Abstract:

In order to ensure the safety of power carrier communication network, a power carrier communication abnormal signal monitoring system based on single chip microcomputer and FPGA is designed. According to the abnormal cause of power carrier communication network, the abnormal signal characteristics are set as the criterion. Under the established power carrier communication network model, the signal acquisition equipment, MCU and FPGA components are installed to collect and process the power carrier communication signals. Through feature extraction and matching of real-time communication signals, the abnormal state of the current signal is determined, and the abnormal signal semaphore and type of signal are calculated. Finally, the monitoring results of abnormal signal of power carrier communication are output in a visual form. Through the system test, the conclusion is drawn: compared with the traditional communication abnormal signal monitoring system, the monitoring error of the communication abnormal semaphore of the optimized design system is reduced by 1.37dBm, and the false detection rate of the type of communication abnormal signal is significantly reduced.
