Device for recording and storing accidents for automobile

Abstract

The invention discloses a vehicle accident record storing device. The device is characterized in that at least two groups of memories are arranged, or a memory which is divided into at least two memory areas is arranged, wherein, the first memory group or the first memory area is used for recording the realtime form, namely the continuous and uninterrupted digital video / audio data; while the second memory group or the second memory area is used for skimming from the first memory device group, and recording and storing the digital video / audio data of the alarm when each accident occurs and / or the pre-alarm or the post-alarm, wherein, the duration of the pre-alarm and the post-alarm can be automatically set or adjusted, for example, the duration can be set to be 10 seconds before or after the alarm when the accident occurs, therefore the vehicle accident record storing device can carry out the long-time safety monitoring operation, and can completely record and store the digital video / audio data of the alarm when each accident occurs as well as the pre-alarm and the post-alarm during the safety monitoring period, so as to prepare for the long-time storage and the ready reference, and increasing the use efficiency of the vehicle accident record storing device.

Description

technical field [0001] The present invention relates to a vehicle accident recording and storage device, especially a device with at least two sets of memory or memory areas, and wherein the first set of memory or memory areas is used to record real-time audio-visual data, and the second The group memory or memory area is used to retrieve and record the complete digital video and audio at the time of each accident and / or its pre-alarm or post-alarm duration from the first group memory or memory area data. Background technique [0002] Automobiles are quite popular means of transportation, and various types of equipment can be installed in automobiles according to the different needs of users, such as global positioning systems (GPS, global positioning system), or vehicle safety monitoring systems, etc. It is widely used by car owners or drivers; and the car safety monitoring system generally uses an audio-visual recording device such as a commonly used car digital video rec...

Problems solved by technology

[0004] However, due to the limitation of the interior space of the car, a digital video recorder (DVR) for a car generally chooses to use or install a set of memory (storage media) to record real time (real time), that is, continuous and uninterrupted digital audio and video. data; and because the recording capacity of the group internal memory is often limited, if the group memory device adopts the mode of recording real-time audio-visual data, it can only reach the recording capacity of a certain period of time, such as only one day or several days can only be recorded. One day’s real-time audio-visual data, according to the use function of the general car digital audio-visual recorder (DVR), after exceeding the corresponding period of the allowable capacity, the group memory will directly produce rewriting (re -write) function, that is, when the real-time audio-visual data recorded and stored exceeds the allowable capacity of the group memory device, the group memory will automatically start from the beginning (the starting point of the memory) and continue recording to make a new record The real-time audio-visual data replaces (overwrites) the front section old audio-visual data recorded before, and if the said front section old audio-visual data is not backed up in time, it will be completely lost and cannot be stored; if an accident is recorded in the said front section old video data The audio-visual data at the time of occurrence may be replaced (overwritten) by new audio-visual data due to lack of timely backup and storage, which will relatively reduce the use efficiency of the vehicle digital video recorder and the effect of the vehicle safety monitoring system

[0005] Although the problems referred to above can be solved by expanding the capacity of the single group of memory to extend its recording time, the existing space of the digital video recorder (DVR) for vehicles is limited, so that expanding the capacity or installing another high-capacity memory is subject to Restrictions are not easy to achieve, and relatively will increase the cost of the above-mentioned digital video recorder (DVR) for vehicles; and if the single group memory recording method is changed from recording real time (real time), that is, continuous and uninterrupted digital video Data, instead of recording non-real-time digital audio-visual data, such as intermittent recording, but it will relatively affect the monitoring quality and efficiency of the car digital video recorder (DVR) or car safety monitoring system
