The intelligent vehicle type recognition toll collection system for Highways is a modern toll collection solution integrating infrared beam scanning technology and intelligent toll calculation algorithms. The system uses infrared beam scanning sensor arrays deployed on both sides of the toll lane to accurately capture vehicle contour height information, enabling automatic vehicle type classification and differentiated toll collection, effectively improving traffic efficiency and toll collection accuracy.
Core Functions
Infrared Height Detection: The system deploys multiple sets of infrared transmitters and receivers on both sides of the lane, forming a three-dimensional detection light curtain. When a vehicle passes, the height and number of beams blocked are recorded in real time, constructing the vehicle's three-dimensional contour data. Height recognition accuracy can reach ±2 cm.
Intelligent Vehicle Type Determination: Based on height data, the system automatically distinguishes between passenger vehicles, freight vehicles, and cars, ensuring that tolls are collected according to vehicle type.
Technical Advantages
Infrared beam scanning technology has all-weather operation capability, unaffected by environmental interference such as sunlight, rain, and fog, with a detection response time of less than 100 milliseconds.
