[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] It should be noted that all actions of acquiring signals, information or data in the present disclosure are performed with authorization given by the owner of the corresponding device.

[0025] Before introducing the specific implementation methods of the present disclosure in detail, the application scenarios of the present disclosure are first explained. The present disclosure can be applied to the remote simulation training process of a power plant. In the prior art, in the power plant simulation training system, the image data transmission between the teacher-side device and the simulation machine is often directly transmitted across domains. Due to the limitation of network bandwidth, the transmission speed is low and the delay is serious. The existing transmission method not only affects the simulation training effect, but also may cause data security problems such as leakage of important information during the transmission process.

[0026] In order to solve the above technical problems, the present disclosure provides an image processing system for power plant simulation training, including a sending end device, a gateway device and a receiving end device, the sending end device is connected to the receiving end device through the gateway device, the sending end includes a teacher end device, and the receiving end includes a simulator; or the sending end includes a simulator, and the receiving end includes a teacher end device; the sending end device is used to send image data to the gateway device; the gateway device is used to receive the image data sent by the sending end device, and after performing data processing such as image data compression, image data encoding and image data encryption on the image data, obtain a pixel stream, and send the pixel stream to the receiving end device. The image processing system can reduce the amount of data transmission by adding a gateway device between the sending end and the receiving end device, and performing data compression and other processing before transmission, thereby increasing the transmission speed and reducing the reception delay phenomenon at the receiving end.

[0027] The specific implementation of the present disclosure will be described in detail below with reference to the specific drawings.

[0028] Figure 1 is a block diagram of an image processing system for power plant simulation training according to an exemplary embodiment. Figure 1 As shown, the system 100 includes a sending end device 110, a gateway device 120 and a receiving end device 130, wherein the sending end device 110 is connected to the receiving end device 130 via the gateway device 120. The sending end includes a teacher end device, and the receiving end includes a simulation machine; or the sending end includes a simulation machine, and the receiving end includes a teacher end device.

[0029] The sending end device 110 is used to send image data to the gateway device.

[0030] By way of example, the image data may include a desktop image on a display device of a sending device. For example, the desktop image on a display device of a teacher's device may be a device operation demonstration image, and the desktop image on a display device of a simulator may be an image of the actual operation process of a technician participating in the training.

[0031] The gateway device 120 is used to receive the image data sent by the sending device, perform a first data processing on the image data, obtain a pixel stream, and send the pixel stream to the receiving device; the first data processing includes at least one of image data compression, image data encoding and image data encryption.

[0032] Among them, the gateway device can be a hardware device including components such as a processor, memory and network interface, which is used to realize data transmission between different networks; the data in the pixel stream is obtained after the first image data is compressed, encoded and encrypted, and pixel stream transmission can increase transmission speed and reduce delay.

[0033] Optionally, the sending end includes a teacher end device, the receiving end includes a simulation machine, the sending end device is used to determine at least one receiving end device and send the first image data to the gateway device, the first image data includes address information of the receiving end device; The gateway device is used to receive the first image data sent by the sending end device, perform second data processing on the first image data to obtain a first pixel stream, and send the first pixel stream to the receiving end device according to the address information; The receiving device is used to receive the first pixel stream sent by the gateway device, and perform second data processing corresponding to the first data processing on the first pixel stream to display the first image on the display device of the receiving device; wherein the second data processing includes at least one of image data decryption, image data decompression and image data decoding.

[0034] In a possible implementation, the sending end is a teacher device, and the receiving end is a simulation machine. Figure 2 is a block diagram of another image processing system for power plant simulation training according to an exemplary embodiment. Figure 2 As shown, the system 200 includes a teacher-end device 210 , a gateway device 220 and a plurality of simulation machines 230 , and the teacher-end device 210 is connected to the plurality of simulation machines 230 via the gateway device 220 .

[0035] For example, in a possible application scenario, the teacher-end device 210 needs to send the desktop image on the display device of the teacher-end device 210 to multiple simulation machines 230. The teacher-end device 210 is used to determine the five simulation machines 230 and send the desktop image data to the gateway device 220. It should be noted that the desktop image data includes the address information of each simulation machine, and the address information is used by the gateway device 220 to determine the corresponding receiving device. Among them, the address information can be an IP address, a MAC address, a network address or a device identifier, etc., which is not limited by the present disclosure. The gateway device 220 is used to receive the desktop image data sent by the teacher-end device, and after data processing of the desktop image data, obtain a pixel stream, and send the pixel stream to the corresponding simulation machine according to the address information.

[0036] After receiving the pixel stream sent by the gateway device 220, the simulator 230 performs data processing on the pixel stream to display the desktop image on the display device of the teacher's terminal device on the display device of the simulator. The data processing corresponds to the data processing performed by the gateway device 220, for example, the gateway device 220 performs image data compression, and the simulator 230 performs image data decompression after receiving the data; the gateway device 220 performs image data encoding, and the simulator 230 performs image data decoding after receiving the data; the gateway device 220 performs image data encryption, and the simulator 230 performs image data decryption after receiving the data.

[0037] Optionally, the gateway device performing image data compression may include: Redundant data in the image data is determined, and the redundant data in the image data is removed by an image compression algorithm to compress the image data.

[0038] For example, removing redundant data in the image data may be removing redundancy between pixels. For example, in a certain area of ​​the image, the color difference between adjacent pixels is very small, so there is no need to independently retain the color value of each pixel. It may also be removing statistical redundancy. For features that appear frequently in the image data (such as certain colors or brightness values ​​that appear repeatedly in the image), compression can be performed using statistical methods.

[0039] Optionally, the gateway device may encode the image data by: The encoding format and encoding parameters are determined according to the network transmission environment, and the image data is encoded according to the encoding format and encoding parameters.

[0040] For example, the adapted encoding format and encoding parameters are determined according to the network bandwidth, wherein the image encoding format may include JPEG (Joint Photographic Experts Group), PNG (Portable Network Graphics), GIF (Graphics Interchange Format) and SVG (Scalable Vector Graphics) and other formats, and the encoding parameters may include parameters such as image resolution, color depth, compression level and transparency.

[0041] It can be understood that the gateway device can also adjust the image encoding parameters according to the display parameters of the display device, including: obtaining the display parameters of the display device of the receiving device, and performing encoding preprocessing on the image data according to the display parameters, wherein the encoding preprocessing includes adjusting the image encoding parameters, including parameters such as image resolution, color depth and transparency.

[0043] In another possible implementation, the sending end is a simulation machine, and the receiving end is a teacher end device. Figure 3 is a block diagram of another image processing system for power plant simulation training according to an exemplary embodiment. Figure 3 As shown, the system 300 includes a simulation machine 310 , a gateway device 320 and a teacher-end device 330 , and the simulation machine 310 is connected to the teacher-end device 330 via the gateway device 320 .

[0044] For example, in another possible application scenario, the simulation machine 310 needs to send the desktop image on the display device of the simulation machine to the teacher-side device 330. The simulation machine 310 can send a request message to the teacher-side device 330 to confirm whether the teacher-side device accepts the image sending request. Upon receiving the confirmation message sent by the receiving end 330, the simulation machine 310 sends the simulation machine desktop image data to the gateway device 320.

[0045] After receiving the simulation machine desktop image data sent by the simulation machine 310 , the gateway device 320 processes the image data to obtain a pixel stream, and sends the pixel stream to the teacher-end device 330 .

[0046] The teacher terminal device 330, after receiving the pixel stream sent by the gateway device 320, performs data processing on the pixel stream to display the simulation machine desktop image on the display device of the teacher terminal device. The data processing corresponds to the data processing performed by the gateway device 320, which will not be repeated here.

[0049] In step S402, the image data is processed to obtain a pixel stream; the data processing includes at least one of image data compression, image data encoding and image data encryption.

[0050] For example, when the data processing is image data compression, performing data processing on the image data may include: determining redundant data in the image data, and removing the redundant data in the image data by an image compression algorithm to compress the image data.
