AUTOMATIC GATE OPENING SYSTEM FOR VEHICLES WITH RFID OR PASSWORD

This journal will explain automatic gate opening system for vehicles with RFID or password. Hence, the main objective of this project is to provide security in an organization by allowing only the authorized personnel to access the secure area. Besides that, the security of any organization is a priority for the authorities. So the concern is for the physical property and also for the intellectual property. For this reason only the authorized person with a valid RFID tag is allowed into the secured premises. Furthermore, this tag contains an integrated circuit that is used for storing and processing information, modulating and demodulating the radio frequency signal that is being transmitted. Thus, once the person shows the RFID tag to the card reader it scans the data present in the tag and compares it with the data present in the microcontroller.

So when the data matches with that in the microcontroller, the load will be turned ON which is operated by a relay being driven from the output of the microcontroller. By the way if a valid tag is swiped then the system displays a message “AUTHORIZED” else it states “UNAUTHORIZED” and doesn’t allow access. The lamp is used as an indication besides the LCD display.

The system was includes power supply, LCD display, RFID reader, microcontroller, relay to switch the computer. LCD display consists of one LCD and a potentiometer. RFID reader consists of a RFID reader and a resistor.PIC16F877Ais used us a microcontroller. The function relay is to switch consists of MAX232, CONN-D9F, capacitors, resistor, BC547, and OMIH-SH-105L.

Hence, the power supply is provided to the system. So when the student shows the ID card, the RFID reader reads the data from the card and it is transferred to the microcontroller. By the way, it decodes the data from the reader and checks whether the card is valid or not. So if the card is valid, LCD displays it. The microcontroller will transfer the control to the PC through relay.
