针对传统温室有线数据采集系统存在着成本较高、可靠性和移动性较差等问题,提出了一种由微机与GP32单片机系统为核心的温室无线数据采集系统,通过CC2420无线收发模块实现温室内各种生长环境检测传感器无线化,现场从机采集的数据通过无线信道传送到主机,主机通过RS232与上位机PC进行串行通信,采用Visual Basic 6.0作为软件开发工具设计了实时监控平台,从而实现温室内作物生长环境的无线智能调控。针对现代温室的生产特点设计,它可以对温室内的多种环境参数进行有效的监测与控制,从而提高了温室生产的技术水平,减轻了劳动强度,提高了劳动效率。

To solve the problems of the traditional data acquisition system in greenhouse, such as high cost, low reliability and mobility, a wireless data acquisition system under greenhouse environment based on microcomputer and GP32 monolithic processors is proposed. The uses of CC2420 wireless transceivers make various testing sensors wireless under greenhouse environment, and the data collected by slaves is transmitted to the master through radio communication; then the data is serial communicated from the master to PC using RS232. Visual Basic 6.0 is used as software develop tool to design the real-time monitoring platform, which can intelligently adjust and control the growth environment of crops in greenhouse. The system designed could monitor and control various parameters effectively because it is designed according to the production features of the modem greenhouse. Thus the technological level of greenhouse production is enhanced, the labor intensity is decreased and the labor efficiency is improved.
