Description

Server power performance monitoring method and device and computer equipment

Technical Field

The present application relates to the technical field of server power supplies, and in particular, to a method, an apparatus, and a computer device for monitoring server power supply performance.

Background

With the rapid development of network technology, different types of servers are emerging. When the server system is constructed, the power supply plays a decisive role in the overall operation of the server system, and if the power supply fails, the server cannot normally operate.

A large number of Buck voltage reduction circuits are used in a server power supply to obtain various voltages, so that the power supply requirements of different equipment are met. The output filter inductor and the filter capacitor in the Buck voltage reduction circuit are indispensable and are usually used as a DC-DC converter, so that the detection of the states of the output filter inductor and the filter capacitor of the DC-DC converter in the operation process of the server plays a decisive role in the quality of output electric energy.

The effective value of the output voltage of the power supply of the server, the voltage ripple, the effective inductive current and the performance of the inductive current ripple are currently in an open loop state, the effective value and the ripple of the output voltage of the power supply are only tested when the project is established, the performance of the output voltage is ensured by improving the consistency of components, and the performance of the output voltage of the server cannot be monitored after batch production.

The existing server power supply does not monitor the output capacitor voltage and the output inductive current, and the states of the output capacitor voltage and the output inductive current cannot be known. If output capacitor voltage, output inductive current are unusual, will influence server power supply quality, can lead to burning the board risk when serious. The output capacitor voltage ripple is too large, which may cause the maximum value and the minimum value of the output ripple voltage to exceed the power supply requirement of the back-end device (e.g., CPU, PCH), affect the normal operation of the back-end device (e.g., CPU, PCH), and even cause the damage of the back-end device.

After the server runs for a long time, the quality of output electric energy can be changed due to the aging of devices and the change of external environment. Because the output capacitor voltage and the output inductor current are not monitored at present, the states of the output capacitor voltage and the output inductor current cannot be known, and the output capacitor voltage ripple is too large to cause damage to back-end equipment (such as a CPU and a PCH). In addition, the induction current ripple is too large, so that the induction heating is damaged, the normal operation of the server is influenced, and even the risk of burning the board is caused.

Therefore, the monitoring and alarming of the voltage of the output capacitor and the current performance of the inductor of the power supply of the server are urgently needed, the voltage ripple and the effective value of the output capacitor and the current ripple and the effective value of the output inductor are monitored in time, and the reliability of the power supply is maintained, so that the power supply quality of the power supply of the server is ensured, and the stable and reliable operation of the server is ensured.

In summary, the server power performance monitoring apparatus 10 is composed of a signal acquisition module 1, a control policy module 2, and a protection execution module 3. The signal acquisition module 1 includes a first high-speed analog-to-digital converter 11 and a second high-speed analog-to-digital converter 12, the control policy module 2 is preferably a DSP control system (hereinafter referred to as DSP), and the protection execution module 3 includes a baseboard management controller BMC to describe a specific use manner.

1) The signal acquisition module 1:

a double-channel high-speed analog-to-digital converter is adopted to simultaneously acquire a voltage signal and a current signal. The first high-speed analog-to-digital converter 11 acquires a capacitor voltage signal in real time through an output resistor with an output capacitor connected in parallel, and the second high-speed analog-to-digital converter 12 acquires a current signal in real time through a precision resistor with an inductor connected in series and converts the current signal into a digital signal. And transmitting the acquired digital voltage signal and digital current signal to the DSP through the SPI serial interface.

2) The control strategy module 2:

the DSP calculates the voltage effective value and the voltage ripple within the switching period T1 from the voltage signal transmitted from the first high-speed analog-to-digital converter 11, and calculates an average value for a plurality of times (e.g., N1 times) to obtain the voltage effective value and the voltage ripple. The DSP calculates the current effective value and the current ripple in the switching period T1 from the current signal transmitted from the second high-speed analog-to-digital converter 12, and calculates an average value for a plurality of times (e.g., N1 times) to obtain the current effective value and the current ripple.

And the DSP stores the calculated voltage effective value, voltage ripple, current effective value and current ripple into a register. If the voltage effective value, the voltage ripple and the current ripple exceed the alarm value, adding 1 to a first counter A; the second counter B is incremented by 1 if the risk value is exceeded.

The DSP calculates the values of a first counter A and a second counter B within the time T2. If the first counter A counts to A100 within the time T2, an alarm signal is sent out, otherwise, the first counter A is cleared; and if the second counter B counts to B100 within the time T2, sending a risk signal, otherwise, clearing the second counter B.

When the alarm signal and the risk signal are sent out, the DSP sends the alarm signal and the risk signal to the BMC through I2C communication, and simultaneously sends a voltage effective value, a voltage ripple, a current effective value and a current ripple to the BMC to remind a user of carrying out corresponding operation.

When an alarm signal is sent out, reminding a user that the corresponding board should be replaced in time; when sending the risk signal, in time cut off server power supply, prevent because of the too big burning board risk that leads to of voltage ripple, electric current ripple.

3) The protection execution module 3:

when the BMC receives the alarm signal sent by the DSP, the BMC informs a user of replacing the corresponding board in time, and displays the voltage effective value, the voltage ripple, the current effective value and the current ripple as the basis for evaluating the voltage and current performance by the user.

When the BMC receives the risk signal sent by the DSP, the power supply of the server is immediately cut off through the enabling signal, and the risk of baking the motherboard is avoided.

When the method is used specifically, the technical scheme of the application comprises the following specific implementation steps:

1) The first high-speed analog-to-digital converter 11 and the second high-speed analog-to-digital converter 12 are 14-bit, 3GSPS analog-to-digital converters (ADCs) using a dual-channel high-speed converter AD9208 of ADI. The device has an on-chip buffer and a sample-and-hold circuit, ensuring lower power consumption, smaller package size, and excellent ease of use. And sending the converted digital voltage signal and digital current signal to the DSP through SPI communication.

2) The control strategy module 2 adopts C64xx series DSP of TI company as a core processor, the working main frequency of the core processor reaches 1000MHz, the digital voltage signal and the digital current signal transmitted by the high-speed analog-to-digital converter AD9208 are received in real time, and a voltage effective value, a voltage ripple, a current effective value and a current ripple are calculated. If the voltage effective value, the voltage ripple and the current ripple exceed the alarm value, adding 1 to a first counter A; the second counter B is incremented by 1 if the risk value is exceeded. And determining whether to trigger the alarm signal and the risk signal by judging whether the first counter A and the second counter B reach the set values within the time T2. When the alarm signal and the risk signal are sent out, the DSP sends the alarm signal and the risk signal to the BMC through I2C communication, and simultaneously sends a voltage effective value, a voltage ripple, a current effective value and a current ripple to the BMC to remind a user of carrying out corresponding operation.

The protection execution module 3 adopts a BMC system of the server, when the BMC receives the alarm signal sent by the DSP, the BMC informs a user of replacing a corresponding board in time, and displays a voltage effective value, a voltage ripple, a current effective value and a current ripple as a basis for evaluating the voltage and current performance of the user. When the BMC receives the risk signal sent by the DSP, the power supply of the server is immediately cut off through the enabling signal, and the risk of baking the motherboard is avoided.

Therefore, the problem that the rear-end power supply device is damaged due to the fact that output voltage is abnormal and output voltage ripples are overlarge can be solved, the risk of burning the board is reduced, and the running performance of the server is improved. Secondly, the problem that the ripple current of the inductor is too large due to some unpredictable factors can be solved, the risk of burning the board due to serious heating of the inductor is avoided, and the running performance of the server is improved.

Among the above-mentioned server power performance monitoring device, through server power output capacitor voltage, inductive current performance control, in time know output capacitor voltage and inductive current's performance to in time make the protection according to output capacitor voltage and inductive current's performance, avoid crossing CPU, the PCH damage that leads to because of the output voltage performance hangs down, burn the board risk even.
