摘要
   该电子密码锁能充分利用了51系统单片机软、硬件资源，引入了智能化分析功能，提高了系统的可靠性和安全性，另外，电子密码锁若与串行通信结合在一起将会成为宾馆、工厂、学校等需要进行统一管理的建筑群不可缺的商品。
 机电一体化的电子密码锁，其功能大大超过弹子锁，且性能更稳定、更安全。其特点，首先保密性好，其次编码可变；其三误码输入保护；其四停电不掉码；其五多种密码开锁方式，使用方便，没有单人开锁、二三人多种开锁方式。由于自身的优势，电子密码锁会受到越来越多人们的欢迎，使用会越来越广泛，同时，也将会被社会所接受认可，并与弹子锁平分秋色。

abstract
     This electronic combination lock could use 51 system monolithic integrated circuit software and hardware resources fully, has introduced the intellectualized analysis function, enhanced system's reliability and the security, moreover, electronic combination lock, if with the serial communication unified will become the guesthouse, the factory, the school and so on to need together to carry on the commodity which the global administration the architectural complex could not lack. Integration of machinery's electronic combination lock, its function surpasses the spring lock greatly, and the performance is stabler, is safer. Its characteristic, the secrecy is first good, next the code variables; Its three error code input protection; Its four power cut code; Its five many kinds of password unblanking way, the easy to operate, does not have the single to unlock, 23 person of many kinds of unblanking ways. As a result of own superiority, the electronic combination lock will receive more and more people's welcome, the use will be getting more and more widespread, simultaneously, also will be accepted by the society the approval, and will share half and half with the spring lock.
