Description

  The present invention relates to a communication network system using an uninterruptible power supply in which a computer and peripheral devices are connected via a communication network to an uninterruptible power supply that performs power backup, and more particularly to a network connected to a computer connected to the network. The present invention relates to a communication network system using an uninterruptible power supply device having a Wake ON LAN function that is started from another computer via the network.

The uninterruptible power supply {UPS (Uninterruptible Power Supply)} aims to protect equipment and data by supplying electricity to electrical equipment such as computers using energy stored in storage batteries and capacitors. It is a power supply unit.
In a communication network system using a conventional uninterruptible power supply (UPS), a personal computer (personal computer) that receives a signal from UPS sends a shutdown signal to another personal computer with a pre-set address. To shut down multiple PCs in conjunction with each other.

As a result, the communication network system was safely shut down, and then the UPS was turned off. At the time of power failure recovery, when the UPS power supply is recovered, the personal computer set to be started by BIOS (Basic Input / Output System) is started.
An example of a communication network system using this type of conventional uninterruptible power supply is disclosed in Patent Document 1.
JP-A-11-202986

  By the way, in recent communication network systems using uninterruptible power supply devices, an environment in which an external hard disk drive or a built-in type additional hard disk drive (abbreviated as an additional HDD) is used as a peripheral device of a personal computer. Under such an environment, if the additional HDD has a large capacity when the power is turned on from the UPS at the time of power recovery, it takes time to check the additional HDD, and it takes time to start up.

  For this reason, when the additional HDD is started later than the timing at which the personal computer recognizes the device such as the peripheral device when starting up its own device, a state in which the presence of the additional HDD cannot be recognized occurs. In order to eliminate such a state, a UPS is added when an HDD is added, and the startup timing of the personal computer is delayed from that of the additional HDD by connecting the additional HDD to the added UPS, that is, a UPS different from the personal computer. There was a need. In this case, since a UPS must be added every time a peripheral device such as a large-capacity HDD, which requires a longer startup time than a personal computer, is added, there is a problem that the expansion cost becomes high.

  The present invention has been made in view of such a problem, and when adding a peripheral device of a computer that takes longer to start than the computer in an environment where the computer can be started via a network, the cost of the expansion is increased. It is an object of the present invention to provide a communication network system using an uninterruptible power supply that can reduce power consumption.

To achieve the above object, a communication network system using an uninterruptible power supply according to claim 1 of the present invention provides a communication network for an uninterruptible power supply that backs up power of a computer and peripheral devices used in the computer. the computer is connected through, in a communication network system using an uninterruptible power supply having a function of start through the communications network other computers connected to the communication network, the uninterruptible power supply, self setting means for unique address of the connected the computer is set, the power recovery detection means for detecting a power recovery power, the time until power before distichum side apparatus is activated from the supply set And time-up when the set time elapses from the power recovery detection time of the power recovery detection means. And the step, after the time-up of the clock means, a Ping signal to the computer connected to the self-checks whether running, the first to be transmitted to the setting means to set address of the computer If there is a response to the transmission of the Ping signal by the first transmission unit, the computer determines that the computer is activated, and if there is no response, the first determination unit determines that the computer is not activated, and the first determination unit. When it is determined that the computer has not been started, an MP signal for starting the computer is transmitted to the unstarted computer, and the Ping signal is transmitted again to the computer to which the MP signal is transmitted. The second transmission means for notifying the first transmission means, and when the activation is determined by the first determination means, the activation completion confirmation to the activation computer A second transmitting unit for determining whether or not the corresponding computer has started up if there is a response to the transmission of the start completion confirmation signal by the third transmitting unit, and determining that the startup has not been completed if there is no response. The determination means is provided.

  According to this configuration, the computer can be automatically started after the additional peripheral device is started up by the control of the same uninterruptible power supply at the time of power recovery. Therefore, the same uninterruptible power supply can be connected to the same uninterruptible power supply without connecting the additional peripheral device and the computer to separate uninterruptible power supply units and delaying the computer startup timing from the additional peripheral device. The expansion peripheral device can be connected to the computer. Accordingly, even when a peripheral device such as a large-capacity HDD that takes longer to start than a personal computer is added, the cost of the extension can be reduced.

A communication network system using an uninterruptible power supply according to claim 2 of the present invention is the activation detection means for detecting activation of its own computer in a computer that activates another computer via the communication network. And a setting means for setting a unique address of the other computer; and a time from when power is supplied to a peripheral device to be added to the other computer until the start-up is set. Time setting means for timing up when the set time has elapsed from the time of detection, and a Ping signal for confirming whether or not the other computer is activated after time is up for the time setting means to the setting means A first transmission means for transmitting to the computer at the set address, and a Ping signal of the first transmission means; If there is a response to the communication, the computer determines that the corresponding computer is activated, and if there is no response, the first determination unit determines that the computer is not activated. The second transmission for transmitting the MP signal for starting the computer to the first computer, and notifying the first transmission means so that the Ping signal is transmitted again to the computer to which the MP signal has been transmitted. Means, a third transmitting means for transmitting a start completion confirmation signal to the computer of the start when the first determination means determines that the start is completed, and a start completion confirmation signal of the third transmission means. If there is a response to the transmission, the computer determines that the activation is completed, and if there is no response, the second determination means determines that the activation is not completed .

  According to this configuration, an additional peripheral device used by a computer to be controlled can be automatically activated after completion of activation by control via a communication network from an arbitrary computer at the time of power recovery. Therefore, when the additional peripheral device is started later than the timing at which the computer recognizes the additional peripheral device when starting up the own device, it is possible to eliminate a situation in which the presence of the additional peripheral device cannot be recognized. As a result, even in a communication network environment in which the number of computers serving as terminals is large, all computers can be automatically started after power is restored.

  As described above, according to the present invention, when adding a peripheral device of a computer that takes longer to start than the computer in an environment in which the computer can be started via a network, the expansion cost can be reduced. There is an effect.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, parts corresponding to each other in all the drawings in this specification are denoted by the same reference numerals, and description of the overlapping parts will be omitted as appropriate.
FIG. 1 is a block diagram showing a configuration of a communication network system using an uninterruptible power supply according to an embodiment of the present invention.
The communication network system shown in FIG. 1 includes a UPS 10, first to sixth servers 11, 12, 13, 14, 15, 16, an additional HDD 17, and a HUB (local area network) concentrator. Hub) 18.
As for the connection form of these components 10 to 18, the UPS 10 and the third to sixth servers 13 to 16 are connected to the commercial power supply 21 through the power line, and the first and second servers 11 and 12 are connected to the UPS 10. Are connected to the additional HDD 17.

  The UPS 10 includes a plurality of built-in network connectors 22 that can also be used as a HUB. The built-in network connector 22 is connected to the first and second servers 11 and 12 and the HUB 18 via a LAN line. Are connected to the third to sixth servers 13 to 16. That is, the first and second servers 11 and 12 can communicate with the third to sixth servers 13 to 16 via the built-in network connector 22 and the HUB 18.

The UPS 10 includes a first terminal activation control unit 23 that automatically activates the first and second servers 11 and 12 when power is restored. The second server 12 includes a second terminal activation control unit 24 that automatically activates the third to sixth servers 13 to 16 after the server 12 is activated by the first terminal activation control unit 23.
As shown in FIG. 2, the first terminal activation control unit 23 includes a transmission destination address setting unit 31, an address read control unit 32, a power recovery detection unit 33, a timer 34, a Ping transmission unit 35, a Ping A response reception determination unit 36, an MP transmission unit 37, an activation completion confirmation transmission unit 38, and an activation completion response reception determination unit 39 are provided.

In the transmission destination address setting unit 31, a MAC (Media Access Control) address and an IP (Internet Protocol) address of a signal transmission destination server are set.
The address read control unit 32 reads the MAC address or IP address set in the transmission destination address setting unit 31 in a predetermined order.
The power recovery detection unit 33 detects power recovery of the commercial power source 21.

The timer 34 is set so that the time from when power is supplied to the additional HDD 17 until it is activated is set as the count time. The timer 34 performs the counting operation from the time when the power recovery detection unit 33 detects power recovery. When this count operation exceeds the set count time, the time is up.
The Ping transmission unit 35 receives the Ping signal for checking whether or not the target terminal device (server) is activated after the timer 34 has expired. To send to.

The Ping response reception determination unit 36 determines whether a Ping response signal that is a response from the partner server to the Ping signal transmitted by the Ping transmission unit 35 is received or not received. Here, it is possible to determine that the partner server is activated if there is a response from the server to which the Ping signal is transmitted, and is not activated if there is no response.
When the Ping response reception determination unit 36 determines that the MP transmission unit 37 has not received, the MP transmission unit 37 reads the MAC read by the address read control unit 32 in pairs with the IP address that transmitted the Ping signal for this determination. An MP (Magic Packet) signal is transmitted to the server at the address. The MP signal is a signal for starting the server.

  In addition, the MP transmission unit 37 notifies the address read control unit 32 that the MP signal has been transmitted, and the address read control unit 32 that has received the notification transmits the next order set in the transmission destination address setting unit 31. Read the IP address and MAC address of Then, after all the addresses have been read, the IP address and the MAC address are read again in the same order, and the Ping transmission unit 35 transmits the Ping signal again using the IP address read again.

If there is no response to the retransmitted Ping signal, the MP transmission unit 37 determines that the server is in an unstarted state due to some failure.
The activation completion confirmation transmitting unit 38 transmits an activation completion confirmation signal to the server of the IP address that transmitted the Ping signal for this determination when the Ping response reception determination unit 36 determines reception.

The activation completion response reception determination unit 39 is activated when an activation completion response signal that is a response from the partner server to the activation completion confirmation signal transmitted by the activation completion confirmation transmission unit 38 is received. In this case, it is determined that the system has not been activated, and in this case, the activation completion confirmation transmitting unit 38 is instructed to transmit an activation completion confirmation signal to the server again.
Further, the activation completion response reception determination unit 39 determines that the corresponding server is in an incomplete activation state due to some failure if there is no response to the activation completion confirmation signal transmitted again.

  Next, the second terminal activation control unit 24 basically has the same configuration as the first terminal activation control unit 23, except that the second terminal activation control unit 24 is replaced with the power recovery detection unit 33, as shown in FIG. And the timer 34 performs a counting operation from the time when the activation is detected by the activation detecting unit 41, and the time is up when the counting operation exceeds the set count time. Yes.

However, if the additional HDD 17 is on the UPS 10 side as shown in FIG. 1 and is not the third to sixth servers 13 to 16 on the second server 12, the count time is zero. Is set. In other words, a ping signal is transmitted from the ping transmitter 35 immediately after the activation is detected by the activation detector 41.
The operation of the activation process of each of the servers 11 to 16 at the time of power recovery in the communication network system having such a configuration will be described with reference to the flowchart shown in FIG. FIG. 4 is a flowchart for explaining the operation when the first terminal activation control unit 23 of the UPS 10 activates the first and second servers 11 and 12 at the time of power recovery.

As a prerequisite, the MAC address and IP address of the first and second servers 11 and 12 are set in the transmission destination address setting unit 31 of the first terminal activation control unit 23, and the second terminal activation control unit 24. It is assumed that the MAC address and the IP address of the third to sixth servers 13 to 16 are set in the destination address setting unit 31.
The timer 34 of the first terminal activation control unit 23 is set as a count time from when power is supplied to the additional HDD 17 until it is activated, and the timer 34 of the second terminal activation control unit 24 is Assume that count time = 0 is set.

  First, in step S1, it is assumed that the power recovery detection unit 33 of the first terminal activation control unit 23 detects the power recovery of the commercial power source 21. By this detection, the timer 34 performs a counting operation in step S2. If it is determined in step S3 that the counting operation has exceeded the set count time, the first IP address and MAC in the predetermined order set in the destination address setting unit 31 in step S4. The address is read.

In step S5, the Ping signal is transmitted from the Ping transmission unit 35 to the first server 11 of the read IP address.
In step S <b> 6, the Ping response reception determination unit 36 determines whether a Ping response signal is received from the first server 11 for the transmitted Ping signal. At this timing, since each server 11 to 16 is in an unstarted state because power is restored, no Ping response signal is returned.

Accordingly, the determination of the Ping response reception determination unit 36 is not received. Accordingly, in step S7, the MP transmission unit 37 first uses the first server 11 based on the MAC address paired with the IP address of the destination of the Ping signal. The MP signal is transmitted to.
In step S8, when the MP transmission unit 37 notifies the address read control unit 32 that the MP signal has been transmitted to the first server 11 in step S7, the operations in steps S4 to S8 are performed again. The That is, in step S4, the address read control unit 32 that has received the notification in step S8 reads the IP address and MAC address of the second server 12 in the next order set in the transmission destination address setting unit 31. .

In step S5, the Ping signal is transmitted from the Ping transmission unit 35 to the second server 12 of the read IP address.
In step S6, the Ping response reception determination unit 36 determines whether a Ping response signal is received from the second server 12 for the transmitted Ping signal. Even at this timing, since the second server 12 is not activated, the Ping response signal is not returned.

Therefore, the determination of the Ping response reception determination unit 36 is not received. Accordingly, in step S7, the MP transmission unit 37 first uses the second server 12 based on the MAC address paired with the transmission destination IP address of the Ping signal. The MP signal is transmitted to.
In step S8, when the MP transmission unit 37 notifies the address read control unit 32 that the MP signal has been transmitted to the second server 12 in step S7, the operations in steps S4 to S8 are further executed. . That is, at the timing of this step S4, since the IP address and MAC address of the second server 12 in the last order set in the transmission destination address setting unit 31 as described above are read out, the first address again. The IP address and MAC address of one server 11 are read out.

  In step S5, a Ping signal is transmitted to the first server 11. In step S6, it is determined whether or not a Ping response signal is received from the first server 11 for the transmission. At this timing, if the first server 11 is in a normal state, the Ping response signal is returned because it is in an activated state. Therefore, the determination of the Ping response reception determination unit 36 is reception.

When the process for the first server 11 is completed, the same process is performed for the second server 12 in steps S4 to S6. However, if the Ping response signal is not returned at the timing of transmitting the second Ping signal, the MP transmitting unit 37 determines that the corresponding server is in an unstarted state due to some failure.
Next, in step S9, the activation completion confirmation transmission unit 38 transmits an activation completion confirmation signal to the first server 11 of the IP address that has normally received the Ping response signal. In step S <b> 10, the activation completion response reception determination unit 39 determines whether an activation completion response signal has been received from the first server 11 in response to the activation completion confirmation signal.

In the case of reception, in step S11, the activation completion response reception determination unit 39 determines that the first server 11 is activated. If not received, it is determined in step S12 that it has not been activated. In the case where it has not been activated, the activation completion confirmation signal is transmitted again to the corresponding server 11 in step S9. In step S10, the activation completion response signal is transmitted from the first server 11 in response to the activation completion confirmation signal transmitted again. It is determined whether or not is received.
If it has not been received, the activation completion response reception determination unit 39 determines in step S12 that the server 11 is in an activation incomplete state due to some failure. When the processing for the first server 11 is completed, the same processing is performed for the second server 12 in steps S9 to S12.

Next, with reference to the flowchart shown in FIG. 5, the operation | movement at the time of starting the 3rd-6th servers 13-16 by the 2nd terminal starting control part 24 is demonstrated. However, in this description of operation, only the components of the second terminal activation control unit 24 shown in FIG. 3 are cited.
If it is determined in step S11 that the second server 12 is activated, the activation detection unit 41 of the second terminal activation control unit 24 of the second server 12 in step S21 of FIG. Activation is detected.
Since the count time of the timer 34 is set to 0 in the second terminal activation control unit 24, immediately after activation is detected in step S21, the predetermined order set in the transmission destination address setting unit 31 in step S22 The first IP address and MAC address are read out.

  In step S23, the Ping signal is transmitted from the Ping transmission unit 35 to the third server 13 of the read IP address. In step S24, the Ping response reception determination unit 36 determines whether or not a Ping response signal for the transmitted Ping signal has been received from the third server 13. At this timing, since the power is restored, the third to sixth servers 13 to 16 are not activated, and therefore no Ping response signal is returned.

Accordingly, the determination of the Ping response reception determination unit 36 is not received. Accordingly, in step S25, the MP transmission unit 37 first uses the third server 13 based on the paired MAC address and the IP address of the transmission destination of the Ping signal. The MP signal is transmitted to.
In step S26, when the MP transmission unit 37 notifies the address read control unit 32 that the MP signal has been transmitted to the third server 13 in step S25, the operations in steps S22 to S26 are performed again. The That is, in step S22, the address read control unit 32 that has received the notification in step S26 reads the IP address and MAC address of the fourth server 14 in the next order set in the transmission destination address setting unit 31. .

In step S23, a Ping signal is transmitted from the Ping transmission unit 35 to the fourth server 14 of the read IP address.
In step S24, the Ping response reception determination unit 36 determines whether or not a Ping response signal has been received from the fourth server 14 for the transmitted Ping signal. Even at this timing, since the fourth server 14 is not activated, the Ping response signal is not returned.

Accordingly, the determination of the Ping response reception determination unit 36 is not received. Accordingly, in step S25, the MP transmission unit 37 first uses the fourth server 14 based on the MAC address paired with the IP address of the destination of the Ping signal. The MP signal is transmitted to.
In this way, similar processing is executed in steps S22 to S26 in the remaining fifth and sixth servers 15 and 16 as well.

  In step S26, when the MP transmission unit 37 notifies the address read control unit 32 that the MP signal has been transmitted to the sixth server 16 in step S25, the transmission destination is transmitted at the timing of the next step S22. Since the IP address and MAC address of the sixth server 16 in the last order set in the address setting unit 31 are read, the IP address and MAC address of the third server 13 at the head are read again.

  In step S23, a Ping signal is transmitted to the third server 13. In step S24, it is determined whether a Ping response signal is received from the third server 13 for the transmission. At this timing, if the third server 13 is in a normal state, it is in an activated state, so a Ping response signal is returned. Therefore, the determination of the Ping response reception determination unit 36 is reception.

When the process for the third server 13 is completed, the same process is performed for the other fourth to sixth servers 14 to 16 in steps S22 to S24. However, if the Ping response signal is not returned at the timing of transmitting the second Ping signal, the MP transmitting unit 37 determines that the corresponding server is in an unstarted state due to some failure.
Next, in step S27, the activation completion confirmation transmission unit 38 transmits an activation completion confirmation signal to the third server 13 of the IP address that has normally received the Ping response signal. In step S <b> 28, the activation completion response reception determination unit 39 determines whether an activation completion response signal has been received from the third server 13 in response to the activation completion confirmation signal.

  In the case of reception, in step S29, the activation completion response reception determination unit 29 determines that the third server 13 is activated. If not received, it is determined in step S30 that it has not been activated. In the case where it has not been activated, the activation completion confirmation signal is transmitted again to the corresponding server 11 in step S27, and the activation completion response signal is transmitted from the third server 13 to the activation completion confirmation signal transmitted again in step S28. It is determined whether or not is received.

  If not received here, in step S30, the activation completion response reception determination unit 39 determines that the corresponding server 13 is in an activation incomplete state due to some failure. When the processing for the third server 13 is completed, the same processing is performed for the other fourth to sixth servers 14 to 16 in steps S27 to S30. As a result, all the servers 11 to 16 are in a startup completion state.

  As described above, according to the communication network system using the uninterruptible power supply according to the present embodiment, the first and second servers are automatically operated after the additional HDD 17 is started up under the same UPS 10 control at the time of power recovery. 11 and 12 can be activated. For this reason, it is possible to connect the additional HDD and the computer to the same UPS without connecting the additional HDD and the server to individual UPSs and delaying the server startup timing from the additional HD as in the prior art. be able to. Accordingly, even when a peripheral device such as a large-capacity HDD that takes longer to start than a personal computer is added, the cost of the extension can be reduced.

  Further, when power is restored, the servers 13 to 16 can be automatically started up after completion of the startup of the additional peripheral devices used by the servers 13 to 16 to be controlled by control from any server 12 via the communication network. Therefore, when the additional peripheral device is started later than the timing at which the server recognizes the additional peripheral device when the server is started, it is possible to eliminate a situation where the presence of the additional peripheral device cannot be recognized. As a result, even in a communication network environment in which the number of servers serving as terminals is large, it is possible to automatically start all the servers after power is restored.
