Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a method, device, equipment and medium for controlling a server power supply. Background Art

[0002] The server power supply is the power supply unit of the server. Ensuring that the server power supply starts up normally and enters a stable operating state is particularly important for the normal and reliable operation of the server. For the power-on control of the server power supply, a current transformer is usually connected in series with the server power supply. The output current of the server power supply is detected by the current transformer, and then the hardware circuit controls the server power supply according to the output current of the server power supply. However, detecting current through a current transformer and controlling the server power supply through a hardware circuit will cause the internal space of the server power supply to be occupied and the cost to increase, and it has limitations. When the server power supply is turned on with a capacitive load, it is easy to mistakenly judge that the server power supply output is short-circuited, which leads to control errors. Therefore, how to solve the above technical defects has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0069] The core of the present invention is to provide a control method for a server power supply, which can reduce the space occupied and cost inside the server power supply, and can accurately judge and control when the server power supply is turned on with a capacitive load.

[0070] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0071] Please refer to Figure 1 , Figure 1 A flow chart of a method for controlling a server power supply according to an embodiment of the present invention is provided. Figure 1 As shown, the method includes:

[0072] S101: Obtain the output current of a server power supply during startup to obtain a first current.

[0073] The server power supply control method provided in this embodiment may be executed by a microcontroller, which obtains the output current of the server power supply and analyzes the output current of the server power supply to control the server power supply.

[0074] In some embodiments, obtaining the output current of the server power supply includes:

[0075] Obtaining a voltage across a sampling resistor at an output end of the server power supply;

[0076] The output current of the server power supply is obtained according to the voltage across the sampling resistor and the resistance value of the sampling resistor.

[0077] refer to Figure 2As shown, a sampling resistor is connected in series between the output of the server power supply and the load. The microserver performs voltage sampling and calculation functions. The microserver obtains the voltage across the sampling resistor. The voltage at one end of the sampling resistor is denoted as V1, and the voltage at the other end is denoted as V2. The resistance of the sampling resistor is denoted as R. The output current of the server power supply, I, is calculated as |V1 - V2| / R. Replacing a current transformer with a sampling resistor effectively reduces the internal space occupied by the server power supply and reduces the cost of the server power supply.

[0078] To prevent inaccurate single sampling results from affecting control accuracy, in some embodiments, the microcontroller samples the voltage across the sampling resistor multiple times, takes an average of the multiple sampling results, and obtains the output current of the server power supply based on the average.

[0079] S102: Analyze the first current to determine whether the first current is overcurrent and whether the server power supply has an output short circuit.

[0080] In some embodiments, analyzing the first current to determine whether the first current is overcurrent and whether the server power supply has an output short circuit includes:

[0081] comparing the first current with a first preset threshold;

[0082] If the first current is less than the first preset threshold, the first current does not over-current;

[0083] If the first current is not less than the first preset threshold, the first current is overcurrent, and the first current is compared with the second preset threshold;

[0084] If the first current is less than the second preset threshold, the first current is overcurrent and the server power supply is not short-circuited;

[0085] If the first current is not less than the second preset threshold, comparing the first current with a third preset threshold;

[0086] If the first current is less than the third preset threshold, the first current is overcurrent and the server power supply is not short-circuited;

[0087] If the first current is not less than the third preset threshold, the server power output is short-circuited.

[0088] The first preset threshold value < the second preset threshold value < the third preset threshold value. Overcurrent refers to current exceeding the normal range. A short circuit in the server power supply output can cause overcurrent in the server power supply output. Starting up the server power supply with a capacitive load can also cause overcurrent in the server power supply output. The microcontroller compares the first current with the first preset threshold value. If the first current is less than the first preset threshold value, it indicates that the first current is within the normal range and not overcurrent. In this case, the server power supply starts up normally. If the first current is not less than the first preset threshold value, the microcontroller further compares the first current with the second preset threshold value. If the first current is less than the second preset threshold value, it indicates that, although the first current exceeds the normal range, it has not reached the overcurrent protection point, and the server power supply starts up normally. If the first current is not less than the second preset threshold value, the microcontroller further compares the first current with the third preset threshold value. If the first current is less than the third preset threshold value, it is determined that the server power supply output is in the state of starting up with a capacitive load and the server power supply is not short-circuited. Therefore, the server power supply starts up normally. If the first current is not less than the third preset threshold value, the server power supply output is determined to be short-circuited.

[0089] S103: If the first current is not overcurrent, control the server power supply to start up.

[0090] S104: If the first current is overcurrent and the server power supply is not short-circuited, the server power supply is controlled to power on, and the output current of the server power supply after powering on is obtained to obtain a second current, and the server power supply is controlled according to the second current.

[0091] S105: If the server power supply output is short-circuited, clamp the switching frequency of the server power supply and control the server power supply to shut down.

[0092] If the first current does not overcurrent, the server power supply starts up normally. If the first current overcurrent occurs but the server power supply is not short-circuited, the server power supply also starts up normally. After the server power supply starts up, the microcontroller obtains the output current of the server power supply after startup, obtains the second current, and controls the server power supply on and off based on the second current. If the server power supply output is short-circuited, the switching frequency of the server power supply is clamped to prevent damage to the power devices within the server power supply, and the server power supply is then shut down.

[0093] In some embodiments, controlling the server power supply according to the second current includes:

[0094] If the first current is not less than the first preset threshold but less than the second preset threshold, comparing the second current with the second preset threshold;

[0095] If the second current is less than the second preset threshold, keeping the server power supply in the power-on state;

[0096] If the second current is not less than the second preset threshold, controlling the server power supply to shut down;

[0097] If the first current is not less than the second preset threshold but less than the third preset threshold, comparing the second current with the third preset threshold;

[0098] If the second current is not less than the third preset threshold, controlling the server power supply to shut down;

[0099] If the second current is less than the third preset threshold, comparing the second current with the second preset threshold;

[0100] If the second current is less than the second preset threshold, keeping the server power supply in the power-on state;

[0101] If the second current is not less than the second preset threshold, the server power supply is controlled to shut down.

[0102] refer to Figure 3 As shown, when the first current is not less than the first preset threshold but less than the second preset threshold, after the server power supply is powered on, the second current is compared with the second preset threshold. If the second current is less than the second preset threshold, it indicates that the output current of the server power supply exceeds the normal range only during the server power supply startup process. In this case, the server power supply remains powered on and operates normally. If the second current is not less than the second preset threshold, it is considered that the server power supply is still in an overcurrent state after normal startup, and the server power supply is controlled to shut down. If the first current is not less than the second preset threshold but less than the third preset threshold, after the server power supply is powered on, the second current is compared with the third preset threshold. If the second current is not less than the third preset threshold, it is considered that the overcurrent during the server power supply startup process is due to startup with a capacitive load, and the second current is compared with the second preset threshold again. If the second current is less than the second preset threshold, it indicates that the output current of the server power supply exceeds the normal range only during the server power supply startup process and the overcurrent during startup is due to startup with a capacitive load. In this case, the server power supply remains powered on and operates normally. If the second current is not less than the second preset threshold, it is considered that the server power supply is still in an overcurrent state after being normally powered on, and the server power supply is controlled to be powered off.

[0103] In some embodiments, before controlling the server power supply to shut down, the method further includes:

[0104] Determine whether the number of detections reaches a preset value;

[0105] If reached, the server power is controlled to shut down;

[0106] If not, return to the step of obtaining the output current of the server power supply during startup to obtain the first current.

[0107] refer to Figure 3 As shown, to prevent abnormalities in the output current obtained in a single pass, the operation of clamping the switching frequency of the server power supply in steps S101 to S105 can be repeated. If the number of detections reaches a preset value, that is, the number of times the operation of clamping the switching frequency of the server power supply in steps S101 to S104 and S105 is repeated reaches a preset value, for example, three times, then a short circuit is determined in the server power supply output, and the server power supply is controlled to shut down.

[0108] In some embodiments, further comprising:

[0109] If the first current is overcurrent, an overcurrent alarm is reported, and the overcurrent alarm is canceled or an overcurrent fault is reported according to the second current.

[0110] When the first current is determined to be overcurrent, the microcontroller reports an overcurrent alarm. After the server power is turned on, the microcontroller cancels the overcurrent alarm or reports an overcurrent fault according to the second current.

[0111] In some embodiments, reporting an overcurrent alarm and canceling the overcurrent alarm or reporting an overcurrent fault according to the second current includes:

[0112] comparing the first current with a first preset threshold;

[0113] If the first current is not less than the first preset threshold, comparing the first current with a second preset threshold;

[0114] If the first current is less than the second preset threshold, an overcurrent alarm is reported, and after the server power is turned on, the second current is compared with the second preset threshold;

[0115] If the second current is less than the second preset threshold, canceling the overcurrent alarm;

[0116] If the second current is not less than the second preset threshold, reporting an overcurrent fault and controlling the server power supply to shut down;

[0117] If the first current is not less than the second preset threshold, comparing the first current with a third preset threshold;

[0118] If the first current is less than the third preset threshold, an overcurrent alarm is reported, and after the server power is turned on, the second current is compared with the third preset threshold;

[0119] If the second current is not less than the third preset threshold, reporting an overcurrent fault and controlling the server power supply to shut down;

[0120] If the second current is less than the third preset threshold, comparing the second current with the second preset threshold;

[0121] If the second current is less than the second preset threshold, canceling the overcurrent alarm;

[0122] If the second current is not less than the second preset threshold, reporting an overcurrent fault and controlling the server power supply to shut down;

[0123] If the first current is not less than the third preset threshold and the number of detections reaches a preset value, an overcurrent fault is reported and the server power supply is controlled to shut down.

[0124] refer to Figure 3 As shown, if the first current is less than the second preset threshold, an overcurrent alarm is reported, and the server power supply is controlled to start normally. After the server power supply is turned on, the second current is compared with the second preset threshold. If the second current is less than the second preset threshold, the overcurrent alarm is canceled, and the server power supply operates normally. If the second current is not less than the second preset threshold, an overcurrent fault is reported, and the server power supply is controlled to shut down.

[0125] If the first current is not less than the second preset threshold, the first current is compared with the third preset threshold. If the first current is less than the third preset threshold, an overcurrent alarm is reported and the server power supply is controlled to start normally. After the server power supply is turned on, the second current is compared with the third preset threshold. If the second current is not less than the third preset threshold, an overcurrent fault is reported and the server power supply is controlled to shut down. If the second current is less than the third preset threshold, the second current is compared with the second preset threshold again. If the second current is less than the second preset threshold, the overcurrent alarm is canceled and the server power supply operates normally. If the second current is not less than the second preset threshold, an overcurrent fault is reported and the server power supply is controlled to shut down. If the first current is not less than the third preset threshold and the number of detections reaches the preset value, an overcurrent fault is reported and the server power supply is controlled to shut down.

[0126] In summary, the server power supply control method provided by the present invention uses software control to control the server power supply. It also determines whether the server power supply output current is overcurrent or short-circuited. If the server power supply output current is overcurrent and the server power supply output is not short-circuited, the server power supply is controlled to start up normally. This ensures normal server power-up even if a capacitive load is connected to the output of the server power supply, causing an overcurrent during startup. In the event of a server power supply output short-circuit, the switching frequency of the server power supply is clamped and the server power supply is controlled to shut down, thereby preventing damage to the server power supply.
