摘　　要：利用低功耗、高性能的STC12C5A60S2微处理器和三轴加速度计传感器ADXL330,设计了一款倾角测量装置。详细介绍了利用加速度计测量倾角的原理,重点阐述了系统的硬件电路设计以及算法研究。测量结果显示,角度在-60°～60°范围内,其测量误差在0.3°以内。该系统集成度高、体积小、可靠性高,可用于各类飞行器的倾角指示和测量。A new tilt-sensor with STC12C5A60S2 microprocessor and triaxial accelerometer ADXL330 is designed. The principle of tilt detecting is analyzed by using an accelerometer.The design of hardware circuit and the study on algorithm are expounded.The measuring results indicate that the measurement error is less than 0.3°when the angle changes within -60°to 60°.The characteristics of this system is the high-integration, small volume,fast responding speed,high reliablity,which is used in all kinds of vehicle＇s angle indicator and measurement.
