1. Design plan description
The application of RFID technology in the field of intelligent transportation refers to the organic application of advanced information technology, electronic communication technology, automatic control technology, computer technology, and network technology to the entire transportation management system to establish a real-time, accurate, and efficient Integrated transportation management and control system. It is composed of several sub-systems, which organically integrate roads, drivers, and vehicles through system integration to strengthen the connection between the three. With the help of the intelligent technology of the system, the information of various modes of transportation and road conditions are registered, collected, and analyzed, and through remote communication and information technology, this information is provided to people in need in real time to enhance driving safety and reduce driving time. And guide driving directions. At the same time, managers improve their management efficiency by collecting real-time information of vehicles, drivers and roads, so as to achieve the purpose of making full use of traffic resources.
1. System function overview
1.1 Admission control function: Save manpower: the entrance realizes unmanned management mode;
Identity recognition: Determine whether the vehicle that comes to swipe the card has the permission to enter the venue;
Temporary card issuance: Temporary parking cards are automatically issued to vehicles temporarily entering the parking lot; the card issuance method can choose to have the car button, the non-car button, or the computer; the automatic temporary card reading method can choose the car to read Card, no-car card reader; after the card is issued, the card issuer must wait for the owner to take the card into the hand to open the barrier.

Automatic identification of monthly card: When the vehicle enters, the long-distance reader will automatically read the tag card on the car, and the reader will transmit the information of the monthly card of the vehicle to the background. After comparison, the barrier will be automatically opened, and no entry will be made without an authorized card. . The whole process does not require manual intervention.
Information recording: when reading the card, it will automatically record the time of entry, entry location, vehicle information, and the identity of the vehicle owner; Image capture: capture the image of the entry vehicle in synchronization with the gate opening instruction and store it in the database for vehicle verification and verification when leaving the venue Check later
License plate recognition: Automatically extract the license plate number of the vehicle entering the parking lot, as a unique identification mark for the vehicle entering the parking lot, which can be used for vehicle identification and later reference when leaving the parking lot; full display: when the parking lot is full, pass The LED display screen prompts the coming vehicles, and at the same time prohibits the button to exit the card, but still retains the computer card exit function to meet the entry requirements of some special vehicles and personnel;
Location guidance: prompts and guides vehicles entering the parking lot to park in an area with vacant parking spaces; accurately finding a parking space in a relatively large parking lot is a time-consuming and energy-consuming task, and the parking guidance function can be compared to location guidance The function can solve this problem more accurately;
Information display: High-brightness LED display, even in the sun, the displayed information is still clearly visible; the letter is displayed in both Chinese and English, which is suitable for the increasing number of foreign car owners under the WTO environment; the information content is concise and can be given to car owners Clear reminders, without delaying the time for the vehicles to leave the field;
Voice prompts: convenient and thoughtful voice prompts; clear and pleasant analog voices; pluggable digital voice modules for easy integration in upgrades; large storage capacity to meet the output of a variety of voice prompts; can accurately distinguish between own vehicles and foreigners Vehicles and special vehicles.
