PROJECT ABSTRACT:Automatic Tollgate Opening Closing With Data logging through Zigbee

We can automate the toll bridge gate using the Radio Frequency Identification tag. An RFID tag is fixed with a vehicle. When a card comes in to the vicinity of the reader a charge of some amount will be detected from the particular person’s database and the toll bridge gate is automatically opened for the user to move. The Mechanical Model is constructed using a stepper motor.  The movement of the stepper motor is responsible for opening and closing action.

The Vehicle Details is sent to a nearby computer through Zigbee interface 2.4 GHZ for future reference. 

Hardware Requirements:

1.  PIC Embedded Microcontroller

2.  RFID Card with RFID tag

3.  Mechanical Model depicting Toll gate

4.  Stepper Motor for Opening and Closing Action

5.  LCD  Display

6.  Zigbee Interface

Software Requirements:

1.  Hitech C

Pic Microcontroller:

        PIC 16F877 microcontroller is used as a Processing unit.

RFID Card Reader:

        RFID Card Reader used to read the card number from the vehicle.

Power Supply:

        Generates +12V and +5vDC Power supply from 230VAC.

Mechanical Model:

        A mechanical model is constructed using a  stepper motor for gate opening and closing action

Stepper motor Driver:

        Used to drive the motor in forward and reverse direction as per the command given by the controller.

LCD Display:

        Used to display the actions in the screen. (Gate opened, Closed etc.)

Alarm and Alarm Driver:

        The voltage from the controller is not enough to drive the alarm. So an external transistor driver is necessary to drive the 12v alarm.

ZIGBEE interface:

        This interface is used to communicate to the computer. The vehicle details and the time is logged into the computer using this interface.
