Wherein also include a data storage, this data storage is connected with 3-axis acceleration sensor through microprocessor.
Store the original displacement data of mobile phone body in the wherein said data storage.
In addition, the present invention also provides a kind of method of mobile phone upset screen locking, comprises step:
A, 3-axis acceleration sensor obtain X, Y, the Z-direction displacement of mobile phone body, and send to microprocessor;
B, microprocessor call the original displacement data of mobile phone body in the data storage; Compare with the mobile phone body X that obtains, Y, Z-direction displacement; If X, Y direction displacement are 0; And the Z-direction displacement is negative by just becoming, and judges that then mobile phone is a face down by the upset that faces up;
C, microprocessor produce the screen locking signal and give mobile phone CPU, and mobile phone CPU control screen locking control module is carried out screen locking to display screen.
Wherein include before the steps A:
Microprocessor obtains the original displacement data under the current inactive state of mobile phone body through 3-axis acceleration sensor, and it is stored in the data storage.
Wherein steps A comprises: the upset mobile phone body, 3-axis acceleration sensor obtains mobile phone body at X, Y, Z-direction displacement according to the upset amplitude correspondence of mobile phone body.
The present invention quantizes the overturn action of mobile phone of user through the 3-axis acceleration sensor that is arranged in the mobile phone; Form corresponding change in displacement; And with mobile phone in original displacement compare, judge whether mobile phone upset through comparative result, if be turned to the screen locking position; Then correspondence is sent the screen locking signal, and CPU locks display screen by mobile phone.Compared with prior art, the present invention has advantage simple to operate, easy to use, efficiently solves present mobile phone screen locking mode inconvenient operation, and the problem that compares power consumption.

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.
The present invention is to provide a kind of system and method for mobile phone upset screen locking; Through being arranged on the inner 3-axis acceleration sensor of mobile phone, the displacement that mobile phone is produced detects, and the corresponding displacement data of corresponding generation; Displacement through this displacement data and original inactive state compares; Judge whether mobile phone has carried out rotary movement, if then corresponding generation screen locking signal locks display screen.
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 system of mobile phone upset screen locking; Comprise mobile phone body; Be installed in mobile phone CPU, microprocessor, 3-axis acceleration sensor, screen locking control module, data storage and display screen in the mobile phone body; Said 3-axis acceleration sensor is connected with microprocessor, and said microprocessor is connected with mobile phone CPU, and mobile phone CPU is connected with display screen through the screen locking control module; Said data storage is connected with 3-axis acceleration sensor through microprocessor, and stores the original displacement data of mobile phone body in this data storage.
When mobile phone body is in the home position; This moment, microprocessor can judge that through 3-axis acceleration sensor mobile phone body remains static; The coordinate of setting mobile phone screen central point this moment is (x y z); In data storage, the expression mobile phone is in the home position that does not produce under the mobile status with this coordinate points corresponding stored for corresponding microprocessor.
When rotating mobile phone, when it was overturn, the coordinate points at mobile phone screen center can change on the mobile phone body at this moment; Owing to be the upset behavior; Therefore basic not variation on the horizontal plane, the coordinate on the vertical plane then is inverted, and changes to negative Z axle by positive Z axle; Represent the mobile phone completion of having overturn this moment, and screen is by becoming down up.
After the mobile phone screen upset, corresponding microprocessor can produce the screen locking signal and give mobile phone CPU, and after mobile phone CPU received the screen locking signal, control screen locking control module locked display screen, realizes the purpose of mobile phone upset screen locking.
See also shown in Figure 2ly, Fig. 2 is a workflow diagram of the present invention.The present invention also provides a kind of method of mobile phone upset screen locking, comprises step:
A, 3-axis acceleration sensor obtain X, Y, the Z-direction displacement of mobile phone body, and send to microprocessor;
