Description

A learning method for a learning remote control

technical field

The invention relates to the field of electronics, in particular to a learning method for a learning remote controller.

Background technique

The principle of traditional ordinary infrared remote control to control home appliances is that each key of the remote control corresponds to a code, and each code corresponds to a series of modulated infrared pulse signals. After receiving the infrared pulse signals, the household appliances demodulate and decode to obtain This code, the value of the code indicates that the user presses the button corresponding to the code to enable functions such as switching the power supply, adjusting the volume, changing channels, etc., to achieve the purpose of remote control.

With the increase of household appliances, more and more people use learning remote control. The advantage of learning remote control is that it can replace the ordinary remote control of all household appliances in the home. Only one learning type remote control is needed. The remote control can complete the control of all home appliances. When a user buys a learning remote control home, the first thing to do is to learn all the common remote controls one by one, and then learn each common remote control key by key. A common learning method is: align the infrared emitting tube of the ordinary remote control with the infrared receiving tube of the learning remote control, press a button, and emit an infrared signal, enter the code sampling circuit of the learning remote control, and the code sampling circuit acquires Get the code corresponding to the button, and then save it in the internal memory of the learning remote control. This is a button learning process. Assume that there are 4 common remote controls at home, and each common remote control has an average of 20 buttons, which means that the learning process of 4 common remote controls must be repeated 80 times, which is very cumbersome and easy for users. error.
