利用电力线实现电力设备集中管理技术，因其省时省力，有助于实现电力设备的全程全网监控而受到普遍的欢迎。目前，物理层的通信调制方式已成为研究的热点，从以前的ＦＳＫ（频移键控法）调制方式转向了新一代扩展频谱通信技术，并已取得了很大的进展。因此，数据链路层及网络
The use of power lines to achieve centralized management of power equipment technology, because of its time-saving and labor-saving, help to achieve full network-wide monitoring of power equipment and are generally welcomed. At present, the modulation mode of communication at the physical layer has become a research hotspot. From the previous FSK (Frequency Shift Keying) modulation method to a new generation of spread spectrum communication technology, great progress has been made. Therefore, the data link layer and network
