| Abstract: | A new looped-cable induction systems is designed to overcome the traditional inductive radio's disadvantages, and is used for train locating, speed measuring and data transmission. Based on this new system, an electromagnetic model is established, which proves that the communication channel between antenna and rail cable is invariable. This system can not only be used for the train-ground communication,but also be used for train locating and speed measuring. Then the anti-disturbance capacity of the new system is analyzed, a simulation program is accomplished based on the displacement disturbance that the system has to face. Finally, tested in maglev train communication system, also in train locating and speed measuring system, the expected effect of this new system is achieved. |
