基于单片机控制的双模式儿童防走失系统设计

Design of double-mode for prevention of children being lost based on the control of singlechip microcomputer

鉴于传统儿童防走失系统使用的局限性,介绍了一种基于单片机控制的、可以工作在无线信号与移动信号两种数据传输模式下的儿童防走失系统。分析并利用GPS全球定位系统,准确获取儿童所在位置的经纬度信息,通过某种数据传输方式将数据传输给父母端设备,处理数据并图形显示儿童与父母的具体或是相对位置。

Since the limitation of traditional prevention for children being lost system,the paper introduces a new system used to prevent the children＇ getting lost based on the control of singalchip microcomputer.The new system can convey data both under wireless signal and mobile signal.Getting the position information of children exactly by analyse and use the global position system, and send the data to the device used by their parents by some transmission mode,then it can deal with the data and show the exactly position or relative position.
