INTELLIGENT SECURITY SYSTEM
To make an INTELLIGENT SECURITY SYSTEM based on 8051 8-bit microcontroller.It has various household and official applications which are used in our day to day life. So it has practical importance in todays life for various security purposes. Now a days it is used on the ground level means it is used in many works today.
Programmable number lock system is a high security number lock system that can be
used as Intelligent security system. The present system is very user friendly.
This system is a combination of software and hardware at its best. We have used an 8051 Microcontroller kit for interfacing our system.
In the present design we can lock a door. The door is locked using a four digit code (password). The code can be set as per the user’s desire, hence the name ‘PROGRAMMABLE’.For the door to be unlocked the user should enter the code that has been entered when the door was locked. The door will unlock and SEVEN SEGMENT will displays ‘P’ with BUZZER sound. In case the user enters wrong code BUZZER will be activated but this time the volume will be much less as compared to previous case.
DESCRIPTION OF BLOCK DIAGRAM
The description of the block diagram is given below:
THE SYSTEM HAS THREE UNITS, namely:
(i) Keyboard unit
(ii) Display unit
(iii) Control unit
(i) Keyboard section:-
The keyboard unit consists of 10 number keys, 1 unlock key and 1 lock key. These are all push button switches. This unit is used to enter the codes into the System. It is also used to request the system to lock/unlock the selected device.
(ii) Display section:-
The display section contains 1 segment display. This unit displays the status of System
(a) when seven segment displays ‘E’:- Then it indicates that we have to enter the Code in order to lock the device.
(b) when seven segment displays ‘C’:- Then it indicates that the system is locked.
© when seven segment displays ‘P’:- Then it indicates that the system get opened.
(d) when seven segment displays ‘F’:- Then it indicates that the system will remain
locked as you have entered the wrong password.
This section is detachable . If detached it does not effect the working of the whole system.
