Abstract

In rail transit, sensor is the main measuring tool in speed measurement and location system, which consists of Electromagnetic induction sensor, Pulse speed sensor, Accelerometer and Inertial transducer, etc. Based on the comprehensive analyses of working principle, estimating mode and installed-application of sensors, this paper reaches the conclusion that integrated Multi-sensor can provide the most accurate speed positioning data, and through the data fusion algorithm train operation control is completed; rail traffic detecting technology will be the inevitably developing tendency in future.
