智能报警器的设计与制作
汽车防盗报警[摘  要]：随着我国的崛起，电子电器的飞速发展.人民的生活水平有了很大提高。各种自行车，电动自行车，摩托车，汽车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。这点就是看到了大部分人防盗意识还不够强，造成偷盗现象屡见不鲜。因此，越来越多的居民家庭对财产安全问题十分担忧。
振动报警器能这种电路主要由振动放大电路、单稳态触发器电路、报警电路组成，设计利用三极管放大后触发由NE555集成芯片构成的单稳态触发器,输出电压驱动报警器工作。

Design and production of intelligent alarm
Abstract：With China's rise, the rapid development of electronic appliances. People's living standard has been greatly improved. All kinds of bicycles, electric bicycle, motorcycle, car and valuables owned by many families. However, some unlawful elements are also more and more. That is why most people see the security awareness is not strong enough,
caused by the theft phenomenon it is often seen. Therefore, more and more households are very concerned about security issues on the property.
Vibration alarm can this circuit is mainly composed of a vibration amplifying circuit, biostable trigger circuit, alarm circuit, design of the triode amplified to trigger a biostable multivibrator is composed of a NE555 integrated chip, the output voltage driving.
