Description

Technical Field

[0001] The invention belongs to the technical field of centrifuge factory automatic control, and in particular relates to an automatic control method and control system for inspection parameters. Background Art

[0002] The main products of the centrifugal factory are in a vacuum pipeline during the production process, including feeding, separation, and collection. The whole process is in a sealed pipeline, and the product situation can only be mastered by monitoring the pipeline pressure, temperature, and container weight. In order to ensure that the product is under control, the parameter verification is carried out by sending samples so that the scheme can be adjusted in time. The whole process includes partial parameter acquisition, sample analysis, theoretical calculation, estimated control value, etc. Since it is impossible to directly grasp the operating status of the product in the pipeline in real time, data analysis is carried out by increasing the frequency of sample delivery. Each sample delivery requires data production, calculation, analysis, and parameter adjustment. At present, most offline factories use manual methods to record parameters, calculate manually, and analyze, and control parameters after giving adjustment values. This method not only requires a lot of manual operation, but also has the risk of untimely parameter adjustment and calculation errors, which ultimately affects product quality. Summary of the invention

[0003] The technical problem solved by the present invention is: to provide an automatic control method and control system for inspection parameters, convert real-time monitoring data into historical data, map parameters with a specific historical module, and at the same time, by processing the converted data, finally generate control adjustment parameters to control product quality.

[0004] The technical solution adopted by the present invention is:

[0005] A method for automatic control of inspection parameters includes the following steps: step 1, collecting real-time monitoring parameters, setting a data processing module to process the real-time monitoring parameters; step 2, setting a historical data module, converting the data processed by the data processing module into historical data; step 3, data monitoring presentation, cyclic mapping presentation in a data coverage manner; step 4, setting a parameter calculation module, parameter calculation; step 5, setting a parameter automatic adjustment module, modular automatic parameter adjustment.

[0006] The data processing module is provided with an input pin and an output pin, wherein the input pin is connected to the real-time monitoring parameter and the trigger button, and the output pin is connected to the converted monitoring parameter.

[0007] The input pin is connected to the real-time pressure and the inspection parameter, and the inspection parameter is not equal to the last inspection parameter as the data detection threshold. When the inspection parameter jumps once, the trigger module reads the real-time pressure and the inspection parameter once; when the inspection parameter jumps once, the data processing module performs data processing inside.

[0008] In step 2, a data detection threshold is set. When the threshold is reached, the data processing module is enabled, real-time parameters are introduced through the input pin, data is temporarily stored in the module, and finally mapped to the historical data module through the output pin.

[0009] The data processing module obtains the pressure, inspection parameters, and system time through the real-time channel, and processes them into first-time and non-first-time processing, specifically including the following steps:

[0010] A counting button Q is set. When the data processing module performs a data processing, the counting variable Q is first used to identify the number of times. When Q=1, it represents the first processing, and when Q≠1, it represents not the first processing.

[0011] Two data processing lines are set inside the data processing module, corresponding to the first data when Q=1 and the non-first data when Q≠1 respectively;

[0012] For the non-first data processing when Q≠1, a two-dimensional array X[8,13] is set in the module. When the counting variable Q≠1, the current latest pressure, inspection parameters, and system time are read through the input pin;

[0013] Use the read parameters to calculate the remaining required parameters and store them in the module variable X[Q,13];

[0014] Set Y[8,13] real-time variable modules outside the data processing module to store monitoring parameters. After each Q jump inside the data processing module, after calculating the X[Q,13] parameter, assign the internal parameter value of the module to the external real-time variable Y[Q,13] in a bit number mapping manner;

[0015] When mapping the internal X[Q, 13] of the data processing module and the external Y[Q, 13] of the module, an internal timer is used to limit the mapping function only within a specific time period to ensure the performance between the real-time parameters and the temporary storage parameters.

[0016] In step 3,

[0017] Set an array variable Y[1,13] to store the parameters produced after the first inspection parameters are obtained;

[0018] Set up four array variables Y[2,13], Y[3,13], Y[4,13], and Y[5,13] to store the parameters produced after the inspection parameters are obtained for the second to fifth times;

[0019] Take Q as the counting variable and set a loop flag variable QD_U. Every time Q exceeds 1 time, the loop variable increases by 1 and the Q count jumps to 2.

[0020] In step 4, the counting variable Q is used to identify the number of times, and by comparing the current pressure, historical pressure, current inspection parameters, and historical inspection parameters, it is determined whether the current Q data belongs to regular calculation or special calculation.

[0021] When it is determined that the current Q belongs to conventional calculation, the remaining relevant parameters are calculated using time, pressure, and inspection parameters, and mapped to the monitoring screen display;

[0022] When it is determined that the current Q belongs to a special calculation, the parameter waiting pin is set. When it is determined that the current parameter is missing, the data output through the waiting pin needs to wait for the demand. This signal is a long holding signal, and the parameter column of the current monitoring screen is temporarily vacant;

[0023] When the next inspection parameter changes and Q increases by 1, the parameter waiting pin status is detected, and the parameter is immediately returned to the waiting column for parameter completion, and the parameters in the previous column are calculated; all the parameters for this time are calculated, and the two parameters are mapped to the monitoring screen respectively.

[0024] In the step 5, the control module is set with the lowest priority, and the control module is triggered by reading the over-limit flag in the parameter calculation module; when the parameter calculation module calculates the parameter and makes a judgment on whether it is over-limit, the over-limit flag is output to the control module through the pin; after the control module reads the over-limit flag, the module is enabled and communicates with the parameter calculation module to read the specific control value; parameter control intervention is performed with the read control value, and before the intervention, the intervention condition is judged; when it is detected that the intervention object is currently in an idle state and there is an over-limit flag, a temporary control instruction can be output to adjust the controlled parameter; when the parameter reaches the predetermined target allowable error range, the over-limit flag disappears and the intervention process is interrupted.

[0025] An automatic control system for inspection parameters, comprising:

[0026] Data acquisition module, collecting real-time monitoring parameters;

[0027] The data processing module processes the real-time monitoring parameters;

[0028] The historical data module converts the data processed by the data processing module into historical data;

[0029] The data monitoring and presentation module performs cyclic mapping and presentation in the form of data coverage;

[0030] Parameter calculation module, parameter calculation;

[0031] Automatic parameter adjustment module, modular automatic parameter adjustment.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] (1) The present invention provides an automatic control method and control system for inspection parameters, which sets a data processing module and a historical data module. The difference from directly reading conventional data is that a data detection threshold is set. When the threshold is reached, the data processing module is enabled, and real-time parameters are introduced through the input pin. The data is temporarily stored in the module and finally mapped to the historical data module through the output pin.

[0034] (2) The present invention provides an automatic control method and control system for inspection parameters, which sets two data processing lines, corresponding to the first data processing and non-first data processing respectively.

[0035] (3) The automatic control method and control system of the inspection parameters provided by the present invention can realize the cycle of the counting variable Q between 2 and 5, associate Q with the array variable Y[Q,13], and perform corresponding data mapping and time capture. In this way, data presentation can be realized through an infinite cycle of a small number of variables.

[0036] (4) The present invention provides an automatic control method and control system for inspection parameters, which sets a parameter waiting pin. When it is determined that the current parameter is missing, the waiting pin outputs data to indicate the waiting requirement. The signal is a long holding signal, and the parameter column of the current monitoring screen is temporarily vacant. When the next inspection parameter changes and Q increases by 1, the parameter waiting pin state is detected, and the parameter is immediately returned to the waiting column for parameter completion, and the 10 parameters in the previous column are calculated to solve the time-delayed waiting parameter problem.

[0037] (5) The present invention provides an automatic control method and control system for inspection parameters. After the control module reads the over-limit mark, the module is enabled and communicates with the parameter calculation module to read the specific control value. The parameter control intervention is performed with the read control value. Before the intervention, the intervention condition is judged. When it is detected that the intervention object is currently in an idle state and there is an over-limit mark, a temporary control instruction can be output to adjust the controlled parameter. When the parameter reaches the predetermined target allowable error range, the over-limit mark disappears and the intervention process is interrupted. In particular, when the system automatically adjusts when the module participates in the intervention, the intervention authority is immediately released. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] 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.

[0044] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] like Figure 1As shown, the present invention provides an automatic control method for inspection parameters, which converts real-time monitoring parameters into historical temporary data, sets a cyclic overwriting method, and stores historical parameters. The parameter calculation method is set, which is divided into the first time and the non-first time, and the monitoring parameters are used to complete the remaining calculation parameters. When the first time is the first time, the signal is sent to wait, and the first time parameter is completed when the second parameter appears. The real-time parameters are converted into historical parameters by the above method, and processed, and the results are stored in the data processing module as historical parameters. However, when the parameters are judged to be over-limit, the control parameters need to be adjusted accordingly. The parameter automatic adjustment module is an intervention behavior of the system after the parameter calculation exceeds the limit. The control module is set with the lowest priority, and the control module is triggered by reading the over-limit flag in the parameter calculation module. The parameter control intervention is performed with the read control value, and the intervention condition is judged before the intervention. When it is detected that the intervention object is currently in an idle state and there is an over-limit flag, a temporary control instruction can be output to adjust the controlled parameter.

[0047] The specific steps include:

[0048] Step 1: Collect real-time monitoring parameters and set up data processing modules to process the real-time monitoring parameters

[0049] The data processing module is provided with an input pin and an output pin, wherein the input pin is connected to the real-time monitoring parameter and the trigger button, and the output pin is connected to the converted monitoring parameter.

[0050] Furthermore, the input pin is connected to the real-time pressure and the inspection parameter. The inspection parameter is not equal to the last inspection parameter as the data detection threshold, and when the inspection parameter jumps once, the trigger module reads the real-time pressure and the inspection parameter once.

[0051] Furthermore, when the inspection parameter changes once, the data processing module performs data processing inside.

[0052] Step 2: Set up a historical data module to convert the data processed by the data processing module into historical data;

[0053] As shown in Figure 2, the data processing module obtains the pressure, inspection parameters, and system time through the real-time channel, and processes them into first-time and non-first-time distinctions, specifically including the following steps:

[0054] A counting button Q is set. When the data processing module performs a data processing, the counting variable Q is first used to identify the number of times of use. When Q=1, it represents the first processing, and when Q≠1, it represents not the first time.

[0055] The data processing module has two data processing lines set inside, corresponding to the first data when Q=1 and the non-first data when Q≠1. Figure 3 shown.

[0056] For the non-initial data processing when Q≠1, a 2D array X[8,13] is set in the module. When the counting variable Q≠1, the current latest pressure, inspection parameters, and system time are read through the input pin.

[0057] Use the read parameters to calculate the remaining required parameters and store them in the module variable X[Q,13].

[0058] Set Y[8,13] real-time variable modules outside the data processing module to store monitoring parameters. After each Q jump inside the data processing module, after calculating the X[Q,13] parameter, assign the internal parameter value of the module to the external real-time variable Y[Q,13] in a bit number mapping manner.

[0059] When mapping the internal X[Q, 13] of the data processing module and the external Y[Q, 13] of the module, an internal timer is used to limit the mapping function only within a specific time period to ensure the performance between the real-time parameters and the temporary storage parameters.

[0060] Set the data processing module and the historical data module, set the data detection threshold, and when the threshold is reached, enable the data processing module, introduce real-time parameters through the input pin, process the data through temporary storage inside the module, and finally map it to the historical data module through the output pin.

[0061] Step 3: Data monitoring and presentation, cyclic mapping and presentation in the form of data coverage;

[0062] Set an array variable Y[1,13] to store the parameters produced after the first inspection parameters are obtained;

[0063] Set up four array variables Y[2,13], Y[3,13], Y[4,13], and Y[5,13] to store the production parameters after obtaining the inspection parameters for the 2nd to 5th time.

[0064] With Q as the counting variable, set a loop flag variable QD_U. When Q exceeds 1 time, the loop variable increases by 1 and the Q count jumps to 2. Figure 3 shown.

[0065] In this way, the counting variable Q can be cycled between 2-5, Q can be associated with the array variable Y[Q,13], and the corresponding data mapping and time capture can be performed. In this way, data presentation can be realized through an infinite loop of a small number of variables.

[0066] Step 4: Set the parameter calculation module and calculate the parameters;

[0067] The counting variable Q is used to identify the number of times. By comparing the current pressure, historical pressure, current inspection parameters, and historical inspection parameters, it is determined whether the current Q data belongs to regular calculation or special calculation.

[0068] When it is determined that the current Q belongs to conventional calculation, the remaining related parameters are calculated using time, pressure, and inspection parameters, and mapped to the monitoring screen display.

[0069] When it is determined that the current Q belongs to a special calculation, it is generally impossible to obtain the required time, pressure, and inspection parameters at the same time, so the remaining related parameters cannot be calculated directly. Therefore, a parameter waiting pin is set. When it is determined that the current parameter is missing, the data output through the waiting pin needs to wait for the demand. This signal is a long hold signal, and the parameter column of the current monitoring screen is temporarily vacant. When the next inspection parameter changes, and Q increases by 1, the parameter waiting pin status is detected, and the parameters of this time are immediately returned to the waiting column for parameter completion, and the parameters in the previous column are supplemented and calculated. At the same time, all the parameters for this time are calculated, and the two parameters are mapped to the monitoring screen respectively. If Figure 4 shown.

[0070] Step 5: Set up the parameter automatic adjustment module and modularize automatic parameter adjustment

[0071] The ultimate goal of automatic control of inspection parameters is to control product quality in real time. The real-time parameters are converted into historical parameters through the above method and processed, and the results are stored in the data processing module as historical parameters. However, when the parameters are judged to be out of limit, the control parameters need to be adjusted accordingly so that the subsequent inspection parameters can be controlled. Therefore, a parameter automatic adjustment module is set.

[0072] The parameter automatic adjustment module is an intervention behavior of the system after the parameter calculation exceeds the limit. However, the parameter automatic adjustment system is an adjustment behavior of the factory parameters based on the underlying control system, so it is necessary to solve the problems of authority priority, control period, etc.

[0073] The control module is set with the lowest priority, and the control module is triggered by reading the over-limit flag in the parameter calculation module. When the parameter calculation module calculates the parameters and determines whether it is out of limit, the over-limit flag is output to the control module through the pin. After the control module reads the over-limit flag, the module is enabled and communicates with the parameter calculation module to read the specific control value. Parameter control intervention is performed based on the read control value, and intervention conditions are judged before intervention. When it is detected that the intervention object is currently in an idle state and there is an over-limit flag, a temporary control instruction can be output to adjust the controlled parameter. When the parameter reaches the predetermined target allowable error range, the over-limit flag disappears and the intervention process is interrupted. In particular, when the system automatically adjusts when the module is participating in the intervention, the intervention authority is released immediately. If Figure 5shown.
