为满足设施农业对精准控制与实时视频的要求,提出将基于ZigBee与3G技术的无线远程传感网络应用于设施农业中,构建一种高效的设施农业远程精准测控系统。该系统通过ZigBee无线传感网络实现本地环境信息的无线采集并上传到嵌入式服务器端。通过3G网络与Internet无缝连接,实现大范围的无线接入,采用B/S模式,实现远程实时监控环境信息与视频信息。通过内嵌的专家系统模型,实现自动化、智能化控制。试验结果表明,该系统性能稳定,信息无线采集与传输、环境自动调控及远程可视化调控均达到实际需求,同时具有很高的实时性及可扩展性。
Aimed at meeting the requirements of facility agriculture precision control, a kind of high efficient remote precise measurement and control system of facility agricultural based on ZigBee and 3G is proposed. Through the ZigBee wireless sensor network, the system realize the collection of local environmental information and upload the data to the embedded server. The system connect internet through 3G network, which could construct a big range and low cost wireless network. B/S (Browser/ Server) structure was used in the system, which could realize remote real-time monitoring environmental data information and video information. The embedded expert system model make this system automatic and intelligent. The experimental results showed that the performance of the system was quite stable and the system satisfied the design requirements in real-time data acquisition wirelessly, environmental automatic control and environmental visualization control remotely. And this system has a very well real- time nature and expansibility. The system has a good application prospect in automatic and intelligent facility agriculture.
