智能電話遠程遙控系統以AT89C51單片機為核心,通過電話實現對密碼門鎖的智能控制,使用戶可以在遠端撥打與本系統連接的電話,實現智能門鎖開、關的遠程控制

摘要智能電話遠程遙控系統以AT89C51單片機為核心,通過電話實現對密碼門鎖的智能控制,使用戶可以在遠端撥打與本系統連接的電話,實現智能門鎖開、關的遠程控制。
它是將該系統的兩根傳輸線并聯在電話機的兩端,并不影響用戶的正常通信。當用戶從異地拔打電話并且振鈴次數達到7次時,裝置模擬電話摘機,語音提示輸入操作碼,CPU根據不同的操作碼,執行相應的程序,完成開鎖、修改密碼、新增用戶等操作。如果密碼錯誤,經語音說明后,不執行任何操作,自動掛機退出。本系統中設置遠程開鎖、修改密碼、設置新用戶共三種功能,用戶可根據初始用戶信息自行設置賬戶信息,不定期更換密碼,且操作簡單,易于執行。初始用戶信息唯一,不可更改,除用戶本人外人無法獲知。為了進一步保證該鎖的使用安全性,系統中設置有報警系統,一旦檢測到系統異常則發出警報。此外,該密碼鎖的表面光潔,無任何鎖眼或按鍵,不法分子無法在門外實施撬鎖,這使得用戶的財產安全得到進一步保障。總的來說,它既能保障我們的人身財產安全,又可以方便我們的生活,且操作簡單快捷,實用性很高,非常具有現實意義。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.
