[0053] 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.

[0054] 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.

[0055] In the related art, the workshop production management system mainly relies on the corresponding two-dimensional charts to monitor the actual performance of production planning, equipment operation status, material storage status, safety and environmental protection status, energy / quality, etc. Although this method can manage most of the production process data, it is difficult to quickly and intuitively view the actual production status of equipment, materials, etc. in each discrete workshop for discrete manufacturing plants (factories where the shape and combination of materials change during the production process), and the workshop production management data has low timeliness.

[0056] The inventors have found that it is possible to build a virtual model of a physical factory and use digital twin technology to map the actual production process to the virtual model. This can assist workshop execution and management personnel to quickly and intuitively view the actual production conditions of equipment, materials, etc. in the workshop, thereby improving the timeliness of workshop production management data.

[0057] Based on this, in order to solve the problems of the prior art, the present invention proposes a workshop production management method and device based on digital twin technology, so as to view the actual situation of workshop production in real time and quickly, and improve the timeliness of workshop production management data.

[0058] Embodiment 1:

[0059] like Figure 1 As shown, this embodiment provides a workshop production management method based on digital twin technology, which can be applied to nuclear power plants, including steps S1 to S3:

[0060] S1. Obtain a three-dimensional model of the workshop; the three-dimensional model is used to simulate the internal structure of the workshop, including a simulated factory building, equipment in the simulated factory building, and a simulated process route of the equipment.

[0061] Here, the simulated plant buildings include the nuclear island building (also known as the nuclear island) and the conventional island building (also known as the conventional island). The nuclear island includes the reactor building (containment building) and the nuclear fuel building. The conventional island includes the steam turbine generator building and the power transmission and distribution building.

[0062] Specifically, the equipment in the reactor building includes: the reactor pressure vessel that contains nuclear fuel and coolant, the primary circuit system (including the coolant pump that pushes the coolant to flow inside the reactor, the steam generator that converts the heat generated by the reactor into steam, and the regulator that regulates the pressure of the reactor coolant, etc.) and the control rod drive mechanism that controls the power level of the reactor. The equipment in the nuclear fuel building includes the fuel loading and unloading system for loading new fuel and unloading spent fuel, and the fuel storage pool for temporarily storing spent fuel.

[0063] In some embodiments, the nuclear island further includes a primary loop auxiliary plant, wherein the equipment includes: a coolant treatment system for maintaining the chemical composition and system volume of the coolant, a boric acid system for adjusting the boron concentration in the coolant to control reactivity, etc. In some embodiments, the nuclear island further includes a main control room, wherein the equipment includes a control system for monitoring and controlling the operating status of the reactor and a safety system console for monitoring and activating the safety system.

[0064] In addition, the equipment in the steam turbine generator plant includes: The equipment in the steam turbine generator plant includes the steam turbine that converts the thermal energy of steam into mechanical energy, and the generator that converts the mechanical energy of the steam turbine into electrical energy. The equipment in the power transmission and distribution plant includes: The boosting equipment used to boost the electricity generated by the generator and transmit it to the power grid.

[0065] In some embodiments, the equipment in the steam turbine generator plant also includes a condenser for condensing steam exhausted from the steam turbine back into water and a feed water pump for returning the condensed water back to the steam generator.

[0066] The process routes of the simulated equipment include the process routes of the equipment in the nuclear island and the process routes of the equipment in the conventional island.

[0067] Specifically, the process routes of the equipment in the nuclear island include: the first process route of the reactor pressure vessel, the second process route of the coolant pump, the third process route of the steam generator, the fourth process route of the pressurizer, and the fifth process route of the control rod drive mechanism. Among them, the first process route represents the process route in which the nuclear fuel rods in the reactor undergo fission reactions under the regulation of the control rods to generate a large amount of heat energy; the second process route represents the process route in which the coolant pump drives the coolant to circulate between the reactor pressure vessel and the steam generator; the third process route represents the process route in which the heat in the coolant in the steam generator is transferred to the water on the secondary side to generate high-temperature and high-pressure steam; the fourth process route represents the process route in which the pressurizer controls the pressure of the primary circuit by spraying or heating; and the fifth process route represents the process route in which the control rods move up and down to adjust the power level of the reactor.

[0068] In some embodiments, the process route of the equipment in the nuclear island also includes the process route of the equipment in the primary auxiliary plant, including: the sixth process route of the coolant treatment system and the seventh process route of the boric acid system. The sixth process route represents the process route of the coolant treatment system to maintain the chemical composition of the coolant, such as pH value, oxygen content, etc.; the seventh process route represents the process route of the boric acid system to adjust the neutron absorption rate of the coolant by adding boric acid, thereby controlling the reactivity.

[0069] In addition, the process routes of the conventional island equipment specifically include: the eighth process route of the steam turbine, the ninth process route of the generator and the tenth process route of the boosting equipment. Among them, the eighth process route represents the process route in which the steam turbine receives high-temperature and high-pressure steam from the steam generator, drives the turbine blades to rotate through the expansion of the steam, and generates mechanical energy; the ninth process route represents the process route in which the generator is coaxially connected to the steam turbine and converts the mechanical energy of the steam turbine into electrical energy; the tenth process route represents the process route in which the electricity generated by the generator is boosted and transmitted to the power grid.

[0070] In some embodiments, the process route of the conventional island equipment also includes the process route of the equipment in the steam turbine generator plant, including: the eleventh process route of the condenser and the twelfth process route of the feedwater pump. The eleventh process route represents the process route of the condenser condensing the low-pressure steam discharged from the steam turbine into water; the twelfth process route represents the process route of the feedwater pump sending the water in the condenser back to the steam generator to complete the steam cycle.

[0071] It can be understood that, in a nuclear power plant, the first process route, the second process route, the third process route, the eighth process route, the ninth process route and the tenth process route constitute the energy process route in the nuclear power plant.

[0072] It should be noted that each device and each process route has a unique identifier in the three-dimensional model. For example, each device and each process route can be numbered to represent each device and each process route in the three-dimensional model. In some embodiments, each process route is divided into multiple levels according to categories to quickly obtain the number of the corresponding process route.

[0073] During implementation, SolidWorks or Inventor or other three-dimensional modeling software can be used to create a 3D model. The 3D model can be created based on the equipment distribution in the workshop and the process route of the equipment operation, or it can be created based on the existing two-dimensional graphics of the equipment and process route.

[0074] It can be understood that in this embodiment, the 3D model of the workshop obtained is a 3D, stereoscopic virtual model of the physical factory, which can intuitively and stereoscopically display the 3D model of each workshop, and further be used for fine monitoring and optimized management of the physical factory. In a nuclear power plant, the equipment in each plant in the nuclear island and conventional island and the process route of each equipment can be intuitively and stereoscopically displayed.

[0075] S2. Obtain real-time measurement data and historical statistical data in workshop production; the real-time measurement data includes first equipment data, first material data, first safety and environmental data, and first energy data; the historical statistical data includes second equipment data, second material data, second safety and environmental data, and second energy data.

[0076] Here, the first equipment data includes the on / off status of the equipment in each plant, current and voltage data, and mechanical data detected by sensors installed on the equipment (for example, detection data of the position of the control rod in the control rod drive mechanism). The first material data includes the measurement data of the nuclear fuel in the nuclear fuel plant (loaded amount, unloaded amount, storage amount in the storage pool) and the distribution measurement data in the reactor pressure vessel. The first safety and environmental data includes the radiation monitoring data of the containment plant and the outside of the containment plant, and the smoke monitoring data in each plant.

[0077] The first energy data includes water, electricity, and heat instrument monitoring data of each process route. For example, the heat instrument monitoring data may be the data of heat energy generated by the fission reaction of nuclear fuel in the reactor pressure vessel (first process route); the water instrument monitoring data may be the data of energy converted from heat energy to steam in a loop. The electricity instrument monitoring data may be the data of energy converted from steam to mechanical energy and from mechanical energy to electrical energy. In some embodiments, the first energy data also includes gas instrument monitoring data.

[0078] The second equipment data includes the equipment on / off status, current and voltage data, and mechanical data detected by sensors installed on the equipment at historical moments. The second material data includes the measurement data of nuclear fuel in the nuclear fuel building at historical moments (loading amount, unloading amount, storage amount in the storage pool) and the distribution measurement data in the reactor pressure vessel. The second safety and environmental data includes the radiation monitoring data in and outside the containment building at historical moments, and the smoke monitoring data in each building. The second energy data includes the water, electricity, and heat instrument monitoring data of each process route at historical moments. In some embodiments, the second energy data also includes the gas instrument monitoring data of each process route at historical moments.

[0079] It should be noted that, on the one hand, the real-time measurement data and the historical statistical data differ in the time point of data collection; on the other hand, each historical statistical data also includes summary statistics of the real-time measurement data.

[0080] In addition, real-time measurement data and historical statistical data in workshop production can be set according to nuclear power process requirements and equipment operation requirements.

[0081] During implementation, each piece of data (real-time measurement data and historical statistical data) numbered for each device and each process route is numbered respectively to define the corresponding relationship between each device and each process route and the corresponding data.

[0082] S3. Through the digital twin method, the real-time measurement data and historical statistical data of the workshop production are mapped to the three-dimensional model of the workshop, forming a visual display model of workshop production management to guide production.

[0083] Here, the position of the real-time measurement data and historical statistical data in the three-dimensional modeling model can be determined according to the corresponding relationship between the real-time measurement data and the historical statistical data and the corresponding equipment or process route in the three-dimensional modeling model. For example, the real-time measurement data can be mapped to the three-dimensional modeling model according to the corresponding relationship between the real-time measurement data and the corresponding equipment or process route in the three-dimensional modeling model, and the actual situation of each equipment and each process route in the factory can be displayed in real time and intuitively. For example, according to the corresponding relationship between the historical statistical data and the corresponding equipment or process route in the three-dimensional modeling model, the historical statistical data can be connected in the three-dimensional model to realize the historical tracing of each equipment and each process route.

[0084] It should also be noted that the correspondence between the number of each device or process route and the real-time measurement data and historical statistical data can be constructed according to production requirements. In some other embodiments, the correspondence between each device or process route in the three-dimensional modeling model and the real-time measurement data and historical statistical data can also be constructed based on the correspondence between the devices, process routes and the real-time measurement data in the existing two-dimensional plan.

[0085] In some implementations, the real-time measurement data may also be used to drive the update of the 3D model, that is, to achieve a two-way mapping between the real-time measurement data and the 3D model.

[0086] In this embodiment, by acquiring the three-dimensional model of the workshop, acquiring the real-time measurement data and historical statistical data in the workshop production, and mapping the real-time measurement data and historical statistical data to the three-dimensional modeling model of the workshop through digital twins, an intuitive workshop production management visualization display model can be formed, which can realize a three-dimensional and intuitive presentation of the actual production conditions of each factory building, the equipment in each factory building, and the process routes of each equipment, thereby improving the timeliness of the workshop production management data.

[0087] In some embodiments, the historical statistical data is stored in a workshop production management subsystem.

[0088] Wherein, step S2 specifically includes:

[0089] S21. Obtain, from the workshop production management subsystem, a first correspondence between the factory building, the equipment in the factory building, the process route of the equipment and the real-time measurement data, and a second correspondence between the factory building, the equipment in the factory building, the process route of the equipment and the historical statistical data.

[0090] Here, a workshop production management subsystem is set in each factory building, which is a management system for workshop production presented in a two-dimensional plane. The workshop production management subsystem stores historical statistical data of each equipment and each process route in each factory building.

[0091] In some embodiments, the first corresponding relationship and the second corresponding relationship defined in the workshop production management subsystem may be defined according to production requirements. Specifically, the production requirements may be requirements for improving production efficiency and / or product quality requirements. For example, under the premise of improving production efficiency, data that can accurately describe the operating status of each device and the process route between each device.

[0092] The first relationship includes the correspondence between the equipment in the plant and the process route of the equipment and the real-time measurement data. During implementation, the first relationship is the correspondence between the number of the three-dimensional modeling model and the numbers of the first equipment data, the first material data, the first safety and environmental protection data, and the first energy data.

[0093] The defined second relationship may be a correspondence between the serial number of the three-dimensional model and the serial numbers of each of the second equipment data, the second material data, the second safety and environmental protection data, and the second energy data.

[0094] In some other embodiments, a first correspondence between the real-time measurement data and the three-dimensional modeling model can also be directly constructed, so that the real-time measurement data corresponding to the three-dimensional modeling model can be obtained according to the first correspondence, which can improve the accuracy of the display position of the real-time measurement data in the three-dimensional modeling model.

[0095] S22. According to the first corresponding relationship, obtain the real-time measurement data corresponding to each factory building, the equipment in the factory building, and the process route of the equipment.

[0096] Here, according to the first corresponding relationship, test sensors may be installed at corresponding positions of the workshop equipment to ensure accurate collection of real-time measurement data.

[0097] During implementation, the real-time measurement data corresponding to each factory building, the equipment in the factory building, and the process route of the equipment are directly obtained from the test sensors in each factory building through the corresponding real-time data acquisition interface in each factory building, so as to reduce the delay in obtaining real-time measurement data.

[0098] S23. According to the second corresponding relationship, historical statistical data corresponding to each factory building, the equipment in the factory building, and the process route of the equipment are obtained from the workshop production management subsystem.

[0099] Here, the second corresponding relationship includes a summary of the real-time measurement data collected according to the first corresponding relationship, and a corresponding relationship for statistical analysis based on the summarized data. For example, the second corresponding relationship includes the device status corresponding to the device at a historical moment, and the maintenance plan of the device.

[0100] Through the corresponding workshop production management subsystem data acquisition interface (the fourth information integration interface) in each factory building, historical statistical data corresponding to each factory building, the equipment in the factory building, and the process route of the equipment are obtained.

[0101] In some other embodiments, real-time measurement data is stored in the workshop production management subsystem in each factory building, and the fourth information integration interface can be used to obtain real-time measurement data and historical statistical data from the workshop production management subsystem in each factory building to reduce the amount of wiring in the data acquisition process and reduce costs.

[0102] In this embodiment, by defining the first corresponding relationship and the second corresponding relationship, obtaining real-time measurement data, and obtaining historical statistical data, real-time measurement data and historical statistical data corresponding to the equipment and process routes simulated by each three-dimensional modeling model can be obtained. By utilizing the first corresponding relationship and the second corresponding relationship defined in the workshop production management subsystem of the existing two-dimensional plan view, the definition process of the visualization display module can be simplified, the amount of calculation can be reduced, and the efficiency of workshop production management can be improved.

[0103] In some embodiments, the plant includes a production plant and a warehouse plant, the second correspondence includes a first sub-correspondence of equipment data in the plant, a second sub-correspondence of material data in the plant, a third sub-correspondence of safety and environmental protection data in the plant, and a fourth sub-correspondence of energy data of each device, step S23 specifically includes steps S231 to S234:

[0104] Step S231. According to the first sub-correspondence, obtain the second equipment data in the historical statistical data from the workshop production management subsystem, wherein the second equipment data includes the equipment data in the production plant and the measuring instrument data in each plant, wherein the equipment data in the production plant includes basic equipment information, equipment operating status and equipment maintenance plan data, and the measuring instrument data in each plant includes a measuring instrument ledger, a measuring instrument status and a measuring instrument inspection and maintenance data.

[0105] Here, the basic information of the equipment includes the equipment number in the workshop production management visualization display model to be formed. The equipment operation status includes the power on / off status, current and voltage data, and mechanical data detected by the equipment installation sensor (for example, the detection data of the control rod position in the control rod drive mechanism). The equipment maintenance plan data includes equipment maintenance records and maintenance plan forms.

[0106] The metering instrument ledger in the metering instrument data includes the instrument number in the workshop production management visualization display model to be formed. The metering instrument status is whether it is in use. The metering instrument inspection and maintenance data includes the metering instrument inspection and maintenance record and inspection and maintenance plan.

[0107] Step S232. According to the second sub-correspondence, obtain the second material data in the historical statistical data from the workshop production management subsystem, the material data including the material data in the production plant and the material data in the warehouse plant, the material data in the production plant includes the initial distribution of materials, material operations and material tracking, and the material data in the warehouse plant includes material inventory, material warehousing and material outbound delivery.

[0108] Here, material data includes the equipment numbers of various materials in the workshop production management visualization display model to be formed, as well as the initial distribution positions of various materials in the factory. Material operations include material operation records, real-time material tracking, and historical tracing. In this way, the real-time distribution of materials in various factory equipment can be realized.

[0109] The material data in the warehouse building may be the measurement data of the nuclear fuel in the nuclear fuel building (loading amount, unloading amount, storage amount in the storage pool).

[0110] Step S233. According to the third sub-correspondence, obtain second safety and environmental protection data in the historical statistical data from the workshop production management subsystem, where the second safety and environmental protection data includes safety and environmental protection test points, safety and environmental protection measured alarms, and safety and environmental protection statistical data.

[0111] Here, the safety and environmental testing points are the radiation monitoring data in and outside the containment plant, and the smoke monitoring data in each plant. The safety and environmental measured alarm is an alarm prompt when the radiation monitoring data exceeds the preset radiation threshold and the smoke monitoring data exceeds the preset smoke threshold. The safety and environmental statistical data can be the summary statistical data of historical alarm prompts.

[0112] Step S234. According to the fourth sub-correspondence, second energy data in the historical statistical data is obtained from the workshop production management subsystem, where the second energy data includes nuclear power energy measurement points, nuclear power energy performance and nuclear power energy balance.

[0113] Here, the nuclear power energy measurement point is the energy (water, electricity, heat) instrument monitoring point in the process route. The nuclear power energy performance is the summary measurement data of the water, electricity, and heat instrument monitoring data of each process route in the nuclear power plant at the historical moment. The nuclear power energy balance is the energy conversion situation in the energy process route.

[0114] In this embodiment, by acquiring the data of various equipment, materials, safety and environmental protection, and energy in the existing workshop production management subsystem and mapping the data into the three-dimensional model, the production status of various equipment, materials, etc. in the workshop can be viewed intuitively, thereby achieving a more intuitive historical tracing of the workshop production.

[0115] In some embodiments, the first equipment data represents the current operating status data of the nuclear power equipment, the first material data represents the current material distribution data, the first safety and environmental data represents the current safety and environmental alarm data, and the first energy data represents the current nuclear power energy performance.

[0116] Before step S23, step S2 further includes:

[0117] S230. The workshop production management subsystem obtains real-time measurement data through the first information integration interface to update historical statistical data.

[0118] Step S230 specifically includes steps S2301 to S2304:

[0119] Step S2301: Update the device operation status in the second device data according to the first device data.

[0120] Step S2302: Update material tracking in the second material data according to the first material data and material operation.

[0121] Step S2303: Update the safety and environmental protection measured alarm in the second safety and environmental protection data according to the first safety and environmental protection data.

[0122] Step S2304: Update the nuclear power energy performance in the second energy data according to the first energy data.

[0123] It is understandable that some historical statistical data in the workshop production management subsystem are updated in real time. Specifically, the equipment status information in the second equipment data can be, for example: on / off status, current and voltage data, and mechanical data detected by sensors installed on the equipment (for example, detection data of the position of the control rod in the control rod drive mechanism). The material tracking in the second material data is the real-time tracking of the position of the material in the workshop, which can be outside the equipment or inside the equipment. The safety and environmental measurement alarms in the second safety and environmental data, for example, alarm prompts when the radiation monitoring data exceeds the preset radiation threshold and the smoke monitoring data exceeds the preset smoke threshold. The nuclear power energy performance in the second energy data, for example, can be the summary measurement data of the water, electricity, and heat instrument monitoring data of each process route in the nuclear power plant at historical moments.

[0124] It should also be noted that the first information integration interface is a real-time data acquisition interface, which connects the workshop production management subsystem and the real-time monitoring equipment (sensor) to transmit the real-time measurement data to the existing workshop production management subsystem.

[0125] And / or, before step S2, the method further comprises step S20:

[0126] Step S20. The workshop production management subsystem obtains the quality inspection data and quality inspection results from the laboratory information management system through the second information integration interface, and updates the quality analysis data of the production products.

[0127] The Laboratory Information Management System (LIMS) integrates all types of laboratory information and data management processes. The quality inspection results in LIMS can assist the product quality management in the workshop production management subsystem to improve the production quality of products.

[0128] In this embodiment, through the update of the second equipment data, the second material data, the second safety and environmental data and the second energy data, the real-time measured first equipment data, the first material data, the first safety and environmental data and the first energy data can be respectively integrated into the historical statistical data in the workshop production management subsystem, thereby realizing the integration of real-time measurement data and historical statistical data in the workshop production management subsystem of each factory building, and providing support for the subsequent direct integration of real-time measurement data and historical statistical data into the three-dimensional modeling model.

[0129] In some embodiments, step S3 specifically includes steps S31 to S32:

[0130] Step S31. Based on the updated historical statistical data, the latest data of the historical statistical data is formed;

[0131] Step S32: Map the latest historical statistical data to the three-dimensional model of the workshop to form a visual display model of workshop production management.

[0132] Here, the latest data of historical statistics are the equipment operation status in the updated second equipment data, the material tracking in the second material data, the safety and environmental protection measured alarms in the second safety and environmental protection data, and the nuclear power energy performance in the second energy data.

[0133] During implementation, the latest data in the existing two-dimensional workshop production management subsystem is obtained to form the latest data of historical statistical data. Then, according to the correspondence between each equipment, each process route and the latest data in the workshop production management subsystem, the latest data is mapped to the three-dimensional modeling model of the workshop to form a visual display model of workshop production management.

[0134] In some other implementations, it is also possible to directly construct a corresponding mapping relationship between real-time measurement data and a three-dimensional modeling model. According to the mapping relationship, the real-time measurement data corresponding to the three-dimensional modeling model is obtained, and the real-time measurement data is mapped to the corresponding position in the three-dimensional modeling model to improve the accuracy of the real-time measurement data position display in the formed workshop production management visualization display model.

[0135] In this embodiment, by forming the latest data of historical statistical data and mapping the latest data of historical statistical data to the three-dimensional modeling model of the workshop, the update of historical statistical data is dispersed to the workshop production management subsystem in each factory building, and then the real-time measurement data and historical statistical data that have been integrated in the workshop production management subsystem are utilized, which can reduce the amount of calculation in the mapping process.

[0136] In some embodiments, the second correspondence further includes a fifth sub-correspondence of the production plan and a sixth sub-correspondence of the maintenance plan, and step S23 further includes steps S235 to S236:

[0137] Step S235. According to the fifth sub-correspondence, the production plan data in the historical statistical data is obtained from the workshop production management subsystem, and the production plan data includes pre-compiled production plan, released production plan, and adjusted production plan.

[0138] Here, the pre-compiled production plan can be an operation plan for nuclear power production. The launch production plan is a launch nuclear fuel production plan. Adjusting the production plan to a changed operation plan can be a change in the launch plan or a change in production demand.

[0139] Step S236. According to the sixth sub-correspondence, the maintenance plan data in the historical statistical data is obtained from the workshop production management subsystem, where the maintenance plan data includes equipment status and equipment maintenance plan.

[0140] Here, the maintenance plan data includes equipment status and equipment maintenance plan. In some embodiments, the maintenance plan also includes an appliance maintenance plan.

[0141] In this embodiment, by acquiring the production plan data and maintenance plan data in the existing workshop production management subsystem, the production plan data and maintenance plan data can be directly presented in the subsequent workshop production management visualization display model, realizing three-dimensional visualization traceability of the production plan and equipment maintenance of the workshop production.

[0142] In some embodiments, step S3 further includes steps S33 to S34:

[0143] Step S33. Call the workshop production management subsystem function interface through the third information integration interface;

[0144] Step S34. Generate a human-computer interaction of the workshop production management visualization display model according to the functional interface of the workshop production management subsystem.

[0145] Here, the workshop production management subsystem also stores a functional interface to realize the human-computer interaction of the workshop production process. During implementation, the workshop production management subsystem functional interface in each factory building is called through the third information integration interface (workshop production management system function / interface).

[0146] In some other implementations, the human-computer interaction function can be directly built in the workshop production management visualization display model to improve the personalized setting of the human-computer interaction function in the workshop production management visualization display model.

[0147] In this embodiment, the human-computer interaction function of the workshop production management visualization model is realized by calling the workshop production management subsystem function interface and generating the human-computer interaction of the workshop production management visualization display model. The existing workshop production management subsystem function interface is utilized to simplify the generation process of the human-computer interaction function and improve the generation efficiency of the human-computer interaction function.

[0148] Embodiment 2:

[0149] The specific implementation process of the above method is described below in conjunction with specific application examples. Figure 2 As shown, the application system of the workshop production management method based on digital twin technology includes: a workshop production management system (workshop production management subsystem), a workshop production management module based on digital twin, and an information integration interface.

[0150] Specifically, the workshop production management system includes: planning management, material management, warehouse management, equipment management, measuring instrument management, safety and environmental management, energy management, and quality management modules.

[0151] Among them, the production plan management module is used to realize plan preparation, plan delivery, plan adjustment, plan viewing and statistical analysis; the material management module is used to realize material operation, material distribution and material tracking; the warehouse management module is used to realize inventory location, material warehousing and outbound delivery, and material inventory management; the equipment management module is used to realize equipment ledger, equipment basic information, equipment status, and equipment maintenance plan management; the measuring instrument management module is used to realize measuring instrument ledger, measuring instrument status, and measuring instrument inspection and maintenance management; the energy management module is used to realize energy measurement points, energy performance, energy balance, energy settlement, and energy comprehensive statistical analysis management; the safety and environmental management module is used to realize safety and environmental measurement points, safety and environmental measurement alarms, and safety and environmental statistical analysis management; the quality management module is used to realize integration with the laboratory information management system (Laboratory Information Management System, LIMS) to realize quality data management and quality data statistical analysis.

[0152] The workshop production management module based on digital twins includes: workshop 3D modeling and workshop production management based on digital twin technology. Among them, the 3D modeling module is used to realize workshop production lines, key equipment, process steps and flow modeling; the workshop production management based on digital twins is used to realize the functions and interface calls of the workshop production management system, material distribution and tracking, equipment status, storage status, energy status, safety and environmental status, and quality status in 3D real-time display.

[0153] The information integration interface includes: a real-time data acquisition interface (first information integration interface), a workshop production management system function / interface calling interface (third information integration interface) and a workshop production data calling interface (fourth information integration interface).

[0154] Among them, through the real-time data acquisition interface, it is possible to obtain real-time monitoring data of equipment (such as whether the equipment is turned on or off, current and voltage data, equipment installation sensor detection data, etc.), real-time safety and environmental monitoring data (such as smoke monitoring data, radiation monitoring data, etc.), real-time energy monitoring data (such as water, electricity, gas and heat instrument monitoring data at each node), and real-time material location monitoring data. For the above real-time data, on the one hand, by establishing an association between the three-dimensional model and the acquisition node in the digital twin platform, the real-time situation display based on real-time data and three-dimensional model can be realized; on the other hand, the real-time data collected by each node is uniformly included in the workshop production management system for unified record management. Based on the workshop production management system management data, various data statistical analysis, data traceability, data prediction and other functions can be realized. Through the workshop production management system related function / interface call interface, users can call the workshop production management system related system functions and system interfaces to meet the needs of human-computer interaction operations.

[0155] Through the data acquisition interface of the workshop production management system, the current location and historical flow and change data of materials related to the workshop production management system, the current situation of storage and historical in and out data, the current situation of equipment and historical maintenance data, the current situation of safety and environmental protection and historical monitoring data, the current monitoring of energy and historical cumulative data can be obtained. Based on the above data, users can display and analyze the historical flow of selected batches of materials through workstations and changes, equipment inspection and maintenance history and subsequent inspection and maintenance plans, historical alarm information of each measuring point, and various types of energy cumulative consumption information in the digital twin system visualization display module. In addition, through the workshop production data call interface, the workshop management data (including real-time data and historical data) can be called, and historical data analysis or trend prediction can be performed based on the data.

[0156] The workshop production management system function / interface calling interface is used to call the user interaction interface related to workshop production management.

[0157] Through the LIMS experiment data acquisition interface, it is possible to obtain relevant quality inspection data and quality monitoring result data in the LIMS experiment management system, and incorporate them into the workshop production management system for unified management. In addition, combined with the three-dimensional visualization model, it is possible to realize information reminders on the inspection results of different material batches at different inspection stations.

[0158] like Figure 3 As shown, an application embodiment of the workshop production management method based on digital twin technology includes steps 100 to 600:

[0159] Step S100: Construct a three-dimensional model of the workshop building, key equipment, process flow, and process steps.

[0160] Step S200. Based on the actual production management, the production plan is compiled, issued, executed and feedback is provided in the production management system.

[0161] Step S300. In combination with actual production management, the distribution and operation status of each material is input into the production management system in real time, and combined with the three-dimensional model, the real-time distribution status of materials at each workstation is realized.

[0162] Step S400. By acquiring the material in and out operation records of the production management system in real time, the material storage information is updated in time, and combined with the three-dimensional model, the storage information is displayed in real time.

[0163] Step S500. Obtain equipment, safety and environmental protection, and energy monitoring data through a real-time database, and combine it with a three-dimensional model to achieve real-time display of equipment, safety and environmental protection, and energy situation information.

[0164] Step S600: Real-time display of quality status is achieved by acquiring quality management information of the production management system in real time and combining it with a three-dimensional model.

[0165] Here, data mapping can be achieved through identifier matching technology. Specifically, by assigning unique identifiers to the collected data and elements in the 3D model, the points obtained from the control system are mapped to the corresponding 3D model motion axes, and the model's motion mode and origin offset are set, so that the model movement is driven by data and the effect of mapping the production process is achieved.

[0166] In addition, if Figure 4 As shown, a system deployment structure diagram of a workshop production management method based on digital twin technology provided by an embodiment of the present invention, the system deployment architecture mainly includes an application server, a database server and a client device. Among them, the application server is mainly used to deploy relevant application programs of each workshop production management system, the data server mainly realizes the unified management of the real-time production process (such as equipment status information, safety and environmental monitoring information, energy monitoring information, etc.) and the data of each workshop production management system (such as production planning, operation management, material management, warehouse management, measuring instrument management, quality management, etc.), and the client device mainly realizes the visualization display of workshop production management based on three-dimensional models and human-computer interaction operation.

[0167] It is understandable that the client in each plant is used to perform visualization and human-computer interaction, and also integrates the acquired data and the acquired 3D model (maps the data into the 3D model). In some embodiments, the workshop production management visualization display model of each plant in each client can also be integrated in the main control room to form a workshop production management visualization display model of the entire nuclear power plant.

[0168] It should also be noted that the workshop production management system functions / interfaces are obtained from the application server, and the workshop production management system data is obtained from the database server. The workshop production management system is distributed in two servers in the system deployment diagram.

[0169] In this embodiment, through three-dimensional modeling of the workshop, an intuitive display of key equipment and key process flows in the workshop production can be achieved. Through the construction of a production management system, unified and standardized management of production plans, material operations, material warehousing, equipment information, measuring instrument information, safety and environmental protection information, energy information, and quality information related to workshop production management can be achieved. On this basis, through information integration, a digital twin display of material distribution, material warehousing status, equipment status, safety and environmental protection situation, energy performance, and quality situation information based on the three-dimensional model can be achieved, thereby enhancing the visibility of workshop management.
