In addition, since the piping inspection was performed manually to identify the leak location, the inspection load was heavy. In addition, when repairing a leak, the operation of the equipment may be stopped.

However, in the prior art, the supply path of compressed air cannot be flexibly changed, and when the occurrence of a leak is identified, it becomes necessary to stop the equipment.

　図５は、流体供給システム１０００の有するメッシュ配管回路８００における供給経路を説明する図である。
　図５の左上の図は、メッシュ配管回路８００の比較例の、ループ型配管である。ループ型の配管では、設備Ａから設備Ｄのうち設備Ｃのみ稼働（ＯＮ）し、設備Ａ，Ｂ，Ｄが停止（ＯＦＦ）の場合でも、ループ型配管の全域に圧縮空気を供給する必要がある。このため、停止している設備Ａ，Ｂ，Ｄのための経路にも圧縮空気が流れるため、この部分の圧縮空気の漏れが生じる。
　一方、実施の形態１のメッシュ配管回路８００では以下のようである。
　図５の左下の図は、メッシュ配管回路８００を模式的に示す。メッシュ配管回路８００は１６箇所の弁Ｖが配管８０２で接続されている。図５の左下の図は設備Ａから設備Ｄのすべてが停止している。
　図５の右上の図は、設備Ｃが稼働を開始した状態を示している。図５の右上の図では、弁Ｖ１の弁Ｖ２方向が開、弁Ｖ２の弁Ｖ３方向が開、弁Ｖ３の弁Ｖ４方向が開とされて、実線で示す供給経路が形成されている。この場合、図５の左上のループ型配管に対して、破線で示す部分には圧縮空気が供給されないため、ループ型配管に対して圧縮空気の漏れが少ない。
　図５の右下の図は、設備Ｂ、Ｃ、Ｄが稼働している状態を示す。右下の図では、右上の状態に加え、弁Ｖ４の弁Ｖ５方向が開、弁Ｖ５の弁Ｖ６方向が開、弁Ｖ５の弁Ｖ１０方向が開、弁Ｖ６の弁Ｖ７方向が開、弁Ｖ７の弁Ｖ８方向が開、弁Ｖ８の弁Ｖ９方向が開となったため、実線で示す圧縮空気の供給経路が形成された。図５の右下の図でも、メッシュ配管回路８００のうち破線の配管は使用されない。よって、ループ型配管に対して圧縮空気の漏れが少ない。 FIG. 5 is a diagram illustrating a supply path in the mesh piping circuit 800 included in the fluid supply system 1000.
The upper left figure of FIG. 5 is a loop type pipe of a comparative example of the mesh piping circuit 800. In the loop type piping, it is necessary to supply compressed air to the entire area of the loop type piping even when only the facility C of the facilities A to D is operating (ON) and the facilities A, B, and D are stopped (OFF). is there. Therefore, the compressed air also flows through the paths for the stopped facilities A, B, and D, so that the compressed air leaks in this portion.
On the other hand, in the mesh piping circuit 800 of the first embodiment, it is as follows.
The lower left figure of FIG. 5 schematically shows the mesh piping circuit 800. In the mesh piping circuit 800, 16 valves V are connected by piping 802. In the lower left figure of FIG. 5, all of equipment A to equipment D are stopped.
The upper right figure of FIG. 5 shows a state in which the facility C has started operation. In the upper right figure of FIG. 5, the valve V2 direction of the valve V1 is open, the valve V3 direction of the valve V2 is open, and the valve V4 direction of the valve V3 is open, and a supply path shown by a solid line is formed. In this case, since the compressed air is not supplied to the portion indicated by the broken line with respect to the loop type pipe on the upper left of FIG. 5, the leakage of the compressed air is small with respect to the loop type pipe.
The lower right figure of FIG. 5 shows a state in which facilities B, C, and D are in operation. In the lower right figure, in addition to the upper right state, the valve V5 direction of the valve V4 is open, the valve V6 direction of the valve V5 is open, the valve V10 direction of the valve V5 is open, the valve V7 direction of the valve V6 is open, and the valve V7. Since the valve V8 direction of the valve V8 was opened and the valve V9 direction of the valve V8 was opened, the supply path of the compressed air shown by the solid line was formed. Also in the lower right figure of FIG. 5, the broken line pipe in the mesh piping circuit 800 is not used. Therefore, there is less leakage of compressed air with respect to the loop type piping.

In step S26-1, the production execution system 230 transmits the valve control command 401 to the valve control unit 120 based on the determination result 780 received from the calculation instruction unit 111. The valve control command 401 may be the supply path 781 itself.
That is, when the data format of the supply path 781 is the opening / closing information of a plurality of valves forming the supply path 781 in the mesh piping circuit 800, the valve control command 401 may be the data of the supply path 781.

＊＊＊実施の形態１の効果の説明＊＊＊
（１）従来技術では、ループ配管における供給経路での圧縮空気のリークを許容しつつ、圧縮機の稼働制御により省エネルギー化を行っていた。しかし流体供給システム１０００では、メッシュ配管回路８００の備える弁の開閉を制御することで、メッシュ配管回路８００の一部分としての供給経路を形成する。
よって、本来使用しない配管の体積分への圧縮空気供給の削減及び圧縮空気の供給経路の最小化によるリーク削減が可能になる。
（２）流体供給システム１０００によれば、メッシュ配管回路８００により供給経路を最小化することができ、要求される圧縮空気量を従来よりも削減することができるため、圧縮機の稼働率を低減することが可能となるので、従来は達成できなかった省エネルギー化を図ることができる。 *** Explanation of the effect of Embodiment 1 ***
(1) In the prior art, energy saving is performed by controlling the operation of the compressor while allowing leakage of compressed air in the supply path in the loop piping. However, in the fluid supply system 1000, the supply path as a part of the mesh piping circuit 800 is formed by controlling the opening and closing of the valve provided in the mesh piping circuit 800.
Therefore, it is possible to reduce the supply of compressed air to the volume of the piping that is not originally used and to reduce the leakage by minimizing the supply path of the compressed air.
(2) According to the fluid supply system 1000, the supply path can be minimized by the mesh piping circuit 800, and the required compressed air amount can be reduced as compared with the conventional case, so that the operating rate of the compressor is reduced. This makes it possible to save energy, which was not possible in the past.
＜変形例＞
　図１６、図１７を参照して、実施の形態１の変形例を説明する。
図１６は、変形例における経路決定装置１００のハードウェア構成を示す。変形例の経路決定装置１００は、弁８０１の状態である弁状態情報１３１を記憶している弁状態記憶部１３０を備えている。弁状態記憶部１３０は、補助記憶装置３０で実現される。
図１７は、弁状態記憶部１３０が格納する弁状態情報１３１を示す。 <Modification example>
A modified example of the first embodiment will be described with reference to FIGS. 16 and 17.
FIG. 16 shows the hardware configuration of the routing device 100 in the modified example. The routing device 100 of the modified example includes a valve state storage unit 130 that stores valve state information 131 that is the state of the valve 801. The valve state storage unit 130 is realized by the auxiliary storage device 30.
FIG. 17 shows valve state information 131 stored in the valve state storage unit 130.
　図１７を参照して、弁状態情報１３１を説明する。破線で囲む範囲は、メッシュ配管回路８００の一部を示している。図１７では、弁は、Ｖ（１）、Ｖ（２）及びＶ（３）と表記し、配管は、Ｐ（１）、Ｐ（２）と表記し、圧力センサは、Ｓ（１）及びＳ（２）と表記している。
　また、Ｖ（１）は、サブバルブであるＶ（１）１及びＶ（１）２を有し、Ｖ（２）は、サブバルブであるＶ（２）１、Ｖ（２）２及びＶ（２）３を有し、Ｖ（３）は、サブバルブであるＶ（３）１、Ｖ（３）２及びＶ（３）３を有する。 The valve state information 131 will be described with reference to FIG. The area surrounded by the broken line shows a part of the mesh piping circuit 800. In FIG. 17, the valves are described as V (1), V (2) and V (3), the piping is described as P (1), P (2), and the pressure sensor is described as S (1) and S (1). It is written as S (2).
Further, V (1) has V (1) 1 and V (1) 2 which are sub-valves, and V (2) is V (2) 1, V (2) 2 and V (2) which are sub-valves. ) 3, V (3) has subvalves V (3) 1, V (3) 2 and V (3) 3.
　図１７の弁状態情報１３１は、Ｖ（１）２及びＶ（２）３が、閉固定の状態として記録されていることを示す。閉固定の列において、１は閉固定であることを示し、０は閉固定ではないことを示す。閉固定の場合、サブバルブは、閉じた状態としてみなされる。弁状態情報１３１の内容は、管理者が手動で弁状態記憶部１３０に登録してもよいし、実施の形態２の変形例で後述するように、配管計算部１１３Ａが、自動で弁状態記憶部１３０に登録してもよい。実施の形態１の変形例では、弁状態記憶部１３０に弁状態情報１３１が記憶されていれば、その記憶の方法は問わない。 The valve state information 131 of FIG. 17 indicates that V (1) 2 and V (2) 3 are recorded as a closed and fixed state. In the closed-fixed column, 1 indicates closed-fixed and 0 indicates not closed-fixed. When closed and fixed, the subvalve is considered closed. The contents of the valve state information 131 may be manually registered in the valve state storage unit 130 by the administrator, or the piping calculation unit 113A automatically stores the valve state as described later in the modified example of the second embodiment. It may be registered in the unit 130. In the modified example of the first embodiment, as long as the valve state information 131 is stored in the valve state storage unit 130, the method of storing the valve state information 131 does not matter.
　この変形例では、配管計算部１１３Ａは、ステップＳ２３－２で計算結果２として供給経路を決定する際に、弁状態情報１３１も参照して、供給経路を決定する。
　図１８は、配管計算部１１３Ａが、弁状態情報１３１も参照して、供給経路を決定することを説明する図であり図１４に対応する。図１８に示す弁状態情報１３１では、弁の列におけるＡ１，Ａ２，．．．は、図１のメッシュ配管回路８００のＡ，Ｂ，Ｃ，Ｄ，Ｅの位置の弁のサブバルブを示す。図１にはサブバルブを示す１，２，３を記載している。
　図１８の弁状態情報１３１では、サブバルブＢ１とサブバルブＤ２が閉固定である。この場合は、配管計算部１１３Ａは、供給経路を決定する際に、サブバルブＢ１とサブバルブＤ２とを使用する供給経路を採用しない。よって、配管計算部１１３Ａは、図１４で述べた経路Ａ→Ｂ→Ｄ→Ｅ→Ｃは採用しない。図１８の例では、配管計算部１１３Ａは、洗浄機２号機の経路として経路Ａ→Ｂ→Ｃ→Ｅを採用する。 In this modification, when the piping calculation unit 113A determines the supply path as the calculation result 2 in step S23-2, the piping calculation unit 113A also refers to the valve state information 131 to determine the supply path.
FIG. 18 is a diagram for explaining that the piping calculation unit 113A determines the supply path with reference to the valve state information 131, and corresponds to FIG. In the valve state information 131 shown in FIG. 18, A1, A2, in the valve row. .. .. Shows the sub-valves of the valves at the positions A, B, C, D, and E of the mesh piping circuit 800 of FIG. In FIG. 1, 1, 2 and 3 showing sub valves are shown.
In the valve state information 131 of FIG. 18, the sub valve B1 and the sub valve D2 are closed and fixed. In this case, the piping calculation unit 113A does not adopt the supply path that uses the sub valve B1 and the sub valve D2 when determining the supply path. Therefore, the piping calculation unit 113A does not adopt the route A → B → D → E → C described in FIG. In the example of FIG. 18, the piping calculation unit 113A adopts the route A → B → C → E as the route of the washing machine No. 2.
＊＊＊変形例の効果＊＊＊
　実施の形態１の変形例では、供給経路の決定の際に弁状態情報１３１を使用することで、配管計算部１１３Ａは、弁が閉固定のため採用できない供給経路をすぐに判定できる。よって、配管計算部１１３Ａは迅速に供給経路を決定することができる。 *** Effect of modified example ***
In the modified example of the first embodiment, by using the valve state information 131 when determining the supply path, the piping calculation unit 113A can immediately determine the supply path that cannot be adopted because the valve is closed and fixed. Therefore, the piping calculation unit 113A can quickly determine the supply route.

（５）診断部である配管計算部１１３Ａは、流体が閉じ込められた配管に配置された圧力センサからセンサデータを取得し、取得したセンサデータと、基準データとを比較することにより流体が閉じ込められた配管の流体漏れを診断する。具体的には以下のようである。ステップＳ４６において、配管計算部１１３Ａは、孤立状態のセンサＳ４のセンサデータを、リークを判定するための基準データと比較し、配管Ｂ４のリーク診断を行う。データは例えば図９に示す消費量である。リーク診断として、配管計算部１１３Ａは、センサデータを図９に示す配管の消費量に換算し、図９の消費量を基準データとして用いて診断する。
（６）ステップＳ４７において、配管計算部１１３Ａは、診断の結果、配管Ｂ４でリーク発生と判定した場合、配管ＤＢ１１３Ｂに配管Ｂ４の消費量を９９ｍ３／秒と記録する。
　図２１は、配管計算部１１３Ａが、配管ＤＢ１１３Ｂに配管Ｂ４の消費量を記録する動作を示す。
　配管Ｂ４でリーク発生が発生しない場合、配管Ｂ４の圧縮空気の消費量は、０．０１ｍ３／秒である。配管計算部１１３Ａは、配管Ｂ４でリーク発生と判定した場合、図２１に示すように、配管Ｂ４の圧縮空気の消費量を、０．０１ｍ３／秒から９９ｍ３／秒へ更新する。
９９ｍ３／秒の意味は、リーク発生が発生しない場合の消費量である０．０１ｍ３／秒に対して、実際には無限大に等しい極端に大きい値の意味である。０．０１ｍ３／秒に対して極端に大きい値であれば、どのような値でもよい。
（７）診断部である配管計算部１１３Ａは、メリーク発生と診断した配管を含む供給経路を採用しない。
　具体的には以下のようである。以下の動作は、実施の形態１の経路決定装置１００も同様の動作である。
　ステップＳ４８において、経路決定装置１００の配管計算部１１３Ａは、実施の形態１で述べたように供給経路の採用を決定する。配管計算部１１３Ａは、採用しようとする供給経路を選択する。その際、配管計算部１１３Ａは、選択された供給経路に含まれる複数の配管の合計の圧縮空気の消費量を、配管ＤＢ１１３Ｂの有する圧縮空気の消費量を参照して計算する。例えば、選択された供給経路に３本の配管が含まれ、どの配管も圧縮空気の消費量が０．０１ｍ３／秒とする。その場合、３本の配管の合計の圧縮空気の消費量は、０．０３ｍ３／秒である。また、仮に供給経路に１０００本の配管が含まれているとしても、合計の消費量は、０．０１ｍ３／秒の１０００倍の１０ｍ３／秒である。
　一方、選択された供給経路に、リーク発生と判定された配管が１つでも含まれる場合、供給経路の圧縮空気の消費量の合計は、９９ｍ３／秒を超える。配管計算部１１３Ａは、供給経路の圧縮空気の消費量の合計が９９ｍ３／秒を超える場合、その供給経路を採用しない。つまり、配管計算部１１３Ａは、その供給経路を計算結果２に含めない。 (1) At the start of the diagnosis in step S42, the valve control unit 120 opens the valve V2 in the directions of the valve V50, the valve V99, and the branch 4.
(2) In step S43, the pressure sensor S4 arranged in the pipe B4 transmits the sensor data to the pipe calculation unit 113A.
(3) The valve control unit 120 controls at least one of the plurality of valves with respect to the mesh piping circuit 800, so that a pressure sensor is arranged and the fluid flows into the piping to which the solenoid valves are connected at both ends. At the same time, the solenoid valves at both ends of the pipe are kept closed to confine the fluid in the pipe. Specifically, it is as follows. In step S44, the valve control unit 120 closes the valve V2.
The pipe B4 is isolated.
(4) In step S45, the pressure sensor S4 transmits the sensor data of the pipe B4 in the isolated state to the pipe calculation unit 113A.
(5) The piping calculation unit 113A, which is a diagnostic unit, acquires sensor data from a pressure sensor arranged in a pipe in which the fluid is confined, and compares the acquired sensor data with the reference data to confine the fluid. Diagnose fluid leaks in pipes. Specifically, it is as follows. In step S46, the pipe calculation unit 113A compares the sensor data of the sensor S4 in the isolated state with the reference data for determining the leak, and performs the leak diagnosis of the pipe B4. The data is, for example, the consumption shown in FIG. As a leak diagnosis, the pipe calculation unit 113A converts the sensor data into the consumption amount of the pipe shown in FIG. 9, and diagnoses using the consumption amount of FIG. 9 as the reference data.
(6) In step S47, when it is determined that a leak has occurred in the pipe B4 as a result of the diagnosis, the pipe calculation unit 113A records the consumption amount of the pipe B4 as 99 m 3 / sec in the pipe DB 113B.
FIG. 21 shows an operation in which the pipe calculation unit 113A records the consumption amount of the pipe B4 in the pipe DB 113B.
If no leak occurs in the pipe B4, the consumption of compressed air in the pipe B4 is 0.01 m 3 / sec. When the pipe calculation unit 113A determines that a leak has occurred in the pipe B4, the pipe calculation unit 113A updates the consumption of compressed air in the pipe B4 from 0.01 m 3 / sec to 99 m 3 / sec, as shown in FIG.
The meaning of 99 m 3 / sec is an extremely large value that is actually equal to infinity with respect to the consumption of 0.01 m 3 / sec when no leak occurs. Any value may be used as long as it is extremely large with respect to 0.01 m 3 / sec.
(7) The piping calculation unit 113A, which is a diagnostic unit, does not adopt a supply route including a pipe diagnosed as having a merry-kick.
Specifically, it is as follows. The following operations are the same for the routing device 100 of the first embodiment.
In step S48, the piping calculation unit 113A of the route determination device 100 determines the adoption of the supply route as described in the first embodiment. The piping calculation unit 113A selects the supply route to be adopted. At that time, the pipe calculation unit 113A calculates the total consumption of compressed air of the plurality of pipes included in the selected supply path with reference to the consumption of compressed air of the pipe DB 113B. For example, the selected supply path includes three pipes, each of which consumes 0.01 m 3 / sec of compressed air. In that case, the total consumption of compressed air in the three pipes is 0.03 m 3 / sec. Further, even though it contains if 1,000 pipes the feed path, the consumption of total is 10 m 3 / sec 1000 times 0.01 m 3 / sec.
On the other hand, if the selected supply path includes at least one pipe determined to have leaked, the total consumption of compressed air in the supply path exceeds 99 m 3 / sec. If the total consumption of compressed air in the supply path exceeds 99 m 3 / sec, the piping calculation unit 113A does not adopt the supply path. That is, the piping calculation unit 113A does not include the supply route in the calculation result 2.

　図２２を参照して、配管計算部１１３Ａによる弁状態情報１３１の作成を説明する。配管計算部１１３Ａは、ステップＳ４６で、配管Ｂ４でリーク発生と判定した場合、図２２に示すように、配管Ｂ４の両端のサブバルブであるＶ２－２と、Ｖ５－１の閉固定の値を１に設定する。
　一方、配管計算部１１３Ａは、ステップＳ４６で、配管Ｂ４でリーク発生なしと判定した場合、サブバルブであるＶ２－２と、Ｖ５－１の閉固定の値を０に設定する。
　以上により、弁状態情報１３１が自動的に生成される。また、上記の動作を適宜実施することで、診断装置９０１は弁状態情報１３１を自動で更新することができる。 With reference to FIG. 22, the creation of the valve state information 131 by the piping calculation unit 113A will be described.

Set to.
On the other hand, when the piping calculation unit 113A determines in step S46 that no leak has occurred in the piping B4, the closed / fixed values of the sub valves V2-2 and V5-1 are set to 0.
As a result, the valve state information 131 is automatically generated. Further, by appropriately performing the above operation, the diagnostic apparatus 901 can automatically update the valve state information 131.
＊＊＊実施の形態２の効果の説明＊＊＊
（１）従来技術では、圧力センサにより、固定された圧縮空気の供給経路におけるリーク箇所を特定していたが、圧縮空気を消費する設備の稼働状況により、リーク判定誤差が避けられなかった。
しかし、実施の形態２の診断システム９００によれば、メッシュ配管回路８００において、新たに隔離もしくは新たに拡張されたノードの圧力変化を、正常時の圧力データと比較することで特定することができる。
（２）また、診断システム９００によれば、メッシュ配管回路８００において、圧縮空気の供給経路を動的に変更できるので、診断によってリークが発見された配管を迂回したリークの少ない供給経路を提供できる。 *** Explanation of the effect of Embodiment 2 ***
(1) In the conventional technique, a leak location in a fixed compressed air supply path is specified by a pressure sensor, but a leak determination error cannot be avoided depending on the operating status of equipment that consumes compressed air.
However, according to the diagnostic system 900 of the second embodiment, in the mesh piping circuit 800, the pressure change of the newly isolated or newly expanded node can be specified by comparing with the normal pressure data. ..
(2) Further, according to the diagnostic system 900, since the supply path of the compressed air can be dynamically changed in the mesh piping circuit 800, it is possible to provide a supply path with less leakage that bypasses the piping in which the leak is found by the diagnosis. ..
