The infrared coding information refers to infrared coding information corresponding to keys of a remote controller, each key corresponds to an infrared code, and each infrared code generally comprises three parts, namely a guide code, data bits and an end code. The data bits include address code, instruction code and instruction code.
The infrared code information of the remote controller is usually stored in a memory of an electrical device such as a television or a dedicated remote control chip, and the infrared code information of the remote controller can be obtained by reading the information from the memory or the remote control chip.
S20: encoding the infrared encoding information to obtain a first character string with a preset format;
it should be understood that the preset format refers to a preset data exchange format, and may be JSON (JavaScript Object Notation) format, XML (eXtensible Markup Language ) format, or other data exchange format. The JSON is a lightweight data exchange format, and is an ideal data exchange format due to the adoption of a text format completely independent of language, so that the JSON is easy to read and write by people and easy to analyze and generate by machines.
It should be noted that, after the electrical device obtains the infrared coding information, the infrared coding information may be coded into the first character string with the preset format and stored in the device configuration item.
S30: encoding the first character string to obtain identification information for reading by application software; wherein the identification information corresponds to the infrared coding information one by one.
It should be understood that the application software refers to a collection of application programs that can implement infrared intelligent control of the electrical device. The identification information corresponds to the infrared coding information one by one, after the identification information is obtained by coding the first character string, the application software can obtain the first character string by reading the identification information, and the corresponding infrared coding information is obtained by decoding.
As an embodiment, the first character string and the two-dimensional code encoding rule may be encoded, so as to obtain a two-dimensional code for reading by application software.
Taking the electrical equipment as a television, when the television stores the first character string into the equipment configuration item, the television sets the option of the application related to the equipment information, and can increase the equipment infrared remote control two-dimensional code display interface, and the interface reads the first character string stored in the equipment configuration item and codes the first character string into a two-dimensional code for display. Of course, after the two-dimensional code is formed, the two-dimensional code can be stored in a specification of the television, so that a user can conveniently scan and read the two-dimensional code through application software.
In addition, after the application software obtains the first character string by reading the identification information, the application software can decode the first character string to obtain the infrared coding information and the key name information, and correspondingly store the infrared coding information and the key name information. The application software can also generate a virtual remote control interface corresponding to the remote controller according to the key name information, and when the keys of the virtual remote control interface are triggered externally, the infrared coding information corresponding to the keys is output, so that the television can realize the functions corresponding to the keys according to the infrared coding information.
