基于C8051F340驱动与采集的CCD光电遥测垂线仪

CCD photoelectric telemetering pendulum coordinometer based on C8051F340 with functions of driving and collection

介绍了一种CCD光电遥测垂线仪单片机驱动与采集的实现方法,利用C8051F340单片机完成对线阵CCDTCD1702C的驱动和检测,并对光路引起的测值非线性做了非线性曲线修正,大大提高了观测精度,该产品与专用的垂线配套使用可对大坝不同高程的水平位移变化进行精密测量。

The paper introduces a method for realizing the driver and signal collection of CCI2 photoelectric telemetering pendulum coordinometer by using of SCM. C8051F340 SCM is adopted for the drives and tests of line array CCD TCD1702C, and the nonlinear curve rectification is carried out for the measured value deviation caused by light path. The method improves the measurement accuracy greatly, and the product requires a specialized plumb line to make a precise measurement of the hor- izontal displacement variation of the dam.
