为适应现今社会对于电话报警器的需求，保障机关家庭的财产安全。依据电话报警器的技术要求，研究制作电话报警器的自动拨号功能模块以实现电话报警器的自动报警功能。该模块主要分为两个部分：模拟摘挂机模块和DTMF收发模块。
DTMF收发模块以采用MT8880作为DTMF信号的收发器件，配合其他的外围辅助电路，接收识别电话信号音，接收发送DTMF信号，以实现电话的自动报警功能。
模拟摘挂机模块是通过硬件电路由单片机控制电路的连通与断开，以实现电话线与报警器电路的连接。
此外还包括振流检测模块和信号音检测模块。
本文主要介绍电话报警器的自动拨号功能模块的软、硬件设计的关键技术

In order to meet present-day society for a telephone device demand, the security organs of the family property. Telephone Alarm basis of technical requirements. Making a telephone study of automatic dialing function modules to achieve a telephone for automatic alarm function. The module consists of two parts : Abstract Simulation Interface module and DTMF transceiver module. DTMF transceiver module to adopt the MT8880 as DTMF signal transceiver device, coordinate with other external auxiliary circuit, receiving identification of the sound signal, the receiving Send DTMF signals telephone to the automatic alarm function. Abstract Simulation Interface module is hardware controlled by the MCU circuit connectivity with disconnected, to achieve the telephone line, and the alarm circuit connection. It also includes vibration detection module flow noise and signal detection module. This paper describes a telephone for automatic dialing module of the software and hardware design of key tech
