Description

Technical Field

[0001] The present invention relates to the field of railway signal control, and in particular to a train mixed operation control method and system. Background Art

[0002] For CTCS-4 train control system lines, trains may be equipped with CTCS-4 train control on-board equipment, or CTCS-2 train control on-board equipment or CTCS-3 train control on-board equipment. Trains of different train control levels may run together to improve the cross-line operation and interconnection of trains of different train control levels.

[0003] The on-board equipment of CTCS-4 train control is based on wireless transmission of train driving permits. The blocking mode is mobile blocking, and the train occupancy check is implemented by the on-board equipment. The on-board equipment of CTCS-2 train control transmits train driving permit information based on track circuits and point transponders. The train occupancy check is implemented by ground equipment, and the blocking mode is quasi-mobile blocking based on fixed block partitions. The on-board equipment of CTCS-3 train control generates train driving permits by the radio block center (RBC) and transmits them to the train via wireless. The train occupancy check is implemented by ground equipment. The blocking mode is the same as that of the CTCS-2 train control system, and adopts quasi-mobile blocking based on fixed block partitions.

[0004] Since the train operation control methods and blocking methods of CTCS-4, CTCS-2 and CTCS-3 train control on-board equipment are different, a single train operation control method may not match the train operation control method with the mixed operation scenario, which may lead to safety risks such as train rear-end collision or affect the train tracking operation efficiency.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] like Figure 1 As shown, it is a flow chart of a train hybrid operation control method provided by an embodiment of the present invention, and the method includes:

[0056] Step 1: Configure the train control onboard equipment;

[0057] Step 2, determine the level of train control onboard equipment for train operation;

[0058] Step 3: Determine the train operation control method of the rear train according to the train control onboard equipment level of the front train and the train control onboard equipment level of the rear train.

[0059] Among them, the rear train is a train behind the front train, and the rear train can also be called the train itself.

[0060] refer to Figure 2 As shown, the train is equipped with at least one of CTCS-4, CTCS-3, and CTCS-2 train control on-board equipment, wherein the CTCS-4 train control on-board equipment has a train integrity check function, wherein train control equipment such as RBC, track circuits and transponders are installed on the ground.

[0061] Among them, trains equipped with CTCS-4 level train control on-board equipment use CTCS-2 level train control on-board equipment as the backup system. When the CTCS-4 level train control on-board equipment fails or the wireless communication with RBC fails, the train control on-board equipment automatically switches to the CTCS-2 level train control on-board equipment for operation; trains equipped with CTCS-3 level train control on-board equipment use CTCS-2 level train control on-board equipment as the backup system. When the CTCS-3 level train control on-board equipment fails or the wireless communication with RBC fails, the train control on-board equipment automatically switches to the CTCS-2 level train control on-board equipment for operation.

[0062] In the above embodiment, by setting CTCS-2 level train control on-board equipment as a backup system in CTCS-4 level train control on-board equipment and CTCS-3 level train control on-board equipment, on the one hand, the overall reliability of the train control system is increased, and on the other hand, the train control system can better adapt to the mixed operation of CTCS-4 level lines.

[0063] Among them, the level of train control onboard equipment that determines train operation specifically includes:

[0064] If the train is equipped with CTCS-4 level train control onboard equipment, and its wireless communication connection with RBC is normal and the train integrity check is intact, the train control onboard equipment level of the train is determined to be CTCS-4 level; otherwise, the train control onboard equipment level of the train is determined to be CTCS-2 level;

[0065] If the train is equipped with CTCS-3 level train control onboard equipment and its wireless communication connection with RBC is normal, the train control onboard equipment level of the train is determined to be CTCS-3 level; otherwise, the train control onboard equipment level of the train is determined to be CTCS-2 level;

[0066] If the train is equipped with CTCS-2 level train control on-board equipment and it has no communication connection with RBC, then the level of the train control on-board equipment used in the train operation is determined to be CTCS-2 level.

[0067] The present invention is based on the characteristics that CTCS-4 level train control on-board equipment wirelessly transmits train driving permits, and CTCS-3 level train control on-board equipment generates train driving permits by a radio block center (RBC). In the case that a train is equipped with multiple train control on-board equipment, the level of the train control on-board equipment of the train operation is judged by detecting the wireless communication connection between the train control on-board equipment and the RBC. Based on this method, the level of the train control on-board equipment of the front train and the rear train can be quickly detected, providing reference data for determining the train operation control method of the rear train.

[0068] Optionally, if there is a track section ahead and it is not occupied normally, it is equivalent to that there is a train ahead and it is running as a CTCS-2 level train control on-board equipment, that is, it is determined that the train ahead is a CTCS-2 level train control on-board equipment.

[0069] See also Figure 3-5 As shown, step 3 specifically includes:

[0070] If the following train is a train running CTCS-2 level train control equipment:

[0071] The CTCS-2 train control onboard equipment of the rear train transmits the train driving permission information based on the track circuit and point balise, and provides the idle track section information ahead to the rear train through the track circuit coding. The driving permission terminal of the rear train is the entrance of the block section where the front train is located. The rear train adopts the quasi-mobile block mode based on the fixed block section for tracking operation. Based on the track circuit and point balise transmission, the corresponding train control onboard equipment adopts the target-distance mode curve to monitor the safe operation of the train.

[0072] If the following train is a train running CTCS-3 level train control onboard equipment:

[0073] The CTCS-3 train control onboard equipment of the rear train obtains the block section status information of the section through RBC and generates a driving permit, and sends the driving permit to the rear train through wireless communication. The driving permit terminal of the rear train is the entrance of the block section where the front train is located. The rear train adopts the quasi-mobile block tracking mode based on the fixed block section. Based on wireless communication transmission, the corresponding train control onboard equipment adopts the target-distance mode curve to monitor the safe operation of the train;

[0074] If the following train is a train running CTCS-4 level train control onboard equipment:

[0075] If the train control onboard equipment level of the front train is CTCS-2 or CTCS-3, the CTCS-4 train control onboard equipment of the rear train obtains the track section status information based on RBC and generates a driving permit, and sends the driving permit to the rear train through wireless communication. The driving permit terminal of the rear train is the entrance of the track section where the front train is located. The rear train adopts the quasi-mobile block mode based on the fixed track section for tracking operation. Based on wireless communication transmission, the corresponding train control onboard equipment adopts the target-distance mode curve to monitor the safe operation of the train;

[0076] If the train control on-board equipment level of the front train is CTCS-4, the CTCS-4 on-board train control equipment of the rear train obtains the train position of the front train based on RBC and generates a driving permit, and sends the driving permit to the rear train through wireless communication. The driving permit terminal of the rear train is the tail of the front train. The rear train adopts moving block tracking mode. Based on wireless communication transmission, the corresponding train control on-board equipment adopts the target-distance mode curve to monitor the safe operation of the train.

[0077] In addition, when the on-board equipment of the train control in front fails or fails to communicate with the RBC, the level of the on-board equipment of the train control in front is further redetermined according to step 2, and based on the redetermined level of the on-board equipment of the train control in front, the train operation control method of this vehicle is redetermined according to step 3.

[0078] Among them, if the train control on-board equipment of the train ahead is configured with CTCS-3 level train control on-board equipment, when the CTCS-3 level train control on-board equipment fails or fails to communicate with the RBC, the system will automatically switch to the CTCS-2 level backup system.

[0079] If the train control on-board equipment of the train ahead is configured with CTCS-4 level train control on-board equipment, when the CTCS-4 level train control on-board equipment (including train integrity check) fails or fails to communicate with the RBC, the system will automatically switch to the CTCS-2 level backup system.

[0080] The above method is compatible with the operation control of trains equipped with CTCS-2 and CTCS-3 train control. On this basis, trains equipped with CTCS-4 train control select the corresponding driving permission terminal and blocking mode according to the train control level of the onboard equipment of the preceding train, thereby further improving the train tracking efficiency while ensuring the safe operation of the train.

[0081] As another embodiment of the present invention, a train hybrid operation control system is also provided, the system comprising a configuration module, a train control system level judgment module and a train operation control module;

[0082] The configuration module is used to configure the train control onboard equipment;

[0084] The train operation control module is used to determine the train operation control method of the rear train according to the train control level of the on-board equipment of the front train and the train control level of the on-board equipment of the rear train.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
