基于gprs的供水自动化监控系统学士学位论文.docVIP

摘 要 随着工业技术的飞速发展和城市规模的不断扩大，城镇、农村、厂矿、油田等地的自来水用量正在急剧增长，供水系统节点分布也越来越广泛。建立一个有效的监测系统，对供水系统进行实时的数据测量与分析，以达到合理调度水资源分配、发现故障、消除隐患、节约水资源的目的，是非常必要的。将分布采集的自来水管网数据，利用通用分组无线业务GPRS(General Packet Radio Service)进行即时传输，达到对供水系统进行实时监控的目的。 GPRS (General Packet Radio Service，通用分组无线业务)作为从2G向3G过渡的2.5G的技术，正在工业自动化领域得到越来越广泛的应用。本文提出一种基于GPRS的供水远程自动化监控系统，该系统以GPRS网络作为远程信号的传输平台，并结合Visual Basic语言程序与无线终端DTU及数据采集模块RTU解决了监控中的无线通信问题，具有更好的可靠性和实时性。本文首先介绍了GPRS技术的基本原理，然后详细描述了系统的相关技术及硬件的参数和配置，采用动态域名解析解决了无固定IP的问题，并在此基础上详细介绍了监控中心软件的实现过程及各部分实现后的效果。最后阐述了本设计系统的优点与不足，提出下一步改进方向。 关键词：远程监控 监控中心 TCP/IP协议 GPRS Abstract Along with the fast progressing of industrial technology and the urban area, the usage amount of tap water is increasing rapidly, so as distributing scope of nodes in the pipeline networks of water supply. Its necessary to establish an effective real-time measure system for measuring and analyzing data of pipeline network of water supply, for the aim of scheduling the water resource properly, finding malfunction, avoiding hidden trouble and saving the tap water. By using the GPRS to transmit data gathered from pipeline network of water supply can get the aim for real-time measuring. GPRS (General Packet Radio Service), as the 2.5 generation technology transition from 2 generation to 3 generation, is widely applied in industrial automation field. This paper presents a GPRS-based remote network monitoring system. The system uses GPRS network as the transmission platform of long distance signal, Combined with Visual Basic programming language with the wireless terminal DTU and data acquisition module RTU solved the wireless communication problem; the real time and reliability is better. This paper firstly introduces the basic principle of GPRS technologies, describes the detailed system relevant technology and the parameters of hardware and configuration, using dynamic DNS solve the problem without a fixed IP, and on this basis introduces in detail the monitoring center software realization and the
