摘　　要：带有加速度计的倾角传感器的温度补偿一直是影响精度的重要因素,基于反正弦法的温度补偿可以大大提高传感器的精度。设计过程中采用反正弦法计算输出角度数据,温度补偿时的数据用最小二乘法进行分析与处理。实验结果表明:通过反正弦法计算角度已经具有很高的精度;基于反正弦法的温度补偿可以使精度更高。对比实验的结果证明了该方法的有效性和可行性。Temperature compensation of tilt angle sensor with accelerometer has been an important factor to affect precision,and temperature compensation based on arcsine method can greatly improve precision of sensor. In design process,output angle data is calculated by using arcsine method,and temperature compensation data is analyzed and processed by the least square method. Experimental results show that the arcsine method for angle calculation has high precision,and temperature compensation based on the arcsine method can make precision more higher. The result of comparison experiment proves feasibility and effectiveness of the proposed method.
