[0002] Due to the limitations of early urban planning, the drainage performance of most road sections is poor. In recent years, with the frequent occurrence of natural disasters, heavy rains will cause urban waterlogging. However, there is no effective method in the existing technology to automatically detect the occurrence of waterlogging. Road sections require manual detection, which is time-consuming and labor-intensive. In addition, due to the untimely detection of waterlogging, large-scale traffic congestion incidents on the urban road network have occurred, and serious economic and property losses have also been caused.

Embodiment 1
[0068] The invention provides a method for detecting urban waterlogging based on floating car technology, comprising the following steps:
[0071] Collect floating car data in real time; the floating car data includes vehicle number, data upload time point, geographic coordinates, instantaneous speed and driving azimuth; the driving azimuth is the angle between the direction of the front of the vehicle and a preset reference direction.
[0072] S2: Determine whether the current weather is rainstorm weather, if so, execute step S3;
[0073] The S2 is specifically:
[0074] A measuring cylinder is preset, and the measuring cylinder is set in an open place in the city; a water level sensor is arranged in the measuring cylinder;
[0076] According to the water level value obtained in real time, the water level increase value at ...

Abstract
The present invention provides an urban waterlogging detection method based on floating car technology and a terminal. The method includes the following steps: S1: collecting floating car data; S2: judging whether the current weather is rainstorm weather, and if so, performing step S3; The floating car data, through data analysis, obtains all urban road sections where the reduction in traffic flow in the preset first time is greater than the preset traffic flow threshold and the number of U-turn vehicles is greater than the preset vehicle number threshold; S4: According to the Road section, get the list of urban flooded road sections. The invention can timely and effectively judge the waterlogged road section, so as to give early warning to the waterlogged road section in time, prevent other vehicles from driving to the waterlogged road section, effectively alleviate traffic congestion, and reduce economic and property losses.
Description
technical field [0001] The invention relates to the technical field of waterlogging detection, in particular to an urban waterlogging detection method based on floating vehicle technology and a terminal. Background technique [0002] Due to the limitations of early urban planning, the drainage performance of most road sections is poor. In recent years, with the frequent occurrence of natural disasters, heavy rains will cause urban waterlogging. However, there is no effective method in the existing technology to automatically detect the occurrence of waterlogging. Road sections need to be manually detected, not to mention time-consuming and labor-intensive. Untimely detection of waterlogging will lead to large-scale traffic congestion on the urban road network and cause serious economic and property losses. Contents of the invention [0003] The technical problem to be solved by the present invention is: the present invention provides an urban waterlogging detection method ...
