Pilot trolley method for trains
AIM:
To design a auto pilot trolley method for trains.
Base Technology: EMBEDDED
Abstract:
It is a very useful project. By using this we can reduce the more train accident. The trolley is communicating with the train using ISM based RF signal. 432.92 MHz frequency signal is used for communication. As we do the project we use this frequency. It will sense the object using the IR signal, bomb is detected using metal detector, track open is sensed using limit sense. All the information is transmitted using the RF signal to the train. After receiving the signal train is moved accordingly. Trolley is controlled from the train only. Here both the train and trolley is having the Tx and Rx. They are used to communicate between both.
