The environmental state characteristic value is obtained by weighted summation of the time-varying value, the performance value of the loop state, and the time-varying amplitude value.

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application, obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0035] Embodiment one: as Figure 1As shown, the application proposes a heat conduction performance detection system suitable for stainless steel heaters, which includes a heating simulation control module, a non-contact infrared temperature measurement array module, a data acquisition and processing module, a heat conduction characteristic analysis module, a performance evaluation report generation module, and a touch control display module.

[0036] According to the specification parameters (such as power, size, etc.) of the stainless steel heater to be detected and the expected working conditions (such as heating temperature range, heating time, etc.), the operator inputs the corresponding control parameters through the touch control display module. After the heating simulation control module receives these parameters, the internal control circuit starts to work, controls the output power and output time of the heating power supply according to the preset logic and algorithm, and simulates the heating process of the stainless steel heater in the actual working scenario.

[0037] At the same time, the heating simulation control module will transmit the current actual heating parameters (such as actual output power, heating time, etc.) to the data acquisition and processing module in real time to provide basic data for subsequent data analysis.

[0038] The non-contact infrared temperature measurement array module is composed of multiple high-precision temperature sensors. These sensors are reasonably arranged at different key positions of the stainless steel heater, such as the surface position of the heater and the vicinity of the internal heating element. After the heating simulation control module starts the heating process, each temperature sensor starts to work, responsible for real-time monitoring of the temperature change of the stainless steel heater during the heating process, and converts the collected temperature signals into electrical signals and transmits these electrical signals to the data acquisition and processing module.

[0039] The data acquisition and processing module is responsible for receiving data transmitted from the heating simulation control module and the non-contact infrared temperature measurement array module, and processing and storing these data. The specific processing process of the data acquisition and processing module is as follows:

[0040] First, the received data is subjected to preliminary verification and filtering processing to remove existing noise and abnormal data, thereby improving the accuracy and reliability of the data. Then, the processed data is classified and arranged, and the heating parameters and corresponding temperature data are associated and stored according to the time sequence to form a complete data set. At the same time, preliminary statistical analysis is performed on the data, such as calculating the average, maximum and minimum values of the temperature at each position, and transmitting these statistical results to the heat conduction characteristic analysis module to provide data support for further analysis.

[0041] The heat conduction characteristic analysis module deeply analyzes the heat conduction characteristics of the stainless steel heater according to the data provided by the data acquisition and processing module, and sends the analysis results to the performance evaluation report generation module. The specific operation process of the heat conduction characteristic analysis module includes:

[0042] The system receives data from the data acquisition and processing module and first analyzes the temperature change curves of various locations on the stainless steel heater over time. By observing the shape and slope of the curves, it makes a preliminary judgment on the heat transfer rate and temperature distribution uniformity of the stainless steel heater. Then, it combines the actual heating parameters provided by the heating simulation control module to analyze the differences in heat transfer performance of the stainless steel heater under different heating conditions. For example, by comparing the temperature changes of various parts of the heater under different output powers, it evaluates the heat transfer efficiency of the heater under different working conditions.

[0043] In addition, the thermal conduction characteristic analysis module will use specific analysis algorithms to estimate key thermal conduction parameters such as thermal resistance and thermal diffusivity of stainless steel heaters, thereby gaining a comprehensive and in-depth understanding of the heater's thermal conduction performance. After the analysis is completed, the thermal conduction characteristic analysis module will transmit the analysis results to the performance evaluation report generation module in a structured data format.

[0044] The performance evaluation report generation module generates an intuitive thermal conductivity performance evaluation report based on the analysis results provided by the thermal conductivity characteristic analysis module, and sends the thermal conductivity performance evaluation report of the stainless steel heater to the touch screen display module for display. The specific operation process of the performance evaluation report generation module includes:

[0045] The system receives the analysis results from the heat conduction characteristic analysis module, first formats the data, arranges various analysis data and conclusions in a certain logical order, and then comprehensively evaluates the heat conduction performance of the stainless steel heater according to the preset evaluation standards and rules, and gives the corresponding performance level (such as excellent, good, average, poor, etc.).

[0046] When generating the report, the evaluation results are presented in various formats, including text descriptions and charts, enabling users to clearly understand the advantages and disadvantages of the heater's heat transfer performance. Finally, the performance evaluation report generation module generates a complete evaluation report and displays it to the user via a touch-screen display module. Users can also export the report to common file formats (such as PDF and Word) for archiving and sharing.

[0047] Example 2: Figure 2 As shown, the difference between this embodiment and embodiment one is that the heating simulation control module is communicatively connected to the power supply working status evaluation module. The heating simulation control module sends the operating information of the heating power supply to the power supply working status evaluation module. The power supply working status evaluation module analyzes and evaluates the working status of the heating power supply to generate a working status failure signal or a working status qualification signal.

[0048] The working state unqualified signal is sent to the touch control display module for display when generated, and the touch control display module sends out corresponding early warning when receiving the working state unqualified signal, so as to remind the operator to investigate and analyze the cause and check, control or repair and replace the heating power supply, so as to ensure the heating effect and running stability and safety of the heating power supply, which is beneficial to ensure the accuracy of the heat conduction detection result of the stainless steel heater; the specific analysis process of the power supply working state evaluation module is as follows:

[0049] The voltage curve and power curve of the heating power supply in a unit time are collected, the standard deviation of the actual voltage value of the heating power supply in a unit time is obtained and marked as a voltage standard deviation coefficient, and the standard deviation of the actual power value of the heating power supply in a unit time is marked as a power standard deviation coefficient. The voltage standard deviation coefficient and the power standard deviation coefficient are compared with the preset voltage standard deviation coefficient threshold and the preset power standard deviation coefficient threshold respectively. If the voltage standard deviation coefficient or the power standard deviation coefficient exceeds the corresponding preset threshold, it indicates that the stability of the voltage or power of the heating power supply is poor, and the working state of the heating power supply is poor, and a working state unqualified signal of the heating power supply is generated;

[0050] If the voltage standard deviation coefficient and the power standard deviation coefficient do not exceed the corresponding preset threshold, then when the deviation of the actual voltage value from the set voltage value is not within the allowable voltage deviation range or the deviation of the actual power from the set power value is not within the allowable power deviation range, it indicates that the real-time running condition of the heating power supply is poor, and it is judged that the heating power supply is in an abnormal running state;

[0051] The total duration of the heating power supply in the abnormal running state in a unit time is obtained and marked as a state abnormal time value. The state abnormal time value is compared with the preset state abnormal time threshold. If the state abnormal time value exceeds the preset state abnormal time threshold, it indicates that the working state of the heating power supply is poor, which is not conducive to ensuring the accuracy of the heat conduction detection result and the stability of the detection process, and a working state unqualified signal of the heating power supply is generated.

[0052] Further, if the state abnormal time value does not exceed the preset state abnormal time threshold, the maximum deviation value of the actual voltage value of the heating power supply from the set voltage value in a unit time is collected and marked as a voltage abnormal characteristic value, and the maximum deviation value of the actual power of the heating power supply from the set power value in a unit time is collected and marked as a power abnormal characteristic value;

[0053] The power supply state characteristic value is obtained by weighted summation of the state anomaly value, voltage anomaly characteristic value, and power anomaly characteristic value. Specifically, each of the state anomaly value, voltage anomaly characteristic value, and power anomaly characteristic value is assigned a corresponding preset weight coefficient, and then each of these values ​​is multiplied by its respective preset weight coefficient. The sum of these three products is then marked as the power supply state characteristic value. It should be noted that the larger the value of the power supply state characteristic value, the worse the overall operating condition of the heating power supply.

[0054] The power supply status characteristic value is compared with the preset power supply status characteristic threshold. If the power supply status characteristic value exceeds the preset power supply status characteristic threshold, it indicates that the overall working status of the heating power supply is poor, which is not conducive to ensuring the accuracy of the heat conduction detection results and the stability of the detection process. In this case, an unqualified signal for the working status of the heating power supply is generated. If the power supply status characteristic value does not exceed the preset power supply status characteristic threshold, it indicates that the overall working status of the heating power supply is good, which is conducive to ensuring the accuracy of the heat conduction detection results and the stability of the detection process. In this case, a qualified signal for the working status of the heating power supply is generated.

[0055] Example 3: Figure 2 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that the power supply working status assessment module is communicatively connected to the regional environmental status assessment module. The power supply working status assessment module sends a working status qualified signal to the regional environmental status assessment module. When the regional environmental status assessment module receives the working status qualified signal, it assesses the environmental status at the time of the heat conduction detection of the stainless steel heater and generates an environmental status qualified signal or an environmental status unqualified signal accordingly.

[0056] When an environmental condition failure signal is generated, it is sent to the touch-screen control display for display. Upon receiving the failure signal, the touch-screen control display issues a corresponding warning to remind operators to investigate and analyze the cause and adjust the environment accordingly. This ensures the stainless steel heater operates in a suitable environment, reduces the adverse effects of environmental conditions on the heat transfer performance test results, further ensures the accuracy of the heat transfer test results for the stainless steel heater, significantly reduces the difficulty of monitoring the testing process, and demonstrates a high level of intelligence. The specific analysis process of the regional environmental condition assessment module is as follows:

[0057] By deploying platinum resistance temperature sensors or thermocouple temperature sensors at a certain distance from the heater and without being directly affected by the heater's radiation, the ambient temperature of the environment where the stainless steel heater is located can be monitored in real time. A capacitive humidity sensor or a resistive humidity sensor can be used to monitor the ambient humidity of the environment where the stainless steel heater is located in real time. A digital barometer or a mercury barometer can be used to monitor the atmospheric pressure of the environment where the stainless steel heater is located in real time.

[0058] The difference between the ambient temperature and the median of the preset suitable ambient temperature range is calculated and the absolute value is taken to obtain the temperature status value. Similarly, the humidity status value and air pressure status value are obtained. The airflow velocity is measured in real time by a hot-wire anemometer or impeller anemometer deployed around the heater, and the real-time airflow velocity is marked as the air velocity status value.

[0059] The measured ambient temperature value is obtained by weighted summation of temperature, humidity, air pressure, and air velocity values. Specifically, each of these values ​​is assigned a pre-defined weighting coefficient, and each is multiplied by its respective weighting coefficient. The sum of these four products is then recorded as the measured ambient temperature value. It should be noted that a higher measured ambient temperature value indicates a generally worse real-time environmental condition in the detection area of ​​the stainless steel heater.

[0060] The measured values ​​of the ambient state are compared with the preset ambient state measurement threshold. If the measured values ​​of the ambient state exceed the preset ambient state measurement threshold, it indicates that the real-time environmental conditions of the detection area of ​​the stainless steel heater are generally poor. Therefore, it is determined that the current environment of the stainless steel heater is under monitoring influence.

[0061] The total duration of the environment under monitoring influence within a unit of time is obtained and marked as the time-varying value. The time-varying value is compared with the preset time-varying threshold. If the time-varying value exceeds the preset time-varying threshold, it indicates that the environmental control performance of the environment where the stainless steel heater is located within a unit of time is poor, which is not conducive to ensuring the accuracy of the heat conduction detection results. In this case, an environmental condition unqualified signal is generated.

[0062] Furthermore, if the time-varying value of the loop state does not exceed the preset time-varying threshold, the average of all measured loop state values ​​within a unit time is calculated to obtain the loop state performance value, and the measured loop state value with the largest value within a unit time is marked as the time-varying amplitude value.

[0063] The environmental state characteristic value is obtained by weighted summation of the time-varying environmental values, environmental performance values, and environmental amplitude values. Specifically, each of the time-varying environmental values, environmental performance values, and environmental amplitude values ​​is assigned a corresponding preset weight coefficient, and then multiplied by the corresponding preset weight coefficient. The sum of the three products is then marked as the environmental state characteristic value. It should be noted that the larger the value of the environmental state characteristic value, the worse the overall environmental control performance of the environment in which the stainless steel heater is located per unit time, and the less conducive it is to ensuring the accuracy of the heat conduction detection results.

[0064] The environmental state characteristic value is compared with a preset environmental state characteristic threshold value, if the environmental state characteristic value exceeds the preset environmental state characteristic threshold value, it indicates that the environmental control performance of the environment in which the stainless steel heater is located is poor in the unit time, which is not conducive to ensuring the accuracy of the heat conduction detection result, and an environmental state unqualified signal is generated, if the environmental state characteristic value does not exceed the preset environmental state characteristic threshold value, it indicates that the environmental control performance of the environment in which the stainless steel heater is located is good in the unit time, which is conducive to ensuring the accuracy of the heat conduction detection result, and an environmental state qualified signal is generated.

[0065] The working principle of the present application is as follows: when in use, the heating simulation control module controls the working of the heating power supply according to the set parameters, at the same time, the non-contact infrared temperature measurement array module collects temperature data in real time, the data acquisition and processing module processes and stores the received data, and transmits the preliminary statistical results to the heat conduction characteristic analysis module, the heat conduction characteristic analysis module performs in-depth analysis and estimates the key heat conduction parameters according to the data, and transmits the analysis results to the performance evaluation report generation module, the performance evaluation report generation module generates a performance evaluation report according to the analysis results and displays it to the user, which can accurately reflect the heat conduction characteristics of the heater in the actual working state and intuitively display, and through the power supply working state evaluation module, the working state of the heating power supply is analyzed and evaluated, when the working state qualified signal is generated, the environmental state evaluation module is used to evaluate the environmental state of the stainless steel heater during the heat conduction detection, which facilitates the operator to take corresponding control improvement measures in time, ensures the accuracy of the heat conduction detection result of the stainless steel heater, significantly reduces the supervision difficulty of the detection process, and has high intelligent level.

[0066] The preferred embodiments of the present application disclosed above are only used to help explain the present application, the setting of the threshold value in the technical solution is for result comparison and analysis, so as to determine whether it is good or not, and the size of the threshold value is determined according to the large model analysis of sample data and the combination of artificial experience, and is also adjusted appropriately according to the seasonal or rational influence conditions.

Obviously, many modifications and changes can be made according to the content of the present application.
