摘要
为了使单个控制系统能够处理多路韦根信号,提出了采用单片机主从结构和并行扫描的新技术。从硬件和软件两个方面,介绍了AT89C2051单片机对多路韦根信号的采集、数据处理及通讯的设计及实现方法,并在软件执行效率方面作了重点分析。
In order to acquire and process multi-channel Wiegand signal, a new technology of adopting Master/Slave structure and parallel scanning of SCM is presented. In hardware and software aspects, the design and implementation of Wiegand signal acquiring , datas processing and communication based on AT89C2051 SCM are described, and efficiency of software execution is stressed.
