Yu Feng · Journal of Qingdao University of Science and Technology · 2007
An intelligence entrance guard system scheme based on radio frequency identification(RFID) technology is designed.The system takes W77E58 as core controller to identify the passwords and card information.The network is composed of many multipoint control unit(MCU) parts connecting with PC through 485 Bus.The PC not only manages the information of cards and users by files and databases,but also does real-time watch and control of the in-out situation of doors through 485 bus.This system has been put into practice as an experiment,and now it runs well and stably.
