Course Project Description

Parking Garage Operations

Process

The process consists of a parking garage with an entrance and an exit door. The garage has 25 parking spaces. We assume the garage is empty at the beginning of the day. The parking garage manager starts the operation by pressing a normally open (NO) pushbutton. As soon as the process starts, a green light turns on at the entrance of the garage indicating that parking space is available. The number of parking vehicles in the garage is constantly monitored as vehicles enter or exit the garage. To indicate that a vehicle has entered the garage, a NO pushbutton is pressed. Another NO pushbutton is pressed if a vehicle leaves the garage. If the number of parked vehicles in the garage is 23 or 24, the green light at the entrance is turned off and a yellow light flashes continuously at the rate of one second on and one second off. If the garage is full, the flashing yellow light turns off and a red light turns on indicating that the garage is FULL. At this point if one or two vehicles leave the garage, the red light turns off and the flashing yellow light turns on. If additional vehicles leave the garage, the flashing yellow light turns off and the green light is turned on. At the end of the day, a normally closed (NC) pushbutton is pressed to stop the process and reset all counters. 

Parts Needed: 

1. Three NO pushbuttons as following: 
   • One to start the process, at address I1. 
   • One to represent a car entering the garage every time it is pressed, at address I3. 
   • One to represent a car exiting the garage every time it is pressed, at address I4. 
2. One NC pushbutton to stop the process, at address I2. 
3. One green LED at address O0. 
4. One yellow LED at address O1. 
5. One red LED at address O2. 
6. LogixPro PLC simulation software. 

Inputs 

I0:        NO START pushbutton
I1:        NC STOP pushbutton
I2:        NO pushbutton indicating vehicles entering the garage
I3:        NO pushbutton indicating vehicles exiting the garage 

Outputs 

O0:      Green LED
O1:      Yellow LED
O2:      Red LED 

Deliverables  

Read the statement of the project carefully a few times to fully understand the process. This is very important as you design the project in the next few weeks. Then describe the project in the Progress Report Template provided in YOUR OWN WORDS. Create a flow chart, bullet point list, or a table that describes the steps you have to take to design this project. For example to make pancakes for breakfast, you would do the following: 

• Gather all ingredients 
• Mix the flour, water, some milk in a bowl  
• Heat up a large pan lightly oiled 
• Pour small amounts of mix on the pan 
• Cook each side for 30 seconds 
• Pour syrup on the pancakes 
• Serve the pancakes. 

You should provide a similar bullet-point list, flow chart, or table for the course project. 

1) Module 1: Project - Understand the Description of the Project and Complete Module 1 Progress Report

2) Module 2 - Project: Program for a Blinking Light

3) Module 3 - Project: Program Up/down Counter Instructions

4)Module 4 - Project: Use Compare Instructions to Turn Different Lights On and Off Based on the Number of Cars in the Parking Garage.

5)Module 5 - Project: Complete the Ladder Logic Program for Course Project, Test for Functionality, and Submit the LogixPro rsl File Along with the Progress Report.

6)Module 6: Final Project Report
