Description
Technical field
The present invention relates to one lead based on LKJ and audio-visual synchronization intelligent retrieval analytical technology thereof
Territory, particularly relates to one and analyzes method based on LKJ and audio-visual synchronization intelligent retrieval thereof.
Background technology
Along with coming into operation of new harmonious type, the 6A system that locomotive is equipped with can realize machine
Car situation and the complete monitoring of crew's cargo handling operation, by utilizing the data retrieval of 6A system
Analyze and become the important means of engineering system operation management, but there is also that file is many, recall precision
The problem such as low, as a example by HXD2 type locomotive, each documentation time 6 is hour, every machine
Car list plows generation data file 4, and the locomotive 6A file that safe and comfortable locomotive depot monthly produces is about
19200, every operation management personnel check that 1 file needs 5 minutes, be by all numbers
According to document retrieval one time, 40 operation management personnel are needed to work every day 10 hours, with 20
It time just can complete, in the face of the data file of such magnanimity has manually been analyzed, and Shi Bizao
Become inefficiency.
On the other hand, locomotive depot attaches troops to a unit LKJ depth analysis system, can only be to locomotive fortune note LKJ
File carries out retrieval analysis, LKJ is analyzed the many problems found and cannot search former intuitively
Cause, although locomotive is attached troops to a unit after 6A system, it is possible to the data file transferring this locomotive is looked into
See, but need manual the searching in the data file of magnanimity of operation management personnel, often one
Minor issue, needs to expend and goes for a long time to search, have access to data file, often result in analysis management
Delayed.
Summary of the invention
