| Summary: | 碩士 === 北台灣科學技術學院 === 機電整合研究所 === 96 === The RFID firmware interface for single packet fast alignment and its application in the intelligent parking management are proposed in this thesis. There are three parts in this system: software management program, firmware identification interface and hardware electronic circuits. The major idea is that the identification tag number is transported from RFID card to software management program for alignment checking, and only one set password is packed and conveyed to the firmware decoder when the identification number is checked up and confirmed rightly. Finally, the single password packet is decoded by the firmware decoder, and then the hardware circuits will transport a logic permission signal to drive a motor on in order to open the gate.
The database, which is saved in a servo compute, is shared for software program using in the same local area network. The software management includes the parking management and electronic wallet function. It can read or write trade records in RFID card. A fast comparative method also proposed in software program, in which the identification number is divided into an address set and a password set and then they are aligned for fast comparing. The parking management system also includes the electronic wallet, which can record trade information in some sectors of RFID card. Besides, a web camera takes the pictures in the input and output zones for saving image data.
The hardware includes Schmitt Trigger and the optical coupler transistor circuits. It can resist electronic noises and isolate magnetic disturbances. The optical coupler transistor circuits and common relay switch circuits take the place of solid state relay (SSR) in our design, which not only can saves hardware price but also can isolate magnetic disturbances. There is an infrared ray in the gate, which confirms weather a vehicle or article is below the gate or not. The gate also can be remote controlled for emergency. Besides, only one set password packet and fast checking methods are utilized, so safety and fast alignment will be included in the proposed firmware RFID system.
