Embodiment 1
[0046] Embodiment 1 provided by the present invention is the first embodiment of the sensor unit in a hemispherical resonant gyro inertial measurement component with redundant configuration provided by the present invention, as figure 1 with figure 2 Shown are respectively a disassembled and assembled structural diagram of Embodiment 1 of a sensor unit provided by the present invention.
[0047]In Embodiment 1 of a sensor unit provided by the present invention, the sensor unit is arranged obliquely, specifically, as image 3 Shown is a schematic diagram of the skew principle of Embodiment 1 of a sensor unit provided by the present invention.
[0048] Specifically, by figure 1 , figure 2 with image 3 It can be seen that the sensor unit 2 is arranged on the body 1, and the body 1 adopts a split design, including a left body 11 and a right body 12, and the sensor unit 2 includes a hemispherical resonant gyro 21 and an accelerometer 22, and the number of hemispherical reson...
Embodiment 2
[0055] Embodiment 2 provided by the present invention is the second embodiment of the sensor unit in a redundantly configured hemispherical resonant gyro inertial measurement component provided by the present invention, as Figure 4 , Figure 5 with Image 6 Shown are schematic structural diagrams of the first viewing angle, the second viewing angle and the third viewing angle of Embodiment 2 of a sensor unit provided by the present invention, respectively. In Embodiment 2 of a sensor unit provided by the present invention, the sensor units are arranged orthogonally.
[0056] Depend on Figure 4 , Figure 5 with Image 6 It can be seen that in the second embodiment of a sensor unit provided by the present invention, the sensor unit 2 is arranged on the body 1, the sensor unit 2 includes a hemispherical resonant gyroscope 21 and an accelerometer 22, and the number of the hemispherical resonant gyroscope 21 and the accelerometer 22 is 6. The main body 1 includes gyro mount...
Embodiment 3
[0062] Embodiment 3 provided by the present invention is an embodiment of a redundantly configured hemispherical resonant gyro inertial measurement component provided by the present invention, such as Figure 7 Shown is a principle schematic diagram of a hemispherical resonant gyro inertial measurement component with redundant configuration provided by the present invention.
[0063] Depend on Figure 1-Figure 7 It can be known that the inertial measurement assembly includes a body 1 and a sensor unit 2 arranged on the body 1, a HRG (Hemispherical Resonator Gyro, hemispherical resonant gyro) circuit unit 3, an Acce (accelerometer, accelerometer) circuit unit 4 and a data signal processing unit 5 . The sensor unit 2 includes a hemispherical resonant gyro 21 and an accelerometer 22 . The main body 1 includes gyro mounting surfaces equal in number to the hemispherical resonant gyroscopes 21, and each hemispherical resonant gyroscope 21 is arranged on a corresponding gyroscope m...
