Warning System for Unmanned Railway Crossing -IIT Kanpur new Innovative system

Warning System for Unmanned Railway Crossing -IIT Kanpur new Innovative system

Engineers at IIT Kanpur have developed a very useful warning system that can prevent accidents at unmanned level crossings, thereby saving many lives.

The technology, named Radio Frequency and Wireless Based Warning System, will produce a loud sound to alert people to remain off the tracks, and to inform the driver that a crossing is approaching.

If everything goes well and the trials are successful, the device will be put to use. Currently, trials are being conducted between Unnao and Sonik railway stations (crossing number 29C) and Lucknow-Sultanpur section (crossing number 189C). Following this, IIT Kanpur will hand over the technology to Research Designs and Standards Organization (RDSO) on Dec. 16. RDDO is a research and development organization under the Ministry of Railways and it functions as a technical adviser and consultant with regards to design and standardisation of railway equipment and issues related to railway construction, operation and maintenance. The organization had asked IIT Kanpur to develop such a system that would be efficient for two trains on two parallel tracks in one go.

However, the final system is more advanced than the initial expectation. If spread out on 16 parallel tracks, the warning system can handle 16 trains. The system with embedded GPS and RFID (radio frequency identification tag) will be installed in the train engine and at the unmanned railway crossing. When the train is 1,500 meters away from the crossing, the warning system will get activated and hooters will blow up informing the driver that a crossing is approaching.

“The same thing will happen when the train is just 800 meters away from the track. The flash hooters will stop buzzing when train crosses 50 metre mark from the crossing,” BM Shukla, principal software engineer at IIT-K told The Times of India.

The system is foolproof as even if the GPS stops functions, RFID will ensure that the system never fails.

In case of multiple tracks, like two trains crossing each other, the system will continue to function normally. Hooters will buzz for both trains and will close after the later train clears the 50m mark. The trials have been successful until now.

Heavy to Heavy rain in Coastal Areas From Nov 15 to Nov 21.

 Heavy to Heavy rain in Coastal Areas From Nov 15 to Nov 21.

Rain pounds Tamil Nadu as depression looms large

Tamil Nadu continued to experience monsoon fury, with heavy rains pounding various parts of the State under the influence of a well-marked low pressure area over Bay of Bengal, as the death toll from rain-related incidents climbed to 59.

There seemed to be no respite from the downpour with many parts of Chennai coming under water even as the weatherman forecast more rains for the next 24 hours, beginning 0830 hrs.

The India Meteorological Department said in a bulletin on Sunday that the well-marked low pressure area over southwest Bay of Bengal adjoining Sri Lanka persisted and “it is likely to move west-northwestwards towards Tamil Nadu coast and would concentrate into a depression during next 24 hours.”

Under its influence, more rains were expected in the next 24 hours, the Regional Meteorological Department said.

Weather warning (valid upto 0830 hrs IST of Monday):

Day 1 (15th Nov.): Heavy to very heavy rain would occur at a few places over north Tamil Nadu. Heavy rain would occur at isolated places over south Tamil Nadu. Moderate fog would occur at isolated places over Meghalaya, Nagaland-Manipur-Mizoram-Tripura, Uttar Pradesh, Haryana, Chandigarh & Delhi and north Rajasthan.

Day 2 (16th Nov.): Heavy to very heavy rain would occur at a few places over Tamil Nadu & Puducherry and at isolated places over Rayalaseema. Heavy rain would occur at isolated places over couth coastal Andhra Pradesh, south Tamil Nadu and south interior Karnataka. Moderate fog would occur at isolated places over Meghalaya and Nagaland, Manipur, Mizoram-Tripura.

Day 3 (17th Nov.): Heavy to very heavy rain would occur at isolated places over coastal Andhra Pradesh and Rayalseema.

Heavy rain would occur at isolated places over north Tamil Nadu and south interior Karnataka.

Day 4 (18th Nov.): Heavy to very heavy rain would occur at isolated places over coastal Andhra Pradesh.

Day 5 (19th Nov.): Nil.
Weather Outlook for the subsequent 2 days (20th Nov. & 21st Nov. 2015): Rain/thundershowers would occur at many places over Tamil Nadu, coastal Andhra Pradesh, Rayalseema and Kerala and would increase considerably over rest peninsular India. Minimum temperature would fall by 2-3 degrees C over northwest and adjoining central India.

Vizag based TV Mechanic develops Early Warning System for Unmanned Level Crossings

Vizag based TV Mechanic develops Early Warning System for Unmanned Level Crossings

Centre has to allot dedicated Radio Frequency for his Technology, –the technician says..

Visakhapatnam (VSKP): Here is a television technician, who has developed an early warning system for unmanned railway level crossings.

S.Senguttuvan, from Tamil Nadu, settled in Visakhapatnam, was moved by the accident in which over 26 school students travelling in a bus were mowed down by a train at an unmanned level crossing in Masaipet village of Medak district in Telangana on July 24.

He has developed an early warning system that works on radio frequency. Explaining the project he said, “There are two different types of warning systems. One that works on GPS technology and the other is a wired signal system.”
