Parking lot guidance system

1、 System Introduction

1.1 System characteristics
Install a license plate recognition camera in front of the parking space in the parking lot. The license plate recognition camera processes the video information of one or more parking spaces in real time, detects the status of the parking space and the license plate number of the vehicle, and directly transmits the occupancy status of the parking space to the parking guidance screen for issuing guidance instructions to the owner. At the same time, the license plate number and parking space image are transmitted to the data server for storage and applied to reverse car search.

(1) Fully functional
The system has a comprehensive parking space guidance function, which can not only detect the empty and full status of parking spaces, but also recognize license plate numbers, and integrate the guidance and car search system into one.

(2) Cost advantage
In order to meet the two major functions of parking guidance and reverse car searching, the two systems are combined and the equipment is shared.

(3) Easy to use
The reverse car search system eliminates the driver’s positioning operation and is more in line with the driver’s usage habits. At the same time, the toll collection system can make payments through license plate numbers, advance payments, and self-service payments, greatly facilitating drivers.

(4) High reliability
The system has high reliability, using industrial grade components to improve equipment performance indicators. Due to the high failure rate of the computer, the main controller of this system can work offline, which is not dependent on the computer. The computer is only used for parameter setting and data management. The system has an alarm function in case of equipment failure, which can immediately locate and troubleshoot the problem.

(5) Strong practicality
The system structure is simple and reasonable, with high cost-effectiveness, and investment costs are saved as much as possible while meeting actual needs. The settings can be changed arbitrarily to meet the guidance needs of different periods.

(6) Easy to expand
The system has open standard interfaces and redundant interfaces, which can be added or removed at any time to meet the actual needs of customers; System reserved, can expand other functions.

(7) Electronic map
It is convenient to import floor plans of various areas of the parking lot, reflect the real-time usage of parking spaces on the electronic map, and have functions such as data statistics, charts, parking space utilization rate, and parking space turnover rate.

(8) Flexible and powerful settings
It is very convenient to set the parking area corresponding to the parking guidance screen, which can be directly reset on the management software. It can be reasonably set according to the distribution of traffic at each entrance and exit, and any parking space can correspond to any guidance screen.

 

1.2 System advantages

1. The simple architecture of this system effectively reduces the construction difficulty and architecture cost of the system. It has the characteristics of long distance and high stability, effectively ensuring the reliability and wide coverage of the system. Replacing traditional node controllers and central controllers with ordinary network switches improves system stability, reduces system failure points, and reduces customer hardware costs.

2. The license plate recognition camera adopts a dual port network communication mode. Deploying a network cable can carry 15 license plate recognition cameras, which saves a lot of network cables and labor costs compared to traditional network cameras (each network camera requires a network cable to be connected to a switch). The wiring is more beautiful and easy to find faults;

3. The front end of the camera integrates the most advanced video detection algorithms currently available, with high reliability in license plate recognition and industry-leading vehicle detection rates. It supports simultaneous recognition of multiple parking spaces (1.3 million 2 parking spaces, 2 million 3 parking spaces), and supports license plate free recognition;

4. The camera comes with RS485 function, allowing the LED vehicle display screen to be connected to the nearest license plate recognition camera, saving wiring and wiring costs.

5. The use of TCP/IP networking structure greatly facilitates equipment installation and wiring while ensuring data transmission speed and security. At the same time, all components are designed in a modular manner, and any changes to one device will not affect the normal operation of other devices. This networking structure can demonstrate significant advantages when the deployment location of products changes in the later stage. Simply connect the products deployed to the new location to the already deployed LAN to achieve normal operation, which is convenient and fast.

 

1.3 Usage process

In a parking lot using a guidance system, when the parking driver reaches the entrance of the parking lot, they can view the overall usage of parking spaces in the current parking lot based on the combination guidance screen or the total remaining space screen. If there are no available parking spaces, there is no need to enter and waste time. If there are available parking spaces, they can enter and park.After entering the parking lot, parking drivers can freely choose a parking area they want to go to based on the remaining information and arrow indications installed on the guidance screen at the intersection. Then, according to the color of the parking lights, they can intuitively and quickly find the available parking space, easily completing the entire parking process without wasting time searching for a parking space or worrying about going astray.When parking drivers want to leave the parking lot, they can use the query machine in the parking lot to search for all matching parking space videos and information through several query methods, including parking space name, license plate number, parking time, and the optimal walking route based on map mode. The owner can find their vehicle in the shortest possible time, drive away from the parking lot, and improve the turnover rate of the parking lot.

1.4 System composition

The system mainly consists of license plate recognition cameras, query machines, guidance screens, switches, servers, software, etc.
