[0029] Figure 1 A flowchart of a cloud simulation method for simulating train operation provided in an embodiment of the present invention.

[0030] Figure 2 This is a structural block diagram of a cloud simulation system for simulating train operation, provided as an embodiment of the present invention. Detailed Implementation

[0031] The following describes this embodiment in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0032] The cloud simulation method and system for simulating train operation of this embodiment are described below with reference to the accompanying drawings.

[0033] Figure 1 This is a flowchart illustrating a cloud simulation method for simulating train operation according to an embodiment of the present invention. Figure 1 As shown, the method includes:

[0034] Step S1: Identify the device that needs to be directly manipulated and deploy the device at the front end, wherein the device includes multiple first CTC units.

[0035] like Figure 2 As shown, the multiple first CTC units include at least: CTC train dispatching equipment, CTC auxiliary dispatching equipment, CTC dispatching and monitoring equipment, CTC train operation terminal, CTC line occupancy board, FAS dispatching console and train driver's console, among which the CTC train dispatching equipment, CTC auxiliary dispatching equipment and CTC dispatching and monitoring equipment are central equipment.

[0036] In this embodiment, the front end may include the software / devices that the actual user needs to operate, and it needs to be deployed as a separate hardware device, just like on-site. Therefore, the devices that need to be directly manipulated can be identified and deployed on the front end in the same way as on-site deployment environment.

[0037] Step S2: Identify the multiple second CTC units and simulation systems to be deployed, and deploy the multiple second CTC units and simulation systems on the backend cloud platform to simulate train operation on the backend cloud platform.

[0038] In this embodiment, software or devices that are not directly manipulated by the user, including various backend and simulation programs, can be deployed on a backend cloud platform. Then, the frontend and backend are set up in the same local area network and communicate with each other through the network.

[0039] like Figure 2 As shown, the multiple second CTC units include at least: an autonomous machine, a CTC communication server, a GSM-Ri (Global System for Mobile Communications – Railway interface) system interface server, a TSRi temporary speed limit interface server, and an RBCi radio block center interface server.

[0040] The simulation system includes at least: simulated interlocking, simulated RBC (Radio Block Center), simulated TSRS (Temporary Speed ​​Restriction Server), simulated GSM-R, simulated train trackside, and simulated TMIS (Train Management Information System) software.

[0041] It should be noted that the cloud simulation system built using this cloud simulation method can meet the environmental requirements for simulating train operation from CTCS-0 to CTCS-4 levels, thus facilitating system demonstration and training.

[0042] In one embodiment of the present invention, when deploying multiple second CTC units and a simulation system on a backend cloud platform, the method further includes: allocating corresponding operating system platforms according to the actual architecture of each application software to be deployed in the multiple second CTC units and the simulation system, and deploying each application software within the corresponding operating system platform.

[0043] Specifically, the backend cloud platform can allocate various operating system platforms according to the real device / software architecture, and then deploy real or simulated system application software within each operating system of the backend cloud platform.

[0044] In one embodiment of the present invention, the first CTC unit can communicate with the autonomous machine, the GSM-Ri system interface server, the TSRi temporary speed limit interface server, and the RBCi radio block center interface server through the CTC communication server.

[0045] For example, the CTC train dispatching equipment in the first CTC unit can issue a train operation plan, which is then sent to the autonomous machine via the CTC communication server. The autonomous machine then notifies the analog interlocking software to open the line signals within the station, thereby facilitating the start of the train.

[0046] In one embodiment of the present invention, the autonomous machine can communicate with the GSM-Ri system interface server, the TSRi temporary speed limit interface server, and the RBCi radio block center interface server through the CTC communication server.

[0047] For example, the autonomous machine can communicate with the simulated RBC in the simulation system through the CTC communication server and the RBCi radio block center interface server in order to notify the simulated RBC of open section signals.

[0048] In one embodiment of the present invention, when there is a communication requirement between the first CTC units, communication can be carried out through a CTC communication server.

[0049] For example, when the CTC train dispatching equipment issues a dispatching command, it transmits the work tasks / commands issued by the center. After passing through the CTC communication server, the command is sent to the CTC train operation terminal so that the duty officer using the train operation terminal can be informed and conduct text information exchange and communication between the center and the station.

[0050] To more clearly illustrate the cloud simulation method for simulating train operation in this embodiment, the following section provides a detailed explanation of the cloud simulation method from the perspective of the first CTC unit:

[0051] For CTC (Centralized Train Control) equipment, the railway bureau's central dispatcher can issue train operation plans via the CTC equipment. These plans are then sent to the automated control unit (ACU) through the CTC communication server. The ACU then notifies the interlocking system to open the track signals within the station, allowing the train to start. In this implementation, the ACU can also communicate with the simulated RBC (Rail Block Center) via the CTC communication server and the RBCi radio block center interface server to notify the simulated RBC to open the section signals.

[0052] It should be noted that the train operation plan can also be sent to the train communication server on the backend cloud platform via the CTC communication server. The train TMIS receives the train operation plan, the trackside equipment prepares the train operation signals, and the train TTMS transmits the train's direction and position in real time to the visual simulation (driver's cab view) system and the bird's-eye view simulation system, so that the latter two systems can change their views in real time.

[0053] The railway bureau's central dispatcher can also issue dispatching orders on the CTC train dispatching equipment, transmitting the work tasks / orders issued by the center. These orders are then sent to the CTC train operation terminal via the CTC communication server, so that the duty officer using the train operation terminal can be informed, enabling text information exchange and communication between the center and the station.

[0054] It should be noted that, for dispatching commands, the central dispatcher / station duty officer can also send temporary speed limit dispatching commands, which are transmitted to the simulated TSR via the CTC communication server and the TSRi temporary speed limit interface server, allowing the latter to command the train to limit its speed. The autonomous machine can also send wireless train route advance notice commands (a special format of dispatching commands), which are sent to the FAS dispatching console via the CTC communication server, the GSM-Ri system interface server, and the intelligent interface server. The central dispatcher / station duty officer can also send wireless dispatching commands, which are sent to the FAS dispatching console via the CTC communication server, the GSM-Ri system interface server, and the intelligent interface server. In this embodiment, the FAS dispatching console can set the train number to be operated and transmit it to the GSM-Ri system interface server, which then sends it to the autonomous machine via the CTC communication server.

[0055] For CTC auxiliary dispatching equipment, the simulated interlocking software can send signal status to the automated control unit, which then transmits it to the railway bureau's central dispatching unit via the CTC communication server. Alternatively, the train's TMIS can transmit the real-time train position to the CTC communication server via the train communication server, and then to the CTC auxiliary dispatching equipment. In this embodiment, the CTC auxiliary dispatching equipment can also view the relevant signal / train status during real-time train operation and can also issue commands to the automated control unit and the simulated interlocking software to change the signal status.

[0056] For CTC (Central Train Control) monitoring equipment, the analog interlocking software can send signal status to the automatic control unit, which then transmits it to the railway bureau's central CTC monitoring equipment via the CTC communication server. Alternatively, the train's TMIS (Train Train Information System) can transmit the real-time train location to the CTC communication server via the train communication server, and then to the CTC monitoring equipment. It's important to note the difference between assistant dispatchers and monitoring units: assistant dispatchers have processing authority, while monitoring units only have viewing authority; assistant dispatchers can only display / process the status of one station at a time, while monitoring units display the status of all stations along the entire line.

[0057] The CTC (Train Control Center) terminal functions similarly to the central dispatcher / assistant dispatcher / monitor, but is deployed at the station level. Specifically, it can receive train plans from the central dispatcher via the CTC communication server, and can also modify train plans and send them to the automated control unit. It can also receive dispatch commands from the central dispatcher via the CTC communication server, and can send dispatch commands to the central dispatcher via the CTC communication server, or send them to the FAS (Front-Action System) dispatch console via the CTC communication server, GSM-Ri system interface server, and intelligent interface server. In this embodiment, the CTC terminal can also directly send train signal instructions to the automated control unit and simulated interlocking system, and can also view the signal status of the current station and neighboring stations.

[0058] For CTC (Conditional Traffic Control) board, train plans can be received from the center through the CTC communication server. Train plans can also be modified and sent to the automatic control machine and simulated interlocking, or shunting operation plans can be sent to the automatic control machine and simulated interlocking.

[0059] For the FAS dispatch console, train route prediction messages can be obtained through the communication link between the intelligent interface server, the CTC communication server, and the autonomous machine. Train dispatching commands can also be obtained through the communication link between the intelligent interface server, the CTC communication server, and the CTC train dispatching equipment. In this embodiment, the FAS dispatch console can also forward the CTC information obtained through the above channels to the FAS system and display it on the subsystem of the train driver's console.

[0060] The driver can view the train's control panel via a display screen. Figure 2 The "Driver Visual Simulation" system displays the real-time view outside the driver's window at the train's current location. Of course, the driver can also start / stop and decelerate / accelerate the train via the cab, simulating actual train operation through the train's TMIS system. Simultaneously, information such as the train's position and speed is transmitted to the front-end CTC system via the train communication server and CTC communication server, allowing it to be viewed through the aforementioned CTC train dispatching equipment, CTC auxiliary dispatching equipment, CTC dispatching monitoring equipment, CTC train operation terminal, and CTC busy signal board.

[0061] Furthermore, the present invention also provides a cloud simulation system for simulating train operation. The system includes multiple first CTC units, multiple second CTC units, and a simulation system. The multiple first CTC units are deployed at the front end for sending train operation commands, which include at least a train operation plan or a scheduling command. The multiple second CTC units and the simulation system are deployed at the back end cloud platform for simulating train operation on the back end cloud platform according to the train operation commands.

[0062] It should be noted that the specific implementation of the cloud simulation system for simulating train operation in this embodiment can be found in the specific implementation of the cloud simulation method for simulating train operation described above. To avoid redundancy, it will not be repeated here.

[0063] In summary, this invention divides the simulated train operation into a front-end part and a back-end part. Specifically, the devices or software directly used by the user are placed on independent hardware devices and set up at the front end, while the various application software or simulation software in the back end are set up to run on the cloud platform. This allows for flexible configuration of the system environment required by each application software without changing the user's device usage habits. It is easy to deploy and saves investment. Furthermore, this invention can realize train operation simulation through specific deployment methods and the construction of corresponding simulation systems.

[0064] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
