SOLAR POWERED AUTOMATIC RAILWAY GATE
ABSTRACT:
This mainly aim is to preventing accidents at unnamed level crossings where large many accidents take place every day. The automatic railway gate controller makes use of two sensors placed at both sides of the gate placed at a particular distance. The sensor detects the arrival of train and sends signal to close the gate and similarly the sensor at the other end detects the departure of the train to open the gate again for public use. The usage of this automatic railway gate controller will largely reduce the accidents at unmanned level crossings and provide immense safety. This report deals with the designing and operation of this automatic au tomatic railway gate controller. Railways being the cheapest mode of transportation are preferred over all the other means .When we go through the daily newspapers we come across many railway accidents occurring at unmanned railway crossings. This is mainly due to the carelessness in manual operations or lack of workers. We, in this project have come up with a solution for the same. Using simple electronic components we have tried to automate the control of railway gates. As a train approaches the railway crossing from either side, the sensors placed at a certain ce rtain distance from the gate detects the approaching train and accordingly controls the operation of the gate. Also an indicator light has been provided to alert the motorists about the approaching train.
Using the same principle as that for gate control, we have developed a concept of automatic track switching. Considering a situation where in an express train and a local train are travelling in opposite directions on the same track; the express train is allowed to travel on the same track and the local train has to switch on to the other track. Indicator lights have been provided to avoid collisions .Here the switching operation is performed using a stepper motor. In practical purposes this can be achieved using electromagnets. .
