Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to a train data transmission method, apparatus, equipment and medium compatible with ground equipment. Background Technology

[0002] In the history of urban rail transit technology development, ground equipment has evolved from ZC (Zone Controller) to... The original ZC / CI (Computer Interlocking) system was transformed into the LCS (Localized Control System). ZC / CI calculates movement authorizations for the onboard ATP (Automatic Train Protection) through interactive route information, protecting train operation. Later, to reduce operating costs and improve efficiency, ZC / CI was integrated into the LCS, and correspondingly, onboard equipment is equipped with either LCS or ZC interface functionality.

[0003] To adapt to different ground equipment, on-board equipment is developed accordingly. However, if the train operates across regions and both sides of the region are equipped with ZC / CI or LCS equipment, the train may be unable to connect to the takeover equipment in the overlapping area, making it impossible to hand over the train.

[0021] The above and / or additional aspects and advantages of this application will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein: Figure 1 This is a flowchart of a train data transmission method compatible with ground equipment provided according to an embodiment of this application; Figure 2 This is a schematic diagram illustrating the principle of a train data transmission method compatible with ground equipment according to an embodiment of this application; Figure 3 This is a block diagram of a train data transmission device compatible with ground equipment provided according to an embodiment of this application; Figure 4 This is a schematic diagram of the structure of an electronic device provided according to an embodiment of this application. Detailed Implementation

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0023] The following description, with reference to the accompanying drawings, outlines a train data transmission method, apparatus, device, and medium compatible with ground equipment according to embodiments of this application. Addressing the problem mentioned in the background art where trains operating across regions with different ground equipment on both sides of the region face difficulties in connecting to ground takeover equipment, leading to train handover issues and reduced operational efficiency, this application provides a train data transmission method compatible with ground equipment. In this method, by obtaining the equipment type of the ground equipment, and when the equipment type is LCS, it determines whether the ZC and / or CI functional modules in the onboard ATP equipment meet a preset first connection condition. If the ZC and / or CI functional modules in the onboard ATP equipment meet the preset first connection condition, a first communication request is sent to the ground adaptation module through the ZC and / or CI functional modules, and data transmission is performed through a first communication channel opened by the ground adaptation module based on the first communication request. This solves the problem of difficulty in achieving compatibility when trains operate across regions with different ground equipment on both sides, leading to train handover issues and reduced operational efficiency. This invention can achieve seamless cross-regional operation compatible with different ground equipment.

[0024] Specifically, Figure 1 This is a schematic flowchart illustrating a train data transmission method compatible with ground equipment, provided in an embodiment of this application.

[0025] like Figure 1 As shown, the train data transmission method compatible with ground equipment includes the following steps: In step S101, the equipment type of the ground equipment is obtained.

[0026] The equipment types for ground equipment include one or more of the following: LCS type, ZC type, and CI type.

[0027] It should be noted that, in order to ensure interoperability to the greatest extent possible, this embodiment of the invention does not modify the structure of the vehicle-mounted electronic map, but only modifies the configuration method of the electronic map. If the ground equipment is LCS, then the ZC / CI of the track segment will be configured as LCS. If the ground equipment is ZC and CI respectively, the original configuration will be maintained, and the ZC / CI of the track segment will be configured respectively.

[0028] In step S102, when the device type is LCS, it is determined whether the ZC function module and / or CI function module in the vehicle-mounted ATP device meet the preset first connection conditions.

[0029] The preset first connection condition can be pre-set by relevant personnel.

[0030] In step S103, if the ZC function module and / or CI function module in the vehicle-mounted ATP device meet the preset first connection conditions, the ZC function module and / or CI function module send a first communication request to the ground adapter module, and the ground adapter module transmits data through the first communication channel opened based on the first communication request.

[0031] It should be noted that, in order to ensure that the train can be better compatible with LCS, ZC, and CI and improve the reusability of software code, the communication protocols of the three have been unified, and a ground adaptation module has been added to the train software to provide an entry point for the original ZC / CI functional modules.

[0032] Specifically, if the ground equipment is an LCS, when the ZC function module / CI function module in the vehicle-mounted ATP determines that the conditions for connecting to the LCS are met, the ZC function module / CI function module submits a communication request to the ground adaptation module to establish communication with the LCS. If the ground adaptation module determines that either the ZC function module or the CI function module has a communication request, it opens the communication channel with the LCS and waits for data to be sent by both parties.

[0033] Additionally, when the train needs to disconnect from ground equipment, if the ground equipment is an LCS (Local Control System), the ZC / CI function module in the onboard ATP (Automatic Train Protection) determines that the conditions for disconnecting the LCS are met, and submits a request to the ground adaptation module to disconnect communication with the LCS. The ground adaptation module only disconnects the channel with the LCS when it determines that both the ZC and CI function modules have submitted disconnect communication requests.

[0034] Optionally, in some embodiments, data transmission is performed through a first communication channel opened by the ground adaptation module based on the first communication request, including: when the ground adaptation module receives application data sent by the ZC function module or the CI function module, forwarding the application data sent by the ZC function module or the CI function module to a preset security protocol layer; when the ground adaptation module simultaneously receives application data sent by the ZC function module and application data sent by the CI function module, determining the largest sequence number among the non-default sequence numbers in the ZC function module and the CI function module, integrating the largest sequence number into the application data sent by the ZC function module and the application data sent by the CI function module, and sending the integrated application data to the preset security protocol layer.

[0035] It should be noted that the software ground adaptation module provides application data receiving and sending functions for the original ZC / CI functional modules. In order to ensure compatibility with LCS / ZC / CI at the same time, the ZC / CI functional modules need to maintain their own serial numbers to ensure the timeliness of the corresponding application data.

[0036] Specifically, if the ground equipment is an LCS device, after the ground adaptation module receives the application data sent by the ZC function module / CI function module, it integrates the application data into a single application data packet and sends it to the LCS. If the ground adaptation module receives only data from the ZC function module or the CI function module, it directly forwards the data to the security protocol layer. If the ground adaptation module receives application data from both the ZC and CI function modules, it retains the largest non-default sequence number from both modules, integrates this sequence number into the data packet, and forwards it to the security protocol layer.

[0037] Optionally, in some embodiments, data transmission is performed through a first communication channel opened by the ground adaptation module based on the first communication application, including: when the ground adaptation module receives application data from the ground device, splitting the application data into a first type of data and a second type of data, sending the first type of data to the ZC function module, and sending the second type of data to the CI function module.

[0038] Specifically, if the ground device is an LCS device, the ground adaptation module receives the application data of the LCS device from the security protocol layer, splits the data packet into two application data according to the data type, and forwards them to the ZC function module or the CI function module respectively.

[0039] Optionally, in some embodiments, after obtaining the device type of the ground device, the method further includes: when the device type is ZC type and / or CI type, determining whether the ZC function module and CI function module in the vehicle-mounted ATP device meet the preset second connection conditions; if the ZC function module and CI function module in the vehicle-mounted ATP device meet the preset second connection conditions, then a second communication request is sent to the ground adaptation module through the ZC function module, data is transmitted through the second communication channel opened by the ground adaptation module based on the second communication request, and a third communication request is sent to the ground adaptation module through the CI function module, and data is transmitted through the third communication channel opened by the ground adaptation module based on the third communication request.

[0040] The preset second connection conditions can be pre-set by relevant personnel.

[0041] Specifically, if the equipment type of the ground equipment is ZC type and / or CI type, when the ZC / CI function module in the vehicle-mounted ATP determines that the conditions for connecting to ZC / CI are met, it submits a communication request to the ground adaptation module to establish communication with ZC / CI. The ground adaptation module maintains two channel lists separately, immediately opens the communication channels with ZC / CI respectively, and waits for data to be sent by both parties.

[0042] In addition, when the train needs to disconnect from the ground equipment, if the ground equipment is a ZC / CI device, the ZC / CI function module in the onboard ATP determines that the conditions for disconnecting ZC / CI are met, and submits a request to the ground adapter module to disconnect communication with ZC / CI. The ground adapter module immediately disconnects the communication channel corresponding to ZC / CI.

[0043] Optionally, in some embodiments, a second communication request is sent to the ground adaptation module through the ZC function module, and data is transmitted through the second communication channel opened by the ground adaptation module based on the second communication request. A third communication request is sent to the ground adaptation module through the CI function module, and data is transmitted through the third communication channel opened by the ground adaptation module based on the third communication request. This includes: when the ground adaptation module receives application data sent by the ZC function module and / or application data sent by the CI function module, sending the application data sent by the ZC function module and / or application data sent by the CI function module to a preset security protocol layer.

[0044] Specifically, in combination Figure 2 As shown, if the ground is a ZC / CI device, after the ground adaptation layer receives the application data sent by the ZC or CI function module, it cancels the data integration operation and directly forwards the application data to the security protocol layer.

[0045] Optionally, in some embodiments, a second communication request is sent to the ground adaptation module through the ZC function module, and data is transmitted through the second communication channel opened by the ground adaptation module based on the second communication request. A third communication request is sent to the ground adaptation module through the CI function module, and data is transmitted through the third communication channel opened by the ground adaptation module based on the third communication request. This includes: when the ground adaptation module receives application data from the ground device, forwarding the application data of the ZC type ground device to the ZC function module, and / or forwarding the application data of the CI type ground device to the CI function module.

[0046] Specifically, if the ground device is a ZC / CI device, after the ground adaptation module receives the ZC or CI application data from the security protocol layer, it directly forwards it to the corresponding ZC function module or CI function module.

[0047] To enable those skilled in the art to further understand the train data transmission method compatible with ground equipment according to the embodiments of the present invention, a detailed description is provided below with reference to specific embodiments. When vehicle-mounted equipment is used in conjunction with ground-based LCS or ZC / CI equipment for cross-regional operation, a handover of control to the ground equipment is required. Details are as follows: When operating across regions, if the ground equipment is only an LCS device or a ZC / CI device, the data interaction method between the onboard ATP and the LCS device or ZC / CI device can adopt the train data transmission method compatible with ground equipment according to the embodiments of the present invention.

[0048] When operating across regions, if the ground equipment is equipped with both LCS and ZC / CI devices, the onboard ATP will operate at the cross-regional boundary according to the following principles: When the train moves from the LCS control area to the ZC control area, or vice versa, the ground takeover device ID is determined based on ground LCS / ZC, ATS, or electronic map information. The onboard unit then searches for the corresponding ground device type (LCS or ZC type) for that device ID. The ZC function module initiates a communication request to the ground adaptation module to establish communication with that LCS / ZC and sends data, while simultaneously reporting the device type to the ground adaptation module. Upon receiving the communication request, the ground adaptation module opens the corresponding channel and directly forwards the data to the safety protocol layer, while recording the ground device type. Upon receiving the data from the safety protocol layer, the ground adaptation module parses the data packet header to determine the source device number and ground device type. If the ground type is an LCS device, parsing continues, and data belonging to the ZC function module is forwarded to the ZC function module. If the ground type is a ZC device, parsing stops, and the entire data packet is forwarded to the ZC function module.

[0049] According to the train data transmission method compatible with ground equipment proposed in this application, by obtaining the equipment type of the ground equipment, when the equipment type is LCS type, it is determined whether the ZC function module and / or CI function module in the on-board ATP equipment meet the preset first connection condition. If the ZC function module and / or CI function module in the on-board ATP equipment meet the preset first connection condition, a first communication request is sent to the ground adaptation module through the ZC function module and / or CI function module, and data transmission is performed through the first communication channel opened by the ground adaptation module based on the first communication request. This solves the problem that when trains operate across regions and different ground equipment is installed on both sides of the region, it is difficult to achieve compatibility, leading to train handover difficulties and reduced operating efficiency. This invention can be compatible with different ground equipment, achieving seamless cross-regional operation.

[0050] Next, with reference to the accompanying drawings, a train data transmission device compatible with ground equipment according to an embodiment of this application is described.

[0051] Figure 3 This is a block diagram of a train data transmission device compatible with ground equipment according to an embodiment of this application.

[0052] like Figure 3As shown, the train data transmission device 10 compatible with ground equipment includes: an acquisition module 100, a judgment module 200, and a transmission module 300.

[0053] The acquisition module 100 is used to acquire the equipment type of the ground equipment.

[0054] The judgment module 200 is used to determine whether the ZC function module and / or CI function module in the vehicle-mounted ATP device meet the preset first connection conditions when the device type is LCS type.

[0055] The transmission module 300 is used to send a first communication request to the ground adapter module through the ZC function module and / or CI function module when the preset first connection conditions are met, and to transmit data through the first communication channel opened by the ground adapter module based on the first communication request.

[0056] Optionally, in some embodiments, after obtaining the device type of the ground device, the acquisition module 100 further includes a judgment unit and a transmission unit.

[0057] The judgment unit is used to determine whether the ZC function module and CI function module in the vehicle-mounted ATP device meet the preset second connection conditions when the device type is ZC type and / or CI type.

[0058] The transmission unit is used to send a second communication request to the ground adapter module through the ZC function module when the ZC function module and CI function module in the vehicle-mounted ATP device meet the preset second connection conditions, and to transmit data through the second communication channel opened by the ground adapter module based on the second communication request, and to send a third communication request to the ground adapter module through the CI function module, and to transmit data through the third communication channel opened by the ground adapter module based on the third communication request.

[0059] Optionally, in some embodiments, the transmission module 300 includes: a first forwarding unit and a second forwarding unit.

[0060] The first forwarding unit is used to forward the application data sent by the ZC function module or the application data sent by the CI function module to a preset security protocol layer when the ground adaptation module receives the application data sent by the ZC function module or the application data sent by the CI function module.

[0061] The second forwarding unit is used to determine the maximum sequence number among the non-default sequence numbers in the ZC and CI functional modules when the ground adaptation module simultaneously receives application data sent by the ZC functional module and application data sent by the CI functional module, integrate the maximum sequence number into the application data sent by the ZC functional module and the application data sent by the CI functional module, and send the integrated application data to the preset security protocol layer.

[0062] Optionally, in some embodiments, the transmission module 300 includes a sending unit.

[0063] The sending unit is used to split the application data into a first type of data and a second type of data when the ground adaptation module receives the application data from the ground equipment, and send the first type of data to the ZC function module and the second type of data to the CI function module.

[0064] Optionally, in some embodiments, the transmission unit includes: a first transmitting subunit.

[0065] The first transmitting subunit is used to transmit the application data sent by the ZC function module and / or the application data sent by the CI function module to a preset security protocol layer when the ground adaptation module receives the application data sent by the ZC function module and / or the application data sent by the CI function module.

[0066] Optionally, in some embodiments, the transmission unit includes a second transmitting subunit.

[0067] The second transmitting subunit is used to forward the application data of the ZC type ground equipment to the ZC function module and / or forward the application data of the CI type ground equipment to the CI function module when the ground adaptation module receives the application data of the ground equipment.

[0068] It should be noted that the foregoing explanation of the train data transmission method embodiment for compatible ground equipment also applies to the train data transmission device for compatible ground equipment in this embodiment, and will not be repeated here.

[0069] According to the train data transmission device compatible with ground equipment proposed in this application embodiment, by obtaining the equipment type of the ground equipment, when the equipment type is LCS type, it determines whether the ZC function module and / or CI function module in the on-board ATP equipment meet the preset first connection condition. If the ZC function module and / or CI function module in the on-board ATP equipment meet the preset first connection condition, a first communication request is sent to the ground adaptation module through the ZC function module and / or CI function module, and data transmission is performed through the first communication channel opened by the ground adaptation module based on the first communication request. This solves the problem that when trains operate across regions and different ground equipment is installed on both sides of the region, it is difficult to achieve compatibility, leading to train handover difficulties and reduced operating efficiency. This invention can be compatible with different ground equipment, achieving seamless cross-regional operation.
