Embodiment approach

[0060] Taking the most common "no communication between the collection system and the terminal" in the collection operation and maintenance process as an example, the collection system found that the smart energy meter corresponding to the user associated with a certain collection terminal failed to collect electricity consumption information after performing the collection task. After checking by the operation and maintenance monitoring personnel, it was found that the terminal had not communicated with the main station for 24 hours. The system defined it as the terminal being offline for the lack of communication between the acquisition system and the terminal. For the abnormality that the acquisition system found that the terminal had not been online for more than one day, defined Possible causes of failures and their priority order of diagnosis. Remote diagnosis includes: pre-acquisition failure, main station terminal file error, on-site failure diagnosis includes: terminal ...

Abstract

The invention discloses a method for fault diagnosis and analysis of an electricity utilization information acquisition system, which comprises the following steps: establishing an abnormal fault library of the electricity utilization information acquisition system, and setting corresponding relationships between various parameters in the abnormal fault library, wherein the parameters include: anomalies, abnormality causes, diagnosis methods and repair plans; obtaining at least one abnormal cause according to anomalies and utilizing the corresponding relationships between the anomalies and the abnormality causes; obtaining the corresponding diagnosis method of each abnormality cause by utilizing the corresponding relationships between each abnormality cause and the diagnostic method, confirming the abnormality causes by utilizing the diagnosis method to diagnose the fault of the electric information acquisition system; obtaining the repair plans according to the corresponding relationship between the abnormality causes and the repair plans to repair the fault of the electric information acquisition system. The method effectively reduces the quality requirements of operation and maintenance personnel for collecting electricity utilization information, improves the operation and maintenance efficiency, and reduces the problem that tahe fault cannot be repaired due to insufficient personnel capacity.

Description

technical field [0001] The present invention relates to the field of operation and maintenance of an electricity consumption information collection system, and more specifically, relates to a method and system for fault diagnosis and analysis of an electricity consumption information collection system. Background technique [0002] The power consumption information collection system is an important part and technical support of the State Grid Corporation of China to build a smart grid. It realizes data collection, data management, and electric energy through the physical link and information system composed of software and hardware such as the main station, communication channels, and collection equipment.
