摘要
该文旨在比较区间测速系统和雷达测速技术在车辆速度监测方面的计量特点,并探讨它们的优缺点以及发展趋势。区间测速系统通过车辆经过两个测速点之间的距离和时间来计算速度,具有较高的准确性和非接触式的特点,适用于需要测量多辆车辆通过某一区间的速度的场合。雷达测速技术利用雷达波的多普勒效应来实时测量车辆的瞬时速度,具有灵活性和广泛适用性。然而,雷达测速技术在计量准确性和多车辆测速能力方面存在一定局限性,并且容易受到外部干扰等影响。文章通过比较计量准确性、检测范围和适用环境、外部干扰和影响,以及多车辆测速能力等方面,全面评估了区间测速系统和雷达测速技术的优劣。此外,还探讨了两种技术的发展趋势,包括技术改进和创新,以及应用领域的拓展和需求变化。研究结果对于交通管理和安全控制提供了决策支持和技术参考,推动测速技术的进一步发展和应用。
This paper aims to compare the measurement characteristics of the interval speed measurement system and radar speed measurement technology in vehicle speed monitoring,and discuss their advantages,disadvantages and development trends.The interval speed measurement system calculates the speed by the distance and time between two speed measurement points when the vehicle passes through.It has high accuracy and non-contact characteristics,and is suitable for occasions where it is necessary to measure the speed of multiple vehicles passing through a certain interval.Radar speed measurement technology uses the Doppler effect of radar waves to measure the instantaneous speed of vehicles in real time,which has flexibility and wide applicability.However,radar speed measurement technology has certain limitations in multi-vehicle speed measurement capability and is susceptible to external interference.This paper comprehensively evaluates the advantages and disadvantages of interval speed measurement system and radar speed measurement technology by comparing measurement accuracy,detection range and applicable environment,external interference and influence,and multivehicle speed measurement capability.In addition,this paper also discusses the development trends of the two technologies,including technological improvements and innovations,as well as the expansion of application fields and changes in requirements.The research results provide decision support and technical reference for traffic management and safety control,and promote the further development and application of speed measurement technology.
