The Application of iButtonTM MicroLAN in Automatic Key Management System BAI Yan , ZENG Guangyu (PLA Institute of Information Engineering, Information Engineering University, zhengzhou,china 450002)
【Abstract】 The MicroLAN is a master-slave network using a single data line plus ground reference for digital communication. It provides digital information at very low cost iButtonTM and simple structure. It can be used in the system needed multi-point data collecting. This paper introduces iButtonTM and MicroLAN, and then gives the design of an instance of multi-point data collecting——automatic key management system.
