Specifically, the step S42 may include:

s421, when the test control unit recognizes that the switch unit is at the high level, it determines whether the power-on signal and the power-on signal of the device under test are received.

The boot signal is used to represent whether the device under test completes the boot process, for example, when the BMC outputs a 1Hz pulse, it represents that the device under test completes the boot process. The power-on signal is used for representing whether the device to be tested completes the power-on process, for example, when the CPLD outputs a high level, the device to be tested completes the power-on process.

When the test control unit identifies that the switch unit is arranged at a high level, the fatigue machine executes AC power-on and power-off tests, and at the moment, the fatigue machine can judge whether the high levels of the 1Hz pulse and the CPLD from the BMC to be tested are received at the same time through the ISP. When the power-on signal and the power-on signal of the device to be tested are received, step S422 is executed, otherwise step S425 is executed.

And S422, cutting off the running voltage and the standby voltage of the controllable unit, and controlling the controllable unit to be electrified again after delaying for a first preset time.

When receiving a starting signal and a power-on signal of the device to be tested, the fatigue machine can cut off the operating voltage and the standby voltage of the controllable unit. Taking the power-on and power-off test system of the device shown in fig. 6 as an example, when the test control unit ISP of the fatigue machine receives the power-on signal and the power-on signal of the device to be tested, the test control unit ISP can control EFUSE1, EFUSE2, EFUSE3 and EFUSE4 to power off, and power on again after the power off is performed for the first preset time period, so as to ensure that the device to be tested is powered on after all power off is completed.

And S424, outputting an alarm signal, wherein the alarm signal is used for detecting whether the fatigue machine is normal.

When the power supply signal of the controllable unit is abnormal, namely the PWRGD signal of the controllable unit is not pulled high, the fatigue machine can output an alarm signal at the moment, and the alarm device gives an alarm. Meanwhile, the fatigue machine is powered off, so that a tester can detect the running state of the fatigue machine, and the tester can take maintenance measures in time when finding the fault of the fatigue machine.

And S425, judging whether the starting signal and the power-on signal of the device to be tested are received within a second preset time length.

When the fatigue machine does not receive the start-up signal and the power-on signal of the device to be tested simultaneously, the fatigue machine can wait for a second preset time period, and judge whether the start-up signal and the power-on signal of the device to be tested are received within the second preset time period, when the start-up signal and the power-on signal of the device to be tested are not received within the second preset time period, the step S426 is executed, otherwise, the normal start-up of the device to be tested is indicated, and the subsequent power-on and power-off test process is continuously executed.

And S426, detecting the running state of the equipment to be tested.

When the power-on signal and the power-on signal of the device to be tested are not received within the second preset time length, the device to be tested is indicated to be not normally powered on, and the fatigue machine can control the device to be tested to be powered off and cut off the power supply of the device to be tested, so that a tester can check the running state of the device to be tested in time and determine whether the device to be tested is abnormal or not.

S427, the process returns to step S421.

When the power supply signal of the controllable unit is normal, it indicates that the fatigue machine is successfully powered on, and at this time, the fatigue machine may return to step S421, and repeat the above steps, so as to implement a cycle test of power on and power off of the AC.

Specifically, the step S42 may further include:

For the detailed description of the power-on signal and the power-on signal, reference is made to the related description of the above embodiments, and details are not repeated here. When the test control unit identifies that the switch unit is arranged at a low level, the fatigue machine executes DC power-on and power-off tests, and at the moment, the fatigue machine can judge whether the 1Hz pulse and the CPLD high level from the BMC to be tested are received at the same time through the test control unit ISP. When a power-on signal and a power-on signal of the device to be tested are received, step S401 is executed, otherwise step S404 is executed.

S401, cutting off the operating voltage of the controllable unit, and controlling the controllable unit to be electrified again after delaying for a third preset time.

When receiving a starting signal and a power-on signal of the device to be tested, the fatigue machine can cut off the operating voltage of the controllable unit. Taking the power-on and power-off test system of the device shown in fig. 6 as an example, when the test control unit ISP of the fatigue machine receives the power-on signal and the power-on signal of the device to be tested, the test control unit ISP can control EFUSE1 and EFUSE3 to power off, and power on again after the power off is performed for a second preset time period, so as to ensure that the device to be tested is powered on after all power off is completed. The second preset time period may be 20s or 30s, and is not specifically limited herein, and a person skilled in the art may determine the second preset time period according to a discharge experience value of the device to be tested.
