What is the main function of the Ultrasonic Node Controller?

The Ultrasonic Node Controller collects real-time parking occupancy data from multiple ultrasonic parking space sensors, performs local data aggregation, and transmits the processed information to the Central Controller for system-level management.

How many ultrasonic parking space sensors can one Node Controller support?

Each Ultrasonic Node Controller can connect to up to 25 Ultrasonic Parking Space Sensors, forming a localized detection network for a specific parking zone.

How does the Node Controller communicate with sensors and the Central Controller?

The Node Controller communicates with ultrasonic sensors via RS485, while upstream communication with the Central Controller is handled through the system bus network (RS485 / CAN-bus / Ethernet via controller architecture).

Is the Ultrasonic Node Controller suitable for large parking facilities?

Yes. Multiple Node Controllers can be deployed across different parking zones, and a single Central Controller can manage up to 61 Node Controllers, making the system scalable for medium, large, and super-large parking garages.

What happens if network communication is temporarily interrupted?

Parking space configuration data is stored locally in the Node Controller. Once communication is restored, the system automatically resumes normal operation without requiring reconfiguration.

Is the Ultrasonic Node Controller designed for long-term operation?

Yes. The controller uses industrial-grade components and includes protection against short circuits, reverse polarity, and electrical interference, ensuring stable 24/7 operation in demanding parking environments.

What warranty do you provide?

The product comes with a 1-year warranty. Defective components under normal use will be repaired or replaced during the warranty period, with lifetime technical support available thereafter.
