Underground production safety early warning method, system and equipment based on gas monitoring

The invention discloses an underground production safety early warning method, system and equipment based on gas monitoring, and aims to solve the technical problems that existing underground production safety early warning is not timely and the actual effect is poor. The method comprises the following steps: acquiring concentration data of harmful gas under a mine in real time; calculating the concentration rising rate of the harmful gas; on the basis of the concentration rising rate of the harmful gas, predicting the probability of a safety accident of the mine; and if the probability of the occurrence of the safety accident exceeds a preset threshold value, generating an early warning signal, and respectively transmitting the early warning signal to an acousto-optic early warning mechanism and terminal equipment of a central control room. A gas sensor array is erected under a mine, the concentration change rate of harmful gas under the mine is monitored in real time, the concentration change of hazardous g
