Multifunctional universal remote control system based on mobile phone platform

The invention provides a multifunctional universal remote control system based on a mobile phone platform. The multifunctional universal remote control system based on the mobile phone platform comprises the mobile phone platform and a signal conversion module, wherein the mobile phone platform monitors instruction information of users, converts the instruction information into American standard code for information interchange (ASCII) code control commands according to a mapping table and then sends the ASCII code control commands to the signal conversion module, the signal conversion module receives the ASCII code control commands sent by the mobile phone platform and transmits the ASCII code control commands to a control single chip microcomputer, the control single chip microcomputer finds infrared signal binary codes corresponding to the ASCII code control commands according to the mapping table and outputs the infrared signal binary codes to an infrared communication module, and the infrared communication module sends the input signals in an infrared light signal form and realizes the household appliance control. The multifunctional universal remote control system has the advantages that the household appliance remote control function can be added to a mobile phone without changing hardware circuits of the household appliances and the mobile phone, the operation capability and good interaction performance of the mobile phone are sufficiently utilized, and the infrared control on the household appliances is realized through the voice identification technology or through mobile phone press keys.
