Method for controlling gas in dustproof bin and related device

The invention discloses a gas control method in a dustproof bin and a related device, and the method comprises the steps: calculating the first gas concentration at a working position at the current moment under the condition of considering the distance from a first gas sensor to the working position; under the condition that the time interval from starting of the fresh air circulation equipment to influencing the gas concentration of the working position, the first gas concentration of the working position at the current moment and the number of workers of the working position are considered, the first gas concentration prediction model is adopted to predict the first gas concentration of the working position at the future moment; according to the method, the first gas concentration of the working position at the moment t1 + t2 + t is predicted, and the fresh air circulation equipment is controlled in advance according to the prediction result, so that danger caused by real-time monitoring and action delay o
