摘　　要：为了解决倾角传感器传统手工校准方法成本高、效率低和精度低等问题,设计了一种倾角传感器自动校准系统。分别对该系统的硬件设计、软件设计以及校准算法三部分进行了阐述。硬件设计主要包括ATmega128微处理器模块设计、CH340串口转换模块设计、ADM3251 RS-232收发器模块设计、有源晶振模块设计以及电源模块设计;软件部分主要是上位机的程序设计;校准算法部分介绍了最优精度算法对数据进行处理的过程。最终对单轴倾角传感器进行了校准实验,实验数据表明,自校准系统相比于传统手工校准方法精度高,校准误差缩小了近1个数量级。In order to solve problems in traditional manual calibration methods for title sensors, such as high cost, low efficiency and low accuracy, a kind of automatic calibration system is designed in this paper. The system is expounded in three parts - hardware design, software design and calibration algorithm. The hardware part includes the design of microprocessor ATmega128 module, CH340 serial interface conversion module, ADM3251 RS232 transceiver module, active crystals module and power supply module .The software part is mainly PC program. The data processing with optimal accuracy algorithm is introduced in the part of calibration algorithm. Finally calibration experiments of single-axis title sensor are operated. The experimental data show that the automatic calibration system has higher precision compared with the traditional manual calibration methods and the calibration error is reduced nearly one order of magnitude.
