Method and system for judging the state of a heavy-load freight train

The invention relates to the technical field of train state detection, in particular to a method and a system for judging the state of a heavy-load freight train and a computer readable medium. The invention provides a method for judging the state of a heavy-load freight train. The method comprises the following steps: S1, acquiring state data of each pair of connected couplers in the train; and S2, according to the obtained state data of each pair of connected couplers in the train, judging to obtain a train state and outputting the train state. According to the method and system for judgingthe state of the heavy-load freight train and the computer readable medium, the state of a coupler is monitored in real time, the state of the train and the change trend of the state of the train canbe effectively detected and obtained, the method and the system can play an important role in stability control of the train, and a basis is provided for a train driver or an automatic driving systemto control the train. 本发明涉及
