温室大棚GSM网络远程自动化控制系统的研究

A Study of the Greenhouse GSM Network Remote Automatic Control System

本系统是一个以AVR单片机为主控制器,通过传感器获取空气湿度、空气温度、土壤温度、光照强度等环境参数,利用GSM网络与移动设备进行数据通讯,实现对大棚空气温湿度、土壤温湿度、通风、灌溉、施肥的远程监控与远程控制。只需一次性设置好参数需求,系统便可长时间自动管理,也可通过手机人为干预。通过实际测试表明,该系统稳定可靠,数据准确,响应快速,并且实现了自动控制和手动控制的结合,具有很强的实际应用推广价值。

Using an AVR SCM as the MCU, this system enables remote supervision on and control of temperature and humidity of the air, temperature and humidity of the soil, ventilation, irrigation and ferti- lization in the greenhouse by obtaining humidity and temperature of the air, temperature of the soil, illumi- nation and other environmental parameters through sensors and communicating with mobile devices through the GSM network. All we need to do is set the required parameters and the system will automatically man- age all for a prolonged period of time. Of course, human interference through mobile phone remains possi- ble. Pilot operation shows that the system is stable and reliable, the date accurate, its response fast, and combination between automatic control and manual control enabled. It is, therefore, of high value to popu- larize this system.
