Smart vibration sensor to check rail accidents
Two researchers Alka Dubey and Ashish Verma from Sagar University have claimed to have developed a smart vibration sensor with wireless communication to check the required speed on the rail track. This innovation would reduce accidents of trains.
A SMART vibration sensor with wireless communication for recording and analysing train vibration has been developed in the country.
 
Alka Dubey and Ashish Verma of Sagar University brought this innovation to light, while presenting their paper at the fourth international Wireless Communication Sensor Networks concluded at Indian Institute of Information Technology-Allahabad (IIIT-A) on Monday (Dec 29).
 
Dubey said that high speed trains are one of the most impressive developments of the recent years having brought a new degree of comfort for travelers. These trains posed serious accidents because of the high level of vibration, which are generated. Therefore to make the train speed smoother, a smart vibration sensor is developed. It is a self sensation device equipped with recording and wireless communication interface.
 
“One programmed microcontroller 89C52 is used, which records vibration of trains with real time into memory. There are certain limits of vibrations, which are acceptable by the railway track. Beyond this limit the tracks may be damaged, resulting in major causality,” she said.
 
“The sensor with microcontroller interface has been designed, developed and tested at Sagar railway station for reliability of electronics. The sensor can be accessed wirelessly from a personal computer or laptop,” she informed.
 
This sensor is useful for recording the vibrations of trains with respect to date and time by which investigation team can get the appropriate reason of accident due to vibration. Smart vibration sensor does not require wired communication. It can be communicated with PC or laptop’s using wireless communication.
 
Railway is an enormous medium of transportation in India. The rate of rail accidents is high. To decrease the rate of accidents it is important to know the appropriate reason(s) of accidents. Vibration induced by train is an important data for accident investigation team. There are certain limits of vibration from 0 to 100 Hz, which is acceptable for proper train movement. Beyond this limit accidents might occur.
 
Speaking on the occasion, Prof M Radhakrishna said the conference had achieved another milestone this year by receiving quality research papers. Prof US Tiwari threw light on role of smart-dust sensors in coming years.
