Mode to the mobile phone screen locking roughly includes at present: slip release, unlock password and gesture release etc., and the slip release does not have privacy, and the people around the gesture release is easy to know, and unlock password relatively lacks new meaning; How providing a kind of for this reason and not only have interesting but also have private release mode, is the problem that present mobile phone scheme merchant is faced.
Summary of the invention
For this reason, the object of the present invention is to provide a kind of mobile phone system for unlocking and method, to solve the problem that present mobile phone screen release lacks new meaning and do not have privacy based on geomagnetic sensor.
For realizing above-mentioned purpose, the present invention mainly adopts following technical scheme:
A kind of mobile phone system for unlocking based on geomagnetic sensor; Comprise mobile phone body; Be installed in mobile phone CPU, microprocessor, geomagnetic sensor, release control module and pattern matching module in the mobile phone body, said geomagnetic sensor is connected with microprocessor, and said microprocessor is connected with mobile phone CPU; Mobile phone CPU is connected with the pattern matching module, and this pattern matching module is connected with display screen through the release control module.
One data storage also is installed in the wherein said mobile phone body, stores the mobile phone standard in this data storage and move orientation angles information.
It is single orientation angles information or combination orientation angles information that wherein said standard moves orientation angles information.
In addition, the present invention also provides a kind of mobile phone unlock method based on geomagnetic sensor, comprising step:
A, rotation mobile phone make mobile phone orientation angles generation conversion, and this variation numerical value of record, send to microprocessor;
B, microprocessor send to mobile phone CPU with the mobile phone bearing variation value that obtains, and mobile phone CPU analyzes it, sends to the pattern matching module;
After C, pattern matching module coupling were passed through, control release control module was to the display screen release.
Wherein steps A specifically comprises:
When the mobile phone standard moves orientation angles information is single orientation angles information, and mobile phone is when being in the screen locking state, stop after rotating mobile phone, and the residing orientation angles information of record current phone, and correspondence sends to microprocessor.
Wherein steps A specifically comprises:
When moving orientation angles information, the mobile phone standard is combination orientation angles information; And when mobile phone is in the screen locking state; Stop after rotating mobile phone, the residing orientation angles information of record current phone is repeatedly rotated mobile phone afterwards again; Residing orientation angles information when the record mobile phone is static, and correspondence sends to microprocessor.
Wherein step B specifically comprises:
Microprocessor sends to mobile phone CPU with the mobile phone bearing variation value that obtains, and mobile phone CPU analyzes it, and the standard in the data storage transferred simultaneously moves orientation angles information and together sends to the pattern matching module, and the two matees the pattern matching module to it.
Wherein step C specifically comprises:
After the pattern matching module was passed through the mobile phone rotational angle information obtained and mobile orientation angles information matches, control release control module was to the display screen release, and coupling is not passed through, and mobile phone display screen keeps locking.
The present invention obtains mobile phone present located orientation angles information through being arranged on geomagnetic sensor in the mobile phone, and in mobile phone, sets the needed orientation angles information of release in advance; When needing release, rotate mobile phone, its orientation angles is changed; And with the angle and predefined the comparing that change, if consistent, then the release requirement is satisfied in expression; Otherwise, then can not release.Compared with prior art, the present invention has only after the input of mobile phone rotational angle is correct, could therefore the mobile phone screen release be had advantages such as interest is strong, privacy is good.

Embodiment
For setting forth thought of the present invention and purpose, will combine accompanying drawing and specific embodiment that the present invention is done further explanation below.
See also shown in Figure 1ly, Fig. 1 is a system principle diagram of the present invention.The present invention is to provide a kind of mobile phone system for unlocking based on geomagnetic sensor; Comprise mobile phone body; Be installed in mobile phone CPU, microprocessor, geomagnetic sensor, release control module and pattern matching module in the mobile phone body, said geomagnetic sensor is connected with microprocessor, and said microprocessor is connected with mobile phone CPU; Mobile phone CPU is connected with the pattern matching module, and this pattern matching module is connected with display screen through the release control module; One data storage also is installed in the wherein said mobile phone body, stores the mobile phone standard in this data storage and move orientation angles information, it is single orientation angles information or combination orientation angles information that said standard moves orientation angles information.
Geomagnetic sensor can be responded to the current angle information of mobile phone according to the mobile phone current location information; And the digital compass through correspondence shows on the handset displays screen, be in 86 ° in east as mobile phone is current, and the unlock command that the user sets is 190 ° in eastern 86 °+south; Have only this moment when the user is first mobile phone is turned to 86 ° in east; Static setting-up time, when turning to southern 190 ° afterwards again, mobile phone screen is just understood release.
Certainly, the user can also be provided with more complicated unlock command, and its sequencing is carried out requirement, turns to 86 ° in east earlier like needs, and then turns to 30 ° in north, then turns to 50 ° in south again, if in proper order not right, could not release; In addition, the user also can be provided with more simple unlock command, such as only need mobile phone being turned to 86 ° in east, can produce release, and concrete here unlock command and user preestablish and store relevantly, can set according to the hobby of oneself.
After setting completion; In the time of need be to the screen release; The user just need carry out release according to the step of setting, and judges specifically whether release is successful, and whether the mobile phone rotational angle information of then obtaining through the comparison geomagnetic sensor is consistent with the release angle information of standard storage; If consistent, then can realize the screen release of mobile phone.
When the user need be to the mobile phone screen release, then need mobile phone be turned an angle according to setting means got final product, if operating mistake; The pattern matching module then can not be mated and passed through; Can not make the release control module to the display screen release, if coupling is passed through, then correspondence can release; The mode of this operation has great interest and privacy, and is not easy to be found by the people.
