As we enter the 21st century, China is entering a period of rapid development in the national economy. With the improvement of people's living standards, the total number of cars has begun to grow rapidly. How to carry out efficient and high-quality intelligent management of the vehicles in the parks under its jurisdiction has been increasingly valued by various administrative departments and enterprises.

Tsinghua Tongfang's remote vehicle access intelligent management system developed by RFID radio frequency identification technology has effectively solved the vehicle management problems faced by various units. It is applied to parking lot charge management and vehicle control. The owner can enter and exit the parking lot without stopping. Through the computer to automatically identify the cardholder identity, determine whether the car is released or intercepted, providing great convenience for car owners and property management.
This product is at the forefront of the market and has high technical content. It realizes automatic identification and automatic management of incoming and outgoing vehicles by non-contact information acquisition and processing of long-distance moving targets, which is the best upgrade option for traditional management methods.
system structure
The system is mainly composed of entrance card reader controller equipment, entrance railing machine, exit card reader, export railing machine, charging and monitoring management center.
System functions
1. Long-term, temporary user management
Long-term user and temporary user management, including the preservation and registration of basic information of long-term users, basic information management of temporary user IC (ID) cards, registration, renewal, cancellation and loss reporting for long-term users, can be set according to local price regulations Reasonable fees.
2. Vehicle access control management
When a long-term user vehicle enters the market, the card reader senses the user card and automatically determines whether it is valid (expiration judgment, anti-detour judgment) card. If the effective railing is automatically lifted, the car enters the stadium, and the railing automatically falls after entering the stadium. The vehicle enters the vehicle; when the vehicle is on the scene, the user drives to the range of the outlet reader, and the card reader automatically determines whether it is valid (expiration judgment, anti-detour judgment) card. If the effective railing is automatically lifted, the car will appear. After the appearance, the railing will automatically fall and complete a journey.
When the temporary user vehicle enters the market, the card is picked up at the entrance card issuing device, the card is swiped at the card reader, the railing is automatically lifted, the car enters the hall, the railing automatically falls after entering the stadium, and the entering process is completed; when the vehicle is on the scene, the user drives the car. To the exit, the card will be handed over to the export toll collector. The export toll collector will swipe the card on the card maker. The computer will automatically calculate the amount due according to the charging standard, and display it on the amount display. After the user pays the fee, click the “release†railing to automatically lift. From the beginning, the car appeared, the railing automatically fell after entering the stadium, completing a journey.
3. Image comparison
The color camera of this system is installed at the entrance and exit. When the vehicle enters the card to read the card, the image of the vehicle is taken. After processing by the computer, the information of the card held by the owner is stored in the computer database. When the vehicle is on the scene, the camera system works again, taking the appearance of the vehicle, recalling the image when entering the scene, and displaying it on the computer screen to confirm that the vehicle is effectively stolen. Managers can monitor the status of the exit at any time. Images of fixed users and temporary vehicles entering and leaving the parking lot are saved for use in the inquiry.
4. Parking guidance system
Parking lot guidance is currently mainly to install parking space display cards, which show whether the parking lot has space and its number, generally installed at the entrance. If the parking space is full, the driver can find another parking lot. Such a function is relatively simple and easy to implement. Image comparison and parking guidance systems are optional features.
System Features
1. Vehicle passing quickly through/out
Long-distance identification technology is adopted, and other short-distance technologies are supplemented. The distance can reach 4-6 meters, and the anti-interference ability is strong and the anti-counterfeiting performance is good. The card reading operation can be completed within 0.2 seconds, which is convenient for the user to use; the detection speed of the vehicle through the entrance and exit communicator is above 10KM, and the vehicle can be stopped.
2. Out/at entrance unattended
The long-term user exit/entry can be unattended. If a special situation occurs, the driver can contact the central attendant through the intercom system inside the card reader to solve the problem of the driver's parking in time, and keep the entrance and exit unimpeded. The modern management of the parking lot can also reduce the number of managers.
3. Good safety and anti-interference
Using advanced signal processing technology, the signal has strong anti-interference ability. The high-energy battery in the identification card provides sufficient voltage and function for the normal operation of the integrated circuit and the transmission of high-frequency electromagnetic waves. The energy consumption of the identification card is extremely low, and each card can be used for 6-8 years.
4. Multiple card reading distances
The system provides three kinds of alternative equipments: short distance, medium distance and long distance. It can be used without stopping at a long distance, with high speed and large flow. At medium and close distances, it can travel slowly.
