DEVELOPMENT OF RFID CAR DOOR LODKING SYSTEM

This week I research furthermore about the device principle of RFID device and GSM module. Firstly, I need to have to analyze the RFID information and its design to gather towards my FYP 2 project.

What is RFID?

Radio-Frequency Identification (RFID) is the use of radio waves to read and capture information stored on a tag attached to an object.  A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked.

 How does an RFID system work?

An RFID system is made up of two parts: a tag or label and a reader. RFID tags or labels are embedded with a transmitter and a receiver. The RFID component on the tags has two parts: a microchip that stores and processes information, and an antenna to receive and transmit a signal. The tag contains the specific serial number for one specific object.

To read the information encoded on a tag, a two-way radio transmitter-receiver called an interrogator or reader emits a signal to the tag using an antenna. The tag responds with the information written in its memory bank. The interrogator will then transmit the read results to an RFID computer program.

 There are two types of RFID tags: passive and battery powered.  A passive RFID tag will use the interrogator’s radio wave energy to relay its stored information back to the interrogator.  A battery powered RFID tag is embedded with a small battery that powers the relay of information.

In a retail setting, RFID tags may be attached to articles of clothing. When an inventory associate uses a handheld RFID reader to scan a shelf of jeans, the associate is able to differentiate between two pairs of identical jeans based upon the information stored on the RFID tag.  Each pair will have its own serial number.

With one pass of the handheld RFID reader, the associate can not only find a specific pair, but they can tell how many of each pair is on the shelf and which pairs need to be replenished. The associate can learn all of this information without having to scan each individual item.

and for GSM module itself

INTRODUCTION OF GSM MODULE

The GPRS/GSM Shield provides you a way to use the GSM cell phone network to receive

data from a remote location. The shield allows you to achieve this via any of the three

methods:

· Short Message Service

· Audio

· GPRS Service

The GPRS Shield is compatible with all boards which have the same form factor (and

pinout) as a standard Arduino Board. The GPRS Shield is configured and controlled via its

UART using simple AT commands. Based on the SIM900 module from SIMCOM, the

GPRS Shield is like a cell phone. Besides the communications features, the GPRS Shield

has 12 GPIOs, 2 PWMs, and an ADC.

SPECIFICATIONS

· Quad-Band 850 / 900/ 1800 / 1900 MHz - would work on GSM networks in all

countries across the world.

· GPRS multi-slot class 10/8

· GPRS mobile station class B

· Compliant with GSM phase 2/2+

· Class 4 (2W@850/900MHz)

· Class 1 (1W@1800/1900MHz)

· Control via commands (GSM 07.07, 07.05 and SIMCOM enhanced AT

Commands)

· Short message service

· Free serial port selection

· RTC supported with Super Cap

· Power on/off and reset function supported by Arduino interface
