Abstract

The invention discloses a gateway meter assessment device. The gateway meter assessment device comprises an analog acquisition module, a gateway meter communication module and a CPU; power network electrical parameters are collected by the analog acquisition module, the gateway meter communication module obtains internal collection power network electrical parameters of a gateway meter, the CPU conducts data statistics and contrastive analysis on the power network electrical parameters collected by the analog acquisition module and the internal collection power network electrical parameters of the gateway meter, online testing and state assessment are carried out on the gateway meter according to statistical data and contrastive analysis results, and an alarm is given for abnormal conditions. The gateway meter assessment device is low in cost, convenient to install and simple in operation maintenance; data such as the voltage, the current, the power and the electric quantity of the device can be detected and metered on line; real-time online error detection and alarming, voltage secondary voltage drop testing and current and voltage secondary load testing can be carried out on the gateway meter, and an existing manual patrolling mode is substituted.

Description

technical field [0001] The invention relates to a metering device monitoring device, in particular to a gateway meter evaluation device. Background technique [0002] The gateway meter is used for billing or assessment of electric energy metering equipment between countries, between regional power grids, between provincial power grids, between regional power grids, power generation companies accessing the Internet, and large enterprise users. In order to ensure the accuracy of measurement, The equipment needs to be inspected and verified regularly. Now the commonly used method is to carry special inspection equipment to the site for inspection periodically, which requires a lot of manpower and expense, and the inspection workload is heavy. The work process is cumbersome and complicated, and the cycle is long. It is impossible to effectively monitor and manage numerous gateway meters, and it is difficult to get timely feedback on the alarm information when the equipment fails...
