[0002] The CTCS-0 level train control system is designed for sections of 120 km / h and below on existing railways in China, mainly to be compatible with existing railway signal systems. In this system, the basic line data plays a crucial role.

[0003] Due to reasons such as train operation diagram adjustment or line construction, each railway administration group company needs to frequently change the CTCS-0 level basic line data. After the change, it is necessary to replace the data on all locomotives within the jurisdiction. Currently, the main method is manual replacement. Workers carry data transporters and IC cards to replace the data on each train in the depot one by one. The replacement workload is large, the cycle is long, and it is impossible to achieve a one-time comprehensive replacement, and there are risks of missed replacement and wrong replacement.

[0004] In addition, due to reasons such as the storage capacity of on-vehicle CTCS-0 level train control equipment, the CTCS-0 level basic line data pre-stored on the vehicle cannot accommodate all railway data. It only contains all the data of the local railway administration and some data of other railway administrations, and some reverse data of other railway administrations has been deleted. When the train runs in the reverse direction, it can only rely on the train operation management regulations to select the shunting or other modes of operation, and the train cannot operate within the entire railway network.

[0012] According to a preferred embodiment of the present invention, the central data server is specifically configured to, for any station, use the station information of the station in the global basic train line data as the starting information and the station information of each next station of the station as the ending information; obtain the line data between the starting information and each ending information; combine the starting information, the line data, and each ending information to generate the basic train line data of the station corresponding to the station; and generate the basic train line data of the station corresponding to each station respectively.

It should also be understood that although the first, second, third, etc. attributives indicating numbers may be used herein to describe various devices, elements, components, or parts, these devices, elements, components, or parts should not be limited by these attributives. That is to say, these attributives are only used to distinguish one from another. For example, the first device may also be called the second device, but it does not deviate from the technical solution of the present invention. In addition, the terms "and / or", "or / and" mean all combinations including any one or more of the items listed.

[0022] Please refer to Figure 1 , Figure 1 which is one of the schematic flowcharts of a method for distributed deployment of train basic line data provided by the present invention. As Figure 1 shown, the method includes: S11. Compile the train basic line data of each data source to obtain global train basic line data and upload it to the central data server.

[0023] In this embodiment, the train basic line data may be CTCS-0 level basic line data. The CTCS-0 level basic line data is the "electronic map" pre-stored in the CTCS-0 level train control equipment. This data set is compiled according to the line data such as lines, signals, stations, and tracks included in the "Train Operation Diagram Technical Data" of the railway administration group company, and includes the data of this bureau and part of the data of adjacent external bureaus. When the line data changes due to the adjustment of the train operation diagram or line construction, it is necessary to change the CTCS-0 level basic line data and perform data replacement on the CTCS-0 level basic line data pre-stored in the on-vehicle CTCS-0 level train control equipment.

[0024] In this embodiment, the data sources in this solution may be each railway administration company. The train basic line data of each railway administration company is obtained, and then the train basic line data of each train is integrated to obtain global train basic line data.

[0025] Specifically, after each railway administration group company completes data compilation according to the existing CTCS-0 level basic line data compilation management system, the target file generated by compiling the CTCS-0 level basic line data is the 2KDATA.BIN file, and the 2KADATA.BIN target file is uploaded to the central data server. The 2KDATA.BIN file is a binary data file related to the train control system (such as the LKJ system).

[0026] S12. Based on the station information table, the central data server splits the global train basic line data into the station train basic line data corresponding to each station and distributes them to the corresponding station data servers respectively.

[0027] In this embodiment, in the central data server, the global train basic line data can be split according to stations based on the pre-configured station information table, generating the station train basic line data corresponding to each station and distributing them to the corresponding stations.

[0028] Specifically, the central data server deploys the CTCS-0 level basic line data splitting software. The software needs to be configured with the station information table. Starting from the file address corresponding to the station information in the 2KADATA.BIN target file and ending at the file address of the next station information, it serves as the CTCS-0 level basic line data of this station and forms the 2KADATA.BIN target file of this station.

[0029] S13. The station data server sends the station train basic line data to the train running at the current station so that the train can perform operation control.

[0030] In this embodiment, when the train runs to the station, the station data server of the station sends the station train basic line data to the train, and the train performs operation control based on the station train basic line data. On the one hand, this solution can adjust and distribute the station train basic line data of each station in real time when the train basic line data is adjusted by different railway administrations, enabling the train to run according to the real-time train basic line data. On the other hand, the train in this solution receives the line data of the station in real time during operation, and the train does not need to store the global train line data. When the train changes the operation line, data replacement is not required either, improving the operation control efficiency of the train.

[0031] In this embodiment, when each railway administration compiles the train basic line data due to reasons such as train operation diagram adjustment or line construction and needs to be updated, it is generated by the data compilation client of each railway administration group company and then uploaded to the central data server. This can ensure that the global train basic line data in the central data server is real-time updated data.

[0032] In this embodiment, a monitoring program can also be set in the train basic line data memory of each data source. When the train basic line data in the memory changes, a data update condition is triggered, and the updated train basic line data of the data source is obtained and uploaded to the central data server. When the central data server receives the updated train basic line data, it updates the global train basic line data with the updated train basic line data, and then re-splits it to obtain the train basic line data of each station, and then distributes it to the station servers of the corresponding stations to ensure that the train operates according to the latest train basic line data of the stations.

[0033] In this embodiment, when the central data server receives the global train basic line data, it can compare whether the currently received global train line data is the same as the previously received global train line data. If they are the same, there is no need to update the global train basic line data. If they are different, it can update the train line data of all stations, or it can also update the train line data of the corresponding stations for the inconsistent line data.

[0034] In this embodiment, when the station data server receives the train basic line data of the station, it can compare whether the currently received train line data of the station is the same as the previously received train line data of the station. If they are the same, there is no need to update the train basic line data of the station. If they are different, it updates the train basic line data of the station.

[0035] Furthermore, when the central data server and the station data server determine that the line data needs to be updated, they can confirm with the data source to which the updated line data belongs whether the line data has changed, so as to verify the security of the data.

[0036] In this embodiment, to ensure sufficient data storage space in the train, after the train receives the train basic line data of the station, when it receives the train basic line data of the next station during the train's travel, it can delete the train basic line data of the previous station received. Specifically, after the train receives the train basic line data of the station, when the number of stations passed by the train reaches a preset number, it deletes the train basic line data of the station.

[0037] The present disclosure compiles the train basic line data of each data source to obtain the global train basic line data, splits the global train basic line data according to stations to obtain the station train basic line data corresponding to the stations, then sends the station train basic line data to the station data servers of the corresponding stations, and sends the station data servers to the trains for operation control, so that the trains no longer need to be manually reloaded with lines. At the same time, the trains only need to receive the station train basic line data of the stations they run to, greatly reducing the data storage pressure in the trains, and realizing the operation of the trains within the whole railway according to the station basic line data sent by the passing stations.

[0038] Please refer to Figure 2 , Figure 2 which is the second schematic flow diagram of a method for distributed deployment of train basic line data provided by the present invention. As Figure 2 shown, the method includes: S21. For any station, use the station information of the station in the global train basic line data as the starting information, and use the station information of each next station of the station as the ending information.

[0039] S22. Obtain the line data between the starting information and each ending information.

[0040] S23. Combine the starting information, the line data, and each ending information to generate the station train basic line data corresponding to the station.

[0041] In this embodiment, use the station information of the station as the starting information, and use the station information of the stations connected to this station as the ending information. The starting information and the ending information are the line ranges associated with this station. Then obtain the line data within the line range. The line data includes line information such as the station exit signal, speed limit information, curve information, crossing information, bridge information, gradient information, the next station entrance signal, and track information. Combine the starting information, each ending information, and the line data between the starting information and the ending information to generate the station train basic line data. The train can normally complete operation control within the line range of this station based on the station train basic line data.

[0042] Specifically, obtain the station exit signal, speed limit information, curve information, crossing information, bridge information, gradient information, the next station entrance signal, and track information between the starting information and each ending information to generate the line data.

[0043] S24. For each station, generate the corresponding station train basic line data respectively.

[0044] In this embodiment, as Figure 3As shown in the figure, the global LKJ basic line data is split into the station train basic line data of Station A and Station B according to the stations. The station train basic line data of Station A includes: Station A station information (station number 1), Station A outbound signal, speed limit information, curve information, crossing information, bridge information, gradient information, Station B inbound signal, track information, curve information, crossing information, bridge information, gradient information, Station B station information (station number 2), and Station B outbound signal; The station train basic line data of Station B includes: Station B station information (station number 2), Station B outbound signal, speed limit information, curve information, crossing information, bridge information, gradient information, Station C inbound signal, track information, curve information, crossing information, bridge information, gradient information, Station C station information (station number 3), and Station C outbound signal. In this way, the station train basic line data of other stations can be continuously split.

This connection architecture ensures the efficient transmission and real-time update of data. The ground base station not only receives information from the station data server but also is responsible for further broadcasting this information.

[0047] In this embodiment, after receiving this data, the ground base station can use wireless communication technologies (such as 4G / 5G, Wi-Fi, or dedicated wireless frequency bands) for broadcasting to ensure that trains within the coverage area can receive the latest train basic line data information in a timely and accurate manner. This broadcasting mechanism not only improves the information dissemination efficiency but also enhances the information interaction ability between the station and the train.

[0048] S32. After receiving the station train basic line data, the train conducts operation control based on the station train basic line data.

[0049] In this embodiment, the train can receive the station train basic line data by setting up a wireless receiving device. The wireless receiving device can include: on-vehicle antenna, wireless transmission device. Through the on-vehicle antenna, better communication with the ground base station can be achieved, and the train's train control equipment conducts operation control based on the station train basic line data.
