The railway transportation is the safest and most convenient means of transportation. However, consistent and stable operations of this large and complicated system actually rely on numerous, accurate and reliable controllers. When the train comes in and leaves the station, the controller will trigger the switch for accurate operation to ensure that the train heads to the right track. When the train comes in the station and stops in position, the controller will control the opening/closing of train doors and platform gates to prevent passengers from falling accidentally into the track; when the train approaches the railroad crossing, the controller will trigger the barrier to come down and continuously monitors the emergency pushbutton and the conditions of the peripheral sensors to ensure safety of the train and the traffic flow. For the interior of the train, the controller will monitor air conditioning, fire and the toilet vacuum flushing system, ensuring that each function of the train works normally.
