The power carrier communication signal has attenuation in the transmission process.In order to reduce the transmission error rate of power carrier communication and monitor the signal transmission behavior in real time,a power carrier communication signal monitoring system based on multi parameter identification is designed.According to the value range of dynamic forgetting factor,a multi parameter identification mechanism is established,and then the related carrier communication data is combined to solve the signal attenuation parameters to complete the feasibility analysis of power carrier communication.According to the layout form of the overall architecture of the carrier communication system,determine the connection position of the filter and coupler elements,and complete the design of power carrier communication signal monitoring system.The experimental results show that the maximum transmission error rate of power carrier communication is only 23.5%,under the action of multi parameter identification mechanism,which has outstanding application value in real-time monitoring signal transmission behavior.
