Embodiment
Set forth a lot of detail in the following description so that fully understand the present invention.But the present invention can be much different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention, therefore the present invention is by the restriction of following public concrete enforcement.
Secondly, the present invention utilizes schematic diagram to be described in detail, and when describing the embodiment of the present invention in detail, for ease of illustrating, described schematic diagram is example, and it should not limit the scope of protection of the invention at this.
The invention provides a kind of air navigation aid, show the schematic flow sheet of air navigation aid one embodiment of the present invention with reference to figure 1.Described air navigation aid roughly comprises the following steps:
S1, obtains the route planning information of user;
S2, based on described route planning information acquisition approach layout data;
S3, in conjunction with Route Planning Data and map datum, provides navigation to user.
Below each step is described in detail:
Perform step S1, obtain the route planning information of user, route planning information at least comprises start point information, destination information herein, with according to start point information and destination information, to obtain the path from starting point to destination.Such as, starting point is Wang Wang mansion, and destination is People's Square.
In addition, described route planning information also comprises other information meeting user's request, whether the range information in path, the traffic information in path, path such as, to have on the information of refuelling station, path whether information having good friend etc.When navigating, user can arrange all kinds of route planning information according to the actual requirements.
In practical operation, user can pass through input media navigation Operation system setting route planning information, and make navigational system obtain the route planning information of user, particularly, navigational system guides user to complete the setting of route planning information usually.
Such as, user clicks the button of navigation Service on touch-screen, touch-screen can show the selectionbar of " starting point ", " destination " afterwards, after the information of user's input " starting point ", " destination ", touch-screen can continue to show the route planning information of such as " path that chosen distance is the shortest ", " selecting the path that road conditions are best ", " selection has the path of refuelling station " etc.Setting like this by guiding user to complete route planning information, thus obtain the path planning demand of user.
Perform step S2, obtain the Route Planning Data corresponding with it based on described route planning information, Route Planning Data is the path meeting route planning information herein.
Route Planning Data is meant to corresponding with described route planning information herein, Route Planning Data need be identical with the starting point in route planning information or one or two in destination, or identical to the part in the path of destination with starting point in route planning information.Such as, route planning information is the path the shortest to the distance of destination B from starting point A, correspondingly, route planning information be from starting point A along a road direction north, to b road right-hand rotation craspedodrome 500 meters arrive destination B.
Route Planning Data can come from the Route Planning Data that other car machines are uploaded herein, such as, other car machines drive to destination B from starting point A 3 kinds of Route Planning Datas, described 3 kinds of Route Planning Datas are all stored in the server of navigational system, when the route planning information of user is from starting point A to the path that the distance of destination B is the shortest, server is according to described route planning information, by comparing, from 3, obtain the shortest Route Planning Data of distance in Route Planning Data, be supplied to user.
Particularly, in present embodiment, the Route Planning Data that other car machines described are uploaded comprises other car machines and drives to destination from starting point and complete actual travel process and the Route Planning Data produced.
In other embodiments, the Route Planning Data that other car machines described are uploaded can also comprise other car machine users provides Route Planning Data from starting point to destination based on driving experience.The Route Planning Data that different car machine is uploaded is as a kind of resource shared, air navigation aid of the present invention based on the Route Planning Data of other car machines, can provide path planning service directly to user, navigates to user, avoid repetitive operation, increase work efficiency.
In addition, in order to more fully provide path planning, when other car machines upload Route Planning Data to server, described Route Planning Data comprises temporal information, temporal information described herein is the time that described Route Planning Data is formed, such as, other car machines drive to from starting point the time that destination completes actual travel process, and the Route Planning Data comprising temporal information can provide dynamic navigation information to user.
Such as: the first car machine provides the first Route Planning Data driving to destination B from starting point A along path c to server in morning peak, second car machine provides the second Route Planning Data driving to destination B from starting point A along path d to server in the morning peak period, although show paths in the first Route Planning Data, the distance of c is shorter, but the road conditions that the second Route Planning Data shows path d in the second Route Planning Data are better, the time therefore used is shorter.Therefore user is when the morning peak period, Route Planning Data as good in needs road conditions, and based on the Route Planning Data that the first car machine and the second car machine are uploaded, air navigation aid of the present invention can be chosen the second layout data and feed back to user.
In practical application, as do not stored the data schema data meeting user's request that other car machines are uploaded in server, therefore, described Route Planning Data can also come from the Route Planning Data that server provides, server is based on map datum and calculate acquisition approach layout data, such as, when the route planning information of user is from starting point A to the path that the distance of destination B is the shortest, server is based on map datum, measure the distance in the different path from A to destination B, by comparing, never with selected distance in path the shortest feed back to user.
Perform step S3, in conjunction with Route Planning Data and map datum, provide navigation to user.After server chooses the Route Planning Data meeting user's request, described Route Planning Data is transferred to the local car machine of user, described Route Planning Data combines with the map datum of local car machine, and navigation information is presented to user.
Described map datum comprises the position and annexation etc. of the title of subject matter, road name, different road.
Such as, when the route planning information of user is from starting point A to the path that the distance of destination B is the shortest, the display screen of navigational system demonstrates the partial enlargement map of starting point A to destination B, and the path of bee-line in starting point A to destination B is indicated with blue lines, be furnished with explanatory note from starting point A to the road name of destination B process and operating range in map side simultaneously.
