Method for monitoring seismic intensity and judging influence interval of ordinary-speed railway and related equipment thereof

The invention discloses a general-speed railway seismic intensity monitoring and influence interval judging method and related equipment thereof. The method comprises the following steps: acquiring seismic event information of a seismic network; determining whether reported intensity information exists along the ordinary-speed railway in the corresponding area according to the earthquake event information; if not, drawing an intensity distribution diagram according to a preset seismic intensity attenuation relation model; if yes, under the condition that the reported intensity information has an effective instrument intensity value, updating the seismic intensity attenuation relation model by adopting a Kriging interpolation algorithm, and drawing an intensity distribution diagram; and in an influence range formed from the epicenter to a preset distance parameter, determining a mileage interval which intersects with the railway line under the surrounding of different intensity isolines, creating a correspondi
