With reference to figure 2, radio data network comprises the server part.This IP-based data network is responsible between vehicle and server and from the vehicle-to-vehicle communication data.For example, this network is used to transmit the data of different types that comprises voice, text, figure and animation etc.
Can also central server be divided into some assemblies according to needed function.For example, can there be the independent communication server, displaying contents server, fleet management's server and the webserver.
Terminal allows the user to come control system by being connected to central server.Terminal can be partly based on control center, or by Internet connection.
Typically, vehicle can be taxicar or the city motor bus that travels on metropolitan public way.For example, little " smart box " can be installed in each vehicle, and has been integrated multiple function, is installed in then in the vehicle or on the vehicle.These comprise wireless communication system, data memory, position fixing system, vehicle sensors and the control of indoor/outdoor display panel etc.
Now, will be described some typical application situations.
Fig. 3 has described the scene that taxicar should need, and wherein the passenger call operating personal of regional A is so that ask a taxicar.Operating personal uses " fleet management system " to select near taxicar available and that can set out on a journey at once.Then, by using the location-based broadcasting of " voice communication system ", operating personal is broadcast to all selecteed taxicares with this new work, and opens the voice channel of all selecteed taxicares so that await a response.One of driver responds operating personal by multi-link voice channel, thereby obtains this part work.Operating personal is responded the passenger and is scheduled to confirm, and the time of advent of suggestion estimation.When taxicar arrives, the passenger can identify by the demonstration on its outside display panel and hire a car-for example " Mr. Wang please ".
By using the location information in " fleet management system ", operating personal can be known the position of each vehicle at once, searches the time thereby shortened vehicle.
Avoided unnecessary voice interruption.By using location-based voice broadcast service, only the selected driver who locatees at particular task can receive voice messaging.Unaccommodated driver does not know this part work, because do not inform them.This has minimized voice channel pollution-maintenance channel " totally ", and voice communication increases unnecessary trouble can for the N/R driver.
By means of the vehicle roof display panel that client's identification (if requested words) is shown, customer service is hommization more.But this can also prevent correct client and not call a taxi and want to take place between the passenger by bus the possibility of quarrel.
Fig. 4 is used to describe location-based content display platform.In this scene, introduced location-based content and shown notion.By using display panel on top, can show such as government's bulletin and advertisement content based on vehicle location.For example, in national park areas, can show the information that specific safety is gone on a hike.
In a scene, near the traffic congestion of highway in the ensuing several hrs traffic accident that has just taken place in regional A causes.The government representative can visit system by terminal.Can from the Vehicular system of regional A and area B, obtain time slot.The government representative can indicating area A vehicle show " avoiding the path " message, and the vehicle among the B of indicating area shows " avoiding regional A " message.After receiving instruction, server can be determined target vehicle, and the transmission proper data is used for showing immediately.
The advantage of above-mentioned instant content download system is: can immediately message be broadcast to the target area.Download message every now and then is so that keep the circulation of flow of information.
Simultaneously location-based message can be sent to zones of different.Therefore, can be separately and control traffic in the zones of different simultaneously.
In another scene, can show the material of distribution.For example, may have the demonstration that remains among the regional A.By impelling the demonstration at the taxicar top of regional A, advertising company can attract more instant participant.After receiving instruction, server can be determined target vehicle, and only data is sent to those vehicles.
The advantage of above-mentioned scene is to have cost-benefit advertisement.That is, in the incident of price rebate, the marketing personal as target, is used to the accidental person impulsive on the scene who appears at this zone to be full of at last available seat, and does not need to spend more money to carry out large-scale advertisement.
A kind of anti-robbery system has been described among Fig. 5.In this scene, unfortunate vehicle A is plundered.Driver A has supressed danger button, and the SOS signal is transferred to central server immediately.Then, the voice communication channel of unlatching and server, the dialogue of vehicle interior can serviced device record like this.On top panel, show SOS message, so that near pedestrian's attention attracting.The operating personal that receives the monitor station place of SOS signal can be listened to the dialogue that receives by voice channel.Simultaneously, the position of monitoring vehicle, and report to the police.When receiving hijack report, the police can be connected through the internet to intelligence system, and when other police of scheduling arrive in this position, monitors this vehicle.
The wireless communication network is the core component of system.By using " mixed mode ", realize enough bandwidth at the transmission of text, voice, figure and film editing in the mode of economy.For example, can dispose the central network topologies structure of low bandwidth to middle bandwidth (being 300Kps), in this central network topologies structure, all nodes all are connected to central server.This topological structure can be online all the time, and large-scale covering is provided.This can replenish by the peer to peer topology structure of high bandwidth (being 10Mps).When having only another node of existence or finding node nearby, self-organizing network is just available.The efficient range of this topological structure may have only hundreds of rice.
Fig. 6 has described the comprehensive of two network topology structures.Dotted line is represented central network, and realizes the expression peer-to-peer network.The different application of this system can be avoided one or two network-depend on maximum delay of required bandwidth, speed of transmission and permission.
Control signal communication is included in and sends signal-mainly be between vehicle unit and the server and be used to the purpose of monitoring and managing.Central network can be the suitable selection at such data transmission.
By using the VOIP technology, can come transferring voice by packet network, thereby utilize Internet resources better." open all the time " feature can be the key element of voice communication.In addition, main " central network " topological structure that centers on constitutes voice communication.Yet voice communication can obtain benefit to a certain degree from peer-to-peer network.For example, in crowded city, be not difficult to locate adjacent node, and central server is adapted to and this is held/compensate such as Hong Kong.
When news broadcast is carried out in the specific region, central server at first selects in the node some as main node, rather than sets up and being connected of all nodes.Foundation is connected with these main node.In next stage, the further foundation of these main node is connected with near node.Therefore, all nodes in the specific region are connected into network, and go on the air.
Should be understood that when mobile, vehicle node is not fixed in a position to vehicle in broadcasting process.Because the reciprocity bonded assembly vehicle of this use can shift out the scope of main node, thereby causes transmission loss.For this reason, node itself can merge intelligently, so that the connection that prediction loses, and switch connection mode thus.Here there are two options to use.Switching can be returned near another main node, if can find near the main node.If not all right, then set up and being connected of central server.
In Fig. 7, respectively regional A, B and C are carried out news broadcast.Central server at first selects in the node some as main node.For example, select node 1 and 2 at regional A.Set up and those being connected by the indicated node of dotted line.Then, near the node these nodes are found.For example, node 1 is found node 5 and node 6.Node 6 has also been found node 7, connects then.After all nodes in the zone all connect, can go on the air.In using this mode process, the work capacity of central network server descends, and still keeps real-time Transmission simultaneously.
When central server need upgrade figure shown on the vehicle or animated content, need file transfers.The representative type size of data is big (that is, 10Mb is to 100Mb) very.May not need to download to immediately on each vehicle.Preferably, half to one workaday delay is an acceptable, so peer-to-peer network can be applied to this situation.
In Fig. 8, access point AP is connected to central server by cable network.When vehicle node entered the service area of AP, file transfers began.In the drawings, node 4 enters the service area of AP1.Therefore, file is passed to node 4.By using the benefit of high speed peer-to-peer network (being 10Mbps), can transmit file apace.In next procedure, node 4 is with on the vehicle of file transfers in the field.
Should be understood that, very significantly revise for a person skilled in the art and alternately, be not considered to be beyond scope of the present invention.
