Heat-supply network failure quick detection system

Abstract

The heat-supplying pipe network fault quick detecting system is characterized by that it is composed of a control centre formed from computer, multichannel drive receive, modem and data-set which areconnected sequentially and a remote transmission terminal formed from terminal data-set, terminal dmodem, terminal multichannel drive receiver, microprocessor and terminal A / D converter which are sequentially connected, in which the terminal A / D converter is respectively connected with heat supplying pressure sensor and heat-supplying flow rate sensor. Said computer memory contains software program system of pipe-bursting and leakage fault of heat-supplying pipe network. Said ivnention utilizes the correspondent relationship of heat-supplying pressure change between monitoring point and non-monitoring point to detect fault.

Description

technical field

[0001] The invention belongs to the measurement category of heating pipe network faults, and in particular relates to the detection of urban heating pipe network faults. Background technique

[0002] In northern my country, due to the cold climate in winter, most of the indoors are heated by central heating of the heating pipe network. The heating pipe network is mostly buried in the ground, and the pipes often have failures such as heating bursts and leaks due to corrosion and other reasons. The light ones will lead to waste of heat energy, and the severe ones will cause major accidents, which will definitely affect residents’ heating in winter and their lives. property and safety. Therefore, it is urgent to establish a detection and monitoring system for heating pipe network failures. Although, some urban heating pipeline systems have set up a heating pipeline network data acquisition system to automatically monitor the h...
