摘 要
在当今社会，犯罪率逐年增长，威胁着人民的生命安全和财产安全。面对这种社会状态，提高人民的法律意识和素质是必须的。但是同时也要提高犯罪事件的预防手段。目前国内有许多种报警系统，每种报警系统都具有自己的特点，但是每种报警系统均存在不足，使不法分子可以轻松利用其缺点进行犯罪。本课题设计一种多传感方法的自动报警系统，使各种传感方法互补，将某种传感方法的缺点和不足得到弥补，达到真正的达到真正的全方位报警，并合理布置传感器，使系统达到最佳监控效果，并在检测过程中报警测量精度防止误报警。
本次设计的多检测法银行自动报警系统是通过多种传感方法同时监测，并且能够自动报警的智能报警系统。该系统主要采取的传感方法有：红外线传感、震动传感、压力传感、超声波和声音传感等。本次设计主要对银行分为几方面进行设计。银行主要监测的位置有门口、窗户和金库。对于窗户主要防止的是对犯罪分子对窗户进行破坏，主要的测量对象为震动和压力，相应的采用震动和压力传感器对其进行监测。门口的检测主要是对门的破坏以及对有无人进入门口的检测。所以在门口也要采用震动和压力传感器，同时还要采用红外线传感器对门口的监测。对于整个银行内部要采用超声波传感器，银行内部的总体情况进行监测。对于最重要的金库会采用所有的传感方式进行监测，同时还要采取高压电防护系统。同时为了防止在休息时间发生内盗，给系统增加设定时间的功能。通过系统的键盘设定时间区域。使任何人在特定时间内都不能开启金库。当发生偷盗时，系统会以声光报警的形式提醒在银行内的人员。同时，系统通过公共电话网拨打110报警。以上就是该系统所实现的功能。
本次设计的银行自动报警系统，弥补了当今市场上的报警系统检测手段单一的缺点。在发生偷盗事件时，能够迅速的发出报警，并且拨打110自动报警。该系统采用的多种传感方法，扩大了监测的范围。减少了银行内的盲点。并且，本次的设计成本相对较低，准确性高。将会成为银行保安系统中重要的组成部分。

Abstract
In today's society, the crime rate is growing year after year. A threat to people's lives and property safety and security.Faced with this social state, raising people's awareness of the law and the quality is necessary. But at the same time, It also enhance crime prevention methods. At present, there are many kinds of domestic alarm systems, but often there are many shortcomings with them,so that criminals can easily use their weaknesses to crime. This topics will design a method of automatic multi-sensor alarm system to make all the methods help each other. And cover the shortcomings of other sensing method.Go up to a real alarm which all around it. Rational arrangement of sensors to make the system go up to a best monitoring results,and prevent the mistakes in the testing process.
The design of multi-bank automatic detection alarm system is monitoring through many kinds of sensing methods.It an intelligent automatic alarm system. The main sensing method of this design are like these: Infrared sensor, Vibration sensor.
 Sensing the pressure, Ultrasonic sensing and Sound sensor, etc. This design devide the bank into several respects to design. The main  places of monitoring are the door, windows and treasury.The importance to the window is preventing the distroies from the criminals, the main measuring objects are Vibration, and Pressure,to monitor them with the Vibration, and Pressure sensors.The detection to the door is responsible for someone come in or someone go out of the door.So the Vibration, and pressure sensors,are also important at the door,at the same time ,the Infrared sensors,is indispensable.We must use Ultrasonic sensors in anywhere of the bank,to monitoring the overall situation in the bank.To the most important treasury it will use all the sensing methods to monitor.It will use the High-voltage protection system at the same time.In order to prevent the bootlegging at the rest time,it was added the function of setting time which was made through the keys.All the people can’t open the treasury in given time. When the theft happend,the system will remind the people who is working in the bank by the way of Sound and Light alarm.At the same time ,the system will call the 110 by the Public telephone network.
These are the functions achieved by the system,the  Bank automatic alarm system of this design covered the single shortcoming of Alarm Detection System in the market today.It can alarm quickly when the theft incident happened and call the 110 by itself. It has expanded the scope of monitoring and reduced the bank's blind spots by using many kinds of sensing methods. And the costs of this design is very low. The accuracy is very high. It will be an important part of Banking security system.
