Piezoelectric gyroscope

Piezoelectric gyroscope is a product of computer popularization and piezoelectric sensor technology development. Typical features are: measuring probe circuit is simple and reliable, only accurate to collect the sensor response value (electrical signal), communication, by the ground computer memory, storage data, And then parsing and statistical processing of these data, and finally converted into the required data form and as a useful information output. Ground handling software takes up most of the technical content of the entire measuring instrument. This soft and hard on the technical means has become increasingly mature.

The piezoelectric gyroscope consists of two accelerometers in the x, y direction and a piezoelectric crystal angle meter. The xy plane is parallel to the rotational plane measured by the crystal angle meter and perpendicular to the axis of the probe. Its starting azimuth (same as the mechanical gyroscope) is determined by the compass on the ground and input to the computer for memory; when the probe is rotated, the piezoelectric crystal angle meter outputs a voltage equivalent to the rotation angle, after the analog-to-digital conversion Sent to the ground computer, while the two components of gravity also sent to the computer for memory.
