为了实现倾角的测量和监测，本文设计了一种基于热对流加速度计的倾角测量系统。设计并构建了以单片机为中心的调理电路。在-90°到+90°范围内对测量系统进行了实验表征。输出结果呈非线性关系。标定结果表明，加速度计的灵敏度约为650mV/g。最大误差为5.5%，重复性误差为3%。实验证明，所开发的测量系统能够测量倾角。
For the purpose of inclination measurement and monitoring, a tilt angle measurement system using a heat convection accelerometer is presented in this study. A conditioning circuit that center around the single chip processor is designed and built. Experiments were carried out to characterize the measuring system with the range of-90° to +90°. The output results show nonlinear relationship. The calibration result indicates that the sensitivity of the accelerometer is about 650mV/g. The maximum error is 5.5% while the repeatability error is 3%. Experiments proved that the developed measurement system is capable of measuring tilt angle.
