Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

After the power supply is started, the valve controller can be operated in a traditional induction control mode, an instruction can be sent out to the valve controller in a voice control mode, and after the main control chip detects a preset control instruction, the main control chip sends the instruction to an AD (analog-to-digital) converter circuit of the main control chip through the microphone circuit to sample and convert the instruction into a digital signal. The digital signal is transmitted to the voice recognition chip through the interface circuit for algorithm recognition, and after a corresponding instruction is recognized, the voice recognition chip sends a control instruction code to the valve controller to operate the electromagnetic valve for controlling the faucet. The voice recognition chip simultaneously decodes the voice broadcast segment in the current state through the audio decoding chip and outputs the decoded voice broadcast segment to the power amplifier for broadcast.

Fig. 1 shows a specific embodiment of the control system, wherein the main control chip of the speech control circuit board can select CI1006, CI1006 is a local speech recognition chip for volume production of the british taylon company, and can perform local recognition, without transmitting the audio signal to other servers or cloud terminals, so that local speech recognition can be implemented in a bad network environment, CI1006 further has data processing capability, and can output a plurality of analog or digital signals with driving capability to control other speech control devices or devices, such as a speaker, a switch tube, and other devices.

The specific audio recognition process is as follows: under the mode of voice control, a user sends a voice command, after the user sends a voice command, the voice command is collected by a microphone to be input into an audio decoding chip ES8388, the audio decoding chip ES8388 carries out digital quantization on the analog signal and then sends the analog signal to a voice local recognition chip for recognition and comparison, the voice local recognition chip CI1006 carries out local recognition and then judges an execution command needing to be output through artificial intelligence local calculation, the command is synchronously output to the audio decoding chip ES8388, the audio decoding chip ES8388 outputs the command to a power amplification chip SGM4890, the power amplification chip SGM4890 controls a loudspeaker to play the audio signal, the user is reminded and fed back, and different working states can be displayed through a display device such as an LED lamp.

ES8388 is a low-power consumption high-quality stereo audio decoding chip designed for portable audio players, which integrates a complete interface, provides two stereo headphone line output ports, and is built-in with a digital amplifier, directly supports EQ equalizer adjustment and 3D sound effect enhancement, and microphone/line output automatic level control.

The CI1006 external Flash memory stores software program, the crystal oscillator provides clock source for the voice local identification chip CI1006, the power amplifier can adopt various chips, as long as the output level signal of the decoding chip ES8388 can be identified, for example, common LM1875, the crystal oscillator can select PCF 2129.

The CI1006 may directly perform signal conversion, interaction, and control on conventional circuit elements such as keys, motors, driving chips, LED display lamps, nixie tubes, key sensing chips, etc. using its own integrated processor, I/O interface, and multiple ADC channels.

When adopting the alternating current commercial power supply mode, it is concrete, still include power management circuit, power management circuit includes AC/DC chip and the DC/DC chip of being connected with it, the DC/DC chip does the local discernment chip power supply of pronunciation, the AC/DC chip is SM7033P the DC/DC chip is SY 8088.

After the voice control system is adopted, the functions of the hand washing sink can be expanded, for example, the traditional induction type mode can only realize the opening and closing of a water tap due to the single control mode, in the specific embodiment shown in the figure 1, a heater controlled by a main control chip can be added, for example, after a voice signal of 'hot water' is recognized, the heater is turned on to heat the water and then the water is discharged, at the moment, a water pipe in the hand washing sink can be designed into a coil pipe type to be convenient for heating of the heater, and the main control chip can also be used for connecting other equipment such as a hand dryer, a tissue machine and the like.

As shown in figure 2, a circuit board for installing a voice control system can be arranged at the edge of the mirror face 1 of the hand washing basin, mainly to avoid the reduction of the service life of the circuit board and devices due to a humid environment, and in figure 2, a microphone 2 and a loudspeaker 3 are arranged on the outer vertical face of the voice area at the edge of the mirror face.

Fig. 3 shows a specific installation manner of throwing water into a microphone or a loudspeaker for a habitual hand-throwing action after washing hands of a waterproof user, and implementing the water-throwing action on a voice device such as the microphone or the loudspeaker. Outer facade is provided with sound-permeable window 4 and is located the recess 6 at sound-permeable window rear, the recess includes inclined plane and lower inclined plane, go up pronunciation devices 5 such as installation microphone or loudspeaker on the inclined plane, lower inclined plane bottom with sound-permeable window connects, and sound-permeable window generally is provided with the not syllable-dividing protector such as silk screen, even in water passes through the silk screen and gets into sound-permeable window, also is difficult to the adhesion on pronunciation device surface and further oozes inside the circuit, but drops down and flows from sound-permeable window through lower inclined plane under the action of gravity, avoids water to be detained for a long time and causes the device to wet in sound-permeable window, and is also very simple on the recess construction that two inclined planes and a pair of side are constituteed.

In the foregoing, the preferred embodiments of the present invention, if not obviously contradictory or based on a certain preferred embodiment, can be combined and used by any superposition, the specific parameters in the embodiments and examples are only for clearly expressing the utility model verification process of the utility model, and are not used for limiting the patent protection scope of the present invention, the patent protection scope of the present invention is still based on the claims, and all the equivalent structural changes made by the contents of the specification and the drawings of the present invention should be included in the protection scope of the present invention.
