Electronic Official Locks System Base On IButton Technology

Along with living standard enhancement, the people are more and more high to the work and the life quality pursue. The intellectualized product walks into people's work life gradually. The iButton electron office locks system is a work intellectualization important tendency. This article is precisely research and development of the project of"iButton electron office locks system"as a background, unifies author's design idea, the actual design attainment completes emphatically.The paper first was brief introduced the iButton electron office locks concept and background; then introduced the function of iButton electron office locks system , as the structure and the model application; in the third chapter, analysised system structure and given the system design proposal, including: the design of iButton electron locks supervisor and the portable electron lock manage stick, as well as the introduction of the function of the manage software; In next various chapters, introduced the design of the system, includes the realization process of each key technologies.First is in the system corresponds the main bus network design, including: 1-Wire bus, I2C bus, RS-485 and RS-232; Then introduce the circuit design and software design of iButton electron locks controllers and the portable electron lock manage stick; Finally introduced in the system uses verification technology and anti-jamming technology.
