针对飞机尾翼转角测量及远距离监控问题,设计了一种基于数字式MEMS加速度传感器测量飞机尾翼转角的测量系统。分析了电容式加速传感器测角原理；利用数字式MEMS加速度传感器ADXL345,结合无线ZigBee技术采用CC2430模块,以嵌入式STM32单片机作为控制器构建了一种测量飞机尾翼转角大小的测量系统。采用三维转台对飞机尾翼转动进行了模拟,完成了±90°范围内转角的测量。实验结果表明,在±90°转角范围内,测量误差的最大值为0.277°,满足小于0.3°的误差要求。该测量系统可以有效地完成飞机尾翼转角测量工作。

Design of aircraft rudder rotational angle measurement system

Aiming at questions of aircraft rudder rotational angle measurement and remote monitoring, an angle measurement system for aircraft rudder based on digital MEMS acceleration sensor is designed. Using digital MEMS acceleration sensor, combined with wireless module of CC2430 ZigBee, and taken embedded STM32 microcontroller as the central controller, the angle measurement system for aircraft rudder is established. Aircraft rudder rotational experiment is simulated by using 3D turntable, and angle measurement is achieved within -90° to +90°. Experiment results show that within ± 90 ° rotation angle ranges, the maximum error is 0.277°, less than 0.3°, which meets the requirement of measurement. The angle measurement system can effectively complete aircraft rudder angle measurements.
