THE RESEARCH OF AUTOMATIC WATER-SAVING IRRIGATION SYSTEM IN THE MIDDLE ISOLATED GRASSLAND OF EXPREEWAY

摘要

Nowadays, the irrigation of isolated grassland not only wastes the water seriously but also has some potential hazard. Based on GSM, a composing irrigation construction in the middle isolated grassland of expressway was developed in this paper. The system provides irrigation parameters through sensors, such as flowmeter, manometer. All signals can be analyzed and delivered to the mainframe through GSM. The automatic alarm system sent alarm information through GSM to administrators, and shut off the pump and electromagnetic valve automatically when the data was abnormal.
