基于CAN总线和Linux的微灌监控系统

为了节约农田灌溉用水，提高水资源利用效率，实现自动微灌控制，根据精细农业的实际需求，本文提出了基于CAN总线和Linux的微灌监控系统，该系统由数据信息采集模块、嵌入式中央处理模块、灌溉控制模块、CAN总线网络四部分组成，可按设定的时间间隔自动采集空气温湿度、光照辐射强度等信息，并结合作物生长信息，经理论计算，决策所需灌溉水量，利用电磁阀来自动调节控制水量补给，实现作物微灌的自动化，优化植物的生长环境，提高水利用率。系统运行稳定，效果良好，能够实现准确的信息采集和可靠的分布式控制。

Micro-irrigation monitoring system based on CAN bus and Linux

According to the actual requirements of precision agriculture, a micro-irrigation monitoring system based on CAN bus and Linux was designed to save the farm irrigation water, improve the utilization rate of water resource and achieve the automatic control of micro-irrigation. It was comprised of a data collection system module, an embedded central processing module, an irrigation control module and an CAN bus network. To realize the automation of micro-irrigation, optimize the plant growth environment and improve water utilization rate. the system can collect the temperature, humidity and illumination intensity of farmland automatically at a specified time. and determine irrigation requirement by theoretical calculation according to the crop growth status, and then control the water supply using electromagnetic valves. Application in demonstration areas proved that, the system is stable and effective, and can collect information accurately and distributed control stably.
