Automobile driving recording system

Abstract

The invention discloses an automobile driving recording system, which comprises a field programmable gate array (FPGA) image preprocessing unit and a digital signal processor (DSP) main processing unit connected with the FPGA image preprocessing unit and is characterized in that the FPGA image preprocessing unit is connected with a four-way video buffer and a video converter module, and the video converter module is connected with a four-way video input module. The DSP main processing unit is connected with a storage module and four-way alarm signals, and the FPGA image preprocessing unit sequentially transmits the processed four-way video signals to the DSP main processing unit for processing. The automobile driving recording system adopts the front-loading technology, feedbacks conditions of automobiles by utilizing active safety systems of the automobiles and controller area network (CAN) bus signals, and receives the signals timely, effectively and reliably for storage processing of data. The automobile driving recording system adopts a secondary storing mechanism, can store video information of a large amount in abnormal conditions under the condition that continuous 10 hours of original video is reserved and full reliability of the video is added, and greatly ensures completeness of the data.

Description

technical field [0001] The invention relates to a vehicle driving recording system, in particular to a video type vehicle driving recording system based on a surround-view camera, a CAN bus signal, a blind spot detection alarm signal and an FCW alarm signal. Background technique [0002] With the improvement of people's living standards, the number of cars used as a means of transportation continues to increase, and the possibility of traffic accidents and various unsafe incidents on traffic roads has also increased, causing huge losses to the country and the people. The stability of social order has brought adverse effects. In order to protect the safety and interests of drivers and pedestrians, the vehicle driving recording system with video continuous recording function can provide strong evidence for the cause and responsibility analysis of accidents. [0003] At present, most vehicles use rear-mounted driving recorders, and no driving recording system is installed befo...

AI Technical Summary

Problems solved by technology

The driving recorder used on the vehicle is divided into two categories: the first category is to record the status of the vehicle driving process in the form of text or code, the collected information is single, the readability is poor, and the legal basis is not sufficient; the second category is to use fragments Type video recording, mainly to record the situation around the vehicle after a traffic accident or other accidents on the traffic road, the video data collected is limited, it cannot guarantee to completely restore the situation when the accident occurred, valid data is lost, and evidence collection is insufficient

The rear-mounted driving recorder cannot collect the vehicle condition signal of the vehicle itself well, and cannot reflect the state of the vehicle well, and has defects in technical issues
