Problems solved by technology

[0004] Therefore, it is very important to add warnings at the back of the maintenance vehicle. Putting cones in advance or signs of slowing down while working can still remind the vehicles coming from behind, but sometimes we do not see these warning signs, even if there are warning arrows or a warning on the car body. A small warning light, it is still not obvious enough when viewed from a distance during the day

Abstract

The invention discloses a maintenance truck tail anti-collision early-warning system and early-warning method based on millimeter waves, and relates to the field of automobile anti-collision systems.The early warning system comprises a millimeter-wave radar, a center processor, an audible and visual alarm lamp and a anti-collision early-warning display screen. By the aid of a millimeter-wave probing technique, the speed and the distance of a rear vehicle are calculated by the aid of a signal processor, double alarm modes of the anti-collision early-warning display screen and the audible and visual alarm lamp timely and effectively remind the rear vehicle of reducing speed or changing a lane and also remind a driver of a maintenance truck of coming of the rear vehicle, double guarantee cangreatly reduce rear-end collision probability between the rear vehicle and the road maintenance truck, and property and personnel safety of the rear vehicle and the road maintenance truck is improved.

Description

technical field [0001] The invention relates to the field of automobile safety anti-collision systems, in particular to a rear-end anti-collision warning system and an early warning method for maintenance vehicles based on millimeter waves. Background technique: [0002] After nearly ten years of rapid development, by the end of 2010, the total mileage of expressways in China had reached 74,000 kilometers, ranking second in the world after the United States. At present, with the rapid growth of the mileage of expressways in my country and the increase of road service life, my country's expressways have entered a period of equal emphasis on construction and maintenance. More than 10,000 kilometers of expressways built before 2000 have entered the period of overhaul. More than 50,000 kilometers of expressways built in the past have generally entered the normal maintenance period after the defect liability period. The workload is increasing, the technical content is getting high...
