1、室内防盗报警器电路设计室内防盗报警器电路设计前言 随着科学技术的迅速发展,数字电子技术的概念和分析方法已经渗透并应用许多种不同的领域中。但,随着科学技术的发展,盗窃团伙的犯案手法也变得层出不穷。他们不是一个落后的团伙,他们也得利用高科技犯案。因而侦破盗窃案,成了公安机关的一大难题。防止盗窃犯罪的发生,不仅是公安机关的责任,普通公民也应该保管看护好自己的财物,以免盗贼有机可乘。特别是那些无人看管的财物,更是为贼人提供了“优异”的作案环境。因而在家中安装防盗报警系统,是预防被盗的有效方法。 当家中无人的时候,家中的贵重物品便成了主心中的“牵挂”。为了更加安心地出门,在家中安装防盗报警器是最直接的方

2、法。出门前,启动报警器,当有人非法进入内时,触动了早已装置的报警器。报警器,便会制造声响,以吓走盗贼或引起邻居的注意,做到防盗的目的。 但同样令主人头痛的就是,市面上有着各种各样的报警器,选择,是一件难事情,担心这样那样的事情。还有就是它们的性价问题 通过自行动手,翻阅资料,本人设计了任务要求的具有“记忆”性的红外线家庭防盗声光报警器。在思考和设计过程中,我由浅入深,从认识器件开始到自行改装和设计电路,加深了对所学知识的认识和了解,增长了见识,提高了能力, the provisions of Hunan province safety production supervision and ma

12、状态,因为启动电路已经把继电器锁上,“记忆”，,不按复位开关,即2电器常开开关不会打开。这样贼人就无法停止报警器“报警”,除非他破坏了电路，。此电路对阻吓贼人较强大的作用,防盗实用较大,制作也不太复杂,操作容易,材料也较容易买到,具有一定的商用价值 ,2，设计电路的主要性能指标 A,此电路由6V的直流电源供电。电路也可用612V的直流电源,只需要更换部分元器件即可。 B,电路采用稳定性高的555集成电路组成。IC1是利用输出脚电平的高低来控制继电器常开开关的开与合。IC2与IC3构多谐振荡器,负责控制闪光灯和喇叭。 C,该电路耗电低,在没有触动报警的情况下,启动电路部分耗电流仅20mA左右;警

13、报电路部分根本不耗电。报警时,启动电路电流达数十mA，报警电路仅为20mA左右。 D,红外光接收管反应敏捷,受到红外光照射时管子保持截止的状态，当红外光线被阻截时,管子立即导通,启动继电器工作,即是报警器开始报警。 E,“红外线发射管”和“红外线接收管”两端可以并联多组“红外线发射管”和“红外线接收管”,使其“探测”范围更广。 the provisions of Hunan province safety production supervision and management responsibilities (Hunan Zhengban made 2013 No. 4), resolu

23、警器工作时,被触动后,报警器的闪灯和喇叭不停工作,以阻吓贼人和引起别人注意。直到主人重新设置报警器为止。 由以上几点,最后决定用555集成电路对设想中的电路进行控制。 ,2，理解555集成电路的工作原理,以更好地设计电路。 ,3，设计构想中的电路 首先设计继电器的启动电路,利用单个555集成电路的输出端电平的高低以及其复位的作用来控制继电器的开与关。然后设计闪烁灯和喇叭的警报电路,利用两个555集成电路组成的多谐振荡器,对闪烁灯和喇叭发出的声音进行控制,以达到设计的要求。 考虑把“红外线发射管”和“红外线接收管”安装在哪个电路上,以达到最少的影响。最后画出简单的分部电路图,以便进行组合。 ,4

24、，根据画出的简图,利用EWB软件进行测试 先对启动电路进行测试，然后对警报电路进行测试，再把“红外线发射管”和“红外线接收管”分别接到电路上,测试其影响,并决定把“红外线发射管”和“红外线接收管”放在哪个电路上，最后把两个电路组合其来,并进行测试。 ,5，根据测试的结果得出设计好的电路图。 ,6，进一步理解报警电路。 the provisions of Hunan province safety production supervision and management responsibilities (Hunan Zhengban made 2013 No. 4), resolutely
