Introduction

Detector is a device that detects some useful information in the wave signal. A device used to identify the presence or change of a wave, oscillation, or signal. A geophone is usually used to extract the information it carries. The geophone is divided into envelope geophone and synchronous geophone. The output signal of the former corresponds to the envelope of the input signal, which is mainly used for the demodulation of standard amplitude modulation signals. The latter is actually an analog multiplicator, and in order to get the demodulation effect, it is necessary to add an additional oscillating signal (coherent signal) that is exactly the same as the carrier of the input signal. Synchronous detector is mainly used for demodulation of single sideband amplitude modulation signal or residual sideband amplitude modulation signal.

Seismometer is composed of permanent magnet, coil and spring. Magnet has strong magnetism, which is the key component of seismometer. The coil is made of copper enamelled wire wound on the frame and has two output terminals. It is also the key component of the seismometer. The spring is made of a special phosphor bronze shape with a linear coefficient of elasticity. It connects the coil to the plastic cover and forms a relative motion (inertia) between the coil and the magnet. When there is mechanical vibration on the ground, the coil does relative motion to the magnet and cuts the magnetic force line. According to the principle of electromagnetic induction, the induced electromotive force is generated in the coil, and the size of the induced electromotive force is proportional to the relative motion speed of the coil and the magnet. The analog electrical signal output by the coil is consistent with the speed change law of the mechanical vibration on the ground.
