Referring to fig. 2, fig. 2 is a schematic view of an intelligent home system, as shown in fig. 2, the intelligent home system includes: the intelligent household system comprises a control gateway and a plurality of terminals, wherein the terminals can be intelligent household equipment such as intelligent refrigerators, intelligent door locks, intelligent televisions and intelligent sound boxes, and the terminals are connected with the control gateway in a wireless mode.

For the smart home, the smart home has multiple brands, and for the multiple brands, the control gateway cannot identify and control the smart home of multiple different brands, for example, the control gateway can control the smart home of a corresponding brand only by using a command sent by a specific app, so that cross-brand control cannot be realized, and user experience is influenced.

Referring to fig. 3, fig. 3 provides a method for controlling smart home, where the method is implemented in the smart home system shown in fig. 2, and the method is shown in fig. 3, and includes the following steps:

step S301, the control gateway receives a first control command, wherein the first control command comprises: operation signaling and control object identification;

the first control command may be a general control command, and the operation signaling may be a temperature value, on, off, or other control signaling. The control object identifier may specifically be an intelligent home identifier, specifically, for example, an identifier of an air conditioner, and an identifier of an intelligent television.

Step S302, the control gateway analyzes the first control command to obtain an operation signaling and a control object identifier, determines a first brand of a control object according to the control object identifier, and extracts a first instruction corresponding to the operation signaling from a preset instruction library of the first brand;

the instruction library may be a pre-configured instruction library, which may include instruction libraries of various brands, such as a millet instruction library, a force instruction library, a samsung instruction library, and so on.

And step S303, the control gateway sends the first instruction to the control object to realize the control of the control object.

According to the technical scheme provided by the application, a control gateway receives a first control command, wherein the first control command comprises: operation signaling and control object identification; the control gateway analyzes the first control command to obtain an operation signaling and a control object identifier, determines a first brand of a control object according to the control object identifier, and extracts a first instruction corresponding to the operation signaling from an instruction library of the first brand; and the control gateway sends the first instruction to the control object to realize the control of the control object. According to the technical scheme, the instruction libraries of all brands are configured in advance in the control gateway, then the first instruction corresponding to the operation signaling is extracted, control over control objects of different brands is achieved, cross-brand control is achieved, and user experience is improved.

For example, after the analyzing to obtain the operation signaling and the control object identifier, the method may further include:

the control gateway receives the fingerprint picture (which can be sent by the terminal), verifies the fingerprint picture to determine a first identity of the fingerprint picture, extracts a first priority of the first identity, extracts a second priority corresponding to the control object identifier, if the first priority is greater than or equal to the second priority, the first control command is reserved, and if the first priority is less than the second priority, the first control command is discarded.

In this case, if the priority of the operation object (i.e., the identity corresponding to the fingerprint picture) corresponding to the terminal is not enough, the terminal cannot control the smart home, for example, control the smart door lock, the priority of the operation object must be high, and an ordinary person cannot control the smart door lock to be opened or closed, so as to avoid the problem of security.

For example, the verifying the fingerprint picture to determine the first identity of the fingerprint picture may specifically include:

the control gateway identifies the RGB values of all pixel points in the fingerprint picture, determines the pixel points with the same and continuous RGB values as the same grain, independently extracts the same grain in the fingerprint picture to obtain n grain pictures, executing angle identification operation on each grain picture in the n grain pictures to obtain n angle values of the n grain pictures, sequencing the n angle values according to the positions of grains (for example, sequencing the n angle values from high to low according to the height values of the grains in the fingerprint pictures) to obtain a first angle value sequence, comparing the first angle value sequence with a template angle value sequence of a preset fingerprint template, if the comparison determines that the continuous n values in the template angle value sequence are the same as the values of the first angle value sequence and are also the same in arrangement, determining that the first angle value sequence is consistent with the preset fingerprint template, and determining that the fingerprint picture is consistent with the preset fingerprint template in comparison.

For example, if the first angle value sequence is: 6, 7, 9; the sequence of template angle values is: 6,7,9,2,3. It is determined that the first truncated 3 values are identical to the first sequence of angle values (same values, same permutation).

The fingerprint picture is shown in fig. 4, where the same texture may be as 301 shown in fig. 4 (for convenience of description, 3 same textures are labeled in fig. 4 for example), and the same texture may specifically be: a continuous and uninterrupted line in the fingerprint picture.

For example, the angle identification operation may specifically include:

determining the positions of two end points (point a and point b as shown in fig. 5) in a texture picture, moving along the texture towards opposite ends (point a moves towards point b, point b moves towards point a) at set intervals by taking point a and point b as starting points respectively until moving points a1 and b1 cross for the first time, extracting the midpoint o between textures of moving points a1 and b1, connecting the midpoint o with point a and point b respectively to obtain line segments oa and ob, rotating the texture in the texture picture to make the midpoint o on the orthogonal line of the picture (i.e. 90 ° angle line), moving the line segments oa and ob outwards by a first preset distance x to obtain o ' a ' and o ' b ', extending the line segments o ' a ' and o ' b ' by a second preset distance y to obtain extended line segments o ' a ' and o ' b ', rotating the line segments o ' a ' with point o ' as an end point until the line segments o ' a ' is tangent to the line segments o ' a ', rotating the line o ' b ' with the point o ' as an end point until the line o ' b ' is tangent to the grain and then stopping rotating the line o ' b '; and calculating the angle between the line segment o 'a' '' and the line segment o 'b' '' to be the angle value corresponding to the grain picture.

The principle of its realization does, to single line, the angle between the tangent line on its both sides can not change along with the rotation of fingerprint, based on such principle, here find the tangent line of line after, then calculate the angle of two tangent lines and just can realize the comparison to the fingerprint picture, and then realize the definite of identity.

Determining that the n consecutive values in the sequence of template angle values are all the same as the values in the sequence of first angle values and are arranged in the same manner for the alignment may specifically include:

and sequentially intercepting n values from the template angle value sequence, comparing each intercepted n values with the first angle value sequence, and determining that the first angle value sequence is consistent with the preset fingerprint template if the values are the same and the arrangement (namely the front and back sequence) is the same.

For the template angle value sequence, because the fingerprint area collected by the template is larger and the number of the corresponding lines is also larger, the number of the angle values of the template angle value sequence is larger than n, so that n values are required to be intercepted from the template angle value sequence, and whether the values are consistent or not is determined by comparison. N is an integer of 2 or more.

For example, the method may further include:

and the control gateway receives response information fed back by the control object, wherein the response information comprises a confirmation message (if the execution is successful, the confirmation message is returned, otherwise, the failure message is returned) or a failure message for executing the first instruction. Thus, whether the control object is successfully controlled or not can be realized.

For example, the method may further include:

the control gateway periodically collects a plurality of parameters of the smart home, analyzes the parameters to determine whether the smart home is in an abnormal condition, and sends alarm information (the alarm information can be sent to a user of the smart home or a professional organization) if the smart home is in the abnormal condition.

For example, the analyzing the parameters to determine whether the smart home is in an abnormal condition may specifically include:

the control network extracts a plurality of parameter thresholds corresponding to the plurality of identifications from the intelligent home identifications corresponding to the plurality of parameters, determines that the intelligent home identifications are in an abnormal condition if the parameters exceed the corresponding parameter thresholds, and otherwise, determines that the intelligent home identifications are in a non-abnormal condition.
