Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Fig. 1 is a schematic flow chart of an automatic train test pulling method provided by the present invention. The automatic train test pulling method of the present invention is described below with reference to fig. 1. As shown in fig. 1, the method includes: and step 101, receiving a trial pull command sent by the ATS system.
The execution subject of the embodiment of the present invention is an automatic train test pull device. The automatic train trial-pulling device in the embodiment of the invention can be a vehicle-mounted controller of a first train.
A vehicle-mounted controller (VOBC) can supervise and control the train. Typically, a train carries one or more onboard controllers.
Fig. 2 is a schematic diagram of a train which is tried to be pulled in the automatic train trying method provided by the invention. As shown in fig. 2, after the first train 201 is coupled to the second train 202, the first train 201 and the second train 202 may be tried.
The second train 202 is a coupled train, and before the first train 201 is coupled with the second train 202, the second train 202 first stops at a preset position and waits for the first train 201 to be coupled therewith. The couplers of the first train 201 and the second train 202 are referred to as a target coupler 203 of the first train and a target coupler 204 of the second train, respectively.
After the second train 202 stops at the preset position, the first train 201 drives to the second train 202 to collide with the second train 202 in the forward direction, so that the target coupler 203 of the first train is connected with the target coupler 204 of the second train, and the coupling of the first train 201 and the second train 202 is completed. The end of the first train 201 coupled to the second train 202 by a coupler may be referred to as the coupling end of the first train 201 and the coupling end of the second train 202, respectively. The end of the first train 201 not coupled to the second train 202 by a coupler may be referred to as the non-coupled end of the first train 201 and the non-coupled end of the second train 202, respectively.
The first train 201 and the second train 202 may each carry one or more onboard controllers. The automatic trial pull method according to the present invention will be described below by taking as an example that the first train 201 and the second train 202 each have one onboard controller mounted thereon. The onboard controller of the first train 201 is denoted as VOBC1, and the onboard controller of the second train 202 is denoted as VOBC 2.
An Automatic Train Supervision (ATS) system is a subsystem of an Automatic Train Control (ATC) system, and the ATS system is coordinated with other subsystems in the ATC system, so that management and Control of trains and signal devices can be realized.
In the event that automatic pull-test of the first train 201 and the second train 202 is required, the ATS system may send a pull-test command to the VOBC 1. For example: during automatic train coupling based on the FAO, the ATS system can send a trial pull command to the VOBC 1; alternatively, when the first train 201 and the second train 202 are automatically tried to be pulled according to actual needs, the operator may input an instruction indicating the start of the automatic trial pulling, and after receiving the instruction indicating the start of the automatic trial pulling, the ATS system may send a trial pulling command to the VOBC 1.
VOBC1 can receive the try-pull command sent by the ATS system.
As shown in fig. 2, the trial pull direction of the first train 201 is opposite to the direction in which the second train 202 is located. After the first train 201 is coupled with the second train 202, a new train, called a third train, can be formed. The running direction of the third train may be the opposite direction of the trial pull direction of the first train 201, or may be the same direction as the trial pull direction of the first train 201.
And 102, responding to the trial pull command, sending trial pull application locking information to the target area controller, so that the target area controller sends first information indicating that trial pull is allowed to the on-board controller of the first train under the condition that the trial pull condition is met.
Zone Controllers (ZCs) are part of the ground equipment. Each zone controller corresponds to one control zone respectively, and functions of providing movement authorization and the like for the train can be realized in the corresponding control zone.
The target zone controller may refer to a zone controller corresponding to a track that needs to be occupied by the first train 201 and the second train 202 for automatic trial-and-pull. The target zone controller may be one or more.
The section occupied by the first train 201 and the second train 202 for the automatic trial pull is set in advance. The section occupied by the first train 201 and the second train 202 to perform the automatic trial pull may be set as the target trial pull area.
In order to ensure the safety of the first train 201 and the second train 202 during the automatic trial pulling process, before the automatic trial pulling of the first train 201 and the second train 202, an area requiring locking may be determined based on a target trial pulling area, and the area requiring locking may be locked. The above-described section to be locked may be referred to as a trial locking area.
After receiving the trying pull command sent by the ATS system, the VOBC1 may send, in response to the trying pull command, trying pull application locking information carrying information of the target trying pull area to the target area controller. The information of the target trial-drawing area may include position information of the target trial-drawing area, and the like.
The information of the target trial-pull area may be predetermined according to actual conditions. Before the automatic trial drawing is performed by the automatic trial drawing method, the information of the target trial drawing area can be pre-configured in the VOBC1, so that the VOBC1 can send trial drawing application locking information carrying the information of the target trial drawing area to the target area controller according to the pre-configuration.
Note that, since the VOBC1 periodically transmits the lock information of the trial pull application to the target area controller, the target area controller also periodically returns the first information indicating that trial pull is permitted or the information indicating that trial pull is prohibited to the VOBC 1.
For the trial pull application locking information sent in any period, after the target area controller receives the trial pull application locking information sent by the VOBC1, it can be determined whether the trial pull condition has been met. If it is determined that the trial pull condition is currently met, it may be indicated that there is no potential safety hazard in the current automatic trial pull, and the target area controller may return first information indicating that trial pull is allowed to the VOBC 1.
The specific process of the target area controller judging whether the trial pull condition is currently satisfied may include: under the condition that it is determined that the first train 201 meets the first condition based on the trial pull application locking information, a trial pull locking request is sent to a computer interlocking subsystem (CI) so that the computer interlocking subsystem receives the trial pull locking request, and under the condition that it is determined that the target trial pull area meets the second condition based on the trial pull application locking information, second information indicating that the trial pull locking area is successfully locked is returned to the target area controller after the trial pull locking area determined based on the target trial pull area is locked.
Fig. 3 is a flowchart of the processing of the target area controller in the automatic train test pulling method provided by the present invention. As shown in fig. 3, after the target area controller receives the trial pull application locking information sent by the VOBC1, the information of the target trial pull area can be obtained.
Based on the information of the target trial pull area, the target area controller may start to determine whether the first train 201 satisfies the first condition. The first condition may include that the first train 201 has no other train in the target driving interval in the trial-pull direction, and the train area corresponding to the first train 201 is located in the target trial-pull area.
As shown in fig. 3, based on the position information of the target trial-pull area, it is possible to first determine whether or not there is another train in the target travel section in the trial-pull direction of the first train 201. The target travel section may be predetermined according to a distance that the first train 201 may travel in the trial-pull direction. Determining that the first train 201 has no other train within the target travel section in the trial-pull direction can prevent the first train 201 from colliding with other trains during the trial-pull process.
If it is determined that there is another train in the target travel section in the trial-pull direction of the first train 201, the target area controller may return information indicating that trial-pull is prohibited to the VOBC 1.
If it is determined that there is no other train in the target travel section of the first train 201 in the trial-pull direction, it may be determined whether the train area 205 corresponding to the first train is located in the target trial-pull area based on the position information of the target trial-pull area. The train area 205 corresponding to the first train may refer to a safety envelope of the first train 201, and is determined based on the acquired position information of the first train 201.
If it is determined that the train region 205 corresponding to the first train is not located in the target trial pull region, the target region controller may return information indicating that trial pull is prohibited to the VOBC 1.
After determining that the train area corresponding to the first train 201 is located in the target trial pull area, the target area controller may send a trial pull locking request carrying information of the target trial pull area to the computer interlocking subsystem.
It should be noted that, in the embodiment of the present invention, the sequence of determining whether there are other trains in the target driving area of the first train 201 in the trial-pull direction and determining whether the train area corresponding to the first train 201 is located in the target trial-pull area by the target area controller is not specifically limited, but the target area controller may send the trial-pull locking request to the computer interlocking subsystem only when the above two conditions are simultaneously satisfied.
After the target area controller receives the message which is returned by the computer interlocking subsystem and represents the trial locking result, whether the trial locking area is successfully locked can be judged according to the trial locking result.
If the second information indicating that the trial locking area locking is successful is received, it may be determined that the trial locking area locking is successful, and a first message indicating that trial locking is allowed may be sent to the VOBC 1.
If a message indicating that the trial locking area locking failed is received, it may be determined that the trial locking area locking failed, and a message indicating that trial locking is prohibited may be sent to the VOBC 1.
Fig. 4 is a schematic processing flow diagram of a computer interlocking subsystem in the automatic train test pulling method provided by the invention. As shown in fig. 4, after receiving the trial pull locking request sent by the target area controller, the computer interlocking subsystem may obtain information of the target trial pull area.
Based on the information of the target trial pull area, the computer interlocking subsystem can judge whether the target trial pull area meets a second condition. The second condition may include that the target trial-pull area is in an idle state, the target trial-pull area meets the overrun condition, the operation protection switch corresponding to the target trial-pull area is not activated, and the switch-on direction of the switch in the target trial-pull area is the same as the target switch-on direction.
As shown in fig. 4, based on the location information of the target trial pull area, it may be first determined whether the target trial pull area is in an idle state.
If the target trial pull area is judged and known not to be in an idle state, the computer interlocking subsystem can return a message indicating that the target trial pull area is failed to be locked to the target area controller. After the target area controller receives the above-described message indicating that the target trial pull area locking has failed, information indicating that trial pull is prohibited may be returned to the VOBC 1.
If the target trial-pulling area is judged and known to be in an idle state, whether the target trial-pulling area meets the overrun condition can be judged. The overrun condition may be predetermined according to actual conditions. Whether the target trial pull area meets the overrun condition or not is judged, and potential safety hazards caused by overrun can be prevented when the first train 201 is automatically tried to be pulled.
If the target trial-pull area is judged and known not to meet the overrun condition, the computer interlocking subsystem can return a message indicating that the target trial-pull area is locked unsuccessfully to the target area controller.
If the target trial pull area meets the overrun condition, whether the operation protection switches (SPKS) corresponding to the target trial pull area are activated can be judged.
If the operation protection switch corresponding to the target trial pull area is judged to be activated, the computer interlocking subsystem can return a message indicating that the target trial pull area is failed to be locked to the target area controller.
If the operation protection switch corresponding to the target trial-pull area is not activated, whether the turnout opening direction in the target trial-pull area is the same as the target opening direction or not can be judged based on the predetermined target opening direction of the turnout in the target trial-pull area.
If the switch opening direction in the target trial pulling area is the same as the target opening direction, the computer interlocking subsystem can determine a trial pulling locking area based on the target trial pulling area and can lock the trial pulling locking area. After the trial locking area is successfully locked, second information indicating that the trial locking area is successfully locked may be returned to the target area controller.
It should be noted that the target opening direction of the switch in the target trial-pull area may be predetermined.
It should be noted that, in the embodiment of the present invention, it is not specifically limited to determine, by the computer interlocking subsystem, whether the target trial pull area is in an idle state, whether the target trial pull area satisfies an overrun condition, whether an operation protection switch corresponding to the target trial pull area is activated, and whether the direction of opening of a switch in the target trial pull area is the same as the direction of opening of a switch in the target trial pull area, but the computer interlocking subsystem may lock the trial pull locking area only if the four conditions are simultaneously satisfied, and after the locking is successful, return second information indicating that the trial pull locking area is successfully locked to the target area controller.
After receiving the second information which is sent by the computer interlocking subsystem and indicates that the trial locking of the locking area is successful, the target area controller can determine that the trial locking condition is met currently.
And 103, after receiving the first information sent by the target area controller, controlling the first train to try pulling.
Specifically, the first train 201 may receive first information indicating that the trial pull is allowed, which is sent by the target zone controller, and after receiving the first information, control the first train 201 to run in the trial pull direction to perform the trial pull.
It should be noted that, since the VOBC1 periodically sends the locking information of the trial pull application to the target area controller, for any period, the target area controller sends the first information indicating that the trial pull is allowed to the VOBC1 after determining that the trial pull is currently satisfied; alternatively, after determining that the trial condition is not currently satisfied, information indicating that trial pull is prohibited is sent to the VOBC 1.
After receiving the information indicating that the trial pull is prohibited, the VOBC1 may control the first train 201 to perform emergency braking, may exit the automatic hitching state, and may transmit information indicating that the automatic trial pull has failed to the ATS system. After receiving the information indicating the automatic trial pull failure, the ATS system may send an alarm according to the information to prompt the scheduling staff of the automatic trial pull failure. The information indicating the automatic trial pull failure can also carry the reason causing the automatic trial pull failure, for example, the automatic failure caused by failing to meet a certain condition is convenient for a scheduling person to analyze the reason according to the information.
And step 104, determining a trial pulling result based on the state information of the first train in the trial pulling process.
Specifically, after the VOBC1 controls the first train 201 to try to pull, the first train 201 may feed back the linkage information feedback of the first train 201 to the VOBC 1.
After receiving the linkage information feedback, the VOBC1 can start to determine the result of the trial pull.
The VOBC1 can determine the result of the trial pull by determining whether the first train 201 satisfies the third condition within the target time period in the trial pull process. Wherein the third condition may include; in the target time period, the mechanical coupling state of the coupling end of the first train 201 is "coupled", the running speed of the first train 201 is lower than the speed threshold, and the displacement of the first train 201 is smaller than the displacement threshold.
Fig. 5 is a flowchart of a result of the trial pull determined by the on-board controller of the first train in the automatic trial pull method for a train provided by the present invention. As shown in fig. 5, after receiving the linkage information feedback, the VOBC1 may first determine whether the mechanical linkage state of the linkage end of the first train 201 is "linked". The mechanical coupling state of the train coupling end is "coupling", which means that the coupler of the train coupling end is connected with the couplers of other trains.
If it is determined that the mechanical coupling state of the first train 201 coupling end is not "coupled", it may be determined that the result of trial pull is a failure. If it is determined that the mechanical coupling state of the coupling end of the first train 201 is "coupled", it may be determined whether the running speed of the first train 201 is lower than a speed threshold.
If it is determined that the traveling speed of the first train 201 is higher than the speed threshold, the result of the trial pull may be determined to be a failure. If it is determined that the traveling speed of the first train 201 is lower than or equal to the speed threshold, it may be determined whether the displacement of the first train 201 after the trial start is smaller than the displacement threshold. If it is determined that the displacement of the first train 201 is greater than or equal to the displacement threshold, the trial pull result may be determined to be a failure. If it is determined that the displacement of the first train 201 is smaller than the displacement threshold, it may be determined whether the target time period is reached. If it is determined that the target time period has not been reached, the process may return to determining whether the mechanical coupling state of the coupling end of the first train 201 is "coupled", and sequentially perform the determination according to the above determination process. If the target time interval is judged and known to be reached, the result of trial pull can be determined to be successful.
It should be noted that the target time period may refer to a certain time period after the first train 201 starts trying to pull. The target time interval may be determined according to actual conditions, and specific values of the target time interval are not specifically limited in the embodiments of the present invention.
It should be noted that the speed threshold and the displacement threshold may be determined according to actual situations. The specific values of the speed threshold and the displacement threshold are not particularly limited in the embodiments of the present invention.
In the embodiment of the present invention, the order of the VOBC1 for judging the above conditions is not particularly limited. However, the first train 201 needs to satisfy the above conditions at the same time, so that the result of the trial pull can be determined to be successful.
According to the embodiment of the invention, the onboard controller of the first train receives the trial-pull command sent by the ATS, sends the trial-pull application locking information to the target area controller, and controls the first train to perform trial-pull after receiving the first information which is sent by the target area controller under the condition of determining that the trial-pull condition is met currently and indicates that the trial-pull is allowed, and determines the trial-pull result, so that the train can be automatically tried more efficiently, the equipment cost is not increased in the automatic trial-pull process, the operation efficiency of the train can be improved, and the availability of an FAO system and/or a CBTC system can be improved.
Based on the content of the foregoing embodiments, before receiving the pull test command sent by the ATS system, the method further includes: and sending the coupling state of the first train to the ATS system, so that the ATS system sends a pull-test command to an on-board controller of the first train under the condition that the target coupler of the first train and the target coupler of the second train are determined to be in the coupling state.
Specifically, before the first train 201 and the second train 202 are tried to be pulled by the automatic trying to pull method provided by the present invention, it is required to determine that the target coupler 203 of the first train and the target coupler 203 of the second train are in a coupled state.
The ATS system may determine that the target coupler 203 of the first train and the target coupler 204 of the second train are in a coupled state if it determines that the first train 201 and the second train 202 satisfy the fourth condition. Wherein the fourth condition may include: the first train 201 and the second train 202 are in the process of being coupled, and the mechanical coupling state of the coupling end of the first train 201 is "coupled", and the mechanical coupling state of the coupling end of the second train 202 is "coupled".
The VOBC1 and VOBC2 may transmit the mechanical hitching status of the hitching end of the first train 201 and the mechanical hitching status of the hitching end of the second train 202, respectively, to the ATS system.
When a plurality of onboard controllers are mounted on the first train 201 and the second train 202, the onboard controllers provided at the train head transmit the mechanical coupling state of the train coupling end. For example: each of the first train 201 and the second train 202 has 2 onboard controllers mounted thereon and located at the head and tail of the train, respectively. The onboard controllers located at the head of the first train 201 may be designated as VOBC1, the onboard controllers located at the tail of the first train 201 may be designated as VOBC3, the onboard controllers located at the head of the second train 202 may be designated as VOBC2, and the onboard controllers located at the tail of the first train 202 may be designated as VOBC 4. The mechanical coupling status of the coupling end of the first train 201 and the mechanical coupling status of the coupling end of the second train 202 are transmitted to the ATS system by the VOBC1 and the VOBC2, respectively.
