Since the Ministry of Housing and Urban-Rural Development proposed the construction of a smart city in 2012, the market size of smart cities has increased year by year, and “smart cities†have become a hot word. What is a smart city? Generally speaking, the smart city refers to: First, a highly informatized modern city; Second, relying on mature, systematic and perfect information and communication technologies. Third, the essence of a smart city is to make the city's management and operation more conscious and more refined, and thus create a better life for the people in the city and promote the harmonious and sustainable growth of the city. Some functions of smart city The smart city technology system is divided into four levels: application layer, platform layer, network layer and sensing layer. The application layer includes emergency intelligence, digital urban management, safe city, smart transportation, convenient service, environmental monitoring and energy saving control; platform layer refers to IOT platform and data platform, which realizes intelligence through platform; network layer refers to communication network, internet and Internet of Things; The perception layer includes mobile phones, PCs, Internet, cloud computing, wireless APs, cameras, environmental hosts, and one-button alarms. Smart city technology system With the construction of smart cities and the increasing popularity of the Internet of Things, smart street lights are an important and indispensable entry point for smart cities, and more and more appear in cities. So, how is the value of the streetlight system in a smart city? It can be discussed from four aspects. First of all, street lights and their systems have a natural information perception and feedback platform in smart cities. Urban street lights have a complete and independent power supply system. Because of its unbalanced use characteristics, the margin is sufficient, so that the power demand of communication and information facilities can be met without laying cables. Street lamp power supply system Second, the network-like distribution is one of the biggest features of street lighting layout. As the density of the network increases, the characteristics of the network distribution will become more obvious and reasonable, and the dead angle will gradually disappear. The networked distribution of communication and information facilities without dead ends is the basic condition for realizing full coverage of smart city information. Among all municipal facilities, only the streetlight system can achieve a networked distribution without dead ends, so it is a natural platform for smart Internet IoT devices. Network-like streetlights and real scenes Again, the height and lumen capacity of the streetlight unit is sufficient to carry enough, increasingly small, and streamlined communications and information equipment under the integrated design requirements. The street lamp structure has three basic components: a rod, a seat and an arm. In a customized street lamp, there is usually a structurally unique body. The large capacity of the lamp holder and the main body is self-evident, that is, the lamp post and the lamp arm can also be loaded with communication and information equipment by a reasonable design without affecting the beauty of the appearance. Structural design of street lighting loading communication and information equipment in a city The last point is that the operation and maintenance system of the street lamp system is ready-made, perfect and professional, which provides a guarantee for the operation of the smart city. Operation and maintenance of smart street lamps In short, the street lamp is a public product provided by the government and has good sharing conditions. Although its primary function is to ensure road traffic safety and public security, but because of the wide variety of road lamps, global coverage, system independence, self-contained system, independent electric drive characteristics, and maintenance team professional, fault handling in a timely manner, therefore, street lights Today, it is not a single municipal facility that provides lighting functions, but a carrier of several functional systems in urban space. Therefore, the lack of street lights in the smart city system can not be said to be a complete smart city. Ningbo Autrends International Trade Co.,Ltd. , https://www.ecigarettevapepods.com
