摘　　要：介绍了一种拥有完全自主知识产权的按植物需求精准节水灌溉自动调控系统的工作原理、组成及其灌溉控制策略。系统以植物生理需水指标及土壤含水量为依据,通过无线数据传输,利用自主研发的灌溉监测控制器来控制电磁阀,实现滴灌、喷灌、微灌和低压管道等灌溉方式的自动化,同时经系统监控器通过GSM远距离无线通讯将所有灌溉事件自动输入数据库,形成各种报表,以便对灌溉数据进行统计分析。从硬件和软件两方面描述了系统的设计及实现方法。该系统使用灵活,数据传输可靠,控制节水效果好。The work-principle, composing and control strategy of a precision irrigation control system with fully self-created knowledge property right, which is in accordance with plant physiological water requirement, are introduced in this paper. Based on the plant physiological water requirement index and soil moisture, through wireless transmission, the system can use the self-developed irrigation monitor to automatic control the sprinkler, drip or low-pressure pipe irrigation system. Furthermore, the raw data can be sent to a database in main computer through GSM and appropriative tables can be created for statistical analysis. The design and realization method of this system are expounded in this paper from the aspects of hardware and software. This system has a series of advantages, such as flexible operating style, reliable data transmission, lower cost and higher efficiency of saving water.
