Abstract
The invention discloses a mobile phone intelligent play method by using a mobile phone intelligent player system. The intelligent player system and the method of the mobile phone comprise the following steps: step A, a support on the rear cover of the mobile phone is opened so that a magnet is away from a Hall sensor; step B, the Hall sensor is free from the induction of a magnetic field and correspondingly outputs a high electric level to a microprocessor; step C, a central processing unit CPU generates a high-electric-level-triggered interrupt signal according to the high electric level signal, judges that the support is in an opened state, and control a player to play. According to the intelligent player system and the method of the mobile phone, the effect, on the Hall sensor, of the magnetic field of the magnet is utilized, when the support is opened, the Hall sensor correspondingly generates the high electric level and enables the CPU to generate high-electric-level-triggered interrupt in a corresponding mode, so that the player is controlled to be turned on automatically. According to the intelligent player system and the method of the mobile phone, automatic turn-on of player are achieved through the opening of the support, operation and use of a user are greatly facilitated, and the problem that operation procedures of a mobile phone player are complex currently is solved.

Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to shown in Fig. 1, Fig. 1 is system principle diagram of the present invention.The present invention is to provide a kind of handset intelligent playing system, be mainly used in the problem solving current mobile phone player operation program complexity.
Wherein native system includes the Hall element and support that are arranged on mobile phone back, described support is provided with the magnet corresponding with Hall element position, described Hall element comprises Hall element, amplifier, Schmidt circuit and open collector output triode, this Hall element is connected with CPU by microprocessor, and CPU is connected with player and memory.
Wherein Hall element magnet away from time, open collector output triode ends, and exports high level, and CPU produces high level triggered interrupts, and correspondence is opened player and play; Hall element magnet near time, magnetic fields produces Hall voltage when Hall element, and amplify through amplifier in Hall element and make triode ON output low level after Schmidt circuit, CPU produces low level triggered interrupts, correspondingly closes broadcasting.
When support income mobile phone battery cover, magnet on support is close to the Hall element on mobile phone battery cover, a small Hall voltage is produced when magnetic fields is in Hall element, amplify through amplifier in Hall element and make triode ON output low level after Schmidt circuit, a GPIO (chip pin) on cell phone mainboard CPU is connected with Hall element, the interruption that GPIO upper generation low level triggers, now system gets support and takes in back cover, and system enters holding state automatically; When user opens support under standby status of mobile phone, magnet on support is separated with the Hall element on mobile phone battery cover, Hall element is not by magnetic field induction, triode cut-off in HALL circuit, export as high level, the GPIO of cell phone mainboard CPU produces the interruption that high level triggers, system gets support and has opened, system enters operating state from holding state immediately, and automatically opens video player program.
Be more than the explanation to handset intelligent playing system of the present invention, be further described below in conjunction with 2 pairs, accompanying drawing cell phone intelligent player method of the present invention.
Shown in Figure 2, Fig. 2 is operation principle flow chart of the present invention.Present invention also offers a kind of cell phone intelligent player method, it is as follows that it specifically comprises step:
A, the support opened on cell phone rear cover, make magnet away from Hall element;
B, Hall element be not by magnetic field induction, and the corresponding high level that exports is to microprocessor;
Hall element is not by magnetic field induction, and open collector output triode ends, and exports high level, and the corresponding high level that exports is to microprocessor.
C, CPU produce high level triggered interrupts signal according to above-mentioned high level signal, judge that support is in open mode, and control player and play.
Support on D, closing hand phone bonnet, makes magnet near Hall element, and Hall element is by magnetic field induction, corresponding output low level is to microprocessor, CPU produces low level triggered interrupts signal according to above-mentioned low level signal, judges that support is in closed condition, closes player.
The present invention can simplify the flow process that mobile phone plays and cuts out vision operation, a few step operations needed before are become the operation that opens and closes mobile phone battery cover upper bracket, making it front cumbersome operation has become simply, and in addition, the support opened can play the effect of supporting mobile phone traverse.
