Dual Channel Loop Detector For Lane Control And Vehicle Classification

The JUTAI Dual Channel Loop Detector (Models LD200/LD202) is a professional-grade solution engineered for precise lane control and vehicle classification, integrating dual independent channels, configurable direction modes, and adjustable sensitivity to meet the demands of traffic management, toll plazas, and smart road systems. It supports both coordinated lane control (e.g., one-way passage, bidirectional separation) and accurate vehicle classification (distinguishing small cars, SUVs, trucks, and trailers), making it ideal for municipal traffic, commercial toll stations, and industrial lane management.

Core Features (Lane Control & Vehicle Classification Optimized)

  1. Dual-Channel Lane Management: Functions as a unified system for bidirectional lane control or two independent detectors for separate lane monitoring, supporting one-way passage enforcement, lane closure alerts, and traffic flow diversion.
  2. Vehicle Classification Capability: 8-level adjustable sensitivity (0.015%–0.8% DL/L) per channel + trailer-specific sensitivity boost (via DIP switch 1) enables classification of vehicles by size/weight—from motorcycles and compact cars to heavy-duty trucks and trailers.
  3. 3 Direction Detection Modes: Precisely identifies vehicle travel direction (CH1→CH2 or CH2→CH1) for lane-specific triggering (e.g., toll collection, barrier activation) and bidirectional traffic statistics.
  4. Anti-Interference Lane Stability: 4-step selectable frequency (20–100 kHz) eliminates cross-talk between adjacent lanes or metal infrastructure, ensuring reliable detection even in high-density traffic scenarios.
  5. Lane Safety Protection: Presence mode continuously monitors vehicle occupancy in lanes; triggers alerts or pauses lane equipment (e.g., toll gates, barriers) to prevent collisions during high-speed operations.
  6. Dual Power Adaptability: LD200 (100–240V AC) for permanent lane installations; LD202 (12–24V DC) for temporary lane control (e.g., construction zones, event traffic diversion).
  7. Intuitive Fault & Status Alerts: LED indicators for power, lane detection, and loop faults (short/open circuit, incorrect loop turns) enable quick on-site troubleshooting to minimize lane downtime.
  8. Flexible Output Modes: Supports pulse output (for lane trigger actions) and presence hold (for continuous vehicle monitoring), with 10-minute auto-reset (via DIP switch 2) to resolve misoperations.

Key Applications

  1. Toll Plaza Lane Control: Classifies vehicles (cars/trucks) for tiered toll collection, controls lane barriers via direction detection, and monitors bidirectional traffic flow.
  2. Municipal Traffic Lanes: Manages bus lanes, HOV lanes, or restricted-access lanes (e.g., emergency vehicle lanes) with vehicle classification and one-way enforcement.
  3. Industrial Lane Management: Separates forklift/truck lanes from pedestrian channels in factories/warehouses, triggering high-speed doors or safety alerts.
  4. Highway On/Off Ramps: Controls lane access, classifies vehicles for traffic flow analysis, and supports congestion management systems.
  5. Construction Zone Lanes: Temporary lane control (with LD202 DC model) for traffic diversion, vehicle classification, and safety monitoring.
  6. Parking Lot Entry/Exit Lanes: Separates entry/exit lanes, classifies vehicles for size-specific parking (e.g., large vehicle bays), and controls barrier gates.
  7. Border/Checkpoint Lanes: Classifies commercial vehicles vs. passenger cars, manages lane flow, and integrates with security access systems.
  8. Logistics Yard Lanes: Controls loading/unloading lane access, classifies delivery trucks/trailers, and optimizes yard traffic scheduling.

Application


The JUTAI LD200/202 double-channel vehicle loop detector series, equipped with direction recognition function, is ideal for numerous single-channel entry and exit scenarios. When integrated with the JUTAI One door controller (Model: AC-11), JUTAI gate barrier (Model: BR-110), and JUTAI long-range RFID reader (Model: PUHF-9), along with high-temperature resistance loop coils (Model: JTHT-11), it forms a seamless solution for single-channel entry/exit access control systems.


Dual Channel Loop Detector For Lane Control And Vehicle Classification 12

The working principle is as follows:

  1. Entry Process:

    • When a car enters the community or parking lot, the two loop coils are pressed simultaneously.
    • The JUTAI Double Channel Loop Detector (LD-200/202) triggers the UHF reader located at the entrance.
    • The UHF reader reads the card ID and sends it to the controller (AC-11) via Wiegand output.
    • The controller verifies the ID's validity and outputs a relay signal to open the gate barrier.
    • The car enters the community or parking lot, and as it passes the barrier gate, the barrier arm lowers automatically.
    • The JUTAI Single Channel Loop Detector (LD-100/102) ensures safety and anti-smashing functionality during this process.

  2. Exit Process:

    • When a car exits the community or parking lot, it passes by an inside UHF reader.
    • The LD-200/LD-202 triggers the UHF reader, which reads the card and sends the ID to the controller.
    • The controller verifies the ID's validity and outputs a relay signal to open the gate barrier for the car to exit.
    • As the car passes through the barrier gate, the barrier arm lowers automatically.
    • The LD-100/102 provides safety and anti-smashing functionality during this process.

  3. Direction Recognition:

    • The Direction Recognition Function of LD-200/LD-202 ensures that the double channels loop detector does not trigger the signal again when the car passes another UHF reader, thereby recording only the entry or exit records in the system.

The JUTAI LD-200/202 Double Channel Loop Detector can also function as two independent single-channel loop detectors. This configuration is suitable for standard one-in and one-out parking lots, where there is one barrier and one long-range reader at both the entrance and exit.

In this setup, one loop coil is used to trigger the reader and read the card, while the other loop coil is dedicated to the barrier's anti-smashing function. By utilizing the LD-200/202 as two independent loop detectors, there is a potential cost-saving benefit from an economic standpoint. This setup reduces some of the hardware costs associated with using separate detectors for each function.

This functionality is achieved by enabling the Independent Working Mode feature of the LD-200/202, allowing it to operate effectively in this dual capacity.
