Warning system for preventing secondary traffic accident on highways

Abstract

The invention discloses a warning system for preventing a secondary traffic accident on highways. The warning system comprises a plurality of warning units and a host computer, wherein the warning units are distributed on a highway needing to be warned from front to back in the driving direction, the host computer is used for starting all the warning units behind the traffic accident occurrence site, and all the warning units are controlled by the host computer which is positioned on a remote monitoring center. Each warning unit is composed of a warning device, a trigger start device for starting the warning unit and a power supply device for supplying power for the warning device and the trigger start device. Each trigger start device is composed of a monitoring device for real-time monitoring whether traffic accident happens within the section of highway needing to be warned and a controller for analyzing monitoring results and controlling the warning device, and the controller is connected with the host computer. The warning system for preventing the secondary traffic accident on highways has the advantages that design is reasonable, installment and layout are convenient, operation is easy, use effect is good, and secondary traffic accident rate on highways are decreased effectively.

Description

technical field [0001] The invention relates to a warning system, in particular to a warning system for preventing secondary traffic accidents on expressways. Background technique [0002] Secondary traffic accidents refer to re-accidents caused by failure to warn in time, improper warning measures, and unsatisfactory warning effects due to the negligence of the parties or rescuers on the basis of the original traffic accident. [0003] Secondary traffic accidents are a common phenomenon of highway traffic accidents in my country at present, and they are also typical forms of serious traffic accidents such as mass death and mass injury and vehicle damage. Compared with the first accident, the second traffic accident often causes more damage and causes more serious personal and property losses, which will greatly increase the difficulty of further rescue work, so the second traffic accident is an accident that needs to be prevented as much as possible. Therefore, the prevent...

AI Technical Summary

Problems solved by technology

In actual use, the above three accident warning measures all have certain defects, which are embodied in the following aspects: after the accident, the drivers and passengers were either killed or injured, panicked, and could not report to the police in time and accurately; the monitoring system has a certain degree of monitoring Angle and monitoring range, there are monitoring blind spots; the layout position of the variable information board is relatively fixed, and because of the high cost, the interval is often long, so the continuity is poor; the warning distance of the double flashing warning light and the vehicle-mounted folding warning sign is limited, and the vehicle-mounted folding The area of ​​the type warning sign is small, the placement distance is relatively close, the height is low, and there is no continuity, and the warning effect is very poor;

It can be seen that the above-mentioned existing accident warning measures have defects such as untimely warning and poor warning effect.

[0006] To sum up, in view of the fact that when an accidental failure or traffic accident occurs to the vehicle ahead on the expressway, the drivers and passengers are generally in a state of panic, and often forget to send warning information to the following vehicles, fail to warn in time, have improper warning measures, and have poor warning effects, etc. Secondary traffic accidents are caused by subsequent vehicles failing to take appropriate measures in time, especially in low visibility conditions such as smog, and secondary traffic accidents on expressways are more frequent
