Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. 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.
In a specific implementation mode, the power saving control method provided by the invention is used for the voice trash can, and can control other parts of the trash can except the control module to enter a standby dormant state when an effective operation instruction cannot be obtained for a long time, and the trash can is started after being waited for awakening, so that the trash can is not required to be started all the day long, and the power consumption is obviously reduced. As shown in fig. 1, the method includes:
s1: acquiring the interval duration between the current moment and the end moment of the last effective voice instruction; the last valid voice command is a command for obtaining garbage disposal at the last time, for example, the last command is "garbage dumping", after the last command is finished, if no voice signal related to the garbage can is received in 30 minutes, the voice command for "garbage dumping" sent before 30 minutes is the last valid voice command with the current time as a reference, and the interval duration is 30 minutes.
S2: if the interval duration exceeds a first duration threshold, sending a standby instruction so that the voice garbage can enters a standby mode according to the standby instruction; that is, if the first time threshold is 20 minutes, and the interval time is 30 minutes, the standby state is entered when the threshold is exceeded. In the actual use process, a microprocessor STM32 of the voice garbage can is always in a starting state, is connected with a pickup MIC through an I/O port to monitor whether a voice signal exists or not, waits for voice transmission of a voice control MIC, and controls a relay switch to be closed if the voice transmission exists so as to start an R328 voice processing module; if not, the mobile phone is continuously in the standby mode and waits for the incoming sound.
S3: when the voice garbage can is in a standby mode, if a voice instruction is acquired, a starting instruction is sent out so that the voice garbage can start the voice processing module according to the voice instruction;
s4: acquiring the starting duration of the voice processing module;
s5: if the duration is smaller than the second duration threshold and preset awakening information is obtained, sending an awakening instruction so that the voice garbage can enters a working mode according to the awakening instruction;
s6: and if the duration is judged to be greater than or equal to the second duration threshold, returning to the standby mode.
In the above steps S3-S6, that is, after the system starts the R328 voice processing module, the R328 voice processing module formally enters a normal working state, waits for the wake-up word "watt force", and when the wake-up word determines that the wake-up word arrives, the system enters a sensing mode of voice recognition and sends information to the STM32 through a serial port (UART); if no 'watt force or watt force' comes, the R328 sends information through a serial port (UART) to inform the STM32 that the standby mode needs to be entered, and then the STM32 controls the switch to be disconnected through the I/O port.
Specifically, the working mode includes an induction mode and a holding mode; after the voice garbage can enters the induction mode, voice action instructions are obtained and recognized through the voice processing module, the control module controls the voice garbage can to execute corresponding actions according to the voice action instructions, and after the execution of each voice action instruction is finished, the voice garbage can enters the holding mode; after the system enters the induction mode, the R328 voice processing module recognizes the voice command and informs the STM32 through a serial port (UART), then the voice garbage can starts to execute the action corresponding to the voice command, and after each action command is executed, the R328 voice processing module is informed through the serial port (UART), and the system is in a keeping mode.
After the voice garbage can enters a holding mode, acquiring the interval duration between the current moment and the ending moment of the last effective voice instruction; and if the interval duration exceeds a first duration threshold, sending a standby instruction so that the voice garbage can enters a standby mode according to the standby instruction. In the holding mode, when the voice command recognized by the R328 in a period of time has no correlation with the command of the voice garbage can, the voice garbage can is judged to be in an unnecessary working state, at the moment, a message is sent to the STM32 through a serial port (UART) to request to enter a power-saving long-term standby mode, then the STM32 microcontroller controls a switch to disconnect the power supply of the R328 voice processing module, and the system automatically enters the long-term standby mode.
Further, in order to improve the service performance of the device, the method further includes a control strategy capable of implementing power-on self-test, specifically including:
acquiring a starting-up instruction;
sending a self-checking instruction according to the starting instruction so that the voice garbage can enters a self-checking mode according to the self-checking instruction;
if the equipment is judged to be normal after self-checking, playing normal working information through a power amplifier module, and entering a standby mode;
and if the equipment is abnormal after the self-inspection is judged, outputting alarm information through an alarm module.
After the system opened, the whole power supplies of each hardware functional unit begin the self-checking, the self-checking is accomplished that each functional module is normal then STM32 microcontroller unit sends the instruction through the serial ports and gives R328 reminder system normal, later R328 voice processing module output sound signal, it is normal to report the system through power amplifier system, later STM32 microcontroller send instruction control power supply system cut off the power entering long term standby mode of R328, if there is the red light of problem reddish yellow blue pilot lamp lighting, loudspeaker report problem out of office and warning.
Specifically, the system can be implemented by acquiring the preset wake-up word or acquiring the infrared finger scanning command by acquiring the preset wake-up information.
For example, when sound of pickup MIC is transmitted, the STM32 microcontroller controls the relay switch in the control diagram to be closed to start the R328 voice processing module, and waits for a user to voice out a wake-up word; after the system starts the R328 voice processing module, the R328 voice processing module formally enters a normal working state to wait for the arrival of the awakening word 'Wai power', and the R328 voice processing module sends out a question through a power amplifier loudspeaker: "what need to help the host do? After 2 microphones start to pick up sound, the sound pickup is completed and translated into an instruction, and the information is sent to an STM32 microcontroller through a serial port (UART), meanwhile, a power amplification system starts to talk with a user normally, and the STM32 microcontroller controls to start controlling a flip motor to drive to open or close a cover and the like; if no 'watt force and watt force' comes, the R328 sends information through a serial port (UART) to inform an STM32 microcontroller that the long-term standby mode needs to be entered, then the STM32 is disconnected through an I/O port control switch, and a voice instruction has simple functions of opening and closing a cover and other voice dialogues.
For another example, when a command is input by the touch key, the STM32 microcontroller of the STM32 microcontroller receives system setting which mainly comprises action setting, sound setting, time setting, mode setting and the like, at the moment, the R328 voice processing module is started, the red, yellow and blue indicator lamps flicker corresponding to the action rule of the voice garbage can, and different breathing frequencies display different working states; when the instruction comes is swept to the infrared hand, the action that the STM32 microcontroller control flip motor drive of pronunciation garbage bin corresponds is executed, does not open R328 voice processing module, and yellow light is lighted to red yellow blue pilot lamp, and the closing lid is swept to the hand, and the lid is opened to the hand of once more sweeping.
It should be noted that the system can selectively enter into the standby mode, the sensing mode and the holding mode by the above method, and the operation of the device in each mode is briefly described as follows:
standby mode: under the condition of no sound for a long time after electrification and when the sound pickup MIC cannot detect the sound, the microprocessor STM32 controls the system to start a long standby mode, the R328 voice processing module is powered off, only the microprocessor of the whole system is in a working state and waits to be triggered, and the power off controls the relay to cut off the power supply through the I/O interface of the microprocessor;
induction mode: when sound enters a sensing area, the pickup MIC receives the sound and transmits the sound to the microprocessor STM32 for control, the R328 voice processing module is started, after a wake-up word is received, the garbage can starts a sensing mode and enters a voice recognition waiting state, otherwise, the garbage can enters a long-term standby mode and informs the STM32 of entering the sensing mode through a serial port;
a holding mode: when the system receives the awakening words through the R328 voice processing module and enters the induction mode, the voice garbage can starts to execute voice instructions, the system enters the holding mode, voice semantics are prepared to be analyzed at all times, and the STM32 is informed to enter the holding mode through the serial port; judging that no instruction needs to be executed during the speech dialogue and the garbage bin work in a period of time, the R328 speech processing module sends an instruction to the STM32 microcontroller through the serial port, and the request enters the long standby mode and saves power, and then the STM32 microcontroller controls the switch to disconnect the power supply of the R328 speech processing module, and the system automatically enters the long standby mode.
In the foregoing specific embodiment, according to the power saving control method for a voice trash can provided by the present invention, by obtaining an interval duration between a current time and an end time of a last valid voice instruction, and determining that the interval duration exceeds a first duration threshold, a standby instruction is issued, so that the voice trash can enters a standby mode according to the standby instruction; when the voice garbage can is in a standby mode, if a voice instruction is acquired, a starting instruction is sent out so that the voice garbage can start the voice processing module according to the voice instruction; and acquiring the duration of the start of the voice processing module, judging that the duration is less than the second duration threshold and acquiring preset awakening information, sending an awakening instruction so that the voice garbage can enters a working mode according to the awakening instruction, judging that the duration is greater than or equal to the second duration threshold, and returning to the standby mode. Therefore, the power-saving control method of the voice garbage can solves the energy consumption problem of the voice recognition module in the hardware circuit of the voice garbage can by controlling the starting and closing states of the voice recognition part, and achieves the effects of saving energy and power at any time without closing; thereby solved among the prior art voice garbage bin and continued the operation and lead to the technical problem that power consumption is big.
