Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two non-identical entities with the same name or different parameters, and it is understood that "first" and "second" are only used for convenience of expression and should not be construed as limiting the embodiments of the present invention. Furthermore, the terms "comprises" and "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements does not include all of the other steps or elements inherent in the list.
In order to realize the technical scheme of the invention, as shown in fig. 1, the power supply connection schematic diagram of the server is shown, and the power supply connection schematic diagram comprises a battery backup system BBS, a power module PSU, a power frame Powershelf and a copper bar Busbar, wherein the power module PSU outputs 12.6V, the power module PSU is connected to a cabinet copper bar through the power frame Powershelf, and the battery backup system BBS is connected to the copper bar through a wiring Clip (Clip). Fig. 2 is a schematic diagram of signal connection between the cabinet management unit PMC and the battery backup system BBS, where I2C is used for communication, and a discharge signal is used for controlling discharging and charging of the battery backup system BBS.
In brief, the key point of the present invention is to detect an input signal of the power module PSU, that is, a Vin _ OK signal, and determine the input signal through the cabinet management unit PMC and then transmit the signal to the battery backup system BBS to start discharging output, and when the battery backup system BBS outputs the signal, the power module PSU can still perform seamless power supply switching between the power module PSU and the battery backup system BBS within a hold time (hold), thereby eliminating a voltage drop risk generated by using voltage detection as a switching criterion.
Specifically, the present invention uses the discharge signal discharge as the discharge trigger signal, which can provide the battery backup system BBS with sufficient discharge response time. In order to ensure that the cabinet management unit PMC gives the discharge signal discharge most quickly, the cabinet management unit PMC is designed in a signal triggering interruption mode, namely, program interruption is triggered as long as the Vin _ OK signal level changes, and the cabinet management unit PMC enters a mode for processing the signal, so that the speed is greatly improved compared with the speed corresponding to the traditional mode that the cabinet management unit PMC polls the power supply module PSU.
In addition, the initial discharge voltage of the battery backup system BBS is slightly higher than the output voltage of the battery module PSU because the power module PSU can also output for a short period of time after the input of the cabinet is powered off. The output voltage of the battery backup system BBS is higher than that of the power supply module PSU, and at the moment, the copper bar is mainly powered by the battery backup system BBS, so that the voltage drop condition cannot occur. In addition, the battery backup system BBS outputs a discharge voltage that drops to a lower holding voltage after a predetermined duration, which is in particular lower than the output voltage of the power supply module PSU, so that the design can prevent the battery backup system BBS from discharging by mistake in some situations. Specifically, when only one path of power supply of the cabinet is abnormal, at this time, vin _ OK signals of all the power supply modules PSU are low levels, the discharge signal discharge is set, and at this time, the battery backup system BBS should discharge, but if the power supply module PSU in the dual input mode is adopted, the power supply module PSU itself can still normally work to supply power to the copper bar. In this case, it is not necessary for the battery backup system BBS to maintain a high discharge potential at all times. After a predetermined duration has elapsed, the battery backup system BBS continues to act as a backup, since the lower holding voltage is set, which is still supplied by the power supply module PSU.
To this end, in a first aspect of the present invention, a server power supply method 100 is provided. Fig. 3 shows a schematic flow chart of an embodiment of a server power supply method according to the present invention. In an embodiment as shown in fig. 3, the method comprises:
step S110: the power supply module PSU supplies power to the cabinet copper bar, and sets a voltage input flag bit signal Vin _ OK of each power supply module PSU to be a normal level or an abnormal level based on the state of a voltage input end of each power supply module PSU;
step S120: a cabinet management unit (PMC) monitors the voltage input flag bit signal Vin _ OK of each power module PSU;
step S130: in response to that the number of the voltage input flag bit signals Vin _ OK at the abnormal level exceeds a threshold value, the cabinet management unit PMC sets a discharge signal discharge to a working level and transmits the discharge signal discharge to a battery backup system BBS;
step S140: the battery backup system BBS starts discharging based on the received working level of the discharge signal discharge, wherein the backup output voltage is raised to a discharge voltage higher than the output voltage of the power supply module PSU to take over the power supply to the cabinet copper bar, and the backup output voltage is reduced to a sustain voltage lower than the output voltage of the power supply module PSU after a predetermined duration.
Firstly, under a normal working state, the power supply module PSU supplies power to the cabinet copper bar. At this time, in step S110, the voltage input flag signal Vin _ OK of each power module PSU is set to be a normal level or an abnormal level based on the voltage input terminal state of each power module PSU. Preferably, and as selected in subsequent embodiments, the normal level corresponds to a high level and the abnormal level corresponds to a low level. However, it is conceivable that the opposite arrangement is also possible.
Subsequently, in step S120, the cabinet management unit PMC monitors the voltage input flag signals Vin _ OK of the power modules PSU to count the number of the voltage input flag signals Vin _ OK at the normal level and the abnormal level, respectively.
When the number of the voltage input flag bit signals Vin _ OK at the abnormal level exceeds the threshold value, the cabinet management unit PMC sets the discharge signal discharge to an operating level, for example, a low level, and transmits the set discharge signal to the battery backup system BBS in step S130. Here, different thresholds may be set according to the number of power supply modules PSU in different power supply configurations. For example, for a configuration of preferably 6 power supply modules PSU, the threshold value may be set to 2 or 3 or higher. As another example, the threshold may be set lower, e.g. 1, for the structure of the dual battery module PSU. In addition, the setting of the threshold may also be adjusted accordingly, depending on the requirements for stability and reliability.
Finally, after the battery backup system BBS receives the operating level of the discharge signal discharge, the battery backup system BBS starts discharging based on the received operating level in step S140. Here, the backup output voltage of the battery backup system BBS is raised to a discharge voltage, which is higher than the output voltage of the power supply module PSU, so as to take over the power supply to the cabinet copper bar. After the preset duration, the backup output voltage is reduced to the holding voltage, and the holding voltage is lower than the holding voltage of the output voltage of the power supply module PSU, so that the battery backup system BBS returns the power supply of the cabinet copper bar to the battery module PSU to return to the backup position under the condition that the discharging is false triggering, and the power feeding caused by the over-discharging of the lithium battery of the battery backup system BBS is prevented.
In some embodiments of the server power method 100 according to the invention, the method further comprises:
step S150: responding to the electric quantity of the battery backup system BBS is lower than the preset lowest electric quantity, finishing discharging the battery backup system BBS, wherein stopping voltage output of the battery backup system BBS, finishing power supply of the cabinet copper bar.
Specifically, when the charge amount of the battery backup system BBS is lower than a preset minimum charge amount, for example, lower than 5%, the battery backup system BBS ends the discharge in step S150. Here, battery backup system BBS stops voltage output, finishes the power supply to the rack copper bar, consequently the rack copper bar will not supply power at this moment completely.
In some embodiments of the server power method 100 according to the invention, the method further comprises:
step S160: detecting the electric quantity of the battery backup system BBS in response to the discharge signal discharge being at a standby level;
step S170: in response to the electric quantity of the battery backup system BBS being less than the full electric quantity, the battery backup system BBS performs a charging operation until the electric quantity thereof reaches the full electric quantity.
Specifically, when the power supply is normal, the discharge signal discharge is at a standby level, for example, a high level, and the amount of power in the battery backup system BBS is detected in step S160. If the charge of the battery backup system BBS is less than the full charge, for example, less than 100%, preferably less than 95%, and further preferably less than 90%, in step S170, the battery backup system BBS performs a charging operation until the charge reaches the full charge. Therefore, when the battery backup system BBS is in a backup position, it is ensured that the battery backup system BBS maintains a high power level or even a full power level as much as possible.
In some embodiments of the server power supply method 100 according to the invention, the step S110 further comprises: each of the power modules is configured in a dual input power mode in which a normal operation input is performed by a first voltage input and is switched off to a second voltage input in response to the first voltage input. Specifically, the power supply module PSU in the dual-input power supply mode has two inputs, namely a first voltage input1 and a second voltage input2, and uses the first voltage input1 during normal operation, and when the first voltage input1 is powered off, the power supply module PSU is switched to the second voltage input2 to operate.
In some embodiments of the server power supply method 100 according to the invention, the step S110 further comprises: in response to a power supply abnormality occurring at one or both of the first voltage input and the second voltage input, setting a voltage input flag signal Vin _ OK of the power supply module PSU from a normal level to an abnormal level. That is, when a power supply abnormality occurs in one or both of the first voltage input and the second voltage input, the voltage input flag bit signal Vin _ OK of the power module PSU is set from a normal level to an abnormal level, for example, the voltage input flag bit signal Vin _ OK is changed from a high level indicating normal operation to a low level indicating abnormality.
Further, in some embodiments of the server power supply method 100 according to the present invention, the full load retention time of the dual input power supply mode is greater than 16 milliseconds, and the actual operational retention time of the dual input power supply mode is at least 2 times, or 5 times, or 10 times the full load retention time. The invention uses the discharge signal discharge as the discharge trigger signal, and can provide sufficient discharge reaction time for the battery backup system BBS. The dual input supply mode power supply module PSU typically has a hold time (hold) of more than 16ms at full load. Its actual working hold time is much longer than 16ms, at least 2 times, or 5 times, or even 10 times the full load hold time.
Furthermore, in some embodiments of the server power supply method 100 according to the invention, the time difference between the setting of the discharge signal discharge to the operating level and the start of the discharge of the battery backup system BBS is less than the full hold time of the dual input power supply mode. More preferably, the time difference between the setting of the discharge signal discharge to the operating level and the initiation of the discharge of the battery backup system BBS is less than half of the full-load holding time of the dual input supply mode, or less than one third of the full-load holding time of the dual input supply mode, or less than 5 milliseconds. In actual measurements according to some embodiments of the invention, for example in the aforementioned embodiments in which the full-load retention time is greater than 16ms, the time from the disconnection of the two inputs of the power supply module PSU to the start-up discharge of the battery backup system BBS is less than 5ms, much less than the full-load retention time of the dual-input power supply mode, even much less than half the full-load retention time, or less than one third of the full-load retention time of the dual-input power supply mode. Thereby, seamless handover is achieved.
In some embodiments of the server power supply method 100 according to the invention, the step S140 further comprises: the difference between the discharge voltage and the output voltage of the power supply module PSU is at most one hundredth, at least five thousandths of the output voltage of the power supply module PSU. The output voltage and the sustain voltage of the power supply module PSU are set to be at least one percent and at most three percent of the output voltage of the power supply module PSU. Taking the foregoing embodiment as an example, the output voltage of the power supply module PSU is preferably 12.6V. At this time, the discharge voltage of the battery backup system BBS is at most one hundredth, at least five thousandths higher than the output voltage of the power supply module PSU. In a preferred embodiment, the discharge voltage may be set to, for example, 12.7V, 12.65V, or the like. And the holding voltage of the battery backup system BBS is at least one percent, and at most three percent lower than the output voltage of the power supply module PSU. In a preferred embodiment, the sustain voltage may be set to, for example, 12.3V, 12.35V, 12.4V, etc.
Fig. 4 is a schematic flow chart illustrating charging and discharging control of the cabinet management unit PMC and the battery backup system BBS according to the present invention. The following description takes 6 dual-input power modules PSU as an example. Firstly, two inputs of the dual-input power module PSU normally work at input1, when the input1 is powered off, the operation is switched to input2, and if the two inputs are powered on normally, a Vin _ OK signal corresponding to the power module PSU is at a high level. When one input power supply is abnormal or both input power supply are abnormal, the corresponding Vin _ OK is in a low level. As shown in fig. 4, the cabinet management unit PMC continuously detects Vin _ OK signals of 6 power modules PSU, and when the number of low levels is greater than 2, it indicates that at least 3 power modules PSU are abnormal in power input and supply, at this time, the cabinet management unit PMC sets a discharge signal to a low level, after receiving the low level signal, the battery backup system BBS starts to discharge, and simultaneously, the voltage is increased to 12.7V, which is higher than 12.6V output by the power modules PSU, and the power modules PSU are taken over to supply power to the copper bar. After lasting 2S, battery backup system BBS will be 12.3V with output voltage, for preventing that battery backup system BBS lithium cell from overdischarging and leading to the feed, when the electric quantity is less than 5%, stops discharging, and the rack copper bar does not have the power supply at this moment completely.
The invention uses the discharge signal discharge as the discharge trigger signal, can give sufficient discharge reaction time to the battery backup system BBS, the general holding time (hold) of the dual-input power module PSU is more than 16ms, which is that under the condition of full load, the actual working time is much more than 16ms, the actual discharge time from the disconnection of the two inputs of the power module PSU to the starting of the battery backup system BBS is less than 5ms, thus realizing seamless switching. In order to ensure that the cabinet management unit PMC gives a discharge signal most quickly, a signal triggering interruption mode is adopted in the design of the cabinet management unit PMC, namely program interruption is triggered as long as the Vin _ OK signal level changes, and the cabinet management unit PMC enters a mode for processing the signal, so that the corresponding speed is greatly improved compared with the corresponding speed of a traditional mode that the cabinet management unit PMC polls a power supply module PSU.
According to the invention, the initial discharge voltage of the battery backup system BBS is 12.7V, because the power module PSU can output the voltage of 12.6V for a short time after the input of the cabinet is powered off, the output voltage of the battery backup system BBS is higher than the output voltage of the power module PSU, and the situation of voltage drop can not occur when the copper bar is mainly supplied with power by the battery backup system BBS. In addition, the battery backup system BBS outputs 12.7V and maintains 12.3V after 2s, so the design can avoid the misdischarge of the battery backup system BBS under certain conditions, specifically, when only one path of power supply of the cabinet is abnormal, at this time, vin _ OK signals of 6 power supply modules PSU are all at low level, discharge signals are set at the bottom, at this time, the battery backup system BBS should discharge, but the power supply modules PSU are dual-input and still normally work to supply power to the copper bar, if the battery backup system BBS maintains 12.7V all the time, the continuous discharge is caused, which is not desirable, after 2s, the output voltage of the battery backup system BBS is 12.3V, so the copper bar is still supplied with power by the power supply modules PSU, and the battery backup system BBS continues to be used as a backup.
After the power supply of the cabinet is recovered, the output voltage of the power supply module PSU is 12.6V and is higher than 12.3V of the power supply of the battery backup system BBS, the copper bar of the cabinet is supplied with power by the power supply module PSU, and the battery backup system BBS is converted into a charging state.
In summary, the present invention achieves the following functions and advantages in accordance with the foregoing embodiments of the present invention.
1) The centralized power supply mode is adopted, and after the cabinet is powered off by the battery backup system BBS, the battery backup system BBS can still supply power and continuously run for a period of time to wait for the recovery of commercial power or the starting of the generator, so that the data loss is avoided.
2) According to the invention, a mode that the PMC detects the Vin _ OK signal of the power module PSU is adopted, when the number of the power module PSUs is less than 4, the N +2 redundancy cannot be met, at the moment, a discharge signal is given, and the battery backup system BBS starts to discharge, so that the battery backup system BBS starts to take over power supply when the power module PSU is abnormal but still within the holding time (threshold), voltage drop cannot be generated, and the switching process is more stable.
3) The height of a battery backup system BBS is 1U, and a single battery backup system BBS supports 4KW load work for more than 10 minutes. The number of the battery backup systems BBS can be flexibly selected according to the actual power of the cabinet and the expected support time.
4) The cabinet management unit PMC is designed in a mode of signal triggering interruption, namely program interruption is triggered as long as the Vin _ OK signal level changes, and the cabinet management unit PMC enters a mode of processing the signal, so that the corresponding speed is greatly improved compared with the mode that the traditional cabinet management unit PMC polls the power supply module PSU.
According to the invention, uninterrupted power supply of the server can be realized through switching of the battery backup system BBS used in the cabinet and the new battery backup system BBS provided by the invention. By using the technical scheme of the invention, seamless switching can be achieved when the switch power supply of the battery backup system BBS and the power supply module PSU is realized by the cabinet, the hidden danger of voltage drop does not exist, and the stable operation of data center services is ensured. The power supply reliability of the server is greatly enhanced.
