Álvarez KW - Electromagnetic sensor array KW - train wheel detection AB - This work proposes a train wheel detection system based on an electromagnetic sensor array. This sensor array is distributed in points along a section of the railway. Each sensor of the ayay is located next. to the rail without additional electronics in this place. All the electronic signal process equipment is concentrated at a place far away the rail. To compensate the attenuation in the wires and the external noise, it is proposed to use a signal coded with Golay sequences. Combining the properties of the Golay sequences with the characteristics of the proposed sensor array, it is possible to detect the passage of the train by scattered points, and also to recognize the sense of circulation and estimate the speed of the train.
