摘要
介绍了一种失常生物信号紧急自动拨号报警装置的硬件电路、软件编程和系统整体调试。该装置由单片机和其他外围电路构成,分为四个功能模块:模拟摘挂机、语音录放、信号音判别和DTMF双音多频拨号自动发送。实验证明,该装置的软、硬件设计能够通过功能调试,可以达到设计所要求的功能。
A new emergency automatic dialing alarm system for abnormal biological signals is introduced here, including hardware circuit ,software procedure and integrated debugging. The alarm system is composed of single chip microcomputer and other necessary peripheral circuits. There are four functional modules contained in the system, including simulated offhooking and hanging up,dialogue recording and playing, signal tone distinguiShing and DTMF signal sending. The hardware/ software design can reach function of the design by debugging.
