Research on Test System of Signal Interference Resistance of Power Communication Carrier Channel

In view of the current low-reliability and low accuracy of power line carrier communication performance test equipment in the anti-interference performance test, the article deeply analyzes the technical implementation of the test system and the key technology requirements of anti-interference test. The electromagnetic conduction and radiated crosstalk and its multipath interference existing in the test system frame structure are studied, and the communication performance test system of the point-to-point carrier communication module is designed in the low-voltage power line channel environment. The test system has a simple structure and strong practicability. It can realize point-to-point communication error rate test and effective communication rate test, and can comprehensively evaluate the performance of the communication module according to the test result, and can horizontally compare the communication performance of the carrier communication modules of different manufacturers. The communication performance of different types of carrier communication units of the same manufacturer can be compared vertically, and the versatility is strong. (paper)
