基于工业级4G物联网北斗配电自动化通信技术研究OACSTPCD

Aiming at the problems of low transmission volume and slow speed of distribution automation communication in the process of transportation electricity,cloud edge collaboration mode and device to device(D2D)module are introduced to improve the communication structure between distribution automation equipment based on the industrial 4G Beidou distribution automation communication technology.Firstly,the relay communication network is built with the base station to improve the data transmission speed in the distribution net-work.Then,the security device manager(SDM)algorithm is improved,and the blocking characteristics of the channel are calculated by obtaining the bit error rate of each transmission channel.Finally,the blocking channel is modulated to make the transmission data more cooperative and further improve the transmission speed.The test results show that the maximum amount of communication detected by this system is 48 TB,and the average transmission speed is 10 MB/s,which indicates that this system has high applicability.
