Problems solved by technology

However, even with the warning road signs marked, accidents often occur near expressway tunnels. The driver cannot adapt to the environment for a while, and there will be a short-term blurred vision, which can easily lead to accidents

Embodiment 1

[0061] A tunnel warning system, including a tunnel body 1, also includes:

[0062] The acquisition sensor module 2 collects the flame or smoke characteristics in the tunnel body 1;

[0063] The image / video module 3 records and / or takes pictures of the environmental state in the tunnel body 1;

[0064] The signal transmission module 4 communicates with the acquisition sensor module 2 and the image / video module 3, receives the acquisition information of the acquisition sensor module 2 and the image / video module 3 and uploads the acquisition information to the control module;

[0065] The control module 5 communicates with the signal transmission module 4, receives and processes the collected information sent by the signal transmission module 4 and sends out a control signal for controlling the laser warning device to generate a laser light curtain after processing;

[0066] The laser warning device 6 is communicated with the control module 5, responds immediately after receivin...

Embodiment 2

[0068] On the basis of the above-mentioned embodiment 1, further improvements are made to it, and there are two ways to realize the formation of a laser light curtain at the tunnel entrance:

[0069] One, when the first laser emitter 61 is arranged on the top of the tunnel entrance of the tunnel body 1, the nozzle of the first water mist spray head 624 is also arranged at the entrance of the tunnel body 1. The hole is evenly arranged along the contour of the tunnel body 1, and the nozzle of the first water mist spray head 624 is located in front of the first laser emitter 61 and simultaneously projects laser light and water mist to the tunnel entrance to achieve contact between the two.

[0070] Second, when the first laser emitter 61 is installed obliquely on the top of the tunnel entrance of the tunnel body 1, the nozzle of the first water mist nozzle 624 is inclined along the tunnel entrance. Arrange upward evenly to realize the contact between laser and water mist.

Embodiment 3

[0072] On the basis of the above-mentioned embodiment 2, it is further improved to realize the formation of a laser light curtain at the tunnel entrance: a fixing frame 15 is set near the front of the tunnel body 1, and the first laser emitter 61 is installed on the When on the fixed frame 15, the first laser emitter 61 is obliquely fixed on the fixed frame 15 and the nozzles of the first water mist spray head 624 are evenly arranged obliquely upward along the wall at the entrance of the tunnel, and The first laser emitter 61 is arranged opposite to the nozzle of the first water mist spray head 624, thereby realizing the contact between the laser and the water mist.

Abstract

The invention provides a tunnel warning system. The tunnel warning system comprises a tunnel body, a collection sensor module, an image / video module, a signal transmission module, a control module anda laser warning device. The laser warning device comprises a first laser launching device and a water mist spraying device. By collecting flame and smoke features in the tunnel body and monitoring pictures in a tunnel after treatment of the control module and accidents occurring in the tunnel body, the control module is used for controlling a first laser launcher to project a laser and controlling the water mist spraying device to spray water mist, through the combination of the laser and the water mist, and a shining warning laser light curtain with a larger area is formed at a tunnel entrance; and in addition, according to the tunnel warning system, corrugated plate guardrails on two sides of the tunnel are brightened, a road marking is brightened, a road indication sign is brightened and a contour shape of the tunnel body is brightened, therefore, enough brightness is furthest ensured for driving personnel during entering the tunnel, and the occurrence of the accidents is greatly reduced.

Description

technical field [0001] The invention relates to the traffic field, in particular to a tunnel warning system. Background technique [0002] At present, with the rapid development of China's economy, considerable attention has been paid to the improvement of road traffic, which is reflected in the laying and popularization of expressways. Expressway is a high-grade kilometer, generally designed for a speed of 120 km / h or higher. The road surface includes four or more lanes, with a divider in the middle and guardrails on both sides. [0003] Since the vehicles on the expressway must keep running at a high speed, the safety of the road conditions is very important for the driving of the vehicles. Due to the complex environment of the expressway, there are often tunnels. When vehicles drive into the tunnel during the day, due to the large difference in light intensity inside and outside the tunnel, a series of visual problems will occur. Therefore, in the vicinity of each tunnel...
