摘　　要：传统的无线电监测系统主要通过单站监测的方法对信号突变进行监测,但不能对复杂的高频宽带无线电信号突变进行准确监测。因此,设计无线传感网络信号突变监控模块的实现电路,其由高频激发器、窄带滤波器、程控放大器、A/D采集电路、FPGA和主控制器等构成。编制开发无线传感网络信号突变监控模块的上位机控制软件,并向下位机主控器传递控制指令,确保各电路模块协作完成无线信号突变的监控。实验结果表明,所设计监控模块的电路,可对无线传感网络信号突变情况进行准确、高效率的监控。The traditional radio monitoring system monitors the signal mutation with the method of single station monitor- ing, but can＇t monitor the complicated signal mutation of high-frequency wideband radio accurately. Therefore, the realization circuit of the signal mutation monitoring module for wireless sensor network was designed, which is composed of the high-fre- quency exciter, narrow-band filter, programmable amplifier, A/D acquisition circuit, FPGA, main controller, etc. The host com- puter control software of the signal mutation monitoring module for wireless sensor network was developed to transmit the control instructions to the slave computer, so as to ensure the monitoring of wireless signal mutation by collaboration of circuit modules. The experimental results show that the designed monitoring module circuit can monitor the wireless sensor network signal muta- tion accurately and efficiently.
