| Abstract: | Based on analyzing the advantages and disadvantages of train positioning technologies, the RFID （ Radio frequency technology） is proposed for train positioning. The RFID train positioning control system is de- veloped by using C language The test results show that the RFID technology can achieve the positioning of the train, and it needs only 20 ms for the high-speed reader to recognize and read information from electronic tag. The accuracy of the RFID positioning is 5 cm, and it can directly distinguish the line which the trains locate a- mong multiple track rail lines and between the railroad switch. RFID has anti-interference ability, so it can be used in sandy environment and wet environment. RFID technology can also be used to test the train disconnect problem. |
