Vehicle travel security data recording system based on video capture and processing technology

Abstract

The invention discloses a vehicle travel security data recording system based on a video capture and processing technology, which comprises a video signal acquisition module, a video signal automatic cleaning module, a control board data acquisition module and a data storage and processing module, wherein the video signal acquisition module is in charge of video signal acquisition and signal transmission; the video signal automatic cleaning module is used for detecting redundant video signals and cleaning data containing noise and can report to other modules; the control board data acquisition module is in charge of acquiring working condition parameters of a vehicle in real time and uploading parameter data to a bus; and the data storage and processing module is used for coordinating works of other modules, providing data interfaces, storing relevant data, carrying out certain analysis and processing on the data and analyzing reasons and promoting when the system has abnormal conditions. In the modules, the video signal acquisition module is accessed into a CAN bus by being connected with the signal automatic cleaning module, and the control board data acquisition module and the data storage and processing module are directly accessed into the CAN bus so as to form an embedded system.

Description

Technical field: [0001] The invention relates to the fields of automobile safety and information data recording, in particular to an embedded system for recording video information and safety information during the driving of a motor vehicle. Background technique: [0002] With the rapid increase in the number of motor vehicles, related safety accidents are showing a rapid growth trend. These accidents have also brought huge losses to the state and people's property. According to the new road traffic safety law, the parties need to collect evidence after the accident , but in most cases, the evidence collection work is quite difficult, so a system that can record comprehensive safety information of motor vehicles can be invented, which can restrain bad habits of drivers, curb fatigue driving, speeding and other illegal behaviors, and Ensuring the traffic safety of motor vehicles is also of great significance for the analysis and identification of road safety accidents.

Problems solved by technology

[0002] With the rapid increase in the number of motor vehicles, related safety accidents are showing a rapid growth trend. These accidents have also brought huge losses to the state and people's property. According to the new road traffic safety law, the parties need to collect evidence after the accident , but in most cases, the evidence collection work is quite difficult, so a system that can record comprehensive safety information of motor vehicles can be invented, which can restrain bad habits of drivers, curb fatigue driving, speeding and other illegal behaviors, and Ensuring the traffic safety of motor vehicles is also of great significance for the analysis and identification of road safety accidents

[0003] At present, the driving information recording instruments on the market are generally designed according to the national recorder specifications in the 1980s and 1990s, which have fallen behind the design standards of modern electronic equipment, and most of the data recorded are part of the vehicle driving data, plus the cost of use and equipment. Due to problems such as size, only some large long-distance buses are equipped with driving information recorders when they leave the factory, and the recorded data standards are different, which cannot be used as strong evidence for analyzing accident rights and responsibilities. In addition, some recording instruments are not designed. Considering the user's privacy rights and interests, some information that may violate the user's privacy right is recorded, making it difficult to promote the product
