HOME SECURITY USING PLC Ryan Badgett EKU, Dept. of Technology, CEN
OUTLINE • Introduction • Problem Statement • Proposed Solution • Results • Conclusion • Future Work
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.
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.
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.
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.
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.
HYPERLINKS • PLC Project • Code
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.
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.
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 • Email: ryan.badgett@gmail.com
