitoring system. The validity and accuracy of the alarms of the centralized signal monitoring system, including finding the root cause alarm in the correlation alarm, and automatically constructing the alarm logic correlation link, etc., all depend on the alarm. Root search method. [0003] In the traditional centralized signal monitoring system, only the alarm and display of single type of alarm information can be realized. Since there is no correlation between the alarms, the correlation analysis between the alarms cannot be effectively realized for the related alarms. All alarm information can be displayed un...

Problems solved by technology

[0003] In the traditional signal centralized monitoring system, only the alarm and display of a single type of alarm information can be realized. Since there is no correlation between the alarms, the correlation analysis between the alarms cannot be effectively realized for the related alarms, so only All alarm information can be displayed uniformly at the same alarm display level, and the actual cause and severity of the alarm cannot be effectively distinguished, which affects the maintenance efficiency and processing time of maintenance personnel
