温室智能灌溉水肥一体化监控系统(英文)

Integrated Monitor System of Water and Fertilizer of Greenhouse Intelligent Irrigatio

水肥一体化是将灌溉与施肥相结合的一项综合技术,具有省肥、省水、省工、环保、高产、高效的突出优点,目前生产型日光温室的水肥一体化灌溉施肥和灌溉作业,多数依靠人工经验完成,灌溉的及时性、科学性及智控化程度不高。该研究应用STM32嵌入式系统,实时采集埋入土壤中的上、中、下3个深度的湿度传感器的数据,根据不同作物预定的施肥、灌溉策略,自动控制完成温室水肥一体化灌溉作业。该系统同时具有远程监控功能,采用全球移动通信(global system for mobile,GSM)模块给用户提供远距离短消息服务,用户不仅可以通过短信对温室灌溉、光照、通风的远程智能监测,同时可远程控制系统作业的启停,以此实现温室环境的自动化管理,达到远程施肥与节水灌溉的目的。

The integration of water and fertilizer is a comprehensive technology combined irrigation and fertilizer, which has outstanding advantages of saving fertilizer, saving water, saving labor, protecting environment, high yield and high efficiency. Currently, most of the water and fertilizer integrated irrigation and fertilization and irrigation operation in the production-based greenhouse is achieved relying on artificial experience, which is hard to achieve timely, scientific and intelligent irrigation. In this study, the application of STM32 embedded system realized the real-time collection of the data from the humidity sensors buried in top, middle and low depth of soil, and water and fertilizer integrated irrigation work was completed in the greenhouse through automatic control according to the predetermined fertilization and irrigation strategies for different crops. Moreover, the system had remote monitoring function, which used the global system for mobile （GSM） module to provide users with remote short message services, and therefore, the users could not only achieve the remote intelligent monitoring on the irrigation, light, ventilation of the greenhouse through short messages, but also could start and stop the remote control system operation, so as to realize the automatic management of the greenhouse environment, achieving the purpose of remote fertilization and water-saving irrigation.
