Abstract

The invention discloses a system for combined use of an induction key code and a remote control code. The system comprises an induction key board, a remote control board and a switching circuit; when no induction key is pressed or the keystroke of an induction key is completed, the induction key board outputs a low level control signal and a low level induction key signal; when an induction key is pressed, the induction key board outputs an induction key signal and a high level control signal; the remote control board outputs a remote control code signal; when the induction key board outputs a low level control signal and a low level induction key signal, the switching circuit stops the control signal and the induction key signal from being output, and meanwhile the remote control code signal output by the remote control board is output after being shaped; and when the induction key board outputs a high level control signal, the switching circuit stops the remote control code signal from being output, and meanwhile, the induction key signal is output after being subjected to phase reversal. The induction key signal provided by the invention adopts a special remote control code, and can be subjected to unified processing after being used in combination with the remote control code signal, so that both wire connection and cost are reduced.

Description

technical field [0001] The invention relates to the technical field of television manufacturing, in particular to a multiplexing system of induction key codes and remote control codes. Background technique [0002] The current electronic equipment generally handles the sensor buttons and remote control signals separately, such as figure 1 As shown, the remote control signal sent by the remote control board is a serial coded signal, which is decoded after being received by the processing part; while the sensory key signal sent by the sensory keypad is a non-coded signal, which is received by the processing part for A / D conversion or scanning detection. [0003] Due to the different forms of the two signals, the remote control signal and the sensor key signal are processed separately, which increases the processing complexity and the key output connection cost. Contents of the invention [0004] In view of the above analysis, the purpose of the present invention is to prov...
