The Design And Implementation Of Multi-function Rf Remote Control For Smart Tv

With the boom of intelligent terminal equipment and "triple play" continues to advance,smart TV has full access to the era of networked,intelligent,high definition, gradually changing the habit of watching TV.Smart TV possess operating system,can realize the third-party application installation and operation,can finish multimedia businessas a mobile handheld device or personal computer,can also supports web browsing and body feeling game,etc.,human-computer interaction give users extreme personalized experience.To meet the demand of searching 、 browsing and game controling and other human-computer interactionbetter,Smart TVshould be on the basis of ordinary remote control function,increase the voice recognition,touch control,body feeling control,air mouse,and other functions.On the basis of the traditional remote control,around intelligent TV man-machine interaction experience,this topic design a new multifunctional using 2.4G wireless RF remote control.This multi-functional RF remote control technology include the main control module,keys module,power module,and other function modules,key modules connected to the main control processor and other function modules including RF and voice transmission module,the gyroscope module and the gravitational acceleration sensor module,other functional modules respectively connected to the main control processor of intelligent remote control.Among them,the main control processor and each module is provided power by the power supply module,which can be composed ofbooster chip and low dropout linear regulators,to provide the power for the entire system;Main control processor for sending the data processing module,and controlling all modules,need to choose single chip microcomputer whichcontain rich I/O resources and A/D interfaces;RF and voice transmission module is used to communication with the television according to the main control processor,byvoice transmission 2.4G RF modules,can complete speech transmission and RF transmition and reception.In terms of hardware design,according to the requirements of the overall functionality of a multi-function remote control,completing a main control chip selection is the first thing,and determine all the option form a complete set of components,and then complete the hardware design of a complete set of solutions,including the design of power management,voice module design,the touch module design and so on.In the aspect of software design,the multifunctional RF remote control software includes two parts,the receiver and transmitter remote control.The receiver mainly includes audio parts,the RF communication software with remote control transmitter,and the software of the USB interface.Remote control transmitter includes several softwares of main function modules,and power consumption management,low voltage test,etc.Finally,multi-function RF remote control prototype is completeda full range of testing and verification,including the realization of each function,and the performance and reliability of the prototype verification,finally it can meet the design expectations,can be batch production.
