Fig. 3 is the flow chart of gyroscope processing method in one embodiment.Gyroscope processing method in the present embodiment, with
It is described for running on the electronic equipment in Fig. 1.As shown in figure 3, gyroscope processing method includes step 302 to step
308。
Step 302, the electricity of electronic equipment is detected.
Electricity refers to the electrically charged quantity of electronic equipment.The electrically charged quantity of electronic equipment is more, indicates electronics
The electricity of equipment is more, and the electrically charged quantity of electronic equipment is fewer, indicates that the electricity of electronic equipment is fewer.Generally, it indicates
The electricity of electronic equipment can use percentage, such as 50%；Figure can also be used, the electricity of half can be expressed as container image
Half is filled, and in addition half is empty image, without being limited thereto.
In one embodiment, when the electricity of electronic equipment is lower, prompt information, such as light flash can be generated, text
Word barrage information, vibration etc. are without being limited thereto.
Specifically, detect electronic equipment electricity can by the methods of voltage test method, fuel cell modelling method, Coulomb meter into
Row detection.Wherein, voltage test method refers to that the electricity of battery passes through the voltage for simply monitoring battery, according to the voltage of battery
Size it can be concluded that battery electricity.Fuel cell modelling method refers to establishing a tables of data according to the discharge curve of battery,
The charge value under different voltages can be indicated in tables of data.Coulomb meter is anode and cathode one galvanoscopy electricity of series connection in battery
Resistance, voltage (Vsense) will be generated when there is electric current to flow through galvanoscopy resistance, by detecting voltage (Vsense)
The electric current for flowing through battery is calculated, to obtain the electricity of battery.The method of detection electricity does not limit, and specifically detects electricity
Method can be set according to user demand.
Step 304, when electricity is lower than power threshold, the value of the acquisition parameter of the gyroscope in electronic equipment is adjusted,
In, acquisition parameter includes at least one of the quantity of sample frequency, measurement range, measurement accuracy, measurement direction.
Gyroscope is called angular-rate sensor, can measure rotational angular velocity when electronic equipment deflection, inclination.Gyroscope
Including fibre optic gyroscope, lasergyro, MEMS (Micro Electro Mechanical systems, mems
System) gyroscope etc..Gyroscope in above-mentioned gyroscope processing method can be fibre optic gyroscope, lasergyro, MEMS gyro
Instrument etc., it is without being limited thereto.
When detecting the electricity of electronic equipment lower than power threshold, the acquisition parameter of the gyroscope in electronic equipment is adjusted
Value, at least one of the sample frequency of adjustable gyroscope, measurement range, measurement accuracy, quantity of measurement direction.It adjusts
After the value of the sampling parameter of gyroscope in whole electronic equipment, the power consumption of gyroscope can be reduced.Such as reduce adopting for gyroscope
Sample frequency, then gyroscope acquires less data in identical duration, reduces the power consumption of gyroscope, to save electronics
The electric quantity consumption of equipment.
It in one embodiment, can also be by closing electronic equipment when the electricity of electronic equipment is lower than power threshold
In other applications or stop the work of other components, to save the electricity of electronic equipment.
Step 306, when acquisition parameter includes measurement accuracy, increase the value of measurement accuracy.
It is understood that measurement accuracy is smaller, indicates that gyroscope data collected are more accurate, then gyroscope is wanted
It asks higher, needs to expend more power consumptions.For example, indicating angular velocity data measured by gyroscope when measurement accuracy is 0.1
Between minimal difference can be 0.1；And when measurement accuracy is 0.01, it indicates between angular velocity data measured by gyroscope
Minimal difference can be 0.01, the precision of gyroscope angular velocity data collected must be extremely accurate to 2 significant digits.
Therefore, when detecting the electricity of electronic equipment lower than power threshold, the value of measurement accuracy can be increased, to drop
The accuracy of low gyroscope data collected, reduces the power consumption of gyroscope.
In one embodiment, the vibration frequency of reduction gyroscope, the value of Lai Zeng great measurement accuracy can be passed through.In gyro
In instrument, vibration frequency is bigger, can measure more accurate shake, i.e. gyroscope angular velocity data collected is more accurate.
When reducing the vibration frequency of gyroscope, then the precision of angular velocity data measured by gyroscope is larger, to increase gyro
The value of the measurement accuracy of instrument.
In another embodiment it is also possible to increase the value of measurement accuracy by other means, concrete mode can root
It is set according to user, it is without being limited thereto.
Step 308, when acquisition parameter includes at least one of the quantity of sample frequency, measurement range, measurement direction,
Accordingly reduce at least one in the value, the value of measurement range, the quantity of measurement direction of sample frequency included by acquisition parameter
Kind.
It is understood that sample frequency is smaller, the angular velocity data for indicating that gyroscope acquires within the unit time is fewer,
The power consumption of gyroscope can be reduced.For example, the sample frequency of gyroscope is acquisition 100 times per second, when the sample frequency of gyroscope
When being acquisition 50 times per second, then gyroscope is interior at the same time, and in 1 second, gyroscope reduces 50 angular speed of acquisition
Data reduce the power consumption of gyroscope.
Measurement range is smaller, indicates that the range for the shake that gyroscope can measure is smaller.For example, measurement range is 1-3 degree,
The range for indicating the shake that gyroscope is capable of measuring is between 1 degree to 2 degree；When measurement range is spent for 2-3, gyroscope institute is indicated
When the range for the shake being capable of measuring between 2 degree to 3 degree, it is not capable of measuring less than 2 degree and shake is greater than 3 degree of shake.Therefore,
The value for reducing measurement range can reduce the power consumption of gyroscope.
There are three rotary shafts for setting in gyroscope, then the measurement direction of gyroscope can be divided into three pairs of measurement sides
To every a pair of measurement direction includes the opposite measurement direction of both direction, i.e., the measurement direction of gyroscope can be 6.Work as inspection
When measuring the electricity of electronic equipment lower than power threshold, the quantity of gyroscope measurement direction can be reduced, then gyroscope can be surveyed
The angular velocity data in small number of measurement direction is measured, the angular velocity data in the whole measurement direction of measurement is not needed,
To reduce the power consumption of gyroscope.
For example, the measurement direction of gyroscope is 6, when the measurement direction of gyroscope is reduced to 2, then only need to measure
Angular velocity data in 2 measurement directions, reduces the power consumption of gyroscope.
It is understood that being provided in gyroscope is three rotary shafts, there are three pairs of measurement directions, every a pair of measurement direction
Include the opposite measurement direction of both direction.Then the quantity of the measurement direction of gyroscope is even number, and measurement direction is pairs of
Measurement direction.For example, then 2 measurement directions are pairs of measurement direction when the quantity of measurement direction is 2.
When acquisition parameter includes one of the quantity of sample frequency, measurement range, measurement direction, then accordingly reduce
The value of parameter included by acquisition parameter.For example, reducing the value of sample frequency when acquisition parameter includes sample frequency.When adopting
When collection parameter includes the quantity of measurement direction, the quantity of measurement direction is reduced.
When a variety of in the quantity that acquisition parameter includes sample frequency, measurement range, measurement direction, i.e., two kinds or three kinds
When, then accordingly reduce the value of at least one parameter included by acquisition parameter.For example, when acquisition parameter include sample frequency,
When measurement range, the value of sample frequency can be only reduced, can also only reduce the value of measurement range, can also reduce sampling frequency
The value of rate and the value of measurement range.
Above-mentioned gyroscope processing method, detects the electricity of electronic equipment, and when electricity is lower than power threshold, adjustment electronics is set
The value of the acquisition parameter of gyroscope in standby increases the value of measurement accuracy, measurement accuracy when acquisition parameter includes measurement accuracy
It is bigger, it is smaller to the precision measure requirement of gyroscope, then it can reduce the power consumption of gyroscope；When acquisition parameter includes sampling frequency
When at least one of rate, measurement range, quantity of measurement direction, sample frequency included by acquisition parameter is accordingly reduced
At least one of value, the value of measurement range, the quantity of measurement direction, the value for reducing sample frequency makes gyroscope identical
Less data are obtained in time, the value for reducing measurement range makes gyroscope measure smaller range, reduces measurement direction
Quantity makes gyroscope acquire the data in less direction, therefore reduces the power consumption of gyroscope.
As shown in figure 4, in one embodiment, when electricity is lower than power threshold, adjusting the gyroscope in electronic equipment
Acquisition parameter value, comprising:
It step 402, will be in electronic equipment when electricity is lower than the first power threshold and is greater than or equal to the second power threshold
The value of acquisition parameter of gyroscope be adjusted to the first numerical value, wherein the first power threshold is greater than the second power threshold.
First power threshold be greater than the second power threshold, when electronic equipment electricity lower than the first power threshold and be higher than or
When equal to the second power threshold, indicate that the electricity of electronic equipment remains at low levels, then by the gyroscope in electronic equipment
The value of acquisition parameter is adjusted to the first numerical value.Wherein, the first power threshold and the second power threshold can be needed according to user into
Row setting, it is without being limited thereto.
Step 404, when electricity is lower than the second power threshold, by the value tune of the acquisition parameter of the gyroscope in electronic equipment
Whole is second value, wherein the first numerical value of measurement accuracy is less than corresponding second value, and the first numerical value of sample frequency is greater than
Corresponding second value, measurement range the range of the first numerical value be greater than the number of the range of corresponding second value, measurement direction
First numerical value of amount is greater than corresponding second value.
When electricity is lower than the first power threshold and is greater than or equal to the second power threshold, indicate at the electricity of electronic equipment
In lower level；When electricity is lower than the second power threshold, indicate that the electricity of electronic equipment is in lower level.It then can be with
Value according to the acquisition parameter of the different electricity adjustment gyroscope of electronic equipment is different value, can make the electricity of electronic equipment
Amount is lower than the first power threshold and when being greater than or equal to the second power threshold, still available more accurate or more angle speed
Degree evidence；When so that the electricity of electronic equipment being lower than the second power threshold, the acquisition parameter of gyroscope is adjusted to second value,
To reduce the power consumption of gyroscope.
For example, can set the first power threshold to 20%, the second power threshold is set as 10%, then when electricity is lower than
First power threshold and it is greater than or equal to the second power threshold, i.e. the electricity of electronic equipment is between 10%-20%, and electronics is set
Standby electricity remains at low levels, and can maintain the operation of electronic equipment, and the acquisition parameter of gyroscope can be adjusted to
One numerical value, to obtain more accurate or more angular velocity data.When electricity is lower than the second power threshold, the i.e. electricity of electronic equipment
When amount is in 10%, the electricity of electronic equipment is in lower level, and electronic equipment may be because not enough power supply at any time and shut down,
The acquisition parameter of gyroscope is then adjusted to second value, to reduce the power consumption of gyroscope.
It therefore, will be in electronic equipment when electricity is lower than the first power threshold and is greater than or equal to the second power threshold
The value of the acquisition parameter of gyroscope is adjusted to the first numerical value；When electricity is lower than the second power threshold, by the top in electronic equipment
The value of the acquisition parameter of spiral shell instrument is adjusted to second value.Wherein, the power consumption of gyroscope when acquisition parameter is the first numerical value, is greater than
The power consumption of gyroscope when acquisition parameter is second value.
Specifically, the first numerical value of measurement accuracy is less than corresponding second value.When the value of the measurement accuracy of gyroscope is
When the first numerical value, more accurate angular velocity data is measured, needs to expend bigger power consumption；When the value of the measurement accuracy of gyroscope
When for second value, power consumption can be reduced with the biggish angular velocity data of measurement accuracy.
First numerical value of sample frequency is greater than corresponding second value.When the value of the sample frequency of gyroscope is the first numerical value
When, gyroscope acquires more angular velocity data, needs to expend biggish power consumption；When the value of the sample frequency of gyroscope is second
When numerical value, less angular velocity data can be acquired, reduces the power consumption of gyroscope.
The range of first numerical value of measurement range is greater than the range of corresponding second value.When the measurement range of gyroscope is
When the first numerical value, the range of the angular velocity data of gyroscope acquisition is larger, needs to expend biggish power consumption；When the measurement of gyroscope
When range is second value, the range of the angular velocity data of gyroscope acquisition is smaller, reduces power consumption.
It is understood that the first numerical value and second value of measurement range are an interval value, the range of interval value can
It is without being limited thereto to be set according to user.
First numerical value of the quantity of measurement direction is greater than corresponding second value.When the quantity of the measurement direction of gyroscope is
When the first numerical value, gyroscope acquires the angular velocity data in more measurement direction, needs to expend biggish power consumption；When gyroscope
When the quantity of measurement direction is second value, gyroscope acquires the angular velocity data in less measurement direction, reduces gyroscope
Power consumption.
Above-mentioned gyroscope processing method, when electricity is lower than the first power threshold and is greater than or equal to the second power threshold,
The value of the acquisition parameter of gyroscope in electronic equipment is adjusted to the first numerical value；It, will when electricity is lower than the second power threshold
The value of the acquisition parameter of gyroscope in electronic equipment is adjusted to second value, can be according to different electricity adopting gyroscope
The value of collection parameter is adjusted to different values, to realize that the power consumption of gyroscope is balanced with the angular velocity data that gyroscope acquires.
In one embodiment, when acquisition parameter includes the quantity of measurement direction, the quantity of measurement direction is reduced, is wrapped
It includes:
Step 502, when acquisition parameter includes the quantity of measurement direction, the of gyroscope in each measurement direction is acquired
One angular velocity data.
It is understood that the quantity of the measurement direction of gyroscope is even number, and measurement direction is pairs of measurement direction.
The quantity of the measurement direction of gyroscope is at least 2, i.e., at least a pair of of measurement direction.When the quantity of the measurement direction of gyroscope
When being 0, indicate that gyroscope stops working, there is no the angular velocity datas in any one measurement direction of acquisition.
Step 504, target side is determined from each measurement direction according to the first angular velocity data in each measurement direction
To, wherein quantity of the quantity of target direction lower than whole measurement directions of gyroscope.
First angular velocity data of the gyroscope in each measurement direction is acquired, according to first jiao in each measurement direction
Speed data determines target direction from each measurement direction.Similarly, the quantity of target direction is also even number, and target direction is
Pairs of measurement direction, and the quantity of target direction reduces measurement side lower than the quantity of whole measurement directions of gyroscope
To quantity.
Above-mentioned gyroscope processing method acquires gyroscope in each side when acquisition parameter includes the quantity of measurement direction
The first upward angular velocity data determines target direction according to the first angular velocity data in all directions from all directions,
The quantity of target direction reduces the quantity of measurement direction, to reduce gyro lower than the quantity in whole directions of gyroscope
The power consumption of instrument.
In one embodiment, target side is determined from all directions according to the first angular velocity data in all directions
To, comprising:
