Research on Power Line Communication Path Search under the Background of New Energy Access

The power line communication detection device is the core equipment of the low-carbon building energy Internet. Although the power line carrier communication (HPLC) adopted by it has a fast transmission speed, its path search signaling communication reliability is low, which seriously restricts the communication performance of the relay. The two-way automatic communication system (TWACS) has high reliability, but its path search speed is slow, which seriously affects the timeliness of communication. In order to improve the coverage and reliability of power line communication detection device in energy Internet information perception, an improved multi-mode fusion communication path search algorithm based on HPLC and TWACS is proposed. The algorithm uses TWACS as the path search signaling of PLC downlink communication, uses PLC to transmit main data information, and uses TWACS to transmit broadcast information and path relay instructions
