摘要
为了研究一种精确测量公路机动车行驶速度的新方法,避免交通管理部门对机动车驾驶员的错罚和漏罚,以AT89S52为控制核心、以激光二极管为传感器,设计了一套测速系统。经过现场对比实验和理论误差分析,得到了其测速相对误差达到0.1%数量级的结果。结果表明,这将为交通管理部门提供一种新的、精确的公路机动车现场测速装置,也可为雷达测速仪和反射式激光测速试验装置等现场测速仪器提供一种精确的校准装置。
In order to develop a high-precision speedometer so that the mistake and missing punishment of the traffic administration can be avoided, a laser speedometer with a diode laser source was designed based on AT89S52 single-chip microcomputer. Comparing the field test results with the theoretical one, the relative error was 0.1% order of magnitude. It not only supplies a kind of new precise speedometer to measure the instant speed of vehicles on the road, but also supplies a new calibration instrument for radar speedometers and reflex laser velocimeters.
