With the social and economic prosperity and the continuous improvement of people’s living standards, transportation has gradually become an indispensable necessity in daily life. In recent years, the rapid growth of various types of vehicles, especially private cars, has become an important sign of economic improvement. At the same time, the construction of transportation infrastructure and vehicle safety management are increasingly important topics that every urban construction planner is facing. The design of this scheme is based on the mature development and successful application of RFID (Radio Frequency Identification), an industry that is currently popular in the world and is increasingly valued in China. Its non-imitability, anti-interference, anti-impact, rapid identification, and intelligent discrimination will undoubtedly provide a brand-new solution for all kinds of parking lot management. In response to the needs of high-end communities, enterprises, and institutions for intelligent parking lots, Shenzhen Aostar Electronics Co., Ltd. has launched an intelligent parking lot management system that integrates computer technology, short-range microwave communication technology, image digital processing technology, and automatic control technology. Realize the automatic identification and information management of vehicles, improve the efficiency and safety of vehicles, and count vehicle access data to facilitate management personnel to dispatch, so as to reduce the labor intensity of management personnel and effectively prevent toll loopholes.
1. Project features
The biggest feature of the project is that it combines mature smart card technology, wireless communication technology, and advanced software technology, organically integrates various mature technologies, and applies them to actual engineering needs.
At the management station, the non-contact smart ID card is used for automatic identification and management of entering and exiting vehicles. Smart card management is the foundation and direction of the information management of various management systems;
In the user, the non-contact rapid identification of vehicles and the automatic identification and comparison of the user’s identity ensure the safety and protection of personal property, as well as the simplicity and speed of normal entry and exit procedures.
The information source of each sub-management station and the processing terminal of the central management system are combined through a wireless bridge or internal network.
2. System function description
The device is divided into two parts:
One part is the microwave signal identification device (AOSID-0702), that is, the entrance and exit communicator, which can be installed above the entrance and exit of the control vehicle. The other part is an electronic tag. The system equips each parking user with a registered electronic tag, which can be installed in a suitable position in the front windshield of the vehicle. There is an identification code inside the module.
When the vehicle reaches 6-8 meters from the entrance of the community, the vehicle detector detects the existence of the vehicle, starts the entrance communicator, and detects the identity code (ID) in the electronic tag of the coming vehicle. The ID is loaded in the form of microwave and transmitted to Communicator. The ID code in the owner’s electronic tag is preset in the information database of the communicator, indicating that the tag belongs to the parking lot, and the brakes are opened quickly and automatically, and the vehicle can pass smoothly without stopping. The entire system response time Only 0.9 seconds.
2.1 System composition
It is composed of an electronic tag attached to the car body, a transceiver antenna at the entrance and exit of the garage, an AOSID tag reader, a camera controlled and activated by the AOSID reader, an AOSID background management platform, and an internal communication network.
Central control room equipment (computer, management software, etc.)
Entrance equipment (entrance communicator, railing machine, vehicle detector, etc.)
Export equipment (basically the same as entrance equipment)
Electronic tags (same as the number of registered vehicles)

As shown above: the RFID antenna is controlled by the reader to continuously transmit radio waves to search. When the vehicle passes through the warehouse transceiver, the on-board transceiver is triggered and emits code information that can uniquely indicate the identity of the vehicle (such as license plate number, vehicle type) , Vehicle color, license plate color, bank account number, unit name, user name, etc.), and at the same time receive identification inspection, video storage information, the warehouse management station transceiver receives the signal, processed and transmitted to the computer system for data management and Archive for inquiries. Carry out information storage (in-warehouse) or information comparison (out-warehouse), and control the movement of the barriers at the entrance and exit after confirmation.

4. Engineering features
The system has very high automatic control functions, strong anti-interference ability, high accuracy rate, small amount of engineering, strong resistance to damage, wide range of resistance to high and low temperatures, and strong ability to resist oil pollution during the implementation and installation process. The whole system is flexible and maneuverable.
For small single entrance and exit management places, it can be completed by using the single Tao reading system;
For medium-sized management sites, it can be realized by connecting multiple outlets through data transmission lines;
For large-scale management areas, by means of area division, adding readers at the entrances and exits of each area can realize unmanned automatic management of the whole area, and patrol statistics can also be carried out through the handheld readers of security personnel;
For more security considerations, the separation of the two cards of the person and the vehicle (especially suitable for long-term residents), the identification system can only take effect after the comparison and identification of the vehicle card and the master card match, which is a higher level of safety management.
