Tunnel vehicle running speed detection and alarm system

Abstract

The invention provides a tunnel vehicle running speed detection and alarm system which comprises an infrared ray transmitting and receiving device, a central processing unit, a communication antenna, a power supply device and an alarm device. The infrared ray transmitting and receiving device is used for transmitting and receiving infrared rays; the central processing unit detects whether the infrared ray btransmitting and receiving device receives the infrared rays or not through the communication bus so as to judge whether a vehicle drives into the detection road section or not; the communication antenna is used for connecting the central processing unit with a cloud server so as to transmit various data in the central processing unit to the cloud server for storage; the power supply device is used for supplying power to the central processing unit; and the alarm device is used for providing prompts of different colors and sounds according to too slow or too fast speed of the vehicle running on the detection road section, so that drivers of the passing vehicles can adjust the vehicle in time.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a tunnel vehicle speed detection and alarm system. Background technique [0002] The traffic capacity of the road is generally directly related to the traffic capacity of the tunnels, bridges, and intersections on the tunnel road. Due to the influence of its own structure, it has the characteristics of poor vision and difficult evacuation, which has become a key factor affecting the traffic capacity of the highway. [0003] Due to the special structure of the tunnel, the light intensity inside and outside the tunnel is inconsistent, which will cause drivers to be disturbed by different programs due to the difference in light when passing through the tunnel, which will directly affect driving safety. In order to ensure the safety of driving through the tunnel, the traffic control department will appropriately reduce the speed of passing through the tunnel, so as to ensure...

AI Technical Summary

Problems solved by technology

With this method, on the one hand, the internal environment of the tunnel is poor, the wall of the tunnel reflects radar electromagnetic waves seriously, the installation and debugging of the equipment is very difficult, and the requirements for the installation location are very high, and it is easy to cause inaccurate measurements; on the other hand Nowadays, most vehicles are equipped with "electronic dogs". If the vehicle is driving at high speed in the tunnel, the "electronic dog" suddenly detects the speed signal, and the driver brakes and slows down in order to prevent overspeed, which is also very easy to cause rear-end collisions and other accidents. After an internal accident, the probability of a secondary accident will be much greater
