technical field

The present invention relates to remote video data collection and management, in particular to a cloud storage-based video data collection and management system and method.

Background technique

At present, there are two types of remote video monitoring systems. One is that there is no on-site monitoring system at the monitoring site, but the data is collected and sent directly to a remote computer for processing. This remote monitoring is not much different from general on-site monitoring, only the data The transmission distance is farther than the on-site monitoring system, and other parts are the same as the on-site monitoring system; the other is the coexistence of on-site monitoring and remote monitoring. Generally, fieldbus technology is used to connect the monitoring equipment distributed in various areas, so that the stage of discrete units enters the stage of integrated units, and then the services of each management site are connected by LAN, thus forming an intranet (Intranet) ). Due to the establishment of a basic network information infrastructure, equipment monitoring and maintenance technology has entered the stage of an integrated system, and resource and information sharing has basically been realized within a unit.

However, as the current monitoring area is getting wider and the data flow is increasing, the original video data collection method and monitoring system cannot meet the current needs. There is an urgent need for faster data collection methods and more flexible and easy-to-use video data management methods that are not restricted by regions.

Detailed ways

The system of the present invention will be described in detail below with reference to the accompanying drawings.

Figure 1 is a schematic structural diagram of a video data collection and management system based on cloud storage, including a video data collection module, which uses multi-channel collection, analysis and splicing to quickly collect video data; a video compression module, which is used to combine the collection The data or the existing uncompressed video image coding compression and temporary storage; cloud data storage module, used to store video data; data transmission module, upload data to cloud storage or retrieve from cloud storage and download to the terminal through wired or wireless mode equipment.

The video data collection module contains at least 2 collection points. The collection point starts to collect video data after the moving target enters the collection area. These segmented video data are then transmitted to the video analysis module to clarify the position and time relationship between the segmented videos. After determining the connection sequence and overlapping parts, it is handed over to the video splicing module for splicing, so that the movement of moving objects in the entire collection area can be quickly collected.

Spliced video data or existing but uncompressed video data such as DVD, video and other video data are sent to the video compression module, which is generally a small computer host or simple integrated electronic equipment. The CPU processor in the module transmits the received data to the video encoder for encoding and compression. The encoding method adopts standard definition SD such as MPEG3 or MPEG4 or high-definition HD such as H.264 for compression, and then stores the compressed video into the temporary storage hard disk to complete the video data compression.

The data in the temporary storage hard disk is uploaded to the cloud data storage through the data transmission module by means of wired such as broadband network or wireless such as WIFI and 3G.

After that, if the administrator needs to call the video recording of a certain period of time, he can log on to the visual management interface through any terminal connected to the network, such as a computer or a mobile phone, retrieve the required video through the video data retrieval device, and download it to the terminal Watch it on your device.
