Automatic identification system for train position type based on RFID technology and application thereof

Abstract

The invention relates to an automatic identification system for train position type based on an RFID technology and application thereof. The system comprises an RFID receiving antenna, ground electronic tags, a system host and an independent display terminal, wherein the ground electronic tags are laid on rails in the vicinity of a main track turnout for identification of train position type; theground electronic tags are divided into seven kinds ranged from A-G according to deploying position type, the tags comprise an A type tag arranged on a straight rail of an up main track and close to astock rail of the turnout, a D type tag arranged on a straight rail of a down main track and close to the stock rail of the turnout, a B type tag arranged on a rail where an up turnout is located andclose to a frog center, an E type tag arranged on a rail where a down turnout is located and close to the frog center, a C type tag arranged on the rail where the up turnout is located and located ata corresponding position of a fouling post, an F type tag arranged on the rail where the down turnout is located and located at the corresponding position of the fouling post, and a G type tag arranged on an entrance and exit line and close to the position of the main track. The system can identify the position type in which a train is currently located well.

Description

technical field [0001] The invention belongs to the technical field of urban rail train tracking, and in particular relates to an RFID technology-based automatic identification system for train position and type and its application. Background technique [0002] When the train auxiliary protection system is in operation, the communication and distance measurement functions between trains can be realized through the radio frequency transceiver antenna, and the head end of the rear car sends an "inquiry signal" through the radio frequency transceiver antenna. After the rear end of the front vehicle receives the "inquiry signal", it can obtain the information and distance of the rear vehicle through decoding and calculation. After the rear end of the front vehicle completes the processing, it sends a "response signal" to the rear vehicle. After receiving the "response signal", the head end of the rear vehicle can obtain the information and distance of the vehicle in front after...

However, this method has the following disadvantages: after the device is started, the driver needs to manually set up, which increases the workload of the driver. If the driver makes a mistake, the system will work abnormally; opposite train

Since the current running direction of the P2 car is "downward", and the current running direction of the P1 car is "upward", according to the above method, the P1 and P2 cars cannot recognize each other. Hidden danger
