The communication terminal 10 may be connected to another communication terminal 300 or a control system, and may transmit and receive data from the communication terminal 10 to each other.
診断装置６０は、各種センサが検知したデータを受信し、記憶部６２に受信したデータを蓄積する。蓄積したデータは、例えば、図３、図４に示すようなテーブルで、受信した時間、日付とともに、各センサから受信した結果を蓄積する。 The diagnostic device 60 receives data detected by various sensors and accumulates the received data in the storage unit 62. The accumulated data is, for example, a table as shown in FIGS. 3 and 4, and the results received from each sensor are accumulated together with the received time and date.
そして、診断装置６０は、新たに受信したデータを、記憶部６２に蓄積されたデータと比較分析を行う。ここでの比較分析の一例として、例えば、ある配管部材が特定のバルブで過去のデータを蓄積し、その特定のバルブから新たに受信したデータが、振動センサ、歪センサが検知した情報で「異常あり」（地震等が発生したなどの理由で）である場合は、図３の11時のデータと同一であると分析し、11時15分以降に発生するように、漏液が始まる可能性がある。そこで、故障予測として、漏液が今後、発生する可能性があることを予測する。 Then, the diagnostic device 60 performs a comparative analysis of the newly received data with the data accumulated in the storage unit 62. As an example of the comparative analysis here, for example, a certain piping member accumulates past data with a specific valve, and newly received data from the specific valve is the information detected by the vibration sensor and the strain sensor. If it is “Yes” (because of an earthquake, etc.), it is analyzed that it is the same as the data at 11:00 in FIG. There is. Therefore, as a failure prediction, it is predicted that liquid leakage may occur in the future.
また、劣化判定の一例としては、例えば、上記の特定のバルブで、新たに受信したデータが、圧力センサが前日よりも、０．１Ｐａ減ったと検知した場合は、図４の4月9日のデータと同一の可能性があると分析し、配管部材が劣化している可能性があり、漏液する可能性があることを判定する。 Further, as an example of the deterioration determination, for example, when the newly received data is detected by the above-described specific valve that the pressure sensor has decreased by 0.1 Pa from the previous day, April 9 in FIG. It is analyzed that there is a possibility that it is the same as the data, and it is determined that there is a possibility that the piping member has deteriorated and there is a possibility of leakage.
診断装置６０は、これらの故障予測や劣化判定の結果を、通信端末１０に送信して、出力する。出力例としては、予めこれらの故障予測や劣化判定の結果と、メッセージやアイコン等を予め対応付けておいて、この結果の時にメッセージ等を表示してよい。メッセージとしては、例えば、「バルブに振動と歪みを検知したために、過去の経験では漏液する可能性が高いです」、「バルブが劣化しているため、近日中に漏液する可能性があります」を表示する。 The diagnostic device 60 transmits the results of failure prediction and deterioration determination to the communication terminal 10 and outputs them. As an output example, the result of failure prediction or deterioration determination may be associated with a message, an icon, or the like in advance, and a message or the like may be displayed at the result. Examples of messages include: “Since the vibration and strain were detected in the valve, there is a high possibility of leaking in the past experience”, “Since the valve has deteriorated, there is a possibility of leaking in the near future. Is displayed.
上述のように故障予測、劣化判定を行った場合には、故障や劣化が発生したため、何らかの対応が必要となり、所定の対策を行うことが望ましい。ここで、例えば、配管部材がバルブ５０の場合は、ひとまずは、バルブ５０の開閉を行ってみて、故障や劣化が本当に発生しているか、様子を見てみたいことがある。そこで、以下ではバルブ５０が、自動バルブの場合に、通信端末１０から操作者がバルブ５０の開閉を行うことについて説明する。 When failure prediction and deterioration determination are performed as described above, failure or deterioration has occurred, so some kind of response is necessary, and it is desirable to take predetermined measures. Here, for example, when the piping member is the valve 50, it may be desirable to first check whether the failure or deterioration has actually occurred by opening and closing the valve 50. Therefore, hereinafter, when the valve 50 is an automatic valve, it will be described that the operator opens and closes the valve 50 from the communication terminal 10.
診断装置６０は、配管部材がバルブ５０であって、バルブ５０が自動バルブの場合は、開スイッチ４０、閉スイッチ４１に所定の信号を送信することで、自動バルブの弁の開閉を行うことができる。ここで、自動バルブの開閉は、弁が回転または上下動することで行われるため、回転の場合には角度センサ及びリミットスイッチの回転位置情報から、また、上下動の場合には位置センサ及びリミットスイッチの上下動位置情報から、弁の開き具合である開度が決定する。 When the piping member is the valve 50 and the valve 50 is an automatic valve, the diagnostic device 60 can open and close the valve of the automatic valve by transmitting a predetermined signal to the open switch 40 and the close switch 41. it can. Here, since the automatic valve is opened and closed by rotating or moving up and down, the rotational position information of the angle sensor and limit switch is used for rotation, and the position sensor and limit are used for vertical movement. The opening degree that is the degree of opening of the valve is determined from the vertical movement position information of the switch.
図５は、通信端末１０が画面表示した際の、画面イメージ図である。図５に示すように、例えば、Ａ型ＶＡＬＶＥ、Ｂ型ＶＡＬＶＥ、Ｃ型ＶＡＬＶＥなどのいくつかのバルブのうち、操作者は、所定のバルブを選択し、バルブ毎に無効、有効等の入力操作を行い、全開または全閉の選択や、開度コントロール８０で開度の調整を行う。すなわち、開度コントロール８０の操作スイッチ８１を左右に操作することで、開度を何％にするかを決定できる。通信端末１０は、決定された開度を診断装置６０に送信し、診断装置６０が自動バルブに開閉信号を送信する。この信号を受信した自動バルブが物理的にバルブの開閉を行う。 FIG. 5 is a screen image diagram when the communication terminal 10 displays the screen. As shown in FIG. 5, for example, among several valves such as A-type VALVE, B-type VALVE, and C-type VALVE, the operator selects a predetermined valve and performs input operations such as invalid and valid for each valve. And the opening degree is adjusted by the opening degree control 80. That is, by operating the operation switch 81 of the opening degree control 80 to the left and right, it is possible to determine what percentage the opening degree is. The communication terminal 10 transmits the determined opening degree to the diagnostic device 60, and the diagnostic device 60 transmits an open / close signal to the automatic valve. The automatic valve that receives this signal physically opens and closes the valve.
そして、実際の開度は、現在値モニター８２の数値で入力操作した値と同一であるか、確認することが可能である。この場合、例えば、操作者が６０％と開度を操作しているにもかかわらず、現在値が７５％で停止してしまえば、このバルブが故障していることを予測できる。また、バルブの開閉回数８３は、診断装置６０のカウンタ部６７がバルブから信号を受信して、カウントし、その結果を通信端末１０に表示する。さらに、稼働時間８４は、診断装置６０のタイマ部６６がバルブから信号を受信して、計時し、その結果を通信端末１０に表示する。なお、自動バルブが「開く」動きをすべきか、「閉まる」動きをすべきかは、自動バルブの現在値の開度と、操作者が、今、入力操作した開度数値の大小によって決定されるにすぎない。すなわち、現在値の開度（例えば、６０％）が入力操作された開度（例えば、７５％）よりも小さければ、「開く」動きの信号を送出するし、現在値の開度（例えば、７５％）が入力操作された開度（例えば、６０％）よりも大きければ、「閉まる」動きの信号を送出する。 Then, it is possible to confirm whether the actual opening is the same as the value input by the numerical value of the current value monitor 82. In this case, for example, if the current value is stopped at 75% even though the operator operates the opening at 60%, it can be predicted that the valve is broken. The valve opening / closing count 83 is counted by the counter unit 67 of the diagnostic device 60 receiving a signal from the valve and displaying the result on the communication terminal 10. Furthermore, the operating time 84 is measured by the timer unit 66 of the diagnostic device 60 receiving a signal from the valve and displaying the result on the communication terminal 10. Whether the automatic valve should be "opened" or "closed" is determined by the opening of the current value of the automatic valve and the magnitude of the numerical value of the opening currently input by the operator. Only. That is, if the opening of the current value (for example, 60%) is smaller than the input opening (for example, 75%), an “open” movement signal is transmitted, and the opening of the current value (for example, 75%) is larger than the input opening degree (for example, 60%), a “closed” movement signal is transmitted.
上記の実施の形態によれば、過去の配管部材の劣化に関する蓄積データを利用することで、配管部材の故障予測や劣化判定を行うことが可能となり、操作者が配管部材の状況を知り、操作することが可能となる。 According to the above embodiment, it is possible to perform failure prediction and deterioration determination of the piping member by using accumulated data related to deterioration of the piping member in the past. It becomes possible to do.
