The target device in this embodiment includes, but is not limited to, a chassis, a display.
Alternatively, the power module real-time current may be read through the control card bus.
Optionally, a power reading module may be disposed on the power module for obtaining the power module current.
In one embodiment, as shown in fig. 4, step 203 may include the following steps 2031 to 2032.
For example, the total board current may be subtracted from the obtained power module current to obtain a difference therebetween.
Optionally, the overcurrent threshold may be determined according to the current total board current.
For example, the determining the overcurrent threshold according to the current board total current may include: and obtaining the current of a single board card, calculating the ratio of the current of the single board card to the total current of the board card, and determining the overcurrent threshold according to the ratio.
Optionally, a single board current may be obtained through the control card.

Optionally, if the total current of the board card is not matched with the current of the power supply module, an alarm signal is output.
Alternatively, the alarm signal may be output by the control card.
Alternatively, the alarm signal may be output to a server, a terminal, a display or a signal lamp connected to the target device, an alarm, or the like. The specific output equipment needs to be determined according to actual conditions, and the specific output equipment and the specific output mode are not limited in the application.
Optionally, different target devices may have different determination conditions, and the output current of the power supply module is equal to the total output current of the board card within a certain range.
In one embodiment, if the total board current matches the power module current, updating the overcurrent threshold according to board variation includes: detecting whether the number of the board cards changes or not; and if the change of the number of the board cards is detected, updating the overcurrent threshold value.
Optionally, the number of boards can be detected through the control card. When the number of the board cards changes, the real-time current of the board cards is acquired.
Illustratively, as shown in fig. 2, the control card reads the current of the service card through the IIC Bus, reads the current output by the AC/DC (Alternating current-Direct current) Power module through the PMBUS (Power Management Bus) in real time, sends an alarm signal to the server through the internet access when the current output by the PMBUS and the current output by the PMBUS do not match, and sets the overcurrent threshold of the AC/DC Power module when the current output by the PMBUS and the PMBUS do not match.
Specifically, when a new service card is inserted or a service card is replaced, the control card is set to scan the board card in the chassis every 0.5s according to the time interval of the continuous operation step. When the service card is inserted, the control card reads the type of the newly added card through the IIC, reads the current of the card, and recalculates the total current of the card in the case. When the service card is pulled out, the control card can also detect the operation through the IIC and renew the total current of the board card in the computer box. And after the control card detects the plugging operation, the control card can read the real-time output current of the AC/DC power supply module, compare the real-time output current with the total current of the board card in the case, and update the overcurrent threshold of the power supply module according to the comparison result.
Optionally, for a chassis that does not support hot plugging, after power off, a service card is inserted or replaced, and when the chassis is powered on again, the control card reads the real-time output current of the AC/DC power module, compares the real-time output current with the total current of the board cards in the chassis, and then updates the overcurrent threshold of the power module according to the comparison result.
Optionally, when a plurality of power modules exist in the enclosure, each power module averages output current according to its own mechanism, and accordingly, each power module simultaneously sets the current source overcurrent threshold by the above method.
The method provided by the embodiment of the application can adjust the overcurrent threshold of the power module in real time according to the number of the board cards and the total current of the board cards in the case, so that the preset redundant current value of the power module is equivalent, when the board cards in the case are short-circuited with other parts (such as a back plate, a service card socket, a power socket, cables in the case and the like), the power module can be quickly triggered and enters an overcurrent protection or short-circuit protection state, the heat accumulated on the back plate, the socket and the cables in the case is reduced, and the case is prevented from being burnt.
