分析了振动传感器横向灵敏度校准原理及引起校准误差的主要原因 ,研制了以单片机为控制核心的数据处理系统 .该系统可自动完成加速度传感器校准数据的采集、处理、运算、显示和打印等功能 ,最大限度地减小了X ,Y ,Z加速度计取数时间延迟造成的误差 ,消除了人工读数误差 ,提高了数据处理的精度 .利用数据处理系统对丹麦B&K公司生产的 4 384型加速度计校准 ,进行软、硬件功能的综合调试 ,自动校准结果为Tmax=1 .0 5% ,θmin=1 5.3° ,接近出厂标定值Tmax=1 .0 0 % ,θmin=1 5.0° .

Adjusting principle of the transverse sensitivity of vibratin g sensor and main cause of adjusting error are analyzed, and the data processing system that is based on single chip microcomputer is developed. In the system, The function of collecting, processing, calculating, showing, drawing and printi ng the data which come from accelerometer sensor's calibration can be completed automatically. It decreases the error to the least limit which result from time' s delay in the course of which X,Y,Z accelerometer obtains data, eliminates the error caused by man's distinguishing data, increasing the data handling accu racy . The data is 8used in handling system to adjust 4384 type accelerometer pr oduced by Denmark B&K company, in order to debug the hardware's and software's a ll function, The result of adjusting automatically is that T max =1.05% , θ min =15.3°, more near to result estimated by the maker T ma x =1.00%, θ min =15.0°.
