摘要
本文介绍了,多功能防盗报警器的制作过程、工作原理,以及多功能防盗报警器在生活中的应用。
目前市面上装备主要有压力触发式防盗报警器、开关电子防盗报警器和压力遮光触发式防盗报警器等各种报警器,但这几种比较常见的报警器都存在一些缺点:压力触发式防盗报警器由于压力板式安装在垫子内,当主机停止工作,主人在家走动时,都很容易误报,其可靠性低。开关式电子防盗报警器一般只有一个定点,有效范围小,而且各种开关也易坏,误报率高,不可靠。遮光式触发防盗报警器在受到太阳光照射就会引起误报,同时如果由于风吹窗帘的摆动等遮住了光也会引起误报,所以这种报警器的可靠性也不高。再者,就闭路监控电路防盗系统而言:它的安装线路复杂,而且技术要求比较高,价格也比较昂贵,不利于广泛利用。
在认真的考虑以上报警器的不足之后,ZX2039型多功能防盗报警器利用NE555电路和GL9561电路为核心。在控制上采用了水银开关,将振动转换为电路的连接,它的制作简单、成本低,安装比较方便,而且防盗性能比较稳定,抗干扰能力强、灵敏度高、安全可靠。这种防盗器安装隐蔽,不易被盗贼发现。

Abstract
This article describes, burglar alarm multifunction production process, working principle, as well as multi-functional burglar alarm in the life of the application.
Currently on the market are equipped with pressure-triggered burglar alarm, electronic anti-theft alarm switch and pressure blackout triggered burglar alarm and other alarm, but several of the mon alarm, there are some drawbacks: pressure-triggered alarm alarm due to the pressure plate mounted on the mat, when the host stops working, the owner when walking home, very easy to false positives, its reliability is low. Electronic anti-theft alarm switch generally only one point, the effective range is small, and a variety of switches also perishable, high false alarm rate, unreliable. Shading style burglar alarm triggered by sunlight in will cause false positives, and if the wind blows the curtains covering the light swing, etc. can also cause false positives, so this alarm reliability is not high. Furthermore, the anti-theft systems, closed-circuit monitoring circuit: plexity of its installation and technical requirements are relatively high, the price is more expensive, is not conducive to extensive use.
In a serious lack of consideration of the above alarms after, ZX2039 multifunctional anti-theft alarm circuit using the NE555 circu
