Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0033] Embodiments of the present invention provide a coal-rock destruction electromagnetic radiation direction-finding and positioning system, such as figure 1 As shown, the system includes: a three-axis electromagnetic sensor array, a signal acquisition module and a direction finding and positioning terminal;
[0034] The three-axis electromagnetic sensor array is composed of at least four three-axis electromagnetic sensors, which are used to synchronously perceive the magnetic field strength in the three-axis direction based on the tunneling magneto-resistance technology, and measure the real magnetic field vector in space;
[0035] The signal acquisition module is used to collect the magnetic field vector change information of mult...
