Description
Technical Field
The present invention relates to the field of read control technologies, and in particular, to a method for controlling a usb flash disk read, an electronic device, and a storage medium.
Background
In the prior art, the USB flash disk is taken as a convenient data storage device, and is popular with users due to the characteristics of small size and portability. In many cases, data often needs to be transferred between different devices via a USB flash disk. For example, in the power industry, each substation server needs to acquire and update data in time, and a usb disk is often used as a tool for data carrying and transmission.
However, in the practical application process, there are some inherent problems in the conventional usb disk reading method. Firstly, data reading of a plurality of U disks is usually performed in a sequence from beginning to end, and only one U disk can be read at a time, so that the efficiency of data processing is greatly limited. If the reading mode cannot meet the requirement in an environment where a large amount of data needs to be read quickly, the reading mode clearly becomes a bottleneck of data processing efficiency. Second, there is a lack of effective security detection mechanisms. When an unverified USB flash disk is accessed to the system, potential risks such as viruses, malicious software and the like may be carried, which may bring about a certain safety hazard to the system. In addition, under the prior art, there is no effective mechanism to help identify and prioritize more important data reading tasks. For example, in a power system, some servers are responsible for critical facilities and some servers' data is not of great importance. For all connected USB flash drives, the data they may contain may be important to some parts of the system, while it may be less important to other parts. In this case, a mechanism is provided that can distinguish this importance and take it as the basis of processing priority, which can certainly improve the efficiency of updating the data of the whole system. Therefore, a new method for controlling the read of a usb disk with efficient data processing capability, while ensuring data security and optimizing data read priority is urgently needed.

Through the steps, (1) the reading efficiency of the data is improved, namely, in the prior art, the USB flash disk is usually read one by one, and the data cannot be read in parallel among a plurality of devices, so that the reading efficiency is lower. In the method, a plurality of USB flash discs can be simultaneously connected into a plurality of USB interfaces, and the connection of each USB flash disc to each transformer substation server can be independently controlled through the control module, so that the problem of low reading efficiency of a single USB flash disc is solved, and the data reading efficiency is improved.
