Suzhou Luhe Electronic RFID intelligent vehicle access management system without reaching out has been successfully launched in a high-end mansion in Haiyan County, Jiaxing, Zhejiang. The system has the following advantages:
The management of traditional parking lots basically adopts passive IC cards to realize parking access authority and fee deduction management.The system requires customers to approach the parking lot when entering and leaving the parking lot.Card readerOnly by parking nearby, opening the windows, and swiping your card can you complete the movement of entering and exiting the parking lot. This puts forward higher requirements for drivers, no matter where they are, in good or bad weather, they must park in a fixed position and open and close the windows. According to the limitations of the above-mentioned system application, in order to improve the level of service to customers and the management level and efficiency of the parking lot, Tangyuan Electronics used its own technical advantages and combined with the actual requirements of the site to launch a long-distance parking lot management system.
1. Save manpower, improve work efficiency and economic benefits;
2. Automated design, fast vehicle entry and exit, improve grade and efficiency, and provide high-quality, safe and automatic parking services;
3. It can accurately distinguish between free vehicles and foreign vehicles;
4. Show the company’s integration strength;

2. Overall system construction plan
2.1 The working principle of the system
The tag is placed in the car. When the car is near the door of the unit, the tag will be activated by the 125K signal from the ground line of the low-frequency activator.
After activation, the 2.4G signal of the tag is in working state at this time, and 2.4G signal (ID number) is sent out. After receiving the 2.4G signal (ID number) of the tag from the long-distance omnidirectional reader next to it, the relay in the 2.4G long-distance omnidirectional reader device will work and give a switch signal for the control of opening the door. After the control board receives the switch signal from the 2.4G long-distance omnidirectional reader device, it will actively send voltage to the door opening motor. At this time, the door opening motor works to open the entrance and exit unit doors.
After the vehicle leaves the unit door and leaves the 125K low-frequency activation area, the 2.4G signal of the 2.4G electronic tag stops working. After the 2.4G long-distance omnidirectional reader cannot read the 2.4G electronic tag, the 2.4G remote reader The relay will stop sending the switch signal to the control board. At this time, the door opening control board will stop sending the door opening voltage to the unit door motor. The door opening control board will automatically give a door closing voltage, and the unit door will automatically close.
2.2 System topology
The vehicle entry and exit management system can adopt various network topologies. The server and the management workstation are connected in the form of a local area network (LAN), and the computer is connected to the lower computer by RS485 bus type; it is simple, quick to put into use, and the system is stable. The highest rate of return on investment. The block diagram of its topology is as follows:
2.3 Network topology diagram
For the entrance and exit control system, the server is responsible for the important task of the entire system. The rapid access of data is a problem worthy of concern, but the safety of the data cannot be ignored. Once the hard disk fails or the data is lost or damaged due to improper operation, it will The entire system enterprise will have a huge impact on the system. It can be seen that the value of the data stored by the server far exceeds the value of the machine itself, and the SQL server selection cannot be ignored. The vehicle management system with the entrances and exits together only needs a computer to manage it. If the entrances and exits are separated and there are many temporary vehicles, it is best to place a computer at each entrance and have a security guard on duty. In order to deal with emergencies.
The first level network is RS485 bus system distribution, which mainly provides communication for each entrance and exit control machine, and the card reading data is taken; the second level network is LAN Ethernet star connection, computer and computer communication and data storage, SQL server is responsible for Data query and processing, distribution of network resources, and classification review of the authority of each workstation.
