基于GPRS的三峡库区水位监控系统设计

Design of the Freshwater Line Monitoring System for the Three Gorges Reservoir Area Based on GPRS

长江三峡工程是一个利国利民的大工程,影响和制约着当地国民经济的可持续发展。本文针对长江三峡库区水位测量与控制,提出了一种基于GPRS的水位监控系统。本系统分为监控中心和测量终端。测量终端采用液位传感器,将液位传感器接上线缆后沉入水底,将测出来的水压信号转变成电信号通过电缆传输到测量终端CPU,CPU将此数据转换为水位高度后通过GPRS网络以数据报的形式传输到监控中心实时显示出来。如果水位高度超出阈值,监控中心将发出报警信息通知监控人员以便及时作出处理。

The Three Gorges project of the Yangtze River is a good project, influencing and restricting the sustainable development of local economy. A kind of a water-level monitoring system based on GPRS is designed with the measurement and control of the water level of the Three Gorges Reservoir Area. This system consists of the monitoring center and measuring terminal. The measurement terminal is the liquid level sensor . The liquid level sensor is connected to cable sink to the bottom. The measured pressure signals into electric signals to measure the terminal CPU via cable transmission. CPU through GPRS real-time network in the form of datagram transmission to the monitoring center display this data is converted to the water level height. If the water level exceeds the threshold, the monitoring center will send alarm information notification monitoring personnel in order to make timely treatment.
