DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system requiring a large-scale and non-stop operation, and more particularly to a plurality of uninterruptible devices incorporating a battery, that is, a plurality of UPS (unint).
The present invention relates to a UPS device comprising an erroneous power system.

[0002]

2. Description of the Related Art Conventionally, when a large-scale server system (for example, a cluster configuration, etc.) is required and non-stop operation is required, a UPS is generally introduced due to a power failure or a power supply failure. It is a target. The UPS has a built-in battery. When a commercial power supply fails, the UPS operates the battery to convert DC to AC and supply power to a load, that is, a server.

[0003]

The above-mentioned conventional UP
S operates the built-in battery to supply power,
There is a drawback in that it is not possible to cope with a power failure beyond the usable time of the battery.

[0004] It is an object of the present invention to provide a UPS device which does not stop power supply due to a limited use time of a built-in battery at the time of power failure.

[0005]

SUMMARY OF THE INVENTION The present invention provides a UPS device capable of mutual monitoring and supply of power, comprising a plurality of uninterruptible devices including a battery, that is, a UPS device comprising a UPS.
The UPS includes a mutual monitoring communication means connected to the other UPS, a mutual monitoring means for constantly monitoring the power status of the partner UPS via the mutual monitoring communication means, and a power supply cable connected to the other UPS. If the mutual monitoring means detects that the UPS battery has been activated due to a power supply abnormality of the partner UPS, and if the own battery is not operating, a power supply for supplying power to the partner UPS with a power supply cable is provided. The start of the/
The power supply start / stop unit having the stop unit includes a unit that stops the power supply to the partner UPS when the mutual monitoring unit detects that the power abnormality of the partner UPS has been recovered.

[0006] Some UPSs include two UPSs.

[0007] Some UPSs include three UPSs.

[0008] A plurality of UPSs include four UPSs.

[0009] The case where n is an integer of 5 or more and a plurality of UPSs are n is included.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a UPS device capable of mutual power supply monitoring and supply according to a first embodiment of the present invention, and FIG. 2 is a flowchart showing the operation of the UPS device of FIG.

In the UPS device shown in FIG. 1, a UPS 1 and a UPS 2 are mutually connected by a power supply cable 4 and a mutual monitoring LAN 5. The UPS 1 includes a mutual monitoring unit 11, a power supply start / stop unit 12, and a battery 13, and receives power from a commercial power supply 14 and supplies it to the server 6. Similarly, the UPS 2 includes a mutual monitoring unit 21, a power supply start / stop unit 22, and a battery 23, and receives power from a commercial power supply 24 and supplies it to the server 7. Both the UPS 1 and the UPS 2 have a normal UPS function of operating the batteries 13 and 23 and supplying AC-converted power in the event of a commercial power failure. The mutual monitoring units 11 and 21 constantly monitor the power status of the other UPS through the mutual monitoring LAN 5. The power supply start / stop units 12 and 22 are connected to the mutual monitoring unit 11 respectively.
And 21 detect that the batteries 13 and 23 of the other UPS have operated due to a power supply abnormality of the other UPS, and if the batteries 13 and 23 of the own UPS are not operating, the power supply cable 4 connects the other UPS to the other UPS. Supply power. The power supply start / stop units 12 and 22 stop the power supply to the partner UPS when the mutual monitoring units 11 and 21 detect that the power supply abnormality of the partner UPS has been recovered.

Next, the operation will be described.

As shown in FIG. 2, in the operation of the first embodiment, when an abnormality occurs in the commercial power supply 14, 24 system of one of the UPS 1 or 2 during normal operation (step 1) (step 2). The power supply is switched to the battery 13 or 23 by the UPS function due to the power supply abnormality. The UPS that is operating normally detects this by the mutual monitoring unit 11 or 21 (step 3). Next, the normal operation side UPS
Confirm that its own built-in battery is not operating (step 4). At this time, if the system is in operation, both sides operate as a normal UPS as it is (step 5). When the UPS battery on the normal operation side is not operating, the start / stop unit 12 or 22 of the power supply is used to detect the abnormality
Power supply to the PS is started (step 6). This allows operation without being limited by the battery capacity. Next, when the power supply system in which the abnormality has occurred is restored (step 7), the mutual monitoring unit 11 or 21 also knows that fact from the power supply side (step 8). The power supply start / stop unit 12 or 22 stops the power supply (step 9) and returns to the normal operation state (step 1).

In the UPS device capable of mutual power supply monitoring and supply according to the present embodiment, when the internal battery of one UPS operates due to a power supply abnormality, power is supplied from another UPS, so that the available time of the battery is limited. Power supply is not stopped.

FIG. 3 is a block diagram of a UPS device capable of mutually monitoring and supplying power according to a second embodiment of the present invention.

The UPS device shown in FIG. 3 is composed of UPS1, UPS2 and UPS3.
Are mutually connected by power supply cables 41, 42, 43 and mutual monitoring LANs 51, 52, 53. UPS1,2,3 are mutual monitoring unit 11,
21 and 31, power supply start / stop units 12, 22, and 32, and batteries 13, 23, and 33;
Power is received from the servers 4, 34 and supplied to the servers 6, 7, 8. The mutual monitoring units 11, 21, 31 are connected to the mutual monitoring LAN 5.
Via 1, 52 and 53, the status of the power supply of the partner UPS is constantly monitored. Power supply start / stop unit 12, 2
2 and 32, when the mutual monitoring units 11, 21, and 31 detect that the battery of the partner UPS has operated due to a power supply abnormality of the partner UPS, a power supply cable if the battery of the own UPS is not operating. The power is supplied to the partner UPS by 41, 42, and 43, and when the mutual monitoring units 11, 21, and 31 detect that the power supply abnormality of the partner UPS has been recovered, the power supply to the partner UPS is stopped. .

In the UPS device of the present embodiment capable of mutual power supply monitoring and supply, similarly to the UPS device of FIG. 1, when a built-in battery of one UPS operates due to a power failure, power is supplied from another UPS. Therefore, the power supply is not stopped due to the limitation of the usable time of the battery.

In the present embodiment, the UPS device is constituted by three UPSs, but the number of UPSs may be four, or n may be n, where n is an integer of 5 or more.

In the above embodiment, power is supplied to the server, but power may be supplied to other loads.

[0021]

As described above, according to the present invention, by providing the UPS with the mutual monitoring communication means, the mutual monitoring means, the power supply cable, and the power supply start / stop means, the other party's UPS can be provided. If the UPS battery is detected to be running due to a power failure in the UPS, and if its own battery is not running, the power supply start / stop means supplies power to the other UPS through the power supply cable. There is an effect of realizing a UPS device in which power supply is not stopped by being restricted by a usable time of a built-in battery at the time of abnormality.
