The city we live in brings us endless vigor and vitality. With the emergence of the Internet of Things, people in cities have realized that "scholar can not go out and know the world", while the Internet of Things connects the infrastructure of urban life to further reduce and flatten the world. So, someone exclaimed: We are entering the era of wisdom! Therefore, smart city came into being. The city we live in brings us endless vigor and vitality. With the emergence of the Internet of Things, people in cities have realized that "scholar can not go out and know the world", while the Internet of Things connects the infrastructure of urban life to further reduce and flatten the world. So, someone exclaimed: We are entering the era of wisdom! Therefore, smart city came into being. Four Characteristics of Smart City Construction in the Context of Internet of Things As the concept of smart city so far there is no unified conclusion, if the construction of the Internet of things for the background, we talk about smart city construction is through the Internet of Things ubiquitous sensors embedded in urban objects are connected, Realize the overall perception of the real city, the use of cloud computing and other intelligent processing technology for the perception and processing of large amounts of information to achieve online city digital space and the integration of Internet of things, and issue instructions on, including government affairs, livelihood, environment, public safety, etc. The various needs, including intelligent response and intelligent decision support. A smart city is planning the city with wisdom, building the city with wisdom, managing the city with wisdom and developing the city with wisdom so as to improve the reachability of urban space and make the city more dynamic and rapid development. The "smart city" is the further development and deepening of "digital city." Its most essential feature is the stitching together of the "digital space" of information and the "physical space" of the real city through the Internet of Things. Thus, the core of smart city construction under the IoT architecture lies in the innovation mechanism of urban innovation around the scientific concept of development and the establishment of an innovative model of harmonious development of man and economy, man and society, man and resource environment. Smart city system can be perceived layer, network layer, management and application layer, corresponding to the following four characteristics: (1) a more thorough perception: the use of any can feel, measure, capture and transmit information anytime, anywhere devices, systems Or process Quick access to any city information and analysis, to facilitate immediate response and long-term planning. (2) Wider Interoperability: Connect, interact and share information and data collected and stored in personal electronic devices, organizations and government information systems through various forms of high-speed and high-bandwidth communication network tools Environment and business conditions of real-time monitoring, from a global perspective to analyze the situation and solve problems in real time, making the work and tasks can be completed through a multi-party collaboration to change the operation of the entire city. (3) Safer City Management: Under the new generation of information platform with deep awareness and interoperability, urban management should be more secure, give due consideration to citizen's adaptability and satisfaction, and provide smart security solutions. (4) Further Intelligence: In-depth analysis of the data collected to obtain more innovative, systematic and comprehensive insights to solve specific problems to better support urban development decisions and actions. Application of Internet of Things Technology in Smart City Construction Smart city construction is encompassing everything from the point of view of the Internet of things to its application in smart cities. There are several aspects that are greatly related to our security industry: Redefine Safe City Content with IoT In the security industry, as a safe city for smart city construction and based on IoT technology, we will revisit and locate the safe city construction. From the business system, technology structure, operation mechanism, relationship between government and society in the safe city , Operation and maintenance management, operation and service, construction methods, etc. can be innovative. As mentioned before, there are four major characteristics of smart city construction under the IoT architecture, all of which can be reflected in the safe city. Safe city with IoT technology, we can do top-level design from smart perception, intelligent network, intelligent processing, intelligent application and intelligent operation: Wisdom perception: Take full advantage of high-definition video surveillance, a variety of wireless sensor devices, video intelligence analysis technology, using the wisdom of a variety of means of perception to collect data. Wisdom network: Internet of Things, Internet of things, 4G, video private network, government and other networks outside the network, you can secure the interconnection of cities. Wisdom processing: On the basis of full sharing of sensing information, multi-dimensional information collection and fusion, development of data mining and analysis application system based on big data to meet the multi-industry applications under the smart city. The application of wisdom: to provide the basic tasks of collaborative real-world applications, such as criminal investigation, command and control, traffic management and finance, campus, building, justice, and other industries based products and systems, substantially improve the efficiency of project construction. Intelligent operation: Optimize operation mechanism, cultivate professional team, maintain efficient operation of the system, introduce market-oriented mechanism, change from passive to active, build and share, forming a long-term and effective management mechanism for safe cities under IoT technology. Internet of Things technology in intelligent transport of mature applications In the intelligent transportation industry, it can be said that IoT technology is the most mature application in smart city construction. Because of the traffic management part of the smart city construction expectations are: the National Intelligent Transportation System Framework as a guide, to build "efficient, safe, environmentally friendly, comfortable and civilized" intelligent transportation and transport system, significantly improve the management of urban transport system Level and operational efficiency. Provide a full range of traffic information services for travelers and convenient, efficient, fast, comfortable, economical, safe, human, intelligent and ecological transportation services; provide timely and accurate comprehensive information to traffic management agencies and related enterprises Support and information decision support. In view of the status quo of urban traffic and the existing problems, from the perspective of solving practical problems and properly looking forward, the main contents of intelligent traffic under the technology of Internet of Things include: Intelligent parking and induction system. The intelligent parking and guidance system can improve the efficiency of driver parking and reduce the traffic congestion and energy consumption caused by parking difficulties. It includes two aspects: First, to issue guidelines on the parking lot, parking space and parking route for traveling public Information to guide the driver to arrive at the designated parking area; Second, the electronic parking management to achieve the reservation of parking spaces, identification, automatic timing fees. Electronic non-stop charging system. Electronic non-stop charging system is characterized by non-stop, unmanned operation and cashless transactions, mainly includes two parts, one is the vehicle's electronic license plate system, which is the only vehicle identification, vehicle information stored, real- Station control equipment to communicate; the other part is the background billing system, the management center and the bank, including fee-charging franchisee, clearing house and customer service center, the background according to the received data files in the road toll franchise companies and users Between the transaction and settlement.
