Novel Method of Detecting Position in a Maglev Vehicle Using Collection Rail Characteristics

By analysis of the Resistance Characteristic of collection rail, this paper put forward a new location method for urban rail transit. In the method, train is regarded as a load. Through the study of current circuit made up of train and collection rail, the analytical formula and design scheme to realize location method is developed. Three Topological Structures based on which are compared .Through using in current 10 meter maglev train model ,the new method is verified and came into use ,because of it's low-cost , easy maintenance, and indoors setting,. It can be used as a useful complement to existing train positioning scheme.
