A data wireless replacement method based on a train operation monitoring and recording device

Abstract

The invention discloses a data wireless replacement method based on a train operation monitoring and recording device, which reduces manual participation in LKJ data replacement, improves data replacement efficiency, reduces work intensity, and prevents wrong replacement, missed replacement, and early replacement. The technical solution is as follows: the on-board data file is transmitted to the cache of the on-board data replacement module through the wireless network; the on-board data replacement module simultaneously sends the ready status to the ground system and the on-board display to request online update of the on-board data; manually starts on the on-board display The online update process or the ground change control personnel use the ground to start the online update; the wireless communication module obtains the identification number of the vehicle-mounted host plug-in configured on the ground, and automatically compares it with the number of the vehicle-mounted host plug-in. Only when the comparison is consistent can the process continue Online update process until the update is complete.

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;
