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 that the power requirements of communication and information facilities can be satisfied 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 a natural loading platform for smart city IoT devices.
Thirdly, the height of the street lamp unit and the capacity of the inner 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.
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.
