[0033] Figure 2 is a flow chart of a file management method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0034] Step S202, receiving power-off information sent by the touch screen;

[0035] In one application scenario of this case, the file management method is applied to a mobile terminal, server, computer terminal or similar computing device with a touch screen; taking the mobile terminal as an example, the execution subject of this case can be the MCU (full name: Microcontroller Unit) of the mobile terminal. When the industrial touch screen is ready to power off, the touch screen itself sends the power-off information to the MCU, so that the microcontroller unit is the execution subject to execute the file management method of this solution.

[0036] Step S204: Sending a backup instruction to the file manager associated with the touch screen based on the power-off information;

[0037] According to the example of the above application scenario, after receiving the power-off information, the MCU sends a backup instruction to the file management system of the touch screen; optionally, it also includes sending an encryption instruction to the file management system.

[0038] Step S206, storing the application file corresponding to the touch screen to the target folder according to the backup instruction;

[0039] Preferably, it also includes: sending an encryption instruction to the file manager associated with the touch screen based on the power-off information; changing the executable attribute information of the application file based on the encryption instruction; encrypting the changed application file using a triple data encryption algorithm; judging whether the encryption operation on the changed application file is successful; if the encryption is successful, setting the parent directory corresponding to the target folder to a hidden state and setting a verification mechanism to hide the target folder; otherwise, re-encrypting the changed application file using the triple data encryption algorithm.

[0040] Furthermore, after the encryption operation on the modified application file is successful, the running directory corresponding to the target folder is entered to close the running process in the running directory corresponding to the target folder and delete the running process; whether there is a file operation in the running directory of the target folder is detected; if there is a file operation in the running directory of the target folder, the running directory corresponding to the target folder is re-entered to close the running process in the running directory and delete it. In this embodiment, the existing program is pkilled, that is, the existing running process is pkilled to close the program operation and then the running process is deleted.

[0041] Preferably, the end and running directory environment of the existing program (ie, the program running directory) can be obtained by capturing and interpreting the message.

[0042] Preferably, in an example of this embodiment, the control objects are the touch screen program and the backup folder, and the folder where the touch screen program is located and the specified directory can be displayed by connecting to the touch screen.

[0043] In an optional example, after receiving the power-off information, the MCU sends backup instructions and instructions for encrypting the touch screen program to the touch screen file system (i.e., the above-mentioned file manager); further, in a specific folder directory (i.e., the above-mentioned target folder), the executable program in the running directory is copied to the folder directory, and the row attributes of the application file are changed, mainly changing its executable attributes, and the changed application is triple DES encrypted, and then the parent directory of the application file is set to a hidden state and a verification mechanism is set to increase confidentiality and security.

[0044] Step S208: When it is detected that there is no file operation in the running directory of the target folder, the power module associated with the touch screen is controlled to be powered off.

[0045] Furthermore, before the power module associated with the touch screen is controlled to be powered off, triple data encryption is performed on the running directory corresponding to the target folder.

[0046] Preferably, the above step S208 specifically includes: reducing the power supply voltage in the power module to zero. In this embodiment, the power module is notified to shut down the power in a step-by-step manner, thereby avoiding damage to files and components during the power-off process.

[0047] Preferably, the step-by-step power-off action is identifiable.

[0048] In another optional embodiment of the present case, the above method also includes: receiving a power-on instruction; sending a verification request to the touch screen based on the power-on instruction; when the verification is successful, unlocking the hidden state of the parent directory corresponding to the target folder; and copying the encrypted application file in the target folder to the running directory; decrypting the encrypted application file, and modifying the attribute information corresponding to the decrypted application file to run the decrypted application.

[0049] In this embodiment, when power is turned on, verification is first performed, and the encrypted folder is decrypted after passing the verification; wherein the verification action is identifiable.

[0050] The file management method provided by the embodiment of the present invention sends backup instructions and encryption instructions to the file manager associated with the touch screen after obtaining power-off information of the touch screen, thereby storing the application files corresponding to the touch screen in a specified target folder and encrypting the application files. When it is detected that there is no file operation in the running directory of the target folder, the power module associated with the touch screen is notified to cut off the power, thereby protecting the application files and important data files of the touch screen, thereby reducing the component wear and file loss of the touch screen, solving the technical problem of the related art that the touch screen cannot be effectively protected, reducing the cost of the touch screen and improving the usage efficiency.

[0051] The present invention will be further described below with reference to a working flow diagram of a specific embodiment:

[0052] Figure 3 FIG. 1 is a flow chart of a file management method applied to a touch screen according to a specific embodiment of the present invention. Figure 3 As shown, the following steps are included:

[0053] Step S301: The MCU recognizes that it is ready to power off.

[0054] Step S302: The MCU sends a backup and encryption instruction to the file system; after entering the file system, it enters a specific folder (i.e., the target folder mentioned above);

[0055] Step S303, based on the backup instruction, copy the program to a specific folder;

[0056] Step S304, changing the executable attribute information of the program;

[0057] Step S305, performing triple DES encryption on the program file with changed attributes;

[0058] Step S306, determine whether the encryption is successful; if the encryption fails, return to step S305;

[0059] Step S307: If the encryption is successful, the target folder is hidden;

[0060] Step S308, enter the running directory of the target folder;

[0061] Step S309, PKILL program and delete;

[0062] Step S310, determine whether there is a file operation; if yes, return to step S308; if not, go to step S311;

[0063] Step S311, perform triple DES encryption on the running directory;

[0064] Step S312: Slowly reduce the voltage until the power is cut off.

[0065] Furthermore, after a power outage, Figure 4 As shown, Figure 4 This is a touch screen power-on flow chart applied to a touch screen according to a specific embodiment of the present invention, specifically including:

[0066] Step S401, receiving a power-on instruction;

[0067] Step S402, sending a verification instruction;

[0068] Step S403, determine whether the verification is successful; if not, return to step S402 and resend the verification instruction; otherwise, execute step S404;

[0069] Step S404, unlocking the hidden directory;

[0070] Step S405, unlocking the running directory;

[0071] Step S406, copy the program to the running directory;

[0072] Step S407, modifying the permission attributes;

[0073] Step S408: Run, the touch screen starts normally.
