Intelligent vehicle-mounted system

Abstract

The present invention provides an intelligent vehicle-mounted system, wherein the hardware structure comprises a central processing controller, a wireless communication module, a power module, a GPS positioning module, a storing module, an audio / video broadcasting module and a human-machine interaction module, wherein the wireless communication module, the power module, the GPS positioning module, the storing module and the audio / video broadcasting module are connected with the central processing controller. The vehicle-mounted system software mainly comprises a main interface program, GPS positioning navigation software and multimedia broadcasting software. The vehicle-mounted system and other vehicle-mounted terminal form an Ad Hoc network through the wireless communication module. The communication protocol of vehicle-mounted system adopts an Ad Hoc routing protocol based on GPS and electronic map and an MAC protocol with adjustable power. The vehicle-mounted system supports the functions of enciphering and authenticating. The vehicle-mounted system can aim at different user grades for allocating authority and executing related authentication to the user. The independent and distributed intelligent vehicle-mounted terminal system of the invention can be applied to various vehicles for realizing the interconnection, intercommunication and information sharing of Ad Hoc mode between intelligent vehicle-mounted systems and for realizing the multi-hop communication between the vehicle and the stationary platform. The intelligent vehicle-mounted system of the invention has the advantages of intelligentization, low cost, convenient use, etc.

Description

technical field [0001] The present invention relates to wireless self-organizing network technology, automobile electronic technology, embedded development technology, and in particular belongs to the technology of an intelligent vehicle system based on Ad Hoc. Background technique [0002] With the rapid development of intelligent transportation, it has become a very important research topic to ensure the safe and reliable operation of the vehicle system network and to provide network reliability and flexibility. Currently, the most commonly used communication networks are CDMA and GPRS networks. The vehicle communicates with the traffic control center through the CDMA or GPRS network, and downloads the entertainment information by connecting to the Internet. However, this centralized networking method has a fatal flaw, that is, information interaction cannot be formed between vehicles, resulting in low information sharing capabilities. This method of networking and commu...
