基于AT89C52单片机的智能呼救系统设计

从系统硬件设计和软件构成上,介绍一种以AT89C52单片机为核心,通过无线遥控方法实现对预设电话自动拨号报警的智能呼救系统。系统提供了患者在紧急情况下无法使用电话报警时的一种报警手段。由用户预设的多组电话号码作为语音报警对象,预录可长达20 s的语音信号来说明患者所处地点及病情,并通知患者家人。 <DL class=en id=eabs> <DT>Abstract: <DD>&nbsp;Thi

基于DSP的ATV-ATT中控系统设计

设计一种应用于某全地形ATV车载武器装置中的中控系统,该系统设计是以TMS320F2812型DSP为核心,采用模块化设计思想,对其硬件部分进行系统设计,能够完成对武器装置高低、回转方向的运动控制,实现静止或行进状态中对目标物的测距,自动瞄准以及按既定发射模式发射弹丸和各项安全性能检测等功能。通过编制相应的软件,对其进行系统调试,验证了该设计运行稳定。 <DL class=en id=eabs>
