[0027] The present invention will be further described below with reference to the drawings and embodiments.
[0028] Refer to the attached drawings:
[0029] The method of identifying and receiving highway EWM data packets based on RFID tags, the steps are as follows:
[0030] Step 1: Install RFID transponders at each entrance of the expressway. The transponder contains the ID information of the expressway and the related driving distance information from the beginning of the expressway to the transponder. The road ID information of different driving directions on the same expressway is different.
[0031] Step 2: When the vehicle passes through the road entrance where the RFID transponder is installed, the reader installed on the vehicle reads the highway ID information and mileage information in the transponder.
[0032] Step 3: The vehicle-mounted central processor effectively processes and records the acquired ID information and driving distance. At the same time, the recorded dr...
