摘　　要：为了进一步减少现有电子密码锁系统的规模,提高其性能的灵活性,设计了一种新型的语音电子密码锁。它具有智能语音提示、开锁、超次锁定、自动报警、管理员解锁、修改用户密码等功能,用FPGA(现场可编程门阵列)芯片和语音芯片ISD2560实现,体积小、电路简单。实际实验及仿真结果表明该设计功耗低、安全可靠,维护和升级方便,具有广阔的应用前景。In order to reduce the scale of modern electronic password lock system and enhance the flexibility of its capability, this paper introduces the design of a novel electronic speech password lock. Its functions are as follow： speech indication, lock open, lock over 3 times, auto-alarm, administrator unlock, password modification and so on. The design is implemented by a FPGA chip and a speech chip ISD2560, volume small and circuit simple. The practices and simulation results show this design is low power consumption, safety and convenient updating, has wide application foreground.
