Description

Technical Field

[0001] This invention relates to the field of composite cable testing technology, specifically to a factory condition testing system and method for optoelectronic composite cables. Background Technology

[0002] Optical-optical composite cables are transmission lines used in broadband access network systems. They represent a new type of access method, integrating optical fiber and copper power transmission wire to solve problems related to broadband access, equipment power supply, and signal transmission. The versatility of optical-optical composite low-voltage cables (referred to as optical-optical composite cables) necessitates a complex cable structure. However, with a reasonable structural design, the functions of the composite cable can be better realized and satisfied, while meeting manufacturing standards and reducing manufacturing costs to maximize efficiency. The structure of a composite cable typically consists of two main parts: a stranded cable core and a sheath. The sheath includes a protective sheath and an outer sheath, the latter being optional.

[0003] Because of the complex composition of fiber optic composite cables, the factory testing of these cables includes not only routine mechanical structure performance testing and sheathing material testing, but also optical power testing of the fiber optic portion and electrical performance testing of the copper conductor portion. While common optical cables or electrical cables only require optical power or electrical performance testing, fiber optic composite cables, combining both functions, require both tests simultaneously.

[0004] In the existing testing process for optical fiber composite cables, the testing equipment is limited by the inability to simultaneously complete optical power testing or electrical performance testing. Therefore, the test samples are often subjected to one test first, and then another test; or the test samples are divided into two batches, each subjected to one test, and then the test items are switched after completion, making the entire testing process quite cumbersome. Summary of the Invention

[0005] The purpose of this invention is to provide a factory condition testing system and method for optoelectronic composite cables, thereby solving the aforementioned technical problems.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A factory condition inspection system and method for optical fiber composite cables includes the following steps:

[0008] The optical fiber composite cable to be tested is divided into several testing batches, wherein the optical fiber composite cable in each testing batch is a product manufactured in the same production batch.

[0009] According to the preset sampling rules, several test samples are randomly selected from the same batch of tests and numbered; and after being divided into two test groups, optical power test and electrical performance test are performed respectively.

[0010] The test results of one of the test groups are taken as the first test sample, and the standard output value Stdout is calculated based on the number of "unqualified" test results in the first test sample. The calculation method is as follows:

[0011]

[0012] Where N represents the total number of samples in the first test sample, n represents the number of "non-compliant" samples in the first test sample, ΔX represents the number of other test results between any two adjacent "non-compliant" test results, and A represents the preset correction value, A≥0;

[0013] The calculated standard output value Stdout is rounded down, and the number information of the test sample with the "unqualified" test result is selected as the target number based on the first test sample. With the target number as the center, other numbers on both sides are selected in sequence, the number of selections is the same as the standard output value Stdout, and the test sample corresponding to the selected number is located in another test group.

[0014] The test results of the selected number corresponding to the test sample are used as the second test sample, and the standard output value Stdout is corrected by the second test sample to calculate the secondary output value Stdout'.

[0015] Reselect numbers centered on the target number, with the same number as the secondary output value Stdout', and perform another test on the test sample corresponding to the selected number, and output the test results;

[0016] Replace the test results from another test group with the first test sample and repeat the above process.

[0017] As a further aspect of the present invention, the specific method for dividing test samples from the same batch into two test groups is as follows:

[0018] The test samples are sorted according to the production completion time and numbered according to the sorting position, with the earlier the production completion time, the higher the sorting position.

[0019] The sorted test samples were stratified according to the number of test groups, and the test samples were divided into two groups by cross-selection.

[0020] The two groups of test samples are defined as test groups.

[0021] As a further aspect of the present invention: in the first test sample, the order of the test results is the same as the order in the corresponding test group.

[0022] As a further aspect of the present invention: during the process of selecting numbers on both sides with the target number as the center, when a certain number is selected by two or more target numbers, only one item is retained when generating the second test sample, and other identical items are deleted.

[0023] As a further aspect of the present invention: the specific method for correcting the standard output value Stdout using a second test sample to calculate the secondary output value Stdout' is as follows:

[0024] Obtain the test results and standard output value Stdout from the second test sample;

[0025] The formula for calculating the secondary output value Stdout' is as follows:

[0026]

[0027] Where ΔS represents the number of test samples whose numbers correspond to any two adjacent "non-compliant" test results in the first test sample are located in another test group, n' represents the number of "non-compliant" samples in the second test sample, N' represents the total number of samples in the second test sample, and K represents the preset retention coefficient, where K < 1.

[0028] As a further aspect of the present invention: when the defect interval value If the value is greater than or equal to the standard output value Stdout, then all test samples from another test group are directly acquired for another test, and the test results are output.

[0029] As a further aspect of the present invention, it also includes obtaining all test results, and when any test sample is tested only once, the other test is assumed to be qualified; when any test sample fails one of its tests, the test sample is assumed to be unqualified.

[0030] A factory condition inspection system for an optical fiber composite cable, comprising:

[0031] Product segmentation module: Divides the optical fiber composite cable to be tested into several testing batches, wherein the optical fiber composite cable in each testing batch is a product manufactured in the same production batch;

[0032] According to the preset sampling rules, several test samples are randomly selected from the same batch of tests and numbered; and after being divided into two test groups, optical power test and electrical performance test are performed respectively.

[0033] First test module: Obtain the test results of one of the test groups as the first test sample, and calculate the standard output value Stdout based on the number of "unqualified" test results in the first test sample. The calculation method is as follows:

[0034]

[0035] Where N represents the total number of samples in the first test sample, n represents the number of "non-compliant" samples in the first test sample, ΔX represents the number of other test results between any two adjacent "non-compliant" test results, and A represents the preset correction value, A≥0;

[0036] The second testing module: rounds the calculated standard output value Stdout, and selects the number information of the test samples whose test results are "unqualified" based on the first test sample as the target number; with the target number as the center, other numbers on both sides are selected in sequence, the number of selections is the same as the standard output value Stdout, and the test samples corresponding to the selected numbers are located in another test group.

[0037] The test results of the selected number corresponding to the test sample are used as the second test sample, and the standard output value Stdout is corrected by the second test sample to calculate the secondary output value Stdout'.

[0038] Centered on the target number, select other numbers on both sides of it in sequence, with the number of selections being the same as the standard output value Stdout'. Then, perform another test on the test sample corresponding to the selected number and output the test results.

[0039] The beneficial effects of this invention are as follows: by ensuring the consistency of the assembly process and under the premise that damage to a single test sample will have a simultaneous impact on optical and electrical performance; to improve the testing efficiency of factory inspection and reduce equipment requirements; and by leveraging the correlation between adjacent products, to exempt some test samples from inspection, thereby improving testing efficiency. Attached Figure Description

[0040] The invention will now be further described with reference to the accompanying drawings.

[0041] Figure 1 This is a flowchart illustrating a method for detecting the factory condition of an optoelectronic composite cable according to the present invention. Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figure 1 As shown, this invention relates to a factory condition testing system and method for optoelectronic composite cables, comprising the following steps:

[0044] The optical fiber composite cable to be tested is divided into several testing batches, wherein the optical fiber composite cable in each testing batch is a product manufactured in the same production batch.

[0045] According to the preset sampling rules, several test samples are randomly selected from the same batch of tests and numbered; and after being divided into two test groups, optical power test and electrical performance test are performed respectively.

[0046] The test results of one of the test groups are taken as the first test sample, and the standard output value Stdout is calculated based on the number of "unqualified" test results in the first test sample. The calculation method is as follows:

[0047]

[0048] Where N represents the total number of samples in the first test sample, n represents the number of "non-compliant" samples in the first test sample, ΔX represents the number of other test results between any two adjacent "non-compliant" test results, and A represents the preset correction value, A≥0;

[0049] The calculated standard output value Stdout is rounded down, and the number information of the test sample with the "unqualified" test result is selected as the target number based on the first test sample. With the target number as the center, other numbers on both sides are selected in sequence, the number of selections is the same as the standard output value Stdout, and the test sample corresponding to the selected number is located in another test group.

[0050] The test results of the selected number corresponding to the test sample are used as the second test sample, and the standard output value Stdout is corrected by the second test sample to calculate the secondary output value Stdout'.

[0051] Reselect numbers centered on the target number, with the same number as the secondary output value Stdout', and perform another test on the test sample corresponding to the selected number, and output the test results;

[0052] Replace the test results from another test group with the first test sample and repeat the above process.

[0053] Based on the above content and the background technology of this invention, it can be seen that this application is a further improvement on the conventional group testing. For conventional group testing, if the number of cables to be tested is 100, each cable needs to be tested twice (optical power test and electrical performance test), and the total number of tests is 200. However, due to equipment limitations, the testing time varies for different types of cables, resulting in a long testing cycle and cumbersome operation. The innovation of this invention lies in simplifying the number of tests, that is, considering the consistency of assembly on the production line (assuming that the raw material cables and optical fibers are intact) and the correlation between adjacent products, so as to allow some cables to be exempted from testing.

[0054] In the specific scheme of this invention, firstly, a full inspection of a certain test is performed by the testing groups (Group 1 and Group 2). For example, all cables in Group 1 undergo optical power testing, and all cables in Group 2 undergo electrical performance testing. Then, the test results of Group 1 are used as the first test sample to calculate the standard output value Stdout and the secondary output value Stdout'. Using the "unqualified" samples in Group 1 as the standard, a specific number of cables with specific numbers are selected from Group 2 for optical power testing. Then, the test results of Group 2 are used as the first test sample again, and a specific number of cables with specific numbers are selected from Group 1 for electrical performance testing. Finally, the entire testing process is completed.

[0055] Secondly, it is worth noting the number selection process centered on the target number, which involves selecting numbers sequentially from both sides of the target number. For example, first select a number from the left side (smaller than the target number) that is closest to the target number and located in another detection group, then select a number from the right side (larger than the target number) that is closest to the target number and located in another detection group; then select from the left side - select from the right side - select from the left side - select from the right side - select from the right side, until the number of selected numbers meets the requirements; in the specific selection process, the order of right to left can also be adopted, which will not be elaborated here.

[0056] In a preferred embodiment of the present invention, the specific method for dividing the test samples of the same batch into two test groups is as follows:

[0057] The test samples are sorted according to the production completion time and numbered according to the sorting position, with the earlier the production completion time, the higher the sorting position.

[0058] The sorted test samples were stratified according to the number of test groups, and the test samples were divided into two groups by cross-selection.

[0059] The two groups of test samples are defined as test groups.

[0060] This embodiment describes how to divide the cable samples to be tested, i.e., the test samples, into two test groups. Considering the correlation between adjacent test samples, they are sorted before grouping, using the same sorting method as the production time (it should be noted that the test samples are all produced continuously on the same production line; cable products from different production lines are not considered to be from the same production batch). In the subsequent layering operation, because cable testing is divided into optical power testing and electrical performance testing, there are two layers (layer A and layer B). Different layers correspond to different test groups, and the distribution of different layers is cross-distributed, meaning that there is one layer B (layer A) between two adjacent layers A (layer B).

[0061] After determining the number of layers, it is also necessary to determine the number of samples in each layer. There are two ways to do this. One is to have the same number of samples in different layers. For example, in 20 samples, 1-5 belong to layer A, 6-10 belong to layer B, 11-15 belong to layer A, and 16-20 belong to layer B. The number of samples in each layer can be adjusted according to the total number of samples. This is existing technology and will not be elaborated here.

[0062] Another method is to calculate the number of samples in different layers when the number of samples in different layers is different. The applicable method is the detection time method, which is to calculate the number of samples based on the standard that the two detection groups complete the detection in the same time. For example, in a production detection environment, if the number of samples that complete the optical power test is x times the number of samples that complete the electrical performance test per unit time, then the number of samples in the optical power test layer is x times that of the other layer.

[0063] In another preferred embodiment of the present invention, in the first test sample, the order of the test results is the same as the order in the corresponding test group.

[0064] In another preferred embodiment of the present invention, during the process of selecting numbers on both sides with the target number as the center, when a certain number is selected by two or more target numbers, only one item is retained when generating the second test sample, and other identical items are deleted.

[0065] In another preferred embodiment of the present invention, the specific method for calculating the secondary output value Stdout' by correcting the standard output value Stdout using a second test sample is as follows:

[0066] Obtain the test results and standard output value Stdout from the second test sample;

[0067] The formula for calculating the secondary output value Stdout' is as follows:

[0068]

[0069] Where ΔS represents the number of test samples whose numbers correspond to any two adjacent "non-compliant" test results in the first test sample are located in another test group, n' represents the number of "non-compliant" samples in the second test sample, N' represents the total number of samples in the second test sample, and K represents the preset retention coefficient, where K < 1.

[0070] In another preferred embodiment of the invention, when the defect interval value If the value is greater than or equal to the standard output value Stdout, then all test samples from another test group are directly acquired for another test, and the test results are output.

[0071] In another preferred embodiment of the present invention, the method further includes obtaining all test results, and if any test sample is tested only once, then the other test is assumed to be qualified; if any test sample fails one of its tests, then the test sample is assumed to be unqualified.

[0072] A factory condition inspection system for an optical fiber composite cable, comprising:

[0073] Product segmentation module: Divides the optical fiber composite cable to be tested into several testing batches, wherein the optical fiber composite cable in each testing batch is a product manufactured in the same production batch;

[0074] According to the preset sampling rules, several test samples are randomly selected from the same batch of tests and numbered; and after being divided into two test groups, optical power test and electrical performance test are performed respectively.

[0075] First test module: Obtain the test results of one of the test groups as the first test sample, and calculate the standard output value Stdout based on the number of "unqualified" test results in the first test sample. The calculation method is as follows:

[0076]

[0077] Where N represents the total number of samples in the first test sample, n represents the number of "non-compliant" samples in the first test sample, ΔX represents the number of other test results between any two adjacent "non-compliant" test results, and A represents the preset correction value, A≥0;

[0078] The second testing module: rounds the calculated standard output value Stdout, and selects the number information of the test samples whose test results are "unqualified" based on the first test sample as the target number; with the target number as the center, other numbers on both sides are selected in sequence, the number of selections is the same as the standard output value Stdout, and the test samples corresponding to the selected numbers are located in another test group.

[0079] The test results of the selected number corresponding to the test sample are used as the second test sample, and the standard output value Stdout is corrected by the second test sample to calculate the secondary output value Stdout'.

[0080] Centered on the target number, select other numbers on both sides of it in sequence, with the number of selections being the same as the standard output value Stdout'. Then, perform another test on the test sample corresponding to the selected number and output the test results.

[0081] Assuming the raw materials are intact (optical fiber and copper power transmission wire in good condition), the main reason for substandard electrical performance or optical power in fiber-optic composite cables is errors in the assembly of the optical fiber and copper power transmission wire. In the assembly process of composite cables, optical fibers, copper wires, and filler ropes are placed together to form the cable core, which is then covered with material to create the final fiber-optic composite cable. Therefore, when the cable core is damaged, both the optical fiber and the copper power transmission wire are often affected.

[0082] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
