This is a Research study under humanitarian technology ,
My first research paper and the one for which i struggled the most to get it work.The design is not yet implemented because of many contradictory designs but is soon to be used in future when government learns it to be the only design to work.
Abstract:
The objective of this paper is to propose an Analog circuit based design to control suicides in Indian metro railways. The proposed design is cheap, flexible and reliable. A laser beam is used to detect people jumping on the track which is connected to a light dependent resistor to send signal to control room of the station and the train arriving on that platform. Simple encoded transmitter and receiver are used to design the system. The design not only deals with stopping the train in such cases but also catching the people on an automatic driven mechanical tray.
INTRODUCTION
Metro Railway has become the best place for people to attempt suicide. At present the death toll counts 108 in Kolkata metro railway. Due to this abnormal mental activity of humans, metro railway services gets disrupted for many hours which makes the passenger suffer from loss of time and money. A lot of measures have been taken till now to control such accidents but none was found to be efficient enough because all the theories proposed till now deals with controlling the speed of train and power off the tracks.
A new method is implemented in this design, in which a laser beam of low intensity which will not be harmful to any human will run parallel over the edge of the platform if a citizen tries to jump on the track, laser will face obstruction and send a signal to control room as well as to the train incoming on the track. On receiving the signal the control room will switch off the power of tracks and the train on receiving the signal will automatically drive a mechanical tray to catch the person jumping on the track. This design deals with not just controlling but also saving the people attempting suicides.
