Heat supply pipe network leakage positioning system and heat supply pipe network leakage positioning method

Abstract

The invention belongs to the field of monitoring heat supply pipe network faults, and particularly relates to a heat supply pipe network leakage positioning system and a heat supply pipe network leakage positioning method. The system comprises a control center and a heat exchange station terminal, wherein the control center is composed of a computer, a multi-channel driving receiver and a piece of data transmission equipment; the heat exchange station terminal is composed of a piece of heat exchange station terminal data transmission equipment, a heat exchange station terminal microprocessor, a heat exchange station pressure sensor and a heat exchange station flow sensor; calculation programs of a heat supply pipe network are arranged inside a memory of the computer, so that data fed back by the heat exchange station terminal are stored and processed; once the heat supply pipe network has leakage, the pipe section at which the leakage point is located can be identified by obtaining the hydraulic power working condition of the system having the leakage by calculating the data of the change on the pressure and the flow at the entrance of a heat exchange station through the programs, wherein the data are fed back by monitoring points at the tail end of the heat exchange station; and furthermore the specific position of the leakage can be confirmed through the auxiliary monitoring of an infrared thermometer.

Description

technical field

[0001] The invention belongs to the field of fault monitoring of a heating pipe network, in particular to a leak location system and a location method of a heating pipe network. Background technique

[0002] With the development of my country's social economy, the northern cities are rapidly changing from the previous district heating to centralized heating, the number of heat users is increasing, the coverage of urban heating pipe networks is increasing, and corresponding accidents occur The rate and resulting economic loss will also increase. Therefore, we have higher and higher requirements for the safety of the heating pipeline network itself, and the demand for the accident leakage detection system of the heating pipeline network is also more urgent. At present, most of the domestic large-scale heating pipe networks use the method of outdoor direct burial laying, and most of the monitoring adopts the SCADA system to realize various functions such as data...
