Embodiment Construction

[0039] exist figure 1 Among them, the pipe burst and leakage fault detection system of the heating pipe network is composed of a control center 1 and a number of telemetry and remote transmission terminals 6 . Wherein, the control center 1 may be located in a heat supply station or a heat supply dispatching room or the like. The remote transmission terminals 6 are respectively installed at various heating stations, pressurization stations, and several nodes of the heating pipe network to monitor the heating pressure and (or) the heating flow on-line. The control center 1 and the remote transmission terminal 6, which transmit the execution instructions by the digital transmission machine 5 and the terminal digital transmission machine 7 that transmit wireless signals, or send back the monitoring data of heating pressure and heating flow; and the control center 1 conducts The processing of monitoring data can quickly and accurately make online detection of failures such as pipe...

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...
