In traditional position location techniques, when terminal positions, normally open locating module with fixing location frequency and position.Terminal positioning is the situation in order to know user, needs to ensure certain positioning precision.Because terminal user may be in different active states, do not need picture to locate so frequently in motion state (such as in running) time when the place stayed for a long time (such as classroom), the location frequency that thus conventional art is fixed also exists the higher shortcoming of power consumption.
Below describe and a kind ofly at least can solve power consumption higher terminal positioning frequency adjustment method, system.A kind of positioning interval control method, system are also described simultaneously.
Fig. 1 is the terminal positioning frequency adjustment method schematic flow sheet of an embodiment.A kind of terminal positioning frequency adjustment method, comprises the steps:
Step S110: implement location according to known location frequency.Known location frequency can be the location frequency confirmed, such as, when this method has just started to start, can be default location frequency; Such as after this method starts, it can be the upper location frequency once regulating bout to confirm.
Step S120: the sensed data reading acceleration transducer.When sensed data meets pre-conditioned, enter step S130.Can be monitored and read the sensed data of acceleration transducer by audiomonitor, namely the sensed data of acceleration transducer is read in timing, to monitor the sensed data change of acceleration transducer.
Acceleration transducer can be 3-axis acceleration sensor, and the sensed data of acceleration transducer can comprise the acceleration information of three axis, such as the acceleration information of X-axis, Y-axis and Z axis three axis.The sensed data of acceleration transducer may be not merely the sensed data in a certain moment, and can be include the sensed data in a certain duration.
Pre-conditionedly can comprise the sight configuration data being pre-stored in local storage medium, sight configuration data is for determining the movement scenarios of terminal.Sight configuration data can comprise the acceleration information of three axis pre-set, the acceleration information of X-axis, Y-axis and Z axis three axis such as preset.The sensed data sensed when acceleration transducer meets default sight configuration data (can be such as be in a scope), is namely judged as that sensed data meets pre-conditioned.
Sight configuration data for determining the movement scenarios of terminal, such as determine terminal user static, walking, run, jump movement scenarios.Comprise the acceleration information of three axis pre-set for sight configuration data, such as sight configuration data comprises the acceleration information of default X-axis, Y-axis and Z axis three axis.Typically, user is when walking, running, jump etc. have the motion of certain rule, and the acceleration transducer in terminal correspondingly can detect the sensed data of rule.Certainly, the sensed data of this rule also needs on the embody rule in conjunction with terminal, if terminal is wearable device (such as Intelligent bracelet, intelligent watch), the sensed data that can there is rule is gone characterizing consumer in walking, runs, jumped; If terminal is intelligent terminal (such as smart mobile phone), the sensed data that also can there is other rule is gone characterizing consumer in walking, runs, is jumped.
Therefore, can arrange and organize sight configuration data for determining the movement scenarios of terminal more, such as many group sight configuration datas determine that terminal user is at static, walking, running, jump etc. movement scenarios respectively.Meet the wherein one group of sight configuration data in sight configuration data when the sensed data of acceleration transducer, then can judge that terminal user is carrying out the corresponding motion of this group sight configuration data.
Usually, when terminal user is when doing fast transfer motion (such as anxious walking is walked, running etc.), because needs ensure positioning precision, thus now need to increase location frequency.So, sight configuration data can be set for determining that terminal is doing fast transfer motion.When the sensed data of acceleration transducer meets this sight configuration data, then can judge that terminal user is carrying out fast transfer motion, namely show that sensed data meets pre-conditioned, can step S130 be performed.
Certainly, also can arrange sight configuration data determination terminal do at a slow speed moving movement (such as take a walk, walk) time, just judge that sensed data meets pre-conditioned, can location frequency be regulated.Now, when terminal user do at a slow speed moving movement time, the sensed data of acceleration transducer senses, just can regulate location frequency, perform step S130.
In certain embodiments, described pre-conditioned also comprise first pre-conditioned.When sensed data meet first pre-conditioned time, implement one-time positioning at once, then according to known location frequency implement secondary location.This is because, if terminal user is when doing fast transfer motion, because position changes rapidly, larger position blank during this period of time may can be there is if do not located at once.Therefore, the first default sight configuration data comprised that regulates can be such as, for determining that terminal user is doing fast transfer motion, runs, rides etc.For acceleration transducer, the sensed data sensed when acceleration transducer meets first and presets the sight configuration data (can be such as be in a scope) regulated, and is namely judged as that sensed data meets first pre-conditioned.Step S130: sensed data meet pre-conditioned after, according to the shift value of terminal between adjacent twice location relative to the increase of basis displacement value or minimizing, corresponding adjustment location frequency makes location frequency improve relative to origin reference location frequency or reduce.The shift value of terminal between adjacent twice location can be determined according to the locator data of adjacent twice location.Fig. 2 is the shift value schematic flow sheet determining terminal between adjacent twice location according to the locator data of adjacent twice location of an embodiment, determines that the process of the shift value of terminal between adjacent twice location specifically comprises the steps: according to the locator data of adjacent twice location
Step S210: drive locating module to perform and locate (first time in above-mentioned adjacent twice location) first to obtain the first geographic position data.First geographic position data can be satellite location data, such as, can be GPS locator data (comprising the locator data of latitude and longitude coordinates data).
Step S220: according to known location frequency, drives locating module to perform secondary location (second time in above-mentioned adjacent twice location) to obtain the second geographic position data.Equally, the second geographic position data can be satellite location data, such as, can be GPS locator data (comprising the locator data of latitude and longitude coordinates data).
Step S230: utilize the coordinate mathematic interpolation of the second geographic position data and the first geographic position data to obtain the shift value of distance as terminal of twice location.Such as, the first geographic position data is (X1, Y1), and the second geographic position data is (X2, Y2), then the shift value that can obtain terminal is
Certainly, the shift value of terminal between adjacent twice location can also be determined according to the sensed data of acceleration transducer between adjacent twice location.
Fig. 3 be an embodiment determine the shift value schematic flow sheet of terminal between adjacent twice location according to the sensed data of acceleration transducer between adjacent twice location, determine that the process of the shift value of terminal between adjacent twice location specifically comprises the steps: according to the sensed data of acceleration transducer between adjacent twice location
Step S310: integral operation is performed to the sensed data of acceleration transducer between adjacent twice location and obtains speed values.By to integrated acceleration computing, speed can be obtained.
Step S320: the shift value that quadratic integral computing obtains terminal between adjacent twice location is performed to speed values.By to rate integrating computing, distance (displacement) can be obtained.
By above-mentioned steps, the shift value of terminal also can be obtained.
Basis displacement value and origin reference location frequency can for presetting; Or basis displacement value and origin reference location frequency can be shift value and the location frequency of terminal between upper adjacent twice location.
When basis displacement value and origin reference location frequency are for presetting, such as basis displacement value can be redefined for S0 (such as 20 meters), and origin reference location frequency can be redefined for F0 (such as 10 seconds/time, i.e. F0=0.1HZ).When the shift value recording terminal between adjacent twice location is S1 (such as 40 meters), now corresponding adjustment location frequency makes location frequency improve relative to origin reference location frequency F0, such as bring up to F1 (such as 5 seconds/time, i.e. F1=0.2HZ).When the shift value recording terminal between adjacent twice location is s1 (such as 10 meters), now corresponding adjustment location frequency makes location frequency reduce relative to origin reference location frequency F0, such as, be reduced to f1 (such as 20 seconds/time).
When basis displacement value and origin reference location frequency are shift value and the location frequency of terminal between upper adjacent twice location, such as basis displacement value can be set as above-mentioned S1 (such as 40 meters), origin reference location frequency can be set as above-mentioned F1 (such as 5 seconds/time, i.e. F1=0.2HZ).When the shift value recording terminal between adjacent twice location is S2 (such as 50 meters), now corresponding adjustment location frequency makes location frequency improve relative to origin reference location frequency F1, such as bring up to F2 (such as 4 seconds/time, i.e. F2=0.25HZ).When the shift value recording terminal between adjacent twice location is s2 (such as 20 meters), now corresponding adjustment location frequency makes location frequency reduce relative to origin reference location frequency F1, such as, be reduced to f2 (such as 10 seconds/time).
When regulating, the amplitude that between adjacent twice location, the shift value of terminal increases relative to basis displacement value or reduces usually is larger, and corresponding adjustment location frequency makes location frequency larger relative to the amplitude of the raising of origin reference location frequency or reduction.Be specially, the amplitude that between adjacent twice location, the shift value of terminal increases relative to basis displacement value is larger, and the amplitude that corresponding adjustment location frequency makes location frequency improve relative to origin reference location frequency is larger; The amplitude that between adjacent twice location, the shift value of terminal reduces relative to basis displacement value is larger, and the amplitude that corresponding adjustment location frequency makes location frequency reduce relative to origin reference location frequency is larger.
Such as, basis displacement value can be redefined for S0 (such as 20 meters), and origin reference location frequency can be redefined for F0 (such as 10 seconds/time, i.e. F0=0.1HZ).When the shift value recording terminal between adjacent twice location is S1 (such as 40 meters), now corresponding adjustment location frequency makes location frequency improve relative to origin reference location frequency F0, such as bring up to F1 (such as 5 seconds/time, i.e. F1=0.2HZ).Calculate in units of HZ, the value of location frequency F1 can be obtained according to the formula of S0/F0=S1/F1.

If the location frequency after regulating is greater than maximum origin reference location frequency Fmax (such as 1 second/time, i.e. Fmax=1HZ), then location frequency is updated to maximum origin reference location frequency Fmax.If the location frequency after regulating is less than minimum reference location frequency Fmin (such as 30 points/time, i.e. Fmin=1/1800HZ), then location frequency is updated to minimum reference location frequency Fmin.Such as, if the location frequency after regulating is 0.5 second/time (2HZ), is greater than maximum origin reference location frequency Fmax, then location frequency is updated to maximum origin reference location frequency Fmax.If the location frequency after regulating is 40 points/time (1/2400HZ), is less than minimum reference location frequency Fmin, then location frequency is updated to minimum reference location frequency Fmin.
If basis displacement value and origin reference location frequency be preset time, need to go initializing set in advance to basis displacement value and origin reference location frequency.And, if when basis displacement value and origin reference location frequency are shift value and the location frequency of terminal between upper adjacent twice location, also need to go initializing set in advance to basis displacement value and origin reference location frequency.Therefore, terminal positioning frequency adjustment method can also comprise previous step S100 before step S110.

The shift value of terminal between adjacent twice location can be determined according to the locator data of adjacent twice location.Fig. 6 is the shift value schematic flow sheet determining terminal between adjacent twice location according to the locator data of adjacent twice location of an embodiment, determines that the process of the shift value of terminal between adjacent twice location specifically comprises the steps: according to the locator data of adjacent twice location
Step S510: drive locating module to perform and locate (first time in above-mentioned adjacent twice location) first to obtain the first geographic position data.First geographic position data can be satellite location data, such as, can be GPS locator data (comprising the locator data of latitude and longitude coordinates data).
Step S520: after known positioning interval, drives locating module to perform secondary location (second time in above-mentioned adjacent twice location) to obtain the second geographic position data.Equally, the second geographic position data can be satellite location data, such as, can be GPS locator data (comprising the locator data of latitude and longitude coordinates data).
Step S530: utilize the coordinate mathematic interpolation of the second geographic position data and the first geographic position data to obtain the shift value of distance as terminal of twice location.Such as, the first geographic position data is (X1, Y1), and the second geographic position data is (X2, Y2), then the shift value that can obtain terminal is
Certainly, the shift value of terminal between adjacent twice location can also be determined according to the sensed data of acceleration transducer between adjacent twice location.
Fig. 3 be an embodiment determine the shift value schematic flow sheet of terminal between adjacent twice location according to the sensed data of acceleration transducer between adjacent twice location, determine that the process of the shift value of terminal between adjacent twice location specifically comprises the steps: according to the sensed data of acceleration transducer between adjacent twice location
Step S310: integral operation is performed to the sensed data of acceleration transducer between adjacent twice location and obtains speed values.By to integrated acceleration computing, speed can be obtained.
Step S320: the shift value that quadratic integral computing obtains terminal between adjacent twice location is performed to speed values.By to rate integrating computing, distance (displacement) can be obtained.
By above-mentioned steps, the shift value of terminal also can be obtained.
Basis displacement value and origin reference location interval can for presetting; Or basis displacement value and origin reference location interval can be shift value and the positioning interval of terminal between upper adjacent twice location.
When basis displacement value and origin reference location be spaced apart preset time, such as basis displacement value can be redefined for S0 (such as 20 meters), and origin reference location interval can be redefined for T0 (such as 10 seconds).When the shift value recording terminal between adjacent twice location is S1 (such as 40 meters), now corresponding adjustment positioning interval makes positioning interval reduce relative to origin reference location interval T 0, such as, reduce to T1 (such as 5 seconds).When the shift value recording terminal between adjacent twice location is s1 (such as 10 meters), now corresponding adjustment positioning interval makes positioning interval increase relative to origin reference location interval T 0, such as, increase to t1 (such as 20 seconds).
When basis displacement value and origin reference location are spaced apart shift value and the positioning interval of terminal between upper adjacent twice location, such as basis displacement value can be set as above-mentioned S1 (such as 40 meters), and origin reference location interval can be set as above-mentioned T1 (such as 5 seconds).When the shift value recording terminal between adjacent twice location is S2 (such as 50 meters), now corresponding adjustment positioning interval makes positioning interval reduce relative to origin reference location interval T 1, such as, reduce to T2 (such as 4 seconds).When the shift value recording terminal between adjacent twice location is s2 (such as 20 meters), now corresponding adjustment positioning interval makes positioning interval increase relative to origin reference location interval T 1, such as, increase to t2 (such as 10 seconds).
When regulating, the amplitude that between adjacent twice location, the shift value of terminal increases relative to basis displacement value or reduces usually is larger, and corresponding adjustment positioning interval makes positioning interval larger relative to the amplitude of the minimizing of origin reference location interval or increase.Be specially, the amplitude that between adjacent twice location, the shift value of terminal increases relative to basis displacement value is larger, and the amplitude that corresponding adjustment positioning interval makes positioning interval reduce relative to origin reference location interval is larger; The amplitude that between adjacent twice location, the shift value of terminal reduces relative to basis displacement value is larger, and the amplitude that corresponding adjustment positioning interval makes positioning interval increase relative to origin reference location interval is larger.
Such as, basis displacement value can be redefined for S0 (such as 20 meters), and origin reference location interval can be redefined for T0 (such as 10 seconds).When the shift value recording terminal between adjacent twice location is S1 (such as 40 meters), now corresponding adjustment positioning interval makes positioning interval reduce relative to origin reference location interval T 0, such as, reduce to T1 (such as 5 seconds).The value of positioning interval T1 can be obtained according to the formula of S0 × T0=S1 × T1.
Certainly, the adjustment of positioning interval needs in certain scope, and after all for location, positioning interval has certain scope, and too small positioning interval both may not supported by locating module, also caused power consumption excessive; Excessive positioning interval then causes positioning precision not high.Therefore, when regulating, need to carry out suitable restriction to the size of positioning interval.Method for limiting is as follows:
If the positioning interval after regulating is greater than maximum origin reference location interval T max (such as 30 minutes), then positioning interval is updated to maximum origin reference location interval T max.If the positioning interval after regulating is less than minimum reference positioning interval Tmin (such as 1 second), then positioning interval is updated to minimum reference positioning interval Tmin.Such as, if the positioning interval after regulating is 0.5 second, is less than in minimum reference positioning interval Tmin (1 second), then positioning interval is updated to minimum reference positioning interval Tmin (1 second).If the positioning interval after regulating is 40 minutes, is greater than maximum origin reference location interval T max (30 points), then positioning interval is updated to maximum origin reference location interval T max (30 points).
If basis displacement value and origin reference location be spaced apart preset time, need to go initializing set in advance to basis displacement value and origin reference location interval.And, if when basis displacement value and origin reference location are spaced apart shift value and the positioning interval of terminal between adjacent twice location, also need to go initializing set in advance to basis displacement value and origin reference location interval.Therefore, terminal positioning interval regulating system also comprises presetting module 400, for carrying out initializing set in advance to basis displacement value and origin reference location interval.
Above-mentioned to carry out initializing set in advance to basis displacement value and origin reference location interval both can be that user sets, and also can be just to preset when product design.Certainly, if just preset when product design, now also basis displacement value and origin reference location interval can be changed voluntarily by user.Therefore, presetting module 400 can provide user interface for receiving the initializing set in advance to basis displacement value and origin reference location interval, and user can carry out initializing set or change in advance to basis displacement value and origin reference location interval by user interface.
Above-mentioned terminal positioning interval control method and system, the motion of identification terminal user is carried out according to the sensed data of acceleration transducer, then terminal regulates positioning interval according to the motion state of user, makes terminal positioning both can ensure positioning precision, also can ensure lower power consumption.Above-mentioned terminal can be wearable device, such as, can be Intelligent bracelet or intelligent watch; Can certainly be intelligent terminal, such as, can be smart mobile phone.When user carries above-mentioned terminal, be connected with above-mentioned terminal communication other people can know the situation of user.Such as when user be children or old man time, the guardian of user can understand the situation of user more accurately, and above-mentioned terminal has lower power consumption relative to traditional terminal, improve the flying power of terminal, and positioning precision is guaranteed.
