Abstract:
1. A method for determining the sequence of vehicle tagged with and without an RFID (radio-frequency identification), the method comprising: f f f f if the curve a has no pulse matching the set conditions, it is judged that one or more vehicles without the RFID had driven through; there is required a manual work or other technical process to determine the total number of the vehicles and the orders; if the curve a has one pulse matched the set conditions, and it is detected by the induction coil, the vehicle speed is obtained by the curve b, which is defined as a first speed; it is read and written by the RFID, the speed is obtained by the curve a, which is defined as a second speed; if the first speed is equal to the second speed within a certain range, it is judged that a vehicle with the RFID drives through; when the first speed is not equal to the second speed in the certain range, it is judged that one vehicle with the RFID and at least one vehicle without the RFID drive through; it is needed manual or other technical process to determine the total number of the vehicles and the orders; if the curve a has two pulses matched the set conditions, when the first speed is equal to the second speed in the certain range, it is judged that two vehicles with the RFIDs drive through; when the first speed is not equal to the second speed in the certain range, it is judged that two vehicles with the RFIDs and at least one vehicle without the RFID drive through; it requires manual or other technical process to determine the total number of the vehicles and the orders; if the curve a has n (n>2) pulses matched the set conditions, when the first speed is equal to the second speed in the certain range, it is judged that n vehicles with the RFIDs drive through; when the first speed is not equal to the second speed in the certain range, it is judged that n vehicles with the RFIDs and at least one vehicle without the RFID drive through; it requires manual or other technical process to determine the total number of the vehicles and the order.
