    • A PRESENTATION ON ACCESS CONTROL SYSTEMPREPARED BY:Mody Devansh D. (06-ECG-03)Kukadia Pritesh M. (06-ECG-22)GROUP NO:8INTERNAL GUIDE:Mr. J.N. PATEL 1/15
    • LIST OF CONTENTS Introduction of Project Block Diagram Circuit Diagram Component Details Working of circuit Flow chart Software details 2/15
    • INTRODUCTION OF PROJECTNow a days, a problem of security is very much important everywhere in the world. So, in large firms or companies, to make protect ofentering of unauthorized person or to secure their important section,they generally use this type of security.This project, AN ACCESS CONTROL SYSTEM provides a facility ofsecurity. This type of security lock is generally attached at the mainentrance door of the firms. By using this type of security, onlyauthorized fellow can enter. It is quite easy in installation and use. Through this, one can allocatemore number of passwords to many fellows. It is easy to use as thefellow don’t need to carry any type of id card or chip etc. 3/15
    • BLOCK DIAGRAM AND DESCRIPTIONELECTRICAL LOAD LOADS DRIVER KEYPAD 8051 ALARM ALARM DRIVER 4/15
    •  First of all a user enters a password by a hexkeypad. Micro controller checks password and then givesaccording output. If the password is correct then it opens the door. If the password is wrong then it gives output tothe alarm. 5/15
    • CIRCUIT DIAGRAM AND DESCRIPTION LCD 6/15
    •  When the power supply is switched on, then thewhole circuit starts working. Then in LCD, the name of company is displayedand the person is asked to enter the password.The password is entered through a hex keypad.The microcontroller compares that password withthe already saved database of employeesinformation. 7/15
    • If it matches with any of the saved password, thenmicrocontroller gives output to the LCD.Then in LCD, the name of employee, hisdepartment, his employee number, etc are displayed.Parallel, the microcontroller gives output to the DCmotor to open the door.If the password doesn’t match with any passwordthree times, then microcontroller displays in LCD thatyour password is wrong, and it gives output to thebuzzer. 8/15

    • MAIN PCB 10/15
    • WHY HEX KEYPAD?A general 3×2 matrixkeypad contains only0-9 keys.Whereas a hex keypadcontains 0-9 keys and also itcontains A,B,C,D,E,F keys.So it provides morenumber of combination ofPasswords to the firms. 11/15
    • POWER SUPPLY SECTIONA supply is given from 230v AC through a 12v adepter.Then it is given to the bridge rectifier. The output ofrectifier is given to voltage regulator IC through filtercapacitors. 12/15
    • SOFTWARE DETAILSKEIL µ VISION 3.0.3.KEIL SOFTWARE IS USED TO PROVIDE YOU WITH SOFTWAREDEVELOPMENT TOOLS FOR 8051 BASED MC. WITH THE KEIL TOOLS YOUCAN GENERATE EMBEDDED APP FOR VIRTUALLY EVERY 8051DERIVATIVE. 13/15
