Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
One embodiment of the invention provides a kind of method for obtaining relative altitude, and the method is applied to electronic equipment, such as Fig. 1
Shown, the method includes：
101st, the atmospheric pressure value of electronic equipment local environment is obtained.
Wherein, the atmospheric pressure value is performed by the sensing unit for including in electronic equipment.
102nd, when the change when above-mentioned atmospheric pressure value in scheduled time length is maintained within first threshold, the first gas is determined
Pressure a reference value.
Optionally, above-mentioned first air pressure a reference value is contained in above-mentioned first threshold or one group of atmospheric pressure value.
Optionally, it is determined that also including setting the first threshold before the first air pressure a reference value.Preferably, first threshold
Value refers to the atmospheric pressure value of the starting point of height to be measured, when electronic equipment does not exist relative altitude, or relative altitude in local environment
When differing minimum, atmospheric pressure value now is obtained by sensing unit, and sets the atmospheric pressure value of the acquisition and be set to first threshold, and not
The first threshold is different in same environment.
Further, when the current gas pressure value that sensing unit is obtained exceeds first threshold, following 103 are performed.
103rd, according to current gas pressure value and the first air pressure a reference value of determination, relative altitude is obtained.
Specifically, the first air pressure a reference value is the air pressure that electronic equipment is in initial point position, current gas pressure value is electronics
The air pressure in final position at equipment；And acquire relative altitude with the corresponding relation of height change according to air pressure value changes.
For example, if necessary to the difference in height between measurement position A and position B, and determining that position A is starting point, position B is for eventually
Point, then the first air pressure a reference value represents the atmospheric pressure value of position A, current gas pressure value represents the atmospheric pressure value of position B.Further,
According to air pressure with the variation relation of height, such as, within the km of height above sea level 2,12 meters are often raised, atmospheric pressure reduces by 1 millimetres of mercury, from
And obtain the relative altitude of A and B.
Optionally, the atmospheric pressure value of the electronic equipment local environment for being got according to sensing unit, can also carry out following behaviour
Make：
When a, current gas pressure value exceed first threshold, the first model is drawn according to the atmospheric pressure value for acquiring.
What deserves to be explained is, the first model is the curve drawn according to atmospheric pressure value.
B, judge whether the first model meets second condition.
What deserves to be explained is, perform b judgement before, set up preset model, the preset model represent atmospheric pressure with
The variation relation of height.Above-mentioned b is then performed specifically, judging whether the first model is contained in preset model.
Additionally, preset model represents the variation relation of air pressure and altitude, it is preferred that the preset model passes through rectangular co-ordinate
System represents, and it is position to set abscissa, and ordinate is atmospheric pressure value.The preset model at least includes following three kinds of forms：
The first form：People when normal roadside travels, walks about, the smooth variation of air pressure, as shown in Fig. 2-1；
Optionally, in can setting now curve, the maximum of air pressure and the minimum value of air pressure, as the end points of first threshold.
And in the Fig. 2-1, the change of the positional representation horizontal level of abscissa.
Second form：When stair climbing, with the slow uniform descent of increase pressure values of stair exponent number, as shown in Fig. 2-2；

What deserves to be explained is, in above-mentioned Fig. 2-2,2-3, there is the position of difference in height in the position shown in weighing apparatus coordinate, expression
The change put, that is to say, that the direction height that abscissa arrow is pointed to is increased.
Other any one or a few forms can also be included according to actual conditions preset model.
C, when it is determined that the first model is contained in preset model, perform above-mentioned 103.
Preferably, the situation gone upstairs with reference to described in above-mentioned b, the data before upper first rank stair are the first air pressure
A reference value, the atmospheric pressure value of current position acquisition is current gas pressure value.
What deserves to be explained is, the atmospheric pressure value got according to sensing unit draws the first model, by with preset model
Matching, can know current motion state.
Further, after above-mentioned relative altitude is got, electronic equipment can show the relative altitude to user.
A kind of method for obtaining relative altitude provided in an embodiment of the present invention, the method is applied to electronic equipment, in electronics
Sensing unit in equipment is acquired after the atmospheric pressure value for representing local environment, and when the atmospheric pressure value is in scheduled time length

, during stair climbing with reference to described in above-mentioned b air pressure with stair exponent number change curve, due to before going upstairs in flat
Ground, that is to say, that atmospheric pressure value now is contained within first threshold, then air pressure change represented by curve, as horizontal line or
The curve that person changes by a small margin, when going upstairs, air pressure starts to reduce, then the critical point for reducing air pressure to by level is made
It is the first air pressure a reference value selected point.
Further, if user is in position higher than the second layer, and fixed by the height between floor, now
According to known story height and the relative altitude for getting, and then the number of floor levels that position is located at can be got, or
Person combines change curve of the air pressure with stair exponent number, in addition to ground floor, as soon as place's air pressure level often occur goes to decline, illustrates to use
Family switchs to stair climbing state by level land, then can be according to the secondary of the curve drawn by the atmospheric pressure value namely change of the first model
