What is Integrated Detector in Parking Guidance System?

An integrated detector is the core front‑end all‑in‑one hardware unit for ultrasonic‑based Parking Guidance System (PGS). It merges ultrasonic vehicle‑detection probe and multi‑color RGB LED bay‑status indicator into one compact housing, replacing traditional split‑type separate sensor and indicator setup. It continuously detects whether a parking bay is vacant or occupied, shows visual bay‑status locally, and transmits real‑time parking‑bay data via RS485 bus to zone node controller and central controller for further processing by PGS‑SW parking guidance management software.

Core Internal Components of Sintronic Integrated Detector

The integrated detector integrates ultrasonic ranging module, RGB‑LED indicator, bus‑communication circuit inside ceiling‑mount compact housing:

1. Ultrasonic transmit‑receive probe: High‑frequency ultrasonic transducer, measures distance by time‑of‑flight echo to judge vehicle presence above parking bay.
2. Multi‑color RGB LED indicator: Built‑in high‑brightness status lamp; Green = vacant bay, Red = occupied bay, Blue = reserved / handicapped‑priority bay.
3. Local micro‑processing MCU chip: Handles echo‑signal filtering, anti‑misjudgment algorithm, LED‑color switching and RS485 data‑packaging.
4. RS485 bus communication terminal: Daisy‑chain bus‑wiring interface for connecting multiple detectors to zone node controller.
5. Surge & reverse‑polarity protection circuit: Protect hardware from unstable bus‑power input for long‑term 24/7 car‑park operation.

Main Types of Integrated Detector

1. Standard indoor integrated detector: For underground enclosed car‑park, 1.8‑2.8 m ceiling‑mount installation height, most widely‑used model for mall & office parking lots.

2. Outdoor‑grade waterproof integrated detector: IP54 weather‑proof housing, for semi‑open outdoor parking zones, dust‑proof & moisture‑resistant.

3. High‑disturbance enhanced‑algorithm integrated detector: Optimized anti‑interference firmware for complicated‑structure parking‑lots with beams, pipelines and low ceiling height.

All Sintronic integrated detectors adopt standard RS485 bus protocol, fully compatible with Sintronic zone node controller, central controller and PGS‑SW parking guidance management software.
