[0060] The present application is further described in detail below in conjunction with the accompanying drawings.

[0061] In one embodiment, if Figure 1 As shown, the present application discloses an integrated heating tape energization test detection method, which specifically includes the following steps:

[0062] S10: receiving a preset detection condition, and controlling the current output according to the preset detection condition.

[0063] Specifically, after receiving the detection conditions, the output current is adjusted according to the set current, temperature and other detection parameters to ensure that the output current meets the preset conditions. The current control module adjusts the current output in real time according to the input parameters to ensure that the heating tape is always within a safe current range during the power-on test, thereby ensuring the accuracy and safety of the test data.

[0064] S20: Obtain the insulation resistance and corresponding real-time temperature data of the heating tape, perform temperature compensation on the insulation resistance according to the real-time temperature data to obtain compensated resistance data, and then detect and determine whether there is current leakage in the heating tape when power is turned on according to the compensated resistance data, and generate an insulation test result.

[0065] Specifically, the real-time temperature of the heating tape and the preliminary measured insulation resistance data are obtained through sensors. Temperature changes will affect the resistance, so the preliminary resistance data needs to be compensated. The compensated resistance value is used to determine whether there is current leakage in the heating tape when power is turned on. If the compensated resistance value exceeds the set safety range, it indicates that there is current leakage in the heating tape, thereby generating an insulation test result.

[0066] S30: Detect the local voltage and current response of the heating cable in real time, and evaluate the voltage resistance of the heating cable through multi-stage high-voltage testing to determine whether there is an electrical fault area and generate a voltage resistance test result.

[0067] Specifically, the voltage and current response of the heating tape is monitored in real time. By gradually increasing the applied voltage, different electrical load states are simulated to detect whether the voltage and current responses are within a safe range. If the current and voltage exceed the safety standards, it is determined that there may be an electrical fault area, and then the voltage resistance test results are generated.

[0068] S40: Obtain the surface temperature change of the heating belt, draw a corresponding thermal curve according to the surface temperature change, and confirm whether there is thermal unevenness in the heating belt based on the thermal curve to generate a thermal performance test result.

[0069] Specifically, temperature data at different positions on the surface of the heating tape is obtained through temperature sensors. The temperature data is processed in real time and plotted into thermal curves. These graphs are used to analyze the temperature distribution on the surface of the heating tape. If the temperature difference is too large or the heat distribution is uneven, the system will mark the thermal unevenness and generate thermal performance test results.

[0070] S50: Generate a standard test report based on the insulation test results, the voltage resistance test results and the thermal performance test results.

[0071] Specifically, based on the results of insulation testing, voltage resistance testing and thermal performance testing, the system will summarize all data and generate a detailed test report, which includes the test conclusions, problem area location and corresponding suggestions. The report will be output in a standard format to ensure that users can clearly understand the test results and take corresponding measures in a timely manner.

[0072] In one embodiment, if Figure 2 As shown, in step S20, temperature compensation is performed on the insulation resistance according to the real-time temperature data to obtain compensation resistance data, and then the compensation resistance data is used to detect and determine whether there is current leakage in the heating belt when it is powered on, specifically including:

[0073] S21: According to the preset temperature compensation formula R 补 =R0×(1+α×(T 时 −T 标 )) and calculate the compensation resistance data, where R 补 is the compensation resistance data, R0 is the insulation resistance, α is the temperature coefficient, T 时 is the real-time temperature data, T 标 It is the standard reference temperature, which indicates the influence of temperature on insulation resistance.

[0074] Specifically, the initial insulation resistance of the heating tape is measured by the insulation resistance test module. This resistance value represents the insulation performance of the heating tape under standard conditions. The working environment temperature of the heating tape is monitored in real time by multiple temperature sensors. The measured insulation resistance is adjusted according to the preset temperature compensation formula to eliminate the influence of temperature change on the resistance value. Specifically, the temperature coefficient will select a suitable value according to different heating tape materials. Through the above compensation formula, the compensated resistance value is obtained, which can more accurately reflect the insulation resistance performance at the actual working temperature.

[0075] S22: If the compensation resistance data is lower than the preset safety threshold, it is determined that there is current leakage in the heating cable.

[0076] Specifically, the compensated resistance data will be compared with a preset safety threshold, which is set based on historical data and safety standards. If the compensated resistance is lower than the threshold, it means that the insulation performance of the heating tape is damaged or degraded, resulting in an increased risk of current leakage. An insulation test report will be generated based on the test results, and the report will include current leakage diagnosis and location of specific problems.

[0077] In one embodiment, if Figure 3 As shown, in step S30, the local voltage and current response of the heating belt is detected in real time, and the pressure resistance of the heating belt is evaluated through a multi-stage high-voltage test to determine whether there is an electrical fault area, which specifically includes:

[0078] S31: Apply a gradually increasing test voltage to the heating cable and monitor the current response of the heating cable in real time.

[0079] Specifically, when conducting a withstand voltage test, a low voltage is first applied to the heating cable and the corresponding current response is monitored. The voltage is then gradually increased to simulate the voltage changes that the heating cable may encounter in actual work. Each time the voltage increases, the current changes are monitored in real time. At each test stage, the current sensor continuously collects current data and records it synchronously with the voltage data to ensure that the electrical characteristics are fully monitored throughout the test process.

[0080] S32: Calculate the current according to the preset theoretical current formula I calc =V test / R 补 , calculate the corresponding theoretical current value, where I calc is the theoretical current value, V test is the test voltage, R 补 is the compensation resistance data.

[0081] Specifically, after applying the test voltage, due to changes in actual temperature and differences in heating tape materials, in order to make the calculated theoretical current value more accurate, the theoretical current value of the heating tape is calculated based on the compensation resistance data calculated in the previous steps. The calculation is based on Ohm's law, and the theoretical current value is used as an ideal value of the current response for subsequent current response comparisons.

[0082] S33: If the deviation between the current response and the theoretical current value exceeds a preset deviation range, and / or the current response exceeds a preset safety current threshold, it is determined that an electrical fault area exists in the heating tape.

[0083] Specifically, in each test stage, the software will calculate the deviation between the actual current response and the theoretical current value. If the deviation exceeds the preset tolerance range, or the current response exceeds the safe current threshold, the system will determine that there is an electrical fault area in the heating tape. The location and type of the fault area will be located through current data analysis and a fault diagnosis report will be generated. The report includes the specific fault location and possible causes of the fault, providing a basis for subsequent maintenance.

[0084] In one embodiment, if Figure 4 As shown, in step S40, a corresponding thermal curve is drawn according to the surface temperature change, and based on the thermal curve, it is confirmed whether there is thermal unevenness in the heating belt, which specifically includes:

[0085] S41: Real-time monitoring of temperature data of multiple preset positions on the surface of the heating tape, and obtaining surface temperature changes based on the temperature data, thereby generating a thermal curve graph.

[0086] Specifically, during the thermal performance test, temperature data from different positions on the surface of the heating tape is collected in real time through multiple temperature sensor arrays. These sensors are distributed in different areas of the heating tape to ensure the comprehensiveness and accuracy of the test results, and a thermal curve graph is generated based on the collected temperature data. The graph shows the temperature changes of the heating tape after power is turned on, and the real-time nature of the thermal performance data is ensured by updating the graph in real time.

[0087] S42: Based on the thermal curve, and through the formula The thermal uniformity index of the heating tape is calculated, where H is the thermal uniformity index, n is the number of preset positions, Ti is the temperature data of the i-th position, is the average temperature of the heating belt.

[0088] Specifically, the thermal uniformity index is calculated by using the temperature data at different locations in the thermal curve. This formula quantifies the uniformity of the temperature distribution on the heating cable surface by calculating the temperature deviation at each location. Assuming that the temperatures of the n temperature measurement points are close to the average temperature, the thermal uniformity index H will be very small, indicating that the surface temperature distribution of the heating cable is relatively uniform and in good working condition. If the temperature of some measurement points deviates significantly from the average temperature, the H value increases, indicating that the heating cable may have local overheating or heat loss, which may affect the performance of the heating cable or cause failure.

[0089] S43: Calculate the maximum temperature difference of the heating belt according to the thermal curve diagram. If the thermal uniformity index and / or the maximum temperature difference exceeds the corresponding preset threshold value, it is determined that the heating belt has thermal non-uniformity.

[0090] Specifically, during the calculation process, the temperature difference between the two points with the largest temperature change in the thermal curve is calculated. The temperature difference value is used to determine whether the temperature of the surface of the heating belt is uniform. If the calculated maximum temperature difference exceeds the preset safety range, or the thermal uniformity index also exceeds the set threshold, it indicates that there is thermal unevenness in the heating belt. The system will trigger an alarm and generate thermal performance test results.

[0091] In one embodiment, if Figure 5 As shown, in step S50, a standard test report is generated according to the insulation test results, the voltage resistance test results and the thermal performance test results, which specifically includes:

[0092] S51: Perform fault diagnosis and analysis based on the insulation test results, voltage resistance test results, thermal performance test results and corresponding test processes, and sort out the fault problems corresponding to different test processes.

[0093] Specifically, based on the results of previous tests, the test data of each process is analyzed and integrated to generate a fault diagnosis report. The report will list the problems and test results of each test process, such as whether there is current leakage, whether there is an electrical fault area, and whether there is thermal unevenness. All abnormal conditions detected will be summarized and detailed fault location will be provided to help operators quickly identify problems with the equipment.

[0094] S52: Perform targeted improvement analysis based on the fault problem to obtain corresponding operation suggestions, and then generate a standard test report based on different test results, test processes, fault problems and operation suggestions.

[0095] Specifically, on the basis of fault diagnosis, each fault problem is analyzed to determine its severity and generate targeted improvement suggestions. For example, if current leakage is detected, it may be recommended to replace the insulation layer of the heating tape. If the heat is uneven, it is recommended to check the heat source distribution of the heating tape. Finally, the report will generate a complete inspection report based on the fault problems and suggestions and output it.

[0096] In one embodiment, if Figure 6 As shown, the integrated heating cable power-on test detection method also includes:

[0097] S60: Obtain historical operating data and analyze the long-term operating status of the heating cable based on the historical operating data to identify potential failure modes and performance degradation trends.

[0098] Specifically, the historical operating data of the heating tape is obtained and analyzed, including multi-dimensional information such as temperature, current, and voltage. Based on the historical operating data, failure modes and performance degradation trends in long-term operation are identified, such as the gradual increase in equipment temperature or unstable current fluctuations. These problems are automatically marked and recorded for reference by subsequent maintenance personnel.

[0099] S70: Use time series analysis algorithms to predict future failure risks and equipment performance degradation of the heating cables based on failure modes and performance degradation trends, and then generate potential failure warning reports based on the prediction results.

[0100] Specifically, historical data is analyzed through a time series analysis algorithm, and combined with failure modes and performance degradation trends, the future failure risks and equipment performance degradation of the heating cables are predicted. Through regression analysis, machine learning and other methods, a potential failure warning report is generated, which lists in detail the expected failure time, failure type and preventive measures, to help users perform equipment maintenance in advance and avoid sudden failures.

[0101] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
