摘　　要：为解决温室监测"低端化"的问题,充分利用现有的以太网资源进行上位机与测控现场串口设备之间进行数据传输,该文设计了基于SoC芯片C8051F020与网络芯片RTL8019AS的以太网转换接口,实现了基于UDP/IP协议的以太网通信。用单片机C51语言编程实现了网卡脱离PC机环境制约下达到正常通信的功能。指出该系统具有实时性、智能化并能摆脱监控系统现场对计算机环境要求的限制等优点,具有良好的推广应用前景。In order to solve the problem that the circumstance parameters are monitored easily in the greenhouse, in this paper, an Ethernet conversion interface based on C8051F020 and net chip RTL8019AS is designed, which makes full use of Ethernet resource for data transfer between PC and serial port device in the monitoring field. It realizes Ethernet communication based on UDP/IP protocol. Then the C51 programming language of single chip implement the normal communication when the card deviates the environment limitation of PC. The system has many advantages such as real - time, high reliability, intellectualized, and it can also extricate the monitoring system from environmental limit in on - site uses, it has good application prospects.
