Description

Technical Field

[0001] The present invention relates to the technical field of traffic management, and in particular to an underground road emergency collision adaptive handling system and method. Background Art

[0002] Tradable right-of-way roads refer to urban road systems used in the right-of-way trading model. Due to their fast and dedicated characteristics, they are mostly in the form of underground roads or tunnels to control the number of entry and exit nodes and improve traffic efficiency and attractiveness. However, unlike highways, underground road systems are in a relatively closed environment. When a vehicle stalls or brakes fail, serious traffic collisions are prone to occur. Therefore, it is necessary to design emergency deceleration or collision devices for stalled vehicles to minimize the impact of traffic accidents, ensure the safety of vehicle personnel, and improve the resilience and safety of underground roads.

[0003] Emergency anti-collision devices are mainly simple anti-collision piers or speed reduction slopes. Easy-to-avoid collisions are mostly set at road bifurcations, and speed reduction slopes are mostly used in spacious areas of highways. They cannot be used in narrow and limited spaces such as underground roads. At the same time, when a car catches fire, there are significant differences in fire handling between fuel vehicles and new energy vehicles. For example, due to chemical reactions such as fire and explosion of battery compounds in new energy vehicles, water fire extinguishing cannot be well applied to new energy vehicles. Therefore, different disposal measures are needed for different types of vehicles, which all rely on the rapid identification and detection of vehicle types. The existing relevant technical solutions cannot meet the above needs. It is urgent to use current advanced information sensing facilities and artificial intelligence technologies to realize vehicle type identification, classification disposal, automatic alarm, remote control and other functions.

The method for adaptively handling underground road emergency collisions according to claim 9, characterized in that: The central processing unit has a built-in vehicle collision detection method, and the specific steps are: S1: Search for pictures with the themes of "car license plate" and "car collision" from Baidu search, download the first 2000 pictures respectively and store them in the data storage device in "JPEG" format, and establish a first data set U1 corresponding to car license plate pictures and a second data set U2 corresponding to car collision pictures; S2: Use labelimg software to manually mark the types of the block diagrams in the first data set U1 and the second data set U2; in the first data set U1, the ones marked as "1" are fuel vehicles, the ones marked as "2" are new energy green-plate vehicles, and the ones marked as "3" are no vehicles; in the second data set U2, the ones marked as "4" are fires, and the ones marked as "5" are no fires; S3: Use Yolov8 software to train the calibrated first data set U1 and second data set U2, respectively, and establish a "car type" detection model and an "accident type" detection model respectively; S4: Call the image information in the data storage device in real time, generate a "JPEG" format picture every 0.5s, and input the picture into the "car type" detection model and the "accident type" detection model as the detection object; S5: If the frame type of more than 3 pictures among the 5 pictures input continuously is "1" or "2", an alarm signal will be sent to the alarm prompt device; When the block diagram type is a combination of "1" "4" or "1" "5" or "2" "5", a first signal will be sent to the fire extinguishing device; when the block diagram type is a combination of "2" "4", a second signal will be sent to the fire extinguishing device; S6: If the frame type of more than 3 pictures among the 5 pictures input continuously is "3", return to S4.
