【発明の属する技術分野】
本発明は、制御装置を制御盤によって制御しているとき、活線状態のまま制御盤を新規のものに更新するという制御盤の更新方法に関する。
【0002】
【従来の技術】
従来の多くの制御装置が電力線や信号線、通信線など多数の配線を介して制御盤によって制御されている。そのようなシステムが長年使われていると、新しい制御盤が作られ、操作性や効率、機能等の点からみて優れている場合は、新しい制御盤と入れ替えられるというようなことがあった。そのように、制御盤を新規のものと入れ替えられるときは、概ね次のような手順で更新されていた。
ステップ1:設備を停止する。
ステップ2:既設制御盤と制御装置を接続している配線を全て外す。
ステップ3:既設制御盤を退避場所に退避させる。
ステップ4:配線を延長し、既設制御盤に接続する。
ステップ5:既設制御盤を一時的に稼動させて動作を確認する。
ステップ6:当初既設制御盤があった場所に新設制御盤を設置する。
ステップ7:新設制御盤に模擬回路を接続し、一時的に稼動させて動作試験をする。
ステップ8:ステップ7で動作が正常であれば、模擬回路を除去して正規の配線をする。
ステップ9:新設制御盤を稼動させ、動作確認をして更新を完了する。
【0003】
【発明が解決しようとする課題】
ところが、この従来の方法では次のような問題があった。
(1)模擬回路を使用するため、実際の設備に即した検証試験をするのに多大な時間を要する。
(2)切替えに際して、設備の停止時間が長くかかり、稼動時間が減少して実質的なコスト高となっている。
【0004】
【課題を解決するための手段】
そこで本発明の制御盤更新方法は、既設制御盤と、その既設制御盤によって制御される制御装置と、前記既設制御盤と前記制御装置を接続する多数の配線とで構成する稼働中のシステムにおいて、次の手順によって前記既設制御盤を新設制御盤に入れ替えることを特徴としたのである。
ステップ1:各配線毎に、閉じたa接点と開いたb接点の2接点を持つ中継盤を準備して、閉じたa接点の両端から2本の中継ケーブルを既設制御盤に導く。
ステップ2:前記2本の中継ケーブルの先端を、間をおいて前記配線に活線状態で直スリーブ接続する。
ステップ3:直スリーブ接続した2ヶ所の間の前記配線を活線状態で切断する。
ステップ4:前記既設制御盤を活線状態で退避場所に移設する。
ステップ5:端子台を備えた新設制御盤を前記既設制御盤があった場所に設置する。
ステップ6:前記端子台の1端子を前記制御装置に接続し、もう1端子を、前記a接点の一端と接続されて前記制御装置に接続されたb接点のもう一端に接続する。
ステップ7:前記中継盤のb接点を閉じて、前記制御装置と新設制御盤を接続する。
ステップ8:前記端子台の接続を切替え、前記制御装置と前記新設制御盤とを直接接続する。
ステップ9:前記中継ケーブルを除去して前記既設制御盤と前記中継盤を除去する。
以上の手順を踏むことによって、設備の停止時間と更新のための作業を最小に保ち、実際の設備に即した確実な試験をすることができるのである。
【0005】
【発明の実施形態】
以下、本発明の実施の形態を図に基づいて説明する。図1は本発明の方法を適用した設備の更新作業の経過を配線状況の経過とともに示す図であり、図2はその手順を示すフローチャートである。図において、1は取替えようとする既設制御盤、2は新しく取り入れる新設制御盤、3は2つの接点を持つ中継盤、4は既設制御盤1の入出力部であるI/O、5は端子台、6は新設制御盤2のI/O、7は2本の配線を接続する直スリーブ接続部、8は配線、9は中継ケーブルである。なお図1では、配線8をはじめとして全ての線を1本の線で描いているが、実際は多数の線が使われて束ねられており、その全ての線について以下に説明するものと同じように取り扱う。
【0006】
既設制御盤1と新設制御盤2はそれぞれ入出力部のI/O4、6を介して外部と接続されるようになっている。当初の既設制御盤1はI/O4を介して配線8が接続され、配線8の他端は図示しない制御装置が接続されており、配線8を経由して既設制御盤1が制御装置を制御している。このようなシステムにおける制御盤の更新作業は、本発明の方法によると、図2のフローチャートに沿った次の手順によって行われる。
(ステップ1:S1)
まず初めに中継盤3を準備し、この中継盤3から既設制御盤1に2本の中継ケーブル9を配線する。中継盤3の2つの接点a、bのうち、aは閉じbは開いた状態にあり、それぞれの一端は互いに接続されている。2本の中継ケーブル9は接点aの両端子に接続される。
(ステップ2:S2)
2本の中継ケーブル9を、間をおいて、配線8に直スリーブ接続する。この時は、既設制御盤1は稼働中であってもよい。
(ステップ3:S3)
2ヶ所の直スリーブ接続部7の間を切断する。これによって、制御装置は配線8、直スリーブ接続部7、中継ケーブル9、中継盤3のa接点、中継ケーブル9、直スリーブ接続部7、の順に経由して既設制御盤1のI/O4に接続され、設備は稼動中のままである。
(ステップ4:S4)
既設制御盤1を、ステップ3の配線のまま退避場所に移設する。
(ステップ5:S5)
端子台5を備えた新設制御盤2を、当初の既設制御盤1があった場所に設置する。端子台5は中央端子を含む3端子を備え、中央端子と残る2端子の何れかが接続される。中央端子はI/O6に接続されている。
(ステップ6:S6)
端子台5の中央端子に接続されていない端子を制御装置に接続し、端子台5の中央端子に接続された端子を中継ケーブル9を介して中継盤3の接点bに接続する。接点bは開いているので、新設制御盤2のI/O6は制御装置に接続されていない状態にある。
(ステップ7:S7)
接点bを閉じる。これによって、新設制御盤2は、既設制御盤1と同様に中継盤3を介して制御装置に接続される。この状態で、新設制御盤2の動作チェックをし、既設制御盤1と比較して調整作業などを行う。
(ステップ8:S8)
端子台5を切替える。これによって新設制御盤2の I/O6は、中継盤3と中継ケーブル9を介することなく、配線8と端子台5を介して制御装置に接続される。この状態で新設制御盤2の動作の最終確認をする。問題があれば、最終調整をする。
(ステップ9:S9)中継盤5の接点bを開き、既設制御盤1と、中継盤3、中継ケーブル9を適宜撤去する。
このような手順によって既設制御盤1を新設制御盤2に置き換えるので、手際良く作業することができれば設備の稼動を停止することなく置換え作業を進めることができ、仮に設備の稼動停止をすることがあっても、各配線を接続する時と、各配線をはずす時に限られるので、下同定し時間を最小限に抑えることができるのである。
【0007】
【発明の効果】
以上述べたように、本発明によると、従来に比べ、設備の停止時間を最小に抑えることができ、設備の更新作業も最小にすることができる。また、実際の設備に即した試験をするので、試験を確実なものとすることができる。したがって、設備更新のためのコストを大幅に低減することができ、実用性を高められるという効果がある。

The terminal block 5 has three terminals including a central terminal, and one of the central terminal and the remaining two terminals is connected. The center terminal is connected to I / O6.
(Step 6: S6)
A terminal not connected to the center terminal of the terminal block 5 is connected to the control device, and a terminal connected to the center terminal of the terminal block 5 is connected to a contact b of the relay board 3 via the relay cable 9. Since the contact b is open, the I / O 6 of the newly installed control panel 2 is not connected to the control device.
(Step 7: S7)
Contact b is closed. Thus, the newly installed control panel 2 is connected to the control device via the relay panel 3 in the same manner as the existing control panel 1. In this state, the operation of the newly-installed control panel 2 is checked, and adjustment work and the like are performed in comparison with the existing control panel 1.
(Step 8: S8)
The terminal block 5 is switched. Thus, the I / O 6 of the newly installed control panel 2 is connected to the control device via the wiring 8 and the terminal block 5 without passing through the relay panel 3 and the relay cable 9. In this state, the final check of the operation of the new control panel 2 is performed. If there is a problem, make a final adjustment.
(Step 9: S9) The contact b of the relay panel 5 is opened, and the existing control panel 1, the relay panel 3, and the relay cable 9 are appropriately removed.
Since the existing control panel 1 is replaced with the new control panel 2 according to such a procedure, if the work can be performed swiftly, the replacement work can proceed without stopping the operation of the equipment, and the operation of the equipment can be temporarily stopped. Even if there is, only the time when each wiring is connected and the time when each wiring is disconnected can be identified and the time required for identification can be minimized.
[0007]
