Abstract

The invention provides a control circuit of an attitude sensor. The control circuit comprises a control module, and a voltage stabilizing module, a motion processing module and an output module whichare connected with the control module. The voltage stabilizing module comprises a first control chip U1 and a first capacitor C1; an IN pin of the first control chip U1 is connected with a +5V power supply; an OUT pin of the first control chip U1 is connected with one end of the first capacitor C1 and a node VCC, and the other end of the first capacitor C1 is grounded; a GND pin of the first control chip is grounded; and the node VCC is connected with the control module and the motion processing module. The +5V voltage is reduced to 3.3 V through the first control chip U1, so that power is supplied to the control module and the motion processing module; and through the effect of the voltage stabilizing module, the voltage of other modules can be stabilized, so that the normal work of othermodules is effectively guaranteed, the problems of data jumping, data instability, serious data sawtooth waves and the like are effectively avoided, and the stability of the attitude sensor is effectively improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of attitude sensors, and in particular, to a control circuit of an attitude sensor. Background technique [0002] The attitude sensor is a high-performance three-dimensional motion attitude measurement system based on MEMS technology. It contains three-axis gyroscope, three-axis accelerometer, three-axis electronic compass and other motion sensors, and obtains temperature-compensated three-dimensional attitude and orientation data through the embedded low-power ARM processor. Using the quaternion-based 3D algorithm and special data fusion technology, the zero-drift 3D attitude and orientation data represented by quaternion and Euler angles are output in real time. LPMS series and iAHRS-M0 attitude sensor can be widely embedded in model aircraft drones, robots, mechanical gimbals, vehicles and ships, ground and underwater equipment, virtual reality, human motion analysis and other produ...
