Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and discloses an inertial measurement device, which includes a casing, a sensing component and a shock absorbing component installed in the casing, and the sensing component includes an integrated circuit board and an inertial sensor connected to the integrated circuit board and The air pressure sensor; the shock absorbing assembly includes a first shock absorbing pad, a first weight increasing block, a second weight increasing block and a second shock absorbing pad which are connected in sequence; The accommodating cavity of the integrated circuit board, the accommodating cavity accommodating the inertial sensor and the air pressure chamber accommodating the air pressure sensor and communicating with the outside are arranged on the first weight block. By setting the accommodating cavity and the air pressure chamber on the first weight block, on the one hand, it can provide a space for placing the inertial sensor and the air pressure sensor, so that the whole inertial measurement device can be more integrated; on the other hand, it can reduce the impact of external factors on the inertial sensor and The measurement interference of the air pressure sensor improves the measurement accuracy of the inertial measurement device.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an inertial measurement device and an unmanned aerial vehicle. Background technique [0002] The inertial measurement unit is the core module of the UAV control system. By analyzing the data measured by the inertial sensor and the air pressure sensor, the attitude information and position information of the UAV can be obtained, so as to realize complete self-navigation. [0003] In the field of UAV aircraft, the main mechanical environment faced by the inertial measurement device during operation is the severe random vibration of the UAV. The vibration will not only make the output signal of the inertial measurement device noisy during measurement, but also cause data distortion and reduce measurement accuracy. And it is easy to cause damage to electronic components. [0004] In addition, during the flight of the unmanned aerial vehicle, due to the high maneuver...
