Embodiment 1
The method that a kind of reduction wearable device positioning power consumption that the embodiment of the present invention 1 provides ensures positioning accuracy, including with
Lower step:
S1, wearable device acquisition position information；
Collected location information is sent center calculation server by S2, wearable device, and history bit shift-in row is clear
Zero；
S3, wearable device acquire related data by sensing device, and are displaced number by correlation data calculation wearable device
According to；
By the calculated displacement data of wearable device compared with preset displacement threshold value, if being more than preset displacement threshold value,
Then re-start location information acquisition；If being less than preset displacement threshold value, wearable device calculates central server and receives " not
After movement " event, no longer needs to carry out further data calculating, the location point of equipment the last time can be used.
It should be noted that, if not collecting position data, entering of short duration suspend mode when wearable device acquisition position information
State, waiting acquire next time, location information acquisition include by wearable device search periphery WiFi, BSSID, SSID, signal,
One or more of base station information collection, GPS and Beidou information carry out networking and calculate positioning.
Preferably, sensing device include be arranged in wearable device with the gyro sensor of mainboard data connection, six
The one or more of axle sensor and nine axle sensors, for calculating whether current device generated acceleration；If generating acceleration
Degree then calculates center calculation and goes out the displacement generated in the corresponding period.
Preferably, it if wearable device does not generate acceleration, without data collection effort, collects or adopts for reducing
Energy consumption caused by collecting, the related data of sensing device acquisition are acceleration value.
Specific: in view of not can increase other power consumptions of wearable device, entire method only used wearable device itself
Some low-power consumption sensors do not increase other energy consumptions additionally, but needing wearable device includes one or more angular speed or acceleration
Spend sensing device；
Firstly, wearable device is after powering, the information collection of first time will be carried out, and information is transferred into scheming in calculating
It calculates, obtains an initial position data P1；
Then, wearable device enters period acquisition phase, period t1Interior wearable device will handle sensor with period t2It holds
The continuous information collected:
It is as follows to handle preacceleration data:
{ instantaneous acceleration a1}
{ instantaneous acceleration a2}

(2) again by the displacement in each periodSummation obtains total displacement s, t1In period, the displacement of wearable device maximum possible
Amount:
By obtained this period total displacement s, then with the displacement number o added up this period was navigated to since last time
The result of addition is compared with a settable threshold value d, if being less than threshold value, then it is assumed that the wearable device " does not move
It is dynamic "；
If wearable device " does not move ", by o=o+s more new historical accumulative displacement, this will not start location information
Collect, reduce this acquisition expense, wearable device will " not move " information such as event and current time stamp wearable device identify,
Event: time does not move } it is advertised to calculating center, calculating center, will be directly using last position without being again started up calculating
Data P1, and renewal time stabs；
If wearable device moves, and carries out according to original acquisition calculation process, accumulative displacement numeration resets o=0,
Details are not described herein again.
Do not increase additional external detection device, does not need from external data；Only with the existing sensing of wearable device
Device；The total calculation of data group that can be a sensor or multiple sensors, obtains a speed and duration, Jin Erji
A mobile possible section is calculated, if being no more than a settable threshold value, then it is assumed that the interior wearable device of current period is not
It moves: by judging whether equipment moves, to reduce information collection/acquisition number, reducing the power consumption of wearable device, such as
It reduces Beidou/GPS and searches magnitude power consumption；When wearable device is periodically detected equipment and does not move, when by current device mark, detection
Between and " not moving " event, central server is informed by message mechanism；After central server receives " not moving " event, center
Server updates the equipment state using the temporal information and the location point of wearable device the last time of the event；Due to reducing
By the calculating of the information such as such as base station GPS/WiFi/, achieve the purpose that reduce calculating energy consumption, while reducing as calculated error
And GPS the problems such as floaing, ensure positioning accuracy；Wearable device acquisition power consumption can be effectively reduced, reduces and calculates center calculation
Expense ensures positioning accuracy, reduces the problem of wearable device occurs floaing when static.
Embodiment 2
The method that a kind of reduction wearable device positioning power consumption that the embodiment of the present invention 2 provides ensures positioning accuracy, please refers to
Shown in Fig. 1, comprising the following steps:
Step 1, wearable device enters when initializing to be acquired for the first time, and is just calculated center calculation in notice and gone out present bit
After setting P1, initial accumulative displacement resets o=0, into collection period t1。
Step 2 collects each t using sensor2The instantaneous acceleration in period, by being laterally accelerated after operation
Spend ai, as shown in Figure 2.
Step 3 passes through acceleration aiSubstitute into formulaCalculate each t2The displacement variable in period,
As shown in Figure 3.
Step 4, add up t1The interior calculated displacement variable of all the sensors, obtains displacement total in the time range
S is measured, as shown in Figure 4.
Step 5, total displacement amount and history bit phase shift add to obtain new total displacement o=o+s, with preset displacement threshold
Value compares, if being not more than the threshold value, then it is assumed that the period inner sensor does not generate movement, and wearable device will send " not moving "
It after time gives calculating central server, calculating central server to receive the event, is not repeated to calculate, directly using the last time
Position only updates this event time.
If displacement is greater than the threshold value of setting, continue former acquisition positioning basic information, and be sent to and calculate center calculation stream
Journey is not repeated herein.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
