GIS (Geographic Information System)-based heat supply network leak detection system and method thereof

Abstract

The invention discloses a GIS (Geographic Information System)-based heat supply network leak detection system and a method thereof. The GIS-based heat supply network leak detection system comprises a data collection and monitoring subsystem, a real-time service subsystem, a database and a GIS platform management subsystem. The data collection and monitoring subsystem is used for collecting and transmitting leak monitoring data of fixed monitoring points of a heat supply network. The real-time service subsystem is used for communicating with the data collection and monitoring subsystem to obtain the leak monitoring data and store the leak monitoring data in the database, and analyzing the leak monitoring data. The database is used for storing the leak monitoring data, digital map data and heat supply network pipeline data. The GIS platform management subsystem is used for communicating with the database and displaying the leak monitoring data and the influence area of an accident of an accident monitoring point on a heat supply network digital map according to second leak alarming information. Compared with the prior art, the GIS-based heat supply network leak detection system can timely and accurately find the heat supply network leak accidents, a GIS platform can accurately position the leak accidents and display the accidents on the map, and the leak accident information can be timely supplied to corresponding staff members.

Description

technical field [0001] The invention relates to the technical field of leak detection of heating pipe networks, in particular to a GIS (Geographic Information System or Geo-Information system, geographic information system)-based leak detection system and method for heating pipe networks. Background technique [0002] With the continuous development of the city, there are more and more problems in the city. Among them, the research on the leakage detection of the heating pipe network is a new topic that the current heating enterprises and researchers are facing together. The modern large-scale heating system is a complex technical system with a huge number of components and complex working conditions. The heating pipe network is the weakest link in the heating system. With the expansion of the scale of the central heating system and the age of operation With the growth of heating pipe network failures in various places, leakage failures are the most common. As an important ...

Problems solved by technology

In view of this situation, it is often difficult to accurately detect leaks with small leaks by using this method.

In addition, like other listening methods, the correlation analysis method also needs to obtain accurate results under the condition of less environmental noise interference. period of time, making it less available

[0010] It can be seen that the existing technologies listed above are all applicable to the situation where there are serious leakage accidents in the heating pipe network, and it is difficult to achieve the purpose of accurate detection for small-scale leakage accidents. In addition, it is difficult to use the above-mentioned existing technologies Determine the exact location of the spill
