Description

本発明は、無停電電源装置に接続された複数の設備において、停電等により補助電源が起動したときの停止制御システムに関する。   The present invention relates to a stop control system when an auxiliary power source is activated due to a power failure or the like in a plurality of facilities connected to an uninterruptible power supply.

近年、停電や瞬断（短時間の停電）および電圧低下などの対策としてＵＰＳ（ＵｎｏｎｔｅｒｒｕｐｔｉｂｌＰｏｗｅｒＳｕｐｐｌｙ）やＣＶＣＦ（ＣｏｎｓｔａｎｔＶｏｌｔａｇｅＣｏｎｓｔａｎｔＦｒｅｑｕｅｎｃｙ）に代表される無停電電源装置が設備に接続されている。その殆どの目的は、コンピユーターが内臓されている設備の安全な停止方法にある。   In recent years, uninterruptible power supply devices represented by UPS (Uninterruptable PowerSupply) and CVCF (ConstantVoltageConstantFrequency) are connected to facilities as countermeasures against power outages, instantaneous interruptions (short interruptions), and voltage drops. Most of its purpose is to safely shut down equipment with built-in computers.

コンピユータにとって、電源供給の停止及び電圧の低下は大敵であって、ＯＳ（ＯｐｅｒａｔｉｎｇＳｙｓｔｅｍ）や起動しているアプリケーションは、コンピユーターが停止するまでにファイルやデータを保存してから停止するようになっている。   Stopping power supply and lowering voltage is a major enemy for computers, and OS (Operating System) and running applications are stopped after saving files and data before the computer stops. .

コンピユーターは一般的に処理速度向上のため、ハードディスクへの書き込みのデータを一時的にメモリーに溜めておき後にハードディスクへ書き込む、ディスクキャッシング機能が備わっている。突然、コンピユーターへの電源の供給が停止されると、メモリー内にあるデータがすべて失われることになり、また、各電子部品にも異常な負担をかけることになり寿命を縮める要因ともなっている。   In general, a computer has a disk caching function for temporarily storing data to be written to a hard disk and then writing the data to the hard disk to improve the processing speed. Suddenly, when the power supply to the computer is stopped, all data in the memory is lost, and an abnormal burden is imposed on each electronic component, thereby shortening the life.

さらに、このように異常な停止後の再起動は、通常の起動手順と異なることが多く、起動に多くの手間と時間を要し、業務の早期立ち上げを妨げるという問題もある。   Furthermore, the restart after such an abnormal stop is often different from the normal startup procedure, and it takes a lot of time and labor to start up, and there is also a problem that an early start-up of business is hindered.

無停電電源装置は、基本的には、停電や瞬断によって主電源が切れたり、また設備の規定動作電圧より電圧が下がることがあると、直ちに内臓されているバッテリーから電源を供給するものである。電源を供給できる間に、コンピユーターはＯＳやアプリケーションを正常に終了させ停止する。   An uninterruptible power supply basically supplies power from a built-in battery when the main power is cut off due to a power failure or instantaneous interruption, or when the voltage drops below the specified operating voltage of the facility. is there. While the power can be supplied, the computer normally terminates and stops the OS and applications.

特許文献１では、停電時の無停電電源装置のバッテリー容量を最小限に抑えるために、予め各設備の停止順位を動作電圧の高い順に停止する停止順位を設定し、停電時には停止順位に基づき停止することが提案されている。
特開２０１０−７３０３０号公報 In Patent Document 1, in order to minimize the battery capacity of the uninterruptible power supply at the time of a power failure, a stop order is set in advance so that the stop order of each equipment is stopped in descending order of the operating voltage. It has been proposed to do.
JP 2010-73030 A

しかしながら、稼動している設備の消費電力の大きさを考慮せずに停止順位が決定された場合、結果的に設備全体の運転稼動時間が短くなってしまう場合がある。また、停止している設備が多い場合や設備の更新が頻繁におこなわれる場合、停止順位の見直しが頻繁に発生し、現況の設備状況に即した停止順位の設定が出来ない。さらに、設備の使用状況によって消費電力が変わる場合、事前に適切な停止順位を決定することが難しいという問題がある。   However, when the stop order is determined without considering the power consumption of the facility in operation, the operation operation time of the entire facility may be shortened as a result. In addition, when there are many facilities that are stopped or when facilities are frequently updated, the stop order is frequently reviewed, and it is not possible to set the stop order according to the current equipment state. Furthermore, there is a problem that it is difficult to determine an appropriate stop order in advance when the power consumption changes depending on the use state of the equipment.

そこで本発明は、上記に鑑みてなされたものであって、停電等において主電源から補助電源に切り替わった際に、運転稼動時間が最大となるように各設備の消費電力の大きい順に動作を停止させ、また、主電源復帰時には速やかに動作の停止を解除することができる、無停電電源装置用停止制御システムの提供を目的とする。   Therefore, the present invention has been made in view of the above, and when switching from the main power supply to the auxiliary power supply in the event of a power failure or the like, the operation is stopped in descending order of the power consumption of each facility so that the operation time is maximized. It is another object of the present invention to provide a stop control system for an uninterruptible power supply that can quickly stop the operation when the main power is restored.

The uninterruptible power supply and each facility are connected to a management server via a network. The management server monitors the state of the uninterruptible power supply, a measuring unit that measures the power consumption of each facility, a stop condition setting unit that sets and maintains a condition for stopping the operation of each facility, A control unit that controls the operation of each facility via a network according to the conditions of the stop condition setting unit, and the monitoring unit detects when the uninterruptible power supply is switched to the auxiliary power supply.

A stop control system for an uninterruptible power supply, wherein the stop start time of each facility during operation is determined so as to maximize the operation operation time based on the individual power consumption of each facility.

本発明の第４の態様は、前記第２または第３の態様において、前記制御部は、決定された停止開始時間を前記各設備に通知することを特徴とする無停電電源装置用停止制御システムである。   According to a fourth aspect of the present invention, in the second or third aspect, the control unit notifies the respective facilities of the determined stop start time, and the uninterruptible power supply stop control system is characterized in that It is.

以下、本発明の実施の形態について図面を参照して説明する。
図１は、本発明の実施形態に係わる無停電電源装置用停止制御システムの構成図である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram of a stop control system for an uninterruptible power supply according to an embodiment of the present invention.

無停電電源装置用停止制御システム１は、無停電電源装置２０、設備５１、設備５２、設備５３は、ネットワーク３０を介して管理サーバー１０に接続され、電源の供給は、無停電電源装置２０から電源供給ライン４０を介して各設備５０に供給される構成となっている。   In the uninterruptible power supply stop control system 1, the uninterruptible power supply 20, the equipment 51, the equipment 52, and the equipment 53 are connected to the management server 10 via the network 30, and power is supplied from the uninterruptible power supply 20. It is configured to be supplied to each facility 50 via the power supply line 40.

無停電電源装置２０は、主電源２１と補助電源２２とからなり、一般的に主電源２１から補助電源２２に切り替わる時に、切り替え時間が発生する装置と発生しない装置とがある。本実施形態に係わる設備５１、設備５２，設備５３は、コンピユーターが内臓されている電子機器であり、前記切り替え時間の発生の影響により動作が異常停止する可能性もある。しかしながら、説明の便宜上、本実施の形態では、切り替え時間の発生による影響は無視できるものとする。   The uninterruptible power supply 20 includes a main power supply 21 and an auxiliary power supply 22, and generally, there are a device that generates switching time and a device that does not generate when switching from the main power supply 21 to the auxiliary power supply 22. The equipment 51, the equipment 52, and the equipment 53 according to the present embodiment are electronic devices with built-in computers, and the operation may be abnormally stopped due to the influence of the switching time. However, for convenience of explanation, in this embodiment, it is assumed that the influence due to the occurrence of the switching time can be ignored.

管理サーバー１０は、補助電源２２のバッテリー残容量を監視する監視部１１と、各設備５０のそれぞれの消費電力を計測する計測部１２と、各設備５０の動作を停止させる条件を設定し保持している停止条件設定部１３と、停止条件設定部１３の条件に従って各設備５０の動作をネットワーク３０を介して制御する制御部１４とからなる。   The management server 10 sets and holds a monitoring unit 11 that monitors the remaining battery capacity of the auxiliary power supply 22, a measurement unit 12 that measures the power consumption of each facility 50, and a condition for stopping the operation of each facility 50. And the control unit 14 that controls the operation of each facility 50 via the network 30 according to the conditions of the stop condition setting unit 13.

次に、このように構成された本実施の形態にかかる停電時における管理サーバー１０の各設備５０の停止制御について図２を用いて説明する。図２は、本実施の形態における各設備５０の停止制御の流れを示すフローチャートである。   Next, stop control of each facility 50 of the management server 10 at the time of a power failure according to the present embodiment configured as described above will be described with reference to FIG. FIG. 2 is a flowchart showing a flow of stop control of each facility 50 in the present embodiment.

停電が発生すると、無停電電源装置２０は、主電源２１から補助電源２１に無瞬断で切り替わる。補助電源駆動に切り替わったことは、無停電電源装置２０より管理サーバー１０へ通知される。（Ｓｔｅｐ１）   When a power failure occurs, the uninterruptible power supply 20 switches from the main power source 21 to the auxiliary power source 21 without interruption. The switching to the auxiliary power drive is notified from the uninterruptible power supply 20 to the management server 10. (Step 1)

管理サーバー１０においては、停電の通知を受け、運転中の各設備の消費電力を計測部１２によって測定し、ほぼ同時に監視部１１によって、補助電源２１のバッテリー残容量の常時監視を開始する。（Ｓｔｅｐ２，Ｓｔｅｐ３）   The management server 10 receives a power failure notification, measures the power consumption of each facility in operation by the measuring unit 12, and starts monitoring the remaining battery capacity of the auxiliary power supply 21 almost simultaneously by the monitoring unit 11. (Step2, Step3)

計測部１２より測定された各設備５０のそれぞれの消費電力より、停止条件設定部１３は、各設備の消費電力の大きい順に動作の停止を設定する。（Ｓｔｅｐ４）   Based on the power consumption of each facility 50 measured by the measurement unit 12, the stop condition setting unit 13 sets the operation stop in the descending order of the power consumption of each facility. (Step 4)

次に制御部１４は、停止条件設定部１３により設定された各設備５０の動作の停止条件に基づいて各設備５０の停止開始時間を決定する。   Next, the control unit 14 determines the stop start time of each facility 50 based on the stop condition of the operation of each facility 50 set by the stop condition setting unit 13.

即ち、制御部１４は、計測部１２により測定された各設備５０の消費電力と、監視部１１により監視されている補助電源２２のバッテリー残容量から、運転稼働時間が最大となるように各設備５０の停止開始時間を決定する。（Ｓｔｅｐ５）   That is, the control unit 14 sets each facility so that the operation time is maximized from the power consumption of each facility 50 measured by the measuring unit 12 and the remaining battery capacity of the auxiliary power source 22 monitored by the monitoring unit 11. 50 stop start times are determined. (Step 5)

前記停止開始時間の決定には、各設備の動作停止に際し、ＯＳやアプリケーションが正常に終了することのできる時間を考慮し決定される。   The stop start time is determined in consideration of the time during which the OS or application can be normally terminated when the operation of each facility is stopped.

制御部１４は、前記決定された停止開始時間を各設備に通知し、各設備は通知された停止開始時間に基づき動作の停止を開始する。（Ｓｔｅｐ６）   The control unit 14 notifies each facility of the determined stop start time, and each facility starts operation stop based on the notified stop start time. (Step 6)

このように停電時における各設備５０の消費電力に基づき、動作の停止を動的に決定できる。これにより補助電源２２のバッテリー容量を最大限に活用し、結果的に運転稼働時間を長くすることができる。   Thus, based on the power consumption of each equipment 50 at the time of a power failure, the stop of operation | movement can be determined dynamically. Thereby, the battery capacity of the auxiliary power source 22 can be utilized to the maximum, and as a result, the operating time can be extended.

さらに、各設備５０の動作の停止順が、設備５１、設備５２、設備５３と仮に設定された場合、制御部１４は、停止開始時間通知に基づき設備５１の停止を確認すると、残りの稼動中の設備５２、と設備５３の消費電力を計測部１２により再度取得し、監視部１１によりリアルタイムに監視されている補助電源２２のバッテリー残容量より、再度、運転稼動時間が最大となるように設備５２と設備５３の停止開始時間を再決定し通知する。（Ｓｔｅｐ７）   Furthermore, when the stop order of the operation of each equipment 50 is temporarily set as equipment 51, equipment 52, and equipment 53, the control unit 14 confirms the stop of the equipment 51 based on the stop start time notification, and the remaining operation is in progress. The power consumption of the equipment 52 and the equipment 53 is acquired again by the measuring unit 12, and the equipment so that the operation time is maximized again from the remaining battery capacity of the auxiliary power source 22 monitored in real time by the monitoring unit 11. 52 and the stop start time of the equipment 53 are determined again and notified. (Step 7)

このように、設備が停止する度に、残る稼動中の設備の消費電力を再測定し、常時監視されているバッテリーの残容量から停止開始時間を見直し、停止時間を再設定し通知する。これにより、設備全体の運転稼動時間が一層長くなる。さらに、バッテリー容量が予想以上の減少となっている場合は、動作停止を早めるように制御することも可能である。   In this way, every time the equipment stops, the power consumption of the remaining operating equipment is remeasured, the stop start time is reviewed from the remaining capacity of the battery that is constantly monitored, and the stop time is reset and notified. This further increases the operating time of the entire facility. Furthermore, when the battery capacity is decreasing more than expected, it is possible to control the operation to be stopped earlier.

管理サーバー１０は、全ての設備の停止を確認後、管理サーバー１０も停止する。（Ｓｔｅｐ８）   The management server 10 also stops the management server 10 after confirming the stop of all the facilities. (Step 8)

（変形例） 本発明は以上説明した実施の形態に限定されるものではなく種々の変形が可能である。図１の無停電電源装置用停止制御システムは一例であり、図３のように設備の増設や複数の無停電電源装置を接続するような構成にも対応している。   (Modifications) The present invention is not limited to the embodiment described above, and various modifications are possible. The stop control system for the uninterruptible power supply in FIG. 1 is an example, and it corresponds to a configuration in which facilities are added or a plurality of uninterruptible power supplies are connected as shown in FIG.
