Abstract
The invention discloses a mobile terminal capable of being positioned under the condition of a weak positioning signal and a method for positioning the same. The mobile terminal comprises a control unit and a display screen, a speaker, a key, a storage unit, a GPS (Global Positioning System) positioning module, an acceleration sensor and a gyroscope which are connected with the control unit. The positioning method comprises the following steps of: under the condition that a satellite positioning signal is effective and available, collecting motion information of the current mobile terminal; obtaining a corresponding relation between the motion information and position information; when the satellite positioning signal is too weak to provide the effective position information, obtaining the motion information of the current mobile terminal; and according to the position at which the mobile terminal is positioned and a possible moving path on a map, obtaining a motion track of the current mobile terminal. The mobile terminal has a simple structure and is convenient to operate. The mobile terminal and the positioning method can be used for the fields of satellite positioning, vehicle navigation, motion tracking and the like.
Description
Technical field
The present invention relates to technical field of mobile terminals, relate in particular to a kind of portable terminal and the localization method thereof that can under the weak fix signal, locate.
Background technology
Along with the continuous development of science and technology and improving constantly of human substance life horizontal, the use coverage rate of portable terminal has reached a quite broad scope.At present the mobile phone recoverable amount of China has surpassed 400,000,000 ones, and first generation analogue communication is superseded in last century Mo, current universal be second generation digital communication mobile phone and 3G (Third Generation) Moblie mobile phone (3G).Present most mobile phone also supports handwriting input, MP3, MP4 to play, take pictures and function such as shooting except basic functions such as clock, conversation and note, can be used for listening to the music, see a film, playing games, and also some mobile phone has the GPS navigation function.
Current global position system on the market all is to pass through receiving satellite positioning signals, determine the current device position, if satellite positioning signal is weak or when not having, as enter the tunnel or enter satellite positioning signal such as lane and receive relatively poor area, equipment can't be located, and become " blind area " of positioning function.
Summary of the invention
The purpose of this invention is to provide a kind of portable terminal and the localization method thereof that can under the weak fix signal, locate, in order to solve the deficiencies in the prior art.
For achieving the above object, the invention provides a kind of portable terminal that can locate under the weak fix signal, it comprises control module and the display screen that all links to each other with control module, loudspeaker, button, storage element, GPS locating module, acceleration transducer and gyroscope.
The present invention also provide a kind of can be at the localization method under the weak fix signal, it comprises:
Under the effectively available situation of satellite positioning signal, collect the movable information of current mobile terminal;
Movable information in a period of time is carried out statistical study, obtain the corresponding relation of movable information and positional information;
According to this corresponding relation, set up an estimation mode;
When satellite positioning signal weakens to no longer can provide effective positional information the time, obtain the movable information of current mobile terminal, draw motion state whether how degree change takes place or take place;
According to the correspondence relationship information that obtains before, draw the mobile status difference before of portable terminal;
Go up residing position of portable terminal and possible mobile route more according to the map, draw the movement locus of current mobile terminal.
Further, this localization method also comprises: under the effectively available situation of satellite positioning signal, constantly this estimation mode is upgraded and proofread and correct, to obtain the corresponding relation of accurate movement information and positional information more.
Further, described movable information comprises acceleration information or portable terminal heeling condition.
The present invention is owing to adopt technique scheme, can be a little less than satellite positioning signal or when not having, according to the positional information that obtains before, the sensing data and the map datum of portable terminal are integrated, by computing, obtain the positional information of current most possible estimation, be implemented in the positioning function under the satnav weak signal state.The present invention is simple in structure, and simple operation can be used for fields such as satnav, vehicle mounted guidance, motion tracking.
Description of drawings
For can clearer understanding purpose of the present invention, characteristics and advantage, below with reference to accompanying drawing preferred embodiment of the present invention is described in detail, wherein:
An embodiment synoptic diagram of the portable terminal that Fig. 1 can locate under the weak fix signal for the present invention;
Fig. 2 is the schematic flow sheet of portable terminal of the present invention localization method under the weak fix signal.
Embodiment
See also Fig. 1, the portable terminal that can under the weak fix signal, locate, it comprises control module 1 and the display screen 2 that all links to each other with control module 1, loudspeaker 3, button 4, storage element 5, GPS locating module 6, acceleration transducer 7 and gyroscope 8.
Please consult Fig. 2 simultaneously, the flow process of portable terminal localization method under the weak fix signal comprises:
Under the effectively available situation of satellite positioning signal, collect the movable information of current mobile terminal, comprise acceleration information or portable terminal heeling condition etc.;
Movable information in a period of time is carried out statistical study, obtain the corresponding relation of movable information and positional information;
According to this corresponding relation, set up an estimation mode;
Under the effectively available situation of satellite positioning signal, constantly this estimation mode is upgraded and proofread and correct, to obtain the corresponding relation of accurate movement information and positional information more;
When satellite positioning signal weakens to no longer can provide effective positional information the time, obtain the movable information of current mobile terminal, draw motion state whether how degree change takes place or take place;
According to the correspondence relationship information that obtains before, draw the mobile status difference before of portable terminal;
Go up residing position of portable terminal and possible mobile route more according to the map, draw the movement locus of current mobile terminal.
With an automobile is example, when portable terminal is on the automobile in travelling, under the effective situation of satellite positioning signal, obtain current change in location rule, as the state that gives it the gun, the acceleration information of motion sensor acquisition at this moment is toward vehicle forward direction individual acceleration to be arranged.When satellite positioning signal lost efficacy,, show that then automobile is still quickening with before acceleration if significant change does not take place the acceleration information of this motion sensor; If the acceleration information of motion sensor becomes 0, represent that then automobile becomes at the uniform velocity state.According to obtaining velocity information,, obtain the current present position of this automobile in conjunction with the map possible travel route of getting on the car.
