[0033] The serial communication module 5 is connected to the first serial communication interface 3 and the second serial communication interface 6 .

[0034] The temperature detection module 4 (for example, SBWZ series integrated temperature transmitter) is used to collect the temperature in the organic fermentation device in real time. The temperature detection module 4 is connected to the first serial communication interface 3 through a serial line, the first serial communication interface 3 is connected to the serial communication module 5, and the serial communication module 5 is connected to the main controller 1, so that the real-time temperature collected by the temperature detection module 4 is sent to the main controller 1 through the first serial communication interface 3 and the serial communication module 5. The main controller can be a RAM microcontroller.

[0035] The human-machine interaction module 9 uses a Weiluntong MT6000 / 8000TSeries touch screen, which is used to set the temperature range in the organic fermentation device. The main controller 1 is connected to the human-machine interaction module 9 to obtain the temperature range in the organic fermentation device set by the human-machine interaction module 9.

[0036] The main controller 1 is connected to the PID control module 7 to send the acquired real-time temperature and the set temperature range to the PID control module 7. The PID control module 7 performs difference calculation based on the received real-time temperature and the set temperature range, and generates an accurate adjustment signal according to the calculation result.

[0037] The PID control module 7 is connected to the serial communication module 5, and the serial communication module 5 is also connected to the second serial communication interface 6. The second serial communication interface 6 is connected to the temperature adjustment module 8 through a serial line, so that the adjustment signal generated by the PID control module 7 is used to cool or heat the temperature adjustment module 8 according to the adjustment signal through the serial communication module 5 and the second serial communication interface 6, such as increasing the temperature heating power by 5% and reducing the cooling power by 10%.

[0038] The main controller 1 is connected to the storage module 11 so as to store the real-time temperature detected by the temperature detection module 4 in the storage module 11 .

[0039] The main controller 1 is connected to the curve generation module 10 to generate a temperature-time curve based on the real-time temperature stored in the storage module, and store it in the storage module 11 , and can also be displayed in real time through the human-computer interaction module 9 .
