Wireless vehicle-mounted USB flash drive video recording control device with hard disk backup function

Abstract

The invention discloses a wireless vehicle-mounted USB flash drive video recording control device with a hard disk backup function, wherein a central processing unit detects the information of a USB storage control module or a CAN bus control module and starts to record videos; a multipath video switching module selects a channel which needs to record the videos; an audio / video coding module codes audios / videos; the central processing unit writes information into a video recording file; a real-time clock module sends date and time parameters of a system to the central processing unit and displays date and time on the video recording file; the USB storage control module stores the video recording file in an external storage medium in real time; and a hard disk backup module can backup data inside the USB storage medium in a hard disk and can also read and write digital data inside the hard disk through a network module. The invention has a CAN bus control function, a U flash drive storage function, a hard disk backup function and a network transmission function and can collect various data through real-time monitoring, thereby being convention to timely master occurred information and events.

Description

technical field [0001] The invention relates to an embedded vehicle-mounted video recording control device, in particular to a wireless vehicle-mounted U disk video recording control device with a hard disk backup function. Background technique [0002] Vehicle-mounted video recording system is widely used in production management, security and other occasions because of its intuition, convenience, and detailed information content. and other mobile vehicles. Due to the physical characteristics of the hard disk, the traditional vehicle-mounted hard disk video recorder cannot be adapted to mobile vehicles with severe bumps. Due to the high power consumption of the hard disk and unstable power supply on mobile vehicles, traditional vehicle-mounted hard disk video recorders are often difficult to adapt. Due to the harsh environment of equipment used in mobile vehicles, traditional on-board hard disk video recording or on-board SD card video recording often has abnormalities and...

Problems solved by technology

Due to the physical characteristics of the hard disk, the traditional vehicle-mounted hard disk video recorder cannot be adapted to the mobile vehicle with severe bumps. Due to the high power consumption of the hard disk and the unstable power supply on the mobile vehicle, the traditional vehicle-mounted hard disk video recorder is often difficult to adapt

Due to the harsh environment of the equipment on the mobile vehicle, the traditional car hard disk video or car SD card video often has abnormalities and stops working, and there are also problems such as incomplete video files and video files that cannot be played.

The connection between the traditional car hard disk video recorder and the computer needs to add a conversion device, and the connection between the SD card video recorder and the computer needs to add a card reader. There may be compatibility problems, and it is very inconvenient to use in practice.
