Embodiment 1

[0033] like figure 1 As shown, the whole-process monitoring system for driving 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 buried on the driveway, 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 the card issuing casing 11 is provided with a camera 111 facing the side of the vehicle driving direction. The upper surface of the card issuing casing 11 is One end near the camera 111 is provided with a distance sensor 112, 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 host computer 12 is used ...

Abstract

The invention provides a whole-course monitoring method for driving in a tunnel. The whole-course monitoring method comprises the steps that a vehicle selects one lane of a tunnel to enter the tunnel;the vehicle enters the tunnel and passes above a card issuing device; a card pulling mechanism in a card issuing host transmits an electronic card to a card holder in advance; a camera records the license plate number of the passing vehicle, and a distance sensor detects the height of the vehicle chassis; a first lifting mechanism in the card issuing host rapidly pushes the card holder and the electronic card to reach corresponding heights; an electromagnet in the electronic card is started to work, and then the electronic card is attracted to the vehicle chassis; the electronic card collectsthe moving speed and the moving track of the vehicle along with the whole process in which the vehicle walks in the tunnel; the vehicle passes over a card receiving device, and a reader in the electronic card reads an electronic tag arranged on the card receiving device, so that the electromagnet is triggered to stop working; and the electronic card is separated from the vehicle and falls into acard receiving host; Compared with a traditional fixed-point snapshot mode, whole-process monitoring is achieved, and monitoring dead angles are avoided.

Description

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