Gas leakage alarm safety analysis method

The invention relates to the technical field of fuel gas leakage safety analysis, in particular to a fuel gas leakage alarm safety analysis method, which comprises the following steps of: firstly, obtaining hazard indexes of fuel gas and a corresponding hazard index sequence according to real-time input flow, real-time output flow and flame heat of the collected fuel gas; obtaining an approximation degree between the hazard index sequences of different gas pressures, and grouping the different gas pressures to obtain a plurality of clusters; calculating a fluctuation mean value of each flame heat sequence of each cluster; obtaining the total maximum heat in the flame heat sequence of each cluster and the hazard mean value of the hazard index sequence; obtaining an alarm index according to the total maximum popularity, the fluctuation mean value and the hazard mean value; and performing early warning according to the alarm index. According to the method, the alarm index is obtained by analyzing the danger degr
