文档介绍：摘要
本文设计了一种光电式报警器,该报警器通过使用红外线发射二极管和红外线接收二极管等感光器件组成的光电转换电路,可以探测出光线是否被遮挡的信息,并通过把光信号转换成电信号来把这种信息传递至声光报警电路,以实现报警器报警的功能。其中传感器是指能感受规定的被测量并按一定规律转换成可用输出信号的器件或装置。通常由敏感元件和转换元件组成。光电式传感器是将光通量转化为电量的一种传感器,光电报警器是光电二极管和报警器的灵活结合,它可以运用到各种生产线上,如博物馆里的防盗系统,并提示物品被盗地点,安全性能高,节约了人力资源,并且不易出错;还能运用到其它人力不能监测的环境。显而易见,光电报警器的运用能延伸到社会的各个行业。

ABSTRACT
This paper designed a photoelectric alarms, the alarm by using infrared emitting diode and infrared receiving posed of ponents such as photoelectric conversion circuit, can detect the light is obscured information, and through the converts light signals into electrical signals to pass this information to the sound and light alarm circuit, in order to realize the function of the alarm. One sensor can sense refers to the rules be measured and to convert the available output signal according to certain rule of device or devices. Usually consists of ponents and ponents. Photoelectric sensor is power flux can be converted to a sensor, photoelectric detector is a bination of photoelectric diode and alarm, it can be applied to all kinds of production line, such as the museum of anti-theft system, and presented items stolen, safety performance is high, save human resources, and less error-prone; Can also apply to other human can't monitor the environment. It is obvious that the use of photoelectric detector can extend to society of each industry
Keywords :Photoelectric conversion ;Sound and light alarm circuit ;Photoelectric detector ;
第1章绪论
设计目的及意义
近年来,随着改革开放的深入发展,。各种高档家电产品和贵重物品为许多家庭所拥有。然而一些不法分子也是越来越多。。因此,。价格高昂,一般人们难以接受。如果再设计和生产一种价廉、性能灵敏可靠的防盗报警器,必将在防盗和保证财产安全方面发挥更加有效的作用。由于声控报警器体积小,灵敏度高具有很强的隐蔽性和保密性,因此在防盗、警戒等安保装置中得到了广泛的应用。声控报警器大多数采用国外的先进技术,其功能也非常先进。其中包括脚步触发报警器,汽车报警器,声控语音报时钟,“声控灯”等符合现在人们提倡的节能意识的产品更是受到现代人的青睐。此外,其价格低廉、技术性能稳定等特点也受到广大用户和专业人士的欢迎。
发展前景及现状
随着社会上各行各业的蓬勃发展,报警器已经在人们的日常生活中得到了广泛的应用,如汽车、摩托车报警器,仓库大门,以及各行业安全
