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...

Abstract

The invention relates to the technical field of electromagnetic induction identification. The invention discloses a magnetic code information identification system and method, and application. The system comprises a vehicle-mounted recognizer and a magnetic pole coding plate, wherein the vehicle-mounted identifier adopts a vehicle-mounted identification code with preset magnetic sheet polarity, the magnetic pole encoding plate hides required information in a magnetic pole encoding matrix sequence by utilizing magnetic pole characteristics, and the magnetic pole encoding matrix sequence of themagnetic pole encoding plate is read and identified through the interaction of the vehicle-mounted identifier and the magnetic pole encoding plate. The magnetic pole encoding plate performs information encoding storage through magnetic poles and is sequentially laid along a rail, a running vehicle carries the vehicle-mounted magnetic code recognizer to scan, recognize and read positions, road conditions and other information along the way, and the advantages of convenience, high efficiency, high economic value and the like are achieved. In the aspect of the application field, the method can beused for vehicle positioning and speed measurement, road condition information acquisition and other functions of a medium-low speed maglev train, and is also suitable for real-time monitoring of theabsolute position / speed in a conventional rail transit system.

Description

technical field [0001] The invention relates to the technical field of electromagnetic induction, signal identification and processing, and in particular to a magnetic code information identification system and method application. Background technique [0002] The domestic medium and low-speed maglev technology is becoming more and more mature, which has accelerated the pace of its commercialization. The medium and low maglev transportation lines that have been commercialized include the Changsha Maglev Special Line and the Beijing Maglev S1 Line. It is reported that on August 21, 2019, the single-day passenger volume of Beijing Maglev Line S1 reached 41,200 passengers, setting a new high in passenger volume, an increase of 10,000 passengers, or 2.40%, from the highest value in history. This also means that maglev trains are serving the public. At the same time, it is also gradually allowing the masses to accept and recognize this new rail transit system. Under this backgro...
