Technical Proposal for an Intelligent Parking System

Chapter One   Project Overview

One   Background

As the national economy continues to grow, automobiles are increasingly becoming a common household item. Coupled with China’s vigorous efforts in recent years to develop its automotive industry and the frequent introduction of policies designed to encourage household car ownership, the number of vehicles on the road has risen year after year. According to data from the China Association of Automobile Manufacturers, in 2014 China’s automobile production and sales reached 24 million units, positioning the country to maintain its position as the world’s largest automobile producer and seller for the sixth consecutive year.

As the number of vehicles on the road continues to grow rapidly and parking facilities expand in scale, the conflict between cars and parking spaces in urban areas has become increasingly acute. Issues such as difficulty finding a parking spot, locating one’s own vehicle, and managing parking lots are cropping up with alarming frequency.

Two   Project Overview

The demand for intelligent parking management aims to achieve smart operation of parking facilities, with regular monthly‑pass holders as the primary service clientele and temporary visitors accommodated as well. The goal is to ensure convenient, swift, and secure access for all users, while enabling the management team to operate in a scientifically sound, highly efficient manner and deliver high‑quality, courteous service. This will play a crucial role in elevating the management level and overall service standards of the facility. Following thorough research and in response to future development needs, our company has meticulously designed a cutting‑edge intelligent parking management system, encompassing both contactless IC‑card‑based access control and license‑plate‑recognition‑based access control solutions.

In a parking management system based on contactless IC cards, vehicle owners holding monthly‑pass or VIP cards, upon detection by the vehicle detector, simply swipe their IC card across the reader at the entry/exit control unit. The reader verifies the card’s validity; if valid, the barrier arm automatically rises to grant access and records the relevant data in the database. Invalid IC cards or vehicles entering or exiting without a valid card are denied passage. For temporary parkers, once the vehicle detector confirms the presence of a vehicle, the driver presses a button on the entry control unit to obtain an IC card, which is then read to authorize entry. Upon departure, the driver hands the temporary card to security for verification and pays the parking fee; if no irregularities are detected, the barrier rises to allow exit.

In a license‑plate‑recognition‑based parking management system, for areas open to internal vehicles, when authorized or VIP vehicles enter or exit the parking lot, the entrance/exit cameras automatically capture their license plates. For vehicles with valid plates, the barrier arm rises to grant access and the corresponding data is stored in the database. Vehicles with invalid plates are denied entry. For areas open to all vehicles, upon entering the parking lot, the entrance camera automatically captures the vehicle’s license plate and saves an image; the barrier then opens to allow passage. Upon exiting, the exit camera similarly captures the license plate and saves an image, which is compared with the image captured at entry. If the comparison is successful, the driver pays the fee, and the barrier opens to permit passage.

Meanwhile, in large underground parking facilities, drivers often struggle to find a spot and, upon returning, can easily become disoriented, unable to locate their vehicle. Dahua’s intelligent parking guidance solution employs comprehensive video‑based navigation, integrated with on‑site guidance displays and reverse‑car‑finding terminals, to help drivers quickly secure a parking space and pinpoint their vehicle’s location. This significantly reduces management costs, eliminates the frustration of searching for a spot, and enhances customer satisfaction with both the parking facility and its managing property company. It also accelerates vehicle turnover, boosts parking utilization and economic returns, and elevates the overall level of parking‑lot management, thereby strengthening the external image of the property management firm.

Chapter Two   Solution

One   Solution Analysis

1  Problem Solving and Benefits

• It addresses the limitations of traditional parking facilities, which fail to display real-time vacancy information and prevent drivers from selecting an entry method at the entrance. The proposed solution features parking‑space‑availability displays that provide up-to-the-minute updates on available spots across all levels, alleviating customers’ concerns about finding a space upon arrival and enabling them to choose the most convenient floor based on current availability.

• This solution addresses the low efficiency of traditional parking lots, where drivers must stop to retrieve a card upon entry and swipe it to exit. In this system, entrance and exit cameras automatically recognize vehicle license plate information, recording the license plate number, timestamp, and whether the vehicle belongs to an internal user or an authorized monthly‑pass holder. This enables seamless, card‑free access, significantly improving the efficiency of vehicle entry and exit.

1.   The system shall provide comprehensive reporting and statistical capabilities, including metrics such as berth utilization rate, current occupancy rate, and berth turnover rate, to furnish a scientific, data‑driven basis for decision‑making related to parking‑lot berth allocation and other operational considerations.

2.   Precise timing and billing management: Entrance and exit cameras automatically detect vehicle arrivals and departures, enabling accurate timekeeping and billing for parking. Intelligent solutions enhance the efficiency and transparency of parking fee management, resolve disputes over parking charges, and reduce public concerns and complaints.

3.   Information Platform‑Based Management: The entire system is managed entirely through a visualized operations platform. By building this platform, the system gains enhanced capabilities for integrating, processing, and disseminating information, significantly improving management efficiency.

2  Effective Parking Management

Parking‑space detection employs a high‑definition camera that integrates both sensing and display functions, enabling a single camera to monitor two, three, or six spaces simultaneously. When all spaces are occupied, the indicator light turns red; as soon as one space becomes available, the light switches to green. Mounted directly above each parking spot, the camera provides a clear, real‑time overview of parking‑space occupancy, allowing users to quickly locate open spots, speeding up the parking process and facilitating efficient management by facility operators.

3  System stabilization

The system’s backend management platform is implemented on an embedded Linux all-in-one appliance, ensuring 30/24-hour stable operation, enhancing reliability, and reducing maintenance costs. Additionally, the system seamlessly integrates with third-party business systems and leverages J2EE‑based enterprise middleware technology, facilitating value‑added application development by third-party vendors.
