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.

The FAO system includes an ATP (Automatic Train Protection system) for Train safety Protection, and an ATO (Automatic Train Operation system) for safe Automatic driving.

The TIAS (Train Integration automation System) is a comprehensive data information platform, and forms the information of the systems such as vehicle, signal, power supply, environmental control, etc. into a tightly integrated whole, and realizes the monitoring of vehicle, power supply, etc. on the unified software, hardware and network platform.

A ZC (Zone Controller) is used as a core ground control device of the FAO system, and has a main function of generating and sending a Movement Authorization (MA) for a train within a control range thereof according to position information reported by a communication train and track occupation/free information provided by an access and trackside devices arranged in an interlocked manner, which is a hub for train-ground information processing, ensures the traveling efficiency and safe operation of the communication train in the FAO system, and has a capability of performing train management in various train control levels and driving modes.

CI (Computer Interlocking) is used to form a relationship in which control range signals, train occupancy detectors, switches and other signaling devices are linked and restricted.

The BTM (Balise Transmission Module) is a safety point information Transmission system, and information Transmission from the ground device to the vehicle-mounted device is realized by the transponder.

Fig. 1 is a schematic flow diagram of a remote speed-limiting operation control method provided by the present invention, and as shown in fig. 1, the method includes:

and step 110, if the ATP detects that the train to be controlled has fault degradation, the ATP applies emergency braking to the train to be controlled, and sends the parking position after the emergency braking to the ZC and sends a remote speed limit operation application and train fault information to the TIAS.

Specifically, in the embodiment of the invention, the train to be controlled is a subway train, and the main execution body of the method is an FAO system. Before the fault degradation occurs, the train to be controlled runs automatically through the ATO system. And when the train to be controlled breaks down, the FAO system reduces the automatic operation level. At the moment, when the ATP detects that the train to be controlled is in fault degradation, the emergency braking is immediately carried out on the train to be controlled, and the train to be controlled stops running. At this point, the ATP continues to maintain communication with the ATO, the TIAS, the ZC, and the CI.

At this time, the ATP may determine the state of the train, for example, set a preset condition to determine whether the train to be controlled satisfies a waiting state for performing the remote speed-limiting operation. If the train meets the preset running condition, the train can enter a remote speed-limiting running waiting state. Here, the preset operation conditions may be selected according to actual conditions, such as an operation mode before degradation of the train, an operation state of the BTM device, an operation state of the remaining electronic devices, and the like.

The parking position is a stop position on the track after emergency braking of the train to be controlled. And if the positioning function of the train to be controlled is normal, sending the actual position of the train after emergency braking, and if the train to be controlled cannot receive the positioning signal temporarily, calculating the estimated position of the train after emergency braking according to the position of the train when the positioning signal is lost, and taking the estimated position as the parking position. And the ATP sends the stopping position of the train to be controlled to the ZC after the train to be controlled enters a remote speed-limiting operation waiting state.

In addition, the ATP is also used for sending a remote speed limit operation application and train fault information to the TIAS. The remote speed-limiting operation application is used for indicating that the operation state of the train to be controlled can meet the speed-limiting operation, and requesting to obtain the scheduling permission of the TIAS. The train fault information is a specific reason for the train fault, so that a dispatcher or a system can analyze or alarm the fault.

And step 120, as most of the control systems on the train are in redundant arrangement, namely the train heads at two ends are arranged. At this time, according to the activation states of the ATP at the two ends of the train to be controlled, the corresponding ATP can be selected to communicate with the ZC.

Receiving a remote speed-limiting operation instruction and moving distance information sent by a ZC, relieving emergency braking of a train to be controlled by an ATP (automatic train protection) and forwarding the remote speed-limiting operation instruction and the moving distance information to an ATO (automatic train operation) so that the ATO controls the train to be controlled to operate at a limited speed; the remote speed-limiting operation instruction is generated by the TIAS based on the remote speed-limiting operation application and the train fault information and is determined by the ZC after checking; the movement distance information is determined by ZC based on the parking position.

Specifically, the TIAS generates a remote speed-limiting operation instruction according to the remote speed-limiting operation application and the train fault information. And the remote speed-limiting operation instruction is used for allowing the train to be controlled to carry out remote speed-limiting operation. For example, a scheduling staff of the TIAS determines the state of a train to be controlled according to the remote speed-limiting operation application and the train fault information, determines the vehicle operation condition and the line condition on the track where the train to be controlled is located, and generates a remote speed-limiting operation instruction based on the TIAS if the state of the train to be controlled meets the requirement and the state of the operation track also meets the requirement. The remote speed-limiting operation instruction can comprise information of a train executing the instruction, an operation direction of the train executing the instruction, a platform in front of the train executing the instruction and the like.

And after the TIAS generates a remote speed-limiting operation instruction, the instruction is sent to the ZC, and the ZC performs safety check. The ZC receives the remote speed-limiting operation instruction, checks the remote speed-limiting operation instruction according to a preset judgment condition, calculates the moving distance information if the remote speed-limiting operation instruction meets the preset judgment condition, and sends the remote speed-limiting operation instruction and the moving distance information to the ATP of the train to be controlled. Here, the preset determination condition may include whether the train corresponding to the remote speed-limiting operation instruction is in a remote speed-limiting operation waiting state, whether the train corresponding to the remote speed-limiting operation instruction has a movement authorization of a platform corresponding to the entry instruction, and whether the train operation direction is the same as the direction of the train activation end.

After receiving the remote speed-limiting operation instruction and the moving distance information sent by the ZC, the ATP can judge the operation state of the train again, if the preset operation condition is met, the emergency brake of the train to be controlled is released, the remote speed-limiting operation instruction and the moving distance information are sent to the ATO, and the ATO controls the train to be controlled to operate towards the front platform according to the preset speed. Here, the preset speed is a speed limit for train operation, and may be set according to a line condition. The preset operation conditions can be selected according to actual conditions, such as a working mode before degradation of the train, the operation state of the BTM equipment, the operation state of the other electronic equipment and the like.

According to the remote speed-limiting operation control method provided by the embodiment of the invention, after the ATP detects that the train to be controlled is degraded due to a fault, the stopping position after emergency braking is sent to the ZC, and a remote speed-limiting operation application and train fault information are sent to the TIAS; the method comprises the steps that a TIAS generates a remote speed-limiting operation application and train fault information, a ZC checks the remote speed-limiting operation instruction, the ZC determines moving distance information according to a parking position, and then removes emergency braking and speed-limiting operation according to the remote speed-limiting operation instruction and the moving distance information, so that the rescue efficiency of a fault train is improved, the fault train can rapidly enter the station, long-term detention of passengers in a region and delay of running of a follow-up train are avoided, the train operation efficiency is improved, and the rescue degree is reduced.

Based on the above embodiment, the remote speed limit operation instruction is generated according to the following steps:

and determining a remote speed-limiting operation instruction based on the number of the operation trains between the train to be controlled and the platform in front and the access locking state between the train to be controlled and the platform in front.

Specifically, the remote speed-limiting operation instruction can be determined by a TIAS dispatcher, or can be automatically determined by the TIAS according to a set control logic.

If there are other trains in the line between the train to be controlled and the platform ahead, there is a possibility that the trains will collide with each other. If the train to be controlled is to perform speed-limiting operation on the track, it is determined that no other train exists between the train and the platform in front.

The route locking means that after the route is selected, the switch and the enemy route related to the route are locked under the conditions that the switch position is determined to be correct and the enemy route is not established, so that the switch and the enemy route cannot be pulled and established, and the route locking is a necessary means for ensuring the operation safety of the train. If the train to be controlled is to perform speed-limiting operation on the track, it is necessary to confirm that the access between the train and the platform in front is in a locked state.

When the number of the running trains between the train to be controlled and the platform in front is confirmed to be zero and the access between the train to be controlled and the platform in front is in a locked state, a remote speed-limiting running instruction of the train to be controlled can be generated. For example, in the remote speed-limiting operation confirmation window popped up by the TIAS, the dispatcher inputs a train number, selects a train operation direction (ascending/descending), inputs a front platform number, and completes the operation through secondary confirmation.

Based on any of the above embodiments, the remote speed limit operation instruction is checked according to the following steps:

if the remote speed-limiting operation instruction meets the preset checking condition, determining that the remote speed-limiting operation instruction is valid;

the preset checking conditions comprise that the train corresponding to the remote speed-limiting operation instruction is in a remote speed-limiting operation waiting state, the movement authorization calculated for the train corresponding to the remote speed-limiting operation instruction can extend to a platform corresponding to the remote speed-limiting operation instruction, and the train operation direction corresponding to the remote speed-limiting operation instruction is consistent with the train activation end direction.

Specifically, the checking of the remote speed limit operation instruction is performed by the ZC.

The train corresponding to the remote speed-limiting operation instruction is in a remote speed-limiting operation waiting state and is used for indicating that the state of the train which is about to execute the remote speed-limiting operation instruction can meet the requirement of speed-limiting operation.

The movement authorization calculated for the train corresponding to the remote speed-limiting operation instruction can extend into a corresponding platform in the remote speed-limiting operation instruction, and is used for indicating that the train which is about to execute the remote speed-limiting operation instruction has the movement authorization to enter the corresponding platform in the remote speed-limiting operation instruction.

The train running direction corresponding to the remote speed-limiting running instruction is consistent with the direction of the train activating end, and is used for indicating that the indicated running direction of the train about to execute the remote speed-limiting running instruction is consistent with the direction of the train activating control end, namely the indicated running direction of the train is consistent with the actual running direction.

Based on any of the above embodiments, step 110 includes:

and if the train to be controlled meets the preset operation condition, sending a parking position to the ZC, and sending a remote speed-limiting operation application and train fault information to the TIAS.

Specifically, the purpose here is to judge whether the train to be controlled can perform remote speed-limiting operation after emergency braking. The ATP may determine the state of the train, for example, by setting a preset operating condition. Here, the pre-operation condition may be selected according to actual conditions, such as an operation mode before degradation of the train, an operation state of the BTM device, an operation state of the remaining electronic devices, and the like.

Based on any of the above embodiments, step 110 includes:

and if the train to be controlled does not meet the preset operation condition, transmitting train fault information to the TIAS.

Specifically, if the train to be controlled does not meet the preset operation conditions after emergency braking, the train cannot be operated at a remote speed limit. At the moment, the train fault information is sent to the TIAS, so that the TIAS can acquire the running state of the train, and therefore fault warning is conducted on a dispatcher, and the train is organized to conduct rescue work.

For example, the train is in FAM mode because the BTM device fails, the train degrades, the ATP applies emergency brakes, and the train stops. After degradation, ATP maintains communication with ATO, TIAS, ZC, CI systems. The ATP judgment condition is not met (because the BTM equipment fails), and the remote speed limit operation waiting state cannot be entered. The ATP sends train fault information to the TIAS, but does not send a remote speed-limiting operation application to the TIAS.

Based on any of the above embodiments, step 120 includes:

if the train to be controlled meets the preset operation condition, forwarding a remote speed-limiting operation instruction and moving distance information to the ATO;

and if the train to be controlled does not meet the preset operation condition, keeping the train to be controlled to adopt emergency braking.

Specifically, when the ATP receives the remote speed-limiting operation instruction and the movement distance information, the operation state of the train to be controlled may be determined again according to the preset operation condition in order to further increase the driving safety.

If the train to be controlled meets the preset operation condition, the ATP forwards the remote speed-limiting operation instruction and the moving distance information to the ATO, and the ATO controls the speed-limiting operation according to the remote speed-limiting operation instruction and the moving distance information. And if the train to be controlled does not meet the preset operation condition, the ATP keeps taking emergency braking for the train to be controlled, and simultaneously feeds back the non-execution condition and the reason of the remote speed-limiting operation instruction to the ZC and the TIAS.

Based on any embodiment, the preset operation conditions comprise that the train to be controlled is in an FAM mode or a CAM mode before degradation, BTM equipment of the train to be controlled normally operates, speed and distance measuring equipment of the train to be controlled normally operates, and ATP communication functions of the train to be controlled are normal.

Specifically, the train to be controlled is in a FAM (Full Automatic Mode) Mode or a CAM (deep Automatic Mode) Mode before degradation, and is used for indicating that the train to be controlled is in an Automatic operation state before degradation.

And the BTM equipment of the train to be controlled operates normally and is used for indicating that the transponder transmission unit of the train to be controlled can work normally.

The speed and distance measuring equipment of the train to be controlled runs normally, and is used for indicating that the speed measuring equipment and the distance measuring equipment on the train to be controlled can work normally, measuring the speed of the train to be controlled and measuring the actual running distance of the train to be controlled.

And the ATP communication function of the train to be controlled is normal, and the ATP is used for indicating that the ATP of the train to be controlled can normally communicate with the ATO, the ZC, the CI and the TIAS.

Based on any of the above embodiments, step 120 includes:

and if the train to be controlled meets the condition of upgrading the FAM mode, switching the control mode of the train to be controlled to the FAM mode.

Specifically, if the fault of the train to be controlled is eliminated in the remote speed-limited operation process, and the operation condition of the train meets the condition of upgrading the FAM mode, the control mode of the train can be switched to the FAM mode, and the train operates according to the control logic set by the FAM mode.

Based on any of the above embodiments, the embodiment of the present invention provides a method for performing remote speed-limiting operation control after modifying functions and interfaces of an existing FAO system.

The method comprises the following steps:

step 1, the train is in a FAM/CAM mode, the train is degraded, ATP applies emergency braking, and the train stops. After degradation, ATP maintains communication with ATO, TIAS, ZC, CI systems.

And step 2, after the ATP judgment meets the conditions, entering a remote speed-limiting operation waiting state, and simultaneously sending a train position report or a train estimated position report to the ZC. If the train loses the positioning, calculating an estimated train position report after the train is stably stopped according to the position when the positioning is lost; and if the train does not lose the positioning, normally sending a position report.

Here, the ATP determination condition needs to be satisfied at the same time, and includes:

before the degradation of the train, the mode is FAM/CAM, the BTM equipment is normal, the speed measuring and distance measuring equipment is normal, and the communication between ATP and ATO, ZC, CI and TIAS systems is normal.

And 3, after the train enters a remote speed-limiting operation waiting state, the ATP system sends a remote speed-limiting operation application and train fault information to the TIAS. And after receiving the remote speed-limiting operation application and the train fault information, the TIAS carries out corresponding alarm display on a TIAS dispatcher interface and pops up an operation prompt.

Step 4, the dispatcher can operate to allow or not allow the remote speed-limiting operation, if the dispatcher operates to allow the remote speed-limiting operation, the TIAS sends a remote speed-limiting operation instruction to the ZC; if the dispatcher does not allow the remote speed-limiting operation, the TIAS does not send a remote speed-limiting operation instruction to the ZC, and the ATP keeps applying emergency braking and waits for manual boarding rescue.

The dispatcher operates a flow allowing remote speed-limiting operation:

1) firstly, confirming that no other train exists between the fault train and the front platform, and the access between the fault train and the front platform is in a locking state;

2) and then in a remote speed limit operation confirmation window popped up by the TIAS: inputting a train number, selecting a train running direction (ascending/descending), inputting a front platform number, and finishing the operation through secondary confirmation.

And 5, after receiving the remote speed-limiting operation instruction, the ZC judges whether the train is allowed to operate towards the front platform or not, and feeds back whether the instruction is successfully executed or not to the TIAS, and if the instruction fails to be fed back, the reason for failure needs to be described.

Here, the condition that the ZC determines is required to be satisfied simultaneously to allow the train to operate to a platform ahead, and includes:

the train corresponding to the command is in a remote speed-limiting operation waiting state, the movement authorization calculated for the train can extend into the platform corresponding to the command, and the train operation direction in the command is consistent with the train activation end direction.

And 6, if the ZC judges that the train is allowed to run to the front platform, the ZC sends a remote running speed limit instruction and a movable distance to the corresponding activation end ATP. The calculation method of the movable distance comprises the following steps: and calculating the distance from the train to the operating stop point of the front platform according to the position report or the estimated position report sent by the ATP.

Step 7, after the ATP receives the authorization instruction and the movable distance, the ATP judges that the condition is met and forwards the command to the ATO, and meanwhile, emergency braking is relieved; if the condition is not met, then no transfer is made to the ATO and the emergency brake application is maintained. And meanwhile, the ATP feeds back whether the authorization instruction is successfully executed or not to the ZC and the TIAS, and if the feedback fails, the failure reason needs to be described.

Here, the ATP determination condition needs to be satisfied at the same time, and includes:

before the degradation of the train, the mode is FAM/CAM, the BTM equipment is normal, the speed measuring and distance measuring equipment is normal, and the communication between ATP and ATO, ZC, CI and TIAS systems is normal.

Step 8, after receiving the authorization instruction and the movable distance, the ATO controls the train to run forwards at a fixed speed limit, and if the train meets the condition of upgrading the FAM mode in the running process (the upgrading FAM condition is not different from the existing FAO system), the train is automatically upgraded to the FAM mode and then continues to run; and if the FAM cannot be upgraded to the FAM mode, continuing to operate in the remote speed-limiting operation mode.

Step 9, the train enters the station area: if the train is in a remote speed-limiting operation mode, the ATO calculates a train control curve according to the latest position information to control the train to accurately stop at the platform; and if the train is in the FAM mode, performing normal station entering operation according to the existing logic.

And step 10, the operation flow of the train after the train is accurately stopped at the platform is consistent with that of the existing FAO system.

The following description will take an example in which the dispatcher cannot execute the remote speed-limiting operation instruction without executing the correct operation.

The train is in FAM mode because the idle slip compensation fails, degradation occurs, positioning is lost, the ATP applies the emergency brake, and the train stops. After degradation, ATP maintains communication with ATO, TIAS, ZC, CI systems. And the ATP judges that the conditions are met, enters a remote speed-limiting operation waiting state, and simultaneously sends a train estimated position report to the ZC. After the train enters a remote speed-limiting operation waiting state, the ATP system sends a remote speed-limiting operation application and train fault information to the TIAS. And after receiving the remote speed-limiting operation application and the train fault information, the TIAS performs corresponding alarm display and pop-up operation prompt on a dispatcher interface. Dispatcher operation allows remote speed-limiting operation: 1) firstly, confirming that no other train exists between the fault train and the front platform, and the access between the fault train and the front platform is in a locking state; 2) and then in a remote speed limit operation confirmation window popped up by the TIAS: inputting train number (the dispatcher inputs error in this step), selecting the train running direction as ascending, inputting the number of the front platform, and completing the operation through secondary confirmation.

And after receiving the remote speed-limiting operation instruction, the ZC judges that the train in the instruction is in a non-remote speed-limiting operation waiting state, does not meet the condition of allowing the train to operate towards the front platform, and feeds back the instruction execution failure and the failure reason to the TIAS. The TIAS performs execution failure feedback and failure reason display, and the dispatcher can select whether to issue a remote speed-limiting operation instruction again through a menu. This example is no longer commanded.

The following description takes the successful execution of the remote speed-limited operation as an example.

The train is in FAM mode because the idle slip compensation fails, degradation occurs, positioning is lost, the ATP applies the emergency brake, and the train stops. After degradation, ATP maintains communication with ATO, TIAS, ZC, CI systems.

And after the ATP judgment meets the conditions, entering a remote speed-limiting operation waiting state, and simultaneously sending a train estimated position report to the ZC.

After the train enters a remote speed-limiting operation waiting state, the ATP system sends a remote speed-limiting operation application and train fault information to the TIAS. And after receiving the remote speed-limiting operation application and the train fault information, the TIAS performs corresponding alarm display and pops up an operation prompt on a dispatcher interface.

Dispatcher operation allows remote speed-limiting operation: 1) firstly, confirming that no other train exists between the fault train and the front platform, and the access between the fault train and the front platform is in a locking state; 2) and then in a remote speed limit operation confirmation window popped up by the TIAS: inputting a train number, selecting the train running direction as ascending, inputting a front platform number, and finishing the operation through secondary confirmation.

And after receiving the remote speed-limiting operation instruction, the ZC judges that the condition that the train is allowed to operate to the front platform is met, and feeds back the instruction to the TIAS to be successfully executed.

And the ZC sends a remote operation speed limit instruction and a movable distance to the corresponding activation end ATP.

After the ATP receives the authorization instruction and the movable distance, the ATP judges that the conditions are met and forwards the command to the ATO, and meanwhile, emergency braking is relieved.

And after receiving the authorization instruction and the movable distance, the ATO controls the train to operate forwards at a fixed speed limit, in the running process of the train, the positioning is reestablished after passing through two continuous transponders, the train meets the condition of upgrading the FAM mode, and the train automatically upgrades to the FAM mode and then continues to operate.

And the train enters the station area, and normal station entering operation is carried out according to the existing FAM mode logic.

And normal door opening and closing operation is carried out after the train is accurately stopped at the platform.
