[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0023] Figure 1 is a schematic flowchart of an intelligent home appliance control method provided by an embodiment of the present invention; as Figure 1 shown, the control method includes:

[0024] Step S101, establishing communication connections for multiple intelligent home appliances in the same local area network;

[0025] It should be noted that intelligent home appliances in the same space can be added to the same intelligent control system through an intelligent control terminal such as a mobile phone, and added by using the Bluetooth device or wireless wifi device of the intelligent home appliance and the intelligent control terminal to form the same local area network, and a communication connection is established between each intelligent home appliance and the intelligent control terminal.

[0026] Step S102, predicting the usage time period of each intelligent home appliance to obtain the corresponding predicted usage time period of each intelligent home appliance;

[0027] In this embodiment, as Figure 2 shown, predicting the usage time period of each intelligent home appliance to obtain the corresponding predicted usage time period of each intelligent home appliance specifically includes the following steps:

[0028] Step S201, establishing an original data sequence according to each intelligent home appliance and the usage time period;

[0029] Step S202, calculating the correlation degree between data sequences according to the original data sequence;

[0030] Step S203, establishing a differential equation according to the correlation degree between the data sequences, and obtaining a target prediction model after solving the differential equation;

[0031] Step S204: Input each smart home appliance into the target prediction model for prediction to obtain the predicted usage time period corresponding to each smart home appliance.

[0032] Optionally, the formula expression of the target prediction model is:

[0033]

[0034] where X(k) represents the usage time period, k represents the smart home appliance, α represents the development parameter, and μ represents the control parameter.

[0035] It should be noted that according to each smart home appliance and the usage time period, an original data sequence is established, the correlation degree of the original data sequence is calculated through the solution of the prior art, and a differential equation is established based on the correlation degree, where the expression of the differential equation is:

[0036]

[0037] The above differential equation is solved using the least squares method to obtain the above target prediction model, where represents the correlation degree between data sequences.

[0038] Finally, the variable of the smart home appliance is input into the target prediction model, so that the predicted usage time period corresponding to each smart home appliance can be calculated.

[0039] Step S103: According to the predicted usage time period corresponding to each smart home appliance, obtain the wake-up word response order in each time period.

[0040] In this embodiment, the wake-up word response order includes the first-rank response device, the second-rank response device, and the N-rank response device. For example, the wake-up word response order is a smart TV, a smart speaker, a smart air conditioner, and a smart refrigerator. Among them, since the usage time periods of each smart home appliance are different, the wake-up word response order corresponding to each time period is also different.

[0041] Step S104: According to the wake-up word response order in each time period, obtain the current wake-up home appliance in the current time period, and make the current wake-up home appliance respond to the wake-up word in the current time period.

[0042] In this embodiment, obtaining the current wake-up home appliance in the current time period according to the wake-up word response order in each time period includes: each smart home appliance sends a wake-up signal to the smart control terminal after obtaining the wake-up word in the current time period; the smart control terminal adjusts the wake-up word response order in the current time period according to the wake-up signal to obtain the target wake-up word response order in the current time period; and according to the target wake-up word response order in the current time period, the current wake-up home appliance in the current time period is obtained.

[0043] It should be noted that, in order to prevent smart home appliances in the wake word response order from being in the shutdown state and unable to obtain the wake word, in this embodiment, the wake word issued by the user causes all smart home appliances that are in the on state during the current time period to receive the wake word, and after obtaining the wake word, send a wake-up signal to the intelligent control terminal, so that the intelligent control terminal can understand all the currently powered-on home appliances, and then adjust the current wake word response order according to all the currently powered-on home appliances to obtain the target wake word response order; for example, in the wake word response order during the current time period, the TV is in the first position and the sound system is in the second position, but the current TV is in the shutdown state and cannot receive the wake word issued by the user, so the intelligent control terminal modifies the sound system to the first position and becomes the currently wake-up home appliance during the current time period.

[0044] Optionally, obtaining the currently wake-up home appliance during the current time period according to the target wake word response order of the current time period includes: obtaining the currently first-position response device according to the target wake word response order of the current time period; when the currently first-position response device is currently in the sleep state, using the currently first-position response device as the currently wake-up home appliance during the current time period; when the currently first-position response device is currently in the working state, detecting whether the currently second-position response device in the target wake word response order is in the sleep state; when the currently second-position response device is in the sleep state, using the second-position response device as the currently wake-up home appliance during the current time period.

[0045] It should be noted that, in order to improve the user experience and prevent the wake word from affecting the working state of the device in use, the home appliance product in the first position in this embodiment receives the user voice information to recognize the wake word, and detects whether there is a situation where the screen or audio device of this home appliance product is in use at present; if not, then the voice or screen feedback is carried out by this home appliance product; if so, then detect whether there is a situation where the screen or audio device of the home appliance product in the next feedback position in the current home appliance group control system is in use; if not, then the voice or screen feedback is carried out by this home appliance product; if so, repeat the above detection of the next position. Further, if it is detected that all home appliance products in the current home appliance group control system are in the state of using the screen or audio device, then the voice or screen feedback is carried out by the home appliance product in the first position.

[0046] In this embodiment, when the current first-rank response device is currently in a working state, it is detected whether the current second-rank response device in the wake-up word response order is in a sleep state, including: when the current first-rank response device detects that it is currently in a working state, it sends a working signal to the intelligent control terminal; the intelligent control terminal sends a working state detection signal to the second-rank response device in the current target wake-up word response order according to the working signal and the current target wake-up word response order, so that the current second-rank response device self-checks whether it is in a sleep state.

[0047] In this embodiment, when the local area network further includes an intelligent control terminal, after the current wake-up home appliance is awakened by a wake-up word, the method further includes: the current wake-up parses the voice control instruction to obtain a target control home appliance and a target operation instruction; the current wake-up home appliance sends the target operation instruction to the target control home appliance through the intelligent control terminal, so that the target control home appliance responds to the target operation instruction.

[0048] Compared with the prior art, the beneficial effects of this embodiment are:

[0049] In this embodiment, by predicting the usage time period of each intelligent home appliance, the wake-up word response order of each time period is obtained, and then the current wake-up home appliance corresponding to each time period is further obtained, so that the current wake-up home appliance responds to the wake-up words of each time period, preventing the problem of confusion caused by the same wake-up word waking up multiple products at the same time, and improving the user experience.
