Abstract

The invention discloses a control signal processing method, system and device. The method comprises: a waveform signal inputted through an audio input interface is received; according to a peak valueof the waveform signal, whether key code information is carried by the waveform signal is determined; if so, the waveform signal is decoded to obtain a key code instruction. With a high-efficiency andenergy-saving method, an intelligent terminal like a mobile phone or a tablet personal computer can obtain key code information of an external device like a tool panel accurately, so that a technicalproblem that key code information can not be obtained accurately is solved.

Description

technical field [0001] The present invention relates to the field of information processing, in particular to a method, system and device for processing control signals. Background technique [0002] In the prior art, many controllers (for example, toy panels) can send control signals to receivers or terminals, and the control signals can include key code information (ie, key operation information), and the terminal receives the control signals sent by the controller, The key code information in the control signal can be displayed, but there is little interaction between the controller and the smart terminal (mobile phone, tablet, etc.). In the existing cases, the system is also very complicated and consumes a lot of power. [0003] Therefore, it is an urgent problem to design a low-cost, low-power interactive system between the controller and the intelligent terminal. [0004] For the above-mentioned problem that it is impossible to accurately determine whether there is ke...
