Optionally, the establishing an association relationship between the sensor and the home appliance device includes: sending an instruction for establishing connection with the household appliance to the sensor to enable the sensor to establish an association relationship with the household appliance; or, sending an instruction for establishing connection with the sensor to the household appliance to establish an association relationship between the household appliance and the sensor; or reading the environmental parameters detected by the sensor and sending the environmental parameters to the household appliance.
Under the condition that the control center sends a command for establishing connection with the household appliance to the sensor, the sensor actively establishes communication connection with the household appliance, namely, an association relation is established; under the condition that the control center sends a command for establishing connection with the sensor to the household appliance, the household appliance actively establishes communication connection with the sensor, namely, an association relation is established; under the condition that the control center reads the environmental parameters detected by the sensor and sends the environmental parameters to the household electrical appliance, the control center establishes a communication channel between the sensor and the environmental parameters, namely, establishes an incidence relation between the sensor and the household electrical appliance.
In some intelligent homes, a sensor for detecting environmental parameters and a household appliance for adjusting the environmental parameters are independently arranged, for example, temperature sensors are arranged in a living room, a bedroom and a corridor, air conditioners are arranged in the living room and the bedroom, and air conditioners are arranged in the corridor. At this time, when the temperature in the corridor needs to be adjusted, the ambient temperature needs to be obtained through the temperature sensor arranged in the corridor, and the air conditioner installed in the bedroom is selected to work, or the air conditioner installed in the living room is selected to work, or both the air conditioners are simultaneously selected to work, so that the adjustment of the ambient temperature in the corridor is realized. When an air conditioner installed in a bedroom is selected to work, establishing an incidence relation between a temperature sensor arranged in a corridor and the air conditioner in the bedroom; when an air conditioner installed in a living room is selected to work, the association relationship between the temperature sensor arranged in the corridor and the air conditioner in the living room is established.
And after the second keyword in the user voice is obtained, the sensor for obtaining the environmental parameter and the household appliance for adjusting the environmental parameter are convenient to determine, so that the environmental parameter is convenient to directly adjust, and the time for the household appliance to respond to the user voice is shortened.
Optionally, controlling the relevant household electrical appliance device through the control index corresponding to the second keyword to adjust the scene state includes: and sending the control index to the household appliance. When the control index comprises the set state of the household appliance, the household appliance acts according to the set state; and under the condition that the control index comprises the set parameter, the household appliance adjusts the environmental parameter according to the set parameter.
In some application scenes, under the condition that the user voice simultaneously comprises a first keyword and a second keyword, the control method of the voice recognition-based family scene linkage intelligent home system can be successfully executed, and at the moment, the user is reminded of successfully responding to the user voice. For example, the voice reminding device reminds the user that the voice of the user is successfully responded, or the light reminding device reminds the user that the voice of the user is successfully responded, or the vibration device reminds the user that the voice of the user is successfully responded in the case that the control center is a mobile terminal. By using the technical scheme, the user can definitely know whether the voice of the user is successfully responded, and the phenomenon that the user repeatedly inputs the voice is reduced.
Optionally, after the association between the sensor and the home appliance is established, recording duration of the association between the sensor and the home appliance is started, resetting the first keyword when the user finishes the voice and the second keyword is not analyzed, and keeping the association between the sensor and the home appliance when the duration is less than or equal to a set duration.
And under the condition that the duration is less than or equal to the set duration and the first keyword which is the same as the last time is analyzed again, resetting the recorded duration for establishing the association relationship between the sensor and the household appliance, namely, re-recording the duration.
And clearing the association relation between the reserved sensor and the household appliance under the condition that the duration is longer than the set duration and the first keyword different from the last time is analyzed. Acquiring a sensor corresponding to the new first keyword, establishing connection with the sensor, and reading an environmental parameter detected by the sensor; and acquiring the household appliance corresponding to the new first keyword, establishing connection with the household appliance, reading the state of the household appliance, and establishing an association relationship between the sensor and the household appliance.
And clearing the association relation between the sensor and the household appliance equipment under the condition that the duration is longer than the set duration. And in the process of clearing the association relationship between the sensor and the household appliance, clearing the environmental parameters detected by the sensor and clearing the read household appliance device.
The set duration can be used for representing the reaction rate of the control center, the longer the set duration is, the longer the user interval is (is less than or equal to the set duration), the same first keyword is input again, and the control center can still quickly react; the shorter the set time is, the shorter the user interval (less than or equal to the set time), the same first keyword is input again, and the control center can quickly respond. The set duration can be set according to a specific use scenario, and the embodiment of the disclosure does not specifically limit the set duration.
In some application scenarios, after the user inputs voice to the control center, and in the case that the control center has already parsed out the first keyword, the user stops the voice input due to some special cases. At the moment, the control center operates according to the technical scheme, when the user inputs the voice again to supplement interrupted uncompleted voice input, the control center keeps the association relationship between the last sensor and the household appliance and does not need to be reestablished, so that the voice input by the user can be responded more quickly.
