Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention sends voice instruction information to the control device by a user, the control device receives the voice information sent by the user, and utilizes the voice recognition function in the control device to recognize and screen the voice information, and extracts the information which needs to be recognized by the control device. The information to be identified by the control device may be data information preset corresponding to a designated function or having a pointing function, such as a brand name and an action command. The data information can extract the data pre-stored in the control device and control the controlled equipment.
In the existing control mode, the connected protocol needs to be disconnected, and the corresponding protocol needs to be reselected for connection control, but the invention utilizes the control protocol preset in the control device to perform data transmission and control in the modes of infrared, radio frequency and the like, can also realize automatic matching of the controlled equipment through voice control, adjusts the control sequence of the controlled equipment through voice, and sets the user reaction time, thereby reducing the delay time between the control equipment and the controlled equipment, enabling the controlled equipment to quickly respond, and executing the corresponding control action.
An embodiment of the present invention provides a voice control method, as shown in fig. 1, including:
s1, acquiring a first voice signal; the first voice signal can be the action words of turning on the air conditioner, turning on the television, turning on the lamp and the like.
S2, sending a time sequence control signal based on the first voice signal; the time sequence control signal is used for sequentially waking up at least one brand of target equipment; and enabling the target equipment of the corresponding brand to enter a state to be controlled through the first voice signal. When the control device receives the first voice signal, the control device also sequentially transmits the time sequence control signals, wherein the time sequence control signals can be infrared control codes of different brands.
S3, determining a response time interval of at least one brand of target equipment by using the time sequence control signal; and determining the response time interval of each brand of target equipment according to the time transmitted by the time sequence control signal. The control signal of each brand of target equipment is sent in a time-sharing manner according to a time sequence, namely the time sequence control signals have a sequence; some brand signal emission time sequences are in front of each other, some brand signal emission time sequences are behind each other, and the sequence and delay time of time sequence control signals influence the control of target equipment, so that the target equipment cannot respond to voice signals quickly to execute corresponding control operation.
Optionally, the number of the sent time sequence control signals is not less than 1, where each time sequence control signal corresponds to a brand of target device, and each time sequence control signal has a certain time length, which may be: the time length of the timing control signal sent by each brand signal from the voice control device from the beginning to the end of signal transmission is as follows: the time length of brand a is 600ms.
And combining the time length of each time sequence control signal, the reaction delay time of the user and the time length of the set time zone interval into a response time interval of the target equipment of each brand, so that the target equipment of the controlled brand can be quickly determined through the corresponding time interval.
In addition, different brands correspond to the response time of target equipment of respective brands, and by judging and comparing, the target equipment of the brand controlled by the voice signal can be determined in a certain brand response interval in which the time length of the voice signal is consistent within a certain response time. And through the reaction delay time of the user and the time length of the set time zone interval, the error and the interference between the response time intervals of the target devices of all brands can be reduced, and the response time intervals of the determined target devices of the brands can accurately correspond to the corresponding target devices.
For example: knowing that the time length of brand a is 600ms, the response delay time of the user is 100ms, and the time length of the set time zone interval is 300ms, the response time interval of the target device of one brand is the time length of brand a + the time length from the response delay time of the user to brand a + the response delay time of the user + the time length of the set time zone interval, that is, between 700ms and 1000ms, it is only necessary to determine whether the received voice signal falls within the response time interval of the set target device of brand a, and the target device of brand a can be quickly determined to be the controlled device.

For example: the control device acquires the second voice signal 'adjust temperature', and according to the time of the second voice signal, the time of the second voice signal may be 600ms of signal transmission time, and the response time interval of the brand a target device is 600-950ms, then the response time interval of the second voice signal and the brand a target device is compared, the time of the second voice signal may be signal transmission completion time, and the time of the second voice signal falls within the response time interval of the brand a target device, so that it can be determined that the brand a is the target device which correspondingly executes the second voice signal.
Another example is: the time of the second voice signal may be 1600ms, the response time interval of the target device of the brand a is 600-950ms, and the response time interval of the target device of the brand B is 1000-2200ms, so that the second voice signal cannot be compared in the response time interval of the target device of the brand a, it is necessary to determine that the brand B is the target device corresponding to the execution of the second voice signal by comparing the response time intervals of the target devices of the brand B, and meanwhile, the timing control signal of the brand B needs to be pre-adjusted or initially adjusted.
Optionally, the user may preset the response delay time of the user and the time length of the set time zone interval, and adjust the length of the delay time and the time length of the set time zone interval according to the user setting, so as to control the delay time of the target device corresponding to the brand, so that the target device of the controlled device/brand can respond quickly to implement the control action, thereby improving the execution efficiency of the control device, and the target device of the brand which can be automatically matched without manual matching through voice control, thereby facilitating the user operation and practicality. The second voice signal is a control command which is sent by the user and needs to be executed, for example: the user sends a voice command of turning on the air conditioner to the control device and then sends a time sequence control signal, while the user continues to send control command information of adjusting the temperature, and the temperature is adjusted at the time to be a second voice signal.
And S5, controlling the determined target equipment of the brand based on the second voice signal. Wherein the target device of the brand may be the controlled device.
And when a second voice signal exists in the response time zone of the brand target equipment, determining the brand corresponding to the second voice signal, and executing a corresponding control action. And performing awakening control according to the first voice signal, and determining a response time interval to judge whether a second voice signal exists in the response time interval of the corresponding brand, so that the controlled equipment can quickly respond to a control instruction sent by the control device and execute corresponding control action.
Alternative embodiments
Including S1-S5 above, where in performing S3, it is necessary to:
acquiring preset reaction time; the preset response time can be user response delay time, preset user setting time and the emission time, wherein the user response delay time and the preset user setting time can be set by a user, signal matching and comparison can be rapidly carried out by setting the user response delay time and the preset user setting time, the delay time of the controlled equipment is reduced, and the execution efficiency of the controlled equipment is improved. And determining a response time interval of the at least one brand of target equipment based on the preset reaction time and the awakening time interval of the at least one brand of target equipment.
In executing S4, as shown in fig. 2, it is necessary to execute:
s21, extracting the end time of the awakening time interval of the target equipment of at least one brand; for example: if the wake-up time interval of brand a is set to 0-600ms, the end time is 600ms.
S22, calculating the sum of the ending time and the preset reaction time to obtain the length of the response time interval of the target equipment of at least one brand; for example: the ending time is 600ms, the preset reaction time is 300ms, and the length of the response time interval of the target device of one brand is 600+300=900ms.
And S23, determining the response time interval of the at least one brand of target equipment by using the end time of the wake-up time interval of the at least one brand of target equipment and the length of the response time interval of the at least one brand of target equipment. For example, according to the obtained time length, the response time interval of a brand of target devices can be calculated to be between 600ms and 900ms.
Through the response time interval of the target equipment who sets up the brand to realize the response time interval contrast of follow-up second speech information and the target equipment of brand, determine controlled brand equipment, thereby guarantee that the messenger target equipment of brand can control the response fast. The embodiment of the invention can also adjust the delay time between the target equipment of each brand and the control device by adjusting the length of the response time interval of the target equipment of the brand, so that the target equipment of each controlled brand can be adjusted according to the needs of the user to ensure that the target equipment of the controlled brand can quickly respond to the control command of the user.
Optionally, the timing control signal includes a wake-up time interval of at least one brand of target device. The timing control signal may be an infrared control protocol of different brands of signals.
Optionally, when the timing control signal is updated based on the determined brand, the timing for waking up the target device of at least one brand is adjusted.
And when the timing sequence control signal is updated based on the determined brand corresponding to the second voice signal, adjusting the awakening time interval corresponding to the determined brand to be the first awakening time interval of the timing sequence control signal so as to obtain the updated timing sequence control signal.
Optionally, determining a brand corresponding to the second voice signal further includes:
when the second voice signal is obtained and the response time intervals of the at least two brands of target equipment are partially overlapped, comparing the response time intervals of the at least two brands of target equipment, and taking the response time interval of the first obtained second voice signal to determine the brand corresponding to the second voice signal. Since the time-series signal is sent in a time-sharing manner, there may be a case where the time lengths in the response time intervals of the two brands of target devices overlap, and at this time, when the time length of the second voice signal exactly corresponds to the time length of the area where the overlap occurs, it is necessary to determine the time length in the response time interval of the target device of the brand corresponding to the time length of the second voice signal, which is the earliest time length in the response time intervals of the two brands of target devices, so as to determine the target device of the corresponding brand.
Under the condition that the response time intervals are overlapped, the time length of the response time interval of the target equipment corresponding to the overlapped brands is compared, the first interval compared with the second voice signal is taken, so that the time sequence signals of all brands can be sent in order, the quick response can be guaranteed, and the corresponding control instruction is executed.
Optionally, the time-sharing sending of the timing control signal is performed based on the first voice signal. By time-sharing transmission, the effect of transmitting multi-path data through one line is ensured, so that one control device controls a plurality of brand devices, each controlled brand device can quickly respond, and corresponding operation instructions are executed.
Alternative embodiments
As shown in fig. 3, includes: a user 1, a voice control device 2 and a controlled apparatus 3.
When the user 1 can wake up the voice function of the voice control device 2 through the wake-up word, the voice control device 2 can transmit a signal to control the controlled equipment 3 through the voice command word, and the transmitted signal is an infrared control signal;
the voice control device 2 comprises a voice recognition unit, a control unit and a communication unit, wherein the voice recognition unit can recognize the awakening word and the voice command word, the control unit can select a corresponding control protocol and a corresponding communication mode according to the recognition result of the awakening word and the voice command word and code a control signal, and the communication unit is responsible for transmitting the control signal coded by the control unit; in the case where the voice control device 2 cannot know the brand of the equipment to be controlled explicitly, the transmitted signals will be transmitted together in time division according to a default timing sequence, as shown in fig. 5;
when the controlled brand device 3 receives the corresponding brand control signal and responds to the execution, specifically: and judging the matching of the transmitting signal and the equipment according to the response time interval between the command words, thereby realizing the adjustment of the transmitting time sequence of the control signal. Fig. 5 is an example of a time interval of the present invention, where TA, TB, and TC are the time duration from the start of signal transmission of the voice control device to the completion of signal transmission of each brand signal; tx is the reaction delay time of the user, specifically the time from the user hearing the response of the controlled equipment to speaking the voice command control; Δ T is the time length of the set time zone interval.
Wherein, the control of the device requires two voice commands, for example, after the device is turned on, the state of the device is adjusted accordingly.

Specifically, as shown in fig. 6:
first, a user reaction time Tx =1.2s, a time interval Δ T =0.4s, and respective brand completion times TA =300ms, tb =700ms, tb =1100ms are set by a computer or a voice function. Also according to fig. 4-6, after receiving the first voice command, the voice control device starts to emit an infrared signal according to a default timing:
(1) When the TA arrives, whether a second voice command is detected in a time interval A (namely, the TA + Tx arrives at the TA + Tx + delta T) or not is judged, namely, whether the second voice command is recognized in 1.5s to 1.9s after 300ms arrives, if so, the actual controlled equipment is judged to be A, and if not, the following judgment is continued;
(2) When the TB arrives, whether a second voice command is detected in a time interval B (namely, between the TB + Tx and the TB + Tx + delta T) or not is judged, namely, whether the second voice command is recognized in 1.9s to 2.3s after 700ms arrives, if so, the actual controlled equipment is judged to be B, and if not, the following judgment is continued;
(3) When the TC arrives, whether a second voice command is detected in a time interval C (namely from TC + Tx to TC + Tx + delta T) or not is judged, namely whether the second voice command is recognized in 2.3s to 2.7s after 1100ms arrives, if so, the actual controlled equipment is judged to be C, and if not, the judgment is given up.
If the time interval is overlapped when the time is set, and the second voice command falls in the overlapping time, the judgment is based on the time interval before. For example: if the time interval A and the time interval B are overlapped, when the voice command falls in the overlapped area, the judgment is carried out according to the time interval A, and after the actual controlled equipment brand is judged, the time sequence of the transmitting signal corresponding to the brand is arranged in the front or in the head.

s40, a user wakes up the voice control device; wherein the user's wake-up voice command is the voice message "XX hello" containing the name of the control device, or the voice message "hello" not containing the control device.
S41, when the user says 'turn on the air conditioner', transmitting control signals according to the time sequence of brands A, B and C; the user says 'turn on the air conditioner' as a first voice command, so that the control device sends each time sequence transmitting signal, and each brand of controlled equipment enters a standby state or executes the first voice command.
S42, when the control signal just transmits the brand A signal, the brand B signal is not transmitted;
s43, judging whether a voice command is received in the brand A time interval in the time interval shown in the figures 5-6, wherein the voice command at the moment is a second voice command, such as 'adjusting the temperature of an air conditioner';
and S44, if the brand A time interval receives the voice command, the brand A equipment responds to the received voice command, and the transmitting sequence of the brand A signal is kept unchanged.
And S45, if the voice command is not received in the time interval of the brand A, checking that the control signal just transmits the brand B signal and does not transmit the brand C signal.
And S46, judging whether the brand B time interval in the time interval receives the voice command or not.
And S47, if the brand B device receives the voice command in the brand B time interval, responding to the received voice command by the brand B device, and leading the transmission sequence of the brand B signal.
And S48, if the voice command is not received in the B brand time interval, checking that the control signal just transmits the brand C signal.
And S49, judging whether the brand C time interval in the time interval receives the voice command or not.
S410, if the voice command is received in the brand C time interval, the brand C device responds to the received voice command, and the transmitting sequence of the brand C signal is advanced.
And S410, if the voice command is not received in the brand C time interval, finishing the judgment and prompting no response.
The advantages of this embodiment:
