随着科学技术的进步,角度检测在现代工业体系中占有重要地位。现有角度检测设备因其测量范围、测量精度和功耗等局限,而逐渐不能满足测量要求。采用石英挠性加速度计传感器、AD7734与ARM MCU组合而成的一种新型倾角测量仪,通过对石英挠性加速度计的电流信号进行调理和AD采集,以及对采集的数据进行滤波处理,解算出倾角,通过标准RS485通信接口将数据传输到PC机上显示。实验表明:在0°~30°角度测量范围内,该系统倾角测量精度可以达到±0.01°,具有很好的工作稳定性。同时,该倾角测量仪具有体积小、精度高、重量轻、功耗低等优点,可广泛应用到桥梁架设、国防军事、地质勘探、土木工程、石油钻井、航空航天、航海、精密加工等领域。
With the progress of science and technology, angle detection occupies an important position in the modern industrial system. The existing angle detection equipment can not satisfy the measurement requirements due to the limitation of measurement range, measurement accuracy and power consumption. The quartz accelerometer sensor with quartz, AD7734 and ARM MCU combination of a new type of inclinometer, through the quartz flexible accelerometer current signal conditioning and AD acquisition, and the data collected by the filter solution to solve Inclination, through the standard RS485 communication interface data transmission to the PC display. Experiments show that: in the 0 ° ~ 30 ° angle measurement range, the system can measure the angle accuracy of ± 0.01 °, with good working stability. At the same time, the dipmeter has the advantages of small size, high precision, light weight and low power consumption, and can be widely applied to the fields of bridge erection, national defense, geology exploration, civil engineering, petroleum drilling, aerospace, marine navigation and precision machining .
