特開2009−192340号公報JP 2009-192340 A

飲料水の水質は、昼夜を問わず24時間連続で監視して省令で定められている基準値以内であることを確保し、一般住民が安心して利用できる管理体制を常時維持しなければならい。そのためには、水道水等の水質を連続的に計測する水質連続計測装置は、24時間体制の維持管理が求められ、常日頃の点検や定期的に行う保守点検等に莫大な維持管理費用を要しているのが現状である。   The quality of drinking water must be continuously monitored 24 hours a day, 24 hours a day, to ensure that it is within the standard values set by the Ministerial Ordinance, and to maintain a management system that can be used with peace of mind by the general population. For this purpose, a continuous water quality measuring device that continuously measures the quality of tap water, etc., requires 24 hour maintenance, and requires huge maintenance costs for regular inspections and regular maintenance inspections. What is needed is the current situation.

前述した従来技術では、計測値異常が一定時間継続した際に異常検知信号を発生させて遠隔地の管理センターへ報知することで24時間体制の維持管理の実現を可能にしているが、異常発生の報知を受けた後の修理等は人的な作業に頼っているのが現状である。水道水の水質を計測する水質連続計測装置は、人里離れた無人の施設で遠隔監視されていることが多く、運転中の装置に万が一不具合が発生した場合には、夜中であっても休祭日であっても速やかに遠隔地まで専門の作業員を派遣しなければならず、専門作業員の常時待機にかかる人件費や遠隔地までの移動に要する経費等に多大な費用がかかる問題があった。   In the above-described conventional technology, it is possible to realize 24-hour maintenance management by generating an abnormality detection signal when a measurement value abnormality continues for a certain period of time and notifying the remote management center. The present situation is that the repair after receiving the notification depends on human work. Water quality continuous measurement devices that measure the quality of tap water are often remotely monitored at unmanned facilities that are remote, and in the unlikely event that a malfunction occurs in a device that is in operation, it will be suspended even at night. Even if it is a national holiday, specialist workers must be dispatched to remote locations as soon as possible, and there is a problem that labor costs for constant waiting for specialized workers and expenses required for moving to remote locations are very expensive. there were.

また、水質連続計測装置の設置箇所が管理センターから離れた遠隔地にある場合には、異常発生の報知を受けてから対処に当たるまでに長時間を要することになるので、その間の水質監視が途絶えてしまう問題がある。これに対処するには、装置の状態の良し悪しに拘わらず、定期的な保守点検を頻繁に行わざるを得ず、全国津々浦々に設置されている水質連続計測装置に対して作業員を派遣して行う定期的な点検には毎回高額な費用がかかり、これを頻繁に行うためには莫大な維持管理費用がかかる問題があった。   In addition, if the location where the continuous water quality measuring device is installed is in a remote location away from the management center, it will take a long time to receive a response after receiving the notification of the occurrence of an abnormality. There is a problem. To deal with this, regular maintenance and inspection must be carried out frequently regardless of the condition of the equipment, and workers are dispatched to the continuous water quality measuring equipment installed throughout the country. Regular inspections carried out in this manner are expensive, and there is a problem that enormous maintenance costs are required to do this frequently.

本発明は、このような問題に対処することを課題の一例とするものである。すなわち、水道水等の水質(濁度・色度等)を連続的に計測する水質連続計測装置において、異常発生時に即座に正常な状態への対処を行うことができること、専門の作業員の到着を待たずして簡易に正常な状態への対処を行うことができること、24時間体制の維持管理を行うに際して、大幅な維持管理費用の削減を可能にすること、定期な保守点検を排除することができること、等が本発明の目的である。   This invention makes it an example of a subject to cope with such a problem. In other words, in a continuous water quality measuring device that continuously measures the quality of water such as tap water (turbidity, chromaticity, etc.), it is possible to deal with normal conditions immediately when an abnormality occurs, and the arrival of specialized workers It is possible to easily cope with the normal state without waiting for it, to enable a significant reduction in maintenance costs when performing 24-hour maintenance management, and to eliminate periodic maintenance inspections It is an object of the present invention to be able to.

このような目的を達成するために、本発明による水質連続計測装置は、以下の構成を少なくとも具備するものである。   In order to achieve such an object, a water quality continuous measurement apparatus according to the present invention comprises at least the following configuration.

試料水が流入する流入流路が接続されると共に流入した試料水を排水する排水流路が接続されたフローセルと該フローセルに流入した試料水の水質評価指標に係る検出信号を出力する検出部とを備えた検出ユニットを複数備え、複数の前記検出ユニットがそれぞれ備えるフローセルに接続された複数の流入流路に対して、試料水源から試料水を供給する試料水供給流路を備え、複数の前記流入流路の中の一つのみを前記試料水供給流路に連通させる流路選択手段を備え、前記検出部の検出信号を演算処理する演算処理部を備えたことを特徴とする水質連続計測装置。 A flow cell to which an inflow channel into which the sample water flows is connected and a drain channel to drain the sample water that has flowed in, and a detection unit that outputs a detection signal relating to a water quality evaluation index of the sample water that has flowed into the flow cell; A plurality of detection units, each of which includes a plurality of inflow passages connected to flow cells included in each of the plurality of detection units, a sample water supply channel for supplying sample water from a sample water source, Water quality continuous measurement characterized by comprising a flow path selection means for communicating only one of the inflow flow paths to the sample water supply flow path, and comprising an arithmetic processing section for arithmetic processing of the detection signal of the detection section. apparatus.

本発明は、このような特徴を有することで、水道水等の水質(濁度・色度等)を連続的に計測する水質連続計測装置において、装置自身が備える演算処理部によって装置の異常が検知された場合等に、複数の検出ユニットのうち使用中のものから新たな検出ユニットに切り替えられて検出動作が継続される。これによって、自動で検出ユニットの切り替えを行う場合には異常発生時に即座に正常な状態への対応を行うことができ、手動で検出ユニットの切り替えを行う場合には専門の作業員の到着を待たずして簡易に正常な状態への対処を行うことができる。また、異常が検知されたことは遠隔監視できるので、異常発生時のみ不良検出ユニットの取り替え作業を行えば良く、定期的な保守点検を排除することができ、24時間体制の維持管理を行うに際して、大幅な維持管理費用の削減を可能にする。   Since the present invention has such characteristics, in the water quality continuous measurement device that continuously measures the water quality (turbidity, chromaticity, etc.) of tap water, the abnormality of the device is detected by the arithmetic processing unit provided in the device itself. When it is detected, the detection operation is continued by switching from the one in use among the plurality of detection units to a new detection unit. As a result, when the detection unit is automatically switched, it is possible to immediately respond to the normal state when an abnormality occurs, and when manual switching of the detection unit is performed, a specialized worker waits for arrival. Therefore, it is possible to easily deal with a normal state. In addition, since it can be remotely monitored that an abnormality has been detected, it is only necessary to replace the defect detection unit only when an abnormality has occurred, and periodic maintenance and inspection can be eliminated. Enables significant maintenance cost savings.

以下、図面に基づいて本発明の実施形態を説明する。図1は本発明の一実施形態に係る水質連続計測装置の基本構成を示した説明図である。水質連続計測装置1は、複数の検出ユニット10,10,…、試料水供給流路20、流路選択手段30、演算処理部40等を備えている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing a basic configuration of a continuous water quality measuring apparatus according to an embodiment of the present invention. The water quality continuous measurement apparatus 1 includes a plurality of detection units 10, 10,..., A sample water supply channel 20, a channel selection means 30, an arithmetic processing unit 40, and the like.

複数の検出ユニット10,10,…は図示の例では2つ備えているが、2つ以上備えていれば良い。各検出ユニット10は、フローセル11と検出部12を少なくとも備えている。フローセル11には試料水が流入する流入流路13と流入した試料水を排水する排水流路14が接続されている。検出部12は、フローセル11に流入した試料水の水質評価指標に係る検出信号を出力するものであればよく、例えば、試料水の濁度,色度,pH,塩素濃度等を検出することができればよい。図示の例では、検出部12として、フローセル11内に光を投光する光源部12Aとフローセル11を透過した光を検出する受光部12Bとを備えており、光学的に試料水の水質評価指標(例えば、濁度と色度の一方又は両方)を検出することができるものである。   The plurality of detection units 10, 10,... Are provided in the illustrated example, but may be provided with two or more. Each detection unit 10 includes at least a flow cell 11 and a detection unit 12. The flow cell 11 is connected with an inflow channel 13 into which sample water flows and a drain channel 14 through which the sample water flows. The detection unit 12 only needs to output a detection signal related to the water quality evaluation index of the sample water flowing into the flow cell 11. For example, the detection unit 12 can detect turbidity, chromaticity, pH, chlorine concentration, and the like of the sample water. I can do it. In the illustrated example, the detection unit 12 includes a light source unit 12A that projects light into the flow cell 11 and a light receiving unit 12B that detects light transmitted through the flow cell 11, and optically evaluates the water quality of the sample water. (For example, one or both of turbidity and chromaticity) can be detected.

試料水供給流路20は、試料水源から流入流路13に試料水を供給するためのものである。図示の例では、試料水供給流路20は、試料水源に繋がる1本の流路21が多岐(二本)の流路22,23に分岐しており、分岐された流路22,23がそれぞれ異なる検出ユニット10,10における流入流路13(131),13(132)に接続している。試料水供給流路20(22,23)と流入流路13(131),13(132)とは着脱自在なカプラ(ワンタッチカプラ)24,25で互いに接続されている。排水流路14の端部にもカプラ(ワンタッチカプラ)26が設けられ、排水用の末端流路に接続されている。 The sample water supply channel 20 is for supplying sample water from the sample water source to the inflow channel 13. In the example shown in the drawing, the sample water supply channel 20 has one channel 21 connected to the sample water source branched into a variety of (two) channels 22, 23, and the branched channels 22, 23 are The inflow channels 13 (13 1 ) and 13 (13 2 ) in the different detection units 10 and 10 are connected. The sample water supply channel 20 (22, 23) and the inflow channels 13 (13 1 ), 13 (13 2 ) are connected to each other by detachable couplers (one-touch couplers) 24, 25. A coupler (one-touch coupler) 26 is also provided at the end of the drainage channel 14 and is connected to the drainage end channel.

流路選択手段30は、試料水供給流路20と複数の検出ユニット10,10における流入流路13(131),13(132)とを選択的に連通するものである。ここで選択的に連通するというのは、試料水供給流路20(21,22,23)が一つの流入流路13(131)と連通している場合には他の流入流路13(132)とは連通しないという意味である。図示の例では、流路選択手段30は、流入流路13(131),13(132)に対して装備され、これら流入流路13(131),13(132)のそれぞれを個別に開閉する開閉電磁弁31,32によって形成されている。流路選択手段30(開閉電磁弁31,32)は後述する演算処理部40からの制御信号によって開閉制御(流路選択制御)されるものであっても、手動或いは人的なスイッチング操作によって開閉動作(流路選択動作)するものであってもよい。 The channel selection means 30 selectively communicates the sample water supply channel 20 with the inflow channels 13 (13 1 ) and 13 (13 2 ) in the plurality of detection units 10 and 10. Here, the selective communication means that when the sample water supply channel 20 (21, 22, 23) communicates with one inflow channel 13 (13 1 ), the other inflow channel 13 ( 13 2 ) means not communicating. In the illustrated example, the flow path selecting means 30 is provided for the inflow flow paths 13 (13 1 ) and 13 (13 2 ), and each of the inflow flow paths 13 (13 1 ) and 13 (13 2 ) is provided. It is formed by open / close solenoid valves 31 and 32 that open and close individually. Even if the flow path selection means 30 (open / close electromagnetic valves 31 and 32) is controlled to open and close (flow path selection control) by a control signal from the arithmetic processing unit 40 described later, the flow path selection means 30 (open / close electromagnetic valves 31 and 32) can be opened or closed manually or manually. It may operate (channel selection operation).

演算処理部40は、検出部12の検出信号を演算処理するものである。図示の例では検出ユニット10,10毎に対応してそれぞれ演算処理部40を設けているが、これに限らず、一つ又は複数個の演算処理部40で並列的に複数の検出ユニット10からの検出信号を処理するものであってもよい。図示の例では、各検出ユニット10,10に対応した演算処理部40がその周辺要素と共に演算処理ユニット40Uを形成している。演算処理部40の周辺要素としては、キーボード等の入力装置41、ディスプレイ等の出力装置42、メモリカード等の記憶装置43、増幅器44等が含まれる。   The arithmetic processing unit 40 performs arithmetic processing on the detection signal of the detection unit 12. In the illustrated example, the arithmetic processing units 40 are provided corresponding to the detection units 10, 10. However, the present invention is not limited to this, and one or a plurality of arithmetic processing units 40 can be connected in parallel from a plurality of detection units 10. The detection signal may be processed. In the illustrated example, the arithmetic processing unit 40 corresponding to each of the detection units 10 and 10 forms an arithmetic processing unit 40U together with its peripheral elements. Peripheral elements of the arithmetic processing unit 40 include an input device 41 such as a keyboard, an output device 42 such as a display, a storage device 43 such as a memory card, an amplifier 44, and the like.

このような基本構成を備えた水質連続計測装置1は、演算処理部40の制御機能(制御手段)として、図2に示した各手段を備えている。その一つは、異常検知手段40Aである。異常検知手段40Aは、検出部12の検出信号や演算処理部40の制御信号に基づいて装置の異常を検知するものである。装置の異常とは、検出ユニット10の動作不良に基づく異常や検出ユニット10の経時的に蓄積される汚れに基づく異常、演算処理ユニット40Uの動作異常等、検出ユニット10又は演算処理ユニット40Uの交換を必要とする異常を指しており、試料水の水質悪化による検出値の変動は含まない。また、異常検知手段40Aは、前述した装置の異常が検知されたことを音,表示,発信等によって報知する手段を合わせて持つことができる。   The water quality continuous measurement apparatus 1 having such a basic configuration includes each unit shown in FIG. 2 as a control function (control unit) of the arithmetic processing unit 40. One of them is the abnormality detection means 40A. The abnormality detection unit 40A detects an abnormality of the apparatus based on the detection signal of the detection unit 12 and the control signal of the arithmetic processing unit 40. The abnormality of the apparatus refers to an abnormality based on an operation failure of the detection unit 10, an abnormality based on dirt accumulated over time of the detection unit 10, an operation abnormality of the arithmetic processing unit 40U, etc. Replacement of the detection unit 10 or the arithmetic processing unit 40U This does not include fluctuations in the detected value due to deterioration of the water quality of the sample water. Further, the abnormality detection means 40A can have a means for notifying that the above-described apparatus abnormality is detected by sound, display, transmission, or the like.

演算処理部40が備えるもう一つの手段は、流路選択制御手段40Bである。流路選択制御手段40Bは、前述した流路選択手段30を制御して検出ユニット10の切り替えを行う手段である。具体的には、異常検知手段40Aが異常を検知した際に又は切り替え操作信号が入力された際に流路選択手段30を制御し、検出信号を出力している検出ユニット10の流入流路13(131)を試料水供給流路20から遮断し、他の検出ユニット10の流入流路13(132)を試料水供給流路20と連通させるものである。更に具体的には、現在試料水が流れている一方の流入流路131に装備された開閉電磁弁31を閉止して、他の検出ユニット10における流入流路132に装備された開閉電磁弁32を開放させることで、他の検出ユニット10側に試料水を流入させるものである。 Another means included in the arithmetic processing unit 40 is a flow path selection control means 40B. The channel selection control means 40B is a means for switching the detection unit 10 by controlling the channel selection means 30 described above. Specifically, when the abnormality detection means 40A detects an abnormality or when a switching operation signal is input, the flow path selection means 30 is controlled and the inflow flow path 13 of the detection unit 10 outputting the detection signal. (13 1 ) is blocked from the sample water supply channel 20, and the inflow channel 13 (13 2 ) of the other detection unit 10 is communicated with the sample water supply channel 20. More specifically, the closed-off solenoid valve 31 that is provided current to one of the inlet channel 13 1 sample water is flowing, closing electromagnetic that is provided on the inflow passage 13 2 in the other detection unit 10 By opening the valve 32, the sample water flows into the other detection unit 10 side.

また、演算処理部40は、検出部12(受光部12B)の検出信号に基づいて水質評価指標の計測値を出力する本来の機能(水質評価指標出力手段40C)を備えている。これは、例えば、水質評価指標として試料水の濁度と色度の一方又は両方を求める場合には、光源部12Aからフローセル11内に投光された光のうちフローセル11を透過した光を受光部12Bによって検出し、その検出信号から透過光量を求め、この透過光量と予め設定された検量線から試料水の濁度又は色度を算出する。   The arithmetic processing unit 40 has an original function (water quality evaluation index output means 40C) that outputs a measurement value of the water quality evaluation index based on the detection signal of the detection unit 12 (light receiving unit 12B). For example, when one or both of turbidity and chromaticity of sample water is obtained as a water quality evaluation index, light transmitted through the flow cell 11 is received from the light projected from the light source unit 12A into the flow cell 11. Detected by the unit 12B, the transmitted light amount is obtained from the detection signal, and the turbidity or chromaticity of the sample water is calculated from the transmitted light amount and a preset calibration curve.

このような特徴を有する水質連続計測装置1は、複数の検出ユニット10,10,…のうちの一つを使用して、試料水供給流路20と流入流路13とを連通させることで、流入流路13を介して試料水がフローセル11内に流入し、フローセル11に流入した試料水は排水流路14から排水される。フローセル11に流入した試料水は検出部12によって検出され、検出部12は濁度・色度等の水質評価指標に係る検出信号を出力する。これに対して演算処理部40は出力された検出信号を演算処理して、求めようとする水質評価指標に係る計測値を出力する。フローセル11への試料水の流入は連続的に行われ、検出部12の検出動作は設定されたサンプリング間隔で行われる。これによって実質的に24時間連続での試料水の水質監視が可能になる。   The water quality continuous measuring apparatus 1 having such a feature uses one of the plurality of detection units 10, 10,... To communicate the sample water supply channel 20 and the inflow channel 13 with each other. Sample water flows into the flow cell 11 via the inflow channel 13, and the sample water that flows into the flow cell 11 is drained from the drain channel 14. The sample water flowing into the flow cell 11 is detected by the detection unit 12, and the detection unit 12 outputs a detection signal related to a water quality evaluation index such as turbidity and chromaticity. On the other hand, the arithmetic processing unit 40 performs arithmetic processing on the output detection signal and outputs a measurement value related to the water quality evaluation index to be obtained. The flow of sample water into the flow cell 11 is continuously performed, and the detection operation of the detection unit 12 is performed at a set sampling interval. This makes it possible to monitor the water quality of the sample water substantially continuously for 24 hours.

そして、使用中の検出ユニット10に何らかの不具合が発生した場合には、検出部12の検出信号が異常信号となり、演算処理ユニット40Uに不具合が発生した場合には演算処理部40の制御信号が異常信号になるので、演算処理部40の異常検知手段40Aがこのような装置の異常を検知して検知信号を出力する。この異常検知信号が出力されると、演算処理部40の流路選択制御手段40Bが機能して、流路選択手段30を切り替え動作させ、現在使用中の検出ユニット10における流入流路131を遮断状態にし、バックアップ用に備えられる別の検出ユニット10における流入流路132を連通状態にする。 When a malfunction occurs in the detection unit 10 in use, the detection signal of the detection unit 12 becomes an abnormal signal, and when a malfunction occurs in the arithmetic processing unit 40U, the control signal of the arithmetic processing unit 40 is abnormal. Since it becomes a signal, the abnormality detection means 40A of the arithmetic processing unit 40 detects such an abnormality of the device and outputs a detection signal. When the abnormality detection signal is output, the flow path selection control unit 40B of the arithmetic processing unit 40 functions to operate switch the channel selection unit 30, the inlet passage 13 1 in the detection unit 10 currently in use and a cutoff state, the inlet passage 13 2 in another detection unit 10 provided for backup in communication with.

そして、検出ユニット10毎に演算処理部40を備えるものでは、不具合を生じた検出ユニット10(101)からの検出信号を演算処理していた演算処理部40(401)は、流路選択制御手段40Bの機能を実行すると共に、記憶装置(メモリーカード)43に記憶しているこれまで処理した演算処理結果をバックアップ用の検出ユニット10(102)に対応した演算処理部40(402)に転送する。その後は、検出データ及び設定条件をこれまで演算処理していた演算処理部40(401)から引き継いで、新たな演算処理部40(402)によって検出ユニット10(102)の検出動作が実行され、その検出によって得た検出信号の演算処理を新たな演算処理部40(402)が引き続き行う。 In the case where each detection unit 10 includes the arithmetic processing unit 40, the arithmetic processing unit 40 (40 1 ) that has performed the arithmetic processing on the detection signal from the detection unit 10 (10 1 ) in which the defect has occurred is the flow path selection unit. The function of the control means 40B is executed, and the arithmetic processing result stored so far stored in the storage device (memory card) 43 is processed to the arithmetic processing unit 40 (40 2 ) corresponding to the backup detection unit 10 (10 2 ). ). After that, the detection data and the setting conditions are taken over from the arithmetic processing unit 40 (40 1 ) that has been arithmetically processed so far, and the detection operation of the detection unit 10 (10 2 ) is performed by the new arithmetic processing unit 40 (40 2 ). The new calculation processing unit 40 (40 2 ) continues the calculation process of the detection signal that is executed and obtained by the detection.

このように水質連続計測装置1は、一つの検出ユニット10(101)に不具合が発生しても、バックアップ用の検出ユニット10(102)が即座にその後の処理を引き継いで行うことができる。この場合は、一つの演算処理部40が複数の検出ユニット10(101,102)からの検出信号を演算処理するものであってもよいし、検出ユニット101,102毎に演算処理部401,402を設けるものであってもよい。複数の演算処理部401,402を備える場合には、一つの演算処理部401が処理した演算処理結果を新たな演算処理部402が引き継いでその後の処理を行う。このような水質連続計測装置1によると、水質監視の連続性が途絶えることがなく、水質連続計測装置1の維持管理に要する人的な作業を著しく減らすことができ、維持管理費用の大幅な削減が可能になる。 As described above, the water quality continuous measurement apparatus 1 can immediately perform subsequent processing by the backup detection unit 10 (10 2 ) even if a failure occurs in one detection unit 10 (10 1 ). . In this case, one arithmetic processing unit 40 may perform arithmetic processing on detection signals from the plurality of detection units 10 (10 1 , 10 2 ), or may perform arithmetic processing for each detection unit 10 1 , 10 2. The parts 40 1 and 40 2 may be provided. When a plurality of arithmetic processing units 40 1 and 40 2 are provided, a new arithmetic processing unit 40 2 takes over the arithmetic processing result processed by one arithmetic processing unit 40 1 and performs subsequent processing. According to such a water quality continuous measuring apparatus 1, the continuity of water quality monitoring is not interrupted, and the human work required for the maintenance of the water quality continuous measuring apparatus 1 can be remarkably reduced, and the maintenance cost is greatly reduced. Is possible.

また、演算処理部40における流路選択制御手段40Bの機能及び演算処理部40(401)自体を新たな演算処理部40(402)に切り替える動作を手動のスイッチ操作等で行うようにしてもよい。この場合には、検出ユニット10に不具合が生じた場合に、無人で連続計測を維持させることはできないが、スイッチ操作等の簡単な切り替え操作で引き続き正常な計測動作を継続させることができるので、専門作業員の到着を待たずしても現場の設備係員等で充分に対応することが可能になる。この際には、異常検知手段40Aは音,表示,発信等で人に異常を報知することが必要になる。 Further, the function of the flow path selection control means 40B in the arithmetic processing unit 40 and the operation of switching the arithmetic processing unit 40 (40 1 ) itself to a new arithmetic processing unit 40 (40 2 ) are performed by a manual switch operation or the like. Also good. In this case, if a failure occurs in the detection unit 10, it is not possible to maintain continuous measurement without an attendant, but normal measurement operation can be continued with a simple switching operation such as a switch operation. Even without waiting for the arrival of a specialized worker, it becomes possible for the on-site equipment staff to respond sufficiently. At this time, the abnormality detection means 40A needs to notify the person of the abnormality by sound, display, transmission, or the like.

図3は、水質連続計測装置に対する遠隔監視システムを説明する説明図である。前述したように水質連続計測装置1は、複数の検出ユニット10(101,102)と演算処理部40(401,402)を備えている。また、各検出ユニット101と演算処理部401或いは検出ユニット102と演算処理部402がそれぞれユニット化(計測ユニット)されて水質連続計測装置1に装備されている。そして、水質連続計測装置1は、演算処理部40(401,402)の演算処理結果を遠隔送信すると共に遠隔地からの制御信号を受信する送受信部50を備える。送受信部50は、既設のネットワーク回線Nに接続され、このネットワーク回線Nを介して遠隔監視部51に情報を送信することができると共に、ネットワーク回線Nを介して遠隔監視部51等から制御信号を含む情報を受信することができるものである。送受信部50は水質連続計測装置1に外付きで接続してもよいし、水質連続計測装置1に内蔵したものであってもよい。この送受信部50を備えることで、演算処理部40の異常検知手段40Aが出力した異常検知信号を遠隔監視部51で受信することができ、遠隔監視部51からの各種制御信号で演算処理部40の動作を遠隔操作することが可能になる。この遠隔監視部51は、例えば、ネットワーク回線Nに接続されたサーバーコンピュータによって構築することができる。 FIG. 3 is an explanatory diagram for explaining a remote monitoring system for the continuous water quality measuring device. As described above, the water quality continuous measurement apparatus 1 includes a plurality of detection units 10 (10 1 , 10 2 ) and an arithmetic processing unit 40 (40 1 , 40 2 ). In addition, each detection unit 10 1 and the arithmetic processing unit 40 1, or the detection unit 10 2 and the arithmetic processing unit 40 2 are unitized (measurement unit) and are equipped in the continuous water quality measurement device 1. Then, water continuous measuring apparatus 1 includes a transceiver unit 50 for receiving control signals from a remote location with the operation result of the arithmetic processing section 40 (40 1, 40 2) for remotely transmitting. The transmission / reception unit 50 is connected to an existing network line N, can transmit information to the remote monitoring unit 51 via the network line N, and receives a control signal from the remote monitoring unit 51 and the like via the network line N. It is possible to receive information including. The transmitter / receiver 50 may be externally connected to the water quality continuous measurement device 1 or may be built in the water quality continuous measurement device 1. By providing this transmission / reception unit 50, the abnormality detection signal output by the abnormality detection means 40 </ b> A of the arithmetic processing unit 40 can be received by the remote monitoring unit 51, and the arithmetic processing unit 40 can be received by various control signals from the remote monitoring unit 51. Can be remotely controlled. The remote monitoring unit 51 can be constructed by a server computer connected to the network line N, for example.

このようなシステム構成によると、演算処理部40の演算処理結果(水質評価指標の計測値、異常検知手段40Aの出力等)が随時遠隔監視部51に送信され、遠隔監視部51ではこの送信された演算処理結果をモニタ又は分析することができる。また、使用中の演算処理部40(401)が故障して演算処理結果の出力を発信しなくなった場合には、遠隔監視部51はこの状態を検知することができる。そして、このような演算処理部40(401)の故障が検知された場合には、遠隔監視部51からの制御信号による遠隔操作で新たな演算処理部40(402)への切り替えを行い、切り替えられた新たな演算処理部40(402)の流路選択制御手段40Bを機能させて、流路選択手段30の切り替えを行う。 According to such a system configuration, the calculation processing result of the calculation processing unit 40 (measured value of water quality evaluation index, output of the abnormality detection means 40A, etc.) is transmitted to the remote monitoring unit 51 as needed, and the remote monitoring unit 51 transmits this result. It is possible to monitor or analyze the result of the arithmetic processing. Further, when the arithmetic processing unit 40 (40 1 ) in use breaks down and no longer outputs the arithmetic processing result, the remote monitoring unit 51 can detect this state. When such a failure of the arithmetic processing unit 40 (40 1 ) is detected, switching to a new arithmetic processing unit 40 (40 2 ) is performed by remote operation using a control signal from the remote monitoring unit 51. The flow path selection means 30 is switched by causing the flow path selection control means 40B of the switched new arithmetic processing unit 40 (40 2 ) to function.

以下に、水質評価指標として試料水の濁度と色度を計測する水質連続計測装置を例に具体的な構造を説明する。前述の説明と共通する部位は同一符号を付して重複説明を一部省略する。図4は、本発明の実施形態に係る水質連続計測装置の装置構成例を示した説明図であり、同図(a)が内部構造を示した側面図、同図(b)が計測ユニットを示した正面図である。水質連続計測装置1は、筐体(装置本体)2内に2つの計測ユニット1A,1Bが配備されている。一つの計測ユニット1Aが稼働用であり、もう一つの計測ユニット1Bがバックアップ用である。各計測ユニット1A,1Bは前述した検出ユニット10(101,102)と演算処理ユニット40Uを備えている。筐体(装置本体)2は、演算処理ユニット40Uの表示装置(出力装置)42が視認できる窓2A,2Aを2つの側面に備えており、各々の窓2A,2Aに計測ユニット1A,1Bの演算処理ユニット40Uに備えられる表示装置が対面するようになっている。窓部2A,2Bが備えられる側面には図示省略のドア部が設けられ、ドア部を開放することで、計測ユニット1A,1Bの着脱又は操作が可能なようになっている。また、筐体2には試料水供給流路20の端部となる給水継手20Aと排水流路14の端部となる排水継手14Aが取り付けられている。 Hereinafter, a specific structure will be described by taking as an example a water quality continuous measurement device that measures turbidity and chromaticity of sample water as a water quality evaluation index. Parts common to the above description are given the same reference numerals, and a part of overlapping description is omitted. FIG. 4 is an explanatory view showing an apparatus configuration example of a continuous water quality measuring apparatus according to an embodiment of the present invention, where FIG. 4 (a) is a side view showing the internal structure, and FIG. 4 (b) is a measuring unit.
