中文摘要:当前通信终端普遍存在通信不稳定性、可靠性低以及抗干扰性弱等问题,为此设计基于北斗卫星导航技术的配电自动化通信终端。首先设计配电自动化通信终端总体架构,并设计配电自动化通信终端载体,然后设计配电自动化通信终端运行主程序,在北斗控制单元中编写信息传入速率控制程序,调控终端功率大小,实现信号传入速率控制,采用射频信号处理程序对射频信号实施滤波和放大处理。结果表明:配电自动化通信终端应用下,通信收发损失程度均在5以下,信噪比均大于10,说明该终端的通信可靠性较高、通信抗干扰性较强。

Design of distribution automation communication terminal based on Beidou satellite navigation technology
Abstract:In order to accurately detect the illegal intrusion in distribution network, a method of illegal intrusion detection in distribution network based on network behavior sniffing is designed. The sniffing technology is used to collect the data packets of illegal intrusion in distribution network, and the non negative matrix decomposition algorithm is used to reduce the dimension of sniffing data packets. The multi-agent method is used to design the illegal intrusion detection algorithm of distribution network, and the illegal intrusion detection of distribution network is realized according to the similarity of feature vectors. The test results show that the average similarity of feature vectors detected in all attack categories of KDDCUP dataset is greater than 0.2356, and only the detection of password intrusion attack is slightly insufficient. In UNSW_ The average similarity of feature vectors detected by NB dataset and attack data dataset is greater than the preset detection threshold, which proves that the design method has strong illegal intrusion detection performance.
