Embodiment 1

[0033] Such as figure 1 As shown, a method for monitoring the driving state of vehicles in a tunnel starts from the initial state and includes the following steps:

[0034] (1) Judging whether there is a vehicle entering the tunnel, monitoring and tracking the driving status of the vehicle entering the tunnel, and converting the vehicle's driving speed, distance from the tunnel entrance, or status information of whether it has stopped due to failure into electrical signals;

[0035] (2) Enter and process the signal and output the selection signal: signal processing includes signal control, detection, amplification, and select the signal that affects driving safety to enter and output;

[0036] (3) Output the selected warning signal, including the driving speed signal, the distance signal from the tunnel entrance or the vehicle failure signal.

[0037] In the above steps, a vehicle failure misjudgment processing step is also included. By judging the driving speed of the vehicl...

Embodiment 2

[0040] Such as figure 2 Shown is a monitoring device for the driving status of vehicles in a tunnel, including:

[0041] A monitoring unit 1 for monitoring the driving state of vehicles in the tunnel, the monitoring unit 1 monitors the driving state of vehicles entering the tunnel, and converts the monitored driving state of vehicles into electrical signals;

[0042] The signal processing unit 2 that receives and processes the vehicle driving state signal from the monitoring unit, the signal processed by the signal processing unit 2 includes the vehicle driving speed signal, the distance signal between the vehicle and the tunnel entrance and the vehicle fault signal, and outputs the processed signal to the warning display unit 3;

[0043] The warning display unit 3, which is installed at a conspicuous position at the tunnel entrance, displays and outputs the received vehicle speed signal processed by the signal processing unit 2, the distance signal between the vehicle and t...

Embodiment 3

[0048] Such as Figure 4 Shown is the second embodiment of the vehicle driving state monitoring device in the tunnel. The monitoring unit 1 of this embodiment adopts the radar monitoring unit 13, which is used to monitor the driving state of the vehicle after the vehicle enters the tunnel, including the driving speed and the tunnel entrance. The distance or whether there is a fault, and these states are converted into electrical signals and sent to the signal processing unit 2.

[0049] The signal processing unit 2 includes a control circuit 21 , a detection circuit 22 , a signal processing circuit 23 and a power supply 24 . The signal processing unit 2 is to process the signal transmitted by the monitoring unit, and select and output the driving speed signal, the distance signal between the vehicle and the tunnel entrance, or the vehicle failure signal that affects driving safety.

[0050]The warning display unit 3 includes yellow distance warning scale lights arranged in a ...

Abstract

The invention discloses a method for monitoring running states of vehicles in a tunnel. The method comprises the following steps: (1) monitoring vehicles entering in a tunnel, tracking running states of the vehicles, and converting monitoring signals into electrical signals; (2) receiving and processing the monitoring signals; and (3) displaying the processed running state signals of the vehicles in the tunnel at a conspicuous position of an entrance of the tunnel in order to warn drivers coming into the tunnel of selecting running lanes and adjusting running speeds. According to the method provided by the invention, the running states of the vehicles in the tunnel are monitored, the running states of the vehicles are converted into the electrical signals and the electrical signals are processed, and vehicle speed signals and signals of distance between vehicles and the entrance of the tunnel which influence the running safety are displayed at a conspicuous warning display screen of the entrance of the tunnel in order to warn the drivers coming into the tunnel of notifying the running states of the vehicles in the tunnel, thereby guaranteeing the running safety of the vehicles. The invention also provides a monitoring device of the method for monitoring running states of vehicles in the tunnel.

Description

technical field [0001] The invention relates to a method for monitoring the running state of vehicles in a tunnel, and at the same time relates to a monitoring device for the running state of vehicles in the tunnel. Background technique [0002] With the development of society, expressways have extended in all directions, bringing many conveniences to people's lives. However, due to the limitation of the geographical environment, in order to reduce the damage to the environment, the construction of the expressway will inevitably need to build tunnels when passing through the mountains. In some remote mountainous areas, there is no lighting in the tunnel of the expressway. When the vehicle enters the tunnel, the driver is affected by the environment and temporarily loses his eyesight. A rear-end traffic accident occurred. [0003] Therefore, in order to reduce the occurrence of traffic accidents in the tunnel and find a monitoring method for the driving status of the vehicl...
