Laser auxiliary warning device of automobile in severe weather

Abstract

The invention discloses a laser auxiliary warning device of an automobile in severe weather. The laser auxiliary warning device comprises a red laser device, a circuit control system and an optical shaping system. The red laser device can generate red light with a preset wavelength; the circuit control system is connected with a driving circuit of the red laser device, and the red laser device can output the red light under the control of the circuit control system; the optical shaping system comprises an optical lens assembly, is configured at a transmission window of the red laser device and outputs the emergent laser light after shaping the laser light. The laser auxiliary warning device has the advantage that a good instruction effect can be realized under the severe weather condition.

Description

technical field [0001] The invention relates to a laser warning system, which is used for warning vehicles under severe weather conditions. Background technique [0002] According to data, the traffic accidents caused by bad weather such as dense fog account for more than 1 / 4 of the total number of accidents. The heavy fog weather on the expressway is a big killer of traffic accidents, which has caused great losses to the country and people's lives and properties. The main hazard of dense fog is that it reduces visibility, and the driver cannot accurately judge the speed of the vehicle in front and the distance to the vehicle in front when in the foggy area. [0003] In order to reduce the occurrence of rear-end collisions due to the impact of dense fog and other bad weather, from January 1, 1999, the Ministry of Public Security required that motor vehicles must be equipped with fog lights that meet the national standards, and motor vehicles that did not install rear fog li...

Problems solved by technology

[0005] At the same time, when the car breaks down on the road, it is necessary to place the tripod near the car to remind the next car. However, if it encounters rain, snow, fog or driving at night, placing the tripod manually is prone to secondary accidents.

[0006] The laser light intensity is relatively strong, so it has been widely used in the field of assisted driving, but the use of laser auxiliary devices in the field of laser assisted driving is relatively complicated, such as using lasers for distance measurement to avoid rear-end collisions

Other methods are to configure active lasers, use reflection to detect vehicles coming from the rear, and then use warning devices, such as loudspeakers, to warn rear vehicles to avoid rear-end collisions. This kind of warning device is relatively complicated to implement, high in cost, and often does not work. very big
