[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Combine the following Figure 1-Figure 6 The present invention describes a train safety operation control method and device.

[0026] Figure 1 FIG. 1 is one of the flow charts of the train safety operation control method provided by the present invention, such as Figure 1 As shown, the method comprises the following steps: Step 110: When the intelligent train ITE system of the train identifies the existence of an obstacle on the target line, it generates obstacle information and sends the obstacle information to the onboard controller VOBC; wherein the obstacle information includes alarm information and obstacle location information.

[0027] In this step, the Intelligent Train Eye (ITE) system integrates multiple sensors such as radar and cameras to achieve real-time monitoring and information collection of the line ahead of the train.

[0028] Specifically, when the ITE system detects an obstacle, it will immediately trigger the alarm mechanism and generate alarm information. This information usually includes the type of obstacle (such as static obstacles, dynamic obstacles, etc.), size and potential threat level to the train operation. In addition, the ITE system will also accurately measure and record the location information of the obstacle, including the relative distance of the obstacle from the train, direction (such as front, side, etc.) and the specific location coordinates of the obstacle on the railway line. The ITE subsystem can realize all-round perception and accurate detection of the surrounding environment of the train, thereby improving the safety and reliability of train operation.

[0029] In this embodiment, after the obstacle information is generated, the ITE system will send this information to the vehicle on board controller (Vehicle On Board Controller or Vehicle On Board Computer, VOBC) through a dedicated communication link for subsequent processing; wherein, the VOBC is used to receive and process information from various sensors on the train to achieve precise control of the train operation.

[0030] Step 120: Brake the train according to the alarm information based on VOBC, and forward the obstacle position information to the automatic train monitoring system ATS through the automatic train protection system ATP.

[0031] In this step, the alarm information may be a command signal, and VOBC may parse the alarm level or specific obstacle type from the alarm information.

[0032] In this embodiment, after receiving the obstacle information, the VOBC onboard controller will evaluate the impact of the obstacle on the train operation and take corresponding control measures based on the type, size and location information of the obstacle.

[0033] Specifically, after VOBC determines the current alarm level from the alarm information, it determines the current braking strategy based on the preset alarm level and braking strategy association table to achieve emergency braking of the train, so that the train stops immediately to avoid a collision accident; the ATP system can automatically calculate and execute braking measures according to the location of the obstacle and the current operating status of the train, avoiding errors and delays caused by human operations.

[0034] In this embodiment, the ATP (Automatic Train Protection, ATP) system forwards the obstacle location information to the ATS (Automatic Train Supervision, automatic train monitoring system) through vehicle-ground communication; for example, the ATP system can encapsulate the obstacle location information into a specific data packet and send the data packet to the ATS system through the wireless communication network.

[0035] Step 130: ATS calculates the distance between the train and the obstacle based on the obstacle position information, and generates obstacle alarm position information and an alarm mark on the display interface of the target workstation based on the distance; wherein the obstacle alarm position information includes at least one of the kilometer mark of the obstacle location and the distance between the train and the obstacle; the alarm mark includes at least one of a first-level pop-up alarm prompt and an obstacle mark; the target workstation includes at least one of an ATS dispatching workstation and a maintenance workstation.

[0036] It should be noted that the ATS system is used to monitor the operating status of trains on the entire line and assist train dispatchers in managing train operations. After the ATS system receives the obstacle location alarm information sent by the ATP system, it will immediately display and record it and issue an alarm to the train dispatcher. The train dispatcher can take corresponding measures in a timely manner based on the display and alarm information of the ATS subsystem to ensure the safety and smoothness of train operation.

[0037] In this step, the content of the first-level pop-up alarm prompt may include basic information about the obstacle (such as location, type, distance, etc.), as well as recommended countermeasures (such as slowing down, stopping, etc.).

[0038] In this step, the obstacle icons are coded with different colors or shapes according to different types of obstacles (such as solid, liquid, gas, etc.) and danger levels (such as high, medium, low, etc.).

[0039] In this step, the obstacle identification includes an obstacle icon or an obstacle lock icon.

[0040] In this embodiment, the ATS system determines the real position of the obstacle compared to the train line based on the obstacle position information, converts the real position into a proportional value, and finally marks it on the electronic map on the corresponding display interface of the ATS system.

[0041] In this embodiment, the obstacle location information is displayed in detail at the ATS dispatch workstation and maintenance workstation for alarm; the alarm display content includes but is not limited to: ATS dispatch workstation first-level pop-up alarm, obstacle location kilometer mark and train distance from the obstacle.

[0042] Specifically, the obstacle alarm position information and alarm mark generated on the workstation display interface according to the distance include: (1) When the train identifies an obstacle and the obstacle does not enter the ITE system's blind spot, a first-level pop-up alarm prompt and obstacle icon are generated on the display interface of the ATS dispatching workstation; Figure 2 is a schematic diagram of the interface of the obstacle display in the ATS dispatch workstation provided by the present invention. Figure 2 In the illustrated embodiment, when the train identifies an obstacle ahead through binocular vision, laser radar, or millimeter-wave radar, and the obstacle does not enter the identification blind spot of the ITE system (the ITE blind spot is about 30 meters), the system will immediately generate a first-level pop-up alarm prompt on the display interface of the ATS dispatching workstation; and generate an obstacle icon (corresponding to the zigzag mark on the right side of F10) at the corresponding position of the display interface to intuitively display the location and type of the obstacle.

[0043] (2) When the train identifies an obstacle and the obstacle enters the ITE system's blind spot or the vehicle body, a first-level pop-up alarm prompt and an obstacle lock icon are generated on the display interface of the ATS dispatching workstation.

[0044] Figure 3 is a schematic diagram of the interface for displaying locked obstacles in the train window provided by the present invention. Figure 3In the illustrated embodiment, when the train recognizes an obstacle and the obstacle has entered the identification blind area of ​​the ITE system or the vehicle body, a first-level pop-up alarm prompt is generated on the display interface of the ATS dispatching workstation; however, unlike the previous case, the pop-up window at this time may contain more urgent prompt information, such as "stop immediately" or "emergency brake", because the obstacle has posed a direct threat to the safe operation of the train; at the same time, an obstacle locked icon (including a lock and a zigzag mark) is displayed above the train number window, indicating that the obstacle has been locked by the system and is continuously tracked.

[0045] In this embodiment, the shape, color and display effect of the obstacle lock icon can be personalized according to user needs; the above-mentioned first-level pop-up alarm prompt and obstacle identification are used to prompt the operator to make correct decisions and countermeasures in time, thereby ensuring the safe operation of the train.

[0046] The train safety operation control method provided by the embodiment of the present invention sends the obstacle information to the on-board controller VOBC when the intelligent train Eagle Eye ITE system of the train identifies the existence of an obstacle on the target line, brakes the train according to the alarm information based on VOBC, and forwards the obstacle position information to the train automatic monitoring system ATS through the train automatic protection system ATP. Finally, the ATS calculates the distance between the train and the obstacle according to the obstacle position information, and generates the obstacle alarm position information and alarm mark on the display interface of the target workstation according to the distance, thereby realizing real-time monitoring of obstacles and improving the intelligence level of autonomous driving vehicles, improving the train operation efficiency and safety, and enabling vehicles to better adapt to complex traffic environments, thereby achieving safe obstacle avoidance and correct driving decisions.

[0047] In some embodiments, the obstacle information also includes effective obstacle points; after the obstacle information is sent to the on-board controller VOBC, the train safe operation control method further includes: (1) Based on VOBC, the effective location of the obstacle is sent to the passenger information display system PIDS through the train control and management system TCMS and displayed.

[0048] Specifically, after receiving the obstacle data packet, VOBC will parse the effective point information of the obstacle and send the effective point information of the obstacle to the Passenger Information Display System (PIDS) through the network communication function of the Train Control and Management System (TCMS); after receiving the effective point information of the obstacle, PIDS will display the location, type and recommended countermeasures (such as deceleration, stopping, etc.) of the obstacle in real time on the display screen in the car according to the preset display rules.

[0049] (2) When the train is in FAM mode or CAM mode, the track surface image and obstacle history image are sent to the OCC large screen for display based on the closed-circuit television CCTV.

[0050] Specifically, when the train is in FAM mode or CAM mode, the CCTV in the driver's cab will take real-time pictures of the track surface in front of the train and send them to the OCC through the train communication network; at the same time, the central CCTV will record the historical images of obstacles, including the time, location, type and other information of the obstacle, and also send them to the OCC. The OCC large screen will display these images in real time so that OCC personnel can intuitively monitor the track surface conditions in front of the train and the historical records of obstacles.

[0051] The train safety operation control method provided by the embodiment of the present invention improves the safety of train operation and enhances the passengers' right to know and participation by quickly transmitting obstacle information to relevant systems after the train identifies an obstacle and realizing visual display of information through PIDS and CCTV. At the same time, OCC personnel can also monitor the track surface conditions in front of the train in real time through the CCTV system and make more accurate scheduling decisions.

[0052] Figure 4 This is the second flow chart of the train safety operation control method provided by the present invention. Figure 4In the illustrated embodiment, the ITE system actively identifies obstacles in real time. When the activated end ITE system identifies an obstacle, it forwards the obstacle identification result (obstacle information) to the on-board VOBC system. The VOBC system applies brakes to the train according to the alarm information. At the same time, VOBC sends the effective position of the obstacle to the TCMS system, which is forwarded by TCMS to the passenger information display system (PIDS), and the driver's cab is linked to illuminate the track surface camera image and push the camera image T moments before the obstacle is identified to the OCC large screen; VOBC also forwards the obstacle position information (determined based on link+offset) to the ATS subsystem via the on-board ATP system. The ATS system converts the obstacle position information, marks the obstacle position on the electronic map of the display interface, and displays the detailed obstacle position alarm at the ATS dispatch workstation and maintenance workstation, and the ATS pushes the display content to the OCC large screen for display.

[0053] Furthermore, CCTV includes CCTV in the driver's room and CCTV in the center; based on the closed-circuit television CCTV, the rail surface images and obstacle history images are sent to the OCC large screen and displayed including: based on the CCTV in the driver's room according to the input of the vehicle inspection personnel, the on-board CCTV video images are displayed; based on the central CCTV according to the input of the central dispatcher, the rail surface images and obstacle history images are displayed.

[0054] In this embodiment, the CCTV in the driver's cab is used to collect real-time images of the track surface in front of the train and send them to the train control center (OCC) through the on-board communication network; the central CCTV is used to store and manage historical images of obstacles, which include various types of obstacles encountered during the train operation and their location, type, time and other detailed information.

[0055] In this embodiment, when the train is running, the CCTV in the driver's cab will continuously capture images of the track surface ahead, and these images will be transmitted to the OCC in real time through the on-board communication network; the vehicle inspection personnel can select and adjust the video images of the CCTV in the driver's cab as needed through the on-board terminal or the remote monitoring interface; for example, when potential obstacles are found, the vehicle inspection personnel can zoom in or focus on specific areas for clearer observation and analysis; based on the input of the vehicle inspection personnel, the track surface images captured by the CCTV in the driver's cab will be sent to the OCC large screen for real-time viewing by the central dispatcher and other relevant personnel.

[0056] In this embodiment, the central CCTV will receive and store the track surface images from the CCTV in the driver's cab in real time, as well as the obstacle information obtained by other sensors (such as laser radar, cameras, etc.). This information is integrated into the obstacle history images and stored in the central database; the central dispatcher can retrieve and view the obstacle history images as needed through the OCC monitoring interface; for example, when it is necessary to analyze the obstacle situation during a certain train operation, the central dispatcher can enter a specific time range, train number and other conditions to obtain the relevant obstacle history images; based on the input of the central dispatcher, the obstacle history images stored in the central CCTV will be sent to the OCC large screen for the central dispatcher and other relevant personnel to analyze and make decisions.

[0057] In this embodiment, when the CCTV system detects a potential obstacle, it can automatically trigger the early warning mechanism of the train control system, such as deceleration, stopping, etc., to ensure the safety of train operation; in addition, when the CCTV in the driver's room collects important information, it can automatically notify the central CCTV for storage and management; at the same time, the central CCTV can also send the stored historical images of obstacles to the CCTV in the driver's room for playback and analysis as needed, so as to realize the linkage between the CCTV in the driver's room and the central CCTV and improve operational efficiency.

[0058] The train safe operation control method provided by the embodiment of the present invention collects and displays the track surface images and obstacle historical images in real time through the train CCTV system, provides intuitive and accurate information support for vehicle inspection personnel and central dispatchers, improves the safety and monitoring efficiency of train operation, and reduces the risk of human misjudgment and missed judgment.

[0059] In some embodiments, the obstacle information also includes an obstacle image; after generating the obstacle alarm position information and the alarm mark on the display interface of the target workstation according to the distance, the train safe operation control method also includes: sending an image retrieval instruction to the ITE system through the ATS; when the ITE system receives the image retrieval instruction, uploading the target obstacle image to the gateway computer; storing the target obstacle image in the database through the gateway computer for the ATS dispatching workstation to call.

[0060] In this embodiment, each time the ITE system recognizes an obstacle and issues an alarm, it will save a total of two pictures, namely, the image of the obstacle being recognized for the first time and the image of the obstacle disappearing in the non-blind area after parking.

[0061] In this embodiment, the obstacle image is generated by selecting and retaining the corresponding long-focus and short-focus cameras based on the distance between the obstacle identified by the ITE and the current train.

[0062] In this embodiment, the image retrieval instruction includes but is not limited to key parameters such as the location information and timestamp of the target obstacle.

[0063] In this embodiment, the database may be a local database or a remote database, and the database type is determined according to the architecture and configuration of the system.

[0064] In this embodiment, after the ATS system receives the obstacle alarm information, it automatically determines whether it is necessary to retrieve the image of the target obstacle according to preset rules and algorithms; if necessary, the ATS system sends an image retrieval instruction to the ITE system so that the ITE system can accurately find and retrieve the corresponding image.

[0065] In this embodiment, after receiving the image retrieval instruction, the ITE system retrieves and finds the image of the target obstacle from the stored image database according to the parameters in the instruction, and the ITE system uploads the target obstacle image to the gateway computer through the communication network; the gateway computer serves as a bridge connecting the ATS system and the ITE system, and is used to receive and forward image data.

[0066] In this embodiment, after receiving the target obstacle image, the gateway computer stores it in the database; when storing, the image will be assigned a unique identifier (such as an ID number, timestamp, etc.) so that the subsequent ATS dispatch workstation can easily call and view it.

[0067] In this embodiment, when the dispatcher needs to view the image of the target obstacle, he can issue a call instruction through the ATS dispatch workstation; the ATS system retrieves and finds the corresponding image from the database according to the parameters in the instruction (such as image ID number, timestamp, etc.), and then displays it on the display interface of the ATS dispatch workstation. By observing the image, the dispatcher can more intuitively understand the nature, size and urgency of the obstacle, so as to make more accurate judgments and decisions.

[0068] Furthermore, the ATS dispatch workstation calls the target obstacle image in any of the following ways: The same train calls one image at a time; the same dispatching workstation calls one image at a time, and ATS does not receive a new image if it has not completely received the image called last time.

[0069] The train safety operation control method provided by the embodiment of the present invention sends an image retrieval instruction to the ITE system through the ATS; when the ITE system receives the image retrieval instruction, the target obstacle image is uploaded to the gateway computer; the target obstacle image is stored in the database through the gateway computer for the ATS dispatching workstation to call, thereby enhancing the dispatcher's intuitive understanding of the obstacle situation and improving the safety and monitoring efficiency of train operation; at the same time, the method also realizes the collaborative work of the ATS system and the ITE system, and improves the overall performance and reliability of the system.

[0070] Figure 5 This is a flow chart of the train safety operation control method provided by the present invention. Figure 5 In the embodiment shown, the dispatcher selects the "Obstacle Image Query" menu on the top menu or train window on the ATS dispatch workstation according to the alarm prompt of the ITE identifying the obstacle to issue an image retrieval command. The ITE system receives the command and retrieves the image information recorded in the system content, and then uploads the image information to the ATS system through VOBC; the ATS system displays the image and pushes it to the OCC large screen for display; in addition, the dispatcher retrieves the specified obstacle alarm information image through the linkage prompt box on the ATS dispatch workstation, or selects all obstacle alarm information of the day in the top menu of the dispatch workstation to retrieve the image; when the dispatcher fails to retrieve the train obstacle image, the ATS system prompts: "Obstacle image acquisition failed, and the obstacle image cannot be downloaded.
