Description
Technical field
The present invention relates to a kind of track train auxiliary control method based on RFID, belongs to Train Control field.
Background technique
Railway transportation is that China is the most universal and extensive means of transportation, being constantly progressive and develop with Chinese Railway,
The speed of present railway has been getting faster, and rate of traffic flow is higher and higher, then correspondingly, the attention degree of railway security
With regard to higher and higher.The railway accident occurred in recent years be all mostly due to dispatch and artificial fault caused by, so should be into
The reliability of equipment is improved to one step, equipment automatically safety guarantee is improved, reduces the possibility that accident occurs.
Chinese Railway current train operation control system CTCS2, CTCS3 are the positions by track circuit to train
It is positioned, the dependence to track circuit physical separation section can not be got rid of；Even if using movable block or virtual block
The separation quantity of track section can be greatly decreased in the system of mode, but due to the limit by communication speed and system response time
System, the increasingly requirement to meet high rate of traffic flow.Once Dispatch and Command Center is with regard to nothing moreover, failure occurs in track circuit
The position of method determination section train and train is safely and reliably dispatched, not can guarantee safely.
There are also correlative studys to be dedicated to truck traffic system, i.e., leading train is sent to subsequent train comprising train information
Signal is transmitted, the car-mounted device of subsequent train reads the train information of received leading train, according to same with leading train
The current location for the subsequent train for detecting or calculating to sample and train speed, control the travel speed of subsequent train.But such as
The subsequent train of fruit mistakenly receives the leading train before not being an immediately proceeding at but the signal of the leading train in more front, and root
The travel speed of subsequent train is controlled according to the train position of the train, then presence is more than allowed band and approaches originally leading
Train such problems is also greatly limited by environmental factor moreover, this mode is still limited by communication speed, is difficult
Meet high driving density requirements.
In face of the requirement of present high rate of traffic flow and high safety standard, it is contemplated that the various aspects such as cost, construction difficulty are asked
Topic, need it is a kind of can be with Fast Construction, low cost, easy to maintain and can be independently of the Auxiliary Track train except previous system

The leading train information stored in the same RFID electronic label that RFID reader and the second RFID reader are read is mutually superfluous
Remaining, the information that operation control system reads two RFID readers compares, and determines leading train information.
8. a kind of track train auxiliary control method based on RFID according to claim 5, it is characterised in that: described
Train id information is written to RFID electronic label for one RFID reader and train head passes through train when the RFID electronic label
Speed, acceleration and transit time, the second RFID reader train id information and the train tailstock is written to RFID electronic label
By the speed, acceleration and transit time of train when the RFID electronic label, RFID electronic label retains same row automatically
The train speed and acceleration information that vehicle is written later, and retain simultaneously train head's transit time and the train tailstock it is current when
Between；The train passage time includes train head's transit time and train tailstock transit time.
