Fig. 1 is the structural representation of fleet of the present invention communication navigation system;
Fig. 2 is the inner concrete communication synoptic diagram of fleet of the present invention communication navigation system.
Embodiment
The present invention is a kind of fleet communication navigation system, like Fig. 1, comprises server and a plurality of vehicle-mounted client (being exemplified as vehicle-mounted customer end A, vehicle-mounted customer end B, vehicle-mounted client C).Server is except the archive information that writes down each vehicle-mounted client, and its electronic map database can be carried out the real-time update in POI, road net data storehouse.The built-in navigation module of vehicle-mounted client, display module, load module and communication module can carry out wireless telecommunications, send and receive information with server.Information interaction between the vehicle-mounted client can be carried out through mobile phone short messages except from transit server.Through above message exchange, system realizes following function.
The road network update functions.The up-to-date POI of server real-time update, road net data storehouse; And all vehicle-mounted clients will constantly be upgraded to server requests by certain time interval; Server will need data updated to be issued on each vehicle-mounted client, vehicle-mounted client with the information synchronization that receives to the information processing partly of oneself navigation module.
The real-time road function.Vehicle-mounted client is when carrying out the navigation way planning; To receive relevant regional real-time road network traffic information to server through this function, real time parsing information is upgraded local data base and is also read local traffic information; In conjunction with historical data; Driving custom, and real time data are cooked up best traffic route.
The on-line search function.The Data Update that obtains during from server end in conjunction with vehicle-mounted client, the user can carry out title retrieval, road path searching, curbside information, coding retrieval, historical information point to map through this function and search, and can navigate according to Search Results.
The friend information interactive function.The user of vehicle-mounted client can carry out information interchange with other online vehicle-mounted clients, and can the number of the account of other vehicle-mounted clients be added on the buddy list of vehicle-mounted client, is recorded in simultaneously in the subscriber information management database on the server, the convenient interchange.The transmitting-receiving of request of data is through transit server between the vehicle-mounted client, and the transmitting-receiving of Word message is then through the GSM mobile handset Network Transmission.
Good friend's navigation feature.The user uses vehicle-mounted customer end A to send the friend location request to server; After server receives request; Vehicle-mounted customer end B to vehicle-mounted customer end A is selected is sent position requests; After request was accepted by vehicle-mounted customer end B, target carriage was carried customer end B and is received the geographical location information of self and send this information from Navsat, and information sends on the vehicle-mounted customer end A from transit server.After vehicle-mounted customer end A receives this information; Utilize the navigation module of self to calculate the geographic position of vehicle-mounted customer end B and pass through the display module demonstration; The position that the user can select target carriage is carried customer end B is initiated the navigation from self to vehicle-mounted customer end B as the destination through the navigation module of vehicle-mounted customer end A.
Fleet's navigation feature.The user uses vehicle-mounted customer end A selected plural target good friend (vehicle-mounted customer end B, vehicle-mounted client C) in buddy list to send the request of navigator to server, and server receives and should send request to vehicle-mounted customer end B, vehicle-mounted client C in the request back.Vehicle-mounted customer end B, vehicle-mounted client C are the member of vehicle-mounted customer end A navigator troop after accepting request.The member of navigator troop shares the positional information of self mutually.In the navigator troop, vehicle-mounted customer end B, vehicle-mounted client C all can show the straight line line with the vehicle-mounted customer end A of leader from the car position, and initiate with the car navigation.The vehicle-mounted customer end A of leading a group can specify a place to initiate the destination navigation request; Request is issued on other team member's clients through transit server equally; The vehicle-mounted client that accepts request will utilize navigation module to initiate the navigation to this destination; Through this function, the several users position sharing of can forming a team on demand to carry out.Specifying a certain user by the promoter is the leader.Receiving the user who forms a team to invite can accept or refuse on demand, and the user of acceptance is the member of troop.In forming a team,, and initiate with the car navigation with the straight line line that can show per family from car position and leader.When forming a team, set the destination like the leader, relevant teammate all can accept/refuse this destination navigation.
One key admittance boat function.The user can directly call system's customer service through communication module through the special ptt button on the vehicle-mounted client; Can propose the requirement of information point search and path planning then to the contact staff, the contact staff will provide required information feedback for the user according to user's the requirement search through server data.Feed back to geography information on user's the vehicle-mounted client by customer service and can directly call the navigation module of client and initiate navigation, very convenient.
