基于ENC28J60的新型自动气象站网络通信系统

为了有效提高DZZ1-2型新型自动气象站的现场维护调试及故障诊断效率,广东省气象局基于ENC28J60自主设计了一款嵌入式网络通信系统.通过设计SPI接口电路和裁剪TCP/IP协议栈,构建微控制器初始化配置、以太网驱动以及网络数据传输等功能模块,从而实现系统与上位机软件命令数据交互、数据帧高速传输的设计目标.实际应用效果表明,该网络通信系统运行稳定,能响应维护操作指令快速获取设备运行状态,较好地满足气象设备运行保障的快速、高效、可维护性强等业务需求.

Network communication system of the new automatic weather station based on ENC28J60

In order to effectively improve DZZ1-2 type of new automatic weather station's field maintenance and fault diagnosis, Guangdong Provincial Meteorological Bureau has used ENC28J60 to design an embedded network communication system.By designing SPI interface circuits and clipping TCP/IP protocol stack,such as initialization configuration, Ethernet driver and network data transmission, so as to achieve the design goals,including command and data interaction of the system and the host computer, high-speed transmission of the data frame.Practical application results show that the network communication system can operate stably, response to maintenance instructions to obtain the running state of the equipment quickly, and meets the requirements of operation support of meteorological devices with quickness, high efficiency, strong maintainability.
