Detailed description of the invention
It is more fully described the exemplary embodiment of the disclosure below with reference to accompanying drawings.Although accompanying drawing shows The exemplary embodiment of the disclosure, it being understood, however, that may be realized in various forms the disclosure and not Should be limited by embodiments set forth here.On the contrary, it is provided that these embodiments are able to more thoroughly Understand the disclosure, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Fig. 1 shows the schematic flow sheet of a kind of localization method, such as figure Shown in 1, in the normal mode, the method includes:
Step S110, opens base station information and obtains function and/or WiFi acquisition of information function.Specifically, In the case of opening base station information acquisition function, one can be obtained according to the mobile communications network accessed Base station information to multiple base stations；In the case of opening WiFi acquisition of information function, it is possible to obtain attached The information of nearly hotspot.
Step S120, it may be judged whether meet and get condition ready.
Step S130, when meet get condition ready time, it may be judged whether open GPS function.
Step S140, when being judged as being not turned on GPS function, according to the base station information currently got And/or WiFi information determines current location, and perform to get operation ready.
Illustrate the base station information according to currently getting and determine current location, i.e. the method for architecture: Measure the down-bound pilot frequency signal of different base station, obtain TOA (the Time of of different base station descending pilot frequency Arrival, due in) or TDOA (Time Difference of Arrival, the time of advent is poor), According to this measurement result the coordinate that combines base station, for example with triangle formula algorithm for estimating, it becomes possible to really Settled front position.
The WiFi information according to currently getting that illustrates determines current location, i.e. the side of WiFi location Method, the precondition of the method is: each hotspot has a globally unique MAC Address, And generally speaking hotspot will not move within a period of time；And, there is setting of WiFi function Standby can scan and collect the hotspot signal of surrounding in the case of opening WiFi, no matter this letter Whether number corresponding network is encrypted, is the most connected, and even signal intensity is not enough to display in wireless communication In number list, the MAC Address that focus broadcasts out can be got；Therefore these wireless heat is added up The positional information of point, it is possible to obtain comprising the data base of wireless hotspot location information, for example, it is possible to will This database purchase is in location server.When needs carry out WiFi location, obtain WiFi information, The WiFi information that these can indicate hotspot is sent to location server, and location server is accordingly Retrieve the positional information of each hotspot, further combined with the degree of strength of each signal, just may be used To determine current location.
Operation of getting ready in above-mentioned steps includes: record current location information is also reported to server.
Visible, the method shown in Fig. 1, select in multiple positioning modes, note can be effectively ensured Record current location information is also reported to server, i.e. gets the precision of operation ready.Specifically, power consumption is first opened Relatively low base station information obtains function and/or WiFi acquisition of information function, it may be judged whether meets and gets condition ready, If meeting and getting condition ready, then further determine whether to open GPS function, if it is determined that be not turned on GPS function, then base station information and/or WiFi information according to currently getting determine current location, and Operation is got in execution ready.This technical scheme decreases the power consumption of location while ensureing positioning precision, therefore Can economize on resources so that the application scenarios of this localization method is the most extensive, is especially suitable for wearable device Deng the smart machine strict to power consumption requirements.
In one embodiment of the invention, the method shown in Fig. 1 also includes: when being judged as opening GPS During function, open GPS function and also obtain GPS information, according to the base station information currently got and/or WiFi information and GPS information determine current location, and perform to get operation ready.
In the present embodiment, add GPS positioning function so that multiple positioning modes can optimum combination, More preferably positioning result is provided.Little, location affected by environment, GPS location rapidly, with WiFi location and It is the highest that architecture compares precision, and civilian GPS location can also reach 3 meters, and military GPS positions Even can reach 0.3 meter.Therefore can be according to the GPS information got to acquired base station information And/or WiFi information is corrected, obtain positional information more accurately.
In one embodiment of the invention, in the method shown in Fig. 1, during the condition of getting ready includes as follows Any one:
A. according to the base station information currently got and/or WiFi information, it is judged that current location is with last Between position when getting ready, whether displacement exceedes preset length value, is, determines to meet and gets condition ready.
It is to say, carry out new getting ready after displacement reaches preset value again.Such as under driving scene, car When speed is higher, this preset length value can arrange bigger, it is to avoid frequently carries out getting ready operation, wastes resource. Relatively low, under pedestrian scenarios, when i.e. translational speed is relatively low, preset length value can arrange less.
B. judge whether base station handover event according to the base station information currently got, be, determine full Foot gets condition ready.
According to above it will be appreciated that, the precision of architecture is relevant to the base station information got, and is obtaining Base station information the most time, it is the most accurate to position.And when base station switches, used by calculating Parameter also there occurs change, and it is critically important for carrying out when therefore switching in base station getting operation ready.
C. between position when current location and last time are got ready, displacement is not less than preset value, and base does not occurs yet Stand handover event time, it is judged that whether the distance last time got ready reaches the first preset time value, is then Determine to meet and get condition ready.
In this case, the object of location is not subjected to displacement or range of activity is the least (such as often In classroom, office or family), now can the most more new location information, enter Row gets operation ready.Wherein, when judging that the time once got ready in distance reaches the first preset time value, This preset time value is multiplied by after prescribed coefficient as the preset time value judged next time.Such as working day Time, the user of wearable device bends over one's desk working in office, and displacement does not changes and base station does not switch. Now carry out getting operation ready after 4 minutes at the first Preset Time, owing to the positional information updated is not sent out Changing, updates continually and simply expends electricity, therefore can carry out getting ready next time after 8 minutes Operation, by that analogy 8 minutes, carry out getting operation ready after 16 minutes, prescribed coefficient is 2 in this example.
D. according to the base station information currently got and/or WiFi information, it is judged that current location is with last Between position when getting ready, whether displacement exceedes preset length value；Base station information according to currently getting is sentenced Break and whether base station handover event occurs；If displacement surpasses between position when current location and last time are got ready Cross preset length value and base station switching time occurs, it is determined that meeting and get condition ready.
E. according to the base station information currently got and/or WiFi information, it is judged that current location is with last Between position when getting ready, whether displacement exceedes preset length value；The time that the judging distance last time is got ready is No reach the first preset time value；If displacement exceedes between position when current location and last time are got ready Preset length value and the distance last time got ready reach the first preset time value, it is determined that meet and beat Point condition.
F. judge whether base station handover event according to the base station information currently got；On judging distance Whether the time once got ready reaches the first preset time value；If it occur that base station handover event and distance The time that last time is got ready reaches the first preset time value, it is determined that meets and gets condition ready.
G. according to the base station information currently got and/or WiFi information, it is judged that current location is with last Between position when getting ready, whether displacement exceedes preset length value；Base station information according to currently getting is sentenced Break and whether base station handover event occurs；Whether the time that the judging distance last time is got ready reaches first when presetting Between be worth；If between position when current location and last time are got ready, displacement exceedes preset length value, and sends out Give birth to base station handover event, and the distance last time got ready reached the first preset time value, it is determined that Meet and get condition ready.
Condition d, e, f, g are to condition a, the permutation and combination of b, c.In actual scene, Ke Yigen Select be more suitable for get condition ready according to demand.
In one embodiment of the invention, in the method shown in Fig. 1, it may be judged whether open GPS function Including: judge the displacement between position when current location and last time are got ready the most within the specific limits； Record when the most then getting ready according to the last time judges whether have GPS information when the last time is got ready；If having GPS information, then open GPS function, otherwise, be not turned on GPS function.
Use precision higher GPS location can increase power consumption, it is therefore desirable to set up for it and reasonably implement bar Part.It is corrected in view of using GPS location mainly architecture and/or WiFi to be positioned, and Open this function to first have to search for gps satellite, start relatively slow, therefore first determine whether current location and upper The direct displacement in the secondary position got ready is the most excessive.
In a preferred embodiment, it is judged that method is: judge that the current base station connected and adjacent base station are with upper Whether the base station connected when once getting ready and the coincidence factor of adjacent base station reach first threshold, the most true The displacement between position when settled front position and last time are got ready within the specific limits, otherwise determines current The displacement between position when position and last time are got ready is the most within the specific limits；Or, it is judged that currently sweep Whether the coincidence factor of each Wi-Fi hotspot that each Wi-Fi hotspot retouched scans when getting ready with the last time reaches Second Threshold, if, it is determined that the displacement between position when current location and last time are got ready is necessarily In the range of, otherwise determine that the displacement between position when current location and last time are got ready is not in certain limit In.
As a example by architecture, if in the base station information got, the current base station connected and adjacent base Stand and reach with the last coincidence factor getting base station and the adjacent base station being connected in the base station information got ready 30%, then judge displacement within the specific limits.By WiFi position as a example by, if Current Scan arrive each The coincidence factor of each Wi-Fi hotspot that Wi-Fi hotspot scans when getting ready with the last time has reached 50%, then sentence Location is moved within the specific limits.
If it is determined that displacement is without departing from scope, then determine whether when the last time is got ready, whether have GPS to believe Breath, if there is no GPS information, may explanation upper once get ready time cannot get GPS information (example As searched less than satellite-signal), now open GPS function and be likely to obtain less than GPS information, only meeting Waste resource.The most in this case, only upper once get ready time have a GPS information time just open GPS function.
If it is determined that between position when displacement is got ready without departing from scope, i.e. current location and last time Displacement the most within the specific limits, then opens GPS function.In other words, send out when the position of the object of location When having given birth to bigger change, it is necessary to determine its positional information more accurately, therefore use the higher GPS of precision Architecture and/or WiFi are positioned and calibrate by location mode.
