摘要
针对泛在测控网络环境中构建远程分布式ZigBee无线测控系统的需要,设计一个嵌入式无线传感器网络网关;采用无线收发芯片CC2420和以太网控制芯片ENC28J60,配合微控制器MSP430搭建网关硬件平台;网关软件系统则以ZigBee协议栈Z-Stack的操作系统抽象层OSAL为核心进行扩展,整合嵌入式TCP/IP和oSIP协议栈以满足嵌入式系统硬件资源条件限制及任务实时性要求;应用测试结果表明,该网关能够实现水质监测站机房分布式ZigBee环境监测节点与Internet远程工作站的异构网络数据交换,且性能稳定可靠。
An embedded wireless sensor network （WSN） gateway used to construct remote distributed wireless measurement and control system in heterogeneous network environments is proposed, and its hardware platform is composed of wireless transceiver chip CC2430, Ethernet controller chip ENC28J60 and microcontroller MSP430. The operating system abstraction layer （OSAL） of ZigBee protocol stack Z- Stack, as the core of gateway software system, is extended, and embedded TCP/IP stack and oSIP stack is integrated together to meet the embedded gateway system hardware resources constraints and real--time requirements of tasks. The application test results show that the gateway can realize heterogeneous network data exchange between distributed ZigBee environmental monitoring nodes of water quality monitoring stations and Internet remote workstations, and its performance is stable and reliable.
