The invention provides a burn-in detection system which can be used for burning different types of power modules by replacing adapting plates, back plates and load plates. The adapting plates enable loads on the load plates to be loaded on objects to be detected through the back plates. An AD collector collects voltage data of the objects to be detected through the adapting plates and sends the data to a single-chip microcomputer. A temperature and humidity collector collects temperature and humidity data of the load plates and sends the data to the single-chip microcomputer. The single-chip microcomputer carries out signal processing on the received temperature and humidity data and the received voltage data to obtain a monitoring result and transmits the result to a display for displaying. In addition, the warning range of the monitoring result is set, and when the result is detected to exceed the warning range, warning inductions are sent out to trigger an alarm. According to the burn-in detection system, manual detection methods before the burn-in detection system is applied are replaced, and efficiency is improved greatly; in addition, the loads can be replaced freely according to needs; voltage signal self-testing and load inner temperature self-testing are added, and the system can give out an alarm immediately when faults happen; human resources are relieved, and uncertain factors caused by manual interference are avoided.
