蓝牙4。0技术智能看护系统设计摘要近些年来，通信技术以及物联网技术的迅猛发展，各类型主流开发板的存储和计算运算能力也随之增强，其性能足以满足替代日常控制及智能化开发的方方面面，除了继续向大型化、高速化方向发展的同时，向着微型化、智能化方向发展的PDA等嵌入式设备也开始大量登上历史的舞台。该方向应用目的诣在解决广大群众在生活中的各类需求，并再效率、智能化、人性化的实现提供了技术上的无限可能。这些技术的竞争直接催生了物联网（IOT）成为研究热点。物联网在通信服务方面能提供的服务包括了短距离和长距离两种。并且，随着无线传输技术的应用和发展，充彻着物联网的环境已经开始大量存在于本系统生活的周边。83355

本研究针对智能看护的市场需求，结合目前广大人群眼睛视力出现的不断突出的各类问题，研究和实现了一款简易可用的智能眼镜辅助设备，以提供实时、可靠的用眼卫生提示和警告帮助，帮助使用者形成良好的用眼习惯。功能如下：

（1）定位查找功能；可以在手机端通过APP连接眼镜端的蓝牙芯片控制蜂鸣器报警定位；

（2）用眼疲劳提示；自动计算看书学习的时间，到达一定时间后休息提醒，防止眼睛疲劳；

（3）自动光测警告；自动测试光强是否能达到学习看书条件，如果太暗或太强的情况自动报警。

本文具体介绍了蓝牙4。0技术的特点与应用范围，总结出在日常生活的智能看护领域中蓝牙4。0 具有不可替代的优越性。目前，研究并设计出的系统总体方案，包含了探测模块、处理模块和报警模块，各类传感器对周遭环境进行采样探测，经过a/d转化后变为数字信号，nRF51xx系列开发板的Cortex M0为信息处理模块，蜂鸣器与红色LED等实现对周遭数据的处理和报警。将本产品裁剪后通过物理模型设计，集成到眼镜上后，可有效帮助使用者重新养成良好的用眼习惯，减少使用眼镜的诸多不方便之处，后期可申请相关专利，具有一定的市场价值。

Abstract With the rapid development of communication technology and network technology in recent years, various of mainstream development board of the storage and computation ability also increases。 Its performance could meet the daily control and intelligent development of alternative aspects。 In addition to continuing to large-scale, high speed direction, miniaturization, intelligent direction is the other mainstream and the embedded devices like PDAs are also boarding the stage of history。 The meaning of these application  in addressing the various needs of the broad masses of the people in life, and more efficiency, intelligent, humane provides technical possibilities。 The competition of these technologies directly gave birth to a totally new technology called the Internet of things (IOT) , which has became a research hotpot immediately。 In terms of communication services, IOT can provide series of services mainly including used in a short distance and in a long distance。 Moreover, with the application and development of wireless transmission technology, the environment of the Internet of thing is appearing an increasing number in our life。

The system aimed at the demand intelligent care market , considering the different kinds of  serious eye sight problems due to bad habits and careless, implement a simple smart glasses available auxiliary equipment to provide real-time, reliable eye health tips and warnings, helping users to form good habits with the eyes。 Functions are as follows:

(1)Search positioning: the alarm can locate the phone thought connecting  glasses Bluetooth  for controlling the chip buzzer;
