Description

Technical Field

[0001] The present application relates to the field of cloud services, and more particularly to a system and method for transmitting binary files to a cloud server. Background Art

[0002] As an advanced network technology, server virtualization is gradually becoming a key driving force for power automation computer systems. By abstracting physical server resources into logical resources, flexible allocation and efficient utilization of computing resources are achieved, greatly improving the flexibility and response speed of power automation computer systems.

[0003] Thanks to virtualization technology, power companies have built enterprise cloud services, and business systems are all running on cloud servers. Virtualization technology enables cloud services to manage and allocate resources more efficiently, reducing operating costs, while enhancing the security and isolation of cloud services. It also supports centralized data management and backup and recovery operations, improving data security and reliability. Virtualization technology can be used to ensure that services comply with industry regulations and standards.

[0004] Cloud terminals are used in conjunction with server virtualization technology. Cloud terminals, also known as cloud desktops or desktop virtualization terminals, are a new type of terminal equipment based on cloud computing technology. They connect to remote servers through specific communication protocols (such as VDI, RDS, SPICE and other cloud desktop technology communication protocols), and use the server's powerful computing and storage capabilities to provide terminal users with operating system, application and data storage services.

[0005] However, the use of cloud terminals brings some problems to system debugging. For example, after the power automation system is deployed using cloud terminals in conjunction with cloud servers, the cloud servers can be centrally managed and are generally located in the main computer room of the power company. The interactive terminals of the business system are deployed in the office environment using cloud terminals and connected through the network. The two locations are not necessarily located in the same building group and may even be very far apart. At the same time, in order to make maintenance and management easier, most of the cloud terminals used only provide basic hardware interfaces, namely keyboards, mice, monitors, and network interfaces, and are connected to cloud servers through specific communication protocols. The user's input commands through the keyboard and mouse are transmitted to the cloud server for processing, and the processing results are displayed on the cloud terminal in the form of a graphical interface.

[0006] Since most cloud terminals used in power automation systems have removed the USB disk function for transferring files, there is a lack of means for file transfer. Especially when deploying new application systems and performing system function maintenance and debugging, when a large number of files need to be updated, if the files can only be uploaded to the server by carrying them to the main computer room, the system debugging time will be extended and the work progress requirements cannot be met. Summary of the invention

[0020] For example, the Linux system uses the following shortcut key sequence "Ctrl+Alt+T" to open the cloud terminal window; the Windows system uses the following shortcut key sequence "Win logo key + R, cmd.exe, Enter key" to open the cloud terminal window; if you need to improve adaptability, you can also design this sequence into a software configurable item.

[0021] For ease of description, the descriptions of key sending in the steps are simplified. For example, the key signal actually sent by Ctrl+Alt+T should be: Ctrl↓ Alt↓ T↓ [delay] T↑ Alt↑ Ctrl↑, ↓ indicates the key pressed signal, and ↑ indicates the key released signal.

[0022] S102, the main control device reads the binary file selected by the user to be sent through the main control software, and converts the content of the binary file, that is, the original binary data, into a set of escape character sequences represented in hexadecimal: H1 H2H3 ...H n , n is a natural number greater than or equal to 1, that is, each H n The escape character sequence corresponding to the original binary data byte; Hexadecimal is a format that can be recognized by the Linux system echo command. For example, the three binary bytes: 01h, 02h, A3h are converted into 9 hexadecimal characters: 'x' '0' '1' 'x' '0' '2' 'x' 'a' '3'.

[0023] S103, the main control device creates a hexadecimal file on the cloud terminal side through the main control software via a signal converter; Specifically, use the following shortcut key sequence "echo -n -e ''> "F BIN ” <cr>",in <cr>Indicates the Enter key, echo is the command to generate files in the Linux system, F BIN is the hexadecimal file name.

[0024] S104, the main control device sends the escape character sequence represented in hexadecimal to the hexadecimal file on the cloud terminal side in segments through the main control software via the signal converter cyclically until all the characters are sent; then execute S109.

[0025] Specifically, use the following shortcut key sequence "echo -n -e 'H p+1 H p+2 H p+3 …H p+x '>> "F BIN ” <cr>”, where H p+1 This is the first escape character sequence sent this time, H p The last escape character sequence sent.

[0026] Specifically, the escape character sequence represented in hexadecimal is divided into multiple segments according to appropriate lengths, for example, each 64-byte escape character sequence is regarded as one segment.

[0027] S105. The main control device reads the binary file selected by the user to be sent through the main control software, and converts the content of the binary file, that is, the original binary data, into a set of escape character sequences represented by 3 decimal digits: D1D2D3…D n , n is a natural number greater than or equal to 1, that is, each D n The escape character sequence corresponding to the original binary data byte; Decimal is the format that the Windows copy con command can recognize. For example, the three binary bytes: 01h, 02h, A3h are converted into a decimal sequence of 9 characters: '0' '0' '1' '0' '0' '2' '1' '6' '3'.

[0030] For example, to send the binary byte 01h, you need to send the following sequence of key signals: Alt↓0↓0↑0↓0↑1↓1↑Alt↑ S108, the main control device sends a file end instruction: Ctrl+Z, i.e., the copy con command of the Windows system to close the file, to the cloud terminal via the main control software via the signal converter, and then executes S109.

[0031] S109, the main control device sends a command "exit" to close the cloud terminal window to the cloud terminal through the main control software via the signal converter. <cr>", the file transfer is completed; the cloud terminal sends the received file to the cloud server.
