Background

The locomotive is a self-propelled vehicle which pulls or pushes a railway vehicle to run and does not load business load per se, and is commonly called a locomotive. The locomotive is the least energy consuming land vehicle, as calculated by the amount of fuel consumed per ton of kilometer transported. Locomotives are typically driven by power machines such as steam engines, diesel engines, gas turbines, traction motors, and the like, either directly or through a transmission. The power machine makes the driving wheel of the locomotive generate moment, and the road gives the driving wheel with reaction force with equal magnitude and opposite direction. The sum of the individual wheel reaction forces is referred to as the locomotive tractive effort. This traction force is a tangential external force generated by the forces acting on the moving wheel rim and is also called wheel rim traction force. When the locomotive or the train runs, wheels roll on the track in a pressing mode, and the wheels and the track are elastic bodies, so that elastic deformation can be generated, and true round and straight lines or planes cannot be formed. The speed of each vehicle in motion is not completely consistent, the action of the coupler buffer device is also inconsistent, unbalanced force is generated in the motion of the locomotive vehicles, different braking force is generated during braking, the train passes through a curve line and other complex factors, and the influence of external air turbulence can cause the locomotive or the train to generate vertical, transverse and longitudinal vibration.

However, the door lock of the conventional locomotive is a door lock adopting a purely mechanical manual switch, and whether to unlock or close the door lock needs to be manually determined and needs to be manually operated, so that manual errors are easily caused, the lock cannot be closed in time due to forgetting to close the door lock, non-railway system personnel pedal the locomotive in a private way, and certain potential safety hazards are caused to the locomotive application safety.
