Fig. 1 is a flowchart of a method for remotely accessing an electric power secondary system across applications in accordance with an embodiment of the present invention. As shown in fig. 1, a method 100 for remotely accessing a power secondary system across applications in accordance with the present invention begins at step 101.
In step 101, virtualizing an electric power secondary system application program of an application virtualization service terminal through an application virtualization technology;
in step 102, the application delivery unit installs a program for delivering the application program to the application virtualization service terminal on the electric power secondary system for delivering the application program to the outside, and configures the electric power secondary system application program to be registered and issued and performs access authority control on a remote access user in the program for delivering the application program to the application virtualization service terminal;
in step 103, the application virtualization client acquires the human-computer interaction logic of the remote access user, generates direct virtual application information, and transmits the direct virtual application information to the application virtualization server through the application delivery unit to complete virtualization delivery;
in step 104, after completing the virtualization delivery, the application virtualization service terminal starts and executes the power secondary system application program that has completed the virtualization delivery, and transmits the execution result to the application virtualization client through the application delivery unit.
Preferably, before the virtualizing the application program of the power secondary system of the application virtualization service terminal by using the virtualization technology, the method further includes installing the application program of the power secondary system on an operating system of the application virtualization service terminal. The power secondary system application program is deployed on an application virtualization server operating system, so that application virtualization technologies of different operating systems are different, for example, application virtualization software of a Windows operating system and a Linux operating system is different greatly, and the application virtualization program needs to be transplanted across platforms.
Preferably, configuring the power secondary system application program to be registered and released in the program delivering the application program to the application virtualization service terminal comprises configuring resources, safety characteristics and functions for the power secondary system application program to be registered and released and recording application attributes of the application program.
Preferably, the recording of the application attribute of the application program includes recording system information, a server address, system user information, service user information, a program path, a network resource condition and an application exclusivity of the application program.
Preferably, the controlling the access right of the remote access user by the application delivery unit comprises:
the application delivery unit performs unified authorization on all remote access users;
the authorization granularity is consistent with user access rights of users in the power secondary system.
Preferably, the direct virtual application information is transmitted to the application virtualization service end through the application delivery unit to complete the virtualization delivery, the application virtualization service end starts and executes the power secondary system application program which completes the virtualization delivery after completing the virtualization delivery, and the execution result is transmitted to the application virtualization client end through the application delivery unit, and the high-speed transmission of data is realized by adopting the deduplication and compression technology.
The application virtualization remote transmission mechanism transmits the content displayed by the application program to a remote user, and simultaneously transmits the mouse and keyboard operation logic of the remote user to the application program. The method aims to realize no frame loss and instant response, no skip or discard of any image detail displayed by an application program, smooth transmission of a dynamic image displayed by the application program, instant transmission of operation information of a remote user to the application program and no influence of transmission of a large amount of burst image detail. In order to improve the transmission efficiency and reduce the network traffic in the transmission process, an efficient deduplication and compression mechanism must be provided.
In this embodiment, in the processing operation before data transmission, the elements such as the text, dialog box, button, curve, bar chart, etc. displayed by the application program are all converted into binary images. Because the transmission image occupies more network resources, the repeated part in the image needs to be removed and the image needs to be compressed, and the data volume is reduced. And converting the graph into an RGB pixel matrix in the memory in the image processing, and after the application program interface is refreshed, capturing and refreshing part of the graph and converting the graph into the memory matrix. The repeated portions are removed and only the changed portions are stored in the matrix by comparison with the pre-refresh matrix.
Human-computer interaction logic such as a mouse and a keyboard is also important content in the transmission process, and the transmission and processing priority is higher due to the real-time requirement. After the application virtualization client receives the keyboard and mouse equipment response message, the transmission mechanism preferentially sends the event data. At the application virtualization server side, the transmission mechanism preferentially receives the event data, and immediately replays the event data at the server side to generate corresponding mouse and keyboard operations. The mechanism can ensure the real-time operation and obtain the high-quality user experience.
Fig. 2 is a block diagram for remotely accessing an electric power secondary system across applications according to an embodiment of the present invention. As shown in fig. 2, a system 200 for remotely accessing an electric power secondary system across applications according to the present invention includes:
the application virtualization server 201 is used for virtualizing the power secondary system application installed thereon by using an application virtualization technology, starting and executing the power secondary system application which has completed the virtualization delivery after completing the virtualization delivery of the direct virtual application information generated by the application virtual client through the application delivery unit, and transmitting the execution result to the application virtualization client through the application delivery unit;
an application delivery unit 202, configured to install a program for delivering an application to an application virtualization service terminal on an electric power secondary system that externally issues the application, and to configure an electric power secondary system application to be registered and issued among the program for delivering the application to the application virtualization service terminal, and to perform access authority control for a remote access user;
the application virtualization client 203 is used for acquiring the human-computer interaction logic of the remote access user, generating direct virtual application information, transmitting the direct virtual application information to the application virtualization service terminal through the application delivery unit to complete virtualization delivery, and receiving the execution result of the power secondary system application program which is transmitted by the application virtualization service terminal through the application delivery unit and completes virtualization delivery.
In this embodiment, the application delivery unit is a core of application virtualization and remote control, and is an important module for registering and issuing the power secondary system program of the application virtualization server and performing rights management on a remote user. If a subsystem of the power secondary system needs to be remotely regulated, the system must be registered and issued in the application delivery unit, and an authorized user can access the system. Registration and issuance of the power secondary system is different from conventional application delivery, and has the following characteristics:
1) client/server architecture: the power secondary system adopts a client/server architecture, and various application programs of the system are respectively operated in different servers;
2) resource management and control: authorizing and managing resources in a power secondary system resource pool, controlling resources required by an application program, how to distribute the resources and which functions are allowed to run;
3) safety management and control: the power secondary system is divided into a production area and a management area, wherein the production area is divided into a safety first area and a safety second area, and the main difference is data importance and real-time property. In the application program virtualization delivery process, the original safety system of the power secondary system must be kept, and the safety protection requirement is met.
The application delivery unit is required to install a program for delivering the application program to the application virtualization service terminal on the power secondary system which externally releases the application, then configure the application program which needs to be registered and released in the program for delivering the application program to the application virtualization service terminal, and configure necessary resources, security features, functional rights and the like for the application program to ensure that the application program is available in the power secondary system. When the application delivery unit registers the application program configured in the program for delivering the application program to the application virtualization server, the system information, the server address, the system user information, the service user information, the program path, the network resource condition, the application exclusivity and other application attributes of the application program are recorded, so that the application program can be addressable and positioned when being accessed by a remote user.
The application delivery unit needs to manage the remote regulation and control user. Since the application delivery unit can perform cross-professional access to a plurality of subsystems of the power secondary system, and can perform monitoring control on the overall operation condition of the power grid from the whole to the details, strict user access authority limitation is required. The application delivery unit is used for carrying out unified authorization on the user, the authorization granularity is fused with the user authority of the application system, and unified safety management of the user authority is realized.
