PREFACE

Token issue systems are ideal for banks, airports, public dealing offices, hospitals, doctor’s clinics, restaurants and other such places where people have to wait in line for their turn. These systems allow customers to wait without having to stand in line, once their number is displayed then only will they have to get in line for their turn. No need to make your customers stand in long queues in sunlight or rain and wasting time. Just distribute tokens on first come first serve basis and as soon as any counter is ready to provide services the person there just has to press one push switch to show the token number in displays. All models are easy to install, operate & maintain. Any ordinary electrician can do the installation quickly.

“A digital token is issued by cashier in bank to display the token number (etched on the tokens) which is issued to the customers against cheques for facilitating cash withdrawn from the bank. The cashier operates the display to show the token number against which he is ready to make the payment. The customer having the displayed token number can report to the cashier’s counter to receive the payment. In this way payment is made systematically to all desire customers without letting chaos to be created at the payment window. In this way the device serve the purpose of improving the performance of the banking system.

ABSTRACT

The project was really very challenging to us. Our “BANK TOKEN ISSUE SYSTEM” is not only a working model which already exists in market but a totally different research project that is yet to be evolving in market. Due to ever increasing demand of industrialization, such interfacing systems are becoming more and more necessary. We all have witnessed hazardous outputs due to the lack of proper time and proper management of data. This project is mainly designed for the purpose of management of data through the interfaces between various different units of companies in case of large plant consisting of more than one unit.

Automatic issue of token is requirement of any bank, increasing the banking requirement in India. It may be very important function of issuing the token to customer automatically. Token display systems are ideal for banks, airports, public dealing offices, hospitals, doctor’s clinics, restaurants and other such places where people have to wait in line for their turn. These systems allow customers to wait without having to stand in line, once their number is displayed then only will they have to get in line for their turn. No need to make your customers stand in long queues in sunlight or rain and wasting time. Microcontroller AT89S52, which is a low-cost and highly-reliable system, is used in this project. By making necessary changes in the software we can alter the working of the system.

We guarantee you that you will find yourself completely merged in this project after going through this project report.

1.2 ANALYSIS AND DESIGN OF HARDWARE

1.2.1 POWER SUPPLY:

Figure. 1.3

A power supply can by broken down into a series of blocks, each of which performs a particular function.

For example a 5V regulated supply is shown in the following figure

Each of the blocks is described in more detail below:

Transformer: steps down ac voltage + provides electrical isolation.

Rectifier: converts AC to DC.

Smoothing: smooth the AC to DC, ripples are there

Regulator: delivers fixed dc output without ripple.

A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors — the transformer's coils or "windings".

Basic PrincipleThe transformer is based on two principles: firstly, that an electric current can produce a magnetic field (electromagnetism) and secondly that a changing magnetic field within a coil of wire induces a voltage across the ends of the coil (electromechanical induction). Changing the current in the primary coil changes the magnitude of the applied magnetic field. The changing magnetic flux extends to the secondary coil where a voltage is induced across its ends.

14

1.3.2 REGULATOR:

Voltage regulator ICs are available with fixed (typically 5,12 and 15V) or variable output voltages. They are also rated by the maximum current they can pass. Negative voltage regulators are available, mainly for use in dual supplies. Most regulators include some automatic protection from excessive current (‘overload protection’) and overheating (‘thermal protection’).

Figure. 1.4 Many of the fixed voltage regulator ICs has 3 leads and look like power transistors such as 7805 +5V 1A regulator shown on the left. They include hole for attaching a heat sink if necessary.

1.3.3 MICROCONTROLLER 89S52:

15

Figure.1.5Features:

Compatible with MCS-51 products 8K Bytes of In-System Programmable (ISP) Flash Memory Endurance: 10,000

White/Erase cycles 4.0V to 5.5V operating range Fully Static operation:0Hz to 33MHz Three-level Program Memory Lock 256 x 8-bit Internal RAM 32 Programmable I/O Lines Three 16-bit Timer/Counter Eight Interrupt Sources Full Duplex UART Serial channel Low-power Idle and Power-down mode Interrupt Recovery from Power-down Mode Watchdog Timer Dual Data Pointer Power-off Flag Fast Programming Time Flexible ISP Programming (Byte and Page Mode)

Description:

The AT89S52 is low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of i-system programmable Flash memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is

16

compatible with the industry-standard 80C51 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 in-system programmable flash on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller which provides a highly-flexible and cost effective solution to many embedded controller applications.

The AT89S52 provides the following standard features: 8K bytes of Flash,256 bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, three 16-bit timer/counters, a six vector two level interrupt architecture, full duplex serial port, on-chip oscillator, and clock down to zero frequency and supports two software selectable power saving modes. In addition, the AT89S52 is design with static logic for operation. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt system to continue functioning. The power-down mode saves the RAM contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset.

Crystal Oscillator:

The on-chip crystal oscillator circuitry allows for utilization of quartzes both in the 6 and 13MHz range as the overall division ratio of the PLL can be switched between 64 and 128 via the CSEL pin according to the following table.

CSEL RF FREQUENCYOpen 6.xx MHzShorted to ground 13.xx MHz

1.3.4 LCD:

Figure. 1.6

This is the first interfacing example for the parallel port. We will start with something simple. This example dosen’t use the Bi-directional feature found on newer ports, thus it should work with most, if not all parallel port. It however dosen’t show the use of the status port as an input. So what we are interfacing? A 16 character x 2 line LCD Module to the parallel port. These LCD Modules are very common these days, and are quite simple to work with, as all the logic required for running them is on board.

1.3.6 RESISTOR AND CAPACITOR:

Resistor:

Figure. 1.8(a)

Register are element of electrical networks and electronic circuit and are ubiquitous in most electronic equipment. Practical resistors can be made of various compounds and films, as well as resistance wire (wire made of a high-resistivity alloy, such as nickel/chrome).

The primary characteristics of a resistor are the resistance, the tolerance, maximum working voltage and the power rating. Other characteristics include temperature coefficient, noise, and inductance. Less well-known is critical resistance, the value below which power dissipation limits the maximum permitted current flow, and above which the limit is applied voltage. Critical resistance depends upon the materials constituting the resistor as well as its physical dimensions; it’s determined by design.

Resistor can be integrated into hybrid and printed circuits, as well as integrated circuits. Size, and position of leads (or terminals) are relevant to equipment designers; resistors must be physically large enough not to overheat when dissipating their power. The ohm is a SI-driven unit of electrical resistance, named after George Simon Ohm.

20

CAPACITOR:

Figure. 1.8(b)

A capacitor or condenser is a passive electronic component of a pair of conductors separated by a dielectric .When a voltage potential difference exists between the conductors; an electric field is present in the dielectric.This field stores energy and produces a mechanical force between the plates. The effect is greatest between wide, flat, parallel, narrowly separated conductor.

An ideal capacitor is characterized by a single constant value, capacitance, which is measure in farads. This is the ratio of the electric charge on each conductor to the potential difference between them.

Capacitors are widely used in electronic circuits to block the flow of direct current while allowing alternating current to pass, to filter out interface, to smooth the output of power supplies, and for many other purposes. They are used in resonant circuits in radio frequency equipment to select particular frequencies from a single with many frequencies.

1.3.7 4x3 KEYPAD:

21

Figure. 1.9

Keypad provides a visually appealing way to enter numeric data to one’s control system.

The board is a series of pushbutton switches that provide structured input for measuring user input.

A 4x3 Keypad shown here has 7 I/O pins.

In context to this project, the keypad is used to enter relevant keys to give input i.e. to issue the token.

1.3.8 MAX232:

22

Figure. 1.10

Description

Operate from a single 5-v power supply with 1.0- μF charge-pump Capacitors. Operates up to 120 kbit/s Two drivers and two receivers ±30-v input Level Low supply current Application---Battery Powered system,Modems and Computers

To receive data from i.e. a PC, you need a level converter, like a MAX232, or use standard components and make your own level converter A level converter is needed because the Communication port of a PC switches the data between approx. -10 to +10 Volt.-10 Volt corresponds with a logical '0' (lo), 10 Volt corresponds with a logical '1' (hi), both on TTL level of 5 Volt, so can be connected directly to the i/o's of an AVR. The MAX232 can convert at a maximum speed of 120kbit/sec.

1.5 SOFTWARE DESCRIPTION

24

BASCOM-8051The Windows 8051 BASIC Compiler

INTRODUCTION

BASCOM-8051 is not only a BASIC Compiler, but also a comfortable. Integrated Development. Environment (IDE) running under Windows 95 and Windows NT.Such a development environment supports the whole process from coding and testing a program to programming the used micro-controller.Term BASCOM is used when no distinction must be made between BASCOM-8051 and BASCOM-8051. In all cases where a distinction is necessary, a few changes only are required to make the program work with the other family of microcontrollers. This is one important advantage of high-level languages.So as to prevent that work with BASCOM and the program examples are mere dry homework.

Memory

Every variable uses memory.

The available memory is 128 bytes. (Or 256 bytes for some chips)

From these 128 bytes a maximum of 32 are used for internal registers.

Some bytes are used by the stack. This depends on the statements you have used. Each 8 used bits occupy 1 byte. Each byte occupies 1 byte.

Each integer/word occupies 2 bytes. Each Long/Single occupies 4 bytes.

Use bytes when you can. (Not allowed for negative values)If your program uses less than 64 bytes you can use an 89C1051 as well. This chip only doesn’t have an UART for PRINT and INPUT statements.

You can also add external memory when you run out of variable space.

25

Program Compile:-

With this option you can compile your current program. Your program will be saved automatically before it will be compiled. The following files will be created depending on the Option Compiler Settings.

Filexxx.BIN Binary file which can be programmed into the uP.xxx.DBG Debug file which is needed by the simulator.xxx.HEX Intel hexadecimal file which is needed by some programmers.xxx.ERR Error file. (only when errors are found)xxx.RPT Report file.If an error occurs, you will receive an error message.

After you have pressed the Ok-button the cursor will be set to the line in which the error

occurred. The margin will also display a sign

Program compile shortcut :

Program Syntax Check:-With this option your program is checked for syntax errors. No file will be created except for an error file, if an error is found.

Program syntax check shortcut , CTRL + F7

Program Show result:-

Use this option to view the result of the compilation output for specifying which files must be created. The files that can be viewed are report and error.

File show result shortcut

Developing order

26

Start BASCOM; Open a file or create a new one; Check the baud rate and frequency settings for the target system; Compile the file; If an error occurs fix it and recompile (F7); Run the simulator and check if you don’t run out of stack space;

57

Initially, when turn ON the power supply, we can see four option in 20x4 LCD and we have to press * key to choose option from it. And in 16x2 LCD we can see the last token number issued & for what purpose it was issued.

58

Here after pressing * switch, we can see PRESS NUMBER in 20x4 LCD and we have to choose any number between 1 to 4.

59

Here after pressing key 4, we can see that, token number 5 is issued and for inquiry purpose it is issued, for three seconds only in 20x4 LCD.

60

Here in 16x2 LCD we can see the last token number 5 was issued and for inquire purpose it was issued.

61

Here now token no 6 is issued for new A/C opening purpose by choosing key 1,we can see it for 3 seconds only.

62

CHAPTER-5SOFTWARE VERIFICATION

63

SOFTWARE VERIFICATION

We can verify the software just as we are testing our hardware.

Here we have done verification by just providing the input to the controller through keyboard matrix by just pressing the keys one by one and checking the output at the controller ports which are connected to lcd and max 232.

We are getting the required voltages at the port pins according input.By this way we had verified our software after connecting with the hardware.

We have also verified on the pc by checking simulation results that are specified in chapter one.

CHAPTER-6ADVANTAGE,

DISADVANTAGE

65

ADVANTAGE:

Token Display System is a project liable to be used at the places where people have to wait in line for their turn. These systems allow customers to wait without having to stand in line.

All models are easy to install, operate & maintain. Any ordinary electrician can do the installation quickly.

DISADVANTAGE:

The system is controller based so any modification you want to do only skilled

person can do it.

LCD is not suitable for outdoor and industrial application.

66

CHAPTER-7APPLICATION

67

APPLICATION:

Token display systems are ideal for:

Banks Airports Public dealing offices Hospitals Doctor’s clinics Restaurants

68

CONCLUSION

From this project report we studied basic introduction of “BANK TOKEN DISPLAY SYSTEM”, basic block diagram and its circuit also studied A51 Assembler and coding. We studied how the project works and getting the result. It was opportunity for us to see how theory is put into practice. We learnt how some concepts of microcontroller were modified according to a particular industry or situation.

FUTURE EXPANSION

69

We can implement token number displays with automatic calling counter number display. Automatic increment of token numbers with display of calling counter number is ideally suitable for serving offices with many counters. No need to make your customers stand in long queues in sunlight or rain and wasting time. Just distribute tokens on first come first serve basis and as soon as any counter is ready to provide services the person there just has to press one push switch to show the incremented token number and respective counter number in displays.
