Overview

The ClairLup-V8F 8-channel flow detection loop detector utilizes a system architecture that combines a highperformance 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-V8F 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

• A single device supports 8-channel loop connection and provides traffic flow statistics for 4 lanes. (Each lane has one front loop and one rear loop.)
• A unique combination of polling and parallel detection modes, balancing efficiency and resistance to interference.
• Response time of less than 3ms ensures real-time detection and measurement accuracy, fully supporting the use of traffic flow, electronic police, security checkpoint systems, and more.
• Quick and intelligent background frequency updates, tracking real-time changes in environmental parameters.
• Supports advanced intelligent anti-lock algorithms to ensure long-term maintenance-free operation.
• Supports real-time display of passing vehicle waveforms, allowing for a detailed understanding of all aspects of vehicles passing over the loops, greatly facilitating on-site issue analysis and identification, making installation and environmental problems clear at a glance.
• Real-time loop fault detection, automatically restoring normal operation after fault resolution.
• Supports loop open and short circuit detection, enabling the differentiation of loop fault types through fault indicator lights.
• The core detection unit utilizes pure hardware detection technology, ensuring stable and reliable operation.
• Advanced Vehicle Classification: Supports 4 vehicle types for comprehensive traffic insights. Type 1 (Unknown Vehicles) – Unclassified/unrecognized vehicles. Type 2 (Small Vehicles) – Passenger cars, SUVs, motorcycles, small trucks, tractors (length<6m). Type 3 (Medium Vehicles) – Medium-duty trucks, medium buses (length between 6m and 12m). Type 4 (Large Vehicles) – Heavy-duty trucks, large buses, trailers, extra-large trucks (length>12m). Vehicle classification accepts user self-definition.
• The device is equipped with internal memory that cyclically stores collected traffic data. With a 5-minute statistical cycle, it can retain approximately 100 days of traffic data.
• One Ethernet port is optional for easier data transmission and device management through Ethernet communications.
