specifically, since only one external USB interface exists in each industrial control server, and in order to prevent errors in the data transmission process, the number of the industrial control servers and the target U disk is smaller than or equal to the number of the industrial control servers at the same time, namely m is smaller than or equal to n.
Further, the importance level corresponding to the industrial control server may be understood as a priority level corresponding to the industrial control server, where the higher the importance level of the industrial control server, the more important the industrial control server is proved.
S200, according to Z, acquiring a first target detection priority list JY= (JY) corresponding to the target USB flash disk 1 ，JY 2 ，……，JY j ，……，JY m ) The method comprises the steps of carrying out a first treatment on the surface of the Wherein JY i For the first target detection priority corresponding to the jth target USB flash disk, JY j Meets the following conditions:
；
specifically, if the database further includes an ID list of the key usb disk, a first target detection priority corresponding to the target usb disk is processed in a first manner; the key USB flash disk is a USB flash disk which needs an industrial control server to write data;

S400, according to TY, acquiring a detection sequence list ZU= (ZU) 1 ，ZU 2 ，……，ZU j ，……，ZU m ) The method comprises the steps of carrying out a first treatment on the surface of the Wherein ZU j Is TY j And the USB flash disk identifier of the corresponding target USB flash disk.
Specifically, the usb disk identifier is a unique identifier of the target usb disk, and the usb disk identifiers corresponding to any two target usb disks are different.
By considering the importance of the industrial control server, the data quantity of the file to be read and other factors, the detection priority is allocated to the U disk, so that the detection sequence is more reasonable, and the difference of the data quantity among different U disks and the importance of the industrial control server is adapted. The target USB flash disk which is detected firstly can be preferentially accessed to the corresponding server, and the shorter the target file to be read corresponding to the target USB flash disk is, the shorter the detection time is, so that in order to enable the industrial control server with high importance to be connected with the corresponding target USB flash disk more quickly, the priority processing of the short detection time of the target USB flash disk is considered, and the target USB flash disk can be accessed to the industrial control server more quickly, therefore, the target USB flash disk with smaller first target detection priority should be preferentially detected, and the detection efficiency is effectively improved. The detection priority of the USB flash disk is automatically calculated, errors of manual adjustment and assignment are reduced, and error rate is reduced.

The target USB flash disk which is detected firstly can be preferentially accessed to the corresponding server, and the shorter the target file to be read corresponding to the target USB flash disk is, the shorter the detection time is, so that in order to enable the industrial control server with high importance to be connected with the corresponding target USB flash disk more quickly, the priority processing of the short detection time of the target USB flash disk is considered, and the target USB flash disk can be accessed to the industrial control server more quickly, and therefore, the target USB flash disk with higher read-write priority of the first industrial control server should be preferentially detected, and the detection efficiency is effectively improved. And the read-write sequence priority of the industrial control server is automatically calculated, errors of manual adjustment and assignment are reduced, and error rate is reduced. Through realizing more intelligent, automatic USB flash disk detection order confirm, promote electric power system's automation level.
