Intelligent positioning method for judging anomalous position of protection channel with fusion of multiple source information

A method of carrying out fault attribution according to information fusion technology and historical operation data is used, the invention provides a method for judging the abnormality of a protectionchannel with the fusion of multiple source system data information, and the fast and accurate positioning of a failed component in the time that the protection channel is abnormal is achieved. The main idea of the method is that the alarm information of a protection information system and a communication real-time operation system which monitor dynamic operation of a secondary loop is fused, atthe same time, a static storage protection channel, a protection channel management system of communication channel position information and data information of a communication resource management and control system are used, and through building a protection channel abnormality judgment model and using cross-inference among the multiple pieces of source information, the accurate judgment of thefailed component in the time that the protection channel is abnormal is achieved is realized. According to the abnormality judgment proposed by the present invention, whether a failure belongs to a protection device failure or a communication channel failure can be judged, and a specific failed device can be accurately judged.
