| Abstract: | Based on the operation characteristics of the maglev train, this paper summarizes the existing data collection methods, analyzes the optical characteristics of fiber grating, and develops a theory that uses the fiber grating sensor to gather maglev train operation data. Furthermore the paper raises a fiber grating sensor structure for maglev train data collection and explains in theory the working mode of the structure. Experiment results indicate that the stress characteristics of fiber grating can satisfy the needs of maglev train locating. |
