[0045] The following is a detailed explanation and description of the acoustic emission positioning method of the buried gas pipeline leakage point based on the Beidou positioning of the present invention with reference to the accompanying drawings.
[0046] Such as Figure 1-5 Said, the present invention discloses an acoustic emission location method for buried gas pipeline leakage points based on Beidou positioning. The present invention is based on the Beidou positioning system to obtain the location of the leakage point through time difference positioning, amplitude attenuation positioning and combined with weighted average. It solves the problem that the prior art is difficult to locate the leakage point and cannot detect the leakage of the small flow buried gas pipeline. The acoustic emission positioning method includes the following steps, such as figure 1 , 2 Shown.
[0047] Step 1. The acoustic emission sensor 3 integrated with the Beidou communication module arranged on...
