[0053] Step S14: Based on the heat released, determine the target combustion stage used by the burner head; wherein, the heat released corresponds to different target combustion stages.

[0054] The variable flow temperature control method provided in this invention can be executed by a device; the device can be any device including a processing module or processing chip, etc. For example, the device can be at least one of the following: a computer or server, etc. The device can be a device in a variable flow temperature control system; for example, the device can be a device installed in the heater of the variable flow temperature control system, in which case the device can be a device or component with processing and communication capabilities, etc. The device can be a device connected to the de-icing system and the fuel system in the variable flow temperature control system.

[0055] The de-icing fluid provided in this embodiment of the invention can be any liquid that can absorb heat, such as ethylene glycol; the fuel can be any combustible liquid, such as diesel; no restrictions are placed on the de-icing fluid and / or fuel.

[0056] See Figure 2 and Figure 3 In one embodiment, the variable flow temperature control system includes: a fuel system and a de-icing system; the fuel system includes a fuel tank, a fuel pump, a fuel pressure gauge, and a burner head; the de-icing system includes a de-icing fluid tank, a de-icing pump, a flow meter, a heater, and a spray outlet. The aforementioned equipment may be connected to the fuel system and the de-icing system; or the aforementioned equipment may be a processing chip or processing module disposed in the heater.

[0057] See Figure 3 In one embodiment, the fuel in the combustion head of the fuel system atomizes fuel into fine droplets and sprays them into the combustion chamber at a predetermined diffusion angle; then the atomized fuel mixes with the air supplied to the combustion chamber and ignites; the heater of the de-icing system transfers the heat from the combustion chamber to the de-icing fluid in the de-icing fluid tank. This allows for both combustion operations of the combustion system and de-icing operations of the de-icing system.

[0058] In one embodiment, obtaining the mass of the de-icing fluid in step S11 includes: obtaining the flow rate of the de-icing fluid per unit time using a flow meter of the de-icing system; determining the volume of the de-icing fluid based on the flow rate and the flow rate per unit time; and determining the mass of the de-icing fluid based on the volume and density of the de-icing fluid.

[0059] For example, the equipment can determine the mass m1 of the de-icing fluid as follows: m1 = ρ1 × V1 = ρ1 × q1 × T1; where q1 is the flow rate of the de-icing fluid per unit time, T1 is the unit time, ρ1 is the density of the de-icing fluid, and V1 is the volume of the de-icing fluid. Optionally, the unit of measurement for the mass of the de-icing fluid is kilograms (Kg); the unit of measurement for the density of the de-icing fluid is grams per cubic meter (Kg / L); the unit of measurement for ...

[0060] Of course, in other embodiments, the unit of measurement for the density of the de-icing fluid, the unit of measurement for the unit of measurement for the unit of measurement for the flow rate of the de-icing fluid, and / or the unit of measurement for the volume of the de-icing fluid can be any feasible unit of measurement, and there is no limitation herein.

[0061] In one embodiment, obtaining the heater outlet temperature and heater inlet temperature in step S11 includes: detecting the outlet temperature of the heater outlet and the inlet temperature of the heater inlet.

[0062] In one embodiment, step S12 includes: determining a second difference based on the difference between the outlet temperature and the inlet temperature; and determining the heat absorbed by the de-icing fluid based on the product of the second difference and the mass of the de-icing fluid.

[0063] For example, the equipment determines the heat absorbed by the de-icing fluid, Q1, as follows: Q1 = C1 × m1 × (t - t0); where C1 is the specific heat capacity of the de-icing fluid, m1 is the mass of the de-icing fluid, t is the outlet temperature, t0 is the inlet temperature, and t - t0 is the second difference. Optionally, the unit of measurement for the heat absorbed by the de-icing fluid is kilojoules (kJ); the unit of measurement for the mass of the de-icing fluid is kilograms (kg); the unit of measurement for the specific heat capacity of the de-icing fluid is kilojoules per kilogram of degree Celsius (kJ / kg·°C); and the units of measurement for the outlet temperature and the inlet temperature are degrees Celsius (°C).

[0064] Of course, in other embodiments, the unit of measurement for the heat absorbed by the de-icing fluid, the unit of measurement for the mass of the de-icing fluid, the unit of measurement for the specific heat capacity of the de-icing fluid, the unit of measurement for the outlet temperature, and / or the unit of measurement for the inlet temperature can be any feasible unit of measurement, and there is no limitation herein.

[0065] In one embodiment, as shown in Table 1, a table relating the heat absorbed to a second difference is provided.

[0066]

[0067] Table 1

[0068] In one embodiment, step S13 includes: determining the exothermic heat of the fuel as the endothermic heat of the de-icing fluid. This ensures that the heat absorbed by the de-icing fluid is exactly the heat released by the fuel, maximizing combustion efficiency while maintaining effective de-icing.

[0069] In another embodiment, step S13 includes: determining that the difference between the exothermic heat of the fuel and the endothermic heat of the de-icing fluid is less than or equal to a predetermined heat value. Optionally, the predetermined heat value is less than or equal to a first heat value. Optionally, the device can obtain the exothermic heat based on the endothermic heat plus the predetermined heat value; or, the device can obtain the exothermic heat based on the endothermic heat minus the predetermined heat value. In this way, the heat absorbed by the de-icing fluid can be substantially matched with the heat released by the fuel, and both de-icing and combustion effects can be taken into account.

[0070] In another embodiment, step S13 includes determining that the exothermic heat of the fuel is less than the endothermic heat of the de-icing fluid. This can improve the de-icing effect.

[0071] In one embodiment, the device determines the exothermic heat of the fuel based on the product of the fuel's calorific value and its mass.

[0072] For example, the device can determine the exothermic heat Q2 of the fuel oil as follows: Q2 = q c ×m2= q c ×ρ²×V²= q c ×ρ²×q²×T²; where q c Let m2 be the calorific value of the fuel, ρ2 be the density of the fuel, V2 be the volume of the fuel, q2 be the flow rate of the fuel per unit time, and T2 be the unit of time. Optionally, the unit of measurement for the exothermic heat of the fuel is kilojoules (kJ); the unit of measurement for the calorific value of the fuel is kilojoules per kilogram (kJ / kg); the unit of measurement for the mass of the fuel is kilograms (kg); the unit of measurement for the density of the fuel is grams per cubic meter (kg / L); the unit of measurement for the volume of the fuel is liters (L); the unit of measurement for the flow rate of the fuel is liters per second (L / S); and the unit of measurement for the unit of time is seconds (S).

[0073] Of course, in other embodiments, the units of measurement for the exothermic heat of fuel, the calorific value of fuel, the mass of fuel, the density of fuel, the volume of fuel, the flow rate of fuel, and / or the unit of measurement per unit time can be any feasible units of measurement, and there is no limitation herein.

[0074] In this embodiment of the invention, the device can be based on Q2=q c ×m2= q c The exothermic heat function ×ρ2×V2 determines the mass or volume of the fuel; and can be based on Q2= q c The exothermic heat function ×ρ²×q²×T² determines the fuel flow rate; thus, the required fuel mass for the burner head can be determined based on this exothermic heat function, thereby further determining the number of burner heads to open and / or the spray flow rate of the burner heads. Here, the spray flow rate is the fuel flow rate. Optionally, the spray flow rate of each open burner head can be matched based on the fuel flow rate; wherein, the sum of the spray flow rates of each open burner head is the fuel flow rate.

[0075] Optionally, since different spray flow rates correspond to different spray pressures of the burner head, the embodiments of the present invention can also set the spray pressure of the burner head based on the required spray flow rate of the burner head.

[0076] like Figure 4 As shown, in some embodiments, step S14 includes:

[0077] Step S141: Based on the exothermic heat, determine the number of burners to be opened and / or the spray flow rate of the burners;

[0078] Step S142: Determine the target combustion stage used by the burner head based on the number of openings and / or the spray flow rate.

[0079] For example, the heat released by the device is distributed to the number of at least one burner head that is turned on, such that the sum of the spray flow rates of at least one burner head per unit time is the heat released.

[0080] For example, the device is pre-configured with mapping information, which indicates the correspondence between the number of burner heads opened and / or the spray flow rate of the burner heads, and the alternative combustion stages; step S142 includes: the device determining the target combustion stage used by the burner heads based on the number of burner heads opened and / or the spray flow rate, and the mapping information. The alternative combustion stage corresponding to the number of burner heads opened and / or the spray flow rate is the target combustion stage.

[0081] In one embodiment, there can be K alternative combustion stages; K is an integer greater than 0; different alternative combustion stages correspond to different numbers of burner heads opened and / or different spray flow rates.

[0082] In one embodiment, as shown in Table 2, a table relating exothermic heat and alternative combustion stages is provided; wherein, there can be 13 alternative combustion stages, for example, the 13 alternative combustion stages can be represented as stage_1 to stage_13.

[0083]

[0084] Table 2

[0085] In this embodiment of the invention, the mass of the de-icing fluid, the outlet temperature of the heater, and the inlet temperature of the heater can be obtained. Based on the mass of the de-icing fluid, the outlet temperature, and the inlet temperature, the heat absorption of the de-icing fluid is determined. Based on the heat absorption, the heat release of the fuel is determined. Based on the heat release, the target combustion stage for the burner head is determined. Different target combustion stages correspond to different heat releases. Thus, this embodiment of the invention can determine the heat release of the fuel based on the heat absorbed by the de-icing fluid, achieving automatic matching of the heat absorbed by the de-icing fluid and the heat released by the fuel. When the burner head determines the target combustion stage based on this heat release, both de-icing effect and combustion efficiency can be considered, thereby saving energy while achieving stable and reliable operation. This embodiment of the invention can achieve a better de-icing effect, i.e., it can reduce the temperature and achieve stable system temperature operation.

[0086] Furthermore, the number of burner heads to be opened and / or the spray flow rate can be determined based on the heat released by the de-icing fluid. This allows for automatic control of the burner head startup and subsequent flow rate, enabling automatic control of the combustion system to switch to the target combustion stage.

[0087] It is understandable that the flow rate (e.g., fuel flow rate or de-icing fluid flow rate) and heat (exothermic or endothermic heat) of the de-icing system exhibit strong discrete characteristics. A monitoring system can detect when the heater trigger condition is met and respond with fuel heat based on the endothermic heat corresponding to de-icing. Optionally, this monitoring system can be an in-equipment monitoring system or a monitoring system within a variable flow temperature control system. Data analysis of the endothermic heat and exothermic heat can be used to derive a corresponding variable flow temperature control method based on fuzzy algorithms. For example, see [link to example]. Figure 5 The variable flow temperature control method based on fuzzy algorithms includes the following steps: operating the de-icing system; starting the heater; heating when the heater conditions are met, and inputting the fuel quantity corresponding to fuel combustion into the fuzzification interface to generate a first fuzzy vector; inputting the first fuzzy vector into an inference engine, where the inference engine infers the first fuzzy vector based on fuzzy rules to obtain a second fuzzy vector; outputting the second fuzzy vector from the defuzzification interface; the second fuzzy vector is used to determine the heater combustion stage; inputting the difference between the heater outlet temperature and inlet temperature during the heater combustion stage into a summer, which sums the fuel quantity and the difference between the heater outlet temperature and inlet temperature. Optionally, the monitoring system also includes a database and a rule base. Optionally, the second fuzzy vector can be a target fuzzy vector; the heater combustion stage can be a target combustion stage.

[0088] For example, the fuzzification interface serves as the input interface for the fuzzy controller; it converts a true deterministic input into a fuzzy vector. The database stores the membership vector values ​​of all fuzzy subsets of all input or output variables; it provides data to the inference engine. The rule base provides fuzzy rules to the fuzzy controller. The inference engine, within the fuzzy controller, solves for fuzzy relationships based on the first fuzzy vector input and the fuzzy rules, obtaining a second fuzzy vector. The defuzzification interface serves as the output interface for the fuzzy controller; it defuzzifies the data to obtain a clear control output.

[0089] like Figure 6 As shown, in some embodiments, determining the target combustion stage for the burner head based on the exothermic heat in step S14 includes:

[0090] Step S143: Blur the first difference to generate a first fuzzy set; wherein the first difference is a preset difference between the outlet temperature and the inlet temperature;

[0091] Step S144: Fuzzify the standby combustion stage to generate a second fuzzy set;

[0092] Step S145: Input the second difference, the first fuzzy set, and the second fuzzy set into the fuzzy controller to obtain the target fuzzy vector; wherein, the second difference is the difference between the outlet temperature and the inlet temperature corresponding to the exothermic heat; the fuzzy rule of the fuzzy controller is to perform a union operation on the intersection of at least one first fuzzy set and the second fuzzy set;

[0093] Step S146: Based on the target fuzzy vector, determine the target combustion stage used by the burner head.

[0094] In one embodiment, the first difference is divided into at least one difference interval, and one difference interval corresponds to a first fuzzy set.

[0095] In this embodiment of the invention, the first difference, i.e., deviation e, and the standby fuel stage, i.e., the control quantity u, can be fuzzified to generate a first fuzzy set and a second fuzzy set of fuzzy signals. These first and second fuzzy sets are then input into a fuzzy controller, and a target fuzzy vector is obtained based on the fuzzy rules of the controller. Based on the target fuzzy vector, the target combustion stage is determined. This allows for the automatic determination of the target combustion stage used by the burner head using a fuzzy algorithm, enabling continuous adjustment, modification, and improvement of the target combustion stage, thus achieving precise control of the target combustion stage of the burner head.

[0096] Furthermore, the embodiments of the present invention achieve control of the target combustion stage of the burner head through fuzzy algorithms, which does not require numerical values ​​but uses linguistic fuzzy vectors to describe it, so that the fuzzy controller does not need to establish a complete mathematical model and can be easily implemented.

[0097] In one embodiment, step S143, which involves fuzzifying the first difference to generate a first fuzzy set, includes: dividing the first difference into N first fuzzy sets, wherein each first fuzzy set includes M difference change levels; where N and M are both integers greater than 1.

[0098] Step S144 includes: dividing the standby combustion stage into N second fuzzy sets corresponding to the first fuzzy set, wherein each second fuzzy set includes L combustion change levels; where L is an integer greater than 1.

[0099] In one embodiment, the following fuzzy rule is determined:

[0100] The greater the difference between the current heater outlet temperature and inlet temperature, the higher the fuel combustion stage.

[0101] The smaller the difference between the current heater outlet temperature and inlet temperature, the lower the fuel combustion stage.

[0102] If the current outlet temperature and inlet temperature of the heater are close, it indicates that the combustion stages of the fuel are close.

[0103] In one embodiment, the first fuzzy set can be five. For example, the device uses the difference between the heater's outlet and inlet temperatures, i.e., the first difference, as the deviation e of the observed quantity, and divides the deviation e into five first fuzzy sets: negative large (NB), negative small (NS), zero (ZO), positive small (PS), and positive large (PB); the range of variation of this deviation e can be divided into seven levels: -3, -2, -1, 0, 1, 2, and 3. For example, the first fuzzy set of this deviation e is shown in Table 3.

[0104]

[0105] Table 3

[0106] Thus, in the embodiments of the invention, the difference between the outlet temperature and the inlet temperature of the heater can be fuzzified to obtain a first fuzzy set that can be input into the fuzzy controller.

[0107] In one embodiment, the second fuzzy set can be five. For example, the device uses the alternative combustion stage as the control variable u, and divides the control variable u into five second fuzzy sets: negative large (NB), negative small (NS), zero (ZO), positive small (PS), and positive large (PB); and divides the range of variation of the control variable u into nine levels: -4, -3, -2, -1, 0, 1, 2, 3, and 4. For example, the second fuzzy set of this control variable u is shown in Table 4.

[0108]

[0109] Table 4

[0110] Thus, in the embodiments of the invention, the alternative combustion stages can be fuzzified to obtain a second fuzzy set that can be input into the fuzzy controller.

[0111] In one embodiment, the following fuzzy rules are determined: if e is negative and large, then u is negative and large; if e is negative and small, then u is negative and small; if e is 0, then u is 0; if e is positive and small, then u is positive and small; if e is positive and large, then u is positive. The above module rules can be described in the form of "if A then B": if e=NB then u=NB; if e=NS then u=NS; if e=0 then u=0; if e=PS then u=PS; if e=PB then u=PB.

[0112] For example, Table 5 provides a fuzzy control table for a first fuzzy set and a second fuzzy set; the first fuzzy set can be represented by NBe, NSe, Zoe, PSe and PBe; the second fuzzy set can be represented by NBu, NSu, Zou, PSu and PBu.

[0113]

[0114] Table 5

[0115] Thus, by associating the first and second fuzzy sets through fuzzy rules, it is possible to prepare a characterization of the relationship between the difference between the outlet and inlet temperatures and the alternative combustion stages.

[0116] In some embodiments, step S145, which involves inputting the second difference, the first fuzzy set, and the second fuzzy set into the fuzzy controller to obtain the target fuzzy vector, includes:

[0117] Find the intersection of the first to Nth first fuzzy sets with the first to Nth second fuzzy sets respectively to obtain the first to Nth fuzzy intersections;

[0118] The union of the first to Nth fuzzy intersections is obtained by taking the union of the fuzzy unions.

[0119] The target fuzzy vector is determined based on the second difference and the fuzzy union, wherein the second difference corresponds to M levels of difference change.

[0120] For example, there are 5 first fuzzy sets, which can be represented by NBe, NSe, ZOe, Zoe, PSe, and PBe, respectively; and 5 second fuzzy sets, which can be represented by NBu, NSu, ZOu, PSu, and PBu, respectively. The fuzzy intersection of negative large (NB), i.e., the first fuzzy intersection, can be: The fuzzy intersection of negative small (NS), i.e., the second fuzzy intersection, can be: The fuzzy intersection of zero (ZO), i.e., the third fuzzy intersection, can be: The fuzzy intersection of positive small (PS), i.e., the 4th fuzzy intersection, can be: The fuzzy intersection of Zhengda (PB), specifically the 5th fuzzy intersection, can be: Find the union of the first to fifth fuzzy unions to obtain the fuzzy union R = The fuzzy union obtained from the above 5 fuzzy intersections is: Alternatively, fuzzy rules can be represented using functions in R.

[0121] In one embodiment, determining the target fuzzy vector based on the second difference and the fuzzy union includes: determining the target fuzzy vector based on the intersection of the second difference and the fuzzy union.

[0122] For example, if the second difference is NB, the intersection of this second difference (i.e., deviation e) and the fuzzy union yields the target fuzzy vector U, which can be: .

[0123] In this embodiment of the invention, N first fuzzy sets and N second fuzzy sets can be input into a fuzzy controller to obtain a fuzzy union, that is, to obtain the maximum value of the membership function, so as to truly reflect the relationship between the difference between the outlet temperature and the inlet temperature and the alternative combustion stage; and based on the difference between the current outlet temperature and the inlet temperature (i.e., the second difference) and the fuzzy union, a target fuzzy vector that conforms to the current combustion situation can be determined.

[0124] In some embodiments, step S146 includes: determining the target combustion stage used by the burner head based on the L combustion change levels corresponding to the target fuzzy vector and the current combustion level.
