Decision on Leakage of Heat-supply Pipe Network Based on Multi-sensor Information Merge

摘要

The complicated structure of heat-supply pipe network leads to the issue that the leakage position is difficult to locate by a single sensor. We propose to exploit the merge information by multi-sensor to determine the leakage pipeline section. The mathematical model is first established according to the topology of the pipe network. Furthermore, We present the concept of leakage time difference vector group and assign the elementary probability according to the cosine of the intersection angle between the given time difference vector group and the real measured time difference vector group. Experimental results show that the proposed scheme realizes the diagnosis of the leakage pipeline section in the complicated heat-supply pipe network.
