Abstract

The invention relates to the field of measurement automation terminal fault detection and diagnosis, and specifically discloses a split-type measurement automation terminal fault detection device, which specifically includes an upper computer and a lower computer. The lower computer is responsible for collecting various signals of the measurement automation terminal, and the upper computer is responsible for monitoring Various signals are used for fault detection, which effectively solves the problems of inconvenient operation caused by the small space in the actual terminal installation site and the single function of the existing fault diagnosis tool. It can conveniently and quickly realize on-site interface fault detection, wiring error detection and The three major functions of communication protocol compliance detection have effectively improved the efficiency of fault diagnosis of metering automation terminals.

Description

technical field [0001] The invention belongs to the field of fault detection and diagnosis of metering automation terminals, and in particular relates to a split-type metering automation terminal fault detection device and a detection method thereof. Background technique [0002] As the core component of the smart grid, the metering automation system has been widely implemented and applied, and the corresponding smart meters and power terminals have become an inevitable trend of development. At present, various metering automation terminals can realize real-time execution of data collection, terminal parameter search, remote meter reading, terminal parameter setting, power protection function, alarm function, elimination function, data transmission and user information confirmation and other functions. But at the same time, the on-site real-time terminal troubleshooting and troubleshooting tasks brought to the relevant personnel also increased sharply. In particular, the met...
