Abstract

The invention relates to an integrated small-size laser gyroscope inertia measurement device which comprises a case, a cover plate and a body assembly, wherein the body assembly is mounted in the case and is sealed by the cover plate; the body assembly comprises a body seat, three laser gyroscopes, three quartz accelerometers, a functional circuit board and shock absorbers; the body seat is of a hexahedron structure; a plurality of cavities are formed in one side close to the hexahedron structure; the three laser gyroscopes are respectively mounted in the cavity a, the cavity b and the cavity c; the three quartz accelerometers are mounted in the cavity d; the cavity e is formed in the other side close to the hexahedron structure and is used for holding an accelerometer circuit board, a temperature control circuit board, a computer circuit board and a signal transferring circuit board; a power circuit board is mounted on one side wall of the hexahedron structure of the body seat; the shock absorbers are mounted at eight vertexes of the hexahedron structure of the body seat. The measurement device is compact and reasonable in whole layout, novel in style, small in size and light in weight, and has high shock absorption and impact prevention performance.

Description

technical field [0001] The invention relates to an integrated small laser gyro inertial measurement device, which belongs to the technical field of inertial navigation. Background technique [0002] The inertial measurement device ("inertial group" for short) is the core component of the inertial navigation system. Its performance determines the overall performance of the inertial navigation system. It is widely used in military and civilian systems such as rockets, missiles, aircraft, ships, and oil drilling surveys. middle. [0003] Commonly used inertial groups include body, functional circuit board and chassis. The main body contains sensitive components such as gyroscope and accelerometer, and the main body is installed in the chassis. For the inertial group main body of different precision levels, the accuracy requirements of the gyroscope are different, and the size difference is also large. In addition, a series of functional circuit boards, such as computer boards...
