- Abstract
In order to test the network capability indexes of intelligent factory information acquisition nodes, such as on-line rate, networking time-consuming, polling time-consuming, relay depth and networking stability, a networking capability test platform is designed to provide a reference for the research and development of industrial information acquisition nodes. The aluminum network unit with good electromagnetic compatibility is used as the test carrier of the slave node of the information acquisition node, which can provide the slave node with working voltage and signal coupling communication channel. The combination power filter of "high frequency + low frequency + high frequency" can effectively filter out 120 KHz ~ 40 MHz interference signal, and can provide a relatively pure test environment for the test platform, ensure the stability of the test platform and test data reliability. The test results show that the test platform has stable performance and complete functions, which can provide a powerful data reference for the networking capability test of power line communication products.
