摘　　要：工频通信系统上行信号故障会导致电力线路载波通信能力下降、电网全面瘫痪,为了提高工频通信系统上行信号的传输效率,降低由于上行信号通信故障所导致的电网信号传送停滞问题,提出基于差分技术的工频通信系统上行信号自动化检测的方法,该方法采用PLCC通讯方案采集工频通信系统上行信号,再利用差分技术提取工频通信系统上行信号特征,最后将已提取的工频通信系统上行信号特征输入以SVM为框架,结合GSSK-VLC系统所组建的分类器中,根据分类器输出结果实现工频通信系统上行信号的自动化检测。实验结果表明,所提方法检测成功率高、运算量少。In order to improve the transmission efficiency of the uplink signal of the power frequency communication sys-tem and reduce the problem of grid signal transmission stagnation caused by the communication failure of the uplink signal,An automatic detection method for uplink signal of power frequency communication system based on differential technology is proposed.The PLCC communication scheme is adopted to collect the uplink signal of the power frequency communication sys-tem,then the differential technology is used to extract the characteristics of the uplink signal of the power frequency communi-cation system,and finally uploads the extracted power frequency communication system uplink signal.The signal feature input takes the SVM as the frame,and in the classifier formed by the GSSK-VLC system,the automatic detection of the uplink sig-nal of the power frequency communication system is realized according to the output result of the classifier.The experimental results show that the proposed method has a high detection success rate and a small amount of computation.
