The step of screening the first historical usage data refers to screening life end cases with failure reasons of poor fire resistance from the first historical usage data, and obtaining historical records of all cases, namely the first target usage data. By finding out the historical data of bus duct failure caused by poor fire resistance from the historical use conditions, the technical effects of providing a data base and a data support for the subsequent preliminary analysis and estimation of the fire resistance performance based on the bus duct historical use conditions and providing reference data for the subsequent evaluation of the fire resistance of the bus duct are achieved.

Step S200: comparing the first target use data to obtain a first fire resistance pre-evaluation, wherein the first fire resistance pre-evaluation refers to preliminary evaluation of fire resistance performance of the first bus duct;

specifically, the comparison of the first target usage data refers to comparing and analyzing the historical usage situation of the first bus duct to obtain the temperature situation when the first target fails, the correlation degree of failure reasons and temperature, fire resistance time and the like, and the first fire resistance pre-evaluation is performed on the first bus duct according to the obtained information. The first fire resistance pre-evaluation is based on historical data of historical use conditions, including the highest fire resistance temperature, fire resistance duration and the like, of the fire resistance condition of the first bus duct, so that preliminary evaluation is obtained. Preferably, based on a plurality of bus duct failure cases caused by insufficient fire resistance, the temperature of the bus duct failure in each case and the working time under the corresponding temperature are respectively extracted, and the record with the highest temperature and the longest working time is taken as the preliminary evaluation of the bus duct. Through carrying out fire-resistant pre-evaluation to first bus duct, can realize making the bedding for confirming the temperature range that carries out the temperature test subsequently, reduce detection operation, reduce detection cost's technical effect.

Step S300: collecting first basic information of the first bus duct, wherein the first basic information comprises a first fire resistance requirement;

specifically, the first basic information of the first bus duct includes: production batch, production process, production model, ceramic proportion of composite material, composite mode, service time in fire environment, temperature bearable in fire, etc. The first fire resistance requirement refers to a fire resistance temperature value, which refers to the highest temperature that can be tolerated in a fire environment, and a fire resistance duration, which refers to the maximum time that line integrity can be maintained in a fire environment. Based on the first basic information, the technical effect of providing basic data for subsequent fire-resistant treatment of the first bus duct is achieved.

Step S400: determining a first process condition based on the first refractory requirement and the first refractory pre-evaluation, wherein the first process condition comprises a first process temperature threshold;

In particular, from obtaining the first fire resistance requirement and the first fire resistance pre-evaluation, a first process condition for measuring a fire resistance performance test of the first bus duct may be determined. The first treatment condition refers to a specific test condition in the fire resistance test of the first bus duct, and comprises a test temperature condition, a test duration time and the like. The first treatment temperature threshold refers to a treatment temperature interval for the first bus duct, i.e. a temperature range in a fire resistance performance test, obtained according to the first fire resistance requirement and the first fire resistance pre-evaluation. Wherein the first refractory requirement is taken as the lowest test temperature, namely the lower limit of a first treatment temperature threshold value, and the highest temperature evaluation in the first refractory pre-evaluation is taken as the highest test temperature, namely the upper limit of the first treatment temperature threshold value. Therefore, the temperature range of the test can be accurately determined, the test amount is effectively reduced, the test time is shortened, the test efficiency is improved, and the technical effect of evaluating the fire resistance performance of the first bus duct is improved.

Step S500: generating a first treatment scheme by using a control variable method according to the first treatment temperature threshold, wherein the first treatment scheme comprises a first constant temperature scheme and a first variable temperature scheme;

Specifically, the first treatment regimen is generated by a controlled variable method based on the obtained test temperature range. Since there are many variables characterizing the first bus duct, it is necessary to analyze and evaluate factors mainly affecting the fire resistance of the first bus duct by controlling the variable method. The first treatment scheme refers to that the first bus duct is subjected to test treatment by controlling other variables, optionally, wind speed, air pressure, humidity and the like, and only changing the temperature. The first constant temperature scheme is to adjust the test temperature to a fixed value, and test the first bus duct by adopting different fixed temperatures for a plurality of times. The first temperature changing scheme is to set a temperature interval, and test the first bus duct by carrying out random change of temperature in the temperature interval. Therefore, the fire resistance of the first bus duct can be further tested by controlling the temperature parameter, and the technical effect of improving the accuracy of the fire resistance test of the bus duct is achieved.

Step S600: performing constant temperature treatment on the first bus duct according to the first constant temperature scheme to obtain a first treatment result, and performing variable temperature treatment on the first bus duct according to the first variable temperature scheme to obtain a second treatment result;

Thereby, the technical effect of providing basic analysis data for subsequent failure inspection and analysis is achieved.

Step S700: sequentially performing failure inspection and analysis on the first processing result and the second processing result to obtain a first analysis result and a second analysis result respectively;

specifically, the sequentially performing failure inspection and analysis on the first processing result and the second processing result refers to a relevant parameter characterizing the performance of the first bus duct in the inspection processing result, and preferably, the relevant parameter may be: appearance parameters of the bus duct, temperature rise condition parameters of the bus duct shell, temperature rise condition parameters of the surface of the insulating piece in the duct and the like. And judging whether the first bus duct fails by checking whether the conductive function of the first bus duct is good or not and whether the circuit integrity can be maintained in a flame state in a certain time. The first analysis results are the highest temperature that the bus duct can withstand at a constant temperature, and the longest operating time that can be sustained at each high temperature. The second analysis result is the highest temperature change interval which can be born by the bus duct in a temperature change state and the longest working time which can be sustained in each temperature change interval. This achieves the technical effect of providing reliable test data for the subsequent evaluation of the fire resistance of the first bus duct.

Step S800: and generating a first fire resistance evaluation of the first bus duct according to the first analysis result and the second analysis result.

Specifically, the fire resistance condition of the first bus duct under the condition of variable temperature and constant temperature is analyzed by analyzing the information related to the fire resistance performance of the first bus duct in the first analysis result and the second analysis result, and optionally, fire resistance time, fire resistance temperature and the like. The method has the advantages of realizing stable and comprehensive evaluation of the fire resistance of the ceramic matrix composite bus duct, being strong in operability, reducing detection cost, and improving the detection efficiency and accuracy by improving the intelligent degree of fire resistance detection.

Further, as shown in fig. 2, in the generating the first processing scheme according to the first processing temperature threshold by using the control variable method, step S500 of the embodiment of the present application further includes:

step S510: gradient division is carried out on the first processing temperature threshold value, and first division results are respectively obtained, wherein the first division results comprise a plurality of temperature intervals;

Step S530: and respectively designing a plurality of constant temperature tests according to the average temperatures, wherein the constant temperature tests form the first constant temperature scheme.

Specifically, after the first processing temperature threshold is obtained, dividing the temperature interval according to a gradient to obtain the first division result. The first division result includes a plurality of temperature intervals. And the average temperature is calculated for each temperature interval, and the average value can be obtained because the degree of influence on the fire resistance of the first bus duct in each temperature interval is not great, so that the test times are reduced, the test efficiency is improved, and the test cost is reduced. And then respectively designing a plurality of constant temperature tests according to the plurality of average temperatures, and forming the first constant temperature scheme by the plurality of constant temperature tests, wherein the plurality of average temperatures and the plurality of temperature intervals are in one-to-one correspondence. Therefore, the technical scheme of testing the fire resistance of the first bus duct at the constant temperature is realized, and a foundation is laid for the subsequent evaluation of the fire resistance of the first bus duct.

The first processing temperature threshold is 800-1050 ℃, and the first processing temperature threshold is divided according to the condition that the fire resistance of the first bus duct in different temperature nodes changes, wherein the nodes are: 850 ℃, 900 ℃, 1050 ℃. The divided temperature ranges are 800-850 ℃, 850-900 ℃, 900-1000 ℃, 1000-1050 ℃, and the average value is respectively taken according to the four temperature ranges, and the obtained temperatures corresponding to the four constant temperature tests are as follows: 825 deg.c, 875 deg.c, 950 deg.c and 1025 deg.c. And carrying out constant temperature test on the first bus duct according to the four temperatures.

Further, as shown in fig. 3, in the generating the first processing scheme according to the first processing temperature threshold by using the control variable method, step S500 of the embodiment of the present application further includes:

step S540: extracting a first temperature interval of the plurality of temperature intervals, and screening the lowest temperature of the first temperature interval as a first lowest test temperature;

step S580: and determining a first temperature change scheme according to the first temperature change test, and generating the first treatment scheme by combining the first constant temperature scheme.

Specifically, the first temperature zone is any one of a plurality of temperature zones formed by dividing the first processing temperature threshold. Setting the lowest temperature in the first temperature interval as a first lowest test temperature, and taking the highest temperature of the first treatment temperature threshold as the first highest test temperature, thereby obtaining the temperature change range of the temperature change test. The first temperature change test refers to a temperature change test in which the test temperature is randomly changed in the first test temperature range based on a preset temperature change frequency. The preset temperature change frequency refers to the number of times of completing temperature change in unit time, and is set by a worker after comprehensively analyzing the actual use environment, conditions and the like of the first bus duct, and preferably, the higher temperature change frequency is set for a bus duct use area with large day-night temperature difference change. Further, the first treatment scheme can be generated according to the determined first temperature changing scheme and the first constant temperature scheme, wherein the first treatment scheme is a scheme for performing a fire resistance test on the first bus duct by controlling other variables, optionally, wind speed, air pressure, humidity and the like, only changing the temperature, and the like. The fire resistance of the first bus duct can be comprehensively, accurately and efficiently tested, and the fire resistance of the first bus duct can be accurately evaluated.

Illustratively, the first temperature range is 800 ℃ to 850 ℃, the first lowest test temperature is 800 ℃, the highest temperature of the first processing temperature threshold is 1050 ℃, and the first highest test temperature is 1050 ℃. Further, the first test temperature is in the range of 800 to 1050 ℃. And setting the preset temperature change frequency to change the temperature once every half hour, and further determining the first temperature change scheme.

Further, as shown in fig. 4, the performing constant temperature treatment on the first bus duct according to the first constant temperature scheme to obtain a first treatment result, in which step S600 further includes:

step S610: performing constant temperature treatment on the first bus duct according to the first constant temperature scheme;

step S620: the method comprises the steps of detecting in real time by utilizing a thermocouple to obtain a first actual processing temperature, wherein the first actual processing temperature refers to the actual temperature when the first constant temperature scheme carries out constant temperature processing on the first bus duct;

step S630: extracting a first standard processing temperature in the first constant temperature scheme;

step S640: and calculating to obtain a first temperature error according to the first standard processing temperature and the first actual processing temperature.

Specifically, in the constant temperature treatment of the first bus duct according to the first constant temperature scheme, the actual treatment temperature is detected in real time to be compared with the treatment temperature in the scheme, so that the temperature control error condition is obtained. Wherein, the real-time detection of the temperature is realized by a thermocouple. The first actual processing temperature refers to an actual processing temperature when the first bus duct is subjected to constant temperature processing according to the first constant temperature scheme, namely, a real-time detection temperature in a test process. The first standard processing temperature refers to an average temperature value obtained by calculating an average temperature of each temperature interval after the temperature intervals, wherein each temperature interval corresponds to one average temperature value, and each average temperature value is used as the standard processing temperature when the temperature interval is subjected to constant temperature processing. And extracting the first standard processing temperature of the first constant-temperature scheme, and preferably, searching the scheme by taking the temperature as a keyword to obtain the first standard processing temperature. Thus, the first temperature error can be calculated according to the first standard processing temperature and the first actual processing temperature. The first temperature error is a temperature difference between a temperature set in a test scheme and a temperature in an actual test. Temperature error change data along with processing time is obtained through real-time detection and calculation, and the technical aim of intuitively quantifying the test error is achieved. The method has the advantages that basis is provided for screening a test scheme in the follow-up process, and the accuracy of evaluating the fire resistance of the first bus duct is improved.

step S730: and performing failure check and analysis on the first processing result according to the first analysis scheme to obtain the first analysis result.

Specifically, the first preset temperature error threshold value refers to a preset error range, and if the difference between the actual test temperature and the standard test temperature in the test scheme is within the range, the influence of the temperature error on the test result is considered to be negligible. Specifically, the first preset temperature error threshold may be set by a worker, which is not limited herein. If the first temperature error does not meet the first preset temperature error threshold, the corresponding temperature control error of the constant temperature test is too large to be used as a basis for evaluating the fire resistance of the first bus duct, and the first bus duct is removed. And forming the first analysis scheme according to the constant temperature treatment result obtained after the removal and screening. The first analysis scheme is a specific scheme for further analyzing the fire resistance of the first bus duct, wherein the specific scheme is obtained by analyzing the test result. And performing failure detection and analysis on the first processing result, wherein the failure detection and analysis is mainly used for analyzing whether the conductive function of the first bus duct is good or not and whether the circuit integrity can be maintained in a flame state or not in a certain time so as to judge whether the first bus duct fails or not. Thereby realizing the technical effects of improving the precision of the test and improving the accuracy of the fire resistance evaluation of the first bus duct.

Further, in the step of determining whether the first temperature error meets the first preset temperature error threshold, step S710 of the embodiment of the present application further includes:

step S711: if the first temperature error accords with the first preset temperature error threshold value, a first judging instruction is obtained;

step S712: judging whether the first temperature error accords with a second preset temperature error threshold according to the first judging instruction, and obtaining a first judging result, wherein the second preset temperature error threshold is within the first preset temperature error threshold;

step S713: according to the first judgment result, if the first temperature error does not accord with the second preset temperature error threshold value, a first adjustment instruction is obtained;

step S714: and adjusting the first actual processing temperature by using an intelligent temperature control model according to the first adjustment instruction, wherein the intelligent temperature control model is constructed based on a synovial membrane control algorithm.

Specifically, the first temperature error accords with the first preset temperature error threshold, which means that the test temperature is within the error allowable range in the process of evaluating the first bus duct, and further, whether the first temperature error accords with the second preset temperature error threshold is determined, the test data is more accurately determined and screened, and fine adjustment is performed within the error threshold meeting range. The first judging instruction refers to an adjusting instruction for more accurately judging the first temperature error under the condition that the first temperature error meets the first preset temperature error threshold value. The second preset temperature error threshold is an error allowable range smaller than the first preset temperature error threshold within the first preset temperature error threshold. The intelligent temperature control model is constructed based on a synovial membrane control algorithm, and preferably, the synovial membrane control algorithm is a differential optimization synovial membrane control algorithm. The accuracy of the constant temperature test can be further improved, and meanwhile, the controller based on the differential optimization sliding mode variable structure control strategy has the technical effects of sensitive response, good prediction accuracy, strong stability, small overshoot and better test evaluation on the fire resistance of the first bus duct.

Further, in the generating the first fire resistance evaluation of the first bus duct according to the first analysis result and the second analysis result, step S800 of the embodiment of the present application further includes:

step S810: according to the first analysis result, a first constant-temperature fire resistance evaluation of the first bus duct is obtained, wherein the first constant-temperature fire resistance evaluation comprises a first fire resistance temperature value and a first fire resistance duration;

step S840: and carrying out weighted calculation on the first data processing result by using a variation coefficient method to generate the first fire resistance evaluation.

Specifically, a first constant-temperature fire resistance evaluation of the first bus duct and a first alternating fire resistance evaluation of the first bus duct are respectively obtained according to the first analysis result and the second analysis result, wherein the obtained fire resistance evaluation is a judgment on a fire resistance temperature value and a fire resistance time. The first refractory temperature value is the highest temperature value which can be born by the first bus duct in a constant temperature test. The first refractory duration is the longest operating time that the first bus duct can withstand at the highest temperature in a constant temperature test. The first refractory temperature range is a temperature range that the first bus duct can withstand in a temperature change test.

Therefore, the obtained first fire resistance evaluation is the evaluation of the fire resistance performance of the first bus duct, and the technical effects of stably evaluating the fire resistance performance of the ceramic matrix composite bus duct, reducing the detection times and cost and improving the evaluation precision can be realized.

In summary, the method for evaluating the fire resistance of the ceramic matrix composite bus duct provided by the application has the following technical effects:

1. acquiring first historical use data of a first bus duct, and screening the first historical use data to obtain first target use data; comparing the first target usage data to obtain a first fire resistance pre-evaluation; collecting first basic information of the first bus duct, wherein the first basic information comprises a first fire resistance requirement; determining a first treatment condition based on the first fire resistance requirement and the first fire resistance pre-evaluation; generating a first treatment scheme by using a control variable method according to the first treatment temperature threshold, wherein the first treatment scheme comprises a first constant temperature scheme and a first variable temperature scheme; performing constant temperature treatment on the first bus duct according to the first constant temperature scheme to obtain a first treatment result, and performing variable temperature treatment on the first bus duct according to the first variable temperature scheme to obtain a second treatment result; sequentially performing failure inspection and analysis on the first processing result and the second processing result to obtain a first analysis result and a second analysis result respectively; and generating a first fire resistance evaluation of the first bus duct according to the first analysis result and the second analysis result.

2. Gradient division is carried out on the first processing temperature threshold value, and first division results are respectively obtained, wherein the first division results comprise a plurality of temperature intervals; sequentially calculating each temperature interval in the temperature intervals to obtain a plurality of average temperatures, wherein the average temperatures correspond to the temperature intervals one by one; and respectively designing a plurality of constant temperature tests according to the average temperatures, wherein the constant temperature tests form the first constant temperature scheme.

3. By setting the temperature errors of two different thresholds, the relation between the actual temperature and two preset temperature error thresholds is judged in real time after the temperature in the test is obtained by utilizing the thermocouple to detect in real time. When the first preset temperature error threshold is met and the second preset temperature error threshold is not met, the intelligent temperature control model is utilized to conduct dynamic temperature adjustment, so that the temperature error is reduced; and when the temperature error does not accord with the first preset temperature error threshold value, the corresponding test result is directly removed, so that the reliability of analysis of the test result is prevented from being influenced by excessive temperature error.
