The intelligent security integrated management platform aims at the highest requirements of the industry at the beginning of R&D, spent nearly one year to fully investigate the needs of different industries and users, and combined fifteen years of development experience of large and medium-sized system integration software. , Breakthrough R&D on the core technology of the security management platform, and introduced core technologies such as parallel domain architecture, multi-level pyramid index architecture, virtual storage stripes, N+M backup strategy, etc. into the management platform system to solve the security management platform Interconnection, second-level retrieval of massive data, system smooth upgrades, carrier-grade security and reliability, and other user needs.
1. Multi-level Pyramid Index Architecture The intelligent security integrated management platform adopts a multi-level pyramid super index mode. Through the three-level index mode of database, storage server, and file, combined with ASMF file technology, any camera, video image at any time can be realized. Super-response speed of seconds playback. When the multi-level pyramid super index mode is positioned, layer-by-layer segmented query access is used to quickly determine any frames and video segments in the file without analyzing the entire index, which greatly improves the file positioning and response speed; ASMF files Fully independent of the operating system, direct read and write operations on the disk, with high I / O read and write performance, in Shanghai Pudong HD project, more than 12,000 high-definition cameras, 15-day storage capacity, 20PB data retrieval to achieve second-level retrieval Playback has been unanimously affirmed by the user.
2. Infinitely Expanded Virtual Storage Stripe Technology The intelligent security integrated management platform provides virtual storage striping technology. The so-called virtual storage striping technology uses precise accounting to store a certain amount of cameras, storage units with corresponding capacity, and storage streams. The media servers are linked to form a basic unit. This basic unit is a virtual storage stripe. The virtual storage strips can be expanded indefinitely to meet the seamless expansion of monitoring and monitoring systems, and can support seamlessly from tens of roads to tens of thousands of cameras. To build a large-scale, super-large monitoring system, virtual storage strips are both relatively independent and managed by the management platform, unified scheduling, and the effectiveness of the technology has been fully demonstrated in the Shanghai Pudong HD project.
3. Highly reliable N+M backup mechanism The most critical security system is stability, never black screen, intelligent security integrated management platform to take a variety of security, reliability design, to ensure the reliability of the management center: to achieve a distributed system through the parallel domain architecture Each parallel domain can operate independently, and multiple parallel domains can manage data synchronously with each other to achieve unified management in phases. Key components in the system, such as streaming media servers and storage arrays, are configured with a minimum redundancy of N+M to ensure that when the streaming media server and the storage array fail, backup devices can immediately take over, and the core management server adopts dual-server real-time hot backup. . In the event of a database failure relying on local indexes to ensure that data is not lost, power failure recovery in the event of large-scale power outages, all devices can automatically restart the recovery, a lot of security backup mechanism design, all-round protection and security monitoring system reliable operation.
4. Industrial application—integrated and innovative public security combat system The intelligent security integrated management platform is a large and medium-sized security management platform that can meet the security management needs of most industries and users. However, in the deepening applications of the industry, general-purpose large and medium-sized security The management platform cannot meet the user's industry requirements, and it needs to conduct targeted research and development of the industry.
In the “Perceived New District†project in Wuxi New District, users of Wuxi New District Public Security Bureau put forward the need to build a public security actual combat platform. Based on the video surveillance system in Wuxi New District, the video surveillance system, high-definition bayonet system, case event system, and operation and maintenance were integrated. The system's unified public security real-time platform integrates information resources such as videos, bayonet, case events, and pictures, and provides functions that meet the needs of business units for each branch of the branch, such as providing video patrol functions for police stations, surveillance rooms, and other units. It provides emergency command and on-site disposal functions for the command room, provides vehicle search, video search, collision comparison, event evaluation functions for criminal cases, provides efficient late-stage video troubleshooting tools for criminal investigation, and provides system-wide operation monitoring functions for ICT departments.
As an integrated business platform, the public security actual combat system is not a simple data collection and integration for integration, but an integrated and innovative new business platform. It conducts targeted research and development on the basis of collections and meets the case judgment and data mining of various business units. Incident management, operation and maintenance needs.
5. Industrial applications - mutual integration of rail transit monitoring system Rail transit (subway, fast rail) is the backbone of urban public transport. It has the characteristics of energy saving, land saving, large capacity, all-weather, no pollution and safety. It is a green environmental protection transportation system and meets the requirements of the national sustainable development strategy. It is particularly suitable for large and medium-sized cities. Such as Beijing Metro Changping, Fangshan, Yizhuang three subway video monitoring system, the project is a typical industrial application of video surveillance system, not only to realize the Beijing subway station simulation system centralized networking control management, and to achieve and control center of the ISCS Interoperability of third-party systems such as TCC, centralized alarm, operation control, and clock synchronization, as well as intelligent functions such as legacy items, alarms that pass through restricted areas, motion detection, personnel detention, and sudden passenger flow alarms.
