Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer reuse technology, and in particular to a renewable resource control system. Background Technology

[0002] Currently, the main renewable resource systems on the market use heated placement methods. Existing technology involves concentrating organic fertilizer in a chamber for constant-temperature fermentation, with manual stirring after a certain period. The resulting organic fertilizer is then given to farmers for secondary use. However, due to the varying types and quantities of organic waste, the fermentation time and required temperature need constant adjustment. Manual stirring is labor-intensive and poses operational risks. Harmful gases produced during fermentation tend to accumulate and cannot be promptly released, causing significant gaseous environmental pollution in a short period when the organic fertilizer is removed. Furthermore, the level of automation is low. Therefore, a renewable resource control system is needed. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a renewable resource control system to solve the problem of low automation and manual operation required when reusing renewable resources in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A renewable resource control system, comprising:

[0006] The system includes a common-mode filter circuit, a step-down circuit, a main control circuit, and a drive circuit. The step-down circuit provides power to the main control circuit, and the main control circuit controls the operation of the drive circuit.

[0007] It also includes a hopper, on which a fan, a heater and a stirring motor are installed. The drive circuit is electrically connected to the fan, the heater and the stirring motor to control the operating status of the fan, the heater and the stirring motor.

[0008] To achieve the above technical solution, the current is filtered by a common-mode filter circuit, and then stepped down by a step-down circuit before being supplied to the main control circuit to ensure the stability of the main control circuit. The main control circuit processes the information through a microcontroller and then sends the signal to the fan, heater, and stirring motor to control the operating status of the fan, heater, and stirring motor.

[0009] In one embodiment of the present invention, the common-mode filter circuit includes a power-on connector, a common-mode inductor and an electrolytic capacitor for current filtering, and the step-down circuit includes two sets of Zener diodes that divide the circuit into two paths. A capacitor filter is also provided between the common-mode inductor and the electrolytic capacitor and the two sets of Zener diodes.

[0010] To achieve the above technical solution, the common-mode filter circuit includes a power interface DC1, a resistor R69, a surface-mount LED bead D22, a fuse F1, a common-mode inductor L2, a bidirectional TVS-D21, an electrolytic capacitor C45, a power connector P100, an L3 capacitor filter, an inductor L4, an electrolytic capacitor C46, ​​and a surface-mount capacitor C47. The step-down circuit includes: Zener diodes VR1 and VR2, surface-mount capacitors C43 and C200, and electrolytic capacitors C44 and C201.

[0011] First, power connector DC1 is applied at 12V. D22 lighting up indicates that it is powered on. The current passes through fuse F1, reverse polarity protection diode D20, and bidirectional TVS-D21, then is filtered by common-mode inductor L2 and electrolytic capacitor C45, and then passes through capacitor filter L3.

Its feedback voltage signal is amplified by the power amplifier U4A through connectors P4 and P9 and then sent to the microcontroller to detect the current temperature inside the machine. The temperature is then displayed on the three-digit LED display by the 1628 chip.

[0021] In one embodiment of this utility model, a tactile switch is provided on the hopper, and the button sampling and surface-mount LED driving circuit detects whether the tactile switch is pressed in order to control the automatic / manual mode switching of the fan, heater, and stirring motor, as well as the temperature setting switch.

[0022] To achieve the above technical solution, the 1628 chip detects whether the tactile switches KEY1-KEY5 are pressed, thereby controlling the fan, heater, stirring motor, automatic / manual mode switching, and temperature setting switch. In automatic mode, the stirring motor runs in forward and reverse directions according to the time set by the host computer, and the heater stops heating when the specified temperature is reached.

[0023] In one embodiment of this utility model, the hopper is connected to an external emergency stop switch, which transmits a signal to the microcontroller through a connector to forcibly stop the operation of the motor, fan and heater.

[0024] To achieve the above technical solution, the machine is connected to an external emergency stop switch.

[0040] Please see Figures 1 to 13 This utility model provides a renewable resource control system, including a common-mode filter circuit, a step-down circuit, a main control circuit, and a drive circuit. The step-down circuit provides power to the main control circuit, and the main control circuit controls the operation of the drive circuit. A fan, a heater, and a stirring motor are installed on the hopper. The drive circuit is electrically connected to the fan, the heater, and the stirring motor to control the operating status of the fan, the heater, and the stirring motor.

[0041] The storage circuit includes: AT24 storage chip, pull-up resistor, and filter capacitor.

[0042] After the current is filtered by a common-mode filter circuit, it is then stepped down by a step-down circuit before being supplied to the main control circuit to ensure the stability of the main control circuit. The main control circuit processes the information through a microcontroller and then sends the signal to the fan, heater, and stirring motor to control their operating status.

[0043] The common-mode filter circuit includes a power-on connector, a common-mode inductor and an electrolytic capacitor for current filtering, and a step-down circuit including two sets of Zener diodes that divide the circuit into two paths.

[0045] First, power connector DC1 is applied at 12V. D22 lighting up indicates that it is powered on. The current passes through fuse F1, reverse polarity protection diode D20, and bidirectional TVS-D21, then is filtered by common-mode inductor L2 and electrolytic capacitor C45, and then passes through capacitor filter L3. The voltage is then reduced to two 3.3V paths by Zener diodes VR1 and VR2 to power subsequent circuits, ensuring the stability of the power supply to subsequent circuits.

[0047] The main control circuit includes: U3A-STM32F103VCT6 main control chip, crystal oscillator Y1, surface mount capacitors, current limiting resistors, surface mount LED-D17, and programming port connector P15. The main control MCU single-chip microcontroller STM32F103VCT6 performs programming through programming port P15.

The data is stored under power failure through the storage chip AT24.

[0050] The mixing motor can only work after the top cover of the silo is closed. This is achieved by a sensor sending a signal to the microcontroller via P2. If a fault occurs, the fault sensor sends a signal to the microcontroller via P12, causing the microcontroller to forcibly stop the motor.

[0055] The machine has a built-in temperature sensor PT100. Its feedback voltage signal is amplified by the power amplifier U4A through connectors P4 and P9 and then sent to the microcontroller to detect the current temperature inside the machine. The temperature is then displayed on the three-digit LED display by the 1628 chip.

[0056] A tactile switch is installed on the hopper. The button sampling and surface-mount LED driver circuit detects whether the tactile switch is pressed, so as to control the automatic mode switching and manual mode switching of the fan, heater, and stirring motor, as well as the temperature setting switch.

[0057] The 1628 chip detects whether the tactile switches KEY1-KEY5 are pressed, thereby controlling the fan, heater, stirring motor, automatic / manual mode switching, and temperature setting switch. In automatic mode, the stirring motor runs in forward and reverse directions according to the time set by the host computer, and the heater stops heating when the specified temperature is reached. The temperature setting switch logic is that after pressing and holding for three seconds, the digital display enters the temperature setting interface. An external encoder is connected via connector J1 to set the start and end temperatures. After successful setting, the digital display stays lit for two seconds after the end temperature is set, and then returns to the current temperature display interface.

[0059] The machine is equipped with an external emergency stop switch.

[0061] The optocoupler sensor sampling circuit includes: optocouplers U2-U8, filter capacitors, current-limiting resistors, and surface-mount LEDs.

[0062] This invention filters the current using a common-mode filter circuit, then steps down the voltage using a step-down circuit before supplying power to the main control circuit. This ensures the stability of the main control circuit. The main control circuit processes the information using a microcontroller and then sends the signals to the fan, heater, and stirring motor to control their operating status. This reduces manual intervention and improves the automation level of the system.
