摘　　要：针对实验室门禁采用传统的机械锁、大盘钥匙开锁带来的不便,项目组设计了一款基于51单片机STC89C52RC的指纹电子密码锁,该密码锁可以实现指纹和红外遥控两种方式开锁,密码错误3次后还会报警,具有防多次试探键入、成本低等特点。考虑到需要24 h待机,对硬件和软件进行了多次改动,使得功耗降低为150~350 m A,达到了较为理想的效果,可以应用于实验室的实际管理中。In view of the inconvenience caused by the traditional mechanical lock and the key unlocking of the laboratory,the project team designed a fingerprint electronic lock based on 51 SCM STC89C52RC.The password lock can realize the two ways of fingerprint and infrared remote control to unlock,and the system will alarm after three times password error,and has the characteristics of multiple test entry and low cost.Considering the need of 24 hours standby,the hardware and software have been changed many times,so that the power consumption is reduced to 150-350 mA.The system achieves the desired effect and can be applied to the actual management of the laboratory.
