[0033] Hereinafter, preferred embodiments of the present invention will be described clearly and in detail with reference to the attached drawings so that a person skilled in the art can easily practice the present invention.
[0034] FIG. 1 is a drawing showing a system for transmitting a power plant status screen in real time according to one embodiment of the present invention.
[0035] The power plant status screen transmission system (100) illustrated in FIG. 1 has a central processing unit (120) that collects screen data and outputs it to an external device through a memory (130) and a communication module (140). In this process, a buffer (150) can serve as a temporary storage to reduce data stagnation.
[0036] The power plant status screen transmission system (100) illustrated in FIG. 1 is a system for transmitting a power plant status screen in real time and may include a power plant status screen (110), a central processing unit (120), a memory (130), and a communication module (140). Additionally, the power plant status screen transmission system (100) may further include a buffer (150). Additionally, the power plant status screen transmission system (100) may further include a screen capture and transmission interface (160).
[0037] The power plant status screen (110) can provide the operator (180) with real-time visualization of the operating status of complex equipment within the power plant or the operating status of various control systems.
[0038] The central processing unit (120) can pass collected screen data from point A (113) of the power plant status screen (110) corresponding to the time when the screen capture and transmission command is received, up to point B (116), which is the end point of the screen, without storing it in memory (130) when the operator (180) inputs a capture and transmission command for the power plant status screen as needed through the screen capture and transmission interface (160).
[0039] After that, the central processing unit (120) can collect screen data from point C (111) where the screen starts and store it in memory (130).
[0040] If there is a difference between the screen data and the data collected from point C (111) at the time the screen capture and transmission command is input, the central processing unit (120) can check the difference between the data and update the part of the data that differs with the latest screen data and store it in memory (130). That is, the screen data is compared by each pixel in block units, and only the blocks where a difference is confirmed can be updated.
[0041] The central processing unit (120) continuously monitors the state of the memory (130), and when the empty space of the memory (130) falls below a first threshold or the loaded data exceeds a second threshold, the data loaded in the memory (130) can be transmitted to the communication module (140). Here, the communication module (140) may be a chip, modem, hub, or a module capable of processing a printer protocol that handles the physical layer of transmission.
[0042] The communication module (140) can transmit data transmitted from the memory (130) to the printer (170).
[0043] At this time, there may be differences in data processing speed and capacity between the memory (130), the communication module (140), and the printer (170). To overcome these differences, the system transmitting the power plant status screen may use a buffer (150). Here, the buffer (150) is designed to prevent speed imbalance between the memory (130) and the communication module (140), and excess data can be accumulated and transmitted when a network bottleneck occurs.
[0044] The buffer (150) is a temporary storage space for storing data for a while, and the central processing unit (120) can adjust the buffer (150) to ensure a smooth data flow. For example, if the speed at which the memory (130) transmits data to the communication module (140) is faster than the speed at which the communication module transmits data to the printer (170), the buffer (150) can temporarily store the data being transmitted from the memory (130) to the communication module (140) and then transmit it to the communication module (140).
[0045] According to one embodiment of the present invention, a screen storage method for real-time transmission of a power plant status screen can capture a power plant status screen (110) in real-time and transmit it to an external system (not shown) or a printer (170) using a lower capacity memory compared to a conventional method that requires a large capacity memory.
[0046] FIG. 2 is a flowchart showing a method for transmitting a power plant status screen in real time according to an embodiment of the present invention.
[0047] The power plant status screen transmission system (100) illustrated in FIG. 1 is a system for transmitting a power plant status screen in real time and may include a power plant status screen (110), a central processing unit (120), a memory (130), and a communication module (140). Additionally, the power plant status screen transmission system (100) may further include a buffer (150). Additionally, the power plant status screen transmission system (100) may further include a screen capture and transmission interface (160).
[0048] The power plant status screen (110) can provide the operator with real-time visualization of the operating status of complex equipment within the power plant or the operating status of various control systems.
[0049] First, the central processing unit (120) receives a command to capture and transmit a power plant status screen from an operator through a screen capture and transmission interface (160) (S200).
[0050] The central processing unit (120) passes the collected screen data from the first point (113) of the power plant status screen corresponding to the time when the screen capture and transmission command is received up to the second point, which is the end point of the screen, without storing it in the memory (130) (S210).
[0051] The central processing unit (120) collects screen data from the third point (116) of the power plant status screen where the screen starts and stores it in memory (130) (S220).
[0052] If there is a difference between the screen data and the data collected from the third point (116) at the time the screen capture and transmission command is input, the central processing unit (120) checks the difference between the data and updates the part of the data that differs with the latest screen data and stores it in memory (130).
[0053] The central processing unit (120) transmits the data loaded in the memory (130) to the communication module (140) when the free space of the memory (130) falls below a first threshold or when the loaded data exceeds a second threshold (S230). Here, the communication module (140) may be a chip, modem, hub, or a module capable of processing a printer protocol that handles the physical layer of transmission.
[0054] The communication module (140) transmits data transmitted from the memory (130) to the printer (170) (S240).
[0055] The central processing unit (120) stores the data transmitted from the memory (130) to the communication module (140) at a specific address in the buffer (150) when the speed at which the memory (130) transmits data to the communication module (140) is faster than the speed at which the communication module (140) transmits data to the printer (170).
[0056] The central processing unit (120) transmits data stored at a specific address of the buffer (150) to the communication module (140) when the speed at which the memory (130) transmits data to the communication module (140) and the speed at which the communication module (140) transmits data to the printer (170) are maintained within a predetermined transmission speed range.
