Compound intelligent vibration sensor and vibration source test and location method

The invention relates to a compound intelligent vibration sensor and a vibration source test and location method. The sensor consists of a spherical structure and an intelligent control system. The spherical structure comprises a spherical shell, encapsulating material, an external interface, a power and signal conditioning circuit board and the like; the intelligent control system comprises a three-axis magnetoresistive sensor for testing attitude, a three-axis acceleration sensor for testing attitude, a low-range three-axis acceleration sensor for testing vibration, a high-range three-axis acceleration sensor for testing vibration, a microcontroller, a serial communication unit, a conditioning amplifier, an anti-alias filter, a voltage follower, a charge amplifier, a power module and the like; and the vibration source test and location method can realize high-precision underground vibration source location. The sensor and the vibration source test and location method can be used for coal seam goaf monitoring, tunnel hole detection and the location of impact points in ranges and other various vibration sources as well as the research of the related theory of stress waves in a vibration test field.
