Abstract
The utility model discloses an implementing device of an infrared remote control function of a mobile phone, comprising a baseband chip, an acceleration sensor and an infrared remote control module, wherein the acceleration sensor is connected with the baseband chip of the mobile phone and is used for outputting the motion change information of the mobile phone in a three-dimensional space; the baseband chip of the mobile phone is used for receiving and processing the motion change information output by the acceleration sensor and sending encoded data to the infrared remote control module; and the infrared remote control module is used for receiving the encoded data of the baseband chip of the mobile phone and modulating and sending the data. By the acceleration sensor integrated in the mobile phone and provided with the infrared remote control function, the implementing device realizes infrared remote control to the household electrical appliances under the premise without the need of key-pressing operation, thus improving user experience.
Description
Technical field
The utility model relates to a kind of implement device of mobile phone infrared remote function, particularly relates to a kind of implement device that need not the mobile phone infrared remote function of button operation.
Background technology
Along with development of times, the kind of household electrical appliance is more and more, enriched people's spare-time cultural life largely, because every kind of household electrical appliance all have corresponding Infrared remote controller, so just need the frequent Infrared remote controller of changing to control corresponding household electrical appliance, brought inconvenience when enjoying life to people.In order to address the above problem, the mobile phone of function of infrared remote control has appearred much having in the market, because it has very friendly man machine operation interface, good self-learning function has been subjected to a lot of users' favor.
Yet, when existing this class mobile phone is opened at its function of infrared remote control, all be by with the mobile phone key operation map to the button operation of traditional infrared remote controller, and will launch by the infrared remote control module behind these operational order infrared codings, thereby control corresponding household electrical appliance.This just needs the user to understand which button on the mobile phone corresponding to infrared operation, and to remember its corresponding position, this brings very big inconvenience for some practical operation, the user who particularly gets used to place (for example lie on a bed evening and see TV) remote control home appliance at dim light for those, the very difficult position of judging respective keys.
Summary of the invention
At the deficiency of prior art, the purpose of this utility model is to provide a kind of implement device of mobile phone infrared remote function, and the user carries out under the prerequisite of button operation not needing, and just can carry out infrared remote control to household electrical appliance, thereby improve user experience.
The utility model comprises: baseband chip, acceleration transducer, infrared remote control module, and described acceleration transducer is connected with mobile phone base band chip, is used for exporting the information of mobile phone in the three dimensions motion change; Mobile phone base band chip is used to receive and handle the motion change information of acceleration transducer output, and the data after will encoding send to the infrared remote control module; The infrared remote control module is used to receive the data after mobile phone base band chip is encoded, and will launch after this data-modulated.
The utility model is by having the integrated acceleration transducer in mobile phone inside of function of infrared remote control, change by measuring the attitude of mobile phone in three dimensions, and different attitude changed be converted into corresponding infrared control instruction, thereby reached the purpose of control household electrical appliance.
Operation principle:
1, under the mobile phone infrared remote function opening, when certain variation took place the attitude of mobile phone, acceleration transducer required baseband chip to read the numerical value of mobile phone motion change in three dimensions of its measurement by the I2C interface by the mode of interrupting.
2, the digital signal of systems soft ware degree of will speed up transducer output is converted into the angle variation under the three dimensional space coordinate, thereby extrapolates the movement tendency of mobile phone.
3, being tilted to the left, being tilted to the right, turning forward, receding of mobile phone, corresponding respectively left and right, the upper and lower button of traditional infrared remote controller.
4, under the mobile phone infrared remote function opening, after mobile phone enters battery saving mode, close acceleration transducer automatically, withdraw from behind the battery saving mode and recover again.
Because the difference on the cell-phone function is more and more littler now, it is operational simple and practical that the user selects mobile phone often more to pay attention to.Particularly as the function of this class of infrared remote control, operation is simple more good more for the user.The utlity model has advantages such as simple in structure, easy to operate.

Embodiment
How further specify the utility model below in conjunction with accompanying drawing realizes:
As shown in Figure 1, form, comprise modules such as radio frequency, LCD, camera, touch-screen and power management in the mobile module by mobile module, infrared remote control module 3 and acceleration transducer 2; Infrared remote control module 3 is used to receive the infrared control instruction and will launches after its modulation; Acceleration transducer 2 links to each other by three GPIO with mobile phone base band chip 1, wherein two GPIO are as the SCL and the SDA of I2C bus, another one GPIO is as the external hardware interrupt pin, to realize operations such as the resetting of 1 pair of acceleration transducer 2 of mobile phone base band chip, setting, reading of data.The hardware and software resource consumption all seldom, can too much not increase the burden of original cell phone system.
As shown in Figure 2, when the mobile phone infrared remote function is opened, according to following steps:
Step S200: beginning.
Step S201: initialization acceleration transducer 2, configuration relevant register.
Step S202: configuring external hardware interrupts pin is high level triggering mode and opens interrupters.
Step S203: judge whether X, the Y in acceleration transducer 2 three dimensions, the acceleration change value on Z three direction of principal axis have triggered interruption, if down trigger is changeed step S204; Otherwise change step S203.
Step S204: read acceleration value on acceleration transducer X, Y, Z three direction of principal axis by the I2C bus.
Step S205: the acceleration value on three direction of principal axis is converted into the value in (1 ,+1) interval range, the angle that is translated on three direction of principal axis according to inverse cosine function changes then.
Step S206: the angle on three direction of principal axis of measuring with the last time changes and compares, thereby draws the movement tendency of mobile phone.
Step S207: the movement tendency of mobile phone is carried out infrared coding.
Step S208: the infrared control instruction after will encoding sends to infrared remote control module 3, and infrared remote control module 3 is launched after it is modulated.
Step S209: judge whether mobile phone enters battery saving mode, if mobile phone enters battery saving mode and then changes step S210; Otherwise, change step S203.
Step S210: finish.
