Design and Realization of a New-type BSQ Inverted Pendulum Clinometer

Abstract

In the preparation and generating process of a strong earthquake, the inclinaiton changes of the ground formed by crustal structural deformation can be striking. Generally, the abnormity can greatly exceed the measuring spans of most clinometers which can be found on the market currently. This paper proposed and developed a new-type BSQ inverted pendulum clinometer aiming at solving the problems of current precursor observation instrument: Measuring spans are small, and the requirements on observation environment are strict. This clinometer is in inverted pendulum design and uses CCD sensor to monitor ground inclination variations. It is able to reduce installation cost while effectively avoiding the main influence left by ground noise. As a result, the measuring span can be increased and the ability to monitor crustal deformation can be effectively improved.
