In an actual application scene, a power module fault often occurs in a server cabinet of a data center, so that a single branch circuit is powered off, equipment in the server cabinet is stopped, the power load of a power module of another branch circuit of the server cabinet is increased, and then the safety operation of the equipment in the server cabinet is seriously influenced due to faults and the like.
For example, some devices in a server cabinet, such as some types of switches and common server devices, only support one power supply, and if power interruption occurs, such devices can be directly stopped and cannot work normally.
For another example, after the upper power supply device of one branch in the server cabinet is suddenly interrupted, the power module of the other branch in the server cabinet immediately increases the load by one time, and the power module is damaged by impact caused by the sudden load increase, so that a fault is caused.
In order to solve the problems, the disclosure provides a power supply switching system and a power supply switching method for a server cabinet, which can timely perform power supply switching when single-side power supply of the server cabinet is abnormal, and ensure that electric equipment such as a switch or a server in the server cabinet can work normally.
FIG. 1 is a schematic diagram according to a first embodiment of the present disclosure; as shown in fig. 1, the present embodiment provides a power supply switching system 10 of a server cabinet, including: a controller 11 and a power conversion module 12; the power conversion module 12 includes a switching unit 121 and a battery 122.
The controller 11 is electrically connected with cabinet incoming lines of two branches for supplying power to the current server cabinet respectively and is used for detecting whether the cabinet incoming line power supply of the current server cabinet is abnormal or not; if the cabinet incoming line of one branch is abnormal in power supply and the cabinet incoming line of the other branch is normal in power supply, the switching unit 121 in the power conversion module 12 is controlled to be conducted, and the electric quantity of the cabinet incoming line of the normal power supply branch is introduced to the branch with abnormal power supply;
The controller 11 is further configured to control the battery 122 to supply power to the branch circuit with abnormal power supply before the switching unit 121 is turned on.
For example, in fig. 1, cabinet incoming lines of two branches of a current server cabinet are respectively taken as an a-path cabinet incoming line and a B-path cabinet incoming line of the current server cabinet as an example.
In this embodiment, the controller 11 can detect whether the power supply of the two cabinet incoming line branches of the current server cabinet is abnormal. And determines that the power supply of the cabinet inlet wire of one branch is abnormal, and the power supply of the cabinet inlet wire of the other branch is normal, and controls the switching unit 121 in the power conversion module 12 to be conducted, so that the electric quantity of the cabinet inlet wire of the normal power supply branch can be introduced to the branch circuit with abnormal power supply, and the double-circuit power supply of the server cabinet can be continuously realized.
Because of a certain time consumption in the switching of the switching unit 121, in order to supply power to the power supply abnormality branch in time, in this embodiment, before the switching unit 121 is turned on, the controller 11 may control the battery 122 in the power conversion module 12 to supply power to the power supply abnormality branch, so as to ensure that the service cabinet is in the scene of two-way power supply at any time, thereby further effectively improving the safety performance of the server cabinet.
In practical application, the power conversion module 12 may also adopt other structures, as long as the electric quantity of the cabinet incoming line of the normal power supply branch can be introduced to the power supply abnormal branch, which is not limited herein.
The power supply switching system 10 of the server cabinet of the embodiment can timely switch the cabinet incoming line of the other side to continue to supply power for the cabinet incoming line branch of the abnormal side when the cabinet incoming line of the server cabinet is abnormal in power supply, and can continuously ensure the double-circuit power supply of the server cabinet, so that the safety performance of the server cabinet can be effectively improved.
For example, when only one power supply is supported for some devices in the server cabinet, such as some types of switches and common server devices, if one branch of the server cabinet is interrupted, the devices may be directly stopped and cannot work normally. By adopting the technical scheme of the embodiment, the power supply can be switched in time, the electric quantity of the cabinet incoming line of the normal power supply branch is introduced to the branch circuit with abnormal power supply, the double-circuit power supply of the server cabinet is continuously realized, the double-circuit power supply of the server cabinet is ensured, and further, the safe operation of the equipment can be effectively ensured without shutdown.
For another example, after the upper power supply device of one branch in the server cabinet is suddenly interrupted, the power module of the other branch in the server cabinet immediately increases the load by one time, and the power module is damaged by impact caused by the sudden load increase, so that a fault is caused. By adopting the technical scheme of the embodiment, the impact damage caused by the increase of the load of the power module of the other branch can be effectively avoided, so that the failure rate of the server cabinet can be effectively reduced, and the operation safety performance of the server cabinet is improved.
FIG. 2 is a schematic diagram according to a second embodiment of the present disclosure; as shown in fig. 2, the power supply switching system 10 of the server cabinet of the present embodiment further describes the technical solution of the present disclosure in more detail on the basis of the technical solution of the embodiment shown in fig. 1.
As shown in fig. 2, the power supply switching system 10 of the present embodiment further includes an alarm module 13; the alarm module 13 is electrically connected with the controller 11;
the controller 11 is configured to control the alarm module 13 to send an alarm prompt message of two-way power interruption when detecting that the two-way power supply of the current cabinet is abnormal.
Further optionally, in one embodiment of the present disclosure, the controller 11 is configured to detect whether a current of the PDU of the present server rack is within a first abnormal value range; if yes, determining that the incoming line of the cabinet is abnormal in power supply; otherwise, determining that the power supply of the cabinet incoming line is normal. The first outlier range may be set from 0 to a preset threshold according to the situation of the actual scene, where the preset threshold may be a smaller value close to 0, such as 1 or other smaller values, which is not limited herein. In theory, if the controller 11 detects that the current of the cabinet inlet on one branch of the current server cabinet is 0, it determines that the cabinet inlet is abnormal in power supply. However, in an actual scenario, the actual current that may be detected is not equal to 0, for example, may be 1, or some fraction between 0 and 1, etc., due to an error or the like, at which time power supply abnormality has actually occurred. Based on this, in this embodiment, by setting the first abnormal value range, accuracy and detection efficiency of cabinet incoming line power supply abnormality detection can be improved.
The two cabinet incoming lines of the server cabinet are detected by adopting the mode, so that the detection accuracy and the detection efficiency can be effectively ensured.
Further alternatively, as shown in fig. 2, in one embodiment of the present disclosure, the controller 11 is also electrically connected to two main wires that power a plurality of server racks, respectively; the plurality of server cabinets comprise a current server cabinet, and two main incoming lines are respectively positioned at the upstream of cabinet incoming lines of two branches of the current server cabinet; for example, in fig. 2, two main lines are taken as an example of an a main line and a B main line.
The controller 11 is configured to:
detecting whether the power supply of a main inlet wire at the inlet wire branch side of the cabinet with abnormal power supply is abnormal or not when detecting that the power supply of the inlet wire of the cabinet of one branch of the current server cabinet is abnormal and the power supply of the inlet wire of the cabinet of the other branch is normal;
if so, further detecting whether the resistance of the PDU at the inlet side of the cabinet with abnormal power supply is in a second abnormal value range;
if the PDU or the backend equipment has short circuit, the control alarm module 13 sends out an alarm prompt message.
Similarly, the setting principle of the second abnormal value range of the present embodiment is the same as the setting principle of the first abnormal value range. For example, the second abnormal value range may be set to a range from 0 to a preset resistance value according to the actual situation, and the preset resistance value may be a smaller value close to 0, such as 1, 2, 5 or other smaller values, which is not limited herein. By adopting the mode, the accuracy and the detection efficiency of abnormality detection can be effectively improved, and the accuracy of alarming can be further improved.
In this embodiment, the alarm module 13 may exist alone as a functional module. Or the functions of the alarm module 13 may be incorporated in the controller 11. In this embodiment, the alarm prompt message sent by the alarm module 13 may be transmitted to the column cabinet and send out an audible and visual alarm. The remote terminal of control is connected with in the cabinet of listed as the first cabinet under the general condition, so, not only can release the warning prompt message of alarm module 13 in the control of cabinet of listed as first cabinet, can also conduct this warning prompt message to the remote terminal of control through the monitored control system of cabinet of listed as first for the fortune dimension personnel can in time obtain the warning prompt message, in time handle the trouble, avoid bigger trouble, ensure the safe operation of server rack.
In addition, in this embodiment, the controller is connected in parallel with the server device, and is in the same electrical environment as the server device, so that when it monitors the abnormal problem of the circuit, the controller can timely control the alarm module 13 to transmit the alarm prompt information to the column cabinet and can send out audible and visual alarm.
Further optionally, in an embodiment of the present disclosure, the controller 11 is specifically configured to, when detecting that the cabinet incoming line power supply of one branch of the current server cabinet is abnormal, and the cabinet incoming line power supply of the other branch is normal, control the switching unit 121 in the power conversion module 12 to be turned on when the main incoming line power supply of the cabinet incoming line branch side with abnormal power supply is abnormal and the main incoming line power supply of the cabinet incoming line branch side with normal power supply is determined to be normal.
Further alternatively, in one embodiment of the present disclosure, the switching units 121 in the power conversion module 12 are electrically connected to PDUs of two branches of the current server rack, respectively. For example, fig. 3 is a schematic diagram of a server enclosure provided by the present disclosure. As shown in fig. 3, in the server cabinet 100, the power conversion module 12 may be connected to the PDU of the a path and the PDU of the B path in the server cabinet, so as to implement that the power conversion module 12 is electrically connected to the cabinet incoming lines of the two branches of the current server cabinet power supply. Referring to the description of the above embodiment, it can be known that the switching unit 121 in the power conversion module 12 is specifically connected to the PDU of the a path and the PDU of the B path in the server cabinet, respectively. Of course, the battery 122 in the power conversion module 12 is also connected to the PDU of the a path and the PDU of the B path in the server cabinet, so as to supply power to the PDU of the abnormal power supply branch by the battery 122 before the switching unit 121 is turned on.
The controller 11 is configured to control the power conversion module 12 to communicate the PDU of the normal power supply branch and the PDU of the abnormal power supply branch, so that the PDU of the normal power supply branch supplies power to the PDU of the abnormal power supply branch.
Further alternatively, as shown in fig. 2, in one embodiment of the present disclosure, the batteries 122 are also electrically connected to PDUs of both branches of the current server rack, respectively;
The controller 11 supplies power to the PDU of the power supply abnormal branch by the PDU of the power supply normal branch when the switching unit 121 in the power supply conversion module 12 is controlled to be conducted;
the controller 11 is further configured to control the battery 122 to supply power to the PDU of the power supply abnormality branch of the current server rack before the switching unit 121 is turned on.
In this embodiment, when the electric quantity of the battery 122 is the PDU power supply of the power supply abnormality branch, a certain preset time period, for example, 20ms, can be maintained, so that enough time is striven for the controller 11 to control the operation of the switching unit 121, and it can be effectively ensured that the server cabinet can still operate safely when the single-side power supply of the server cabinet is abnormal. In actual operation, the power storage amount of the battery 122 may be configured according to the maximum duration consumed for controlling the switching unit 121 to be turned on in an actual application scenario. Through multiple experiments, the battery 122 can supply power for 20ms, so that the conduction of the switching unit 121 can be ensured.
Further optionally, in an embodiment of the present disclosure, the power conversion module 12 further comprises an inverter or chopper; one end of the inverter or chopper is electrically connected with the battery 122, and the other end is electrically connected with the PDU of the power supply abnormal branch of the current server cabinet.
For example, fig. 4 is a schematic diagram of a power conversion module provided by the present disclosure. As shown in fig. 4, if the power supply requirement of the current server cabinet is ac, the controller 11 controls the battery 122 to start, the inverter 123 converts the dc power output by the battery 122 into ac power, and outputs the ac power to the PDU of the abnormal power supply branch of the current server cabinet, so as to effectively satisfy the power supply requirement of the current server cabinet. For example, fig. 4 is a schematic diagram of a power conversion module provided by the present disclosure. The inverter 123 is used to convert Direct Current (DC) into alternating Current (Alternating Current; AC), so the inverter 123 may also be a DC/AC unit.
As shown in fig. 4, N/-represents the neutral of the a-way cabinet inlet and L/+ represents the hot of the a-way cabinet inlet. The switching unit 121, and the inverter 123 are electrically connected to N/-and L/+ of the a-way cabinet incoming line and the B-way cabinet incoming line, respectively. The controller 11 may control the battery 122 to supply power to the branch having the abnormal power supply through the inverter 123 when the power supply of a certain branch is abnormal. And at the same time, the switching unit 121 is controlled to be conducted, so that the electric quantity of the normal power supply branch circuit is introduced to the branch circuit with abnormal power supply. Since the switching unit 121 needs a certain time for being turned on, it is ensured that the battery 122 can supply power to the power supply abnormality branch in time before the switching unit 121 is turned on.
For example, fig. 5 is a schematic diagram of another power conversion module provided by the present disclosure. As shown in fig. 5, if the power supply requirement of the current server rack is dc, the controller 11 controls the battery to start, and the chopper converter 124 processes the dc output by the battery 122 and outputs the processed dc to the PDU of the abnormal power supply branch of the current server rack, so as to effectively meet the power supply requirement of the current server rack. The chopper converter 124 can convert direct current with fixed voltage value into direct current with variable voltage value so as to meet the power supply requirement of the server. The rebroadcast converter 124 may also be a DC/DC unit. The working principle is described with reference to fig. 4, and is not described here again.
For example, fig. 6 is a schematic diagram of yet another power conversion module provided by the present disclosure. As shown in fig. 6, the power conversion module 12 includes an inverter 123 as an example. As shown in fig. 6, the switching unit 121 includes a triac 1211 and a relay circuit 1212; the bidirectional thyristor 1211 and the relay circuit 1212 are electrically connected to the PDUs of the two branches of the current server rack, respectively;
the controller 11 is configured to control the bidirectional thyristor 1211 to be turned on when it is determined that the switching unit 121 in the power conversion module 12 needs to be controlled to be turned on, so as to control the PDU of the power supply normal branch of the current server cabinet to supply power to the PDU of the power supply abnormal branch;
The controller 11 is further configured to control the relay circuit 1212 to close, and further control the electrical connection between the PDU of the normal power supply branch and the PDU of the abnormal power supply branch of the current server rack, and switch from the bidirectional thyristor 1211 connection to the relay circuit 1212 connection.
Further alternatively, as shown in fig. 6, in one embodiment of the present disclosure, the relay circuit 1212 includes: a parallel circuit of a relay coil 1212a and a switch 1212 b; two ends of the parallel circuit are respectively and electrically connected with PDU of two branches of the current server cabinet;
when the controller 11 controls the relay circuit 1212 to be closed, the relay coil 1212a is controlled to be conducted, and then the electrical connection between the PDU of the normal power supply branch and the PDU of the abnormal power supply branch of the current server cabinet is controlled, and the connection is switched from the bidirectional thyristor 1211 to the connection of the relay coil 1212 a;
further, the controller 11 controls the switch 1212b to be closed, so as to control the electrical connection between the PDU of the normal power supply branch and the PDU of the abnormal power supply branch of the current server cabinet, and the connection of the relay coil 1212a is switched to the connection of the switch 1212 b.
The power supply switching system 10 of the server cabinet of the present embodiment is in a standby/shutdown state: all the switches are opened, and the controller 11 detects the power supply state of the two-path PDU equipment of the current server cabinet in real time.
If one of the PDUs is powered down due to the interruption of the upper power supply, for example, the voltage of the PDU in the a path is reduced by taking the power-off in the a path as an example, the controller 11 controls the power supply of the PDU in the a path to be instantaneously supplied by the battery 122 in the above manner of the embodiment. Meanwhile, the controller 11 drives the triac 1211 to conduct rapidly within 20ms, and simultaneously drives the relay coil 1212a to close the relay; the reason for this configuration is that the on time of the triac 1211 is extremely short, and the rapid switching of the power supply can be realized, and the loss of the relay is lower than that of the triac 1211, so that the relay is put into operation, and the line loss and the equipment heat are reduced. Finally, the switch key 1212b is closed, and the switch key 1212b is directly closed, so that the impact on the circuit is larger, and the circuit can be closed after the relay coil 1212a is closed, and the stability of the circuit is improved; and the loss of the switch key 1212b is lower, so that the switch key 1212b can introduce the electric quantity of the cabinet inlet wire of the normal power supply branch to the branch with abnormal power supply after the switching unit 121 in the power conversion module 12 is conducted stably. By adopting the above results of the embodiments of the present disclosure, the power conversion module 12 can be enabled to stably and efficiently introduce the electric quantity of the cabinet inlet wire of the normal power supply branch onto the abnormal power supply branch.
In the embodiment of the disclosure, the configured battery 122 only needs to meet the requirement of 20ms power supply operation of the server cabinet, after the power supply is switched, the two-way power supply of the server cabinet is normal, and at this time, the power supply module of any branch of the server cabinet can also automatically charge the battery 122.
In the technical scheme of the embodiment, when the server cabinet is subjected to single-circuit power failure, the power conversion module can be switched in time to continuously supply power for the PDU with power failure, so that the power supply continuity of the server in the cabinet is maintained; the safety performance of the server cabinet can be effectively improved.
In the technical scheme of the embodiment, the controller can distinguish the failure cause based on the abnormality, further perform action/refusal action or send out alarm information, prevent operation and maintenance personnel from misoperation to cause larger failure, and effectively guarantee the safety performance of the server cabinet.
In the technical scheme of the embodiment, the controller can also be connected with a remote monitoring system such as a train head cabinet and a remote terminal for monitoring, has communication capability, can timely send out alarm prompt information when alarming, and improves the running safety performance of the server cabinet.
According to the technical scheme, the fault recording capability is further provided, for example, the controller 11 can record the current sudden increase/sudden decrease, voltage fluctuation and other conditions of the server cabinet, so that the state of the server cabinet is conveniently analyzed, faults of the server cabinet, PDU or equipment in the server cabinet are judged in advance, and the safety performance of the server cabinet and the equipment in the server cabinet can be effectively improved.
