Single Dual Channel Vehicle Detector For Car Park Barrier Gate And Counting System

• Small car park barrier gate automation
• Industrial parking lot access control
• Residential complex barrier gate triggering
• Basic vehicle presence sensing for car park guidance

• Car park entry/exit counting systems
• Multi-lane barrier gate management
• Real-time occupancy tracking for shopping mall car parks
• Bidirectional traffic flow analysis for airport parking lots

• Power LED (RED): Illuminates to indicate "Power ON."
• CH1 Detection LED:
  • Steady On: Indicates vehicle detection.
  • Slow Blinking: Indicates a loop short circuit or insufficient twists after the loop.
  • Fast Blinking: Indicates a loop open circuit or excessive twists after the loop.
• CH2 Detection LED:
  • Steady On: Indicates vehicle detection.
  • Slow Blinking: Indicates a loop short circuit or insufficient twists after the loop.
  • Fast Blinking: Indicates a loop open circuit or excessive twists after the loop.

• Sensitivity and frequency adjustment is facilitated through a 7-way dip switch and 10-way dip switch settings.
• Users can choose from 8 different sensitivity settings by configuring the dip switch positions according to the provided tables.
• Dip switches 6, 7, and 8 govern CH1 sensitivity, ranging from 0.8 (least sensitive) to 0.015 (most sensitive).
• Dip switches 3, 4, and 5 control CH2 sensitivity, ranging from 0.8 (least sensitive) to 0.015 (most sensitive).

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.

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.

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.
