The application also provides an automatic comparison and calibration method for the consistency of the comprehensive test platform, which utilizes any one automatic comparison and calibration system for the consistency of the comprehensive test platform and comprises the following steps:
s1, after the cigarette or filter stick online production machine enters stable production, the controller sends an instruction to an automatic sampling device of the online production machine B1 for online sampling. The determination method for the online production machine to enter the steady-state production includes various determination methods, for example, taking time as a node, indicating that the online production machine enters the steady-state production after the device is started and operated for a long time (for example, 5 minutes), or determining that the online production machine enters the steady-state production by multiple active sampling, or determining that the online production machine enters the steady-state production by other methods, and the technical scheme of the present application does not need to protect the steady-state production machine, and how to determine the online production machine does not belong to the technical scope protected by the present application, and a person skilled in the art can determine that the online production machine enters the steady-state production.
And S2, after the automatic sampling device of the online production machine B1 finishes sampling, the conveying device alternately conveys samples to the upper-level comprehensive test bench and the online comprehensive test bench C1 corresponding to the online production machine B1 (in order to ensure the randomness between the samples and the consistency of the two samples), and the upper-level comprehensive test bench and the online comprehensive test bench C1 transmit monitoring data to the controller in real time (the time intervals of sample transmission need to be consistent, but are more than or equal to the detection time of a single sample of the comprehensive test bench) until the upper-level comprehensive test bench and the online comprehensive test bench C1 finish sample detection.
And S3, according to the received detection data of the upper-level comprehensive test bench and the online comprehensive test bench C1, the controller firstly adopts a mean square error (box chart, DBSCAN cluster, isolated Forest or Robust Random Cut Forest and the like) statistical method to respectively detect and remove abnormal data in the detection data of the upper-level comprehensive test bench and the online comprehensive test bench C1. The Kappa test (Hartley test, bartlett test, modified Bartlett test, etc) was then used to test the fluctuating consistency (homogeneity of variance) of the two sets of data, for which the following three cases of results were obtained:
the first result is that there is no obvious difference between the two sets of data, the consistency is good, therefore, the detection between the superior comprehensive test platform and the online comprehensive test platform C1 is consistent, and no calibration is needed, at this time, the controller ends the calibration between the superior comprehensive test platform and the online comprehensive test platform C1, and then the calibration between the superior comprehensive test platform and the online comprehensive test platform C2, the calibration between the online comprehensive test platform C3 \8230, and the calibration between the online comprehensive test platform Cn are performed.
The second result is that there is a significant difference between the two sets of data, and this difference is outside the set range, indicating that one of the sets of test equipment is malfunctioning, the controller sends a command to the remote control room to notify maintenance personnel to perform maintenance on the test equipment.
The third result is that there is a difference between the two sets of data, but the difference is within a set range, which still falls outside the set criteria, and the controller proceeds to step S4 while sending a maintenance instruction to the remote control room.
And S4, the controller sends an instruction to an automatic sampling device of the online production machine B2 for online sampling, after sampling is completed, the conveying device alternately conveys samples to an online comprehensive test board C2 corresponding to the superior comprehensive test board and the online production machine B2, and the superior comprehensive test board and the online comprehensive test board C2 transmit monitoring data to the controller in real time until the superior comprehensive test board and the online comprehensive test board C2 complete sample detection.
And S5, detecting the fluctuation consistency of the two groups of data detected in the step S4 by the controller according to the detection data in the step S4 by using the data processing method in the step S3, wherein the results still have the three results in the step S3, if the results are the same as the second results in the step S3, the adopted processing mode is the same as the processing mode corresponding to the step S3, and sending an instruction to a remote control room by the controller to inform maintenance personnel of maintaining the platform detection equipment. If the third result is the same as that in step S3, the controller performs the operation on the part corresponding to the third online production machine B3 by using the control method in step S4, that is:
the controller sends an instruction to an automatic sampling device of the online production machine B3 for online sampling, after sampling is completed, the conveying device alternately conveys samples to an upper comprehensive test platform and an online comprehensive test platform C3 corresponding to the online production machine B3, and the upper comprehensive test platform and the online comprehensive test platform C3 transmit monitoring data to the controller in real time until the upper comprehensive test platform and the online comprehensive test platform C3 complete sample detection. And then, the operation is carried out in the mode of the step S5 until the fluctuation consistency of the two groups of detection data of the online comprehensive test bench Cn corresponding to the online production bench Bn and the superior comprehensive test bench.
S6, the result of the two groups of data detection is the first result of the step S3, namely the two groups of data of the superior comprehensive test platform and the online comprehensive test platform C2 have no obvious difference and are good in consistency. The controller automatically modifies and corrects the online comprehensive test bench C1 by taking the density distribution center (mean value, median and other statistical methods) of the detection results of the upper comprehensive test bench as a reference according to the difference degree of the distribution centers of the two groups of data and by combining the allowable deviation evaluation standard of the comprehensive test bench, after the correction, the controller repeatedly sends an instruction to the automatic sampling device of the online production bench B1 to perform online sampling, and repeats the steps S2 to S6 until the consistency of the detection of the upper comprehensive test bench and the online comprehensive test bench C1 meets the evaluation standard, and then the step S7 is carried out.
And S7, by analogy, the controller sends instructions to the online production machines B2 and B3 \8230Bn, the corresponding sampling devices respectively perform sampling, and the corresponding online comprehensive test machines C2 and C3 \8230Cnperform consistency calibration on all the online comprehensive test machines and the superior comprehensive test machine according to the steps S2 to S6.
