Guide: The original "Police Big Data Platform Construction Plan PPT" (see the end of the article for the source), this article selects the essence and structure part, with clear logic and complete content, providing a reference for quickly forming a pre-sales plan.
Construction goals - Vigorously implement the public security big data strategy, focus on building data policing, and building smart public security
Promote the transformation of the quality, efficiency, and motivation of public security work, and comprehensively enhance the core combat effectiveness of public security organs.
Cut out the complicated and simplify, be innovative, and ensure that the technology is advanced and easy to use. The overall level must reach the national upper-middle level, and the application of some projects must reach the national advanced level.
Video Network System
The backbone network of the video private network is divided into several ring network deployments according to the links of the operators. The two core switches of the municipal office are located at the core layer of the network; some branch offices each have two sub-office aggregation switches and two core switches of the city office to form ring network 1; The sub-office aggregation switch and the two core switches of the city bureau form the second ring network, and so on, multiple ring networks form the entire backbone network.
The convergence layer of the video private network is composed of various sub-bureaus of the Municipal Bureau. Each aggregation layer site adds two aggregation switches, which form two ring networks with the two core switches of the municipal office, as the backbone network of the video surveillance project.
Social resources can be accessed through the Internet. This part of the video is accessed through the Internet and enters the border firewall through the traffic cleaning device. After the firewall passes, it enters the core equipment of the outreach access platform. The outreach access platform uploads the video to the data center network through the firewall. Provide social video resources for business platforms.
