Train operation monitoring and recording device-based wireless data reloading method

Abstract

The present invention discloses a train operation monitoring and recording device-based wireless data reloading method, wherein the number of manually participated LKJ data reloading operations is reduced and the data exchanging efficiency is improved. Meanwhile, the working strength is lowered, and the conditions of wrong replacement, missed replacement and advanced replacement are avoided. According to the technical scheme of the invention, a vehicle-mounted data file is transmitted to the buffer of a vehicle-mounted data reloading module through a wireless network. The vehicle-mounted data reloading module simultaneously sends a preparation ready state to a ground system and a vehicle-mounted display to require the online update of vehicle-mounted data. The online update process is manually started on the vehicle-mounted display, or the online update process is started on the ground by the ground reloading control personnel. The wireless communication module acquires the identification number of a vehicle-mounted host plug-in arranged on the ground, and automatically compares the consistency of the identification number of the vehicle-mounted host plug-in of a vehicle-mounted terminal. Only the comparison result is consistent, the online update process can be continued till the online update process is completed.

Description

technical field [0001] The invention relates to the field of production management of train running monitoring records (LKJ) in the railway industry, in particular to a data wireless replacement management method based on train running monitoring records. Background technique [0002] LKJ data is the basis for the realization of LKJ control functions and the basis for operation analysis. In different operating routes and environments, LKJ data files change with changes in transportation equipment, facility technical data, or driving methods. The LKJ vehicle data file needs to be changed accordingly, and the vehicle control file version also needs to be upgraded accordingly. [0003] Usually, in the process of data replacement, the road bureau generally adopts manual boarding, timing, fixed point, and cable connection for manual replacement. The accuracy, timeliness, and security requirements of the existing data replacement methods are difficult to guarantee. In the face o...

AI Technical Summary

Problems solved by technology

[0004] 1. When locomotives and EMUs are in operation, the turnaround time is long, and data replacement is difficult;

[0005] 2. When constructing at multiple points on the same intersection, due to the different construction end times, the time limit requirements are high, and the data replacement organization is difficult;

[0006] 3. When the locomotive is entrusted to refit across bureaus, it is difficult to coordinate the entrusted work; there are many personnel involved in the unit and many links; and it is difficult to define work responsibilities;

[0007] 4. During emergency replacement, the timeliness of manual work is not high, and it is difficult to quickly complete data replacement

[0014] e) The existing "data processing method for remote loading of LKJ data", although the LKJ2000 device adopts a wireless method to realize LKJ data replacement, but its online update mechanism processing expression is vague, and data compression technology is not used for vehicle-to-ground transmission; LKJ The actual application scenario is not taken into account when the data is updated online after the on-board cache, and there is no replacement voucher code matching function when the vehicle is started and updated; the actual application scenario is not considered when the online update of the LKJ data is on-board cached, only the vehicle is updated without ground Start the update; did not consider the one-vehicle-one-number binding function, which is prone to wrong replacement; before the online update, due to special circumstances, a certain plan changed the locomotive to cancel the rollback function when reloading; did not consider the wireless automatic upgrade function of the vehicle wireless communication module, etc.

Therefore, it does not really meet the actual application on site, and cannot solve the problems existing in the current LKJ data replacement management site;
