Code matching method and system of wireless remote control device

Abstract

The invention provides a code matching method and system of a wireless remote control device. The code matching method comprises the following steps: generating a radio frequency communication mark in a radio frequency transmission module by utilizing NFC (Noise Feedback Coding) near field communication; storing the radio frequency communication mark in an NFC label; reading the radio frequency communication mark stored in the NFC label by an NFC reading unit arranged in the radio frequency transmission module; and sending the read radio frequency communication mark to a radio frequency identification control module so that the radio frequency identification control module and the radio frequency transmission module perform communication by taking the radio frequency communication mark as an only communication mark, so as to finish a code matching process. According to the method and the system, the NFC near field communication is used for finishing the code matching process and the interferences on signals with the same frequencies in the environment are avoided, so that the code matching effect can be obtained and the convenience for carrying out code matching on the remote control device by a user is provided.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a code matching method and system for a wireless remote control device. Background technique [0002] The TV set is generally controlled by a remote controller, and a common remote controller realizes its remote control function using a wireless infrared transmitter and a wireless infrared receiver. Along with the intellectualization of TV sets, TV sets have more and more functions, and the application of radio frequency technology in TV remote control technology is also more and more common. [0003] At present, 2.4G code pairing technology is often used in radio frequency technology. Take the most common TV remote control device as an example, such as figure 1 As shown, the remote control dongle (software dog) and the remote control are uniquely paired through a randomly generated 32bit data as a communication symbol. The code pairing process is as follows: [0004] 1....

AI Technical Summary

Problems solved by technology

[0007] Since the above-mentioned 2.4G code pairing process, including the 2.4G code pairing request and the return confirmation of the 32bit flag, are all through 2.4G communication, it is very easy to be interfered by other wireless signals in the environment, causing the code pairing to fail, and the user bad experience
