BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is the structure diagram of the smart home voice control switch system. DETAILED DESCRIPTION

[0012] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] The structure diagram of the smart home voice control switch system provided by the present invention is as follows Figure 1 As shown, it includes a control processing module, a voice collection and recognition module, a peripheral auxiliary circuit module, a peripheral control module and an indication display module, wherein the voice collection and recognition module, the peripheral auxiliary circuit module, the peripheral control module, the indication display module and the control processing module are directly connected in a star shape.

[0014] The control processing module uses an S3C2440 ARM microprocessor to process voice signals and control other modules.

[0015] The voice collection and recognition module includes a microphone and a voice chip. The microphone is connected to the voice chip, and the voice chip is connected to the control processing module. The microphone is used to collect sound signals and convert them into electrical signals. The voice chip adopts LD3320, which has a built-in A / D converter and a dynamic recognition element. The A / D converter is used to realize the conversion of analog signals to digital signals, and the dynamic recognition element is used to recognize the converted digital signals and transmit the recognition results to the control processing module.

[0016] The peripheral auxiliary circuit module includes a conventional power supply circuit, a clock circuit, a reset circuit, and a debugging circuit for assisting the normal operation of the control processing module.

[0017] The peripheral control module includes a drive circuit and a switch relay. The drive circuit is connected to the control processing module to receive instructions from the control processing module and drive the operation of the switch relay; the switch relay is used to control the opening and closing of the switch of the household appliance.

[0018] The indication display module includes an LCD display device for displaying the working status of the control processing module.

[0019] The working process of the smart home voice control switch provided by the present invention is as follows:

[0020] First, the ARM microprocessor in the control processing module sets the voice template of the switch control command and transmits the corresponding digital signal to the voice acquisition and recognition module. The user issues a switch control command, and the microphone in the voice acquisition and recognition module receives the sound signal issued by the user, converts it into an analog electrical signal and transmits it to the voice chip. The A / D converter built into the voice chip converts the analog signal into a digital signal, and then the dynamic recognition element built into the voice chip recognizes the converted digital signal. If a digital signal identical to the template digital signal is recognized, the recognition result is transmitted to the control processing module. The ARM microprocessor in the control processing module analyzes and processes the recognition result with the assistance of the peripheral auxiliary circuit module. After obtaining the processing result, the control processing module issues an instruction to the peripheral control module, and at the same time displays the recognition and processing result of the digital signal on the LCD display device of the indication display module. After receiving the instruction from the control processing module, the driving circuit in the peripheral control module drives the switch relay to operate, and the switch relay controls the opening and closing of the switch of the household appliance, thereby realizing the voice control of the switch.
