摘要:近年来,防盗系统越来越受到人们的重视。但是市场上的报警器,价格昂贵,通常用于一些大公司财政机构,一般人们难以接受。如果能设计和生产出一种价格低廉、性能灵敏可靠、安装在房门上的防盗报警器,将会在防盗和保证财产安全方面发挥更加有效的作用。本文中的门控声光报警器就是基于以上因素而设计的。 本设计采用NE555集成电路、CK9561集成电路和LM317集成稳压器等,实现了将预置封锁、延时、声光报警、报警记忆和灯光控制等功能电路集于一身,加上供电电源设计为一体的报警器电路。这种报警器安装到门上后,既可作开门照明灯控制器使用,又可作防盗报警器使用。 关键词:NE555;报警;记忆;防盗;门控
Abstract:In recent years, anti-theft system, more and more attention has been paid. Alarm on the market are expensive, usually used in some large companies financial institutions, in general it is difficult to accept.If you can design and produce an inexpensive, sensitive and reliable performance, burglar alarm installation in the door, will play in the anti-theft and to ensure property security and a more effective role. Gated in this article sound and light alarm is designed based on the above factors.This design uses a NE555 IC, CK9561 and set IC LM317 as the regulator, etc., to achieve a preset blockade, delay, audible and visual alarm, alarm memory and lighting control circuit rolled into one, plus the power supply design as one of the alarm circuit. This alarm installed on the door, both for the door lighting controller, but also for the burglar alarm. Key words: NE555; alarm; memory; theft; gated
随着人们的生活水平不断的提高,各种高档家电产品和贵重物品为许多家庭所拥有,虽然市面上出现各种防盗锁、防盗门等防盗功能很好的防盗产品,大大提高了家庭成员和财产的安全性,但一套大型的防盗系统价格都比较高,这相对于农村农民收入来说,是无法购买的。因此简易的报警器得到了人们的青睐,同时随着防盗产品不断出现,功能也不断完善,不法分子开锁的技能也就层出不穷,手法也越来越高明,一些如万能钥匙等的东西也就随之出现,这样一来只要门一被打开家里的东西就将被偷,如果有某种报警器安装在门上,当门被打开后,延时几秒钟,如果不及时关掉暗藏报警器电源开关,将会发出报警,并记忆报警,将会在一定程度上起到防盗的作用。而本文设计的门控防盗报警器就是这种用于安装于门上的报警器,除了有声光报警功能外,还有记忆报警和夜间开门控制照明灯亮的功能,可作报警器用外,还可作夜间开门照明灯控制器用。是一种较好的简易两用防盗报警器,符合广大老百姓的需求。
