基于GSM网络的蔬菜大棚环境参数监测系统

Environmental parameters monitoring system for vegetables greenhouse based on GSM network

根据目前农村蔬菜大棚种植分散的特点,设计了一种基于GSM的大棚环境参数远程监测系统。该系统有采集监测终端、GSM网络和手机监控终端组成。采集监控终端采用温湿度传感器SHT11以定时方式和随机方式实现蔬菜大棚中温湿度的检测,通过TC35I模块以短消息的方式与手机监控终端完成数据的交换。试验测试结果表明：该系统的温度监测范围为-10~40℃,误差为±0.4℃,湿度误差为±3%,满足温湿度测量精度的要求。

According to the dispersed nature of vegetables greenhouse cultivation in current rural areas,a remote monitoring system for greenhouse environmental parameters based on GSM was designed.It was composed of the acquisition monitoring terminal,GSM network and the mobile monitoring terminals.The acquisition monitoring terminal used SHT11 in regular and random way to realize the detection of temperature and humidity in the greenhouses,and used TC35I module through the short message to complete the data exchange with mobile data terminals.The experimental testing results show that： the system monitors the temperature range of-10~40℃ at ±0.4℃ error and the error humidity of ±3%,and meets the accuracy requirements of temperature and humidity.
