As an important technology in the Internet of Things, RFID has received extensive attention and research in recent years due to its low cost, security and high efficiency. In this paper, an intelligent vehicle management system based on UHF RFID (ie, car networking) is proposed. The system consists of RFID hardware system, CDMA system, GIA system and data processing system, which can realize intelligent identification, positioning, tracking, speed measurement, monitoring and management of vehicles to solve the current severe road congestion, vehicle overspeed overload and vehicle theft. And the management of official vehicles and other issues.
0 Preface
With the development of economy and technology, the number of car ownership in China has increased year by year. The increasing number of vehicles has brought severe challenges to today's vehicle management: car congestion, vehicle theft, difficulty in identifying vehicles, and frequent traffic accidents caused by speeding. hair. How can we use scientific and technological means to effectively utilize road resources and keep roads open; clarify vehicle identity so that units can effectively manage vehicle entry and exit; curb vehicle overspeed and overload, ensure vehicle safety; improve vehicle "self-defense" level and prevent vehicle theft; transparent Official vehicle identity information, limiting the private use of official vehicles? This paper proposes a solution to the above problems based on UHF RFID, GSM, GIA intelligent vehicle management system. Part 2 of this paper describes the intelligent vehicle management system to identify inbound and outbound vehicle identity on a closed university campus to enhance management of access to and parking of campus vehicles. The third part describes the intelligent vehicle management system to collect road information in real time in the open road network, so that the traffic department can optimize the traffic flow and rationally allocate the road resources; and locate, measure, track and identify the dangerous vehicles. take. The fourth part combines the current situation of replacing the new military card with the whole army and the armed police force, and puts forward the idea of ​​replacing the new RFID smart license plate and using the intelligent vehicle management system in the country, and expounds the solution of the system to the current vehicle management problem.
1 Vehicle identification and management subsystem applied to enclosed areas
The university is a relatively open environment. The complexity of vehicles in the university area and the dispersion of vehicle management have brought hidden dangers to the life and property safety of university teachers and students. Especially in 2010, Hebei University was shocked by the people. My dad is Li Gang. The incident has made it more important to rectify the order of the campus, strengthen the management of vehicles entering and leaving the park, and ensure the safety of teachers and students.
1.1 Status of Vehicle Identification System
At present, the vehicle management of some universities adopts manual discriminant: that is, the school will issue a paper sign to the vehicle of the unit, and the guard will identify whether the incoming and outgoing vehicles belong to the unit, and the foreign vehicle will go to the designated place for temporary access procedures. This method is not only inefficient, but also has a long delay in inspection. It is also because it does not use technical means to prevent forgery, which has hidden hidden dangers for forging signboards.
Another part of the university uses an inductive IC card access management system. Although the card is safe and confidential, not easy to be counterfeited, easy to carry, and durable, the conventional IC card itself is a proximity proximity card with a reading distance of only a few centimeters. In actual use, the owner needs to stop the vehicle, shake the window, hold the IC card out of the window, swipe the card, and then continue to enter and exit. Compared with the previous management system, the vehicle access management system takes longer time during the inspection period and does not bring convenience to the owner, especially in the weather of rain and snow, hot weather and the like, making the owner more inconvenient; The IC card vehicle access management system essentially requires parking, and it cannot achieve more advanced and user-friendly accessibility.
