In step 104, suspicious elimination is performed on each gas flow suspicious characteristic value, so as to obtain a plurality of gas flow characteristic values, and a gas flow characteristic total value is determined according to all the gas flow characteristic values.
In some embodiments, the suspicious characteristic value of each gas flow is removed, so as to obtain a plurality of gas flow characteristic values, which can be realized by the following steps:

wherein T represents a total gas flow characteristic value, T a represents an a-th gas flow characteristic value, a represents a total number of gas flow characteristic values, a=1, 2.
The total value of the gas flow characteristics in the application is a parameter value indicating the closing degree of the closed position of the refrigerator, and the greater the total value of the gas flow characteristics is, the smaller the closing degree of the closed position of the refrigerator is.
In step 105, an alarm signal is sent to the user when the gas flow characteristic total value exceeds a preset gas flow characteristic threshold.
According to the method, the closing degree of the closed position of the refrigerated cabinet corresponding to the total gas flow characteristic value can be determined according to historical experimental data, forty percent of the average value of the total gas flow characteristic values is selected as a gas flow characteristic threshold value, the gas flow characteristic threshold value is adjusted according to actual conditions, the gas flow characteristic threshold value is used as a critical value of closing tightness of the closed position of the refrigerated cabinet, when the total gas flow characteristic value is lower than the gas flow characteristic threshold value, the closed state of the closed position of the refrigerated cabinet is indicated to be tight, when the total gas flow characteristic value exceeds the gas flow characteristic threshold value, the closed state of the closed position of the refrigerated cabinet is indicated to be loose, when the total gas flow characteristic value is 0, the closed position of the refrigerated cabinet is indicated to be completely closed, in addition, when the total gas flow characteristic value is smaller than the preset gas flow characteristic threshold value, an early warning signal can be sent to a user for early warning, and when the method is specifically implemented, the color of a Light Emitting Diode (LED) lamp emitting an early warning signal is set to be yellow, and the color of the LED lamp emitting the warning signal is set to be red, and the color of the early warning signal is not repeated herein.
