RFID-based agency unit access control system

1 system background

1.1 Analysis of the status quo

With the development of science and technology and the improvement of people’s living standards, the number of social vehicles continues to rise, which makes the management of vehicles entering and exiting many units more difficult. In particular, various government agencies have frequent access to vehicles, and personnel are complicated, in order to protect them. For internal safety, it is more urgent to regulate the various types of vehicles that enter and exit. It is necessary to ensure that the vehicles of this unit can enter and exit quickly, and at the same time, it can take into account the management of foreign vehicles. It is difficult for these jobs to rely solely on manpower. In the past, manual management methods were labor-intensive, and the approval procedures were complicated. Manually filled out vehicles had many vulnerabilities and were not easy to query. Inaccurate entry and exit times were inaccurate, inefficient, and resulted in high error rates. error.

In the past, it was difficult for the “Iron” brand management implemented by the government to check one by one and to distinguish between true and false. It is difficult for local licensees of cadres and their families to identify vehicles belonging to the hospital or temporary vehicles. Even parking permits are sometimes difficult to distinguish; The related problems such as the inconvenient identification of visiting vehicle forged vehicle license plates has long plagued managers. Therefore, using modern technology to manage vehicles is an inevitable trend of social development.

1.2 Advanced Technology

Since its inception, Huibang Technology has been focusing on the research and development of RFID (radio frequency identification) technology and is committed to the high-tech products with independent intellectual property rights in government administration, financial industry management, petrochemical industry management, automotive manufacturing management and agriculture. Industrial management and other areas of the promotion and application. The R&D and application of RFID technology in various fields has brought convenience to our lives and brought us into the next technological era.

This system combines RFID technology and license plate recognition technology so that the unit vehicle management enters the automatic control stage. The identity of the vehicle can be automatically identified through the vehicle's unique electronic identification card. Based on the identified electronic card information, the vehicle automatically determines the legality of the vehicle, automatically displays the vehicle status on the monitor installed at the entrance, and has a real-time alarm function. To achieve the convenient management of vehicles, with high reliability, high recognition rate, easy installation and maintenance. Reduce manual interventions, automate the collection, comparison, and control of a series of field data, save manpower, increase work efficiency, reduce human error, and release regulations. At the same time, it also provides a high-tech protection for the safety of the entire organization. In order to achieve the purpose of free entry and exit of legal vehicles and control of illegal vehicles.

2 System Introduction

RFID remote access radio-frequency induction technology is adopted in the automatic management system of vehicles entering and leaving, which can realize the automated management of vehicles entering and leaving the provincial government compound. The system uses the wireless communication between the electronic tag installed on the vehicle and the reader/writer at the gate of the compound (and can be used in conjunction with the license plate recognition system) to determine whether the entering vehicle is a legal vehicle and prevents the entry of a noisy vehicle. The system can quickly collect and record vehicle information as the vehicle enters the process, thereby improving the traffic efficiency of vehicles entering and exiting and improving the image of the provincial government.

2.1 Design Ideas

A unique electronic identification card is issued for the provincial government’s vehicles. The card is fixed behind the license plate of the vehicle, which can prevent problems such as the exchange of license plates.

Set a deceleration zone in front of the provincial government. When a vehicle wants to enter the gate of the organization, the front camera monitors it and captures the vehicle license, and then compares it with the license plate data in the reader's card set, if it is not legal for the centralized reading of the card reader. License plate, at this time the system alarm. The realization of one-by-one capture recognition of vehicles solves the problem that more vehicles enter the read range of the reader at the same time, and it is difficult to distinguish which car has an alarm, which prevents the occurrence of non-legitimate vehicles following the entry of legitimate vehicles.

A vehicle entering the reading range of the reader will automatically send out information when entering the entrance of the gate. At this time, the card reader will read the information of the card, send the read information to the center of the system, check the information, and judge The information on the vehicle and the card is correct, the display will reflect the status of the vehicle, and a corresponding alarm sounds to alert the staff.

The application of the system not only solves the problems that the provincial government used to control the accessibility of personnel, but also that it is difficult to control and manage the vehicles manually by using iron cards, and it is time-consuming and labor-intensive to manage. At the same time, it effectively prevents the occurrence of emergencies.
