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.
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.
