1. Project background
As people’s living standards continue to improve, the total number of cars owned has also begun to grow rapidly. How to carry out efficient, high-quality and intelligent management of the in and out of vehicles within a unit has become more and more important to various administrative departments, enterprises and institutions. The Active RFID-based remote vehicle access control system is at the forefront of the market and has high technical content. Through non-contact information collection and processing of long-distance fast-moving targets, it can realize rapid automatic identification and automatic management of in and out vehicles, which is the most traditional management method. Best upgrade option. Generally speaking, the system will significantly improve service quality and service level for users from the following aspects:
1. Establish a brand new image of property management. The use of modern high-tech products will surely greatly improve the image and popularity of the company’s property management. Adopting intelligent parking lot management system, no matter from the aspect of product styling, or the advancement and scientificity brought by automatic management, it will establish a good image for property management and make the enterprise a model of scientific management.
2. Strict charge management. For the current manual cash charging method, on the one hand, the labor intensity is high and the efficiency is low, and the other main drawback is that the financial loopholes are easy to cause the loss of cash. After using the radio frequency intelligent parking lot management system, all vehicle charges are confirmed and calculated by the computer, which eliminates errors and cheating and protects the rights and interests of parking lot investors.
3. Enhanced safety management. One card for one vehicle, data archiving, to ensure the safety of vehicles parked in the parking lot. When card issuance and card collection are performed manually, it is inevitable that there are omissions because there is no record to check at any time. Lost cars or false reports of lost cars happen from time to time, causing many troubles and economic losses to the parking lot. After adopting the intelligent parking lot management system, consumers of monthly rental cards and stored-value cards have recorded corresponding information in the computer, and the cards can be reissued in time if they are lost.
4. Good anti-counterfeiting performance. Because of the extremely high confidentiality of the RFID card, its encryption function can not be solved by the general computer after ten years, so it is not easy to forge.
5. Durable and reliable, the operation process is fully automated. The active radio frequency identification card used in this system is maintenance-free, has a long service life, is fully sealed, contact-free, dust-proof and waterproof, and does not need to open the gate manually. The system automatically reads and verifies the card and opens the gate, which saves manpower and time.
This system also solves the vehicle management problems faced by various units. It can be applied to the tracking control management of internal vehicles entering and exiting the unit gate, and it can also be applied to the fully automatic and unattended management of internal parking lots. , It is especially suitable for occasions such as the entrance and exit gates of military vehicles, school gates, and power company gates.
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:
3. System advantages:
At present, the system has been successfully applied in a high-end mansion in Haiyan County, Jiaxing, Zhejiang. 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 stop, open the windows, and swipe their cards when they are near the card reader when entering and leaving the parking lot to complete the action of entering and leaving 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;
