Embodiment 1
[0101] Aiming at the magnetic code marking strategy described above, a method for identifying passive information reading means using a matrix sequence combination information encoding method, for example: magnetic poles "N", "S", and "non-magnetic" respectively represent the value "1", "2", "0", and the absolute positions 001, 011, 111, ... along the track respectively represent the first absolute position, the third absolute position, the seventh absolute position, ..., and The positioning basis of the hardware structure is realized by the magnetic pole characteristics. The positioning of the absolute position of the magnetic pole coding method such as this is applicable to the identification of this method.
[0102] In the magnetic code information identification system in the present embodiment, the vehicle identification code 7 on the vehicle identification device 102 is a permanent magnetic identification code, and the vehicle magnetic code identification sensor 8 is a m...
Embodiment 2
[0114] The present invention has various application schemes according to different collection principles of magnetic code data. In Example 2, another data collection means will be explained in detail. However, it can be understood that the examples are only for further illustrating the present invention, and should not be construed as limiting the content of the present invention.
[0115]The vehicle-mounted identification code 7 of the vehicle-mounted identifier 102 carried by the train in the present embodiment is an electromagnetic winding coil, and the vehicle-mounted magnetic code identification sensor 8 is a current / voltage sensor; the magnetic code row / column separator 3 adopts a permanent magnet rectangular strip, and sensor data monitoring The front-end equipment 6 is a pressure sensor, and the vehicle-mounted identifier 102 sequentially passes through the magnetic pole coding plates 101 along the track to identify and read corresponding positioning information one b...
