一、项目介绍 有许多的爱好运动的人群,因为天气,地形地势的许多原因,需要把自己的位置信息记录并且保存下来,以防出现不可预知的危险。许多人选择采用手持设备价格比较高,好比SkyCaddie的SG5价格在2800左右,i-gotU的 GT-800价格在1700左右,功能却是几乎一样的。基于此,我想到制作一个保护系统,这个系统可以帮助他们解决以上问题,这个保护系统有两个模块,其中之一是便携式终端,戴在人的身上,要有低功耗,良好的供电,且具有GPS定位功能,向固定模块发送数据的功能。另一个固定模块是由伽利略开发板构成的智能化定位救助系统,有与用户设定的协议端通信功能。使用的其他参数由伽利略开发板上面移植的系统开发出的程序来设定,如果便携式终端在一段时间响应不符合固定模块用户已经设计好的运动数据,就默认为用户发生异常,然后定位用户GPS并且发送到设定好的账户。 基本功能: Ø 可以获得用户基本位置 Ø 可以获得用户基本位置 Ø 可以把用户的位置以短信发给普通朋友 Ø 共享位置信息 开发者个人情况: 做过430开发,接触过Arduino系列,半年左右嵌入式开发 二、英特尔Galileo开发板设计应用 伽利略开发板模块作为数据查看,处理单元,利用GPS测量用户当前位置并加以保存处理,处理好的数据通过短信收发模块传送到设定的手机,加以提醒。 伽利略开发板在项目里面起到了什么作用: 1. GPS数据处理 2. SIM900A短信发送主机 3. 显示控制中心 主要元器件: ● AC220转DC12电源模块、DC5V电源; ● 伽利略开发板; ● GPS 数据采集模块; ● Sim900A通讯模块; ● 数据显示模块; 开发环境: Arduino IDE 1.5.3 三、项目点评 开发难度:难度较难,对硬件电路的稳定性、体积、续航要求,数据的处理精度、传输实时性都有较高的要求; 创新性:将GPSR数据传输和GPS定位相结合,稳定性高; 可发展性:在保护弱势群体的人生安全有广泛应用,尊老爱幼是中华名族的传统美德,给老人和子女创造一个健康、安全、幸福的生活环境变得非常有意义; 实用性:实用性很强,不仅能对像老人、孩子这样的弱势群体进行实时的位置查询,在其他方面的应用也很广泛,犯罪嫌疑人跟踪,汽车定位追踪等; 四、项目图片
