Power line carrier communication system and method for optimizing coverage area

The invention discloses a power line carrier communication system and method for optimizing a coverage area. Power line carrier communication with strong anti-interference capability and wide communication range coverage is realized. The system comprises a relay and a terminal. The relay is installed on a power line and used for receiving terminal signals and sending signals to the terminal, the relay is configured to judge the distance between the terminal and the relay according to the communication time, and the relay is configured to conduct frequency hopping communication with the terminal according to the distance between the terminal and the relay. 优化覆盖范围的电力载波通讯系统和方法，实现抗干扰能力强，通讯范围覆盖广的电力载波通讯，包括：中继器和终端，中继器安装在电力线上，中继器用于接收终端信号以及向终端发送信号，中继器配置为根据通讯时间判断终端与自身的距离，中继器配置为根据终端与自身的距离与终端进行跳频通讯。
