Description

Device and method for identifying train consist of connected trains

Technical Field

The invention belongs to the technical field of rail transit, and particularly relates to a rail transit signal system.

Background

The prior art scheme obtains the information of the train consist of the linked trains by any one of the following modes:

1) A vehicle link circuit;

2) Communication among all the marshalling unit column workshops after connection and hanging;

3) Feeding back train grouping information of the linked trains to the linked trains through ZCs;

the signal system identifies and judges the grouping information of the train after the train is connected according to any mode, such as 3+3 grouping or 3+6 grouping.

The prior art has the following problems:

1) When train formation information of a train is obtained through a train coupling circuit, when more than three marshalling units are coupled, the train circuit is complex, the number of the coupling train marshalling conditions after being arranged and combined according to the train formation information and the train type information is large, if the coupling train marshalling conditions are all identified through relay interface information of a vehicle, the number of required relays is large, and the number of the relays which can be supported is limited according to the limit of installation space in the vehicle;

2) The precondition of the mode of acquiring the group information of the linked train through the communication between the group unit trains after the linking is as follows: communication between vehicle-mounted CCs of each train workshop can be established after the train is connected;

3) The precondition of feeding back the group information of the linked trains to the linked trains through ZC is that: the vehicle-mounted CC of each train establishes communication with the ZC and reports the train grouping information and the type information to the ZC;

however, in the actual line use process, too many relays cannot be provided by the vehicle circuit for the connection function, and after the train is connected, communication between the vehicle-mounted CCs of each train workshop cannot be established, and communication between the vehicle-mounted CCs and the ZCs is not guaranteed before the connection is performed, and the ZCs are not provided with equipment for each line.

Therefore, when the grouping information of the train after the train is connected cannot be obtained through the three modes, the signal system cannot call train control and protection data corresponding to the train after the train is connected, and a complete connecting function cannot be realized.

In order to solve the technical problems, the invention adopts the following technical scheme:

on one hand, the invention provides a train group identification device for a train to be hung, wherein at least two trains are hung, the trains are provided with a vehicle-mounted CC and a train-hanging detection module, the train-hanging detection module is used for detecting whether the train-hanging is successful or not, feeding back information of the state of the train-hanging to a signal system, and an RFID electronic tag and an RFID card reader are arranged on a train-hanging connection surface of the train to be hung, and the RFID electronic tag stores vehicle parameters and train group information;

when at least two trains are connected, the RFID card reader on any train is used for reading RFID electronic tag information on the other train;

the vehicle-mounted CC acquires the linking state information from the vehicle, judges whether linking grouping combination information after linking is a defined allowed linking grouping combination type according to the train parameter information of the vehicle and the parameter information of the linked train acquired from the RFID card reader when linking is successful, and automatically replaces corresponding linking train grouping combination parameters when the judgment result is yes.

Preferably, the vehicle parameters include a train PVID number, train consist information, train type information, and train length information.

In another aspect, a method for identifying a train consist is provided, and the train consist identification device is used for identifying the train consist, including the following steps:

step two: the vehicle detects that the two vehicles are successfully connected, a connection success signal is fed back to the signal system, and otherwise, an unconnected signal is fed back;

step three: the vehicle-mounted CC of each train respectively acquires parameter information of the connected train through the RFID card reader, and if the vehicle-mounted CC acquires the connected state information from the train as not connected, the vehicle-mounted CC keeps the current loaded parameters unchanged; when the vehicle-mounted CC acquires the information of the coupling state from the vehicle as coupling success, the vehicle-mounted CC judges whether coupling grouping combination information after coupling is a coupling grouping combination type which is defined in a system according to the self train parameter information and the parameter information of the coupled train acquired from the RFID card reader;

step four: if the judgment result of the step three is yes, the vehicle-mounted CC automatically changes the corresponding train grouping combination parameters; if not, alarming through ATS and TOD, prompting central dispatch and driver' abnormal connection and prohibition of train operation;

step five: after the vehicle-mounted CC is automatically replaced by the corresponding train grouping parameter, the vehicle-mounted CC performs train operation safety protection and train overspeed protection according to the newly loaded train grouping parameter.

2. The method is free from limiting the driving mode of the continuous train, from limiting the communication state between each marshalling unit train and ZC in the continuous train, from limiting whether the communication network between each marshalling unit train in the continuous train is open or not, and has wider application range.

3. The vehicle only needs to provide a status signal of whether the connection is successful or not, such as a connection success signal and a connection non-connection signal, and compared with the prior art, the interface design and the relay number between a signal system and the vehicle about connection are reduced.

The connecting surface of the train is provided with an RFID electronic tag and an RFID card reader, and the RFID electronic tag stores vehicle parameters and train grouping information (see the description of the front 2). When at least two trains are connected, the RFID card reader on any train is used for reading RFID electronic tag information on the other train. By embedding the RFID electronic tag and the RFID card reader on the connecting surface, the method is used as a bridge for each marshalling unit train in the connecting train to acquire marshalling information and train type information of other marshalling units, and interference and influence on the existing vehicle-mounted CC are effectively avoided.

The vehicle-mounted CC acquires the linking state information from the vehicle, judges whether the linked grouping combination information after linking is a defined allowed linked grouping combination type (see the description of the front 4) according to the train parameter information of the vehicle and the parameter information of the linked train acquired from the RFID card reader when linking is successful, and automatically replaces the corresponding linked train grouping combination parameter when the judging result is yes.

Example two

In combination with fig. 1, a car and a car B are connected, and the car a uses the connected train grouping recognition device according to the first embodiment to recognize the connected train grouping in front of the running direction.

The whole process of the train group identification method for the train is as follows:

step one: and the train CC controls the train B to be connected with the train A, and the RFID reader on the connecting surface of the two trains reads the RFID electronic tag information on the other connecting surface.

Step two: the vehicle detects that the two vehicles are successfully connected, a connection success signal is fed back to the signal system, and otherwise, an unconnected signal is fed back. Because the vehicle only needs to provide the status signal of whether the vehicle is connected, compared with the prior art, the interface design and the relay number between the signal system and the vehicle about the connection are reduced.

Step three: and the vehicle-mounted CC of the B vehicle and the vehicle-mounted CC of the A vehicle respectively acquire parameter information of the connected train through the RFID card reader, and if the vehicle-mounted CC acquires that the connected state information is not connected from the vehicle, the vehicle-mounted CC keeps the current loaded parameters unchanged. When the vehicle-mounted CC acquires the information of the linking state from the vehicle as linking success, the vehicle-mounted CC judges whether the linked grouping combination information after linking is the allowed linked grouping combination type defined in the system according to the self train parameter information and the parameter information of the linked train acquired from the RFID card reader. If yes, the vehicle-mounted CC automatically changes corresponding parameters of the linked train grouping combination (including grouping type and train type); if not, alarming and prompting the central dispatching and a driver to be abnormal in connection and prohibiting the train from running through the ATS and the TOD.

Step four: after the vehicle-mounted CC is automatically replaced by the corresponding train grouping parameter, the vehicle-mounted CC performs train operation safety protection and train overspeed protection according to the newly loaded train grouping parameter.

The invention does not limit the driving mode of the continuous train, the communication state between each marshalling unit train and ZC in the continuous train, whether the communication network between each marshalling unit train in the continuous train is open or not, and the application range is wider.
