Design of a vehicle verification system for parking lots.

Abstract

The Vehicle Verification System seeks address the Security dilemma associated to the Vehicle parking lots basing its emphasis on a verification mechanism. The system looks at situations like when one has bypassed all your physical antitheft mechanisms like alarms, steering wheel lock, wood locks and is finally set to get away the parking premise with the vehicle. Here the parking lot has to come to your rescue, of course they will run to police and notify all traffic officials, which is quite tiresome and time demanding. This system does it better!! Of course it will not directly catch the thief, the system finds out who is exiting with which vehicle. First, you need to have an identification chip within your vehicle given to you by the owners of the parking facility. At the entrance the details of your car are captured and you are allocated an exit code that you produce during exit. This information is stored by the system. For demonstration, I used a transmitter circuit as my model car. The gate herein illustrated by the motor driven by the H-Bridge circuit depicts acceptance or denial to and from the parking there by opening or closing respectively. The hole effect sensors the reed switches, and the R-f setup are vital in identification of the vehicle there by triggering the corresponding action. The communications within the system are basically coordinated by the GSM shield. These include requisition of the exit code by the system, reply to the system requisition, and also notification of concerned in case of detected illegalities. This it does through the Power of AT commands (attention commands). A Modell has been provided to depict a parking lot environment. The microcontroller is the brain of this system. It does the thinking and initiates an action depending on how it interprets your input. For this Project I used the at mega 328 microcontroller programed in Arduino 6.1.8 IDE reasons for which shall further be explained herein.
