RFID Parking Garage Matt Nichols Tony Nichols

Problem Statement Current parking garage systems are time inefficient The payment process slows down entry and exit Payment tickets can be lost Payment can not be made prior to using the garage Only cash payment can be received Parking spots can not be reserved prior to visiting the garage

Key Engineering Requirements The user interface at entrance and exit must implement a red and green light to signal access allowed/denied The user interface at entrance and exit must implement a gate to physically allow/deny access. The web interface must be easy to navigate and understand. The system must protect user accounts with unique username and password combination. The system must link each account with an address provided by the user. The system must only allow one account per address. A user must allow user’s to add money to their account prior to visiting the parking garage. The system must only allow users with accounts to use the garage. The system must only allow users with accounts holding the minimum balance to use the garage. The system must calculate the time between entrance and exit to the parking garage, and remove the appropriate amount of funds from the user’s account following exit. The system must allow users to reserve parking for a specific date through the web interface for an additional fee. The system must keep track of the number of vehicles in the garage at a time by adding to the occupancy when users enter and subtracting from the occupancy when users exit. The system must include reserved parking spots in the occupancy count. The system must deny access when there are no available parking spots. The system must store records of each accounts usage of the system. The system must keep an accurate record of the money left on a user’s account by removing appropriate moneys.

Key Technologies Radio Frequency Identification Readers and Cards – Used to physically scan user accounts and time check at the garage entrance and exit MySQL Database – Used to create the database holding all of the user and garage data Ruby On Rails – Used to create the user and administrator web interfaces
