[0041] 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.

[0042] In actual applications, after the dispatching system sends the operation plan to the train's onboard signal subsystem, the onboard signal subsystem autonomously calculates the required trackside resources and applies to the trackside controller based on the urgency of the resource demand. During the operation, the dispatching system is used to enable the train to actively exchange information with adjacent trains, thereby achieving safer, more efficient and more economical goals through vehicle-ground interlocking and vehicle-to-vehicle coordination.

[0043] In this embodiment, the intelligent object controller system monitors the communication status between the train's onboard signal subsystem and the dispatching system in real time. When it detects that the communication between the train's onboard signal subsystem and the dispatching system is interrupted and the train enters the degraded mode, the train is controlled to operate in a degraded manner to ensure that the train can continue to operate safely and automatically to the end of the route.

[0044] Combine the following Figure 1-Figure 3 A train degradation operation method of the present invention is described.

[0045] Figure 1 This is one of the flow charts of the train downgrade operation method provided by the present invention, such as Figure 1 As shown, the method includes:

[0046] Step 100, when the train enters the degradation mode, determining the movement authorization range of the train and the platform parking area of ​​the train, and calculating the target degradation path end point of the train according to the movement authorization range and the platform parking area;

[0047] It should be noted that the downgraded mode refers to a mode with reduced functions and lower levels than the previous mode. In this embodiment, the downgraded mode refers to the train being downgraded from the autonomous operation mode to the station automatic control mode, that is, a mode in which the train control is manually performed.

[0048] In this step, since the manual downgrade path endpoint setting cannot be performed in time by the personnel in the station automatic control room in some cases, in order to avoid the situation where the manual downgrade cannot be processed in time, the train can still continue to run safely to the path endpoint in this embodiment.

[0049] Specifically, the movement authorization range of a train refers to the movement authorization range calculated based on the line information and train travel path information provided by the regional control center of the train after the train enters the degraded mode, and the platform parking area of ​​the train refers to the platform parking area closest to the train in the train operation plan.

[0050] In this step, when the mobile authorization range is within the platform parking area, the end point of the platform parking area is used as the target downgrade path end point of the train. When the mobile authorization range is not within the platform parking area, the target downgrade path end point of the train is calculated based on the positional relationship between the mobile authorization range and the platform parking area.

[0051] Step 200, obtaining the operating parameters of the train, and calculating the buffer time of the train according to the operating parameters of the train and the end point of the target degradation path;

[0052] Specifically, the operating parameters of the train include the operating speed of the train and the acceleration of the train under safe operation when decelerating in the degraded mode.

[0053] In this step, the buffer time between the train's current position and the target degraded path end point is calculated based on the distance between the train's current position and the target degraded path end point, the train's current running speed, and the acceleration of the train when decelerating in the degraded mode.

[0054] Step 300: If no control instruction carrying the end point of the artificial degradation path is received within the buffer time, the train is controlled to stop at the end point of the target degradation path.

[0055] Specifically, the artificial degradation path end point refers to the path end point that is manually set autonomously by the train control system in the station automatic control room.

[0056] In this embodiment, when no manually sent control instruction is received within the buffer time, the train is degraded according to the target degrade path endpoint calculated by the intelligent object controller system.

[0057] In other words, in this embodiment, if no manually triggered control command is received, it is processed in automatic degradation mode, thereby ensuring that the train can continue to run safely and automatically to the end of the path when no human degradation control is performed. Compared with the emergency stop and waiting for manual processing in the prior art, this embodiment not only saves labor costs and time costs, but also avoids affecting the subsequent train operation.

[0058] Therefore, when the train is downgraded to the station automatic control mode, this embodiment determines the target downgrade path endpoint with the highest safety based on the train's current authorized movement range and the status of the platform parking area closest to the train, and calculates the buffer time corresponding to the train's operation to the target downgrade path endpoint based on the train's operating parameters. Based on the buffer time, it can be ensured that the train can be parked safely, labor costs and time costs can be saved, and further avoid affecting the subsequent train operation.

[0059] Based on the above embodiment, the step of calculating the target degradation path endpoint of the train according to the movement authorization range and the platform parking area includes:

[0060] In the case where the platform parking area is within the movement authorization range, the end point of the movement authorization range is used as the target degradation path end point of the train.

[0061] Specifically, when the starting point and the end point of the platform parking area are both within the movement authorization range, it indicates that the train can continue to run safely to the platform parking area.

[0062] It should be noted that when the train runs near the platform parking area, if there is no train ahead of the train, the end point of the train's authorized movement range is the end point of the platform parking area. Therefore, in this embodiment, the end point of the authorized movement range can be used as the end point of the train's target downgrade path, thereby controlling the train to continue to run safely and automatically to the platform parking area of ​​the train operation plan, thereby avoiding affecting the subsequent train operation.

[0063] Further, based on the above embodiment, the step of calculating the target degradation path endpoint of the train according to the movement authorization range and the platform parking area includes:

[0064] In the case where the platform parking area is not within the movement authorization range, determining the turnout type of the target turnout located ahead of the train;

[0065] In the case where the turnout type is a crossover turnout, determining a state of a target turnout lock at a position closest to the train on the crossover turnout;

[0066] When the target switch lock is in the reverse position and the train does not meet the reverse position requirement of passing through the target switch lock, the first target protection point on the crossover switch closest to the train is used as the target degradation path end point of the train.

[0067] Specifically, the platform parking area is not completely within the movement authorization range, which specifically means that the end point of the movement authorization range is located before the starting point of the platform parking area.

[0068] The target turnout refers to the turnout that is located on the running line in front of the train and is closest to the train.

[0069] In this step, when the movement authorization range is in front of the platform parking area, it indicates that the train has not run near the platform parking area. Generally, there is a switch between the train and the platform parking area, and the train passing conditions are different under various switches. Therefore, in this embodiment, the type of switch located in front of the train and closest to the train is first determined, so as to perform different degradation operation controls based on different types of switch, thereby ensuring that the train can run safely to the end of the path without affecting the operation of other trains.

[0070] Among them, the target switch lock refers to the lock that controls the switch intersection closest to the train in a positioned or reversed state. When it is in a positioned state, it indicates that the train can continue to run straight along the main switch track of the switch track to the platform parking area; when it is in a reversed state, it indicates that the train needs to stop, or change tracks along the secondary switch track of the switch track to the main switch track on other running lines.

[0071] Specifically, failure to pass the target switch lock means that the train is not granted permission to pass through the secondary switch of the target switch, that is, the resource lock on the target switch is not authorized to the train.

[0072] In this embodiment, when there is a crossing switch in front of the train, the target switch lock is in the reverse state and the train cannot pass through the secondary switch of the target switch, it means that the train cannot pass through the target switch, and the train is controlled to stop safely at the first target protection point closest to the train, that is, the train is controlled to stop at the protection point at the target switch, so as to avoid the train from mistakenly entering the switch and affecting other trains.

[0073] Further, based on the above embodiment, after determining the turnout type of the target turnout located ahead of the train, the method further includes:

[0074] In the case where the turnout type is not a crossover turnout, determining whether the turnout is within the movement authorization range;

[0075] When the turnout is within the movement authorization range, calculating the target degraded path end point of the train based on the turnout lock state on the turnout, the resource lock state on the turnout, and the state of the platform parking area of ​​the train;

[0076] When the switch is not within the movement authorization range, the target degraded path end point of the train is calculated based on the switch lock state on the switch and the resource lock state on the switch.

[0077] In this embodiment, when the turnout type is not a crossover turnout, two situations are processed according to the authorized range of movement of the train: crossing the turnout and not crossing the turnout.

[0078] Specifically, the resource lock of the turnout refers to the lock in the turnout used to authorize the train to pass through the turnout corresponding to the turnout lock. For example, when the resource lock belongs to train A or is a public resource, train A can pass through the turnout corresponding to the resource lock. When the resource lock does not belong to train A or is not a public resource, train A cannot pass through the turnout corresponding to the resource lock.

[0079] In this step, refer to Figure 2, when the turnout is in the authorized movement range, determine the switch lock status at the two positions before and after P1 and P2 on the turnout, the resource lock status on the turnout corresponding to the switch locks at the two positions before and after P1 and P2 on the turnout, and the status of the platform parking area of ​​the train. When the switch locks are all in the positioning state, the resource locks are all authorized to the train, and the platform parking area of ​​the train is in an idle state, the parking end of the platform parking area is used as the target downgrade path end of the train, that is, the J4 axle counting position.

[0080] In addition, when the switch locks are all in the positioning state, the resource locks are all authorized to the train, and the platform parking area of ​​the train is not in an idle state, the end point of the mobile authorization range is used as the target degradation path end point of the train.

[0081] In another application scenario, refer to Figure 3 When the turnout is not within the authorized movement range, there are three situations:

[0082] First: When the switch locks P1 and P2 on the switch are both in the positioning state, and the resource lock on the switch corresponding to the switch lock P1 at the position closest to the train is not authorized to the train, the protection point at the switch closest to the train is taken as the target degradation path end point of the train, that is, the J1 axle counting point;

[0083] Second: When the turnout lock P1 on the turnout is in the reverse state and the resource lock on the turnout corresponding to the turnout lock P1 at the position closest to the train is not authorized to the train, the protection point at the turnout at the position closest to the train is taken as the target degradation path end point of the train, that is, the J1 axle counting point;

[0084] Third: When the switch lock P1 on the switch is in the positioning state and the switch lock P2 is in the reverse state, the protection point at the switch closest to the train will be used as the target degradation path end point of the train, that is, the J1 axle counting point.

[0085] Therefore, in this embodiment, different target degradation path endpoint calculations are performed according to different conditions of the turnouts ahead of the train, thereby improving the safety of the train degradation operation and avoiding affecting the subsequent train operation.

[0086] Further, based on the above embodiment, in order to avoid the calculated movement authorization range of the train being inconsistent with the actual movement authorization range of the train, the target degradation path end point of the train is calculated according to the movement authorization range and the platform parking area, including:

[0087] Determining whether the mobile authorization scope is valid;

[0088] When the movement authorization range is valid, the target degradation path end point of the train is calculated according to the movement authorization range and the platform parking area.

[0089] In this step, after the movement authorization range is obtained, if the block section or route section within the movement authorization range of the train is occupied, the movement authorization range is determined to be invalid, otherwise the movement authorization range is determined to be valid.

[0090] Therefore, when the movement authorization range is valid, the target downgrade path end point of the train is calculated based on the positional relationship between the movement authorization range and the platform parking area, thereby ensuring that the train can continue to run safely and automatically to the target downgrade path end point.

[0091] Furthermore, in another application scenario, in order to ensure that a sufficiently large range of safe downgraded operating distance is reserved, in this embodiment, after calculating the target downgrade path end point of the train based on the currently valid movement authorization range, a historical movement authorization range among several valid historical movement authorization ranges is obtained, and the end point of the historical movement authorization range is located in front of the train's running direction and closest to the train's position. If the calculated target downgrade path end point is within the historical movement authorization range, the end point of the historical movement authorization range is used as the train's latest target downgrade path end point, thereby giving the train a longer downgraded operating route, thereby ensuring that the train can automatically decelerate and run to the end of the path more smoothly.

[0092] Furthermore, in another application scenario, if the train has been unable to obtain a valid mobile authorization range, the train's location information is obtained. If the train's minimum safety position and the train's maximum safety position calculated based on the train's location information are on the same platform, the end point of the platform parking area is used as the end point of the downgrade target downgrade path.

[0093] Further, in another embodiment, after determining whether the mobile authorization range is valid, the method further includes:

[0094] In the case where the movement authorization range of the train is invalid, determining whether there is a valid target historical movement authorization range for the train;

[0095] In the case that there is a valid target historical movement authorization range for the train, a target degradation path end point of the train is calculated based on the target historical movement authorization range.

[0096] Specifically, the valid target historical movement authorization range refers to a range in which the end point of the historical movement authorization range among several valid historical movement authorization ranges is located in front of the train running direction and is closest to the train position.

[0097] In this step, when there is a target historical movement authorization range, the end point of the target historical movement authorization range is used as the target degradation path end point of the train.

[0098] Therefore, in this embodiment, when the train cannot obtain a valid movement authorization range after entering the degraded mode, the effective target historical movement authorization range is promptly used to perform degraded operation control on the train, thereby ensuring that the train can be stopped within the safe range of the operating line, thereby avoiding accidents such as collisions with the train ahead.

[0099] The train degradation operation device provided by the present invention is described below. The train degradation operation device described below and the train degradation operation method described above can be referred to each other.

[0100] refer to Figure 4 , Figure 4 Schematic diagram of the structure of the train downgrade operation device provided by the present invention. Figure 4 As shown, the train degradation operation device includes: a first calculation unit 410, which is used to determine the movement authorization range of the train and the platform parking area of ​​the train when the train enters the degradation mode, and calculate the target degradation path end point of the train according to the movement authorization range and the platform parking area; a second calculation unit 420, which is used to obtain the operation parameters of the train, and calculate the buffer time of the train according to the operation parameters of the train and the target degradation path end point; a control unit 430, which is used to control the train to stop at the target degradation path end point when no control instruction carrying the artificial degradation path end point is received within the buffer time.

[0101] Furthermore, the first calculation unit 410 is further configured to use, when the platform parking area is within the movement authorization range, an end point of the movement authorization range as an end point of the target degradation path of the train.

[0102] Furthermore, the first calculation unit 410 is also used to determine the turnout type of the target turnout located in front of the train when the platform parking area is not within the movement authorization range; when the turnout type is a crossing turnout, determine the state of the target turnout lock on the crossing turnout that is closest to the train; when the target turnout lock is in a reverse position and the train does not meet the reverse position requirement of passing through the target turnout lock, use the first target protection point on the crossing turnout that is closest to the train as the target degradation path end point of the train.

[0103] Furthermore, the first calculation unit 410 is also used to determine whether the turnout is within the movement authorization range when the turnout type is not a crossing turnout; when the turnout is within the movement authorization range, calculate the target degraded path endpoint of the train based on the turnout lock status on the turnout, the resource lock status on the turnout and the status of the platform parking area of ​​the train; when the turnout is not within the movement authorization range, calculate the target degraded path endpoint of the train based on the turnout lock status on the turnout and the resource lock status on the turnout.

[0104] Furthermore, the first calculation unit 410 is also used to determine whether the movement authorization range is valid; if the movement authorization range is valid, the target degradation path end point of the train is calculated according to the movement authorization range and the platform parking area.

[0105] Furthermore, the first calculation unit 410 is also used to determine whether the train has a valid target historical movement authorization range when the movement authorization range of the train is invalid; and to calculate the target degradation path endpoint of the train based on the target historical movement authorization range when the train has a valid target historical movement authorization range.

[0106] Furthermore, the control unit 430 is further configured to control the train to stop at the end of the artificial degradation path when a control instruction carrying the end of the artificial degradation path is received within the buffer time.

[0107] The train degradation operation device provided by the present invention determines the movement authorization range of the train and the platform parking area of ​​the train when the train enters the degradation mode, and calculates the target degradation path end point of the train according to the movement authorization range and the platform parking area; obtains the operation parameters of the train, and calculates the buffer time of the train according to the operation parameters of the train and the target degradation path end point; if no control instruction carrying the artificial degradation path end point is received within the buffer time, the train is controlled to stop at the target degradation path end point, thereby the present invention calculates the buffer time between the target degradation path end point and the train arriving at the target degradation path end point, and controls the train to continue to safely and automatically run to the path end point according to the issuance of the control instruction within the buffer time, thereby not only saving labor costs and time costs, but also avoiding affecting the subsequent train operation.

[0108] Figure 5 An example of a physical structure diagram of an electronic device is shown in FIG. Figure 5As shown, the electronic device may include: a processor 510, a communication interface 520, a memory 530 and a communication bus 540, wherein the processor 510, the communication interface 520 and the memory 530 communicate with each other through the communication bus 540. The processor 510 may call the logic instructions in the memory 530 to execute the train degradation operation method, which includes: when the train enters the degradation mode, determining the movement authorization range of the train and the platform parking area of ​​the train, and calculating the target degradation path end point of the train according to the movement authorization range and the platform parking area; obtaining the operation parameters of the train, and calculating the buffer time of the train according to the operation parameters of the train and the target degradation path end point; and controlling the train to stop at the target degradation path end point when no control instruction carrying the artificial degradation path end point is received within the buffer time.

[0109] In addition, the logic instructions in the above-mentioned memory 530 can be implemented in the form of a software functional unit and can be stored in a computer-readable storage medium when it is sold or used as an independent product. Based on such an understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art or the part of the technical solution, can be embodied in the form of a software product, and the computer software product is stored in a storage medium, including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the method described in each embodiment of the present invention.
