Based on the embodiment in the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, broadly falls into the scope of protection of the invention.
Embodiment of the method one:
Seeing Fig. 4, this figure is the flow chart of a kind of air navigation aid embodiment one that the present invention provides.
The air navigation aid embodiment that the present invention provides comprises the steps:
Step S101: obtain user current location.
In actual applications, the current location information of user, such as profit can be obtained in several ways
With GPS (Global Positioning System, global positioning system), wireless mobile communication base station etc.
The mobile terminal that user is carried by mode positions, thus obtains the position that user is current.
The type of the occurrence in order to represent described current location is not specifically limited by the present invention, permissible
It is through, latitude coordinate, it is also possible to be the plane coordinates etc. by obtaining after, latitude coordinate is changed.
Step S102: be retrieved as user planning from default starting point to the route of default terminal.
In the present embodiment, described route at least includes stretch footpath, every section of path includes at least
One key position point.For example, it is assumed that default starting point is Fang Heng International Center, Beijing, preset eventually
Point is Yi Zhuang Qiao Nan bus station, then from a wherein road of described default starting point to described default terminal
Line information is: from permanent International Center, side, walking 273 meters to Fu Tong East Street Bei Kou (bus station),
Take 563 tunnels (direction, the Zuo Jia village), get off at subway San Yuan Flyover station (bus station), walking 54 meters,
Get on the bus at the San Yuan Flyover station of No. 10 subway/light rail line internal ring (bright Ma Qiao direction), get off at Song Jiazhuan station, so
Rear walking 14 meters is got on the bus at the Song Jiazhuan station in subway Yi Zhuang line (secondary canal direction), gets off at bridge station, Yi Zhuang,
Walking 204 meters arrives Yi Zhuang Qiao Nan (bus station).
In the present embodiment, described path is according to modal spli, and described trip mode includes
Walking or ride public transportation means.The most above-mentioned route can be divided into 7 paths, they respectively:
Fu Tong East Street Bei Kou (bus station) (path 1), big from Fu Tong east is walked to from permanent International Center, side
Street Bei Kou (bus station) takes 563 roads to subway San Yuan Flyover station (bus station) (path 2), from ground
No. 10 subway/light rail line San Yuan Flyover station (path 3) is walked to, from San Yuan Flyover in ferrum San Yuan Flyover station (bus station)
No. 10 subway/light rail line is taken to station, the Song Jia village (path 4), walking of standing from the Song Jiazhuan of No. 10 subway/light rail line in station
To station, the Xian Songjia village, subway Yi Zhuang (path 5), also take subway from station, the Xian Songjia village, subway Yi Zhuang
Village line to bridge station, Yi Zhuang (path 6), walk to Yi Zhuang Qiao Nan from the bridge station, Yi Zhuang of subway Yi Zhuang line (public
Hand over station) (path 7).
It should be noted that in actual applications, it is the most detailed that described route is likely not to have above-mentioned example,
Sometimes due to the distance in walking path between subway transfer or Public Transport Transfer is the shortest and be ignored, but
It is a subway or a road public transport now should be considered as a paths, and should will not take continuously
Article two, (road) or a plurality of (road) subway (public transport) regards a paths as.For example, it is assumed that certain
Route is: takes pubic transport from southern station, Jianguomen and arrives northern station, Dongzhimen 44, changes to 75 tunnels straight from east
Door northern station arrives Terrace west gate (bus station), then in this section of route, takes pubic transport 44 outward from building
Southern station, the gateway of a country is a paths to northern station, Dongzhimen, and 75 tunnels of taking pubic transport arrive Terrace from northern station, Dongzhimen
West gate (bus station) is another paths.
Continue by aforementioned as a example by the route of permanent International Center to Yi Zhuang Qiao Nan bus station of side, at these 7 sections
In path, each paths all includes at least one key position point.The present invention is to how to choose every
Key position point corresponding in path is not specifically limited, and those skilled in the art can answer according to reality
Use demand sets itself.In the present embodiment, terminal or the starting point conduct in each path can both be chosen
Key position point, it is also possible to choose the intermediate point between the Origin And Destination in described path as closing key mapping
Put a little.Described intermediate point can be to take pubic transport path and take each website of subway route, it is also possible to
It is at the direction changes such as the transfer of walking path is curved, turn around or other points preset.
Step S103: from user without key position point, obtain distance users current location
A near key position point is as source location.
In the present embodiment, the starting point in described source location each section of path in can being described route or end
Point, it is also possible to be the intermediate point between the beginning and end in described path.When the route planned for user determines
After Hao, in this route of user's process, the sequencing of each key position point also determines that.Whenever with
Family through a key position point, can so that this key position point is marked, the mode such as deletion makes
Process key position point and without key position point be distinguished, in order to from user without
In key position point, obtain a nearest key position point of distance users current location as target location
Point.
Step S104: when user current location is when near described source location, report and described target
The navigation hint information that location point is relevant.
Described report can by text importing, voice message or both combination by the way of and other modes enter
OK, the present invention is not specifically limited.
In actual applications, described navigation hint information should be with the type of described source location and trip side
Formula adapts.When described source location is the terminal that user is currently located path, or next section of path rise
Point, and user be currently located path for ride public transportation means (such as public transport or subway etc.) time, described navigation
Information can include remind user will arrive at a station, transfer stop, to transfer stop walking distance, will arrive
Reach terminal etc.；When user be currently located path be walking time, described navigation information can include reminding on user
Car, current location and the distance etc. of website of getting on the bus.When described source location is intermediate point, and user is current
When the path at place is for riding public transportation means, described navigation hint information can include arriving certain station and
This path termination also has how many station, about also needs to how long arrive this path termination etc.；When user is current
When the path at place is walking, described navigation hint information can include distance turning point also need to how long away from
From, to where to turning etc..
Either prior art one or prior art two, all intuitively shown by text importing and map
Mode gives the whole piece route into user's planning, and user needs to combine self position and planned
Route mates voluntarily, to obtain ensuing trip information.When road is the remotest, user is easy to forget
Note route information, it is thus possible to need the repetitious coupling carrying out current location and route, the most inconvenient.
And the present embodiment from user without key position point, obtain distance users current location nearest one
Individual key position point, as source location, when user current location is when near described source location, is broadcast
Reporting the navigation hint information relevant to described source location, therefore user just can facilitate without coupling voluntarily
Obtain next step trip information efficiently, improve user satisfaction.
Embodiment of the method two
Seeing Fig. 5, this figure is the flow chart of a kind of air navigation aid embodiment two that the present invention provides.
The air navigation aid embodiment that the present invention provides comprises the steps:
Step S201: obtain user current location.
Step S202: be retrieved as user planning from default starting point to the route of default terminal.
At least including stretch footpath in described route, every section of path is including at least a key position point.
Step S203: from user without key position point, obtain distance users current location
A near key position point is as source location.
Step S204: judge user whether near described source location, if it is, perform step S205.
Step S205: judge that whether described source location is the terminal that user is currently located path, as
Fruit is, then perform step S206；If it is not, then perform step S208.
Although it should be noted that to first carry out in the present embodiment and judging that whether user is near described target
The step of location point, rear performs to judge that whether described source location is the end that user is currently located path
The step of point, but the program is not intended that limitation of the invention, in actual applications, it is also possible to
First carry out step S205, rear execution step S204.
Step S206: judge described user current location to described source location distance whether less than or
Equal to the first threshold preset, if it is, perform step S207.
Step S207: report the navigation hint information relevant to described source location, described navigation hint
Information includes the navigation information in next section of path, and flow process terminates.
In the present embodiment, when described source location is the terminal that user is currently located path, and user works as
Front position to described source location distance less than or equal to preset first threshold (such as 1km) time,
Report the navigation hint information including next section of path navigation information.It is to say, when user is near working as
The terminal in path, front place, and with the distance of described terminal less than or equal to described first threshold time, prompting is used
Path, next section of family this how to go on a journey.
For example, with reference to Fig. 6, when user takes 563 roads to ground from Fu Tong East Street Bei Kou (bus station)

Line internal ring (path 3 in embodiment of the method one)；Transfer No. 10 subway/light rail line internal ring, from (bright Ma Qiao
Direction) San Yuan Flyover station get on the bus (not shown in Fig. 6).
Except using text importing and voice mode to remind user to arrive at a station, in actual applications, also
Can remind to use vibrations, light flash, the mode such as pipe.
Step S208: obtain described source location and user be currently located path terminal and between
Each key position point.
Step S209: report and described and source location, be currently located path terminal and between
The navigation hint information that each key position point is relevant, flow process terminates.
In the present embodiment, when described source location is not the terminal that user is currently located path, obtain
Take described source location and user be currently located path terminal and between each key position point, and
Report with described and source location, the terminal being currently located path and between each key position point phase
The navigation hint information closed.It is to say, when described source location is the starting point that user is currently located path,
Or during intermediate point between Origin And Destination, report is not only the information about source location, and
Also include about each intermediate point between user place path termination and described source location and terminal
Information.
For example, with reference to Fig. 7, when user takes No. 10 subway/light rail line to station, the Song Jia village (method from San Yuan Flyover station
Path 4 in embodiment one), and when source location is starting point San Yuan Flyover, obtains and include described ternary
Bridge station and described station, the Song Jia village and between all websites, the information now reported may include that seat
No. 10 subway/light rail line internal ring, gets off at Song Jiazhuan；Station, the distance Song Jia village also has 13 stations, about 27 minutes；
The next stop is bright Ma Qiaozhan.
Described source location is classified by the present embodiment, be user be currently located path terminal and
Non-user is currently located the terminal in path, with the corresponding navigation information reporting correspondence to user, from above-mentioned
If about navigation information citing it can be seen that described navigation information ratio in greater detail, user not only may be used
To understand the position oneself being presently at any time, it is also possible to know what next step should do, what time
Time is done, and user need not oneself analyze and judges just to have the trip planning of oneself at fingertips, pole
Improve greatly Consumer's Experience.
Embodiment of the method three
Differring primarily in that of the present embodiment and described embodiment of the method one and described embodiment of the method two: this reality
Execute example to provide and a kind of determine that user current location is whether in the method near source location.

To a some B, then taking bus point of arrival C at a B, therefore, path AB and path BC there occurs
It is overlapping that (in order to see, Fig. 9 is by shown separately for these two sections of paths, and these two sections of paths actual are overlapping
).User is currently located at O point, and this first mapping position point mated on the AB of path is an O1,
On the BC of path coupling the first mapping position point for some an O2 (in order to see, Fig. 9 midpoint O, O1
Shown separately with O2, actual these three point is to overlap).If user is current towards a B walking,
User without path be path AB and path OC, this time point B is the target position that distance users is nearest
Put a little, then determine that user is to first pass through path AB according to predetermined paths, after through path BC, therefore
Choose on the path AB first passed through some O1 as the first mapping position point mated with current time period,
And utilize described first mapping position point O1 to judge that user is the most near source location B；If using
The most just taking pubic transport point of distance B at family, owing to now path AB necessarily has become as the path of process,
Therefore directly using the some O2 on the BC of path as the first mapping position point mated with current time period.
