Dam fire-fighting early warning method based on big data and fire-fighting system

The invention provides a dam fire-fighting early warning method based on big data and a fire-fighting system. The method comprises the following steps: for each region of a dam, detecting whether a parameter of each sensing data in the region is in a corresponding preset range or not by using an edge server; based on the sensing information and local historical information corresponding to the early warning area, obtaining an early warning level and first pre-diagnosis strategy information of the dam; obtaining target pre-diagnosis strategy information according to the first pre-diagnosis strategy information; taking the sensing information as first state information; generating target pre-diagnosis strategy information based on the first pre-diagnosis strategy information and the second pre-diagnosis strategy information; the target pre-diagnosis strategy information is used for being sent to the field user equipment. All areas of the dam are monitored in real time through sensor information in the fire figh
