[0002] The cold chain is an important part of transportation and plays an important role in the transportation of food, medicine, etc. The existing cold chain mainly includes an inverter refrigerator installed on the top of the carriage, and a control panel installed in the cab. The control panel It is electrically connected with the frequency conversion refrigerating machine, and a pipeline connected with the air outlet of the frequency conversion refrigerating machine is arranged in the compartment, and the air outlet of the pipeline points to the interior of the compartment, and the inner wall of the compartment is provided with a thermal insulation board, and the inner wall of the compartment is provided with a fixed temperature and humidity sensor. The humidity sensor is electrically connected to the control panel. During use, since the temperature and humidity sensor is fixed at the edge of the compartment, it cannot detect the middle position of the compartment well, and the detection accuracy is poor, resulting in the temperature and humidity control of the cold chain temperature and humidity control system. Poor capacity, affecting cold chain transportation capacity
