Description

Technical Field

[0001] The present invention relates to the technical field of intelligent management of blind plates, and in particular to an intelligent blind plate configuration analysis system and method based on three-dimensional model analysis. Background Art

[0002] The formal name of the blind plate is flange cover, also called blind flange or pipe plug. It is a flange without a hole in the middle, used to block the pipe opening.

[0003] In the system equipment of petrochemical industry, the connection relationship between process pipelines and equipment, instruments and valves is intricate. Valves as process material cut-off devices cannot completely isolate materials. Therefore, when equipment and pipelines are inspected and repaired, blind plates are the most effective means of material isolation. By installing blind plates, dangerous materials can be prevented from entering the construction space during the process of opening fire and entering confined space operations, avoiding accidents such as fire, explosion, poisoning, and suffocation. During equipment inspection, shutdown, renovation and expansion, emergency treatment, etc., many operating parts must isolate materials. Setting blind plates is the only effective and must-implement safety measure.

[0004] In the existing production operations, blind plate planning is required before construction, so that blind plates are set at the most appropriate positions to achieve effective setting of blind plates and avoid invalid setting of blind plates. Blind plate planning starts from the operation point, diverges outward, and exhausts the equipment and pipelines connected to it. If a branch is encountered, continue to exhaustively enumerate until a flange (valve) on which a blind plate can be installed is found. In actual work, the steps of blind plate planning include: first, find the blind plate installation position on the process flow chart, adjust it in combination with the site conditions, installation convenience, production status, and material status, and finally form a complete set of blind plate solutions including blind plate installation position, material emptying plan, blind plate specifications and models, and blind plate disassembly and assembly closed-loop management. However, the formation process of the existing blind plate planning scheme requires a long time for manual planning, and planning errors are prone to occur when planning through the blind plate plane plan, so it does not have an ideal isolation effect. At present, the research and development of the required technology focuses on the research and development of the specific structure of the blind plate, and there is no system that can automatically perform blind plate configuration analysis. Therefore, it is impossible to quickly propose a blind plate planning scheme through system calculation and analysis, and it is also impossible to effectively improve the work efficiency of blind plate planning.

[0005] For example, Chinese patent document CN102518905B discloses a management system for blind plates with sensor units and smart electronic tags, specifically, a sensor unit and a smart electronic tag are set on the blind plate, the sensor unit detects the properties of the medium in the closed pipeline, and the receiving and reading unit sends corresponding instructions to the smart electronic tag, requiring the smart electronic tag to detect the sensor unit, read and write data, and transmit data according to the instructions, and transmit the information about the blind plate stored in the smart electronic tag to the receiving and reading unit through wireless or wired transmission, so as to realize intelligent control and monitoring. However, the invention is used to solve the problem of blind plate monitoring and collecting pipeline data, and is based on blind plate planning, that is, the invention does not improve the steps of blind plate planning, and therefore does not improve the efficiency of blind plate planning.

[0006] Therefore, how to determine the best location for setting blind plates through intelligent analysis, so as to obtain the best blind plate planning scheme and implement it, is a difficult problem that has always existed in the current technical field.

[0007] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0008] In view of the shortcomings of the prior art, the present invention provides an intelligent blind plate configuration analysis method based on three-dimensional model analysis, the method at least comprising:

[0011] The selected blind plate configuration position is merged with the three-dimensional model and displayed with a visible position identifier.

[0012] The present invention overcomes the defects of traditional blind plate configuration schemes that rely on manual analysis, resulting in long scheme generation time and unreasonable management. The present invention uses a three-dimensional model to quickly obtain information such as equipment, materials, and space related to blind plate configuration, so that the blind plate configuration position can be automatically selected according to the strategy and a reasonable blind plate configuration scheme can be generated, saving time for manual blind plate planning.

[0018] Preferably, the method further comprises: displaying the pipeline topology relationship associated with the position information of the operation point and / or the blind plate configuration in a manner that can be distinguished from the display part of the three-dimensional model. When the user views the three-dimensional model, the operation point, the blind plate configuration position, and the pipeline topology relationship can be quickly determined through the distinguished features, so that the blind plate configuration information can be viewed in a targeted manner instead of viewing invalid display information, thereby improving the efficiency of the user viewing the three-dimensional model.

[0037] The following is a detailed description with reference to the accompanying drawings.

[0038] The present invention provides an intelligent blind plate configuration analysis system and method based on three-dimensional model analysis. The present invention also provides a blind plate configuration analysis display terminal and server. The present invention also provides a storage medium for storing the intelligent blind plate configuration analysis method based on three-dimensional model analysis.

[0039] In the existing process, it is necessary to manually plan the blind plate configuration through the equipment drawings and form a blind plate configuration plan. In the process of manual planning, the basic principle of blind plate configuration is: starting from the operation point, diverging outward, exhaustively enumerating the equipment and pipelines connected to it, and if encountering a branch, continue to exhaustively enumerate until a flange (valve) on which the blind plate can be installed is found. However, due to the limited manual computing ability, for equipment with a large system and complex pipeline distribution, the calculation efficiency of the manual analysis of the blind plate configuration is slow, and it is easy to make calculation errors, which makes the material isolation effect after the blind plate is set unsatisfactory. In addition, for equipment with a large system, each production process and material transmission affect each other. When installing the blind plate, it is necessary to arrange and adjust the pipelines, material transmission, emptying and other tasks associated with the blind plate installation in order to achieve the orderly configuration and installation of the blind plate. In reality, due to the unreasonable manual arrangement of workers and managers, the time for blind plate configuration and blind plate replacement is relatively long, and the time between each link is also long, which undoubtedly delays the production efficiency and transportation efficiency of the factory. Therefore, how to quickly obtain a reasonably arranged blind plate configuration plan so that the system equipment can complete the blind plate configuration in a shorter time, reduce the impact of the blind plate configuration on the overall production, and make the blind plate configuration effect better is a difficult technical problem to solve.

[0040] The present invention hopes to analyze the blind plate configuration according to the three-dimensional model of the system equipment, and quickly obtain the blind plate configuration plan with the help of the super computing power of the computer, so as to arrange the various steps of the blind plate configuration in an orderly manner, improve the efficiency of blind plate replacement, and reduce the impact on the production of large equipment. At the same time, the present invention hopes to obtain the best blind plate configuration position according to the blind plate configuration plan, thereby improving the effect of the blind plate configuration.

[0041] The intelligent blind plate configuration analysis system based on three-dimensional model analysis of the present invention includes at least one processor. The processor at least includes:

[0042] A reading unit, used for reading the pipeline topology relationship and / or production material information of the three-dimensional model;

[0043] An analysis unit is used to determine at least one blind plate configuration position based on the operation information and the pipeline topology relationship in the three-dimensional model; and select at least one blind plate configuration position based on the production information in the three-dimensional model including at least process, equipment, material and / or space;

[0044] At least one terminal displays the selected blind plate configuration position as a visible position identifier.

[0045] Preferably, the intelligent blind plate configuration analysis system based on three-dimensional model analysis also includes a storage unit for storing the three-dimensional model of the production equipment, the pipeline topology relationship and / or the production material information. The storage unit establishes an information transmission relationship with the reading unit and the analysis unit in a wired and / or wireless manner.

[0046] The reading unit and the analyzing unit establish an information transmission relationship in a wired and / or wireless manner.

[0047] The reading unit is a data processor with the function of collecting and selecting pipeline topological relationship and / or production material information, and the data processor is, for example, one or more of a dedicated integrated chip, a processor, a microprocessor, and a logic processor.

[0048] The analysis unit is a data processor capable of data calculation and information analysis according to a preset calculation logic, and the data processor is, for example, one or more of a dedicated integrated chip, a processor, a microprocessor, and a logic processor.

[0049] The reading unit and the analyzing unit can be integrated into one processor, or can be connected to form a large processor.

[0050] At least one terminal establishes an information transmission relationship with the processor in a wired and / or wireless manner. The terminal is an electronic device with a display function, which can be a non-movable terminal or a portable terminal. Non-movable terminals are, for example, computers, service center system terminals, etc. Portable terminals are, for example, smart phones, portable computers, tablet computers, smart bracelets, smart watches, VR (virtual reality) terminals, etc.

[0051] The specific method for the analysis unit to analyze and generate a blind plate configuration plan is as follows.

[0052] Figure 1 The two-dimensional model of the topological relationship of the pipeline in the partial area. The topological relationship of the pipeline in the present invention refers to the topological connection relationship between the driving device, the pipeline, and the valve. In the two-dimensional model display interface of the terminal, multiple first position identifiers 1 capable of blind plate configuration are displayed.

[0053] Figure 2 The 3D model is a topological model of the pipelines in some areas. The 3D model and intelligent P&ID not only contain information such as processes, equipment, materials, and space, but also include the topological connection relationship between drive equipment, pipelines, and valves. In the 3D model display interface of the terminal, multiple second position identifiers 2 that can be configured with blind plates are displayed.

[0054] The analyzing unit determines the location information of at least one blind plate configuration in an exhaustive manner based on the location information of the operation point sent by the terminal and the pipeline topology relationship and / or production material information of the three-dimensional model sent by the reading unit, and sends the location information to the terminal in a manner of being fused with the three-dimensional model, such as Figure 2 The analysis unit searches for all positions where blind plates can be added in sequence according to the connection relationship until all blind plates are added.

[0055] The specific analysis steps of the analysis unit are as follows.

[0056] The analysis unit determines the first-level position of the pipeline connected to the operating point based on the operating point. The first-level position is the flange position of the inlet and outlet directly connected to the operating point. Setting a blind plate at the first-level position can isolate the operating point from the system.

[0057] In the case where the operation point is associated with material flow, the analysis unit determines the feeding pipeline that transports the material to the operation point based on the material information related to the operation point, and exhaustively enumerates all the second-level positions closest to the first-level position in a manner opposite to the material transportation direction. Blind plates are set at the second-level positions to prevent materials from being transported to the first-level positions.

[0058] In the case of leakage at the flange of the second-stage position, all third-stage positions closest to the second-stage position are exhaustively enumerated in the opposite direction of the material conveying direction. Blind plates are set at the third-stage positions.

[0059] In the case of leakage at the flange of the third-stage position, all the fourth-stage positions closest to the third-stage position are exhaustively enumerated in the opposite direction of the material conveying direction. Blind plates are set at the fourth-stage positions.

[0060] Repeat this process in reverse order until the operation point and the materials associated with the operation point are isolated from the entire system.

[0061] Preferably, if there is a multi-way connecting valve in the process of reverse exhaustion from the Nth level position, multiple flanges of the multi-way connecting valve that do not directly transport materials are marked as the N+1th level position. A blind plate is set at the N+1th level position.

[0062] For example, Figure 1 The pump has a problem and needs to be isolated from the system. The pump position is the operation point. The pump inlet and outlet flanges are the first-stage position. First, add a blind plate to the pump inlet and outlet flanges, i.e., the first-stage position. Because the first-stage position needs to be in direct contact with the material, the flange needs to be disassembled when adding the blind plate, which will cause material leakage. Therefore, from the first-stage position, reverse along the material conveying direction of the pump to the closest flange, i.e., the second-stage position. Add a blind plate at the second-stage position.

[0063] If there is leakage at the second-stage flange, find the closest flange in the opposite direction of the material being transported by the pump, that is, the third-stage flange, remove the flange and add a blind plate. Repeat this process in reverse order until the entire pump and the material inside it are isolated from the entire system.

[0064] If a three-way pipe appears during the reverse exhaustive process, blind plates need to be added to the other two flanges of the three-way pipe to isolate the three-way pipe from the system.

[0065] Preferably, the analysis unit is selected at the rear flange of the valve where the material comes from as the location for adding a blind plate. When adding a blind plate, both sides of the blind plate should have gaskets and be tightened with bolts to maintain its tightness.

[0066] Preferably, the processor further comprises a graphics processing unit for integrating the selected blind plate configuration position with the three-dimensional model and displaying the position with a visible position identifier.

[0067] Preferably, the graphics processing unit is also used to distinguishably display the contents related to the blind plate configuration in the three-dimensional model to avoid mixing the displayed contents with the contents of the three-dimensional model itself, which would result in the user being unable to quickly view effective information.

[0068] Preferably, the graphics processing unit is configured to display the pipeline topological relationship associated with the position information of the operation point and / or the blind plate configuration in a manner that can be distinguished from the three-dimensional model.

[0069] Preferably, the graphics processing unit is configured to display the position information of the blind plate configuration as at least one position identifier that can be distinguished from the three-dimensional model, wherein the position identifier can be distinguished from the three-dimensional model at least in terms of color, brightness and / or contrast.

[0070] Preferably, the graphics processing unit is configured such that: when the virtual display device displays, the position identifier can indicate the blind plate configuration position in a suspended manner.

[0071] Preferably, the graphics processing unit is configured such that, in the three-dimensional model, when the second position identifier is selected, the material adjustment information related to the position indicated by the second position identifier is displayed in a manner of partially overlapping with the three-dimensional model.

[0072] Preferably, in response to the display dimension switching instruction information sent by the terminal, the graphics processing unit converts the three-dimensional model into a two-dimensional model, and merges the blind plate configuration position information with the two-dimensional model and sends it to the terminal for display.

[0073] Preferably, the processor also includes a machine learning unit for learning the blind plate configuration scheme and updating and optimizing the blind plate configuration scheme.

[0074] Specifically, when the three-dimensional model changes, the analysis unit determines the location information of at least one blind plate configuration in an exhaustive manner based on the pipeline topology relationship and / or production material information in the model sent by the reading unit, and sends the location information to the terminal in a manner integrated with the three-dimensional model.

[0075] Preferably, when the operator views the configuration scheme of the blind plate by wearing a VR display device, the three-dimensional model is displayed in a virtual three-dimensional space. The operation point is displayed in a first color or a first identifier. The first-level position is displayed in a second color or a first identifier. The second-level position is displayed in a third color or a third identifier, so that the operator can quickly know the blind plate partition position and the corresponding partition device in the virtual three-dimensional space.

[0076] For example, the first color is a prominent red. The second color is less conspicuous than the first color. The third color is less conspicuous than the second color. Preferably, the second color is displayed in a flashing manner. The third color is displayed in a flashing manner. In this way, each level of position is displayed with a different identifier, which facilitates the operator to quickly identify the location of the blind plate and the replacement order.

[0077] Preferably, in a virtual reality environment, in response to a click operation on the identifier of the position of the blind plate that needs to be configured, a blind plate replacement suggestion table for the blind plate configuration position is displayed. The blind plate replacement suggestion table can be set in a suspended manner at any position in the virtual display environment. Preferably, the information in the blind plate replacement suggestion table includes at least information such as blind plate specifications, blind plate replacement time, and blind plate replacement operator. Preferably, the blind plate replacement suggestion table is not limited to being displayed in the form of a table, but can also be displayed near the blind plate configuration position in the form of a three-dimensional model pattern of the blind plate to be installed. Such a setting prevents operators from quickly understanding the size, specification, model and other information of the blind plate to be installed, thereby reducing the error mode of blind plate installation.

[0078] Preferably, a recommended installation time is set next to the three-dimensional model pattern of the blind plate to avoid the situation where the operator chooses an inappropriate installation time and causes losses to the production system, thereby ensuring the orderly operation of the production system and minimizing losses caused by maintenance of the production system.

[0079] Preferably, in response to the position information of the installer who installs the blind plate, the analysis unit displays sequence information at the blind plate configuration position based on the delivery conditions of the material information, so that the installer can carry out construction in an orderly manner and avoid disorderly operation by the installer.

[0080] Preferably, the analysis unit requests the control module of the production system for material input rule information related to the pipeline in the blind plate configuration scheme, and the analysis unit determines the time to suspend material input based on the material input rule information, the first time required for the material to be transported from the last-level position to the first-level position, and the second time required for workers to install all blind plates.

[0081] Specifically, the analysis unit selects the installation time period information of at least one blind plate configuration scheme based on the material input regularity information and sends it to the terminal connected thereto. When the terminal feeds back the selected installation time period information to the analysis unit, the analysis unit configures the material pause time related to the pipeline where the blind plate needs to be installed. The material pause time is preferably selected as the interval time between two material delivery.

[0082] The first time required for the unit material to arrive and be transported from the last position to the first position is analyzed to determine the pause time of the material input. The pause time is not less than the time length of the first time. The pause time also includes the predicted second time. For example, the pause time ≥ the first time + the second time.

[0083] The analysis unit configures a second time for installing all blind plates based on the time for workers to install a single blind plate and the current number of maintenance personnel. For example, the first pipeline segment is located upstream of the second pipeline segment and connected in series, and the material of the entire related pipeline needs to be emptied before construction. There are currently two maintenance workers. The analysis unit divides two groups of work points based on the area of ​​the work points where the blind plates need to be installed so that two maintenance workers can work at the same time.

[0084] For example, the first pipeline segment is connected in parallel with the second pipeline segment, and the analysis unit predicts the first emptying time of the first pipeline segment and the second emptying time of the second pipeline segment based on the IoT transmission law of daily production. The analysis unit arranges the installation sequence and synchronous construction time of the blind plates at the two pipeline operation points according to the first emptying time and the second emptying time of the second pipeline segment.

[0085] The analysis unit sends the selected material pause moment, pause duration, first time, and second time to the terminal for manual adjustment and confirmation.

[0086] After the analysis unit receives the construction time plan fed back by the terminal, the analysis unit sends the material pause time, pause duration, first time, and second time to the control module that controls the production system. Based on the received material pause time, pause duration, first time, and second time, the control module pauses the material conveying device at a preset time to achieve the suspension of material input.

[0087] After the material pause time reaches the pause time, the analysis unit sends information on whether to run to at least one terminal. In response to the information on whether to run, the terminal module sends an instruction of "continue to pause" or "run" to the control module.

[0088] Preferably, the pipelines of the factory system are complicated, and maintenance workers often find the working points quickly and accurately. They often spend a lot of time in confirming the relevant pipelines and the accurate location of the working points. Instead, they spend less time installing blind plates.

[0089] When the construction worker wears the virtual reality device, the analysis unit receives the positioning signal sent by the positioning component in the virtual display device. The graphics processing unit receives the positioning signal and displays the route for the maintenance worker to reach the target work point so that the maintenance worker can quickly reach the work point. When the image processing unit confirms that the maintenance worker has arrived at the work point, the image processing unit can also add an identifier to the work point so that the maintenance worker can quickly confirm the location where the blind plate needs to be replaced.

[0090] The valves of most pipelines are similar. How to avoid the problem of maintenance personnel selecting the wrong valve and installing blind plates is a further issue that needs to be solved.

[0091] Preferably, in order to ensure the correctness of the confirmation of the working point, the present invention cross-confirms the image processing unit with the manually marked markers to avoid the maintenance personnel from selecting the wrong working point due to lack of concentration or certain interference factors.

[0092] The storage unit stores the marking information corresponding to each valve. The marking information at least includes content displayed in the form of pictures, videos and / or text information. Preferably, the marking information is information that can be collected by a person or an image acquisition device when in the installed state, such as the code and type on the preset number plate, which can determine the unique identity of the operating point. These marking information are all manually confirmed and stored in the storage unit.

[0093] When the image processing unit confirms that the maintenance personnel have arrived at the work point, the image processing unit sends a request message for collecting mark information to the virtual reality device with a communication connection. After receiving the mark information collected by the maintenance personnel through the image acquisition component of the virtual reality device, such as a camera. The image processing unit sends the stored mark information and the uploaded new mark information to the analysis unit for comparison. When the two mark information are consistent, the image processing unit responds to the "information is consistent" instruction fed back by the analysis unit and sends the "valve confirmed correct" message to the virtual reality device. At the same time, when the analysis unit compares the two mark information and obtains the comparison result of "information is consistent", it defaults to the maintenance personnel starting to replace the blind plate and starts recording the replacement time of the blind plate.

[0094] The analysis unit sends the maintenance personnel's replacement time for the blind plate to the storage unit for use in making a final performance evaluation of the maintenance personnel's maintenance time and maintenance volume.

[0095] Preferably, when the two marking information are inconsistent, the image processing unit sends a message of "incorrect valve confirmation" to the virtual reality device in response to the "information is inconsistent" instruction fed back by the analysis unit. The maintenance personnel need to continue to find the working point according to the instructions of the identifier and confirm the working point again. This is repeated until the maintenance personnel finds the accurate working point and uploads the latest marking information through the virtual display device. When the analysis unit compares the two marking information and obtains the comparison result of "information is consistent", it is assumed that the maintenance personnel starts to replace the blind plate and starts to record the replacement time of the blind plate.
