As shown in Figure 1, this application provides a method for evaluating the fire resistance of ceramic-based composite bus ducts, wherein the method is applied to an evaluation system for the fire-resistant performance of ceramic-based composite bus ducts. The method Specifically, it includes the following steps:

Step S100: Collect the first historical usage data of the first bus duct, and filter the first historical usage data to obtain the first target usage data;

Specifically, the first bus duct refers to a ceramic-based composite fire-resistant bus duct specially used for the power supply of fire-fighting equipment. This type of bus duct has good heat resistance and insulation, and the outer casing is made of high-temperature-resistant fire-proof materials and insulation. Material. Preferably, fireproof materials with a high temperature resistance of ≥1100°C and insulating materials with a high temperature resistance of ≥300°C are used. The first historical usage data is the usage data generated during the use of the first bus duct, including usage environment, load, maximum temperature endured, average heating temperature, heating temperature at the time of failure, usage time, failure reason, and fire. The integrity of the rear lines and maintenance records, etc. The filtering of the first historical usage data refers to filtering out end-of-life cases whose failure causes are poor fire resistance from the first historical usage data, and obtaining the historical records of all cases, which are the first targets. Usage Data. By finding the historical data of bus duct failure due to poor fire resistance from the historical usage, we can provide a data basis and data support for the subsequent preliminary analysis of the bus duct's historical usage and estimate its fire resistance, and provide a basis for subsequent evaluation of the fire resistance of the bus duct. Evaluate the technical effectiveness of providing reference data.

Step S200: Compare the first target usage data to obtain a first fire resistance pre-evaluation, where the first fire resistance pre-evaluation refers to a preliminary evaluation of the fire resistance performance of the first bus duct;

Specifically, the comparison of the first target usage data refers to comparative analysis of the historical usage of the first bus duct to obtain the temperature conditions and failure reasons when the first target failed. Based on the obtained information such as the degree of correlation with temperature, fire resistance time, etc., the first fire resistance pre-evaluation is performed on the first bus duct. The first fire resistance pre-evaluation is a preliminary evaluation of the fire resistance of the first busbar duct based on historical usage conditions, including historical data such as maximum fire resistance temperature, fire resistance duration, etc. Preferably, based on multiple historical bus duct failure cases caused by insufficient fire resistance, extract the temperature when the bus duct failed and the working time at the corresponding temperature in each case, and take the record with the highest temperature and the longest working time as the record. Preliminary evaluation of bus duct. By performing fire resistance pre-evaluation on the first bus duct, the technical effect of paving the way for determining the temperature range for subsequent temperature tests, reducing detection operations, and reducing detection costs can be achieved.

For example, according to the fire resistance time when the first target fails, the first fire resistance pre-evaluation can be divided into four levels. A fire resistance time of 60 minutes can be rated as the first level, and a fire resistance time of 90 minutes can be rated as the second level. , the fire resistance time is 120 minutes and can be rated as level 3, and the fire resistance time is 180 minutes and it can be rated as level 4.

Step S300: Collect first basic information of the first bus duct, where the first basic information includes a first fire resistance requirement;

Specifically, the first basic information of the first bus duct includes: production batch, production process, production model, ceramic ratio of composite materials, composite method, length of use in a fire environment, and the temperature it can withstand in a fire. wait. The first fire resistance requirement refers to the fire resistance temperature value and the fire resistance duration. The fire resistance temperature value refers to the maximum temperature that can be withstood in a fire environment. The fire resistance duration refers to the ability to maintain circuit integrity in a fire environment. the longest time. 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: Determine a first processing condition according to the first refractory requirement and the first refractory pre-evaluation, wherein the first processing condition includes a first processing temperature threshold;

Specifically, based on obtaining the first fire resistance requirement and the first fire resistance pre-evaluation, a first processing condition for measuring the fire resistance performance test of the first bus duct may be determined. The first treatment conditions refer to the specific test conditions in the fire resistance performance test of the first bus duct, including the temperature conditions of the test and the duration of the test. The first processing temperature threshold refers to the processing temperature range for the first busbar duct obtained based on the first fire resistance requirement and the first fire resistance pre-evaluation, that is, the temperature range in the fire resistance performance test. Wherein, the first refractory requirement is taken as the minimum test temperature, that is, the lower limit of the first treatment temperature threshold, and the highest temperature evaluation in the first refractory pre-evaluation is taken as the maximum test temperature, that is, the lower limit of the first treatment temperature threshold. upper limit. This can achieve the technical effect of accurately determining the temperature range of the test, effectively reducing the amount of tests, thereby reducing the test time, improving the test efficiency, and thereby improving the efficiency of fire resistance performance evaluation of the first bus duct.

Step S500: Use the control variable method to generate a first treatment plan according to the first treatment temperature threshold, where the first treatment plan includes a first constant temperature plan and a first variable temperature plan;

Specifically, based on the obtained test temperature range, the first treatment plan is generated by a control variable method. Since there are many variables that characterize the first bus duct, it is necessary to analyze and evaluate the factors that mainly affect the fire resistance performance of the first bus duct through the control variable method. The first treatment plan refers to performing a test treatment on the first bus duct by controlling other variables, optionally, wind speed, air pressure, humidity, etc., and changing only the variable temperature. The first constant temperature solution is to adjust the test temperature to a fixed value, and use different fixed temperatures to test the first bus duct multiple times. The first temperature change plan is to set a temperature range, and conduct random changes in temperature within the temperature range to test the first bus duct. As a result, the fire resistance performance of the first bus duct can be further tested by controlling the temperature parameters, thereby achieving the technical effect of improving the accuracy of the fire resistance performance test of the bus duct.

Step S600: Perform constant temperature treatment on the first bus duct according to the first constant temperature scheme to obtain a first processing result, and perform temperature changing treatment on the first bus duct according to the first temperature changing scheme to obtain a second processing result. ;

Specifically, the first processing result is the condition of the bus duct after the constant temperature treatment of the first bus duct, including: whether the internal circuit is complete, whether it has failed, how long it will take to fail, and whether it can be powered on and work, etc. The second processing result is the condition of the bus duct after the temperature change treatment of the first bus duct, including: whether the internal circuit is complete, whether it has failed, how long it will take to fail, and whether it can be powered on and work, etc. This has the technical effect of providing basic analysis data for subsequent failure inspection and analysis.

Step S700: Perform failure inspection and analysis on the first processing result and the second processing result in sequence, and obtain the first analysis result and the second analysis result respectively;

Specifically, the failure inspection and analysis of the first processing result and the second processing result in sequence refer to the relevant parameters characterizing the performance of the first bus duct in the inspection processing results. Preferably, the relevant The parameters can be: the appearance parameters of the bus duct, the temperature rise parameters of the bus duct shell, the temperature rise parameters of the surface of the insulating parts in the trough, etc. And by checking whether the conductive function of the first bus duct is intact and whether the circuit integrity can be maintained under the flame state for a certain period of time, it is judged whether the first bus duct has failed. The first analysis result is the maximum temperature that the bus duct can withstand under constant temperature conditions and the maximum working time that it can maintain at each high temperature. The second analysis result is the highest temperature range that the bus duct can withstand under a temperature change state, and the longest working time that it can maintain in each temperature change range. This achieves the technical effect of providing reliable test data for subsequent fire resistance evaluation of the first bus duct.

Step S800: Generate a first fire resistance evaluation of the first bus duct based on the first analysis result and the second analysis result.

Specifically, 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, optionally, such as fire resistance time, fire resistance temperature, etc., to analyze The fire resistance of the first bus duct under variable and constant temperature conditions was analyzed. Achieve stable and comprehensive evaluation of the fire-resistant performance of ceramic-based composite bus ducts, with strong operability, reduce testing costs, and improve the technical effect of testing efficiency and accuracy by improving the intelligence of fire-resistant performance testing.

Further, as shown in Figure 2, in generating the first processing solution using the control variable method according to the first processing temperature threshold, step S500 of the embodiment of the present application also includes:

Step S510: Perform gradient division on the first processing temperature threshold to obtain first division results, wherein the first division results include multiple temperature intervals;

Step S520: Calculate each temperature interval in the plurality of temperature intervals in turn to obtain multiple average temperatures, wherein the multiple average temperatures correspond to the multiple temperature intervals in a one-to-one manner;

Step S530: Design multiple constant temperature tests according to the multiple average temperatures, and the multiple constant temperature tests constitute the first constant temperature solution.

Specifically, after obtaining the first processing temperature threshold, the temperature interval is divided according to the gradient to obtain the first division result. The first division result includes a plurality of temperature intervals. Calculate the average temperature for each temperature range. Since there is little difference in the degree of impact on the fire resistance of the first bus duct in each temperature range, the average value can be taken to reduce the number of tests, improve test efficiency and reduce test costs. . Then, multiple constant temperature tests are respectively designed according to the multiple average temperatures, and the multiple constant temperature tests constitute the first constant temperature solution, where the multiple average temperatures correspond to the multiple temperature intervals one-to-one. As a result, a technical solution for testing the fire resistance performance of the first busbar duct at a constant temperature was constructed, which laid a foundation for the subsequent evaluation of the fire resistance performance of the first busbar duct.

Exemplarily, the first processing temperature threshold is 800°C to 1050°C. The first processing temperature threshold is divided according to changes in the fire resistance of the first bus duct in different temperature nodes, so The above nodes are: 850℃, 900℃, 1050℃. The divided temperature ranges are 800°C ~ 850°C, 850°C ~ 900°C, 900°C ~ 1000°C, and 1000°C ~ 1050°C. According to the average values of the above four temperature intervals, the temperatures corresponding to the four constant temperature tests are obtained: : 825℃, 875℃, 950℃, 1025℃. Conduct a constant temperature test on the first bus duct based on the above four temperatures.

Further, as shown in Figure 3, in generating the first processing solution using the control variable method according to the first processing temperature threshold, step S500 of the embodiment of the present application also includes:

Step S540: Extract the first temperature interval of the plurality of temperature intervals, and filter the lowest temperature of the first temperature interval as the first lowest test temperature;

Step S550: Extract the highest temperature of the first processing temperature threshold as the first highest test temperature;

Step S560: Determine the first test temperature range according to the first minimum test temperature and the first maximum test temperature;

Step S570: Obtain a first temperature change test, wherein the first temperature change test refers to a temperature change test in which the test temperature randomly changes in the first test temperature range based on a preset temperature change frequency;

Step S580: Determine a first temperature change plan according to the first temperature change test, and generate the first treatment plan in combination with the first constant temperature plan.

Specifically, the first temperature interval is any one of a plurality of temperature intervals formed by dividing the first processing temperature threshold. The lowest temperature in the first temperature interval is set as the first lowest test temperature, and the highest temperature of the first processing temperature threshold is set 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 randomly changes in the first test temperature range based on a preset temperature change frequency. The preset temperature changing frequency refers to the number of temperature changes per unit time that is set in advance and is set by the staff after a comprehensive analysis of the actual use environment and conditions of the first bus duct. It is preferred for bus ducts with large temperature differences between day and night. Use the area to set a higher frequency of temperature changes. Further, the first treatment plan can be generated according to the determined first temperature change plan and the first constant temperature plan, wherein the first treatment plan is by controlling other variables, optionally, wind speed, air pressure, Humidity, etc., only change the variable of temperature to conduct a test treatment on the first bus duct, and conduct a fire resistance test on the first bus duct based on the two conditions of constant temperature and variable temperature. The technical effect of comprehensively, accurately and efficiently testing the fire resistance of the first bus duct and then accurately evaluating its fire resistance can be achieved.

For example, if the first temperature range is 800°C to 850°C, then the first lowest test temperature is 800°C, and the highest temperature of the first processing temperature threshold is 1050°C, then the first highest test temperature The temperature is 1050℃. Furthermore, it is obtained that the first test temperature range is 800°C to 1050°C. The preset temperature changing frequency is set to change the temperature every half an hour, and then the first temperature changing plan is determined.

Further, as shown in Figure 4, in performing constant temperature treatment on the first busbar duct according to the first constant temperature scheme and obtaining the first processing result, step S600 of the embodiment of the present application also includes:

Step S610: Perform constant temperature treatment on the first bus duct according to the first constant temperature scheme;

Step S620: Use thermocouple real-time detection to obtain the first actual processing temperature, where the first actual processing temperature refers to the actual temperature when the first constant temperature solution performs constant temperature treatment on the first bus duct;

Step S630: Extract the first standard processing temperature in the first constant temperature scheme;

Step S640: Calculate and obtain a first temperature error based on the first standard processing temperature and the first actual processing temperature.

Specifically, during the constant temperature treatment of the first busbar duct according to the first constant temperature plan, the actual treatment temperature is detected in real time and compared with the treatment temperature in the plan to obtain the temperature control error. Among them, real-time detection of temperature is achieved through thermocouples. The first actual processing temperature refers to the actual processing temperature when the first bus duct is subjected to constant temperature treatment according to the first constant temperature scheme, that is, it is the real-time detected temperature during the test process. The first standard processing temperature refers to calculating the average temperature of each temperature interval to obtain an average temperature value after the plurality of temperature intervals are mentioned, wherein each of the plurality of temperature intervals corresponds to an average temperature value, and Each average temperature value is used as the standard processing temperature during constant temperature treatment in this temperature range. To extract the first standard processing temperature of the first constant temperature scheme, preferably, the first standard processing temperature is obtained by searching the scheme with "temperature" as a keyword. Therefore, the first temperature error can be calculated based on the first standard processing temperature and the first actual processing temperature. Wherein, the first temperature error is the temperature difference between the temperature set in the test plan and the temperature in the actual test. Through real-time detection and calculation, the temperature error change data with the passage of processing time is obtained, achieving the technical goal of intuitively quantifying the experimental error. This achieves the technical effect of providing a basis for subsequent screening of test plans and improving the accuracy of evaluating the fire resistance performance of the first bus duct.

Further, in obtaining the first analysis result, step S700 in this embodiment of the present application also includes:

Step S710: Determine whether the first temperature error meets the first preset temperature error threshold;

Step S720: If the first temperature error does not meet the first preset temperature error threshold, remove the processing results corresponding to the constant temperature test and generate a first analysis plan;

Step S730: According to the first analysis plan, perform failure inspection and analysis on the first processing result to obtain the first analysis result.

Specifically, the first preset temperature error threshold refers to a preset error range. If the difference between the actual test temperature and the standard test temperature in the test plan is within this range, it is considered that the temperature error has a negative impact on the test results. The impact is negligible. Specifically, the first preset temperature error threshold can be set by the staff themselves, and is not limited here. If the first temperature error does not meet the first preset temperature error threshold, it means that the corresponding constant temperature test temperature control error is too large and cannot be used to evaluate the fire resistance of the first bus duct. The basis should be eliminated. The first analysis plan is formed based on the constant temperature treatment results obtained after elimination and screening. The first analysis plan refers to a specific plan for further analyzing the fire resistance of the first bus duct obtained by analyzing the test results. The failure inspection and analysis of the first processing result is mainly to analyze whether the conductive function of the first bus duct is intact and whether the circuit integrity can be maintained under the flame state for a certain period of time to determine whether the first bus duct is Invalid. This achieves the technical effect of improving the accuracy of the test and improving the accuracy of the fire resistance performance evaluation of the first bus duct.

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

Step S711: If the first temperature error meets the first preset temperature error threshold, obtain a first judgment instruction;

Step S712: According to the first judgment instruction, judge whether the first temperature error meets a second preset temperature error threshold, and obtain a first judgment result, wherein the second preset temperature error threshold is within the first Within the preset temperature error threshold;

Step S713: According to the first judgment result, if the first temperature error does not meet the second preset temperature error threshold, obtain a first adjustment instruction;

Step S714: According to the first adjustment instruction, use an intelligent temperature control model to adjust the first actual processing temperature, wherein the intelligent temperature control model is constructed based on a synovial membrane control algorithm.

Specifically, the first temperature error complies with the first preset temperature error threshold, indicating that the data of the constant temperature test is that the test temperature is within the allowable error range during the evaluation of the first bus duct. Further, determining whether the first temperature error meets the second preset temperature error threshold is to conduct more accurate judgment and screening of the test data, and make fine adjustments within the range that meets the error threshold. Wherein, the first judgment instruction refers to an adjustment instruction for making a more accurate judgment on the first temperature error when the first temperature error has met the first preset temperature error threshold. The second preset temperature error threshold is an error allowable range within the first preset temperature error threshold that is smaller than the first preset temperature error threshold. Wherein, the first actual processing temperature is adjusted using an intelligent temperature control model, and the intelligent temperature control model is constructed based on a synovial membrane control algorithm. 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. At the same time, the controller based on the differential optimized sliding mode variable structure control strategy has sensitive response, good prediction accuracy, strong stability and small overshoot, which can better control the first The technical effect of testing and evaluating the fire resistance of bus duct.

Further, in generating the first fire resistance evaluation of the first bus duct based on the first analysis result and the second analysis result, step S800 in the embodiment of the present application also includes:

Step S810: According to the first analysis result, obtain a first constant temperature fire resistance evaluation of the first busbar duct, wherein the first constant temperature fire resistance evaluation includes a first fire resistance temperature value and a first fire resistance duration;

Step S820: According to the second analysis result, obtain a first alternating fire resistance evaluation of the first bus duct, wherein the first alternating fire resistance evaluation includes a first refractory temperature range and a second refractory duration;

Step S830: Perform normalization processing on the first refractory temperature value, the first refractory duration, the first refractory temperature range, and the second refractory duration in sequence to obtain a first data processing result;

Step S840: Use the coefficient of variation method to perform weighted calculation on the first data processing result to generate the first fire resistance evaluation.

Specifically, the first constant temperature fire resistance evaluation of the first busbar duct and the first alternating fire resistance evaluation of the first busbar duct are respectively obtained according to the first analysis result and the second analysis result, wherein, we obtain The fire resistance evaluation is a judgment of the fire resistance temperature value and fire resistance time. The first refractory temperature value refers to the highest temperature value that the first busbar duct can withstand during the constant temperature test. The first fire-resistant duration is the longest working time that the first busway can withstand at the highest temperature in the constant temperature test.
