[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figure 1 As shown, the present invention is a liquid industrial medium diversion processing control system, comprising:

[0049] A monitoring module, used for real-time monitoring of the fluid medium flow rate at each preset branch sub-tube outlet;

[0050] A distribution module, used for distributing the fluid medium flow at each preset branch sub-tube outlet according to the distribution strategy;

[0051] The data acquisition module is used to collect the real-time pressure value, real-time flow velocity, and real-time flow cross-sectional area of ​​the flow of the transmission fluid medium at the detection points in the main pipe and each sub-pipe;

[0052] The data analysis module is used to analyze the time variation information of the real-time pressure value, real-time flow velocity, and real-time flow cross-sectional area within a preset time period, and judge the uniformity of the fluid medium distribution flow at the preset flow dividing sub-tube outlet after each distribution process according to the analysis results; and adjust the distribution strategy according to the judgment results;

[0053] A flow distribution control module, used to control the flow of the fluid medium to different storage containers according to the adjusted distribution strategy;

[0054] The feedback module is used to feed back the shunt control status to the monitoring module according to the control result of the shunt control module.

[0055] In the above technical scheme, the present invention monitors the flow rate of the fluid medium flowing out of each diversion sub-pipe outlet in real time through the monitoring module, and realizes the early warning process of the diversion control status of the diversion control result feedback information by setting other modules. Specifically, during the medium diversion process, the monitoring module continuously monitors the flow data of the fluid medium and feeds it back to the distribution module of the liquid industrial medium diversion processing control system, so as to distribute and process the fluid medium flow rate of each preset diversion sub-pipe outlet according to the distribution strategy; the distribution strategy is adjusted according to the actual situation, and the diversion control module can control the fluid medium to be diverted to different storage containers according to the optimized and adjusted distribution strategy, so as to improve the efficiency and stability of the system's diversion of the sub-pipes. After the diversion process is completed, the system needs to perform a shutdown operation, including closing all valves, stopping the operation of the pump, and saving the system's operating data.

[0056] In addition to the above-mentioned monitoring module, distribution module and shunt control module, the design system of the present invention is also provided with a data acquisition module, a data analysis module and a feedback module to process the shunt-related data obtained during the monitoring process and judge the flow distribution state of the main pipe and the sub-pipe; first, the real-time pressure value, real-time flow velocity and real-time flow cross-sectional area of ​​the transmission fluid medium flow at the detection points in the main pipe and each sub-pipe are collected through the data acquisition module; the state information between the shunt pipe openings is reflected, and then the flow state of the fluid medium at the outlet of the sub-pipe is judged to realize the adjustment process of the distribution strategy; then, the data analysis module is used to analyze the time variation information of the real-time pressure value, real-time flow velocity and real-time flow cross-sectional area within a preset time period, and according to the calculation formula in the monitoring and control process, the analysis result is further judged, the flow size of the fluid medium at the outlet of each preset shunt sub-pipe after each distribution process is judged, and the distribution strategy is adjusted according to the judgment result, so as to realize the uniform shunt processing process of the shunt control module; finally, the shunt control state is fed back to the monitoring module according to the control result of the shunt control module through the feedback module, and then further shunt adjustment is made according to the shunt state result and actual needs.

[0057] Before starting the diversion process, each module process of the above system performs equipment and data initialization, including checking whether all sensors, valves and actuators are working properly, and setting the initial control parameters; it also includes detecting the flow, pressure, temperature and other parameters of the liquid industrial medium through sensors, and transmitting these data to the control system of this design.

[0058] As an implementation mode of the present invention, the allocation strategy includes:

[0059] Acquire the real-time fluid medium flow rate according to the initial nozzle allocation frequency and the initial nozzle allocation cycle;

[0060] Feedback adjustment is made to the initial nozzle allocation frequency and initial nozzle allocation period based on the distribution flow uniformity judgment result.

[0061] In the above technical scheme, the allocation strategy in this embodiment realizes the flow distribution processing setting before executing the diversion processing. The setting content includes the initial pipe mouth allocation frequency and the initial pipe mouth allocation period, and the real-time fluid medium flow data is acquired according to these two allocation conditions. The allocation strategy also makes corresponding adjustments to the initial allocation settings according to the results of the distribution flow uniformity judgment, thereby realizing the diversion control process of the diversion flow.

[0062] As an implementation mode of the present invention, the data analysis module:

[0063] By formula Calculate and obtain the allocation coefficient Par; where n is the total number of sub-tubes connected to the mother tube, and only one detection point is set at the connection between each sub-tube and the mother tube; therefore i∈[1,n]; f is the preset allocation function; μ1 is the first preset weight coefficient, μ2 is the second preset weight coefficient, and μ3 is the third preset weight coefficient; and μ1, μ2, and μ3 are all greater than 0; t1 is the start time of the preset time period, t2 is the end time of the preset time period, [t1, t2] is the preset time interval, and t2>t1>0; p i (t) is the real-time pressure value of the detection point in the i-th sub-tube, r i (t) is the real-time flow velocity of the detection point in the ith sub-tube; fl i (t) is the real-time flow cross-sectional area of ​​the detection point in the i-th sub-tube; Q ai is the first conversion function; Q si is the second conversion function; Q di is the third conversion function.

[0064] In the above technical solution, in this embodiment, the calculation process of the distribution coefficient of the data analysis module is realized through a calculation formula, and the distribution coefficient is obtained and compared with the preset standard threshold. When it belongs to the preset standard threshold interval, it can further judge the state of the fluid medium flow in each sub-tube through the mother pipe. Specifically, under normal circumstances, when the fluid medium flow is normally distributed from the mother pipe to each sub-tube, and the change state of the pressure and flow rate in each sub-tube within a preset time period is constant, the cross-sectional area change of the flow is also in a relatively stable state; therefore, the size of its distribution coefficient should be in a relatively stable state. If it exceeds or is less than this standard range, it is judged that there is a problem with the distribution of the fluid medium flow, and there may be a situation where the distribution flow of the sub-tube is too small or too large, and the flow distribution adjustment needs to be made in time. Specifically, through the formula The distribution coefficient Par is obtained by calculation, and the flow distribution state of the sub-pipe can be further reflected according to the size of the distribution coefficient obtained by calculation.

[0065] It should be explained that the preset weight coefficients μ1, μ2, and μ3 are obtained by fitting the empirical test data, which will not be described in detail here; the first conversion function Q ai , the second conversion function Q si , the third conversion function Q di The values ​​are obtained by fitting the test data of the sub-pipe in the normal flow diversion state during the diversion process of the system. Therefore, by bringing in the real-time pressure value p of the sub-pipe i (t), real-time flow rate r i (t) and real-time flow cross-sectional area fl i(t), and then transform the allocation function by obtaining the state change in the preset time period, and then obtain the distribution of the overall traffic. The preset allocation function f usually refers to the allocation rules or logic predefined in some systems or algorithms to guide the allocation process of resources, data or tasks; it is an adjustment function set according to historical data to ensure that the adjustment coefficient is within a specific reasonable range.

[0066] As an embodiment of the present invention, the data analysis module further includes:

[0067] The distribution coefficient Par is compared with the preset standard distribution coefficient threshold interval [Par A ,Par B ] for comparison:

[0068] If Par∈[Par A ,Par B ], it is judged that the flow distribution uniformity of the fluid medium flow at the outlet of the current flow splitter tube is reasonable;

[0069] like It is determined that the flow distribution uniformity of the fluid medium flow at the outlet of the current flow splitter pipe is unreasonable, the monitoring module generates an early warning signal and the distribution module adjusts the distribution strategy.

[0070] In the above technical scheme, in this embodiment, by comparing the sizes of the distribution coefficients, a comparative analysis is performed through the size of the standard distribution coefficient threshold interval pre-set according to historical experience data. If it meets the interval, it is judged that the uniformity of the distribution flow obtained after the current diversion processing meets the requirements. Otherwise, it is judged that there is a problem with the uniformity of the distribution flow, and further processing is performed: an early warning signal is generated and the distribution strategy is adjusted; so as to realize timely control of the flow of the diverted fluid medium.

[0071] As an implementation mode of the present invention, the allocation strategy is adjusted as follows:

[0072] like Further:

[0073] If Par>Par B , it is judged that the fluid medium flow rate at the outlet of the current flow splitter tube is abnormally high, so the distribution frequency is reduced and the pipe outlet distribution cycle is extended:

[0074] The frequency of pipe opening allocation after the detection point in the i-th sub-pipe is reduced: F i =F0-F0*ε1*(Par-Par B );

[0075] The pipe distribution cycle after the detection point in the i-th sub-pipe is extended:

[0076] If Par<Par A , it is judged that the fluid medium flow rate at the outlet of the current flow splitter tube is abnormally low, so the distribution frequency is increased and the pipe outlet distribution cycle is shortened:

[0077] The frequency of pipe opening allocation after the detection point in the i-th sub-pipe is improved: F i '=F0*ε2*(Par A -Par);

[0078] The pipe distribution cycle after the detection point in the i-th sub-pipe is shortened:

[0079] Among them, F0 is the initial nozzle allocation frequency, T0 is the initial nozzle allocation period; ε1 is the first frequency correction coefficient, ∈1 is the first period correction coefficient; ε2 is the second frequency correction coefficient, ∈2 is the second period correction coefficient.

[0080] In the above technical solution, the allocation strategy is adjusted in this embodiment based on the specific processing of the allocation coefficient Par. When it is greater than the maximum value Par of the preset threshold interval, B When the flow rate of the fluid medium at the outlet of the current flow splitter tube is abnormally high, it is necessary to control and reduce the flow rate of the fluid medium, that is, reduce the distribution frequency and extend the pipe distribution cycle. A When analyzing, it is found that the fluid medium flow rate at the outlet of the current flow splitter tube is abnormally low, and it is necessary to control and increase the fluid medium flow rate, that is, to increase the distribution frequency and shorten the pipe outlet distribution cycle.

[0081] ε1, ∈1, ε2 and ∈2 are all obtained after adjustment based on the rationality analysis of the risk threshold interval difference. Therefore, by executing the allocation strategy through the adjusted allocation frequency and allocation period, it is possible to achieve the effect of improving the accuracy of analysis and judgment while adaptively reducing the computing power requirements.

[0082] As an embodiment of the present invention, the system further includes:

[0083] The inlet and outlet synchronization control module is used to analyze the resistance value in the sub-pipe connected to the mother pipe and the fluid medium flow rate at the outlet of the sub-pipe based on the internal condition relationship between the mother pipe and each sub-pipe, so as to realize the synchronous adjustment of the inlet and outlet positions of the mother pipe and the sub-pipe.

[0084] In the above technical solution, an inlet and outlet synchronization control module is set to realize further logical control processing of the resistance value in the sub-pipe connected to the main pipe and the fluid medium flow at the outlet of the sub-pipe: the control system calculates the results of the diversion processing according to the preset control logic and the detected medium flow and other parameters, including which valves of the sub-pipes should be opened or closed at the same time or the opening size should be adjusted, and the valve opening size is controlled to control the direction in which the fluid medium should flow.

[0085] As an implementation mode of the present invention, the import and export synchronization control module includes:

[0086] By formula Calculate the adjustment state value Adj of the i-th sub-tube i ;

[0087] Among them, Re i is the resistance value of the ith sub-tube, Me i is the fluid medium flow rate of the ith sub-tube; Re i0 is the standard resistance value of the ith sub-tube, Me i0 is the standard fluid medium flow rate of the ith sub-tube; ΔRe i Preset resistance deviation value for the ith sub-tube, ΔMe i Preset the fluid medium flow deviation value for the i-th sub-tube; D is the distance between the main tube and the sub-tube in the internal condition, and P is the interface angle between the main tube and the sub-tube in the internal condition; is the influence function of the internal condition factors of the resistance, and ω(D, P) is the influence function of the internal condition factors of the fluid medium flow.

[0088] In the above technical solution, in this embodiment, the switching valves of the main pipe and the sub-pipe are controlled by judging the adjustment state value in the sub-pipe. This process triggers the execution control command through the comparison analysis result of the adjustment state value to control the actuator of the diversion process, such as opening or closing the main pipe or sub-pipe diversion valve, adjusting the speed of the pump, etc. Specifically, through the formula Calculate the adjustment state value Adj of the i-th sub-tube i , the regulating control conditions of the sub-pipe are obtained according to the regulating state value. The main factors causing the resistance of the sub-pipe and the flow rate of the fluid medium in the sub-pipe include the internal condition relationship between the main pipe and each sub-pipe, in addition to the digitally controllable main pipe inlet flow condition. The internal conditions include the distance relationship between the main pipe and the sub-pipe, and the interface angle relationship between the main pipe and the sub-pipe. This is the main reason affecting the final flow distribution size of each sub-pipe. Generally, the farther the distance, the longer the arrival time, and the larger the interface angle between the sub-pipe and the main pipe and the interface angle of the main pipe, the more significant the impact on the flow of the sub-pipe.

[0089] Among them, it is necessary to explain that ω(D, P) will be adjusted according to the different internal conditions of the current pipeline, and then under different internal conditions, the regulation state value will be adjusted accordingly to improve the accuracy of judgment under different internal conditions.

[0090] In the above technical solution, The relationship between ω(D, P) and the distance D between the mother tube and the daughter tube in the internal conditions and the interface angle P between the mother tube and the daughter tube in the internal conditions is obtained by selecting the average values ​​of various parameters of the daughter tube under different internal conditions, ΔRe i , ΔMe i The settings are selected based on empirical data and will not be described in detail here.

[0091] As an embodiment of the present invention, it also includes:

[0092] Adjust the state value Adj i Adjust the state threshold value Adj with the preset standard tr Compare, when Adj i Reaching the set threshold Adj tr , the flow rate of the fluid medium at the main pipe inlet and the sub-pipe outlet is synchronously controlled.

[0093] In the above technical scheme, synchronous control is performed for the situation where the set threshold is reached. The synchronous control at this time is based on the valves set in advance at the main pipe opening and the valves set at the sub-pipe connecting port opening. The process of command control is performed through the actuator according to the synchronous adjustment analysis results. Specifically, it includes issuing synchronous control instructions, selecting to control the valve opening, closing or adjusting the valve opening size, increasing or decreasing it, etc.; and for the situation where the threshold is not reached, the diversion monitoring process of the current monitoring module continues.
