Method for improving safety of driving test information and enabling synchronized reproduction of driving test information

Abstract

The invention relates to a method for improving the safety of driving test information and enabling synchronized reproduction of the driving test information. The method comprises a collection step in which multi-channel audio information and video information are converted into single-channel audio information HAS and single-channel video information CVS respectively; a storage step in which all information collected in the collection step together with testee information forms a driver test process multi-information audio-video DEMSAV file including different information in the driving test process; and a synchronized reproduction step in which a player which can replay the different information in a synchronized reproduction manner is used to reproduce all information recorded by the driver test process multi-information audio-video DEMSAV file in the synchronized manner. The method ensures that consulting results of different information which needs to be recorded in the test process are kept synchronized in time and position after test, a traditional file storage method is optimized, the safety of driving test information is improved, and the testee information can be inquired more conveniently and more rapidly.

Description

technical field [0001] The invention relates to a method for collecting and storing different types of information and its synchronous reproduction, in particular to a method for collecting and storing driving test information and its synchronous reproduction. Background technique [0002] After the relevant provisions of the Ministry of Public Security on the process of obtaining and testing motor vehicle driving licenses were changed from the previous Order No. 111 to Order No. 123, the evaluation method of the driving skills test process of motor vehicle candidates has been changed from manual to computer-based, and requires the entire All the information of the examination process can be traced at any time, that is to say, the examination process of any candidate can be completely played back or restored at any time, so that it can be re-examined or corrected correctly. [0003] In order to achieve the above purpose, recording all the information of a candidate in the ex...

AI Technical Summary

Problems solved by technology

[0018] 3.1. When tracing the source of the examination process, it is necessary to use a variety of system methods that do not have a one-to-one correspondence in time. Therefore, neither theory nor practice can solve the problem of audio and video information during playback. The synchronization problem of vehicle position information, operation information and other information, especially when playing back video and driving trajectory, is particularly prominent. The driving trajectory that can only be drawn asynchronously and the video signal recorded in real time by the test vehicle The time difference is unstable and cannot be controlled at all, which can easily cause visual errors. When there is a point of deduction for judgment, it will make the observer think it is a judgment error, and even cause doubts or disputes about the correctness;

[0019] 3.2. Use the current database technology to analyze static information such as test vehicles, examinees, examiners, test time, test results, judgment basis, real-time time and location of test vehicles When dynamic information is stored, due to the universality of the interface and the openness of the technology, its security cannot be guaranteed, and it will be easily tampered by criminals, thus destroying the impartiality and fairness of the examination process and information data. authenticity;

[0020] 3.3. Since the examination information of the same candidate is stored in multiple files of different types, it is very troublesome to search, which is labor-intensive and time-consuming. It is even more difficult to reproduce synchronously, and it is often only possible to achieve a time difference of no more than 10 minutes
