移动式出租车计价器自动检定装置的研究

Research of Movable Taximeter Automatic Verification Device

传统的滚轴式出租车计价器检定需在固定场所进行,且滚轮打滑和震动都会带来测量误差,文中研制了一款基于激光多普勒原理的出租车计价器自动检定装置,符合国家规程JJG 517-2016 《出租汽车计价器检定规程》中行车测距法的相关规定,具有无需固定场所、便携可移动和建项成本低等优点。经过试验验证,表明该装置检测准确度高且稳定性好。

Traditional roll type taximeter verification needs to be done in fixed place, and roller skidding and vibration could cause measuring error. So a taximeter automatic verification device based on laser doppler theory is introduced in this paper, which fitted the rules of Taximeters. The device could be used in different places and cost less than before. According to experiments, it is indicated that this device has high accuracy and stability.
