Abstract

The invention discloses an attitude angle detection apparatus for suspension platforms. The attitude angle detection apparatus comprises two vertically-arranged optical autocollimators fixed under anexperimental platform, wherein the two optical autocollimators are respectively arranged opposite to light through holes in the outer wall of a laboratory and reflection mirrors on a building wall, the two optical autocollimators emit light beams and real-timely receive the reflected light beams passing through the light through holes and the reflection mirrors, and the attitude angle changes of the two optical autocollimators are detected and analyzed through a communication host computer according to the relative movement between the two groups of the reflection light spot positions detectedby the two optical autocollimators and the incident light spot position so as to indirectly reflect the course angle, pitch angle and roll angle changes of the suspension experimental platform. The attitude angle detection apparatus of the present invention has advantages of high detection precision, good real-time performance and simple detection structure.

Description

technical field [0001] The invention belongs to the field of attitude detection of an experimental platform, and in particular relates to an attitude angle detection device of a suspended platform. Background technique [0002] The high-stability, low-vibration detection platform is the measurement benchmark for high-precision accelerometer and high-precision gyro parameter evaluation, and is one of the key core technologies for the design and production of high-precision inertial devices in my country, providing reliable detection means for high-precision navigation equipment. With the development of science and technology, the design and production accuracy of accelerometers and gyroscopes is getting higher and higher. At the same time, military and civilian navigation have higher and higher requirements for the accuracy and reliability of the inertial period, which urgently requires an inertial device. And reliability evaluation means, it is required to realize simple, re...
