2 System Requirement Overview
The
intelligent reverse car-finding system is generally based on the
guidance system and serves as its complement. When customers return
to the parking lot, especially in large ones, they often struggle to
locate their vehicles. The system helps customers quickly find their
parking areas, improving satisfaction while accelerating vehicle
turnover and enhancing parking lot utilization and revenue.
Current
Urgent Issues in Parking Lots:
-
Drivers
enter the parking lot without knowing where empty spaces are,
wasting time searching at low speeds, causing congestion, increasing
fuel consumption, and polluting the air.
-
When
retrieving vehicles, complex layouts and similar structures hinder
visibility, leading to drivers entering dead ends or circling
repeatedly.
-
In
case of common incidents like parking scratches or smashed windows,
it is difficult to trace the responsible party, resulting in
financial and reputational losses for managers.
-
Managers
cannot obtain real-time parking space occupancy data, relying on
manual inspections that waste resources and lack
accuracy/timeliness, reducing parking lot efficiency.
-
During
peak hours, a large number of staff are required for manual
guidance, leading to low efficiency and high costs.
-
Managers
cannot statistically analyze parking space usage data in real time,
making it difficult to adjust operations and optimize space
allocation.
Based
on these challenges, our company has developed this parking guidance
and reverse car-finding system. By using this system, the
intelligence and informatization level of the parking lot can be
improved, replacing manual tasks with intelligent devices, saving
labor costs, and ensuring timely, accurate, and effective data.
Drivers can quickly find parking spaces and retrieve vehicles through
various guidance devices, saving time and forming a positive
impression of the parking lot.
Chapter
3 System Introduction
3.1
System Overview
In
short, 'guidance' helps drivers find empty parking spaces
quickly, while 'car-finding' locates parked vehicles
efficiently.
-
Guidance:
Data collection modules in the parking lot gather information on
parking spaces and license plates, transmit data to the central
control module via a data transmission network, which processes and
stores the information in a database server, and distributes it to
information release modules for guidance and reverse car-finding
services.
-
Car-Finding:
Data collection modules collect and bind parking space and license
plate information, transmit it to the central control module via a
data transmission network, which processes and stores the
information in a database server, and distributes it to information
release modules for car-finding services. Drivers can query vehicle
information through integrated touch query machines, and the system
plans the optimal route for car retrieval.
3.2
System Functional Design
The
system uses license plate recognition cameras installed above parking
spaces to process real-time video information, detect space status
and license plates, transmit occupancy status to guidance screens for
driver navigation, and store license plates and images in a data
server for reverse car-finding. Main functional designs include:
3.2.1
Parking Guidance (No Card Swiping Required)
Compared
with traditional card-swiping car-finding systems, this system
eliminates the need for manual card swiping, avoiding failures caused
by users forgetting to swipe cards. It provides parking guidance
through entrance information screens, indoor LED guidance screens,
and indicator lights on video parking space detectors to direct
vehicles to empty spaces.
3.2.2
Integrated Detection and Monitoring
The
system not only detects parking space occupancy in real time using
video technology but also provides high-definition recordings of all

Using
low-light CMOS video detectors with intelligent recognition
algorithms for vehicle contours and license plates, the system
achieves over 99% space status detection accuracy and over 95%
license plate recognition accuracy. It supports fuzzy queries,
allowing users to input partial license plate characters to retrieve
similar vehicle images and videos for confirmation, improving query
efficiency.
3.2.4
Reverse Car-Finding with Optimal Route Planning
The
system enables reverse car-finding via license plates, vehicle
contours, and feature recognition. Front-end detectors capture
license plate information, and users can query vehicle locations by
inputting license plates, parking time, space numbers, or searching
for unlicensed vehicles on query machines or by scanning QR codes.
The system then plans the optimal route for guidance.
3.2.5
Parking Line Violation Alarm
The
system detects vehicles parked across lines and triggers alarms via
yellow flashing lights or voice prompts to remind drivers to re-park,
maximizing space utilization and facilitating management.
3.2.6
Reserved Space Occupancy Warning
Designated
license plates can be set for reserved spaces. If an unauthorized
vehicle parks in such a space, the system triggers front-end
indicator alarms and notifies the management backend for
intervention.
3.2.7
Mobile Car-Finding with Static Route (Optional)
The
system supports uploading parking routes to a platform, allowing
users to scan QR codes and input license plates for optimal route
guidance without Bluetooth locators, offering cost-effective and
advanced functionality.
3.2.8
Bluetooth Positioning and Real-Time Navigation (Optional)
With
external Bluetooth modules, the system enables indoor positioning and
real-time navigation on mobile devices (with Bluetooth enabled),
helping users avoid getting lost in complex underground parking lots.
3.2.9
Compatibility with Mechanical Garages
Applicable
to both flat and mechanical garages, the system uses wireless
ultrasonic detectors and video detectors to monitor space status and
vehicle information in mechanical garages, enabling guidance and
reverse car-finding.
3.2.10
Seven-Color Indicator Lights for Multiple Applications
Integrated
video detectors feature seven-color indicators (red, green, yellow,
blue, magenta, cyan, white), with red indicating occupied, green
indicating vacant, and blue designating reserved spaces.
3.2.11
Fault Isolation and Self-Testing
The
system architecture includes a fault isolation mechanism: a single
device failure only affects itself, while the management center
periodically monitors device status and provides alarms for quick
troubleshooting, enhancing reliability and stability.
3.2.12
Touchscreen Experience with Modern Design
Query
terminals use capacitive touchscreens for a keyless operation
experience, offering a tech-savvy interface.
3.2.13

Chapter
4 System Composition
Video
parking guidance is used for detecting and indicating underground
flat parking spaces. Video cameras monitor space information in real
time, judging occupancy by license plates and vehicle contours, and
transmitting data to the induction manager and management platform.
The manager updates empty space counts on intersection guidance
screens to direct drivers. Space statuses are indicated by
seven-color lights (red=occupied, green=vacant, blue=reserved).
Reserved spaces (e.g., sold, long-term rental, VIP) are marked with
blue lights and license plate displays (e.g., 'VIP Space')
to prohibit unauthorized parking, with system alarms notifying
managers of violations.
Workflow:
-
Drivers
check empty space counts on the 'Entrance Information Guidance
Screen' before entering.
-
Inside
the parking lot, 'Direction Screens' at intersections
display empty space counts for each direction.
-
Each
space has a 'Parking Monitor Camera' with a green light
indicating vacancy, turning red when occupied.
-
For
car retrieval, users can search via query machines or QR codes, with
the system displaying parking locations and optimal routes; mobile
real-time navigation is also supported.

Video Parking Cameras
The
video parking space camera is an intelligent device used in parking
guidance and reverse vehicle locating systems to detect the presence
or absence of vehicles in parking spaces. Equipped with an integrated
vehicle status indicator, the camera can display six colors in real
time—red, green, yellow, blue, cyan, and purple. A red light
indicates an occupied space, green signifies an available space, and
yellow denotes an abnormal occupancy. This device is widely suitable
for environments with complex lighting conditions, such as
underground parking garages and above-ground parking structures,
effectively addressing challenges related to parking availability and
vehicle retrieval for drivers.
The
video parking space camera is available in two series: the 400
series,
which supports either three or six parking spaces. Leveraging
advanced video image processing technology, it analyzes captured
parking space images to determine occupancy status and perform
license plate recognition. This enables comprehensive
functionalities, including vehicle image capture, license plate
number recognition, and parking space occupancy detection.
