This invention relates to the field of gas composition analysis technology, specifically to a method and terminal for detecting and classifying the composition of explosive hazardous gases. The method includes the following steps: acquiring sensor node tags and sampling data; constructing a composition monitoring sequence; extracting combinations of differential channel tags and time segments; matching a combustible gas composition table with sampling locations; classifying configurational components; mapping channels and time ranges; and obtaining the explosion hazard status identification result. In this invention, a composition distribution chain is constructed by fusing sensor tags and sampling time; the temporal overlap relationship of component combinations is extracted by combining multi-channel data; corresponding segment identifiers are established to complete the identification of the gas's coordinated change structure; a hierarchical association is established through the mapping relationship between tags and a set composition table; structural hierarchy is divided by distinguishing between repeating and non-repeating components; and spatiotemporal continuity mapping is performed by combining distribution trends and channel coverage. This facilitates the location and judgment of the accumulation process of risky components and enhances the response and linkage capabilities to explosion triggers.
