checking the temperature inside the current independent storage bin (7) through a touch display (19), and adjusting the temperature through the touch display (19) according to the temperature required to be stored by the sample;
step three, after adjustment is carried out through the touch display (19), the feedback circuit (24) converts information and then transmits the information to the single chip microcomputer (21), the single chip microcomputer (21) reads received data, and the numerical difference between the current temperature environment and the adjusted temperature is calculated;
and step four, the calculated numerical difference is transmitted to a current control circuit (26), the current control circuit (26) adjusts the current of the system, and the temperature control circuit (27) finally converts the current into a temperature numerical value.
