Bank Security System

BACKGROUND

One day at the evening time I was talking with my uncle on telephone. He asked me

some question base on my learning means what are you learning? which type of

engineering are you doing? He ask me that have you made something new during your

engineering? That time I dont have any answer. But the time comes in final year. He is

officer in bank . once he told me that because of one rap our security system break and

because of that I have to go there at night. Can u prevent this and can make the system

batter than this?.that day I have decided to make security system of bank which is more

reliable than this one. We have combine all type of security system in this one. You can

secure all type of security which is useful for one organization. Simply anyone can say

that project of 50$ can prevent more than 50000$..!!!!

INTRODUCTION

We are going to make a that project which every one required. Now days it is very

important to prevent bank from thief. We are saving our money in bank so it is equally

important to save bank from thief. Now, day by day the number of larceny is increasing

so it is very important to prevent bank from burglar. This BSS saves your bank from

burglar. This circuit can prevent bank from thief. MSG automatically sent when any thief

came into your bank or they try to break lock of your Locker. Can you ever imagine that

you are getting MSG about yourbank security!!

Basically used for control actions.It is used to control the operation of machine using

fixed program that is stored in ROM/EPROM and that does not change over the life

time.

The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K

bytes of Flash programmable and erasable read only memory (PEROM). The device is

manufactured using Atmels high-density nonvolatile memory technology and is

compatible with the industry-standard MCS-51 instruction set and pinout. The on-chip

Flash allows the program memory to be reprogrammed in-system or by a conventional

nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a

monolithic chip, the Atmel AT89C51 is a powerful microcomputer which provides a

highly-flexible and cost-effective solution to many embedded control applications

The 3310 is a compact but somewhat heavy (133 g) phone featuring an 84 x 48

monochrome display. It has a lighter 115 g battery variant which has fewer features; for

example the 133g battery version has the start-up image of two hands touching while

the 115 g version doesn't. It is a slightly rounded rectangular unit that is typically held in

the palm of a hand, with the buttons operated with the thumb. The blue button is the

main button for selecting options, with "C" button as a "back" or "undo" button. Up and

down buttons are used for navigation purposes. The on/off/profile button is a stiff black

button located on the top of the phone. It has a very sturdy design which was a big

contribution for its success. However, radiation is high with SAR = 0.96 W/kg.

SENSOR

1. Infrared sensor

Infrared (IR) radiation is part of the electromagnetic spectrum,which includes radio

waves, microwaves, visible light, and ultraviolet light, as well as gamma rays and X-

rays. The IR range falls between the visible portion of the spectrum and radio waves. IR

wavelengths are usually expressed in microns, with the lR spectrum extending from 0.7

to 1000 microns. Only the 0.7-14 micron band is used for IR temperature measurement.

Using advanced optic systems and detectors, noncontact IR thermometers can focus on

nearly any portion or portions of the0.7-14 micron band. Because every object (with the

exception of a blackbody) emits an optimum amount of IR energy at a specific point

along the IR band, each process may require unique sensor models with specific optics

and detector types.

Working of IR Sensor:

The basic idea is to send infra red light through IR-LEDs, which is then reflected by any

object in front of the sensor.

Then all you have to do is to pick-up the reflected IR light. For detecting the reflected IR


6/23

light, we are going to use a very original technique: we are going to use another IR-

LED, to detect the IR light that was emitted from another led of the exact same type!

This is an electrical property of Light Emitting Diodes (LEDs) which is the fact that a led

Produce a voltage difference across its leads when it is subjected to light. As if it was a

photo-cell, but with much lower output current. In other words, the voltage generated by

the leds can't be - in any way - used to generate electrical power from light, It can barely

be detected. that's why Opams are mostly used for accurately detection of low voltages.

how the receiver of the sensor measures the distance of the intruding object:

As you know This is an electrical property of Photo Voltaic Cells(Light Emitting Diodes

(LEDs)) which is the fact that a led Produce a voltage difference across its leads when it

is subjected to light. So By using this property you can measure the distance of an

object

The output of these sensor is in Analog voltage format. It varies from Distance from

Object. So you can interface it with an ADC and then read this analog voltage by using

micro controller and calibrate it into any scale.

sharp sensor with Micro controller.

Advantages of IR Sensor:

1. Easily available in Market.

2. Easy to interface.

Disadvantages of IR Sensor:

1. Higly influenced by Environmental Noises like Ambient light, radiations etc.

2. Audio sensor


8/23

Audio sensor

The sound level channel works over the 55dB to 100dB range (approximately from

quiet conversation to a loud motorcycle). The human ear does does not respond equally

to all frequencies (it peaks at about 3kHz which corresponds to a baby crying). To allow

for this non linearity, sound level has been 'A-Law' weighted to approximately match the

response of the human ear. Typical uses for this channel include.

3. LDR:-

A or light dependent resistor or cadmium sulphide (CdS) cell is

a resistor whose resistance decreases with increasing incident light intensity. It can also

be referred to as a photoconductor.


9/23

A photo resistor is made of a high resistance semiconductor. If light falling on the device

is of high enough frequency, photons absorbed by the semiconductor give

bound electrons enough energy to jump into the conduction band. The resulting free

electron (and its hole partner) conduct electricity, thereby lowering resistance.

A photoelectric device can be either intrinsic or extrinsic. An intrinsic semiconductor has

its own charge carriers and is not an efficient semiconductor, e.g. silicon. In intrinsic

devices the only available electrons are in the valence band, and hence the photon

must have enough energy to excite the electron across the entire band gap. Extrinsic

devices have impurities, also called do pants, added whose ground state energy is

closer to the conduction band; since the electrons do not have as far to jump, lower

energy photons (i.e., longer wavelengths and lower frequencies) are sufficient to trigger

the device. If a sample of silicon has some of its atoms replaced by phosphorus atoms

(impurities), there will be extra electrons available for conduction. This is an example of

an extrinsic semiconductor.

SWITCH:

In electronics, a switch is an electrical component that can break an electrical circuit,

interrupting the current or diverting it from one conductor to another. [1][2] The most

familiar form of switch is a manually operated electromechanical device with one or

more sets of electrical contacts. Each set of contacts can be in one of two states: either


10/23

'closed' meaning the contacts are touching and electricity can flow between them, or

'open', meaning the contacts are separated and nonconducting.

A switch may be directly manipulated by a human as a control signal to a system, such

as a computer keyboard button, or to control power flow in a circuit, such as a light

switch. Automatically-operated switches can be used to control the motions of

machines, for example, to indicate that a garage door has reached its full open position

or that a machine tool is in a position to accept another workpiece. Switches may be

operated by process variables such as pressure, temperature, flow, current, voltage,

and force, acting as sensors in a process and used to automatically control a system.

For example, a thermostat is a temperature-operated switch used to control a heating

process. A switch that is operated by another electrical circuit is called a relay. Large

switches may be remotely operated by a motor drive mechanism. Some switches are

used to isolate electric power from a system, providing a visible point of isolation that

can be pad-locked if necessary to prevent accidental operation of a machine during

maintenance, or to prevent electric shock.

In the simplest case, a switch has two conductive pieces, often metal, called contacts

that touch to complete (make) a circuit, and separate to open (break) the circuit. The

contact material is chosen for its resistance to corrosion, because most metals form

insulating oxides that would prevent the switch from working. Contact materials are also

chosen on the basis of electrical conductivity, hardness (resistance to abrasive wear),

mechanical strength, low cost and low toxicity.


11/23

Sometimes the contacts are plated with noble metals. They may be designed to wipe

against each other to clean off any contamination. Nonmetallic conductors, such as

conductive plastic, are sometimes used.

Toggle switch

A toggle switch is a class of electrical switches that are manually actuated by a

mechanical lever, handle, or rocking mechanism.

Toggle switches are available in many different styles and sizes, and are used in

countless applications. Many are designed to provide, e.g., the simultaneous actuation

of multiple sets of electrical contacts, or the control of large amounts of electric current

or mains voltages.

The word "toggle" is a reference to a kind of mechanism or joint consisting of two arms,

which are almost in line with each other, connected with an elbow-like pivot. However,

the phrase "toggle switch" is applied to a switch with a short handle and a positive snap-

action, whether it actually contains a toggle mechanism or not.

This circuit is a small +5V power supply.The circuit will provide a regulated voltage to

the external circuit which may also I am required in any part of the external circuit or the

whole external circuit.The best part is that you can also use it to convert AC voltage to

DC and then regulate it ,simlpy You need a transformer to make the AC main drop

down to a safe value i.e 12-15 volts and then us a rectifier to convert AC into DC.

This circuit can give +5V output at about 150 mA current, but it can be increased to 1 A

when good cooling is added to 7805 regulator chip. The circuit has over overload and

therminal protection. The capacitors must have enough high voltage rating to safely

handle the input voltage feed to circuit. The circuit is very easy to build for example into

a piece of veroboard.

If you need other voltages than +5V, you can modify the circuit by replacing the 7805

chips with another regulator with different output voltage from regulator 78xx chip family.


15/23

The last numbers in the the chip code tells the output voltage. Remember that the input

voltage muts be at least 3V greater than regulator output voltage ot otherwise the

regulator does not work well.

Dont forget to check the pin diagram before connecting the IC.

WORKING

Most Nokia phones have F-Bus and M-Bus connections that can be used to connect a

phone to a PC or in our case a microcontroller. The connection can be used for

controlling just about all functions of the phone, as well as uploading new firmware etc.

This bus will allow us to send and receive SMS messages.

The very popular Nokia 3310/3315 has the F/M Bus connection under the battery

holder. This is a bit of a pain to get to and requires a special cable to make the

connection. The left picture above shows the 4 gold pads used for the F and M Bus.

The right picture shows the F-Bus cable connected to my Nokia 3310.


16/23

Nokia download cables are available from most mobile phone shops and some

electronics stores. The cable contains electronics to level convert 3V signals to RS232

type signals.

M-Bus is a one pin bi-directional bus for both transmitting and receiving data from the

phone. It is slow (9600bps) and only half-duplex. Only two pins on the phone are used.

One ground and one data. M-Bus runs at 9600bps, 8 data bits, odd parity, one stop bit.

The data terminal ready (DTR) pin must be cleared with the request to send (RTS). This

powers the electronics in the cable and I think it sets it for M-Bus operation.

F-Bus is the later high-speed full-duplex bus. It uses one pin for transmitting data and

one pin for receiving data plus the ground pin. Very much like a standard serial port. It is

fast 115,200bps, 8 data bits, no parity, one stop bit. For F-Bus the data terminal ready

(DTR) pin must be set and the request to send (RTS) pin cleared.

The F-Bus is bi-directional serial type bus running at 115,200bps, 8 data bits. The serial

cable contains electronics for level conversion and therefore requires power. The first


17/23

thing to do is supply power to the cable electronics and this is done by setting the DTR

(Data Terminal Ready) pin and clearing the RTS (Request to Send) pin.

whenever anyone try to get into your home you will get SMS in your mobile like

someone is trying to open your door (or window or locker).we have put IR sensorAnd

4 different sensors at different place(in prototype) and it will send command to

Microcontroller. Microcontroller will send command to Mobile and that mobile will send

SMS to your mobile, msg contain exact location of thief and msg would be continues

tracking location of thief and send SMS to user. In SAFE mode when thieves will break

your locker at that time police officer will get location of your Home. When you will reply

with LOCK your home will became locked (In smart home) and thieves will be trap in

your home. You also you reset whole security system by one SMS from remote place

How to send a SMS message with F-Bus?

Now that we know how to send frames on the bus, we should look at sending an SMS

message. It is not a hard process, once you can pack the message into 7-bit characters!

Let's say we want to decode the string 'hello'. First I have displayed 'hello' in

hexadecimal using the character map provided in GSM 03.38. For A to Z and numbers

its just the standard ASCII conversion.

h e l l o (ASCII characters)

68 65 6C 6C 6F (In hexadecimal)

1101000 1100101 1101100 1101100 1101111 (In Binary)

When dealing with binary, it makes life easier to write everything backwards. The first

byte in the string is on the right. The least significant bit is then displayed on the left with

the most significant bit on the left. Shown below is the same string of 'hello' just

displayed backwards. Then it's just a matter to dividing the binary values into bytes

starting with the first character in the string. (Start from right and go to left.) The first

decoded byte is simply the first 7 bits of the first character with the first bit of the second

character added to the end as shown below. The next decoded byte in then the

remaining 6 bits from the second character with two bits of the third byte added to the

end. This process just keeps going until all characters are decoded. The last decoded

byte is the remaining bits from the last character with the most significant bits packed

with zeros.

6F 6C 6C 65 68

1101111 1101100 1101100 1100101 1101000 (The ASCII characters shown in binary)

110 11111101 10011011 00110010 11101000 (The above binary just split into 8 bit

segments)

06 FD 9B 32 E8 (The 8 bit segments decoded into hex)

The message hello is therefore E8 32 9B FD 06 when packed.


19/23

When playing with sending SMS messages a lot of decoding is required. Therefore I

wrote a few small programs to automatically pack and unpack the data for me. The first

program allows me to input the string to be packed in the top memo box and when the

button 'Pack' is pressed the top string is packed ready to go!

This program below, will both unpack and then pack the message. It was used to read

the packed messages from my serial protocol analyzer. It also tests my subroutines in C

for both pack and unpack. Already for my AT90S8535 microcontroller!
