Building "Green City" building a harmonious society help – monitoring
"Green City" project is a large, integrated management system is very strong, he involves many factors, not only to meet the security management, urban management, traffic management, emergency command and other needs, but also take into account disaster accident warning, monitoring safety aspects of video surveillance needs. It is not only a common monitoring system, but also the alarm, access control and other supporting systems and broadcast systems integration and linkage. To this end, we have established the following design ideas:
A guiding ideology 1. Adhere to technology to police the "Golden Shield Project" guidelines.
2. Strictly follow the "Security and Protection Technical Specification" (GB50348-2004) and the Ministry of Public Security guiding the 3111 project file.
3. Master Plan, the main building, step by step, sustainable development, gradually improved.
II construction principle Unified planning, unified standards and construction, and management
Third, management principles Classification responsible for overall coordination, unity of command
IV building objectives Built a highly scalable, high reliability, high security, high fault tolerance and reasonable cost structure of urban linkage and emergency system platform.
5, construction technology programs (1) design ideas A modern, comprehensive urban public safety monitoring system, should strictly follow the "Security and Protection Technical Specification" (GB 50348-2004) and the Ministry of Public Security of the 3111 documents guiding the project design and implementation.
Full consideration and use of existing alarm systems and video surveillance systems and transmission resources, integration of resources, the public security law and order and social dimensions of video surveillance video surveillance resources, adhere to the principle of combining old and new, to achieve resource integration, interoperability, information sharing.
Use of special network security video, video networks at all levels of Government Administration and the Internet as a medium of network connections for security, government, emergency services command center and various functional departments.
(B) system structure With classification management principles, in accordance with the municipal, district, street (town) level, the unit of administrative division of the rules, Safe City Monitoring System consists of four parts: the control points, monitoring points, sub-centers under the jurisdiction of police station Public Security Branch, Centre, Centre for Urban total.
Figure 5-1 From Figure 5-1, this system generally by the monitoring network, transmission channels and control center composed of three parts, of which Council is divided into three control center control center, monitoring center branch 2 and the police station a monitoring center.
This system is a typical multi-level system, characterized by a pyramid structure, the city command center spire is the Municipal Public Security Bureau, Municipal Public Security Bureau command center, not only responsible for the management of the Public Security Bureau , but also traffic management center, the industry should be included in the unified management of security, and even such important units of key units and security management can be integrated into the centralized dispatch center management Council; stations and other important units of the middle tower layer, base layer is the station control center, monitoring center is vertical at all levels of management.
Police station location in the city with the characteristics of dispersion, so that it can collect information network across the city, sending up the information and then step by step, to share information at all levels of the monitoring center, unified scheduling purpose.
The main receiving station monitoring center under the jurisdiction of its monitoring points, access methods are coaxial cable, fiber optic, wireless, Internet access and so on.
Branch monitoring center over the main receiving station for video signal transmission and its control point to the direct control of the police station by way of the video signal transmission network over, but the direct control of the control point by coaxial cable , wireless devices or optical fiber cable directly to the sub-monitoring center.
Council to receive sub-transmission control center over the main video signal and its direct control of the control point to the same, branch to the Urban transmission signal is transmitted through the network over network security professionals, direct control monitoring point by coaxial cable, fiber optic cable or wireless transmission equipment, access.
