In said method, before the radio data system signal that receives the radio station, also comprise:
The signal in the radio station that the terminal traversal current region of described subsidiary FM chip is all is sought the radio station with described radio data system signal.
In said method, go out temporal information from described RDS signal resolution before, also comprise:
Judge that the described RDS signal that receives does not comprise temporal information, if from described RDS signal, parse temporal information; Otherwise, receive the RDS signal in radio station again.
In said method, draw after described RDS signal comprises temporal information in judgement, also comprise:
Check the error correcting code that described RDS signal carries,, judge whether described RDS signal makes mistakes in transmission course, if receive the RDS signal in radio station again according to check result; Otherwise, from described RDS signal, parse temporal information.
The terminal of the present invention automatic lock in time comprises that FM chip, resolution unit and time is provided with the unit, wherein,
Described FM chip is used to receive the RDS signal in radio station;
Described resolution unit is used for parsing temporal information from described RDS signal;
The described time is provided with the unit, is used for according to described temporal information the system time of described terminal being set.
In above-mentioned terminal, also comprise: query unit, described query unit are used to judge that the described RDS signal that receives does not comprise temporal information, if trigger described resolution unit; Otherwise, trigger described FM chip.
In above-mentioned terminal, described query unit also is used for, and draws after described RDS signal comprises temporal information in judgement, check the error correcting code that described RDS signal carries,, judge whether described RDS signal makes mistakes in transmission course according to check result, if trigger described FM chip; Otherwise, trigger described resolution unit.
In above-mentioned terminal, described frequency modulation chip also is used for, and the signal in the radio station that the traversal current region is all is sought the radio station with described radio data system signal.
Compared with prior art, the invention provides method and the terminal of a kind of automatic lock in time, utilize the entrained temporal information of RDS signal of FM radio station, the system time of terminal is set, not only comparatively accurately with in time, and not needing user's manual operations, the terminal automatic update system time, the convenient hommization that has again seems.In addition, do not need access web server, saved user's spending, reduced user's cost.
After the detailed description of reading embodiment of the present invention in conjunction with the accompanying drawings, it is clearer that characteristics of the present invention and advantage will become.

Embodiment
Describe below in conjunction with the method and the terminal of accompanying drawing the present invention automatic lock in time.This terminal is the terminal of subsidiary FM chip, comprises the portable terminal of subsidiary FM chip, such as the mobile phone of subsidiary FM chip.
See also Fig. 1, it is the present invention's method flow schematic diagram of automatic lock in time.
The method of the present invention automatic lock in time may further comprise the steps:
The terminal of step S1, subsidiary FM chip receives the RDS signal in radio station;
Step S2, from described RDS signal, parse temporal information;
Step S3, according to described temporal information, the system time of described terminal is set.
See also Fig. 2, it is the present invention's method idiographic flow schematic diagram of automatic lock in time.
The method of the present invention automatic lock in time specifically may further comprise the steps:
Step 11, search have the FM radio station of RDS signal.Terminal provides a display interface, and the function choosing-item that demonstration can be selected for the user is such as the function choosing-item of RDS function real-time lock in time of utilizing FM.The user selects this option, and terminal is opened built-in FM chip.Terminal begins to travel through the signal in all radio station of current region by the FM chip, seeks the FM radio station with RDS signal.After FM chip traversal, wait for a Preset Time, such as 40ms, then,, represent the FM chip to receive that (RDSR) from the RDS packet in current frequency radio station is changed to 1, shows that then current FM radio station has the RDS signal if in the FM chip.
Further, in the above-described embodiments, step 13 also comprises: check the error correcting code that the RDS packet carries,, judge whether the RDS signal makes mistakes in transmission course according to check result, if, execution in step 12, otherwise, execution in step 14.Draw the RDS bag for behind the temporal information bag in judgement, check the error correcting code that the RDS packet carries, according to check result, whether judgement makes mistakes in data transmission procedure.Number is then discarded current RDS packet greater than 0 if make mistakes, and execution in step 12.If do not make mistakes, then execution in step 14.
