Description

Technical Field

[0001] The embodiments of this specification belong to the technical field of aviation fuel blending, and in particular, to a system for blending fuel. Background Art

[0002] With the development of green transformation in civil aviation, the use of synthetic aviation fuel (SAF) has become an effective way to reduce emissions. According to the regulations of the Civil Aviation Administration of China and international common practices, synthetic hydrocarbon components (SHC) in aviation fuel cannot be directly added to aircraft for use. Instead, they must be blended with traditional jet fuel in a specified ratio to form a uniform synthetic hydrocarbon civil aviation fuel. Only after the test indicators meet the aircraft airworthiness requirements can they be added to aircraft for commercial use.

[0003] The existing blending method for synthetic hydrocarbon components and traditional jet fuel mainly relies on manual blending tanks, and there is a need to improve the stirring effect and blending ratio. Summary of the Invention

DETAILED DESCRIPTION

[0010] To make the purpose, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0011] The terms "including" and "having" and any variations thereof in this specification and claims and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units inherent to these processes, methods, products or apparatuses. Depending on the context, the word "if" as used herein may be interpreted as "at..." or "when..." or "in response to determining" or "in response to detecting".

[0012] As mentioned above, the existing blending method for civil aviation fuel containing synthetic hydrocarbons is mainly to manually calculate the total amount of components corresponding to each component based on the required total amount of civil aviation fuel containing synthetic hydrocarbons and the ratio of different components in the civil aviation fuel containing synthetic hydrocarbons, manually adjust each component tank to output the components to the blending tank according to the corresponding total amount of components, and use the stirring system set in the blending tank to mix and stir all the components to obtain civil aviation fuel containing synthetic hydrocarbons. However, this relatively manual blending method is affected by manual calculation errors, etc., which can easily lead to inaccurate total amounts of components output from each component tank to the blending tank, and thus cannot guarantee the acquisition of civil aviation fuel containing synthetic hydrocarbons with a precise blending ratio; on the other hand, it is also easily affected by the stirring effect of the blending tank, resulting in uneven blending between the components, and thus cannot guarantee whether the civil aviation fuel containing synthetic hydrocarbons meets the fuel filling needs of the aircraft.

[0013] Based on this, an embodiment of the present disclosure proposes a system for blending fuels, including a primary mixing and blending pipeline, a stirring mixer, and a controller. The primary mixing and blending pipeline is used to preliminarily mix the fuel components stored in each component tank to obtain a primary mixed blending fuel, and to convey the primary mixed blending fuel to the stirring mixer. The stirring mixer is used to stir the primary mixed blending fuel to obtain a target blending fuel, and to convey the target blending fuel to a storage tank for storage. The controller is used to control each component tank to convey the component to the primary mixing and blending pipeline according to the proportion of the component stored in each component tank in the target blending fuel, so that the proportion of the component in the primary mixed blending fuel is consistent with the target blending fuel.

[0014] In this way, the controller can be combined to control each component tank to transport components to the primary mixing and blending pipeline, so that the primary mixing and blending pipeline can be used to transport the obtained primary mixing and blending fuel to the stirring mixer, and then the stirring mixer can evenly blend the primary mixing and blending fuel to obtain the target blending fuel, and output it to the storage tank for storage; this method of controlling the blending of each component by the controller can more accurately control the blending ratio between the components than manual operation, and the use of the primary mixing and blending pipeline can ensure that the blending ratio of each component before stirring meets the requirements. Secondly, the stirring mixer can also be used to evenly stir the components whose blending ratio meets the requirements. Compared with the blending tank, it can better ensure the stability and uniformity of the fuel blending, and can reduce the investment cost caused by the technical transformation of the blending tank, making the fuel blending more economical.

[0015] See also Figure 1 , Figure 1 FIG. 1 shows a schematic diagram of a system for blending fuel according to some embodiments of the present disclosure. Figure 1As shown, a system 100 for blending fuel may include component tanks 101, a controller 102, a primary blending pipeline 103, a stirring mixer 104, and a storage tank 105. Here, the component tanks 101 can be used to store the various components of the blended fuel. For example, if the required blended fuel is civil aviation fuel containing synthetic hydrocarbons, the component tanks 101 can be divided into component tanks for storing traditional jet fuel components and component tanks for storing synthetic hydrocarbon components. Of course, the component tanks 101 can also be used to store various components for blending other types of fuels, and the number of component tanks 101 can be adjusted according to the type and quantity of components to be blended. The input end of the primary mixing and blending pipeline 103 can be connected to the output end of each component tank 101 respectively, and the output end of the primary mixing and blending pipeline 103 can be connected to the input end of the stirring mixer 104, which is used to perform preliminary mixing processing on the components delivered by each component tank 101 to obtain a primary mixed fuel, so as to ensure that the blending ratio of each component before stirring meets the requirements, and the primary mixed fuel can be delivered to the stirring mixer 104. The stirring mixer 104 can be, but is not limited to, a rotary jet agitator well known in the art. The output end of the stirring mixer 104 is connected to the storage tank 105, which is used to uniformly stir the primary mixed fuel to obtain a target blended fuel. For example, when the components in the primary mixed fuel include traditional jet fuel components and synthetic hydrocarbon components, the target blended fuel is a civil aviation fuel containing synthetic hydrocarbons. The storage tank 105 can be used to store the obtained target blended fuel and transfer the target blended fuel to the aircraft after passing the inspection.

[0016] It should be noted that in some embodiments of the present disclosure, the inner diameter of the primary mixing and blending pipeline 103 is greater than the sum of the inner diameters of the pipelines between the component tanks 101 and the primary mixing and blending pipeline 103. This design structure effectively reduces the flow rate of each component when passing through the primary mixing and blending pipeline 103, which not only extends the residence time of each component in the primary mixing and blending pipeline 103, but also reduces the local concentration difference of each component in the primary mixing and blending pipeline 103, thereby ensuring that the blending ratio of each component before stirring better meets the requirements.

[0017] The controller 102 may be, but is not limited to, a programmable logic controller (PLC) known in the art. The controller 102 may establish a communication connection with each component tank 101 to control each component tank 101 storing the corresponding component to output the component to the primary blending pipeline based on the desired ratio of each component in the target blended fuel, so that the ratio of the components in the primary blended fuel obtained by the primary blending pipeline is consistent with the desired ratio of the components in the target blended fuel.

[0018] It is understood that the controller 102 may also establish a communication connection with the aforementioned mixer 104 to control the mixer 104 to stir the primary blended fuel according to the set stirring operating parameters, thereby further ensuring the blending effect of the target blended fuel. Of course, the controller 102 may also establish a communication connection with a detection device disposed on the pipeline between each component tank 101 and the primary blending pipeline 103 to detect the corresponding component data transported from each component tank 101 to the primary blending pipeline 103 in real time, thereby more accurately controlling the blending ratio of each component in the primary blending pipeline 103, but the present invention is not limited to this.

[0019] In this way, the controller can be combined to control the component tanks to transport components to the primary mixing and blending pipeline, so that the primary mixing and blending pipeline can be used to transport the obtained primary mixing and blending fuel to the stirring mixer, and then the stirring mixer can evenly blend the primary mixing and blending fuel to obtain the target blending fuel, and output it to the storage tank for storage; this method of controlling the blending of each component by the controller can more accurately control the blending ratio between the components than manual methods, and the use of the primary mixing and blending pipeline not only increases the flexibility of the production process, but also improves the mixing uniformity of the components and ensures that the blending ratio of the components before stirring meets the requirements. Secondly, the stirring mixer can also be used to evenly stir the components whose blending ratio meets the requirements, which can better ensure the stability and uniformity of fuel blending than the blending tank, and can also reduce the workload of the stirring mixer (such as local overheating or mechanical stress concentration) and equipment wear, and can reduce the investment cost caused by the technical transformation of the blending tank and extend the service life of the equipment, making fuel blending more economical.

[0020] See also Figure 2 , Figure 2 1 shows a flow chart of a control method of a controller in a system for blending fuel according to some embodiments of the present disclosure. Figure 1 The controller in the fuel blending system shown is executed. The controller establishes a communication connection with each component tank storing the blended fuel components and can send control signals to each component tank to deliver or stop the delivery of the component. Each component tank may be equipped with a control circuit or communication circuit for receiving the control signal from the controller, and may also be equipped with a valve that can control the state of the valve after receiving the control signal to enable or stop the delivery of the corresponding component.

[0021] In some embodiments, the controller may also obtain manually input blending parameters of the target blended fuel, or pre-store the blending parameters of the target blended fuel. The blending parameters may include, but are not limited to, the various components contained in the target blended fuel and the proportions of the various components in the target blended fuel, such as volume ratios, weight ratios, etc. The controller may select the component tanks storing the corresponding components based on the various components contained in the target blended fuel, and may also determine the total amount of components corresponding to each component tank based on the proportions of the various components in the target blended fuel, such as the total volume or total mass of the components output by each component tank to the primary blending pipeline, and determine the control signal sent to each component tank based on the total amount of components. Here, the control signal may be the valve opening of each component tank and the corresponding valve opening time. Of course, in some embodiments, the controller may pre-set the blending time, use the blending time as the valve opening time for each component tank, and determine the valve opening of each component tank based on the blending time and the aforementioned total amount of components, but the present invention is not limited to this.

[0022] like Figure 2 As shown, at block 202, method 200 may determine the total amount of components to be output from each component tank based on the proportion of the components stored in each component tank in the target blended fuel. In some embodiments, the target blended fuel may be a synthetic hydrocarbon-containing civil aviation fuel, and the components contained in the synthetic hydrocarbon-containing civil aviation fuel may be a conventional jet fuel component and a synthetic hydrocarbon component. The proportion of the conventional jet fuel component in the synthetic hydrocarbon-containing civil aviation fuel is different from the proportion of the synthetic hydrocarbon component in the synthetic hydrocarbon-containing civil aviation fuel, and the sum of the proportion of the conventional jet fuel component and the proportion of the synthetic hydrocarbon component is 1.

[0023] Here, the controller may also determine the total amount of components delivered by each component tank to the primary mixing and blending pipeline by calculation or table lookup based on the proportion of the components stored in each component tank in the target blended fuel and the total amount required for the target blended fuel. It will be appreciated that when the total amount required for the target blended fuel is expressed as a total volume, the total amount of components delivered by each component tank to the primary mixing and blending pipeline may be the total volume of the components. Alternatively, when the total amount required for the target blended fuel is expressed as a total mass, the total amount of components delivered by each component tank to the primary mixing and blending pipeline may be the total mass of the components.

[0024] At block 204, method 200 may control each component tank to deliver the component to the primary mixing and blending pipeline according to the corresponding component total amount. In some embodiments, the controller may determine the valve opening of each component tank for the blending duration based on the component total amount corresponding to each component tank and the blending duration required for the target blended fuel, and transmit a control signal generated by the blending duration and the valve opening corresponding to each component tank to the corresponding component tank, so that after receiving the control signal, each component tank delivers the component to the primary mixing and blending pipeline according to the corresponding valve opening and the blending duration. Of course, the controller may also determine the valve opening time of each component tank for the corresponding preset valve opening based on the component total amount corresponding to each component tank and the preset valve opening of each component tank, and transmit a control signal generated by the preset valve opening and the valve opening time corresponding to each component tank to the corresponding component tank, so that after receiving the control signal, each component tank delivers the component to the primary mixing and blending pipeline according to the corresponding valve opening time and the preset valve opening.

[0025] In this way, the blending ratio between the components can be controlled more accurately than manual labor, and the use of the initial mixing pipeline can not only increase the flexibility of the production process, but also improve the mixing uniformity of the components and ensure that the blending ratio of the components before stirring meets the requirements. Secondly, the stirring mixer can be used to evenly stir the components whose blending ratio meets the requirements. Compared with the blending tank, it can better ensure the stability and uniformity of the fuel blending, and can also reduce the workload of the stirring mixer (such as local overheating or mechanical stress concentration) and equipment wear, and can reduce the investment cost caused by the technical transformation of the blending tank and extend the service life of the equipment, making fuel blending more economical.

[0026] In some embodiments, each component tank has a corresponding flow detection device, and the flow detection device is provided on the corresponding component tank and the primary mixing pipeline; and The steps at block 204 also include: determining a pipeline flow ratio between pipeline flows of each component tank based on detection values of each flow detection device; Determine whether pipeline flow ratios are consistent with component proportions; and In response to determining that the pipeline flow rate ratio is consistent with the component ratio, the primary blending pipeline is controlled to deliver the primary blended fuel to the stirring mixer.

[0027] In addition to the aforementioned primary mixing and blending pipeline, stirring mixer, and controller, the system for blending fuels in some embodiments of the present disclosure may also include a flow detection device corresponding to each component tank. The flow detection device may be, but is not limited to, a flow meter well known in the art, and may be disposed on the pipeline between the corresponding component tank and the primary mixing and blending pipeline, and is not limited to one or more. The controller may also establish a communication connection with the flow detection device corresponding to each component tank, and may send a control signal to each flow detection device so that each flow detection device, after receiving the control signal, collects the pipeline flow (also understood as the pipeline component flow) between the corresponding component tank and the primary mixing and blending pipeline, and feeds the collected component flow back to the controller in real time, so that the controller can combine all pipeline flows to determine whether the components output from each component tank to the primary mixing and blending pipeline in real time meet the blending ratio requirements between the components, thereby ensuring the real-time blending accuracy of all components in the primary mixing and blending pipeline during the primary mixing.

[0028] See also Figure 3 , Figure 3 Another structural diagram of a system for blending fuel according to some embodiments of the present disclosure is shown. Figure 3 As shown, the system 300 for blending fuel may include a component tank 301 , a controller 302 , a primary blending pipeline 303 , a stirring mixer 304 , a storage tank 305 , and a flow meter 306 . Here, the flow meter 306 can be set on the pipeline between each component tank 301 and the primary mixing and blending pipeline 303. For example, taking the required blending fuel as civil aviation fuel containing synthetic hydrocarbons, the component tanks 301 can be divided into component tanks for storing traditional jet fuel components and component tanks for storing synthetic hydrocarbon components. The flow meter 306 can be divided into a flow meter 306 set on the pipeline between the component tank 301 for storing traditional jet fuel components and the primary mixing and blending pipeline 303, so as to collect the pipeline flow between the component tank 301 for storing traditional jet fuel components and the primary mixing and blending pipeline 303; and a flow meter 306 set on the pipeline between the component tank 301 for storing synthetic hydrocarbon components and the primary mixing and blending pipeline 303, so as to collect the pipeline flow between the component tank 301 for storing synthetic hydrocarbon components and the primary mixing and blending pipeline 303.

[0029] Here, when the controller controls each component tank to output the component to the primary mixing and blending pipeline according to the corresponding total amount of the component, it can also receive the detection value collected by each flow detection device in real time, and use the ratio of all detection values as the pipeline flow ratio corresponding to each component tank in real time when outputting the component. It can be understood that the detection value collected by each flow detection device can be, but is not limited to, determined according to the number of flow detection devices set between each component tank and the primary mixing and blending pipeline. For example, when the number of flow detection devices set between each component tank and the primary mixing and blending pipeline is one, the flow value collected by each flow detection device can be used as the detection value; when the number of flow detection devices set between each component tank and the primary mixing and blending pipeline is greater than one, the average result of the flow values of all flow detection devices corresponding to each component tank can be, but is not limited to, used as the corresponding detection value, and is not limited to this.

[0030] It should be noted that in order to ensure the consistency of the detection values collected by each flow detection device, the controller can also simultaneously obtain the detection values collected by each flow detection device at a specified time interval, and can also combine the historical pipeline flow to determine whether the detection values collected by each flow detection device are valid. Invalid detection values can be re-acquired to further ensure the real-time blending effect of the components output by each component tank 301 during the entire blending process.

[0031] Then, after determining the pipeline flow ratio corresponding to each component tank in real time when outputting the component, the controller can also judge whether the components output by each component tank to the primary mixing and blending pipeline in real time meet the blending ratio requirements by comparing whether the pipeline flow ratio is consistent with the component ratio between the components stored in the above-mentioned component tanks. Here, when the pipeline flow ratio is consistent with the component ratio between the components stored in the component tanks, it indicates that the components currently output by each component tank to the primary mixing and blending pipeline meet the blending ratio requirements, and then the primary mixing and blending pipeline can be used to transport the primary mixed fuel obtained by the primary mixing of all components to the stirring mixer. In addition, the controller can also maintain the output component status of each component tank, for example, but not limited to maintaining the valve opening of each component tank, and judge whether the components output by each component tank at different times in the future meet the blending ratio requirements based on the detection values collected again by each flow detection device, until each component tank outputs the corresponding total amount of components to the primary mixing and blending pipeline.

[0032] When the pipeline flow ratio is inconsistent with the component ratio between the components stored in each component tank, it indicates that the components currently output by each component tank to the primary mixing pipeline do not meet the blending ratio requirements. Here, the controller can also adjust the component flow rate output by each component tank to the primary mixing pipeline in real time by changing the valve opening of each component tank according to the pipeline flow ratio and the pre-set blending time, and try to reduce the adjustment frequency of each component tank. For example, if the set blending time cannot be changed, the controller can determine that there is a large abnormality in the pipeline flow when the pipeline flow ratio is greater than the component ratio between the components stored in each component tank, and reduce the component flow rate of all component tanks with the abnormality by reducing the valve opening; and can also determine that there is a small abnormality in the pipeline flow when the pipeline flow ratio is less than the component ratio between the components stored in each component tank, and increase the component flow rate of all component tanks with the abnormality by increasing the valve opening.

[0033] For another example, the set blending time can be changed within a specified time fluctuation range. The controller can also determine that there is a minor abnormality in the pipeline flow of at least one component tank when the pipeline flow ratio is greater than the component ratio between the components stored in each component tank, and then reduce and adjust the blending time within the specified time fluctuation range, and increase the valve opening according to the adjusted blending time, thereby increasing the component flow rate outputted next by all the component tanks with the abnormality; and can also determine that there is a major abnormality in the pipeline flow of at least one component tank when the pipeline flow ratio is less than the component ratio between the components stored in each component tank, and then increase and adjust the blending time within the specified time fluctuation range, and reduce the valve opening according to the adjusted blending time, thereby reducing the component flow rate outputted next by all the component tanks with the abnormality.

[0034] In some embodiments, each component tank has at least two corresponding flow detection devices, and the control method of the controller further includes: Obtain the detection values of all flow detection devices corresponding to each component tank; Determining whether the pipeline flow of the corresponding component tank is normal based on the standard deviation of the detection values of all flow detection devices corresponding to each component tank; and In response to determining that the pipeline flow of any component tank is normal, a weighted sum of the detection values of all flow detection devices corresponding to the corresponding component tank is used as the pipeline flow value of the corresponding component tank.

[0035] To ensure that the pipeline flow rate of each component tank during real-time component delivery is not affected by electromagnetic signal interference, multiple flow detection devices may be installed at different locations in the pipeline between each component tank and the primary mixing and blending pipeline, but are not limited to these devices. The detection values collected by these multiple flow detection devices can be used to more accurately determine the pipeline flow rate of each component tank during real-time component delivery. In some embodiments of the present disclosure, the flow detection devices installed at different locations in the pipeline between each component tank and the primary mixing and blending pipeline can be of different types, so that the determined pipeline flow rate is more universal and reliable.

[0036] Here, when the controller determines the pipeline flow rate of each component tank when it is outputting components in real time, it can also obtain the detection values collected by all flow detection devices between each component tank and the initial mixing pipeline, and calculate the standard deviation of all detection values corresponding to each component tank respectively, so as to determine whether the pipeline flow rate of each component tank when it is currently outputting components is abnormal, that is, whether it is affected by electromagnetic signal interference, etc. through the calculation result of the standard deviation. It is understandable that when the standard deviation corresponding to any component tank is less than or equal to the preset standard deviation threshold, it indicates that the detection values of all flow detection devices corresponding to the component tank are normal, that is, the pipeline flow rate of the component tank is normal, and then the detection values of all flow detection devices corresponding to the component tank can be weighted and summed according to, but not limited to, preset weight parameters, and the weighted summation result is used as the pipeline flow rate of the component tank when it is currently outputting components.

[0037] When the standard deviation corresponding to any component tank is greater than a preset standard deviation threshold, it indicates that the detection values of all flow detection devices corresponding to the component tank are abnormal, that is, the pipeline flow of the component tank is abnormal. Then, at least one abnormal value can be eliminated from all the detection values of the component tank, and the difference between the abnormal value and the remaining detection values is large. Then, the standard deviation of all remaining detection values can be calculated again. If the standard deviation obtained again is less than or equal to the preset standard deviation threshold, it indicates that all the remaining detection values of the corresponding component tank are normal. Then, the preset weight parameters of all flow detection devices corresponding to the remaining detection values can be adjusted, and the weighted summation calculation of all the remaining detection values can be performed according to the adjusted weight parameters to obtain the pipeline flow of the component tank when the component is currently outputting the component. If the standard deviation obtained again is still greater than the preset standard deviation threshold, it indicates that all the detection values of the corresponding component tank are abnormal. It is possible that there is an abnormality in the pipeline between the component tank and the primary mixing pipeline. Then, a pipeline replacement signal can be sent to the terminal to remind the operator to perform pipeline replacement processing until the standard deviation determined for all the detection values of the component tank is less than or equal to the preset standard deviation threshold.

[0038] In some embodiments, each component tank has a corresponding flow rate control device, and the flow rate control device is provided between the corresponding component tank and the primary mixing pipeline; the control method of the controller further includes: Determine the component flow rate corresponding to each component tank based on the total amount of components in each component tank and the blending time of the target blended fuel; Based on the component flow rates corresponding to the component tanks and the first neural network, predicting control parameters of the corresponding flow rate control device; and Control each flow rate control device to output according to the corresponding control parameters so that each component tank can transport the component to the primary mixing pipeline according to the corresponding total amount of the component.

[0039] In addition to the aforementioned primary mixing and blending pipeline, stirring mixer, and controller, the system for blending fuels in some embodiments of the present disclosure may also include a flow rate control device corresponding to each component tank. The flow rate control device may be, but is not limited to, a variable frequency oil pump well known in the art, or a combination structure of a variable frequency oil pump and a flow control valve (this component method can effectively improve the control accuracy of the flow rate and effectively reduce the overall power consumption compared to setting up a variable frequency oil pump alone), and is set on the pipeline between the corresponding component tank and the primary mixing and blending pipeline. The controller can also establish a communication connection with the flow rate control device corresponding to each component tank, and can send a control signal to each flow rate control device so that each flow rate control device adjusts the component flow rate between the corresponding component tank and the primary mixing and blending pipeline after receiving the control signal. Here, the flow rate control device is taken as an example of a combination structure of a variable frequency oil pump and a flow control valve. The control signal may include the working state parameters of the variable frequency oil pump and the valve opening of the flow control valve, but is not limited to this. Of course, the aforementioned flow detection device may be further provided on the pipeline between each component tank and the primary mixing pipeline, and the flow rate control device may also be provided between each component tank and the flow detection device, and the present invention is not limited thereto.

[0040] See also Figure 4 , Figure 4 Another structural diagram of a system for blending fuel according to some embodiments of the present disclosure is shown. Figure 4As shown, a system 400 for blending fuel may include component tanks 401, a controller 402, a primary blending pipeline 403, a stirring mixer 404, a storage tank 405, a flow meter 406, a variable frequency oil pump 407, and a control valve 408. Here, the variable frequency oil pump 407 and the control valve 408 together constitute a flow rate control device, which may be disposed on a pipeline between each component tank 401 and the primary blending pipeline 403. For example, in the case where the desired blended fuel is civil aviation fuel containing synthetic hydrocarbons, the component tanks 401 may be divided into component tanks for storing conventional jet fuel components and component tanks for storing synthetic hydrocarbon components. The variable frequency oil pump 407 may be divided into a variable frequency oil pump 407 disposed on a pipeline between the component tank 401 for storing conventional jet fuel components and the primary blending pipeline 403, and a variable frequency oil pump 407 disposed on a pipeline between the component tank 401 for storing synthetic hydrocarbon components and the primary blending pipeline 403. The control valve 408 can be divided into a control valve 408 arranged on the pipeline between the component tank 401 for storing traditional jet fuel components and the primary mixing and blending pipeline 403, and a control valve 408 arranged on the pipeline between the component tank 401 for storing synthetic hydrocarbon components and the primary mixing and blending pipeline 403.

[0041] The controller 402 can also establish communication connections with each variable frequency oil pump 407 and each control valve 408 to control the flow rate of the components delivered by each component tank 401 along the pipeline between the corresponding component tank and the primary mixing and blending pipeline 403 according to the blending requirements of the target blended fuel. This ensures that each component tank 401 meets the blending requirements while also ensuring uniformity and smoothness of the blending between the components. Of course, when each component tank 401 outputs the components to the primary mixing and blending pipeline 403 in real time, the controller 402 can also adjust the flow rate of the components output by each component tank 401 in real time by controlling each variable frequency oil pump 407 and each control valve 408 according to the detection values of each flow detection device 406, thereby ensuring the real-time blending ratio of the components output by each component tank 401 to the primary mixing and blending pipeline.

[0042] Here, before controlling each component tank to output the component to the primary mixing and blending pipeline according to the corresponding total amount of the component, the controller can also determine the component flow rate corresponding to each component tank when outputting the component based on the total amount of the component in each component tank and the blending time required for the target blended fuel, for example, but not limited to, the ratio between the total amount of the component in each component tank and the blending time is used as the component flow rate corresponding to each component tank when outputting the component. Of course, in some embodiments of the present disclosure, the corresponding component flow rate can also be directly queried according to the fuel type of the target blended fuel, so as to further ensure the universality and effectiveness of the flow rate of each component by combining manual blending experience and big data analysis. It should be noted that the control signal sent by the controller to each component tank at this time can control the valve opening of each component tank to remain at the maximum, so as to achieve more precise control of the flow rate of the component output by each component tank through the flow rate control device.

[0043] Next, after determining the component flow rate of each component tank as it outputs the component, the controller can also input the component flow rate corresponding to each component tank into the first neural network to effectively reduce the overall power consumption of the flow rate control device. Using an intelligent algorithm, the controller predicts the control parameters for each flow rate control device when the overall power consumption is minimized. Here, using the flow rate control device as an example, a combination of a variable frequency oil pump and a flow control valve, the control parameters can include, but are not limited to, the start and stop parameters of the variable frequency oil pump and the opening parameters of the flow control valve.

[0044] It can be understood that the first neural network can be a physical information neural network, and its architecture is divided into a parameter prediction neural network including an input layer, a hidden layer and an output layer, and a power consumption calculation physical model. The parameter prediction neural network can be used to predict the control parameters of each corresponding flow rate control device based on the component flow rate corresponding to each component tank input, and the power consumption calculation physical model can be used to calculate the overall power consumption of all flow rate control devices based on the component flow rate corresponding to each component tank and the control parameters of each corresponding flow rate control device predicted by the parameter prediction neural network. When training the first neural network, the training set includes component flow rate samples for each component tank, and the loss function can be set as the sum of the overall power consumption and parameter constraint loss (e.g., including the constrained minimum value corresponding to the component flow rate and the constrained range corresponding to the control parameter) obtained by calculating the power consumption calculation physical model. The component flow rate samples for each component tank are input into the parameter prediction neural network to predict the control parameters of each corresponding flow rate control device. The power consumption calculation physical model then calculates the overall power consumption of all flow rate control devices based on the component flow rate samples for each component tank and the control parameters of each corresponding flow rate control device. The loss function then calculates the total loss based on the overall power consumption of all flow rate control devices, the component flow rate samples for each component tank, and the control parameters of each corresponding flow rate control device. The gradient of the total loss with respect to the weights of the parameter prediction neural network is calculated, and the optimizer is used to update the weights of the parameter prediction neural network to minimize the total loss until the loss converges. After the first neural network completes training, it can accurately predict the control parameters corresponding to each flow rate control device when the overall power consumption is minimized based on the component flow rates corresponding to each component tank input.

[0045] Then, after predicting the control parameters corresponding to each flow rate control device, the controller can also control each flow rate control device to output according to the corresponding control parameters, so that each component tank delivers the component to the primary mixing pipeline according to the corresponding total amount of the component.

[0046] Of course, in some embodiments of the present disclosure, when each component tank outputs a component to the primary mixing and blending pipeline in real time, if it is necessary to adjust the flow rate of the component output from each component tank to the primary mixing and blending pipeline, the component flow rate required for adjusting the flow rate can be input into the first neural network mentioned above, and the corresponding flow rate control device can be controlled according to the re-predicted control parameters, and the present invention is not limited to this.

[0047] In some embodiments, each component tank has a corresponding pressure detection device, and the pressure detection device is provided between the corresponding component tank and the primary mixing pipeline; the control method of the controller further includes: determining whether the injection pressure of the corresponding component tank is abnormal based on the detection value of each pressure detection device; and In response to determining that the injection pressure of any component tank is abnormal, the control parameters of the corresponding flow rate control device are adjusted based on the detection value of the corresponding pressure detection device and the preset pressure threshold, and the corresponding flow rate control device is controlled to output according to the adjusted control parameters, so that the fuel components in each component tank are delivered to the primary mixing pipeline by injection.

[0048] In addition to the aforementioned primary mixing and blending pipeline, stirring mixer, and controller, the system for blending fuels in some embodiments of the present disclosure may also include a pressure detection device corresponding to each component tank. The pressure detection device may be, but is not limited to, a pressure transmitter known in the art, and may be disposed on the pipeline between the corresponding component tank and the primary mixing and blending pipeline. The controller may also establish a communication connection with the pressure detection device corresponding to each component tank, and may send a control signal to each pressure detection device so that each pressure detection device, after receiving the control signal, collects the injection pressure (also understood as the pipeline component pressure) between the corresponding component tank and the primary mixing and blending pipeline, and feeds the collected injection pressure back to the controller in real time, so that the controller can determine whether the component output by each component tank enters the primary mixing and blending pipeline in the form of a spray, thereby ensuring the real-time mixing effect of the components output by each component tank to the primary mixing and blending pipeline. Of course, the aforementioned flow detection device and flow rate control device may also be disposed on the pipeline between each component tank and the primary mixing and blending pipeline, and the pressure detection device may also be disposed between the flow detection device and the primary mixing and blending pipeline, but is not limited thereto.

[0049] See also Figure 5 , Figure 5 Another structural diagram of a system for blending fuel according to some embodiments of the present disclosure is shown. Figure 5 As shown, the system 500 for blending fuel may include at least a component tank 501, a controller 502, a primary blending pipeline 503, a stirring mixer 504, a storage tank 505, a flow meter 506, a variable frequency oil pump 507, a control valve 508 and a pressure transmitter 509. Here, the pressure transmitter 509 can be installed on the pipeline between each component tank 501 and the primary mixing and blending pipeline 503. For example, taking the required blending fuel as civil aviation fuel containing synthetic hydrocarbons, the component tanks 501 can be divided into component tanks for storing traditional jet fuel components and component tanks for storing synthetic hydrocarbon components. The pressure transmitter 509 can be divided into a pressure transmitter 509 installed on the pipeline between the component tank 501 for storing traditional jet fuel components and the primary mixing and blending pipeline 503, so as to collect the injection pressure between the component tank 501 for storing traditional jet fuel components and the primary mixing and blending pipeline 503; and a pressure transmitter 509 installed on the pipeline between the component tank 501 for storing synthetic hydrocarbon components and the primary mixing and blending pipeline 503, so as to collect the injection pressure between the component tank 501 for storing synthetic hydrocarbon components and the primary mixing and blending pipeline 503.

[0050] Here, while controlling each component tank to output the corresponding total amount of the component to the primary mixing and blending pipeline, the controller can also obtain the detection values collected by each pressure detection device in real time and compare the detection values of each pressure detection device with a preset pressure threshold to determine whether the injection pressure of the corresponding component tank is abnormal. It can be understood that the injection pressure is the pipeline component pressure of each component output to the primary mixing and blending pipeline. Only when the injection pressure exceeds the preset pressure threshold can the component enter the primary mixing and blending pipeline in the form of a spray. This method of increasing the contact surface between the components can effectively ensure the real-time mixing effect of the components.

[0051] When the difference between the detection value of any pressure detection device and the preset pressure threshold does not exceed the preset pressure range, it indicates that the injection pressure of the corresponding component tank is normal, and the corresponding component tank can be controlled to continue to output according to the current component output mode; when the difference between the detection value of any pressure detection device and the preset pressure threshold exceeds the preset pressure range, it indicates that the injection pressure of the corresponding component tank is abnormal, and the controller can then determine the control parameter adjustment value based on the difference between the detection value and the preset pressure threshold, for example, but not limited to, querying the control parameter adjustment value corresponding to the current difference in the preset pressure difference value-control parameter adjustment value correspondence, and adjusting the corresponding control parameter based on the control parameter adjustment value. It should be noted that the preset pressure difference value-control parameter adjustment value correspondence can only be queried in conjunction with the preset pressure difference value-control parameter adjustment value correspondence when the pressure difference value is within a certain range, and the multiple control parameter adjustment values in the preset pressure difference value-control parameter adjustment value correspondence are all within the specified adjustment range to avoid causing large adjustments to the control parameters, thereby affecting the overall blending effect due to large fluctuations in component output.

[0052] Then, after adjusting the control parameters corresponding to each flow rate control device, the controller can also control each flow rate control device to output according to the adjusted control parameters, so that each component tank delivers the component to the primary mixing pipeline according to the corresponding total amount of the component.

[0053] In some embodiments, the system for blending fuel may further include a gas chromatography device for detecting the target blended fuel, and the control method of the controller may further include: Obtaining a gas chromatography analysis result of the target blended fuel based on a gas chromatography device, and predicting an air-fuel ratio of the target blended fuel based on the gas chromatography analysis result of the target blended fuel and a second neural network; Determining whether the air-fuel ratio of the target blended fuel is abnormal; In response to determining that the air-fuel ratio of the target blended fuel is abnormal, adjusting the total amount of components in each component tank based on the air-fuel ratio of the target blended fuel and a preset air-fuel ratio threshold; and Control each component tank to deliver the components to the primary mixing pipeline according to the adjusted total amount of components.

[0054] Because the content of the components output from each component tank to the primary blending pipeline is prone to fluctuation, this can easily lead to deviations in the content of different components in the target blended fuel, thereby affecting the combustion performance of the target blended fuel. Therefore, in addition to the aforementioned primary blending pipeline, stirring mixer, and controller (which may also include a flow detection device, flow rate control device, and pressure detection device), the fuel blending system of some embodiments of the present disclosure may also include a gas chromatograph. This gas chromatograph may be, but is not limited to, a gas chromatograph analyzer known in the art. The controller can also establish a communication connection with the gas chromatography device. After the target blended fuel is stored in the storage tank, it can send a control signal to the gas chromatography device to cause the gas chromatography device to analyze the target blended fuel extracted from the storage tank to obtain the actual component content in the target blended fuel. For example, when the target blended fuel is civil aviation fuel containing synthetic hydrocarbons, the corresponding component content may include olefin content, aromatics content, and sulfur content. The actual component content can be fed back to the controller so that the controller can determine whether the actual combustion effect of the target blended fuel meets the requirements, thereby providing guarantee for the subsequent use of the target blended fuel.

[0055] Here, after the agitator mixer outputs the target blended fuel to the storage tank, the controller may extract a small amount of the target blended fuel from the storage tank and place it in a gas chromatograph for analysis. Alternatively, a small amount of the target blended fuel may be manually extracted from the storage tank and placed in a gas chromatograph for analysis, thereby obtaining the component content analyzed by the gas chromatograph. Of course, the analysis configuration of the gas chromatograph in some embodiments of the present disclosure is conventional in the art and will not be elaborated upon here.

[0056] Then, after obtaining the component content of the target blended fuel, the controller may also input the component content of the target blended fuel into the second neural network to predict the air-fuel ratio corresponding to the target blended fuel through an intelligent algorithm.

[0057] It is understood that the second neural network can be a fully connected neural network, whose architecture includes an input layer, a hidden layer, and an output layer, capable of predicting the air-fuel ratio of a corresponding blended fuel based on the component content of the input blended fuel. When training the second neural network, the training set includes samples of the component content of different blended fuels and actual air-fuel ratio samples of each blended fuel. The loss function can be configured to calculate the mean squared error between the predicted air-fuel ratio and the corresponding actual air-fuel ratio samples. The corresponding air-fuel ratio is predicted based on the component content samples of the input blended fuels. The loss function then calculates a total loss based on the predicted air-fuel ratio and the actual air-fuel ratio samples of the corresponding blended fuels. The gradient of the total loss with respect to the weights of the second neural network is calculated, and the weights of the second neural network are updated using an optimizer to minimize the total loss until the maximum number of training rounds is reached. After the second neural network completes training, it can accurately predict the air-fuel ratio of the corresponding target blended fuel based on the component content of the input target blended fuel.

[0058] When the difference between the air-fuel ratio of the target blended fuel and the preset air-fuel ratio threshold does not exceed the preset ratio range, it indicates that the air-fuel ratio of the currently blended target blended fuel is normal, that is, the combustion effect of the target blended fuel meets the requirements, and then each component tank can be controlled to continue outputting according to the current component output method, and the component content analyzed by the gas chromatography device can be obtained again at a certain time interval.

[0059] When the difference between the air-fuel ratio of the target blended fuel and the preset air-fuel ratio threshold exceeds the preset ratio range, it indicates that the air-fuel ratio of the currently blended target blended fuel is abnormal, that is, the combustion effect of the target blended fuel does not meet the requirements. The controller can then adjust the total amount of components in each component tank based on the air-fuel ratio of the target blended fuel and the preset air-fuel ratio threshold. For example, but not limited to, the air-fuel ratio of the target blended fuel, the preset air-fuel ratio threshold, the component types contained in each component tank, and the corresponding total amount of components are input into the third neural network to more accurately predict the adjusted total amount of components corresponding to each component tank through an intelligent algorithm.

[0060] It can be understood that the third neural network in some embodiments of the present disclosure may be a multi-branch fusion neural network, whose architecture includes an input encoding layer, a feature fusion layer, and an output layer, and can predict the adjusted total amount of components corresponding to each component tank based on the input air-fuel ratio of the blended fuel, a preset air-fuel ratio threshold, the component types contained in each component tank, and the corresponding total amount of components. When training the third neural network, the training set includes real air-fuel ratio samples of different blended fuels, a preset air-fuel ratio threshold, the component types of the corresponding component tanks, the component total amount samples of the corresponding component tanks, and the adjusted total amount labels of the corresponding component tanks. The loss function can be set to calculate the mean square error between the predicted adjusted total amount of components corresponding to each component tank and the adjusted total amount labels of the corresponding component tanks, the difference between the sum of the predicted adjusted total amount of components corresponding to each component tank and the sum of the adjusted total amount labels of the corresponding component tanks, and the sum of the squares of the difference between the real air-fuel ratio samples and the preset air-fuel ratio threshold, and then calculate the loss function. Based on the input real air-fuel ratio sample of the blended fuel, the preset air-fuel ratio threshold, the component type of each component tank and the component total amount sample of each component tank, the adjusted component total amount corresponding to each component tank is predicted. Then, the loss function calculates the total loss based on the predicted adjusted component total amount corresponding to each component tank, the adjusted component total amount label of each component tank, the real air-fuel ratio sample of the corresponding blended fuel and the preset air-fuel ratio threshold. The weight of the third neural network is updated by the optimizer by calculating the gradient of the total loss with respect to the weight of the third neural network to minimize the total loss until the maximum number of training rounds is reached. After the third neural network completes training, it can accurately predict the adjusted component total amount corresponding to each component tank based on the input air-fuel ratio of the target blended fuel, the preset air-fuel ratio threshold, the component type contained in each component tank and the corresponding component total amount.

[0061] Then, after obtaining the adjusted total amount of components in each component tank, the controller can also control each component tank to transport the components to the primary mixing pipeline according to the adjusted total amount of components, such as adjusting the valve opening or valve opening time of each component tank to ensure the overall combustion effect of the target blended fuel.

[0062] In some embodiments, the control method of the controller further includes: Obtaining pipeline parameters of the primary mixing and blending pipeline, and determining operating parameters of the stirring mixer based on the pipeline parameters of the primary mixing and blending pipeline; and The stirring mixer is controlled to uniformly blend the primary mixed fuel according to corresponding working parameters to obtain the target blended fuel.

[0063] Since the components of different target blending fuels enter the primary mixing and blending pipeline, the pipeline parameters of the corresponding primary mixing and blending fuels output by the primary mixing and blending pipeline are different. In order to ensure that the stirring mixer has a more suitable stirring effect for different blending fuels, the operating parameters required by the stirring mixer can also be determined in combination with the pipeline parameters of the primary mixing and blending pipeline.

[0064] Here, after the primary mixing and blending pipeline outputs the primary mixed fuel to the stirring mixer, the controller can also, but is not limited to, obtain the pipeline parameters of the primary mixing and blending pipeline through a detection device set in the primary mixing and blending pipeline. For example, when the detection device is a pressure detection device, the corresponding pipeline parameter can be the pipeline pressure of the primary mixed fuel output by the primary mixing and blending pipeline. For example, when the detection device is a viscosity detection device, the corresponding pipeline parameter can be the oil viscosity of the primary mixed fuel output by the primary mixing and blending pipeline. The controller is not limited to the types of detection devices listed above, and can use the working requirements set by the stirring mixer and the pipeline parameters to determine the corresponding working parameters.

[0065] For example, taking the pipeline parameter of the oil viscosity of the primary mixed fuel output by the primary mixing pipeline as an example, the working requirements set by the stirring mixer can be understood as different starting blending liquid level heights and rotating nozzle speeds corresponding to different oil viscosity ranges. At this time, the working parameters are the starting blending liquid level heights and rotating nozzle speeds corresponding to the range including the oil viscosity, and are not limited to this.

[0066] Then, after determining the working parameters of the stirring mixer, the controller can control the stirring mixer to stir the primary mixed fuel output from the primary mixing pipeline according to the working parameters, thereby ensuring the stirring effect of the target blending fuel.
