摘要
为实现庭院植物灌溉自动及远程控制，设计了可远程控制的微型家用自动灌溉系统。该系统具有自动、手动和远程控制灌溉3种工作模式。以ARM微控制器构建智能控制单元，实现每日定时自动灌溉；通过按键可实现手动灌溉；利用GSM网络，通过手机短消息发送控制指令可实现远程控制灌溉。灌溉水源为自来水或水箱，设置减压阀的开度可实现水压调节。针对植物的需水量的不同，设置各出水管的流量控制器可实现需水量的调节。通过试验，系统能实现各种灌溉模式；分别测试了灌溉水压为0．3～1．2MPa，出水管流量控制器开度分别在1／2和最大处，灌溉时长1min的灌溉水量，最小值为283mL，最大值为619mL。
The program designs an micro home auto-irrigating system which can be controlled far away. The function of the system includes auto-irrigating, manual operation and remote control. The system based on ARM single-chip, it supports daily clock timing control and manual irrigation by pressing keys and remote control by sending control command from mobile phones based on GSM. Irrigation water is from tap water or water tank, we can adjust water pressure by adjusting the reducing valve. In view of the water requirements of different plants, we control the water flow rate through the flow controller of the outlet pipe. The system is able to realize the functions--testing the water-irrigation capacity while the scope of the water gage is between 0. 3 to 1.2 MPa during 1 miniue, and the value of the water pipe controller is half and max, then the result of the measure is 283 mL to 619 mL.
