Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は複数の電源装置の出力を同一負荷に接続した多
重化電源装置の障害検出方式に関する。The present invention relates to a failure detection method for a multiplexed power supply device in which outputs of a plurality of power supply devices are connected to the same load.
従来，多重化電源装置の障害検出は，第３図に示すよう

をそれぞれ挿入し，且つ，この整流手段の電源供給側に
電源出力監視手段103〜105をそれぞれ接続して行うよう
にしている。このような構成により，電源供給回路が正
常動作のときは電源出力監視手段が正常出力を検出し，
一方，電源供給回路の出力電圧が上昇あるいは低下する
異常のときは，監視手段が異常を検出して警報を出力す
る。Conventionally, as shown in FIG. 3, the fault detection of the multiplexed power supply device is performed by rectifying means 106-108 on the output lines of the power supply circuits 100-102.
And the power supply output monitoring means 103 to 105 are connected to the power supply side of the rectifying means. With this configuration, when the power supply circuit is operating normally, the power output monitoring means detects the normal output,
On the other hand, when the output voltage of the power supply circuit rises or falls, the monitoring means detects the abnormality and outputs an alarm.
ところが，このような方式では，例えば低電圧で負荷が
大きいとき，整流手段による電力損失の為，効率が悪
く，負荷変動が大きい場合，出力の安定度も悪いという
欠点がある。これに対して，整流手段を削除してしまう
と，どの電源に障害が発生したか判別することが不可能
となっていまう。However, in such a system, when the load is low and the load is large, the efficiency is poor due to the power loss due to the rectifying means, and the output stability is poor when the load fluctuation is large. On the other hand, if the rectifying means is deleted, it becomes impossible to determine which power source has a failure.
以上のような欠点に鑑み，本発明はこれまで電源供給回

It is intended to provide a method.

When detected,
When the predetermined voltage monitoring means instructs the voltage monitoring means of the other power supply device to prohibit the failure processing and stops the power supply circuit by the corresponding power supply start / stop means, and the output is normally restored. When it is determined that the power supply circuit is faulty, an alarm is issued to the outside. On the other hand, when the output is not normally restored, the power supply circuit is restored and at the same time the other power supply device is controlled via the control information transmitting / receiving means. The failure monitoring prohibition is released, and the voltage monitoring means of the power supply device for which the failure processing prohibition is released detects the failure of the power supply circuit by performing the same operation as the power supply circuit. A failure detection method for a multiplexed power supply device is obtained.
次に，本発明の実施例について図面を参照して説明す
る。Next, embodiments of the present invention will be described with reference to the drawings.
第１図は本発明をマイクロプロセッサを利用して，二重
化電源装置に適用した一実施例を示し，第２図はそのフ
ローチャートを示す。FIG. 1 shows an embodiment in which the present invention is applied to a dual power supply unit using a microprocessor, and FIG. 2 shows a flow chart thereof.
第１図において,A−Ｄ変換器220,221は電圧検出手段に
対応し，マイクロプロセッサ230,231は電圧監視手段に
対応し,250,251は電源起動・停止手段,240,241は制御情
報送受手段を示す。In FIG. 1, A-D converters 220 and 221 correspond to voltage detecting means, microprocessors 230 and 231 correspond to voltage monitoring means, 250 and 251 indicate power supply start / stop means, and 240 and 241 indicate control information transmitting and receiving means.
負荷電圧E2はＡ−Ｄ変換器220,221によって二値信号に

サ231は障害処理を開始し自己の電源供給回路211を停止
する。この場合，負荷電圧E2は正常範囲に復旧する為，
マイクロプロセッサ231は電源供給回路211の故障と判断
できるので障害警報手段261に対して警報を出す。The load voltage E2 is converted into a binary signal by the A / D converters 220 and 221, and the microprocessors 230 and 231 constantly determine whether it is within the normal range. Referring also to FIG. 2, it is assumed that an abnormality in one of the power supply circuits and an increase or decrease in the load voltage E2 has been detected by the microprocessor 230, which has a high priority with respect to the monitoring operation. First, in order to prevent contention between both microprocessors, the microprocessor 230 issues an instruction to the microprocessor 231 for prohibiting failure processing to the control information transmission / reception means 240,
Through. Next, the microprocessor 230 instructs the power supply start / stop means 250 to stop its own power supply circuit 210. If the load voltage E2 is restored to the normal range by this, it can be determined that the power supply circuit 210 is in failure, and therefore the failure alarm means 260 issues an alarm to the outside. If the load voltage E2 does not recover normally even if the power supply circuit 210 is stopped, the microprocessor 210 sets the power supply circuit 2 again.
After starting 10, the prohibition of failure processing is released for the microprocessor 231. As a result, the microprocessor 231 starts failure processing and stops its own power supply circuit 211. In this case, the load voltage E2 is restored to the normal range,
Since the microprocessor 231 can determine that the power supply circuit 211 has failed, it issues an alarm to the failure alarm means 261.
以上の説明で明らかな様に，どちらの電源供給回路に障
害が発生してもそれを判別することができる。このよう
な動作は，電源供給回路が３組以上の場合でも同じであ
