Description

A control method for home appliances

technical field

The invention relates to the field of smart home, in particular to a control method for household appliances.

Background technique

With the development of science and technology and the improvement of people's living standards, television sets and related home appliances, such as TV set-top boxes, digital versatile disc (Digital Versatile Disc, DVD) players, audio control equipment, etc., have been widely popularized.

At present, infrared remote controllers are generally used to control these home appliances, but the encoding protocols of various infrared remote controllers are different, so that most remote controllers cannot be mixed. That is, when operating different home appliances, the remote control corresponding to the home appliances must be used for control. And along with the increase of the type and quantity of home appliances, the number of remote controllers is also increasing, which brings great inconvenience to users. For this reason, someone has proposed " universal remote control ". Through the "universal remote control", the infrared code of the remote control of the home appliance can be learned. After the learning is successful, the user can control the corresponding home appliance through the "universal remote control". However, as the number of home appliances that can be controlled and managed by the "universal remote control" increases, the infrared codes of the remote controls of some home appliances may be the same or similar. In this way, the "universal remote control" may be The serial code phenomenon occurs, and the household appliances that should not be controlled are miscontrolled, resulting in misoperation of the household appliances.

Contents of the invention

Embodiments of the present invention provide a control method for household electrical appliances to at least solve the problem in the prior art that the infrared codes of multiple household appliances are the same or similar. The technical problem of miscontrol of home appliances can realize accurate control of home appliances and avoid misoperation of other home appliances.

In order to achieve the above object, embodiments of the present invention adopt the following technical solutions:

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

In order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish the same or similar items with basically the same functions and functions. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order.

Embodiment one,

An embodiment of the present invention provides a control method for a household electrical appliance, specifically as shown in FIG. 1 , including:

S101. The smart TV box acquires a first infrared code corresponding to a first home appliance in the home appliance group.

Referring to FIG. 2 , the home appliance group 20 includes a plurality of home appliances 201 to be controlled around the TV 10 (such as TV set-top boxes, DVD players, audio equipment, etc.), connected to the TV 10 through the smart TV box 30, and the TV 10 as the display screen. It should be noted that the smart TV box 30 can be provided with various I/O interfaces A, such as high-definition multimedia interface (HighDefinition Multimedia Interface, HDMI), AV composite video interface, etc., to connect the home appliance 201 and the smart TV box 30, and the smart TV box 30 and the TV set 10. This embodiment of the present invention does not specifically limit it.

Specifically, the infrared codes of all the home appliances in the home appliance group can be pre-stored in the smart TV box, and the first home appliance and the specific control instruction (such as "previous song") can be determined according to the user's input on the operation panel of the smart TV box. ", "Next Song", "Fast Forward", "Rewind", etc.) to obtain the corresponding first infrared code.

S102. The smart TV box adds a first redundant code to the first infrared code to obtain a first infrared code added with the first redundant code, where the first redundant code is used to identify the first household electrical appliance.

That is, in addition to controlling the home appliance through the operation panel of the smart TV box, the user can also control the group of home appliances through the remote control of the smart TV box, which is not specifically limited in this embodiment of the present invention.

Preferably, in the method for controlling a household electrical appliance provided in an embodiment of the present invention, the carrier frequency of the remote controller of the smart TV box is different from the carrier frequency of the remote controller of the first household appliance. In this way, mutual interference between the infrared codes sent by the remote control of the smart TV box and the infrared codes sent by the remote control of the home appliance can be avoided, thereby preventing the remote control of the home appliance from misoperating the smart TV box. It should be noted that the most typical carrier frequency is 38kHz, and the more common carrier frequencies are 36kHz, 41kHz, 56kHz, etc., and the demodulation frequency of the receiving end is 30kHz)60kHz, so 48kHz or 50kHz can be selected as the remote control of the smart TV box The carrier frequency of the device is not specifically limited in this embodiment of the present invention.
