Problems solved by technology
The preamble and end codes in the most common format bits are fixed formats (see figure 1 ), the existing universal air conditioner remote control only extracts the data code of the data bit when learning the infrared code, and only sends the data code plus the internal pre-stored preamble and end code of the fixed format when sending the infrared signal. For infrared codes without a unified format, that is, uncommon format bits (see Figure 2-4 ) air-conditioning equipment, the existing common universal air-conditioning remote control cannot send recognizable and correct infrared codes, so that the so-called universal remote air-conditioning function cannot be realized

The invention discloses a wireless infrared (IR) remote control device capable of really realizing multi-purpose remote control as well as an operating method thereof. The wireless IR remote control device comprises a wireless network control module, a microcontroller module, a FLASH memory and an IR module, wherein, a control receiving port of the wireless control module is connected with the microcontroller module; an IR port of the microcontroller module is connected with the IR module; and a memory port of the microcontroller module is connected with the FLASH memory. The operating method comprises the following steps: the wireless network control module transfers a command to the microcontroller module; the microcontroller module receives and analyzes IR codes from the IR module during the process of learning the IR codes; the microcontroller module analyzes and modulates the IR codes to be sent to the IR module so as to obtain encoding rules of various controlled IR equipment; and then the microcontroller module controls the IR module to send the corresponding IR codes. In the invention, remote control can be realized by virtue of the advantages of the zigbee control module.
Description
technical field [0001] The invention relates to an infrared remote control device, in particular to an intelligent infrared remote control device capable of remotely controlling any device with an infrared remote control function. technical background [0002] In the current situation that many household appliances do not provide remote control interfaces, if you want to realize remote control of household appliances, you can only start from the remote control of the household appliances themselves. The key is to design an infrared remote control that can control various home appliances with infrared remote control functions. Many universal remote controls on the market do not have the function of remote control of any infrared home appliances, especially air conditioners, because the codes of air conditioners The composition is the most complex and the types are the most numerous. The infrared code of the remote control air conditioner is composed of a format bit and a dat...
