Description

Technical Field

[0001] The present invention belongs to the technical field of rail transit, and particularly relates to a rail transit signal system. Background Art

[0002] The prior art solutions obtain the formation information of coupled trains through any of the following methods:

[0003] 1) Vehicle coupling circuit;

[0004] 2) Communication between each formation unit train after coupling;

[0005] 3) Feeding back the formation information of coupled trains to the coupled trains by ZC;

[0006] The signal system identifies and determines the formation information of the coupled trains according to any of the above methods, such as 3+3 formation or 3+6 formation, etc.

[0007] The prior art has the following problems:

[0008] 1) When obtaining the formation information of coupled trains through the vehicle coupling circuit, when there are three or more formation unit trains coupled, the vehicle circuit will be very complex. There will be many formation situations of coupled trains after permutation and combination according to the train formation information and train type information. If all are identified through the relay interface information of the vehicle, a large number of relays will be required. Moreover, due to the limitation of the installation space inside the vehicle, the number of relays that can be supported is limited;

[0009] 2) The prerequisite for obtaining the formation information of coupled trains through the communication between each formation unit train after coupling is that the on-vehicle CCs between the trains can establish communication after the trains are coupled;

[0010] 3) The prerequisite for feeding back the formation information of coupled trains to the coupled trains by ZC is that the on-vehicle CCs of each train have established communication with ZC and reported the train formation information and type information to ZC;

[0011] However, in the actual line operation process, for the coupling function, the vehicle circuit cannot provide too many relays. Moreover, after the trains are coupled, the on-vehicle CCs between the trains may not be able to establish communication. It is not guaranteed that each train has established communication with ZC before coupling, and not every line has the ZC device.

[0012] Therefore, when the formation information of the coupled trains cannot be obtained through the above three methods, the signal system cannot call the train control and protection data corresponding to the coupled formation trains, and the complete coupling function cannot be realized. Summary of the Invention

[0013] Aiming at the problems existing in the prior art in obtaining the formation information of coupled trains, the technical problem to be solved by the present invention is to provide a coupled train formation recognition device and method, which can accurately and reliably obtain the formation information of the trains after coupling, so that the signal system can call the train control and protection data corresponding to the coupled trains to realize the complete coupling function.

[0014] To solve the above technical problems, the present invention adopts the following technical solutions:

[0015] On the one hand, a coupled train formation recognition device is provided. At least two trains are coupled. Each train is equipped with an on-vehicle CC and a coupling detection module. The coupling detection module is used to detect whether the coupling is successful and feedback the coupling status information to the signal system. An RFID electronic tag and an RFID reader are installed on the coupling connection surface of the coupled trains. The RFID electronic tag stores vehicle parameters and train formation information.

[0016] When at least two trains are coupled, the RFID reader on any one of the trains is used to read the RFID electronic tag information on another train.

[0017] The on-vehicle CC obtains the coupling status information from the vehicle. When the coupling is successful, it judges whether the coupled formation combination information after coupling is a defined allowable coupled formation combination type according to its own train parameter information and the parameter information of the coupled train obtained from the RFID reader, and automatically replaces the corresponding coupled train formation combination parameters when the judgment result is yes.

[0018] Preferably, the vehicle parameters include train PVID number, train formation information, train type information, and train length information.

[0019] On the other hand, a coupled train formation recognition method is provided. The coupled train formation recognition device described above is used for coupled train formation recognition, including the following steps:

[0020] Step 1: At least two trains are coupled, and the RFID reader on each train reads the RFID electronic tag information on another train.

[0021] Step 2: The vehicle detects that the two trains are successfully coupled and feeds back a coupling success signal to the signal system, otherwise feeds back an uncoupled signal.

[0022] Step 3: The on-vehicle CC of each train obtains the parameter information of the coupled train through the RFID card reader respectively. If the on-vehicle CC obtains the uncoupled status information from the vehicle, the on-vehicle CC keeps the currently loaded parameters unchanged; when the on-vehicle CC obtains the successfully coupled status information from the vehicle, the on-vehicle CC determines whether the coupled formation combination information after coupling is the allowed coupled formation combination type defined in the system according to its own train parameter information and the parameter information of the coupled train obtained from the RFID card reader.

[0023] Step 4: If the judgment result in Step 3 is yes, the on-vehicle CC automatically replaces the corresponding coupled train formation combination parameters; if not, it alarms through the ATS and TOD, and prompts the central dispatcher and the driver of "abnormal coupling", and prohibits the train from running.

[0024] Step 5: After the on-vehicle CC automatically replaces the corresponding coupled train formation parameters, the on-vehicle CC performs train operation safety protection and train overspeed protection according to the newly loaded coupled train formation parameters.

[0025] The technical solution adopted by the present invention realizes the identification of the coupled train formation information and train type information by setting RFID electronic tags and RFID card readers on the coupling connection surface.

[0026] Therefore, it has the following beneficial effects:

[0027] 1. By embedding RFID electronic tags and RFID card readers on the coupling connection surface, as a bridge for each formation unit train in the coupled train to obtain the formation information and train type information of other formation unit trains, it effectively avoids the possible interference and influence on the existing on-vehicle CC.

[0028] 2. It does not limit the driving mode of the coupled train, does not limit the communication status between each formation unit train in the coupled train and the ZC, and does not limit whether the communication network between each formation unit train in the coupled train is connected, so the application range is wider.

[0029] 3. The vehicle only needs to provide the status signals of whether it is coupled or not, such as the successfully coupled and uncoupled signals. Compared with the existing technology, it reduces the interface design and the number of relays between the signal system and the vehicle regarding coupling.

[0030] 4. It does not limit the coupling area or location. Anywhere can obtain the coupled train formation information through this method, and call the corresponding train parameters according to the obtained information for train operation safety protection, with more obvious advantages.

[0034] The technical solutions of the embodiments of the present invention will be explained and described below in conjunction with the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0035] Pre - explanation 1: An RFID electronic tag and an RFID reader have been installed on the coupler connection surface after the trains are coupled.

[0036] Pre - explanation 2: When the vehicle leaves the factory, the relevant vehicle parameters required by the signal system (including train PVID number, train formation information, train type information, train length information) have been stored in the RFID electronic tag.

[0037] Pre - explanation 3: The vehicle provides the coupler status information to the signal system, including the successful coupling signal and the non - coupling signal.

[0038] Pre - explanation 4: The allowed types of coupled formations have been defined in the system.

[0039] CC: On - vehicle controller

[0040] ATS: Train Automatic Supervision system

[0041] TOD: On - vehicle signal display screen

[0042] Embodiment 1

[0043] Combined with Figure 1 , a coupled train formation identification device, at least two trains are coupled. The train is provided with an on - vehicle CC and a coupling detection module. The coupling detection module is used to detect whether the coupling is successful and feedback the coupling status information to the signal system.

[0044] Among them, an RFID electronic tag and an RFID card reader are installed on the coupling connection surface of the coupled train. The RFID electronic tag stores vehicle parameters and train formation information (see the description in the preamble 2). When at least two trains are coupled, the RFID card reader on any one of the trains is used to read the RFID electronic tag information on the other train. By embedding the RFID electronic tag and the RFID card reader on the coupling connection surface, as a bridge for each formation unit train in the coupled train to obtain the formation information and train type information of other formation unit trains, it effectively avoids possible interference and influence on the existing on-vehicle CC.

[0045] The on-vehicle CC obtains the coupling state information from the vehicle. When the coupling is successful, according to its own train parameter information and the parameter information of the coupled train obtained from the RFID card reader, it judges whether the coupled formation combination information after coupling is a defined allowable coupled formation combination type (see the description in the preamble 4), and automatically replaces the corresponding coupled train formation combination parameters when the judgment result is yes.

[0046] It can be understood that the coupling detection module belongs to the prior art. Therefore, the specific method for the vehicle to detect whether the two trains are successfully coupled can refer to the prior art.

[0047] Embodiment 2

[0048] Combined with Figure 1 , Train A and Train B are coupled. Train A is in the front in the running direction, and a coupled train formation identification device described in Embodiment 1 is used for coupled train formation identification.

[0049] The whole process of a method for identifying the formation of a coupled train is as follows:

[0050] Step 1: The CC of Train B controls Train B and Train A to be coupled, and the RFID card reader on the coupling connection surface of the two trains reads the RFID electronic tag information on the other coupling connection surface.

[0051] Step 2: The vehicle detects that the two trains are successfully coupled and feeds back a coupling success signal to the signal system, otherwise it feeds back an uncoupled signal. Since the vehicle only needs to provide the coupling status signal, compared with the prior art, it reduces the interface design and the number of relays between the signal system and the vehicle regarding coupling.

[0052] Step 3: The on-vehicle CCs of Train B and Train A respectively obtain the parameter information of the coupled train through the RFID card readers. If the on-vehicle CC obtains the coupling status information as "uncoupled" from the vehicle, the on-vehicle CC keeps the currently loaded parameters unchanged. When the on-vehicle CC obtains the coupling status information as "coupled successfully" from the vehicle, the on-vehicle CC determines whether the coupled formation combination information after coupling is the allowed coupled formation combination type defined in the system according to its own train parameter information and the parameter information of the coupled train obtained from the RFID card reader. If so, the on-vehicle CC automatically replaces the corresponding coupled train formation combination (including formation type and train type) parameters; if not, it alarms through the ATS and TOD and prompts the central dispatcher and the driver of "abnormal coupling", and prohibits the train from running.

[0053] Step 4: After the on-vehicle CC automatically replaces the corresponding coupled train formation parameters, the on-vehicle CC performs train operation safety protection and train overspeed protection according to the newly loaded coupled train formation parameters.

[0054] The present invention does not limit the driving mode of the coupled train, does not limit the communication status between each formation unit train in the coupled train and the ZC, and does not limit whether the communication network between each formation unit train in the coupled train is connected, so the application range is wider.

[0055] The present invention does not limit the coupling area or the coupling location. The formation information of the coupled train can be obtained by this method anywhere, and the corresponding train parameters can be called according to the obtained information for train operation safety protection, and the advantages are more obvious.

[0056] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
