摘　　要：提出了基于嵌入式以太网与RS-422多机通信网为基础的设计,实现了以太网到RS-422多机通信网的数据转换,完成了对远程多个频率合成器的电源开关、输出信号频率、功率的实时控制,实现了对远程多个频率合成器的工作电压、电流、温度、信号输出功率、锁定状态等的实时监测。A communication network based on an embedded Ethernet and RS-422 multi-machine communication network is presented in this paper. The data conversion between Ethernet and RS-422 multi-machine communication network is realized. The real-time controlling is realized on the output frequency and power of a remote multiple Frequency Synthesizer（FS）. Moreover, the voltage, current, temperature, output power, and lock status are monitored in real-time as well.
