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.
