【0003】 次に動作について説明する。 [0003] Next, the operation will be described. プラント設備に設置した複数の設備機器3と接続 し、これらを監視制御する複数の端末装置は、複数の各設備器機器3を統括監視 制御する中央処理装置1に接続される。 Connected to a plurality of equipment 3 installed in the plant facilities, a plurality of terminal devices for controlling them monitor is connected to the central processing unit 1 which integrally monitoring and controlling a plurality of the respective equipment devices devices 3. 中央処理装置1は端末装置2と通信をお こない、設備機器3を直接監視制御している端末装置2に関する各種監視制御情 報を収集すると共に、中央処理装置1から端末装置2に制御情報を送出して、中 央処理装置1により端末装置2と設備機器3の中央監視制御をおこなう。 The central processing unit 1 is not you this communication with the terminal device 2, as well as collects various monitoring control information on the terminal device 2 that controls monitoring equipment 3 directly, the control information from the central processing unit 1 to the terminal device 2 delivery, by Chuo processing apparatus 1 and terminal apparatus 2 performs central monitoring and control of the equipment 3. また、設備機器3のメンテナンス等の時に、中央処理装置1よりメンテナンス 中の設備機器3を監視制御の対象外に設定し保守中とすることができる。 Further, it is possible at the time of maintenance or the like of the equipment 3, to set the equipment 3 in maintenance from the central processing unit 1 excluded from the monitoring control and during maintenance. 保守中 の機器の状態信号は中央処理装置で無視される。 State signal of the device in the maintenance is ignored by the central processing unit.

【0004】 [0004]

【考案が解決しようとする課題】 [Challenges devised to be Solved]

従来のプラント監視装置は以上にように構成されているので、設備機器3の状 態信号送信部12が故障し、状変信号を次々と送信している場合、中央処理装置1 より保守設定を行うまで、中央処理装置1及び通信の負荷が大きくなってしまい 他の設備機器の監視制御が出来にくくなるという問題点があった。 Since the conventional plant monitoring device is constructed as above, it failed state signal transmitter 12 of the equipment 3, if you are one after another sends a state change signals, the maintenance settings from the central processing unit 1 carried out until there has been a problem that the load of the central processing unit 1 and the communication is not easily able to monitor and control other equipment becomes large.

【0005】 この考案は上記のような課題を解決するためになされたものであり、設備機器 の状態信号送信部の故障を自動的に検出できるとともに、状態信号送信部の故障 時、状態信号を無視するプラント監視装置を得ることを目的とする。 [0005] This invention has been made to solve the above problems, along with automatically detect the failure of the status signal transmitter of the equipment, failure of the status signal transmitter, a status signal and to obtain a plant monitoring device to ignore.

【0006】 [0006]

【課題を解決するための手段】 In order to solve the problems]

この考案に係るプラント監視装置は、状態信号送信部故障時に自動的に保守設 定を行う異常信号検出部を備えたものである。 Plant monitoring apparatus according to this invention are those having the abnormal signal detection unit that performs automatic maintenance setting when the state signal transmitter failure.

【0007】 [0007]

【作用】 [Action]

この考案におけるプラント監視装置の異常信号検出部は、状態信号送信部故障 時に自動的に保守設定を行い状態信号を無視する。 Abnormal signal detection unit of the plant monitoring apparatus in the invention ignores the status signal performs status signal transmitter fault automatically when maintenance settings.

【0008】 [0008]

【実施例】 【Example】

実施例1. Example 1. 以下、この考案の実施例1によるプラント監視装置を図について説明する。 Hereinafter, FIG explained the plant monitoring apparatus according to a first embodiment of this invention. 図 1において1は、中央処理装置、2は端末、3は設備機器、4はディスプレイ装 置、5はプリンタ装置、6はキーボード、7は状変処理部、8は異常信号検出部 、9はキー入力読解部、10は保守設定処理部、11は機器監視部、12は状態信号送 信部である。 1 In FIG. 1, a central processing unit, 2 terminal, 3 equipment, the display equipment 4, 5 printer, a keyboard 6, 7 state change processing unit, 8 abnormal signal detection unit, the 9 key input reading unit, 10 maintenance setting processing unit, 11 device monitoring unit, 12 is a signal unit transmission state signal.

【0009】 次に動作について説明する。 [0009] Next, the operation will be described. 状態信号送信部12が故障し状変信号が次々と送信 された場合、異常信号検出部8において一定時間内の信号の数をカウントし、一 定数以上の信号が送信された時、状態信号送信部8の故障と判定し、故障のあっ た機器3に対し保守設定を行う。 If the state signal transmitter 12 is faulty state change signal is transmitted one after another, counting the number of signals in a predetermined time in the abnormality signal detecting unit 8, when the above signal one constant has been transmitted, the state signal transmitted determining a failure of the part 8 performs maintenance settings to device 3 for which the fault. 保守設定された機器3の状態信号は中央処理装 置で無視されるので、他の設備機器の監視制御への影響をなくする。 SERVICE state signals of the device 3 since it is ignored by the central processing equipment, eliminating the influence on the supervisory control of other equipment.

【0010】 実施例2. [0010] Example 2. 図2はこの考案の実施例によるプラント監視装置を示す図であり、異常信号検 出部8を端末に持たせ、端末装置2側で故障を検出してもよい。 Figure 2 is a diagram illustrating the plant monitoring apparatus according to an embodiment of this invention, an abnormal signal detection unit 8 to have the terminal may detect a fault in the terminal apparatus 2 side. この場合、状態 信号送信部12に故障が発生しても対象機器を監視制御している端末装置2のみで 処理ができるので、中央処理装置1、端末装置2、中央処理装置1と端末装置2 間の通信に影響を及ぼすことはない。 In this case, since the failure state signal transmitting unit 12 can terminal device 2 only in the process that monitors and controls target devices be generated, the central processing unit 1, the terminal device 2, the central processing unit 1 and the terminal apparatus 2 It does not affect the communication between.
