Referring to FIG. 2, FIG. 2 is a schematic diagram of a smart home system.

For smart home, it has multiple brands. For multiple brands, the control gateway cannot identify and control multiple smart homes of different brands. For example, the user only needs to send commands through a specific app to control the gateway to realize the corresponding brand. It is impossible to achieve cross-brand control, which affects the user experience.

Referring to Figure 3, Figure 3 provides a control method for a smart home, the method is implemented in the smart home system shown in Figure 2, the method is shown in Figure 3, including the following steps:

Step S301, the control gateway receives a first control command, where the first control command includes: operation signaling and a control object identifier;

The above-mentioned first control command may be a general control command, and the above-mentioned operation signaling may be control signaling such as temperature value, ON, OFF, and the like. The control object identifier may specifically be a smart home identifier, specifically, an identifier of an air conditioner or an identifier of a smart TV.

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

The above-mentioned instruction library may be a pre-configured instruction library, and the instruction library may include instruction libraries of various brands, such as Xiaomi instruction library, Gree instruction library, Samsung instruction library, and so on.

Step S303: The control gateway sends the first instruction to the control object to control the control object.

The technical solution provided by the present application controls the gateway to receive a first control command, where the first control command includes: operation signaling and a control object identifier; the control gateway parses the first control command to obtain the operation signaling and the control object identifier, and according to the control The object identifier determines the first brand of the control object, and extracts the first instruction corresponding to the operation signaling from the instruction library of the first brand; the control gateway sends the first instruction to the control object to control the control object. The technical solution provided by the present application realizes the control of control objects of different brands by pre-configuring the instruction library of each brand on the control gateway, and then extracting the first instruction corresponding to the operation signaling, thereby realizing the control across brands and improving the user experience.

Illustratively, after parsing and obtaining the operation signaling and the control object identifier, the above method may further include:

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

In this case, if the priority of the operation object corresponding to the terminal (that is, the identity corresponding to the fingerprint image) is not enough, then it cannot control the smart home, for example, to control the smart door lock, then the priority of the operation object must be very high. Ordinary personnel will not be able to control the opening or closing of smart door locks to avoid security problems.

Illustratively, the above-mentioned verification of the fingerprint picture to determine the first identity of the fingerprint picture may specifically include:

The control gateway identifies the RGB values of all pixels in the fingerprint image, determines the pixels with the same and continuous RGB values as the same texture, and extracts the same texture in the fingerprint image separately to obtain n texture images. Perform the angle recognition operation on each texture image in the image to obtain n angle values of the n texture images, and sort the n angle values according to the position of the texture (for example, according to the height value of the texture in the fingerprint image sorted from high to low) to get the first angle value sequence, compare the first angle value sequence with the template angle value sequence of the preset fingerprint template, if the alignment determines that the consecutive n values in the template angle value sequence are the same as the value of the first angle value sequence and The arrangement is also the same, it is determined that the first angle value sequence is consistent with the preset fingerprint template, and it is determined that the fingerprint image is consistent with the preset fingerprint template.

For example, if the first angle value sequence is: 6, 7, 9; the template angle value sequence is: 6, 7, 9, 2, 3. Then it is determined that the three values intercepted for the first time are the same as the sequence of the first angle value (the values are the same, and the arrangement is also the same).

The fingerprint picture is shown in Figure 4, in which the same pattern can be shown as 301 shown in Figure 4 (for the convenience of description, three identical patterns are used as an example to be marked in Figure 4), and the same pattern can be specifically: fingerprint A continuous and unbroken pattern in the picture.

Illustratively, the above angle identification operation may specifically include:

Determine the positions of the two endpoints in a texture image (point a and point b as shown in Figure 5), take point a and point b as the starting point respectively, and go to the opposite end along the texture at a set interval (point a to point b) Move, point b moves to point a) Move until the moving points a1 and b1 cross for the first time, extract the midpoint o between the moving points a1 and b1 between the lines, and connect the midpoint o to point a and point b respectively to get Line segments oa and ob, rotate the texture in the texture image so that the midpoint o is on the orthogonal line of the image (ie, the 90° angle line), move oa and ob to the outside of the texture by the first preset distance x to get o' a' and o'b', extend the line segments o'a' and o'b' by a second preset distance y to obtain the extended line segments o'a'' and o'b'', and extend the line segments o'a'' Rotate with o' as the endpoint until the line segment o'a'' is tangent to the texture and then stop rotating to obtain the line segment o'a''', and rotate the line segment o'b'' with o' as the endpoint until the line segment o'b' 'Stop rotating o'b''' when it is tangent to the texture; calculate the angle between the line segment o'a''' and the line segment o' b''', which is the angle value corresponding to the texture image.

The principle of its realization is that, for a single texture, the angle between the tangents on both sides will not change with the rotation of the fingerprint. Based on this principle, after finding the tangent of the texture, and then calculating the angle of the two tangents can be achieved. The fingerprint image is compared to realize the identity determination.

For comparison, it is determined that the consecutive n values in the template angle value sequence are all the same as the first angle value sequence and have the same arrangement. Specifically, it may include:

Intercept n values in sequence from the template angle value sequence, and compare each of the intercepted n values with the first angle value sequence. If the values are the same and have the same arrangement (that is, the same order before and after), determine the first angle value sequence and the preset fingerprint Template is the same.

For the template angle value sequence, since the fingerprint area collected by the template is large and the corresponding number of lines is also large, the number of angle values of the template angle value sequence will be greater than n, so it is necessary to intercept n values from the template angle value sequence, This comparison is performed to determine whether they are consistent. The above n is an integer of 2 or more.

Illustratively, the above method may further include:

The control gateway receives response information fed back by the control object, where the response information includes a confirmation message for executing the first instruction (if the execution is successful, a confirmation message is returned; otherwise, a failure message is returned) or a failure message. In this way, it can be realized whether the control object is successfully controlled.

Illustratively, the above method may further include:

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

Exemplarily, the above-mentioned analysis of multiple parameters to determine whether the smart home is in an abnormal situation may specifically include:

The control network extracts multiple parameter thresholds corresponding to the multiple identifiers from the smart home identifiers corresponding to the multiple parameters. If the parameter exceeds the corresponding parameter threshold, it is determined to be in an abnormal situation, otherwise, it is determined to be in a non-abnormal situation.
