A Survey Paper on Driverless Metro Train

Electronics and Telecommunication

As automation increases in train services, the main reason is to see how security can be increase. By using sensors, todays technologies and reconstruct the stations with walls on the platforms, the safety can increase for the effective. This project design a railway system consisting of a train, boom barriers and a station. The mechanical parts are made from scratch to get the system to work beneficially. The use of ARM as a micro controller where electrical components could be programmed, became the control of all subsystems. Ultrasonic- and IR sensors are used to detect if obstructions where located on the rails and to detect the oncoming train at the railway crossing. To increase safety, a wall was built on the platform with doors to prevent people from tracing the tracks. The platform door open and close simultaneously with the door on the train. As a result, all subsystems worked well separately. When connecting them with each other, some problems occur. For example, door operations has not match up to 100 percent, which still considered approved. The major problem is that the train became too heavy for the motor to drive it properly. As there is no time to implement a larger motor, the solution to increase the voltage with two 9V batteries connected in series.
