Currently, I am working on a project based on train collision avoidance system using IoT and RFID. For a simple prototype design, which board is more convenient as a beginner?
The block diagram for the unit inside the train and also unit at the railway cross gate is attached hereby.
In this project what we are aiming to do is to give an effective solution to avoid train collision. RFID tags are attached to the track and each time the RFID reader inside the train read this unique number which is sent to a base station and if two trains are on the same track then the base station immediately sends this message to the train and immediate braking action is initiated. In case the internet is down then I am planning to use an RF transciever for direct communication between the trains.
The other unit is the one that will be installed at the railway cross gates. Here I am planning to use a camera along with an LDR module to make the whole system at the railway cross gate unmanned.
