摘　　要：工业领域中控制设备使用的串口通信抗干扰性不强,而以太网通信具有更好的抗干扰性,并且控制设备和以太网具有联网的趋势。提出了一种以高性能微处理器(C8051F120)和以太网控制芯片(CP2200)为核心的转换系统,把从串口(RS232或RS485)中接收到的数据,通过以太网进行传输,提高了传输数据的抗干扰性,节省了更新换代成本,达到了远程监控、远程通信的目的。Serial port communication used in control equipments of industry domain has poor anti-interference. Ethernet communication has better anti-interference, and it is the current trend that control equipments connects with Ethernet. A convertion system is proposed by using high performance microprocessor （ C8051 F120） with Ethernet control chip （CP2200） as processing center. This convertion system transfers data from serial port using Ethernet, and improves anti-interference of data communication. The cost of regeneration is saved in this system, and remote monitor and control, remote communication are implemented.
