Description

Technical Field

[0001] This invention relates to the field of automatic control technology for trains, and more particularly to a control method for a train lighting system, a train control and management system, and a train. Background Technology

[0002] With the increasing sophistication of fully automated driving technology in urban rail transit, more and more cities are beginning to build fully automated rail transit lines. In fully automated rail transit vehicles, the driver does not participate in the real-time control of the vehicle; the automatic driving is controlled by the train's automatic control system or remotely controlled by the vehicle dispatch center.

[0003] As one of the basic systems of a train, the onboard lighting system is traditionally controlled by the driver in rail transit by operating buttons in the driver's cab. However, fully automated trains do not have drivers, therefore, a control method for the lighting system of automated trains is needed to achieve automatic control of the lighting system of driverless trains. Summary of the Invention

[0004] The main objective of this invention is to provide a control method for a train lighting system, a train control and management system, and a train, so as to realize the automatic control of the lighting system of an unmanned train.

[0005] In a first aspect, the present invention provides a control method for a train lighting system, comprising: acquiring control commands for the train lighting system; when the number of control commands acquired within a first preset time period is two or more, selecting the control command with the highest priority from the two or more control commands according to a preset method, and using the control command with the highest priority as the target control command; and sending the target control command to the train lighting system to control the opening and closing of the train lighting system.

[0006] In one embodiment, the highest priority control instruction is selected from two or more control instructions according to a preset method, including: selecting the control instruction acquired earliest or latest within a first preset time period as the highest priority control instruction; or selecting the control instruction acquired at a specified time as the highest priority control instruction.

[0007] In one embodiment, before selecting the highest priority control instruction from two or more control instructions according to a preset method, the method further includes: obtaining the source of each control instruction; selecting the highest priority control instruction from two or more control instructions according to a preset method, including: based on the preset priority relationship between different sources of control instructions, selecting the control instruction from the highest priority source as the highest priority control instruction.

[0008] In one embodiment, the sources of control commands include: on-board human-machine interface, on-board cloud platform, train automatic control system, and train control and management system; the preset priority relationship between different sources of control commands includes: the priority of on-board human-machine interface, on-board cloud platform, train automatic control system, and train control and management system decreases in that order.

[0009] In one embodiment, the control commands of the train control and management system are generated according to the following steps: obtaining the current operating condition of the train; based on the preset correspondence between the train operating condition and the on / off state of the train lighting system, generating control commands for the train lighting system according to the current operating condition of the train.

[0010] In one embodiment, the highest priority control command includes a test command for the train lighting system, which includes: when the current state of the train lighting system is on, controlling the train lighting system to turn off and then on within a second preset time period; and when the current state of the train lighting system is off, controlling the train lighting system to turn on and then off within a third preset time period.

[0011] In one embodiment, before using the highest priority control command as the target control command, the method further includes: obtaining the current state of the train lighting system; using the highest priority control command as the target control command includes: when the highest priority control command is a test command, determining the target control command based on the current state of the train lighting system; when the highest priority control command is not a test command, determining whether the state of the train lighting system indicated by the highest priority control command is consistent with the current state of the train lighting system; when the state of the train lighting system indicated by the highest priority control command is inconsistent with the current state of the train lighting system, using the highest priority control command as the target control command.

[0012] In one embodiment, after sending the target control command to the train lighting system, the method further includes: receiving a feedback signal from the train lighting system, the feedback signal indicating the current state of the train lighting system; matching the feedback signal with the target control command, and determining that the train lighting system has malfunctioned when the feedback signal fails to match the target control command.

[0013] Secondly, the present invention provides a computing device, including a processor and a memory, wherein the memory stores a computer program, and when the computer program is executed by the processor, it implements the steps of the control method for the train lighting system as described above.

[0014] Thirdly, the present invention provides a train control and management system, including the computing device described above.

[0017] Based on the application scenario of fully automated trains, the method of this invention can orderly determine the unique control command when multiple control commands for the train lighting system are received, thereby successfully realizing orderly automatic control of the train lighting system, saving manpower and labor costs, and reducing the technical requirements for drivers. Attached Figure Description

[0018] The accompanying drawings, which form part of this application, are used to provide a further understanding of the invention. The illustrative embodiments of the invention and their descriptions are used to explain the invention and do not constitute an undue limitation of the invention. In the drawings:

[0019] Figure 1 This is a flowchart of a control method for a train lighting system according to an exemplary embodiment of this application;

[0020] Figure 2 This is a schematic diagram of the signal flow of a control method for a train lighting system according to a specific embodiment of this application. Detailed Implementation

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] This embodiment provides a control method for a train lighting system. Figure 1 This is a flowchart of a control method for a train lighting system according to an exemplary embodiment of this application. Figure 1 As shown, the method in this embodiment includes:

[0024] S100: Obtain control commands for the train lighting system.

[0025] S200: When the number of control commands acquired within the first preset time period is two or more, the control command with the highest priority is selected from the two or more control commands according to the preset method, and the control command with the highest priority is used as the target control command.

[0026] S300: Sends target control commands to the train lighting system to control the turning the train lighting system on and off.

[0027] Through the above steps, when more than two control commands for the train lighting system are received within the first preset time period, the control command with the highest priority is selected as the target control command, and the train lighting system is controlled by the target control command. When there are many control commands for the train lighting system, orderly automatic control of the train lighting system is achieved through automatic selection of control commands.

[0028] In the above steps, the first preset duration can be set as needed, such as 1 minute, 2 minutes, or 0 minutes, i.e., the same moment. The preset method can be flexibly set as needed. For example, according to the preset method, the control instruction with the highest priority is selected from two or more control instructions. This can include: taking the control instruction obtained earliest or latest within the first preset duration as the control instruction with the highest priority; or taking the control instruction obtained at a specified moment as the control instruction with the highest priority. The specific method is not limited here, as long as one control instruction can be determined from multiple control instructions.

[0029] In one example, before selecting the highest-priority control instruction from two or more control instructions according to a preset method, the process may further include: obtaining the source of each control instruction. Correspondingly, selecting the highest-priority control instruction from two or more control instructions according to a preset method may include: based on a preset priority relationship between different sources of control instructions, selecting the control instruction from the highest-priority source as the highest-priority control instruction.

[0030] The sources of control commands can include: the onboard human-machine interface, the onboard cloud platform, the train automatic control system, and the train control and management system. Correspondingly, the preset priority relationship between the different sources of control commands can be: the priority decreases sequentially from the onboard human-machine interface, the onboard cloud platform, the train automatic control system, to the train control and management system.

[0031] Of course, the sources of control commands are not limited to those listed above. Those skilled in the art can redetermine the possible sources of control commands as needed and preset the priority relationship between the various possible sources of control commands so as to be able to determine a unique control command to control the train lighting system when multiple control commands are received.

[0032] The control commands of the train control and management system can be generated according to the following steps: obtain the current operating condition of the train; based on the preset correspondence between the train operating condition and the on / off state of the train lighting system, generate control commands for the train lighting system according to the current operating condition of the train.

[0033] The current operating condition of the train can be determined by other information processing equipment based on specific information and according to certain logic. For example, for a fully automated driverless train, the train automatic control system can determine the current operating condition of the train based on signals detected from specific signal generating devices installed on the rail transit line, and send the determination result to the controller executing the method of this embodiment. This controller can be, for example, a train control and management system. The train control and management system then determines the proper state of the train lighting system based on the received current operating condition of the train, and then generates control commands for the train lighting system. For example, if the train control and management system determines that the train lighting system should be in an off state based on the current operating condition of the train, it generates a shutdown command for the train lighting system; if it determines that the train lighting system should be in an on state, it generates an on command for the train lighting system.

[0034] The highest priority control command may include: a test command for the train lighting system. The test command may include: when the current state of the train lighting system is on, controlling the train lighting system to turn off and then on within a second preset time period; when the current state of the train lighting system is off, controlling the train lighting system to turn on and then off within a third preset time period.

[0035] The test command for the train lighting system is the self-check command performed on the lighting system after the train is initially powered on. It requires the lighting system to perform an on / off action once within a preset time period. Of course, the number of on / off actions can be flexibly set; no specific limit is placed here. The test command for the train lighting system can be generated by the train's automatic control system, or it can be generated by other equipment according to settings.

[0036] The first, second, and third preset durations can be set according to their respective application scenarios. The second and third preset durations can be the same or different, and there is no specific limitation.

[0037] Before using the highest priority control command as the target control command, the process may further include: obtaining the current state of the train lighting system. Using the highest priority control command as the target control command may include: when the highest priority control command is a test command, determining the target control command based on the current state of the train lighting system; when the highest priority control command is not a test command, determining whether the state of the train lighting system indicated by the highest priority control command is consistent with the current state of the train lighting system; if the state of the train lighting system indicated by the highest priority control command is inconsistent with the current state of the train lighting system, using the highest priority control command as the target control command.

[0038] After sending the target control command to the train lighting system, the system may further include: receiving a feedback signal from the train lighting system, the feedback signal indicating the current state of the train lighting system; matching the feedback signal with the target control command; and determining that the train lighting system has malfunctioned when the feedback signal fails to match the target control command.

[0039] Based on the application scenario of fully automated driving trains, this embodiment can systematically identify a unique control command from multiple control commands received for the train lighting system, thereby successfully achieving orderly automatic control of the train lighting system, saving manpower and labor costs, and reducing the technical requirements for drivers. Furthermore, this embodiment can determine the control command based on the train's operating conditions and preset priority levels for each possible source of the control command. Therefore, when multiple control commands are received, the highest priority control command can be determined based on the control priority, achieving automatic and orderly control of the train lighting system.

[0040] Example 2

[0041] Fully automated driverless trains operate without a driver in real time, relying on control commands from various parties to automatically control the train's lighting system.

[0042] This embodiment proposes a control method for a train lighting system, which is applied to a fully automated driverless train to achieve automatic control of the train lighting system.

[0043] In fully automated driverless trains, the train lighting system can be directly controlled by the TCMS (Train Control and Management System). For example, when the TCMS outputs a "lighting on / off" signal, if the output is 1 (high level), the lighting is turned off; if the output is 0 (low level), the lighting is turned on (the default value is 0 when the train is initially powered on).

[0044] Since the train is first powered on, the TCMS can default to continuously outputting a 0 (low level) "lighting on / off" signal, i.e., outputting a "lighting on command" by default. If no command is input, the lighting will remain on by default. When receiving "lighting on command" or "lighting off command" from multiple sources, the TCMS determines the target control command to control the train's lighting system.

[0045] Combination Figure 2 The sources of control commands for train lighting systems can include the following four types:

[0046] (1) The train lighting system is turned on and off by using the soft button of the on-board HMI (Human Machine Interface) (e.g., level signal: 1 = off, 0 = on).

[0047] When the TCMS receives the rising edge of the "Lighting Control On / Off" signal output by the HMI, it immediately executes the "Lighting Off" command. If it detects the falling edge of the "Lighting Control On / Off" signal, it immediately executes the "Lighting On" command.

[0048] (2) The ATC (Automatic Train Control) issues test commands to control the opening and closing of the train lighting system.

[0049] The ATC outputs a lighting test command, and the TCMS can output a "lighting on" command or a "lighting off" command based on the current status of the train's lighting system. For example, if the train's lighting system is currently off, the TCMS will first output a "lighting on" command after receiving the lighting test command, and then output a "lighting off" command to restore the original state. If the train's lighting system is currently on, the TCMS will first output a "lighting off" command after receiving the lighting test command, and then output a "lighting on" command to restore the original state.

[0050] (3) In Fully Automatic Model (FAM), the ATC can detect the current operating condition of the train, and the TCMS can generate control commands to start or stop the lighting based on the current operating condition. The on / off states of the train lighting system corresponding to various exemplary operating conditions are shown in Table 1 below:

[0051] Table 1. On / off status of train lighting systems under various operating conditions in FAM mode.

[0052] Serial Number Scene Name Lighting switch status 1 Power on and standby open 2 stand by close 3 On-site operation close 4 Enter mainline service open 5 Mainline service discontinued close 6 cleaning open 7 Hard wire maintenance conditions open

[0053] (4) The vehicle dispatching center transmits control commands to the TCMS through the onboard OCS (Onboard Cloud System, used for vehicle-to-ground data transmission, monitoring train status and remotely controlling vehicles in the control center to achieve intelligent operation and maintenance) system. The dispatching center can remotely control the train lighting system to turn on or off (via pulse signals). In FAM mode, for example, when the train has finished running and is parked in the depot, the TCMS can also receive sleep commands through the control commands received from the OCS system.

[0054] For example, when the TCMS receives multiple control commands within one minute, the last control command received can be used to control the train lighting system. The sources of multiple train lighting systems can also be prioritized. For example, the HMI can be set to have the highest priority, followed by the OCS, ATC, and TCMS. Of course, if control commands from the above four sources are received at the same time, the control command for the train lighting system can be determined according to the priority relationship.

[0055] After the TCMS determines the target control command system, it can send the control command to the IOM (Input Output Module, used to acquire digital and analog signals from the vehicle) chassis via the MVB (Multifunction Vehicle Bus). The IOM chassis then sends the control command to the train lighting system via hardwired connections. Subsequently, it obtains the device status of the train lighting system to determine the execution status of the train lighting system and feeds back the execution status of the train lighting system to the TCMS. Finally, the TCMS feeds back the execution status to the source of the control command.

[0056] This embodiment, based on the application scenarios of fully automated vehicles, divides the control of the onboard lighting system into several different scenarios, each allowing for the control of turning the lighting system on or off. When multiple control commands for the train lighting system are received, a unique control command can be identified in an orderly manner, thus successfully achieving orderly automatic control of the train lighting system. In particular, this embodiment can determine the control command for the train lighting system based on the train's operating conditions, which is beneficial for improving the automation level of fully automated driverless trains.
