Driving warning device used on highway in hazy day and mounting and operation methods of warning device

Abstract

The invention discloses a driving warning device used on a highway in a hazy day comprises a support, a driving warning indicator and a solar cell, wherein the driving warning indicator is provided with an infrared communication module, a laser distance measurement module and an antenna; the infrared communication module is used for communication with an infrared communication handheld console; the laser distance measurement module is used for measuring the driving speed of a vehicle on the highway; and the antenna is used for communication among all driving warning devices. When the driving warning device used on the highway in the hazy day is mounted, the driving warning devices are fixedly arranged on two sides of the highway at equal intervals, and initial parameters of the driving warning devices are set through the infrared communication handheld consoles; and when the driving warning devices used on the highway in the hazy day operate actually, the devices operate in a linkage manner, different forms of indication cursors are formed on the right side of a road according to the distances among vehicles driving on the highway and the speeds, so that drivers are assisted in judging the distances to front and rear vehicles, and rear-end collision accidents easily caused between the vehicle and the front vehicle because of sight blocking by haze are avoided.

Description

technical field [0001] The invention relates to the technical field of safe driving in foggy days on highways, in particular to a warning device for driving in foggy days on highways and an installation and operation method. Background technique [0002] When driving on a foggy day on the expressway, because the line of sight is blocked by the haze, it is impossible to observe the road conditions far ahead when driving, and the distance between the vehicle behind and the vehicle in front is prone to be too close; if the vehicle in front encounters an emergency and brakes suddenly , the rear car will be too close to the front car and the braking distance is insufficient, resulting in a rear-end collision with the front car. Contents of the invention [0003] In order to overcome the deficiencies in the background technology, the present invention discloses a driving warning device in foggy days on expressways, including a bracket, a driving warning device, and a solar cell;...
