摘　　要：针对高频地波雷达发射机远程监控的需要,给出了一种以数字信号处理芯片ADSP-BF532作为处理器,结合高速模数转换器AD9244和非PCI以太网控制器LAN91C111的高速数据采集、处理及以太网传输系统的软硬件设计方案;该系统可对高频地波雷达的发射波形信号进行高速采集、处理,并通过以太网连接至上位机,从而实现对发射机的自动故障监测和远程控制;其中的以太网接入部分,对于其他需要接入以太网的嵌入式系统设计具有参考意义。According to requirements of remote monitoring of high frequency ground wave radar transmitter, a monitoring and controlling system of radar transmitter is designed, which is based on digital signal processor （ADSP-BF532）, high-speed ADC （AD9244） and non-PCI single chip Ethernet controller （LAN91C111）. The functions of this system include high-speed data sampling and processing, connecting to Ethernet via LAN91Clll, and then realize the function of detecting the transmitting waveform, fault diagnosis and remote controlling. The design of software and hardware are both described. Hereinto, the design of Ethernet connectivity part has the reference significance for other embedded applications that need connecting to Ethernet.
