| Abstract: | The characteristics of the techniques of the locating and speed-measuring for aerotrain are introduced. Emphases are put on the applications of the counting method of the crosstie and rail cable and the device for determining the absolute position to train locating and speed measuring. Principles and methods of these applications are given, and the source of error is analyzed. Based on these analyses, and taking the current status of maglev in our country into account, solutions of train location and speed measuring for the current stage are provided and relevant test results are given. |
