Design And Implementation Of Measuring System For Pipeline Networks Of Water Supply Based On GPRS

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. It's 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. Firstly, we analyze series of GPRS protocols, put forward technological difficulties during establishing GPRS data service channels, discuss the means of structuring the network based on GPRS, work out its concrete realizing scheme to structure measuring system of pipeline network of water supply based on GPRS and Internet communication networks. Secondly, we discusse how to realize the PPP link based on GPRS, put forward the scheme realizing the PPP link, realize data tranmitting with embedding TCP/IP message into PPP datagram. , implement the steady connection between GPRS terminals and the measuring center without dynamic domain name by recording IP address bidirectional, expatiates on overall realization process of the measure system of pipeline network of water supply based on GPRS from hardware and software design of GPRS terminals to programming of measuring center server. Finally we expatiate on the advantages and disadvantages of the system and put forward the plans to ameliorate the system.The realized measure system of pipeline network of water supply provides a transparent transmitting channel with the method of GPRS and Internet communication networks, and has a better property of real-time data transferring and high cost performance...
