technical field

Background technique

With the continuous development of the Internet, the number and scale of data centers are also continuously expanding. Among them, data centers are used to provide information services for terminals, and they occupy a special position in network applications. Therefore, the data center has high requirements on the security, continuity and reliability of the power supply system.

At present, the data center power supply system uses 220V AC uninterruptible power supply UPS or 240V high-voltage DC as the uninterruptible power supply to supply power to each server in the data center. The power supply voltage output by the above two uninterruptible power supplies is relatively high, and cannot be directly transmitted to each server for use. Therefore, switching power supplies need to be configured in each server to convert the power supply voltage output by the uninterruptible power supply into a voltage that meets the requirements of the server. Since an additional switching power supply needs to be configured for voltage conversion, the existing power supply system is relatively complicated.

Obviously, the described embodiments It is a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection of the present invention. scope.

As shown in Figure 1, an embodiment of the present invention provides an uninterruptible power supply, which may include:

A power module 101, a battery module 102, and a power supply busbar 103; wherein,

The power module 101 is respectively connected to the battery module 102, the power supply busbar 103 and an external power supply, and is used to receive the power supply voltage provided by the power supply, and convert the power supply voltage provided by the power supply to The preset first voltage provides the converted power supply voltage for the power supply bus 103; monitors whether the power supply of the power supply is abnormal, and if so, triggers the battery module 102;

The battery module 102 is respectively connected to the power module 101 and the power supply busbar 103, and is used to provide a power supply voltage for the power supply busbar 103 when receiving the trigger of the power module 101;

The power supply busbar 103 is respectively connected to the battery module 102, the power module 101 and external electrical equipment, and is used to supply power to the electrical equipment using the converted power supply voltage provided by the power module 101 Or use the power supply voltage provided by the battery module 102 to power the electrical device.

According to the embodiment shown in FIG. 1 , the uninterruptible power supply includes a power module, a battery module and a power supply busbar. Firstly, the power module is respectively connected to the battery module, the power supply busbar and the power supply, and the battery module is respectively connected to the power module and the power supply busbar. Then, the power module converts the received power supply voltage provided by the power supply into a preset first voltage, and provides the converted power supply voltage for the power supply busbar. When the power module is used to supply power to the power supply busbar, the power module should also be used to monitor whether the power supply of the power supply is abnormal. When an abnormality of the power supply is monitored, the battery module is triggered to provide a power supply voltage for the power busbar. From the above, it can be seen that the power module in this solution can directly convert the power supply voltage provided by the power supply to the voltage required by the power supply busbar, without additional voltage conversion devices, and when the power supply voltage provided by the power supply is abnormal, the power module can Trigger the battery module to supply power to the power supply busbar. Therefore, the embodiments provided by the present invention can reduce the complexity of the power supply system.

In one embodiment of the present invention, as shown in FIG. 2, the power module 101 includes: a monitoring submodule 201, at least one main power submodule 202, and at least one backup power submodule 203;

Each of the main power sub-modules 202 is respectively connected to the power supply busbar 103 and the power supply, and is used to receive the power supply voltage provided by the power supply, and convert the power supply voltage provided by the power supply to a preset fixed first voltage;

Each of the backup power sub-modules 203 is respectively connected to the power supply busbar 103 and the power supply, and is used to receive the power supply voltage provided by the power supply, and convert the power supply voltage provided by the power supply to a preset fixed first voltage;

The monitoring sub-module 201 is connected to the power supply, the battery module 102, each of the main power sub-modules 202 and each of the backup power sub-modules 203, and is used to monitor each of the main power sub-modules Whether the modules are normal; when it is monitored that each of the main power sub-modules 202 is normal, control each of the main power sub-modules 202 to provide the converted power supply voltage for the power supply busbar; When there is a detected number of the main power sub-modules 202 in the sub-module 202 that is abnormal, control the normal main power sub-module 202 and the detected number of the backup power sub-modules 203 in each of the main power sub-modules 202, for The power supply busbar 103 provides the converted power supply voltage.

In this embodiment, in order to improve the stability of the power supply of the power sub-module, the main power sub-module and the backup power sub-module are respectively set in the power module in a redundant manner. When the main power sub-modules are all working normally, each main power sub-module is controlled to provide the converted power supply voltage for the power supply busbar. When there is a detected number of abnormal main power sub-modules in each main power sub-module, select the detected number of standby power sub-modules in the standby power sub-module to replace the detected number of abnormal main power sub-modules to provide converted power for the power supply busbar Supply voltage to ensure that the power supply busbar can obtain the required voltage.

Usually, the standby power sub-module needs a certain start-up time from receiving the power supply voltage provided by the power supply source to converting the power supply voltage provided by the power supply source to a preset first voltage. If the standby power sub-module is started when the standby power sub-module is controlled to replace the main power sub-module, then during the start-up time, the power supply busbar will not be able to obtain the required voltage, so that the electrical equipment connected to it may not work. Therefore, when the standby power sub-module does not transmit the power supply voltage for the power supply busbar, it is also kept under voltage, so that when the standby power sub-module is controlled to replace the main power sub-module, the standby power sub-module can provide power supply for the power supply busbar in time Voltage.

In this embodiment, the number of main power sub-modules and standby power sub-modules in the power module can be determined according to service requirements. In addition, the specific quantity of the first voltage may also be determined according to service requirements. For example, the power module includes 3 main power sub-modules and 3 backup power sub-modules. Each main power sub-module receives the supply voltage provided by the power supply, and converts the received supply voltage into a first voltage of 12V. Each standby power sub-module receives the power supply voltage provided by the power supply, and converts the received power supply voltage into a first voltage of 12V. When the monitoring sub-module monitors that the three main power sub-modules are normal, control the three main power sub-modules to provide the converted 12V power supply voltage for the power supply busbar. When it is monitored that one of the three main power sub-modules is abnormal, one of the three standby power sub-modules is selected. Then control the normal 2 main power sub-modules and the selected 1 standby power sub-module among the 2 main power sub-modules to provide the converted 12V power supply voltage for the power supply busbar.

According to the above embodiments, the power module includes a monitoring submodule, a main power submodule, and a backup power submodule. The monitoring sub-module can control the main power sub-module and the standby power sub-module to supply power to the power supply busbar according to whether each main power sub-module is abnormal. From the above, it can be seen that the power sub-modules included in the power module are used in a redundant manner. Once there is an abnormal main power sub-module in each main power sub-module, the monitoring sub-module controls the standby power sub-module to replace the abnormal main power sub-module , to supply power to the power supply busbar. Therefore, the power supply is more stable.

In an embodiment of the present invention, the size and power of the power module can be determined according to service requirements. For example, the power range of each power sub-module is optional between 550W and 3000W, and the size is smaller than 315*80*40. Among them, the input rated voltage is 220V, and the output rated voltage is 12V. And concentrate in the 3U space to provide power for the servers in the entire cabinet.

In one embodiment of the present invention, the monitoring sub-module 201 in the schematic structural diagram shown in FIG. 2 is used to monitor the power supply voltage provided by the power supply. When the voltage continues to supply power, and the duration of the continuous power supply reaches a preset time threshold, it is determined that the power supply of the power supply is abnormal, and then the battery module 102 is triggered.

In this embodiment, both the second voltage and the time threshold may be determined according to service requirements. For example, the set second voltage is 220V, and the set time threshold is 5 minutes. The monitoring sub-module is used to monitor the supply voltage provided by the power supply. When the monitored supply voltage is less than the set second voltage 220V, it starts to record the duration of continuously receiving the supply voltage less than 220V. If the duration is not greater than the set When the time threshold is 5 minutes, it means that there are occasional fluctuations in the power supply voltage provided by the power supply, which is normal. If the recorded duration is longer than the set time threshold of 5 minutes, it indicates that the power supply voltage provided by the power supply is abnormal, and it is necessary to stop the power supply of the power supply and trigger the battery module to supply power to the power supply busbar.

According to the above embodiment, the monitoring sub-module determines that the power supply is abnormal and triggers the battery module only when it monitors that the power supply continues to supply power at a voltage not greater than the preset voltage and the duration of the continuous power supply reaches the preset time threshold. Since the relationship between the continuous power supply time and the time threshold needs to be judged, occasional abnormal voltages can be excluded, so the abnormality of the power supply can be accurately determined.

In one embodiment of the present invention, as shown in FIG. 3 , the power module 101 further includes: at least one first hot-swappable sub-module 301 and at least one second hot-swappable sub-module 302; A first hot-swappable sub-module 301 is connected to the at least one main power sub-module 202 in a one-to-one correspondence, and the at least one second hot-swappable sub-module 302 is connected to the at least one standby power sub-module 203 in a one-to-one correspondence ;

Each of the first hot-swappable submodules 301 is used to detect whether the corresponding main power submodule 202 is abnormal, and when detecting that the corresponding main power submodule 202 is abnormal, control the corresponding main power submodule 202 to stop receiving the The supply voltage provided by the power supply mentioned above;

Each of the second hot-swappable submodules 302 is used to detect whether the corresponding standby power submodule 203 is abnormal, and when detecting that the corresponding standby power submodule 203 is abnormal, control the corresponding standby power submodule 203 to stop receiving the The supply voltage provided by the power supply mentioned above.

In this embodiment, when any one of the following at least two conditions exists in the main power sub-module, it is determined that the main power sub-module is abnormal.

Situation 1: After the main power sub-module converts the power supply voltage provided by the power supply to a preset first voltage, the converted power supply voltage does not reach the first voltage;

Situation 2: The temperature of the main power sub-module reaches the preset operating time threshold for a period of time that the main power sub-module continues to operate at a temperature not less than the preset temperature.

According to the above two situations, when the first hot-swappable submodule detects at least one of the above two situations, it determines that the main power submodule is abnormal, and then controls the main power submodule connected to it to stop receiving the power provided by the power supply. supply voltage to stop running.

In this embodiment, similarly, the standby power submodule may also be in any one of the following at least two situations, that is, it is determined that the standby power submodule is abnormal.

Situation 1: After the backup power sub-module converts the power supply voltage provided by the power supply to a preset first voltage, the converted voltage does not reach the first voltage;

Situation 2: The temperature of the standby power sub-module reaches the preset running time threshold for a period of time during which the temperature of the standby power sub-module is continuously operated at a temperature not less than the preset temperature.

According to the above two situations, when the second hot-swappable submodule detects at least one of the above two situations, it determines that the standby power submodule is abnormal, and then controls the standby power submodule connected to it to stop receiving the power provided by the power supply. supply voltage to stop running.

In addition, in this embodiment, each main power sub-module and each backup power sub-module are connected in parallel, and when any one of the modules fails and stops running, the operation of other modules will not be affected.

According to the above embodiments, each main power sub-module and each standby power sub-module has correspondingly connected hot-swappable sub-modules. When any power module is abnormal, it will not affect the operation of other modules. Therefore, the operation independence of each power sub-module is relatively high.

In one embodiment of the present invention, as shown in FIG. 3 , when the power module 101 further includes at least one first hot-swappable submodule 301 and at least one second hot-swappable submodule 302,

The uninterruptible power supply may further include: a first alarm module 303 and a second alarm module 304;

The first alarm module 303 is respectively connected to each of the main power submodules 202, and the second alarm module 304 is respectively connected to each of the backup power submodules 203;

Each of the first hot-swappable sub-modules 301 is further configured to trigger the first alarm module 303 when the corresponding main power sub-module 202 stops receiving the power supply voltage provided by the power supply;

Each of the second hot-swappable sub-modules 302 is further configured to trigger the second alarm module 304 when the corresponding backup power sub-module 203 stops receiving the power supply voltage provided by the power supply;

The first alarm module 303 is configured to alarm when the trigger of the first hot-swap sub-module 301 is received;

The second alarm module 304 is configured to alarm when receiving the trigger of the second hot swap sub-module 302 .

In this embodiment, since the principles and operation methods of the first alarm module and the second alarm module are the same, the first alarm module is used as an example to describe in detail below.

In this embodiment, the first alarm module can have at least the following three types:

Method 1: alarm bell;

Method 2: warning lights;

Method 3: Alarm client.

When the first alarm module adopts mode 1, its alarm mode can be to trigger an alarm bell to inform the business personnel that there is an abnormality in the main power sub-module where it is located, so that the business personnel can deal with the abnormal situation accordingly. When the first alarm module adopts the second method, the alarming method can be to trigger a warning light to inform the business personnel that there is an abnormality in the main power sub-module where it is located, so that the business personnel can deal with the abnormal situation accordingly. When the first alarm module adopts mode three, its alarm method can generate alarm information, and display the alarm information in the alarm client, so that the business personnel can determine that there is an abnormality in the main power sub-module where they are located according to the alarm information, so that the business The personnel will deal with the abnormal situation accordingly.

According to the above embodiments, the uninterruptible power supply may further include a first alarm module and a second alarm module. When the hot-swappable sub-module controls the power sub-module connected to it to stop receiving the power supply voltage provided by the power supply, the alarm module is triggered to give an alarm, so that the business personnel can find out the abnormal power sub-module in time according to the alarm, and correct the abnormal power sub-module. The sub-module makes corresponding processing in time.

In one embodiment of the present invention, as shown in FIG. 4 , the battery module 102 includes a control sub-module 401 and a power supply battery pack 402;

The power supply battery pack 402 is connected to the control sub-module 101 and the power supply busbar 103 respectively, and is used to provide a power supply voltage for the power supply busbar 103 when outputting a power supply voltage.

In this embodiment, the types of the control sub-module and the power supply battery pack can be determined according to business requirements. For example, choose a lithium battery pack with high storage energy density. The control sub-module is BMS (BATTERY MANAGEMENT SYSTEM, battery management system).

In this embodiment, when the power module monitors that the power supply of the power supply is abnormal, the power module triggers the control sub-module. When the control sub-module receives the trigger of the power module, it controls the connected power supply battery pack to output the power supply voltage, so as to provide the power supply voltage for the power supply busbar. From the above, it can be seen that when the power supply of the power supply is abnormal, the power supply battery pack is controlled to output the power supply voltage to supply power to the power supply busbar, so as to achieve the purpose of uninterruptedly supplying power to the power supply busbar.

In this embodiment, the layout principle of the battery modules can be determined according to business requirements, for example, they are arranged in a 2U space.

The control sub-module monitors in real time whether the remaining power of the power supply battery pack is lower than the set power threshold of 2000C. For example, if the remaining power is detected to be less than 2000C, then the charging sub-module will be triggered to use the power supply voltage provided by the external charging power supply for the power supply battery pack. Charge. To ensure that the power supply battery pack has sufficient power to supply power to the power supply busbar.

In this step, the set power modules include monitoring submodules, 3 main power submodules, 3 backup power submodules, 3 first hot-swappable submodules and 3 second hot-swappable submodules. Wherein, the three first hot-swappable sub-modules are connected to the three main power sub-modules in one-to-one correspondence, and the three second hot-swap sub-modules are connected to the three standby power sub-modules in one-to-one correspondence. The battery module includes a control sub-module, a power supply battery pack and a charging sub-module. The positions among the power module, the battery module, and the power supply busbar are shown in FIG. 10 . In FIG. 10 , a power module 1001 , a battery module 1002 and a power supply busbar 1003 are included.

Step 902: Utilize each main power sub-module in the power module to receive the supply voltage provided by the power supply, and convert the supply voltage provided by the power supply into a preset first voltage.

In this step, each of the three main power sub-modules receives the 220V supply voltage provided by the power supply, and converts the received 220V supply voltage into a first voltage of 12V.

Step 903: Utilize each standby power sub-module in the power module to receive the power supply voltage provided by the power supply, and convert the power supply voltage provided by the power supply to a preset first voltage.

Step 904: use the monitoring sub-module in the power module to monitor whether each main power sub-module is normal, if yes, perform step 905, otherwise, perform step 906.

Step 908: Use the monitoring sub-module in the power module to monitor whether the power supply continues to supply power at a preset second voltage, and whether the duration of continuous power supply reaches the preset time threshold, if yes, go to step 909, otherwise , continue with this step.

In this step, when it is monitored that the power supply voltage is lower than the set second voltage 220V, start to record the duration of continuously receiving the power supply voltage less than 220V. If the duration is greater than the set time threshold for 5 minutes, it means that the power supply If the provided power supply voltage is abnormal, the power supply of the power supply needs to be stopped, and the battery module is triggered to supply power to the power busbar, and step 909 is executed.

Step 909: It is determined that the power supply of the power supply is abnormal, then trigger the battery module.

Step 910: When the control sub-module in the battery module receives the trigger of the power module, control the power supply battery pack to output the power supply voltage.

In this step, when the control sub-module in the battery module receives the trigger of the power module, it controls the power supply battery pack to output a 12V power supply voltage.

Step 911: When the power supply battery pack outputs the power supply voltage, it provides the power supply voltage for the power supply busbar.

In this step, the power supply battery pack provides a power supply voltage for the power supply busbar when outputting a 12V power supply voltage.

Step 912: Utilize the control sub-module in the battery module to monitor whether the remaining power of the power supply battery pack is lower than the preset power threshold, if yes, go to step 913, otherwise continue to go to this step.

In this step, the set electric quantity is 2000C. The control sub-module monitors in real time whether the remaining power of the power supply battery pack is lower than the set power threshold 2000C, for example, if it is detected that the remaining power is less than 2000C, step 913 is executed.

Step 913: Use the charging sub-module in the battery module to charge the power supply battery pack with the power supply voltage provided by the charging power supply when receiving the trigger of the control sub-module.

In this step, the power supply battery pack is charged with the power supply voltage provided by the external charging power source. To ensure that the power supply battery pack has sufficient power to supply power to the power supply busbar.
