Description

Technical Field

[0001] The present invention relates to the technical field of automated logistics, and more particularly to a SCADA system construction method based on a BIM model and a SCADA system. Background Art

[0002] The development cycle of large-scale SCADA systems developed in the traditional automation field is relatively long, and project production cannot be completed quickly and flexibly. It is difficult to increase or decrease model equipment and optimize operations in the later SCADA projects. Large-scale SCADA systems have problems such as operation jams and long loading time for switching monitoring interfaces. Usually, the monitoring interface in the SCADA system is mainly displayed in two-dimensional images, and the client uses a single screen for display. The number of displayed devices is very limited. The system uses two-dimensional graphics or pictures as the background image of single-machine equipment, and the display is not intuitive.

[0003] At present, there are many patents on digital modeling, among which patent CN101853521B discloses a method for three-dimensional digital modeling of rotating structured light of cultural relics, which uses a line laser scanner with a laser beam energy not exceeding 2 watts to generate stable line structured light on the surface of the cultural relic, and calculates the three-dimensional coordinates of the scanned line structured light section; uses a binocular CCD stereo vision system to synchronously shoot the cultural relic image, obtains a rotation matrix consisting of a stereo image pair of the cultural relic and external orientation posture elements, and then calculates the line characteristic equation to generate a line feature point set, and establishes a corresponding relationship between the two line feature point sets of the stereo image pair and calculates the three-dimensional coordinates of the cultural relic line section, calculates the three-dimensional coordinates of the scanned line structured light section at each rotation angle and the three-dimensional coordinates of the cultural relic line structured light section, and establishes a three-dimensional digital model of the cultural relic; however, this method mainly performs three-dimensional digital modeling of rotating structured light of cultural relics, and does not provide a description of parameter setting and transmission methods, nor does it explain the project development efficiency, especially the development of digital modeling methods for SCADA systems.

[0004] There are many patents on BIM lightweighting. Among them, patent CN109165394B discloses a method for realizing lightweight standardized BIM models, including standardized establishment of BIM models, standardized processing of model data, standardized conversion of model formats, and association between models and data. Ultimately, the BIM model carrying comprehensive and complex information can be smoothly displayed and operated on PCs and mobile terminals, providing a basis for subsequent developers to expand the application of BIM technology on mobile handhelds. However, this method mainly performs lightweight processing and optimization on static building models. Static building models are not the main monitoring objects of the SCADA system, and the equipment models in BIM cannot be applied to the three-dimensional SCADA monitoring system, and the digital twin information of the equipment cannot be viewed.

[0005] There are relatively few patents on displaying multiple partitions. Among them, patent CN102662621B discloses a multi-terminal multi-partition display interactive interface control method based on configuration drive, which is composed of a display configuration control module and a display processing module to form a display control configuration based on configuration drive, which is isolated from the display process control through display configuration control to perform independent display configuration management, thereby realizing a display control configuration based on configuration drive. By establishing this display control configuration to design and develop a multi-terminal or multi-partition display control interface, it can effectively adapt to a large number of display configuration demand changes in the display interface design process, and these changes are defined and maintained using unified display configuration data, thereby improving the application scalability and maintainability of the display control system. However, this method is based on driving for multi-partition display, and requires configuration and analysis of multiple components such as a driving server, a driving module, and a display module. The hardware cost is high, the component configuration is complex, and the usage scenarios are limited.

[0006] Therefore, how to solve the efficiency problems of establishing two-dimensional and three-dimensional SCADA system projects, the problem of system operation jams, and the problem of non-intuitive observation equipment and cumbersome operation of SCADA system, so as to achieve the purpose of improving the efficiency of SCADA system project development, system operation smoothness and user convenience, is a problem that technical personnel in this field urgently need to solve.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] Embodiment 1

[0063] The embodiment of the present invention discloses a SCADA system construction method based on a BIM model, such as Figure 1As shown, the following steps are included:

[0064] A method for constructing a SCADA system based on a BIM model comprises the following steps:

[0065] S1. Establish a digital BIM model based on equipment type and equipment parameters, and perform hierarchical processing and digital-analog separation on the BIM model according to different hierarchical requirements to obtain a BIM equipment model and a BIM information model, which are stored in the database;

[0066] S2. Perform lightweight processing on the geometric model of the BIM equipment model after hierarchical processing according to the display accuracy of the 3D mode and 2D mode of the SCADA system at different levels;

[0067] S3. Apply BIM equipment model to 2D SCADA system and 3D SCADA system;

[0068] S4. Design the SCADA system in layers, plan the level of detail of device display in each layer, load model devices of different layers according to the requirements of different layers, and use a multi-layer interface to display device status information;

[0069] S5. Perform dynamic data lightweight processing on the SCADA system background data according to the display interface level to reduce the data processing load;

[0070] S6. Read the equipment-related information from the database of the BIM information model to complete the information loading of the current equipment model;

[0071] S7. Collect the operating status and alarm status of all equipment on site, display them in real time in the SCADA system, record the alarms in the alarm database in a list format, and promptly feedback the alarm status of system equipment in the alarm display area;

[0072] S8. Create an overview page of the system control and parameter configuration page, which integrates the control buttons and parameter configurations of all subsystems of the system into one page, which is used to issue overall control instructions for the system and set system parameters;

[0073] S9. Multi-partition centralized display function production, set partition display mode parameters, and each partition can freely switch the display content in the partition through parameter adjustment.

[0074] In order to further implement the above technical solution, the specific contents of step S1 include:

[0075] S11. Classify according to different equipment types;

[0076] S12. Establish equipment templates and information templates according to different types of equipment, and produce equipment templates and information templates of different precisions according to the production accuracy of the monitoring interface level;

[0077] S13. Establish different equipment parameters according to the equipment type, including basic parameters of equipment geometry, attribute color parameters of components, angle parameters of turning equipment, slope parameters of climbing equipment, etc.;

[0078] S14. Establish a device list to count all detailed information of device templates and information templates;

[0079] S15. Apply the equipment template to the project, adjust the equipment parameters according to different sizes and positions, and quickly arrange the project equipment.

[0080] In actual applications, BIM model development and processing can be processed in independent model production platforms, such as 3Dmax, Maya, Solidworks, Revit, Rhino and other software platforms, or it can be developed based on SCADA three-dimensional software platforms, such as Sym 3, King SCADA, Iconics and other software platforms.

[0081] In order to further implement the above technical solution, the device template has the functions of parameter transmission and parameter modification, so that a small number of device object templates can be used to flexibly and quickly build complex project projects. This method greatly shortens the project development cycle and solves the problem of low project development efficiency.

[0082] In order to further implement the above technical solution, the different levels in step S1 are required as follows: the first level is the system overview diagram, which displays the overall status of all conveyor lines in the system; the second level is the subsystem overview diagram, which displays the overall status of the subsystem; the third level is the equipment stand-alone display diagram, which displays the main status information of the stand-alone machine; the fourth level is the equipment component display diagram, which displays the main status information of each component.

[0083] In order to further implement the above technical solution, in step S2, the lightweight processing of the geometric model is mainly concentrated on the first and second levels, and the lightweight processing of the geometric model is performed on the first and second level display contents according to the three-dimensional mode and two-dimensional mode of the SCADA system.

[0084] In order to further implement the above technical solutions, the specific contents of BIM model lightweight processing include:

[0085] BIM model template: Use similarity algorithms to match and classify elements in the model, identify duplicate or similar components, and merge them to reduce the amount of data; use clustering algorithms (such as K-means, DBSCAN, etc.) to aggregate similar components to reduce the complexity of the model;

[0086] For example, for conveyors of the same type, a shared geometry is created, and only the data of one component is retained. Other similar components are recorded through "reference + spatial coordinates", which effectively reduces the storage volume of components.

[0087] In this embodiment, in order to solve the problem that the storage capacity of the BIM model is greatly increased due to the large number of equipment types, a templated approach is used to construct the project, which greatly reduces the number of equipment types. At the same time, the system layout of a complex project can be completed using fewer BIM template library files, thereby reducing the storage capacity of the BIM model.

[0088] BIM model parameter data cleaning: For BIM model parameters describing different objects, through parameter data cleaning, one or more necessary variable parameters are retained for flexible adjustment of equipment shapes in the project;

[0089] In this embodiment, when designing the parameters of the horizontal conveyor model, the width of the conveyor belt and the height of the conveyor are generally relatively fixed. In the BIM template file, only one transferable variable parameter, "length", needs to be set. When the BIM template is used in the project, the length parameter can be adjusted to obtain equipment of different lengths; in the curved conveying equipment model, the curve radius and the width of the conveying equipment are relatively fixed, and only one variable parameter, the curve angle, needs to be retained; in the elevator equipment model, the length and height are relatively fixed. In the project model layout, elevator models of different heights can be quickly obtained by adjusting the elevator height parameter; parametric design provides flexibility and scalability for project layout, and the necessary parameters are retained through parameter cleaning technology, thereby reducing the data volume of model parameters;

[0090] Model body replacement or simplification: Use a simple device description model to replace a complex device model body. For example, in a model system, a rectangular body can be used to replace a cylinder, and a rectangle can be used to replace a polygon in a two-dimensional model system. Reduce the model details and data volume by reducing the number of model vertices. The number of vertices can be reduced as much as possible while maintaining the model accuracy. Reduce the number of polygons and maintain the overall shape recognizability by using edge folding and vertex merging.

[0091] System segmentation: In the SCADA system platform, a large model is divided into multiple smaller subsystem models, and an independent display parameter switch is set for each subsystem to enable users to load and render on demand, avoid loading too many models at one time, and effectively improve the transmission and processing speed; an independent display parameter switch is set for the system change part to independently operate the BIM model of the changed part;

[0092] Data model separation: Split the geometric data and non-geometric data of the BIM model, separate the geometric information of the BIM model from its attribute data, and only retain the main structure and shape of the model body. The remaining detailed attribute data information is stored in the database and loaded according to the needs of different levels of SCADA.

[0093] In order to further implement the above technical solution, in step S4, the SCADA system is designed in four layers, specifically:

[0094] In the first level, the SCADA system's two-dimensional overview displays mainly lines to indicate the overview of all the system's equipment, and the SCADA system's three-dimensional overview displays mainly three-dimensional lines to indicate the overview of all the system's equipment; in the second level, the system's two-dimensional overview displays all the subsystem's conveyors in the form of a block diagram by default, and the system's three-dimensional overview displays all the subsystem's conveyors in a three-dimensional stereogram by default; in the third level, the two-dimensional system displays the equipment's operating status indicated by a frame, and the three-dimensional system displays the equipment's operating status indicated by a three-dimensional model; in the fourth level, the equipment component status displayed in two-dimensional and three-dimensional modes is displayed.

[0095] In order to further implement the above technical solution, in step S5, dynamic data lightweight processing of the SCADA system background data is mainly concentrated on the first and second levels. The first level only edits the data of the comprehensive status of all subsystems, and the second level edits the data of the comprehensive status of all conveyors of the subsystem. At the third level, only the data of the current single-machine device is read and refreshed, and the fourth level only reads and refreshes the data of the current component.

[0096] In order to further implement the above technical solution, the method of dynamic data lightweighting of the SCADA system background data specifically includes:

[0097] Data structure template: According to the type of equipment template, the data structure is designed as a template, and a large number of complex data processing methods are grouped into data structures, thereby greatly improving data processing efficiency;

[0098] In this embodiment, a small number of unified data structure templates are used in the SCADA system for processing. For devices with similar data structures, device data processing is completed by adding 1-2 parameters in the templated program block in the SCADA system program background;

[0099] Hierarchical data optimization processing: According to the display requirements of different levels for monitored objects, the status data displayed on the device is different, and only the data of the corresponding level is processed in each level;

[0100] In this embodiment, in the first-level interface, the equipment operation and fault of the conveying equipment are displayed; in the second-level interface, the operation, fault, emergency stop, energy saving, cascade status of the conveying equipment and the action status of important parts of the equipment are displayed; in the third-level interface, all states of the conveying equipment such as operation, fault, emergency stop, energy saving, cascade, forward conveying, reverse conveying, isolating switch, photoelectric tube blockage, air switch fault, driver fault, inverter fault, etc. are displayed; in the fourth-level interface, detailed data of each component is displayed, such as parameter information such as voltage, current, frequency, etc. of the drive motor; the use of hierarchical processing method greatly reduces the concurrent processing volume of background data, and effectively divides the data processing according to different levels, thereby achieving the purpose of data lightweighting;

[0101] Scene depth optimization: for different display levels, the model display can be made lightweight by changing the depth of field parameters of the SCADA system;

[0102] In this embodiment, the depth of field parameter is set in the SCADA system to adjust the detail level of viewing the conveying equipment. Different display components and precisions can be defined in each level according to the level display requirements. When the user operates the system to zoom, the system models of different precisions in the same level can be viewed. For example, in the first level interface, under the depth of field parameter of 100-400, each sub-equipment can be seen to be composed of a line; under the depth of field parameter of 400-800, the system can be seen to be composed of a rectangular body; under the depth of field parameter of 800-1500, each system can be seen to be composed of important components such as the side panels of the conveying equipment and the conveying belt;

[0103] Data and model preloading and caching: Use preloading and caching technology to preload or cache system model files that users frequently view based on their browsing habits to increase display speed;

[0104] In this embodiment, the SCADA system captures user usage habits through deep learning, and the system interfaces and data frequently used by users are preloaded or cached. When the user accesses the SCADA system model, the required model and information can be quickly read from the cache.

[0105] In order to further implement the above technical solution, in step S6, the SCADA system completes the loading of the information model in the third level. When a single-machine device display diagram is clicked in the two-dimensional system or the three-dimensional system, the SCADA system background reads the device-related information from the information model database according to the device number to complete the information loading of the current device model.

The basic equipment model can be processed in a lightweight way. The geometric accuracy and information accuracy of the two-dimensional system equipment reach the G1 and N1 levels respectively, and the geometric accuracy and information accuracy of the three-dimensional system equipment reach the G2 and N1 levels respectively; at the subsystem overview interface level, the overall situation of a single or multiple subsystems is displayed according to the system category, and the necessary detection devices and the operating status of important devices are displayed, such as: RFID The operation / fault of the equipment, the activation status of the emergency stop button station, etc., the geometric accuracy and information accuracy of the monitoring system equipment reach G2 and N2 levels respectively; at the single-machine equipment display level, it mainly displays the operating status information of the single-machine equipment and the static information of the current equipment. The operating status information can be obtained through the on-site Internet of Things, and static information such as motor model, power, geometric dimensions, etc. can be obtained through the database. At the same time, the position and connection relationship of all parts of the equipment can be clearly observed through the exploded view of the equipment. The geometric accuracy and information accuracy of the equipment reach G3 and N3 levels respectively; at the equipment component level, detailed information of each component is displayed, such as the operating status of components such as motors, drivers, sensors, and component models, etc. The geometric accuracy and information accuracy of the equipment reach G4 and N4 levels respectively.

At this level, the system model is optimized in a lightweight way, which can greatly reduce the system operation load and solve the problem of monitoring system operation jams.

[0122] In this embodiment, the partition display module is described by taking 4 partitions as an example. Figure 4As shown in the figure, after the SCADA system is started, by default, the first partition is a two-dimensional system overview, the second partition is a three-dimensional system overview, the third partition is a system alarm list, and the fourth partition is a system control command interface. All partitions can be freely switched to the required interface through the navigation button according to user needs. The two-dimensional interface and the three-dimensional interface in the system are used together to meet the usage habits of different users. At the same time, the equipment failure status in the system can be quickly viewed through the alarm list, and quickly handled through the system control command interface. The design of this solution can solve the problem that the number of monitoring devices that users can view is limited and the system equipment status display is not intuitive.
