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...

Abstract

The invention discloses a method for recognizing the type of a vibration source of a tunnel, and a vibration source positioning method. The method for recognizing the type of the vibration source comprises the following steps: setting distance setting monitoring regions in the tunnel at intervals, wherein four corners of each monitoring region are respectively provided with a triaxial vibration sensor; collecting X-axis, Y-axis and Z-axis acceleration analog quantities of the triaxial vibration sensor in real time through the triaxial vibration sensor, and converting the acceleration analog quantities into digital quantities; carrying out the calculation and analysis of the monitoring data of the triaxial vibration sensor: building a vibration triggering algorithm; filtering background noises, judging the focus direction through longitudinal and lateral stationing combined analysis, and measuring the distance of a focus through a difference point of transverse and longitudinal wave propagation; and finally achieving an effect of precisely determining the focus. The method provides strong technological guarantee for the early warning and quick response of power safety production.

Description

technical field [0001] The invention relates to a vibration source type identification and positioning technology for preventing large-scale construction machinery from damaging an underground tunnel, in particular to a vibration source type identification method and a vibration source position positioning method for a tunnel. Background technique [0002] With the development of the economy and the continuous maturity of technology, the development of urbanization continues to deepen, and the utilization rate of underground space is getting higher and higher. Various communication and power facilities are often distributed in municipal and power tunnels. The safe operation of tunnels is related to the safety of the city. Security construction and development. At present, the underground space monitoring industry has shown explosive development, and has grown into a new type of industry with a certain market size and high technical level. As the main component of urban unde...
