A method for downloading and storing on-board video data in a locomotive

Abstract

The invention discloses a locomotive on-board video data downloading and storing method comprising the following steps: (1) pre-specifying a downloading and storing mode and information of data needing downloading and storing, and storing the downloading and storing mode and the information of data needing downloading and storing in equipment to be used for storage; and (2) when there is a need to acquire on-board video data of a locomotive, accessing the equipment to be used for storage and acquiring the corresponding downloading and storing mode and the information of data needing downloading and storing, finding out target video data from the on-board video data of the locomotive under control according to the acquired information, and downloading the target video data and storing the target video data in the equipment to be used for storage. The locomotive on-board video data downloading and storing method of the invention is advantageous in that implementation and operation are simple, the cost is low, the downloading and storing mode is flexible, locomotive on-board video data can be downloaded and stored automatically, and video data is not easy to loss.

Description

technical field [0001] The invention relates to the technical field of locomotive video monitoring, in particular to a method for downloading and storing video data on a locomotive. Background technique [0002] The locomotive on-board video monitoring system is an important system of the locomotive safety system. It monitors and records the power room, machinery room, driver's cab, and road conditions ahead through multiple cameras installed in the front, rear, and interior of the locomotive in real time. The running status of the locomotive enables the driver to know the situation inside and outside the locomotive in time, and at the same time, image records the running status of the locomotive. [0003] After the locomotive on-board video monitoring system collects video image information, fire alarm information and other locomotive information in real time, video data is obtained after comprehensive processing such as image compression coding and subtitle superposition. ...

AI Technical Summary

Problems solved by technology

When it is necessary to check the video data of a certain period of time, it is necessary to wait until the locomotive returns to the locomotive depot, and the technician disassembles and replaces the storage hard disk, and then connects a special device for screening and dumping to extract the required video data and locomotive data. For analysis and processing, the operation process is cumbersome, the required operation workload is large, and the time span is long. If the locomotive runs online for a long time, the data cannot be fed back in time; at the same time, the frequent disassembly of the storage hard disk for data extraction will easily cause loosening of the interface, which is not conducive to equipment maintenance

In addition, if the storage hard disk is lost due to careless storage, it will directly lead to the loss of video data

Even if the local storage disk uses a mobile disk to store video data to facilitate replacement at any time, manual operations are still required to download and store the required video data, which is inconvenient to use and operate. When a hard disk failure occurs during locomotive operation, there is no backup The replacement of the hard disk will also cause the loss of this segment of data
