ENSURING SAFETY FOR INDIAN RAILWAYS THROUGH GPS : 

ENSURING SAFETY FOR INDIAN RAILWAYS THROUGH GPS Presented by J.HINA AAFREEN

TABLE OF CONTENTS : 

TABLE OF CONTENTS INTRODUCTION STATISTICS ON RAIL ACCIDENTS WHAT IS GPS? APPLICATION OF GPS WHY GPS HERE? COMPONENTS AND FUNCTIONS PRINCIPLE OF WORKING ONBOARD UNIT DESIGN IMPLEMENTATION NEEDS CONCLUSION

INTRODUCTION : 

INTRODUCTION Indian railways is the biggest railway network in the world On the other hand it has faced large number of accidents due to negligence,techinical fault etc…. Even though we have got many techniques of preventing these accidents NO METHOD CAN BE MORE EFFECTIVE AS THAT OF GPS

WHAT IS GPS : 

WHAT IS GPS GPS – Global Positioning System A network radionavigation system formed from a constellation of minimum of the 24 satellites rotating in 6 orbitals and their ground stations

APPLICATION OF GPS : 

APPLICATION OF GPS Mapping and GIS Data Capture Navigation Vehicle Tracking Mining & Construction

WHY GPS HERE ? : 

WHY GPS HERE ? To avoid rail accidents It is highly efficient The system is highly reliable and informations are highly secured systems promise radical improvements to many systems that impact all people main function of GPS is to get the interconnectivity of the various points in the track

PRINCIPLE OF WORKING : 

PRINCIPLE OF WORKING Whenever a train will move over the track there will be vibrations that will be created on the track. These vibrations that are produced on the track are dependent on the speed of the train, load or the weight of the train A software traces these vibrations using microphones and convert these vibrations in such a form that they can be compared with the already existing data of the database If there will be any problem on the track, bridge etc. such as the removal of the fish plates the vibrations produced from the train will change (they will either get damped or will get excited which is a noticeable change from the ideal case)

PRINCIPLE OF WORKING : 

PRINCIPLE OF WORKING If the obtained data and the stored data are the same then normal signal is send to the receivers from the satellite If the vibrations from the track are more or less then emergency signal is send to the receivers

COMPONENTS & FUNCTIONS : 

COMPONENTS & FUNCTIONS Microphone sensors Needs critical selection as huge amount of the vibrations or the noises are created that are not possible to get recognized from a large distances Traces the vibrations and sends to DBMS Proposed sensor-CARBON SENSORS used in telephone Fiber optic wires Transmits the traced vibration data to DBMS quickly

COMPONENTS & FUNCTIONS : 

COMPONENTS & FUNCTIONS Software and DBMS programs that can perform some tasks that are assigned to them DBMS is the Data Base Management System which can store a huge amount of the data in them S/W converts vibrations from sensors into some graphical forms and transfers to DBMS which contains preloaded data that are analysed in normal conditions

ONBOARD UNIT DESIGN : 

ONBOARD UNIT DESIGN continuously measure different parameters, tag the data with time and position information, reports irregular conditions consists of communication satellite antennae, satellite positioning antennae , the on-board receiver system and communication interface devices, etc

IMPLEMENTATION NEEDS : 

IMPLEMENTATION NEEDS Need of the towers for the transfer of the data to the various destinations A high tech visual display system to show the actual position of the trains along with other details like visual and audio warning systems Receivers and the transmitters tuned to proper frequencies and in accordance to the network The train driver’s cabin must be such that the driver will come to know about the track,weather, bridges and constructional status in advance Good communication system. This can be achieved by the use of the GPS ITSELF

OPERATING FREQUENCY : 

OPERATING FREQUENCY Uplink frequency-5.925 to 6.425 GHz Downlink frequency-3.700 to 4.200 GHz may change as per the advancements that are made and the system requirements

TRAIN COLLISION : 

TRAIN COLLISION

REMEDY THROUGH GPS : 

REMEDY THROUGH GPS Consider two trains of same or different weights,speeds approaching towards each other in the same track with GPS n/w installed in it The microphone sensors traces the vibrations 35km prior to its arrival As two trains are approaching in the same track the vibrations gets excited This produces emergency signal with alarm and this is transmitted to the control rooms and to loco

EXPECTED BENEFITS : 

EXPECTED BENEFITS Railway Safety Automation in the Work Reduction in the Stress Levels because of the good equipments and machinery Time Delays: As every time the position of the train will be known thus there will not be any time delays Train Traffic Control: due to continuous monitoring of the trains there will be a good train traffic control

HOW GPS OVERCOMES : 

HOW GPS OVERCOMES The implementation time is large and the cost is high to some non technocrats A survey says that the total loss for our government rates to few hundred crores So just by investing a small sum of this loss,the accidents and losses can be overcome once for all

CONCLUSION : 

CONCLUSION The benefits and advantages of the proposed method outnumber the problems and disadvantages. By considering this method for the most important transport system in India the most valuable ‘human life’ and the national property can be protected Thus the integration of GPS, sensors along with software systems can be effectively used to provide safety as well as huge income to the Indian Railway
