[0020] Further, after determining that the product type and quantity are qualified, L 1 and M 1 If L 1 =M 1 , then it is determined to be qualified to enter the QR code scanning; if L 1 >M 1 , the position scanning device is used to scan the specific extra QR code product, and detect whether the extra QR codes on the product are consistent. If they are consistent, the product is judged as qualified and enters the QR code scanning. If they are inconsistent, the product is marked as a special product and the QR code is pasted again.

[0021] Furthermore, if L 1 <M 1 , the specific product without a QR code is scanned by the position scanning device, the product is marked and the QR code is re-affixed.

[0027] Furthermore, when I0 <2, I 1 <3, I 2 <5, I 3 <10, and at the same time satisfy (I 0 +I 1 +I 2 +I 3 ) / M 1 When ≤0.05, the entire batch of products is judged to be qualified.

[0028] Furthermore, after scanning the barcode, the scanned barcode information is transmitted to the PC terminal system for comparison of the scanned data between the system and B 1 -B N After the barcode of the class is matched, if the detected barcode is not in B 1 -B N When a barcode of the same type is found, the detected barcode information is transmitted to the barcode detection system for detection. The product is traced according to the production date, product model, internal hardware version number and product serial number recorded in the barcode, and the barcode itself is judged to be correct. If the barcode is wrong, the PC terminal system sends a command for the test instrument to continue scanning. If the barcode is correct, the product information and A 1 -A N The product information of major categories is compared and reclassified. If the classification is possible, the PC terminal system will issue a command to enter the product into the DUT test system for corresponding testing.

[0029] Furthermore, if classification is not possible but the barcode is correct, the product information is transmitted to the data storage system for storage, and the PC terminal system issues instructions to enter the product into the DUT test system for routine testing, and after the test, the product performance is compared with the standard performance to determine the specific DUT test method.

[0030] Furthermore, if the barcode is still wrong after the test instrument continues to scan, the PC terminal system will issue an instruction to send the product back to the production line for re-barcoding.

[0031] Furthermore, after the DUT test is performed on the product, the test information is transmitted to a remote data storage center to achieve remote monitoring of the product.

In addition, since the corresponding classification of the barcode and the product is set, the DUT test method of the product is classified and matched with the product and the barcode, so that after scanning the barcode, the product can be quickly classified for performance testing, thereby increasing the test efficiency. At the same time, the barcode inspection system is used to detect problems with the barcode itself to prevent incorrect testing processes.

[0034] Secondly, the present invention can help the high-frequency test system to maintain a standardized environment under high precision and high reliability requirements by real-time monitoring and quantitative evaluation of environmental factors, thereby ensuring the accuracy and consistency of the test results.

[0042]

[0043] The test instrument includes a scanner, which includes a gun handle and a scanning head. The scanning accuracy of the scanning head is 0.10mm. The scanning light source is visible laser with a wavelength of 650nm. The scanning speed is 98 times per second. The scanning width range is a minimum of 10mm and a maximum of 250mm. The scanning method is self-induction scanning. The PC terminal system is also equipped with a barcode detection system, a data storage system, and a scanning data comparison system. The DUT test system includes a product material detection system, a product cutting process detection system, a product welding process detection system, and a product design structure detection system. The switch box cuts off the opening and closing of the PC terminal system and the test instrument according to the alarm of the power supply system. Before testing, the PC terminal system is first started to detect the test environment. When it is detected that the test environment meets the standards, the PC terminal system is connected to the network and the classification information of the product to be tested and the DUT test information are transmitted to the data storage system of the PC terminal system for storage and analysis.

[0044] The PC terminal system obtains actual characteristic parameters and standard characteristic parameters of the test environment, and according to the actual characteristic parameters including multiple actual temperatures, multiple actual humidity, multiple actual noises and multiple actual vibrations, obtains a standard temperature and humidity interval, a standard noise interval and a standard vibration interval according to the standard characteristic parameters; the PC terminal system obtains a standard temperature and humidity mean according to the standard temperature and humidity interval, and obtains a temperature and humidity score according to the standard temperature and humidity mean and multiple actual temperatures and multiple actual humidity; the PC terminal system obtains a standard noise mean according to the standard noise interval, and obtains a noise score according to the standard noise mean and multiple actual noises; the PC terminal system obtains a standard vibration mean according to the standard vibration interval, and obtains a temperature and humidity score according to the standard vibration mean and multiple actual humidity. The vibration score is obtained by the actual vibration, and the PC terminal system calculates the comprehensive environment score according to the vibration score, the noise score and the temperature and humidity score, wherein the calculation formula is: Z(HP)=α*Z(DP)+β*Z(SP)+γ*W(SP); wherein Z(HP) represents the comprehensive environment score, α represents the weight of the vibration score, Z(DP) represents the vibration score, β represents the weight of the noise score, Z(SP) represents the noise score, γ represents the weight of the temperature and humidity score, and W(SP) represents the temperature and humidity score. The PC terminal system determines whether the comprehensive environment score is less than or greater than a preset score. If the comprehensive environment score is not less than the preset score, it is determined that the test environment meets the standard. If the comprehensive environment score is less than the preset score, it is determined that the test environment does not meet the standard.

[0045] The present invention obtains a plurality of actual temperatures, a plurality of actual humidity, a plurality of actual noises and a plurality of actual vibrations of the standard characteristic parameters and the actual characteristic parameters of the test environment, obtains a standard temperature and humidity interval, a standard noise interval and a standard vibration interval through the standard characteristic parameters, obtains a standard temperature and humidity mean through the standard temperature and humidity interval, obtains a temperature and humidity score through the standard temperature and humidity mean and a plurality of actual temperatures and a plurality of actual humidity, obtains a standard noise mean through the standard noise interval, obtains a noise score through the standard noise mean and a plurality of actual noises, obtains a standard vibration mean according to the standard vibration interval, obtains a vibration score through the standard vibration mean and a plurality of actual vibrations, calculates a comprehensive environment score through the vibration score, the noise score and the temperature and humidity score, and obtains By taking the standard characteristic parameters and comparing them with the actual measured values ​​of temperature, humidity, noise and vibration in the actual test environment, the degree of compliance of the environment can be quantitatively evaluated. In this way, whether the test environment meets the standards can be accurately judged through a scoring system (such as temperature and humidity scores, noise scores, and vibration scores), thereby avoiding the limitations of single data for environmental evaluation. By setting appropriate standards through standard temperature and humidity ranges, noise ranges, and vibration ranges, it can ensure that the evaluation results meet industrial standards and equipment requirements, and avoid test data errors or equipment damage caused by environmental changes. By combining the scores of the three environmental factors of temperature, humidity, noise, and vibration, a comprehensive environmental score is obtained. This method can provide a more comprehensive environmental condition. It does not only rely on the monitoring of a single factor, reducing the limitations of a single-dimensional evaluation. Environmental scoring can help quickly determine whether the current environment is suitable for testing, ensuring the reliability and accuracy of experimental results. The comprehensive score can be used as a basis for decision-making to further optimize the test environment. This method allows real-time monitoring and evaluation of the test environment through the PC terminal system, which means that when environmental parameters deviate from standard values, the system can automatically alarm or prompt the operator to make adjustments, discover problems in time, and avoid test errors or equipment damage caused by changes in environmental factors. The automated detection and scoring system can greatly improve test efficiency, reduce human judgment errors, and reduce the workload of manual monitoring. High-frequency testing usually has high requirements for the environment, temperature, humidity, and noise. External factors such as temperature and vibration may affect the accuracy of the test results. When the test environment is unstable or does not meet the standards, it may cause equipment errors or failures. This method can ensure that the environment is within the standard range, thereby improving the reliability and accuracy of the test. This method helps to standardize the management of the test environment. By systematically collecting and analyzing environmental parameters, the equipment operating environment can be regularly reviewed to ensure that all tests are carried out under standard environmental conditions, thereby ensuring the traceability and compliance of the test results. Standardized management of environmental parameters can also help with auditing and optimization, reducing the negative impact of environmental fluctuations on equipment performance and experimental results during the test. Therefore, this method can monitor and quantify environmental factors in real time.It helps high-frequency test systems to maintain a standardized environment under high precision and high reliability requirements, thereby ensuring the accuracy and consistency of test results. Through a systematic and comprehensive scoring method, it can improve test efficiency, reduce the uncertainty caused by environmental factors, and provide a scientific basis for environmental adjustment and optimization. This method can not only improve test quality, but also provide strong support for the automated and intelligent management of high-frequency test systems.

[0046] The PC terminal system obtains the upper and lower limits of the temperature and humidity in the standard temperature and humidity interval, and calculates the standard temperature and humidity mean through the upper and lower limits of the temperature and humidity. The PC terminal system calculates the actual temperature and humidity through multiple actual temperatures and actual humidity, wherein the calculation formula is: Where S(WS) represents the actual temperature and humidity, n represents the number of actual temperatures, k represents the sequence number of the actual temperature, and S(WD) k represents the kth actual temperature, S(SD) k represents the kth actual temperature. The PC terminal system calculates the temperature and humidity score through the actual temperature and humidity, the standard temperature and humidity average, the temperature and humidity upper limit, and the temperature and humidity lower limit. The calculation formula is: Among them, W(SP) represents the temperature and humidity score, W(DS) represents the upper limit of temperature and humidity, W(DX) represents the lower limit of temperature and humidity, S(WS) represents the actual temperature and humidity, and B(WS) represents the standard temperature and humidity mean.

[0047] The present invention calculates the standard temperature and humidity mean through the temperature and humidity upper limit and temperature and humidity lower limit of the standard temperature and humidity interval, calculates the actual temperature and humidity through multiple actual temperatures and actual humidity, and calculates the temperature and humidity score through the actual temperature and humidity, the standard temperature and humidity mean, the temperature and humidity upper limit and the temperature and humidity lower limit. By calculating the standard temperature and humidity mean (based on the upper and lower limits) and the actually measured temperature and humidity, it is possible to objectively measure whether the test environment meets the standard requirements. This method not only relies on the standard setting, but also evaluates the environment through actual data, thereby avoiding the deviation caused by human judgment. High-frequency testing usually has stricter requirements on the test environment. For example, changes in temperature and humidity may affect the accuracy and repeatability of the test results. Real-time monitoring is performed through the PC terminal system, and temperature and humidity information can be obtained instantly and compared with the standard to ensure the stability of the test environment throughout the test process. If it exceeds the standard range, timely measures can be taken to adjust the environmental conditions. The temperature and humidity scoring system makes the detection process more automated. Through preset standards and scoring mechanisms, the system can quickly give the compliance score of the test environment without manual intervention. The scoring system can also help users more clearly understand whether the temperature and humidity are within the allowable range, so as to make corresponding adjustments. Using the PC terminal system to collect and process temperature and humidity data can more efficiently perform data analysis and automatically generate reports. This is especially important for high-frequency test systems, because environmental changes may have a greater impact on test results. Automatically generated reports can quickly reflect whether the environment meets the standards, which is convenient for traceability and recording. By comparing the actual temperature and humidity with the standard temperature and humidity average, the temperature and humidity score can reveal environmental deviations and help testers The test personnel optimize the test conditions. If the score is low, it means that the environment deviates far from the standard. The test personnel can improve the test environment by adjusting the temperature and humidity to ensure the validity of the test results. The long-term monitoring and scoring of temperature and humidity by the PC system can provide traceable data for future audits and quality management, which is of great significance for the verification of the test system, compliance checks and data archiving. Therefore, through the combination of standard temperature and humidity ranges, actual measured temperature and humidity, and temperature and humidity scores, the PC terminal system can accurately and real-time monitor and evaluate the test environment. The biggest advantage of this method is that it realizes automated and accurate environmental monitoring to ensure that the test is carried out under standard conditions, thereby improving the accuracy and reliability of the test results, reducing human errors, optimizing the test process, and improving test efficiency.

[0052] After determining that the product type and quantity are qualified, test L 1 and M 1 If L 1 =M 1 , then it is determined to be qualified to enter the QR code scanning; if L 1 >M 1 , the position scanning device is used to scan the specific extra QR code product, and detect whether the extra QR codes on the product are consistent. If they are consistent, the product is judged as qualified and enters the QR code scanning. If they are inconsistent, the product is marked as a special product and the QR code is pasted again.

[0053] If L 1 <M 1 , the specific product without a QR code is scanned by the position scanning device, the product is marked and the QR code is re-affixed.

[0054] If you find that L 1 =M 1 However, if there are still products with multiple QR codes or no QR codes, continue with the above operations.

[0055] After completing the environmental test and information storage, the barcode of the product is scanned with the test device. After scanning the barcode, the scanned barcode information is transmitted to the PC terminal system to compare the scanned data between the system and B 1 -B N If the barcode type is matched, the next step is to match the detected barcode type with A. 1 -A N The major product types are matched, and after matching, the PC terminal system transmits the DUT test method corresponding to the determined type of product to the DUT test system for testing.

Different major categories of products have different specific gravity requirements and methods. The qualification of the inspection results is determined based on the corresponding DUT test method data.

[0057] The DUT test method is to 1 -A NAfter testing the products of the major categories, the qualified materials of the tested products are those whose test values ​​of the materials are greater than the standard value of the test specific gravity λ 0 The qualified cutting of products means that the cutting process test value of the products is greater than the standard value of cutting ratio Z 0 The qualified welding process of the product means that the test value of the welding process of the product is greater than the standard value of the welding process 0 The qualified product design structure means that the test value of the product design structure is greater than the standard value of the design structure γ 0 .

[0058] Setting 0 >λ 0 >Z 0 >γ 0 , and detected A 1 -A N The welding process test value of major categories of products is less than P 0 The number is I 0 , detected A 1 -A N The material test value of most products is less than λ 0 The number is I 1 , detected A 1 -A N The cutting test value of the large category of products is less than Z 0 The number is I 2 , the product design structure detection value is detected to be less than γ 0 The number is I 3 .

[0059] When I 0 <2, I 1 <3, I 2 <5, I 3 <10, and at the same time satisfy (I 0 +I 1 +I 2 +I 3 ) / M 1 When ≤0.05, the entire batch of products is judged to be qualified.

[0060] After scanning the barcode, the scanned barcode information is transmitted to the PC terminal system for comparison of the scanned data between the system and B 1 -B N After the barcode of the class is matched, if the detected barcode is not in B 1 -B NWhen a barcode of the same type is found, the detected barcode information is transmitted to the barcode detection system for detection. The product is traced according to the production date, product model, internal hardware version number and product serial number recorded in the barcode, and the barcode itself is judged to be correct. If the barcode is wrong, the PC terminal system sends a command for the test instrument to continue scanning. If the barcode is correct, the product information and A 1 -A N The product information of major categories is compared and reclassified. If the classification is possible, the PC terminal system will issue a command to enter the product into the DUT test system for corresponding testing.

[0061] If classification is not possible but the barcode is correct, the product information is transmitted to the data storage system for storage, and the PC terminal system issues instructions to enter the product into the DUT test system for routine testing. After the test, the product performance is compared with the standard performance to determine the specific DUT test method.

[0062] If the barcode is still wrong after the test instrument continues to scan, the PC terminal system will issue a command to send the product back to the production line to re-label the barcode.

[0063] After DUT testing of the product, the test information is transmitted to the remote data storage center to achieve remote monitoring of the product.
