1. Introduction to the system
In response to the needs of high-end communities, enterprises, and institutions for intelligent parking lots, Yuanwanggu launched an intelligent parking lot management system that integrates computer technology, short-range microwave communication technology, image digital processing technology, and automatic control technology to achieve automatic vehicle identification and Information management improves the efficiency and safety of vehicle traffic, and counts vehicle entry and exit data to facilitate management personnel to dispatch, so as to reduce the labor intensity of management personnel and effectively prevent toll loopholes.
2. System composition
Electronic license plate (store corresponding vehicle information), driver card (optional, store corresponding driver information, mainly for the purpose of strengthening supervision), access control antenna, remote reader, access controller, access control computer, software including management Software and card writing software.
3. System workflow
When the vehicle enters/exits the access control antenna communication area, the antenna uses microwave communication to exchange two-way data with the electronic identification card, read the relevant information of the vehicle from the electronic car card, and read the relevant information of the driver from the driver card , Automatically recognize the electronic vehicle card and driver card and determine whether the vehicle card is valid and the legitimacy of the driver card. The lane control computer displays the license plate number and driver information corresponding to the electronic vehicle card and driver card one-to-one; lane control computer The relevant information of passing time, vehicle and driver is automatically stored in the database, and the lane control computer judges as follows based on the data read:
◇ Normal card: When the license plate number and driver card read are legal, the movable door opens automatically (4 meters), and the movable door closes automatically after the vehicle leaves the coil 1.
◇ Unauthorized card: When the read card or driver card is unauthorized, the system will alarm and capture and save the picture, and the movable gate will not open;
◇ No truck: When the vehicle triggers coil 2 and the system does not read the vehicle card and driver card, the system determines that there is no truck, the system alarms and captures and saves the picture, and the movable door does not open;
◇ Illegal card: a card that is not from the company, although the data is read by the card reader, but not from the company, the system alarms and captures and saves the picture, and the movable door does not open.
Four, system characteristics
This intelligent parking lot system is a computer network composed of a management system and a channel identification system, and the network communication protocol adopts the TCP/IP protocol. This system can effectively, accurately and intelligently identify, collect, record and park the data information of system vehicles (vehicles with electronic license plates) and non-system vehicles (vehicles without electronic license plates) entering and leaving the parking lot. , Upload, process, and when necessary, can be supplemented by corresponding manual intervention to avoid the impact of abnormal events (when non-system vehicles enter and exit), and to ensure that the access control system has efficient vehicle intelligent release capabilities.
In addition, through correct design and installation, only the same frequency point can be used to complete the non-stop traffic of vehicles on many lanes at the same time without interfering with each other.
