[0026] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.
[0027] A method and device for switching a control system of a train according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.
[0028] Figure 1 A train control system switching method provided by an embodiment of the present application is as follows: Figure 1 As shown, the method includes:
[0029] S101, in response to a received system switching message, obtaining a system switching point of a train on a current route, where the system switching point is a location where different system routes meet;
[0030] S102, obtaining a switching point speed limit corresponding to the system switching point, and determining a target travel speed of the train on the current travel route according to the switching point speed limit, so that the current system control system of the train controls the train to travel on the current travel route according to the target travel speed;
[0031] S103. If the real-time speed of the train is lower than or equal to the target speed when the train reaches the mode switching point, the background mode control system is adjusted to the new current mode control system, and the current mode control system is adjusted to the new background mode control system.
[0032] It can be understood that the control system switching method of a train provided in this example is applied to a train, which is provided with two independent interfaces, each independent interface is connected to a standard control system, and when the train is running, the standard control system that controls the train is the current standard control system, and the other standard control system is the background standard control system; it can be understood that the current standard control system of the train corresponds to the standard of the current route of the train.
[0033] For example, taking the case where a train includes a CTCS2 control system and a CBTC control system, when the CTCS2 control system controls the train to travel on a CTCS2 route, the CTCS2 control system is the current control system and the CBTC control system is the background control system; when the CBTC control system controls the train to travel on a CBTC route, the CBTC control system is the current control system and the CTCS2 control system is the background control system.
[0034] Specifically, since there is a need for trains to interconnect on routes of different standards, in order to make the current standard control system of the train correspond to the standard of the train's current route, when the train enters the standard route corresponding to the background standard control system, it is necessary to adjust the background standard control system to the new current standard control system, and adjust the current standard control system to the new background standard control system.
[0035] Continuing with the above example, in order to realize the switching of the system control system during the train's travel, this example will accept a system switching message, which is used to indicate that the system of the current route will be switched within a preset time / preset distance. The preset time and preset distance are both values set by relevant personnel based on actual needs; the system switching message can be issued by the user, or it can be issued by the ground equipment of the current route.
[0036] It can be understood that in order to enable both the current standard control system and the background standard control system to be ready for switching, both the current standard control system and the background standard control system will receive the standard switching message; wherein, after receiving the standard switching message, this example will further obtain the standard switching point of the train on the current route, and the standard switching point is the location point where different standard routes meet. When the train reaches the standard switching point, it will enter the standard route corresponding to the background standard control system; exemplarily, there are CBTC standard routes and CTCS2 standard routes, and the junction point of the CBTC standard route and the CTCS2 standard route is used as the standard switching point.
[0037] In some examples, after obtaining the standard switching point, this example will further obtain the switching point speed limit corresponding to the standard switching point, and determine the target speed of the train on the current route based on the switching point speed limit; wherein, the above-mentioned switching point speed limit may be pre-stored in the current standard control system and / or the background standard control system, and the switching point speed limit may also be input by the user or issued by the ground equipment of the current route.
[0038] Continuing with the above example, the above-mentioned steps of obtaining the switching point speed limit corresponding to the standard switching point and determining the target speed of the train on the current route based on the switching point speed limit can be executed by the current standard control system and / or the background standard control system. In order to avoid occupying the system resources of the current standard control system and causing safety hazards caused by the current standard control system being stuck, this example preferably uses the background standard control system to execute the steps of obtaining the switching point speed limit corresponding to the standard switching point and determining the target speed of the train on the current route based on the switching point speed limit.
[0039] After determining the target speed, the current standard control system of this example will control the train to travel on the current route according to the target speed; illustratively, the background standard control system executes to obtain the switching point speed limit corresponding to the standard switching point, and determines the target speed of the train on the current route according to the switching point speed limit, and then sends the target speed to the current standard control system, the main control system inserts the target speed into its own vehicle control curve, and controls the train to run according to the target speed limit. In some examples, in order to ensure the smoothness when the background standard control system is adjusted to the new current standard control system, the present application determines the switching point speed limit by the background standard control system, and then the current standard control system determines the target speed of the train on the current route according to the switching point speed limit, so that when the background standard control system is adjusted to the new current standard control system and the current standard control system is adjusted to the new background standard control system, there will be no overspeeding, resulting in triggering braking.
[0040] It can be understood that in the process of controlling the train to travel on the current route according to the target travel speed, the current standard control system and / or the background standard control system will determine the real-time position and real-time speed of the train. The above-mentioned target travel speed is the safe travel speed of the train when it travels to the standard switching point. If the real-time speed of the train when it travels to the standard switching point is higher than the target travel speed, it indicates that there is a safety hazard in the speed of the train, and the background standard control system of the train cannot be safely adjusted to the new current standard control system. Therefore, this example will issue a safety alarm so that the current standard control system can adjust the speed or repair the train in time; if the real-time speed of the train is lower than or equal to the target travel speed when the train travels to the standard switching point, it indicates that the train is traveling normally and can be safely switched to the background standard control system. Therefore, when the train travels to the standard switching point, the real-time speed of the train is lower than or equal to the target travel speed. This application will adjust the background standard control system of the train to the new current standard control system, and adjust the current standard control system to the new background standard control system, so as to achieve the effect of controlling the train through the standard control system corresponding to the standard line.
[0041] For example, Figure 2 As shown, in this example, the current standard control system and the background standard control system receive the standard switching message, at which time the current standard control system and the background standard control system are ready for the master-slave switching; the background standard control system calculates the target driving speed and sends it to the current standard control system; the current standard control system inserts the target driving speed into its own vehicle control curve, and controls the train to run at the above target driving speed limit; determines whether the train has reached the standard switching point, if the train reaches the standard switching point (in this example, since the train runs at the above target driving speed limit, the default real-time speed of the train must be lower than or equal to the target driving speed), the background standard control system is adjusted to the new current standard control system, and the current standard control system is adjusted to the new background standard control system.
[0042] According to the technical solution provided in the embodiment of the present application, in response to the received system switching message, the system switching point of the train on the current route is obtained, and the system switching point is the location point where different system routes meet; the switching point speed limit corresponding to the system switching point is obtained, and the target speed of the train on the current route is determined according to the switching point speed limit, so that the current system control system of the train controls the train on the current route according to the target speed; if the real-time speed of the train is lower than or equal to the target speed when the train reaches the system switching point, the background system control system is adjusted to the new current system control system, and the current system control system is adjusted to the new background system control system, so that when the train enters a different system route, it can seamlessly switch to the system. The method provides a background control system corresponding to the standard route, and controls the train based on the background control system. The method enables the train to have two independent standard control systems, ensuring the independence and compliance of the two standard control systems, while realizing operation under different standards, and realizing manual and automatic switching of standards, so that the train can be interconnected on different standard routes, and obtain and apply the target driving speed in advance, so that the train can complete the switching of the standard control system at an appropriate speed, reducing the possible failures or delays in the switching process of the standard control system, and because the train can smoothly switch between routes of different standards, it reduces the downtime and maintenance requirements caused by switching failures, thereby reducing operating costs and maintenance complexity. It avoids the problem in related technologies that trains cannot be interconnected on different standard routes.
[0043] In some embodiments, the train includes two different standard control systems, and the different standard control systems are respectively connected to different independent interfaces of the train, and each standard control system includes an on-board host, an interactive interface, a speed sensor, an accelerometer, and a transponder transmission module; the different standard control systems are communicated with each other, and when the train is running, one standard control system is the current standard control system and the other standard control system is the background standard control system. Among them, each standard control system includes an on-board host, an interactive interface, a speed sensor, an accelerometer, and a transponder transmission module, so that the two standard control systems operate completely independently and there will be no conflict between the two standard control systems.
[0044] For example, taking the two standard control systems, CTCS2 standard control system and CBTC standard control system, as examples, the CTCS2 standard control system and the CBTC standard control system respectively use independent peripherals, the independent peripherals of the CTCS2 standard control system are used to complete the CTCS2 (including ATO) function, and the independent peripherals of the CBTC standard control system are used to complete the CBTC function. And the CTCS2 standard control system and the CBTC standard control system are connected in communication, so as to realize the interactive standard switching speed limit, control instructions and other information to ensure the smooth switching of the standard control system. The trains equipped with the CTCS2 standard control system and the CBTC standard control system can run on the CTCS2 line and can also run on the CBTC standard control system line. Since the CTCS2 standard control system and the CBTC standard control system in this example both maintain the original standard host, the independence and compliance of the CTCS2 standard control system and the CBTC standard control system are guaranteed, and the trains can run under different standards, and the manual and automatic switching of standards is also realized.
[0045] Continuing with the above example, Figure 3 As shown, the independent peripherals corresponding to the CTCS2 control system on the train include: 1 CTCS on-board host (main control), 2 DMIs (interactive interfaces), 2 speed sensors, 1 radar / 3 accelerometers, 2 BTM antennas (transponder transmission modules), and 2 TCR antennas; the independent peripherals corresponding to the CBTC control system include: 1 CBTC on-board host (main control), 1 DMI, 2 speed sensors, 3 accelerometers, 1 BTM antenna (transponder transmission module), and 1 set of on-board LTE-M equipment. In some examples, in order to ensure the safety of the train traveling in both the front and rear directions, the CTCS2 control system and the CBTC control system are configured at both ends of the train, that is, there are two CTCS2 control systems and two CBTC control systems on the train; among them, the on-board hosts of the CBTC control systems at both ends are connected by the head-to-tail through-line communication, and the on-board hosts of the CTCS control systems at both ends are connected by another head-to-tail through-line communication. The CTCS2 control system and the CBTC control system are connected by communication via RS422, RS232, Ethernet or any other method to achieve information exchange.
[0046] In some embodiments, Figure 4 As shown, the target speed of the train on the current route is determined according to the speed limit at the switching point, including:
[0047] S401, obtaining the speed limit of the current route and the speed limit of the train;
[0048] S402: The lowest speed limit among the speed limit of the current travel route, the speed limit of the train, and the speed limit at the switching point is taken as the target travel speed.
[0049] It can be understood that the target driving speed is the safe driving speed for the train to travel to the mode switching point, wherein, during the travel on the current route, if the real-time speed of the train exceeds the speed limit of the current route, the train will be subject to safety hazards such as derailment; if the real-time speed of the train exceeds the speed limit of the train, there will be safety hazards such as a longer braking distance or inability to brake; similarly, when the real-time speed of the train exceeds the speed limit of the switching point, the train will also be subject to safety hazards such as derailment.
[0050] Based on the above reasons, this example will compare the speed limit of the current route, the speed limit of the train and the speed limit of the switching point, and then determine the minimum speed limit from the display of the current route, the speed limit of the train and the speed limit of the switching point, and use the minimum speed limit as the target travel speed, so that when the main control unit controls the train according to the target travel speed, it will not exceed any of the speed limit of the current route, the speed limit of the train and the speed limit of the switching point, thereby improving the driving safety of the train.
[0051] According to the technical solution provided in the embodiment of the present application, the speed limit of the current driving route and the speed limit of the train are obtained; the lowest speed limit among the speed limit of the current driving route, the speed limit of the train and the speed limit at the switching point is used as the target driving speed, so that when the main control unit controls the train according to the target driving speed, it will not exceed any of the speed limit of the current driving route, the speed limit of the train and the speed limit at the switching point, thereby improving the driving safety of the train.
[0052] In some embodiments, Figure 5 As shown, if the train travels to the system switching point at the target speed, the background system control system is adjusted to a new current system control system. Before the current system control system is adjusted to a new background system control system, the method further includes:
[0053] S501, periodically collecting control parameters of the train controlled by the current standard control system;
[0054] S502: Send the control parameters to the background standard control system, so that the background standard control system obtains the status of the train based on the control parameters.
[0055] In order to ensure that when the train reaches the standard switching point, the background standard control system of the train is adjusted to the new current standard control system, and the new current standard control system can ensure the consistency of the train's traction instructions, braking instructions, and vehicle control levels, and avoid major changes in the traction instructions, braking instructions, and vehicle control levels, which may cause safety hazards, in this example, the current standard control system will send the control parameters of the train to the background standard control system, so that the background standard control system can obtain the status of the train based on the control parameters, and the control parameters include but are not limited to traction instructions, braking instructions, and vehicle control levels.
[0056] Specifically, the current standard control system periodically (the specific period can be flexibly set by relevant personnel according to actual needs; in some examples, the current standard control system can also collect control parameters of the control train in real time) collects control parameters of the control train, and sends the control parameters to the background standard control system, so that the background standard control system obtains the status of the train based on the control parameters, so that the current standard control system and the background standard control system periodically interact with the traction instructions, braking instructions, and vehicle control level information of the current standard control system. During the switching process, the current standard control system and the background standard control system ensure that the traction instructions, braking instructions, and vehicle control levels are consistent. On the basis of the above-mentioned insertion of the target driving speed, traction instructions, braking instructions, and vehicle control level, smooth switching between the current standard control system and the background standard control system is achieved.
[0057] According to the technical solution provided in the embodiment of the present application, the control parameters of the train controlled by the current standard control system are periodically collected; the control parameters are sent to the background standard control system, so that the background standard control system obtains the status of the train based on the control parameters, and the current standard control system and the background standard control system periodically interact with the traction instructions, braking instructions, vehicle control level information, etc. of the current standard control system to control the vehicle. During the switching process, the current standard control system and the background standard control system ensure that the traction instructions, braking instructions, and vehicle control levels are consistent. On the basis of the above-mentioned insertion of the target driving speed, traction instructions, braking instructions, and vehicle control level, smooth switching between the current standard control system and the background standard control system is achieved.
[0058] In some examples, the two standard control systems are a CBTC standard control system and a CTCS2 standard control system, such as Figure 6 As shown, in response to the received system switching message, before obtaining the system switching point of the train on the current travel route, the method also includes:
[0059] S601. Receive a current standard control system determination instruction, and use the CBTC standard control system as the current standard control system according to the current standard control system determination instruction. The CBTC standard control system sends a current standard control system determination message to the CTCS2 standard control system, so that the CTCS2 standard control system serves as the background standard control system.
[0060] Specifically, Figure 7 As shown, when the train starts, the CTCS2 control system and the CBTC control system are powered on and started. The CTCS2 control system displays the system selection interface through the corresponding interactive interface, and the CBTC control system also displays the system selection interface through the corresponding interactive interface.
[0061] The user (driver) selects the corresponding standard control system according to the standard of the current route of the train; if the standard of the current route is the CTCS2 standard route, the user selects the CTCS2 standard control system as the current standard control system in the interactive interface of the CTCS2 standard control system (it can also be input through an additional standard selection knob), and the CTCS2 standard control system will send a current standard control system confirmation message to the CBTC standard control system, so that the CBTC standard control system serves as the background standard control system. If the standard of the current route is the CBTC standard route, the user selects the CBTC standard control system as the current standard control system in the interactive interface of the CBTC standard control system to control the train; and at this time, the CBTC standard control system will send a current standard control system confirmation message to the CTCS2 standard control system, so that the CTCS2 standard control system serves as the background standard control system and does not control the train.
[0062] In some examples, the current standard control system determination instruction may also be issued by ground equipment on the current driving route.
[0063] According to the technical solution provided in the embodiment of the present application, a current standard control system determination instruction is received, and the CBTC standard control system is used as the current standard control system according to the current standard control system determination instruction, and the CBTC standard control system sends a current standard control system determination message to the CTCS2 standard control system, so that the CTCS2 standard control system is used as the background standard control system, and the current standard control system and the background standard control system are determined from different standard control systems when the train starts, so that the current standard control system determined when the train starts can safely control the train to travel on the current route.
[0064] In some examples, such as Figure 8 As shown, in response to the received mode switching message, obtaining the mode switching point of the train on the current route includes:
[0065] S801. During the running of the train, a mode switching message transmitted by the CBTC ground equipment is received;
[0066] S802: In response to the system switching message transmitted by the CBTC ground equipment, obtain the system switching point of the train on the current travel route.
[0067] This example takes the case where the train is currently traveling on a CTCS2 standard route. During the travel of the train, if the train is about to enter a CBTC standard route, the ground equipment on the CBTC standard route will transmit a standard switching message to the train, so that both the CTCS2 standard control system and the CBTC standard control system can receive the standard switching message. The CTCS2 standard control system and / or the CBTC standard control system respond to the standard switching message transmitted by the CBTC ground equipment to obtain the standard switching point of the train on the current route.
[0068] Similarly, taking the case where the train is currently traveling on a CBTC standard route as an example, during the train's travel, if the train is about to enter a CTCS2 standard route, the ground equipment on the CTCS2 standard route will transmit a standard switching message to the train, so that both the CTCS2 standard control system and the CBTC standard control system can receive the standard switching message. The CTCS2 standard control system and / or the CBTC standard control system respond to the standard switching message transmitted by the CTCS2 ground equipment to obtain the standard switching point of the train on the current route.
[0069] In some examples, the above-mentioned mode switching message may also be sent by a user (train driver).
[0070] According to the technical solution provided in the embodiment of the present application, during the travel of the train, a mode switching message transmitted by the CBTC ground equipment is received; in response to the mode switching message transmitted by the CBTC ground equipment, the mode switching point of the train on the current travel route is obtained, so that both the CTCS2 mode control system and the CBTC mode control system can receive the mode switching message, and the CTCS2 mode control system and / or the CBTC mode control system can respond to the mode switching message transmitted by the CBTC ground equipment in a timely manner to obtain the mode switching point of the train on the current travel route.
[0071] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.
[0072] The following is an embodiment of the device of the present application, which can be used to execute the embodiment of the method of the present application. For details not disclosed in the embodiment of the device of the present application, please refer to the embodiment of the method of the present application.
[0073] This embodiment also provides a train control system switching device, such as Fig. 9 As shown, the device is deployed on a train, and two independent interfaces are provided on the train. Each independent interface is connected to a standard control system. When the train is running, the standard control system that controls the train is the current standard control system, and the other standard control system is the background standard control system. The device includes:
