Specific embodiment
A kind of air navigation aid based on mobile terminal disclosed in this invention, divides according to the information that each mobile terminal is reported
Do not calculate the circuit that each mobile terminal reaches the destination, and this circuit is transmitted separately to each mobile terminal to realize for not
With the navigation of mobile terminal, smoothly reach the destination offer configured information for all users.
In the present embodiment, mobile terminal carries position location services function, including satellite fix, architecture and Wi-Fi
Positioning.Mobile terminal can pass through the means of communication such as 2G, 3G, 4G or Wi-Fi, is communicated with server.Described mobile terminal
Server adopts CS model, installs the interactive system software client of an integrated map function in advance on the mobile terminal device
End, then installs one on back-end server and has the system processing client-side information.
As shown in figure 1, being included based on the air navigation aid of mobile terminal：
Step S10：Pass through server between current mobile terminal to be connected with the foundation of other mobile terminals.
In the present embodiment, each mobile terminal needs to server application identity ID before use, and described identity ID has
Uniqueness.Current mobile terminal, can be entered by server to other mobile terminal launch position interaction request according to identity ID
And set up communication connection.
Specifically, current mobile terminal will need identity ID of other mobile terminals participating in the interaction of this position, and
Position interaction request order is sent to server.After server receives interaction request order, inquire that other are mobile eventually according to identity ID
Whether end accepts this position interaction request.When other mobile terminals accept request after, server will for request position interaction with
The mobile terminal of requested position interaction is random to generate a key, sends to all mobile terminals agreeing to position interaction.Each shifting
After key described in dynamic terminal authentication, set up and communicate to connect successfully.
When the mobile terminal quantity of participant position interaction is more, interacted in group's mode.Such as first is mobile whole
A customer group is set up by server in end, and group members include A1、A2…An, the arbitrary mobile terminal in this customer group all can send out
Play position interaction request, thus setting up communication connection with other group members.
Step S20：Server is according to the circuit of each mobile terminal reported position calculation mobile terminal to destination.
After each mobile terminal sets up position interaction, represent that described each mobile terminal can pass through server share position each other
Put.By selecting navigation pattern, servers' layout can be made to go out the circuit of each mobile terminal.When each mobile terminal receives key
Afterwards, selected the navigation pattern of server by the mobile terminal initiating the interaction of request position, pattern includes searching modes, follow the mode
With converge pattern, server carries out layout of roads for different mode, illustrates individually below：
First, searching modes.
First, the mobile terminal initiating the interaction of request position selects to find object and is found object.In this pattern, sought
Look for a partner in marriage position be destination it is generally the case that by find object position constant.
Secondly, time interval is sent to server after encrypting respective positional information key according to the rules.Mobile terminal
The time interval that described positional information reports can be adjusted according to the translational speed of itself, for example, hold the use of mobile terminal
During the transfixion of family, adjustment time is spaced apart 1 minute；Hold mobile terminal user's walking when, adjustment time is spaced apart 10～
15 seconds；Hold the user of mobile terminal by bike when, adjustment time interval can be 5～10 seconds；Hold the user of mobile terminal
Self-driving or when taking advantage of public transport, adjustment time interval can be 1～5 second, thus can save mobile terminal electricity, and reduce server
Data processing amount.
Server judges the move mode of each mobile terminal according to received positional information, and described move mode includes
Walking, by bike, self-driving or public transport etc..Server for the basis for estimation of the move mode of mobile terminal is：According to mobile
The displacement that terminal produces at timed intervals judges its translational speed.For avoiding error, can be using the mean value calculation of multiple measurement.
Finally, server will be found object position and will be set to destination, according to general routing algorithm, calculate
Article one, point-to-point transmission is the shortest, and suitably finds the walking path of move mode that object is adopted, by walking path sender to seeking
Look for a partner in marriage held mobile terminal.Server, after receiving positional information each time, updates the geographical position of two people on map
Put, and feed back to mobile terminal.
2nd, follow the mode.
First, the mobile terminal initiating the interaction of request position selects to follow object and is followed object.For example, select itself
For being followed object, other mobile terminals are selected to be to follow object.Now destination is the position being followed object place, is sought
Position of looking for a partner in marriage is mobile.
Secondly, it is followed mobile terminal that object holds according to being followed the translational speed of object by positional information key
Send to server after encryption.
Then, server is to follow the mobile terminal that object holds and set up to follow list of locations, by received by with
Store one by one with the positional information that the mobile terminal that object is held sends and follow in list of locations to described, and send described position
List is to following object.
Follow object will send after the encryption of the positional information key of position to server, when follow object through with
During with position in list of locations, follow the held mobile terminal of object and this position is deleted from following list of locations, to update
Described follow list of locations.
Further, at interval of 1～5 second, follow object held mobile terminal geographical position is sent to and be followed object
The mobile terminal held, being followed object can regulate the speed according to the position of follower is adaptive.
When server judges to follow object by being followed the walking of object walked route, navigation circuit need not be calculated, directly
The position one by one being followed object is coupled together and can form a complete path, eliminate the one-tenth calculating path
This, improve the performance of navigation.
But, when follow object not according in described list of locations circuit walking when, then server according to be followed right
The position of elephant, the optimal path that object is followed in calculating is followed object so as to pull up within to the short time.Described optimal path
Calculate according to traffic congestion situation and the relative distance between the two, concrete calculating process repeats no more.
3rd, converge pattern.
Converge in pattern, destination need to calculate according to the position of each mobile terminal, this destination satisfaction is held each mobile whole
The user at end met within the shortest time.
First, server judges the move mode of each mobile terminal according to received positional information.Determination methods with
Searching modes are identical, repeat no more.
Secondly, server is according to the move mode of each mobile terminal judged, setting difference translational speed weight.Example
As, according to trip speed different, by walking speed be set to 5 kilometers/when, by bike speed be 15 kilometers/when, take advantage of public affairs
Hand over vehicle speed be 30 kilometers/when, self-driving speed be 40 kilometers/when, therefore speed weight E of walkingWalking=1；Speed by bike
Degree weight EBicycle=3；Speed weight E riding in a busPublic transport=6；Speed weight E of self-drivingSelf-driving=8.
Then, server, according to above-mentioned weight, again delimited coordinate system, is calculated each mobile terminal and again delimit described
Coordinate system under position.
Calculating formula is：In above-mentioned two formulas, (x0,y0) it is with reference to mobile
The changing coordinates of terminal, in the present embodiment, select translational speed mobile terminal the slowest as with reference to mobile terminal；If existing many
During the mobile terminal of individual employing walking movement, then using the focus point of multiple mobile terminal locations of multiple employing walking movements as
Changing coordinates with reference to mobile terminal；(xn,yn) be each mobile terminal changing coordinates, n be mobile terminal quantity；(x'n,
y′n) it is coordinate (xn,yn) position under the described coordinate system again delimited；E is weight ratio, E=En/E0, EnFor each movement eventually
The weighted value at end, E0It is the weighted value with reference to mobile terminal.
Finally, the meansigma methodss again delimiting each position under coordinate system are calculated, that is, position of centre of gravity is as destination, this destination
The user that satisfaction holds each mobile terminal meets within a short period of time, and reduces the impact of vehicles translational speed.Calculating formula
For： (x, y) being calculated is the coordinate of destination.
