1 System background
1.1 Status analysis
With the development of science and technology and the increasing improvement of people’s living standards, the number of vehicles in the society is constantly increasing, which makes it more difficult for many units to manage the entry and exit of vehicles. For internal security, it is more urgent to regulate the management of all types of vehicles entering and exiting. It is necessary to ensure the rapid entry and exit of vehicles of the unit, while also taking into account the management and monitoring of external vehicles. These tasks are difficult to perform by relying on manpower alone. The previous manual management methods have high labor intensity, complicated approval procedures, manual delivery forms with many loopholes and difficult to inquire, inaccurate entry and exit time records, low efficiency, and high error rates, etc. Mistake.
In the past, the “iron license” management implemented by the government was difficult to investigate one by one and to identify the authenticity; it is difficult to identify whether the local license plate of the cadre himself and his family members is an in-house vehicle or a temporary visiting vehicle, and even if there is a parking permit, it is sometimes difficult to distinguish the authenticity; Management personnel have long been troubled by related issues such as the difficulty in distinguishing forged license plates of visiting vehicles. Therefore, the use of modern technology to manage vehicles is an inevitable trend of social development.
1.2 Advanced technology
Since its establishment, Huibang Technology has been focusing on the research and development of RFID (radio frequency identification) technology, and is committed to applying high-tech products with independent intellectual property rights in government administration, financial industry management, petrochemical industry management, automobile manufacturing management and agriculture Promotion and application of industrialization management and other fields. 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 to make unit vehicle management enter the automatic control stage. The vehicle identity can be automatically identified through the issued unique electronic identification card of the vehicle. Automatically judge the legitimacy of the vehicle according to the recognized electronic card information, automatically display the vehicle status on the monitor installed at the door, and have a real-time alarm function. It realizes convenient management of vehicles, and has the characteristics of high reliability, high recognition rate, and easy installation and maintenance. Reduce manual intervention, automatically complete a series of on-site data collection, comparison and control tasks, save manpower, improve work efficiency, and reduce human errors and illegal release. At the same time, it also provides a high-tech protection for the safety of the entire organization. So as to achieve the purpose of free entry and exit of legal vehicles and control of illegal vehicles.
2 System introduction
The RFID vehicle entry and exit automatic management system adopts long-distance radio frequency induction technology, which can realize the automatic management of vehicles entering and exiting the provincial government compound. The system uses the wireless communication between the electronic tag installed on the vehicle and the reader at the entrance 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 prevent the entry of idle vehicles. The system can quickly collect and record vehicle information during the vehicle entry process, thereby improving the efficiency of vehicle entry and exit, and enhancing the image of the provincial government.

2.1 Design ideas
A unique corresponding electronic identification card is issued for the vehicles of provincial government employees. The card is fixed behind the license plate of the vehicle to prevent problems such as changing the license plate.
Set a speed bump in front of the provincial government gate. When a vehicle wants to enter the agency gate, the front camera will monitor it and capture the license plate of the vehicle, and then compare it with the license plate data in the card reader set. If it is not legal for centralized entry by card reader The license plate, the system alarms at this time. It realizes the capture and recognition of vehicles one by one, solves the problem that many vehicles enter the reading range of the card reader at the same time, and it is difficult to distinguish which vehicle has an alarm, and prevents illegal vehicles from following legal vehicles into the phenomenon.
Vehicles that enter the reading range of the card reader will automatically send a message when entering the gate entrance. At this time, the card reader will read the card information and send the read information to the system center for information verification and judgment Whether the information of the vehicle and the card is correct, the display will reflect which state the vehicle belongs to, and a corresponding alarm sound will be issued to remind the staff.
The application of this system not only solves the problems of the provincial government in the past that it is difficult to supervise the entry and exit of personnel, it is difficult to control and manage vehicles only by manual inspection of iron plates, and the management is time-consuming and labor-intensive. At the same time, it effectively prevents the emergence of emergencies.
2.2 System composition
This system is mainly composed of RFID (radio frequency identification) vehicle smart identification card, card reader, camera, LED display and voice alarm device. Here are a few main components:
2.2.1 Vehicle Intelligent Identification Card
The vehicle smart identification card is a legal mark pasted on the vehicles permitted by the provincial government. The automatic identification system will use it to read vehicle information from a long distance to determine whether the vehicle has passed. It carries the function of vehicle electronic information that can not be copied and can be identified at a long distance. The ID number inside the electronic tag is unique in the world, and there is no copy.
The vehicle smart identification card uses the passive 915MHz frequency band, which follows the EPC/ISO 18000-6B, C international standard. As we all know, due to the strong refraction of the active signal at 2.45GHz, it is impossible to achieve close-range single-vehicle management. For this reason, the company uses passive 915MHz to achieve short-distance targeted bicycle management. This frequency band can identify and manage a single vehicle within 0-5 meters.
We can paste the vehicle smart card behind the license plate of the vehicle, and read its information when the vehicle enters the reading range of the card reader. Vehicle smart cards have the characteristics of anti-counterfeiting and anti-disassembly. It can be combined with the license plate to prevent the occurrence of license plate exchange and forgery.
The label uses a unique 64-bit serial number that is unique in the world, and the card cannot be rewritten. It can be read more than 100,000 times continuously, which can completely guarantee that it cannot be forged. At the same time, the chip of the vehicle identification card adopts advanced chip-level anti-dismantling technology. Even if the disassembled chip is repaired and restored with exquisite circuits, the system can still determine that the card is an illegal card and track the disassembled label.
The vehicle intelligent identification card has excellent anti-interference ability, stable wireless signal transmission power and excellent resistance to signal interference in the 0.1-1000MHz frequency band under all-weather conditions. The tag must not interfere or conflict with the existing equipment on the car (such as GPS, etc.). It not only has excellent anti-interference ability, but also has high security and reliability. Through encryption algorithm and authentication, it ensures data security and prevents link eavesdropping and data cracking.
The vehicle’s intelligent identification card is solid-state packaged, and it is lightning-proof and waterproof to meet the requirements of the industrial environment. It can still work normally between minus 40 degrees and minus 60 degrees, so it can adapt to temperature changes from -30°C to +60°C. The service life of this card is more than 10 years.
2.2.2 Reader
The card reader equipment used by Huibang Technology can be used by customers in harsh environments, and can adapt to the constantly updated needs and provide new technologies that are advancing with each passing day. We provide card readers specially designed for outdoor operations, which can withstand multiple drops from a height of 5 feet (1.5 meters) to a smooth concrete floor without failure.
Based on six years of R&D experience in card reader equipment, its built-in RFID read-write module and built-in GPRS module are more practical and work well in rain, snow, and sun. No adverse phenomena occurred after testing.
2.2.3 LED display and sound alarm
The computer screen installed at the gate will display the vehicle’s entry information and the legal status of the vehicle in real time, such as the vehicle’s license plate, card number, vehicle photo, entry and exit time, and whether it is normal, so that management personnel can check and inquire afterwards in time , Statistics, and can generate various reports.
The sound alarm can prompt the staff in time, and respectively send out different alarm sounds according to the state of the vehicle at the gate entrance, so that the management is more convenient and faster.
3 System function
● Vehicles can only enter the passage with a legal card installed.
●Remote card reading can realize fast entry without stopping. The smart identification card is affixed to the back of the license plate of the vehicle, so there is no need to show the card when the vehicle enters the gate.
●Provide anti-tailing function. In order to prevent an illegal vehicle from following a legal vehicle to enter the gate together, we installed a camera near the speed bump to capture the entering vehicle in time and investigate the illegal vehicle.
●Real-time display of the legal status of the vehicle and sound alarm, the vehicle with a legal smart identification card will display the license plate number and other information on the LED display at the door after the information is read by the card reader, and the vehicle status will be displayed at the same time. There are the following three types: Normal: This car is equipped with this card; Abnormal: This car is equipped with another card; Alarm: This car is not equipped with a smart identification card, which makes staff management more intuitive and faster. Solve the problems of difficulty in troubleshooting and slow inspection in the past.
●The system can be used online or offline (when the network is interrupted). When the management software is started, the card swiping record is stored in the controller and uploaded automatically.
●The unit vehicles can be counted. Since the vehicles will be automatically recognized by the reader when they enter the gate, the number of vehicles entering the courtyard can be counted in real time.
4 System superiority
■High reliability-can deal with a variety of tests
If the system is interrupted by a system failure or other accident, the accuracy and completeness of the data can be ensured through the storage function of the reader; the system has a high card reading rate and is not easily affected by the weather environment and other factors.
■Strong practicality-anti-replacement license plate
The use of RFID technology, combined with the license plate recognition technology, can eliminate the cheating method of replacing the license plate. This system issues an RFID electronic tag for each vehicle that needs to be managed. If the license plate is fraudulent (without a smart identification card), even if it passes the camera capture Recognized, but the card reader cannot receive the information, the system warns that the car has no card. Basically solve the problems of vehicle management on the side of the road interference, vehicle trailing, vehicle license change and so on.
■High security-anti-counterfeiting and anti-disassembly
Each RFID electronic tag has a unique ID number in the world, and it cannot be modified or copied. Therefore, RFID technology has unparalleled anti-counterfeiting performance. In the RFID tag, the license plate number and license information can also be encrypted and written into this area, which has a high anti-counterfeiting feature.
The chip of the vehicle smart identification card adopts advanced chip-level tamper-proof technology. Even if the disassembled chip is repaired and restored with exquisite circuits, the system can still determine that the card is an illegal card and can track the disassembled label. The card cannot be disassembled or stolen, preventing the occurrence of incidents where someone wants to steal the card and enter the door.
■Wide applicability-to meet the needs of social development
The application of this system has changed the old access management mode of government agencies and enterprises, which can greatly enhance the image of management institutions and meet the requirements of modern management.
