设施环境无线监控系统的设计与实现

针对设施农业生产环境监控过程中信息监测点和设备控制点分散的情况,设计了一种具有自组织跳转数据传输功能的通用性无线监控系统.以具有ZigBee无线数据传输功能的JN5121模块为核心,设计传感器输入接口和设备控制输出接口,研制实现现场信息的获取和设备控制的前端无线节点;以ARM9为核心扩展多种资源接口作为监控系统主机硬件,在Linux操作系统平台下使用MiniGUI编制监控功能和人机交互界面,通过对前端无线节点的统一协调指挥,完成对环境信息的采集分析和对设备的综合控制.结果表明,系统具有成本低、通用性强、可扩展性强、可靠性高等特点,可方便地应用于温室、大田、养殖等到各种场合的环境监控,从而满足用户的不同需要.

Design and implementation of wireless monitoring and control system for protected environment

As the information monitoring and equipment control points for facility agriculture production environmental monitoring were scattered, a universal wireless monitoring system was designed with functions of self-organization jump and data transmission. With JN5121 module that has ZigBee wireless data transmission function as the core, sensor input and equipment control output interfaces were designed and front-end wireless nodes for local information acquisition and equipment control were developed. Host hardware with multi-resource interfaces based on ARM9 core was designed and monitoring function and man-machine interface were implemented using MiniGUI on Linux platform. Environmental information collection and analysis and integrated control of the equipment were accomplished through the unified coordination and command to the front-end wireless nodes. Results show that the system has characteristics of low cost, high universality, good expansibility and high reliability; and can be easily applied to environmental monitoring and control under different conditions such as greenhouse, field and animal house, to meet different needs of users.
