Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and embodiment.
As an embodiment, the present invention is useful on the Linux cell phone platform.Introduce earlier below in the present embodiment the vocabulary of using: GPS (Global Positioning System), global positioning system; NMEA (National Marine Electronics Association), GPS serial ports host-host protocol; UTC (Universal Time Coordinated), world unified time; Buffer, buffering area; GPRMC, GPGGA, GPGSV, GPGSA are four kinds of NMEA data formats.
In addition, in the present embodiment be with using De $GPRMC statement meaning and span:
< 1>UTC time: hhmmss.ss-(000000.00-235959.99); < 2>state, validity-A represent that effectively V representes invalid; < 3>latitude form: ddmm.mmmm-(0000.00000-8959.9999); < 4>southern hemisphere and northern hemisphere-N north latitude, the S south latitude; < 5>longitude format: dddmm.mmmm-(00000.0000-17959.9999); < 6>thing hemisphere-E representes east longitude, and W representes west longitude; < 7>ground speed-(000.00-999.999); < 8>velocity attitude-(000.00-359.99); < 9>date format, month day year-(010100-123199); < 10>magnetic declination, unit: degree-(00.00-99.99); < ll>magnetic declination direction-E representes east, and W representes the west; < 12>pattern indication and verification and-A=autonomous positioning, the D=difference, the E=estimation, the N=data are invalid.
Referring to Fig. 1, Fig. 1 has shown that a kind of the location according to GPS is provided with mobile phone time method 100 automatically, may further comprise the steps:
101, the GPS information receiving module is set on said mobile phone;
102, receive gps data and resolve its positional information that comprises and temporal information through said GPS information receiving module; Said positional information and temporal information comprise longitude information, UTC temporal information, date information.
103, through pre-defined rule, the local standard time of calculating said mobile phone according to the said positional information that parses and temporal information.Specifically, if judge and when said longitude information is east longitude the UTC time and the time zone value addition that obtain to be obtained local standard time,, then UTC time of acquisition and time zone value are subtracted each other and obtain local standard time if when the said longitude information of judgement is west longitude.
104, call the said standard time that calculates and it is set to the time of said mobile phone.
Referring to Fig. 2, Fig. 2 has shown that the present invention receives the flow chart of GPS information data, and the GPS chip among the figure is the GPS information receiving module, and the NMEA data are gps data.
At first carry out the hardware abstraction layer initialization, promptly open serial ports and newly-built daily record output directory; Next carries out the GPS initialization, comprises successively: the driving initialization of GPS chip, and open and send a series of initialization commands to the A-GPS chip, prepare the receiving satellite certificate, device start pattern (cold start-up, warm start, the warm startup) is set, open navigation mode; Receive the initialization of NMEA data again, promptly open the NMEA data of the main termination receiving satellite of pseudo-terminal (virtual terminal); Last close port is accomplished the reception of data.
Under the situation of Linux as cell phone system, utilize pseudo terminal device to be mapped to the form of file, carry out interprocess communication through the mode of pseudo-terminal, read locating information and realize through the form that reads file.In addition; The NMEA data have four kinds of form: GPRMC, GPGGA, GPGSV, GPGSA; Wherein use for the ordinary GPS Kinematic Positioning; The GPRMC statement meets the demands fully, comprises fields such as longitude and latitude, speed, time and magnetic declination in the GPRMC statement, and these data are that the navigator fix application provides sufficient information.The present invention is exactly the local standard time that goes out mobile phone through the analytical Calculation to these data.
Referring to Fig. 3, Fig. 3 has shown the flow chart that reads parsing GPS information data and the mobile phone time is set:
S1, open the GPS navigation system, the GPS chip begins to receive satellite fix information, and the NMEA data are outputed to pseudo terminal device through serial ports;
S2, click keys or touch-screen judge that message event is for being provided with the mobile phone time;
S3, read the NMEA data from pseudo-terminal;
S4, parsing NMEA data, specifically as follows:
The NMEA data are the GPRMC formatted data, and it is divided into 12 field: $GPRMC, < 1 >, < 2 >, < 3 >, < 4 >, < 5 >, < 6 >, < 7 >, < 8 >, < 9 >, < 10 >, < ll >, < 12 >.
Whether effective, if effectively, (E representes east longitude then to read east longitude or west longitude information from < 6>field according to < 2>field if reading the GPRMC that receives; W representes west longitude), parsing deposits buffer (buffering area) ， $GPRMC statement meaning in and has done narration above the span.
According to the NMEA data that read, resolve year, the moon, day information of GPRMC statement < 9>field, deposit the information that obtains in buffer respectively;
According to the NMEA data that read, resolve the longitude information of GPRMC statement < 5>field, obtain longitude and deposit buffer in;
According to the NMEA data that read, resolve the UTC time of GPRMC statement < 1>field, obtain temporal information and with the time, branch, second deposit buffer respectively in;
If longitude information is east longitude, with the UTC time that obtains add 1 obtain local standard time one hour value (this moment, the time zone value was 1); If otherwise west longitude, then with the UTC time that obtains subtract 1 obtain local standard time one hour value, finally obtain local time information.
In the above resolving; The time zone value can be provided with through the user; Also can read environmental variance TZ through the zoneinfo system file of Linux and obtain time-zone information, function time () is used for obtaining the described UTC time, and localtime () is used for obtaining local zone time.
The upper layer software (applications) of S5, cell phone system reads and is stored among the buffer corresponding year, month, day and time, calls explicit function and shows and be provided with.
As on the other hand, the present invention also provides a kind of and according to the GPS location mobile phone of time is set automatically, comprising:
The GPS information receiving module is in order to receive the GPS information data;
Parsing module connects said GPS information receiving module, in order to resolve positional information and the temporal information in the said GPS information data.As an embodiment, positional information and temporal information in the gps data that said parsing module is resolved comprise longitude information, UTC temporal information, date information.
Computing module connects said parsing module, through pre-defined rule and local standard time of calculating said mobile phone according to the said positional information that parses and temporal information; As an embodiment, the pre-defined rule in the said computing module is: when said longitude information is east longitude, the UTC time and the time zone value addition that obtain are obtained local standard time; When said longitude information is west longitude, then the UTC time that obtains and time zone value is subtracted each other and obtain local standard time.
Module is set, connects said computing module, call the said standard time that calculates and it is set to the time of said mobile phone.
It is to be noted; A kind of mobile phone that the time is set according to GPS location automatically of the present invention a kind ofly locatees according to GPS that the mobile phone time method is set automatically is identical and similar with of the present invention on principle and embodiment, so its repeating part repeats no more.
