It should be understood that the following drawings only show certain embodiments of the present application and therefore should not be regarded as limiting the scope.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0024] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] The intelligent modules of coal preparation plants generally adopt the traditional software development process. According to the personalized needs of different sites, different processes, different equipment and users, the process is carried out in sequence according to the steps of demand collection, demand analysis, product design, product development, system testing, delivery and operation. Not only is the overall process long, but each link requires the participation of professionals. In addition to professional knowledge, they also need to have an in-depth understanding of the details of the coal preparation production process. Otherwise, the software system may not meet the production technical requirements of the coal preparation plant.

[0026] Common low-code tools are mostly aimed at software systems with clear business rules, high standardization of logic units, low customization, and shallow business coupling, such as office OA systems. For coal preparation plants, which have a variety of equipment types, software and hardware linkage, and complex equipment executable actions, the same equipment must execute different logics under different process flows and has relationships with other equipment in the entire system, there is currently no low-code tool that can quickly build such business scenarios.

[0027] Based on this, the embodiment of the present application provides a method for dynamically customizing the intelligent software system of a coal preparation plant. The embodiment of the present application is designed and implemented based on the concept of physical models, and the physical objects in the physical world are mapped to the physical models in the software system. The classification of physical models covers all kinds of physical objects used in production management of coal preparation plants in the real world, including but not limited to spatial positions, natural resources, equipment systems, spare parts and consumables, personnel organizations, etc. Each physical model has corresponding attributes, which include the flow chart of the current model and various executable software logics, and realizes linkage with the physical equipment through association with PLC. The software instance created by freely dragging the physical model in the canvas provided by this tool is assembled and combined according to the actual production process. After completing the virtual process flow chart, the mapping with the production process of the physical equipment can be automatically realized. Through the preset attributes and standard logic, the entire process is combined and connected, so as to complete the rapid construction of independent applications.

[0028] Please see Figure 1 , Figure 1 A flow chart of a method for dynamically customizing an intelligent software system of a coal preparation plant provided in an embodiment of the present application. The method for dynamically customizing an intelligent software system of a coal preparation plant includes: 100. Obtain a device flowchart drawing tool, wherein the device flowchart drawing tool includes element types, a canvas, and setting functions.

[0029] Specifically, the element types include: object instances, buttons, and pipeline lines.

[0030] Among them, the position and status of the physical equipment in the entire process flow are obtained through the object instance; the physical equipment is remotely controlled or the real-time status and attribute data of the physical equipment are obtained through the operation interface associated with the object instance; specific operations or logic are triggered in the flow chart through button elements; and object instances of different physical equipment are connected.

[0031] Specifically, an object instance is the representation of the equipment in the flow chart, which directly corresponds to the object model instance. For example, in the equipment flow chart of a coal preparation plant, an object instance representing a specific crusher will be displayed on the canvas. Through the object instance, the operator can intuitively understand the position and status of the equipment in the entire process flow, and can remotely control the equipment or obtain the real-time status and attribute data of the equipment through the operation interface associated with the object instance. The source of these attribute values ​​can be PLC or the result of calculation through other attribute values.

[0032] Specifically, button elements are used to trigger specific operations or logic in the flowchart. For example, there are start buttons, stop buttons, frequency adjustment buttons, emergency brake buttons, etc. These buttons correspond to the executable operations of the equipment. When the operator clicks the corresponding button, a control instruction will be sent to the equipment, thereby realizing manual control of the equipment. The design of buttons enables operators to easily operate the equipment on the flowchart interface without switching to other complex control interfaces.

[0033] Specifically, different equipment instances are connected to represent the relationships between equipment such as material flow, information flow or energy flow. In the process flow of a coal preparation plant, raw coal is transported from the coal feeder to the crusher through a pipeline line, and the crushed product is then transported to subsequent equipment such as screening machines through a pipeline line. The existence of pipeline lines makes the upstream and downstream relationships between equipment clear at a glance, which helps to understand the logical sequence of the entire process flow, and after the data is parsed, it provides a basis and judgment basis for the association analysis and intelligent control between equipment. The pipeline line is a special object instance. It automatically establishes an association relationship based on the connected upstream and downstream and bypass branch object instances, and automatically displays the status, flow rate, flow direction and other information of the pipeline based on the status of the upstream and downstream equipment.

[0034] 200. Obtain the physical model mapped by the physical device in the software system, and link the physical device by associating it with the intelligent control system, wherein each physical model has corresponding attributes, and the attributes include the flow chart of the current model and various executable software logics.

[0035] It can be understood that the physical model is an abstract representation of a class of physical objects in the real world, which maps physical objects in the physical world to the software system. For example, in the coal preparation plant scenario, various types of coal preparation equipment such as crushers, screens, conveyors, etc. have corresponding physical models. Each physical model contains its physical image or dynamic image, which helps to intuitively display the appearance and operating status of the equipment. At the same time, the physical model also covers a variety of attributes, such as the model, power, production capacity, etc. of the equipment, as well as the operations that can be performed, such as starting, stopping, speed regulation, etc. Through this mapping relationship, the system can digitally describe and manage physical equipment, laying the foundation for the subsequent realization of IoT functions.

[0036] The object model can be instantiated into a specific instance. An instance of the object model corresponds to a specific object in the real world. For example, a crusher of a specific model installed in a specific location is an instance of the crusher object model. It inherits the properties and executable operations of the crusher object model and has the unique operating data of the instance, such as the current operating time, cumulative processing volume, etc. Object model instances can freely establish association relationships, including the system they belong to (belonging to other object instances), the components they contain (including other object instances), the upstream and downstream equipment associations (the associations before and after the process flow link), etc. This is one of the important sources of judgment when the object instance executes an operation.

[0037] 300. The software instance created based on the preset canvas is combined with the actual production process and the setting function is applied to assemble and combine to complete the virtual process flow chart and establish a mapping with the production process of the physical equipment.

[0038] In some embodiments, the software instance created based on the preset canvas includes: A software instance is created by freely dragging an object model in the canvas provided by the device flowchart drawing tool; the canvas includes functions of automatic layout, automatic typesetting, and auxiliary alignment.

[0039] Specifically, the automatic layout function automatically adjusts the distribution position of equipment instances on the canvas according to the complexity of the equipment flow chart and the number of equipment; the automatic typesetting function optimizes the arrangement order between equipment and arranges the equipment according to the logical order of the process flow or user-defined rules; the auxiliary alignment function assists in aligning equipment and lines when dragging equipment instances or drawing pipeline lines.

[0040] Therefore, the automatic layout function makes the entire flowchart layout reasonable and beautiful, avoiding the confusion and overlap that may be caused by manual layout; the automatic typesetting function improves the readability of the flowchart; the auxiliary alignment function can accurately align equipment and lines to ensure the standardization and accuracy of the flowchart.

[0041] For example, when a user drags a new equipment instance onto the canvas, the canvas will automatically display auxiliary alignment lines, allowing the user to easily align the instance with other related equipment to ensure smooth and accurate pipeline line connections.

[0042] In addition, when the canvas is saved, the device information on the canvas and its upstream and downstream relationships are stored in a standard format as a complete set of flowchart data. It can be understood that the data is used by the background logic after parsing.

[0043] In some embodiments, the application setting function performs the assembly combination, including: The settings function allows users to adjust the appearance and property display of the flowchart or the currently selected element. For the flowchart as a whole, the user-set appearance is received, where the user-set appearance includes background color, line color and thickness, and font style; for a single element, the user-set appearance attributes are received, where the user-set appearance attributes include: display size, color, transparency, and display or hiding specific property information; for buttons, the user-set button style functions are received, where the user-set button style functions include changing the shape of the button, setting the color of the highlighted operation button, and setting the click feedback effect of the button.

[0044] Thus, users set background color, line color and thickness, font style, etc. to meet different visual needs or meet the company's specific style standards.

[0045] For example, for a single element, in some cases, the user may only be concerned about the operating status of the device. In this case, the detailed technical parameter information of the device can be hidden to make the flowchart interface more concise and clear.

[0046] 400. Through preset attributes and standard logic, the business process of the entire system is combined and connected to complete the construction of independent applications.

[0047] In some embodiments, the combination and connection of the business process of the entire system is established through preset attributes and standard logic to complete the construction of independent applications, including: 410. The location information of the physical equipment and the relationship between the location information of the physical equipment and the pipeline are saved through the equipment flow chart, stored in the database in a standard data format and parsed by the program.

[0048] 420. Through the MQTT message queue telemetry transmission protocol, combined with the front-end polling or button triggering method, the current status and attribute values ​​of each physical device instance are queried in real time; among which, the elements of the query page switch the picture effects according to different states.

[0049] Exemplarily, the running state is a green rotating effect, the shutdown state is a gray static effect, and the high temperature alarm is a red flashing effect.

[0050] 430. After the device flow chart is constructed, the object instances and the association relationship between the object instances are analyzed, and the specified standard logic of the first instance on a task link is triggered through the set interface instructions.

[0051] 440. According to the execution result, the upstream and downstream relationships of the instance are analyzed and found to determine the logic to be executed by the next instance, and complete the combination of the full set of business logic or a set of business instructions.

[0052] It can be understood that after the device flow chart is constructed, the program will parse the object instances and the relationship between the object instances, and trigger the execution of the specified standard logic of the first instance on a task link through scheduled tasks, buttons, interfaces or other program instructions. According to the execution results and parsing the upstream and downstream relationships of the search instances, the logic to be executed by the next instance is determined, thereby completing the combination of a full set of business logic or a set of business instructions.

[0053] 450. Use the device flowchart drawing tool to complete the low-code construction of the system page, where the system page provides dynamic display of status and results.

[0054] In some embodiments, the step of analyzing and searching for the upstream and downstream relationship of the instance according to the execution result to determine the logic to be executed by the next instance includes: In the process flow of a coal preparation plant, different production stages and equipment combinations use different logic controls. The standard logic for execution is determined and the execution parameters are selected based on the current position of the physical equipment in the entire process flow and the operating status of the upstream and downstream physical equipment. The standard logic is the standard logic built into the physical model, and different physical models have different standard logics based on the different executable operations.

[0055] Optionally, the logic combination will decide which standard logic to execute and the selection of execution parameters based on the position of the current equipment in the entire process and the operating status of the upstream and downstream equipment. In the complex process flow of a coal preparation plant, different production stages and equipment combinations require different logic controls. For example, in the raw coal transportation stage, when multiple coal feeders feed a crusher at the same time, the operating logic of the crusher needs to comprehensively consider factors such as the feeding speed of each coal feeder and the particle size of the material, and dynamically adjust the parameters such as the rotation speed of the crusher and the crushing chamber pressure to ensure a balance between the crushing effect and production efficiency. The embodiment of the present application has built-in standard business logic for each type of equipment in the coal preparation plant. These logics are written and optimized based on the professional knowledge of the coal preparation process and actual production experience, and can meet the control requirements of different production links in the coal preparation plant.

[0056] Optionally, the physical model has built-in standard logic, and different physical models have different standard logics according to the different executable operations. For example, a centrifugal pump has built-in startup logic, shutdown operation, and pump frequency adjustment operation. The startup logic includes confirming the power-on status, confirming the valve status, sending a startup command to the PLC, judging whether it is successful, starting to monitor operating parameters such as pressure value, flow, temperature vibration, or returning startup failure information.

[0057] Optionally, the standard logic built into the equipment is judged through the association relationship and production status of upstream and downstream equipment. In the Internet of Things system of the coal preparation plant, there is a close relationship between the material flow and information flow between the devices. For example, when the upstream coal feeder starts feeding, the downstream crusher should start running according to the pre-set standard logic. Information such as the use method, process location, operating status, etc. of the equipment, together with the association relationship between the upstream and downstream equipment, constitute the basis for judging the execution of a certain standard logic. This part of the judgment logic is also one of the main core contents of the embodiments of the present application.

[0058] In some embodiments, the standard logic includes: manual control logic and intelligent automatic logic; specifically, manual control is performed by operating button elements in the device flowchart drawing tool; trigger conditions are configured by timers and timing rules to perform intelligent automation.

[0059] Optionally, the manual control logic is triggered by a page button. The operator operates the button element in the equipment flow chart drawing tool, such as clicking the start button of the crusher. At this time, the manual control logic corresponding to the button will be triggered, and the system will send a start instruction to the crusher and record relevant operation information in the background. The manual control logic is suitable for equipment operation scenarios that require manual intervention, such as equipment commissioning, emergency handling, or manual operation under specific process requirements. It provides operators with direct and flexible means of equipment control.

[0060] Optionally, the intelligent automatic logic is configured with trigger conditions by timers and timing rules. For example, in the screening machine equipment of the coal preparation plant, the intelligent automatic logic of regularly cleaning the screen can be set. The timer is set to check the blockage of the screen every certain period of time (such as 2 hours). When the timing rules are met (such as the blockage rate of the screen exceeds a certain threshold), the logical operation of cleaning the screen is triggered, including starting the cleaning device, adjusting the equipment operating parameters, etc. The application of intelligent automatic logic enables the equipment to automatically perform corresponding operations according to preset rules without human intervention, improves the intelligence level and production efficiency of equipment operation, and reduces the workload and human errors of manual operation.

[0061] As mentioned above, exemplarily, through the equipment flowchart drawing tool, the low-code rapid construction of the system page is completed, and a dynamic display of status and results is provided on the system page. Through the integration with the equipment flowchart drawing tool and the standard logic management function, the application layer can obtain the equipment's operating status information in real time, such as the equipment's current operating speed, temperature, pressure and other parameters, as well as production result information, such as the raw coal processing volume, clean coal output, tailings discharge volume and other data within a certain period of time. This information is displayed on the system page in the form of intuitive charts, data tables or dynamic graphics for management personnel, operators or other relevant personnel to view and analyze. For example, in the monitoring center of a coal preparation plant, the equipment operation status diagram of the entire coal preparation process is displayed on a large screen, and managers can see the operation status of each device at a glance, detect abnormalities in time and make decisions.

[0062] Exemplarily, intelligent control of the equipment can be achieved through an intermediate program or by directly communicating with the PLC. As the core device of industrial control, the PLC is closely connected to the Internet of Things system of the embodiment of the present application. When the button operation or standard logic in the device flowchart drawing tool triggers the control instruction, the system sends the instruction to the PLC, and the PLC controls the sensor, actuator and other perception layer devices of the device according to the instruction. For example, when the start logic of the crusher is triggered, the system will send a start instruction to the PLC, control the motor starter to turn on the power, so that the crusher motor starts to run, and monitor the motor's current, speed and other parameters in real time to ensure the normal start and operation of the equipment. At the same time, the PLC also feeds back the operating status information of the equipment to the Internet of Things system, realizing two-way data interaction and intelligent control between the perception layer and the application layer.

[0063] As described above, the embodiment of the present application obtains a device flow chart drawing tool, wherein the device flow chart drawing tool includes element types, canvases, and setting functions; obtains a physical model of the physical device mapping in the software system, and associates it with the intelligent control system to link the physical device, wherein each physical model has corresponding attributes, and the attributes include the flow chart of the current model and various executable software logics; based on the software instance created by the preset canvas, combined with the actual production process, the setting function is applied to assemble and combine to complete the virtual process flow chart, and then establish a mapping with the production process of the physical equipment; through preset attributes and standard logic, the combination and connection of the business process of the entire system is established to complete the construction of an independent application; thereby, it is possible to quickly build and adjust various intelligent application modules, flexibly adapt to different business processes and scenarios, and at the same time, through a rich standard component library, the basic business logic is encapsulated in the unit component to ensure the correctness of the tool building effect and reduce the customization cycle and cost.

[0064] As mentioned above, the equipment association relationship in the embodiment of the present application: the equipment forms upstream and downstream and association relationships through connecting pipelines in the order of combination, which is convenient for users to intuitively understand the connection and dependency relationship between the equipment, and save it as structured data to provide a clear structural basis for subsequent logical judgment and control. Design based on physical models: Map the physical objects in the physical world to the physical models in the software system, and each model contains physical pictures or dynamic pictures, multiple attributes and executable operations. This is the basis for realizing the drawing of equipment flow charts, and it is also one of the important differences from the prior art. Flexible elements and canvas functions: Elements cover the physical instances, buttons and pipeline lines corresponding to the equipment. The canvas has automatic layout, automatic typesetting, auxiliary alignment and other functions. Users can freely drag the object instance legend to combine equipment according to the process flow, and quickly and easily draw equipment flow charts that accurately reflect the actual situation.

[0065] Built-in standard business logic: Standard business logic is built-in for each type of equipment in the coal preparation plant, which is highly industry-specific and practical, reducing the user's development workload and difficulty. Diversified logic execution methods: The use of standard logic is divided into manual control and intelligent automatic. Manual control is triggered by page buttons, and intelligent automatic is configured with trigger conditions by timers and timing rules, meeting the control requirements in different scenarios. Dynamic logic combination: According to the position of the equipment in the entire system and the operating status of upstream and downstream equipment, it determines which standard logic to execute and the selection of execution parameters, realizing dynamic adjustment and optimization of logic and improving the intelligence and automation level of the system.

[0066] Interactive display between the system and the application layer: It can provide the application layer with a dynamic display of status and results on the system page, which is convenient for users to understand the operation of the equipment and the progress of the business process in real time, and enhances the visualization and interactivity of the system. Collaborative control with the perception layer: Through collaboration with the PLC, intelligent control of the equipment is realized, and the instructions of the application layer are accurately transmitted to the perception layer to complete the actual operation of the equipment, forming a complete IoT control closed loop. The low-code development feature is reflected: As a low-code development tool, it lowers the development threshold, reduces the development workload, and improves the development efficiency through visual operation methods and preset module functions, so that non-professional technicians can also quickly build IoT applications that meet specific needs.

[0067] The above steps are not to be performed in a strict order as described in the numbers, but should be understood as an overall solution.
