Abstract

The invention discloses a test method and a test device for a communication module of an intelligent electric energy meter. The test method includes the following steps: performing a ripple test on the communication module of the smart electric energy meter; building a load test network of the communication module, and then carrying out a load capacity test on the communication module through the load test network; building a power-on and power-off test of the communication module Network, power on and off test the communication module; test the communication capability of the meter under test in extreme environments; test the power consumption of the smart power meter to determine the maximum dynamic power consumption and maximum static power consumption of the smart power meter. The present invention can simulate the influence of various environments on the communication module, so that the communication module with poor communication success rate and test data can be processed, and the actual communication success rate and stability of the communication module of the electric energy meter are improved. Table data collection and interaction provide guarantees, and the data of these tests are helpful for the development and improvement of hardware circuits.

Description

technical field [0001] The invention relates to a test method in the technical field of electric energy meters, in particular to a test method for a communication module of an intelligent electric energy meter, and also to a test device for a communication module of an intelligent electric energy meter using the method. Background technique [0002] With the development of my country's smart grid, smart energy metering equipment has been widely used in the field of energy metering. In order to solve the problems of slow transmission efficiency, small amount of information, short coverage distance, susceptibility to interference, and prone to packet loss in the transmission process of traditional narrowband modules, an in-depth application of smart meters based on HPLC communication modules is proposed. This application taps the potential of smart meters in real-time reporting of low-voltage customer power-off and power-on meters, low-voltage customer voltage and current high...
