The present application claims right of priority of the Chinese patent application No. 201710608130.7 filed on Jul. 24, 2017, the entire disclosure of which is incorporated herein by reference.
The disclosure relates to the field of vehicle networking, particularly to a street lamp integration device, a street lamp system and a communication method.
The conventional definition of vehicle networking refers to a system that extracts and makes effective use of attribute information and static and dynamic information of all vehicles on an information network platform through electronic labels loaded on the vehicles by means of the identification technology such as RF, and performs effective monitoring to running states of all vehicles based on different functional requirements and provides comprehensive services. With the development of the vehicle networking technology and industry, the above definition is no longer capable of covering all contents of vehicle networking. According to the definition of Strategic Alliance of Technology Innovation of Vehicle Networking Industry, the vehicle networking is a large system network that takes in-vehicle network, the inter-vehicle network and the vehicular mobile internet as the basis and performs wireless communication and information interchange between vehicle-X (X: vehicle, road, pedestrian and internet etc.) according to the stipulated communication protocols and data interaction standards, is an integrated network that can realize intelligent traffic management, intelligent dynamic information service and vehicle intelligent control, and is a typical application of the technology of internet of things in the field of the traffic system.
