Problems solved by technology

There are two common ground tilt observations: horizontal pendulum and vertical pendulum. Horizontal pendulum tilt observation has high sensitivity, but it is easily disturbed and has poor stability, which makes the measurement accuracy not high.
The vertical pendulum inclinometer uses the principle of plumb. It has a simple structure and stable performance, and is widely used. However, the existing vertical pendulum inclinometer has a narrow dynamic range, a narrow response frequency band, and unsatisfactory damping effects. Due to the pendulum phenomenon, the data is discontinuous, and the output linearity of the vertical pendulum inclinometer is low.
And in the observation environment in the process of urbanization, there are interference sources such as industry and traffic, and it is difficult to find a site that meets the installation conditions, which greatly restricts the existing vertical pendulum tilt observation

Abstract

The invention discloses a ground tilt monitoring device .The ground tilt monitoring device comprises a device shell, a suspension frame and a processing circuit board are arranged in the device shell, two capacitive sensors are orthogonally arranged on the suspension frame, each capacitive sensor comprises capacitor stators, capacitor rotors and pendulum bobs, the capacitor stators are arranged on the two sides of the capacitor rotors at equal intervals, the capacitor stators and the capacitor rotors are horizontally arranged on the same horizontal plane, the capacitor stators are arranged on the suspension frame, the pendulum bobs are arranged on the suspension frame in a hanging mode and arranged on the lower portions of the capacitor rotors to be in rigid connection with the capacitor motors, the capacitive sensors are electrically connected with the processing circuit board respectively, and a zero setting mechanism is further arranged on the suspension frame .According to the ground tilt monitoring device, when zero setting is conducted, the two capacitive sensors do not influence each other, the pendulum bobs drive the capacitor rotors to move to change the space between the capacitor rotors and the capacitor stators so as to produce capacitance variable quantity, and the influence of static friction force of pendulum bobs in the prior art is eliminated; the ground tilt monitoring device is mainly used for monitoring earth tides, earthquake precursors and tilting deformation of an earth crust, and the ground tilt monitoring device is simple in structure, good in stability, high in precision and high in output linearity.

Description

technical field [0001] The invention relates to the technical field of precision measuring devices, in particular to a device for monitoring solid tides, earthquake precursors and the tilt deformation of the earth's crust. Background technique [0002] As a geodynamic instrument, the tilt monitoring device plays an important role in the observation and research of crustal deformation and the prediction of earthquakes and solid tides. Since the 1970s, the tilt observation has been widely carried out in our country. There are two common ground tilt observations: horizontal pendulum and vertical pendulum. Horizontal pendulum tilt observation has high sensitivity, but it is easily disturbed and has poor stability, which makes the measurement accuracy not high. The vertical pendulum inclinometer uses the principle of plumb. It has a simple structure and stable performance, and is widely used. However, the existing vertical pendulum inclinometer has a narrow dynamic range, a narro...
