Problems solved by technology

[0007] The invention provides a method for on-site detection of heat loss in urban heating pipe network systems, which solves the problem that due to the large coverage area of ​​heating network pipes, the existing detection methods can only detect places with large pipeline leakage, and the location location is not accurate In addition, due to the complex environment around some heating pipes, the detection results will be affected by the influence of the external environment during the detection process, resulting in a large error in the detection results.

Abstract

The invention discloses an on-site detecting method for the heat dissipating loss of a heat supply pipe network system for cities and towns. According to the on-site detecting method, a heat supply pipeline, a data detecting system and a maintenance system are included, the data detecting system is used for detecting lost temperature data of the heat supply pipeline and transmitting the detected data to a database, and the database transmits the data to the maintenance system. According to the on-site detecting method, through the data detecting system, the heat dissipating loss of the heat supply pipeline can be detected in real time, and detected temperature information and position information can be displayed on a GIS platform; by arranging anti-interference detection, the influence ofthe surrounding environment on the detection result can be eliminated, the condition of wrong information is avoided, thus maintenance work of the heat supply system is accurate and orderly, and meanwhile maintenance work is more convenient and rapid; and the GIS platform is connected with a satellite map, thus when the pipeline leaks, maintenance personnel can rapidly formulate an optimum first-aid repair scheme according to the surrounding geographical condition, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of heat supply technology detection, in particular to a method for on-site detection of heat dissipation loss in urban heat supply pipe network systems. Background technique [0002] Under the situation of continuous development of economy and production, people pay more and more attention to the issue of energy saving, and energy saving and emission reduction are also regarded as a social responsibility of enterprises. Enterprise energy conservation not only responds to the national low-carbon environmental protection policy, benefits the country and the people, but also has many benefits for its own development. For chemical companies, a large amount of heat energy is transported through pipelines, and there will be non-negligible pipeline heat dissipation losses during the transmission process. Therefore, reducing the heat dissipation loss of heating network pipeline transportation can not only save fuel, but also...
