(1) if the continuous rainfall reaches 30-70mm/12h or 50-100mm/24h, then 1-level blue rainstorm early warning is performed;
(2) when the continuous rainfall reaches 70-140mm/12h or 100-200mm/24h, the early warning is 2-level yellow heavy rainstorm;
(3) and when the continuous rainfall reaches more than 140mm/12h or more than 200mm/24h, 3-grade extra-large heavy rain orange early warning is carried out.
10. The early warning method of the emergency early warning system for urban traffic rainstorm according to claim 8, wherein: in the step S2, the rescue operation path optimization scheme adopts Dijkstra algorithm, and specifically includes the following steps:
step one, giving RsMarked with P, P (R)s) Each remaining point is given the designation T, T (R)i)＝+∞；
Step two, if RiPoint just after P designation, consider such point Rj，(Ri，Rj) Is of E, and RjIs marked by T, to RjThe T index of (a) is modified as follows:
T(Rj)＝min[T(Rj),P(Ri)+Iij]；
step three, comparing all points with T labels, and changing the minimum point to the P label, namely P (Ri) min [ T (Ri) ];
when more than two minimum points are simultaneously changed into P marks, stopping if all the points are the P marks;
wherein T represents a group RsStarting from RiIs a temporary label; p represents a group selected from RsStarting from RiThe estimated shortest road weight is a permanent label; r represents the vertex of the graph; e represents an edge of the graph; i represents the way weight value.
