Description
Technical field
The invention belongs to mobile service scene fields, and in particular to a kind of dynamic based on polygon fence and running fix
Prediction technique and device.
Background technique
With the development of smart phone, mobile positioning technique has been applied to people's lives work more and more.
In order to specific geographic area realize to mobile phone difference manage, need to connect on map several coordinate points establish it is polygon
The polygon fence of shape executes corresponding management and control measures when mobile phone enters, leaves polygon fence boundary.
Due to being only capable of obtaining current location when the positioning of each mobile phone, and frequent progress running fix will lead to mobile phone power consumption and add
Fastly, therefore predict how long mobile phone reaches fence boundary afterwards and be particularly important.In order to save electricity and prediction across fence when
Between, the dynamic prediction method based on polygon fence and running fix that we have proposed a kind of.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention proposes that a kind of dynamic based on polygon fence and running fix is pre-
Survey method, effective solution problems.
The present invention to achieve the above object, is implemented with the following technical solutions:
According to an aspect of the invention, there is provided a kind of dynamic prediction side based on polygon fence and running fix
Method, comprising the following steps:
Using history positioning result, fitting obtains the time changing curve of mobile phone travelling speed；
According to current anchor point, minimum range of the mobile phone apart from polygon fence is calculated；
According to the time changing curve and minimum range, predict that mobile phone reaches the time of polygon fence boundary.
Preferably, described according to the time changing curve and minimum range, predict that mobile phone reaches polygon fence boundary
Time, comprising:
The mobile phone speed mobile to polygon fence boundary is predicted according to the time changing curve.
Preferably, the method further includes:
The time of polygon fence boundary is reached according to the mobile phone of the prediction, adjusts mobile phone running fix time interval.
Preferably, when mobile phone is when moving slowly at and/or far from fence boundary, dynamic reduces mobile phone location frequency.
Preferably, when fast moving in mobile phone and/or close to fence boundary, dynamic accelerates mobile phone location frequency.
According to another aspect of the present invention, a kind of dynamic prediction based on polygon fence and running fix is additionally provided
Device, including with lower unit:
Fitting unit, using history positioning result, fitting obtains the time changing curve of mobile phone travelling speed；
Metrics calculation unit calculates minimum range of the mobile phone apart from polygon fence according to current anchor point；
Time prediction unit predicts that mobile phone reaches polygon fence side according to the time changing curve and minimum range
The time on boundary.
Compared with prior art, the present invention have the following advantages that and the utility model has the advantages that
It is moved slowly in mobile phone and when far from fence boundary, location frequency can dynamically be reduced by the prediction of this method, saved
Save electricity.It is fast moved in mobile phone or when close to fence boundary, future trend can be predicted by this method in time, accelerate positioning frequency
Rate, the sensitivity of enhancing mobile phone control.
Detailed description of the invention
Fig. 1 is flow chart of the method for the present invention.
Fig. 2 is the device of the invention structure chart.
Specific embodiment
The present invention is described in further detail below with reference to embodiment, embodiments of the present invention are not limited thereto.
Prediction technique of the invention calculates the most low coverage to all boundaries of polygon fence according to the coordinate points of running fix
From, the data for taking n times to position recently, and fit velocity variations function.It can be accomplished by the function fitted:
1, the prediction mobile phone speed mobile to polygon fence boundary；
2, prediction mobile phone reaches the time of polygon fence boundary；
3, the time according to the arrival fence boundary of prediction, mobile phone running fix time interval is adjusted, electricity is advantageously reduced
Amount consumption.
Original location method is only capable of judging user whether in fence by the coordinate got, and equipment is fixed
Position time interval be it is fixed, electricity consumption of equipment is serious.
By this prediction technique, using history positioning result, fitting obtains the time changing curve of mobile phone travelling speed, then
According to current anchor point, the minimum range apart from polygon fence is calculated, thus predict that mobile phone crosses over the time used in fence,
When moving slowly at and far from fence boundary, location frequency can dynamically be reduced by the prediction of this method, save electricity.In mobile phone
It fast moves or when close to fence boundary, future trend can be predicted by this method in time, accelerate location frequency, enhance mobile phone pipe
The sensitivity of control.
Embodiment 1
As shown in Figure 1, mobile phone starts to position first.After mobile phone positions successfully, calculate mobile phone to polygon fence away from
From, thereby executing mobile phone fence inside/outside control strategy.
Then, the position and speed of nearest n times anchor point is obtained, to fit the speed change curves of mobile phone.
Finally, the time of fence is crossed over to the minimum range prediction of fence according to speed change curves and mobile phone, to count
Calculate the time positioned next time.When predict across fence time very in short-term, so that it may by increasing positioning to mobile phone
Frequency, the sensitivity of enhancing mobile phone control.And when predict the time across fence it is longer when, so that it may by reducing to mobile phone
Location frequency, to reduce mobile phone power consumption amount.
Embodiment 2
As shown in Fig. 2, the present invention also provides a kind of dynamic prediction device based on polygon fence and running fix, packet
It includes with lower unit:
Fitting unit 11, using history positioning result, fitting obtains the time changing curve of mobile phone travelling speed；
Metrics calculation unit 12 calculates minimum range of the mobile phone apart from polygon fence according to current anchor point；
Time prediction unit 13 predicts that mobile phone reaches polygon fence according to the time changing curve and minimum range
The time on boundary.
