The invention relates to the technical field of road early warning, and discloses an intelligent
traffic risk early warning device and method.The intelligent
traffic risk early warning device comprises a
vehicle type recognition module, a vehicle meeting conflict judgment module and a conflict isolation protection module, the
vehicle type recognition module recognizes and collects vehicle images through a YOLOv7 method based on fusion CBAM enhancement, outputs various kinds of information of vehicles passing through a curve, and sends the information to the collision isolation protection module; the collision isolation and protection module is used for receiving a collision
signal and outputting the collision
signal to the meeting collision judgment module, establishing a summarized
data set of meeting actual conditions and executing a meeting
safety control method, and the collision isolation and protection module is used for controlling the lifting of a plurality of flexible warning columns arranged at the entrances of the curves on the two sides based on the meeting collision judgment module. According to the device, the minimum vehicle
turning radius is dynamically calculated in combination with the vehicle meeting conflict judgment module and compared with the same type of a vehicle meeting critical model, and
signal early warning dynamic isolation dual protection is matched, so that the problems that a traditional convex mirror depends on subjective judgment of a driver, and an existing early warning device is manually operated and poor in environmental adaptability are solved; and the safety of vehicle meeting at the mountain road curve is improved.
