I. Introduction
With the progress of society and the rapid economic development, people’s lives have undergone tremendous changes, and there are more and more transportation vehicles. The management of personnel and vehicles in enterprises and units is also complicated and cumbersome. This inconvenience also forces enterprises to find effective management system tools. The intelligent personnel and vehicle access management system is a high-tech product produced in response to such needs. It not only can effectively simplify the approval steps for personnel and vehicle access, but also can automatically recognize the identity of personnel and vehicles in a humanized manner, making the management of personnel and vehicles simple , Accurate, and can improve the image of the company.
2. System overview
The personnel and vehicle entry and exit management system is an intelligent management system with international leading level developed based on the management needs of enterprises and institutions, personnel entering and exiting vehicles, using long-distance radio frequency identification technology and automatic control technology to achieve convenient personnel and vehicle entry and exit. The purpose of fast speed. It will play an important role in improving corporate image and management and service levels.

The second part of the system function
Fully automatic identification management system function
The employee’s vehicle is issued a remote identification card, which is fixed on a certain part of the vehicle (such as the front windshield glass). A remote sensor is buried in the ground at the front end of the barrier. When the vehicle carrying the RFID smart card arrives in the sensing area, the remote card reader reads the RFID smart card number and transmits it to the controller. The controller reads the card number Perform legality judgment. If the card is legal, the relay on the controller will act and the smart barrier connected to it will open. If the card exceeds the authority, the relay will not operate, the barrier will not be opened, and the computer will give an alarm message of an illegal card.
When the vehicle passes through the barrier, the barrier will automatically fall. When passing the exit antenna, the card reader will also read the card number of the proximity card, but it will not output to the controller. Therefore, the exit barrier will not be opened. The company adopts intelligent barrier gates at the entrances of the company. After receiving the door opening signal from the controller, the barriers are automatically opened; after vehicles pass by, the bars are automatically dropped.
The third part of the system advantages
1. Stability and high reliability
This system adopts long-distance sensing products, which has the characteristics of long sensing distance, fast reading speed, multiple identification, etc. From the many important parking lots that have been installed and the actual feedback of users, it can be seen that this system has high stability and reliability.
2. A brand new corporate management image can be established
In the past, the vehicle access management system used proximity sensing or contact IC cards. The owner had to stop and swipe the card or open the window to bring the card close to the card reader to swipe the card, which was not only inconvenient but also slow in response speed of the system. This system uses a long-distance sensor card (1-3 meters), which can realize non-stop inductive traffic (60KM/hour), so it will bring convenience and practicality to the driver. The brand-new management concept will surely greatly improve the management image and reputation of the enterprise unit, and bring the enterprise’s automated management to a new level.
Three, high security
One car, one card, data archive. Ensure the free entry and exit of foreign vehicles, and ensure the safety record of off-line test runs. After adopting the automatic control management system, vehicles enter and exit units with cards, one card for one vehicle, and the computer automatically controls the entire process of vehicle entry and exit, eliminating many inconveniences caused by human control, so as to achieve the purpose of automatic, fast, convenient and safe management.
Four, high anti-counterfeiting
In the past, repetitive codes always appeared in the process of issuing the proximity card. Heavy trucks will cause system insecurity during use. The card number of the proximity card is composed of HID and PID codes. Strict management at the factory to ensure the uniqueness of the card number, the communication between the card and the card reader adopts a unique encryption method, which effectively prevents the duplicate code phenomenon of the card and the card being copied.
5. Applicable and reliable
This system uses our company’s low-frequency radio frequency automatic identification card. The proximity card has a full range of varieties and is suitable for applications in different fields. The appearance is all sealed, dustproof and waterproof. The service life is more than 3 years, working temperature: -20～+60℃.
Six, computer management
The system adopts computer management, and the relevant information of each user’s vehicle is stored in the computer, such as: license plate number, car model, color, vehicle photo, owner’s name and other information. When the vehicle enters and exits, the relevant file information is automatically transferred to the computer screen, which is convenient for the staff to supervise.
System composition (picture)
Intelligent vehicle management system process
Install RFID readers, cameras, ground sensing coils, LED display screens, etc. at the entrances and exits of each unit, and install RFID electronic tags on each motor vehicle and non-motor vehicle to read remote information to verify whether the vehicle is The vehicles of this unit shall be released or registered, and the system will automatically report to the police in case of illegal use of the vehicle.
work flow chart)
Intelligent vehicle management system function
(1) Realize the function of fast entry and exit without stopping, and realize unmanned management of internal vehicles;
(2) The self-guided function of parking spaces according to the regulations of the vehicles, realizing one-to-one vehicle and parking spaces;
(3) Judging whether it is a legal vehicle or a stolen vehicle based on the ID number of the vehicle;
(4) Install electronic tags on the vehicle, which is safe, convenient and durable;
(5) External vehicles use RFID electronic tags, which is convenient for registration and tracking;
(6) With LED Chinese display: display welcome message, vehicle number, parking location and other admission guidance information.
