[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0053] To facilitate understanding of the technical solutions in the various embodiments of this application, a brief explanation of the technical terms that may appear in the various embodiments of this application is provided first:

[0054] 1) Operation Management & Control System (OMC), also known as the next-generation full-process intelligent operation management and control system, integrates core technologies such as factory operating system, industrial AIoT (artificial intelligence + Internet of Things), advanced industrial network, intelligent optimization, and model prediction on the basis of traditional distributed control system functions.

[0055] 2) Materials refer to all materials, raw materials or items related to product production, such as raw materials, auxiliary supplies, semi-finished products, finished products, etc.

[0056] 3) Free proportioning: In process industries (such as chemical, pharmaceutical, metallurgical, food and other continuous production fields), free proportioning of materials refers to the ability and mode to flexibly and dynamically adjust the proportion of various materials (such as raw materials, additives, catalysts, etc.) involved in production according to factors such as process requirements, raw material characteristics, product specifications or market changes.

[0057] 4) Function blocks refer to a type of function block that can be created, edited, and deleted by the user. Global function blocks can be used by any control station and operator station within this project, thereby reducing on-site configuration workload and improving project efficiency and reusability. For example, frequently used configurations can be extracted as global function block common templates.

[0058] 5) Structured text (ST) is one of the five languages ​​supported by the IEC 61131-3 standard. It is a block-structured high-level language, and all languages ​​share common elements of the IEC 61131 standard. Variables and function calls are defined by common elements, so different languages ​​from the IEC 61131-3 standard can be used in the same program.

[0059] For example, this application provides a control system for freely proportioning materials. The system includes: a control panel, and on / off valves, regulating valves, and flow transmitters located on each independent conveying pipeline; wherein, the control panel displays a control interface, which displays at least one of the following information: process steps, feed rates of various materials, temperature setpoints, and reaction times; the on / off valves control the opening and closing of the conveying pipeline channels according to the on / off signals sent by the control panel; the regulating valves automatically adjust their opening degree according to the material flow data fed back in real time by the flow transmitters through a proportional-integral-derivative control algorithm.

[0060] For example, Figure 1 This is a schematic diagram illustrating an application scenario of a control system for freely proportioning materials in one embodiment, such as... Figure 1The diagram illustrates various feeding controls for a bisphenol A carbon-based resin reactor. In this embodiment, the core objective is to achieve high-precision quantitative delivery of multiple fluid materials. A control system with freely proportioned materials is constructed to precisely deliver various fluid materials to the reactor according to preset mass parameters. Optionally, the system is configured with independent delivery pipelines for each fluid material. Each pipeline is sequentially equipped with an on / off valve, a regulating valve, and a flow transmitter, which work together to form a closed-loop control system. The on / off valve is responsible for opening and closing the material delivery channel; the regulating valve automatically adjusts its opening based on real-time material flow data from the flow transmitter using a PID control algorithm, ensuring that the material flows into the reactor at a constant and precise mass flow rate. This effectively avoids proportioning errors caused by flow fluctuations, laying a stable foundation for subsequent chemical reactions.

[0061] For example, in combination Figure 1 As shown, the control panel is also used to: determine the feeding sequence of each material in response to the setting operation of the process steps; determine the feeding amount of each material in response to the setting operation of the feeding amount of various materials; and determine the corresponding temperature set value in response to the temperature setting operation of various materials and / or the reaction process.

[0062] In this embodiment, by equipping an intuitive control panel, operators can set parameters such as material feed rate and feed sequence according to production process requirements.

[0063] For example, the control panel also displays an execution mode setting control, which is used to switch between different execution modes; wherein, the execution modes include: sequential execution mode and step-by-step execution mode; in sequential execution mode, various materials are added in sequence according to the preset process steps; in step-by-step execution mode, a step sequence dialog box is displayed on the control interface, and in response to the setting operation of the step sequence dialog box, the steps to be executed first or the steps to be skipped are specified.

[0064] In this embodiment, the system is equipped with an intuitive and convenient control panel, allowing operators to flexibly set key parameters such as the feed rate and feed sequence for each material according to production process requirements. Optionally, the system supports two execution modes: in sequential execution mode, each material will be added in strict accordance with preset steps; while in step-by-step execution mode, operators can freely specify steps to be executed first or skipped through the step sequence dialog box, which is particularly suitable for complex and ever-changing production needs, thereby significantly improving the customizability and execution efficiency of the feeding process.

[0065] For example, the control panel also displays a switching control for selecting manual mode or automatic mode; in automatic mode, various materials are added sequentially according to the preset feeding sequence, feeding amount, and temperature setting; in manual mode, the corresponding parameter is adjusted in response to the adjustment operation of at least one of the parameters displayed on the control panel, such as process steps, feeding amount, temperature setting, and reaction time.

[0066] In this embodiment, to address unexpected situations and special needs during the production process, the system also features a flexible manual / automatic switching function. Operators can easily switch between automatic and manual operation modes at any time using the prominent switching controls on the panel.

[0067] Optionally, taking defoamer addition as an example, if it is observed that the defoaming effect is not completely achieved due to improper initial parameter settings after the automatic addition of defoamer in the fourth step, the operator does not need to interrupt the entire production process. They can immediately switch to manual mode and manually adjust the amount and speed of defoamer addition according to the actual foam situation until the foam is completely eliminated. This demonstrates the system's dynamic adaptability to the production process and the convenience of human intervention.

[0068] For example, the control panel also displays a prompt function interface, which displays at least one of the following information: the name of the material currently being added, the completed steps, and the remaining steps; wherein, a preset prompt signal is issued at the beginning and end of each process step; the prompt signal includes: an audible and visual signal.

[0069] In this embodiment, to ensure that operators can monitor the feeding process in real time and avoid operational oversights, the system has specially developed an execution step prompt function. This function displays key information such as the name of the material being added, completed steps, and remaining steps in a graphic and textual format on the panel display screen in real time; at the same time, in conjunction with the audio-visual prompt device, clear prompt signals are issued at the beginning and end of each step, comprehensively improving the visualization and continuity of the operation process.

[0070] For example, the above system also includes: a temperature sensor located in the reactor and a timer; the temperature sensor is used to collect temperature data in the reactor in real time and transmit the temperature data to the control panel through a feedback adjustment loop; the control panel is also used to: receive the temperature data transmitted by the feedback adjustment loop, and automatically turn on the heating device or cooling device to adjust the temperature in the reactor when the temperature data deviates from the temperature set value; the control panel is also used to: determine the reaction time according to the timer, and trigger the execution of the next process step when the reaction time reaches a preset threshold; thereby achieving precise process control and reducing manual intervention.

[0071] In this embodiment, the temperature setpoint is one of the core parameters and forms a feedback regulation loop with the temperature sensor inside the reactor. When the actual temperature deviates from the preset value, the system will automatically start the heating or cooling device to adjust it, ensuring that the chemical reaction is always in the optimal temperature range.

[0072] In this embodiment, the reaction time is precisely controlled by a built-in timer. Once the reaction time reaches a preset threshold, the system automatically triggers subsequent operation procedures. The introduction of these constraints not only meets the stringent requirements of the process industry for chemical reaction conditions but also effectively reduces the risk of process deviations caused by human factors through automated control.

[0073] For example, the control panel also displays a reset control, which is also used to: execute a reset procedure in response to a touch operation on the reset control; the reset procedure includes: controlling the switch valves and regulating valves on each delivery pipeline to return to the initial closed state, controlling the flow transmitter to zero and reset, and restoring the parameters on the control panel to their default settings.

[0074] In this embodiment, once the entire feeding and reaction process is successfully completed, the operator only needs to tap the reset control, and the system will automatically perform a series of reset operations: all conveying pipeline valves return to their initial closed state, the flow transmitter is zeroed and reset, the control panel parameters are restored to their default settings, and all executing equipment quickly and accurately returns to its initial standby position, making full preparations for the next feeding operation.

[0075] For example, such as Figure 2 As shown, Figure 2 The document displays the names, tag numbers, and initialization status of each valve on the delivery pipeline. This is achieved by compiling a list of the initialization statuses of the execution equipment (such as...). Figure 2 As shown, upon receiving a touch operation on the reset control, a reset action is performed according to the list of initialization states. Optionally, in the OMC system, the reset action can be implemented using ST language via user function blocks.

[0076] For example, an IF statement can be used to determine whether to reset the valve. If the variable is true, a reset operation is performed on the valve. The reset variable REST can be configured through the OMC system's monitoring system to provide a 3-second pulse signal when the corresponding command is pressed, thereby preventing continuous assignment of values ​​by the program and ensuring that the actuator can operate normally.

[0077] In summary, with such a highly integrated and intelligent control scheme, the system provided in this embodiment can be widely used in multiple industries such as chemical, pharmaceutical, and food industries, providing a reliable and efficient solution for various production scenarios that require precise proportioning of multiple materials.

[0078] For example, Figure 3 A flowchart of a method for controlling the free proportioning of materials provided in an embodiment of this application is shown below. Figure 3 As shown, this method can be applied to the above-mentioned control system for free material proportioning, and the method may include the following steps:

[0079] Step S301: The flow rate of the flow transmitter on each delivery pipeline is statistically analyzed by the integral function block encapsulated in the intelligent operation management and control system.

[0080] Specifically, flow accumulation begins when the value of the flow transmitter is greater than 0; accumulation stops when the value of the flow transmitter is not greater than 0, or when the switch valve on the delivery pipeline is closed.

[0081] Step S302: Set the cumulative completion value of the integral function block according to the feed rate set on the control panel of the material free proportioning control system.

[0082] Step S303: When the cumulative completion value reaches the preset condition, the integration function block outputs a command signal, which is used to instruct the opening and closing of the corresponding conveying pipeline valve.

[0083] Step S304: After the switch valve of the corresponding delivery pipeline is closed, the completion mark is displayed in the integration function block, and the accumulated amount is reset.

[0084] For example, Figure 4 This is a schematic diagram of the traffic statistics interface of the integration function block in one embodiment of this application, as shown below. Figure 4 As shown in the figure, the flow accumulation configuration for each pipeline's flow transmitter is first completed using the encapsulated integral function block (INTERGRALX) in the OMC system. The configuration principle is as follows: flow accumulation begins when the flow transmitter value is greater than 0; accumulation stops when the flow rate is less than zero or when the valve on the pipeline is closed.

[0085] In this embodiment, by associating the cumulative completion value of the integral function block with the feed rate on the proportioning system's operation panel, the integral function block outputs a command signal when the cumulative completion value reaches a preset condition. Upon receiving this command signal, the corresponding action can be executed, closing the corresponding valve. This achieves the function of feeding a single material according to preset parameters. Following this logic, multiple control units for material feed rates can be added until the actual needs are met.

[0086] Optionally, multiple control units can be listed using the CASE statement. For example, if two materials need to be fed into the reactor sequentially according to a preset feed rate, the first step of the CASE statement is executed to determine whether the program is in automatic mode (AUTO1) and whether the AUTO variable is true. If true, the feed rate parameter on the material proportioning control panel is assigned to the cumulative completion value 104FIQ31002.FOUT of the integral function block, and then the shut-off valve XV5 of the pipeline is opened. At this time, the valve is open, and the flow rate will increase. When the cumulative completion value meets the condition, the valve is closed, the completion flag WC1 is output, the cumulative amount is reset, and then the process jumps to the second step to execute the second control unit. By adding multiple control units, multi-material proportioning control can be achieved.

[0087] In this embodiment, multiple control units can be added as needed to achieve free proportion control of various materials. The reaction time and reaction temperature can be adjusted through the operation panel. Manual feeding can be switched at any time through human intervention, and the type of feed can be switched at will by changing the step sequence.
