Title:
INFRARED PROTOCOL-BASED INFRARED CODE TRANSMISSION CIRCUIT, CHIP, REMOTE CONTROL DEVICE AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/105069
Kind Code:
A1
Abstract:
Provided are an infrared protocol-based infrared code transmitting circuit, a chip, a remote control device and an air conditioner. The infrared code transmitting circuit comprises: a carrier wave duration control module (71); a processing module (72) that is used to configure the carrier wave duration control module (71) according to a phase type of a to-be-transmitted infrared code in an infrared protocol, so that the carrier duration control module (71) generates an enable signal; a carrier generation module (73) that is used to generate a PWM type carrier signal according to a phase type of the to-be-transmitted infrared code in the infrared protocol, carry out logical operation on the PWM type carrier signal and the enable signal to generate and transmit the to-be-transmitted infrared code. Therefore, transmission of the infrared code can be completed by the infrared code transmitting circuit, and the processing module (72) can enter a sleep state during the transmission process, thereby reducing power consumption and reducing the programming difficulty of the software.
