Train collision avoidance system by using RFID

Railways are the convenient, reasonable and popular node of transport in almost all major cities of not only in India but also all over the World. Railways are the most widely used and comfortable nodes of transportation system. Now a day's in India most of the train accidents are occurs due to the human errors. It is very difficult to avoid to such train accidents because of the speed of train is very high and it requires some time to control it. In this paper the effective solution is present to avoid the train accidents by using Radio Frequency Identification (RFID). The primary goal of proposed system is to identify possible train collision ahead of time and to send the report to the main control room or driver before collision happens. Currently there is no solution to avoid train collision. Indian Railways have implemented solution based on ACD (Anti-Collision Device) system. Each locomotive is equipped with an automated surveillance system. The train tracks in railway network are divided into different frames and each segment has 10 km distance and given with distinct track numbers which are read by surveillance system inside the locomotive. Therefore the track id is needed to be given at 10 km distance on the train track. This track number will be shared with the base station by using Radio Frequency Communication system. The paper proposes specific way of numbering the train tracks in frames. If two trains are travelling on the same track then system sends SMS through GSM network to the authorized person to take appropriate action. In areas where GSM network is poor then also the system avoid collision by using RF Module. Wherever at crossing LDR sensor and microcontroller unit take appropriate action if obstacle can be observed.
