[0002] At present, the LKJ train operation monitoring and recording device has played a significant role in ensuring railway transportation safety and promoting locomotive safety management. However, when updating temporary data, it is necessary to manually get on the train to update the device. Each data maintenance will cause a lot of waste of manpower and material resources.

[0003] Under special circumstances, when the locomotive has been out of the warehouse when the temporary dispatch order is issued, the LKJ temporary data file cannot be updated through the manual IC card. The driver is notified by the ground through the radio, and the driver manually controls the speed. The method of analyzing whether the section is speeding through retirement analysis poses a great safety risk. Even on GSM-R covered lines, the CTC system can receive the train number information through the GSM-R / GPRS network and transmit the dispatch order information to the on-board locomotive integrated wireless communication equipment through the wireless network. However, since the dispatch order received by the locomotive integrated wireless communication equipment is text content and cannot be connected to LKJ, it can only be signed by the driver and the speed can be controlled manually, and the LKJ machine-controlled speed limit cannot be achieved.

[0004] Therefore, it is necessary to provide a LKJ temporary data updating method to solve the problem that the LKJ temporary data cannot be updated in real time in the prior art, avoid human-controlled speed limit, realize full-process machine-controlled speed limit, and ensure driving safety.

[0032] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve corresponding technical effects can be fully understood and implemented accordingly. The embodiments of the present invention and the various features in the embodiments can be combined with each other without conflict, and the technical solutions formed are all within the protection scope of the present invention.

[0033] Embodiment 1

[0034] The present invention uses the following terms:

[0035] LKJ: Train operation monitoring device.

[0036] LMD: Train operation monitoring and management system.

[0037] LKJ basic data: refers to the basic line data of equipment and facilities such as lines, signals, contact networks, stations, etc. included in the "Technical Data on Train Operation Diagrams" of the Railway Bureau, as well as basic operation organization data such as the tracks through which stations receive and dispatch trains, special locations at the starting distance, and the sections in charge of locomotives (EMUs).

[0038] LKJ temporary data: refers to various temporary data compiled into LKJ temporary data files and loaded into LKJ equipment based on the operation disclosure and dispatching orders issued in advance to the relevant locomotive depot, which implements deceleration control on train operation or changes the driving mode and prompts related operations.

[0039] like Figure 1 As shown, an embodiment of the present invention provides a LKJ temporary data updating method, comprising the following steps S101 to S103:

[0040] Step S101: Upload target LKJ temporary data to the target vehicle-mounted subsystem.

[0041] For example, the ground subsystem uploads the LKJ on-board temporary data to the on-board subsystem for caching through the wireless communication network in accordance with the LKJ temporary data update instruction, and checks the integrity and accuracy of the data transmission.

[0042] Step S102: after receiving the target update instruction, control the target vehicle-mounted subsystem to update the target LKJ temporary data to the target LKJ device and obtain the target update status.

[0043] For example, after receiving the data update instruction, the vehicle-mounted subsystem updates the cached data to the LKJ device.

[0044] Step S103: Control the target vehicle-mounted subsystem to send the target update status to the ground subsystem.

[0045] For example, the data update result is sent back to the ground subsystem, and the ground subsystem monitors the LKJ vehicle-mounted temporary data update result in real time.

[0046] The vehicle-mounted subsystem is composed of the LKJ vehicle-mounted safety communication plug, which has mobile communication functions and vehicle-mounted network boundary isolation, network control, data encryption and other security protection functions, and realizes the reception, decompression, verification, caching and update of LKJ temporary data;

[0047] The wireless communication network consists of a public mobile communication network and a private network. A dedicated IPSec VPN encryption channel is established between the vehicle and the ground to achieve two-way data encryption transmission between the system and the ground. The ground subsystem consists of a network access layer, an application layer, and a terminal workstation. The vehicle-mounted subsystem communicates with the ground subsystem through the access layer to achieve vehicle-to-ground transmission, secure access control, and mandatory identity authentication of LKJ temporary data files; the ground subsystem provides users with LKJ temporary data update management services and data monitoring functions through application terminals and mobile terminals.

[0048] The purpose of the present invention is to solve the problem of updating the temporary data of locomotive LKJ and realize online real-time loading of temporary data of LKJ, especially in some extreme cases, when the temporary dispatching order is issued, the locomotive has been out of the warehouse and the temporary data of LKJ cannot be loaded. The system can be used to load the temporary data of LKJ and realize the speed limit of locomotive control.

[0049] The present invention applies mature FLASH storage technology, Wifi / 3G / 4G wireless transmission technology, CAN communication technology, and encryption technology to ensure stable and reliable operation of the system. Ensure the full management and monitoring of LKJ temporary data, realize remote transmission of LKJ temporary data, and implement mastery and monitoring of update progress through authority control, security mechanism guarantee, transaction record and other means to ensure the card control of LKJ temporary data update operation. The correctness of the transmitted LKJ temporary data file is guaranteed by locomotive unique identification, file full text verification means, asymmetric RSA encryption and decryption technology, and CRC48 verification. Eliminate the problem of not being able to update LKJ temporary data in time due to locomotive position, reduce the difficulty of LKJ temporary data update operation, and save manpower and material costs. Realize remote real-time loading of LKJ temporary data, solve the problem that when temporary data is released, the locomotive cannot update temporary data in time when leaving the warehouse. The LKJ temporary data update operation is changed from human control to machine control, reducing the risk of human error and omission.

After the director of the dispatch room reviews and approves it, it is sent to the operation management duty officer in the maintenance dispatch room.

[0053] 2) The transport officer on duty uploads the temporary data file of the LKJ to be boarded into the system.

[0054] 3) The system reads the locomotive operation plan information (planned train number, operation route) from the transportation safety system and the real-time locomotive status information (actual train number, next station, kilometer mark) from the LMD system to assist the transportation management officer in selecting locomotives to be updated.

[0055] 4) The operation management officer selects a specific locomotive to upload the LKJ temporary data file based on auxiliary information such as locomotive and train number, and uploads it to the LKJ on-board terminal through this system.

[0056] 5) The locomotive crew confirms the uploaded temporary data content through the LKJ on-board display, records the confirmation information, and feeds it back to the operation management officer on duty through the system.

[0057] 6) The operation management officer on duty confirms the temporary data file upload confirmation result (system upload result, crew confirmation result) and completes the LKJ temporary data file update operation.
