The invention discloses a nitrogen oxide accurate detection method and system, and the method comprises the following steps: taking a region where a to-be-detected automobile is located as a reference region, and obtaining the traffic information in the reference region; taking 100km as a preset distance length, and intercepting a route with the preset distance length from the traffic route with the maximum traffic flow as a reference route; analyzing the driving road conditions in the reference route, and calculating the proportion Kn of different driving road conditions in the reference route; standard driving speeds Vn under different driving road conditions are obtained, and standard driving time Tn required by different driving road conditions in the reference route is calculated; testing time Ts is set, testing time Tsn of different driving road conditions is distributed, testing of the different driving road conditions is carried out on the automobile, and an average value is taken as an automobile average emission concentration value after testing is completed. According to the invention, the problem of on-site driving is fully considered, and more accurate emission measurement is obtained by testing and simulating actual driving.

    本发明公开了一种氮氧化物精准检测方法及系统,所述的方法包括以下步骤:以待检测汽车所在区域作为参考区域,并获取所述的参考区域内的交通信息;以100km作为预设路程长度,从车流量最大的交通路线中截取预设路程长度的路线作为参考路线;分析所述的参考路线中的行驶路况,计算出不同行驶路况在参考路线中的占比Kn;获取不同行驶路况下的标准行驶速度Vn,计算所述的参考路线中不同行驶路况所需的标准行驶时间Tn;设定测试时间Ts,分配不同行驶路况的测试时间Tsn,对汽车进行不同行驶路况的测试,并在测试完成取平均值作为汽车平均排放浓度值。在本发明中,充分考虑了实地行车的问题,通过测试模拟实际行驶,来获取更为精确的排放测量。
