[0079] The following describes the preferred embodiments of the present invention with reference to the drawings. It should be understood that the preferred embodiments described herein are only for explaining and understanding the present invention and are not used to limit the present invention.

[0080] As shown in the Figure 1 drawings, an embodiment of the present invention provides a control system for an automated FCT turntable testing machine, including:

[0081] A test identification module: used to identify and analyze the test subject to determine the information to be tested;

[0082] A step matching module: used to match the test category according to the information to be tested, generate automatic test steps, and obtain step information;

[0083] An automatic turntable module: used to control the turntable transmission according to the step information and determine the turntable transmission data;

[0084] An FCT module: used to sequentially perform functional tests on the test subject according to the turntable transmission data and generate test results;

[0085] The working principle of the above technical solution is as follows: In the existing technical solution, when dealing with complex detection problems, the testing machine generally conducts combined testing through FCT and ICT. However, there are still great limitations in the functions that can be detected and the quantity of detections. Different from this, the above technical solution has a more comprehensive and effective solution to complex testing situations through the control system of the FCT turntable testing machine. First, the testing identification module identifies and analyzes the main body to be detected, obtains the information to be tested of the current main body, then the step matching module matches the information to be tested by category to generate steps. According to the steps, the turntable is automatically controlled to transfer the testing main body, and then tests are carried out in sequence according to the transfer order. Whenever it is transferred to a functional test point, the current functional test is carried out, and finally the test result is generated. When the above technical solution targets multiple testing main bodies, it optimizes the solutions for simultaneous detection and sorting detection, and improves the realization of the function of the control system of the automated FCT turntable testing machine around what main body to test, how to generate steps, and how to execute step operations;

[0086] The beneficial effects of the above technical solution are as follows: By performing step matching on the testing main body, the FCT testing efficiency is greatly improved, and at the same time, the processing effects for multiple testing main bodies and various testing situations are optimized.

[0087] In one embodiment, as shown in the appendix Figure 2 it is shown that the testing identification module includes:

[0088] The main body detection unit: used to obtain the testing main body information by detecting the testing main body; among them,

[0089] the testing main body information includes: the shape of the testing main body, the weight of the testing main body, and the state of the testing main body;

[0090] The identification and analysis unit: used to conduct identification and analysis according to the testing main body information to generate the information to be tested; among them,

[0091] the information to be tested includes: the serial number of the main body to be tested, the data of the main body to be tested, the to-be-tested state, the to-be-tested function, and the to-be-tested time.

[0092] The working principle of the above technical solution is as follows: The existing technology generally conducts single-item detection and does not need to conduct complex identification and analysis on the testing main body. As long as it passes a simple judgment and belongs to the preset conditions, the efficiency can be satisfied. This method is only applicable to simple tests and is dwarfed by complex tests; in the above technical solution, through the main body detection unit, the main body to be tested is detected, and the shape of the testing main body, the weight of the testing main body, and the state of the testing main body are detected. Then, through the analysis and identification unit, information collation and analysis are carried out according to the obtained detection information and the preset comparison database to generate the information to be tested;

[0093] The beneficial effects of the above technical solution are as follows: By identifying and analyzing the test subject, the information to be detected is obtained, which provides guarantee for subsequent solution processing and also enhances the rationality and accuracy of the test process.

[0094] In one embodiment, as shown in the appendix Figure 3 The step matching module includes:

[0095] Category matching unit: used to analyze the category to be tested of the subject to be tested according to the information to be tested, match the corresponding functional test according to the category to be tested, and generate matching information; where

[0096] The functional tests include: component test, signal test, load test, aging test, automatic switch control test, audio test;

[0097] Step generation unit: used to perform operation analysis according to the matching information and generate step information; where

[0098] The step information includes: step execution information, step operation time;

[0099] The working principle of the above technical solution is as follows: In the existing technical solutions, the test categories for subject testing are usually single categories or two to three categories, which have limitations in functional testing. In the above technical solution, the category matching unit analyzes the information to be tested and matches the corresponding functional tests, including component test, signal test, load test, aging test, automatic switch control test, audio test. Then, according to the matching information, corresponding steps are generated. For example, for an intelligent voice trash can that needs to perform automatic switch test and audio test, its test process needs to be analyzed according to the matching information to generate test steps.

[0100] The beneficial effects of the above technical solution are as follows: By judging the test category of the test subject, the test accuracy is greatly improved, and by generating test steps, the test efficiency of the test subject is improved.

[0101] In one embodiment, as shown in the appendix Figure 4 The automatic turntable module includes:

[0102] Instruction extraction unit: used to extract instructions according to the step information and generate control instructions; where

[0103] The control instructions include: test sorting instruction, test timing instruction, test instruction; where

[0104] The test instructions include: test start instruction, test end instruction, test interruption instruction;

[0105] Turntable control unit: used to perform turntable transfer control according to the control instruction and generate turntable transfer data; wherein,

[0106] The turntable transfer control includes: turntable rotation transfer control, turntable planar movement transfer control, and turntable lifting transfer control;

[0107] The working principle of the above technical solution is: by extracting the control instruction from the generated step information, determining the test sequence and test time, and then controlling the turntable according to the control instruction, transferring the test subject to the corresponding test point through the control of the turntable, and generating turntable transfer data during the transfer process;

[0108] The beneficial effect of the above technical solution is: by extracting the control instruction, effectively controlling the turntable, and improving the accuracy of the correspondence between the test subject and the test point.

[0109] In one embodiment, as shown in the appendix Figure 5 The FCT module includes:

[0110] Sequence unit: used to detect the test subject, analyze the test sequence of the test subject, obtain test sequence data, and judge it according to the turntable transfer data; wherein,

[0111] When the test sequence data meets the requirements of the turntable transfer data, it is the correct sequence;

[0112] When the test sequence data does not meet the requirements of the turntable transfer data, it is an abnormal sequence, and supplementary identification processing is performed;

[0113] FCT unit: used to perform functional tests in sequence according to the test sequence data, obtain functional test information, and generate test results; wherein,

[0114] The functional test information includes: test number, test data, and test time;

[0115] When all the functional test information is within the preset threshold range, the test is successfully passed;

[0116] When there is first abnormal data in the functional test information, the test is not passed, and abnormal detection data is generated; wherein,

[0117] The first abnormal data is information data that is not within the preset threshold range;

[0118] The working principle of the above technical solution is as follows: In the existing technical solution, the detection of FCT generally tests around a single test subject in sequence and cannot handle the situation of testing multiple test subjects. In the above technical solution, through the Shunwei unit, the test sequence of the test subjects is analyzed to obtain the test order of the test subjects. According to the different test orders of the test subjects, the order is carried out sequentially, and there are also cases of simultaneous testing. For example, when a product needs to be tested for signals and the audio test is idle at this time, and exactly another product needs to be tested for audio, then the two tests do not affect each other and can be carried out simultaneously. Among them, the test order of the test subjects also needs to be checked. If it does not meet the requirements, it needs to be identified and judged again. If two products have different functional test requirements and also have the same functional test requirements, at this time, it is necessary to analyze the start time of the same functional test of the two according to their different steps to obtain a sorting scheme, and conduct a functional test through the FCT unit, and finally generate an intuitive test result;

[0119] The beneficial effects of the above technical solution are as follows: Through sorting, the test efficiency is greatly improved. By judging the sorting, the test error rate is reduced and the test efficiency is improved.

[0120] In one embodiment, the step matching module further includes:

[0121] Multi-subject test unit: used to perform multi-element tests on multiple subjects to obtain a test data set of multiple subjects; among them,

[0122] The test data set includes: first test data, second test data;

[0123] The multi-element test includes the following steps:

[0124] Step S100: Sort the multiple subjects for testing to generate test numbers;

[0125] Step S200: According to the test numbers, sequentially perform test detections on multiple test subjects to obtain test detection information; among them,

[0126] The test detection information includes: subject status information, subject structure data, subject parameter information;

[0127] Step S300: According to the test detection information, conduct test scheme analysis to determine the first test strategy, and sequentially test the test subjects according to the first test strategy to obtain the first test data; among them,

[0128] The first test strategy includes the test schemes of a preset part among the multiple subjects;

[0129] Step S400: Detect the function occupancy of the testing machine based on the first testing strategy, obtain the function occupancy information, conduct occupancy analysis, generate the second testing strategy, and successively test the testing subject according to the second testing strategy to obtain the second test data;

[0130] The working principle of the above technical solution is as follows: By conducting multivariate tests on multiple subjects, obtain the test data sets of multiple testing subjects, sort the tests of multiple subjects to generate test serial numbers, and successively conduct test detections according to the serial numbers to detect the status information, structural data, and parameter information of the testing subjects. Analyze the test plan based on this information to generate the first testing strategy. The first testing strategy is for a part of the testing subjects divided according to a preset ratio among all the testing subjects to arrange the test steps. On the basis of the first testing strategy, conduct functional test analysis on the remaining untested testing subjects to generate the second testing strategy and conduct tests to obtain the second test data;

[0131] The beneficial effects of the above technical solution are as follows: By arranging the first and second testing strategies for multiple testing subjects, the testing accuracy and testing efficiency are improved.

[0134] The turntable monitoring data includes: turntable command monitoring data and turntable transmission control monitoring data;

[0135] The control and alarm unit: used to compare the turntable monitoring data with the turntable safety data in the preset turntable database, obtain the turntable deviation value, and make a judgment; where

[0136] When the turntable deviation value is within the preset threshold range, the turntable control is normal control;

[0137] When the turntable deviation value is not within the preset threshold range, the turntable control is abnormal control, and an abnormal control determination is made; where

[0138] The abnormal control determination includes: making a grading judgment according to the turntable deviation value and the preset deviation value grading data to obtain the abnormal level; where

[0139] The abnormal levels include: red abnormal level, yellow abnormal level, green abnormal level; where the red abnormal level is greater than the yellow abnormal level, and the yellow abnormal level is greater than the green abnormal level;

[0140] The working principle of the above technical solution is as follows: In the existing technical solution, a turntable is used to transfer the test subject, and when the transfer goes wrong, an emergency stop is carried out. There is a lack of advance prediction of error situations and solutions after errors, which is too simplistic. In the above technical solution, by monitoring the transmission control of the turntable, turntable monitoring data is obtained, and then the turntable monitoring data is compared with the turntable safety data in the preset turntable database to obtain the turntable deviation value. Then, it is judged whether there is a problem with the turntable control. When it is determined that there is a problem with the turntable control, an abnormal control determination is carried out, and its abnormal level is obtained.

[0141] The beneficial effects of the above technical solution are as follows: Through the abnormal level, the subjective awareness of abnormal situations is improved, and at the same time, by monitoring the turntable control, the test safety is improved.

[0152] Step S40: Compare the spatial offset angle of the turntable with the turntable safety data in the preset turntable database to judge its offset degree and classify abnormal situations;

[0154] The beneficial effect of the above technical solution is: By calculating the turntable offset from multiple angles, the accuracy of the turntable offset result is greatly improved. By the hypercomplex method, the calculation time is greatly saved and the calculation efficiency is improved.

[0160] The working principle of the above technical solution is: In the existing technical solution, the test subject is tested in a pipeline, lacking the judgment of the correctness of the test process; in the above technical solution, the generated steps are detected, the operation information is obtained by analyzing the generated automatic test steps, and the functional role is analyzed according to the operation information to analyze whether its functional role is suitable for the current test subject. If it is suitable, continue the test. If it is not suitable, perform preset emergency processing;
