[0030] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0031] The prior art (CN112871703A) relates to the field of intelligent coal preparation technology, and in particular to an intelligent coal preparation management platform and method thereof. The intelligent coal preparation system includes an API module, an industrial big data module, an industrial gateway module, an algorithm engine module, an industrial vision module, a platform push module, a basic service module, an edge computing module and a digital twin module. The present invention can collect and compare images of coal bodies on a conveyor belt. If there are coal bodies (coal gangue) that do not meet the standards in the coal body, they will be sorted out from the coal body by a sorting robot. The present invention can correct the coal body images collected by the video terminal, and can effectively improve the accuracy of coal body identification. The present invention can realize the intelligent operation of processes such as precise coal separation, equipment health management, safety assurance, and business management through the deep integration of intelligent coal preparation and big data, which is of great significance to improving the level of coal preparation production safety and ensuring a stable supply of coal.

[0032] It can be seen that the prior art (CN112871703A) proposes an intelligent coal preparation method, in which the digital twin module can realize the development of process models, equipment models, analysis models and knowledge base models. However, the application field of the prior art (CN112871703A) is different from that of the present invention, and the prior art (CN112871703A) does not disclose the digital twinning of the vibrating screen used for drilling.

[0033] The prior art (WO2020072720A1) provides a method that may include: receiving time series data acquired during equipment operation at multiple natural resource sites; and detecting operation events using the time series data; ranking the operation events; associating each operation event with a corresponding operation action; and outputting at least a portion of the sorted operation events, each event having its corresponding operation action.

[0034] It can be seen that although the prior art (WO2020072720A1) is applied to the oilfield system, the prior art (WO2020072720A1) does not apply the digital twin technology to digitize the vibrating screen.

[0035] Prior art (WO2021019551A1) generally relates to methods and systems for real-time automatic optimization of manufacturing operations and systems. In general, the behavior of a manufacturing plant changes over time due to the effects of speed or equipment aging. Subsequently, the optimization configuration of the installation must be modified to adapt it to the current behavior of the installation. The disclosed system identifies changes in the behavior of the installation by monitoring disturbance variables and installation KPIs. Once the changes in the installation exceed quantitative critical limits in terms of disturbance changes and process variables and key performance indicators, the current optimization problem is considered no longer valid, and the system triggers automatic optimization of the installation. The system configures a new optimization problem taking into account prior knowledge of the problem formulation and current installation conditions.

[0036] It can be seen that the prior art (WO2021019551A1) involves the concept of digital twins, and the prior art (WO2021019551A1) points out the digital twins of smart environments or factories. However, the prior art (WO2021019551A1) does not further point out that a vibrating screen for drilling can be digitally twinned, nor does it disclose a specific method for digitally twinning a vibrating screen.

[0037] In view of the above-mentioned defects of the prior art, the present invention constructs a digital twin mapping model through a vibrating screen entity, and the digital twin is connected to the device entity through the digital twin mapping model; the sensor is installed on the vibrating screen, connected to the device through a data interface, and the digital twin mapping model is used to collect relevant data and parse the protocol. The present invention realizes the virtual-real interaction of the vibrating screen device entity in the digital space, which helps to improve the inherent safety of the vibrating screen. The present invention realizes the digital twin of the vibrating screen, which can diagnose and predict equipment faults, optimize the production process, and monitor the quality of the product in real time.

[0038] Figure 1 A flowchart of the steps of a digital twin method of a drilling vibrating screen according to an embodiment of the present invention is shown.

[0039] like Figure 1 As shown, in step S101, according to the structural characteristics of the drilling vibrating screen, a vibrating screen static model including a supporting system static model, a screening system static model, and a conveying system static model is constructed.

[0040] In one embodiment, in step S101, the static model of the support system includes but is not limited to: the static model of the base and the frame. The static model of the screening system includes but is not limited to: the static model of the screen box, the static model of the screen vibration isolation spring and the exciter.

[0041] In one embodiment, in step S101, a static model of a vibrating screen including a static model of a supporting system, a static model of a screening system, and a static model of a conveying system is constructed by the following steps: three-dimensional geometric modeling of the system is performed based on entities of the target system, and the appearance, shape, proportion, and structure of the target system are restored to obtain a static model of the vibrating screen.

[0042] Furthermore, the static model of the vibrating screen is consistent with the basic identity information of the target vibrating screen, wherein the basic identity information includes but is not limited to: model, name, models of each core component and specifications of the core components.

[0043] like Figure 1 As shown, in step S102, based on the static model of the vibrating screen, the real-time drilling production data during the drilling process and the real-time vibrating screen operation data are accessed to build a vibrating screen database.

[0044] In one embodiment, in step S102, the real-time drilling production data includes but is not limited to: daily drilling report, real-time data of mud logger, and intelligent monitoring data of well control.

[0045] In one embodiment, in step S102, the real-time operation data of the vibrating screen includes but is not limited to: screen surface inclination angle, vibration direction angle, screen surface amplitude, vibration times, and material movement speed.

[0046] like Figure 1 As shown, in step S103, the static model of the vibrating screen is data-driven according to the real-time drilling production data and the real-time vibrating screen operation data to obtain a digital twin model of the vibrating screen that is synchronized with the real-time drilling process.

[0047] In one embodiment, in step S103, the static model of the vibrating screen is data-driven through the following steps: comprehensively analyzing the logical association between the real-time drilling production data and the real-time vibrating screen operation data, forming a multivariable algorithm model, decomposing the actions of each system under different working conditions, forming a correspondence, and realizing the triggering of target system actions under the conditions of changes in the real-time drilling production data and the real-time vibrating screen operation data.

[0048] In one embodiment, a digital twin method for a vibrating screen for drilling further includes: based on the digital twin model of the vibrating screen, performing model rendering, realizing two-dimensional charts and three-dimensional roaming effect display.

[0049] Specifically, based on modeling and data-driven, the synthesis of the overall twin of the vibrating screen is formed to achieve the development of effects such as model rendering, two-dimensional charts and roaming.

[0050] In one embodiment, a digital twin method for a vibrating screen for drilling further includes: for the digital twin model of the vibrating screen, by replacing the system model and performing different data access operations, rapid replication of models of different models and manufacturers is achieved.

[0051] Specifically, based on the digital twin model that has been built, rapid replication of different vibrating screen models can be achieved through operations such as equipment model replacement and data access.

[0052] The present invention constructs a device entity (vibrating screen), a digital twin and a digital twin mapping model. The digital twin is connected to the device entity through the digital twin mapping model. The sensor is installed on the device entity and connected to the device through a data interface. The digital twin mapping model is used to collect relevant data and parse the protocol. The modeling and data interaction of the device entity in the digital space are realized.

[0053] Figure 2 A schematic diagram of the construction process of a digital twin model of a vibrating screen according to an embodiment of the present invention is shown.

[0054] like Figure 2 As shown, a static model 201 of a vibrating screen is constructed, and a static model 201 of a vibrating screen including a static model of a support system, a static model of a screening system, and a static model of a conveying system is constructed. Among them, the static model of the support system includes but is not limited to: a static model of a base and a frame. The static model of the screening system includes but is not limited to: a static model of a screen box, a static model of a screen mesh vibration isolation spring, and a static model of an exciter. The static model of the conveying system includes but is not limited to: a static model of an inlet drilling fluid tray.

[0055] Specifically, a three-dimensional geometric model of the system is performed based on the entity of the target system to restore the appearance, shape, proportion and structure of the target system, and a static model 201 of the vibrating screen is obtained. Furthermore, the static model 201 of the vibrating screen is mainly composed of a screen box, a screen vibration isolation spring and an exciter, an inlet drilling fluid tray, a base and a bracket. The vibrating screen is driven by the rotation of the exciter to move the screen box and the screen together, forming a reasonable motion trajectory. The drilling fluid flows to the screen box and the screen through the drilling fluid box, and the solid phase is pushed out from the front of the screen box. The liquid phase containing solid phases smaller than the screen mesh holes passes through the screen and flows into the drilling fluid tank, thereby completing the separation.

[0056] like Figure 2 As shown, a vibrating screen database 202 is constructed, mainly based on the vibrating screen static model 201, which quickly accesses the real-time drilling production data and the real-time vibrating screen operation data during the drilling process. Specifically, the real-time drilling production data includes but is not limited to: daily drilling reports, real-time logging data, and well control intelligent post monitoring data. The real-time vibrating screen operation data includes but is not limited to: screen surface inclination angle, vibration direction angle, screen surface amplitude, vibration times, and material movement speed.

[0057] like Figure 2 As shown, the digital twin model 203 of the vibrating screen is constructed, mainly to realize the data-driven effect of the data-related equipment according to the data category actually connected, and realize the linkage between data and model. Specifically, the real-time data collected from the on-site acquisition equipment is connected to the digital twin system, and the logical association relationship between the real-time data groups is comprehensively analyzed to form a multivariable algorithm model to realize the virtual-real synchronization driven by real-time data. Furthermore, the logical association relationship between the real-time data of drilling production and the real-time data of vibrating screen operation is comprehensively analyzed to form a multivariable algorithm model, decompose the actions of each system under different working conditions, form a correspondence, and realize the triggering of the target system action under the conditions of changes in the real-time data of drilling production and the real-time data of vibrating screen operation.

[0058] The present invention can perform fault diagnosis and prediction of a vibrating screen for drilling, thereby improving the reliability of the vibrating screen.

[0059] The digital twin of the vibrating screen provided by the present invention can help enterprises diagnose and predict equipment failures.
