[0030] Firstly, the related terms involved in the present application are introduced.

[0031] CBTC (Communication Based Train Control System, train automatic control system based on communication): a train operation control system based on communication technology.

[0032] Please refer to Figure 1 , Figure 1 is a structure block diagram of a section occupancy detection system of a train provided by an embodiment of the present application. As shown in Figure 1 , the section occupancy detection system 10 of the train includes: a vehicle-mounted control system 110, a target wireless access point 120, a wireless controller 130, and a ground control server 140.

[0033] Among them, the target wireless access point 120 includes: a first target wireless access point 121 in communication connection with a first data network, and a second target wireless access point 122 in communication connection with a second data network. Specifically, the first data network and the second data network are redundant designs of a train network control system, and the first data network and the second data network form an A / B dual-network system. When communicating normally, the A / B dual-network simultaneously transmits data to related equipment and interacts consistent data. When one side of the network is paralyzed or a communication failure occurs, the other side of the network can normally perform network communication functions, thereby ensuring the safety of train network control.

[0034] Specifically, the wireless access point is a plurality of AP (Access Point, wireless access point) devices installed beside the track, which are used for data interaction. The target wireless access point refers to a wireless access point in communication connection with the train.

[0035] Among them, the vehicle-mounted control system 110 is installed on the train, and the vehicle-mounted control system 110 includes a vehicle-mounted controller 111, a vehicle-mounted AP (A) 112, and a vehicle-mounted AP (B) 113. The vehicle-mounted AP (A) 112 is an AP device for the A communication network in the A / B dual-network for redundant design. Similarly, the vehicle-mounted AP (B) 113 is an AP device for the B communication network in the A / B dual-network for train communication network.

[0036] Specifically, the vehicle-mounted control system 110 can further include an AP switch, which is connected with the vehicle-mounted controller 111, the vehicle-mounted AP (A) 112, and the vehicle-mounted AP (B) 113, respectively, thereby providing more stable and efficient information forwarding interaction.

[0037] Among them, the wireless controller 130 aggregates data information of the first target wireless access point 121 and the second target wireless access point 122, and forwards the data information to the ground control server 140.

[0038] Specifically, the wireless controller 130 and the target wireless access point 120 can adopt optical fiber communication mode, and the ground control server 140 and the wireless controller 130 can adopt Ethernet communication mode.

[0039] A section occupation detection method of a train is introduced below.

[0040] Please refer to Figure 2 , Figure 2 is a flowchart of a section occupation detection method of a train provided by the embodiments of the present application, and the method is applied to a ground control server 140 as shown in Figure 1 includes the following steps:

[0041] Step 210: receiving an identification set from a target wireless access point.

[0042] The target wireless access point includes a first target wireless access point in communication connection with a first data network and a second target wireless access point in communication connection with a second data network, and the identification set includes first identification information, second identification information and third identification information. The first identification information is used to represent the identification information of the first target wireless access point, the second identification information is used to represent the identification information of the second target wireless access point, and the third identification information is used to represent the train identification of the train.

[0043] In one possible example, the target wireless access point is a network device pre-set beside the running track of the train and used to establish a wireless network.

[0044] The target wireless access point is a network device pre-set on both sides of the track, that is, the system does not need to additionally increase hardware devices to detect the train occupation state, and does not need to install an axle counter, thereby reducing the cost of the signal system.

[0045] When the train passes through the target wireless access point, the on-board controller establishes a communication connection with the target wireless access point, the target wireless access point sends the identification information of the first target wireless access point to the on-board AP(A) in the on-board control system, and sends the identification information of the second target wireless access point to the on-board AP(B); and then the target wireless access point forwards the first identification information and the second identification information to the ground control server.

[0046] The third identification information is identification information sent by the on-board controller to the target wireless access point after receiving the first identification information and / or the second identification information of the target wireless access point, and used to represent the identification of the train exclusive equipment. After receiving the third identification information, the target wireless access point forwards the third identification information to the ground control server.

[0047] Specifically, the vehicle-mounted AP (A) in the vehicle-mounted control system is in communication connection with the target wireless access point (B) through a free wave antenna.

[0048] In step 220, when it is determined that the first target wireless access point and the second target wireless access point correspond to the same logical section according to the first identification information and the second identification information, the target logical section corresponding to the first identification information and the second identification information is determined.

[0049] The target logical section is one of a plurality of sections based on a track in a preset manner.

[0050] For example, the logical section is different from a physical section or a track section, and the logical section is a smaller virtual section unit divided in the physical section, and the target logical section is used to represent an area covered by a communication range of the target wireless access point.

[0051] For example, in a normal communication environment, the first data network and the second data network perform data transmission and interact with other devices at the same time, and the data is consistent. When one side of the network is paralyzed or communication failure occurs, the other side of the network can normally perform network communication functions. When the first identification information and the second identification information cannot be determined by consistency, it is determined that the communication between the target wireless access point and the ground control server is abnormal, and the first identification information and the second identification information received are not accepted.

[0052] In step 230, it is determined that the section occupied by the train indicated by the third identification information is the target logical section.

[0053] Specifically, after the ground control server adjusts the target logical section to the occupied state, the ground control server sends the occupied information of the target logical section to other trains at the same time, so as to prompt other trains to the position information of the section where the current train is located.

[0054] For example, according to the third identification information, it is confirmed that the train indicated by the third identification information is in a communication-based train control mode, and the train position of the train is in a lost state. The lost state refers to a state in which the ground control server cannot obtain the train position information. When the train is in the lost state, the train itself also cannot obtain the train position information, and at this time, the train is in a dangerous lost positioning driving state. The ground control server monitors the running conditions of a plurality of trains on a plurality of track lines in real time, and queries the current running condition of the train according to the train identification.

[0055] In one possible example, after determining that the section occupied by the train indicated by the third identification information is the target logical section, the method further includes: receiving other identification information of other wireless access points of any other logical section outside the target logical section, the other wireless access points including: a first other wireless access point connected with the first data network and a second other wireless access point connected with the second data network, the other identification information including: identification information of the first other wireless access point and identification information of the second other wireless access point; when the first other wireless access point and the second other wireless access point correspond to the same logical section according to the identification information of the first other wireless access point and the identification information of the second other wireless access point, determining an updated target logical section corresponding to the other identification information according to the other identification information; and determining that the train occupies the updated target logical section.

[0056] In the application scenario, the train runs through a plurality of wireless access points, and the target wireless access point is the wireless access point currently connected with the train. After the train runs out of the communication coverage of the target wireless access point, the train is connected with other wireless access points. The other logical section refers to the next logical section adjacent to the target logical section based on the current running direction of the train.

[0057] Specifically, after receiving the other identification information, consistency judgment is performed on the other identification information. When the other identification information passes the consistency judgment, the other identification information is accepted, otherwise, the other identification information is deleted and it is determined that the current communication fails.

[0058] Please refer to Figure 3 , Figure 3 is a schematic diagram of a train running application scenario provided by the embodiment of the application, as Figure 3 shown, the target wireless access point 310 includes a first target wireless access point 311 and a second target wireless access point 312; the train 320 is also provided with two corresponding access points for respectively communicating with the access point 311 and the access point 312; and the other wireless access point 330 is a wireless access point currently not connected with the train 320.

[0059] As Figure 3As shown, the arrow indicates the original direction of the train 320, and the train 320 is disconnected with the ground control server after entering the communication coverage of the target wireless access point. At this time, the train 320 is connected with the target wireless access point 310, and the identification information of the access points 311 and 312 is sent to the train 320 through the access points 311 and 312. After the train 320 confirms, the train identification is sent to the target wireless access point 310. The logical section of the communication coverage of the target wireless access point 310 is determined as the occupied state by the ground control server, and the train 320 can also determine the position information according to the identification information of the target wireless access point 310.

[0060] Specifically, when the train 320 runs to the intersection area of the communication coverage of the target wireless access point 310 and other wireless access points 330, as shown in the middle area 340, the wireless controller analyzes and determines to switch the wireless access point, that is, the wireless controller determines to keep connected with the target wireless access point 310 or to disconnect with the target wireless access point 310 and to connect with other wireless access points 330. Similarly, after the other wireless access points 330 are connected, the ground control server determines the logical section of the communication coverage of the other wireless access points 330 as the occupied state. Figure 3

[0061] It can be seen that in the present example, by receiving other identification information of other wireless access points, the other wireless access points refer to at least one wireless access point other than the target wireless access point, the other logical section corresponding to the other identification information is determined according to the other identification information, the other logical section is set as the occupied state, and the occupied state of the target logical section is cancelled. According to the communication with the other wireless access points, the train position information is updated, which is beneficial to improve the real-time and intelligence of the occupied state detection of the train.

[0062] In one possible example, the ground control server is connected with the wireless controller, the wireless controller is connected with a plurality of wireless access points, and the information sent by the plurality of wireless access points is summarized by the wireless controller. After determining that the train-occupied section indicated by the third identification information is the target logical section, the method further comprises: monitoring the first communication state between the ground control server and the wireless controller every first monitoring period; if the monitoring result indicates that the communication between the ground control server and the wireless controller is interrupted, determining that the occupied detection fails, and generating a prompt information, the prompt information is used to indicate that the track maintenance personnel intervenes to protect the operation of the train.

[0063] ​When it is determined that the ground control server and the wireless controller are in communication failure, the occupancy device failure is determined, wherein the occupancy device refers to a plurality of devices for detecting the train occupancy state. At this time, the train is in a situation where communication and positioning are impossible, and the track line maintenance personnel needs to be notified for manual intervention to protect the train operation and avoid traffic accidents. The first monitoring period is a preset monitoring period, which can be 5 minutes, 10 minutes, or other lengths, without limitation.

[0064] Specifically, when the first communication state of the ground control server and the wireless controller is not in the communication interruption state, but the quality of the first communication state is insufficient to meet the interaction of normal train positioning related information, the track line maintenance personnel is also notified to protect the train operation.

[0065] In other possible examples, the wireless access points of the entire line can also be directly connected in communication with the ground control server, without the need for the wireless controller to aggregate and forward information to the ground control server.

[0066] As can be seen, in the present example, the first communication state between the ground control server and the wireless controller is monitored every first monitoring period. If the monitoring result indicates that the communication between the ground control server and the wireless controller is interrupted, the occupancy detection failure is determined, and the track maintenance personnel is instructed to intervene to protect the train operation, which is beneficial to protect the safe operation of the train in the case of communication failure between the ground control server and the wireless controller, and improves the reliability of the train occupancy state detection.

[0067] In one possible example, after determining that the train occupancy section indicated by the third identification information is the target logical section, the method further comprises: monitoring the second communication state between the wireless controller and the plurality of wireless access points every second monitoring period; if the monitoring result indicates that the communication between the wireless controller and at least one wireless access point of the plurality of wireless access points is interrupted, performing failure processing on the at least one wireless access point that has communication interruption with the wireless controller to solve the abnormal problem of the second communication state.

[0068] The wireless controller aggregates information of the plurality of wireless access points and communicates with the wireless access points installed on the entire line every second monitoring period. If the communication between any wireless access point and the wireless controller is interrupted, the wireless controller forwards the communication failure information to the ground control server, and the ground control server performs safety processing for the communication failure. The second monitoring period is a preset monitoring period, and the second monitoring period and the first monitoring period are independent of each other.

[0069] It can be seen that in the example, by monitoring the second communication state between the wireless controller and the plurality of wireless access points every second monitoring period, if the monitoring result indicates that the communication between the wireless controller and at least one wireless access point of the plurality of wireless access points is interrupted, the at least one wireless access point which has communication interruption with the wireless controller is processed for fault handling, the problem of abnormal second communication state is solved, the communication fault between the wireless access point and the wireless controller is processed in time, which is beneficial to improve the reliability of the train position information interaction and strengthen the stability of the train occupation detection.

[0070] In one possible example, after determining that the section occupied by the train indicated by the third identification information is the target logical section, the method further includes: receiving fault information sent from the target wireless access point, the fault information being used to indicate that the third communication state between the target wireless access point and the on-board controller of the train is in an abnormal state; and performing fault handling on the target wireless access point and the on-board controller to solve the abnormal problem of the third communication state.

[0071] The ground control server aggregates the communication fault information between the wireless access point and the on-board controller, and performs fault handling according to the fault information, so as to ensure stable communication during train operation.

[0072] It can be seen that in the example, by receiving the fault information sent from the target wireless access point, the fault information being used to indicate that the third communication state between the target wireless access point and the on-board controller of the train is in an abnormal state, fault handling is performed on the target wireless access point and the on-board controller to solve the abnormal problem of the third communication state, which improves the reliability and stability of the train occupation detection.

[0073] In one possible example, determining the target logical section corresponding to the first identification information and the second identification information includes: taking the first identification information or the second identification as a query identification, querying a preset section set to obtain the target logical section corresponding to the first identification information or the second identification information, and the section set includes a corresponding relationship between the identification information and the logical section.

[0074] In other possible examples, after the on-board controller receives the first identification information and / or the second identification information, the logical section in which the train is located is also confirmed according to the section set, and the position range of the train lost positioning is determined according to the logical section.

[0075] For example, refer to Figure 4 , Figure 4 is a specific flowchart of a train section occupation detection method provided by the embodiment of the present application, which includes the following steps:

[0076] 41. The on-board AP sends a communication request to the target wireless access point.

[0077] Wherein, the target wireless access point and the wireless controller are essentially an integral access system, and the wireless controller controls the communication-related functions of all wireless access points on the route in actual application.

[0078] Wherein, the target wireless access point receives the communication request sent by the on-board AP, reports the request to the wireless controller, and replies to the communication request through the wireless controller.

[0079] 42. The on-board AP receives the reply information and forwards the reply information to the on-board controller.

[0080] Wherein, the reply information includes the identification information of the target wireless access point; specifically, an AP switch can also be included between the on-board AP and the on-board controller.

[0081] 43. The on-board controller receives the reply information and sends the train identification to the target wireless access point through the on-board AP.

[0082] Specifically, the on-board AP can forward its own on-board AP identification information to the target wireless access point.

[0083] 44. The on-board controller receives the reply information, determines the logical section corresponding to the target identification information according to the preset section set, and locates the position information of the train according to the logical section.

[0084] 45. The wireless controller aggregates the information of the target wireless access point and forwards the information set containing the train identification information and the identification information of the target wireless access point to the ground control server.

[0085] 46. The ground control server determines the corresponding logical section by comparing the received train identification and the identification information of the target wireless access point with the preset section set, and sets the logical section to an occupied state.

[0086] Wherein, the ground control server sets the logical section to an occupied state to realize occupancy detection.

[0087] 47. The ground control server sends the occupancy information of the logical section to other trains.

[0088] Wherein, the other trains refer to the trains controlled by the ground control server, and the ground control server synchronizes the occupancy information of the logical section to multiple other trains to ensure that the other trains will not enter the logical section at the current time, thereby avoiding traffic accidents.

[0089] In one possible example, after determining that the state of the target logical section is the occupied state indicated by the third identification information, the method further comprises: comparing the positioning position of the train with the corresponding logical section determined according to the first identification information and / or the second identification information every third monitoring period; if the positioning position information is consistent with the logical section, it is determined that the positioning position and the logical section are correct; if the positioning position information is inconsistent with the logical section, it is determined that the identification information of the on-board wireless access point of the train is configured incorrectly.

[0090] It can be seen that, by implementing the embodiment of the present application, the ground control server first receives an identification set from a target wireless access point, the identification set including first identification information, second identification information and third identification information, and then determines the target logical section corresponding to the first identification information and the second identification information based on the consistency voting of the first identification information and the second identification information, so as to determine that the section occupied by the train indicated by the third identification information is the target logical section. Through the communication interaction between the ground control server and the wayside wireless access point, the train occupancy state detection is performed, which solves the problems of poor stability and large result error of train occupancy detection in the prior art, and at the same time, without the need for additional installation of hardware detection equipment, the labor cost is saved, the accuracy of train section occupancy detection is improved, the safety driving demand in the train running process is ensured, and the stability of train occupancy detection is improved.

[0091] Please refer to Figure 5 , Figure 5 is a flow diagram of another train section occupancy detection method provided by the embodiment of the present application, and the method is applied to the on-board controller 111 as shown in Figure 1 , and includes the following steps:

[0092] Step 510, receiving an identification set from a target wireless access point through an on-board wireless access point.

[0093] The target wireless access point includes a first target wireless access point in communication connection with a first data network and a second target wireless access point in communication connection with a second data network, and the identification set includes first identification information, second identification information and third identification information, wherein the first identification information is used to represent the identification information of the first target wireless access point, and the second identification information is used to represent the identification information of the second target wireless access point.

[0094] Step 520, when it is determined that the first target wireless access point and the second target wireless access point correspond to the same logical section according to the first identification information and the second identification information, determining the target logical section corresponding to the first identification information and the second identification information.

[0095] The target logical section is one of a plurality of sections based on a preset track division.

[0096] Step 530, determining that the train position is in the target logical section.

[0097] Wherein, the on-board controller of the train determines the train position range according to the information sent by the on-board wireless access point, and the range determined by it is the target logical section.

[0098] In one possible example, determining that the first target wireless access point and the second target wireless access point correspond to the same logical section according to the first identification information and the second identification information includes: performing consistency voting on the first identification information and the second identification information; when the first identification information is consistent with the second identification information, then determining the logical section corresponding to the first identification information and / or the second identification information according to the first identification information and / or the second identification information.

[0099] Wherein, due to the redundant design of the AB double-network of the train track network, the wireless access points are presented in pairs, and the identification information of the wireless access points corresponding to the A data network and the B data network is consistent under normal circumstances, therefore, the consistency voting refers to judging whether the two received wireless access points are consistent, if the wireless identification of the two wireless access points is consistent, then it is determined that the consistency voting is passed; otherwise, it is not passed, indicating that there is a fault in the AB data network communication, and the data is not used.
