摘　　要：介绍了P87LPC764单片机性能特点及以该单片机为核心的智能化门禁系统的设计与实现。描述了系统主控单元的选择及系统的整体设计,分析了系统所采用滚动编码的加密原理并对滚动编码与固定编码的安全性作了比较。该门禁系统已投入生产,运行可靠,取得了很好的实效。This paper introduces the performance characteristics of the MCU P87LPC764 as well as the design and realization of an intelligent gating system with this MCU as its heart. Also, this paper describes the main control unit and the whole design of the system, and analyzes the encryption principle of the code hopping encoder adopted by this system. At the meantime , the security performances of code hopping encoder and code fixed encoder are compared. This kind of door entry control is becoming popular, since it runs reliably and has good effect .
