Intelligent wireless early warning device for highway tunnel traffic based on Doppler automatic detector

Abstract

Provided is a road tunnel traffic intelligent wireless early warning apparatus based on a doppler automatic detector. The road tunnel traffic intelligent wireless early warning apparatus based on a doppler automatic detector comprises a doppler automatic detector, a doppler data processing analyzer, a WSN wireless sensing network module, and a centralized controller. The doppler automatic detector monitors moving objects in an tunnel in a real-time manner. The doppler data processing analyzer is separately connected to the doppler automatic detector and the WSN wireless sensing network module. The doppler data processing analyzer reads traffic information data provided by the doppler automatic detector in a real-time manner, processes the data according to corresponding rules, and then transmits the data to the centralized controller through the WSN wireless sensing network module in a remote transmission mode. The road tunnel traffic intelligent wireless early warning apparatus based on the doppler automatic detector of the invention can exchange information inside and outside the tunnel timely. Once an accident occurs in the tunnel, the system apparatus will send out an early warning to drivers behind and an alert as soon as possible, vehicles are prevented from entering a tunnel entrance, secondary accidents are prevented from happening, and operations such as personnel rescue, accident handling, site cleaning and tunnel restoration can be accelerated.

Description

technical field [0001] The invention belongs to the technical field of traffic intelligent wireless early warning, in particular to an intelligent wireless early warning device for road tunnel traffic based on a Doppler automatic detector. Background technique [0002] With the development of highway construction in our country, the number of long tunnels and extra-long tunnels is increasing, especially the operation safety of tunnel groups has been clearly placed in front of the operation managers. The safety management of the tunnel group focuses on fire safety and traffic safety, avoiding secondary accidents in the tunnels, ensuring the safety of passing drivers and passengers, and reducing national property losses. Most of the tunnels in our country are located in the area of ​​mountains, hills and ravines. The tunnel space is relatively narrow, the line of sight is limited, and it is difficult to escape, which makes the tunnel a high accident rate area. When serious ac...

AI Technical Summary

Problems solved by technology

When serious accidents (such as explosion of dangerous goods, spontaneous combustion of vehicles, rear-end rear-end collision of vehicles) occur in the tunnel group, especially when the communication cable in the tunnel is blown off, due to the failure of timely communication of information inside and outside the tunnel, the tunnel entrance did not stop the vehicle from passing in time, As a result, follow-up vehicles continue to enter the accident tunnel in a short period of time. On the one hand, it may cause secondary accidents. for difficulty

In the traditional early warning and alarm mode, the traffic police cannot immediately lock the specific location. Especially for highway sections with many tunnels, it is relatively cumbersome to verify the accident and dispatch the police force. Timely alert the driver behind, it is very easy to cause the rear vehicle to rear-end in the tunnel due to the unknown situation ahead, resulting in a secondary accident
