Multi-category fire early warning data distributed training and local fire extinguishing method and system

The invention relates to a multi-category fire early warning data distributed training and local fire extinguishing method. The method comprises the steps that a main detector collects data when a fire occurs; the fire-fighting controller wirelessly transmits the data to the edge server, establishes a fire behavior judgment model on the edge server and performs distributed training; when the edge server does not obtain a trained fire behavior judgment model, the fire fighting controller judges a fire behavior through a fire behavior judgment threshold table, opens a control valve of a nozzle by taking an ignition point detected by a main detector as a circle center, and sends fire behavior judgment parameters to surrounding detectors; when the edge server obtains a trained fire judgment model, fire judgment is carried out on all the detectors and the edge server according to the optimal segmentation point, and fire judgment parameters are obtained. The invention further discloses a multi-class fire early warn
