基于DTMF技术的智能住宅安防系统

文章阐述了利用双音多频(DTMF)技术,在现有电话网中实现智能住宅的远程报警和控制的具体实现方法,在本系统中采用了适用于我国来电显示(FSK制式)的来电显示解调器—FX602,通过它与单片机的配合使用,以先判断来电号码是否为有控制权限的号码再决定是否使用自动摘机的方式,解决了以往电话报警和控制系统中每当有电话打入系统就自动摘机的问题。此方法可以适用于智能住宅及普通住宅的智能化改造。实际应用表明该方法稳定可靠,成本低,具有重要的应用和推广价值。

Smart Home Security and Defense System Based on DTMF Transmission

In this paper an idiographic system of realizing remote warning and remote control of Smart Home ,making use of DTMF technique in existing network of telephone. The FX602 is adopted in the system, it is suitable for using the telephone number show ( FSK service pattern) in our country. through using the system and the monolithic integrated circuit together ,it will decide the way of automatically picking the telephone by judging whether the number have the control right, it solves the problem of the system automatically picking the telephone when is called. The kind of system can be used in many smart home system and normal home smart update. Practical application indicated this system is stable and doable and it is of important values in generalization and application.
