摘　　要：介绍一种基于在系统可编程(ISP)技术和复杂可编程逻辑器件(CPLD)的新型电子密码锁的设计方法,阐述了其工作原理和软硬件设计。在硬件上,用Lattice公司的ISP大规模集成芯片对其外围电路进行集成,用1片CPLD实现了几十片分离元件才能实现的功能,几乎将整个系统下载于同一芯片中,实现了所谓的片上系统,从而大大简化了系统结构,增强了系统的可靠性和性价比。该密码锁特别适用于宾馆、办公大楼、仓库等人员经常变动的场所。An electronic coded lock based on in system programmable (ISP) technology and complex programmable logic device(CPLD)is introduced in this paper. The operation principle and design of hardware and software of electronic coded lock are introduced in detail. It adopts the in system programmable large scale integrated chip of lattice corporation to integrate the periphery circuits and uses a CPLD to implement the function of tens of separated chips. Thus it reduces the system structure and enhances the reliability and cost performance of the system. The electronic coded lock is suitable for hotel, office building, warehouse and so on.
