一种多串口和以太网转换方法的研究

摘要

嵌入式系统中普遍应用RS232串口进行调试通信,但RS232串口在复杂的综合化航电处理平台中的应用却有诸多不便,而通过以太网却无相关问题.鉴于当前大多数成熟应用都需要通过RS232进行通信,设计了一种新型接口模块,实现了将多个RS232串口协议数据转换为以太网协议数据的方法.实践表明,方法能很好地应用在复杂的综合化航电处理环境中,简单方便,不影响用户调试习惯,值得推广应用.%RS232 serial port is commonly used in embedded system for debug and communication, but in complicated integrated avionics,problems appeared,while elhernet can solve these problems. As most of the existed mature applications use RS232 for communication,this paper designs a new interface module successfully in communicating between RS232 and Ethernet. The result indicates that this design can do well in applying in complicated integrated avionics without affecting user's debug habit while maintaining simpleness and convenience. In a word,this method is easy for use and worth popularized.
