The Radio Frequency Identification Technology-based Design And Development For Electronic Domestic Animal Scale

The technique of Radio Frequency Identification is a kind of automatic identification technology, rising and mushrooming since 1990s. RFID technology automaticly identify the target and acquire the correlative data through radio frequency signal, and the biggest advantage lies in its recognition without human intervention, which can work in all kinds of adverse circumstances.Based on the full awareness and understanding of RFID, this paper take the animal fine cultivation system as the information platform, and build a set of information gathering, weighing and wireless data transmission. as one of the livestock scale electronic system.Main work in this paper:1) Based on RFID technology, I complete the electronic livestock scale system hardware. In order to guarantee the read-write best condition and greatest distance sensors of RFID, this paper choose the ISO15693 standards for RFID equipment and design the antenna size after several experiments.2) Based on the development of electronic livestock scale software systems of RFID technology, I completed its software development, parameters set and system interface development and so on, and achieve the communication between computer and reading, as well as computer and weighing instrument.3) In order to ensure the security of information systems, I encrypt the label using DES arithmetic, and complete the encryption arithmetic using the C language.The work of the paper have some meaning to similar application based o RFID.
