[0002] With the development of distributed control systems, the centralized monitoring method of the main control room is adopted in large control systems. The main control room is usually equipped with multiple operation stations and a large-screen display system, where each operation station is used to monitor each sub-system in the factory, and the large-screen system is used to display the status and parameters of the main parameters and important systems and equipment. The large screen is arranged in front of the main control room and can be observed by all personnel entering the main control room, which is convenient for cooperation between team members and coordination of various activities. It is an extremely effective means to quickly grasp important parameters, especially in the case of shift handover or incident / accident.

[0003] However, in the prior art, factories (e.g., post-processing plants) have many sub-systems with different functions, many important parameters related to production status, and widely distributed sub-systems.

[0069] In order to make those skilled in the art better understand the technical scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and Examples. It should be understood that the specific embodiments described herein are only intended to explain the application, rather than to limit the application. For those skilled in the art, the application can be implemented when some details in these specific details are not needed. The following description of the embodiments is only for providing a better understanding of the application by illustrating the examples of the application.

[0070] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0071] In the related art, there are many sub-systems in the post-processing plant, and the functions of the sub-systems are different. There are many important parameters related to the production status and the distributed systems are wide. On the one hand, it is difficult to maintain a balance between the overall production status and the local monitoring parameters in the display screen of the large screen in the main control room. That is, if the large screen uses the screen of each sub-system for monitoring, it will cause the large screen to include too much monitoring information, and the information is cumbersome, which is not conducive to the operator's overall grasp of the production status; if the selected monitoring parameters are too simple, it will cause the large screen to include too little monitoring information, and the operator will find it difficult to grasp the local details of the production status because he cannot get enough information. On the other hand, during the switching process of the display screen of the large screen in the main control room, the minimum display unit in the display screen is not unified, and there may be a problem that the minimum display unit is difficult to meet the visual needs of the back-row operators in the main control room.

[0072] The inventors have found that by dividing the large screen into areas during the display process of the large screen in the main control room and arranging the overall status picture and the local detail picture in each display sub-area, the display picture of the large screen can be optimized, so that the display picture projected on the large screen maintains a balance between the overall production status and the local monitoring parameters, meeting the large screen display requirements; in addition, through the display size of the minimum display unit on the large screen, the target minimum display unit that meets the optimal operating visual requirements of the operators in the main control room (back row operators, for example, at least two rows of operators) is determined, so that the operators can quickly and accurately understand the operating status of the factory and ensure the safe, reliable and stable operation of the factory.

[0073] Based on this, in order to solve the problems of the prior art, the present invention proposes a display method and device for a large screen in the main control room, which can maintain a balance between the overall production status and local monitoring parameters of the display screen projected on the large screen in the main control room, and can also meet the operational visual needs of the large screen users.

[0074] Embodiment 1:

[0075] like Figure 1 As shown, an embodiment of the present invention provides a method for displaying a large screen image in a main control room, the method comprising steps S1 to S4:

[0076] Step S1. Obtain a set of monitoring images under any working condition.

[0077] Here, any operating condition refers to the normal operating condition of the equipment in the factory or the abnormal operating condition of the equipment in the factory. Specifically, the normal operating condition can be the condition of the nuclear fuel reprocessing plant processing spent fuel normally; the abnormal operating condition can be, for example, the condition of the nuclear fuel reprocessing plant repairing, maintenance, and abnormal shutdown. It can be understood that different operating conditions are the operating conditions formed by each sub-system in the factory at different times.

[0078] A set of monitoring screens for any working condition may be composed of multiple screens, for example, the set of monitoring screens may include an overall production status screen and a local production detail screen. In some embodiments, the overall production status screen includes at least one of a monitoring screen of the entire factory, an overall process flow chart, an overall trend screen, an overall alarm screen, an overall operation record screen, etc. The local production detail screen is a monitoring screen of each sub-item system. For example, a local monitoring screen of each sub-item system, at least one of a local process flow chart of the sub-item system, a local trend screen of the sub-item system, a local alarm screen of the sub-item system, etc.

[0079] In some other implementations, a set of monitoring images also includes a personnel visit display image. During implementation, the personnel visit display image is formed by integrating each operator station, and the personnel visit display image is projected onto a large screen for display. Large screen visitors can visit through a viewing corridor outside the main control room, thereby realizing efficient display of the large screen system.

[0080] It should also be noted that the factory can specifically be a nuclear fuel reprocessing plant, which is an industrial facility used to process spent fuel removed from a nuclear reactor and recover usable fissile materials (such as plutonium and uranium) therefrom. The sub-systems in the reprocessing plant include: receiving and storing spent fuel, cutting and dissolving fuel elements, chemical separation, and concentrating and solidifying high-level waste liquid. It should be noted that the factory can also be other factories with many sub-systems, different functions of the sub-systems, more important parameters involving the factory status, and widely distributed systems, and the present invention does not limit this.

[0081] In some embodiments, each sub-system may be further divided into multiple process sections. For example, the concentration of high-level waste liquid may be further divided into process sections such as evaporation concentration, purification, denitrification, and calcination. It should be noted that the classification method of the sub-systems in this embodiment is only an example, and each post-processing process may be divided into multiple sub-systems in other classification methods, which is not limited by the present invention.

[0082] In some embodiments, a display screen is provided in the main control room, and the display screen includes an operator station located in the main control room for monitoring each sub-system respectively and a large screen located in the front of the main control room.

[0083] Specifically, the operator station is a display screen set up in the main control room for each sub-system of the factory. The operator station is used to display the monitoring screen of each sub-system so as to display each sub-system in detail. For example, the operator station set up for the high-level evaporation process section (one of the concentration steps of high-level waste liquid) can monitor the high-level evaporation process section in real time.

[0084] It should be noted that each sub-system can be configured with an operator station, and an operator can manage the sub-system. The number of display screens of the operator station corresponding to each sub-system can be 1, 2, 3, or other numbers. In some embodiments, the process sections in the post-processing plant are divided according to the monitoring capability of each operator station to form multiple sub-systems.

[0085] In some implementations, a supervisor station for managing each operator station is also provided in the main control room to integrate the monitoring screens of the sub-systems of each operator station to form an overall status screen of production.

[0086] During implementation, a correspondence between the overall status screen and the local detail screen of production under any working condition can be established, and the overall status screen and the local detail screen of production under each working condition can be obtained according to the above correspondence. It is also possible to obtain the local detail screen under each working condition from each operator station, and obtain the overall status screen under the working condition from the shift supervisor station, so that the operator can project the local detail screen and the overall status screen onto the large screen, and enlarge the display of each sub-system in the factory.

[0087] Step S2: Divide the large screen into a plurality of display sub-areas, and arrange the group of monitoring pictures in each display sub-area of ​​the large screen to form a group of display pictures on the large screen.

[0088] Here, the display sub-area is a plurality of display sub-areas formed in the large screen after the large screen is divided into regions. The area size of each display sub-area in the plurality of display sub-areas may be the same or different. In some embodiments, the area size of each display sub-area may be pre-configured according to the viewing requirements of the monitoring screen.

[0089] A group of display pictures, that is, multiple pictures are displayed on the large screen at the same time. For example, when a group of monitoring pictures includes the overall status picture of production and the local detail picture, a group of display pictures including the overall status picture of production and the local detail picture are displayed on the large screen at the same time.

[0090] It should be noted that a group of display images on the large screen will be switched. During the switching process, the area size of each display sub-area corresponding to each group of display images can be fixed or dynamically adjusted. In some embodiments, the area size of each display sub-area can be determined based on the balance requirements between the overall status image and the local detail image.

[0091] In addition, the position of each display sub-area in the large screen can be determined based on the principle that the most target operators can clearly see it. For example, the overall status picture of production can be projected to any position of the large screen so that the target operators can clearly see the large screen. In some embodiments, the overall status picture of production can also be projected to the middle position of the large screen so that operators on both sides can clearly see the large screen.

[0092] Step S3: Obtain the smallest display unit in the group of display pictures on the large screen.

[0093] Here, the minimum display unit in a group of display screens is the minimum functional unit in the screens displayed by the multiple display sub-areas. The minimum display unit can be pre-defined according to the content of the monitoring screen. Specifically, the minimum display unit includes at least one of the identifier of the equipment status and the identifier of the section process in the current overall operation status of the post-processing plant, the identifier of the safety-related parameters of the post-processing plant (for example, characters), and the identifier in the video monitoring of the accident site.

[0094] During implementation, the minimum display unit in the display screen is predefined according to the minimum information requirement that the operator needs to clearly see in the display screen on the large screen. According to the predefined minimum display unit in the display screen, the minimum display unit in each group of display information is determined.

[0095] Step S4: Adjust the display size of the minimum display unit on the large screen to determine the target minimum display unit that meets the optimal working visual requirements of the operator.

[0096] When the smallest display unit can meet the operator's optimal working visual needs, the other display units on the large screen will inevitably also be able to meet the operator's visual needs.

[0097] Here, the optimal operation visual requirement may be to simultaneously meet the visual requirements of operators corresponding to multiple rows of operator stations in the main control room, and to reserve the visual requirements of operators at a certain distance behind the last row of operator stations. For example, the optimal operation visual requirement is to simultaneously meet the visual requirements of operators corresponding to two rows of operator stations in the main control room, and to reserve the visual operation requirements of operators corresponding to one row of operator stations in the second row of operator stations.

[0098] In some other implementations, the users of the large screen can also be visitors in the viewing gallery of the main control room. At this time, the minimum display size of the minimum display unit on the large screen is adjusted to determine the target minimum display unit that meets the best visual needs of the visitors. During implementation, the target minimum display unit that meets the best visual needs of the visitors is determined by integrating the visitor display screen of each operator station, and the visitor display screen is projected onto the large screen for display. Visitors to the large screen can visit through the viewing gallery outside the main control room without affecting the operator's operation, thereby achieving efficient display of the large screen system.

[0099] During implementation, first verify whether the display size of the smallest display unit in each group of display images on the large screen can meet the visual needs of the operators in the main control room. If it does, the group of display images can be projected onto the large screen; if it does not, make adjustments until the target smallest display unit that meets the optimal visual needs of the operators is determined.

[0100] Here, adjusting the display size of the minimum display unit on the large screen can be to optimize a group of monitoring images (for example, when the obtained minimum display unit is too small, such as smaller than the minimum size threshold of the minimum display unit), a larger minimum display unit can be defined; and / or, the sizes of multiple display sub-areas can be optimized (for example, when the obtained minimum display unit is too small, such as smaller than the minimum size threshold of the minimum display unit), the area of ​​the display sub-area of ​​the image corresponding to the minimum display unit in the large screen can be adjusted.

[0101] In this embodiment, by acquiring a group of monitoring screens under any working condition and forming a group of display screens on the large screen, the minimum display unit of each screen in a group of display screens can be determined, and then the display size of the minimum display unit on the large screen can be adjusted to determine the target minimum display unit in the large screen that meets the optimal working visual needs of the operators, so that during the display process of the large screen, it is convenient for the operators to clearly view the various display screens on the large screen, thereby improving the coordination and cooperation between the operators in the main control room.

[0102] In some embodiments, the set of monitoring images includes an overall production image, a local detail image, and a shift handover image.

[0103] Step S2 specifically includes steps S21 to S22:

[0104] Step S21. Divide the large screen into multiple display sub-areas according to the weights of the overall production status screen, the local detail screen and the shift handover crew screen on the large screen.

[0105] Here, a group of weights of the overall production status screen, the local production detail screen and the shift handover crew screen in the large screen are configured to divide the large screen into multiple display sub-areas.

[0106] It is understandable that by adjusting the weight of each screen on the large screen, the area of ​​the multiple display sub-areas divided by the large screen can be adjusted. In some embodiments, the weight of the shift handover crew screen on the large screen is set according to the shift handover requirements to adjust the area of ​​the corresponding display sub-area of ​​the shift handover crew screen on the large screen. For example, in the shift handover time period or a period of time before and after the shift handover time period, a larger weight of the shift handover crew screen on the large screen is configured to enlarge the area of ​​the display sub-area of ​​the shift handover crew screen on the large screen; in the time period outside the shift handover time period, a smaller weight of the shift handover crew screen on the large screen is configured to reduce the area of ​​the display sub-area of ​​the shift handover crew screen on the large screen.

[0107] In some embodiments, during time periods outside of the shift handover time period, only the display sub-areas corresponding to the overall production status screen and the local production detail screen are configured to fully display the overall production status screen and the local production detail screen.

[0108] Step S22: Arrange the overall production status picture, the local detail picture and the shift handover picture in the corresponding display sub-areas respectively, so as to form a group of display pictures on the large screen.

[0109] Here, the overall factory status screen, local detail status screen and shift handover unit screen are simultaneously arranged on the large screen, which can meet the operational needs of factory operators while taking into account the balance between the overall production status and local monitoring parameters.

[0110] In this embodiment, by dividing the large screen and arranging a group of monitoring images into each display sub-area, the balance between the overall production status and local monitoring parameters as well as the operating needs of the operators can be met, which facilitates the handover and coordination of the operators.

[0111] In some embodiments, the main control room is provided with an operator station and a shift supervisor station for managing each operator station. The operator station is used to monitor each sub-system in production. The set of monitoring screens includes an overall screen of production and a local detail screen.

[0112] Step S1 specifically includes:

[0113] A local detail screen of sub-system monitoring under any working condition is obtained from the operator station, and an overall status screen of production under the working condition is obtained from the shift supervisor station to form a set of monitoring screens under the working condition.

[0114] Here, the operator station can monitor each sub-system in the factory to form a local detail picture; the shift supervisor station manages each operator station to form an overall status picture.

[0115] In some embodiments, the partial detail images are projected onto the large screen through the duty officer station, so that the duty officer station allocates the display sub-areas in the large screen. In some other embodiments, the partial detail images can also be directly projected onto the display sub-areas of the large screen through each operator station to improve display efficiency.

[0116] In some embodiments, the operator stations are arranged in multiple rows in the main control room, and each row of operator stations is distributed in front of both sides of the large screen, and the shift leader station is arranged in front of the middle of the large screen. In some embodiments, the shift leader station is arranged behind all the operator stations to manage all the operator stations. At this time, the optimal operation visual demand can be to simultaneously meet the visual demand of the operator corresponding to the shift leader station in the main control room, and the visual demand of the operator at a certain distance reserved behind the shift leader station.

[0117] Step S2 specifically includes:

[0118] Divide the large screen into a middle area and side areas located on both sides of the middle area;

[0119] The local detail picture is arranged in the side area of ​​the large screen close to the corresponding operator station, and the overall status picture is arranged in the middle area of ​​the large screen.

[0120] Here, the local detail picture placed on the large screen can be a local detail picture in the display screen of the operator station, or multiple local detail pictures can be placed on the corresponding display sub-area at the same time. For multiple local detail pictures placed on the corresponding display sub-area at the same time, for example, there are 15 flow charts for the high-pressure evaporation process section in the 109 sub-item operator station, but there are only 3 LCD monitors in front of the operator, and only 3 flow charts can be displayed at the same time. At this time, the 109 sub-item large screen flow chart picture can be placed on the large screen.

[0121] In some other embodiments, the local detail image can also be projected to the middle area of ​​the large screen so that operator stations located on different sides can interact with each other. When the operator of sub-item 103 views the relevant parameters of the dissolver of sub-item 102.

[0122] In this embodiment, by acquiring the local detail screen, acquiring the overall status screen, laying out the local detail screen, and laying out the overall status screen, the operator station can clearly view the local detail screen projected on the large screen, so as to timely discover monitoring anomalies and improve monitoring efficiency.

[0123] In some embodiments, step S3 specifically includes steps S31 to S32:

[0124] Step S31. Determine the minimum functional unit of each display screen in a group of display screens corresponding to any working condition;

[0125] The minimum functional unit includes the first minimum functional unit in the overall production status screen, the second minimum functional unit in the local detail screen, and the third minimum functional unit in the shift handover screen.

[0126] The first minimum functional unit includes at least one of the minimum functional units required to be displayed for the equipment status and the work section process in the current overall operating status; the second minimum functional unit includes at least one of the minimum functional units required to be displayed for safety-related parameters, process parameters of the sub-system, and video surveillance of the accident scene; and the third minimum functional unit includes the minimum functional unit required to be displayed in the application required by the operator team.

[0127] Here, the minimum functional unit may be predefined according to the monitoring requirements of the monitoring screen.

[0128] Step S32: Compare the sizes of the first smallest functional unit, the second smallest functional unit and the third smallest functional unit in each group of display images, and determine the smallest one among the three as the smallest display unit in each group of display images under each working condition.

[0129] During implementation, the sizes of the minimum functional units are compared to determine the minimum values ​​of the sizes of the first minimum functional unit, the second minimum functional unit and the third minimum functional unit as the minimum display unit in each group of display images.

[0130] In this embodiment, by determining each minimum functional unit and the minimum display unit, the minimum display unit in a group of display images in the large screen can be determined, providing a basis for subsequently determining the minimum display unit in the large screen that meets the visual needs of the operators.

[0131] In some embodiments, step S4 specifically includes steps S41 to S43:

[0132] Step S41: Obtain the display size of the minimum display unit.

[0133] Here, the display size of the minimum display unit is the size of the identifier or character of the minimum display unit in the vertical direction, for example, the character height. In some other embodiments, the display size of the minimum display unit can also be obtained, that is, the size of the identifier or character of the minimum display unit in the horizontal direction, for example, the character width.

[0134] Step S42. Calculate the minimum size threshold of the minimum display unit according to the following formula (1):

[0135] D1=L1*k1 (1)

[0136] Wherein, D1 is the minimum size threshold of the smallest display unit on the large screen, L1 is the minimum visible distance threshold of the large screen, and k1 is the first calculation coefficient;

[0137] And, the maximum size threshold of the minimum display unit is calculated according to the following formula (2):

[0138] D2=(L1+L2)*k2 (2)

[0139] Among them, D2 is the maximum size threshold of the smallest display unit on the large screen, L1 is the minimum visible distance threshold of the large screen, L2 is the minimum visible distance threshold margin of the large screen, and k2 is the second calculation coefficient.

[0140] Here, the minimum visual distance threshold value L1 of the large screen is the distance corresponding to the visual needs of the operators at the last row of operator stations in the main control room (i.e., the distance between the large screen and the last row of operator stations), and the maximum visual distance threshold value of the large screen is the distance corresponding to the visual needs of the operators corresponding to a certain distance L2 reserved after the last row of operator stations. For example, L2 can be the size margin for reserving a row of operator stations in the last row of operator stations, and (L1+L2) is the distance corresponding to the visual needs of the operators at the last row of operator stations reserved for a row of operator stations (i.e., the distance between the large screen and the reserved row of operator stations).

[0141] In some other embodiments, the large screen is used by visitors in the viewing gallery of the main control room, and a transparent display window is provided in the viewing gallery so that visitors can view the viewing display screen on the large screen through the transparent display window. At this time, L1 is the distance corresponding to the visual needs of visitors at the position farthest from the large screen in the transparent display window (i.e., the longest distance between the large screen and the transparent display window), and L2 can be the size margin on the extension line of the farthest position between the large screen and the display window. For example, the farthest position between the large screen and the display window can be extended to form an intersection on the side of the viewing gallery away from the transparent display window, and L2 is determined based on the farthest position and the intersection, and (L1+L2) is the distance between the intersection and the large screen.

[0142] The first calculation coefficient and the second calculation coefficient are empirical parameters, and their values ​​may be the same or different. In some embodiments, k2≥k1. The first calculation coefficient and the second calculation coefficient may range from 0.003 to 0.005, for example, both are 0.004.

[0143] Step S43: Verify whether the display size of the minimum display unit on the large screen is appropriate based on the calculated minimum size threshold and maximum size threshold of the minimum display unit, so as to determine the target minimum display unit that can meet the optimal working visual requirements of the operator.

[0144] During implementation, the display size of the smallest display unit of the large screen is compared with the minimum size threshold and the maximum size threshold of the smallest display unit to verify the display size of the smallest display unit.

[0145] like Figure 3As shown, there are two rows of operator stations, a row of shift supervisor stations behind the operator stations, and a large screen in front of the operator stations. The minimum visible distance threshold is the visible distance of the operator in the row of shift supervisor stations behind the operator stations. (L1+L2) is the visible distance of the operator in the row of shift supervisor stations reserved behind the shift supervisor stations.

[0146] For example, if the display size of the obtained minimum display unit (such as character height) is 3.2cm, L1 is 750cm, and (L1+L2) is 900cm. When k1 and k2 are both 0.004, it can be determined that D1 is 3cm and D2 is 3.6cm, then it is verified that the display size of the minimum display unit on the large screen is 3.2cm, which is appropriate and can meet the operator's work visual needs. If the display size of the obtained minimum display unit (such as character height) is 2.8cm, which is less than the minimum size threshold of 3cm, then it is verified that the display size of the minimum display unit on the large screen is not appropriate and cannot meet the operator's optimal work visual needs, and the minimum display unit on the large screen needs to be adjusted.

[0147] In this embodiment, by obtaining the character height of the minimum display unit, calculating the minimum size threshold and the maximum size threshold of the minimum display unit, and verifying the minimum display unit of the large screen, it is possible to determine the target minimum display unit that meets the optimal working visual needs of the operator while meeting the large-screen display requirements.

[0148] In some embodiments, step S43 specifically includes steps S431 to S433:

[0149] Step S431. Determine whether the display size of the smallest display unit of the large screen is between the minimum size threshold and the maximum size threshold;

[0150] Step S432: If yes, determine that the minimum display unit is the target minimum display unit that meets the operator's work visual requirements.

[0151] Here, the display size of the minimum display unit of the large screen is between the minimum size threshold and the maximum size threshold, that is, a group of monitoring screens that have been determined and the weight of each screen on the large screen can be determined to determine the target minimum display unit that meets the optimal working visual needs of the operators.

[0152] Step S433: If not, adjust the display size of the minimum display unit on the large screen until the target minimum display unit is determined.

[0153] Here, if the display size of the determined minimum display unit of the large screen is smaller than the minimum size threshold of the minimum display unit or larger than the maximum size threshold of the minimum display unit, then adjustment is performed. The adjustment process may be to repeatedly execute the determined content of the group of monitoring images, and / or, to divide the display area of ​​the large screen, to determine the minimum display unit in a group of display information, to obtain the character height of the minimum display unit, and to calculate the minimum display unit threshold of the large screen.

[0154] In some embodiments, the content of the determined group of monitoring screens is adjusted. For example, if the display size of the minimum display unit of the large screen is less than the minimum size threshold of the minimum display unit, the actual range monitored by the monitoring screen is reduced to enlarge the display size of the minimum display unit in the monitoring screen; the content of the minimum display unit in the monitoring screen can also be enlarged. Correspondingly, if the display size of the minimum display unit of the large screen is greater than the maximum size threshold of the minimum display unit, the actual range monitored by the monitoring screen is expanded to reduce the display size of the minimum display unit in the monitoring screen; the content of the minimum display unit in the monitoring screen can also be reduced.

[0155] In some embodiments, for example, if the display size of the smallest display unit of the large screen is less than the minimum size threshold of the smallest display unit, the weight of the monitoring screen corresponding to the minimum display unit that does not meet the visual needs of the operator in the main control room can be increased to enlarge the display size of the smallest display unit in the monitoring screen. If the display size of the smallest display unit of the large screen is greater than the maximum size threshold of the smallest display unit, the weight of the monitoring screen corresponding to the minimum display unit that does not meet the visual needs of the operator in the main control room can be lowered to reduce the display size of the smallest display unit in the monitoring screen.

[0156] In this embodiment, by judging the display size of the minimum display unit of the large screen and when the display size of the minimum display unit of the large screen is not between the minimum size threshold and the maximum size threshold, the acquisition of the group of monitoring images and the division of the large screen are repeated to adjust the display size of the minimum display unit on the large screen, and then the acquisition of the minimum display unit and the judgment of the minimum display unit of the large screen are executed to meet the target minimum display unit of the operator's work visual needs, so as to improve the production monitoring efficiency of the operators in the main control room.

[0157] In some embodiments, before step S2, the method further includes step S0:

[0158] Step S0. Determine the display area in the main control room where the large screen is located according to the size of the main control room and the principles of ergonomics;

[0159] The step S0 specifically includes:

[0160] Step S01. Determine the width of the display area of ​​the large screen according to the length of the main control room;

[0161] Here, the width of the display area where the large screen is located should be smaller than the length of the main control room. For example, if the length of the main control room is 39 meters, the width of the display area where the large screen is located should be smaller than 39 meters.

[0162] Step S02: Determine the height of the display area of ​​the large screen according to the height of the main control room and the principle of ergonomics.

[0163] Here, the first elevation of the highest point of the display area where the large screen is located is determined according to the height of the main control room, the second elevation of the lowest point of the display area where the large screen is located is determined according to the principles of ergonomics, and the height of the display area where the large screen is located is determined according to the difference between the first elevation and the second elevation.

[0164] In some embodiments, the second elevation of the lowest point of the display area where the large screen is located determined according to human factors engineering ranges from 0.8 meters to 1.2 meters. In some embodiments, the second elevation of the large screen display area is 1 meter and the first elevation is 3.7 meters.

[0165] In this embodiment, the size of the display area of ​​the large screen is determined by the width and height of the display area where the large screen is located to meet the requirements of the size of the main control room and ergonomic principles, providing a basis for the subsequent layout of each group of monitoring screens in the large screen.

[0166] Embodiment 2:

[0167] The specific implementation process of the above method is described below in conjunction with specific application examples.

[0168] like Figure 2 As shown, the solution of the present invention includes steps S100 to S600:

[0169] Step S100. Analyze the overall demand for the large screen and determine the design goals of the screen display, such as normal operation task screen delivery, emergency command task display, visit and exhibition tasks, etc.

[0170] Specifically, the overall demand analysis includes the following three types of screen delivery.

[0171] (1) Normal operation (normal operating conditions) screen delivery

[0172] Including flow chart screen delivery, real-time trend screen delivery, historical trend screen delivery, alarm screen delivery, instrument bar chart screen delivery, event record screen delivery, operation record screen delivery, etc. Each screen can be delivered to any position on the large screen in any size.

[0173] During normal operation, according to the different positions of the operator stations, a large screen area suitable for observation by the operator station is allocated. At this time, the operator can project the operation screen of the corresponding control system into the exclusive large screen area, so that the large screen and the LCD display in front of the operator can be organically combined to work more efficiently. For example, there are 15 flow charts in the high-pressure evaporation process section in the 109 sub-item operator station, but there are only 3 LCD displays in front of the operator, and only 3 flow charts can be displayed at the same time. At this time, the 109 sub-item large-screen flow chart can be projected into the large screen, or other flow charts that the operator focuses on can be projected into the large screen, and the comprehensive overview of important parameters or historical trend charts can also be projected into the large screen, so as to achieve more efficient human-machine cooperation and reflect the idea of ​​ergonomics.

[0174] When different control systems need to interact, that is, when sub-items in different operating areas interact, the content that operators in different operating areas need to watch can be projected onto the large screen. For example, when the operator of sub-item 103 views the relevant parameters of the dissolver of sub-item 102.

[0175] (2) Abnormal operating conditions (abnormal operation conditions) screen delivery

[0176] In case of some abnormal working conditions, when the operator thinks that the working conditions may affect the operation of other sub-items, or when other sub-item personnel or shift supervisors are required to participate in solving the problem together, the abnormal picture can be projected onto the large screen with a larger picture, so that personnel in all areas of the central control room can quickly see the situation. Furthermore, with the advantages of the networked large-screen system, the abnormal working conditions can be transmitted in real time to the conference room for leadership decision-making, and even to the dispatch center and office network.

[0177] (3) Personnel visit placement

[0178] When personnel visit or leaders inspect, the large screen system can be used for efficient display through the visiting gallery without affecting the operator's operation.

[0179] Step S200: Analyze the space constraints of the large screen design, such as the height and width of the main control room.

[0180] Specifically, the large-screen display area has a minimum elevation of 1 meter and a maximum height of no more than 3.7 meters, and its width must be less than the length of the main control room, which is 39 meters.

[0181] Step S300. Determine the information display requirements of the large screen;

[0182] Specifically, according to the operational requirements, activity characteristics and safety analysis documents of the post-processing plant operation, the display groups (a group of display screens) that need to be designed are analyzed and determined, that is, according to the three display groups of steady-state operation, overview of the status of the shift change unit, and important parameters of the accident condition (during the normal steady-state operation of the system, the operator is provided with necessary unit operation status monitoring information and important parameter trends; during the operator shift change process, the operator who takes over can quickly and conveniently understand the operating status of the entire unit; under accident conditions, the observer can quickly grasp the important parameters). The functional sub-group display weight allocation list of the display group is compiled separately, and the large-screen screen design is carried out in combination with the duty cycle of the screen, the number of screens and other information. After the screen design is completed, the large-screen screen and the weight allocation list are revised in combination with the review opinions of process experts. The screen placement of the three display groups adopts a dynamic allocation scheme, and the screens that need to be displayed on the large screen can be adjusted according to the actual operating conditions of the post-processing plant.

[0183] Step S400. Determine the screen type and quantity of the large screen;

[0184] Specifically, currently, there are several technical solutions for selecting large screens: LCD narrow-edge splicing (ie liquid crystal splicing), small-pitch LED, laser phosphor DLP, LED light source DLP and laser light source DLP.

[0185] LCD narrow-edge splicing (liquid crystal splicing) has the advantages of high overall brightness, good color effect, high contrast, high resolution and long service life, but its fatal flaw is that the splicing seam is too large. The current mainstream product has a splicing seam of 1 cm, and some high-end products have a splicing seam of 3.5 mm. In addition, the size of a single screen is small, with the mainstream being a 55-inch screen. If applied, the splicing of dozens or even hundreds of units will result in large black seams everywhere on the large screen, and the overall effect is not good. Moreover, due to the large seam, information and data will be lost when used for display.

[0186] Small-pitch LEDs are suitable for outdoor display under high-brightness conditions. The brightness in front of the screen is very high. Long-term viewing indoors will cause eye fatigue and even vision loss and tears. The image quality is not high, the display details are poor, the light conversion efficiency is poor, and the energy consumption is very high.

[0187] Laser phosphor DLP is a technology that is on the verge of being eliminated by the market. It has the advantages of high overall brightness and low energy consumption, but its disadvantage is that the color wheel life is too short and needs to be replaced regularly (1 to 2 years). In addition, the phosphor wheel is prone to color deviation, the color printed by the phosphor is unstable, and the color consistency cannot be adjusted.

[0188] LED light source DLP is the mainstream product for large screens in control rooms today. It has the advantages of good overall effect, long life (light source life> 80,000 hours, non-stop operation for more than 9 years), high resolution (full HD), and small seams (0.5mm). Its disadvantages are slightly lower brightness and higher cost (orders of magnitude higher than LCD products).

[0189] Laser light source DLP is a new generation of large screen products for control rooms. Compared with LED light source DLP, it has the following advantages: screen display brightness is twice that of LED, richer color gamut, better effect, richer contrast, smaller seam (0.1mm), longer life (light source life of 100,000 hours, can run 24 hours a day for 11 years), low light source noise (30db), low power consumption (70 inches 120W). Its disadvantage is that the cost is higher, 1 / 3 higher than that of LED light source DLP.

[0190] In this embodiment, a laser light source DLP technology large screen system is used. The large screen uses 2*12 sub-screens, and the size of a single sub-screen is 80 inches. Specifically, Figure 4 As shown, the large screen (B1) is composed of 24 sub-screens (B1') arranged in two rows, each row has 12 sub-screens, and the large screen is rectangular as a whole. For example, a set of monitoring images obtained is the overall picture of production under normal working conditions, the local detail picture, and the handover group picture. The 2*12 sub-screens can be divided into 2*5 sub-screens (display sub-area A1), 2*5 sub-screens (display sub-area A2) and 2*2 sub-screens (display sub-area A3) in the horizontal arrangement direction, and then the overall picture of production can be arranged in the display sub-area A2, the local detail picture can be arranged in the display sub-area A1, and the handover group picture can be arranged in the display sub-area A3.

[0191] It should also be noted that the overall screen of the production is arranged in the display sub-area A2, which is the middle area of ​​the large screen. The middle area of ​​the large screen does not need to be at the symmetrical center of the large screen, but can be the middle area of ​​multiple display sub-areas arranged in the horizontal direction.

[0192] Step S500. Determine the minimum information display unit (minimum display unit) of the screen in combination with the information display content;

[0193] Specifically, the minimum information display unit (minimum functional unit) of the large screen includes at least the following functions:

[0194] (1) The overall current operating status of the post-processing plant, and the status of the main processes and equipment of each sub-item;

[0195] (2) Display of the main safety-related parameters of the post-processing plant and the safety function driving results in each sub-item;

[0196] (3) Process simulation diagrams of each sub-item, important alarms, and display of important states and parameters;

[0197] (4) Flexible application of operator team requirements;

[0198] (5) Important on-site video surveillance;

[0199] (6) The operator can run dynamic navigation links on the large screen display. The large screen system is used to help the operator and personnel in the main control room quickly understand the status of the reprocessing plant.

[0200] The large-screen image projection adopts a dynamic allocation solution, which can adjust the corresponding images that need to be displayed on the large screen according to the actual operating conditions of the post-processing plant.

[0201] Step S600. Determine the viewing distance threshold of the large screen in combination with the relevant standards of ergonomic design and the position setting of the main control room; then adjust the font height of the large screen according to the viewing distance threshold of the large screen.

[0202] Specifically, according to the overall layout requirements of the main control room, the first two rows of operators are the main users of the large screen, so the lowest layout position of the large screen must meet the operating visual requirements of the second row of operators in the main control room (that is, the distance between the large screen and the second row of operators is the minimum visual distance threshold), for example, the minimum visual distance threshold can be 600-800cm, preferably 750cm. In addition, a row of operator stations is reserved after the second row of operators, and the maximum visual distance threshold can be determined, for example, the maximum visual distance threshold can be 800-1000cm, preferably 900cm.

[0203] According to the empirical formula: large screen font height = visual distance threshold * 0.004. Considering that the distance between the second row of operators and the large screen is 750cm, and considering that the distance between the reserved row of operator stations behind the second row of operators and the large screen is 900cm, the font height on the large screen is between 3cm and 3.6cm, which is the best target minimum display unit.

[0204] Figure 3 A structural diagram of a post-processing plant main control room provided by an embodiment of the present invention, such as Figure 3 As shown, the main control room includes multiple operator stations and a large screen arranged in front of the operator stations. In some embodiments, a shift supervisor station for managing each operator station is also arranged in the main control room. The operator station can project images directly on the large screen, and can also project images to the large screen through the shift supervisor station.

[0205] In this embodiment, through the overall demand analysis of the large screen, space constraint analysis, determination of information display requirements, screen selection and quantity, and adjustment of the minimum information display unit, the target minimum display unit that fully meets the operator's visible distance threshold (minimum visible distance threshold and maximum visible distance threshold) requirements can be determined, so that the operator can quickly and accurately understand the operating status of the post-processing plant and ensure the safe, reliable and stable operation of the post-processing plant.
