Problems solved by technology

However, after a power-on failure, the AC power supply will continue to supply power to the computer or server for the next time, and the staff cannot observe the phenomenon of this power-on failure, nor can they know the reason for this power-on failure
In addition, in order to ensure that the computer or server has enough time to start normally, the power-on duration of the AC power supply is often set to be relatively long, so that the efficiency of the cycle power-on test is relatively low

Abstract

The invention relates to a circularly electrifying test device. The circularly electrifying test device comprises a sampling circuit, a control circuit and a power supply circuit, wherein the first end of the sampling circuit is connected with a first interface; the first end of the control circuit is connected with the second end of the sampling circuit; the first end of the power supply circuit is connected with the third end of the control circuit; the second end of the power supply circuit is connected with an external alternating current; and the third end of the power supply circuit is connected with a power supply. The circularly electrifying test device controls the power supply circuit to switch on or off the connection of the power supply and the external alternating current through the sampling circuit and the control circuit so as to realize the circularly electrifying test and observe a phenomenon during incomplete power-on or failed power-off.

Description

technical field [0001] The invention relates to a cycle power-on test device. Background technique [0002] In the reliability test of the computer or server, there is a power-on cycle test project, which simulates the connection and shutdown of the mains power to make the computer or server power on and off, so as to verify the power-on success rate of the computer or server. In the power-on cycle test, the power-on duration, power-off duration, and cycle times of an AC power supply are generally set so that the AC power supply intermittently and cyclically supplies power to the computer or server. The computer or server is turned on during the power-on duration and enters an operating system, and then the operating system invokes a shutdown command to shut down the computer or server. After the computer or server is shut down, the AC power supply enters into a power-off duration. Then judge whether the computer or server is qualified according to the number of times that...
