[0026] A sweet potato storage device includes: a storage warehouse and a distributed temperature control device installed in the storage warehouse;
[0027] Distributed temperature control refers to setting up multiple temperature control nodes within a region, which communicate with each other to control the temperature of all nodes within that region. This method can effectively address the problem of uneven temperature distribution across multiple regions and allows for personalized temperature control in different areas.
[0028] In one embodiment, such as Figure 1 As shown, the distributed temperature control device consists of several temperature detection modules. Each temperature detection module has the same result and is connected in series. Each temperature detection module is equipped with a power adapter and connected to a power source. Each temperature detection module is connected to a CAN bus.
[0029] In one embodiment, such as Figure 2 As shown, the temperature detection module consists of a processor, and a power supply circuit, an address encoding circuit, a temperature sensor input circuit, a CAN communication circuit, and a display driver circuit connected to the processor.
[0030] In one embodiment, such as Figure 2 As shown, the input terminal of the power module is connected to the power adapter, and the output terminal is connected to the processor.
[0031] In one embodiment, such as Figure 2 As shown, the address encoding circuit is composed of encoding switches.
[0032] In one embodiment, such as Figure 2 As shown, the temperature sensor input circuit consists of a temperature sensor and a processing circuit. The temperature sensor is installed inside the storage room, and the input terminal of the processing circuit is connected to the temperature sensor, while the output terminal is connected to the processor.

[0036] Working Principle: A 240V power input is provided, powered by an AC 220V / DC 24V power adapter for each temperature detection module. The power circuit within each module converts this power to 5V and 3.3V outputs. Each module sends its detected and calculated temperature data to the CAN bus and receives temperature data from other modules. The processor is based on an STM32F1 series ARM chip. In the address encoding circuit, the negative signal of the 3.3V power supply is input to the chip's GPIO input pin via an encoding switch. In the temperature sensor input circuit, the temperature sensor collects the temperature, and the output signal, after processing, is input to the chip's GPIO input pin. The ARM chip processes and calculates the input temperature signal to obtain the temperature value. The CAN pin communicates with a CAN transceiver, which is also connected to a terminal block. The GPIO output pins connect to the display driver circuit's monitor and the temperature control device, driving the monitor to display the temperature value and the temperature control device to adjust the temperature. The ARM chip sends the detected temperature data to other temperature detection modules via the CAN bus.
