System and method for learning remote controller

Abstract

The invention discloses a system for learning a remote controller, which comprises a control module, a signal receiving unit, a signal analyzing unit, a signal recognizing unit, a switching signal generating unit and a data writing unit, wherein the control module is used for starting or stopping the learning state of a learning module; the signal receiving unit is used for receiving signals emitted by the other remote controller; the signal analyzing unit is used for converting the received signals into binary logic data code; the signal recognizing unit is used for recognizing whether the binary logic data code is RC5 code or not, and the binary logic data code is directly transmitted to the data writing unit if the binary logic data code is not the RC5 code; the switching signal generating unit generates switching data and transmits the switching data to the data writing unit if the binary logic data code is RC5 code; and the data writing unit is used for writing the generated switching data or the binary logic data code into a memory module. The invention also discloses a method for learning a remote controller, can be used for learning the RC5 code and two functions of one same key, thereby improving the adaptability of the learning remote controller.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a remote controller learning system and method. Background technique [0002] There are many kinds of remote control codes on the market at present, but the commonly used infrared remote control codes are mainly the coding standards of NEC and Philips, and the others are variants of these two types. A frame of the RC-5 coding standard adopted by Philips consists of the following parts: 1) the start code part is 2 logic 1s; 2) the control code part, 1 bit; 3) the system code part, 5 bits; 4) the instruction Code part, 6 digits. When transmitting continuously, the repeating waveform is the same as the first transmitting waveform. The control code bit changes alternately in the front and back key presses again. 0 and 1 codes are transmitted using bi-phase encoding transmission technology. [0003] Each button of a common remote control has only one function in a certain mode...

Problems solved by technology

But if you learn a remote control with a format similar to RC5, you will only be able to learn one function of the same button, and you will not be able to learn another grou
