Introduction: The Internet of Things is a new wave of informatization in the world's information industry following the computer, Internet, and mobile communication networks. It applies information technology more comprehensively and deeply into everyday life and production services. It is a major upgrade of information systems. The development and application prospects are huge. How the security industry seizes opportunities, expands the industrial field, upgrades the technological level, expands the development space, and achieves the effective integration of the Internet of Things and the security industry is a real problem that every security company needs to face and urgently solve.
Security industry can be divided into video surveillance, burglar alarm, access control card, building intercom and other parts, all related to the application of sensor technology, such as: video surveillance is mainly CCD or CMOS sensor technology, alarm is mainly infrared sensor technology, access control card main Is RFID technology, so the security industry and the Internet of things have a strong integration. Therefore, smart cities start from the Internet has a very high degree of plasticity.
The Smart Safe City solution is designed from the following five levels: smart perception, intelligent network, intelligent processing, smart application, and smart operation:
(1) Wisdom perception: make full use of high-definition video cameras, multiple wireless sensor systems, and video intelligent analysis technologies, and use smart and diverse sensing methods to sense;
(2) Wisdom network: Make full use of the Internet, 3G wireless network, video private network, and extranet of government affairs to form a wide range of interconnection and interoperability on the premise of security protection;
(3) Processing of intelligence: Based on full information sharing, conduct multi-dimensional information collection and integration, and develop data mining and analysis application system based on big data processing;
(4) The application of intelligence: The provision of practical applications based on task coordination, such as criminal investigation, command and dispatch, traffic management, and various applications and tools for the major needs of finance, campus, building, energy, and judiciary, greatly improving the system s efficiency;
(5) Smart operation: Optimize operation mechanism, train professional talents, maintain efficient and stable operation of the system, introduce marketization mechanism, change passively into initiative, build and share, and form advanced operation management mechanism and long-term driving mechanism.
The overall technical architecture of the smart and safe city is built using the architecture of the Internet of Things. We design from the four levels of perception, transmission, knowledge, and use of high-definition video surveillance, high-definition bayonet, electronic gamma, face capture system, and alarm sensors. , RFID, and other sensors, to achieve a comprehensive collection of information on urban roads, important areas, sensitive areas, residential areas, traffic bayonet, etc., can be seen from the see.
