At the same time, there are also higher requirements and standards for the transportation efficiency of urban rail.
[0003] The urban rail is a high-capacity, convenient, fast, and public transportation rail transit system that connects the central city of the metropolitan area to the surrounding towns. The automatic train turnaround solution of the urban rail is mainly aimed at train operations in the city.

[0049] The present embodiment is described in detail below, and examples of the embodiment are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0050] The automatic return simulation system and method based on a real train control system of this embodiment will be described below with reference to the accompanying drawings.

Figure 1 As shown, the automatic return simulation system 10 based on the real train control system includes: an environment data sending module 11, a real train operation module 12, a virtual train operation module 13 and a simulation platform 14.
[0052] Among them, the environmental data sending module 11 is used to send the real environmental data of the railway site to the simulation platform 14; the real train operation module 12 and the virtual train operation module 13 are respectively used to provide the simulation platform 14 with the operation information of the real train and the virtual train; the simulation platform 14 is respectively connected to the environmental data sending module 11, the real train operation module 12 and the virtual train operation module 13, and the simulation platform 14 is used to simulate the operation scenarios of the real train and the virtual train according to the environmental data, the operation information of the real train and the operation information of the virtual train, and test the automatic return operation of the train in the simulated operation scenario.
[0053] The environmental data sending module 11 includes CTC (Centralized Traffic Control) and an interlocking unit, and the CTC and the interlocking unit are used to send track circuit data, station equipment data and turnout information data to the simulation platform 14 .
[0054] The automatic train reversal solution of this embodiment is mainly to simulate the actual train operation scenario. Under the simulation of the train operation scenario, combined with the actual C2+ATO (Chinese Train Control System level2+Automatic Train Operation) equipment, the manual reversal is transformed into automatic reversal.
[0055] Specifically, the simulation platform 14 can be connected and interacted with the real CTC and interlocking unit and other equipment on site, so as to adopt the real data of the urban rail site, such as track circuit data, station equipment data and turnout information data, and restore the real operating environment and train operating environment on site to the greatest extent. After obtaining the real data on site, the train operation scene is simulated according to the train operation information of the real train operation module 12 and the virtual train operation module 13, and the automatic return solution is realized in combination with the real C2+ATO equipment under the simulation of the train operation scene.
[0056] In one embodiment of the present invention, the real train has two locomotive ends, each locomotive end is provided with a real train operation module 12, such as Figure 2 As shown, the real train operation module 12 includes: a train automatic operation unit 121, a train automatic protection unit 122 and an on-board adapter 123.
[0057] Among them, the train automatic operation unit 121 is used to send the automatic operation information of the train to the outside; the train automatic protection unit 122 is respectively connected to the train automatic operation unit 121 of the corresponding front end and the train automatic protection unit 122 of the other front end, and the train automatic protection unit 122 is used to obtain the speed limit protection information of the train according to the automatic operation information of the corresponding front end, and synchronize information with the train automatic protection unit 122 of the other front end; the on-board adapter 123 is respectively connected to the train automatic operation unit 121 of the corresponding front end, the train automatic protection unit 122, the on-board adapter 123 of the other front end and the simulation platform 14, and the on-board adapter 123 is used to send the automatic operation information and speed limit protection information of the real train to the simulation platform 14, and synchronize information with the on-board adapter 123 of the other front end.
[0058] The automatic train operation unit 121 in this embodiment may be an ATO (Automatic Train Operation) device, and the automatic train protection unit 122 may be an ATP (Automatic Train Protection) device. Figure 3As shown, the train automatic protection unit 122 is connected to the train automatic protection unit 122 at another locomotive end through a wireless LTE (Long Term Evolution) environment. In this embodiment, the train automatic protection unit 122 can synchronize information with the train automatic protection unit 122 at another locomotive end through the wireless LTE environment, such as synchronization of train speed limit protection information, train automatic operation information, etc.
[0059] Specifically, Figure 3 As shown, when the train automatically turns back, the on-board adapter at end A can interact with the train automatic operation unit 121 and the train automatic protection unit 122 and the trackside at end A respectively, and the on-board adapter at end B can interact with the train automatic operation unit 121 and the train automatic protection unit 122 and the trackside at end B respectively, and the two train automatic protection units 122 can interact through the wireless LTE environment to synchronize data, and the train automatic operation unit 121 and the train automatic protection unit 122 at each end can also interact, and can manipulate the corresponding on-board adapter 123 at the same time.
[0060] In this embodiment, the simulation system can simulate automatic train protection, automatic train operation, the on-board adapter 123 and the underlying signal equipment of the station, etc. It can be understood that the on-board adapter 123 can send train operation information such as speed limit protection information of the train and automatic operation information of the train to the simulation platform 14, so as to realize the simulation of the operation scene of the real train.
[0061] In this embodiment, the on-board adapters at both ends are connected, and the on-board devices at both ends, such as ATP, are connected through a wireless LTE environment, so that the function of two-end communication between the train heads can be realized, and it can be ensured that the train can send the required status of the on-board devices to the C2+ATO device, i.e., the ATO device, in real time during operation. The on-board adapter 123 can simulate real train equipment, connect the real on-board devices ATP and ATO, and be connected to the simulation platform 14, so as to simulate the real train operation scene on site, and then the reliability and stability of the on-board software combined with the real equipment can be experimented and tested.
[0062] In one embodiment of the present invention, Figure 4 As shown, the virtual train operation module 13 includes: a virtual train simulation unit 131 , a first virtual train automatic protection unit 132 , a first virtual on-board adapter 133 , a second virtual train automatic protection unit 134 and a second virtual on-board adapter 135 .
[0063] Among them, the virtual train simulation unit 131 is connected to the simulation platform 14, and the virtual train simulation unit 131 is used to simulate the virtual train and the train automatic operation unit 121, and send the automatic operation information and speed limit protection information of the virtual train to the simulation platform 14; the first virtual train automatic protection unit 132 is connected to the virtual train simulation unit 131 through the first virtual on-board adapter 133, and the first virtual train automatic protection unit 132 is used to obtain the first virtual speed limit protection information of the virtual train according to the automatic operation information of the virtual train, and send the first virtual speed limit protection information to the virtual train simulation unit 131 through the first virtual on-board adapter 133; the second virtual train automatic protection unit 134 is connected to the virtual train simulation unit 131 through the second virtual on-board adapter 135, and the second virtual train automatic protection unit 134 is used to obtain the second virtual speed limit protection information of the virtual train according to the automatic operation information of the virtual train, and send the second virtual speed limit protection information to the virtual train simulation unit 131 through the second virtual on-board adapter 135; wherein, the first virtual train automatic protection unit 132 is also connected to the second virtual train automatic protection unit 134 to synchronize the virtual speed limit protection information.
[0064] Specifically, Figure 5 As shown, the virtual train simulation unit 131 can be connected to the simulation platform 14, and transmit the operation information of the virtual train, such as the virtual speed limit protection information and the automatic operation information of the virtual train, to the simulation platform 14. The virtual train simulation unit 131 is connected to the virtual train automatic protection unit and the wireless LTE environment at both ends through the virtual vehicle adapter, and transmits the corresponding train information, such as the automatic operation information of the virtual train, to the virtual train automatic protection unit.
[0065] In this embodiment, the virtual train simulation unit 131 can simulate the train and the train automatic operation equipment ATO, and connect with the virtual version of the train automatic protection unit, so as to simulate and experiment with the environment and requirements of the urban rail site, and then conveniently and quickly allow the on-board equipment such as ATO and ATP to perform preliminary debugging and experiments. In this embodiment, the virtual train simulation unit 131 can also be combined with a virtual on-board adapter, so as to simulate the scene of combining a virtual train with a real train in the laboratory.
[0066] In one embodiment of the present invention, Figure 6 As shown, the virtual train operation module 13 may further include a train management unit 136. The train management unit 136 may be connected to the simulation platform 14, the first virtual vehicle adapter 133, and the second virtual vehicle adapter 135, respectively. The train management unit 136 is used to obtain train operation data from the simulation platform 14, perform data classification processing, and distribute the classified train operation data to the first virtual vehicle adapter 133 and the second virtual vehicle adapter 135 for data synchronization.
[0067] Please continue to refer to Figure 3 and Figure 5 The environment data sending module 11 is also connected to the real train operation module 12 and the virtual train operation module 13 respectively, and the CTC is used to send the train operation plan data to each train automatic protection unit 122, the first virtual train automatic protection unit 132 and the second virtual train automatic protection unit 134 respectively, so that the real train and the virtual train run according to the train operation plan data. Among them, the CTC also sends the train operation plan data to the virtual train simulation unit 131 through the simulation platform 14.
[0068] In this embodiment, the automatic protection units at both ends of the train can obtain the operation plan data issued by the CTC through the wireless LTE environment connection, and synchronize information during automatic return and automatic end change. The virtual train simulation unit 131 can also obtain the operation plan data issued by the CTC through the simulation platform 14.
[0069] It should be noted that the simulation platform 14 can also send transponder message information to the on-board adapter 123, the first virtual on-board adapter 133 and the second virtual on-board adapter to simulate the flow of transponder message information between the on-board adapters and ensure the working state of the on-board equipment when the train is running.
[0070] In one embodiment of the present invention, in the operation scenario of a real train, the train automatic operation unit 121 and the train automatic protection unit 122 can periodically send a return valid signal to the on-board adapter 123 so that the real train can perform automatic return and end change operations. In the operation scenario of a virtual train, the first virtual train automatic protection unit 132, the second virtual train automatic protection unit 134 and the virtual train simulation unit 131 can periodically send a return valid signal to the corresponding first virtual on-board adapter 133 and the second virtual on-board adapter 135 so that the virtual train can simulate automatic return and end change operations.
[0071] Figure 7 This is a flow chart of an automatic return simulation method based on a real train control system provided by an embodiment of the present invention. Figure 7 As shown, the method includes:
[0072] Step S1: Sending a return valid signal to the vehicle adapter.
[0073] Step S2: determining whether the on-board adapter is in a turnaround state before receiving the turnaround valid signal, and if it is determined that the on-board adapter is not in the turnaround state, further determining whether the on-board adapter is a turnaround end executed by the conductor.
[0074] Step S3: when it is determined that the on-board adapter is the turnaround end for the conductor, the on-board adapter is set to the turnaround state, and the on-board adapter sends the turnaround state setting information to another on-board adapter.
[0075] During the automatic reversal process, the on-board adapter in the active state will transmit the reversal state or reversal mode setting information to the on-board adapter in the inactive state in real time. Among them, after the on-board adapter switches from the inactive state to the active state, the train automatic protection unit can also output an ATO activation signal to the on-board adapter, so that the train automatic operation unit ATO can control the train. The on-board adapter in this example can be an on-board adapter in a real train operation scenario, or a virtual on-board adapter in a virtual train operation scenario.
[0076] Specifically, Figure 8 As shown, during the automatic reversal and end change of the train, ATP and ATO will periodically output a reversal valid signal to the on-board adapter. After receiving the signal, the on-board adapter first determines whether it is in the reversal state before receiving it. If so, no processing is performed. If not, it is further determined whether the on-board adapter is the train conductor performing the reversal end and has not received the reversal state of the other end before. If so, the on-board adapter is set to the reversal state and the reversal state is regularly output to the other on-board adapter. If not, it is considered that the current train is performing an automatic end change operation, and the current end is switched from an inactive state to an active state, and the vehicle deletion information is sent to the trackside simulation in the simulation platform, and the vehicle addition information is sent after the first preset time, such as 200 milliseconds, and the timing is started. If the vehicle addition feedback information is received after the second preset time, such as 1 minute, the process is considered to be correct, and the information is further saved, and the ATO activation information output by the train automatic protection unit is transmitted to the ATO, and then the ATO is enabled to start vehicle control. If the vehicle addition feedback information is not received after 1 minute, it is considered that there is an error in the environment, the train is deleted, and the program is terminated.
[0077] In one embodiment of the present invention, when the vehicle adapter performs information synchronization, the method further includes: receiving an information packet and determining the source of the information packet; managing the vehicle adapter's own state according to the source of the information packet and the current activation state of the vehicle adapter, and processing the information packet accordingly. Before receiving the information packet, the validity of the information packet is also verified.
[0078] The method of managing the state of the vehicle adapter according to the source of the information packet and the current activation state of the vehicle adapter, and processing the information packet accordingly, includes:
[0079] If the information packet comes from the simulation platform and the vehicle adapter is in an activated state, the type of information in the information packet is further determined; if the information in the information packet is operating status information, its own state is updated and the updated information is sent to another vehicle adapter; if the information in the information packet is transponder message information, the transponder message information is modified and sent to another vehicle adapter; if the information packet comes from another vehicle adapter and the vehicle adapter is in an inactivated state, its own state is updated and the information in the information packet is saved.
[0080] During the operation of the train, the flow of balise message information, train mileage, train offset, track circuit information, etc. between the onboard adapters at both ends of the train can be simulated, specifically sent from the onboard adapter in an activated state to the onboard adapter in an inactivated state on the other side of the train, so as to ensure the working state of the onboard equipment while the train is running. If the onboard adapter receives balise message information from the simulation platform during operation, the onboard adapter in an activated state can update its own information, and send the modified balise message information to the onboard adapter in an inactivated state. Among them, the onboard adapter in an inactivated state can directly discard the balise information packet received from the simulation platform.
[0081] Specifically, Fig. 9 As shown, during the normal operation of the train, after receiving the information packet, the on-board adapter will check whether the current information packet is valid. If it is invalid, it will be discarded directly. After the detection is valid, the source of the current information packet can be determined. If it comes from the simulation platform and the on-board adapter is in an activated state, the current information packet type will continue to be determined. If it is running status information, its own status will be updated and sent to the on-board adapter in an inactive state. If it is a transponder message information, the transponder position in the transponder information packet will be modified, and then its own status will be updated and sent to the on-board adapter in an inactive state. If the on-board adapter is currently in an inactive state, the information packet will be discarded directly. If the information packet comes from the on-board adapter and the current on-board adapter is in an activated state, the information packet will be discarded directly. If the current on-board adapter is in an inactive state, its own status will be updated and the information in the information packet will be saved.
[0082] In summary, the present invention can present the real operation scene of the urban rail station to the maximum extent according to the operation scene data of the actual urban rail station and the operation scene equipment of the actual urban rail station; and the present invention can simulate the scene in which only the virtual train runs in the environment, the operation scene in which the virtual train and the real train run at the same time in the environment, and the operation scene in which only the real train runs in the environment; and the on-board adapter in the simulation system of the present invention and the train management unit in the virtual environment can synchronize and process data during the operation of the train, and when the train is in the process of automatic reversal and end change operation, the on-board adapter can perform additional data synchronization, and the train automatic protection units at both ends of the train can be connected through the wireless LTE environment, so as to realize the synchronization of the information required for the train end change and reversal operation, and save the driver's walking time in the case of a single driver, solve the problem of manual end change operation before, and increase the operation efficiency; furthermore, the train automatic protection in the present invention can output additional reversal effective signals so that the train can perform automatic reversal and end change operations, and the simulation platform in the present invention can also be connected to railways and train equipment in other operating environments, and has good compatibility.
