车辆检测器关键评价指标测试方法

Research of testing methods on key evaluation indexes of typical vehicle detector

鉴于目前各种类型车辆检测器的技术水平、产品标准发展参差不齐,在测试产品质量过程中存在缺乏标准、缺少操作方法等问题,该文通过分析线圈、视频、地磁、微波车辆检测器的特点及其关键评价指标,提出车辆检测器物理测试及数据评价两步测试方法,综合车辆检测器的车流量、平均速度及时间占有率评价指标性能。实验表明,所提方法可弥补目前车辆检测器产品质量中存在的问题,提高车辆检测器关键评价指标的测试能力和测试效率。

Since the current technical level and the standardization development of various types of vehicle detector is uneven,the vehicle detector test efficiency is not high,due to the lack of relevant standardization or specific operation.In this paper,by analyzing the characteristics and the key evaluation index of various types of vehicle detector,this paper proposed two steps test,the physical test and the subjective evaluation,to comprehensive test the coils,video,geomagnetism,microwave based vehicle detector in these performance aspects,such as the vehicle mount,the average speed and the time share index.It demonstrates that the proposed method solve the problem in testing vehicle detector and improve the ability and the efficiency in testing and evaluating typical vehicle detector.
