Project Name : TECHNO TRACK (Safety in the hands of technology)
Theme Name : Transport & Communication
Aim of the Project : To spread awareness against frequent train accidents suggesting the ways to prevent them.
Project At Glance:
1. Anti Collision Device
2. Automatic Railway Crossing Gate
3. Automatic Signals
4. Automatic switch on/off the light inside the tunnel at the time of crossing the train.
Principle Of The Project: To stop supply of the electric current in the Train engine through IR electronic sensor and OAPM-IC, Functioning of Automatic Railway Crossing Gate, on the basis of electromagnetic induction phenomenon and functioning of Automatic Signals and Automatic switch on/off the light inside the tunnel at the time of crossing the train are based on two relay.
Main Parts:
IR (Infrared rays) sensor, OPAM 325 IC, 6V relay, LED (light emitting diode), Transistor, Variable resistors
Function of Different Parts:
Ir Sensor: Its function is to detect any object which comes in its region, normally it provides zero voltage but when any object comes in its field it provides 3-5 V as an output.
Opam 325 IC: It operates with set point voltage level like 1V when trigger crosses 1V than IC operates automatically and provides output.
6 V Relay: Here Relay is functioning as a switch only which is connected between output of OAPM and electric motor and according to Sensor level current supply will continue or off by this relay
Transistor: Transistor is functioning as a relay driver because IC output gives very small current while relay required current approx. 1A.Hence Transistor amplifies the current.
Variable Resistors: All resistors are used only for controlling the electric current.
Working: Our project is working on fully electronic control logic system. In this project we have two main parts one is IR Sensor and other is OPAM IC . OPAM IC operates with IR Sensor. As we know that IR Sensor provides Zero voltage, when any object comes in the field of IR Sensor its output voltage becomes high; approx. 3-5 V due to this OPAM – IC operates with trigger voltage at any level between 3-5 V and finally electric current stops flowing through electric motor.
Automatic Railway Crossing Gate is functioning on the basis of Electromagnetic induction phenomenon. Functioning of Automatic Signals and Automatic switch on/off the light inside the tunnel at the time of crossing the trains is based on two relay.
