Problems solved by technology

[0004] 1. Since all IDE hard disks should be placed in the DVR host, when any IDE hard disk fails, it must be shut down, powered off, and opened for repair. During this period, the video information of the monitored area cannot be saved, which often may lead to certain dangers
[0005] 2. Sequential storage is used in the storage method, that is, when one hard disk is full, then the second hard disk is stored. Once one of the hard disks is damaged, it is difficult to recover the lost data, so the security is poor
[0006] 3. IDE hard drives are usually connected by cables. Each IDE interface can only be connected to two IDE devices at most. When fully configured, due to the high density of hard drives inside the chassis, there are many data cables and power cables, and the video storage is usually 24 hours. Write in real time, causing the hard disk to generate a lot of heat, which will greatly shorten the service life of the hard disk
This IP-SAN method has high reliability and is easy to manage, but the networking is complicated and the cost is high, so it is not suitable for small-scale monitoring systems

Embodiment 1

[0028] Such as figure 1 Shown is a schematic structural diagram of the first embodiment of the video information storage device of the present invention. In this embodiment, the video information storage device includes an analog-to-digital conversion module 1, a video encoding module 2, a storage control module 3 and a hard disk 4 in serial transmission mode. For some monitoring cameras, they will send captured video analog signals to the analog-to-digital conversion module 1, and the analog-to-digital conversion module 1 can perform analog-to-digital conversion on the received video analog signals and output digital signals. The video coding module 2 is connected to the analog-to-digital conversion module 1, receives the digital signal output by the analog-to-digital conversion module 1, and then performs video coding on the digital signal, and packs it into a video data stream.

[0029] The storage control module 3 receives the video data stream output by the video encodin...

Embodiment 2

[0033] Such as figure 2 Shown is a schematic structural diagram of the second embodiment of the video information storage device of the present invention. Compared with the previous embodiment, the present embodiment adopts a serial ATA (Serial Advanced Technology Attachment, referred to as SATA) hard disk 41, and the storage control module 3 is correspondingly a SATA control module 31, which can provide the interface of the SATA hard disk 41, and the video data stream Store to the SATA hard disk with a predetermined storage policy.

[0034] SATA is a serial transmission mode, and the data transmission rate of SATA II has reached 300MB / s, which is much higher than the maximum transmission rate (133MB / s) of the parallel transmission mode. The SATA hard disk supports hot swap, and there is no need to cut off the power when replacing it.

Embodiment 3

[0036] Such as image 3 Shown is a schematic structural diagram of the third embodiment of the video information storage device of the present invention. Compared with the first embodiment, the storage control module of this embodiment is a serial attached small computer system interface (Serial Attached Small Computer System Interface, referred to as SAS) control module 32, because SAS is an upgrade of SATA, it is also a serial transmission Mode, but also has the ease of management and reliability of Small Computer System Interface (SCSI for short), so it has better performance and higher speed. It can be connected to SATA hard disk 41 or SAS hard disk 42 .

Abstract

The invention comprises: a D / A converter, a video encoder, a storage controller, and a SATA hard drive. The method comprises: making A / D conversion for the received analog signals in order to output digital signals; making video encode for the digital signals, and packaging the encoded digital signals as video bit-stream; saving the video bit-stream by using a preset strategy.

Description

technical field [0001] The invention relates to the field of information storage, in particular to a device and method for storing video information. Background technique [0002] In some occasions where monitoring equipment needs to be set up, real-time monitoring and recording and storage of video are very necessary. For general monitoring equipment, the functions of monitoring and recording can be realized. Through real-time monitoring, dangerous, illegal, and criminal incidents can be discovered or prevented in a timely manner, and the recorded video data has also become an important basis for evidence collection when handling cases by public security and justice, and can also greatly reduce the incidence of crimes in monitored areas. With the emergence of various high-performance monitoring equipment, the amount of data has also increased sharply, which puts forward the requirements of large capacity and high reliability for the storage of monitoring video information. ...
