路侧设备与车载单元进行数据通信的方法和系统
摘要：
本发明实施例提供了一种路侧设备与车载单元进行数据通信的方法和系统。该方法主要包括：将路侧设备设置在路径上，所述路侧设备在其发射时隙广播所述路径信息；设置在车辆上的车载单元接收到所述路侧设备广播的路径信息后，将所述路径信息进行存储；所述车载单元延时固定时间间隔后，在所述路侧设备的接收时隙向所述路侧设备发送所述车载单元的标识信息。本发明实施例通过RSU与OBU之间进行双向的数据通信，可以在RSU将OBU的标识信息和对应的路径信息进行关联，从而可以方便对OBU进行计费等处理，并且可以对路径信息对应的车辆通行情况等交通信息进行统计。本发明实施例不仅保证了RSU原有的标识成功率，而且保证了RSU的盘点率。
摘要（英）：

An embodiment of the invention provides a method and a system allowing road side unit (RSU) and an on board unit (OBU) to perform data communication. The method mainly includes: the road side unit is set on a path, wherein the road side unit broadcast path information during the transmitting time slot of the road side unit; the on board unit disposed on a vehicle stores the path information after receiving the path information broadcasted by the road side unit; after the delay of a fixed time interval, the on board unit transmits the identification information of the on board unit to the road side unit at the receiving time slot of the road side unit. The method has the advantages that by the bidirectional data communication between the RSU and the OBU, the identification information of the OBU can be associated with the corresponding path information on the RSU, processing such as OBU billing can be performed conveniently, and statistic of traffic information such as passing conditions of vehicles corresponding to the path information can be achieved; the original identification success rate of the RSU is guaranteed, and RSU check rate is guaranteed.
