摘要
为了实现远距离数据传输,获取更高通信质量,提高通信的可靠性和抗毁性,研究了一种中压配电网载波通信的自动中继方法来改进现有的人工固定中继,通过旁听站统计一定时间内接收到主站发送给目的站数据的相关信息并将数据帧转发至目的站,目的站分析对比出最优路径,当主站和目的站不能直接通信时,自动选择最优中继路径进行通信并进行动态更新。给出了算法的流程和具体步骤,使用Matlab对一算例模拟算法的实现过程,给出了各中继路径信息并做出对比分析,画出了多次仿真最优路径号变化图。仿真结果证明该算法简单易行,能有效地实现自动中继。
In order to achieve long distance transmission and improve communication quality, reliability and invulnerability, this paper gives the research of an automatically relay method of medium voltage distribution line carrier communication to improve existing artificial fixed relay. The slave station records the received related information of that the master station sends to the destination station in a certain time, and sends the data to the destination station.The destination station analyzes the data to find the optimal relay path. When the master station and the destination station can not communicate directly, it can automatically select the optimal relay path to communicate and dynamically updated. The algorithm process and specific steps are given. Matlab is used to simulate the algorithm to explain the process by an example. The information of each relay path is given and analyzed. The change map of different optimal path simulation is draw. The simulation results show that the algorithm is simple, can achieve automatic relay effectively.
