【内容概述】

随着经济的发展,人们的生活质量日益提高,人们对生活就有了更高的要求,各个家庭、企事业单位以及大型的公共场所都装有品种繁多的电器用具。但是,由于私家车的数量的日益增多,盲人群体生活的不便捷,以及许多电器和生活必需品都存在多多少少的安全隐患,这些都对社会安全构成了威胁。例如,在家庭中,由于人们的疏忽忘记了关闭煤气,这样的事情很多,轻则伤身,重则丧命,从而带来人间的悲剧。当一些企事业单位或商场发生火灾的时候,又没有人注意到,时间长了就会引起严重的后果。私家车增多,许多驾驶员对复杂的道路信息或路标不熟悉,很有可能会引发一些交通事故,而目前道路信息的提示主要依靠公路边的路牌,若遇到阴雨或大雾天气,这些路牌的能见度就会大大降低,所以可能使驾驶员错过一些重要的道路信息,带来不必要的麻烦。盲人群体由于视觉上的障碍也时有危险的事件发生。本文将单片机技术和蓝牙无线通信技术相结合,设计了一个基于蓝牙技术的安全提示系统 ,应用非常广泛,该系统由两部分组成,一部分是安全提示点,用来给携带了另一个系统的人发送危险提示信号;另一部分是接收安全提示点发来的信号且选择事先存好的语音信息,然后用语音的形式播放出来。本文首先介绍了该系统的背景和研究意义,其次简单介绍与其相关的技术,再次提出本系统的总体设计思想,最后分模块来介绍本系统的设计和实现过程。本文中实现的系统模型为道路信息提示提供了一套可行的解决方案,随着系统功能的不断完善和扩展,基于蓝牙技术的安全提示系统必将得到广泛的应用和肯定。

SAFETY REMINDING  SYSTEM  BASED ON BLUETOOTH
Abstract
With the development of the economy and the improvement of people’s living standard ,people’s requirement of life have increased ,so families, enterprises, institutions and public places are equipped with a wide variety of electrical appliance. While the number of private cars is increasing, the inconvenience of the blind, what’s more ,the appliances and necessities are unsafe to some degree, the state of affairs above have threaten the safety of our society. In families, people forget closing of the gas because of negligence, such situations are very common .Lightly, they are pernicious to health ,seriously, they will kill people, thus bring tragedy to people. When some institutions or stores catch fire, and no one notice that, in the long run it will cause serious consequences. The numbers of private cars has increased , many drivers are not familiar with the complexity of the road information or signs , they are likely to cause some traffic accidents, while the tip relies mainly on the information on the highway sides of the signpost currently, if it is rainy or foggy ,these signs will be greatly reduced visibility, which could make the drivers miss some important information and cause unnecessary trouble. The dangers are often happen to the blind because of visually impaired.
This paper combine the single chip microcomputer with bluetooth wireless communication technology, and design a safety reminding system based on bluetooth, technology ,which is widely applied, this system is consists of two parts, one is safety reminding used to give hints of another system which carries the risk, The other part is receiving safety reminding and choose the voice information which has been stored in advance , then it will broadcast it .
Firstly, this paper the background and the studying significance of the system, secondly, it gives a brief introduction and some technology involved, thirdly the paper puts forward the design concept of the system, finally it introduce the process of the design and realize of the system in module.
The model of the system realized in the paper support a serious of feasible program for the information reminding of roads. With the consummatement and expanding of the system’s function . The safety reminding system based on buetooth technology will be widely used and obtain people’s approval .
