摘要智能电话远程遥控系统以AT89C51单片机为核心，通过电话实现对密码门锁的智能控制，使用户可以在远端拨打与本系统连接的电话，实现智能门锁开、关的远程控制。
它是将该系统的两根传输线并联在电话机的两端，并不影响用户的正常通信。当用户从异地拔打电话并且振铃次数达到7次时，装置模拟电话摘机，语音提示输入操作码，CPU根据不同的操作码，执行相应的程序，完成开锁、修改密码、新增用户等操作。如果密码错误，经语音说明后，不执行任何操作，自动挂机退出。本系统中设置远程开锁、修改密码、设置新用户共三种功能，用户可根据初始用户信息自行设置账户信息，不定期更换密码，且操作简单，易于执行。初始用户信息唯一，不可更改，除用户本人外人无法获知。为了进一步保证该锁的使用安全性，系统中设置有报警系统，一旦检测到系统异常则发出警报。此外，该密码锁的表面光洁，无任何锁眼或按键，不法分子无法在门外实施撬锁，这使得用户的财产安全得到进一步保障。总的来说，它既能保障我们的人身财产安全，又可以方便我们的生活，且操作简单快捷，实用性很高，非常具有现实意义。34817

The design of remote control door lock with smart phone
[Abstract] Intelligent telephone remote control system of AT89C51 single-chip microcomputer as the core, through the telephone to realize the intelligent password lock control, users can in the remote dialing and the system is connected to the phone, to achieve intelligent door lock opening and closing of the remote control.
It is the two transmission line of the system in parallel at both ends of the phone, does not affect the user's normal communications. When the user is pulled from the remote call and the number of rings up to 7 times, the device simulation off hook telephone, voice prompt operation input code, CPU according to different operation code, executive corresponding program, completion of the lock, modify passwords, add users etc. operation. If the password is wrong, the speech that, without performing any operation, automatic hang out. This system set remote lock, modify passwords, setting up new users a total of three kinds of function, users can according to the initial user information to set their own account information, don't change regularly password, and the operation is simple, easy to implement. The only initial user information, can not be changed, except for the user I can not learn from the outsider. In order to further ensure the use of the lock, the system is set up alarm system, once detected the system is abnormal alarm. In addition, the password lock, the surface is bright and clean, without any lock or key, the criminals can not be outside the implementation of lock, which makes the property safety of users has been further guaranteed. In general, it can not only protect our personal property security, but also to facilitate our life, and the operation is simple and fast, practical is very high, very practical significance.
