基于移动通信网络的温室环境测控系统研究

Research on the System of Greenhouse Environmental Temperature Measure and Control Based on Mobile Communication Network

基于移动通讯网络实现了大型温室中温度、湿度、光照及二氧化碳浓度等环境参数的远程测量与控制。整个系统由中心站系统和测控基站系统组成,中心站系统包括服务器及应用软件、GSM模块和数据库系统;测控基站系统包括单片机系统、传感器、控制执行机构和GSM模块。由于系统硬件采用了模块化设计方法,软件开发用嵌入式操作系统完成,使系统易于扩展、维护和移植。采用GSM技术实现远程测控,解决了大型温室群采用有线传输网络一次性投资过大,使用维护不便等问题。由于GSM网络覆盖全国,研究成果可实现跨地域数据实时分析与处理。

A remote survey and control system for greenhouse based on GSM-SMS （Short Message System） was developed in this paper. The system comprises a centre station and some base stations, and which realized the parameter information collection and auto regulation, such as air temperature, air humidity, intensity of illumination, CO2 density in the greenhouse. The centre stations consist of a server, a GSM module and a database system, and the base station consist of a GSM module, a single chip microprocessor, some sensors and actuators. Modularization design procedures were taken in hardware and embedded operating system in software development, which make the system easy to be extend, maintain and update. The work can also be used in real-time data analysis and process in wide areas.
