[0066] The duration reference time value refers to the minimum duration of the excess deviation when an abnormality exists, and the duration reference time value is obtained after being pre-entered by the operator. By judging whether the excess deviation duration value is less than the preset duration reference time value, it is judged whether the temperature adjustment of the adjacent position can be adopted.

[0067] Step S566: Use the temperature adjacent adjustment information as redundant deviation adjustment information.

[0068] Among them, when the redundant deviation duration value is less than the preset reference duration value, it means that the temperature adjustment of the adjacent position can be adopted at this time, so the temperature adjacent adjustment information is used as the redundant deviation adjustment information, thereby improving the accuracy of the obtained redundant deviation adjustment information.

[0070] Among them, the duration deviation value refers to the deviation value corresponding to the existence of excess duration. When the excess deviation duration value is not less than the preset duration reference time value, it means that the temperature adjustment of the adjacent position cannot be used at this time. Therefore, the difference between the excess deviation duration value and the duration reference time value is calculated and used as the duration deviation value for subsequent use.

[0071] Step S568: Determine the abnormal cause information based on the duration deviation value and the temperature excess deviation value analysis.

[0072] The abnormal cause information refers to the cause information corresponding to the abnormal duration. By analyzing the duration deviation value and the temperature excess deviation value, the abnormal cause information is determined to facilitate subsequent use.

[0085] Here, it is determined whether the selection needs to be continued by judging whether the number of selection reasons is only one.

[0086] Step S5686: Select the excess deviation reason information as the abnormal reason information.

[0087] Among them, when the value of the selection reason is only one, it means that there is no need to continue the selection at this time, so the redundant deviation selection reason information is used as the abnormal reason information.

[0088] Step S5687: The initial cause excess deviation interval corresponding to the excess deviation selection reason information is used as the selection cause excess deviation interval.

[0089] Among them, when the number of selected reasons is not only one, it means that the selection needs to continue at this time, so the initial reason excess deviation interval corresponding to the excess deviation selection reason information is used as the selection reason excess deviation interval, thereby defining the selection reason excess deviation interval for subsequent use.

[0090] Step S5688: Determine the final selection reason information based on the temperature excess deviation value and the selection reason excess deviation interval analysis, and use the final selection reason information as the abnormal reason information.

[0104] Reference Figure 6 , the method for determining the temperature reference value includes the following steps: Step S310: Retrieve the type temperature initial value, the position distance influence value and the adjacent temperature influence value based on the test material type information.

[0105] Among them, the type temperature initial value refers to the initial temperature value required for the type of material being tested, the position distance influence value refers to the influence degree value corresponding to the temperature required by the type of material being tested being affected by the distance, and the adjacent temperature influence value refers to the influence degree value corresponding to the temperature required by the type of material being tested being affected by the adjacent temperature. The type temperature initial value, position distance influence value and adjacent temperature influence value are retrieved through the test material type information for easy subsequent use.

[0106] Step S320: Calculate the distance between the detection position point and the preset reference position point and use it as the detection deviation distance value.

[0107] Among them, the reference position point refers to the position point corresponding to the bend in the L-shaped vacuum pipe during the test, and the reference position point is obtained after pre-input by the operator. The detection deviation distance value refers to the parameter value of the distance and direction between the detection position point and the reference position point. When the flow direction of the material from the detection position point to the reference position point is consistent with the flow direction of the test, the detection deviation distance value is a negative value. When the detection deviation distance value is opposite to the flow direction of the material during the test, the detection deviation distance value is a positive value. By calculating the distance between the detection position point and the preset reference position point and using it as the detection deviation distance value, it is convenient for subsequent use.

[0108] Step S330: Analyze and determine the type temperature adjustment value according to the type temperature initial value, the position distance influence value, the adjacent temperature influence value, the detection deviation distance value and the adjacent temperature value, and use the type temperature adjustment value as the temperature reference value.

[0109] Among them, the type temperature adjustment value refers to the temperature value after the temperature is adjusted according to the type. The type temperature adjustment value is determined by analyzing the type temperature initial value, the position distance influence value, the adjacent temperature influence value, the detection deviation distance value and the adjacent temperature value, and the type temperature adjustment value is used as the temperature reference value to improve the accuracy of the obtained type temperature adjustment value.

[0110] Methods for determining the temperature adjustment value of a type include: Based on the preset type temperature adjustment value calculation formula, the type temperature initial value, the position distance influence value, the adjacent temperature influence value, the detection deviation distance value and the adjacent temperature value are calculated to obtain the type temperature adjustment value.

[0113] exist Figure 6 After step S330, in order to further ensure the rationality of the temperature reference value, it is necessary to further analyze and calculate the temperature reference value. Figure 7 The steps shown are explained in detail.

[0114] Reference Figure 7 The steps after taking the temperature adjustment value of the species as the temperature reference value include the following steps: Step S331: Obtain the jacket material information and ambient temperature value of the heating jacket.

[0115] The jacket material information refers to the type of material of the heating jacket, and the jacket material information is obtained after being pre-input by the operator. The ambient temperature value refers to the temperature value of the environment in which the L-shaped vacuum pipe under test is located at the current time, and the ambient temperature value can be obtained by querying the temperature website of the place at the current time, or by querying the temperature sensor preset at the location of the L-shaped vacuum pipe.

[0116] Step S332: Retrieve the material thermal insulation impact value based on the jacket material information.

[0117] Among them, the material thermal insulation impact value refers to the degree of influence of the material type of the heating jacket on the thermal insulation. The material thermal insulation impact value is retrieved through the jacket material information, which is convenient for subsequent use.

[0118] Step S333: Calculate the difference between the type temperature adjustment value and the ambient temperature value and use it as the temperature environment deviation value.

[0119] Among them, the temperature environment deviation value refers to the deviation value when the temperature is adjusted according to the type and deviates from the ambient temperature. The difference between the type temperature adjustment value and the ambient temperature value is calculated and used as the temperature environment deviation value for convenience in subsequent use.

[0120] Step S334: determining the temperature environment deviation reference interval corresponding to the type temperature adjustment value according to the correspondence between the type temperature adjustment value and the preset temperature environment deviation reference interval.

[0121] The temperature environment deviation reference interval refers to the reference interval that can tolerate the deviation according to the type temperature adjustment value. The temperature environment deviation reference interval is obtained by querying from a database storing the corresponding relationship between the type temperature adjustment value and the temperature environment deviation reference interval. The database is obtained after the operator pre-enters. The temperature environment deviation reference interval is determined by querying the type temperature adjustment value, which is convenient for subsequent use.

[0122] Step S335: Determine whether the temperature environment deviation value is within the temperature environment deviation reference interval. If yes, execute step S336; if no, execute step S337.

[0123] Whether the ambient temperature has an impact is determined by determining whether the temperature environment deviation value is within the temperature environment deviation reference interval.

[0124] Step S336: Continue to output the temperature reference value.

[0125] When the temperature environment deviation value is within the temperature environment deviation reference interval, it means that the ambient temperature has no influence at this time, so the temperature reference value continues to be output.

[0126] Step S337: Calculate the sum of the temperature environment deviation value and the material insulation impact value and use it as the environment temperature impact value, and add the environment temperature impact value to the temperature reference value to form a new temperature reference value.

[0127] Among them, the ambient temperature impact value refers to the impact degree value when the ambient temperature has an impact. When the temperature environment deviation value is not within the temperature environment deviation reference interval, it means that the ambient temperature has an impact at this time. Therefore, the sum of the temperature environment deviation value and the material insulation impact value is calculated and used as the ambient temperature impact value, and the ambient temperature impact value is added to the temperature reference value to form a new temperature reference value, thereby improving the accuracy of the obtained temperature reference value.
