The voltage of the input heat source is precisely adjusted by the voltage regulator, and the input voltage and current of the heat source are monitored in real time by the voltage meter and the current meter, and the actual heating power is calculated and compared with the target power; the actual heating power is calculated by the following formula:

The recorded data is deeply mined and analyzed based on the built-in first deep learning model to evaluate the performance and stability of the heat source power control system.

[0047] The working principle of the above technical solution is as follows: when the heat source power control system is started, the hardware and software are first initialized, including checking the connection status of each hardware component and ensuring that the software program is loaded correctly. Parameters of key components (such as voltage stabilizer, voltage regulator, voltmeter, and ammeter) are calibrated. According to the test requirements, the target heating power of the heat source is set. The power value can simulate the heat loss of the traction converter under different working conditions, and the voltage input to the heat source is accurately adjusted by the voltage regulator to control the heating power of the heat source; the input voltage and current of the heat source are monitored in real time using the voltmeter and ammeter, the actual heating power is calculated, and compared with the target power. According to the real-time monitoring results, the voltage is fine-tuned through the control algorithm. The actual heating power gradually approaches and stabilizes within the target power range. Based on the machine learning algorithm, the historical data of the heat source power is learned and analyzed, and the power change trend in the future (such as the next week) is predicted. According to the real-time changes in the heat source power, the voltage regulation strategy is dynamically adjusted. For example, in the case of large power fluctuations, the frequency and amplitude of the voltage regulation are increased to ensure the consistency between the actual power and the target power. An overheat protection device is set in the heat source power control system. When the actual power exceeds the set threshold, the heat source power supply is automatically cut off to prevent equipment damage or safety accidents. At the same time, the alarm device is used to remind the operator to pay attention. The integrated fault self-diagnosis function monitors the working status of each component in real time. If an abnormality is found, the fault is located and the alarm is issued. During the test, the changes in key parameters, as well as the operating status and fault information of the system are recorded in real time. The key parameters include heat source power, voltage, and current. The recorded data is deeply mined and analyzed based on the built-in first deep learning model. Through the processing and analysis of the data, the performance and stability of the heat source power control system can be evaluated, providing a basis for subsequent improvement and optimization.

[0048] The effects of the above technical scheme are as follows: by accurately adjusting the voltage of the input heat source, the heat source heating power can be precisely controlled, ensuring the accuracy and reliability of the test results; improving the accuracy of the test data, and providing strong support for the performance evaluation and optimization of the water cooling system; the voltage regulation follows the principle of smoothness and stability, avoiding the impact of voltage mutation on the system, helping to protect the system hardware and extend the life of the equipment; reducing the failure rate of the system caused by voltage fluctuations, and improving the stability and reliability of the system; by real-time monitoring of the input voltage and current of the heat source, the actual heating power can be calculated and compared with the target power. According to the comparison results, the voltage is fine-tuned through the control algorithm, so that the actual heating power gradually approaches and stabilizes within the target power range; the real-time tracking and precise control of the heat source power are realized, ensuring the stability and accuracy of the test process; using the machine learning algorithm to learn and analyze the historical data of the heat source power, the power change trend in the future can be predicted; providing a basis for dynamically adjusting the voltage regulation strategy, helping to respond to possible power fluctuations in advance and ensure the consistency of the actual power with the target power; dynamically adjusting the voltage regulation strategy according to the real-time changes in the heat source power. For example, in the case of large power fluctuations, the frequency and amplitude of voltage regulation are increased; the response speed and regulation accuracy of the system to power fluctuations are improved, ensuring the stability and reliability of the test process; an overheating protection device and an integrated fault self-diagnosis function are set up to monitor the working status of each component in real time, and take measures to protect it when an abnormality occurs; effectively prevent equipment damage or safety accidents caused by overheating or failure, and improve the safety and reliability of the system; record the changes in key parameters in real time, as well as the operating status and fault information of the system, and conduct in-depth mining and analysis of the recorded data based on the built-in first deep learning model; provide strong support for the performance and stability evaluation of the heat source power control system, help to discover potential problems and optimize and improve. At the same time, it also provides valuable data resources for subsequent experiments and research. The above formula calculates the average power by sampling data from multiple points, which can more accurately reflect the actual power consumption. Compared with relying only on measurements at a single moment, this method is more representative of the power consumption under actual working conditions. The formula is based on sampling, so it can adapt to various load types (such as resistive, inductive or capacitive loads) and can be used for different power supply types (such as DC or AC power); when used in conjunction with an appropriate control algorithm, this method can dynamically adjust the input voltage so that the actual heating power remains near the target power. Through continuous sampling and calculation, real-time monitoring of power output can be achieved. The use of the above formula can improve the accuracy and response speed of the power control system, and can also provide valuable data support for system optimization.

[0049] In one embodiment of the present invention, the voltage is fine-tuned by a control algorithm according to the real-time monitoring result so that the actual heating power gradually approaches and stabilizes within the target power range; including: Preprocess the voltage and current data monitored in real time by the voltmeter and ammeter, calculate the actual heating power in real time based on the preprocessed voltage and current data, and compare it with the preset target heating power to obtain the power error; According to the size and change trend of power error, the control strategy is selected, and the parameters of the control strategy are dynamically adjusted using genetic algorithm; Based on the selected control strategy and optimized parameters, the voltage of the input heat source is fine-tuned through the voltage regulator; during the fine-tuning process, the power error is continuously monitored through the real-time feedback mechanism, and the fine-tuning amplitude and frequency are dynamically adjusted according to the error changes; After the voltage is fine-tuned, a period of stability verification is carried out to verify whether the actual power fluctuates stably within the target power range; if there is a deviation, the control parameters are further fine-tuned according to the verification results to form a closed-loop feedback control.

[0050] The working principle of the above technical solution is as follows: first, the voltage and current data monitored in real time by the voltmeter and the ammeter are collected, and the data contains noise or abnormal values ​​and needs to be preprocessed; based on the preprocessed voltage and current data, the actual heating power is calculated in real time using the power calculation formula; the calculated actual heating power is compared with the preset target heating power to obtain the power error, and the error value reflects the difference between the current actual power and the target power; according to the size and change trend of the power error, the appropriate control strategy is selected. For example, when the error is large and changes rapidly, the PID (proportional-integral-differential) control with a faster response speed may be selected; when the system is highly nonlinear, fuzzy control may be selected; when the system parameters are time-varying, adaptive control may be selected; and optimization methods such as genetic algorithms are used to dynamically adjust the parameters of the selected control strategy. Genetic algorithms optimize control performance by simulating natural selection and genetic mechanisms to search for the optimal solution in the parameter space; based on the selected control strategy and optimized parameters, the voltage of the input heat source is fine-tuned through the voltage regulator. The goal of fine-tuning is to reduce the power error so that the actual power gradually approaches the target power; during the fine-tuning process, the power error is continuously monitored through a real-time feedback mechanism. If the error is still large, continue to adjust the voltage; if the error is reduced to an acceptable range, maintain the current voltage value; dynamically adjust the fine-tuning amplitude and frequency according to the error change. If the error decreases rapidly, the fine-tuning amplitude and frequency can be appropriately reduced; if the error changes slowly or fluctuates greatly, it may be necessary to increase the fine-tuning amplitude and frequency; after the voltage is fine-tuned, a period of stability verification is performed to ensure that the actual power fluctuates stably within the target power range without excessive deviation or instability; if the stability verification results show that there is a deviation, the control parameters are further fine-tuned according to the verification results. This process forms a closed-loop feedback control system, which is continuously iterated and adjusted until the predetermined stability and accuracy requirements are met.
