Safe early warning system of road and method

Abstract

The invention relates to a safe early warning system of a road and a method. The system comprises a first infrared pyroelectric module, a second infrared pyroelectric module, a first Bluetooth module, a second Bluetooth module, a first handheld terminal and a second handheld terminal. The first handheld terminal is arranged on a running vehicle in a running direction on a turning road. The second handheld terminal is arranged on a running vehicle in another running direction on a turning road. The first infrared pyroelectric module is connected with the first Bluetooth module through a circuit. The second infrared pyroelectric module is connected with the second Bluetooth module through a circuit. The first Bluetooth module is connected with the second Bluetooth module through a circuit and wirelessly connected with the first handheld terminal. The second Bluetooth module is wirelessly connected with the second handheld terminal. Compared with the prior art, the system is characterized in that drivers in two running directions of the turning road are prompted to make early warning preparation, so occurrence of traffic accidents in dangerous road sections is reduced as far as possible, and an objective of safe driving is achieved.

Description

technical field [0001] The invention relates to the technical field of safety early warning, in particular to a safety early warning system and method for pedestrians and vehicles on dangerous roads. Background technique [0002] Cars are an indispensable means of transportation for modern people to travel and transport goods. With the continuous improvement of people's living standards in our country, more and more people buy and drive vehicles, and there are more and more vehicles on the road. The number of traffic accidents The probability also increases. Some special road sections, such as sharp turning sections on mountainous roads, S-shaped roads, etc., are frequent road sections of major traffic accidents, which cause more casualties and huge economic losses every year. It is particularly important to carry out active warning on road sections to reduce losses. [0003] At present, there are many studies on driving safety at home and abroad. At present, there are aut...

Problems solved by technology

These technologies are very complicated and cost very high. Such technologies are too expensive to invest in areas with underdeveloped economies and limited road construction funds.

In the low-cost field, there is currently only a way to install a convex mirror for early warning, but the effect of this method is very limited, and the convex mirror cannot play its role in rainy or snowy weather.

[0004] The results of foreign research mainly include: (1) lane departure system, which assists the driver to reduce traffic accidents due to lane departure by means of an alarm, but the reliability of the system is affected by weather conditions and illuminance; (2) Blind spot monitoring system, the system assists the driver to avoid obstacles in time by installing sensors on the vehicle to detect the surrounding environment, but the detection distance of the sensors is very limited, and for high-speed vehicles, even if obstacles are found, it is too late to control the vehicle to avoid them

[0005] These research results are not suitable for safety warning prompts on roads with frequent traffic accidents such as S-shaped roads and sharp turns on mountain roads.
