摘　　要：为了实现对家居环境安全状况实时的监控以及在发生警情时能自动拨号进行语音提示或发送报警短信,设计了一种基于GPRS和数字无线技术的嵌入式电话报警系统。该系统以SoC(在片系统)单片机C8501F020为控制与处理核心,并利用2.4 GHz数字无线传输技术连接传感器,接收传感器采集的信号,对周围环境进行监控。同时,该系统结合GPRS短信功能和固定电话网络,实现报警信息的可靠传递和远程控制。系统还设计了终端界面,可方便用户进行系统设置密码或预置报警电话号码,以及生成和查询系统报警日志。An embedded phone alarm system based on GPRS and digital wireless technology was designed to realize the real-time menitoring and automatic alarm. A SOC （system on chip） microctroller C8051F020 is used as controlling and processing core in the system. The 2.4 G digital wireless technology is used to connect sensors with control unit, transmit signals collected by sensors and monitor the surroundings. The system implements the reliable transmission and telecontrol of alarm information in combination with GPRS SMS function and telephone network. The computer terminal interface was also designed to make its users to easily set password and phone numbers or inquire about alarm log.
