Overview

TThe ClairLup-V4F 4-channel flow detection loop detector utilizes a system architecture that combines a high performance processor with an FPGA (Field-Programmable Gate Array). The core detection algorithm is implemented using pure hardware technology. The flexibility of ARM, combined with the powerful processing capabilities of FPGA, results in a system known for its quick response, high accuracy, strong resistance to interference, and flexible scalability.

The ClairLup-V4F supports comprehensive traffic flow data detection, including flow, occupancy, speed, inter-vehicle spacing, headway time, and the percentage of following vehicles. This system is widely applicable in traffic-related systems, such as traffic flow monitoring, traffic enforcement, and security checkpoints, on urban roads, highways, bridges, tunnels, and various other road segments.
 

Key Features

• 4-channel loop support for 2-lane traffic flow statistics (front + rear loops per lane).
• Features an innovative polling + parallel detection mode, balancing efficiency and interference resistance.
• A fast response time of less than 3ms ensures real-time detection and measurement accuracy.
• Rapidly and intelligently updates the background frequency, continuously tracking changes in environmental parameters.
• Supports advanced intelligent anti-lock algorithms, ensuring long-term maintenance-free operation.
• Provides real-time display of passing vehicle waveforms, allowing for a detailed understanding of all vehicle passage details through the loops. This greatly facilitates on-site issue analysis and troubleshooting, making installation and environmental problems instantly apparent.
• Offers real-time loop fault detection and automatically restores normal operation after the fault is resolved.
• Supports loop open and short circuit detection, enabling the differentiation of loop fault types through fault indicator lights.
• Flexible I/O output capabilities, with I/O output functions customizable according to user requirements.
• The core detection unit utilizes pure hardware detection technology, ensuring stable and reliable operation.
