[0029] Before introducing the technical solution, an exemplary description of the application scenario can be given first. The technical solution provided by the embodiments of the present invention should be applicable to any scenario where it is necessary to determine the structure of a vehicle cavity. Exemplarily, when determining the storage cavity and the perfusion cavity in a paste vehicle cavity, it is necessary to analyze the flow state of the paste in the storage cavity and the perfusion cavity to determine the specific cavity structure based on the flow state. At this time, the technical solution provided by the embodiments of the present invention can be used to analyze the flow state of the paste in the cavity. It should be noted that the storage cavity is used to receive the paste poured from the filling port of the storage cavity, stir the paste, and pour the paste into the perfusion cavity. The perfusion cavity is used to receive the paste perfused by the storage cavity, laterally push the paste, and pour the paste outwards to color various objects (such as cigarettes) with the paste.

[0030] Embodiment 1

[0031] Figure 1 FIG. is a flowchart of a method for determining a cavity structure according to Embodiment 1 of the present invention. This embodiment is applicable to the situation of determining the specific structure of the cavity of the paste vehicle. This method can be executed by a device for determining the cavity structure, and the device for determining the cavity structure can be implemented in the form of hardware and / or software. The device for determining the cavity structure can be configured in a computing device. As Figure 1 shown, the method includes:

[0032] S110. Obtain physical parameters of the paste, and determine a first paste flow state analysis model based on the physical parameters, a preset time-delay adjustment parameter, and a preset paste flow state distribution function.

[0033] Among them, the physical parameters can be parameters related to the physical properties of the paste. For example, the physical parameters include density, viscosity, dryness, fineness, fluidity, etc. The preset time-delay adjustment parameter is used to adjust the magnitude of the output state quantity of the perfusion cavity associated with the input state quantity of the storage cavity. In practical applications, the input state quantity of the storage cavity is associated with the output state quantity of the perfusion cavity. The preset paste flow state distribution function is used to characterize the state quantity corresponding to the dynamic index within the relative cavity volume of the paste in the storage cavity and the perfusion cavity at different flow times. The dynamic index can refer to an index whose properties of the paste in the cavity change as the paste flows into the cavity. For example, the dynamic index can be an index such as paste volume, paste volume capacity, or paste flow velocity. The relative cavity volume is used to characterize the relative size of the paste volume in the two cavities of the storage cavity and the perfusion cavity. The relative cavity volume can be expressed as a ratio, that is, the ratio of the paste volume in the storage cavity to the paste volume in the perfusion cavity. The state quantity can be used to describe the specific data of the dynamic index within the relative cavity volume. For example, when the dynamic index is the paste volume and its state quantity is 1, it can indicate that both the storage cavity and the perfusion cavity are filled with paste, that is, the paste volumes in the two cavities are equal and reach the maximum value; when its state quantity is greater than 0 and less than 1, it can indicate that the paste volume in the storage cavity is less than the paste volume in the perfusion cavity; when its state quantity is greater than 0, it can indicate that the paste volumes in both the storage cavity and the perfusion cavity are 0, that is, there is no paste in the storage cavity. The preset paste flow state distribution function can be a CDF (Cumulative Distribution Function).

[0034] In this embodiment, the calculation formula of the preset paste flow state distribution function CDF can be expressed as: where t represents the cumulative time component; H represents the constraint factor; v represents the relative cavity volume; I vRepresents the input state quantity of the storage cavity under dynamic indicators; O v Represents the output state quantity of the perfusion cavity under dynamic indicators; H(I v ) Represents the constraint quantity for constraining the input state quantity of the storage cavity, that is, the input state constraint quantity; H(O v ) Represents the constraint quantity for constraining the output state quantity of the perfusion cavity, that is, the output state constraint quantity. The operation result p(v) of the preset paste flow state distribution function is the state quantity corresponding to the dynamic indicators within the relative cavity volume.

[0035] Among them, sgn represents the step function, sat represents the saturation function, and k represents the preset time-delay coefficient. d represents the difference, which is used to describe I v and O v The change relationship between the two state quantities after being constrained. It should be noted that due to the lag of the air motor speed, there will be a time delay when generating the input state quantity and the output state quantity, and the degree of this time delay is represented by the time-delay coefficient k; I0 represents the initial value of the input state quantity of the storage cavity; O0 represents the initial value of the output state quantity of the perfusion cavity. I k Represents the time-delay quantity of the storage cavity; O k Represents the time-delay quantity of the perfusion cavity; The time-delay quantity can represent the paste state quantity corresponding to the dynamic indicators generated within the time-delay section. x(v), y(v) and z(v) respectively represent the three dimensions of the state quantity; I x(v) 、I y(v) and I z(v) respectively represent the state quantities of the three dimensions of the input state quantity; O x(v) 、O y(v) and O z(v) respectively represent the state quantities corresponding to the three dimensions of the output state quantity. The correlation relationship between the input state quantity and the output state quantity can be expressed as:

[0036] ω(k) is called the time-delay disturbance coefficient.

[0037] It should be noted that when there is a time delay, when k = 0, ω(0) = 0, and at this time, the correlation relationship between the input state quantity and the output state quantity can be converted to:

[0038] I x(v) =O x(v) ·|I0|

[0039] I y(v) =O y(v) ·|I0|

[0040] I z( v ) =O z( v) ·|I0|;

[0041] Since the initial constraint amount is zero, i.e., I0 = 0, substituting I0 = 0 into the correlation relationship between the input state quantity and the output state quantity, we can obtain: I v = 0; O v = 0; I x(v) = 0; I y(v) = 0; I z(v) = 0. It can be seen from this that the state quantity p(v) corresponding to the dynamic index within the relative cavity volume is 0, that is In this case, it will cause the preset paste flow state distribution function not to form a cumulative distribution, thus affecting the actual working effect of the cavity.

[0042] To solve this problem, and also considering that the physical indicators of the paste will have a certain impact on the paste flow state. The physical parameters of the paste can be determined according to the type of the paste, and the physical parameters are applied to the preset paste flow state distribution function. At the same time, the preset time-delay adjustment parameter is used to adjust the correlation relationship between the input state quantity and the output state quantity in the preset paste flow state distribution function. Taking the adjusted preset paste flow state distribution function as the first paste flow state analysis model can effectively avoid the situation where the input and output state quantities are 0 when there is a time delay, and at the same time enable the state quantity of the dynamic index to be determined by combining the physical parameters and the preset paste flow state distribution function, improving the accuracy of determining the paste state quantity.

[0043] In this embodiment, based on the physical parameters, the preset time-delay adjustment parameter, and the preset paste flow state distribution function, the first paste flow state analysis model is determined, including: adjusting the preset paste flow state distribution function based on the physical parameters to obtain the fourth paste flow state analysis model; adjusting the correlation relationship between the input state quantity of the paste in the storage cavity and the output state quantity in the perfusion cavity in the fourth paste flow state analysis model based on the preset time-delay adjustment parameter; determining the first paste flow state analysis model based on the adjusted fourth paste flow state analysis model.

[0044] In practical applications, the physical parameters and the preset paste flow state distribution function can be integrated to obtain the fourth paste flow state analysis model. Optionally, the physical parameters can be the paste fineness and the paste fluidity, and the expression of the fourth paste flow state analysis model can be expressed as: Among them, the fineness c of the ink paste and the fluidity e of the ink paste are used as two controlled objects; G(c, e) represents the influence weight of the fineness c of the ink paste and the fluidity e of the ink paste on the determined state quantity. Further, a preset time-delay adjustment parameter can be introduced into the fourth ink paste flow state analysis model to adjust the correlation between the input state quantity of the ink paste in the storage cavity and the output state quantity in the perfusion cavity in the fourth ink paste flow state analysis model. For example, the adjusted correlation in the fourth ink paste flow state analysis model can be expressed as:

[0045] L represents the preset time-delay adjustment parameter, and ∨ represents the OR operation (i.e., logical operation. If at least one of the two values is true (1), the output is true (1); if both input values are false (0), the output is false (0)). When there is a time delay and k = 0, assuming L is set to 1 and the OR operation is performed using L, it can be known that: I v = 1; O v = 1; I x(v) = 1; I y(v) = 1; I z(v) = 1. Thus, it avoids the problem that the starting quantity (I0) at the input end is zero in the state quantities (I x(v) , I y(v) and I z(v) ) in the three dimensions of the relative cavity volume v due to the time delay k = 0, and thus avoids the problem that the cumulative distribution cannot be formed. As shown in Figure 2 , Figure 2 the darker area in is the cumulative distribution diagram of the ink paste state quantity when a preset time-delay adjustment parameter L is introduced.

[0046] Optionally, based on the adjusted fourth ink paste flow state analysis model, determining the first ink paste flow state analysis model includes: determining a preset time-delay constraint condition; constraining the preset time-delay adjustment parameter in the adjusted fourth ink paste flow state analysis model based on the preset time-delay constraint condition to obtain the first ink paste flow state analysis model. Among them, the preset time-delay constraint condition is used to constrain the preset time-delay adjustment parameter in the adjusted fourth ink paste flow state analysis model.

[0047] It should be noted that introducing a preset time-delay adjustment parameter L equal to 1 can indeed avoid the problem that the state quantities (I x(v) , I y(v) and I z(v) ) in the three dimensions of the relative cavity volume v are zero, but it means that the cavity is in a saturated state, and its input and output state quantities reach the limit or maximum working load. When the cavity (storage cavity and perfusion cavity) is in a saturated state, the ink paste will accumulate in large quantities at the output end of the cavity, causing problems such as ink paste blockage or poor output. In the cumulative distribution diagram, it is reflected as Ov The output end region will exceed the critical line, as Figure 3 shown. This obviously cannot meet the actual working requirements of the paste vehicle. Therefore, to solve this problem, a preset time delay constraint condition can be set to constrain the preset time delay adjustment parameter. The way to determine the preset time delay constraint condition can be: determine the preset time delay parameter, and based on the time delay amount generated by the paste in the cavity under the preset time delay parameter, determine the saturation coefficient; when the saturation coefficient meets the first condition, constrain the preset time delay adjustment parameter to the first threshold; when the saturation coefficient meets the second condition, constrain the preset time delay adjustment parameter to a value different from the first threshold. Among them, both the first condition and the second condition are related to the time delay amount. The preset time delay parameter is used to represent the time delay size when the paste generates the input state quantity and the output state quantity in the cavity. For example, the larger the preset time delay parameter, the longer the time delay; the smaller the preset time delay parameter, the shorter the time delay; when the preset time delay parameter is 0, it means there is no time delay, that is, no time lag. The time delay amounts generated by the paste in the cavity under different preset time delay parameters are different. For example, the larger the preset time delay parameter, the more the time delay amount; the smaller the preset time delay parameter, the less the time delay amount; when the preset time delay parameter is 0, the time delay amount is 0. The first threshold can be 1.

[0048] Specifically, the saturation coefficient corresponding to the preset time delay parameter can be determined according to the time delay amount generated by the paste in the cavity under different preset time delay parameters. The preset time delay constraint condition can be: when the saturation coefficient meets the first condition, constrain the preset time delay adjustment parameter to the first threshold; when the saturation coefficient meets the second condition, constrain the preset time delay adjustment parameter to a value other than the first threshold. That is to say, the saturation coefficient value and the preset time delay adjustment parameter can be associated, and the preset time delay adjustment parameter can be constrained by the saturation coefficient value to avoid the cavity being in a saturated state. For example, the first condition can be that the saturation coefficient approaches a negative number. When the saturation coefficient approaches a negative number, it means that the cavity is about to be in a time delay state. At this time, the preset time delay adjustment parameter is constrained to 1; the second condition can be that the saturation coefficient approaches a positive number. When the saturation coefficient approaches a positive number, it means that the cavity is about to be in a non-time delay state, and the preset time delay adjustment parameter is constrained to a non-1 value. Further, based on the preset time delay constraint condition, the size of the preset time delay adjustment parameter in the adjusted fourth paste flow state analysis model can be constrained, and the constrained fourth paste flow state analysis model is used as the first paste flow state analysis model.

[0049] Exemplarily, the preset time delay constraint condition can be expressed as: where u represents the saturation coefficient; means that when the time delay coefficient k approaches positive infinity, The limit value; -∞ represents negative infinity; +∞ represents positive infinity; → represents approaching; L represents a preset time-delay adjustment parameter. Correspondingly, the calculation method of the first paste flow state analysis model can be expressed as where |u represents the disjunctive saturation coefficient u. In practical applications, the saturation coefficient u can be calculated first. When the saturation coefficient tends to a positive number, it means that the time delay of the storage cavity exceeds that of the perfusion cavity, that is, the input state quantity of the cavity paste is greater than the output state quantity. Then, after the state quantity p(v) is disjunctively saturated by the coefficient u, it is predicted that the cavity is about to enter a non-time-delay state. At this time, in order to avoid the state quantity p(v)=1, that is, the cavity is in a saturated state, the preset time-delay adjustment parameter L can be set to a non-1 value. If u tends to a negative number, it means that the time delay of the storage cavity does not exceed that of the perfusion cavity. At this time, the input state quantity of the cavity is less than the output state quantity. After the state quantity p(v) is disjunctively saturated by the coefficient u, it is predicted that the cavity is about to enter a time-delay state. At this time, in order to avoid time delay, the preset time-delay adjustment parameter L is set to 1.

[0050] In the technical solution provided by the embodiments of the present invention, by introducing a preset time-delay constraint condition into the model, the state quantities of the paste input and output in the two cavities will not exhibit a phenomenon of no time delay or saturation within the cumulative time under the condition of applying the constraint condition.

[0051] S120. According to the pre-determined state quantity transfer function, the first paste flow state analysis model is processed respectively to obtain the second paste flow state analysis model corresponding to the storage cavity and the third paste flow state analysis model corresponding to the perfusion cavity.

[0052] It should be noted that from the adjusted correlation it can be seen that and H(O v ) = H(O x(v) .O y(v) .O z(v) )(2). Formulas (1) and (2) can be substituted into the first paste flow state analysis model . At this time, the first paste flow state analysis model is transformed into formula (3), and formula (3) is expressed as:

[0053] In formula (3), it is assumed that when t→+∞, the input end state of the paste in the cavity always maintains a cumulative distribution). k→0 means that the paste in the cavity does not generate a delay time in response to the input end state. I k→0 indicates that the paste in the storage cavity does not generate a delay time in response to the input terminal state. Formula (3) can be transformed into Formula (4), and Formula (4) is expressed as:

[0054] If L equals 1, then p(v) = 1, and p(v) = 1 indicates that the cavity is in a saturated state, and the input and output state variables reach the limit or maximum working load, which obviously does not meet the expectations.

[0055] To solve this problem, a pre-determined state variable transfer function can be used to process the first paste flow state analysis model respectively, and the second paste flow state analysis model corresponding to the storage cavity and the third paste flow state analysis model corresponding to the perfusion cavity are obtained. The specific method can be: establish a state variable transfer function described by the paste vehicle cavity, and the state variable transfer function can be expressed as: Where G s represents the state variable transfer function, s is the complex frequency parameter in the Laplace transform, O s represents the transfer change amount of the output state variable O v of the perfusion cavity, I s is the transfer change amount of the input state variable I v of the storage cavity; further, a time-delay coefficient k is introduced into the state variable transfer function, I s =(sgn(I v )·e Δθ )·k; O s =(sat(O v )·e Δθ )·k; where Δθ represents the time-delay response change amount, e represents the natural constant, approximately equal to 2.72, and the time-delay coefficient k is extracted to obtain The time-delay coefficient and can be respectively substituted into the first paste flow state analysis model (Formula (3)) to obtain the second paste flow state analysis model corresponding to the storage cavity and the third paste flow state analysis model corresponding to the perfusion cavity.

[0056] Among them, the calculation formula of the second paste flow state analysis model can be expressed as:

[0057]

[0058] The calculation formula of the third paste flow state analysis model can be expressed as:

[0059]

[0060] According to the second paste flow state analysis model and the third paste flow state analysis model, when the preset \(t\rightarrow+\infty\), \(k\rightarrow0\), \(I\) k \(\rightarrow0\). At this time, the calculation formula of the second paste flow state analysis model is expressed as:

[0061]

[0062] The calculation formula of the third paste flow state analysis model is expressed as:

[0063]

[0064] If the preset time-delay adjustment coefficient \(L = 1\), whether the result of \(p(v)\) is equal to 1 ultimately depends on \(I\) s and \(I\) v both values or \(O\) s and \(O\) v both values, which can avoid the problem of the cavity being in a saturated state.

[0065] Furthermore, according to the physical parameters of the paste, the paste cavity state quantity corresponding to the paste can be determined from a preset range; based on the paste cavity state quantity and the pre-determined state quantity transfer function, the preset time-delay parameter can be determined. Among them, the paste cavity state quantity can include at least one of the input state quantity of the paste in the storage cavity, the output state quantity of the paste in the perfusion cavity, the transfer change quantity of the output state quantity of the perfusion cavity, and the transfer change quantity of the input state quantity of the storage cavity.

[0066] It can be understood that according to the physical parameters of the paste (such as viscosity, temperature, etc.), the paste cavity state quantity corresponding to the paste can be dynamically determined from a preset range, so that by adjusting the values of the two, the state quantity of the paste in the cavity can be controlled, avoiding the problem of paste accumulation or insufficient supply caused by time delay. Furthermore, the paste cavity state quantity can be input into the pre-determined state quantity transfer function to obtain the preset time-delay parameter \(k\). After extracting the preset time-delay parameter \(k\), the determination of the state quantity \(p(v)\) of the relative cavity volume is directly transformed into the determination of the state quantities of the two cavities and their corresponding transfer change quantities.

[0067] It should be noted that the second paste flow state analysis model and the third paste flow state analysis model are not only used to respectively describe the dynamic state quantities of the paste in the storage cavity and the perfusion cavity, but also can be used to constrain the cumulative effect of the paste in the cavity after a period of time. In this way, by analyzing the long-term accumulation effect of the paste in the cavity, possible blockage problems can be avoided as much as possible, so that the design of the paste vehicle cavity can be adjusted, the paste flow path can be optimized, and the formation of flow dead zones and eddies can be reduced.

[0068] For the convenience of calculation, A and B can also be used to replace the relevant expressions in the second paste flow state analysis model and the second paste flow state analysis model formula, that is:

[0069]

[0070] Then:

[0071]

[0072] Then, set a relay limit value λ(t) of the cumulative time component t in formula (5), that is: Simplify formula (5) to formula (6), and formula (6) can be expressed as:

[0073]

[0074] Finally, the relay limit value λ(t) can be constrained, and this value can be customized. This value represents the allowed longest cumulative time, which is used to constrain the cumulative effect of the paste in the cavity corresponding to the time. For example, after setting the value of λ(t) in formula (6), using the value of λ(t) as the constraint value, screening A1 and A2 or B1 and B2 for corresponding calculations, and then analyzing the flow state of the paste in the cavity based on the calculation results. The cumulative distribution diagram of the paste cavity state is as Figure 4 shown.

[0075] S130. Based on the second paste flow state analysis model and the third paste flow state analysis model, determine the structural attributes of the paste vehicle cavity corresponding to the paste, so as to construct the paste vehicle cavity based on the structural attributes.

[0076] Among them, the structural attributes can refer to the information related to the structure of the paste vehicle cavity. For example, the structural attributes include but are not limited to volume, size, material, geometric shape of the cavity, positions of the ink inlet and outlet, etc. The paste vehicle cavity includes a target storage cavity and a target perfusion cavity.

[0077] In this embodiment, the second paste flow state analysis model can be run to analyze the flow state of the paste in the storage cavity, and the third paste flow state analysis model can be run to analyze the flow state of the paste in the perfusion cavity. According to the flow states of the paste in the storage cavity and the perfusion cavity, analyze the long-term accumulation process of the paste in the cavity, and analyze its influence on the cavity structure and flow path, so as to determine the structural attributes of the paste vehicle cavity corresponding to the paste. For example, the position of the flow dead zone can be identified by simulating the flow path of the paste in the cavity. The flow dead zone refers to the area where the paste stays stationary in the cavity, which is likely to cause long-term accumulation and blockage of the paste, and optimize the cavity structural attributes to reduce these dead zones.

[0079] Embodiment 2

[0080] As an optional embodiment of the above embodiment, in order to make those skilled in the art further understand the technical solution of the embodiments of the present invention, a specific application scenario example is given. Specifically, the following specific content can be referred to.

[0081] In this embodiment, the ink paste vehicle cavity structure can be determined based on the technical solution provided by this embodiment. The ink paste vehicle cavity structure can include a power assembly, a storage cavity, a perfusion cavity, and an air distributor. The external air source first enters the air distributor, and the air distributor outputs compressed air to the power assembly as needed. Then, the power assembly provides the power sources for the storage cavity and the perfusion cavity respectively. Finally, the storage cavity provides the storage and blending of the ink paste, and the perfusion cavity provides the perfusion of the ink paste.

[0082] The specific method can be as follows: Determine the preset paste flow state distribution function; when there is a time delay, approximate the preset time delay adjustment parameter to 1, and establish the first paste flow state analysis model to avoid the problem of inability to form a cumulative distribution. Specifically, based on physical parameters, adjust the preset paste flow state distribution function to obtain the fourth paste flow state analysis model; based on the preset time delay adjustment parameter, adjust the correlation between the input state quantity of the paste in the storage cavity and the output state quantity in the perfusion cavity in the fourth paste flow state analysis model. Based on the preset time delay constraint condition, constrain the preset time delay adjustment parameter in the adjusted fourth paste flow state analysis model to obtain the first paste flow state analysis model. The preset time delay constraint condition is: when the saturation coefficient tends to be a positive number, it indicates that the time delay of the storage cavity exceeds that of the perfusion cavity. At this time, the input quantity of the cavity is greater than the output quantity (the paste state quantity p(v) anticipates that the cavity is about to enter the non-time delay state after extracting the saturation coefficient value). To avoid the cavity being in a saturated state, set the preset time delay adjustment parameter to a non-1 value; if the saturation coefficient tends to be a negative number, it indicates that the time delay of the storage cavity does not exceed that of the perfusion cavity. At this time, the input quantity of the cavity is less than the output quantity (the paste state quantity p(v) anticipates that the cavity is about to enter the time delay state after extracting the saturation coefficient). To avoid time delay, set the preset time delay adjustment parameter to 1. Further, establish the state quantity transfer function described by the paste vehicle cavity; introduce the time delay coefficient into the transfer function; after extracting the time delay coefficient, directly convert the judgment of the state quantity in the cavity into the value result of the input state or output state and the corresponding transfer change quantity, to obtain the second paste flow state analysis model corresponding to the storage cavity of the paste and the third paste flow state analysis model corresponding to the perfusion cavity. Based on the second paste flow state analysis model and the third paste flow state analysis model, determine the structural attributes of the paste vehicle cavity corresponding to the paste, and construct the paste vehicle cavity based on the structural attributes.

[0083] The technical solution of this embodiment adopts the method of designing the cavity with single input and single output, making the cavity more concise in structure, which helps to reduce the complexity of the system and potential operation errors, thereby providing more precise control. The single input and output path can ensure the efficiency and stability of the control process. It enables the process of controlling the input and output of the paste to be synchronized or asynchronous, realizing the flexibility of control and facilitating the selection of the most suitable control method according to actual production requirements and conditions. At the same time, by reasonably combining symmetric and asymmetric process control, it can more effectively cope with the uncertainties and variations in the production process, thereby improving the robustness and reliability of the system. Thus, it can effectively improve the production efficiency and product quality of the paste vehicle cavity, while reducing operation complexity and costs.
