Abstract -Objective of this paper is to provide safety of people and reduce train accidents taking place due to manual handling of the gates at railway crossing and also irresponsible behavior of the people. It includes many precautions and safety measures. Accident on railway crossing covers large percentage in train accidents. It also looks after the accident detection and takes actions related to that. It highly reduces time for which people have to wait at the railway crossing and wait for the signal to go green. Since the whole process is automatic human error is prevented .The whole process works on microcontroller based control. Here we have used AVR ATMEGA 16 MICROCONTROLLER. Key Words: GSM Module, AVR ATMEGA 16, GPS Module, Image processor.
1.INTRODUCTION Accident that is Collision of trains with automobiles, at railway crossing covers large percentage of train accidents. Accident causes loss of life and property. Train delay results in economical losses as well affects smooth functioning of train schedule. Accidents at railway crossing are mainly due to personal mistake that is irresponsibility of human being rather than train’s mistakes. Accident at railway crossing leads to increased number of deaths, despite several measures taken by the authorities, the railway crossing are the bigger killers, although trespassing into railway track is punishable offence but then also no one cares. It has become a human habit; one can wait for long in cinemas, restaurants etc. but can’t wait for crossing to be clear. Before going deep into the matter, we all must be well aware about the basic meaning of the term” level crossing”. So, what is railway crossing?. railway crossing level is an intersection where a railway tracks or lines crosses a road or a highway at same level, this is called railway crossing. And the most important problem that is very difficult to minimize is the careless behavior of the passengers to cross the railway crossing even if the gate is closed and that’s how the accidents takes place.
1.1.INTELLIGENT RAILWAY CROSSING SYSTEM Most of the researchers have worked upon Railway crossing, some have tried to reduce the manual operation by designing railway crossing as total automatic opening and closing of gates and some have made intelligent railway crossing using load sensors etc. But still better technology is needed to minimize the accident. Here, this journal consists interfacing of automatic railway crossing with new technologies and trying to present something ahead of previous researches. It has been prepared keeping in mind all possible measures for safety of the people. Before going into detail lets have look upon the system setup.
2. ULTRASONIC SENSOR Ultrasonic is a device that detect as well as measures the distance of an object from sensor using sound waves. It has four pins as shown in fig 1 1.VCC, 2.Trigger, 3.ground 4. echo. Using Trigger Ultrasonic sensor transmits the Ultrasonic sound, which is a high frequency sound whose audible range is greater than the human hearing. It measures distance by transmitting Ultrasonic sound and then wait for listening the sound wave using echo pin. As the sound travels in air at a speed of 344m/s. So distance covered, Distance covered = (speed of sound*time taken)/2.
