Abstract

The invention discloses a positioning method and system of a building inner air pipe leakage point, relating to the building engineering detection technical field, and can accurately position a building inner air pipe leakage point. The positioning system comprises: a heat exchanger connected to an air pipe to be detected in a building through a connecting pipe; and a thermal infrared imager arranged on one side of the air pipe, and capable of moving along the extension direction of the air pipe, wherein the heat exchanger heats the air pipe to be detected, and then the thermal infrared imager moves along the extension direction of the air pipe to obtain the infrared thermal image of the air pipe. The positioning method comprises: heating the air pipe to be detected in a building; obtaining the infrared thermal image of the air pipe; and analyzing the obtained infrared thermal image to determine an air pipe leakage point. The positioning method and the positioning system are suitable for building air pipe leakage point positioning.

Description
