HOME SECURITY USING PLC Ryan Badgett EKU, Dept. of Technology, CEN

2 OUTLINE Introduction Problem Statement Proposed Solution Results Conclusion Future Work

3 MOTIVATION Wanted to work with a PLC. The code of the PLC is simple. Had everything that I needed to work with. Never worked with the PLC in that way before. Wanted to do more hands on building.

4 INTRODUCTION PLC have been around for a long time. They are used mostly in factories controlling belts and motors. I am going to us the PLC to control motors to raise and lower gates and the door lock. I had to build a circuit that allows you to control the motor to change the direction so the gates can be raise and lowered.

5 PROBLEM STATEMENT It address the problem of someone braking into your house while you are away and having the chance to get away with your stuff. If they get stuck inside the house the police will be able to get them much easier. If they trigger the alarm before entering then nothing gets taken and they still might get cough.

6 PROPOSED SOLUTION Here are some of the problems that I solved along the way: I wanted to come up with something enjoyable and not very difficult to work with. I had to do some research on remembering how to program the PLC. I had to figure out how I wanted the program to run. For example when did I want the motors to turn on and for how long. Trying to combine the PLC language to the “real world” was a little difficult until I had some help.

7 PROPOSED SOLUTION CONT. I had to find a motor with enough torch to pull the gats up without stopping in the middle of the lift. It took more time to test and troubleshoot then writing the program I had to get the timer on the program to match up to when the gates dope to the windows I had to make sure the right motors and switch tripped and went in the right order. After I did that I had to run the program with everything together and verify that it worked the way I wanted it to.

9 RESULTS The results is you set the alarm, after a temperature switch is triggered it will go in lock down mode and everything will lock down. Once the police and homeowner gets there he can unlock the system.

10 CONCLUSIONS Everything worked out the way I wanted with the motor and gates after some modifications. It shows you how many ways you can use something like this in more way then in a factory I learned that sometimes you have to build more then what you tough you had to in or to get things working the way you need them to.

11 FUTURE WORK If I had more time I would have been able to put lights and different sensors I will take questions if anyone has any Thank You
