And S33, determining a temperature difference coefficient according to the average temperature difference value and the current time temperature difference value.
Specifically, the temperature difference coefficient can be obtained by calculating the formula two.
The formula II is as follows: temperature difference coefficient is equal to the current time temperature difference/average temperature difference
And S4, determining the released cold quantity corresponding to the cold storage box at the current time according to the unit time cold release quantity, the initial time, the current time and the temperature difference coefficient.
Specifically, the released cold quantity corresponding to the current moment can be obtained through calculation based on the formula III.
