Background

At present, power distribution bars aiming at a server rack usually have a power distribution state information monitoring function and a remote information interaction function, and a plurality of power distribution bars are connected to an IP port of a network switch and transmit monitored power distribution state information to a remote monitoring terminal through the network switch. When a certain power distribution bar cannot monitor and transmit power distribution state information due to power failure, the monitoring terminal can give an alarm for the power distribution bar which does not receive the power distribution state information.

However, when one of the power distribution bars in the series is powered off, the power distribution bar in the power distribution bar cannot continue to monitor and transmit the power distribution state information, and a transmission terminal of the power distribution state information of the power distribution bars in the series is caused, so that the monitoring terminal may give an alarm to the power distribution bars which do not receive the state information, and the alarm information is inaccurate.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

Example one

Fig. 1 shows an application scenario diagram of power distribution bar monitoring according to a first embodiment of the present application. As can be seen from the figure, in an application scenario of the power distribution bar monitoring of the embodiment of the present application, the power distribution bar monitoring includes a plurality of power distribution bars 101, a network switch 102, a monitoring terminal 103, a server 104 that is provided with power by a connected power distribution bar, and a plurality of power supply lines 105 that provide power to the connected power distribution bar. The distribution bars are connected in series, and one of the distribution bars is connected with the monitoring terminal 103 through the network switch 102.

Currently, a common Power Distribution strip includes a Power Distribution Unit (Power Distribution socket) of an intelligent rack. The intelligent rack power distribution bar can monitor power supply voltage, current, power supply power, voltage frequency and other electric energy parameters in real time.

Fig. 2 is a diagram illustrating a structure example of a power distribution bar according to a first embodiment of the present application. As can be seen from the figure, the power distribution bars 101 are respectively provided with a network communication control board 1011, and the network communication control board is mainly used for monitoring power distribution state information such as power distribution power information, power distribution voltage information, and power distribution current information of the power distribution bars 101, and transmitting the information to the monitoring terminal 103 through the network switch 102.

More specifically, a network communication interface 10111 is provided on the network communication control board of each distribution bar. The network communication interface 10111 is designed to support both the information exchange with the external device and the function of obtaining standby power from the external device through the active ethernet. On the other hand, the power distribution state information can be transmitted between the plurality of power distribution bars 101 and between the power distribution bars 101 and the network switch 102 through the network communication interface 10111 of the network communication control board 1011. On the other hand, the network communication interface 10111 may receive power provided by the network switch 102 and transmit the power to the network communication interface 10111 of the other power distribution bar.

In practical application, the standby Power can be obtained from the external device through the active Ethernet by using a POE (Power Over Ethernet) Power supply technology. The POE power supply technology is a technology that, without any change in the existing ethernet wiring infrastructure, can provide dc power supply for some terminals based on IP (Internet Protocol, internetworking Protocol) while transmitting data signals.

Further, the distribution bar 101 is provided with a single-phase three-wire circuit 1012 to input electric power from an external power supply line. The power distribution bar 101 is also provided with a socket 1013 to provide an adapted power supply interface to a connected powered device such as a server or the like. The distribution bar 101 is provided with a transformer 10112 for the network communication control board 1011 to adjust the input ac voltage.

In practical applications, the manner in which the above-mentioned distribution bars are connected in series and connected to the network switch by one distribution bar is called cascade connection. The advantage of a tandem connection is that only one IP address of the network switch is occupied. However, when a power supply line 105 fails or a power distribution bar 101 fails, and the power distribution bar cannot normally supply power to the network communication control board 101, the network communication control board 1011 cannot operate, and the power distribution status information of the plurality of communication control boards connected in series with the network communication control board 1011 cannot be transmitted to the monitoring terminal 103. The monitoring terminal 103 may alarm for a plurality of power distribution bars 101 that do not transmit power distribution state information, thereby causing a problem of inaccurate alarm information.

Fig. 3 is a schematic diagram illustrating a scene of an error in alarm information in a cascade connection mode. As can be seen from the figure, power distribution bars 101A, 101B, 101C and 101D are included in the application scenario. The distribution bars are connected in series through the network communication control board, wherein the network communication control board 101D1 of the distribution bar 101D is connected with the network switch.

Under the condition that the power distribution bars normally supply power, the network communication control board 101A1 of the power distribution bar 101A can acquire local power distribution state information and send the power distribution state information to the network communication control board 101B1 of the next series-connected power distribution bar 101B, and the network communication control board 101B1 can send the power distribution state information acquired from the power distribution bar 101B to the next series-connected power distribution bar 101C together with the power distribution state information of the power distribution bar 101A until the network monitoring control board of the power distribution bar 101D transmits the power distribution state information of all the power distribution bars to the network switch 102 together.

When the power supply line of the power distribution bar 101C has a power supply failure, the power distribution bar 101C is locally powered off, and the power cannot be supplied to the network communication control board 101C 1. The network communication control board 101C1 cannot normally operate by using electric energy, and therefore cannot transmit the power distribution state information of the power distribution bar 101A, the power distribution bar 101B, and the power distribution bar 101C, so that the monitoring terminal 103 can only receive the power distribution state information of the power distribution bar 101D, and give an alarm for the power distribution bar 101A, the power distribution bar 101B, and the power distribution bar 101C. However, only the power distribution bar 101C actually has a power supply failure, resulting in an erroneous alarm information.

In this embodiment, when the power distribution bars 101 normally supply power to the network communication control board 1011, the network communication control board 1011 may use the power provided by the power distribution bars 101 to send the power distribution state information of a plurality of power distribution bars to the network switch 102, and the network switch 102 transmits the collected power distribution state information about the plurality of power distribution bars 101 to the monitoring terminal 103, so that the monitoring terminal 103 displays the power distribution state information on an operation page of a power supply device.

When a certain power supply line 105 fails or a certain power distribution bar 101 fails, the network communication control board 1011 or the network switch 102 may determine the power distribution bar that cannot normally supply power due to the failure as a target power distribution bar, and determine that the power distribution bar is currently in a power-off state in which the power supply bar cannot supply power. Specifically, when the network communication control board 1011 detects that the voltage input by the transformer 10112 is lower than a preset voltage threshold, it may be determined that the target distribution bar is currently in a power-off state; or, after the network switch 102 detects that the communication state with the network communication control board 1011 is abnormal, it determines that the target distribution bar 101 is currently in the power-off state, and notifies the target network communication control board 1011 to open the network communication interface 10111. When network communication control board 1011 determines that the target distribution bar cannot provide power currently, or receives a notification from network switch 102, network communication interface 10111 may be turned on to obtain the standby power provided by network switch 102 through network communication interface 10111.

After the network communication control board 1011 obtains the standby power, the standby power may be used to send the power distribution state information of other power distribution bars connected in series with the target power distribution bar and the power supply alarm information for the target power distribution bar to the network switch 102, or send the power distribution state information to the next power distribution bar 101 connected in series for final transmission to the network switch 102. Thus, the network switch 102 can collect the power distribution state information of the power distribution bar in which the power failure has not occurred and the power supply alarm information of the target power distribution bar in which the power failure has occurred, and transmit them to the monitoring terminal 103. The monitoring terminal 103 may display the power distribution status information to the user, or may save the power distribution status information in a power distribution status log, or send power outage prompt information to the target powered device powered by the target power distribution bar to instruct the target powered device to enable standby power.

In practical applications, the network communication control board 1011 may obtain the standby power and be in a hot standby power supply mode, so as to send the power distribution status information and the power supply alarm information to the network switch 102 by using the standby power after the local power failure of the power distribution bar. The hot standby power supply mode is a power supply mode in which standby power is continuously supplied under the condition that the power distribution bar is normally supplied with power so as to switch the power supply mode immediately when the power is cut off and the standby power continues to operate.

For example, a local power outage at the distribution bar 101C may not provide power to the network communication control board 101C 1. When the network communication control board 101C1 detects that the voltage input by the transformer is lower than the preset voltage threshold, it determines that the distribution bar 101C is currently in the power-off state; alternatively, after the network switch 102 detects the abnormal state of the communication with the network communication control board 101C1, it determines that the target distribution bar 101C is currently in the power-off state, and notifies the network communication control board 101C 1. After determining that the power distribution bar 101C cannot supply power or receives the notification from the network switch 102, the network communication interface may be opened, the standby power is obtained through the network communication interface 101C11, and the power distribution state information of the power distribution bars 101A and 101B and the power supply alarm information of the power distribution bar 101C are sent to the network communication control board 101D1 by using the standby power, and the received power distribution state information and power supply alarm information of other power distribution bars and the power distribution state information of the power distribution bar 101D are sent to the network switch 102 by using the power distribution state information and power supply alarm information of the power distribution bars. The monitoring terminal 103 can acquire the power distribution state information of the power distribution bars 101A, 101B, and 101D and the power supply alarm information of the power distribution bar 101C from the network switch 102, so that an alarm can be given only to the power distribution bar 101C without giving an alarm to the power distribution bar 101A and the power distribution bar 101B.

In practical application scenarios, the power distribution bar 101 and the power supply line 105 are usually connected by an electric wire, and the electric wire transmits the alternating current provided by the power supply line 105 to the power distribution bar 101. The distribution bar 101 is also typically connected to the server 104 by wires, through which ac power is transmitted to the server 104. The network communication control board 1011 usually has a transformer installed on the power supply loop of the power distribution bar 101 for supplying power to the server 104, and the network communication interface 10111 of the network communication control board 1011, and the network communication interface 10111 and the network switch 102 may be connected through network cables. The network lines between the network communication interfaces 10111 and the network switch 102 may be media for network information transmission and power transmission in network hardware. Through the connection of the network cable, the network communication interface 10111, and the network communication interface 10111 and the network switch 102, information interaction can be performed, and the direct current provided by the network switch 102 can be transmitted to the network communication interface 10111. Of course, the skilled person can make adjustments according to actual situations, for example, an external backup power supply device is provided to be connected to the network communication interface 10111 through a wire, and when the power distribution bar is locally powered off, ac power can be transmitted from the backup power supply device to the network communication interface 10111 through the wire.

According to the embodiment of the application, under the condition that the distribution bars are locally powered off, the network communication control board can acquire standby electric energy from the network switch to continue to operate, the power distribution state information of the series-connected distribution bars and the power supply alarm information of the failed distribution bars are transmitted to the monitoring terminal through the network switch, the monitoring terminal can accurately position the failed distribution bars according to the power distribution state information and the power supply alarm information, the alarm of the distribution bars without faults is avoided, and the accuracy of the alarm information is improved.

Example two

Fig. 4 is a flowchart illustrating steps of a power distribution bar monitoring method according to a second embodiment of the present application, where a network communication control board is disposed on a power distribution bar, the network communication control boards are electrically connected to each other, a monitoring platform for monitoring an electric energy state of the power distribution bar is electrically connected to one of the network communication control boards, and a network communication interface is disposed on the network communication control board, and the network communication interface supports obtaining standby electric energy from the monitoring platform through an active ethernet network, where the method includes the following steps:

step 201, the network communication control board sends the power distribution state information of a plurality of power distribution bars to the monitoring platform by using the electric energy of the power distribution bars.

The monitoring platform comprises a network switch and a monitoring terminal, wherein the network switch is used for monitoring the electric energy states of a plurality of power distribution bars and providing standby electric energy for the power distribution bars, and the monitoring terminal is used for providing the electric energy states of the power distribution bars for users.

It should be noted that, a network communication control board may be provided for each power distribution bar, and the network communication control board may monitor and collect power distribution state information of the power distribution bar. The power distribution status information may include power parameters including voltage, current, power supply, voltage frequency, etc. currently provided by the power distribution bar.

In specific implementation, under the condition that the power distribution bars normally supply power, the network communication control panel can acquire electric energy from the power distribution bars so as to monitor and collect the electric energy, and send the collected power distribution state information to the next serially-connected network communication control panel so as to finally transmit the power distribution state information of the power distribution bars to the monitoring platform.

In practical application, the network communication control panel can acquire standby electric energy and be in a hot standby power supply mode so as to adopt the standby electric energy to send power distribution state information and power supply alarm information to the monitoring platform after the power distribution bar is locally powered off. The hot standby power supply mode is a power supply mode in which standby power is continuously supplied under the condition that the power distribution bar is normally supplied with power so as to switch the power supply mode immediately when the power is cut off and the standby power continues to operate.

Step 202, when it is determined that the target power distribution bar cannot provide electric energy currently, the network communication interface is opened to obtain standby electric energy provided by the monitoring platform through the network communication interface.

When a certain power supply line or a certain distribution bar has a fault, the network communication control board can determine the distribution bar which cannot normally supply power due to the influence of the fault as a target distribution bar. The specific implementation manner of determining that the power distribution bar cannot supply power currently may be various, for example, when the network communication control board detects that the voltage input by the transformer is lower than a preset voltage threshold, it may be determined that the target power distribution bar is powered off currently. And when the target distribution bar cannot provide the electric energy currently, the network communication interface powered by the hot backup supplies the required electric energy.

And 203, sending the power distribution state information of the power distribution bars connected with the target power distribution bar in series and the power supply alarm information aiming at the target power distribution bar to the monitoring platform by using standby electric energy for displaying by the monitoring platform.

After the network communication control board obtains the standby electric energy, the standby electric energy can be adopted to send the power distribution state information of other power distribution bars connected with the target power distribution bar in series and the power supply alarm information aiming at the target power distribution bar to the monitoring platform. Therefore, the monitoring platform can collect the power distribution state information of the power distribution bars without power failure and the power supply alarm information of the target power distribution bars with power failure.

EXAMPLE III

Fig. 5 is a flowchart illustrating steps of a power distribution bar monitoring method according to a third embodiment of the present application, where a network communication control board is disposed on a power distribution bar, the network communication control boards are electrically connected to each other, a monitoring platform for monitoring an electric energy state of the power distribution bar is electrically connected to one of the network communication control boards, and a network communication interface is disposed on the network communication control board, and the network communication interface supports obtaining standby electric energy from the monitoring platform through an active ethernet network, where the method includes the following steps:

step 301, the network communication control board sends the power distribution state information of a plurality of power distribution bars to the monitoring platform by using the electric energy of the power distribution bars.

Step 302, when detecting that the voltage input by the transformer of the network communication control board is lower than a preset voltage threshold, determining that the target distribution bar cannot provide the electric energy to the network communication control board currently.

In a specific implementation, the network communication control board may detect a voltage of a transformer provided for the network communication control board, and when the voltage is lower than a preset voltage threshold, it indicates that the current output voltage of the target distribution bar is abnormal and may be in a power-off state, so that it may be determined that the target distribution bar cannot provide electric energy to the network communication control board at present.

In practical application, in order to facilitate a user to read the power distribution state information of the power distribution bar in real time, an instrument for displaying the power distribution state information can be arranged on the network communication control panel, and the instrument can provide the step-down electric energy by the transformer.

In practical application, a switching value can be added to the transformer as a monitoring point, and the switching value outputs a signal indicating the current voltage condition to the network communication control board.

Step 303, when it is determined that the target power distribution bar cannot provide power currently, the network communication interface is opened to obtain the standby power provided by the monitoring platform through the network communication interface.

And 304, sending the power distribution state information of the power distribution bars connected with the target power distribution bar in series and the power supply alarm information aiming at the target power distribution bar to the monitoring platform by using standby electric energy for displaying by the monitoring platform.

Optionally, the step 303 may comprise the following sub-steps:

substep S303-1 (not shown in the figure), when receiving the notification of the monitoring platform, opening the network communication interface; the monitoring platform detects the abnormal state of communication with a target network communication control board, and informs the target network communication control board to start a network communication interface when determining that the target distribution bar cannot supply power at present.

In a specific implementation, after the monitoring platform detects that the state of communication with the network communication control board is abnormal, it is determined that the target distribution bar is currently in a power-off state, and the target network communication control board is notified to start a network communication interface. After receiving the notification of the monitoring platform, the network communication interface can be opened to obtain the standby electric energy provided by the monitoring platform through the network communication interface. The monitoring platform can have various implementation modes for detecting the power failure of the distribution bar, for example, the monitoring platform can periodically send a communication state confirmation request to each network communication control panel, and when a communication state confirmation message fed back by a target network communication control panel is not received within preset time, the monitoring platform determines that the target distribution bar cannot supply power currently and correspondingly sends a notification to the target network communication control panel; or, the monitoring platform may monitor a time interval of each network communication control board transmitting the power distribution state information, and when the time interval of the target network communication control board transmitting the power distribution state information exceeds a preset time threshold, determine that the target power distribution bar cannot supply power currently and correspondingly transmit a notification to the target network communication control board. In practical application, the power supply of the network communication interface can be switched from the power supply of the power distribution bar to the power supply of the network communication interface of the hot backup power supply in a hot backup switching mode.

It should be noted that, the determination of the power-off state of the power distribution bar may be performed by the network communication control board, by the monitoring platform, or by both, and those skilled in the art may determine the power-off state of the power distribution bar in various manners according to actual needs.

step 401, obtaining, from the network switch, power distribution state information of the multiple power distribution bars, which is sent by the network communication control board by using the electric energy of the power distribution bars.

In the concrete realization, under the condition that the distribution bar normally supplies power, the network communication control panel on the distribution bar can acquire electric energy from the distribution bar, and adopt this electric energy to monitor and gather to the distribution state information of distribution bar, and send the distribution state information who gathers to the network communication control panel of next series connection, in order finally to transmit the distribution state information of a plurality of distribution bars to the network switch. Therefore, the information interaction terminal can acquire the power distribution state information of the power distribution bars from the network switch.

In specific implementation, when a certain power supply line or a certain distribution bar has a fault, the network communication control board can determine the distribution bar which cannot normally supply power due to the influence of the fault as a target distribution bar. When the target power distribution bar cannot provide electric energy at present, the network communication interface can be started to obtain the standby electric energy provided by the monitoring platform through the network communication interface. After the network communication control board obtains the standby electric energy, the standby electric energy can be adopted to send the power distribution state information of other power distribution bars connected with the target power distribution bar in series and the power supply alarm information aiming at the target power distribution bar to the network switch. Therefore, the information interaction terminal can acquire the power distribution state information of the power distribution bar normally supplying power and the power supply alarm information of the target power distribution bar in power failure from the network switch.

Step 403, sending a power outage prompt message to a target powered device powered by the target power distribution bar to instruct the target powered device to enable standby power.

It should be noted that the power distribution bar may supply power to one or more powered devices, such as a server. When the information interaction terminal receives power supply alarm information, one or more target powered devices connected with the information interaction terminal and supplying power can be determined according to the power-off target power distribution bars, and power-off prompt information is sent to the target powered devices. The powered device receiving the power outage prompt message may enable the standby power according to the indication of the power outage prompt message. In practical application, the standby electric energy can be obtained from other power distribution bars connected with the target powered device, and the standby electric energy can also be obtained from a network communication control panel of the power-off target power distribution bar. Of course, those skilled in the art can determine the specific emergency measures taken by the target powered device when receiving the power outage prompt message according to actual situations.
