Abstract

In this train operation control method, once any device in the system fails, the train will stop, lacking redundancy; Second, there is a track occupancy detection device installed on the trackside of the section, and the train operation control system adopts a single system, represented by the existing CTCS-0 four-display automatic block system. In this train operation control method, once any device in the system fails, the train will stop, lacking redundancy; Third, there is a track occupancy detection device installed on the trackside of the section, and the train control system adopts a dual system, such as the existing high-speed rail CTCS-3 (Chinese Train Control System 3, Chinese Train Control System Third Generation) system, which consists of CTCS-3 and CTCS-2 (Chinese Train Control System 2. China Train Control System (second generation) consists of two systems with high redundancy. However, if a section track circuit fault occurs, the redundancy of the CTCS-3 and CTCS-2 dual systems will be lost, and the train will be braked to a stop until the section track circuit fault is repaired. The train will then be allowed to continue running.
[0003] Therefore, there is an urgent need for a train operation control method to improve the redundancy and stability of the train control system. Summary of the Invention

[0025] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0027] Example 1
[0028] Figure 1a This is a system architecture diagram of a hybrid train control system provided in Example 1 of the present invention, such as Figure 1aAs shown, the hybrid train control system includes on-board equipment, ground equipment and ground wireless communication system; the on-board equipment may include EOT (End of Train Device) and ATP / ATO (Automatic Train Protection / Automatic Train Operation) units; the ground equipment may include transponders and track circuits, TSRS (Train Stop Recognition System), RBC (Radio Block Center), TIS (Train Information System), TCC (Train Communication and Control system), CTC (Centralized Traffic Control system) and CTC station extensions.
[0029] EOF can be used to collect wind pressure information at the rear of the train and securely transmit it to the ATP at the head of the train for train integrity checks. ATP can monitor train speed curves based on driving permit information provided by ground equipment, and has both CTCS-N and CTCS-2 level capabilities. ATO can be used to implement automatic train driving within ATP curves. TIS can be used to implement station interlocking, controlling trackside equipment such as station signals and switches through a target controller. RBC can calculate MA (Movement Authority) based on station route information, section direction, and train position within the jurisdiction provided by the TIS, and send driving permits, line parameters, and temporary speed limit commands to the ATP via train-to-ground wireless communication. TSRS can be used to manage temporary speed limits, electronic maps, and operation plan data within the section. CTC can display train, line, and station operation status information and provide train operation-related operations. CTC station extensions can refer to station communication equipment or telephone systems within the CTC. It should be noted that the above-mentioned equipment or systems have their own basic functions.
[0030] It should be noted that this hybrid train control system integrates the first train control system and the second train control system. For example, RBC is required for the second train control system, and the operation of the first train control system does not need to be based on RBC. The second train control system can use RBC to send wireless MA to the ATP via the ground wireless communication system, and the first train control system can use track circuit MA to send coded information to the ATP. Optionally, the first train control system can be set to CTCS-2, and the second train control system can be set to CTCS-N (Chinese Train Control System N, the latest version of the Chinese Train Control System).
[0031] Optionally, the hybrid train control system also includes LKJ (Locomotive Keying and Jumping), which integrates the CTCS-0 system.
[0032] The hybrid train control system architecture integrates relevant equipment from both the CTCS-2 and CTCS-N systems. If the signaling trackside equipment (track circuit) fails, the train can switch to the CTCS-N system. If the communication trackside equipment fails (for example, if train-to-ground wireless communication is interrupted), the train can switch to the CTCS-2 system. If both the signaling trackside equipment and the communication trackside equipment fail simultaneously, the train can switch to the backup CTCS-0 system. This provides extremely high redundancy and enhances the resilience of the system's stable operation.
[0033] Figure 1b A flow chart of a switchable train operation control method is provided for the first embodiment of the present invention. This embodiment is applicable to the case where the train operation is controlled after the train starts. The method is applied to a hybrid train control system including a first train control system and a second train control system. The method can be executed by a switchable train operation control device. The switchable train operation control device can be implemented in the form of hardware and / or software. The switchable train operation control device can be configured in various general-purpose computing devices. Figure 1b As shown, the method includes:
[0034] S110 . Based on the track circuit physical sections, set a corresponding track circuit virtual section for each track circuit physical section.
[0035] Among them, the track circuit physical section can refer to the track area where the track circuit is set up, and the track circuit physical section has a corresponding physical device (track circuit). The track circuit virtual section can refer to the virtual section established for the track area where the track circuit is set up. In other words, the same track area can have track circuit physical sections and track circuit virtual sections, which are used to indicate the same track area (section), and only the track circuit physical section has a corresponding physical device, and the track circuit virtual section does not have a corresponding physical device.
[0036] It should be noted that the first train control system can control the train operation based on the physical section of the track circuit, and the second train control system can control the train operation based on the virtual section of the track circuit, decoupling to form different safety control logics under the same track circuit conditions.
[0037] In an embodiment of the present invention, a track circuit virtual section may be pre-set corresponding to each track circuit physical section, so that when a track circuit fault occurs, the second train control system may be used to control the train operation based on the track circuit virtual section.
[0038] Optionally, when the usage status of the track circuit physical section is idle, the usage status of the track circuit virtual section corresponding to the track circuit physical section is idle; when the usage status of the track circuit physical section is occupied, if there is no communication train position report in the track circuit physical section and the safety logic check passes, the usage status of the track circuit virtual section corresponding to the track circuit physical section is updated to idle.
[0039] The usage status can be used to indicate whether a physical track circuit section or a virtual track circuit section allows trains to pass through. The idle status can indicate whether a physical track circuit section or a virtual track circuit section allows trains to pass through. The occupied status can indicate whether a physical track circuit section or a virtual track circuit section does not allow trains to pass through. Optionally, the occupied status can also be used to indicate that a physical track circuit section is a safety troubleshooting section (a section where a fault has occurred).
[0040] Optionally, in an embodiment of the present invention, when the usage status of the track circuit physical section is occupied, it is necessary to first determine whether there is a communication train in the track circuit physical section. Since the train needs to consider the entire vehicle length range from the head to the tail of the train, the specific judgment process can determine whether there is a communication train in the track circuit physical section based on the train position report of the communication train, and in the case of the existence of a communication train, the train integrity is detected based on ATP and EOT, and the RBC can determine whether the communication train has cleared the track circuit physical section.
[0041] Among them, the safety logic check can be used to determine whether there is a non-communication train in the track circuit physical section. The safety logic check may include manually sending a section idle instruction or dispatching the first communication train to clean the track circuit physical section with an occupied status at a preset cleaning speed; the first communication train may refer to the communication train that is closest to the track circuit physical section with an occupied status and has not entered the track circuit physical section. It should be noted that non-communication trains cannot send train position reports to determine their positions, so it is necessary to clean the track circuit physical section with an occupied status. Optionally, the preset cleaning speed can be adaptively set according to those skilled in the art.
[0042] S120. Based on the fault type of the hybrid train control system, determine a target train control system in the first train control system and the second train control system, and control the train to run within the track circuit entity section.
[0043] The fault types may include signal wayside equipment faults and communication wayside equipment faults. It should be noted that a wayside equipment fault may refer to a track circuit fault, and a communication wayside equipment fault may refer to a train-to-ground wireless communication fault. The target train control system may refer to the train control system that controls train operation after a hybrid train control system fault occurs.
[0044] Specifically, during the operation of the train, the target train control system can be flexibly determined in the first train control system and the second train control system according to the type of fault occurring in the hybrid train control system to control the train to operate in the track section to which the track circuit physical section belongs.
[0045] The technical solution of the embodiment of the present invention sets a one-to-one corresponding track circuit virtual section for the track circuit physical section, so that the first train control system controls the train operation based on the track circuit physical section, and the second train control system controls the train operation based on the track circuit virtual section. Based on the different types of faults in the hybrid train control system, different target train control systems are determined to control the train operation, so that the first train control system and the second train control system are relatively independent, further improving the redundancy and stability of the train control system.
[0046] Example 2
[0047] Figure 2This is a flow chart of a switchable train operation control method provided in the second embodiment of the present invention. This embodiment further refines the above embodiment and provides specific steps for determining the target train control system in the first train control system and the second train control system based on the fault type of the hybrid train control system, and controlling the train to operate in the physical section of the track circuit. It should be noted that for the parts not described in detail in the embodiment of the present invention, please refer to the relevant descriptions of other embodiments, which will not be repeated here. Figure 2 As shown, the method includes:
[0048] S210: Based on the track circuit physical sections, set a corresponding track circuit virtual section for each track circuit physical section.
[0049] S220. When a signal wayside equipment failure occurs in the hybrid train control system, determine the second train control system as the target train control system.
[0050] S230. Using the driving permission generated by the target train control system based on the usage status of the track circuit virtual section, control the train to run within the track circuit virtual section.
[0051] S240. When a communication trackside equipment failure occurs in the hybrid train control system, determine the first train control system as the target train control system.
[0052] S250. Using the driving permission generated by the target train control system based on the usage status of the track circuit physical section, control the train to run within the track circuit physical section.
[0053] Optionally, after a signal trackside equipment failure occurs in the hybrid train control system, the method further includes: updating the usage status of the track circuit virtual section corresponding to the faulty track circuit physical section to an occupied status through the radio block center.
[0054] In an embodiment of the present invention, if a signaling wayside device failure occurs in a hybrid train control system, the use status of the physical track circuit section where the signaling wayside device failure occurs can be updated to an occupied state via the radio block center. The use status of the physical track circuit section prohibits train passage. In this case, the second train control system in the hybrid train control system can be switched to be the target train control system. The train can be controlled to operate within the track section to which the virtual track section belongs based on the driving permit generated based on the driving permit of the virtual track section. If a communication wayside device failure occurs in the hybrid train control system, the hybrid train control system cannot transmit the driving permit to the ATP based on train-to-ground wireless communication. In this case, the first train control system in the hybrid train control system can be switched to be the target train control system. The driving permit generated based on the driving permit of the physical track section can be sent to the ATP via the track circuit to control the train to operate within the track section to which the physical track section belongs.
[0055] Optionally, the target train control system generates a driving permit based on the usage status of the track circuit virtual section to control the train to operate within the track circuit virtual section, including: when the safety logic check of the track circuit physical section where the signal wayside equipment failure occurs is passed, the usage status of the track circuit virtual section corresponding to the track circuit physical section is updated to an idle state; based on the radio block center, a driving permit is generated according to the updated usage status of the track circuit virtual section to control the train to operate within the track section to which the track circuit virtual section belongs, and at the same time, the usage status of the track circuit virtual section is updated to an occupied state; and after the train completes clearance within the track circuit physical section, the usage status of the track circuit virtual section is updated to an idle state.
[0056] Specifically, in the event of a signal wayside equipment failure, that is, when the usage status of a track circuit physical section is occupied, if the track maintenance personnel can promptly confirm that the rails belonging to the track circuit physical section are in good condition, that is, there are no abnormal conditions such as breakage of the rails in the track circuit physical section, a safety logic check can be issued to the track circuit physical section. If the safety logic check passes, the usage status of the track circuit virtual section corresponding to the track circuit physical section is updated to idle through the radio block center. At this time, since the track circuit in the track circuit physical section has not been inspected and repaired, the usage status of the track circuit physical section is occupied, and the update status of the track circuit virtual section corresponding to the track circuit physical section has been updated to idle. Therefore, the radio block center can generate a driving permit based on the usage status of the track circuit virtual section to control the train in the track circuit. When a train runs in the track section to which the virtual section of the track circuit belongs, and when the train runs in the physical section of the track circuit, the usage status of the virtual section of the track circuit is updated from idle to occupied through the radio block center, and after the train completes the clearance in the physical section of the track circuit, the usage status of the virtual section of the track circuit is updated to idle. If the track maintenance personnel cannot confirm in time whether the rails belonging to the physical section of the track circuit are in good condition, that is, whether the rails in the physical section of the track circuit are broken or other abnormal conditions occur, the first communication train can be dispatched to clean the physical section of the track circuit with an occupied usage status at a preset cleaning speed, so that the usage status of the virtual section of the track circuit corresponding to the physical section of the track circuit is updated to idle, and a speed limit instruction is sent to the ATP through the RBC to control the speed limit (up to 45km / h) of the train passing through the physical section of the track circuit where the signal wayside equipment failure occurs.
[0057] Optionally, in an embodiment of the present invention, in the event of a signal wayside equipment failure, if the track circuit physical section is isolated or cleared, the usage status of the track circuit physical section is still occupied, that is, the track circuit MA generated by the track circuit according to the usage status of the track circuit physical section is still prohibited for the track section to which the track circuit physical section belongs, while the usage status of the track circuit virtual section corresponding to the track circuit physical section is idle, and the wireless MA generated by the RBC according to the usage status of the track circuit physical section is allowed for the track section to which the track circuit virtual section belongs. In order to avoid stopping due to taking the shorter driving permit end point after redundant comparison of the two, it is necessary to add an on or off control function to the existing driving permit hyperbola comparison function.
[0058] Furthermore, the RBC can send a command to disable the existing hyperbola comparison function for the driving permit to the onboard equipment of trains within a preset transmission range. After the train exits the physical track circuit section where the signal trackside equipment failure occurred, the RBC can send a command to enable the existing hyperbola comparison function to the onboard equipment of the train. The preset transmission range can be adaptively set by those skilled in the art, for example, to a range of six block sections from the physical track circuit section where the signal trackside equipment failure occurred.
[0059] Optionally, in an embodiment of the present invention, regardless of whether the driving permit hyperbola comparison function is turned on or off, a new function will be added to the on-board equipment to verify the legitimacy of the wireless MA sent by the RBC, that is, the TSRS is responsible for providing the location information of the current communication train to the on-board equipment, and the ATP is responsible for checking whether there are other communication trains within the range of the received wireless MA. If the check finds that there are still communication train envelopes within the range of the wireless MA provided by the RBC, the ATP determines that the current wireless MA is illegal and disconnects the communication connection with the RBC. The hybrid train control system automatically downgrades to the first train control system. If the MA is legal, the ATP continues to compare with the existing track circuit information code sequence, selects the shorter driving permit end point, and controls the train operation.
[0060] By adding the function of verifying the legality of wireless MA to the on-board equipment, the safety and reliability of heterogeneous comparison is further enhanced, thereby improving the safety of train operation, compared with the on-board equipment only comparing wireless MA with track circuit MA for driving permit hyperbolic comparison.
[0061] The technical solution of the embodiment of the present invention adopts the second train control system to control the train operation when the signal wayside equipment fails, and adopts the first train control system to control the train operation when the communication wayside equipment fails. This ensures safe and efficient operation after the track circuit failure, further improves the stability and redundancy of the train control system, and reduces the pressure on personnel to maintain line equipment.
