Technical Field
The invention relates to the technical field of smart city Internet of things, in particular to a smart city multistage network system based on Internet of vehicles.
Background
The development of the internet of vehicles goes through several stages, and the internet of things is called as the mobile internet of things of vehicles when the development of the internet of things is in place at the first time, people expect that the technology of the internet of things can be applied to the field of vehicles. Later, for convenience, the "car mobile Internet of things" is also called "car networking" and is denoted by the english "Internet of things", and although it corresponds to "Connected Vehicles" in the united states and "Cooperative Intelligent Transport System (C-ITS)" in the european union, and is mainly used for car/vehicle road communication to realize Cooperative application, this concept was first appeared, and more so, people were talking about it as "Telematics" (vehicle information service, which refers to vehicle computer System applying wireless communication technology), and Telematics application was already mature at that time. To better distinguish from Telematics, the industry began to use "V2X" (Vehicle to event, including Vehicle to Vehicle and Vehicle to Infrastructure, i.e., V2V and V2I) to represent the internet of vehicles more.
After the recognition of vehicle-to-vehicle communication is gradually achieved, a converged network architecture is proposed, which comprises an intra-vehicle network, an inter-vehicle network (also called inter-vehicle network), and a vehicle cloud network (also called vehicle-mounted mobile internet) for better providing communication services for an Intelligent Transportation System (ITS). With the continuous maturity of artificial intelligence and the development of intelligent driving towards higher stages, people hope to organically combine network and artificial intelligence, and make up the deficiency of autonomous perception through cooperative perception so as to better serve intelligent driving. Therefore, a new expression "smart internet automobile" begins to appear, and the smart automobile needs internet technology to provide all-around perception and also needs a network to share processing resources of the cloud. In addition, the intelligent networked automobile is not only an individual automobile, but needs to be integrated into the whole of large traffic, macroscopic traffic characteristics can affect the intelligent networked automobile, and for example, traffic congestion can prompt the automobile to avoid a congestion area in advance when a route is planned.
Although the internet of vehicles is greatly developed in the technical fields of vehicle monitoring, navigation and the like at present, the expansion of the internet of vehicles in a smart city is lack of systematicness, so that the interaction between the internet of vehicles and external information is very difficult, a driver is more dependent on a navigation system on a mobile phone for road conditions when the vehicle is driven, and the attention of the driver is reduced due to the fact that the information displayed by the mobile phone and the internet of vehicles is paid attention, so that the driving safety hazard is generated.
