This proposed system improves the presently used parking system by enhancing its security features and simplifying the parking process by eliminating the need for manual intervention. For authentication and owner car identification, the parking system uses Near Field Communication (NFC) technology. NFC is a set of standards for smart phones and similar devices to establish radio communication with each other by bringing them into close proximity or touching them together, usually no more than a couple of inches. NFC Module is widely present in today s smart phones and thus can be used to eliminate the need for parking tokens and/or cards. On the other hand, the automation and space management is managed by the ARM microcontroller by controlling the mechanical motors in transporting the car to an appropriate parking space. Keywords: ARM Cortex M3, LCD display, NFC, PN532, Rack and pinion 1. INTRODUCTION To understand the need and advantages of using Near Field Communication in the parking system and also to understand the basic idea of proposed system, let s take a look at the two things separately. 1.1 NFC Near field communication (NFC) is a set of standards for smart phones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually not more than a few inches. Present applications include contactless transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi or Bluetooth. Communication is also possible between an NFC device and an unpowered NFC chip, called a "tag". 201

2 NFC is a means of sending data over radio waves. In that sense it is similar to Wi-Fi or Bluetooth, but unlike those protocols (and like RFID); NFC can be used to induce electric currents within passive components as well as just send data by communicating with active devices. NFC can work with passive devices that don't require their own power supply i.e. a NFC tag. NFC's data-transmission frequency is 13.56MHz. NFC can transmit data either at 106, 212 or 424 Kbps (kilobits per second). NFC standard has three modes of operation: the peer-to-peer mode that lets two smart phones swap data, a read/write mode in which one active device picks up info from a passive one, and card emulation, in which an NFC device such as a smart phone can be used like a contactless credit card [2]. 1.2 Automated Car Parking System An Automated Car Parking System is a mechanical system designed to minimize the area and/or volume required for parking cars. It is like a multi-story parking garage, it provides parking for cars on multiple levels stacked vertically to maximize the number of parking spaces while minimizing land usage. This Automated System, however, utilizes a mechanical system to transport cars to and from parking spaces (rather than the driver) in order to eliminate much of the space wasted in a multi-story parking garage. It is more similar to an automated storage and retrieval system for cars. 2. SYSTEM ARCHITECTURE The parking system is fully automated and can be called as a robotic valet parking system. The driver drives the car into an entry (transfer) area. The driver and all passengers exit the car. The driver taps his NFC enabled smart phone at an automated terminal nearby. The NFC Reader terminal reads UID of the NFC enabled smart phone then sends the commands to microcontroller and microcontroller assigns an empty parking slot. When driver and passengers have left the entry area, the mechanical system lifts the car and transports it to a pre-determined parking space in the system. The rack and pinion mechanism for linear motion is used to transport the car to the parking slot. Since the structure of the parking garage is circular, linear motion along X-Y direction and rotational motion in X plane is used to park the car. Fig 1: Proposed parking System 202

3 Fig. 1: Rack and pinion arrangement The driver retrieves a car by again tapping his smart phone into an automated NFC reader terminal. The system calculates the payment to be collected according to the parking period. The driver makes the payment. The Parking System then lifts the car from its parking space and delivers it to an exit area using the same rack and pinion mechanism. Also, the retrieved car has been oriented according to the exit route to eliminate the need for the driver to back out. Thus this fully automated Parking System theoretically eliminates the need for parking attendants by using NFC as means of Authentication and owner car identification. 3. SYSTEM WORKING While parking the driver places his car at the starting platform at the entrance of the parking lot. He then brings his NFC enabled smart phone or a NFC tag near (5cm approx.) the NFC reader module controller. The NFC reader module is based on PN532 breakout board which consists of PN532 reader/writer IC. Every tag or smart phone has its own Unique Identity Number (UID) which is used for authentication. The NFC breakout board reads the 7 byte identity number from the tag or NFC enabled smart phone and forwards it to ARM Cortex M3 microcontroller using Serial Peripheral Interface (SPI) mode. ARM microcontroller compares this UID with other UIDs stored in the memory. If there is no match the microcontroller understands that there is a new car which needs to be parked and the microcontroller initiates the parking process else it understands that the car which has already been parked and needs to retrieved and it initiates the retrieving process [1] [3]. 203

4 Fig 2: Block Diagram of the system During the parking process the microcontroller first stores the UID in the memory, calculates the nearest empty slot and waits for the user to press start button. When the start button is pressed the microcontroller gives commands to the motor driver circuit accordingly and the LCD interfaced with cortex M3 will display Parking in Progress. The motor driver circuit drives the motors according to the commands received and the car is parked at the nearest empty location assigned by cortex M3. After the car is parked the LCD will display Parking Successful. The microcontroller also stores the location of parking slot corresponding to the specific UID in the memory. During the retrieving process the microcontroller compares the UID with the existing UIDs in it memory. When the match is found the microcontroller pulls out the location of the car corresponding to the specific UID from its memory. Accordingly it gives command to motor driver circuit to fetch the car and the LCD will display Retrieving in progress. The LCD will display Car retrieved successfully after the car is fetched from its parking location and brought back to the starting platform. The microcontroller will than delete that particular store UID from its database and will wait for next input from the NFC breakout board. The whole ARM Cortex M3 programming is done in high level language using Kiel uvision IDE. 204

As every NFC tag and NFC enabled smart phone has unique ID so the system cannot be deceived by a forged ID. iii. Parking space width and depth (and distances between parking spaces) are drastically reduced since no allowance need be made for driving the car into the parking space or for the opening of car doors (for drivers and passengers). iv. No driving lanes or ramps are needed to drive the car to/from the entrance/exit to a parking space. v. The parked cars and their contents are more secure since there is no public access to parked cars. vi. Minor parking lot damage such as scrapes and dents are eliminated. vii. Driving around in search of a parking space is eliminated, thereby reducing time and fuel consumption and thus the engine emissions. 5. LIMITATIONS i. The user needs to carry NFC enabled smart phone otherwise a NFC tag need to provided to the user which becomes an additional liability to the parking system. ii. The initial cost of setup is high. iii. Since there is a single entry and exit point there will be traffic congestion if several cars arrive simultaneously. 6. FUTURE SCOPE While working on the evolution of the system and exploring the ways in which the system can be designed, we came across few new features that could be added through little alterations in the system. Following are the things that can be done with few modifications. i. NFC parking meter can be integrated in the system which can be used to make payments using NFC enabled smart phone. The fee is charged to a credit or debit card associated with the mobile phone number. ii. Multiple entry and exit points can be constructed to reduce the traffic congestion thereby saving time. 7. CONCLUSION Thus we have provided a comprehensive review of our Automated Car Parking System. It helps us to alleviate the shortcomings of current parking systems. Also using NFC for authentication makes the system hassle free for the user as he need not take care of additional parking tokens as his NFC enabled smart phone works like one. And even though the initial cost of setup is high, it is worth as it provides fully automated system with better space management than conventional systems. 205
