Method for manufacturing road guidance system in fog area

Due to the limitations of natural conditions and geographical conditions, many highways have dense fog on certain sections. Traffic accidents caused by fog have caused significant losses to people's lives, property and social and economic losses. At present, the domestic precautionary measures taken in areas where fog is likely to occur are mainly to install inducing signs and broadcasts on both sides of the road, and the vehicles entering the fog zone are slowly moving forward, but the distance of the vehicles ahead cannot be indicated. The driver can only estimate the distance by observing the fog lamp at the rear of the vehicle. The dense fog is easy to cause misjudgment and cause the vehicle rear-end collision.

Aiming at the problem of difficulty in measuring the distance between the front and rear vehicles in the foggy road in the prior art, the object of the present invention is to provide a fog road guidance system, which can provide road condition information and road profile information for the traveling vehicles on the fog road. The location range assists the driver in judging the traffic conditions in the fog area and reduces the probability of traffic accidents such as rear-end collisions.

Based on the above objectives, the technical solution provided by the present invention is as follows:

According to an aspect of the invention, a fog road guidance system is provided, comprising:

The control center of the fog area, the control center of the fog area is set in the fog area, the control center of the fog area is connected to all the road guidance nodes, and the control center of the fog area can monitor the visibility in the fog area and the traffic conditions of the fog area control the road guidance nodes. Working status and sending broadcast information to the driving vehicles on the fog road;

A plurality of highway inducing nodes, each of which is disposed on both sides of the foggy road, and each of the highway inducing nodes can detect the traveling speed of the traveling vehicle on the foggy road under the control of the foggy area control center, and use the optical signal Informing the distance range between the driving vehicle and its preceding vehicle, multiple highway guidance nodes are evenly arranged along the highway, and the relative information between the plurality of highway guidance nodes is independent.

Among them, the fog area control center includes:

The visibility sensor is disposed in the fog zone, and the visibility sensor can detect the visibility in the fog zone. When the visibility sensor detects that the visibility in the fog zone is lower than a preset standard visibility threshold, the visibility sensor sends an alarm to the fog zone control center. signal;

The information disclosure board and the information disclosure board are installed in the control center of the fog area. The information disclosure board is used for the staff of the fog area to provide real-time information for the fog area of ​​the fog area to analyze and formulate countermeasures.

Inducing the light source, the induced light source is disposed on the anti-collision guardrail on both sides of the foggy road, and the induced light source is continuously illuminated after being activated by the node controller, and is used for providing the outline and guiding service to the traveling vehicle on the foggy road;

Moreover, the vehicle detector continuously detects the traveling speed of the traveling vehicle passing the vehicle detector on the foggy road, and the vehicle detector continuously detects the traveling vehicle passing the vehicle detector on the fog road, and blocks the infrared receiver to receive the infrared light source signal. For the duration of the vehicle, the vehicle detector calculates the travel speed of the traveling vehicle passing the vehicle detector according to the length of the vehicle body of the traveling vehicle and the duration of blocking the infrared receiver receiving the infrared light source signal.
