摘要
目前,灌区水情信息检测方法存在实时性差、效率低和数据共享困难等问题。为此,在分析信息传输方式、成本及其可行性的基础上,结合GPRS的技术特点,利用带GPRS Modem的信息采集终端,通过设计数据传输协议,编制灌区信息检测中心软件,构建了基于GPRS的灌区信息检测系统。测试结果表明,该检测系统数据传输可靠、稳定性高,可为灌区信息检测自动化提供理论依据与技术支持。
Currently, poor real - time, low efficiency, inefficient difficulties in data sharing can be the problems of the method of water information monitoring for irrigation area. The purpose of this paper is to describe the overall architecture of water information monitoring system for irrigation area by using GPRS technology. With analyzing the information transmission, the cost and the feasibility of implementation, the system is designed to propose a scheme for promoting the automation of information monitoring for irrigation area. The main part of this work is to design a data transmission protocol that allows the development of information monitoring system for irrigation area. The presented information monitoring system has been tested and results demonstrate the reliability and stability of software to guarantee hard real - time execution.
