Description

Technical Field

[0001] The present invention relates to a train signal control system, and in particular to a train resource re-education system, method, equipment and medium based on train control right switching. Background Art

[0002] As a new generation of train control system, vehicle-to-vehicle communication mainly includes a car-mounted controller (CC: Carbon Controller), a trackside train controller (WTC: Wayside Train Controller) and a trackside resource controller (WRC: Wayside Resources Controller). The car-mounted controller CC or the trackside train controller WTC calculates the train's running trajectory, and the trackside resource controller WRC completes resource allocation and monitoring.

[0003] After searching, Chinese patent publication number CN115571198A discloses a train control authority switching method and system based on vehicle-to-vehicle communication, which specifically discloses the following: Step A: After the train starts, the main controller on-board train controller controls the train, and at this time the trackside train controller monitors the positioning status and communication status of the on-board train controller; Step B: The trackside train controller generates a control authority switching request authority_request according to the positioning status and communication status of the on-board train controller; Step C: If the authority_request status is different from that of the previous cycle, the trackside resource controller cuts off the control authority of the trackside train controller and the on-board train controller, and the train is in a state of no controller control; Step D: The trackside resource controller records the current time as T_(authority_request), and if the authority_request status does not change within the set period, the trackside resource controller grants the train control authority to the trackside train controller. That is, in the existing vehicle-to-vehicle communication system, it is possible to complete switching between the on-board controller and the trackside train controller to achieve redundant control of the train, but it is impossible to transfer train resources between the two train controllers. Therefore, how to solve the problem of re-education after the control of the train is switched and avoid the loss of train resources, thereby improving the stability of the system, has become a technical problem that needs to be solved. Summary of the invention

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] According to a first aspect of the present invention, there is provided a train resource re-education system, which implements train resource re-education after the train control right is switched, the system comprising an onboard controller CC, a trackside train controller WTC and a trackside resource controller WRC, the trackside resource controller WRC being communicatively connected with the onboard controller CC and the trackside train controller WTC respectively;

[0007] The trackside resource controller WRC uses the resource request area sent by the onboard controller CC to determine the re-education area. When the trackside train controller WTC obtains control, the trackside resource controller WRC re-educates the trackside train controller WTC, wherein the re-education means that when the train is switched from the onboard controller CC to the trackside train controller WTC, with the assistance of the trackside resource controller WRC, resources are transferred from the onboard controller CC to the trackside onboard controller WTC.

[0008] As a preferred technical solution, the trackside resource controller WRC and the onboard controller CC perform double checks on train resources.

[0009] According to a second aspect of the present invention, a method using the train resource re-education system is provided, the method comprising the following steps:

[0010] Step S1: The onboard controller CC requests the resource area Z from the trackside resource controller WRC according to the running track. 1 ;

[0011] Step S2: The trackside resource controller WRC calculates the resource area Z according to the request of the vehicle controller CC. 2 , and request the vehicle controller CC to return the resource area Z 3 ;

[0012] Step S3: If the trackside resource controller WRC detects that it is the first time for the vehicle controller CC to request a resource area, that is, M first_request = 0, then the resource area Z 2 Assign value to the heavy education resource area Z 4 , and M first_request Set to 1 and execute step S6; otherwise, the trackside resource controller WRC sets the maximum travel time V of the train in the current area. current_zone and the maximum effective time T of the vehicle controller CC resource request survival_time Get area Z 5 , and execute step S4;

[0013] Step S4: If the resource area Z 2 Included in resource area Z 5 , the trackside resource controller WRC will resource area Z 2Send to the vehicle controller CC and execute step S5; otherwise, execute step S8;

[0014] Step S5, the trackside resource controller WRC calculates the resource area Z 41 =Z 4 +Z 2 -Z 3 , and the resource area Z 41 Assigned to Z as the latest important educational resource area 4 , and execute step S6;

[0015] Step S6, determine whether control right switching occurs. If yes, the trackside resource controller WRC grants control right to the trackside train controller WTC for a period of T authority , and execute step S7; otherwise, return to step S1;

[0016] Step S7: If a re-education request is received from the trackside train controller WTC, and T current_cycle and T authority The difference is less than T max_survival , execute step S8; if no re-education request is received from the trackside train controller WTC, and T current_cycle and T authority The difference is less than T max_survival , return to step 6; if no re-education request is received from the trackside train controller WTC, and T current_cycle and T authority The difference is greater than T max_survival , the trackside resource controller WRC will M first_request is set to 0, and then returns to step S1; wherein T max_survival To allow for a maximum waiting time;

[0017] Step S8, the trackside resource controller WRC immediately re-educates the resource area Z 4 Sent to the train controller.

[0018] As a preferred technical solution, in step S1, it is assumed that the onboard controller CC controls the train to apply for resources. If it is switched to the trackside train controller WTC, the onboard controller CC is replaced by the trackside train controller WTC.

[0019] As a preferred technical solution, in step S1, the resource area requested by the onboard controller CC includes the train travel direction, denoted as direction_1. When the train is stationary and has not received any task, the resource area requested by the onboard controller CC is empty.

[0020] As a preferred technical solution, in step S2, the resource area requested to be returned by the trackside resource controller WRC includes the train direction, denoted as direction_2. If direction_1 and direction_2 are different, the trackside resource controller WRC discards the request of the onboard controller CC.

[0021] As a preferred technical solution, in step S2, the trackside resource controller WRC calculates the area Z 2 The same as the area requested by the onboard controller CC; if the area requested by the onboard controller CC is empty, the area Z calculated by the trackside resource controller WRC 2 Is empty.

[0022] As a preferred technical solution, in step S2, if two trains apply for the same area resources at the same time, the trackside resource controller WRC allocates the resources to the train that applies for the resources first, and then allows the two trains to negotiate the subsequent allocation of resources.

[0023] As a preferred technical solution, in step S3, the trackside resource controller WRC checks M each time. first_request Is it equal to 1? If not, assign the currently calculated area to the education resource area Z. 4 , and M first_request Set to 1.

[0025] The maximum effective time T of the vehicle controller CC resource request survival_time It is the maximum value from the time when the trackside resource controller WRC receives the Nth packet request message to the time when the trackside resource controller WRC receives the N+1th packet request message, and includes the maximum network transmission delay, the onboard controller CC calculation delay, and the trackside resource controller WRC calculation delay.

[0026] As a preferred technical solution, in step S3, when a turnout is encountered during the calculation of the trackside resource controller WRC, the onboard controller CC requests the area Z 1 Determine the turnout location.

[0027] As a preferred technical solution, in step S4, resource area Z 5 Used to achieve reasonable allocation of train resources, beyond resource area Z 5 This means that the train location information is wrong and needs to be directed to the safe side, which means that re-education is needed at this time.

[0028] As a preferred technical solution, in step S7, the re-education request of the trackside train controller WTC must be issued within a specified time.

[0029] As a preferred technical solution, step S8 includes two different situations: if a control right switch occurs, the re-education resource area is sent to the trackside train controller WTC; if the area check fails, it is sent to the on-board controller CC.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0044] The present invention proposes that when the train control is switched from the onboard train controller CC (Carborne Controller) to the trackside train controller WTC (Wayside Train Controller), the train resources are re-educated to avoid the problem of train resource loss and improve the stability of the system. The present invention uses the trackside resource controller WRC (Wayside Resources Controller) and the onboard controller CC to double-check the train resources to increase the reliability of the system. It can achieve the reasonable allocation of train resources, avoid resource waste or unreasonable resource occupation, and improve the operation efficiency. Figure 1 and Figure 2 shown.

[0045] The specific meaning of the re-education of the present invention is: it refers to the process of transferring resources between two controllers of the train through the trackside resource controller WRC. For example, the on-board controller applies for resource area A from the trackside resource controller WRC. At this time, the train switches to the trackside train controller, and the trackside resource controller WRC transmits the resource area A to the trackside train controller.

[0046] like Figure 1 In step 1, the vehicle controller CC requests the resource area Z from the trackside resource controller WRC according to the running track. 1 , Region Z 1 The range is as Figure 3As shown; it is assumed that the onboard controller CC controls the train to apply for resources. If it is switched to the trackside train controller WTC, the onboard controller CC is replaced by the trackside train controller WTC; and when the train is stationary and no new tasks are received, the area applied for by the onboard controller CC may be empty; the area applied for by the onboard controller CC includes the direction of train travel;

[0047] like Figure 2 In step 2, the trackside resource controller WRC calculates the area Z according to the request of the onboard controller CC. 2 ; At the same time, request the vehicle controller CC to return the resource area Z 3 ; The resource area requested to be returned by the trackside resource controller WRC includes the train direction. If the two directions are different, the trackside resource controller WRC will discard the current onboard controller CC request as illegal information; The area Z calculated by the trackside resource controller WRC 2 It is usually the same as the area requested by the onboard controller CC; but the area Z calculated by the trackside resource controller WRC 2 It may be empty, that is, when the vehicle controller CC requests that the area is empty, area Z 2 The range is as Figure 3 As shown; if two trains apply for the same area resources at the same time, the trackside resource controller WRC will allocate the resources to the train that applied for the resources first, and then let the two trains negotiate the subsequent allocation of resources;

[0048] like Figure 2 In step 3, if the trackside resource controller WRC detects that it is the first time for the onboard controller CC to request a resource area, that is, M first_request = 0, then the resource area Z 2 Assign value to the heavy education resource area Z 4 , and M first_request Set to 1, and then go to step 6; otherwise, the trackside resource controller WRC sets the maximum travel time V of the train in the current area. current_zone and the maximum effective time T of the vehicle controller CC resource request survival_time Get area Z 5 , Region Z 5 The range is as Figure 3 As shown; the trackside resource controller WRC will check M every time first_request Is it equal to 1? If not, assign the currently calculated resource area to the heavy education resource area and set M first_request Set to 1; the maximum travel time of the train is V current_zone is the maximum driving speed in the current area, which is affected by the temporary speed limit, permanent speed limit and data configuration speed, and takes the minimum value of the three; the maximum effective time T of the vehicle controller CC resource request survival_timeIt is the maximum value from the time when the trackside resource controller WRC receives the Nth packet request message to the time when it receives the N+1th packet request message. It is necessary to consider the maximum network transmission delay, the calculation delay of the onboard controller CC, and the calculation delay of the resource area by the trackside resource controller WRC. When the trackside resource controller WRC encounters a turnout during the calculation process, the Zth zone is requested according to the onboard controller CC. 1 Determine the turnout location;

[0049] like Figure 2 In step 4 shown, if resource area Z 2 Included in resource area Z 5 , the trackside resource controller WRC will resource area Z 2 Send to the vehicle controller CC; otherwise, go to step 8; where the resource area Z 5 This is to achieve a reasonable allocation of train resources and improve operating efficiency. Exceeding this area indicates that the train position information is wrong and needs to be directed to the safe side, that is, re-education is required at this time;

[0050] like Figure 2 In step 5, the trackside resource controller WRC calculates Z 41 =Z 4 +Z 2 -Z 3 , and the area Z 41 Assigned to Z as the latest important educational resource area 4 , Region Z 4 and region Z 41 Range such as Figure 3 As shown, the trackside resource controller WRC needs to calculate the education resources of this cycle based on the education resources of the previous cycle of the onboard controller CC, the new resources applied for this cycle, and the returned resources; considering that the application of resources in this cycle is to avoid the situation where the education resources cannot cover the actual position of the train due to the sudden loss of communication of the train;

[0051] like Figure 2 If a control right switch occurs in step 6, the trackside resource controller WRC grants the control right to the trackside train controller WTC with a period of T authority ; Otherwise, if the above conditions are not met, go to step 1; the trackside resource controller WRC is responsible for the distribution of control rights and records the control rights distribution cycle T authority It is to monitor the status of train resources and prevent trains from unreasonably occupying resources for a long time;

[0052] like Figure 2 In step 7 shown in FIG. 1 , if a re-education request is received from the trackside train controller WTC, and T current_cycle and T authority The difference is less than T max_survival; Otherwise, if no re-education request is received from the trackside train controller WTC, and T current_cycle and T authority The difference is less than T max_survival , go to step 6; otherwise, if no re-education request is received from the trackside train controller WTC, and T current_cycle and T authority The difference is greater than T max_survival , the trackside resource controller WRC will M first_request Set to 0, and then enter step 1; it requires the re-education request of the trackside train controller WTC to be issued within the specified time to avoid unreasonable occupation of resources; the maximum waiting time allowed is T max_survival Take into account both operational efficiency and safety factors; if the time exceeds T max_survival Reentering step 1 is to ensure that the train position can be updated in the second way. At this time, the trackside train controller WTC applies for resources in the above steps 1 to 5, and checks whether the control right is switched to the onboard controller CC in step 6; and M appears first_request There is only one case where the waiting time exceeds the maximum waiting time T. max_survival ;

[0053] like Figure 1 In step 8 shown in FIG. 1 , the trackside resource controller WRC immediately re-education resource area Z 4 Sent to the train controller; including two different situations: if control switching occurs, the heavy education resource area is sent to the trackside train controller WTC; if the regional inspection fails, it is sent to the on-board controller CC.
