Method for performing automatic alarming on condition of agglomerate fog on highway

Abstract

The invention relates to an alarming method, and particularly to a method for performing automatic alarming on condition of agglomerate fog on a highway. The method is used for automatically monitoring and performing early-warning and warning on the agglomerate fog based on interaction among a lever bracket, an emitter of an opposite-type photoelectric switch, a receiver of the opposite-type photoelectric switch, an alarm device, a solar cell and a highway monitoring network. The method can remind a driver in driving a vehicle of advanced speed reduction and driving into the agglomerate fog inlow speed and furthermore realizes in-time switching-on of a vehicle alarming lamp for reducing and preventing traffic accidents caused by the agglomerate fog.

Description

technical field [0001] The invention relates to an alarm method, in particular to an automatic alarm method for expressway cloud fog. Background technique [0002] Fog is the number one killer on the expressway, which can easily lead to rear-end collisions of vehicles. In order to cope with the cloudy fog, the real-time monitoring and early warning system for highway cloudy fog with the publication number CN101694748A sends the visibility information to the road display screen and the driver's mobile phone with a radio module. The driver cannot get the visibility information near the front in time, so the vehicle will still break into the fog at high speed, which will easily lead to accidents. Public number CN103413442A expressway fog early warning system and early warning method based on line-of-sight distance detection is to set up fog detection devices on both sides of the expressway, that is, to set corresponding laser emitting modules on both sides of the expressway A...

In order to cope with the cloudy fog, the real-time monitoring and early warning system for highway cloudy fog with the publication number CN101694748A sends the visibility information to the road display screen and the driver's mobile phone with a radio module. The driver cannot get the visibility information near the front in time, so the vehicle will still break into the fog at high speed, which will easily lead to accidents

Public number CN103413442A expressway fog early warning system and early warning method based on line-of-sight distance detection is to set up fog detection devices on both sides of the expressway, that is, to set corresponding laser emitting modules on both sides of the expressway And the laser receiving module, because the device is installed in the horizontal direction of the highway, and the height of the vehicles driving on the highway is 4-5 meters, so the laser transmitting module and receiving module are installed above 5 meters on the road surface Because the advection type fog is sometimes below 5 meters from the ground, the detection module cannot detect the advection type fog within 5 meters from the ground, so the system and method are easy to leak when detecting the fog And inaccurate, it is still impossible to automatically, accurately and timely forecast group fog warning information to drivers upstream of the expressway in advance
