[0002] Vibrators are crucial excitation devices in land geophysical exploration and production. With the continued expansion of the exploration market both domestically and internationally, awareness of safety, efficiency, and environmental protection is growing. Vibrators, particularly in areas of heightened security, are finding increasing application due to their high efficiency, safety, and environmental friendliness. my country began developing vibrators in the 1980s, and has achieved significant success with the development of the KZ series, the LFV3 low-frequency, and the EV-56 high-precision vibrators, as well as the upcoming shear-wave vibrators. However, because the electronic control systems for vibrators span multiple disciplines and serve only the land exploration market, they are primarily monopolized by foreign countries.

[0003] With the widespread use of vibrators and oil companies' demand for efficient data acquisition from vibrators, technologies such as independent synchronous scanning, ultra-efficient aliasing acquisition, and dynamic sliding scanning have been widely adopted. The use of electronic control systems for vibrators, serving as the brain and central nervous system control unit of the vibrator, has reached a historic high. The key control technology for electronic control systems for vibrators lies in the use of attitude sensors to acquire signals from the vibrator vibrators. However, current electronic control systems for vibrators suffer from many low-frequency harmonics, high distortion, and susceptibility to interference during transmission during the construction of vibrator control. Therefore, it is of great significance to develop an attitude sensor circuit for accurately acquiring vibrator vibrator signals. Summary of the Invention
