Step S200: Determine the file name of the data to be diagnosed according to the data directory item information, and determine whether all the file names are unique, if not, determine that the data to be diagnosed is wrong;

According to the data directory item information in the received diagnostic information, the file name of the data to be diagnosed can be determined. After the file name of the data to be diagnosed is determined, it can be judged whether these file names are unique. If it is determined that not all file names are unique, it can be determined The data to be diagnosed is incorrect.

Step S210: Determine whether the data to be diagnosed is abnormally changed according to the data session control information, and if so, determine that the data to be diagnosed is wrong;

According to the data session control information in the received diagnostic information, it can be determined whether abnormal changes have occurred in the data to be diagnosed, such as abnormally adding data, sending data loss, and abnormal data replacement. If it is determined that abnormal changes have occurred, it indicates that the pending The diagnostic data is incorrect.

Step S220: Determine the index number of the data to be diagnosed according to the node information of the data, and determine whether all the index numbers are unique, if not, determine that the data to be diagnosed is wrong.

According to the node information in the received diagnostic information, the index numbers of the data to be diagnosed can be determined. After determining the index numbers of the data to be diagnosed, it can be judged whether these index numbers are unique. If it is determined that not all index numbers are unique, it can be determined that the The diagnostic data is incorrect.

Among them, it should be noted that there is no logical sequence relationship among steps S200, S210 and S220, regardless of the execution order of steps S200, S210 and S220, and whether or not steps S200, S210 and S220 are executed at the same time. In step S220, as long as step S200, step S210 and step S220 are completed, the process of judging whether the data to be diagnosed is incorrect can be completed.
