摘要
汽车整车尺寸参数是汽车通过性参数及运行安全检测的重要内容,为了精确测量外廓尺寸参数,提出了一种基于激光光幕、超声波传感器、上位机控制软件等构成的新型车辆外廓尺寸检测方案。设计和调试了系统的软硬件,并搭建了检测试验线,对研发的系统进行了验证,试验结果表明:系统能够对不同车型的车辆外廓尺寸进行高精度、非接触、自动化测量,且运行稳定可靠,误差小于1%。解决了目前国内车辆检测机构对于车辆外廓尺寸的检测的主要采用手工测量而造成的劳动强度大、效率低、易出现人为误差等问题。
Vehicle dimensions parameters is an important part of vehicle trafficability parameters and vehicle operation safety testing. In order to accurately measure the dimension parameters, a new vehicle dimensions detection system based on laser screen, ultrasonic sensor, and upper-computer control software is designed. It designed and debugged the systemg hardware and software, and sets up test line, and the developed system was verified. Experimental results show that the system can detect the different mod- els of vehicle dimensions with high accuracy, non - contact, automated testing, have the characteristic of stabilization, credibility, and error of calculation is lower than 1%. It solves the problem of high intensity of labor, inefficiency, and human error, which caused by China＇s vehicle testing institution to test vehicle outline dimension manually.
