Problems solved by technology

However, due to the influence of various factors such as immature theory and the complexity of the actual pipe network, it is difficult to determine the location of the accident burst point in the water supply pipe network when a sudden pipe burst accident occurs, and there is a lack of effective accident burst information. Pipe positioning methods and positioning systems, few examples of successful use in actual pipe networks

Abstract

The invention belongs to the measurement field of a water supply system. Aiming to fix the position of pipe burst accident point in a water supply network accurately and rapidly, improve the accuracy of positioning, and effectively manage the related data of the operation condition of the water supply pipeline network, the invention adopts the following technical scheme: the pipe burst accident on-line positioning system for an urban water supply pipeline network is composed of a supervisory control and data acquisition system (namely an SCADA system), a data center and a master control computer; the supervisory control and data acquisition system comprises the following parts: 1. a plurality of telemetering remote transmission terminals; and 2. a communication system; the data center comprises a server which is used for monitoring process values and communicating with process hardware; and the server is provided with a database for storing on-line data of the water supply pipeline network, which are monitored according to time sequence. The on-line positioning system provided by the invention is mainly used for determining the position of a pipe burst accident point in the water supply pipeline network.

Description

technical field [0001] The invention belongs to the measurement category of water supply systems, and in particular relates to the location of pipe burst accidents in urban water supply pipe networks. Specifically, it involves an online location system for pipe bursts in urban water supply network accidents. Background technique [0002] In recent years, many cities in my country have established a data acquisition and monitoring system (Supervisory Control And Data Acquisition, namely SCADA system) of the water supply network, which monitors the water pressure, flow, water quality data and the operation of water pumps of several nodes in the water supply network. Automatically monitor, and transmit the data of monitoring points back to the control center in real time by wired or wireless means, so as to realize the monitoring of the operation of the entire water supply network. However, due to the influence of various factors such as immature theory and the complexity of th...
