A cross-wind early warning method for cars passing on highway bridges

Abstract

The invention discloses a cross-wind early-warning method for cars when passing on highway bridges, and belongs to the field of traffic early-warning. A cross-wind early warning method for a car when passing on a highway bridge. The method is realized based on a cross-wind early-warning device for a highway bridge. The cross-wind early-warning device for a highway bridge includes a cabinet, and a cavity is provided at the upper end of the front wall of the cabinet. A fixed shaft is fixed, a connecting rod is sleeved in the middle of the fixed shaft, a windward plate is fixed on the upper end of the connecting rod, a through groove A is opened in the middle of the bottom surface of the cavity, and a rocker is hinged on the rear side of the through groove A through the plate shaft. Two supporting plates are fixed symmetrically at the ends, a fixing seat is arranged under the supporting plates, a restoring spring is fixed between the supporting plates and the fixing seat, and a warning component is arranged on the rear side of the top surface of the box body. The invention can enable the highway management department to perform self-prediction on the early warning of the cross wind without the weather forecast, greatly improves the flexibility of judging the strength of the cross wind, has strong practicability, and is worthy of popularization.

Description

technical field [0001] The invention relates to the field of traffic early warning, and more particularly, to a cross-wind early warning method for cars passing on highway bridges. Background technique [0002] According to highway traffic accident data, bad weather is an important cause of road traffic accidents, especially when passing highway bridges. It is very easy to cause the vehicle to skid under the crosswind. If the driver enters an area with strong crosswind without any prediction, because the vehicle speed is not lifted to reduce it, it is easy to cause the vehicle to have a large crosswind. It will cause extremely serious traffic accidents, which will greatly threaten the life safety of drivers and passengers. The patent with the prior art publication number CN201710384067.3 provides a blowing cross-wind warning device , the device has the following problems: 1. The device only judges the magnitude of the wind force by folding and hiding the wind direction warn...

AI Technical Summary

Problems solved by technology

[0002] According to the highway traffic accident data, severe weather is an important cause of road traffic accidents, especially when passing through highway bridges, when the lateral wind force is strong, the wind area on the side of the vehicle is large, so It is very easy to cause the vehicle to skid under the blowing of the cross wind. If the driver enters an area with strong cross wind without warning, the vehicle will easily cause a large lateral slip because the speed of the vehicle is not raised to reduce. Move, and then it will cause extremely serious traffic accidents, which will greatly threaten the life safety of drivers and passengers. The patent of the prior art publication No. CN201710384067.3 provides a blowing type cross wind warning device , the device has the following problems; 1, the device only judges the size of the wind force by folding and hiding the wind direction warning map, it cannot effectively detect the specific wind force of the crosswind, and its practicability is poor; 2, the device is used in When the cross wind force reaches the level of early warning, it only warns through the expansion of the wind direction warning map, which is difficult to attract the driver's attention, and the early warning ability is weak; The method of broadcasting early warning information on the subtitle screen at the key node of the road not only has a low degree of warning, but also cannot accurately forecast for different geographical locations, and has low flexibility. In addition, in seasons when the weather conditions are changeable , the accuracy of weather forecast will also be reduced, and the timeliness will also be reduced, so it is easy to cause the problem of untimely early warning. In view of this, we propose a cross wind early warning method for cars passing on highway bridges
