Train derailment emergency protection methods, devices, resource controllers and communication trains Technical Field

[0001] This invention relates to the field of train control technology, and in particular to a train derailment emergency protection method, device, resource controller, and communication train. Background Technology

[0002] Urban rail transit has become an important mode of transportation for people, and its primary task is to ensure the safe transport of passengers to their destinations. The safety of rail transit has always been a hot topic of public concern, and train derailment is a significant accident that jeopardizes rail transit safety.

[0003] During normal train operation, a derailment can cause anything from minor congestion and reduced efficiency in the area before and after the derailed train, to serious accidents resulting in loss of life and even endangering trains running on adjacent tracks. If a derailment is handled improperly and a collision occurs, the resulting casualties would be unimaginable. Therefore, emergency derailment response is crucial, and ensuring its safety, reliability, and timeliness relies heavily on the core train signaling control system.

[0004] With the development of technology, compared with the traditional Communication-Based Train Control System (CBTC), the Vehicle-Vehicle Based Train Control System (VBTC) is more intelligent and safer. However, the VBTC system has not yet formed a mature and complete emergency plan for handling train derailment emergency protection. Most of the time, train drivers handle the situation manually. Manual handling inevitably carries risks such as misjudgment, misoperation, slow reaction time, and inability to predict the accident ahead. It is impossible to carry out corresponding emergency protection measures safely, quickly and effectively after an accident occurs, and there is even a possibility of secondary accidents.

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0050] It should be noted that in the description of this invention, the terms "first," "second," etc., are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, the first object can be one or more.

[0051] The following description, in conjunction with the accompanying drawings, provides an exemplary description of the train derailment emergency protection method, device, resource controller, and communication train provided by the present invention.

[0052] Figure 1 is a flowchart illustrating one of the train derailment emergency protection methods provided by the present invention. Taking Figure 1 as an example, the method is applied to a first resource controller (RC), and the method includes:

[0053] Step 100: Upon receiving a command to establish a derailment protection zone from the derailed train, determine the safety protection zone for the derailed train.

[0054] Step 110: If it is determined that the safety protection area is only within the control area of ​​the first resource controller, a derailment protection area establishment request message is sent to all first communication trains, wherein the first communication trains are communication trains included in the control area of ​​the first resource controller.

[0055] Step 120: Upon receiving feedback messages from all the first communication trains requesting the establishment of the derailment protection zone, establish the derailment protection zone for the derailed train, and formulate emergency protection measures for the train based on the derailment protection zone. The feedback messages are used to indicate that the first communication train allows the first resource controller to establish the derailment protection zone.

[0056] Step 130: Send a target message containing the derailment protection area and the train emergency protection measures to each of the first communication trains, so that each of the first communication trains can perform train emergency protection processing based on the derailment protection area and the train emergency protection measures.

[0057] It should be noted that the execution entity of the train derailment emergency protection method provided in this embodiment of the invention is the core subsystem of the VBTC train control system based on vehicle-to-vehicle communication—the resource controller (RC). The RC adopts a two-out-of-two safe computer platform structure, enabling dual-system redundancy of equipment, data synchronization, voting, and fault self-shutdown functions. Through communication with the execution unit subsystem, the RC can drive and collect the status of trackside equipment such as signals, switches, and axle counters. It can also obtain relevant information from the ground and onboard systems through communication with other subsystems, including the onboard system. It possesses route control, signal control, switch control, platform control, resource management, train management, and other interlocking functions.

[0058] Specifically, in this embodiment of the invention, when the first resource controller (first RC) receives a derailment protection zone establishment command sent by the derailed train, the first RC determines the safety protection zone of the derailed train. If it determines that the safety protection zone is only within the control area of ​​the first RC, it sends a derailment protection zone establishment request message to all first communication trains. These first communication trains are those included within the control area of ​​the first RC. Upon receiving feedback messages from all first communication trains regarding the derailment protection zone establishment request message, the feedback messages indicate that the first communication trains allow the first RC to establish the derailment protection zone. That is, if it is determined that all first communication trains allow the first RC to establish the derailment protection zone, the first RC establishes the derailment protection zone for the derailed train and formulates train emergency protection measures based on the established derailment protection zone. Then, the first RC sends a target message containing the derailment protection zone and the train emergency protection measures to each first communication train, so that each first communication train can perform train emergency protection processing based on the derailment protection zone and the train emergency protection measures.

[0059] Optionally, a derailment protection zone for a derailed train can be established based on the safety protection zone of the derailed train.

[0060] It should be noted that when establishing a derailment protection zone, the first RC sends an establishment request to all first communication cars within its control area, and only establishes the derailment protection zone for the derailed train after obtaining permission from all first communication cars. This ensures the effectiveness of the established derailment protection zone.

[0061] It is understood that, in this embodiment of the invention, when a train derails, the train sends a derailment protection zone establishment command to its target RC. After receiving the derailment protection zone establishment command, the target RC will establish a derailment protection zone for the derailed train and formulate corresponding emergency protection measures for the communication trains near the derailed train, thereby avoiding more serious traffic accidents.

[0062] The train derailment emergency protection method provided by this invention, upon receiving a derailment protection zone establishment command from a derailed train, sends a derailment protection zone establishment request message to nearby communication trains. Only after confirming that all nearby communication trains are permitted to establish a derailment protection zone does the derailed train's derailment protection zone become established, ensuring its effectiveness. Based on this derailment protection zone, train emergency protection measures are formulated, and target messages containing the derailment protection zone and train emergency protection measures are sent to each nearby communication train. Each communication train then performs emergency protection processing based on the derailment protection zone and emergency protection measures, effectively realizing automated train derailment emergency protection processing based on vehicle-to-vehicle communication and improving the safety of train derailment emergency protection.

[0063] Optionally, after determining the safety protection zone of the derailed train, the method further includes:

[0064] If it is determined that the safety protection area spans the control area of ​​the first resource controller and the control area of ​​the second resource controller, a derailment protection area establishment request message is sent to all first communication trains and to the second resource controller, so that the second resource controller can forward the derailment protection area establishment request message to all second communication trains, wherein the second communication trains are communication trains included in the control area of ​​the second resource controller;

[0065] Upon receiving feedback messages from all the first communication trains requesting the establishment of the derailment protection zone, and upon receiving feedback messages from all the second communication trains requesting the establishment of the derailment protection zone forwarded by the second resource controller, a derailment protection zone for the derailed train is established, and emergency protection measures for the train are formulated based on the derailment protection zone.

[0066] The system sends a target message containing the derailment protection area and the train emergency protection measures to each of the first communication trains, so that each of the first communication trains can perform train emergency protection processing based on the derailment protection area and the train emergency protection measures. The system also sends the target message to the second resource controller, so that the second resource controller can forward the target message to each of the second communication trains, so that each of the second communication trains can perform train emergency protection processing based on the derailment protection area and the train emergency protection measures.

[0067] Specifically, in this embodiment of the invention, when the first RC receives a derailment protection zone establishment command sent by the derailed train, it determines the safety protection zone of the derailed train, and then judges the safety protection zone of the derailed train. If it is determined that the safety protection zone spans the control area of ​​the first RC and the control area of ​​the second RC (second resource controller), it sends a derailment protection zone establishment request message to all first communication trains and sends a derailment protection zone establishment request message to the second RC, so that the second RC can forward the derailment protection zone establishment request message to all second communication trains, which are communication trains included in the control area of ​​the second RC; then, upon receiving the derailment protection zone establishment request message from all first communication trains... Upon receiving a feedback message requesting the establishment of a derailment protection zone from all second communication trains forwarded by the second RC, a derailment protection zone for the derailed train is established. Based on the derailment protection zone, emergency protection measures for the train are formulated. Subsequently, the first RC sends a target message containing the derailment protection zone and the emergency protection measures to each first communication train, so that each first communication train can carry out emergency protection processing based on the derailment protection zone and the emergency protection measures. The first RC also sends the target message to the second RC, so that the second RC can forward the target message to each second communication train, so that each second communication train can carry out emergency protection processing based on the derailment protection zone and the emergency protection measures.

[0068] It is understood that in the embodiments of the present invention, the first RC and the second RC are adjacent.

[0069] It is understood that, in embodiments of the present invention, when the safety protection zone of a derailed train spans the control areas of different resource controllers, the established derailment protection zone and train emergency protection measures information are communicated to all communication trains near the derailed train through communication between the different resource controllers and communication between the resource controllers and the communication trains within their control areas, thereby effectively achieving emergency protection measures for all communication trains near the derailed train.

[0070] Optionally, determining the safety protection zone of the derailed train includes:

[0071] Based on the target configuration parameters in the first resource controller, the safety protection zone of the derailed train is determined;

[0072] The target configuration parameters include: the maximum permissible operating speed of the derailed train's operating line, the maximum gradient of the main line of the operating line, the vehicle parameters of the derailed train, and the body length of the trains normally operating on the operating line.

[0073] Specifically, in this embodiment of the invention, when the first RC receives the derailment protection zone establishment command sent by the derailed train, the safety protection zone of the derailed train can be determined based on the target configuration parameters in the first RC. The target configuration parameters include at least the maximum permissible operating speed of the derailed train's operating line, the maximum gradient of the main line of the operating line, the vehicle parameters of the derailed train, and the body length of the trains normally operating on the operating line.

[0074] It should be noted that a preset configuration file usually exists in the resource controller (RC). In this embodiment of the invention, the preset configuration file includes the aforementioned target configuration parameters.

[0075] Optionally, the vehicle parameters of the derailed train include the length and weight of the derailed train.

[0076] It is understood that the embodiments of the present invention can conveniently determine the safety protection zone of a derailed train by using the target configuration parameters in the first resource controller.

[0077] Optionally, determining the safety protection zone of the derailed train based on the target configuration parameters in the first resource controller includes:

[0078] Based on the target configuration parameters in the first resource controller, the safe protection distance of the derailed train is determined;

[0079] Based on the aforementioned safety protection distance, the safety protection zone for the derailed train is determined;

[0080] The safety protection distance includes a first preset distance in front of the derailed train and a second preset distance behind it; the first distance is greater than the emergency braking distance of the derailed train's operating line, which is calculated based on the maximum permissible operating speed of the derailed train's operating line, the maximum gradient of the main line of the operating line, and the vehicle parameters of the derailed train; the second distance is greater than the length of the train body of a normally operating train on the operating line.

[0081] Specifically, in this embodiment of the invention, in order to determine the safety protection zone of the derailed train based on the target configuration parameters in the first resource controller, the safety protection distance of the derailed train can first be determined based on the target configuration parameters in the first resource controller. The safety protection distance includes a first distance preset in front of the derailed train and a second distance preset behind it. The first distance is greater than the emergency braking distance of the derailed train's operating line. The emergency braking distance is calculated based on the maximum permissible operating speed of the derailed train's operating line, the maximum gradient of the main line of the operating line, and the vehicle parameters of the derailed train. The second distance is greater than the length of the train body of a normally operating train on the derailed train's operating line. Then, the safety protection zone of the derailed train is determined based on this safety protection distance.

[0082] Optionally, the safety protection area includes the area formed by the main line up, main line down and temporary parking line within the safety protection distance.

[0083] Specifically, in this embodiment of the invention, after obtaining the safe protection distance of the derailed train, the main line up line, main line down line and temporary stopping line within the safe protection distance can be determined, and then the area formed by the main line up line, main line down line and temporary stopping line within the safe protection distance is taken as the safe protection area of ​​the derailed train.

[0084] It is understood that the embodiments of the present invention first determine the safe protection distance of the derailed train based on the target configuration parameters in the first resource controller, and then, based on the safe protection distance, effectively and conveniently determine the safe protection area of ​​the derailed train.

[0085] Figure 2 is a second schematic flowchart of the train derailment emergency protection method provided by the present invention. Taking Figure 2 as an example, the method includes:

[0086] Step 200: When a train derailment is detected, the RC determines the safety protection zone of the derailed train based on the configuration data.

[0087] Step 210: RC determines the axle counter closest to the boundary of the safety protection zone based on the safety protection zone of the derailed train;

[0088] Step 220: The RC determines the derailment protection zone of the derailed train based on the axle counter closest to the boundary of the safety protection zone;

[0089] Step 230: Based on the derailment protection zone, the RC formulates corresponding emergency protection measures for communication trains traveling towards and away from the derailed train both inside and outside the derailment protection zone.

[0090] Step 240: The RC sends information containing the derailment protection zone and emergency protection measures to each communication train near the derailed train, so that each communication train can carry out corresponding emergency protection measures based on the derailment protection zone and train emergency protection measures.

[0091] Figure 3 is a schematic diagram of the derailment protection zone of the derailed train provided by the present invention. Taking Figure 3 as an example, when the communication train 3 (i.e., the derailed train in the figure) derails, the specific process of the train derailment emergency protection method provided by the embodiment of the present invention includes:

[0092] Step 1: Communication train 3 sends a command to its RC (Regulator) to establish a derailment protection zone. Upon receiving the command, the RC sends a request to all communication trains within its control area to establish a derailment protection zone. Each communication train, after determining it can stop before the derailed train, replies to the RC with permission to establish the derailment protection zone. Once all communication trains have replied with permission, the RC, based on its configuration data, extends the maximum protection distance L1 forward from the front of communication train 3 to point X, and extends the maximum protection distance L2 backward from the rear of communication train 3 to point Y. The mainline up line, mainline down line, and temporary stopping line included in the kilometer markers corresponding to X and Y constitute the safety protection zone for the derailed train.

[0093] In the above, L1 and L2 are the maximum protection distances determined based on the line operating conditions. Among them, L1 must be greater than the emergency braking distance of the line to ensure that the derailed train can come to a complete stop within the derailment protection zone. The emergency braking distance is calculated based on the maximum allowable operating speed of the line, the maximum gradient of the main line, and the vehicle parameters of the communication train 3. L2 must be greater than the length of a normally operating train on the line to prevent the derailed train from slipping out of the derailment protection zone.

[0094] Step 2: Based on the kilometer markers at X and Y determined in Step 1, find the axle counters that are closest to X and Y and outside the safety protection zone. These are the boundary axle counters of the derailment protection zone.

[0095] Step 3: Based on the boundary axle counters determined in Step 2, the area formed by connecting all the boundary axle counters, including the main line up line, the main line down line, and the temporary stop line, is the derailment protection zone of the communication train 3 (i.e., the dotted line in Figure 3).

[0096] Step 4: Based on the positions and directions of other communication trains near communication train 3, the RC takes appropriate measures for each communication train near the derailed train. Within the derailment protection zone, communication trains heading towards the centerline of the derailed train (trains 2 and 5 in Figure 3) will have their resources withdrawn; within the derailment protection zone, the resource status of communication trains leaving the centerline of the derailed train (trains 4 and 6 in Figure 3) remains unchanged. Outside the derailment protection zone, the available resources of a communication train heading towards the centerline of the derailed train (train 1 in Figure 3) will be withdrawn to the first section outside the derailment protection zone; outside the derailment protection zone, the resource status of a communication train leaving the centerline of the derailed train (train 7 in Figure 3) remains unchanged.

[0097] It should be noted that the centerline mentioned above refers to the kilometer marker at the midpoint between the front and rear of the derailed train. Simultaneously, the RC establishing the derailment protection zone will send the establishment status to its neighboring RCs. The neighboring RCs will then transmit the derailment protection zone information to the communication trains within their control area and take corresponding measures based on the aforementioned processing method.

[0098] Step 4: Communication trains near the derailed train will take appropriate emergency measures based on the protection zone information sent by the RC of their respective control areas and the location and operating status information sent by the derailed train. Within the derailment protection zone, communication trains heading towards the centerline of the derailed train (trains 2 and 5 in Figure 3) will take emergency braking measures; within the derailment protection zone, communication trains leaving the centerline of the derailed train (trains 4 and 6 in Figure 3) will maintain their original operation. Outside the derailment protection zone, the movement authorization MA of communication trains heading towards the centerline of the derailed train (train 1 in Figure 3) will be withdrawn to the boundary point of the derailment protection zone; outside the derailment protection zone, communication trains leaving the centerline of the derailed train (train 7 in Figure 3) will maintain their original operation.

[0099] Understandably, in this embodiment of the invention, when a train derailment is detected, the RC (Radio Control Center) determines the safety protection zone of the derailed train by extending the maximum protection distance forward and backward from the front and rear positions of the train, respectively, based on configuration data. Based on the safety protection zone, it determines the axle counter closest to the boundary of the safety protection zone. Based on the determined boundary axle counter, the derailment protection zone of the derailed train is demarcated. Within the derailment protection zone, communication trains traveling towards the derailed train withdraw resources and apply emergency braking, while communication trains traveling away from the derailed train maintain normal operation. Outside the derailment protection zone, the resources and movement authorization (MA) of communication trains traveling towards the derailment protection zone are withdrawn to the first segment outside the protection zone, while communication trains traveling away from the derailment protection zone maintain normal operation.

[0100] When a train derailment is detected, this invention creates a derailment protection zone for the derailed train and takes targeted and rapid emergency measures based on the location and direction of travel of nearby communication trains to avoid secondary accidents. It can quickly and accurately identify and avoid potential risks, minimize the damage caused by the derailment accident, and ensure the normal operation of other communication trains.

[0101] Furthermore, the train derailment emergency protection method provided in this embodiment of the invention does not rely on manual handling by the driver. Instead, it uses the RC subsystem in the VBTC signal system to detect danger and take corresponding measures in the first instance, ensuring the safety, reliability and speed of derailment protection.

[0102] Figure 4 is a flowchart of the third step of the train derailment emergency protection method provided by the present invention. Taking Figure 4 as an example, the method is applied to a communication train, and the method includes:

[0103] Step 400: Upon receiving a target message from the resource controller containing the derailment protection zone and emergency protection measures for the derailed train, obtain the location information and operating status information of the derailed train from the derailed train.

[0104] Step 410: Based on the derailment protection zone of the derailed train, the emergency protection measures for the train, and the location and operating status information of the derailed train, perform emergency protection processing for the train.

[0105] Specifically, the execution subject of the train derailment emergency protection method provided in this embodiment of the invention is a communication train. When the communication train receives a target message sent by its resource controller RC containing the derailment protection area and emergency protection measures of the derailed train, the communication train obtains the location information and operating status information of the derailed train from the derailed train, and then performs train emergency protection processing based on the derailment protection area, emergency protection measures, location information and operating status information of the derailed train.

[0106] Optionally, the operational status information of the derailed train may include whether the derailed train is an upgraded or non-upgraded communication train, and the current speed of the derailed train.

[0107] It is understood that the train derailment emergency protection method based on vehicle-to-vehicle communication provided in this embodiment of the invention does not rely on manual processing. The communication trains near the derailed train take corresponding emergency measures based on the derailment protection area information sent by their respective RC and the location and operating status information sent by the derailed train, thereby improving the timeliness of train derailment protection and handling.

[0108] It should be noted that even if communication between the train and the RC is interrupted, the train can still determine the location and operating status of surrounding trains through data exchange between trains, thus improving the reliability of train derailment protection.

[0109] The train derailment emergency protection method provided by this invention involves a communication train receiving a target message from a resource controller containing the derailment protection zone and emergency protection measures for the derailed train. The communication train then obtains the location and operating status information of the derailed train. Based on this information, the method performs emergency protection processing, effectively realizing automated train derailment emergency protection processing based on vehicle-to-vehicle communication and improving the safety of train derailment emergency protection.

Based on this derailment protection zone, train emergency protection measures are formulated, and target messages containing the derailment protection zone and train emergency protection measures are sent to each nearby communication train. Each communication train then performs emergency protection processing based on the derailment protection zone and emergency protection measures, effectively realizing automated train derailment emergency protection processing based on vehicle-to-vehicle communication and improving the safety of train derailment emergency protection.
