With the rapid economic and social development, large and medium-sized enterprise groups and government units are faced with unprecedented operational pressures and market competition, and higher requirements are placed on the operation and development of enterprises. Many users are increasingly interested in establishing a large-scale networked video surveillance system that covers all business premises and present a strong application demand.
The surveillance systems of large and medium-sized enterprise groups and government units generally cover the group's headquarters, provincial branches, and municipal branches and cities in each province. The monitoring sites are widely distributed and the organizational structure is hierarchical. Therefore, the corresponding monitoring system should also have a hierarchy corresponding to the management organization structure. This level of performance can be expressed as: the superior can access the monitoring content of the lower level, the lower level cannot access the higher level monitoring content, and the peers cannot exchange visits to each other's monitoring content. Because of its clear hierarchy, the tree-structured monitoring system is undoubtedly best suited for the monitoring needs of this group unit.
First, the status of tree structure monitoring system
The existing tree-like monitoring system relies on a composite area video monitoring system with a flat structure, that is, a multi-level tree-like monitoring system is formed by superimposing a directory with authority information on a flat composite area video monitoring system. The flat composite video surveillance system can realize full interconnection of information and sharing of messages between systems. Therefore, when the routing table is synchronized, if the sub-domain routing information changes, it needs to be synchronized from the sub-domain to the central domain and then from the central domain to the sub-domains. The tree synchronization structure is a composite of multiple star synchronization structures. When this kind of tree monitoring system synchronizes routing information, it needs to be upward and then synchronized downwards. For a monitoring system in which the privilege has a hierarchical relationship and a horizontally unrelated tree structure, the two-way synchronization of the routing information becomes redundant. Moreover, in the existing tree-like monitoring system, the node's record directory is unique in the entire tree-like system, and the numbering scheme of area coding and hierarchical sorting is adopted, making the tree-like monitoring system not easy to expand.
Second, Warburg launches a hierarchical tree structure monitoring system
Huaping's tree-like hierarchical structure monitoring system includes multi-level server, multi-level monitoring client and multi-level monitoring equipment.
The multi-level server includes a plurality of servers hierarchically layered to return a monitoring resource list to the verified monitoring client. The levels of the servers at different layers are different, and the levels of the servers at the same layer are the same. The multi-level monitoring client includes a plurality of monitoring clients respectively connected to the servers at various levels to submit account verification to the corresponding server. The monitoring client selects and broadcasts or receives monitoring streaming media according to the monitoring resource list. The multi-level monitoring device includes a plurality of monitoring devices respectively connected to the servers at various levels.
Monitoring client server, each level of server includes database, background management module and monitoring service module; database is used to store monitoring related information, monitor related information including monitoring data, monitor client data, monitor status and monitoring log; The management module is connected to the database in the same server to manage the creation of monitoring information; the monitoring service module is connected to the database in the same server to process the monitoring data in the database and transfer the monitoring data to Each server connected to the server at the level is then transmitted to the monitoring client connected to each server.
Each lower-level server submits the node information in the respective tree-level hierarchical monitoring system to the corresponding upper-level server for verification according to the monitoring hierarchy requirements, and establishes a connection with the corresponding upper-level server after the verification passes. . Each server and each monitoring client are connected using the TCP/IP protocol. When a monitoring device in a tree-like hierarchical structure monitoring system goes online, it issues the login information to the upper level through the nodes in the monitoring system; each node compares with the synchronized channel ID in the database if there is an online presence in the database. If you monitor the channel ID of the device, the online monitoring device logs in successfully at this level and then continues to send login information to the upper level.
In addition, this monitoring method also includes a routing information synchronization method. The routing information synchronization method uses webservice technology for data transmission and synchronization.
III. Advantages of Huaping Tree Structure Monitoring System
1. The upper level can view the lower level monitoring data, while the lower level cannot view the upper level monitoring data. The peers cannot access each other's monitoring data. This permission relationship conforms to the actual organizational structure relationship, and effectively protects the data security.
2. Any primary server has problems or failures that cannot operate properly, and will not affect the monitoring of the same level or its subordinates, thereby improving the reliability of the monitoring system;
3, after using the tree-like layered communication structure, the monitoring alarm signal can be sent to the monitoring client at the corresponding level according to the alarm level, and does not need to be transmitted to all the monitoring clients, making the processing of the alarm more targeted. Reduced unnecessary management work;
4. One-way synchronization of routing information is used to achieve synchronization of routing information in the tree monitoring system and the division of hierarchical rights, which simplifies the two-way synchronization of existing routing information.
5. The simple and practical channel ID encoding method makes the structure of the tree-like monitoring system more easily expandable than the structure of the existing tree-like monitoring system.
Fourth, Huaping tree hierarchical structure monitoring system application
This hierarchical tree structure monitoring system is suitable for projects of large enterprise groups or government organizations.
1. Large and medium-sized service-oriented enterprises need to establish a large-scale networked video surveillance system covering corporate headquarters, provincial subsidiaries, municipal branches, county-level subsidiaries, and all operating stores.
2. Large and medium-sized production enterprises need to establish a large-scale networked video surveillance system covering all office locations and production lines in the country.
3. Provincial and municipal public security and fire protection departments need to implement multimedia video communication from the province's municipal, county, district public security bureaus, and even street police stations, including the realization of large-scale networking applications for all surveillance image resources and establishing a coverage system. The province, city, county, district public security bureau and street police station video surveillance and video conference system.
4. Banks, securities, industry and commerce, taxation, safety supervision and other departments need to establish a large-scale video surveillance system covering provinces, cities, and counties.
