INTRODUCTIONINTRODUCTIONDigital code lock or an electronic combination lock can be used in gates and doors of restricted areas to permit only the authorized individuals in the area. The access is granted to them only after pressing the correct assigned code of the system.

Chapter one

To design a cheap and effective security system for buildings, cars, safes, doors and gates etc.

To experiment the application of the digital locking

system.

To prevent unauthorized person from having access to ones properties through the use of codes.

LITERATURE REVIEWLITERATURE REVIEW

In 1857 James Sargent invented metal key changeable combination lock.

In 1958, the first electronic combination lock was invented.

METHODOLOGYMETHODOLOGYPrinciple of operation of Digital Locking System:

• The power supply is provided first to the hardware and through voltage regulator, the circuit components receive their proper supply voltage.

• After that, the LCD displays the required BCD code and asks to the person to show the tag.

• The code is received by the module and checks the code availability.

• For correct code, LCD displays the CORRECT PASSWORD

• For wrong code, LCD displays INVALID PASSWORD.

RESULTS AND DISCUSSIONSRESULTS AND DISCUSSIONSResults:

The prototype door security system developed in this project

did well in achieving its original goals.

In the beginning, the system will boot up with display on the

LCD screen prompting the user to enter pin code.

The total project works perfectly and has negligible amount

of unexpected functioning.

RESULTS AND DISCUSSIONSRESULTS AND DISCUSSIONS

Applications:

Industrial facilities Commercial buildings , Airports, civil transportation Convention halls Psychiatric care centers Museums and fine art galleries , Ware houses Technology centers Government and military Long term care facilities Drug rehabilitation centers

RESULTS AND DISCUSSIONSRESULTS AND DISCUSSIONSAdvantages and disadvantages:

Advantages- • Improved Productivity and Cost Avoidance. • Decreased Cycle Time and Taking Costs Out. • Reduced Rework. • Reduced Business Risk & Control of Assets. • Improved Security and Service.

Disadvantages-•This is not an economical way of providing control at various locations at a time.•Workers may started to practice buddy punching for their co-workers.

CONCLUSION AND RECOMMENDATION CONCLUSION AND RECOMMENDATION

Conclusion:

As the technology is going on developing day by day, we prefer things to be done automatically and in the same way our projects reduces the work to mankind.

For the well-being of lives and properties of individuals, a cheap and effective way of security system for buildings, cars, safes, doors and gates has developed. We, therefore experiment the application of electronic devices as locks.

The general operation of the system and performance is dependent on the key combinations.

CONCLUSION AND RECOMMENDATIONS CONCLUSION AND RECOMMENDATIONS Recommendations:

The development of this technology for the field of security system is not only possible, but it could even prove to be very useful.

It is evidence that the use of mobile phones with the right circuitry can be used to operate a security system, since the mobile phone in today's world; it is an access device a lot easier and affordable to obtain as opposed to specially fabricated keys and smart-cards.

The ability of the system to accesses a secure place (Home, office, ATM etc.) remotely almost anywhere in the world is a plus since technology has made the world a global village.
