Abstract: The invention provides a gas concentration control method and device, a storage medium, and computer equipment. The method comprises the following steps: respectively calculating the first and secondinternal-external air pressure difference theoretical values of a vacuum sealed cavity according to a preset target gas concentration, a filling gas concentration and the obtained internal-external air pressure difference data of the vacuum sealed cavity during the inflation of filling gas and target gas; controlling the inflation of the filling gas and the target gas, so as to enable the internal-external air pressure difference data of the vacuum sealed cavity to reach the first and second internal-external air pressure difference theoretical values. The vacuum sealed cavity is used for avoiding the mixing of other gas. Because the internal-external air pressure difference can be precisely controlled through the inflation of gas, the internal-external air pressure difference theoreticalvalues are obtained through calculation and the inflation quantity of gas is strictly controlled according to the theoretical values. The calculated internal-external air pressure difference theoretical values are reached through the controlling of the inflation of different types of gas, thereby achieving the accurate control of the gas concentration, and obtaining the medium-low-concentration target gas.
