摘 要
在當今社會，犯罪率逐年增長，威脅著人民的生命安全和財產安全。面對這種社會狀態，提高人民的法律意識和素質是必須的。但是同時也要提高犯罪事件的預防手段。目前國內有許多種報警系統，每種報警系統都具有自己的特點，但是每種報警系統均存在不足，使不法分子可以輕松利用其缺點進行犯罪。本課題設計一種多傳感方法的自動報警系統，使各種傳感方法互補，將某種傳感方法的缺點和不足得到彌補，達到真正的達到真正的全方位報警，并合理布置傳感器，使系統達到最佳監控效果，并在檢測過程中報警測量精度防止誤報警。
本次設計的多檢測法銀行自動報警系統是通過多種傳感方法同時監測，并且能夠自動報警的智能報警系統。該系統主要采取的傳感方法有：紅外線傳感、震動傳感、壓力傳感、超聲波和聲音傳感等。本次設計主要對銀行分為幾方面進行設計。銀行主要監測的位置有門口、窗戶和金庫。對于窗戶主要防止的是對犯罪分子對窗戶進行破壞，主要的測量對象為震動和壓力，相應的采用震動和壓力傳感器對其進行監測。門口的檢測主要是對門的破壞以及對有無人進入門口的檢測。所以在門口也要采用震動和壓力傳感器，同時還要采用紅外線傳感器對門口的監測。對于整個銀行內部要采用超聲波傳感器，銀行內部的總體情況進行監測。對于最重要的金庫會采用所有的傳感方式進行監測，同時還要采取高壓電防護系統。同時為了防止在休息時間發生內盜，給系統增加設定時間的功能。通過系統的鍵盤設定時間區域。使任何人在特定時間內都不能開啟金庫。當發生偷盜時，系統會以聲光報警的形式提醒在銀行內的人員。同時，系統通過公共電話網撥打110報警。以上就是該系統所實現的功能。
本次設計的銀行自動報警系統，彌補了當今市場上的報警系統檢測手段單一的缺點。在發生偷盜事件時，能夠迅速的發出報警，并且撥打110自動報警。該系統采用的多種傳感方法，擴大了監測的范圍。減少了銀行內的盲點。并且，本次的設計成本相對較低，準確性高。將會成為銀行保安系統中重要的組成部分。

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.
