1. The problems faced by the chain supermarket monitoring system
1. How to achieve optimized management of large systems?
The construction of chain supermarkets involves various social resource access modes. Monitoring points are spread throughout the city, and the number of monitoring points and users is huge. How to effectively manage these resources and realize the reasonable arrangement and management of the system is a key. Tiandiweiye’s industry solutions put forward the concept of grouping. The system first classifies various resources into groups to form user groups and equipment groups. Permission mapping management is carried out between device groups and user groups. Anyone’s operations on any device will follow the guidelines of permission management. Such a large system is divided into several small systems, each domain administrator is only responsible for the management tasks of the subsystem, and does not have to concern the layout of the entire system, which effectively reduces the complexity of system management and realizes Optimized management of large-scale systems.
2. How to respond to many users’ operations on the system?
Faced with such a huge monitoring system of a large supermarket chain, which may involve hundreds of users, how the system responds to the operations of these users is of vital importance to the safety of the system. Tiandi Weiye Industry Solutions provides 4 user rights management modes, and is equipped with a powerful log recording function, which can meet various user rights requirements and retain detailed operation log records. This is very helpful for system recovery and locating problems. .
3. How to solve the problem of system expansion?
A system such as a large supermarket chain is difficult to complete at one time, and it often takes several rounds of construction to establish it. How to solve the problem of continuous expansion of the system is very important to the integrity of the system. Tiandiwei’s industry solution adopts a tree-type directory management model. Each monitoring domain is equipped with a database and proxy forwarding server, and at the same time, it completes the local data and management and realizes the cascade with the system. As shown below:
In this way, when the system is expanded, it only adds a record in a certain database in the system, without any impact on the structure of the system. The expansion of the system brings only a fuller tree, and the system maintains integrity and transparent management. The simplicity.
4. How to solve the problem of mass storage?
According to the spirit of the public security system’s safe city construction, the system should have the ability to store video for 30 days.
For chain stores on key road sections, 24-hour video recording is required. How to solve the problem of video file storage is related to the application value of the system. Tiandi Weiye’s industry solution adopts the design concept of distributed video recording. Centralized video recording hosts are set up in each secondary monitoring center, and each center is only responsible for recording the video recording tasks of the monitoring points in the area. The recording capacity of each recording host can reach 200 channels. It adopts storage modes such as extended disk array or IP SAN, and has a hot backup function. When the third-level monitoring center and other users need to perform video playback, the video-on-demand system can transparently realize online playback or download of video files.
5. How to realize the effective management of monitoring and alarming?
In addition to video surveillance, a large chain supermarket monitoring system also needs to process a large amount of alarm information, how to be effective
Making use of this information in a timely manner is essential to discover and deal with problems in a timely manner. Tiandiweiye’s industry solutions provide the function of dual-screen display of electronic maps. In the electronic map display, the user can select a monitoring point at will to display it on another monitor. At the same time, users can also obtain real-time alarm information on the electronic map, and accurately locate the alarm location.
6. How to share monitoring resources?
In order to allow more users to conveniently use the system anywhere, Tiandiweiye Industry Solutions
Two application modes, C/S and B/S, are provided. The C/S application mode provides users with a functionally-rich and good man-machine interface, while B/S provides users with a simple access mode, especially for users on business trips, they can log in to the system directly through the IE browser to export. , Enjoy system services anytime, anywhere. At the same time, the proxy forwarding server of the system realizes the access of the public network and the local area network, not only does not occupy the IP resources of the public network, but also ensures the security of the monitoring network.
2. System architecture
Tiandiweiye large chain supermarket monitoring system adopts a hierarchical structure. As shown in the figure below: the system is divided into three levels, chain supermarkets are level one monitoring; police stations and chain branches are level two monitoring; municipal bureau and chain headquarters are level three monitoring centers. Each area forms a small monitoring subsystem, the secondary monitoring center provides forwarding services to the municipal bureau through the proxy server, and each system maintains information synchronization through the database.
System composition

1. The front-end monitoring points are all transmitted through the network, that is, using a network integrated ball or a camera plus a network video server, the analog video signal and control signal are digitally coded and transmitted to the police station monitoring center through the network. At the same time, each chain store needs to configure a monitoring host for local monitoring and management.
2. The secondary monitoring center uniformly deploys the video server, video management server, digital center matrix, etc. according to the specific situation. Among them, the video server completes the centralized video recording task of the center, and the digital center matrix is responsible for the functions of video management, sharing and control, and reverse decoding on the screen wall.
3. The third-level monitoring center is equipped with a VOD on-demand system, which can achieve transparent access to the video files of each police station. At the same time, WEB service function will also provide WEB access function for users in the system, including public network users can also access the entire system through IE browser.
3. System advantages
1. Flexible system construction. It can use the existing optical cable, the existing dedicated line network, and the public broadband network and the public security dedicated network to transmit the audio, video, control, and alarm signals of the front-end monitoring point to the higher-level monitoring center in analog and digital ways.
