Embodiment
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, contrast accompanying drawing is illustrated the specific embodiment of the present invention below.Apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, and obtain other execution mode.
For making simplified form, only schematically show part related to the present invention in each figure, they do not represent its practical structures as product.In addition, be convenient to make simplified form understand, there are the parts of same structure or function in some figure, only schematically depict one of them, or only marked one of them.In this article, " one " not only represents " only this ", also can represent the situation of " more than one ".
Fig. 1 is the key step schematic diagram of a kind of mobile terminal date and time of the present invention bearing calibration.As a specific embodiment of the present invention, as shown in Figure 1, the bearing calibration of a kind of mobile terminal date and time, comprising:
When receiving acquisition instructions, obtain the first information of mobile terminal;
Analyze and calculate the described first information, obtaining local time information and the date and time information of mobile terminal;
Zone time and the date of mobile terminal is upgraded according to described local time information and described date and time information.
Concrete, the described first information comprises the latitude and longitude information of described mobile terminal, azimuth information and elevation angle information; Described elevation angle information comprises the angle of mobile terminal with solar core line and ground level; Described azimuth information comprise mobile terminal with the projection of solar core line on ground level and Due South between angle.
Concrete, azimuth α represents, computing formula is
α=arcsin [sin δ sin Φ+cos δ cos ω cos Φ] (one),
Wherein, δ is declination angle, and ω is solar hour angle,
for the latitude of locality.
Concrete, elevation angle r represents, computing formula is
(2)
δ declination angle can be calculated, ω solar hour angle according to computing formula (one) (two).
Concrete, declination angle, also known as solar declination, is earth equatorial plane and the angle between the sun and the line of earth center.Declination angle is the phenomenon caused because the earth moves round the sun, and it becomes in time, because ground direction of principal axis is constant, so declination angle has different numerical value with the difference of the earth on orbit.Declination angle take year as the cycle, moves, become the mark in season in+23 ° of 26 ' scope with-23 ° 26 '.Declination reached maximum+23 ° 26 ' and was called the Summer Solstice annual June 21 or 22 days, and this day noon, the sun was positioned at the positive overhead of the earth tropic of cancer, was the longest, the shortest one day of Southern Hemisphere hours of daylight Northern Hemisphere hours of daylight.In the Antarctic circle, all day can not see the sun, and the sun does not fall all day in the Arctic Circle, and relatively hot weather just appears in such Northern Hemisphere, and colder weather appears in the Southern Hemisphere.Declination angle is gradually reduced to time round the clock in whole world when equalling zero September 21 or 22 days all equal is subsequently the Autumnal Equinox.Reduce to minimum value-23 ° 26 for Winter Solstice to December 21 or 22 days declination, the now sunlight oblique fire Northern Hemisphere, days are short and nights long, and the Southern Hemisphere is then contrary.Be the Spring Equinox and March 21 or 22 days when zero degree is got back to again at declination angle, so go round and begin again and form the four seasons.According to the meaning of definition, this angle major part is Space Angle, the angle of different surface beeline.
Concrete, the hour angle at Mian center, sun visual angle, namely from observation station celestial meridian along celestial equator amount to the angular distance of the sun place hour circle.
For the earth, on earth, synchronization, to same longitude, the people of different latitude, the hour angle that the sun is corresponding is identical.The angle of unit interval earth rotation is defined as hour angle ω, and regulation hour angle at high noon is 0, and the morning, hour angle was negative value, afternoon hour angle be on the occasion of.Earth rotation tour, the corresponding time is 24 hours, and namely corresponding hour angle per hour is 15 degree.
Above-described embodiment is improved, also comprised before the first information obtaining mobile terminal:
The view data of the Real-time Collection sun;
Described view data is processed and judges; When judging that described view data meets acquisition condition, send acquisition instructions for obtaining the first information of mobile terminal.
Concrete, described acquisition condition is specially: analyze and view data described in comparison and the benchmark image prestored, when similarity reaches predetermined threshold value, judge that described view data meets acquisition condition.
Above-described embodiment is improved, wherein specifically comprises according to the zone time of described local time information renewal mobile terminal:
Time difference information corresponding to time zone, mobile terminal place is calculated according to latitude and longitude information;
The zone time of mobile terminal is obtained according to described time difference information and described local time information;
Described zone time is updated to the time of mobile terminal.
Concrete, according to calculating the date, its specific formula for calculation is:
Be wherein n date sequence number, such as, when the date is January 1, n=1, when the date is March 22, n=81.
Again according to calculating true solar time ST, specific formula for calculation: ω=15 × (ST-12) (four)
Wherein ST was the true solar time, in 24 hours.It is noted that in CHINESE REGION, what often adopt is Beijing time, is not local time (true solar time).Chinese Regional is wide, and the thing time difference is maximum reaches 4h, when carrying out Sunlight Analysis, should adopt the local time.
From astronomically, the time can be divided into mean solar time and true solar time.
Mean solar time is exactly give the correct time the time in the countries and regions of reference at ordinary times, and as Beijing time, the time interval of its every day is equal.True solar time is positioned at the instantaneous for high noon of positive south orientation with the local sun.Because the Distance geometry relative position between the sun and the earth is in time in change, and place's plane of terrestrial equator and its track run around the sun is inconsistent, thus always difference to some extent between time (mean solar time) of indicating of true solar time and clock and watch, their difference is the time difference.The maximum time difference can reach 16min.4 time differences are only had to be zero in 1 year.True solar time should be adopted when calculating position of sun.
In CHINESE REGION, the reduction formula of true solar time is
True solar time (ST)=Beijing time+time difference (five)
The time difference=(120 °-local longitude)/15 ° (six)
The time difference of current time zone can be obtained by the latitude and longitude information of mobile terminal position, the time of current time zone can be obtained according to the time difference and true solar time.
