Embodiment 1

[0033] like figure 1 As shown in the figure, the whole driving monitoring system in the tunnel includes a card issuing device 1, a card receiving device 2 and an electronic card 3. The card issuing device 1 and the card receiving device 2 are embedded in the lane, and the card issuing device 1 and the card receiving device 2 are within 10mm above the ground. .

[0034] like figure 2 As shown, the card issuing device 1 is arranged in the middle of each lane 5 at the entrance of the tunnel 4. The card issuing device 1 includes a card issuing casing 11, and a camera 111 is provided on the side of the card issuing casing 11 facing the vehicle approaching direction. A distance sensor 112 is arranged at one end close to the camera 111, the camera 111 is used to record the license plate number of the passing vehicle, and the distance sensor 112 is used to detect the chassis height of the passing vehicle; the upper surface of the card issuing housing 11 is provided with a card issui...

Embodiment 2

[0052] like figure 1 As shown in the figure, the whole driving monitoring system in the tunnel includes a card issuing device 1, a card receiving device 2 and an electronic card 3. The card issuing device 1 and the card receiving device 2 are embedded in the lane, and the card issuing device 1 and the card receiving device 2 are within 10mm above the ground. .

[0053] like figure 2 As shown, the card issuing device 1 is arranged in the middle of each lane 5 at the entrance of the tunnel 4. The card issuing device 1 includes a card issuing casing 11, and a camera 111 is provided on the side of the card issuing casing 11 facing the vehicle approaching direction. A distance sensor 112 is arranged at one end close to the camera 111, the camera 111 is used to record the license plate number of the passing vehicle, and the distance sensor 112 is used to detect the chassis height of the passing vehicle; the upper surface of the card-issuing casing 11 is provided with a card-issuin...

Abstract

The invention provides a whole-process monitoring method for driving in a tunnel, which includes: a vehicle selects a lane of the tunnel to enter the tunnel; the vehicle enters the tunnel and drives over the card issuing device; the card dialing mechanism in the card issuing host transmits an electronic card to the card tray in advance The camera records the license plate number of the passing vehicle, and the distance sensor detects the height of the vehicle chassis; the first lifting mechanism in the card issuing host quickly pushes the card tray and the electronic card to the corresponding height; the electromagnet in the electronic card starts to work, and then the electronic card is adsorbed On the chassis of the vehicle; the electronic card follows the vehicle through the entire tunnel, and collects the moving speed and trajectory of the vehicle; passing over the card receiving device, the reader in the electronic card reads the electronic label set on the card receiving device, thereby Trigger the electromagnet to stop working; the electronic card is separated from the vehicle and dropped into the card receiving host; compared with the traditional fixed-point capture method, the whole process of monitoring is realized and the monitoring dead angle is avoided.

Description

technical field [0001] The invention belongs to the technical field of tunnel traffic, and in particular relates to a whole-process monitoring system for driving in a tunnel and a monitoring method thereof. Background technique [0002] Transportation is an important facility for national infrastructure and plays a very important role in the development of the national economy. Ground traffic includes roadbeds, culverts, bridges, tunnels, etc. Tunnels are an important part of the traffic line. In recent years, with the rapid social and economic development of our country, there have been more and more tunnels. Therefore, it is strictly forbidden to change lanes in tunnels, let alone carry out Overtaking to prevent frequent traffic accidents in the tunnel. In the tunnel, especially at the exit of the tunnel, the light is poor, and there are usually only two or three lanes in the tunnel. Therefore, it is particularly important to monitor the tunnel in a scientific and reasona...
