这里介绍的是家庭安全监控系统。该系统主要通过人体红外热释传感器、门磁位移等传感器采集报警信息,通过无线传输给由单片机AT89C55WD控制的电话双音频编解码芯片MT8888和语音芯片ISD1420、ISD1110实现电话报警。本系统实现了自动电话报警(紧急求救)、警笛现场提示、在线显示事发地点和用户资料以及常用电话等功能。该系统适用于家庭、居民小区、工厂等易于集中管理地方的安全防护工作。并重点介绍了系统框图、程序设计图、主要原理等。
Here is a home security monitoring system. The system mainly through the human body infrared pyro sensors, magnetic sensors and other sensors to collect alarm information collected by the wireless transmission to the phone AT89C55WD controlled by the phone dual-audio codec chip MT8888 and voice chip ISD1420, ISD1110 telephone alarm. This system has realized the automatic telephone alarm (emergency), the siren scene prompt, the online display place and the user information as well as the common telephone and so on the function. The system is suitable for home, residential areas, factories and other centralized management of local security work. And introduced system block diagram, program design, main principle and so on.
