In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
In order to solve the problem of easy use, the application program should be as simple and convenient as possible, and because the emission of the infrared coding pulse series depends on the manufacturer of the infrared tube and the system environment in which the application operates, the invention opens the function of the emission coding pulse series of the hardware driving layer, and calls the hardware driving layer through the application program to realize the emission of the infrared high-low pulse series. Therefore, on the premise of not destroying the infrared integral service, the application program registers the bottom layer interface for realizing the transmission of the coded pulse series into the infrared SDK service, and then the interface of the application program is in butt joint with the interface of the hardware driving layer to realize the transmission of the infrared high-low pulse sequence.
Therefore, the infrared SDK service receives the infrared instruction of the cloud end, and the interface registered by the application program is butted with the interface of the hardware driving layer by calling the interface registered by the application program, so that the transmission of the coded pulse series is realized. Namely, the infrared service function is completed only according to a fixed flow, and the whole infrared process is streamlined.
The application layer of any equipment only needs to pay attention to the emission of the coded pulse series, does not need to pay attention to specific contents (such as infrared instructions of the equipment, code library attributes, encryption and decryption of code values and the like), and does not need to locally store a large number of various infrared code libraries, so that the universality and the usability are realized, the application in small storage equipment is supported, the hardware cost is saved, and the application can be simply and conveniently used on various embedded equipment.
Based on the foregoing, methods, systems, and apparatus for infrared control based on audio devices according to some embodiments of the present invention are described below with reference to fig. 1-5.
As shown in fig. 1, an infrared control method based on an audio device provided in an embodiment of the present invention includes the following steps:

(b) and the infrared emission interface of the application program calls an infrared emission interface of a hardware driving layer, and the infrared high-low pulse sequence is emitted by the infrared emission interface of the hardware driving layer.
Therefore, according to the infrared control method based on the audio equipment provided by the embodiment of the invention, the infrared SDK analyzes the received infrared code to obtain an infrared high-low pulse sequence; the application program assigns a pointer of an interface for realizing infrared emission to the infrared SDK, so that the infrared high-low pulse sequence triggers the infrared emission interface of the application program; and the infrared emission interface of the application program is in butt joint with the infrared emission interface of the hardware driving layer, namely the infrared emission interface of the application program calls the infrared emission interface of the hardware driving layer, and then the infrared emission interface of the hardware driving layer emits the infrared high-low pulse sequence. Namely, the embodiment of the invention realizes the emission of the infrared high-low pulse sequence by two stages of callback functions under the condition of only slightly changing the device in the prior art.
Among them, the callback function is explained as follows:

If you pass a pointer (address) to a function as a parameter to another function, we say that this is a callback function when this pointer is used to call the function that it points to. The callback function is not directly called by the implementer of the function, but is called by another party when a specific event or condition occurs, for responding to the event or condition.

Therefore, in some embodiments, the infrared SDK receives an infrared code corresponding to the voice infrared instruction from the cloud.
In some embodiments, after receiving the voice infrared instruction, the cloud obtains an infrared code corresponding to the voice infrared instruction through analysis.
In step (a), the infrared high-low pulse sequence triggers an infrared emission interface of the application program.
In the step, a callback functional relationship exists between the infrared SDK and the application program, namely, the application program assigns a pointer of an interface for realizing infrared emission to the infrared SDK, so that the obtained infrared high-low pulse sequence can trigger the infrared emission interface of the application program.
Furthermore, the infrared emission interface of the application program can call the infrared emission interface of the hardware driving layer, and then the infrared emission interface of the hardware driving layer emits the infrared high-low pulse sequence.
In some embodiments, as shown in fig. 3, the infrared high-low pulse sequence is transmitted to an infrared receiving end.
The infrared receiving end is generally a common infrared set top box, a traditional household appliance supporting an infrared function, and the like.
