[0022] It should be understood that the description in this section is not intended to identify key or essential features of the embodiments of this application, nor is it intended to limit the scope of this application. Other features of this application will become readily apparent from the following description. Attached Figure Description

Wherein: Figure 1 This is a flowchart illustrating an automatic working fluid switching control method provided in an embodiment of this disclosure.

Detailed Implementation

[0024] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0025] The following description, with reference to the accompanying drawings, outlines an automatic working fluid switching control method, apparatus, electronic device, and storage medium according to embodiments of the present disclosure.

[0026] Figure 1 This is a flowchart illustrating an automatic working fluid switching control method provided in an embodiment of this disclosure.

[0027] like Figure 1 As shown, the method includes the following steps: Step 101: Acquire the status data of the working fluid to be processed in real time; Status data should be interpreted broadly, referring to any measurable parameter that can directly or indirectly characterize the current quality, composition, or physicochemical properties of the working fluid. This parameter is the sole direct basis for subsequent quality assessment and flow control. The purpose of acquiring this status data is to provide the control system with continuous, immediate, real-time information from the field, completely replacing manual sampling and analysis, and eliminating judgment delays and human errors.

[0028] The term "real-time acquisition" refers to the online and continuous monitoring of the working fluid through a measuring device directly or indirectly coupled to the working fluid flow path, and the instantaneous conversion of the monitoring results into a signal form recognizable by the system. The acquisition frequency and response speed are sufficient to ensure dynamic capture of changes in the working fluid's state. The measuring device here is not limited to any specific sensor in terms of physical configuration, as long as it can sense and output quantitative information related to the working fluid's qualified / unqualified state.

[0029] As a specific implementation method, taking the regeneration wastewater treatment process in a thermal power generating unit as an example, the working fluid to be treated is the wastewater generated after rinsing the resin, and the real-time acquired state data can be the conductivity value of the wastewater. In this scenario, a conductivity measuring instrument (such as the conductivity meter in a specific embodiment of the present invention) can be installed in the bypass of the wastewater conveying pipeline, allowing the wastewater to continuously flow through the measuring probe, thereby converting the ion concentration information of the wastewater into a standard electrical signal in real time and continuously, thus completing the acquisition of state data.

[0030] Step 102: Determine whether the working fluid to be processed meets the recycling conditions based on the status data; The so-called recycling conditions refer to the pre-set quantitative quality thresholds used to determine whether the working fluid is suitable for recycling and reuse. Their specific meaning is not limited to a single physicochemical index threshold, but also includes composite criteria resulting from the logical combination of multiple parameters. This judgment is automatically completed by the control system, essentially comparing and analyzing the acquired real-time status data with the pre-stored benchmark conditions in the system to generate a deterministic "qualified / unqualified" or "satisfied / unsatisfied" logical conclusion.

[0031] This process completely replaces manual judgment based on experience, ensuring the consistency and objectivity of the evaluation criteria. As a specific implementation method, in the application of wastewater recycling in thermal power plants, this step involves the distributed control system (DCS) comparing the real-time collected wastewater conductivity values ​​with the set water quality compliance threshold. When the conductivity is lower than a certain limit, it is determined that the recycling conditions are met.

[0032] Step 103: When it is determined that the recycling conditions are met, a switching command is generated to drive the switching valve to actuate so as to introduce the working medium to be processed into the recycling pipeline. The switching command is an electrical or pneumatic control signal automatically triggered by the control unit after receiving the logical conclusion that "recovery conditions are met". Its signal form and physical carrier are not limited to a specific type, as long as they can drive the downstream execution terminal. The term "switching valve" should be interpreted broadly, referring to any flow path control device controlled by this command that can switch the direction of the working fluid flow by changing its own opening / closing state or flow channel connectivity. Its driving method can be electric, pneumatic, hydraulic, or electromagnetic, etc.

[0033] A recycling pipeline is a separate fluid channel, distinct from the waste discharge path, specifically designed to transport qualified working fluids to reuse processes or storage containers. Logically, this switching process is mutually exclusive with the discharge control of unqualified working fluids, ensuring a strict correspondence between working fluid quality and flow direction. As a specific implementation, in the application scenario of wastewater recycling in thermal power plants, this step involves the distributed control system (DCS) controller sending a digital output signal, transmitted via cable to a pneumatic actuator on-site. This actuator drives the pipeline valve to switch the wastewater meeting conductivity requirements from its original direct discharge to the waste liquid pool to the newly added recycling pipeline, thereby achieving immediate recycling of qualified wastewater.

[0034] Automated mechanical execution replaces the physical act of manually operating valves. This step achieves seamless automation from sensing and judgment to execution, ensuring the immediacy and reliability of working fluid recovery and eliminating the delays and risks of manual switching.

[0035] Step 104: Obtain the position status information of the switching valve and feed it back to the control unit to confirm the execution result of the switching command.

[0036] The closed-loop verification stage, built upon the aforementioned automatic execution, functions to establish a real-time monitoring and feedback mechanism for the actual effect of the switching action, ensuring that the control command has been executed correctly and completely. The "position status information" refers to any physical quantity signal that can truly reflect the current working state of the switching valve (e.g., fully open, fully closed, or an intermediate position). Its acquisition method is not limited to contact or non-contact sensing, as long as the actual mechanical position of the valve can be converted into a feedback signal recognizable by the control system. "Feedback to the control unit" means transmitting this position status information back to the same control unit that issued the command or other cooperating control units via a signal transmission link to form an information closed loop.

[0037] The "confirmation" behavior, functionally speaking, involves the control unit logically comparing the received actual position status information with the expected valve position status corresponding to the issued switching command. When the two match, the switching action is deemed successfully completed; when an inconsistency is detected, the system can identify an execution fault, providing a basis for subsequent alarm or protection logic. As a specific implementation method, in the application of wastewater recycling in thermal power plants, this step can be achieved through a feedback switch installed on the pneumatic actuator: when the valve is in position, the feedback switch contact state changes, and this open / closed state signal is sent via cable to the digital input channel of the distributed control system (DCS). The DCS controller logically verifies this signal against the output valve control command and simultaneously displays the valve position status in real time on the operator's monitoring screen, thus automatically confirming the execution result of the switching command.

[0038] Through this step, the control system not only has the open-loop capability of "command-execution", but also realizes the closed-loop verification of "execution-feedback", which significantly improves the reliability, controllability and diagnosability of the working fluid automatic switching system.

[0039] In some embodiments, the real-time acquisition of the status data of the working fluid to be processed includes: A sample stream is extracted from the pipeline transporting the working fluid to be treated, the conductivity of the working fluid is detected, and the conductivity data is converted into a standard electrical signal output.

[0040] A sampling port is opened along the flow direction on the main process pipeline transporting the working fluid to be processed. Through an instrument sampling pipeline sealed to it, a small portion of the bypass sample flow, representing the current overall quality of the working fluid, is continuously extracted from the pipeline, realizing the "sample flow extraction" function that is dynamically synchronized with the working fluid in the main pipeline. The instrument pipeline continuously guides the sample flow to a conductivity measuring device, which includes a measuring probe that is in direct contact with the sample flow. This measuring probe is the conductivity meter measuring probe described in the disclosure document.

[0041] The probe internally encapsulates one or more pairs of electrodes to which a constant alternating voltage is applied. When the sample current flows through the measurement chamber between the electrodes, its conductivity directly affects the magnitude of the current in the circuit. The built-in transmitter circuit of the measuring device (i.e., the core functional part of the conductivity meter in the manual) detects this current change in real time and, based on a preset electrode constant and temperature compensation algorithm, accurately converts it into a standard analog electrical signal that is linearly related to the conductivity of the working fluid, such as a 4-20mA DC current signal or a 0-10V DC voltage signal. This signal is then transmitted to the control system via a signal cable, thus fully realizing the technical process of "detecting conductivity and converting it into a standard electrical signal output". Therefore, this conductivity signal becomes a direct quantitative indicator characterizing the total amount of soluble ionic impurities in the working fluid.

[0042] In some embodiments, determining whether the working fluid to be processed meets the recycling conditions based on the status data includes: The conductivity value represented by the standard electrical signal is compared with a preset recycling standard threshold. When the conductivity value is less than or equal to the recycling standard threshold, the working fluid to be processed is determined to meet the recycling conditions.

[0043] A set of explicit numerical comparison logic is executed within the control unit. The preset recycling standard threshold is an upper limit value of conductivity determined in advance through experiments or process requirements. This threshold is tuned and stored in the control system's storage unit, serving as the sole quantitative benchmark for determining whether the working fluid can be recycled. In actual operation, the control unit receives a standard electrical signal (e.g., a 4-20mA current signal) from the conductivity measuring device in real time through its analog input channel (AI channel), and obtains the real-time conductivity value of the current working fluid after analog-to-digital conversion.

[0044] The built-in comparison logic module of the control unit continuously compares the real-time conductivity value with the preset recycling standard threshold. When the comparison result shows that the real-time conductivity value is less than or equal to the recycling standard threshold, it indicates that the content of soluble ionic impurities in the working fluid flowing through the measuring probe has been reduced to a permissible range for recycling. The control unit then generates a logical judgment result representing "meeting the recycling conditions," which serves as the direct prerequisite for triggering the generation of subsequent switching commands.

[0045] If the real-time conductivity value is greater than the recycling standard threshold, it is determined that the recycling conditions are not met, and the system is maintained or switched to discharge mode. In a specific embodiment of the present invention applied to the recycling of regenerated wastewater in thermal power plants, this comparison logic is built into the control logic configuration of the distributed control system (DCS), and operators can preset and revise the recycling standard threshold online at the operator station according to actual process requirements.

[0046] In some embodiments, generating a switching command and driving a switching valve to actuate when the recovery conditions are met, so as to introduce the working fluid to be processed into the recovery pipeline, includes: A control signal is output to the pneumatic actuator that is connected to the switching valve. The pneumatic actuator converts the control signal into a mechanical driving force, which drives the switching valve to switch between the open position of the recovery pipeline and the closed position of the recovery pipeline.

[0047] In this embodiment, the switching valve is installed at the branch connection between the main working fluid conveying pipeline and the recovery pipeline. The movable valve component (such as a ball, butterfly plate, or gate) inside the valve body is rigidly connected to the output shaft of a pneumatic actuator via a mechanical transmission assembly. In this specific embodiment, the pneumatic actuator is a field-installed pneumatic actuator, the core of which is a mechanical energy conversion device comprising a cylinder, piston, or diaphragm assembly. When the control unit generates a switching command representing "switching to recovery state" based on the judgment logic, this command is transmitted as an electrical control signal via an output channel (in this specific embodiment, the digital output (DO) channel of the distributed control system (DCS)) and a connecting cable to the pneumatic actuator located in the field.

[0048] Specifically, the control signal first drives the solenoid valve integrated on the pneumatic actuator. The solenoid valve then switches the direction of compressed air flow, introducing air pressure from the field air source into the corresponding chamber of the cylinder. The air pressure acts on the piston or diaphragm, converting the gas pressure energy into linear or rotational mechanical driving force. This mechanical driving force is directly transmitted to the valve stem of the switching valve through the output shaft, overcoming the friction and fluid pressure inside the valve, and driving the valve assembly to move to the preset working position corresponding to "opening the recovery pipeline," thereby opening the recovery pipeline. Conversely, when the recovery conditions are not met, the control system issues the opposite command, and the pneumatic actuator drives the switching valve to the closed position of "cutting off the recovery pipeline."

[0049] In some embodiments, obtaining the position status information of the switching valve and feeding it back to the control unit, and confirming the execution result of the switching command, includes: The mechanical position change is detected, and a feedback switch generates a contact signal representing that the switching valve has reached the target position as the position status information, and the contact signal is transmitted to the input interface.

[0050] In this embodiment, a feedback switch is directly mounted on the housing of the switching valve or its drive device (such as the aforementioned pneumatic actuator), and its internal moving detection component forms a physical follow-up connection with the movable mechanical components of the switching valve. When the switching valve undergoes a mechanical position change under the drive of the actuator and eventually reaches a preset target position (e.g., the fully open position corresponding to opening the recovery pipeline, or the fully closed position corresponding to cutting off the recovery pipeline), the linear or rotational displacement of the valve stem or the output shaft of the actuator will directly trigger the detection end of the feedback switch. This feedback switch is the feedback switch mounted on the pneumatic actuator in this specific embodiment of the invention, and its function is to directly convert the physical quantity of mechanical position into a change in electrical on / off state.

[0051] When the switching valve reaches the target position, the mechanical linkage mechanism inside the feedback switch triggers its electrical contacts to operate, for example, the normally open contact closes or the normally closed contact opens, thereby generating a contact signal that clearly indicates "valve is in position." This contact signal constitutes the position status information. This contact signal is then directly transmitted to the switch input interface circuit of the control unit via a signal cable laid in the field. In a specific embodiment of this invention applied to the recycling of regenerated wastewater in a thermal power plant, this input interface is the digital input (DI) channel of the distributed control system (DCS). The control unit can perceive the actual position of the switching valve in real time by detecting changes in the voltage level on this DI channel.

[0052] In some embodiments, the method further includes: The operation interface simultaneously provides a switching valve status indication area and a working medium status data real-time display area, showing the current open / closed status of the switching valve and the real-time status data of the working medium to be processed.

[0053] In a specific embodiment of this invention applied to the recycling of reclaimed wastewater in thermal power plants, the user interface is built on the operator station monitoring screen of the distributed control system (DCS). On this screen, the control system's configuration software displays two functionally independent areas. The switching valve status indication area uses a graphical method, for example, valve icons of different colors or shapes, to dynamically correlate with the actual position status signal fed back to the digital input (DI) channel by the switching valve.

[0054] When the control unit receives a contact signal from the field feedback switch and confirms that the switching valve has reached the target open or closed position, the change in this signal state is mapped to the operating interface in real time, driving the valve icon to display the corresponding open or closed visual effect, allowing operators to intuitively identify the current open / closed state of the switching valve. Simultaneously, the real-time display area for working fluid status data is linked to the control system's analog input (AI) channel. Real-time status data obtained from the conductivity measuring device, i.e., the real-time conductivity value of the working fluid, is continuously presented in this area in the form of dynamic numbers or trend curves. As a further optimization, this area can also simultaneously display a preset recovery standard threshold line for operators to compare.

[0055] By displaying the switching valve position status and working fluid quality data simultaneously on a single operating interface, this method allows operators to fully grasp the overall operating status of the automatic working fluid switching system from the control room without switching screens or going to the site, thereby significantly improving the system's monitorability and human-machine interaction efficiency.

[0056] Corresponding to the above-described automatic working fluid switching control method, this invention also proposes an automatic working fluid switching control device. Since the device embodiments of this invention correspond to the above-described method embodiments, details not disclosed in the device embodiments can be referred to the above-described method embodiments, and will not be repeated here.

The confirmation unit 24 is used to acquire the position status information of the switching valve and feed it back to the control unit to confirm the execution result of the switching command.

[0059] Furthermore, in one possible implementation of this disclosure, the determining unit 22 is further configured to: The conductivity value represented by the standard electrical signal is compared with a preset recycling standard threshold.
