摘要

利用一个三轴 MEMS 加速计和一个 ARM Cortex-M3 微控制器设计了一个低成本、低功耗和小尺寸的倾斜测量系统。为了提高系统的测量精度，使用了滤波技术，并提出了一种基于微控制器中嵌入的温度传感器的加速度计灵敏度随温度漂移的补偿方法。实验结果表明，倾角测量系统能以 100Hz 的速度更新倾角信息，测量误差小于 1°，倾角的标准偏差小于 0.13°，该系统已被用于一些微型无人飞行器的微型带式惯性导航系统（SINS）。

Development of a tilt measurement system based on MEMS sensor and Cortex-M3

A low-cost, low-power and small-size tilt measurement system is designed with a 3-axis MEMS accelerometer and an ARM Cortex-M3 microcontroller. In order to increase the measurement accuracy of the system, the filtering is used and a method of compensating for the accelerometer sensitivity drift with temperature is also proposed based on the temperature sensor embedded in the microcontroller. Experimental results show the tilt measurement system can update the tilt information at the speed of 100Hz, the measurement error is less than 1° and the standard deviation of the tilt angle is less than 0.13°, which has been used in a micro strapdown inertial navigation system(SINS) of some MUAV.
