Embodiment Construction
[0057] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0058] Such as figure 1 As shown, it is an overall flowchart of the seismic source type and seismic source distance measurement and positioning in the present invention.
[0059] There are 12 steps in total. Steps 1 to 5 are to filter background noise and identify processes that trigger vibrations. Steps 6 to 12 are the analysis process for the source type and source orientation respectively.
[0060] Step 1: Install a three-axis numerical vibration sensor at four corners every 10 meters in the tunnel. The network protocol frame header of each sensor stores the factory serial number of the sensor, and each serial number corresponds to the installation position of the sensor. If the sensor installation position density is too small, it will lead to inaccurate judgment of the source direction. Allocate two memory buffers for each triaxial vibration s...
