Problems solved by technology

[0004] Due to the rapid occurrence of waterlogging and the ferocious onslaught, the monitoring data cannot be sent to the citizens in a timely and rapid manner. It has not been developed in depth according to the daily needs of the citizens, and cannot provide satisfactory services to the citizens. The system functions need to be improved

Abstract

The invention discloses a navigation method and device based on real-time internal waterlogging data, and relates to the technical field of navigation. The method includes the steps: acquiring start point information and end point information inputted by a user; calculating all feasible paths from a start point to an end point by a navigation system according to the start point information and the end point information inputted by the user to generate a path list; dividing all the feasible paths in the path list according to road segments; acquiring water depth information of each road segment; acquiring an internal waterlogging coefficient of each road segment according to the water depth information of each road segment; calculating the sum of internal waterlogging coefficients of each feasible path according to the internal waterlogging coefficient of each road segment; taking minimum sum of the internal waterlogging coefficients among the sums of the internal waterlogging coefficients of the feasible paths as a navigation path, and transmitting the navigation path to the user. The navigation method can effectively navigate effective road segments when internal waterlogging happens, internal waterlogging road segments are avoided, and people can conveniently go out.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a navigation method and device based on real-time waterlogging data. Background technique [0002] In recent years, frequent waterlogging disasters have caused serious obstruction or even paralysis of urban traffic, and huge losses of national and public property. Waterlogging has become one of the problems that seriously plague urban development. Although the government has invested hundreds of millions of dollars to control the urban waterlogging problem by transforming the drainage pipe network and other methods, due to the complex causes of waterlogging and the long implementation time of engineering measures, it is difficult to immediately show the effect of waterlogging, and the waterlogging problem still seriously affects people daily life of the general public. [0003] At present, the waterlogging monitoring system that the government has built is mainly used to issu...
