一种便携式远离提示系统的设计与实现

Design and Implementation of a Portable Far-From-Hint System

针对传统远离提示系统所需元件数量多、投入资金昂贵、功能较单一和灵活性较差等弱点,分析、研究了单片机和无线信号发射与接收技术,实现远距离报警的功能。远离提示系统由一个小型无线信号发射器和一个无线信号接收报警器组成。人们应用时,只需打开开关,将发射器置于贵重物品及孩子身上,接收报警器放置在物品主人或者家长身上即可。

Aiming at the weaknesses of traditional remote alarm system,such as large number of components,expensive investment,single function and poor flexibility,this paper analyzed and studied the technology of single-chip computer and wireless signal transmitting and receiving to realize the function of long-distance alarm.The remote alarm system consists of a small wireless signal transmitter and a wireless signal receiving alarm.When people use it,they only need to turn on the switch,place the transmitter on valuables and children,and put the receiving alarm on the owner or parents.
