Vehicle-mounted communication system based on WAVE

Abstract

The invention discloses a vehicle-mounted communication system based on a WAVE. The vehicle-mounted communication system comprises a first external device, a second external device, a WAVE protocol stack, an expansion interface, a road-side unit and an on-chip unit which is installed on a vehicle. The first external device, the road-side unit, the WAVE protocol stack, the expansion interface, the on-chip unit and the second external device are connected in turn. A WAVE standard coverage region is formed by connecting the road-side unit, the on-chip unit and the WAVE protocol stack. The WAVE is adopted by the vehicle-mounted communication system, a safe vehicular ad hoc network which has wide coverage range, high quality and support for multimedia information is established. Besides, disposition is easier, cost is lower and angle of business mode is further met.

Description

technical field [0001] The invention relates to a vehicle communication system based on WAVE. Background technique [0002] In recent years, with the popularization of the automobile industry, the rapid increase of private car ownership, the increasingly serious road congestion, the frequent occurrence of traffic accidents, and the continuous emergence of various vehicle-mounted devices, research in the field of vehicle-mounted communication has attracted great attention. s concern. The traditional vehicle communication network is usually only a closed communication network designed for highway billing and other purposes. Recent developments enable vehicles to support autonomous communication between workshops to exchange safety information. However, due to defects in the network architecture, the original system can only provide information interaction in a local area for high-speed vehicles, and cannot realize real-time data services between vehicles and intelligent traff...

Problems solved by technology

However, due to the defects in the network architecture, the original system can only provide information interaction in a local area for high-speed vehicles, and cannot realize real-time data services between vehicles and intelligent traffic control centers and access to broadband wireless networks

From the perspective of vehicle wireless access technology, the vast majority of vehicle mobile communication network research is based on IEEE 802.11 communication technology. Weak support, the weakness of not being able to provide high-quality support for multimedia information
