The control system is used for controlling the working process of each component structure of the garbage classification throwing device, namely sending related working instructions to the formulated component structure. In this embodiment, the control system adopts the STM32 singlechip as the control core. The working principle of the intelligent garbage throwing system based on the STM32 single chip microcomputer is as follows: inside APP or little letter applet passes through the audio frequency that recording equipment collected in the cell-phone and passes through HTTP protocol transmission STM32 singlechip, development board received the audio frequency, then sends the audio frequency to Tengchong cloud speech recognition platform on, returns the characters after this platform discernment. After the characters returned by the cloud platform are matched with the database in the development board, the specified instructions are returned, the steering engine rotates according to different instructions, the corresponding garbage can is opened, and independent classification of garbage is achieved. The electric quantity required by the invention comes from a solar power supply system, and the invention is self-sufficient, has a throwing aspect, has skills to protect the environment, saves manpower and material resources, can also transmit knowledge in the aspect of garbage classification, and advocate leads people to love the environment.

The system adopts solar energy for power supply, solar energy is collected through the solar panel and is converted into electric energy, current flows through the charging voltage stabilizing module for processing, stable voltage is output to charge the battery, and the process is shown in figure 2. The solar charging control circuit uses an MPPT module, the MPPT module adopts a maximum power point tracking technology, and the photovoltaic battery can output higher power as far as possible when illumination changes so as to fully utilize solar energy. The product of the output voltage and the charging current is kept to be maximized, when the current output capability of the input power supply is reduced, the internal circuit can automatically track the maximum power point of the solar panel, and the module has the function of lithium battery overcharge protection. Because the load power is relatively low, a linear voltage stabilization power supply chip is selected to stabilize the electric energy output by the power supply, and the LM2940-5V linear voltage stabilization chip is selected in consideration of the size of the board. The design interface is simple, only a bypass capacitor needs to be added at the input pin, and a circuit diagram is shown in fig. 3.

The infrared sensing module is used for sensing people and animals nearby and controlling the starting of the voice recognition module. In this embodiment, the infrared sensing module employs an HC-SR501 sensor, which is a sensor that detects infrared rays emitted by a human body or an animal based on pyroelectric infrared effects, thereby outputting an electrical signal. In the present system, the sensor is also used to control the activation of the speech recognition module. And the signal output end of the infrared sensing module is connected with the voice recognition module. When the sensor does not sense that a person throwing garbage approaches the garbage can within the range of 2m, the sensor outputs a low-level voice recognition module in a dormant state, and the LED lamp is not on; when the sensor sensing has the rubbish throwing person to be close to, the sensor output high level, the voice recognition module starts, and the LED lamp lights. When the garbage thrower finishes garbage throwing and leaves, the sensor outputs low level again, each module is closed, and the LED lamp is turned off. The mode can effectively protect the STM32 development board and prolong the service life of the development board.

The voice recognition module is used for recognizing the speaking content of the garbage throwing person. In this embodiment, the speech recognition module uses an LD3320 speech recognition chip, and realizes recognition of the speech content of the garbage thrower by using a recognition technology of a "keyword speech list" in the recognition process. The chip can store about 50 key terms, each key term can reach 8 or 9 Chinese characters, and each Chinese character is represented by the corresponding pinyin. 40 different garbage names and 4 different garbage category names are prestored in the LD3320 voice recognition chip. Wherein, recoverable rubbish, harmful rubbish, kitchen garbage and other rubbish are respectively encoded with number 0 ~ 3. When the LD3320 voice recognition chip is awakened by the infrared sensing module, voice information of the name of the thrown garbage or the garbage category dictated by the user is collected, and then the voice information is recognized and matched with the pre-stored keywords. If the matching is successful, the number corresponding to the garbage is returned, the LD3320 voice recognition chip sends the returned number as an instruction to the STM32 single chip microcomputer, and the single chip microcomputer controls the SG90 steering engine module to open the garbage can cover with the corresponding number, so that a user is prompted to put the dictated garbage into the classification garbage can. If not match suitable categorised garbage bin, then the discernment is failed, returns figure 4, and the STM32 singlechip will trigger VS1053 voice broadcast chip, reminds the user how to use. Fig. 4 is a circuit schematic diagram of a voice module.

The voice playing module is used for playing the general knowledge of garbage classification and the propaganda information. In this embodiment, the voice broadcast module is implemented by using a SYN6288 chip, and the voice broadcast module uses a SYN6288 module, which has an intelligent text analysis processing algorithm, and can broadcast the specified content by inputting corresponding text in a program. The STM32 single chip microcomputer and SYN6288 voice synthesis chip are connected through UART interface, the controller can send control command and text to SYN6288 voice synthesis chip through communication interface, SYN6288 voice synthesis chip synthesizes the received text into voice signal and outputs, the output signal is amplified by power amplifier and then connected to loudspeaker for playing.

The steering engine is used for controlling the opening and closing of the garbage classification throwing device. The steering engine is arranged on each garbage can body, and specifically can be arranged on the side wall of the garbage can or on the garbage can cover. And meanwhile, the steering engine is electrically connected with the control system through the steering engine control system. In this embodiment, an SG90 steering engine is used. SG90 steering wheel is as mechanical control module, mainly accomplishes the automatic of rubbish bung and opens and shuts, can carry out the automatic control that the rubbish bung opened and shut. As shown in fig. 5, the control of the steering engine requires the main control system to generate a pulse signal, that is, the angle of the steering engine is controlled by the high level of 0.5ms to 2.5ms through PWM wave control, the control of the steering engine requires the MCU to generate a pulse signal of 20ms, and the high level of 0.5ms to 2.5ms controls the angle of the steering engine:

0.5ms- -0 degrees; 2.5 percent

1.0 ms-45 degrees; 5.0 percent

1.5 ms-90 degrees; 7.5 percent

2.0 ms-135 degrees; 10.0 percent

2.5ms- -180 degrees; 12.5 percent

For example, TIM 1: TIM1- > arr (preload value), the cout value is self-set, and by changing the value of cout, the cout and preload value are compared, thereby controlling the high time. The longer the high level time of 0.5ms-2.5ms, the larger the steering engine rotates by an angle, for example: the 0.5ms steering engine rotates through 0 degrees, and the 2.5ms steering engine rotates to the maximum angle of 180 degrees.
