Description
Technical field
The present invention relates to vehicular communication equipment field, particularly to a kind of inter-vehicular communication method and system.Additionally, this communication means and system are particularly suitable for application as supplementing and upgrading of current vehicle multimedia system.
Background technology
Radio communication is a kind of communication mode that the characteristic utilizing electromagnetic wave signal to propagate in free space carries out information exchange, and in recent years in the information communications field, with fastest developing speed, most widely used is exactly wireless communication technology.The radio communication realized in movement is commonly referred to as again mobile communication, and people are collectively referred to as wireless mobile communications the two.Radio communication between vehicle falls within this type of.
Vehicle communication network is exactly loading mobile communication equipment on automobile, the broadband wireless access mode of a kind of two-forty is provided for the vehicle in running at high speed, build the huge wireless Internet of Things that is carrier with vehicle, including each parts of vehicle interior, cordless communication network etc. between vehicle and vehicle, between vehicle and roadside base station.Dividing according to communication distance, vehicle communication network mainly includes car territory net (VAN) and the big class of car self-organization network (VANET) two.Car territory net refers to by using sensor, electronic tag etc., builds WLAN, and accessed the wireless wide area network of periphery by car borne gateway between the mobile each parts of vehicle interior.It can make vehicle interior and equipment around directly or indirectly be communicated by wireless protocols.The mobile ad-hoc network (MANET) application on traffic route is referred to as car self-organization network, it be high-speed motion vehicle between and run vehicle on a highway and provide a kind of possible high-rate wireless communication access way.
Universal along with private car, it is more and more that automobile friends gang that self driving goes on a tour.In order to ensure the liaison in advancing, the demand of radio set (be divided into hand-held radio station, be called for short transmitter receiver or hands platform and vehicular radio station, be called for short ride two kinds) is just mentioned on desktop.But RF resources is limited, country is for buying and using radio set to suffer from strict regulation.
Summary of the invention
Therefore, the present invention provides a kind of inter-vehicular communication method and system, its object is to: realizing a kind of liaison method forming into columns when driving between vehicle, this wireless communications method can freely be convenient to use, and can provide the information interactive function between vehicle for miscellaneous equipment and program.
The present invention can be installed in car as independent system and use, it is possible to merges and embeds inside in-vehicle multi-media system, as a New function.
A kind of inter-vehicular communication method and system step in the present invention: occupant's open communication system, wireless module broadcast self information also searches for other information of vehicles in communication context, occupant selects need the vehicle of communication and apply for connecting, after being applied connection vehicle granting an application, system uses pick up and photographic head to catch user voice and image passes to opponent vehicle, opponent vehicle is play and shows the sound and image that receive, simultaneously by the sound of the other side and image be passed back, the sound of this car system plays and display reception and image, this wireless network can also be used between vehicle to transmit mutually the data of miscellaneous equipment or program, its flow process is as shown in Figure 1.
Vehicle use wireless network be government allow safety, based on common frequency band or other non-government management and control type.Self independent control button or touch screen can be used when communication system implements to be controlled, it is possible to use the control method that in-vehicle multi-media system shares controls or other effective means.
The pickup module that communication system uses clearly should be able to catch occupant's sound effectively, the work that communication system should be able to effectively complete noise reduction and compressed encoding transmits in time.The image capture module that communication system uses clearly should be able to catch occupant's image effectively, the work that communication system should be able to effectively complete image acquisition and compressed encoding transmits in time.The sound broadcasting module that communication system uses should be able to clearly play the sound received, and communication system should be able to have timely completed the decoding effort of the voice data received.The image display that communication system uses should be able to clearly display the image received, and communication system should be able to have timely completed the decoding effort of the view data received.
Self independent loudspeaker can be used when sound broadcasting module implements, it is possible to use in-vehicle multi-media system share sound system or other effective means.Liquid crystal display screen can be used, it is possible to use vehicle-mounted head-up display, projector or other effective means when image display implements.
The wireless module that system uses should have certain remote big bandwidth communication ability, simultaneously when spaces of vehicles quickly dynamically changes, is still provided that stable wireless connections.
More excellent, in the method and system, communication system should be able to, using self as a wireless network hop, be front and back car relay forwarding communication datas automatically, to strengthen the communication stability between the car of front and back, extend the communication context of whole vehicle team simultaneously and strengthen communication stability.
More excellent, the method and the antenna assembly that uses in system should automatic orientation transmitting/receiving wireless signals, in order to reduce interference from each other further, can greatly increase communication distance and signal intensity simultaneously.Automatic orientation function refers to when communication object concentrates on certain direction, and antenna assembly only should be launched wireless signal towards the direction and only receive the wireless signal that the direction transmits.Can using multiple antenna when automatic orientation function implements, the signal transmitting and receiving of different directions is responsible for by each antenna, it is possible to use single antenna with automatic cradle head or other effective means.
More excellent, the method with system should be supported many vehicles are networked simultaneously communicate simultaneously, to meet the demand of group's exchange.
The technique effect obtained after the present invention is adopted to be: to achieve a kind of liaison method forming into columns when driving between vehicle, provide cordless communication network for the equipment between vehicle and program, solve the trip of tradition fleet and use the limited awkward problem of intercom function.
