Roads traffic collision early warning device

Abstract

The invention discloses an early-warning device for road traffic conflicts, which comprises a passing vehicle detector, a staying vehicle detector, a pedestrian detector, a data receiving module, a main control module, a forward alarm, a backward alarm, a driving module, a data communications interface, a voice communications and broadcast module, and a power source. An LED array is installed inside the backward alarm, and a light source and a light-gathering part are installed inside the forward alarm. Output terminals of the passing vehicle detector, the staying vehicle detector and the pedestrian detector connect to the data receiving module; the output terminal of the data receiving module connects to the main control module; the main control module connects to the data communications interface; the other end of the data communication interface connects to the voice communications and broadcast module; and the output terminal of the main control module, via the driving circuit, connects to the forward alarm and backward alarm. The invention provides the multiple early-warning information preventing conflicts to the traffic participants in the region of low visibility and traffic blind spot with the advantages of a good effect in warning and a wide application.

Description

technical field [0001] The invention relates to a road traffic conflict early warning device, in particular to an active road traffic conflict early warning device used to prevent road traffic participants from conflicting with each other. Background technique [0002] Accidents in road traffic are usually caused by traffic participants not being able to detect possible conflict points in time before the accident. Rear-end collision with the vehicle in front; In the "black spot" area where accidents often occur on urban roads, traffic participants cannot find each other in time and take effective measures due to various reasons, resulting in accidents. [0003] All measures and technologies in the field of transportation are developed around the theme of reducing accidents and ensuring smooth traffic, such as traffic regulations, traffic lights, various signs and markings, etc., whose main function is to regulate road traffic participants and reduce accidents .

AI Technical Summary

Problems solved by technology

This kind of early warning device has only one warning method, single function and limited application occasions

[0005] Usually, when the early warning information directly related to the event has a direct and effective early warning effect on the traffic participants, such as the on-site command of the traffic police, the traffic participants can witness the obstacles ahead, etc.; while the permanent, unrelated event A single early warning signal is often ignored by traffic participants. At present, there is no existing technology that can give effective warnings of possible conflicts in advance before traffic participants may conflict.
