Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Such as figure 1 As shown, in order to ensure the high-performance operation of the entire system, the system deploys multiple servers, which can form multiple paths from the video camera to the client. Based on this, load balancing research is carried out on data transmission. Load balancing is a technique used in the network to divide the load among multiple network links or servers.

[0024] First of all, the original two-level subscription model needs to be modified to a three-level subscription model, that is, after the server receives the subscription from the client, it does not log...

Abstract

The invention discloses a video monitoring method and a video monitoring system under a large-scale data concurrency environment. The system comprises a video collection unit comprising an industrial control machine and at least one camera, wherein the camera is used for shooting a video, and the industrial control machine is used for collecting video data and forwarding the data to a server; a monitoring center comprising the server, a load measurer, a load balancer and a scheduling dispenser connected in sequence; and a client used for sending requests and subscribed messages to the server, and receiving video data. According to the method and the system provided by the invention, the industrial control machine participates into forwarding, so that the load of the server is further relieved. Servers mutually serve as backups for one another, so that occurrence of a single point failure is reduced, and higher reliability is provided.

Description

technical field [0001] The invention relates to the technical field of video data processing, in particular to a video monitoring method and system in a large-scale data concurrent environment. Background technique [0002] Over the past 20 years, the video surveillance system has experienced from the first generation 100% analog system (VCR), to the second generation partly digital system (DVR / NVR), and then to the third generation fully digital system (network camera and video Server) three stages of development and evolution. In this process, although the functions and performance of the video surveillance system and equipment have been greatly improved, they are still limited by some inherent factors, including the physiological weakness of human beings as monitors, and the The configuration of the video surveillance system and the limitation of the function and performance of the video surveillance equipment. These limiting factors make all kinds of video surveillance...
