Problems solved by technology

The outstanding disadvantages of these old-fashioned angular rate gyroscopes in practical applications are: large size, expensive, easy to damage, low impact acceleration resistance, short life, and small measurement range (the maximum measured value of the old-fashioned angular rate gyroscope is only 500° / s) , low frequency response (up to 100Hz) and most of them do not have self-test (self-Test) functions, etc. Even today's more advanced fiber optic or laser gyroscopes are difficult to be widely used due to their high price and large size.

Abstract

The invention discloses a multi-combination angular speed gyroscope, comprising six angular speed gyroscopes for measuring the angular speed along the direction of Z axis in space, an A / D sampling circuit and a processor; wherein, the A / D sampling circuit is in charge of analog-to-digital conversion on the analog signal output by the six angular speed gyroscopes, and the processor is in charge of emerging the six digital signals output by the A / D sampling circuit and outputting an accurate and real-tine detecting signal. The invention has the advantages of simple structure, small volume, light weight, low cost and convenient use; besides, the invention has self detecting function, high reliability, long service life and wide application range.

Description

technical field [0001] The invention relates to the technical field of inertial measurement systems, in particular to a multi-combination angular rate gyroscope for measuring the angular rate of one axis in a plane coordinate system. Background technique [0002] At present, most of the angular rate gyroscopes commonly used in missile control, geological survey, industrial control, aviation vehicle stability control, strapdown inertial navigation, automotive autopilot and robot control are mechanical. , such as liquid floating or semi-liquid floating, flexible angular rate gyroscope with rotating motor, etc. The outstanding disadvantages of these old-fashioned angular rate gyroscopes in practical applications are: large size, expensive, easy to damage, low impact acceleration resistance, short life, and small measurement range (the maximum measured value of the old-fashioned angular rate gyroscope is only 500° / s) , low frequency response (up to 100Hz) and most of them do no...
