The invention discloses an intelligent network connection roadside message packet loss rate detection method. The method comprises the following steps: S1, determining a packet loss rate maximum value Omax allowed by a packet loss rate by using a Monte Carlo method; s2, acquiring data broadcasted by the roadside unit by using a data acquisition vehicle; s3, calculating the packet loss rate O of the data broadcasted and sent by the road side unit, judging whether the packet loss rate O of the data broadcasted and sent by the road side unit is qualified or not, if O < = Omax, considering that the packet loss rate is qualified, and if Ogt, judging that the packet loss rate is qualified; and Omax is considered to be unqualified. Through the above design, accurate detection and judgment of the packet loss rate can still be realized in a state that the roadside message is shielded.
本发明介绍了一种智能网联路侧消息丢包率检测方法,包括以下步骤:步骤S1、用蒙特卡洛方法确定丢包率允许的丢包率最大值Omax;步骤S2、使用数采车采集路侧单元广播的数据;步骤S3、计算路侧单元广播发送的数据丢包率O,判断路侧单元广播发送的数据丢包率O是否合格,若O≤Omax则认为丢包率合格,若O>Omax则认为不合格。通过上述设计,本申请实现了在路侧消息有遮挡的状态下,依然能够实现对丢包率的精准检测判断。
