As shown in fig. 2, a method for controlling a home appliance according to an embodiment of the present invention includes the following steps.

Step 201: and determining the current task according to the received voice instruction.

The voice command is a command including a task that can be completed by the home appliance and is input by a user in a voice manner. In an alternative embodiment, the server determining the current task based on the received voice instruction comprises: the server acquires a digital audio signal of the voice instruction, extracts voice content and voiceprint information of the user in the digital audio signal, and analyzes a current task corresponding to the voice content and the voiceprint information. The current task refers to a task which is determined by the server according to the received voice command and needs to be executed by the household appliance. In an embodiment, the server obtains a digital audio signal of a voice instruction, extracts voice content and voiceprint information of a user in the digital audio signal, and determines a current task corresponding to the voice instruction according to a corresponding relationship between the voiceprint information and a user identifier pre-stored in a database and a corresponding relationship between the voice content and the task. The corresponding relation between the voiceprint information and the user identification can be formed by acquiring voice input by a user in advance, extracting the voiceprint information by utilizing a voice recognition technology and correspondingly storing the voiceprint information and the user identification; the correspondence between the voice content and the task may be a correspondence between the voice content and the task that is preset based on matching principles such as keyword matching and semantic structure matching. Here, the server determines the user corresponding to the voice instruction through the received voice instruction, and then determines the current task corresponding to the voice content of the user. The same voice content of different user identifiers can correspond to different current tasks, for example, the user identifier A inputs a voice instruction of breakfast, the corresponding current tasks are soup making and steamed bread steaming, the user identifier B inputs the voice instruction of breakfast, and the corresponding current tasks are porridge making and bread baking.

In another embodiment, the server obtains the device identifier for sending the voice command, and determines the current task corresponding to the voice command according to the corresponding relationship between the user identifier and the household appliance pre-stored in the database and the corresponding relationship between the voice content and the task. The corresponding relationship between the user identifier and the home appliance device may be a pre-stored mapping table between the user identifier and the home appliance device. Here, the home appliance device sends the voice command input by the user to the server, and the server determines the user corresponding to the voice command through the home appliance device corresponding to the received voice command, and then determines the current task corresponding to the voice content of the user.

In another embodiment, the server obtains a digital audio signal of the voice instruction, extracts the voice content in the digital audio signal, determines a current task corresponding to the voice instruction according to a correspondence between the voice content and the task stored in advance in the database, and outputs the current task for the user to select. Here, the server determines a current task corresponding to the voice content directly according to the received voice instruction. The server can output the current task determined according to the corresponding relation between the voice content and the task to the voice hub 102, play the current task to the user in a voice mode through the voice hub 102, and receive a selection instruction of the user on the output current task; or the server can output the current task determined according to the corresponding relation between the voice content and the task to the household appliance, play the current task to the user in a voice mode through a built-in loudspeaker of the household appliance, and receive a selection instruction of the user on the output current task.

In this embodiment, the receiving of the voice command by the server refers to obtaining a digital audio signal of the voice command, and specifically includes the following two modes:

firstly, a server receives a digital audio signal of a voice instruction sent by a voice hub, the voice hub is adopted to receive the voice instruction sent by a user, the voice hub carries out preprocessing on the voice instruction, such as voice denoising and voiceprint recognition on the voice instruction, and then converts the preprocessed voice instruction into a digital audio signal to be sent to the server. The voice hub is provided with a communication module, can be connected with a routing device through a wired or wireless network, and can be in communication interaction with the server through the network connection between the routing device and the server.

Secondly, the server receives digital audio signals of voice commands sent by the household appliance, the household appliance is internally provided with a voice receiving and playing function, if the household appliance is provided with a microphone, a loudspeaker and a voice processing module, the voice commands sent by a user are received through the microphone, and are preprocessed through the voice processing module, for example, the voice commands are subjected to voice denoising and voiceprint recognition, and then the preprocessed voice commands are converted into digital audio signals to be sent to the server. Here, the household appliance is provided with a communication module, and the communication module can be connected with the server through a network, so that the household appliance can perform communication interaction with the server.

Step 202: and determining at least two household appliances completing the current task.

The server determines that at least two home appliances completing the current task can be selected in the following two optional ways: firstly, a server determines at least two household appliances corresponding to the current task according to a pre-stored corresponding relationship between the task and the household appliances. If the mapping table of the tasks and the household appliances is stored in the server in advance, the server searches the mapping table of the tasks and the household appliances according to the current task and determines at least two household appliances corresponding to the current task. Secondly, the server determines at least two household appliances corresponding to the current task according to the corresponding relationship between the pre-stored task and the household appliances and the corresponding relationship between the user identification and the household appliances. If the mapping table of the tasks and the household appliances and the mapping table of the user identifications and the household appliances are stored in the server in advance, at least two household appliances corresponding to the current tasks of the user identifications are searched and determined respectively according to the current tasks and the user identifications.

Step 203: and determining the respective required working time of the at least two household appliances for completing the current task.

Specifically, the server may determine the respective working durations required by the home appliance to complete the current task according to the content of the task and the historical data of the corresponding task completed by the home appliance. In an optional embodiment, a database of the server stores a task-to-working-time mapping table in advance, where the task-to-working-time mapping table includes a corresponding relationship between an identifier of the home appliance, a task content and a history parameter, and a required working time. For example, the home appliances are labeled "air purifier X" and "vacuum cleaner Y", the content of the task is "air purification and ground dust removal", and the historical parameters are "living room, 20 square meters"; the server determines an air purifier and a dust collector to complete the task according to the current task of air purification and ground dust removal, and then searches a task and working time mapping table to respectively obtain the respective required working time of the air purifier X and the dust collector Y for completing the air purification and the ground dust removal under the corresponding historical parameters. Optionally, the server may calculate the respective required working durations for the home appliance devices to complete the current task according to the content of the task and the historical data of the home appliance devices to complete the task. In an optional embodiment, a task and working duration mapping table is prestored in a database of the server, and the task and working duration mapping table includes calculation relationships between home appliance identifiers, task contents and required working durations under different relevant parameters. And the server calculates the required working time of the household appliance identifier for completing the task content according to different related parameters input by the user aiming at the current task. For example, the home appliance is identified as "air purifier X" or "dust collector Y", the task content is "air purification and ground dust removal", the calculation relationship of the work time required for completing the task of air purification "is" T1 ═ T1 parameter 1 ", and the calculation relationship of the work time required for completing the task of ground dust removal" is "T2 ═ T2 ═ parameter 2", the server determines "air purifier" and "dust collector" to complete the task according to the current task of "air purification and ground dust removal", and the server calculates the work time required for completing the current task of each of "air purifier" and "dust collector" according to the task-to-work time mapping table and the values of parameter 1 and parameter 2 input by the user.

And 204, controlling the starting of the at least two household appliances according to the required working time.

Here, the step of controlling, by the server, the start of the at least two home appliances according to the required working time may specifically be that, after controlling one of the at least two home appliances to start, the other home appliances in the at least two home appliances are controlled to start in a coordinated manner, and the start of the at least two home appliances is controlled in a coordinated manner, so that the working times of the at least two home appliances may overlap at least partially, and thus the total time for the at least two home appliances to complete the current task does not exceed the sum of the required working times for the at least two home appliances to complete the current task. Taking a voice command of 'cleaning and sanitation' as an example, the server determines that the current task corresponding to the voice command is 'air purification and ground dust removal' according to the voice command, determines that two household appliances completing 'air purification and ground dust removal' are respectively an 'air purifier' and a 'dust collector' according to the current task, and determines that the required working time of the 'air purifier' for completing air purification is 15 minutes and the required working time of the 'dust collector' for completing ground dust removal is 10 minutes, so that the server can start the 'dust collector' to execute the task of dust removal within the set time when the 'air purifier' is controlled to start to execute the air purification work or later. The set time length can be any time within the required working time length of the air purifier to complete the current task of air purification, namely, the air purifier can be used as long as the dust collector and the air purifier can meet the requirement of overlapping work.

In the above embodiment, the server, according to the received voice instruction, analyzes the voice instruction, determines that a plurality of household electrical appliances completing the current task and each household electrical appliance complete the required working time of the current task, and starts at least two household electrical appliances corresponding to the voice instruction according to the required working time, and starts the plurality of household electrical appliances through a voice instruction linkage, thereby facilitating the user operation, and secondly, controls the start of the at least two household electrical appliances according to the required working time, further reducing the waiting time of the user, and improving the user experience.

In another embodiment, the voice command carries an end time that requires the at least two home appliances to complete the current task at the same time, and the controlling the at least two home appliances to be started according to the required working time includes:

and respectively determining the starting time of the at least two household appliances for completing the current task according to the ending time and the required working time.

In this embodiment, the end time refers to a common end time for at least two home devices to complete respective tasks, which is determined according to the current task. The server can respectively determine respective initial time of the household appliances according to the end time carried in the user voice instruction and the required working time for the household appliances to complete respective tasks, so that the at least two household appliances can complete cooking tasks at the same time, and the intelligent experience of the user is improved. Still taking the voice command of 'clean and sanitary' as an example, the ending time carried in the voice command is 6:00 points, the server determines the corresponding current tasks as 'air purification and ground dust removal' according to the voice command of 'clean and sanitary', and respectively determining the required working time of the air purifier for completing the current task to finish the air purification to be 15 minutes, the required working time of the dust collector for completing the ground dust removal to be 10 minutes, the server controls the starting time of the air purifier to finish air purification to be 5:45(6:00-0:15), controls the starting time of the dust collector to finish dust removal to be 5:50(6:00-0:10), and controls the ending time of the air purifier and the dust collector to be 6:00, namely the air purifier and the dust collector finish respective tasks at 6:00 respectively.

In another embodiment, the server controls the at least two home devices before the starting of the starting time according to the starting time, and further includes:

Specifically, when the server detects that the current working mode of the home appliance is the non-voice working mode, if the home appliance is in the initial manual appliance working mode, the server sends the mode switching query information indicating whether to switch the at least two home appliances to the voice working mode to the voice hub, optionally, the server may also default that the current working mode of the home appliance is the non-voice working mode, and send the mode switching query information indicating whether to switch the at least two home appliances to the voice working mode to the voice hub. The server sends mode switching inquiry information, receives mode switching information which is selected by a user and used for switching the at least two household appliances into a voice working mode, and sends the mode switching information to the server, and the server controls the switching of the working modes of the at least two household appliances. For example, the server determines that the user wants to control each home appliance device through the voice operating mode according to the received mode switching information that requires the at least two home appliance devices to switch to the voice operating mode.

For another example, the server receives mode switching information that does not require the at least two home appliances to switch to the voice operating mode, and then the server sends the mode switching information that does not require the at least two home appliances to switch to the voice operating mode to the server, and the server keeps the at least two home appliances in the original manual setting operating mode.

The voice working mode refers to a process that a user carries out man-machine interaction with the server through a voice instruction to control each household appliance. The switching of the working mode comprises switching from a manual setting working mode to a voice working mode.

In this embodiment, the server achieves switching control of the operating modes of the at least two home appliances by acquiring the current operating mode of the home appliance.

and determining that the at least two household appliances are required to simultaneously complete the current task according to the received state selection information whether the at least two household appliances are required to simultaneously complete the current task.

Specifically, the server sends, to the voice hub, status query information indicating whether the at least two home appliances are required to complete a current task at the same time; the voice concentrator receives state selection information which is input by a user and requires the at least two household appliances to simultaneously complete the current task, and sends the state selection information to the server, and the server determines that the at least two household appliances are required to simultaneously complete the current task according to the state selection information. The server receives state selection information that a user does not require the at least two household appliances to complete the current task at the same time, and keeps the original working state of the starting of the household appliances in linkage control according to the required working time of each household appliance according to the state selection information which does not require the simultaneous completion.

In this embodiment, the server achieves selection control of the operating states of the at least two home appliances by sending state query information whether to request the at least two home appliances to complete a current task at the same time, and according to state selection information of a user for the state query information.

In another embodiment, the step 202 of determining at least two home devices to complete the current task includes:

Specifically, the server obtains a corresponding relationship between a task stored in a database and the home appliances, determines that each home appliance involved in completing the current task forms home appliance recommendation information, and sends the home appliance recommendation information to the voice hub.

The voice concentrator receives the household appliance recommendation information sent by the server, converts the household appliance recommendation information into corresponding voice, and informs a user in a voice broadcasting mode for the user to select. The home appliance recommendation information includes names of home appliances.

Correspondingly, the voice hub receives a voice selection instruction of the user aiming at the household appliance recommendation information, preprocesses the voice selection instruction, for example, the voice hub receives the name of at least a part of household appliances in the household appliance recommendation information input by the user voice as a voice selection instruction, performs denoising or voiceprint recognition and the like on the voice selection instruction, converts the preprocessed voice selection instruction into a digital audio signal, and sends the digital audio signal to the server.

The server receives at least two home appliances selected by a user, and specifically comprises: the server receives digital audio signals aiming at the voice selection instruction and sent by the voice concentrator, and extracts at least two household appliance names in the digital audio information; and determining the at least two household appliances completing the current task according to the at least two household appliance names.

For example, the server sends a Chinese food to the user B according to the received voice instruction, and the determined current task is 'cooking and stewing', the obtained household appliance recommendation information is 'electric cooker', 'electric casserole', 'electromagnetic oven', according to the user identifier of the user B and the current task of 'cooking and stewing', the server sends the household appliance recommendation information, and receives 'electric cooker' and 'electric pressure cooker' selected by the user, and the server determines that at least two household appliances completing the current task are 'electric cooker' and 'electric pressure cooker'.

In this embodiment, the server analyzes the voice instruction and obtains the current task, and then obtains the home appliance selection information of the user in a human-computer interaction manner, so as to control the home appliance selected by the user in time.

In another embodiment, for step 203, before determining the respective required operating durations of the at least two home devices for completing the current task, the method further includes:

receiving the selected food material type information.

Specifically, the server obtains recommendation information of each food material type related to the at least two household electrical appliances stored in the database, and sends the recommendation information of the food material type to the voice hub.

The voice concentrator receives food material type recommendation information sent by a server, converts the food material type recommendation information into corresponding voice, and informs a user of the voice in a voice broadcasting mode for the user to select; the food material type recommendation information comprises the name of each food material type.

Correspondingly, the voice hub receives a voice selection instruction of the user for the food material type recommendation information, preprocesses the voice selection instruction, for example, the voice hub receives a name of at least one food material type in the food material type recommendation information input by the user voice as the voice selection instruction, performs denoising or voiceprint recognition and the like on the voice selection instruction, converts the preprocessed voice selection instruction into a digital audio signal, and sends the digital audio signal to the server;

the server receives food material types respectively corresponding to the at least two household electrical appliances selected by a user, and specifically comprises the following steps: and the server receives a digital audio signal which is sent by a voice concentrator and corresponds to the selected voice instruction, extracts food material type information in the digital audio signal, and determines the food material type according to the food material type information.

For example, the server acquires the food material type recommendation information of "northeast rice", "thailand rice" and "glutinous rice" according to the "electric cooker", acquires the food material type recommendation information of "big bone" and "chicken" according to the "electric pressure cooker", sends the food material type recommendation information, receives the food material types of "thailand rice" and "chicken" respectively selected by the user, and determines the "electric cooker" and the "electric pressure cooker" respectively corresponding to the food material types of "thailand rice" and "chicken".

In this embodiment, after the server analyzes the voice instruction and obtains the current task and the home appliance, the server obtains the food material selection information of the user in a human-computer interaction manner, so as to timely perform corresponding control on the home appliance for selecting food materials by the user.

In another embodiment, the controlling the at least two home devices to be activated at the start time according to the start time includes:

Specifically, after determining the food material type that the user wants to select, the server further obtains the cooking power information corresponding to the food material types stored in the database, and controls the start of the at least two household appliances according to the obtained start time and the cooking power, so that the use mouthfeel of each food material after cooking is ensured.

A detailed description is given below to a specific implementation flow of the home appliance control method according to the embodiment of the present invention with reference to fig. 3.

Step 301, a voice hub receives a voice command sent by a user, converts the voice command into a digital audio signal, and sends the digital audio signal to a server.

Here, the voice hub receives a voice instruction sent by a user, preprocesses the voice instruction, converts the preprocessed voice instruction into a digital audio signal, and sends the digital audio signal to the server. The voice concentrator is also provided with a communication module which can be connected with a routing device through a wired or wireless network and is connected with a server through the routing device and the server network, so that the voice concentrator can be communicated and interacted with the server.

Step 302: and the server determines the current task according to the received voice instruction.

The server acquires a digital audio signal of a voice instruction sent by the voice hub, extracts voice content in the digital audio signal and voiceprint information of a user, and analyzes a current task corresponding to the voice content and the voiceprint information. The current task refers to a command which is required to be executed by the household appliance by the server. For example, the voice command is "breakfast", the user is user C, and correspondingly, the server recognizes the voice command and obtains the current tasks of "making soymilk, baking bread and boiling coffee" corresponding to "breakfast" of the user C pre-stored in the server.

Step 303: and the server determines at least two household appliances completing the current task.

Here, the determining, by the server, at least two home devices that complete the current task specifically includes: acquiring the household appliance recommendation information of the household appliance related to the current task, and sending the household appliance recommendation information; and receiving the information of the at least two selected home appliances completing the current task.

Specifically, the server acquires home appliance recommendation information formed by home appliances related to the current task stored in the database, and sends the home appliance recommendation information to the voice hub.

The voice concentrator converts the recommendation information of the household appliance into corresponding voice and informs a user in a voice broadcasting mode for the user to select; the voice signal includes names of the home devices.

Correspondingly, the voice concentrator receives a voice selection instruction of a user aiming at the recommended information of the household appliance, preprocesses the voice selection instruction, converts the preprocessed voice selection instruction into a digital audio signal and sends the digital audio signal to the server;

the server receives at least two home devices selected by a user. The method specifically comprises the following steps: the server receives a digital audio signal aiming at the voice selection instruction sent by the voice concentrator and extracts at least two pieces of home appliance information in the digital audio signal; and determining the at least two household appliances according to the at least two household appliance information.

For example, according to the current task of "make soybean milk, toast and cook coffee" of the user C, the server obtains the recommended information of the home appliances as "soybean milk maker", "toast maker", "pizza oven", "cake maker" and "coffee maker", and the user selects "soybean milk maker", "toast maker" and "coffee maker", so that the server determines that at least two home appliances that complete the current task are "soybean milk maker", "toast maker" and "coffee maker".

Step 304: and the server determines the food material types respectively corresponding to the at least two household appliances.

Here, the determining, by the server, the food material types respectively corresponding to the at least two home appliances includes:

the server acquires food material type recommendation information corresponding to the at least two household appliances and sends the food material type recommendation information;

receiving the selected food material type information.

The voice hub converts the food material type recommendation information into a corresponding voice signal, and informs a user of the voice signal in a voice broadcasting mode for the user to select; the speech signal comprises the name of each food material type.

Correspondingly, the voice concentrator receives a voice selection instruction of the user aiming at the food material type recommendation information, preprocesses the voice selection instruction, converts the preprocessed voice selection instruction into a digital audio signal and sends the digital audio signal to the server;

and the server receives food material types respectively corresponding to the at least two household appliances and selected by a user. The method specifically comprises the following steps: and the server receives a digital audio signal which is sent by a voice concentrator and corresponds to the selected voice instruction, extracts food material type information in the digital audio signal, and determines the food material type according to the food material type information.

For example, if the server determines that the food material types acquired by the "soymilk machine" are "soybean", "red bean" and "green bean", the food material type recommendation information acquired by the "coffee machine" is "coffee bean" and "instant coffee", and the user selects "soybean" and "coffee bean", the server determines that the food material types corresponding to the "soymilk machine" and the "coffee machine" are "soybean" and "coffee bean", respectively.

Step 305: and the server determines the respective working power of the at least two household appliances according to the selected food material type information.

Specifically, the determining, by the server, the respective operating powers of the at least two household appliances according to the selected food material type information includes:

after determining the food material types which the user wants to select, the server also acquires the cooking power information respectively corresponding to the food material types stored in the database. Here, it is assumed that after the server searches the database, the working power of the "soymilk maker" completing "making soymilk" is P1, and the working power of the "coffee maker" completing "making coffee" is P2.

Step 306: and the server determines the respective required working time of the at least two household appliances for completing the current task.

Here, the respective required working time lengths of the at least two home appliances for completing the current task are the time lengths required by the home appliances for cooking food types in different parameter ranges.

The voice instruction further comprises parameters corresponding to the food material types.

The server obtains the parameters, and the interaction process of obtaining the specific parameters is the same as the interaction process of obtaining the food material types in step 304. And a task and working duration mapping table is prestored in the server database and comprises calculation relations between household appliance identifications and task contents and required working durations under different relevant parameters. And then, the server calculates the working time required by the at least two household electrical appliances to cook the food material types under the parameter values according to the parameter values of the corresponding relevant parameters input by the user.

For example, the parameters include the weight of the type of food material, the server determines that the input parameter of the user B for "soybean" is "15 g" and the input parameter for "coffee bean" is "8 g", correspondingly, the required working hours of "15 g" and "8 g" respectively for cooking "soybean" and "coffee bean" pre-stored in the database are acquired, and if the acquired working time of "soybean milk machine" is 15 minutes and the required working time of "coffee machine" is 10 minutes, the server determines that the required working hours of the "soybean milk machine" and the "coffee machine" for completing the current task are 15 minutes and 10 minutes respectively.

Step 307, the server sends mode switching query information whether to switch the at least two home appliances to the voice working mode; if yes, the current working mode of the household appliance is switched to the voice working mode, and then step 308 is executed, and if not, step 308 is directly executed. Specifically, the server sends mode switching query information on whether to switch the at least two home appliances to the voice working mode to the voice hub, receives mode switching information on whether to switch the at least two home appliances to the voice working mode selected by the user, and controls switching of the working modes of the at least two home appliances according to the mode switching information. For example, the server determines that the user wants to control each home appliance device through the voice operating mode according to the received mode switching information that requires the at least two home appliance devices to switch to the voice operating mode. For another example, the server receives mode switching information that does not require the at least two home appliances to switch to the voice operating mode, and then the server maintains the at least two home appliances in the original operating mode according to the mode switching information that does not require the at least two home appliances to switch to the voice operating mode.

Step 308, the server sends status query information for determining whether the at least two home appliances are required to complete the current task at the same time; if yes, go to step 309; if not, go to step 310.

Step 309, the voice command further carries an end time for requiring the at least two home appliances to complete the current task at the same time, and the server respectively determines the start time for the at least two home appliances to complete the current task according to the end time and the required working time; and controlling the starting of the at least two household appliances at the starting time according to the starting time.

Specifically, the server sends, to the voice hub, status query information indicating whether the at least two home appliances are required to complete a current task at the same time; and if the server receives the state selection information that the user requires the at least two household appliances to simultaneously complete the current task, determining that the at least two household appliances are required to simultaneously complete the current task. The voice command also carries the end time of requiring the at least two household appliances to complete the current task at the same time; and the server respectively determines the starting time of the at least two household appliances for completing the current task according to the ending time and the required working time. The server controls the starting of the at least two home appliances at the starting time according to the starting time, and the starting method comprises the following steps: and the server controls the starting of the at least two household appliances at the starting time according to the starting time so as to enable the at least two household appliances to finish corresponding tasks at the ending time respectively.

Optionally, the controlling, by the server, the starting of the at least two home appliances at the starting time according to the starting time includes: the server determines the respective working power of the at least two household appliances according to the selected food material type information; and then, the server controls the starting of the at least two household appliances according to the starting time and the working power, so that the at least two household appliances finish corresponding tasks at the ending time respectively.

For example, the server determines that the corresponding home appliances are a "soybean milk maker" and a "coffee maker" for a voice instruction of "finishing breakfast at 8:00 am" input by the user C, and the acquired working time of the "soybean milk maker" for "15 g of soybeans" is 15 minutes, and the working time of the "coffee maker" for "8 g of coffee beans" is 10 minutes; and the obtained working power of the soybean milk machine for 15g of soybeans is P1, and the working power of the coffee machine for 8g of coffee beans is P2, so that the server starts the soybean milk machine at 7:45 in the morning by using the power P1; the coffee maker was started at 7:50 AM using power P2.

And step 310, the server controls the starting of the at least two household appliances according to the required working time.

Specifically, the server sends state query information whether the at least two household appliances are required to complete the current task at the same time to the voice concentrator, and if the server receives state selection information that the user does not require the at least two household appliances to complete the current task at the same time, the at least two household appliances are kept in the original working state, namely, after one of the at least two household appliances is controlled to be started, the server controls the starting of other household appliances in the at least two household appliances in a linkage manner. The starting of at least two household appliances is controlled in a linkage mode, so that the working time of the at least two household appliances can be at least partially overlapped, and the total time for the at least two household appliances to complete the current task does not exceed the sum of the required working time for the at least two household appliances to complete the current task.
