ABSTRACT
This paper studies an absolute positioning sensor for a high-speed maglev train and its fault diagnosis method. The absolute positioning sensor is an important sensor for the high-speed maglev train to accomplish its synchronous traction. It is used to calibrate the error of the relative positioning sensor which is used to provide the magnetic phase signal. On the basis of the analysis for the principle of the absolute positioning sensor, the paper describes the design of the sending and receiving coils and realizes the hardware and the software for the sensor. In order to enhance the reliability of the sensor, a support vector machine is used to recognize the fault characters, and the signal flow method is used to locate the faulty parts. The diagnosis information not only can be sent to an upper center control computer to evaluate the reliability of the sensors, but also can realize on-line diagnosis for debugging and the quick detection when the maglev train is off-line. The absolute positioning sensor we study has been used in the actual project.

Mentions: The test situations on the test table for the sensor are shown in Figure 15. The tests include the position mark plate on the medium of the reading area, the position mark plate on the outer side of reading area, the position mark plate on the inner side of reading area and the position mark plate leaning 15 degrees. The four situations described above are all probable to occur in actual application. On the basis of the four situations, the robustness of the sensor can be tested.
