Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, first read all the data acquisition servers and data acquisition channel information of the distributed data acquisition of the dispatching automation system from the database, and then collect the IEC104 protocol data acquisition communication status information in the dispatching automation system in real time, including IP address status and network port status and IEC104 communication link status, once a fault occurs in it, the corresponding fault processing plan will be retrieved from the data collection fault logic reasoning rule base; various status information of distributed data collection applications in the scheduling automation system will be collected in real time, including data collection Various hardware status such as server hard disk space, CPU, and memory usage, data acquisition server application software ...

Abstract

The invention relates to an intelligent diagnosis method for a distributed data acquisition fault of a dispatching automation system. The intelligent diagnosis method comprises the following steps: (1) a data acquisition fault logical reasoning rule base is established in the dispatching automation system; (2) IEC104 stipulation data acquisition and communication state messages are collected in real time; (3) various state messages used for distributed data acquisition in the dispatching automation system are collected in real time; (4) the various states are stored in a database, and once a fault happens, the fault phenomenon is immediately matched in the data acquisition fault logical reasoning rule base, and corresponding fault handling methods are displayed on an interface for the reference of system maintenance personnel. By means of the intelligent diagnosis method, huge maintenance pressure brought by the operation mode of distributed data acquisition of the dispatching automation system is removed, the requirements of users for efficient maintenance of the distributed data acquisition of the dispatching automation system are met, the dispatching automation system maintenance personnel can be helped to position the data acquisition fault quickly and eliminate the fault quickly, therefore, the reliability of the dispatching automation system is improved, and the dispatching automation system is easy to maintain and convenient to operate.

Description

technical field [0001] The invention relates to an intelligent fault diagnosis method for distributed data collection in a dispatching automation system, which is used in a dispatching automation system adopting distributed data collection to collect various states of distributed data collection in real time. The phenomenon searches for a corresponding fault handling method and shortens the recovery time of system data collection faults, and belongs to the technical field of power dispatching automation. Background technique [0002] At present, it is more and more common to use distributed data collection in the data collection of dispatching automation system. The advantage of distributed data collection is that all data collection tasks of dispatching automation system are distributed in multiple areas, which effectively reduces the cost per The operating load of a data acquisition server improves the impact resistance of the system in emergencies. But what follows is th...
