Infrared remote control method and system

Abstract

The invention provides an infrared remote control method. The infrared remote control method comprises the following steps that S1, a remote control device sends control information to a control center; S2, the control center receives the control information, converts the control information into infrared coded information and sends the infrared coded information to a forwarding device; S3, the forwarding device receives the infrared coded information, extracts an infrared code command and sends the infrared code command to a controlled device; and S4, the controlled device receives and executes the infrared code command. According to the invention, low-power protocols and the infrared forwarding device are combined, and the control center is employed to overcome the problem of incapable of matching with household electrical appliances due to insufficient computing power of the forwarding device.

Description

technical field [0001] The invention belongs to the technical field of remote control, and in particular relates to an infrared remote control method and system. Background technique [0002] At present, people's material and cultural living standards are improving day by day, and various household appliances have entered thousands of households. Among them, most household appliances such as TV, DVD, set-top boxes, air conditioners, etc. have their own remote controls. People often look everywhere for their corresponding remote controllers in order to control a certain electrical appliance, which brings a lot of inconvenience to people's lives. [0003] In the prior art, a universal remote controller is designed, which can remotely control multiple household appliances, and solves the problem of inconvenient use of multiple remote controllers. [0004] However, the remote control controls household appliances through infrared, and the remote control operation must be realiz...

Problems solved by technology

[0002] At present, people's material and cultural living standards are improving day by day, and various household appliances have entered thousands of households. Among them, most household appliances such as TV, DVD, set-top boxes, air conditioners, etc. have their own remote controls. People often look for its corresponding remote control everywhere in order to control a certain electrical appliance, which brings a lot of inconvenience to people's life.

[0003] In the prior art, a universal remote controller is designed, which can remotely control multiple household appliances, and solves the problem of inconvenient use of multiple remote controllers

[0004] However, the remote control controls household appliances through infrared, and the remote control operation must be realized within the range that the remote control receiver can receive. The existing infrared forwarding gateway technology is limited by the transmission distance of infrared signals, such as partition walls, which cannot be transmitted. has very big limitations
