The vehicle entrance and exit management system automatically captures, recognizes, and records license plates, vehicle models, colors, etc. based on the parking position of the vehicles, and transmits and processes integrated intelligent barrier devices to control the entry and exit of vehicles, making the system more effective in identifying and managing vehicles entering and exiting the site.

1.1 Advantages of License Plate Recognition

License plate recognition is undoubtedly the most intelligent and convenient parking lot management technology.

1) For fixed vehicle management, "license plate recognition" has the following advantages:

*Thoroughly solve the problem of one card with multiple vehicles in "card management";

*Thoroughly solve the problem of cards not being carried during card management;

*Thoroughly solve the problem of card replacement and replacement caused by card loss in "card management";

*Thoroughly solve the communication work regarding the installation and placement of cards in "card management";

*Other card related issues~~

2) For temporary vehicle management, "license plate recognition" has the following advantages:

*Thoroughly solve the problem of overcharging personnel during card management;

*Completely freeing toll collectors from manual card issuance work, they only need to be responsible for receiving money - even if equipped with entrance card issuing machines, there is often a need for someone to help pass the "temporary card" between the "entrance card issuing machine" and the "temporary vehicle", which often deviates from the initial goal of saving human resources. Because the parking distance of temporary vehicles is often far from the issuing machine, this is a subconscious and normal reflection of people's fear of hitting the issuing machine and the barrier;

*When completely solving the problem of "card management", some temporary vehicles mixed out of the parking lot, causing the management to lose temporary cards and parking fees;

*Thoroughly solve the problem of individual fixed vehicles maliciously taking temporary cards when entering the venue, resulting in the continuous loss of temporary cards;

*Other card related issues??

2.1 System Architecture and Components

The parking lot toll system has the function of managing temporary vehicle charges and authenticating long-term users.

*Integrated display and control machine for entry and exit, broadcasting voice and displaying vehicle entry and exit information, parking time and payment information, etc.

*The barrier gate is used to physically block vehicles and control their entry and exit.

*Ground sensing is used to detect vehicles and achieve the "one vehicle, one card" function.

*Anti smashing ground sensing is used to detect vehicles and achieve barrier anti smashing function.

*Management center, used for managing and storing image records, etc.

The RS485 communication method is used between the import and export display control integrated machine and the computer, which greatly facilitates the installation and wiring of the equipment while ensuring data transmission speed and security. At the same time, all components are designed in a modular manner, and changes to one device will not affect the normal operation of other devices.

The main body of the parking lot fee management system adopts a TCP/IP network structure, from the booth computer to the management center computer, and from the high-definition recognition all-in-one machine to the booth computer. Convenient and fast.

3、 Main equipment

The configuration of the parking lot management system includes a parking lot control machine, automatic lifting barriers (advertising barriers are mainly used in shopping malls and residential areas, folding barriers are suitable for use in restricted areas such as underground warehouses, and straight pole barriers and fence barriers can be customized according to on-site and user conditions), long-distance card readers, induction cards, vehicle sensors, ground sensing coils, communication adapters, cameras, transmission equipment. If functions such as contactless payment and electronic invoices need to be achieved, ETC system equipment, self-service parking channel machines, and parking lot system management software need to be added.

As a typical computer network application system, the scheme design of the vehicle access management system should follow the principles of practicality, safety, advancement, economy, reliability and expandability. On the basis of ensuring the effective, stable and reliable performance of the system, while considering the progressiveness of the system, on the premise of meeting the requirements of the security level, try to reduce the system cost, fully consider the actual needs of users and the development trend of information technology, and configure the scheme in line with the user's site environment, scene selection functions, etc.
