The Design of Remote Intelligent Anti-theft Alarm System
Abstract: With the improvement of living standards, the traditional device is increasingly unable to meet daily needs, a reasonable solution is put forward in the system, which is formed by infrared technology, SCM principles and automatic alarm anti-theft technology , the system is scientific, economic and efficient. Modular thinking is used in the system and each section is designed by modular, which make the system more convenient to apply to, stronger to avoid interference, more sensible and more reliable. The intrusion signal is first collected by the system piezoelectric sensor and vibration displacement sensor, and the transmitted to the host AT89C51. After that, the signal is sent by the host to the buzzer circuit, a voice module and a DTMF module, DTMF module and the alarm signal is sent to the user’s phone through DTMF module. Microcontroller-based alarm system has the advantages of small size, low price, easy to operate and highly integration, which has a broad application prospects.

远程智能防盗报警系统设计
引言
随着居民生活水平的提高，传统的防盗越来越不能满足人们日常防范的要求，因此人们迫切需要一种智能型的多功能安防报警系统，使其能可靠的进行日常安全防范工作，及时发现各种警情并做出相应处理，保障居民生命和财产的安全。对市场上出现的各种报警装置进行了研究之后发现, 目前市场上的防盗器大致可分为报警式和微机监控式两种。前者价格比较便宜，结构简单，但是只有单纯的报警功能，其应用受到了限制；而微机监控式防盗器装置先进，在很多重要场合得到了广泛应用，但是成本较高。
