On the Value of LED Street Light System in Smart City

Since the Ministry of Housing and Urban-Rural Development proposed to build a smart city since 2012, the market scale of smart cities has been increasing year by year, and “Smart City” has become a hot word. What is a smart city? The smart cities we usually refer to are: 1. Highly informatized modern cities; 2. Rely on mature, systematic and perfect information and communication technologies. Third, the essence of a smart city is to make the management and operation of the city more conscious and more elaborate, thus creating a better life for the people in the city and promoting the harmony and sustainable growth of the city.

Some smart city features

The smart city technology system is divided into four levels: application layer, platform layer, network layer, and perception layer. The application layer includes emergency intelligence, digital city management, safe city, smart transportation, convenience service, environmental monitoring and energy-saving control; the platform layer refers to the IOT platform and data platform, through the platform to achieve intelligence; the network layer refers to the communication network, the Internet and The Internet of Things; perception layer includes the mobile phone, PC, Internet, cloud computing, wireless AP, camera, environment host, a key alarm.

Smart City Technology System Composition

With the construction of smart cities and the increasing popularity of the Internet of Things, smart streetlights, as an important and indispensable entry point for smart cities, are also increasingly appearing in cities.

So how does the value of the street light system in a smart city be reflected in the end? You can start from four aspects.

First, street lights and their systems have natural information perception and feedback platforms in smart cities. City lights have a complete and independent power supply system. Because of its non-equilibrium use characteristics, the margin is sufficient, so it is possible to meet the power demand of communication and information facilities without laying cables.

Second, network-like distribution is one of the biggest features of street lighting layout. With the increase of road network density, the characteristics of network distribution will be more obvious and reasonable, and the dead angle will gradually disappear. The dead-end network distribution of communication and information facilities is the basic condition for full information coverage of smart cities. Among all the municipal facilities, only the street light system can achieve no dead-end network distribution. Therefore, it is the natural loading platform for smart city IoT devices.

Network distribution of street lights and real scenes

Again, the height of the street lamp unit and the capacity of the cavity are sufficient enough to carry a sufficient number of communication and information devices with increasingly smaller and smaller size under the requirements of integrated design. The street lamp structure has three basic components: a pole, a seat, and an arm. In a customized street lamp, there is usually a main body with a unique structure. The large capacity of the lamp holder and the main body is not to be forgotten, that is, the lamp pole and the lamp arm can also be loaded with communication and information equipment through rational design without affecting the beauty of its appearance.

The last point is that the operation and maintenance system of the street light system is ready-made, perfect and professional, which provides guarantee for the operation of the smart city.

Intelligent street lamp operation and maintenance

In short, street lamps are a public product provided by the government and have good sharing conditions. Although its primary function is to ensure road traffic safety and security precautions, but due to the fact that the road lighting is a little wide-ranging, global coverage, system independence, self-contained system, independent power-driven features, and the maintenance team is professional, fault handling is timely, therefore, street lamps Today, it is not a single municipal facility that provides lighting functions, but is a carrier of several functional systems in urban space. Therefore, the lack of street lights in the smart city system is not a complete smart city.
