With the advancement of society and the development of science and technology, people’s demand for safety protection is becoming more and more urgent. One of the requirements is to implement automatic tracking management of vehicles entering and leaving the company or unit.

Smartkey vehicle entry and exit automatic tracking identification management system is a modern intelligent management system developed to meet this increasing demand of users. The system is developed on the basis of Smartkey’s automatic control technology. It is a high-tech product integrating the world’s most advanced remote card reading technology, computer technology, network technology and mechatronics technology, so as to achieve free entry and exit of legal vehicles. , The purpose of controlling illegal vehicles. The system has good openness and is easy to form a more powerful comprehensive intelligent management system with other systems.

According to the user’s preliminary requirements for automatic computer tracking, automatic identification and automatic control of incoming and outgoing vehicles, a set of automatic identification management system for vehicle tracking is designed based on the principles of convenient use, comprehensive functions, safety and reliability, and strict management.

The vehicles of this unit are all assigned a CENSUS long-distance proximity card. Place a long-distance sensing antenna at the front of the barrier. When the vehicle carrying the proximity card reaches the sensing area, the long-distance card reader reads the card number in the proximity card and transmits it to the controller, and the controller judges the legitimacy of the read card number. If the card is legal, the relay on the controller will act and the smart barrier connected to it will open. If the card is illegal, the relay will not operate, the barrier cannot 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 card reader coil on the other side, the card reader will also read the card number of the proximity card, but it will not output to the controller. Therefore, the barrier will not be opened again (this function is called the same card delay ).

The computer screen installed at the passageway will display the entry and exit information of the vehicle in real time, such as the license plate, card number, photo of the vehicle, entry and exit time, for management personnel to check in time, post-inquiries, and statistics, and can generate various reports .

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.

In order to prevent the barriers of the barriers from smashing the cars due to accidents, ground induction coils are buried under each barrier. A set of infrared beams can also be installed on the left and right sides of the entrance and exit. The barrier itself also has the function of anti-smashing. When the pole is dropped, it will automatically lift the pole when it encounters a certain resistance, thus forming three anti-smashing protections.

U.S. FCC certification
Applications:
It is dedicated to installation on the metal surface of the object, with a reading distance of 2 meters, which can be used as an item tracking card, with a moving speed of up to 60 km/h, 64-bit card encoding, out-of-order encrypted communication, and a misreading rate of less than 1 in 1 billion. The card has no direction limitation, it can be read at any angle of 360 degrees, low frequency work—–no harm to the human body, fully automatic identification, CE, DTI, FCC certification. It is suitable for applications requiring long card reading distance, fast recognition speed, and simultaneous recognition of multiple electronic cards, such as kart timing systems, parking lot management, and automatic vehicle charging management. It is especially suitable for tracking, controlling or positioning items. . Cooperating with CR1A-DS card reader can realize accurate identification of the movement direction of the article, which fundamentally eliminates false appearances.

System plan diagram

Remarks: The card reading distance is 3 meters, and the road width can be 3 to 20 meters. There is no need to stop, and the vehicle speed can reach 60 km/h. Choose TC1A for the sensor card, and stick the TC1A behind the windshield of the car. The CR1A card reader can be connected with an antenna. The antenna can be worn in a stainless steel tube or embedded in a PVC billboard. The antenna can be placed next to the channel. The distance between the antenna and the barrier is more than 6M (depending on the speed of the vehicle entering and exiting, the faster the vehicle speed, the larger the distance should be, so that the vehicle can enter and exit smoothly)

System Features:

1. Long-distance card reading can realize fast entry and exit without stopping. The card is affixed behind the license plate or placed behind the windshield, and there is no need to show the card when the vehicle enters and exits the passage.
2. Multi-card authentication: It can realize that the vehicle can enter and exit the channel only when the vehicle card and the driver card are legal at the same time, which improves the safety of the system.
3. Time control method. The time control for vehicles entering and exiting the channel can be set. For example, vehicles can enter and exit at certain times, but not at other times.
4. Provide anti-passback function and anti-tailing function. When a vehicle carrying a legal card enters the passage, it can enter the second time only after exiting the passage. Prevent legitimate users’ cards from being used by other vehicles and entering the channel. The anti-tailing function is to prevent an illegal vehicle from trailing behind a legal vehicle and entering the passage together before the barrier falls.
5. Real-time vehicle picture display. When a vehicle enters the channel, the computer will display the entry and exit information of the vehicle at the same time for management personnel to browse and check.
6. Card loss report function. Once the card is lost, the lost vehicle card can be reported through the computer.
7. Holiday control.Can be set via software or controller keyboard (time menu) [开门时区表] .The control setting of major holidays, minor holidays, major holidays and minor holidays can be carried out, and the dates of major and minor holidays can be set arbitrarily
8. Open the door remotely. The barriers of the channel can be opened remotely through the electronic map on the computer.
9. Automatic door opening function. The channel barrier can be set to be in an open state in a certain period of time. Such as vehicular traffic peak.
10. Work offline. In order to ensure the safety of the system, the controller can work independently of the computer. In the case of network interruption, the entry and exit information of the vehicle is stored in the controller. Once the network is restored, the record of the controller is automatically uploaded to the computer.

Option 2: (Using buried antenna, the card is fixed behind the car license plate or directly in the door pocket, the bottom of the car, the card is TC3A)
