| High-speed magnetic levitation(MAGLEV) train is an effective,economic and safety communication technology. How to make high-speed magnetic levitation train commute safety is the key point of building and developing a high-speed magnetic levitation train system. Thereinto, the safety,reliability,simultaneous of data transfers very important. The information can transfer smoothly by using subarea safety data transfer system, reconciling speed and distance of the train to avoid narrow speed between trains. So, it is very important to keep safety of the whole magnetic levitation system. The aim of this project is that by using a complete safety way of transferring information, both from the safety of hardware and software to complete the transference of the important information.This thesis has discussed the practical meaning of the project and development presence of operation control system safety transfer network, base on this, we study transwork that can assure data transfer to neighbouring subarea by safety computer. We designed data transfers system base on double fiber ring framework by referencing correlative criterion of railway signal system. |
