Anti Collision Mechanism

To implement this project we will need RFID(Radio Frequency Identification) using which we can label product with information.It is basically a wireless non contact system that uses radio frequency electromagnetic fields to transfer data. Owner of that information can access that information without having direct contact with that particular product.

What is the use of RFID ?
When implemented successfully each item in inventory carries its information on itself and make automation extremely easier. As we saw in Pranav Sixth sense technology about its possibility and uses when every item tells about its price, reviews and other useful information.

So what's the problem?

This system works great when used with only one information spreading tag in the environment but when multiple product reflect and modulate incoming signals.

How it works?

It works in two steps, in first step we will perform modulation between  High frequency Pseudo random sequence with Data Sequence to get high frequency data sequence and in second step we will modulate Incoming waveform with Pseudo random sequence to get original data.

Step 1.) Pseudorandom Sequence + Data Sequence ----> Resultant Output

Step 2.) Resultant Output + Pseudo random (High Frequency) -----> Original Data
