For example, assuming that the preset keyword is "small letter, when the voice collecting device is in an un-awakened state, if the collected voice data triggered by the user is" small letter ", after receiving the voice data, the voice collecting device is switched to an awakened state.
When the voice acquisition equipment is in an awakening state, the voice acquisition equipment can acquire first voice data triggered by a user and send the first voice data to the central control equipment;
after receiving first voice data triggered by a user and sent by voice acquisition equipment, the central control equipment identifies the first voice data and determines a control instruction which corresponds to the first voice data and is used for controlling the running state of the controlled equipment.

in the mode 1, the central control device identifies text information corresponding to the first voice data, and performs semantic identification on the text information to determine a control instruction corresponding to the first voice data.
For example, assuming that the central control device receives first voice data triggered by a user and sent by the voice acquisition device as "turn on a water heater", the central control device recognizes text information corresponding to the voice data, performs semantic recognition on the obtained text information, and determines that a control instruction corresponding to the voice data "turn on the water heater" is "controlled device name: a water heater; the device response action: open ".

For example, if the voice data triggered by the user and sent by the voice acquisition device is "turn on the air conditioner", the central control device recognizes text information corresponding to the voice data and sends the text information to the remote server, so that the remote server performs semantic recognition, and determines that a control instruction corresponding to the voice data "turn on the air conditioner" is "the name of the controlled device: an air conditioner; the device response action: and opening', after the identification of the remote server is completed, the central control equipment receives a control instruction corresponding to the voice data returned by the remote server.
After the central control device identifies the first voice data and determines a control instruction which is corresponding to the first voice data and is used for controlling the running state of the controlled device, if the central control device determines that the first voice data comprises running parameters which are needed to be used when the controlled device runs currently, the central control device controls the running state of the controlled device according to the running parameters corresponding to the first voice data;
for example, assuming that the first voice data input by the user is "turn on the air conditioner and set the temperature to 26 ℃", the central control device determines that the control instruction for controlling the operation state of the controlled device corresponding to the first voice data is "controlled device name: an air conditioner; the device response action: and determining that the operation parameter required to be used at the current operation corresponding to the first voice data is' temperature: 26 ℃, the central control equipment is controlled according to the determined operating parameters "temperature: 26 c "controls the operating state of the air conditioning apparatus.

In some embodiments of the present application, the central control device may determine, in different manners, the target operation parameters that need to be used when the controlled device is currently operating, for a user who has been registered with a voiceprint and a user who has not been registered with a voiceprint.
The following is directed to two types of users, in conjunction with specific embodiments: respectively introducing a method for determining target operation parameters needed to be used by the controlled equipment when the controlled equipment is currently operated by the central control equipment if the first voice data does not include the operation parameters needed to be used by the controlled equipment when the controlled equipment is currently operated by users who have been registered with voiceprints and users who have not been registered with voiceprints:
type 1, user is a user who has registered for voiceprint.
In some embodiments, after determining the user identifier of the user, the central control device determines whether the stored correspondence between the user identifier corresponding to the controlled device and the operating parameter includes the user identifier of the user;
if so, the central control equipment takes the operation parameters corresponding to the user identification of the user as target operation parameters needed to be used by the controlled equipment in the current operation;
for example, assuming that the user ID is a user ID, the correspondence between the stored user ID corresponding to the air conditioning equipment and the operation parameter is shown in table 1:
table 1, user identification and operation parameter corresponding relation table.
Wherein: the operation parameter corresponding to the user with the user ID of 2000 is 20 ℃; the operation parameter corresponding to the user with the user ID of 2001 is 23 ℃; the operation parameter corresponding to the user having the user ID of "2002" is "21 ℃. Assuming that the user is identified and the user ID of the user is "2001", the target operation parameter corresponding to the user is determined to be "23 ℃.
If not, the central control device takes the operation parameter of the controlled device in the last operation as the operation parameter needed by the controlled device in the current operation, or the central control device takes the operation parameter preset by the controlled device as the operation parameter needed by the controlled device in the current operation.
For example, it is assumed that the stored correspondence relationship between the user identifier corresponding to the air conditioning equipment and the operation parameter includes: the operation parameter corresponding to the user with the user ID of 2004 is 15 ℃; the operation parameter corresponding to the user with the user ID of 2005 is 19 ℃; if it is determined that the user ID of the user is "2006", the central control device determines that the stored correspondence between the user identifier corresponding to the air conditioning device and the operating parameter does not include the target operating parameter corresponding to the user with the user identifier of "2006", and the central control device takes the latest operating parameter of the air conditioning device, which is "12 ℃, as the operating parameter that needs to be used when the current controlled device operates;
for another example, assume that the stored correspondence between the user identifier and the operating parameter for the water heater device includes: the operation parameter corresponding to the user with the user ID of 2010 is 70 ℃; the operation parameter corresponding to the user with the user ID of 2011 is 75 ℃, and the operation parameter of the preset water heater equipment is 73 ℃; and assuming that the user ID of the user is determined to be "2013", the central control device determines that the stored corresponding relationship between the user identifier corresponding to the water heater device and the operation parameter does not include the target operation parameter corresponding to the user with the user identifier of "2013", and the central control device takes the preset operation parameter "73 ℃" of the air conditioner device as the operation parameter required to be used when the current water heater device operates.
It should be noted that, in the correspondence between the user identifier and the operation parameter corresponding to the controlled device stored in the embodiment of the present application, the operation parameter corresponding to each user identifier is determined according to the operation parameter of the controlled device when the controlled device is used by the user in the history.
In some embodiments, the correspondence between the user identifier and the operating parameter may be generated according to the following manner:
in the mode 1, the operation parameter corresponding to each user identifier in the corresponding relation is the operation parameter with the largest use frequency when the user uses the controlled equipment historically.
For example, when the user with the user ID "2001" uses the controlled device air conditioner historically, the historical operating parameters of the air conditioner are "23 ℃, 24 ℃, 25 ℃ and 24 ℃, and then the central control device takes the operating parameter" 24 ℃ with the largest number of times of use by the user as the operating parameter corresponding to the user with the user ID "2001" in the corresponding relationship; when the user with the user ID of "2002" uses the controlled device air conditioning equipment historically, the historical operating parameters of the air conditioning equipment are "20 ℃, 21 ℃, 24 ℃, 20 ℃ and 23 ℃, and then the central control device takes the operating parameter" 20 ℃ with the largest user use frequency as the operating parameter corresponding to the user with the user ID of "2002" in the corresponding relationship.
And 2, the operation parameter corresponding to each user identifier in the corresponding relation is an average value of the operation parameters when the controlled equipment is used according to the user history.
For example, when the user with the user ID of "2001" uses the controlled device air conditioner historically, the historical operating parameters of the air conditioner are "15 ℃, 16 ℃, 14 ℃ and 16 ℃", and the central control device takes the average value "15" of the historical operating parameters as the operating parameters of the air conditioner corresponding to the user with the user ID of "2001" in the corresponding relationship; when the controlled device air conditioner is used by the user with the user ID of "2002" in the history, the historical operating parameters of the air conditioner are "12 ℃, 14 ℃ and 14 ℃, and then the central control device takes the average value" 14 "of the historical operating parameters as the operating parameters of the air conditioner corresponding to the user with the user ID of" 2002 "in the corresponding relationship.
Type 2, user is a user who is not voiceprint registered.
In some embodiments, the central control device takes the operation parameter used by the controlled device at the last operation time as the target operation parameter needed to be used by the current controlled device at the operation time.
For example, when the user is a user who is not registered with a voiceprint, assuming that the controlled device is an air conditioner and the last operation parameter of the air conditioner is "21 ℃", the central control device takes the last operation parameter "21 ℃" of the air conditioner as the operation parameter that needs to be used when the current air conditioner is operated.
In other embodiments, the central control device obtains an operation parameter preset by the controlled device, and the operation parameter is used as an operation parameter required by the controlled device when the controlled device is currently operated.
For example, when the user is a user who is not registered with a voiceprint, assuming that the controlled device is an air conditioning device and the preset operating parameter of the air conditioning device is "20 ℃", the central control device takes the preset operating parameter "20 ℃" of the air conditioning device as the operating parameter that needs to be used when the current air conditioning device operates.
After the central control device determines a control instruction for controlling the running state of the controlled device corresponding to the first voice data and acquires a target running parameter which needs to be used when the controlled device runs currently, the central control device generates control information for controlling the controlled device;
the central control device sends operation information containing the operation parameters and the control instructions to the controlled device, the controlled device executes the operation corresponding to the control instructions after receiving the operation information, and determines the operation state according to the operation parameters.
In implementation, the central control device sends operation information including the control instruction and the currently-used operation parameters to the controlled device according to the address information corresponding to the controlled device, and the controlled device executes the operation corresponding to the control instruction after receiving the operation information and determines the operation state according to the currently-used operation parameters.
In some embodiments, the address information corresponding to the controlled device is preset as an IP address of the controlled device.
For example, the control instruction included in the operation information is "controlled device name: an air conditioner; the equipment responds to the operation: the target operation parameter corresponding to the user with the user ID of 2001 is 26 ℃, and the central control equipment sends the operation information to the air conditioning equipment according to the IP address of the air conditioner;
the air conditioner sets the operation state to the on state after the received operation information, and sets the temperature parameter at the current operation to 26 ℃.
After the central control device sends the operation information to the controlled device, the central control device also generates corresponding voice information to be played; and the central control equipment sends the generated voice information to be played to the voice acquisition equipment for playing.
For example, the initial operating state of the controlled device is a closed state, after the central control device sends the operation information including the opening instruction to the controlled device, the corresponding to-be-played voice information is generated, that is, the device is opened and the operating state is adjusted, and the generated to-be-played voice information is sent to the voice acquisition device for playing.
For another example, after the central control device sends the operation information including the start instruction to the controlled device, the central control device generates corresponding to-be-played voice information that the current device is running and the operation state has been adjusted according to your requirements, and sends the generated to-be-played voice information to the voice acquisition device for playing.
In the embodiment of the application, after the operation information is sent to the controlled device, in the process of running the controlled device, in order to meet different requirements of the user in different time periods, the running parameters corresponding to the user identifier of the user can be updated in the stored corresponding relationship between the user identifier corresponding to the controlled device and the running parameters.
In some embodiments, if the central control device determines that the operation parameter of the controlled device changes in the process of using the controlled device by the user who has been registered with the voiceprint, the operation parameter corresponding to the user identifier of the user in the correspondence relationship between the user identifier and the operation parameter is updated according to the changed operation parameter.
In implementation, the central control device updates the operation parameters corresponding to the user identifier of the user in the corresponding relationship between the user identifier and the operation parameters according to the changed operation parameters and the operation parameters of the controlled device when the user uses the controlled device historically.
For example, assuming that the controlled device is an air conditioner, and the operating parameters of the air conditioner change from 25 ℃ to 26 ℃ in the process that the user with the user ID of "2000" uses the air conditioner, the user updates the operating parameters corresponding to the user with the user ID of "2000" in the correspondence relationship between the user identifier corresponding to the air conditioner and the operating parameters according to the changed operating parameters of 26 ℃ and the operating parameters of the controlled device "26 ℃, 24 ℃, 26 ℃, and 25 ℃" when the user uses the controlled device historically.
In the embodiment of the application, after the central control device identifies voice data triggered by a user and determines a control instruction corresponding to first voice data and used for controlling the running state of the controlled device, a target running parameter corresponding to the user is determined from a stored corresponding relationship between a user identifier corresponding to the controlled device and a running parameter according to a user identifier of a user triggering the voice data, so that the controlled device executes an operation corresponding to the control instruction and determines the running state according to the determined target running parameter, because the target running parameter is determined according to the running parameter of the controlled device when the controlled device is used by the user according to the history, and the corresponding relationship between the stored user identifier corresponding to the controlled device and the running parameter can be dynamically updated according to the requirements of the user at different moments, the running state of the controlled device can be controlled according to the running parameter preferred by the user, the probability of readjusting the operation parameters by the user is reduced, and the use experience of the user is improved.
