基于 GPRS 的灌区水位智能监测系统设计
The Design of an Intelligent Wireless Based Water Level Monitoring System for Irrigated Land Area
摘要
Abstract
In order to monitor and gather the groundwater level data of irrigated land area in Sanjiang Plain in real time , a wireless based water level monitoring system is designed .Ultrasonic sensor is used as part of the terminal to collect and monitor the water level in real-time.GPRS networkis utilized to transport the water level data from terminals to the moni-toring center .Water level data are then processed , stored and displayed along with the automatically generated figures and curves about water-level changes.The experiment result shows that the measurement error is between 0 .1 cm and 0.5cm.The system proofs to be capable of monitoring the water level of irrigated land area in real -time while work-ing in a very stable condition .And the system is also valuable of providing scientific evidence for the local authorities to wisely and rationally develop the groundwater resources in the irrigated land area .关键词
