摘要
非接触式光电速度计是用于汽车行驶速度、距离等参数检测的重要计量器具,是标准测速仪的一种。文章介绍了标准测速仪的种类,以及非接触式光电速度计的工作原理,实验分析非接触式光电速度计测速的影响因素,并提出了合理的解决方法。
The non-contact photoelectric speed meter is an important measuring instrument used for the detection of parameters such as the vehicle＇s driving speed and distance,and it is one of the standard speedometers. The thesis introduces the different types of standard speedometers and working principles of non-contact photoelectric speedometers. The factors affecting the speed test by using non-contact photoelectric speedometers are experimentally analyzed and reasonable solutions are proposed.
