摘　　要：传统系统将非正常信号全部归为异常类信号或将非正常信号全部归为正常信号,无法实现对多种信号的调控,导致系统安全性较低,为了避免该问题的产生,提出了抵御网络危险信号的自适应调控系统设计。根据硬件总体结构设计数据包过滤模块,使入侵信号转换为正弦波信号,在天线和接收机之间安装识别装置,保证各阵元接收的正弦波信号都是具有幅度增益的,经过变频电路降幅处理,避免短路情况发生。采用型号为S3C2440a处理芯片对变频后的信号进行闭环调控,根据自适应定理对危险信号进行定位,采取“0”或“1”危险信号控制字可获取抵御得益,由此完成自适应调控系统设计。通过实验对比结果可知,该系统最高调控效率可达到95%,保证系统具有安全信号传输能力。Traditional systems categorize abnormal signals as abnormal signals or abnormal signals as normal signals,which can not control many kinds of signals,resulting in low system security.In order to avoid this problem,an adaptive control system for resisting network dangerous signals is proposed.According to the overall structure of the hardware,the data packet filter module is designed to convert the intrusion signal into sinusoidal signal,and the identification device is installed between the antenna and the receiver to ensure that the sinusoidal signal received by each array element has amplitude gain.After the amplitude reduction of the frequency conversion circuit,the short circuit can be avoided.The S3C2440a processing chip is used to control the frequency converted signal in a closed loop,and the dangerous signal is located according to the adaptive theorem.The"0"or"1"dangerous signal control word can be used to gain the resistance benefit,thus completing the design of the adaptive control system.The experimental results show that the maximum control efficiency of the system can reach 95%,which ensures the system has the ability of safe signal transmission.
