一种串口与UDP协议实现透明转换的方法

摘要

针对物联网技术Internet的接入要求，应用AVR单片机和以太网控制芯片设计开发了串口（RS-232）与UDP协议数据格式双向透明转换通用网关，为智能仪表或传感器的以太网接入和IP网络的统一管理提供了途径。通过测试验证了本方法的有效性、实时性和可靠性。%Demand on access the internet of Things, designed a serial and UDP protocol conversion interface which base on the AVR mcu and chip of ethernet control, the smart meter or sensor can connected and managed by IP network with this interface. Test result shown this interface has effective, real-time and reliable performance.
