[0055] Acquiring semantic information according to the voice information;

[0056] Acquire a semantic control database, wherein the semantic control database includes at least one preset semantic and a rotation drive motor control signal corresponding to each preset semantic;

[0059] The present application is further described in detail below by way of examples. It should be understood that the examples do not constitute any limitation to the present application.

[0060] In this embodiment, the solar power generation system includes not only the first solar photovoltaic panel assembly 3, the second solar photovoltaic panel assembly 4, the battery and the inverter, but also a controller.

[0061] In this embodiment, the solar cell assembly and the battery are the power supply system, the controller and the inverter are the control and protection system, and the load is the rotary drive motor. In this embodiment, the controller can detect the power generation voltage of the solar panel in real time and track the maximum voltage and current value (VI), so that the system can charge the battery with the maximum power output. It is applied to the solar photovoltaic system to coordinate the work of the solar panel, the battery, and the load.

[0062] In this embodiment, the present application may also include a relay, and the input voltage of the relay is usually 12V or 24V.

[0063] In this embodiment, the rotary drive motor is a DC motor or an AC motor.

[0064] In this embodiment, the sound control system includes:

[0065] Voice input device: Single microphone, which needs to be combined with noise reduction technology to achieve voice detection.

[0066] Voice processor: responsible for processing and recognizing voice signals. Commonly used voice processors include DSP, FPGA and SoC. SoC integrates processor core and digital signal processor, with high performance and low power consumption.

[0067] Voice output devices: mainly include speakers, suitable for public areas.

[0068] Control circuit: responsible for data transmission and command control of the entire system. Commonly used controllers include SoC, MCU and FPGA.

[0069] In this embodiment, an audio line is used to connect the voice button and the relay.

[0070] In this embodiment, the output voltage of a single solar panel is generally about 0.4 volts to 0.5 volts. For example, a solar cell assembly may contain 36 solar cells, so its output voltage is about 17 volts. The DC power source is converted from 17V to 24V through an inverter; then the 24V is stored in a battery to continuously supply power to the load rotation drive motor.

[0071] In this embodiment, the 24V power line output by the battery is connected to the positive and negative poles of the rotating drive motor, and the NO (normally open) interface of the relay is connected to the positive wiring of the motor, and the NC (normally closed) interface is connected to the negative wiring of the motor to control the opening and closing of the power supply.

[0072] In this embodiment, the ASRPRO voice recognition technology can be used in combination with the PWM control principle to achieve the forward and reverse rotation and speed adjustment of the TT motor (rotating drive motor). The speed and direction of the motor can be controlled by the digital output of the microprocessor through the MX1508 dual-channel motor drive module.

[0073] In this embodiment, the forward and reverse rotation technology and method of the voice-controlled stepper motor is realized by controlling the order of pulse input on the four-phase winding. Specifically, the rotation direction of the motor can be controlled by changing the input order of the pulses. The four-phase windings of the stepper motor are marked as A, B, C, and D respectively. When a phase winding is energized, an NS pole will be formed inside the motor to generate a magnetic field. When the change of the energized phase causes the magnetic field to rotate, the magnetic field acts on the rotor to cause it to rotate. If the stepper motor works in a double four-beat mode, the order of the pulse input on the winding is AB→BC→CD→DA→AB, and the motor will rotate in a clockwise direction, that is, forward rotation; and when the order is AB→DA→CD→BC→AB, the motor will rotate in a counterclockwise direction, that is, reverse rotation.

[0074] In this embodiment, the rotary drive motor transmits power to the rotary support frame through the gear rack. For example, in one embodiment, a first gear is provided on the rotary shaft of the rotary drive motor, and the first gear is engaged with the rack structure. A second gear is provided on the rotary support frame, and the second gear is also engaged with the rack structure. When the rotary drive motor is driven.

[0075] In this embodiment, the hydrogen fuel cell system is fixed to the rotating support frame with bolts, and the 360° rotation of the rotating support frame drives the rotation of the hydrogen fuel cell system, thereby achieving the purpose of displaying the product.

[0076] In this embodiment, the solar panel can be tested by a multimeter to see whether it can generate voltage and current; and corresponding voice commands such as "forward", "reverse", "stop" and the like can be issued to verify whether the forward, reverse and stop commands of the motor can be correctly controlled.

[0077] In addition, it is obvious that the word "comprising" does not exclude other units or steps. Multiple units, modules or devices stated in the device claim can also be implemented by one unit or the overall device through software or hardware.

[0078] Although the present invention has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements may be made thereto based on the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection claimed by the present invention.
