摘要
针对传统温室控制在远程控制中存在的局限性,构建了一种基于以太网的新型检测平台-LXI(LANExtension for Instrumentation,局域网的仪器扩展),它能远程获取温室的环境信息。该系统由上位管理机、网络芯片STE100和智能节点组成,采用LXI网络拓扑结构的总线方式,以ARM966ES微处理器STR912为控制器。该系统软件主要是实现uCLinux内核的移植和Web远端信息的访问,客户端用户只需要通过Internet远程连接即可访问温室的环境信息。
In view of the limitation of traditional greenhouses remote control, a new detecting platform based on ethernet technology - LXI network is proposed. It can collect environmental information of greenhouse by remote control. The system design mainly includes field controller based on the ARM966ES microprocessor and the uCLinux operating system. In hardware design, the system consists of host computer, ARM966ES microprocessor STR912 and intelligent nodes with LXI networked. The software design of system includes transplant of uClinux in the STR912 microprocessor, the realization of TCP/IP agreement and web technology that based on the uCLinux kernel. All of these enable remote users obtain the greenhouse environmental information through the Internet connection in B/S model.
