MALL SECURITY AND MANAGEMENT

NEED FOR PROBLEM:

Safety is the most important measure which is always concerned first. This project deals with mall management and security which is always need for the

security of the mall. The basic need is that the visitor should have an enjoyable

shopping experience .security concern also has an impact on shopping behaviour. Preventive measures in case of emergency so that people could evacuate easily.

PROPOSED ACTIVITIES:

The systems can be intended around an AT89S52 IC, a low-priced 8-bit 8052 based micro-controller and completely software controlled.

• All control programs could be created by employing the assembly language.

• Lastly, the mall security and management can be verified under various

situations to estimate its performance.

OBJECTIVE OF THE PROJECT:

• The main objective of this project is to provide a complete security for the

customers so that they could have a safe shopping experience.

• Keeps in track of the number of persons in the mall.

3

• Provides safety against hazardous materials.

• It gives safety alarm in case of fire or emergency.

BLOCK DIAGRAM AND ITS EXPLANATION:

Block diagram shows the working of the mall security and management.

Upon entry into the mall, count in the seven segment gets incremented and when

someone goes out the count gets decremented accordingly.

And when someone enters the mall with hazardous substance one led blinks

to indicate danger. When there is emergency in the mall as in case of fire or

4

something all the led blinks to indicate danger. And the count gets decremented

according to the exit.

CIRCUIT DIAGRAM AND ITS EXPLANATION:

In the circuit four switches are assigned to P3.0, P3.1, P3.2, and P3.6. a single Led

for metal detection is provided in the port P0.0, when someone enters the mall the

count gets incremented when switch 1 is pressed and displayed in a multiplexed

seven segment display, Which the ones and tens are assigned in P3.4, P3.5 and

when a person leaves the count value decreases by one which is given in switch 2.

In case of emergency interrupt service routine is provided and gets executed when

switch 3 is pressed. The last switch 4 is provided for metal detection.

SIMULATION:

Before running the code:

After running: (count increments and displays in port 2):

Conclusion and future scope:

• Thus the working of mall management and security is verified in software and

hardware implementation. This system has a lot of scope it can be implemented

in various fields as required. • Fire alarm can be further advanced by sending appropriate message to the

nearby fire station. Further advancements can be made with regard to the requirement of the mall.
