Problems solved by technology

And in the product testing stage, you can also test, upgrade, and download data through the SD card. Although the SD card is convenient to operate, after the test is completed, because the device automatically scans and monitors the SD card interface and performs operations, so It is easy to cause a wrong upgrade or wrong download operation through the SD card interface in the application, which eventually leads to the failure of the device to work normally.

Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. In this embodiment, the method for locking and unlocking the SD card mainly includes the following steps:

[0012] First, add a command to manage the SD card interface in the configuration file of the industrial device.

[0013] Secondly, input the configuration file to the industrial equipment through the SD card,

[0014] Furthermore, the industrial equipment reads corresponding instructions to realize the locking of the SD card interface.

[0015] In the application, it may be necessary to re-upgrade the device or download data. It is necessary to unlock the locked SD card interface. There are many ways to unlock it. The first method is the same as locking the SD card interface. The configuration file reads the command to realize the unlocking of the SD card. The second method is to unlock through the password when setting the com...

Abstract

The invention relates to a management method of an SD card interface which an industrial device comes with, and aims to solve the technical problem of providing the method of managing the SD card device interface to prevent erroneous operation in application and improve the security of SD card data. The method of managing the SD card interface mainly includes: adding, in a configuration file of the industrial device, an instruction of managing the SD card interface; inputting the configuration file into the industrial device through an SD card; and reading the corresponding instruction by the industrial device to realize locking or unlocking of the SD card interface.

Description

technical field [0001] The invention relates to a mobile storage device, in particular to a management method for an SD card interface of an industrial device. Background technique [0002] With the development of science and technology, SD card, as the main mobile storage device, is widely used not only in consumer digital devices, but also in industrial fields. Many industrial devices need to use SD cards due to their own limitations. As a bridge to connect to the outside world, a lot of industrial equipment has its own SD card interface, through which SD card interface can be used for testing, software upgrade, and data download and export. And in the product testing stage, you can also test, upgrade, and download data through the SD card. Although the SD card is convenient to operate, after the test is completed, because the device automatically scans and monitors the SD card interface and performs operations, so It is easy to cause a wrong upgrade or wrong download ope...
