基于 CAN总线和 GPRS的温室大棚监控系统的设计

摘要

Since the greenhouse has wide range and many environmental factors , we developed the greenhouse control system based on CAN bus and GPRS .The system can collect temperature , humidity, light and CO2 concentration and other environmental parameters .All data is uploaded via CAN bus and GPRS to a remote host computer .The greenhouse's temperature and humidity , ventilation equipment , supplementary light switch can be controled by the remote host computer .The remote software is developed by KingView .The experiment showed that the system works well and it can satisfy the needs of automatic monitoring of greenhouse .%针对温室大棚范围广、环境因子多的特点，提出了一种基于CAN总线和GPRS的温室大棚监控系统。在硬件方面，用单片机C8051F040采集温湿度、光照和CO2浓度等环境参数，所有数据通过CAN总线和GPRS上传到远程上位机中，同时通过上位机可以控制大棚的温湿度、通风设备、补充光源的开关。上位机软件采用组态王软件实现，具有直观和可靠性。通过试验证明，整个系统工作实时性好，操作简单方便，能很好地满足温室大棚的自动监控的需要。
