Rail transit plays an important role in strengthening urban radiant force of centers and guiding urban industrial economy and healthy development of homeland space.

For important transportation hubs, the operation requirements are relatively complex, and the CTCS2+ATO train control system and the CBTC system exist. In order to meet the requirement of networked operation, engineering application research of compatibility of CTCS2+ATO and CBTC double-vehicle train control system is required to be promoted. The double-vehicle train control system is compatible with a train with two sets of vehicle systems, namely CTCS2+ ATO and CBTC, which is required to run on two different systems of lines, and obviously one method is to install two different vehicle-mounted devices, so that a driver can control the running of the train under different lines independently by manually closing and starting the vehicle-mounted devices at a specific place. However, in the method, on one hand, the equipment is redundant, and the train needs enough space for installation, and on the other hand, the dynamic seamless switching between the vehicle-mounted equipment is realized, so that the operation efficiency is improved. There is currently no suitable solution.

However, the method does not consider the problem of equipment redundancy and specific switching modes under different switching scenes.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

The embodiment provides a method for running CBTC lines on a CTCS2+ATO vehicle-mounted overline, which is suitable for a train provided with a CTCS2+ATO system and a CBTC two-set vehicle-mounted system at the same time.

As shown in FIG. 1, the CTCS2+ATO vehicle-mounted system and the CBTC vehicle-mounted system share peripheral DMI, speed sensor, radar, BTM, antenna and the like, so that the equipment cost is reduced. The CTCS2+ATO and the CBTC vehicle-mounted cabinet are independently arranged, BTMs, speed sensors, radars, antennas and other devices are respectively connected into the two sets of vehicle-mounted cabinets in a signal power division mode, and TCR antennas of the two sets of vehicle-mounted equipment which cannot be shared, such as CTS2+ATO, are connected and installed in an existing mode.

Two sets of vehicle originally have two personal computer display Devices (DMIs) (one for main use and one for standby use), but a driver cab has a difficult enough space to install 4 DMI devices simultaneously. In order to save space and reduce the operation objects of a driver, a DMI screen combination mode can be adopted. A DMI is used for simultaneously running the display programs of CBTC and CTCS2 plus ATO, a driver can manually select a required program to run at the front end through the interface of the DMI, and the other set of program to run at the background to realize the manual switching of the interface.

In addition, the CBTC and the CTCS2+ATO vehicle-mounted systems originally have independent interfaces with the train, such as a traction braking system, but in order to ensure that only one set of vehicle-mounted systems controls the train at the same time, a train interface switching unit is arranged by using relay equipment. When the CBTC vehicle-mounted system controls the vehicle, the relay outputs low level, the train interface switching unit keeps the connection of the CBTC vehicle-mounted system, and the connection of the CTCS2+ATO vehicle-mounted system and a train is cut off; when the CTCS2+ATO vehicle-mounted system is in control, the relay outputs high level, the interface switching unit cuts off the connection between the CBTC vehicle-mounted system and the train, and the connection between the CTCS+ATO vehicle-mounted system is reserved.

After the CTCS2+ATO vehicle-mounted system and the CBTC vehicle-mounted system are electrified, the CTCS2+ATO vehicle-mounted system is used as main equipment to have the right of controlling the train preferentially through the interface switching unit. Before formal online operation, a driver needs to manually switch screens to finish the startup registration process of two sets of vehicle-mounted systems. For example, the driver starts the CBTC on-board system before starting the ctctcs2+ato on-board system, and starts the ctcs2+ato on-board system after the CBTC on-board system enters the operation mode. At this time, the CTCS2+ATO on-board system receives the control right, and the CBTC system enters a mode of controlling the vehicle by the CTCS 2+ATO. The CTCS2+ATO vehicle-mounted system continues the starting-up registration process, and after the default registration is finished, the CTCS2+ATO system enters a partial mode, so that a driver can run a train in the partial mode. If the driver wants to control the train using the CBTC on-board system, he can also manually operate on the DMI so that the ctcs2+ato on-board system exchanges control. At this time, the CTCS2+ATO vehicle-mounted system defaults to a CBTC control mode, and whether the CTCS2+ATO vehicle-mounted fails or not does not influence the CBTC vehicle-mounted operation.

As shown in fig. 2, when the CTCS2+ato vehicle-mounted system controls the train to run to the common management area of the two system lines, the vehicle-mounted system still runs according to the driving permission information provided by the CTCS-2 trackside equipment; after the train passes the positioning transponder of the CBTC, the CBTC system registers with the ZC of the CBTC trackside equipment, and the ZC starts to calculate the movement authorization; the CTCS2+ATO vehicle-mounted system predicts line mode conversion at a line mode conversion predicting point, and obtains a confirmation result of an operator (driver), if the operator confirms to perform line mode conversion, when the CTCS2+ATO vehicle-mounted system controls a train to run to a mode conversion point, the system is automatically switched to a CBTC vehicle-mounted system, and meanwhile, a DMI interface is automatically switched to CBTC display; if the operator does not confirm, the CTCS2+ATO vehicle-mounted system controls the train to stop at the end of the line.

When the CBTC vehicle-mounted system controls the train to run to a common management area of two standard lines, the vehicle-mounted system runs according to the movement authorization provided by CBTC trackside equipment ZC, the CTCS2+ATO vehicle-mounted system acquires line data from a transponder, acquires driving license information from a track circuit, and starts to calculate an operation curve in real time; when the CBTC vehicle-mounted system controls the train to run to a line system switching point, the train is automatically switched to the CTCS2+ATO vehicle-mounted system, and meanwhile, the DMI interface is switched to CTCS2+ATO for display, and the train runs according to the running permission information provided by the CTCS-2 trackside equipment.

The CTCS2+ATO vehicle-mounted system and the CBTC vehicle-mounted system communicate state information through 422 serial ports. That is, the ctcs2+ato vehicle-mounted system can acquire status information of whether the CBTC vehicle-mounted system is faulty or not, and the CBTC vehicle-mounted system can also acquire status information of whether the ctcs2+ato vehicle-mounted system is faulty or not.

When the CTCS2+ATO vehicle-mounted system works and the state information of the CBTC vehicle-mounted system is obtained to indicate that the CBTC vehicle-mounted system fails, the CTCS2+ATO vehicle-mounted system calculates a braking curve by taking the tail end of a common-management-area line as an end point, and controls a train to stop before entering the CBTC line, so that the train is ensured not to be switched to the CBTC vehicle-mounted system in the common-management area.

Similarly, when the CBTC vehicle-mounted system is working and the state information of the CTCS2+ATO vehicle-mounted system is obtained to indicate that the CTCS2+ATO vehicle-mounted system fails, the CBTC vehicle-mounted system calculates a braking curve by taking the tail end of a common-control zone line as an end point, and controls a train to stop before entering the CTCS2+ATO line, so that the train is ensured not to be switched to the CTCS2+ATO vehicle-mounted system in the common-control zone.
