Description
Technical field
The present invention relates to field of locating technology more particularly to a kind of location frequency optimization methods, apparatus and system.
Background technique
Positioning device has much on the market at present, including the equipment such as locator, location watch, positioning bracelet.It is set this kind of
In standby, because being limited by product form and product will either pass through according to certain frequency acquisition location information
Flush bit information is carried out in GPS, WiFi or base station, very severe to the test of product cruising ability, that is to say, that different determines
Position strategy, determines the continuation of the journey duration of battery.
This kind of product, and there are two types of the relevant common features of positioning:
One is obtain real-time position information.
Another kind is that a specified region will have corresponding prompting when equipment passes in and out the region, and this function is common
In the product mix of " positioning device+APP ", such as the fence function at 360 ends children bodyguard APP.
Above two function has in common that, will constantly obtain the current location of equipment according to certain frequency.
Widespread practice is the time interval of stationary positioned, such as the location information of refreshing in 30 seconds or 2 minutes.
We take children's location watch citing on the market, any location frequency of power saving, which such as be arranged 5 minutes, positions one
It is secondary, it is exactly that child does not go out at the edge in specified region in the case where extreme, has refreshed position at this time, be judged as child still
It is so safe, then refreshing is exactly the thing after 5 minutes next time, if child specifies outside region along straight line toward this
It walks, waits by the time, child is likely to leave the good remote place in safety zone.This location frequency, cannot get safely
It ensures.
The same children's location watch citing taken on the market, can ensure that the location frequency of position safety is such as arranged 30 constantly
Second refresh primary, extreme situation is exactly that child plays in situ, then refreshings substantially each time be all waste, and
It, will be out of power by 2 hour wrist-watches of this frequency and with the estimation of one piece 600 milliamperes of watch cell.After so out of power, child
Safety cannot equally ensure.

Continuation of the journey problem.Using gravity sensor optimum position strategy, especially to " specify a region, when equipment passes in and out the region,
Having corresponding prompting " this function is largely effective, above-mentioned similar device is reduced because causing to continue a journey the problem of location frequency
The probability of scarce capacity, while parent can be allowed to know whether child is in safety zone at the first time.
In order to preferably be realized using device M " a region A is specified, when device M passes in and out the specified region A, to be had
This function of corresponding prompting ", the localization method strategy of the positioning device are as follows:
When A0, open function, positioning is primary, using newest current location P judgment means M in specified region A still
Outside；
A1, using newest current location P, calculate shortest distance D of the device M from the edge specified region A；
A2, step counting effect is done using gravity sensor, step counting value is denoted as S, and when obtaining latest position each time, S is reset；
The universal way of step counting is that the signal of gravity sensor reaches a minor peaks, counts a step, i.e. S adds 1, is not described further in detail here, such
Ready-made utilization has become ubiquitous；
A3, assume device M holder average paces length be d, then device M to leave specified region A condition it
One, S >=shortest distance D/ is averaged paces length d, i.e., at least to walk D/d step and be possible to leave region A；
A4, because what d took is average value, it is above-mentioned whether to leave specified region A with possibility, at this point, fixed again
Position repeats A0-A4, until determining device M has gone out specified region A to energy completely.
Likewise, if device M outside specified region A, can detect whether to enter specified by the above method
Region A.
As it can be seen that location frequency optimization is realized since the present invention is the carry out flush bit purposive according to estimation result,
Technical solutions according to the invention can solve the problems, such as the continuation of the journey of product while guaranteeing the validity of positioning function.
Calculation about shortest distance D is described below:
For polygon, current location P point can be calculated to the vertical range on each side, be denoted as d1, d2, d3 ...
Dn, n represent the quantity on the side of polygon.So shortest distance D=min { d1, d2, d3 ... dn }.
For circles, center of circle O and current location P point are crossed, straight line is done and intersects at round side, obtain two intersection points: M,
N remembers P point to M, and the distance of N is respectively MP, NP.So shortest distance D=min { MP, NP }.
