Bus arrival detection method and system based on active RFID technology

The invention provides a bus arrival detection method based on an active RFID technology. Two RFID readers and an electronic bus-stop board main control unit are mounted on each bus, wherein the two RFID readers include a first RFID reader and a second RFID reader; an RFID electronic label is mounted at the outer side of the body of each bus. The bus arrival detection method based on the active RFID technology includes the following steps that 1, the bus pulls in, and the first RFID reader reads electronic label data of the RFID electronic label; 2, the second RFID reader reads the electroniclabel data of the RFID electronic label; 3, the electronic bus-stop board main control unit is used for receiving the electronic label data read by the first and second RFID readers and conducting algorithm processing on the electronic label data, and therefore which station and which direction the bus is located at are judged. The invention further discloses a bus arrival detection system basedon the active RFID technolo
