[0001] This invention relates to the field of power supply testing technology, specifically a power supply aging test system. Background Technology

[0002] Before a power supply leaves the factory, it needs to undergo rigorous testing, one of which is aging testing. This test simulates the current, voltage, and other parameters of the power supply in its real working environment, and performs long-term continuous operation tests to verify the reliability of the power supply product under extreme conditions. This allows for the early detection of defects in the power supply product and improves the product's quality and stability. A power supply aging test system is usually required during the aging test process.

This preset data includes test parameters, environmental setting parameters, abnormal information, early warning information, and early warning thresholds. Based on the loaded preset data, the control module sends test parameters to the load module to control the test load conditions and sends environmental setting parameters to the environmental simulation module to control the test environmental conditions. Second, executing the test and acquiring data: The control module starts the test process. The load module simulates the actual working load according to the received test parameters. The environmental simulation module simulates the required environmental conditions. The data acquisition module monitors the data in real time through voltage sensors, current sensors, and temperature sensors. The power supply's operating parameters, such as output voltage, output current, and power supply temperature, are converted into digital signals by the data acquisition card and transmitted to the control module. The control module monitors the test data in real time and compares it with the warning threshold. Once an anomaly is detected, a warning message is immediately issued through the warning module. The warning message is conveyed through audible and visual alarms, SMS notifications, and email notifications. In the third step, all test data, logs, and warning messages are recorded and stored in the data management module to ensure data integrity and traceability. The communication interface module exchanges data with external devices as needed, acquiring data and commands from external devices, or sending test data, logs, and preset data to external devices. Based on the collected test data, the control module analyzes key performance indicators of the power supply, such as output stability, efficiency degradation, and weakened heat dissipation capacity. Based on the test data analysis results, the control module generates a report containing test data and analysis results. This report is stored in the data management module for subsequent quality control and product improvement reference.
