中文摘要:为了检验智慧工厂信息采集节点的上线率、组网耗时、轮询耗时、中继深度和组网稳定性等组网能力指标,为工业信息采集节点的研发、测试提供参考依据,设计了一种组网能力测试平台。该平台采用电磁兼容性良好的铝制组网单元作为信息采集节点从节点的测试载体,可为从节点提供工作电压和信号耦合通信渠道。采用“高频+低频+高频”组合电源滤波器,能够有效滤除120KHz~40MHz干扰信号,可为测试平台提供相对纯净的测试环境,保障测试平台的稳定性和测试数据可靠性。试验结果证明:建设的测试平台性能稳定、功能齐全,可为电力线通信产品的组网能力测试提供有力的数据参考。

Design of intelligent factory information collection node networking capability test platform
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.
