Description

Technical Field

[0001] The present application relates to the field of train control technology, and in particular to a train control system, method, storage medium and electronic equipment. Background Art

[0002] The urban rail is a rail transit system that connects cities in the metropolitan area and provides large-capacity, bus-like transportation services for commuter passengers. The urban rail with "bus-like" characteristics has the characteristics of short departure intervals, high speeds, and large station spacing. Currently, the urban rail can be realized through the CTCS-2 (Chinese Train Control System-2, C2) + ATO system. However, due to the need for bus-like operations, trains on the urban rail need to interface with the platform screen door (PSD) system to meet the transfer needs of passengers.

[0003] For the C2+ATO system, when the train leaves the station, the on-board equipment controls the train doors to close and sends a door closing command to the platform door system to control the platform doors to close. At the same time, the on-board equipment controls the train to depart from the station.

[0004] When the train leaves the station, after the platform door system receives the door closing command sent by the onboard equipment, due to some reasons, such as relay failure, interface communication interruption, etc., the platform door fails to close, and the platform door is still open. However, after the onboard equipment detects that all the doors of the train are closed, the onboard equipment will issue a departure command to control the train to leave the platform. At this time, the platform door is open and the train moves, which may cause passengers on the platform to be hit by the moving train. Therefore, the existing train control method will bring safety risks to passengers on the platform. Summary of the invention

[0035] It should also be understood that the term "if" may be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting." Similarly, the phrase "if it is determined that ..." or "if [a stated condition or event] is detected" may be interpreted as "upon determining that ..." or "in response to determining that ..." or "upon detecting [a stated condition or event]" or "in response to detecting [a stated condition or event]," depending on the context.

[0036] The implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0037] For example, see Figure 1 , Figure 1 A schematic diagram of a train control system to which the technical solution provided by the present application is applicable is shown. The train control system 100 may include a computing device 110, a train control device 120 and an onboard device 130. The computing device 110, the train control device 120 and the onboard device 130 are connected via network communication.

[0038] A platform door control system for controlling multiple platform doors within the platform section is deployed on the computing device 110. In an embodiment of the present application, the computing device 110 is used to send the status of multiple platform doors within the platform section to the train control device 120, and the status of the platform doors includes open and closed. For example, when the computing device 110 detects that the minimum front end of the train enters the starting point of the platform section, the status of multiple platform doors within the platform section is sent to the train control device 120. When the status of multiple platform doors within the platform section are all closed, a platform door closing command is sent to the train control device 120. When the status of any platform door within the platform section is open, a platform door opening command is sent to the train control device 120.

[0039] The computing device 110 is also used to receive a door opening instruction or a door closing instruction for controlling the status of the platform door sent by the train control device 120. For example, when the computing device 110 receives a door closing instruction sent by the train control device 120, it indicates that the passengers on the train have completed boarding and alighting, and the train can continue to run. At this time, the computing device 110 controls the closing of multiple platform doors in the platform section according to the door closing instruction sent by the train control device 120. When the computing device 110 receives a door opening instruction sent by the train control device 120, it indicates that the train has entered the platform section and the train doors have completed the marked stop with the platform doors. At this time, the computing device 110 controls the opening of multiple platform doors in the platform section according to the door opening instruction sent by the train control device 120.

[0040] The train control equipment 120 (Train Control Center, TCC) is a train control safety equipment installed in each station (platform section) or relay station, and is connected to the track circuit, computer interlocking, temporary speed limit server, other station train control equipment, balise ground electronic unit (Lineside Electronic Unit, LEU), train dispatching centralized system (Centralized traffic control, CTC) and other systems through signals to realize functions such as track circuit, active balise, section direction and block control. The train control equipment generates relevant empty car information such as route and temporary speed limit according to dispatching commands, route status, line parameters, etc., and transmits it to the train dynamically through active balise and track circuit, thereby realizing dynamic control of train operation.

[0041] In the embodiment of the present application, the train control device 120 is used to obtain the door status of the train, the status of the door protection brake of the train, and the status of multiple platform doors in the platform section from the on-board device 130 when receiving the door closing command sent by the on-board device 130 of the train, and obtain the status of multiple platform doors in the platform section from the computing device 110. The train control device 120 controls the running state of the train according to the door status of the train, the status of the door protection brake of the train, and the status of multiple platform doors in the platform section. For example, when the door status of the train is closed and the status of the door protection brake of the train is relieved, the train control device 120 sends a departure command to the on-board device 130 to control the running state of the train to the driving state. When the door status of the train is closed, the status of the door protection brake of the train is non-relaxed, and the status of multiple platform doors in the platform section are all closed, the train control device 120 sends a departure command to the on-board device 130 to adjust the status of the door protection brake of the train to be relieved, and control the running state of the train to be the driving state. When the door status of the train is open or the status of any platform door in the platform section is open, the train control device 120 does not send a departure command to the on-board device 130 to control the running status of the train to a stopped state.

[0042] In the implementation mode of the present application, the train control device 120 is also used to obtain the position information of the train from the on-board device 130. When the smallest front end of the train enters the starting point of the platform section, the status of multiple platform doors in the platform section is obtained from the computing device 110. When the status of multiple platform doors in the platform section are all closed, the train control device 120 sends an HU code to the on-board device 130. After the on-board device 130 completes the parking with the multiple platform doors according to the HU code, the train control device 120 sends a door opening command to the on-board device 130 and the computing device 110 to open the doors of the train and the multiple platform doors in the platform section, and control the state of the door protection brake of the train to not be relieved, so as to avoid the problem of the train running with the doors open or the multiple platform doors in the platform section open, causing passengers to be injured when transferring.

[0043] The onboard device 130 may be an Automatic Train Protection (ATP) system. The ATP system is used to prevent trains from speeding, colliding, and other dangerous situations that may occur when the train is running. The system transmits the maximum safe speed limit signal to the train through the track, and continuously compares the actual speed of the train with the maximum safe speed. If the actual speed of the train exceeds the maximum safe speed, the system will instruct the train to perform emergency braking to prevent the train from speeding. At the same time, the system will ensure that when the train is in emergency braking, there is enough unoccupied road ahead for the train to stop without colliding.

[0044] In the implementation manner of the present application, the on-board device 130 is used to determine the state of the door protection brake of the train according to the code sequence sent by the train control device 120 after sending the door closing command to the train control device 120. For example, when the code sequence sent by the train control device 120 is the HU code, the state of the door protection brake of the train is controlled to be not relieved. When the code sequence sent by the train control device 120 is not the HU code, the state of the door protection brake of the train is controlled to be relieved.

[0045] In the implementation manner of the present application, the train control system 100 further includes a server 140 , and the server 1540 is connected to the computing device 110 , the train control device 120 , and the onboard device 130 via a network communication.

[0046] Server 140 may be a Temporary Speed ​​Restriction Server (TSRS). The Temporary Speed ​​Restriction Server is a control system based on a signal failure safety computer. It can realize the centralized management of temporary speed limit commands for the entire line, aiming to ensure the safety of the speed limit setting of the train control and the smooth implementation of the speed limit plan. That is, the Temporary Speed ​​Limit Server is used to generate speed limit information for the train when the line where the train is expected to run is inoperable (for example: construction, disaster, equipment failure, etc.), and control the train to run according to the speed limit information, that is, control the train to run at the speed indicated by the speed limit information within the range indicated by the speed limit information.

[0047] In an embodiment of the present application, the temporary speed limit server is used to receive status information of multiple platform doors in the platform section sent by the train control device 120, generate speed limit information for the train based on the received status information of the multiple platform doors in the platform section, and send the status information of the multiple platform doors in the platform section and the generated speed limit information to the on-board device 130 of the train to control the operation of the train.

[0048] The temporary speed limit server is also used to receive door opening instructions or door closing instructions sent by the on-board device 130 for controlling the status of multiple platform doors in the platform section, and send the door opening instructions or door closing instructions to the computing device 110 through the train control device 120 to control the status of multiple platform doors in the platform section according to the door opening instructions or door closing instructions.

[0049] In order to ensure the correctness of the code sequence sent by the train control device to the on-board device 130 through the temporary speed limit server, that is, the code sequence sent by the train control device to the on-board device through the temporary speed limit server will not be tampered with. And the correctness of the status of multiple platform doors in the platform section sent by the computing device to the on-board device through the train control device and the temporary speed limit server. The train control device 120 and server 140 of this application are devices with the highest safety integrity level (Safety Integrity Level 4, SIL4). SIL4 refers to the level of systems or equipment with very high safety requirements. It requires the system to have extremely high reliability and integrity, be able to operate and respond correctly in all situations, avoid any errors or failures that may cause accidents or injuries, and play a very important role in personal safety and environmental protection. And when the temporary speed limit server communicates with the train control device or the on-board device, it is necessary to adopt safety-related protocols to further ensure the correctness of the status of multiple platform doors in the platform section transmitted from the train control device to the on-board device.

[0050] Optionally, the computing device 110, train control device 120, on-board device 130 or server 140 of the present application may be an electronic device with data processing capabilities, or a functional module in the electronic device, without limitation.

[0065] The train control system and application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art can appreciate that with the evolution of the train control system and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0066] Next, the train control method is described in detail with reference to the accompanying drawings. Figure 3 A flow chart of a train control method provided in this application. The method is applied to Figure 1 The train control device in the train control system shown specifically includes the following steps:

[0067] Step 310: When a door closing command is received from the onboard equipment of the train, the status of the train door, the status of the train door protection brake, and the status of multiple platform doors in the platform section are obtained.

[0068] In one embodiment, when the train approaches the target station (i.e., the target platform section), the train control device obtains the position information of the train. When the train control device determines the starting point of the minimum front end of the train entering the platform section according to the obtained train position information, in order to ensure the safe operation of the train, that is, to avoid the problem that there are unclosed platform doors in the platform section when the train enters the station, thereby causing safety risks for passengers on the platform, the train control device obtains the status of multiple platform doors in the platform section. When the status of multiple platform doors in the platform section are all closed, the passengers on the platform will not enter the track of the train through the unclosed platform doors, and then collide with the train entering the platform section. Therefore, the train control device sends the HU code to the on-board device. At this time, the display of the on-board device shows a half yellow and half red light. The HU code indicates that the ground signal machine approaching the train has not opened the access. In the embodiment of the present application, the on-board device receives the HU code sent by the train control device, which means that it can run to the end of the platform section, that is, the train can enter the platform section. However, since the next ground signal that the train is approaching has not opened the way, the train cannot enter the next driving section, that is, the smallest front end of the train cannot drive out of the end of the platform section. After receiving the HU code sent by the train control device, the on-board equipment of the train controls the alignment of the door with the platform door and stops the train. At this time, the train has stopped steadily, and the doors of the train are aligned with the platform doors, and the doors of the train and the platform doors are both in a closed state. There is no safety risk, and the doors and platform doors can be opened to allow passengers on the train and on the platform to get on and off. Therefore, the train control device sends a door opening command to the on-board equipment and multiple platform doors.

[0069] At the same time, it is also necessary to control the state of the train's door protection brake to not be released. When the train's door protection brake is not released, the train cannot run and can only be in a stopped state. Therefore, it can be further ensured that when the train's doors and platform doors in the platform section are open, the train will not run, thereby ensuring the safety of passengers getting on and off the train at this time.

[0070] like Figure 4 As shown in the figure, when the status of multiple platform doors in the platform section are all closed and the smallest front end of the train passes the starting point of the platform section, the train control equipment continuously sends HU codes to the on-board equipment. After the on-board equipment completes the alignment of the train and multiple platform doors, it sends a door opening command to the on-board equipment and multiple platform doors, and controls the status of the train's door protection brake to not be released.

[0071] When the passengers on the train and the passengers on the platform have finished getting on and off the train, the train doors need to be closed, and the platform doors within the platform section also need to be closed, and then the train continues to run.

[0072] In the prior art, after the passengers have completed the transfer, the train's onboard equipment directly adjusts the train's door protection brake state to relief after all the train doors are closed. In the prior art, when the train's door protection brake state is relief, the train can run. At this time, although the train's onboard equipment sends a door closing command to the train control device through the temporary speed limit server to control the closure of multiple platform doors in the platform section. However, due to relay failure, interface communication interruption and other reasons, one or more platform doors in the platform section may not be closed due to abnormalities. Then at this time, if there are unclosed platform doors in the platform section, running the train will bring safety risks to passengers on the platform.

[0073] Therefore, in the embodiment of the present application, when the train control device receives the door closing command sent by the onboard device of the train, the state of the train door, the state of the train door protection brake, and the state of multiple platform doors in the platform section are obtained. The running state of the train is controlled according to the state of the train door, the state of the train door protection brake, and the state of multiple platform doors in the platform section. This avoids the problem in the prior art that the running state of the train is controlled only according to the state of the train door and the state of the train door protection brake, which causes safety risks to passengers on the platform.

[0074] Step 320: Control the running state of the train according to the state of the train doors, the state of the door protection brakes of the train, and the states of multiple platform doors in the platform section.

[0075] In one embodiment, as long as the train control device detects that there are unclosed platform doors in the platform section, it will continuously send HU codes to the on-board device, and the on-board device controls the state of the train's door protection brake according to the code sequence sent by the train control device. When the code sequence sent by the train control device is the HU code, the state of the train's door protection brake is controlled to be unrelieved. When the code sequence sent by the train control device is not the HU code, the state of the train's door protection brake is controlled to be relieved. Therefore, when the train's door state is closed and the train's door protection brake state is relieved, as Figure 5 As shown, the doors of the train and multiple platform doors in the platform section are all in a closed state, which will not cause safety risks to the passengers on the train and on the platform. Therefore, the train control device sends a departure command to the on-board device to control the train's operating state to the driving state.

[0076] In another embodiment, when the door status of the train is open or the status of any platform door in the platform section is open, no departure command is sent to the on-board equipment to control the running status of the train to a stopped state.

[0077] like Figure 6 As shown, after the passengers on the train and the passengers on the platform have finished getting on and off the train, the on-board equipment of the train sends a door closing command to the train control equipment. At this time, all the doors of the train are closed. However, the platform doors on the platform section are not closed due to relay failure, interface communication interruption and other reasons. At this time, the train control equipment detects that there are unclosed platform doors in the platform section, and continuously sends HU codes to the on-board equipment. After receiving the HU code sent by the train control equipment, the on-board equipment still controls the state of the train's door protection brake to non-relaxed. At this time, the train's door state is closed, the train's door protection brake state is non-relaxed, and there are unclosed platform doors in the platform section. The train control equipment does not send a departure command to the on-board equipment to control the train's running state to the parking state. This prevents the train from running with open platform doors, posing a safety risk to passengers on the platform.

[0078] In another embodiment, when the train enters the platform section and stops to open the door, the train driver finds that the train door is not aligned with the platform door, or needs to move the train for other reasons, and needs to close the train door and the platform door in the platform section. If the on-board equipment can only adjust the state of the train door protection brake to relief according to the non-HU code sent by the train control equipment, then the train cannot move at this time, which will affect the train's availability and driving efficiency.

[0079] Therefore, in the implementation mode of the present application, the train control device can control the running state of the train only according to the state of the train doors and the state of multiple platform doors in the platform section. Since the doors of the train and the platform doors in the platform section are all in a closed state, the movement of the train will not cause safety risks to the passengers on the train and the passengers on the platform. Therefore, when the door state of the train is closed, the state of the door protection brake of the train is non-relieved, and the state of multiple platform doors in the platform section are all closed, the train control device can send a departure command to the on-board device to adjust the state of the door protection brake of the train to be relieved, and control the running state of the train to be the driving state. Then, on the basis of ensuring the safety of the passengers on the train and the passengers on the platform, the need to move the train due to the misalignment of the train doors and platform doors or other reasons is met.

[0080] Figure 7 A flow chart of another train control method provided in this application. The method is applied to Figure 1 The on-board equipment in the train control system shown in the figure specifically includes the following steps:

[0081] Step 710: After sending a door closing command to the train control device, determine the state of the train door protection brake according to the code sequence sent by the train control device.

[0082] The code sequence sent by the train control device to the onboard device through the temporary speed limit server includes but is not limited to: HU code, UU code, UUS code, L5 code, etc. The UU code indicates that the ground signal machine approaching the train has opened the route through the lateral position of the turnout. When the onboard device receives the UU code sent by the train control device, a double half-yellow light is displayed on the display of the onboard device. At this time, the train is allowed to pass the approaching ground signal machine at a speed not higher than 45km / h. The UUS code indicates that the ground signal machine approaching the train has opened the route through the lateral position of turnout No. 18 and above, and the route allows the train to pass the approaching ground signal machine at a speed not lower than 80km / h. When the onboard device receives the UUS code sent by the train control device, a double half-yellow flash is displayed on the display of the onboard device. The L5 code indicates that there are at least 7 free block sections ahead of the train. When the onboard device receives the L5 code sent by the train control device, a green light with the word "5" is displayed on the display of the onboard device.

[0083] The code sequence provided above that the train control device sends to the on-board device through the temporary speed limit server is only used as an example to explain the present application. The present application does not make any specific limitation on the code sequence that the train control device sends to the on-board device.

[0084] When the code sequence sent by the train control device is HU code, it means that the ground signal of the train approaching has not opened the approach route, then the state of the door protection brake of the control train is not released. When the code sequence sent by the train control device is not HU code, the state of the door protection brake of the control train is released.

[0085] In summary, the present application can avoid the problem in the prior art that when there is a platform door that is not closed due to an abnormality in the platform section, the train control equipment only controls the running status of the train according to the status of the train door, causing safety risks to the passengers on the platform, thereby improving the safety of the train.
