Traveling derailment prevention device capable of dynamically monitoring rail state

Technical Field

The invention relates to the technical field of derailment prevention of traveling vehicles, in particular to a derailment prevention device for a traveling vehicle, which can dynamically monitor the state of a track.

Background

Railway tracks, referred to as rails, tracks, etc. The device is used on railways and cooperates with a switch to enable the train to walk without turning. The track is usually composed of two parallel rails. The rails are fixed on sleepers, and ballast is arranged below the sleepers. Rails made of steel can bear a greater weight than other materials. Sleepers, also known as crossties or sleepers, function to spread the weight of the rails separately and to keep the rails fixed, maintaining the gauge of the rails. Generally, the bottom of the track is gravel. The ballast, also known as ballast, ballast stone or ballast bed, provides elasticity and drainage function for the track. The rails can also be laid on concrete foundations (as is quite common on bridges) or even embedded in concrete.
