快速汽车前照灯测试系统的设计

Design of fast measurement system of automobile headlamps

前照灯是车辆必不可少的电气设备。对前照灯的评价就成为了十分重要的工作。介绍了汽车前照灯配光性能测试中的各测试点及区域的含义,在分析现有检测系统的基础上,提出了一种采用多探头测量的新的快速测试方法。整个系统通过软硬件相结合,形成一个集机械、电子、计算机于一体的系统。该方法在保证测量精度的同时,极大地提高了测量的速度。将详细介绍该测试系统的原理,各部分结构。

<Abstrcat>Head-lamp is a necessary electric equipment of vehicle. This article presents the inspecting points and zones in photometric measurement of motor vehicle head-lamps. A new fast testing method is introduced. This method uses a suit of detectors, improves the measuring speed and keeping the precision. The whole system contains software and hardware. It's a system combines mechanism, circuitry and computer. The article gives the principle of this test system and the structure of every part.
