Distributed node video monitoring system and management method thereof

Abstract

The invention relates to a distributed node video monitoring system, which comprises a plurality of VSS service nodes and a service center management platform for managing the plurality of the VSS service nodes, wherein each VSS service node is also connected with a device front end PU for acquiring video monitoring information and a client CU for showing the video monitoring information; the client CU and the device front end PU directly access each VSS service node through the service center management platform to acquire data; and the plurality of the VSS service nodes are kept synchronous with the data in the service center management platform. The invention discloses a novel distributed node structure and two synchronization mechanisms based on the structure adopted by the prior video monitoring system, and the distributed node video monitoring system is perfected by ensuring the data consistency of each node so that certain defects of the prior video monitoring system can be overcome well.

Description

technical field [0001] The invention relates to a distributed node video monitoring system and a management method thereof. Background technique [0002] Network video monitoring service is a value-added service based on broadband network remote image monitoring, transmission, storage and management. This business utilizes broadband network to connect scattered and independent image acquisition points to the Internet, so as to realize unified monitoring, unified storage, unified management and resource sharing across regions and in the whole range. The network video surveillance system meets the needs of public surveillance and professional surveillance at the same time. With independent networking, it can not only carry out video surveillance services on mobile streaming media, but also carry out video surveillance services on interactive Internet TV (IPTV) networks. [0003] Existing video surveillance systems are generally composed of multiple subsystems. If the cooperat...

AI Technical Summary

Problems solved by technology

[0006] 1. The RGM Manager module concentrates too much business processing, which can easily become the performance bottleneck of the system

[0007] 2. The data interaction between the database server and each subsystem is too frequent. When the amount of data is large, it is easy to form a bottleneck of the database

[0008] 3. Does not support large-capacity devices

According to the existing structure of the commercial video surveillance system, when large-capacity front-end equipment access, media forwarding, customer access, and video storage are required, the business will be processed in the registration management (RGM Manager) module of the system, which causes a lot of damage to the system. High pressure often causes response delays and system crashes

[0009] 4. The scalability of the system is not good

[0010] 5. Poor scalability of the platform

When this happens, it usually leads to data conflicts when a new device is connected; because the status information of the front-end device is inconsistent with the database data, the monitoring cannot be performed normally; the device permissions saved by each node conflict, so that the user accesses different nodes. The obtained device permission information is displayed differently

When these situations occur, the existing system can only restart the node device to re-acquire data to maintain consistency, and frequent device restarts will cause business interruption, which is unacceptable to users
