Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] During the traditional train operation, the CBTC signal transmits data through WLAN. Due to the small bandwidth of WLAN, it cannot provide free bandwidth for log transmission. Therefore, the logs generated by each on-board device are stored locally on the device. When you need to query the log, you need to from The logs are downloaded ...

Abstract

The embodiment of the invention discloses an LTE-based vehicle-mounted log automatic uploading method and system. An LTE wireless communication mode is adopted as a communication mode of CBTC signal transmission, and the LTE wireless communication mode can support a larger communication bandwidth, so that when the CBTC signal is transmitted, an unoccupied bandwidth can exist for transmitting log data. The second priority of the data transmission of the CBTC signal is higher than the first priority of the log data transmission, so that the log data is only transmitted when the network is idle,the transmission of the CBTC signal is not influenced, and the normal operation of a train is ensured. And each vehicle-mounted device uploads the log data to a log server, and the log server stores the log data of each vehicle-mounted device. And when the log data needs to be searched, the required log data can be searched only through the log server, so that the operation is convenient, the timeis saved, and the working efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of driving data processing, in particular to a method and system for automatically uploading an LTE-based vehicle log. Background technique [0002] In the rail transit signaling system, on-board signaling equipment, as an important safety-related equipment, needs to record a large amount of log information in real time for subsequent abnormal analysis, accident analysis, and daily analysis to discover potential problems. The daily log data recorded by the signal vehicle equipment is usually on the order of 1000MB, but the existing wireless communication system often only allocates a small bandwidth but highly reliable communication channel for the signal equipment. This channel is designed to transmit a small amount of control signals reliably and cannot be used for Transfer large amounts of log data. [0003] In the existing rail transit projects, the log data of the latest period is...
