Problems solved by technology
[0003] Taking the coal industry as an example, because the location of the mine is buried deep underground and the stratum structure is complex, it is difficult for conventional electronic information to penetrate the bottom layer and transmit it to the ground. On the other hand, underground equipment is usually easily damaged during earthquakes. The timely discovery and rescue of survivors has brought difficulties
For example, conventional electromagnetic signals need to be transmitted about two or three hundred meters underground and can be received by the ground. The transmitting and receiving equipment will be very complicated (such as ultra-long wave equipment), and it will be easily damaged by external physical shocks.

Embodiment Construction
[0020] For coal mine vibration detection, the system such as figure 1 As shown, it includes n three-component high-precision sensors, n data acquisition units and data processing units. Each three-component high-precision sensor sends the received data on the three components to the data processing unit through the data acquisition unit connected to it. unit. If there are n outlets of the metal pipeline on the ground, use pipe clips to fix the three-component high-precision sensor on the n outlets, such as figure 2 shown. Three-component high-precision sensors such as image 3 As shown, the shock waves are collected from three directions of x, y, and z components perpendicular to each other. The frequency of shock waves generated by striking metal is between a few to tens of Hertz. Here, the frequency range of the receiving signal of the sensor should include the frequency range of the percussion shock wave. In order to ensure the reliability of the reception and expand t...

The invention provides a method for detecting information of survivors in mine disasters. Specific to the inconvenience in transmitting underground and ground information in case of mine disasters, the invention provides a scheme for transmitting information through shock waves by taking an existing metal pipeline network in a mine area as a transmission medium and detecting survivors in mine holes in a way of detecting the shock waves generated by knocking metal pipelines in the mine holes by taking a plurality of ground sensors as receiving units. According to the method, the presence of trapped people can be determined reliably by detecting the shock waves generated by knocking the metal pipelines.
Description
technical field [0001] The invention belongs to weak signal detection and processing technology. Background technique [0002] Since the beginning of the 21st century, the research and development of human life search and positioning technology and equipment has attracted the attention of many countries, and some developed countries even passed legislation or took other measures to implement it. Due to the frequent occurrence of natural disasters and mining accidents in our country, how to make a breakthrough in the field of rescue equipment has become a new topic. [0003] Taking the coal industry as an example, because the location of the mine is buried deep underground and the stratum structure is complex, it is difficult for conventional electronic information to penetrate the bottom layer and transmit it to the ground. On the other hand, underground equipment is usually easily damaged during earthquakes. The timely discovery and rescue of survivors has brought difficul...
