The Design Of Remote Control System For Water Supplying Pipelines Based On GPRS

The Xiamen water service group at present has Gao Dian, Xing Lin, Ji Mei, Meishan, Lin Ban, Shang Li six water works,awaits two construction is Xiang An and Hai Cang works. The Xiamen daily water supply ability amounts to 1.2 million tons, the pipe network of supplies water nearly more than 1,500 kilometers, the city water used popular rate reaches 98.92%. Along with the urban construction expansion, the Xiamen peripheral countryside zone also gradually uses the tap water, The water supply pipe network unceasingly expands. In the so great scope, must guarantee the user to be able the normal water used, also must guarantee the water supply pipe network pressure as for too high does not cause the water supply pipe network broken tube, therefore the pipe network pressure monitor appears especially importantly.Because the test point of water supply pipe network is so many, moreover distributes broadly, simultaneously requires the water service pipe network data security high, transmission to be short. The conditions based on this labor the requirement, the wireless monitor obtains the broad application in the water service pipe network pressure monitor. The original wireless communication model uses the Digital transmission, it need more foundations run maintenance cost, also is ill the supervisory system which should the city network of water service expand causes to expand accommodates. Unceasingly expands in the GSM network cover scope, has maturely become maturely, stable, in the reliable communication network foundation, in view of the GPRS new service, causes the supervisory system use GPRS to come possibly in the water supply pipe network.This system uses the GPRS communication model to construct the water supply pipe network monitor system. The lower position computer(remote terminal unit RTU) by the monolithic data mining circuit module, the solar energy power supply module and the GPRS connection module is composed; The monitoring computer is composed by the server and controlling computer, two composes the backup model. Carries on gathering as well as the display to the pressure data, auxiliary city water supply dispatch work. In this article,The first chapter completes to the water supply SCADA system as well as the GPRS brief introduction; the Second chapter introduction water supply pipe network pressure monitoring network mode, as well as with original communication mode contrast; the Third chapter completes the design of remote monitoring system, including software as well as hardware design;the Fourth chapter completes the hardware circuit design of RTU; the Fifth chapter completes monitoring computer design; the Sixth chapter completes the system software design.Demand can the better adaption water supply pipe network monitor area unceasingly expand which through this system, the valid coordinate city water supply dispatch work, causes the water supply pipe network pressure in the permission scope, simultaneously enables the Xiamen resident to drink relieved water.
