Title: Smart voice wake-up control method and control device thereof

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to the technical field of smart home control, and specifically relates to a smart voice wake-up control method and a control device thereof. 
     2. The Prior Arts 
     The Chinese Patent No. “CN206250518U” discloses a smart socket, including the socket body, which is called a socket module, and also includes a voice collection part, which includes a voice collection module and a voice recognition module. The voice collection module can collect the user&#39;s voice signal, and the voice recognition module recognizes the voice signal, and performs corresponding voice control according to the recognized sound signal. The solution for the on-off control of the smart socket by the user through voice commands is: when the user sends out a voice signal, the voice signal is collected by the voice collection module, and the voice recognition module recognizes the user&#39;s voice signal. In a specific operation, the configured sentence can be written into the single-chip microcomputer in the form of a string. If the received string is the same as the configured string, the single-chip microcomputer controls the electronic switch to perform the power-on action. When the user says “on”, the single-chip microcomputer can give a high level signal to the relay connected to it, so that the relay is closed and the electrical appliances connected to the socket are energized; on the contrary, when the user says “off”, the relay is disconnected and the appliance is powered off. In addition, other actions can be performed only after the user speaks the first-level command and matches the voice recognition module. The first-level command refers to a specific command, such as “turn on the TV”, “power on the washing machine”, and so on. 
     Although realizing the voice control, the above technique needs to pre-record and store all the first-level commands through the voice recognition module. Not only is the workload large, the cost is high, but there are many types of household products that may be called differently in various regions; thence, it is difficult to achieve a fully adapted naming system to all household products and meets the individual needs of users. In addition, when multiple identical socket modules are installed in the same space, multiple electrical products of the same type or of different types will be powered off or energized at the same time when used, which may easily cause misoperation and interference, failing to meet the convenience of the smart application and leading to poor user experience.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention. 
     Embodiment: referring to  FIGS. 1 to 3 , the present embodiment provides a smart voice wake-up control device, which includes a casing  1 , a main control board  2 , a control switch  3 , a voice pickup  4 , a relay  5 , an output terminal  6 , an input terminal  7 , and a work indicator capable of emitting a plurality of colors of light; the main control board  2  is connected to the control switch  3 , the voice pickup  4 , the relay  5 , and the work indicator  8  respectively, and the relay  5  is connected to the output terminal  6  and the input terminal  7 , respectively; the light color emitted by the working indicator light  8  corresponds to the color wake-up voice of the main control board  2 . 
     The casing  1  includes a face shell  11  and a bottom cover  12  that matches the face shell  11 . The input terminal  7  is a male terminal, and one end of the male terminal is fixed on the bottom cover  12 . The output terminal  6  is a female terminal and the female terminal is fixed on the main control board  2 . The face shell  11  is provided with a socket corresponding to the female jack terminal. 
     The control switch  3  is a touch switch and is located on a top surface of the face shell  11 . 
     The main control board  2  includes an MCU and an AC/DC conversion module, a setting module, a voice module, a light control module, a switch control module, and a reminder module respectively connected to the MCU. The preferred model of the MCU is CI1103 voice AI chip. The reminder module is connected with a buzzer. In setting or controlling operations, the reminder module controls the buzzer to make a beep for feedback. 
     The face shell  11  is provided with a light hole  111 , a sound hole  112 , and an opening. The light hole  111  is used to show the light from the work indicator  8 , and the sound hole  112  allows external sound to pass into the voice pickup  4 , the opening allows the buzzer to transmit the buzzer sound out of the casing  1 . 
     During operation, the control method of the smart voice wake-up control device is as follows: 
     (1) A user operates the control switch  3  to set a command light color. The colors can be red, green, blue, or yellow; in the present embodiment, only the foregoing four colors are used as examples; in other embodiments, other colors may also be included. 
     (2) The main control board  2  matches the corresponding color voice wake-up command according to the command light color; because there are four command light colors, there are four corresponding color voice wake-up command pre-stored in the MCU, including red voice wake-up command, green voice wake-up command, blue voice wake-up command, and yellow voice wake-up command. 
     (3) During operation, the MCU uses the light control module to control the work indicator  8  to continuously or blinkingly emit the command light color set in step (1); taking the setting of “red” as an example, the work indicator  8  emits red light, to conveniently remind the user that the wake-up command is a red voice wake-up command to avoid misoperation; when the voice pickup  4  receives the user&#39;s control voice command, the control voice command is converted into a voice signal by the voice module and fed back to the MCU for recognition. 
     (4) The MCU performs voice recognition on the voice signal. If the control voice command contains the corresponding color wake-up voice, the device will execute the output control command according to the user&#39;s control voice command; for example, when the user says “little red is on”, “red red open”, “red on” or “red color on”, which include the voices of “red” and “on” or “off”, the MCU makes the relay  5  turn on or off the loop between the output terminal  6  and the input terminal  7  through the switch control module to trigger other functional devices to respond accordingly; otherwise, the output control command is not executed. For example, when the user says “little green on”, “green green on”, “little yellow on” or “yellow on” and other voices without “red”, the output control command is not executed. 
     When a plurality of smart voice wake-up control devices are used in the same room at the same time, for example, four smart voice wake-up control devices are used to control lightings at four different positions, when it is necessary to control the lighting at the first position, the user only needs to check the light color of the of the work indicator light  8  of the smart voice wake-up control device at the position, for example red, the lighting at the first position is a red voice wake-up command; when the lighting at the second position needs to be controlled, the work indicator light  8  of the smart voice wake-up control device at this position emits, for example, a yellow light, the command for controlling the lighting at that position is a yellow voice wake-up command; and so on. The present invention indicates the color wake-up voice by displaying the light color of the work indicator  8 , so that the user can know the wake-up command intuitively, clearly and quickly to effectively solve the problem of misoperation or interference when a plurality of electrical products of the same or of different types are used simultaneously in the same space, which brings convenience to user&#39;s operation and effectively improves the user experience. 
     Although the present invention has been described with reference to the preferred embodiments thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
