基于激光三角法的单片机检测系统研究
|
摘要
传统单片机检测方法通常是接触式检测,但是随着社会的进步,这种方法逐渐被非接触式检测取代。因此,采用非接触式检测方法设计基于激光三角法的单片机检测系统。所设计的系统研究了激光三角法的检测原理,讨论了检测最优解的获取方法,并以螺纹量规为例,研究了单片机激光三角法检测结构设计方案以及单片机在选型上的参数要求,给出基于激光三角法的螺纹量规检测计算实例。此外,系统还对单片机检测接口与硬件抗干扰措施进行了介绍,达到了增益系统性能的目的。实验结果表明,基于激光三角法的单片机检测系统能够准确检测物体参数,其检测结果与真实值几乎一致。
The detection methods of traditional SCM are usually contact method. With the development of the society,this method is gradually replaced by non-contact detection. Therefore,this paper proposed using non-contact detection method to design single chip microcomputer testing system based on laser triangulation. The detection principle of laser triangulation was studied,the access way of optimal detection was discussed,and studied the detection structure design plan of SCM laser triangulation method and the parameters requirements of single-chip computer selection to give out the detection calculation example of thread gauge based on laser triangulation. In addition,the detection interface and anti-jamming measurements of hardware were also introduced to gain the system performance. The experimental results show that the single-chip microcomputer detection based on laser triangulation can accurately detect the object parameters,and the test results are nearly close to the real value.
