【Abstract】 The technology of speed measurement and positioning of the magnetically levitated(maglev)train plays a vital role in its operation safety and transportation efficiency. In view of this,a new type of 3 D trackside positioning and identification technology for magnetic-coded train is proposed based on the status of research and development at home and abroad. The permanent magnet magnets are adopted to represent the corresponding values,which are combined to generate train positioning information identification codes,and the corresponding magnetic code identification methods are given. And then,the vehiclemounted magnetic code decoder reads the information to realize the speed measurement and positioning of the traveling maglev train. In comparison with the existing methods of train positioning,the proposed identification code has several advantages,including simple structure,low cost,high precision and easy installation & maintenance,which provides a certain reference for the future development of high-speed maglev train.更多还原
