CORRIER MAIL BOX /PARCEL TRACING SYSTEM

As the technology is growing at a faster pace, everyone wants their services more reliable and fast. With this project sender and receiver of the courier can come to know at each point where their courier and when it will be reached

 

The parcel will be attached with an RFID tag. This tag contains a unique number. As the parcel travels many postal departments in various regions before reaching the destination, it will read in every region and send the message to parcel owner where the parcel is and when the parcel is reached to destination. Every postal department contains the RFID reader and GSM modem.

 

RFID tags are categorized as either active or passive. Active RFID tags are powered by an internal battery and are typically read/write, i.e., tag data can be rewritten and/or modified. An active tag's memory size varies according to application requirements; some systems operate with up to 1MB of memory. Passive RFID tags operate without a separate external power source and obtain operating power generated from the reader. This project uses passive tags. Read-only tags are typically passive and are programmed with a unique set of data (usually 32 to 128 bits) that cannot be modified. The reader has three main functions: energizing, demodulating and decoding. The antenna emits radio signals to activate the tag and to read and write data to it.

 

A GSM modem provides the communication interface. It transports device protocols transparently over the network through a serial interface. A GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.

 

The reader reads each and every parcel and sends the unique number written in the tag to the microcontroller. The microcontroller displays this number on LCD along with the area it is currently in and sends a message to his mobile where the parcel is. The users can check the current location of the parcel in the internet. Thus, there is no worry that the parcels are reached safely or not. The controlling system continuously updates the current location of the parcel.
