Problems solved by technology

The infrared remote control systems of various home appliances on the market are mature in technology and low in cost, but the infrared remote controls used by various home appliances are not compatible, which brings inconvenience to users
At the same time, infrared transmission has its limitations. Infrared transmission cannot bypass obstacles or pass through walls. When using it, the remote control needs to be aimed at the receiving end, and the transmission distance is generally only 10 meters.
[0003] There are many types of remote controllers with learning functions on the market, but there are very few wireless remote controller manufacturers that claim to be able to learn the codes of all remote controllers and support online updates, especially for air conditioners.

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0030] Example. A universal remote control method, characterized in that: by identifying the infrared remote control signals of each device, the original data is obtained, and the infrared code in the original data is compressed by a compression method and stored as an original data table, and then decoded when used Compress and restore, to control the work of the designated infrared remote control device.

[0031] The compression methods include:

[0032] By comparing the pulse width of the original data, all pulse widths are divided into several pulse widths, which are used as compression code reference values, and the storage length is selected according to the number of pulse width types obtained, and stored in the pulse width type table;

[0033] Replace the pulse width data in the original d...

Abstract

The invention discloses a universal remote control method, which is characterized by comprising the following steps of: identifying infrared remote control signals of each piece of equipment to acquire primary data, compressing infrared codes in the primary data by using a compression method, storing the compressed infrared codes in a primary data sheet, and when the infrared codes are used, performing decompression reduction to control given infrared remote control equipment to work. By the compression method used by the universal remote control method, a data volume can be reduced to be within 1K by compression, and the highest compression ratio of 16:1 can be realized, thereby reducing a storage space required by the learning of a remote controller code to further make possible all remote controller code learning of a remote controller.

Description

technical field [0001] The invention relates to a universal remote control method, in particular to a learning type universal remote control method. Background technique [0002] With the development of society and the advancement of science, and the improvement of people's living standards, more and more multimedia devices have entered people's lives and studies. In multimedia classrooms, we often use digital equipment such as digital projectors, DVDs, VCDs, and video recorders; in modern homes, stereos, CDs, VCDs, DVDs, TVs, air conditioners, water heaters and even electric fans are common An infrared remote control device is used. The infrared remote control systems of various home appliances on the market are mature in technology and low in cost, but the infrared remote controls used by various home appliances are not compatible, which brings inconvenience to users. At the same time, infrared transmission has its limitations. Infrared transmission cannot bypass obstacl...
