摘要
介绍了振动台测量控制系统、标定振动g值及减小标定误差的技术 .在此基础上 ,介绍了利用HP344 0 1A型数字万用表和微型计算机进行数据采集的通信技巧和编程技巧 .利用这套系统 ,对笔者联合研制开发的仪表级压阻式硅加速度计动态I/O特性进行了大量的测试标定和数据采集处理 ,得出了可靠和满意的结果 .
In this paper,we have introduced a measuring and controlling system of vibrometer;standardizing technology on g value of vibrometer and introduced especially technology to reduce the standardizing errors.On the basis,we have introduced communication and programming technique in this data acquisition with model HP34401A digital multimeter and computer.By utilizing this system ,we standardize and collect many I/O characteristic curve for instrument grade piezoresistive silicon accelerometer jointly developed by ourselves. We have obtained satisfyingly reliable results.
