1. INTRODUCTION

1.1OBJECTIVE OF THE PROJECT

Ours is a world of technology. With the development of this society many social evils are also increasing day by day. The anti social activities like theft, robbery and burglary are increasing day by day. Now a days one of the most anti-social activity causing headache to civilized society is theft. So it should be eradicated at any cost. The project our introducing here is how to prevent this theft in shops and other establishment. There are mainly 3 sections in our project. They are, time delay circuit, triggering circuit and alarm circuit. For this 3 ICS are mainly used. They are IC 4060 (IC1) for time delay circuit, IC 555 (IC2) for triggering circuit and IC UM 3561 (IC3) for alarm circuit. In addition to this a piezo electric element is used. It is a sensing element which can produce mechanical vibration even a light movement. These vibrations of the piezo electric element give sufficient trigger to the triggering circuit. The transistor used in this project are BC 547 (T1) used to amplify the piezo sensor signal and trigger the monostable IC (555). The second one is the triac BT 136 which complete the lamp circuit.

1.2 SCOPE OF THE PROJECT

Shutter Guards are the latest addition to the burglar proofing market, or should we say the shutter market. Although not originally designed to act as burgular deterrents test that have been performed have shown these shutters to be extremely difficult to break through, with pannels being locked in to place with latches, and louvers being secured in the closed position. In Europe, America and locally, these are particularly popular for lock up and go type residential applications. Over and above these benefits, the shutter guard look the same as any other type, they are also resistant to corrosive effects of outdoor applications and offer all the other qualities associated with shutters in general. These are now the fastest growing product in the industry. This provides a sense of security and privacy to the openings and door ways in any room. Dept. of EC MZC Kadamanitta

3.1 TIME DELAY UNITAs the name, time delay unit, is used to provide a particular time delay for the circuit operation. The front end of the circuit has a timer built around the popular binary counter IC CD 4060 (IC1). This IC (CD 4060) is used to provide a time delay of 15 minute for the remaining circuitry to turn on. The CD 4060 is the time delay generating IC. The CD stands for CMOS devices. It is a 16 pin CMOS IC. It consists of an oscillator section. The oscillator section allows the design of either RC or crystal oscillator circuit. All the stages of the ICS are master slave flip flop.

3.2 TRIGGERING UNITThe triggering circuit used in our project is the mono stable multi vibrator i.e. (IC2 555). A mono stable circuit produces a single output pulse when triggered. It is called a mono stable because it is stable in just one state. The duration of the pulse is called time period and the time period is determined by the resistor R1 and C1. ie. Time Period T R1 C1 T = 1.1 R1C1

3.3 ALARM GENERATING UNITThe third section is used to generate a siren when the shutter is try to break. For this purpose an 8 pin IC UM 3561 is used. With the help of this IC we can generate different type of siren as our needs. Let us look about the 3rd IC UM 3561.

3.31 UM 3561UM 3561 is an excellent ROM IC than can generate multi siren tones simulating police siren, ambulance siren, Fire brigade sire and machine gun sound. This 8 pin low power IC can work down to 2.4 volts. The UM 3561 is a low cost siren generator designed for use in toy applications. The IC has an inbuilt oscillator and tone selection pins. It is easy to make a siren generator with only a few external components.

Inside the UM 3561Inside the IC, there is an oscillator circuit and the frequency of oscillation is controlled by the external resistor connected to OSC 1 (pin 7) and OSC 2 (pin 8). A 220k resistor will give satisfactory results. The oscillation thus generated will be then transferred to a control unit. Which function based on the tone selection through the connections of SEL 1 (pin 6) and SEL 2 (pin 1). The control unit passes the signal to an address counter and then to the ROM. The tone pulse thus generated will be available from the output pin 3. Since the sound is weak, an amplifier is necessary to get loud sound. A single NPN transistor will amplify the sound.

3.4 LIGHTNING CIRCUITThe lightning circuit includes a lamp (60W). When somebody tries to break the shutter immediately this lamp is switched on. The trial BT 136 completes the lamp circuit by activating its gate terminal as in the circuit diagram.

3.5 TRANSISTOR AMPLIFIERIn the circuit the transistor is mainly used as an amplifier. Here the transistor T1 ie BC 547 is used to amplify the piezo sensor signal. When the piezo electric element is vibrated and triggers the monostable IC2. The base of this transistor is biased using a standard piezo element that act as a small capacitor flexes freely in response to mechanical vibrations. So that the O/p is (IC2) high till the pre-fixed time period (3 minutes).

3.6 PIEZO ELECTRIC SENSORThe piezo electric sensors are high performance buzzers that employ unimorph piezo electric element and designed for easy interpretation in various circuits. They have low power consumption in comparison to electro magnetic units because these buzzers are designed for external excitation.

5. CIRCUIT DIAGRAM DESCRIPTIONThere are mainly 3 sections in our project. They are time delay generating circuit, triggering circuit and alarm generating circuit. Among this the time delay circuit is considered as main circuit which controls the operation of its sub systems includes triggering circuit, alarm generating circuit and lightning circuits. Here we use three ICS for the proper operation of these 3 sections.

5.1 TIME DELAY CIRCUITThe front end of the circuit has a timer built around the popular binary counter IC CD 4060 (IC1). This IC CD 4060 is used to provide a time delay of 15 minute for the remaining circuitry to turn on. In the circuit diagram, the resistor R4 and R3 and the capacitor C2 will make the output high alter 15 minute. There is a diode D1 which inhibit the clock input (pin 11) to keep the output high till the power is switched off. An LED is connected in the 7th pin. The blinking of the LED indicate the Oscillation of IC1 .

5.2 TRIGGERING CIRCUITTriggering circuit used in this project is the monostable multi vibrator. ie (IC2 555/556). A monostable multi vibrator produces a single output pulse when triggered. It is called a monostable because it is stable in just one state. The duration of the pulse is called time period and it is determined by the resistor R1 and C1 that i.e. time period T = 1.1
