In recent years, more and more security industries have begun to get involved in the "Internet of Things." In fact, the security industry, especially video surveillance, has always been the "Internet of Things" - an important part of perception, which is a study of the development and application of the Internet of Things. Bring convenience. At the same time, the Internet of Things entails huge economic value. Using the Internet of Things to transform traditional industries will certainly increase the added value of traditional industries, and effectively promote the transformation of China's economic development mode from production-driven to innovation-driven, and promote the adjustment of China's industrial structure. With the innovation of new technologies, new products, new applications, and new service modes of the Internet of Things, it will also give birth to a number of new business forms and become a new growth point for the Chinese economy.
The characteristics of the Internet of Things and its structural hierarchy
The Internet of Things refers to real-time acquisition of any need for monitoring through various information sensing devices such as sensors, radio frequency identification (RFID) technology, global positioning systems, infrared sensors, laser scanners, gas sensors, and other devices and technologies. Connected, interactive objects or processes, gathering information on their various needs such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., and formed a huge network combined with the Internet. Its purpose is to realize the connection of things and things, things and people, and all items and networks, so as to facilitate identification, management and control.
The Internet of Things has two important characteristics: First, it is scaled. Only when it has scale, can the intelligence of goods be brought into full play. Second, liquidity. Items are usually not stationary. We must ensure that the goods are in motion, even at high speed. The dialogue can be achieved at any time. Of course, the Internet of Things can also be built on stationary objects such as perimeter defense, cultural relics monitoring, bridge monitoring, and environmental monitoring.
From the perspective of architecture, the Internet of Things can be divided into five layers: support layer, perception layer, transport layer, platform layer, and application layer. The support layer is first of all a complete technical support system, mainly including collaboration awareness, sample database, security, simulation, ad hoc network, and network convergence; followed by platform support on the technical system, mainly including flexible production lines and Ipv6. The main function of the perception layer is to identify objects and collect information, and provide massive and accurate data information support for subsequent information processing and corresponding decision-making behavior. The information acquisition methods of the Internet of Things's sensing layer mainly include RFID, sensors, two-dimensional codes, GPS/Beidou, and actuators, among which RFID mainly includes chips, non-contact IC cards, read/write terminals, labels, middleware/software, and personalization equipment. GPS/Beidou mainly includes chips, terminals, receivers, and application systems. The actuators mainly include micromotors and artificial muscles. The transmission layer mainly includes optical transmission and communication and network equipment, in which the optical transmission mainly includes optical fiber cables, optical devices, optical access devices, and optical transmission devices, and the communication and network devices mainly include 3G/B3G, NFC, ZigBee, Bluetooth, and Wi-. Fi/WAPI, M2M. The main function of the platform layer is to carry all kinds of applications and to promote the transformation of its achievements. The platform layer industry chain includes support software, computing center and SI, among which the support software mainly includes embedded software, SOA, pattern recognition, data mining/BI, and the computing center mainly includes cloud computing center and super-computing center. The application layer starts from the specific needs of all aspects of the national economy and social development, combines the characteristics of the industry, and forms the IoT application branch with obvious industrial characteristics through the application of the Internet of Things technology. It eventually forms the Internet of Things that involves people’s daily learning, work, and all aspects. Application collection. The application layer industrial chain includes intelligent industry, intelligent agriculture, intelligent logistics, intelligent transportation, smart grid, smart environmental protection, intelligent security, smart medical, smart home, intelligent building, intelligent finance and so on.
Developing the Internet of Things Industry to Become a National Development Strategy
The concept of the Internet of Things was first proposed by Professor Ashton of the MIT Auto-ID Center in 1999, and was officially released at the International Conference on Mobile Computing and Networks held in the United States. Prof. Ashton proposed a solution combining item coding, RFID, and Internet technologies. At that time, based on the Internet, RFID technology, and EPC standards, on the basis of the computer Internet, using radio frequency identification technology, unlimited data communication technology, etc., a global product was constructed. The Internet of Things "Internet of Things," which is a real-time sharing of information.
Since 2006, China has successively introduced a series of IoT industrial policies and plans: In April 2008, the National Wireless Sensor Network Standardization Working Group was established; in November 2008, the Ministry of Industry and Information Technology released the “Information Industry Technology Developmentâ€. V. Plan and Medium and Long-Term Plan for 2020 (Outline); in October 2010, the State Council issued the "Decision on Accelerating the Cultivation and Development of Strategic Emerging Industries"; on February 14, 2012, the Ministry of Industry and Information Technology officially released The Twelfth Five-Year Development Plan for the Internet of Things; July 9, 2012, the “Twelfth Five-Year Plan for National Strategic Emerging Industries Development†issued by the State Council lists Internet of Things as a key development direction for the new generation of information technology industry; At the end of August 2012, the State Council approved the establishment of the "Inter-ministerial Joint Conference on the Development of the Internet of Things" mechanism; on February 17, 2013, the State Council officially issued the "Guiding Opinions on Promoting the Orderly and Healthy Development of the Internet of Things," and proposed that by 2015, it must be realized. The demonstration and application of the Internet of Things in important areas of economic society, breaking through a number of core technologies, and gradually forming the Internet of Things industry system, the ability to safeguard security Increase.
