[0034] In order to enable the person skilled in the art to better understand the technical solutions in the specification, the technical solutions in the specification will be clearly and completely described below in combination with the drawings in the specification. Obviously, the described embodiments are only part of the embodiments of the specification, not all. Based on the embodiments of the specification, all other embodiments obtained by the person skilled in the art without creative labor should be within the protection scope of the specification.

[0035] In the present application, when the proportion of carbon black in the conductive composite material of the heat tracing band is uneven, the determination of the test scheme under different lengths is carried out according to the uniform distribution, and the test results under different proportions of carbon black are used to realize the screening of the length with poor temperature control reliability, and then the manufacturing method of the heat tracing band is determined, so as to ensure the reliability of temperature control and the safety of operation of the heat tracing band.

[0036] Embodiment 1

[0037] As shown in Figure 1 , the present application provides a manufacturing method of an intelligent temperature control heat tracing band, which specifically comprises:

[0038] S1, based on the test data of the heat tracing band, determining the temperature measurement data of the heat tracing band, and based on the temperature measurement data, determining the distribution uniformity of the conductive composite material of the heat tracing band, and based on the distribution uniformity of the conductive composite material of the heat tracing band, determining the number of test samples of the heat tracing band at each length.

[0039] Further, the temperature measurement data of the heat tracing band includes the temperature measurement data of different temperature measurement points in the test process.

[0040] Specifically, as shown in Figure 2 , determining that the distribution uniformity of the conductive composite material of the heat tracing band is deviated, specifically comprising:

[0041] Based on the temperature measurement data, determining the temperature measurement data of different temperature measurement points in the test process of the heat tracing band;

[0042] Based on the temperature measurement data at different temperature measurement points, determining the distribution data of the abnormal temperature measurement points of the heat tracing band;

[0043] Using the distribution data of the abnormal temperature measurement points in the heat tracing band, determining the number of abnormal temperature measurement points in the heat tracing band, and according to the number of abnormal temperature measurement points in different heat tracing bands, determining whether the distribution uniformity of the conductive composite material of the heat tracing band is deviated.

[0044] It should be noted that when the average length of the heat tracing tape with the number of abnormal temperature measurement points greater than the preset temperature measurement point number threshold does not meet the requirements of the test process, it is determined that the distribution uniformity of the conductive composite material of the heat tracing tape is deviated.

[0045] In a possible embodiment, when the average length of the heat tracing tape with the number of abnormal temperature measurement points greater than 4 is less than 20 meters in the temperature measurement process, it is determined that the distribution uniformity of the conductive composite material of the heat tracing tape is deviated.

[0046] It can be understood that the distribution uniformity includes the test data of the abnormal temperature measurement points in the heat tracing tape at different lengths.

[0047] Specifically, as shown in Figure 3 The method for determining the number of test samples of the heat tracing tape at the length is:

[0048] Based on the distribution uniformity, the distribution data of the abnormal temperature measurement points of the heat tracing tape at different lengths in the test process is determined;

[0049] Based on the distribution data, the test process of the heat tracing tape with the number of abnormal temperature measurement points greater than the preset temperature measurement point number threshold at different lengths is determined as an abnormal test process.

[0050] Based on the proportion of the number of abnormal test processes at different lengths, the number of test samples of the heat tracing tape at the length is determined.

[0051] It should be noted that when the average value of the proportion of the number of abnormal test processes at different lengths does not meet the requirements, the number of test samples at different lengths is determined by the reference number.

[0052] In a possible embodiment, if the average value of the proportion of the number of abnormal test processes at different lengths is greater than 0.07, it is determined that the average value of the proportion of the number of abnormal test processes at different lengths does not meet the requirements.

[0053] It should be noted that the length includes 10m, 20m, 30m, 40m, 50m, and so on with an interval of 10 meters to 100m.

[0054] It should be noted that the number of test samples is the number of samples that are subjected to the observation and processing of the running temperature in the test process at different carbon black proportions.

[0055] Further, when the average of the number proportion of abnormal test processes at different lengths meets the requirement, it is further determined that the length at which the number proportion of abnormal test processes does not meet the requirement is less than the preset length threshold, and the number of test samples is determined by using the benchmark number at different lengths.

[0056] In addition, it can be understood that when there is no length at which the number proportion of abnormal test processes does not meet the requirement is less than the preset length threshold, the number of test samples is determined by using the benchmark number at the length at which the number proportion of abnormal test processes does not meet the requirement, and the number of test samples at the length at which the number proportion of abnormal test processes meets the requirement is determined according to the number proportion of abnormal test processes at the length.

[0057] It should be noted that the matching carbon black proportion is the carbon black proportion at which the conductive composite material does not have an abnormal temperature measurement point.

[0058] S2 determines, based on the number of test samples, that the test result of the matching carbon black proportion of the conductive composite material at each length meets the requirement, and determines the manufacturing method of the heat tracing band based on the similar situation of the matching carbon black proportion of the conductive composite material at each length and the resistivity data.

[0059] Specifically, as shown in FIG. 2, the test result of the matching carbon black proportion interval of the conductive composite material at each length is determined to meet the requirement, and specifically includes: Figure 4

[0060] determining the matching carbon black proportion data of the conductive composite material at the length;

[0061] determining whether the test result of the matching carbon black proportion interval of the conductive composite material at each length meets the requirement based on the matching carbon black proportion data and the number of test samples.

[0062] It can be understood that determining whether the test result of the matching carbon black proportion interval of the conductive composite material at each length meets the requirement based on the matching carbon black proportion data and the number of test samples specifically includes:

[0063] determining the matching proportion at each length based on the ratio of the number of matching carbon black proportions at the length to the number of test samples;

[0064] determining whether the test result of the matching carbon black proportion interval of the conductive composite material at each length meets the requirement based on the matching proportion at different lengths.

[0065] ​It should be noted that if the matching ratios at different test lengths are all greater than the preset matching ratio threshold, it is determined that the test result of the matching carbon black proportion interval of the conductive composite material at each length meets the requirement.

[0066] In a possible embodiment, if the matching ratios at different test lengths are all greater than 0.05, it is determined that the test result of the matching carbon black proportion interval of the conductive composite material at each length meets the requirement.

[0067] Specifically, as shown in Figure 5 The determined method of the manufacturing method of the heat tracing band is:

[0068] Based on the similar cases of the matching carbon black proportions of the conductive composite material at different lengths, it is determined that the matching carbon black proportion belongs to the matching carbon black proportion of the length, and the matching carbon black proportion is taken as the matching length. Based on the number of the matching lengths, the matching carbon black proportion with the largest number of matching lengths is determined as the available proportion.

[0069] According to the resistivity data of the available proportion, the unit resistance at different matching lengths in the available proportion is determined.

[0070] Based on the unit resistance at different lengths and the matching length data of the available proportion, the manufacturing method of the heat tracing band is determined.

[0071] It should be noted that when the unit resistance of the available proportion at different lengths does not meet the requirement or the number of matching lengths corresponding to the available proportion does not meet the requirement, the test processing at different lengths is continued until the matching carbon black proportion that meets the above conditions is obtained, that is, the unit resistance at different lengths meets the requirement and the number of matching lengths corresponding to the available proportion meets the requirement.

[0072] In a possible specific embodiment, when the unit resistance at different lengths is all less than 30 ohms and the number of matching lengths corresponding to the available proportion is not less than 4.

[0073] In addition, it should be noted that when the unit resistance of the available proportion at different lengths meets the requirement or the number of matching lengths corresponding to the available proportion meets the requirement, if the available proportion belongs to the matching carbon black proportion at all lengths at this time, the available proportion is taken as the manufacturing parameter, and the manufacturing processing of the heat tracing band is performed based on the manufacturing parameter.

[0074] It is further noted that if the available ratio does not belong to the matching carbon black ratio at all lengths, and if the number of the matching carbon black ratio corresponding to the length not belonging to the matching carbon black ratio at the available ratio does not meet the requirement, then the available ratio is taken as a manufacturing parameter, and the manufacturing process of the heat tracing band is carried out based on the manufacturing parameter, and the length not belonging to the matching carbon black ratio at the available ratio is no longer manufactured.

[0075] Further, if the number of the matching carbon black ratio corresponding to the length not belonging to the matching carbon black ratio at the available ratio does not meet the requirement, then it is determined that the test process is continued at different lengths until the matching carbon black ratio meeting the above conditions is obtained, that is, the number of the matching carbon black ratio corresponding to the length not belonging to the matching carbon black ratio at the available ratio does not meet the requirement or the available ratio belonging to the matching carbon black ratio at all lengths.

[0076] Embodiment 2

[0077] In a second aspect, the present application provides a smart temperature control heat tracing band, which adopts the manufacturing method of the smart temperature control heat tracing band, and includes:

[0078] The conductive composite material, the metal wire, the polyolefin insulation layer, the metal shielding layer, the outer sheath, the junction box and the joint.

[0079] Further, it is determined that the distribution uniformity of the conductive composite material of the heat tracing band is deviated, and specifically includes:

[0080] Based on the temperature measurement data, the temperature measurement data of different temperature measurement points of the heat tracing band in the test process is determined.

[0081] Based on the temperature measurement data of different temperature measurement points, the distribution data of the abnormal temperature measurement points of the heat tracing band is determined.

[0082] Using the distribution data, it is determined whether the distribution uniformity of the conductive composite material of the heat tracing band is deviated.

[0083] It can be understood that the abnormal temperature measurement point is a temperature measurement point whose deviation from the average value of the temperature measurement data of different temperature measurement points of the heat tracing band does not meet the requirement.

[0084] In one possible embodiment, if the deviation of the temperature measurement point from the average value of the temperature measurement data of different temperature measurement points of the heat tracing band is greater than 5 degrees Celsius, then the temperature measurement point is determined to be an abnormal temperature measurement point.

[0085] It can be understood that when the heat tracing band with the abnormal temperature measurement point exists in different test processes, it is determined that the distribution uniformity of the conductive composite material of the heat tracing band is deviated.

[0086] It should be noted that when the distribution of the conductive composite material of the heat tracing band is uniform, the manufacturing process of the heat tracing band is still carried out according to the original manufacturing method.

[0087] It should be noted that during the test, the heat tracing band is continuously operated at the rated voltage for 72 hours, and the temperature of different measurement points is measured by using the temperature measurement device during the test.

[0088] Embodiment 3

[0089] Further, the method for determining the number of test samples of the heat tracing band at the length is:

[0090] Based on the distribution data, the abnormal temperature measurement points of the heat tracing band at different lengths are determined.

[0091] Based on the distribution data, the abnormal temperature measurement points of the heat tracing band at different lengths are determined.

[0092] Based on the abnormal test process data at different lengths, the number of test samples of the heat tracing band at the length is determined.

[0093] It can be understood that the abnormal test process is the test process corresponding to the number of abnormal temperature measurement points of the heat tracing band at the length being greater than the preset threshold of the number of temperature measurement points.

[0094] It should be noted that when the proportion of the number of abnormal test processes does not meet the requirements of the length, the number of abnormal temperature measurement points at different lengths is small, and on this basis, the number of test samples at the length is determined according to the proportion of the number of abnormal test processes at the length.

[0095] In one possible embodiment, if the proportion of the number of abnormal test processes at different lengths in the test process is less than 0.05, it is determined that there is no length whose proportion of the number of abnormal test processes does not meet the requirements, and the number of test samples at the length is determined according to the product of the proportion of the number of abnormal test processes in the test process and a preset proportion coefficient, wherein the value of the preset proportion coefficient is 1000.

[0096] Further, when the length of the abnormal test process that does not meet the requirement occupies a proportion that does not meet the requirement, the maximum value of the proportion of the abnormal test process in different lengths is determined, and if the maximum value of the proportion of the abnormal test process in different lengths does not meet the requirement or the length of the abnormal test process that does not meet the requirement is less than the preset length threshold, the number of test samples in different lengths is determined by using the benchmark number.

[0097] In one possible embodiment, if the maximum value of the proportion of the abnormal test process in different lengths is greater than 0.1 or the length of the abnormal test process that does not meet the requirement is not greater than 20 meters, the number of test samples in different lengths is set to 100.

[0098] In addition, it can be understood that if the maximum value of the proportion of the abnormal test process in different lengths meets the requirement or the length of the abnormal test process that does not meet the requirement is not less than the preset length threshold, the proportion of the abnormal test process in the length of the abnormal test process that does not meet the requirement is determined as a weight value, and when the sum of the weight values of the abnormal test processes in different lengths that do not meet the requirement is greater than the preset weight threshold, the number of test samples in different lengths is determined by using the benchmark number.

[0099] In one possible embodiment, if the sum of the weight values of the abnormal test processes in different lengths that do not meet the requirement is greater than 0.2, the number of test samples in different lengths is determined by using the benchmark number.

[0100] In addition, it needs to be noted that when the sum of the weight values of the abnormal test processes in different lengths that do not meet the requirement is greater than the preset weight threshold, the number of test samples in the length of the abnormal test process that does not meet the requirement is determined by using the benchmark number, and in the length of the abnormal test process that meets the requirement, the number of test samples in the length is determined according to the proportion of the abnormal test process in the length.

[0101] Embodiment 4

[0102] Further, the method for determining the manufacturing method of the heat tracing band is:

[0103] On the basis of the similar proportion of the matching carbon black in the conductive composite material in different lengths, the length to which the proportion of the matching carbon black belongs is determined as the matching length.

[0104] According to the resistivity data of the matching carbon black proportion, the unit resistance of the matching carbon black proportion at different matching lengths is determined.

[0105] Based on the unit resistance at different matching lengths and the matching length data of the matching carbon black proportion, the manufacturing method of the heat tracing band is determined.

[0106] It should be noted that the unit resistance is the resistance per meter of the heat tracing band.

[0107] It can be understood that when there is a matching carbon black proportion at different lengths that belongs to the matching carbon black proportion and the unit resistance meets the requirements, the matching carbon black proportion at different lengths that belongs to the matching carbon black proportion and the unit resistance meets the requirements is taken as a manufacturing parameter, and the manufacturing process of the heat tracing band is carried out based on the manufacturing parameter.

[0108] In a possible embodiment, if the unit resistance is less than 30 ohms, it is determined that the unit resistance meets the requirements.

[0109] In addition, it should be noted that when there is no matching carbon black proportion at different lengths that belongs to the matching carbon black proportion and the unit resistance meets the requirements, the matching carbon black proportion whose unit resistance meets the requirements is obtained and taken as an alternative proportion, and when the number of matching lengths meets the requirements, the alternative proportion is taken as a target matching proportion, wherein when the number of target matching proportions does not meet the requirements, the test process is continued at different lengths until the number of target matching proportions meets the requirements or there is a matching carbon black proportion at different lengths that belongs to the matching carbon black proportion and the unit resistance meets the requirements.

[0110] In a possible specific embodiment, the alternative proportion whose number of matching lengths is not less than 3 is taken as the target matching proportion, and when the number of target matching proportions is more than 10, it is determined that the number of target matching proportions meets the requirements.

[0111] Further, when the number of target matching proportions meets the requirements, the number of target matching proportions corresponding to different matching lengths is obtained according to the matching length corresponding to the target matching proportion, and when the number of matching lengths whose number of target matching proportions is less than a preset target matching proportion number threshold does not meet the requirements, the test process is continued at different lengths until the number of target matching proportions meets the requirements or there is a matching carbon black proportion at different lengths that belongs to the matching carbon black proportion and the unit resistance meets the requirements.

[0112] In a possible embodiment, when the number of target matching ratios is less than 5 and the number of matching lengths is not less than 2, it is determined that the number of target matching ratios does not meet the requirement of the number of matching lengths.

[0113] In addition, it should be noted that when the number of matching lengths under different target matching ratios meets the requirement, if the number of target matching ratios corresponding to the matching lengths under the target matching ratios all meet the requirement, it is determined that the reliability of temperature control of the matching lengths under the target matching ratios all meet the requirement, and the target matching ratios are used as available matching ratios.

[0114] In a possible embodiment, if the number of target matching ratios corresponding to the matching lengths is not less than 5, it is determined that the number of target matching ratios corresponding to the matching lengths meets the requirement.

[0115] It should be noted that when the number of target matching ratios corresponding to the lengths that are not matching lengths under the available matching ratios all do not meet the requirement, the available matching ratios are used as manufacturing parameters, and the manufacturing process of the heat tracing band is performed based on the manufacturing parameters, and the lengths that are not matching lengths under the available matching ratios are not subjected to the manufacturing process.

[0116] In addition, it should be noted that when the number of target matching ratios corresponding to the lengths that are not matching lengths under the available matching ratios all do not meet the requirement, it is determined that the lengths that are not matching lengths under the available matching ratios may be omitted due to less test data, and the lengths that are matching lengths under the available matching ratios may be missed, and the test process is continued under different target matching ratios until the available matching ratios, in which the number of target matching ratios corresponding to the lengths that are not matching lengths all do not meet the requirement, are obtained.

[0117] It can be understood that, as the carbon black ratio increases, the unit resistance decreases, and the abnormal probability of over-temperature due to weakening of the PTC effect in the conductive composite material increases when unevenness occurs. At the same time, the decrease of the carbon black ratio may cause a large voltage attenuation at the end of the length, which may also increase the probability of occurrence of abnormal temperature measurement points. Therefore, the matching carbon black ratio under different lengths may have certain differences.

[0118] The various embodiments in this specification describe the application in progressive stages. Each stage builds upon the previous stages, and each stage can be described in terms of the differences between that stage and the previous stage. For example, the device, apparatus, and non-transitory computer storage medium embodiments are described more quickly because they are substantially similar to the method embodiments.
