Background technology
At present, the product that possesses navigation feature is more and more, and its range of application is also more and more wider, and people when offering convenience, also run into some problems through regular meeting in enjoyment GPS navigation (Global Positioning System, GPS).
For example, when the user travelled on viaduct and viaduct, the GPS terminal was sent wrong navigation instruction through regular meeting, as, in the cruising, the GPS terminal points out the driver to turn right suddenly on viaduct, but does not have the outlet of right-hand rotation on the bridge at all.This is that actual residing position is not on the bridge or under the bridge because the GPS terminal is accurately judged vehicle, thereby has sent wrong instruction.
Because the restriction of GPS location technology and other factors at present, the sea level elevation value error that the GPS terminal is calculated reaches tens meters, and the two-layer difference in height up and down of general viaduct and viaduct is usually also just several meters to ten meters scope, because the GPS terminal is calculated on its navigation map less than altitude information, so directly the viaduct of three-dimensional is handled as the intersection of two dimension, add the horizon location error of GPS terminal, thereby the wrong phenomenon that judges of bridge on the bridge can often occur.
Make troubles when the navigation instruction of above-mentioned mistake not only can be driven a vehicle to the user, and if the user operate possibly according to navigation instruction fully and cause danger.
Thereby existing GPS navigation technology is still waiting to improve and improve.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art part, the object of the present invention is to provide a kind of portable terminal that possesses the GPS navigation function, can accurately draw the residing three dimensional local information of portable terminal.
In order to achieve the above object, the present invention has taked following technical scheme:
A kind of portable terminal that possesses the GPS navigation function, it comprises the GPS module of the horizontal position information that is used to obtain portable terminal, wherein, also comprise the pressure detection module of the atmospheric pressure information that is used for obtaining in real time portable terminal and be used for, draw the control module of the 3 D stereo positional information of portable terminal according to described horizontal position information and atmospheric pressure information; Described pressure detection module is connected with control module respectively with the GPS module.
The described portable terminal that possesses the GPS navigation function, wherein, described pressure detection module comprises pressure transducer and ADC unit, described pressure transducer is connected with control module by the ADC unit.
The described portable terminal that possesses the GPS navigation function, wherein, described portable terminal is a GPS terminal.
The described portable terminal that possesses the GPS navigation function, wherein, described portable terminal is a mobile phone.
A kind of portable terminal that possesses the GPS navigation function provided by the invention, owing to adopted the pressure detection module that is used to detect atmospheric pressure, can obtain the atmospheric pressure of portable terminal present position in real time, make control module calculate portable terminal present position sea level elevation according to the corresponding relation of this atmospheric pressure and sea level elevation, the horizontal position information that while obtains according to the GPS module, draw the residing 3 D stereo information of portable terminal, give portable terminal accurately location and navigation, thereby can guide the driver on viaduct and viaduct, correctly to travel, for driver's safety provides powerful guarantee.In addition, portable terminal of the present invention can also provide sea level elevation accurately for the climber, give people the outdoor activities band more convenience and enjoyment.
