摘　　要：为了解决无线传感网与互联网异构通信以及实现无线节点的有效管理问题,考虑SNMP协议的简单、通用、安全等特性,设计一种基于SNMP的无线传感网网关。该网关实现无线传感网与互联网的数据通信,并基于SNMP协议实现对无线节点的管理。硬件部分,该网关以STM32F103VCT6为核心微处理器,使用SPI接口配合ENJ28C60以太网控制器实现以太网通信接口,使用USART串口配合无线传感芯片cc2530实现无线传感网通信接口;软件部分设计基于Lw IP协议栈的私有SNMP代理。测试结果表明,该网关运行稳定可靠,具有一定的实用价值。In order to solve the problem of heterogeneous communication between wireless sensor networks and the Internet and the problem of effective management of wireless nodes,considering the features of SNMP protocol such as simple,universal and secure,etc.,we designed an SNMP-based wireless sensor network gateway. The gateway realises the data communication between wireless sensor networks and the Internet,and achieves the management of wireless nodes based on SNMP. In hardware part,the gateway uses STM32F103VCT6 as core microprocessor,uses SPI interface in conjunction with ENJ28C60 Ethernet controller to implement Ethernet communication interface,and uses USART serial port in concert with wireless sensor chip cc2530 to implement wireless sensor network communication interface. In software part,we design an Lw IP stack-based private SNMP agent. Test results showed that the gateway ran stably and reliably,and had certain practical value.
