Description

Technical Field

[0001] The invention relates to the technical field of finished product testing of a rolling shutter door controller production line, and in particular to a finished product testing method for a fireproof rolling shutter door controller production line. Background Art

[0002] As an important part of fire safety equipment, the stability and reliability of the performance of fire shutter door controllers are directly related to the fire safety of buildings. In the production process of fire shutter door controllers, finished product testing is a key link to ensure product quality.

[0003] Among them, the test of fire shutter doors is mostly started remotely by the control center, and then the designated shutter door is tested to see if it is started. During on-site inspection, the three control methods of manual control, automatic control and mechanical control of the fire shutter door are usually tested. Specifically, for manual control, there are manual control buttons on both sides of the fire shutter door. Manual control is performed to check whether the shutter door is in normal operation. For automatic control, after the two independent fire detectors are activated, the temperature detector will alarm, and the shutter door controller should emit a fast-changing and slow-tuning sound to check whether the shutter door is in normal operation. For the mechanical control function, there is a chain in the on-site shutter engine to see whether it can be raised and lowered manually. Pay attention to check whether the chain is rusty and clamped at the same time, and check whether it is tight when closed.

[0004] However, the above-mentioned detection test is the same as most existing test methods, which only stays at the test of the control switch and closing tightness and internal structure of the fire shutter door. As far as the fire shutter door is concerned, the fire environment in which it is located is also a very important link, and the existing test methods often only consider some key parameters, while ignoring other factors affecting the performance, and cannot truly simulate the temperature changes and material strength changes under fire conditions, resulting in deviations between the test results and the actual situation. In addition, the existing test methods often only focus on the results of a single test, while ignoring the continuous impact of the fire situation on the material strength, that is, the cyclic impact.

[0044] If during the cycle calculation process, the final strength test value QL3 continues to be lower than the final strength test average value QL 3avg, it reflects that the current test strength tension state is not ideal, and the performance of the material under fire conditions will be affected.

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] This finished product testing method for fireproof rolling door controller production line is different from the existing testing methods. The existing testing methods often only consider some key parameters and ignore other factors that affect the performance. They cannot truly simulate the temperature changes and material strength changes under fire conditions, and also ignore the continuous impact of fire conditions on material strength. This algorithm unit improves the scientificity and accuracy of the test, and also optimizes and innovates the existing technology by simulating fire conditions and introducing other influencing parameters and concepts, providing a strong guarantee for the quality control and safety performance of fireproof rolling door controllers.

[0061] For example, see Figures 1 to 4 This implementation provides a finished product testing method for a fire shutter door controller production line. The specific test steps are as follows:

[0062] Step 1: Use the test acquisition module and cooperate with the control module to use the method of simulating a non-fire environment and a fire environment to test the rolling shutter door and collect test data;

[0063] Step 2: Based on the test data and using the test data evaluation processing module, the basic strength test value QL1, the comprehensive strength test value QL2 under the influence of fire, and the final strength test value QL3 are calculated and output in sequence;

[0064] Step 3: Based on the result of the final strength test value QL3, the test data evaluation processing module is used to evaluate and analyze the test results;

[0065] The test data include applied tension ZL, maximum applied tension ZL max , cross-sectional area YM, initial temperature W1, temperature after change W2, initial length of material L1, length of material after temperature change L2;

[0066] The test data evaluation and processing module includes a preliminary performance evaluation unit without fire influence, a unit for comprehensively considering the influence of fire on performance, and a final strength evaluation unit under cyclic influence;

[0067] The equipment used in the control module includes rolling door controller and fire environment simulation equipment;

[0068] The equipment used in the test acquisition module includes tension tester, temperature sensor, length and area measuring equipment;

[0069] The equipment used in the test data evaluation and processing module includes data recording and analysis equipment.

[0070] In this embodiment, the system forms a complete performance evaluation system through the cooperation of three algorithm units. Combining the three operation results of QL1, QL2 and QL3, QL1 is the basic strength test value. The algorithm unit is used to determine the basic strength test value of the fire shutter door controller in the initial state, that is, when it is not affected by the fire, so as to provide a preliminary performance evaluation and provide a basis for subsequent detailed calculations. QL2 is the comprehensive strength test value under the influence of fire. This value can more comprehensively consider the complex impact of fire on material strength. Among them, the thermal expansion coefficient P reflects the rate of change of the length of the material when the temperature changes, which is used to evaluate the thermal stability of the material. QL3 is an important indicator of the performance of fire and thermal stress, and the final strength test value is QL3. Based on QL2, this value further considers the continuous influence of the fire situation on the material strength, so as to provide a more comprehensive and accurate performance evaluation. The calculation result of QL3 can also make corresponding adjustments to the strength reduction factor D to observe the cyclic feedback purpose of continuous testing. As a result, the adjustment of the strength reduction factor D affects the calculation feedback to QL1 and QL2, so that the three algorithms of this system each have unique beneficial effects. The cyclic influence of QL3 on QL1 provides a scientific, comprehensive and practical method for the finished product testing of the fire shutter door controller production line.

[0071] See also Figures 1 to 4 , the calculation formula for the preliminary performance evaluation unit without fire impact is as follows:

[0072] QL1=Q0×(1-D)+ZL;

[0073] Q0=ZL max / YM;

[0074] in:

[0075] QL1 is the basic strength test value;

[0076] Q0 is the initial strength of the material, and Q0 reflects the initial strength of the rolling door samples in the same batch tested and calculated;

[0077] D is the strength reduction factor, which reflects the degree of strength reduction caused by temperature;

[0078] ZL is the applied tension;

[0079] ZL max is the maximum applied tension, ZL max Reflects the maximum tension applied to the rolling door specimen before it breaks;

[0080] YM is the cross-sectional area, YM is the original cross-sectional area of ​​the rolling door specimen.

[0081] In this embodiment: First, the calculation part of "Q0×(1-D)" in this algorithm unit is intended to determine the basic strength of the material after considering the temperature effect under fire conditions, where QQ0 is the initial strength of the material, and D is the strength reduction factor. By subtracting the strength reduced due to the temperature effect from the initial strength, a more practical material strength value under fire conditions is obtained. The result of this calculation part is the core of the preliminary performance evaluation unit without the influence of fire. It provides a basic evaluation of the material strength under fire conditions. This result will serve as the basis for subsequent calculations, and the applied tension ZL is added to the above calculation results to consider the strengthening effect of tension on the material strength. In practical applications, tension increases the strength of the material by increasing its internal stress. Therefore, by adding the applied tension ZL, a comprehensive strength value that takes into account both the temperature effect and the tension enhancement can be obtained, that is, the basic strength test value QL1 without the influence of fire.

[0082] Through the preliminary performance evaluation unit without fire influence, this algorithm can clearly see how the initial strength Q0 of the material, the applied tension ZL and the strength reduction factor D affected by the temperature under fire conditions work together on the basic strength test value QL1. This provides a scientific basis for optimizing material selection, adjusting tension and predicting performance under fire conditions during the production process.

[0083] The strength reduction factor D parameter in the preliminary performance evaluation unit without the influence of fire enables the controller to simulate the influence of temperature on material strength under different fire conditions, which helps to more accurately evaluate the risk level of the fire shutter door controller in a fire and provide strong guarantee for the safety performance of the product;

[0084] Through the calculation of the preliminary performance evaluation unit without the influence of fire, the strength and tension test values ​​of different batches of products can be quickly obtained, so as to timely discover abnormalities in the production process, optimize the production process, and improve product quality and production efficiency.

[0085] See also Figures 1 to 4 , the calculation formula for the unit that fully considers the impact of fire on performance is as follows:

[0086]

[0087] in:

[0088] QL2 is the comprehensive strength test value under the influence of fire;

[0089] P is the thermal expansion coefficient of the material, which reflects the relative change in length of the material when the temperature changes;

[0090] The calculation formula of the material thermal expansion coefficient P is as follows:

[0091] P = (W2-W1) / [L1×(L2-L1)];

[0092] W2 is the temperature after the change;

[0093] W1 is the initial temperature;

[0094] W2-W1 reflects the change in temperature;

[0095] L1 is the initial length of the material;

[0096] L2 is the length of the material after temperature change;

[0097] L2-L1 reflects the change in material length after temperature changes.

[0098] In this embodiment, first, "(P×ZL) 2 "The calculation part takes into account the combined effects of the material thermal expansion coefficient P and the applied tension ZL on the material strength. The material thermal expansion coefficient P reflects the expansion degree of the material under temperature changes, and the applied tension ZL affects the strength of the material by increasing the internal stress. The thermal expansion coefficient P of the material and the applied tension ZL are multiplied and squared to obtain a quantity representing the combined effects of thermal expansion and tension. This calculation result will be used together with other items to calculate the comprehensive strength test value QL2 under the influence of fire for the unit that fully considers the influence of fire on performance, so as to obtain a more comprehensive material strength value that considers the influence of fire;

[0099] This calculation expression combines the basic strength test value QL1 of the preliminary performance evaluation unit without fire influence, the combined effect of thermal expansion and tension, and a certain combined effect of the initial strength Q0 of the material and the applied tension ZL. By adding these terms and subtracting a combined effect term, we get a comprehensive strength value that takes both the basic strength and the fire influence into account. This calculation result is the core of the unit that fully considers the impact of fire on performance. It provides a more comprehensive material strength assessment that takes both the basic strength and the fire influence into account.

[0100] After the thermal expansion coefficient P of the material is introduced into this algorithm unit, the unit that fully considers the impact of fire on performance can more accurately evaluate the strength change of the material under fire conditions, which helps to more accurately understand the actual performance of the fire shutter door controller in a fire and provide data support for product design and improvement;

[0101] Comprehensive consideration of the impact of fire on performance The unit comprehensively considers factors such as the initial strength, tension, temperature impact and thermal expansion coefficient of the material to form a complete evaluation system, which helps to more comprehensively understand the performance characteristics of the fire shutter door controller and provide guidance for product selection and use;

[0102] By comprehensively considering the impact of fire on performance, the performance of fire shutter door controllers under different fire conditions can be predicted. This prediction not only helps to evaluate the safety performance of the product, but also provides strong support for product marketing and customer service;

[0103] It is worth noting that the material thermal expansion coefficient P is specifically the linear thermal expansion coefficient, which mainly focuses on the change in length of the material when the temperature changes. For structural parts such as fire-resistant rolling shutter doors, changes in length will directly affect their dimensional stability and functionality. Therefore, if the test mainly focuses on dimensional stability and needs to evaluate the impact of temperature changes on the rolling shutter door structure, the linear thermal expansion coefficient is more applicable.

[0104] See also Figures 1 to 4 , the calculation formula of the final strength evaluation unit under cyclic impact is as follows:

[0105]

[0106] in:

[0107] QL3 is the final strength test value.

[0108] In this embodiment, the algorithm unit first The calculation part is designed to take into account the continuous impact of fire conditions on material strength. The comprehensive strength test value QL2 under the influence of fire is the result of the unit that fully considers the impact of fire on performance, indicating the comprehensive strength considering the impact of fire. Q0 is the initial strength of the material, and P is the thermal expansion coefficient of the material. By combining these parameters, a quantity representing the strength increase / decrease under cyclic influence can be obtained. This calculation result is a key part of the final strength evaluation unit under cyclic influence, which is used to calculate the final strength test value QL3 under cyclic influence.

[0109] The calculation part calculates the strength change caused by the difference between the comprehensive strength test value QL2 under full consideration of the fire influence and the basic strength test value QL1 without the fire influence under the cyclic influence, wherein, by calculating this difference and multiplying it by the strength reduction factor D, a quantity representing the strength change caused by the cyclic influence can be obtained;

[0110] The final strength evaluation unit under cyclic influence of this algorithm realizes the cyclic evaluation of the performance of the fire shutter door controller by substituting the comprehensive strength test value QL2 under the fire influence of the unit that fully considers the impact of fire on performance. This evaluation not only considers the impact of a single fire, but also considers the continuous impact of multiple fires on the strength of the material, thereby revealing the performance characteristics of the product in more depth.

[0111] Through the calculation results of the final strength evaluation unit under cyclic influence, the performance change trend of the fire shutter door controller after multiple fires can be discovered, which provides valuable guidance information for product design and improvement, and helps to continuously improve the safety performance and reliability of the product.

[0112] See also Figures 1 to 4 , the test analysis based on the final strength test value QL3 is as follows:

[0113] If during the cycle calculation process, the final strength test value QL3 continues to be higher than the final strength test average value QL 3avg , it reflects that the current test strength tension state is ideal, the material has high fire resistance and high stability, and there is no need for continuous testing and observation;

[0114] If during the cycle calculation process, the final strength test value QL3 continues to be lower than the final strength test average value QL 3avg , it reflects that the current test strength tension state is not ideal, and the performance of the material under fire conditions will be affected. The strength reduction factor D should be adjusted to observe the degree of influence. The specific adjustment formula of the strength reduction factor D is as follows:

[0115] D new =D×[1+(QL3-QL2) / QL2];

[0116] D new is the adjusted intensity reduction factor, and the adjusted intensity reduction factor D new Introduced into the next cycle calculation, that is, as a replacement input value for the strength reduction factor D in the preliminary performance evaluation unit without fire influence.

[0117] In this embodiment, the final strength evaluation unit under the cyclic influence of this algorithm unit plays a vital role in the strength and tension test system of the fire shutter door controller. It not only considers the direct impact of fire on material strength, but also simulates the continuous impact of fire conditions on material strength, and adjusts the strength reduction factor D in the preliminary performance evaluation unit without the influence of fire accordingly, thereby realizing the cyclic influence of the preliminary performance evaluation unit without the influence of fire. The final strength evaluation unit under the cyclic influence can more accurately reflect the continuous weakening effect of fire on material strength through the cyclic influence mechanism. This effect is particularly obvious after multiple fires, and the traditional single evaluation method often cannot capture this point. Therefore, the use of the final strength evaluation unit under the cyclic influence can significantly improve the accuracy of the evaluation and provide more reliable data support for the design and improvement of the fire shutter door controller.

[0118] Specifically, the final strength test value QL3 of the current test is higher than the final strength test average value QL 3avg, indicating that under the current test conditions, the performance of the material is stable and better than the previous average level. From the final strength evaluation unit under the influence of cycles, it can be seen that the larger final strength test value QL3 is due to the larger value of the comprehensive strength test value QL2 under the influence of fire, that is, the basic strength test value QL1 and the better thermal expansion effect. Further analysis shows that if the comprehensive strength test value QL2 under the influence of fire is larger, then according to the comprehensive consideration of the fire on performance unit, it is due to the larger basic strength test value QL1, that is, the initial strength Q0 of the material and the smaller temperature effect.

[0119] The final strength test value QL3 is lower than the final strength test average value QL 3avg , indicating that the performance of the material under the current test conditions is not as good as the previous average level, and there are problems that need to be solved. By analyzing the reasons for the small final strength test value QL3, it can guide the subsequent material improvement iteration work. From the final strength evaluation unit under the influence of the cycle, it can be seen that the small final strength test value QL3 is due to the small value of the comprehensive strength test value QL2 under the influence of the fire. If the comprehensive strength test value QL2 under the influence of the fire is small, then according to the comprehensive consideration of the fire on the performance unit, it is due to the small basic strength test value QL1, that is, the initial strength Q0 of the material is low, the temperature has a large impact, and the material thermal expansion coefficient P has a negative impact on the performance. If the material thermal expansion coefficient P is large, it means that the fire has a continuous impact on the material, and it is necessary to strengthen fire prevention measures and change the material formula to improve the fire resistance.

[0120] In summary, comparison with the average value of the previous final strength test value QL3 can evaluate the stability and consistency of the current test results, and guide subsequent material improvement iterations by analyzing the reasons for being too large or too small. This comparison method helps ensure that the performance of the material under fire conditions meets the design requirements.

[0121] For example 2, please refer to Figures 1 to 4 , the final strength test average QL 3avg The calculation formula is as follows:

[0122] QL 3avg =(QL 3,1 +QL 3,2 +QL 3,3 +......+QL 3,n ) / n;

[0123] n is the total number of rolling shutter door tests, reflecting the total number of rolling shutter doors in the same batch that have been tested and have reached the ideal state;

[0124] QL 3,1 is the first final strength test value, QL 3,2 is the second final strength test value, QL3,3 is the third final strength test value, QL 3,n is the nth final strength test value.

[0125] In this embodiment, first, the accuracy and reliability of the test are improved.

[0126] Stability Assessment:

[0127] By comparing the final strength test value QL3 of the current test with the average value of the final strength test values ​​QL3 of the previous tests, the stability of the test results can be intuitively evaluated. If the final strength test value QL3 of the current test is not much different from the average value, it means that the test results are relatively stable and have a high degree of credibility. On the contrary, if the difference is large, it is necessary to further check whether there are abnormalities in the test process and equipment. In multiple tests, if the final strength test value QL3 always fluctuates within a relatively stable range, then it can be considered that the test method has good consistency. This consistency check helps to ensure the reliability and comparability of the test results, and provides a solid foundation for subsequent data analysis and product improvement.

[0128] By comparing the final strength test value QL3 of the current test with the final strength test average value QL 3avg , it is possible to discover the changing trend of product performance. If the final strength test value QL3 continues to improve, it means that the product performance is constantly being optimized. If the final strength test value QL3 decreases, it is necessary to adjust the design and production process of the product to improve its performance. On the production line, by continuously monitoring and comparing the final strength test value QL3, it is possible to promptly discover abnormal conditions in the production process, which helps to take timely corrective measures to ensure the consistency and stability of product quality. If the final strength test value QL3 of the current test is much lower than the average value, it means that there is a greater risk of strength and tension performance of the product under fire conditions. At this time, it is necessary to deeply analyze the reasons and take corresponding measures to improve them to reduce the safety risks of the product.

[0129] By comparing the final strength test value QL3 under different test conditions, the effectiveness and feasibility of the new technology can be verified;

[0130] In summary, using the final strength test average QL 3avg The comparison method has significant beneficial effects in the test and evaluation of fire shutter door controllers. It not only helps to improve the accuracy and reliability of the test, but also provides useful guidance for product design and improvement, and promotes technological innovation and continuous improvement. Therefore, in practical applications, full attention should be paid to the application and promotion of this comparison method.
