Abstract

The invention relates to the field of ammeter performance testing and particularly discloses an intelligent ammeter communication receiving performance testing system and a method. The method comprises that an upper computer sends a data package order to control a copy controller and a frequency generator; the data package order sent by the upper computer is analyzed by the copy controller according to a frequency clock generated by the frequency generator and is sent to an intelligent ammeter to be tested; the intelligent ammeter to be tested makes response after receiving the correct data package order and reversely returns response data to the upper computer; and the upper computer and analysis software running inside of the upper computer analyze the response data sent by the intelligent ammeter to be tested so as to judge receiving performance of the intelligent ammeter to be tested. According to the intelligent ammeter communication receiving performance testing system and the method, the receiving performance in center frequency deviation of the intelligent ammeter can be tested and implement is simple and convenient.

Description

technical field [0001] The invention relates to the field of performance testing of electric energy meters, in particular to a test system and method for evaluating the receiving performance of an intelligent electric energy meter with a remote communication module. Background technique [0002] With the large-scale promotion and application of smart energy meters in China's State Grid and China Southern Power Grid, a large number of smart energy meters with communication modules are connected to the grid. For smart energy meters with communication capabilities, it is necessary to perform performance tests on their communication modules. However, the communication modules currently operating in the market are provided by many manufacturers. The reason is that both the modulation method and the coding method are kept secret, which brings difficulties to the receiving performance test of the smart energy meter. [0003] Conventional communication equipment reception performan...
