Overview

Ultrasonic parking guidance system provides visual indication to driver while searching for a vacant parking spaces: ultrasonic sensor at each space monitors real-time occupancy and reports by changing color of individual lighted space indicator. A green light signifies that the space is vacant while a red light indicates that the space is filled or already occupied. At the meantime, availability information will be accordingly updated on decision point signs. No more work for the driver as to which parking level has available spaces for parking.

How does it Works?

1st Layer: Data Acquisition
Ultrasonic sensor at each space forms system foundation. It detects parking status and reports to system controller on R485 Bus.
2nd Layer: Data Process & Transmission
System controller processes data acquired form ultrasonic sensor, update real-time information to associated signage, reports to upper layer on CAN Bus.
3rd Layer: Data Analysis
Host management software analyzes data and generates statistic reports. Browser-based architecture allows remote access to system.

System Structure

Benefits (Ultrasonic)

• An ultrasonic parking guidance system reduces “time to find a space” by 44%, shown on an independent study
• Noticeably reduces congestion in the car park, allowing for faster exiting speed (by around 10%)
• Creates 100% usage of the car park by making every space “visible” to the drivers with decision point signage
• Less labor is required to manage the parking
