Infrared repeat code learning method and infrared remote control system applied to Internet of Things

Abstract

The invention discloses an infrared repeat code learning method and an infrared remote control system applied to the Internet of Things. The method comprises the following steps: determining an extraction length according to the total byte length of an infrared code sent by an infrared remote controller; forward extracting to-be-matched data from the end of the last pulse signal of the infrared code according to the extraction length; forwards matching the to-be-matched data for multiple times; when the continuous matching success frequency reaches a preset frequency, judging that the to-be-matched data is a repeated code. Therefore, learning of the infrared repeat code is realized. The purpose of simulating the key long-press function is achieved, learning and simulation of the key long-press function of any equipment remote controller are achieved, the user experience is greatly improved, the learned infrared codes can be stored in the cloud, it is avoided that equipment needs to belearned again every time, and the installation and debugging efficiency of an Internet of Things project is greatly improved.

Description

technical field [0001] The invention relates to the technical field of infrared remote control, in particular to an infrared repetition code learning method and an infrared remote control system applied to the Internet of Things. Background technique [0002] Infrared remote control equipment is an important function in the Internet of Things system, especially for the home market. For home appliances such as TVs, set-top boxes, and air conditioners, except for a few open serial ports and IP control interfaces, the mainstream way It is still controlled by sending infrared signals. However, the infrared control codes of products from different manufacturers are incompatible with each other, and the infrared control codes of different types of products from the same manufacturer are also incompatible. In order to be compatible with different infrared devices, an infrared remote control code learning method has emerged. After the learning is completed, different infrared devic...

Problems solved by technology

[0003] However, there are traditional infrared remote control coding learning methods, which can only simulate the click function of the infrared remote control button, and cannot simulate the long press function, which is especially important for controlling TVs, players and other equipment, such as controlling TVs through the original remote control Quickly change the channel or quickly increase or decrease the volume. If the long press function cannot be learned, the user can only click the same button repeatedly, and the experience will be very bad.
