Embodiment Construction

[0023] figure 1 It is a working principle diagram of the burn-in detection system of the present invention. In the figure, MSP430F149 single-chip microcomputer is used as the microcontroller. This single-chip microcomputer is at the core of the system and is used to receive the temperature and humidity data collected by the temperature and humidity collector and the voltage data collected by the AD collector. After signal processing, it will monitor The result is transferred to the display. And the monitoring data alarm range can be set through programming. If the monitored data exceeds the set range, the single chip computer will trigger an alarm command to the alarm. The single-chip microcomputer is equipped with a serial communication interface. After the level conversion of the single-chip microcomputer data, it communicates with the computer through the RS232 interface, and the computer can be used as a terminal device for related operations.

Abstract

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.

Description

technical field [0001] The invention belongs to the field of power supply testing, and in particular relates to a burn-in detection system. Background technique [0002] Power supply components have always been a necessary part of various test systems and test equipment, so the reliability of this component is the top priority of each system and equipment. Whether the reliability level can reach the design index needs to be verified by the reliability screening test. Burn-in screening test is the main item of reliability screening. Its purpose is to expose the working failure of the test piece to the maximum extent by applying appropriate temperature stress and electrical stress to the test piece. [0003] In mass production, due to the variety of power supply products and various interface forms, burn-in tests need to use a variety of test instruments and equipment, relying on manual construction of burn-in test platforms, manual timing tests, and manual recording of test ...
