In order to quickly identify the information of the arrival train and the departure train, the train number is often marked on the railway freight car to distinguish different railway freight cars. The train number is equivalent to the identity number of the railway freight car. By identifying the train number, the main information of the current railway freight car can be quickly known. However, due to the different loading of railway freight cars and the differences in the travel paths, the train number information of railway freight cars will be blocked or missing due to cargo pollution, driving stains, etc. after a period of driving, affecting the normal identification of the train number. In addition, the stop time of some port stations is very short, and it is impossible to clean and complete the missing or blocked train numbers in time. This makes it difficult for railway freight cars with blocked or missing train numbers to be identified by the existing train number recognition system or misidentification occurs, and the missing information is recognized as complete information.
