[0003] L-shaped vacuum pipes are designed to be used for testing, using a vacuum or low pressure inside. They are suitable for a variety of high-speed transmission and precision manufacturing scenarios.

[0077] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0078] A temperature control method for an L-shaped vacuum pipeline is disclosed. The method obtains information on the type of test material, temperature detection information, jacket material information, and ambient temperature, analyzes the information, and determines temperature control information. The information is then output to a heating jacket preset on each section of the L-shaped vacuum pipeline for temperature adjustment. This allows the temperature of each section of the L-shaped vacuum pipeline to be controlled in real time, making the L-shaped vacuum pipeline less prone to clogging. Furthermore, the reference temperature is adjusted according to the ambient temperature and the jacket material to improve the accuracy of temperature control.

[0079] The embodiment of the present invention discloses a temperature control method for an L-shaped vacuum pipe. Figure 1 , an L-shaped vacuum pipeline temperature control method includes:

[0080] Step S100: Acquire test material type information and temperature detection information on each section of the L-shaped vacuum pipe.

[0081] The test material type information refers to the type of material within the L-shaped vacuum pipe when the test is conducted using the L-shaped vacuum pipe. This test material type information is obtained through operator input. The temperature detection information refers to the temperature detection information obtained by detecting the temperature of each section of the L-shaped vacuum pipe. This temperature detection information is obtained through detection by temperature sensors pre-installed in each section of the L-shaped vacuum pipe.

[0082] Step S200: Retrieve the temperature detection value and the detection location based on the temperature detection information.

[0083] Among them, the temperature detection information includes temperature detection values ​​and detection location points. The temperature detection values ​​refer to the temperature values ​​detected on each section of the L-shaped vacuum pipe, and the detection location points refer to the location points of the temperature detection values ​​on the L-shaped vacuum pipe. The temperature detection values ​​and detection location points are retrieved through the temperature detection information to facilitate subsequent use.

[0084] Step S300: Determine the temperature reference value based on the information of the detection location and the type of test material.

[0085] Among them, the temperature reference value refers to the reference value that the temperature needs to reach at different positions on the L-shaped vacuum pipe. By analyzing the detection location point and the test material type information, the temperature reference value is determined to facilitate subsequent use.

[0086] Step S400: Calculate the difference between the temperature detection value and the temperature reference value and use it as the temperature deviation value.

[0087] The temperature deviation value refers to the deviation value when the temperature at the detection location point deviates. The difference between the temperature detection value and the temperature reference value is calculated and used as the temperature deviation value for subsequent use.

[0088] Step S500: determining temperature control information based on the temperature deviation analysis, and outputting the temperature control information to the heating jackets preset on each section of the L-shaped vacuum pipe for temperature adjustment.

[0089] Among them, the temperature control information refers to the control information used to control the heating jackets preset on each section of the L-shaped vacuum pipeline to adjust the heating power. By analyzing the temperature deviation value, the temperature control information is determined and output to the heating jackets preset on each section of the L-shaped vacuum pipeline for temperature adjustment, so as to perform real-time control and adjustment based on the detected temperatures of different sections in the L-shaped vacuum pipeline, so that the temperatures of different sections in the L-shaped vacuum pipeline can meet the requirements, and finally achieve the effect of making the L-shaped vacuum pipeline less likely to be blocked.

[0090] exist Figure 1 In step S500, in order to further ensure the rationality of the temperature control information, it is necessary to further analyze and calculate the temperature control information. Figure 2 The steps shown are explained in detail.

[0091] Reference Figure 2 , the method for determining the temperature control information includes the following steps:

[0092] Step S510: Retrieve the type deviation reference interval based on the test material type information.

[0093] The type deviation reference interval refers to the reference interval corresponding to the allowable temperature deviation of the material type tested using the L-shaped vacuum tube. The type deviation reference interval can be stored in the database after the operator tests, or obtained by querying the relevant material website. The type deviation reference interval can be retrieved based on the test material type information for easy subsequent use.

[0094] Step S520: Determine whether the temperature deviation value is within the category deviation reference range. If yes, proceed to step S530; if not, proceed to step S540.

[0095] Here, by judging whether the temperature deviation value is within the type deviation reference interval, it is judged whether the temperature of the current section of the L-shaped vacuum pipe can be directly adjusted.

[0096] Step S530: determining temperature deviation adjustment information corresponding to the temperature deviation value according to a correspondence between the temperature deviation value and preset temperature deviation adjustment information, and using the temperature deviation adjustment information as temperature control information.

[0097] Among them, the temperature deviation adjustment information refers to the control information when the temperature of the heating jacket preset on the L-shaped vacuum pipe is adjusted according to the temperature deviation value. The temperature deviation adjustment information is obtained by querying from a database that stores the corresponding relationship between the temperature deviation value and the temperature deviation adjustment information. The database is obtained and stored through operator experiments.

[0098] When the temperature deviation value is within the type deviation reference range, it means that the temperature of the current section on the L-shaped vacuum pipe can be directly adjusted at this time. Therefore, the temperature deviation adjustment information is determined by querying the temperature deviation value, and the temperature deviation adjustment information is used as the temperature control information, thereby improving the accuracy of the obtained temperature control information.

[0099] Step S540: Calculate the difference between the temperature deviation value and the type deviation reference interval and use it as the temperature excess deviation value.

[0100] Among them, the temperature excess deviation value refers to the deviation value when the temperature has excess deviation. When the temperature deviation value is not within the type deviation reference interval, it means that the temperature of the current section on the L-shaped vacuum pipe cannot be directly adjusted at this time. Therefore, the difference between the temperature deviation value and the type deviation reference interval is calculated and used as the temperature excess deviation value for subsequent use.

[0101] Step S550: Retrieve the excess deviation duration value based on the temperature excess deviation value.

[0102] The excess deviation duration value refers to the time value corresponding to the continued existence of the excess deviation. By counting the duration corresponding to the temperature excess deviation value and retrieving it as the excess deviation duration value, it is convenient for subsequent use.

[0103] Step S560: Determine excess deviation adjustment information according to the excess temperature deviation value and the excess deviation duration value, and use the excess deviation adjustment information as temperature control information.

[0104] Among them, the excess deviation adjustment information refers to the control information when the temperature is adjusted by the heating jacket preset on the L-shaped vacuum pipe based on the excess deviation control. By analyzing the temperature excess deviation value and the excess deviation duration value, the excess deviation adjustment information is determined and used as the temperature control information, thereby improving the accuracy of the obtained temperature control information.

[0105] exist Figure 2 In step S560, in order to further ensure the rationality of the redundant deviation adjustment information, it is necessary to further analyze and calculate the redundant deviation adjustment information separately, specifically by Figure 3 The steps shown are explained in detail.

[0106] Reference Figure 3 , the method for determining the redundant deviation adjustment information includes the following steps:

[0107] Step S561: Based on the detection position point, retrieve the temperature detection value of the adjacent position and use it as the adjacent temperature value.

[0108] Among them, the adjacent temperature value refers to the temperature detection value corresponding to the position adjacent to the detection position point. By retrieving the temperature detection value corresponding to the adjacent position of the detection position point and using it as the adjacent temperature value, it is convenient for subsequent use.

[0109] Step S562: determining an adjacent temperature influence value corresponding to the adjacent temperature value according to a correspondence between the adjacent temperature value and the preset adjacent temperature influence value.

[0110] The adjacent temperature impact value refers to the degree of influence of the temperature at the adjacent location on the temperature at the detection location. The adjacent temperature impact value is obtained by querying from a database that stores the corresponding relationship between adjacent temperature values ​​and adjacent temperature impact values. This database is obtained and stored through operator experiments. Determining the adjacent temperature impact value through the adjacent temperature value query facilitates subsequent use.

[0111] Step S563: Calculate the sum of the temperature excess deviation value and the adjacent temperature impact value and use it as the temperature adjacent adjustment value.

[0112] Among them, the temperature adjacent adjustment value refers to the deviation value after the temperature of the adjacent position is adjusted for the excess deviation. The sum of the temperature excess deviation value and the adjacent temperature influence value is calculated and used as the temperature adjacent adjustment value for convenience of subsequent use.

[0113] Step S564: Analyze and determine temperature adjacent adjustment information based on the temperature adjacent adjustment values.

[0114] Among them, the temperature adjacent adjustment information refers to the control information for controlling the temperature adjustment of the detection position point and the heating jacket at the adjacent position according to the temperature adjacent adjustment value. The temperature adjacent adjustment information is determined by analyzing the temperature adjacent adjustment value to facilitate subsequent use.

[0115] Furthermore, in order to improve the accuracy of the acquired temperature adjacent adjustment information, the method for determining the temperature adjacent adjustment information includes the following steps:

[0116] Step S5641: Calculate the quotient between the temperature adjacent adjustment value and the preset temperature adjustment reference rate value and use it as the temperature adjustment time value at the current position.

[0117] The "temperature adjustment reference rate" is the reference rate at which temperature can be adjusted per unit time during temperature adjustment. This value is pre-entered by the operator and obtained. The "current position temperature adjustment time" is the time required to adjust the temperature at the current position. The quotient between the adjacent temperature adjustment values ​​and the preset temperature adjustment reference rate is calculated and used as the current position temperature adjustment time for subsequent use.

[0118] Step S5642: Determine the current position temperature adjustment information corresponding to the temperature adjacent adjustment value and the current position temperature adjustment time value according to the correspondence between the temperature adjacent adjustment value, the current position temperature adjustment time value and the preset current position temperature adjustment information.

[0119] The current location temperature adjustment information refers to adjustment information for adjusting the temperature at the current location. The current location temperature adjustment information is obtained by querying a database that stores the corresponding relationships between adjacent temperature adjustment values, current location temperature adjustment time values, and current location temperature adjustment information. The database is pre-entered by the operator and then obtained. The current location temperature adjustment information is determined by querying the adjacent temperature adjustment values ​​and the current location temperature adjustment time values ​​to facilitate subsequent use.

[0120] Step S5643: Calculate the difference between the adjacent temperature value and the adjacent temperature adjustment value and use it as the adjacent temperature adjustment value.

[0121] Among them, the adjacent temperature adjustment value refers to the temperature value that needs to be adjusted when adjusting the temperature of adjacent positions. By calculating the difference between the adjacent temperature value and the adjacent temperature adjustment value and using it as the corresponding relationship of the adjacent temperature adjustment value, it is convenient for subsequent use.

[0122] Step S5644: Calculate the quotient between the adjacent temperature adjustment value and the current position temperature adjustment time value and use it as the adjacent temperature rate adjustment value.

[0123] Among them, the adjacent temperature rate adjustment value refers to the rate value that needs to be achieved when adjusting the temperature of the adjacent position. The quotient between the adjacent temperature adjustment value and the current position temperature adjustment time value is calculated and used as the adjacent temperature rate adjustment value, which is convenient for subsequent use.

[0124] Step S5645: Determine the adjacent position temperature adjustment information corresponding to the adjacent temperature adjustment value and the adjacent temperature rate adjustment value according to the corresponding relationship between the adjacent temperature adjustment value, the adjacent temperature rate adjustment value and the preset adjacent position temperature adjustment information.

[0125] The adjacent position temperature adjustment information refers to adjustment information for adjusting the temperature of adjacent positions. The adjacent position temperature adjustment information is obtained by querying a database storing the correspondence between adjacent temperature adjustment values, adjacent temperature rate adjustment values, and adjacent position temperature adjustment information. The database is obtained after pre-entry by the operator. The adjacent position temperature adjustment information is determined by querying the adjacent temperature adjustment values ​​and adjacent temperature rate adjustment values ​​to facilitate subsequent use.

[0126] Step S5646: Combine the current position temperature adjustment information and the adjacent position temperature adjustment information to form adjacent temperature adjustment information.

[0127] The temperature adjustment information of the current position and the temperature adjustment information of the adjacent position are combined and used as the temperature adjacent adjustment information, thereby improving the accuracy of the obtained temperature adjacent adjustment information.

[0128] Step S565: Determine whether the excess deviation duration value is less than a preset reference duration value. If yes, execute step S566; if no, execute step S567.

[0129] The duration reference value is the minimum duration of the excess deviation when an abnormality occurs. This value is pre-entered by the operator and is obtained. By determining whether the excess deviation duration value is less than the preset duration reference value, it is determined whether the temperature adjustment of the adjacent position can be adopted.

[0130] Step S566: Use the temperature adjacent adjustment information as redundant deviation adjustment information.

[0131] Among them, when the excess deviation duration value is less than the preset duration reference time 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 excess deviation adjustment information, thereby improving the accuracy of the obtained excess deviation adjustment information.

[0132] Step S567: Calculate the difference between the excess deviation duration value and the reference duration value and use it as the duration deviation value.

[0133] 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.

[0134] Step S568: Determine the abnormality cause information based on the duration deviation value and the temperature excess deviation value analysis.

[0135] Among them, 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.

[0136] Step S569: Determine the abnormality adjustment information corresponding to the abnormality cause information according to the correspondence between the abnormality cause information and the preset abnormality adjustment information, and use the abnormality adjustment information as the redundant deviation adjustment information.

[0137] Abnormal adjustment information refers to adjustment information based on the cause of the abnormality. Abnormal adjustment information is obtained by querying a database that stores the correspondence between abnormal cause information and abnormal adjustment information. This database is obtained after pre-entry by the operator. Abnormal adjustment information is determined through the abnormal cause information query and used as excess deviation adjustment information, thereby improving the accuracy of the obtained excess deviation adjustment information.

[0138] exist Figure 3 In step S568, in order to further ensure the rationality of the abnormal cause information, it is necessary to further analyze and calculate the abnormal cause information. Figure 4 The steps shown are explained in detail.

[0139] Reference Figure 4 , the method for determining the abnormal cause information includes the following steps:

[0140] Step S5681: Based on the duration deviation value, a match is searched from a preset time deviation cause database to obtain information on the initial cause of the time deviation.

[0141] The time deviation cause database refers to a database that stores the correspondence between time deviations and their corresponding causes. The time deviation cause database is obtained through operator input. The initial time deviation cause information refers to the initial cause information selected based on the time deviation. This initial time deviation cause information is obtained by searching the time deviation cause database preset based on the duration deviation value, thereby facilitating subsequent use.

[0142] Step S5682: Retrieve the initial cause excess deviation interval based on the time deviation initial cause information.

[0143] Among them, the initial cause excess deviation interval refers to the reference interval corresponding to the excess deviation in the initial cause. The initial cause excess deviation interval is retrieved through the time deviation initial cause information to facilitate subsequent use.

[0144] Step S5683: Determine the redundant deviation selection reason information based on whether the temperature redundant deviation value falls within the initial cause redundant deviation interval.

[0145] Among them, the redundant deviation selection reason information refers to the reason information after the reason is selected based on the temperature redundant deviation value. By analyzing the falling situation between the temperature redundant deviation value and the initial cause redundant deviation interval, the time deviation initial cause information corresponding to the temperature redundant deviation value falling into the initial cause redundant deviation interval is used as the redundant deviation selection reason information, which is convenient for subsequent use.

[0146] Step S5684: Retrieve the selection reason value based on the redundant deviation selection reason information.

[0147] Among them, the selected cause value refers to the value corresponding to the cause after the cause is selected based on the temperature excess deviation value. The number corresponding to the excess deviation selected cause information is counted, and the counting result is retrieved as the selected cause value for subsequent use.

[0148] Step S5685: Determine whether the selected reason value is only one. If yes, execute step S5686; if no, execute step S5687.

[0149] Here, it is determined whether the selection reason has only one value, thereby determining whether it is necessary to continue the selection.

[0150] Step S5686: The redundant deviation selection reason information is used as the abnormal reason information.

[0151] Among them, when the number of selection reasons is only one, it means that there is no need to continue selection at this time, so the redundant deviation selection reason information is used as abnormal reason information.

[0152] 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.

[0153] Among them, when the number of selection reasons is not just one, it means that the selection needs to continue at this time, so the initial cause excess deviation interval corresponding to the excess deviation selection reason information is used as the selection cause excess deviation interval, thereby defining the selection cause excess deviation interval for easy subsequent use.

[0154] 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.

[0155] Among them, the final selection reason information refers to the reason information for the final selection. By analyzing the temperature excess deviation value and the selection reason excess deviation interval, the final selection reason information is determined, and the final selection reason information is used as the abnormal reason information to improve the accuracy of the acquired abnormal reason information.

[0156] exist Figure 4 In step S5688, in order to further ensure the rationality of the final selection reason information, it is necessary to further analyze and calculate the final selection reason information separately, specifically through Figure 5 The steps shown are explained in detail.

[0157] Reference Figure 5,The method for determining the final selection reason information includes the following steps:

[0158] Step S56881: Calculate the difference between the temperature excess deviation value and the selected reason excess deviation interval and use it as the interval deviation value.

[0159] Among them, the interval deviation value refers to the deviation value corresponding to the deviation from the interval. The difference between the temperature excess deviation value and the selection reason excess deviation interval is calculated and used as the interval deviation value to facilitate subsequent use.

[0160] Step S56882: Calculate the difference between the two end values ​​of the selection reason excess deviation interval and use it as the selection interval range value.

[0161] Among them, the selection interval range value refers to the range value corresponding to the selection reason excess deviation interval. The difference between the two end values ​​of the selection reason excess deviation interval is calculated and used as the selection interval range value to facilitate subsequent use.

[0162] Step S56883: Determine the selection interval range influence value corresponding to the selection interval range value according to the correspondence between the selection interval range value and the preset selection interval range influence value.

[0163] The selected interval impact value refers to the degree of impact caused by the size of the range corresponding to the selection cause excess deviation interval. The selected interval impact value is obtained by querying a database that stores the correspondence between selected interval values ​​and selected interval impact values. This database is obtained after pre-entry by the operator. The selected interval impact value is determined by querying the selected interval value for subsequent use.

[0168] exist Figure 1 In step S300, 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 6 The steps shown are explained in detail.

[0169] Reference Figure 6 , the method for determining the temperature reference value includes the following steps:

[0170] Step S310: Retrieve the type temperature initial value, position distance influence value, and adjacent temperature influence value based on the test material type information.

[0171] The Type Temperature Initial Value refers to the initial temperature value required for the type of material being tested, the Position Distance Impact Value refers to the degree of influence of distance on the required temperature of the type of material being tested, and the Adjacent Temperature Impact Value refers to the degree of influence of adjacent temperatures on the required temperature of the type of material being tested. The Type Temperature Initial Value, Position Distance Impact Value, and Adjacent Temperature Impact Value can be retrieved using the test material type information for easy subsequent use.

[0172] 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.

[0173] The reference position point refers to the position point corresponding to the bend in the L-shaped vacuum pipe during the test. The reference position point is obtained through pre-entry 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 negative. When the detection deviation distance value is opposite to the flow direction of the material during the test, the detection deviation distance value is positive. 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.

[0174] Step S330 : analyzing and determining a 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 using the type temperature adjustment value as the temperature reference value.

[0175] 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, position distance influence value, adjacent temperature influence value, detection deviation distance value and 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.

[0176] Methods for determining the temperature adjustment value of a type include:

[0177] The type temperature adjustment value is obtained by calculating 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 based on a preset type temperature adjustment value calculation formula.

[0178] The temperature adjustment value calculation formula is a formula used to calculate the temperature adjustment value of a certain type. The temperature adjustment value calculation formula is obtained after the operator pre-enters it. , is the temperature adjustment value of the species, is the initial value of species temperature, is the position distance influence value, is the adjacent temperature influence value, To detect the deviation distance value, are adjacent temperature values, is the temperature detection value.

[0179] For example, when When the temperature adjustment value is .

[0180] 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.

[0181] Reference Figure 7 The steps after taking the temperature adjustment value of the species as the temperature reference value include the following steps:

[0182] Step S331: Obtain the jacket material information and ambient temperature value of the heating jacket.

[0183] The jacket material information refers to the type of material used by the heating jacket, and is obtained through operator input. The ambient temperature value refers to the temperature of the environment in which the L-shaped vacuum pipe under test is located at the current time. The ambient temperature value can be obtained by querying a local temperature website at the current time, or by querying a temperature sensor pre-set at the location of the L-shaped vacuum pipe.

[0184] Step S332: Retrieve the material insulation impact value based on the jacket material information.

[0185] Among them, the material insulation impact value refers to the degree of influence of the material type of the heating jacket on the insulation. The material insulation impact value is retrieved through the jacket material information, which is convenient for subsequent use.

[0186] 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.

[0187] 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.

[0188] 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.

[0189] The temperature environment deviation reference interval refers to the reference interval within which deviations can be tolerated based on the type temperature adjustment value. The temperature environment deviation reference interval is retrieved by querying a database that stores the correspondence between type temperature adjustment values ​​and temperature environment deviation reference intervals. This database is retrieved after user input. Determining the temperature environment deviation reference interval by querying the type temperature adjustment value facilitates subsequent use.

[0190] Step S335: Determine whether the temperature environment deviation value is within the temperature environment deviation reference range. If yes, execute step S336; if not, execute step S337.

[0191] 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.

[0192] Step S336: Continue to output the temperature reference value.

[0193] When the temperature environment deviation value is within the temperature environment deviation reference range, it indicates that the ambient temperature has no influence at this time, so the temperature reference value continues to be output.

[0194] Step S337: Calculate the sum of the temperature environment deviation value and the material thermal 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.

[0195] 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 range, 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.
