Dual-way Loop Detector With Inductive Vehicle Loop Detector On Sale

Dual-way Loop Detector

In the intelligent parking lot industry, vehicle detectors are a common component. These detectors can be categorized based on their underlying technology into several types: toroidal coil vehicle detectors, ultrasonic sensor vehicle detectors, radar detection vehicle detectors, and video detection vehicle detectors. Among these, toroidal coil vehicle detectors are the most widely used.

Toroidal Coil Vehicle Detectors

Toroidal coil vehicle detectors work by embedding a ground-sensing coil under the lane. When a vehicle passes over the coil, it alters the magnetic field, which the detector then uses to calculate parameters such as vehicle flow, speed, and vehicle length. This technology is mature, easy to install, and cost-effective, making it a popular choice in the parking lot industry.

Role in Intelligent Parking Systems

In intelligent parking systems, ground-sensing vehicle detectors primarily serve as triggers to detect the presence of a vehicle on the lane. Their reliability and affordability have led to their widespread adoption.

Key Advantages

• Mature Technology: Proven and reliable performance.
• Ease of Installation: Simple to set up under the lane.
• Cost-Effective: Lower costs compared to other detection technologies.

Dual-way Loop Detector

As a traditional traffic information dual-way loop detector device, the toroidal coil vehicle detector offers exceptional reliability and cost-effectiveness, making it a highly viable option for future applications. The core technology involves a coil buried in the ground, which is connected to a tuning loop supported by a constant current source through a transformer. This setup generates an electromagnetic field in the space around the coil.

How It Works

1. Electromagnetic Field Generation: The coil buried in the ground generates an electromagnetic field.
2. Vehicle Detection: When a vehicle enters the coil's magnetic field, eddy currents are induced in the vehicle's metallic parts.
3. Inductance Change: These eddy currents generate a new magnetic field that opposes the original one, reducing the coil's total inductance.
4. Frequency Deviation: The change in inductance shifts the tuning frequency from its original value, creating a higher frequency signal.
5. Signal Processing: This frequency deviation is detected by comparing it with the voltage from a voltage-controlled oscillator.
6. Vehicle Presence Signal: The phase comparator's output signal controls the voltage-controlled oscillator to track the resonant frequency changes, resulting in a pulsed output signal. An output amplifier then amplifies this pulsed signal.
