Reverse Car Searching System Based On RFID Dual Frequency Tags

The constant expansion of the parking lot, large orvery large car park which allowpeople how to find their own car in the parking lot quickly become a problem. How tohelp users quickly find their car in the parking lot is the main work of this paper.Research the current reverse car search technology, such as credit card positioningtechnology, positioning equipment layout density-dependent costs; reverse car searchbased on visual recognition technology, higher plate correctness,The license plate isobscured, or not clear positioning less effective; Wi-Fi to find car technology, poorsignal stability. This paper presents a new method to solve the difficult problem-troubled bythe majorityofusers find his car and dual-band RFID tag technology-basedreverse.The underlying design, the system uses RFID (radio frequency identification)technology to achieve the positioning function, it has no manual intervention, withoutdirect contact, better detection in harsh environments, the method and the use ofdual-band RFID tagspositioning, and effectively improve the positioning accuracy andefficient device for use; The design of the application layer, combined with the designmethod of software engineering: effective integration the serial reader module, datatransmission module, positioning module, car locator module and integrate in carlocator module, improved navigation car locatormethod, effectively improve theefficiency of searching cars, shorten the time users spend searching cars; Thepositioning module positioning method the validity of the test, the user tolerancedistance to do the research, so that the system is designed to better respond to the needs of users.Virtual testing in the latter part of the work by creating parking model, but also theuse of the parking lot of the schools within the actual test, test data show the feasibilityand effectiveness of the system design methodology.
