Acoustic magnetic synchronization method

It is a comprehensive application of acoustic measurement and electromagnetic wave method, such as the DTC series acoustic magnetic synchronous fixed-point instrument, which adopts the fixed point principle of combining acoustic measurement and acoustic magnetic synchronous fixed-point method. When the acoustic measurement method is used to fix the point, the acoustic head of the fixer indicates the Seismic wave received by the acoustic probe, and the earphone also reflects the seismic sound wave received by the acoustic probe. Directly above the fault point, the acoustic signal is at its maximum. When leaving the fault point, the acoustic signal decreases or there is no acoustic signal. When the acoustic magnetic synchronization method is used for fixed points, the sound meter head reflects the seismic sound waves received by the acoustic probe, and the magnetic meter head and earphones simultaneously indicate the electromagnetic waves received by the antenna when the fault point is discharged. When the sound measuring probe is placed above the fault point, the two meter heads of the fixer indicate and the earphone sound is synchronized. When the acoustic signal is not received, the use of the acoustic magnetic synchronous electromagnetic wave reception function can timely grasp the discharge rhythm of the ball gap, which is conducive to identifying weak acoustic signals at fault points in noisy environments. In addition, the acoustic magnetic synchronous locator can synchronize the fault location and cable path detection work, greatly improving the efficiency of fault location.
