Description

本発明は、水道水を供給する水道管路内の水質を制御する水質制御装置、水質を管理する水質管理システム、水質管理装置、及び水質管理方法に関する。   The present invention relates to a water quality control device that controls the quality of water in a water pipeline that supplies tap water, a water quality management system that manages water quality, a water quality management device, and a water quality management method.

従来、このような水質制御装置としては、水道管路網の水道水の滞留が発生する箇所にワンタッチで接続され、その箇所の水質を検査し、水質が所定の基準外である場合に捨水制御を行う可搬型捨水検査装置が開示されている（例えば、特許文献１参照）。   Conventionally, such a water quality control device is connected to a place where tap water stays in the water pipe network with a single touch, inspects the water quality at that place, and discards the water if the water quality is outside a predetermined standard. A portable wastewater inspection apparatus that performs control is disclosed (for example, see Patent Document 1).

特許第４５３７９６２号Japanese Patent No. 4537962

ここで、上記可搬型捨水検査装置と同様の機能を有する捨水検査装置を、水道管路網の複数個所に常設すると、より確実に水道管路網の水質を制御することができると考えられる。しかしながら、上記可搬型捨水検査装置では、捨水による水道管路内の水圧低下が考慮されていない。このため、水道管路網に常設された複数の捨水制御装置が同時に捨水を行うと、水道管路内の水圧が過度に低下する可能性がある。特に、水道水の消費が多いときや、震災等により水道管路内の水漏れが生じているとき等に捨水を行うと、水道管路内の水圧が過度に低下する可能性が高い。このように水道管路内の水圧が過度に低下すると、水道水を安定して供給できなくなるおそれがあると共に、水質を正確に検出できないおそれがあった。   Here, it is considered that the water quality of the water pipe network can be controlled more reliably if the water drainage inspection apparatus having the same function as the portable water discharge inspection apparatus is permanently installed in a plurality of places of the water pipe network. It is done. However, in the portable wastewater inspection apparatus, a decrease in water pressure in the water pipe due to wastewater is not considered. For this reason, if a plurality of drainage control devices permanently installed in the water pipe network simultaneously drain water, the water pressure in the water pipe may be excessively reduced. In particular, if water is drained when there is a lot of tap water consumption or when there is a water leak in the water pipeline due to an earthquake, etc., the water pressure in the water pipeline is likely to drop excessively. . As described above, when the water pressure in the water pipe line is excessively lowered, there is a possibility that the tap water cannot be stably supplied and the water quality may not be accurately detected.

まず、本発明の第１実施形態に係る水質制御装置を説明する。図１は、本発明の第１実施形態に係る水質制御装置の概略構成図、図２は、図１の水質制御装置の機能ブロック図である。   First, the water quality control apparatus according to the first embodiment of the present invention will be described. FIG. 1 is a schematic configuration diagram of a water quality control device according to the first embodiment of the present invention, and FIG. 2 is a functional block diagram of the water quality control device of FIG.

図１に示すように、水質制御装置１００は、流量計１と、水圧検出手段である水圧計２と、排水手段３と、水質検出手段４と、制御手段５と、を備えている。   As shown in FIG. 1, the water quality control device 100 includes a flow meter 1, a water pressure gauge 2 that is a water pressure detection means, a drainage means 3, a water quality detection means 4, and a control means 5.

流量計１及び水圧計２は、水道水を供給する水道管路１０から分岐した排水管１１に設けられている。流量計１は、水道管路１０内から排水管１１内に導入された水の単位時間当たりの流量を検出する。水圧計２は、排水管１１内の水圧を検出する。   The flow meter 1 and the water pressure meter 2 are provided in a drain pipe 11 branched from a water pipe 10 that supplies tap water. The flow meter 1 detects the flow rate per unit time of the water introduced from the water pipe 10 into the drain pipe 11. The water pressure gauge 2 detects the water pressure in the drain pipe 11.

排水手段３は、排水管１１に設けられた電動弁６を有し、この電動弁６を開くことにより、水道管路１０内から排水管１１内に導入された水を排出し、電動弁６を閉じることにより排水を停止する。電動弁６を通過した水は、排水管１１から、例えば、排水枡、側溝、緑地等に排出される。なお、電動弁６は、電磁弁、エアー弁、油圧弁等の他の自動弁に置き換えることができる。   The drainage means 3 has a motorized valve 6 provided in the drainage pipe 11, and by opening the motorized valve 6, the water introduced into the drainage pipe 11 from the water pipe 10 is discharged, and the motorized valve 6 Stop draining by closing. The water that has passed through the motor-operated valve 6 is discharged from the drain pipe 11 to, for example, a drainage tub, a gutter, and a green space. The electric valve 6 can be replaced with other automatic valves such as a solenoid valve, an air valve, and a hydraulic valve.

水質管理手段４は、水道管路１０内から排水管１１内に導入された水の水質を検出するためのものであり、残留塩素計７、水温計８、及び導電率計９を有している。これらの残留塩素計７、水温計８、及び導電率計９は、流量計１と水圧計２との間で排水管１１から分岐したサンプリング管１２に設けられている。   The water quality management means 4 is for detecting the water quality of water introduced from the water pipe 10 into the drain pipe 11 and has a residual chlorine meter 7, a water temperature meter 8, and a conductivity meter 9. Yes. The residual chlorine meter 7, the water temperature meter 8, and the conductivity meter 9 are provided in a sampling pipe 12 branched from the drain pipe 11 between the flow meter 1 and the water pressure gauge 2.

残留塩素計７は、水道管路１０からサンプリング管１２に導入された水の残留塩素濃度を検出する。このように残留塩素濃度を検出することにより、例えば、残留塩素濃度が低下した際に、塩素の消毒効果が薄れて水質が低下したと判断することができる。   The residual chlorine meter 7 detects the residual chlorine concentration of the water introduced from the water pipe 10 into the sampling pipe 12. By detecting the residual chlorine concentration in this way, for example, when the residual chlorine concentration is reduced, it can be determined that the chlorine disinfection effect has diminished and the water quality has decreased.

水温計８は、水道管路１０からサンプリング管１２に導入された水の水温を検出する。このように水温を検出することにより、例えば、水温が上昇した際に、微生物等が繁殖しやすくなって水質が低下したと判断することができる。   The water temperature gauge 8 detects the temperature of the water introduced from the water pipe 10 into the sampling pipe 12. By detecting the water temperature in this way, for example, when the water temperature rises, it can be determined that the water quality has deteriorated because microorganisms and the like are easily propagated.

導電率計９は、水道管路１０からサンプリング管１２に導入された水の導電率を検出する。このように導電率を検出することにより、例えば、導電率が上昇した際に、電解性の不純物が増加して水質が低下したと判断することができる。   The conductivity meter 9 detects the conductivity of water introduced from the water pipe 10 into the sampling pipe 12. By detecting the conductivity in this manner, for example, when the conductivity is increased, it can be determined that the electrolytic impurities are increased and the water quality is decreased.

図１及び図２に示すように、制御手段５は、流量計１、水圧計２、残留塩素計７、水温計８、及び導電率計９に入力可能に接続されると共に、排水手段３に出力可能に接続され、後述の手順により排水手段３を制御する。また、制御手段５は、流量、水圧、残留塩素濃度、水温、導電率等の数値に異常がある場合や、排水手段３の動作に異常がある場合等に、異常通報手段１３によって異常を通報する。なお、制御手段５は、例えば、ＰＬＣ（Programmable Logic Controller）等の制御装置である。異常通報手段１３は、例えば、携帯電話通信を利用し、水質制御装置１００の管理者等の携帯電話に異常を通報する通信端末である。   As shown in FIGS. 1 and 2, the control means 5 is connected to the flow meter 1, the water pressure meter 2, the residual chlorine meter 7, the water temperature meter 8, and the conductivity meter 9 so as to be inputable, and to the drainage means 3. The drainage means 3 is controlled by a procedure described later. Further, the control means 5 reports the abnormality by the abnormality reporting means 13 when there is an abnormality in numerical values such as flow rate, water pressure, residual chlorine concentration, water temperature, conductivity, or when the operation of the drainage means 3 is abnormal. To do. The control means 5 is a control device such as a PLC (Programmable Logic Controller). The abnormality reporting means 13 is a communication terminal that reports a malfunction to a mobile phone such as an administrator of the water quality control device 100 using, for example, mobile phone communication.

ここで、制御手段５による排水手段３の制御手順を説明する。図３は、図１の水質制御装置の制御手順を示すフローチャートである。   Here, the control procedure of the drainage means 3 by the control means 5 will be described. FIG. 3 is a flowchart showing a control procedure of the water quality control apparatus of FIG.

図３に示すように、制御手段５は、まず、残留塩素計７により検出された残留塩素濃度が下限値以下であるかを判断する（ステップＳ１）。残留塩素濃度が下限値以下である場合には、水道管路１０内の水質が悪化したものと判断し、後述の残留塩素濃度調整制御を行い（ステップＳ２）、制御を終了する。   As shown in FIG. 3, the control means 5 first determines whether or not the residual chlorine concentration detected by the residual chlorine meter 7 is equal to or lower than the lower limit value (step S1). If the residual chlorine concentration is equal to or lower than the lower limit value, it is determined that the water quality in the water pipe 10 has deteriorated, residual chlorine concentration adjustment control described later is performed (step S2), and the control is terminated.

一方、残留塩素濃度が下限値よりも大きい場合には、水温計８により検出された水温が上限値以上であるかを判断する（ステップＳ３）。水温が上限値以上である場合には、水道管路１０内の水質が悪化したものと判断し、後述の水温調整制御を行い（ステップＳ４）、制御を終了する。   On the other hand, if the residual chlorine concentration is higher than the lower limit value, it is determined whether the water temperature detected by the water temperature gauge 8 is equal to or higher than the upper limit value (step S3). When the water temperature is equal to or higher than the upper limit value, it is determined that the water quality in the water pipe 10 has deteriorated, water temperature adjustment control described later is performed (step S4), and the control is terminated.

一方、水温が上限値よりも小さい場合には、導電率計９により検出された導電率が上限値以上であるかを判断する（ステップＳ５）。導電率が上限値以上である場合には、水道管路１０内の水質が悪化したものと判断し、後述の導電率調整制御を行い（ステップＳ６）、処理を終了する。一方、導電率が上限値よりも小さい場合には、そのまま制御を終了する。   On the other hand, if the water temperature is lower than the upper limit value, it is determined whether the conductivity detected by the conductivity meter 9 is equal to or higher than the upper limit value (step S5). If the conductivity is equal to or greater than the upper limit value, it is determined that the water quality in the water pipe 10 has deteriorated, conductivity adjustment control described later is performed (step S6), and the process is terminated.

In the residual chlorine concentration adjustment control, when the residual chlorine concentration becomes equal to or lower than the lower limit value, the motor-operated valve 6 of the drainage means 3 is opened and drainage is started (step S21). The opening amount of the electric valve 6 at this time is adjusted so that the flow rate per unit time detected by the flow meter 1 becomes a predetermined amount. And if drainage is started, it will be judged whether the water pressure detected with the water pressure gauge 2 is larger than a lower limit (step S22). If the water pressure is greater than the lower limit value, it is determined whether the residual chlorine concentration is greater than the reference value (step S23). If the residual chlorine concentration is greater than the reference value, the water quality in the water pipe 10 is Judged as improved. Then, the drainage is stopped (step S24), and the control is terminated. On the other hand, when the residual chlorine concentration is equal to or lower than the reference value, the drainage is continued and the process returns to step S22. In step S22, when the water pressure is equal to or lower than the lower limit value, the drainage is stopped (step S24), and the control is terminated. The reference value of the residual chlorine concentration is a value obtained by adding a predetermined margin to the lower limit value of the residual chlorine concentration, and is set to 0.4 mg / L here. In addition, the lower limit value of the water pressure is set to a value equal to or higher than the minimum water pressure required to stably supply tap water.

If the water pressure is greater than the lower limit value, it is determined whether the water temperature is lower than the reference value (step S43). If the water temperature is lower than the reference value, the water quality in the water pipe 10 is improved. to decide. And drainage is stopped (step S44) and control is ended. On the other hand, when the water temperature is equal to or higher than the reference value, drainage is continued, and the process returns to step S42. In step S42, when the water pressure is equal to or lower than the lower limit value, the drainage is stopped (step S44), and the control is terminated.

図６は、図３中の導電率調整制御を示すフローチャートである。導電率調整制御では、導電率が上限値以上となったのに応じ、残留塩素濃度調整制御のステップＳ２１と同様に排水を開始する（ステップＳ６１）。排水を開始すると、水圧計２により検出された水圧が下限値よりも大きいかを判断する（ステップＳ６２）。水圧が下限値よりも大きい場合には、導電率が基準値よりも小さいかを判断し（ステップＳ６３）、導電率が基準値よりも小さい場合には、水道管路１０内の水質が改善したものと判断する。そして、排水を停止し（ステップＳ６４）、制御を終了する。一方、導電率が基準値以上である場合には、排水を継続し、ステップＳ６２に戻る。ステップＳ６２において、水圧が下限値以下である場合には、排水を停止し（ステップＳ６４）、制御を終了する。なお、導電率の基準値は、導電率の上記上限値から所定の余裕量を減算した値であり、ここでは３４ｍＳ／ｍに設定されている。   FIG. 6 is a flowchart showing the conductivity adjustment control in FIG. In the conductivity adjustment control, drainage is started in the same manner as in step S21 of the residual chlorine concentration adjustment control when the conductivity becomes equal to or higher than the upper limit value (step S61). When drainage is started, it is determined whether or not the water pressure detected by the water pressure gauge 2 is larger than the lower limit value (step S62). If the water pressure is larger than the lower limit value, it is determined whether the conductivity is smaller than the reference value (step S63). If the conductivity is smaller than the reference value, the water quality in the water pipe 10 is improved. Judge that. And drainage is stopped (step S64) and control is ended. On the other hand, if the conductivity is equal to or higher than the reference value, the drainage is continued and the process returns to step S62. In step S62, when the water pressure is equal to or lower than the lower limit value, the drainage is stopped (step S64), and the control is terminated. The reference value of conductivity is a value obtained by subtracting a predetermined margin from the upper limit value of conductivity, and is set to 34 mS / m here.

ここで、図４〜図６の制御手順において、水圧の下限値は、水道水を安定供給するために必要とされる水圧以上に設定されている。また、水圧の下限値は、残留塩素濃度の検出に必要とされる水量を残留塩素計７に供給可能な水圧以上に設定されている。   Here, in the control procedure of FIGS. 4 to 6, the lower limit value of the water pressure is set to be equal to or higher than the water pressure required for stably supplying tap water. The lower limit value of the water pressure is set to be equal to or higher than the water pressure at which the amount of water required for detecting the residual chlorine concentration can be supplied to the residual chlorine meter 7.

以上のように構成された水質制御装置１００によれば、残留塩素計７、水温計８、及び導電率計９を有する水質検出手段４により水道管路１０内の水質に関する情報が検出され、この検出された情報に基づき水道管路１０内の水質が悪化したと判断されると、制御手段５によって排水手段３が制御され、当該排水手段３による排水が開始される。即ち、排水手段３による排水量が増やされる。これにより、水質の悪化した水道管路１０内の水が、排水管１１を通して排出され、水道管路１０内の水質が改善される。   According to the water quality control apparatus 100 configured as described above, information on the water quality in the water pipe 10 is detected by the water quality detection means 4 having the residual chlorine meter 7, the water temperature meter 8, and the conductivity meter 9. When it is determined that the water quality in the water pipe 10 has deteriorated based on the detected information, the drainage means 3 is controlled by the control means 5 and drainage by the drainage means 3 is started. That is, the amount of drainage by the drainage means 3 is increased. Thereby, the water in the water pipe 10 with deteriorated water quality is discharged through the drain pipe 11, and the water quality in the water pipe 10 is improved.

また、水質検出手段４により検出された情報に基づき水道管路１０内の水質が改善したと判断されると、制御手段５によって排水手段３が制御され、当該排水手段３による排水が停止される。即ち、排水手段３による排水量が減らされる。このため、排水が水質悪化時のみに限られ、無駄な排水が削減される。このように無駄な排水が削減されることで、浄水場などにおける薬品やエネルギー等の資源の消費が削減される。   Further, when it is determined that the water quality in the water pipe 10 has improved based on the information detected by the water quality detection means 4, the drainage means 3 is controlled by the control means 5 and the drainage by the drainage means 3 is stopped. . That is, the amount of drainage by the drainage means 3 is reduced. For this reason, wastewater is limited only when water quality deteriorates, and wasteful wastewater is reduced. By reducing wasteful wastewater in this way, consumption of resources such as chemicals and energy in water purification plants and the like is reduced.

また、水圧計２により、水道管路１０内の水圧に関する情報が検出され、排水による水圧の低下に応じ、制御手段５によって排水手段３が制御され、当該排水手段３による排水が停止される。即ち、制御手段５により、排水手段３による排水量が減らされる。このため、水道管路内の水圧低下が軽減される。さらに、水圧の下限値は、水道水を安定供給するために必要とされる水圧以上に設定されているため、水道水を安定して供給することができる。また、水圧の下限値は、残留塩素濃度の検出に必要とされる水量を残留塩素計７に供給可能な水圧以上に設定されているため、水質検出手段４の信頼性が保たれる。   Further, the water pressure gauge 2 detects information relating to the water pressure in the water pipe 10, the drainage means 3 is controlled by the control means 5 in accordance with a decrease in the water pressure due to drainage, and drainage by the drainage means 3 is stopped. That is, the amount of drainage by the drainage means 3 is reduced by the control means 5. For this reason, the water pressure fall in a water pipe line is reduced. Furthermore, since the lower limit value of the water pressure is set to be equal to or higher than the water pressure required to stably supply tap water, tap water can be supplied stably. Further, since the lower limit value of the water pressure is set to be equal to or higher than the water pressure at which the amount of water required for detecting the residual chlorine concentration can be supplied to the residual chlorine meter 7, the reliability of the water quality detecting means 4 is maintained.

また、残留塩素計７、水温計８、及び導電率計９を有する水質検出手段４により、水道管路１０内の水質に関し複数種類の情報が検出されるため、水質が多面的に把握され、水質の悪化がより確実に把握される。特に、導電率計９が検出する導電率により、水道水中の塩素では解消されない水質悪化現象、即ち残留塩素濃度では把握されない水質悪化現象が把握される。このような水質悪化現象としては、例えば、電解性不純物の混入等が挙げられる。   In addition, since the water quality detection means 4 having the residual chlorine meter 7, the water temperature meter 8, and the conductivity meter 9 detects a plurality of types of information regarding the water quality in the water pipe 10, the water quality is grasped from various aspects. Deterioration of water quality can be grasped more reliably. In particular, the conductivity detected by the conductivity meter 9 identifies a water quality deterioration phenomenon that cannot be eliminated by chlorine in tap water, that is, a water quality deterioration phenomenon that cannot be grasped by the residual chlorine concentration. Examples of such a water quality deterioration phenomenon include mixing of electrolytic impurities.

なお、発明者等は、水質悪化を防止するために常時排水が行われていた水道管路に、水質制御装置１００を設置し、設置前の１年間と設置後の１年間とで排水量の比較を行った。この際、図３に示すステップＳ２の残留塩素濃度調整制御のみを行い、ステップＳ４の水温調整制御及びステップＳ６の導電率調整制御を行わないこととし、残留塩素濃度調整制御時の流量は１００Ｌ／分とした。その結果、設置前の１年間は６２００ｍ３であった排水量が、設置後の１年間は２８００ｍ３となり、無駄な排水が３４００ｍ３削減されたことが確認された。 In addition, the inventors installed a water quality control device 100 in a water pipe that was always drained to prevent deterioration of water quality, and compared the amount of drainage between the year before installation and the year after installation. Went. At this time, only the residual chlorine concentration adjustment control in step S2 shown in FIG. 3 is performed, the water temperature adjustment control in step S4 and the conductivity adjustment control in step S6 are not performed, and the flow rate at the time of residual chlorine concentration adjustment control is 100 L / Minutes. As a result, it was confirmed that the amount of wastewater that was 6200 m 3 in the year before installation became 2800 m 3 in the year after installation, and that wasteful waste water was reduced by 3400 m 3 .

It is a functional block diagram of the water quality management apparatus.

図７に示すように、水質管理システム２００は、水質管理装置３００と、複数の水質制御装置４００と、により構成されたシステムであってもよい。   As shown in FIG. 7, the water quality management system 200 may be a system including a water quality management device 300 and a plurality of water quality control devices 400.

図８に示すように、水質制御装置４００は、第１実施形態の水質制御装置１００に、水質管理装置３００との通信手段１４を付加したものである。この通信手段１４は、流量計１、水圧計２、及び水質検出手段４で検出された各種情報を水質管理装置３００に送信し、水質管理装置３００からの制御指令を受信する。水質制御装置４００の制御手段５は、水質制御装置１００の制御手段５と同様の制御を実施するのに加え、水質管理装置３００からの制御指令を通信手段１４が受信した場合には、当該制御指令に従った制御を実施する。   As shown in FIG. 8, the water quality control device 400 is obtained by adding a communication means 14 with the water quality management device 300 to the water quality control device 100 of the first embodiment. The communication unit 14 transmits various information detected by the flow meter 1, the water pressure meter 2, and the water quality detection unit 4 to the water quality management device 300 and receives a control command from the water quality management device 300. The control means 5 of the water quality control device 400 performs the same control as the control means 5 of the water quality control device 100, and when the communication means 14 receives a control command from the water quality management device 300, the control means 5 Perform control according to the command.

水質管理装置３００は、水質制御装置４００が設置されている場所とは異なる場所に設置された装置であり、図９に示すように、通信手段１５と、操作入力手段１６と、表示手段１７と、記録手段１８と、異常通報手段１９と、管理手段２０と、を備えている。   The water quality management device 300 is a device installed at a location different from the location where the water quality control device 400 is installed, and as shown in FIG. 9, the communication means 15, the operation input means 16, the display means 17, , Recording means 18, abnormality reporting means 19, and management means 20.

通信手段１５は、水質制御装置４００の通信手段１４から送信された各種情報を受信し、水質制御装置４００への制御指令を送信する。即ち、通信手段１５は、水質制御装置４００の水圧計２及び水質検出手段４により検出された情報を取得する情報取得手段として機能する。通信手段１４及び通信手段１５は、有線であっても無線であってもよい。また、インターネットを経由したものであってもよい。   The communication unit 15 receives various information transmitted from the communication unit 14 of the water quality control device 400 and transmits a control command to the water quality control device 400. That is, the communication unit 15 functions as an information acquisition unit that acquires information detected by the water pressure gauge 2 and the water quality detection unit 4 of the water quality control device 400. The communication unit 14 and the communication unit 15 may be wired or wireless. It may also be via the Internet.

管理手段２０は、例えば、パーソナルコンピュータ等の処理装置である。管理手段２０は、通信手段１５から取得した各種情報に基づき把握される水道管路網の水質悪化に応じ、排水を開始すべき水質制御装置４００を特定し、その水質制御装置４００に排水開始を指示する制御指令を通信手段１５に出力する。さらに、管理手段２０は、通信手段１５から取得した各種情報に基づき把握される水道管路網の水圧低下に応じ、排水を停止すべき水質制御装置４００を特定し、その水質制御装置４００に排水停止を指示する制御指令を通信手段１５に出力する。これにより、管理手段２０は、水道管路網内の水圧を所定値以上に保つ。この所定値は、水道水を安定供給するために必要とされる水圧以上の値である。更に、この所定値は、残留塩素濃度の検出に必要とされる水量を残留塩素計７に供給可能な水圧以上の値である。   The management means 20 is a processing device such as a personal computer, for example. The management means 20 identifies the water quality control device 400 that should start drainage according to the deterioration of the water quality of the water pipe network that is grasped based on various information acquired from the communication means 15, and starts the drainage to the water quality control device 400. The instructed control command is output to the communication means 15. Furthermore, the management means 20 identifies the water quality control device 400 that should stop drainage in response to a drop in the water pressure in the water pipe network grasped based on various information acquired from the communication means 15, and drains the water quality control device 400 to the water quality control device 400. A control command for instructing the stop is output to the communication means 15. Thereby, the management means 20 keeps the water pressure in a water pipe network more than predetermined value. This predetermined value is a value equal to or higher than the water pressure required for stably supplying tap water. Further, this predetermined value is a value equal to or higher than the water pressure at which the amount of water required for detecting the residual chlorine concentration can be supplied to the residual chlorine meter 7.

また、管理手段２０は、通信手段１５から取得した各種情報を表示手段１７に表示し、記録手段１８に記録し、各種情報に異常がある場合には異常通報手段１９によって異常を通報する。表示手段１７は、例えば、液晶パネル等のモニターであり、記録手段１８は、例えば、ハードディスク等の記憶装置であり、異常通報手段１９は、例えば、異常通報手段１３と同様の通信端末である。このように管理手段２０は、水質制御装置４００の水質検出手段４により検出された情報を当該水質検出手段４が設置されている場所とは異なる場所で取得して出力する出力装置を構成している。   The management unit 20 displays various information acquired from the communication unit 15 on the display unit 17, records the information on the recording unit 18, and reports an abnormality by the abnormality notification unit 19 when the various information is abnormal. The display means 17 is a monitor such as a liquid crystal panel, the recording means 18 is a storage device such as a hard disk, and the abnormality notification means 19 is a communication terminal similar to the abnormality notification means 13, for example. In this way, the management unit 20 configures an output device that acquires and outputs the information detected by the water quality detection unit 4 of the water quality control device 400 at a location different from the location where the water quality detection unit 4 is installed. Yes.

さらに、管理手段２０は、オペレーターの制御指令を操作入力手段１６から取得して通信手段１５に出力し、当該制御指令の対象となる水質制御装置４００に送信する。オペレーターは、表示手段１７に表示された情報又は記録手段１８に記録された情報に基づいて水道管路網の水質及び水圧を把握し、それに応じた制御指令を操作入力手段１６に入力することができる。なお、操作入力手段１６は、例えば、ボタン、キーボード、マウス等の入力装置である。   Furthermore, the management means 20 acquires an operator's control command from the operation input means 16, outputs it to the communication means 15, and transmits it to the water quality control device 400 that is the target of the control command. The operator can grasp the water quality and water pressure of the water pipe network based on the information displayed on the display means 17 or the information recorded on the recording means 18 and input a control command corresponding to the water quality and water pressure to the operation input means 16. it can. The operation input means 16 is an input device such as a button, a keyboard, or a mouse.

以上のように構成された水質管理システム２００によれば、水質制御装置４００の排水制御のために検出された水質に関する情報が、水質制御装置４００の水質検出手段４が設置されている場所とは異なる場所において水質管理装置３００の管理手段２０に取得されて出力される。管理手段２０から出力された情報は、表示手段１７に表示され、記録手段１８に記録され、例えば水質変化の特性の把握等に有効活用される。   According to the water quality management system 200 configured as described above, the information on the water quality detected for the drainage control of the water quality control device 400 is the place where the water quality detection means 4 of the water quality control device 400 is installed. It is acquired and output to the management means 20 of the water quality management device 300 at different locations. The information output from the management means 20 is displayed on the display means 17 and recorded in the recording means 18 and is effectively used for grasping the characteristics of the water quality change, for example.

また、水質検出手段４により検出された水道管路内の水質に関する情報が、水質管理装置３００において取得され、その情報に基づき把握される水道管路内の水質悪化に応じ、水質管理装置３００の処理又はオペレーターの操作入力が行われ、それに従って排水手段３の排水量が増やされる。これにより、水質の悪化した水が排出され、水道管路内の水質が改善される。また、水圧計２により検出された水道管路内の水圧に関する情報が、水質管理装置３００において取得され、その情報に基づき把握される水道管路内の水圧低下に応じ、水質管理装置３００の処理又はオペレーターの操作入力が行われ、それに従って排水手段３の排水量が減らされる、又は排水が停止される。これにより、水道管路内の水圧低下が軽減される。さらに、水道管路網の水圧は、水道水を安定供給するために必要とされる水圧以上に保たれるため、水道水を安定して供給することができる。また、水道管路網の水圧は、残留塩素濃度の検出に必要とされる水量を残留塩素計７に供給可能な水圧以上に保たれるため、水質検出手段４の信頼性が保たれる。このように、水道管路において動作する水質制御装置４００とは異なる場所から水質制御装置４００を制御することにより、水道管路内の水質悪化及び水圧低下だけでなく、他の情報も考慮して複雑な制御を行うことができる。   In addition, information on the water quality in the water pipeline detected by the water quality detection means 4 is acquired in the water quality management device 300, and the water quality management device 300 determines the water quality deterioration in the water pipeline that is grasped based on the information. Processing or operator input is performed, and the amount of drainage of the drainage means 3 is increased accordingly. As a result, water with deteriorated water quality is discharged, and the water quality in the water pipe is improved. In addition, the information on the water pressure in the water pipe detected by the water pressure gauge 2 is acquired in the water quality management device 300, and the processing of the water quality management device 300 is performed according to the water pressure drop in the water pipeline that is grasped based on the information. Alternatively, an operator input is performed, and the drainage amount of the drainage means 3 is reduced or drainage is stopped accordingly. Thereby, the water pressure fall in a water pipe line is reduced. Furthermore, since the water pressure of the water pipe network is kept higher than the water pressure required to stably supply tap water, tap water can be supplied stably. Further, since the water pressure in the water pipe network is kept higher than the water pressure required to detect the residual chlorine concentration, the reliability of the water quality detecting means 4 can be maintained. In this way, by controlling the water quality control device 400 from a location different from the water quality control device 400 operating in the water pipeline, not only water quality deterioration and water pressure drop in the water pipeline, but also other information is taken into consideration. Complex control can be performed.

また、水質管理装置３００では、複数の水質制御装置４００の水質検出手段４により検出された情報が取得され、取得された情報に基づき把握される水道管路１０内の水質悪化に応じて行われる水質管理装置３００の処理又はオペレーターの操作入力に従い、複数の水質制御装置４００の排水手段３が制御される。このため、複数の水質制御装置４００の水質検出手段４により検出された情報に基づき、水道管路網全体の水質を把握し、当該水道管路網全体の水質の最適化を考慮して複数の水質制御装置４００の排水手段３を制御することが可能となる。   Moreover, in the water quality management apparatus 300, the information detected by the water quality detection means 4 of the plurality of water quality control apparatuses 400 is acquired, and is performed according to the deterioration of the water quality in the water pipe 10 that is grasped based on the acquired information. The drainage means 3 of the plurality of water quality control devices 400 are controlled in accordance with the processing of the water quality management device 300 or the operation input of the operator. For this reason, based on the information detected by the water quality detection means 4 of the plurality of water quality control devices 400, the water quality of the entire water pipeline network is grasped, and the plurality of water quality networks are optimized in consideration of optimization of the water quality of the entire water pipeline network. It becomes possible to control the drainage means 3 of the water quality control device 400.

なお、水質管理装置３００は、外部からのインターネットアクセスが可能なものであっても良い。この場合、記録手段１８に記録された水質に関する情報等をインターネット経由で提供することができる。   The water quality management device 300 may be capable of Internet access from the outside. In this case, information on the water quality recorded in the recording means 18 can be provided via the Internet.

また、第１及び第２実施形態において、水道管路１０の水質に関する情報として、残留塩素濃度、水温、及び導電率が検出されているが、これに限られない。例えば、濁度、ＰＨ、色度、臭気等、様々なものを水質に関する情報として検出し、排水手段３の制御に用いることができる。   Moreover, in 1st and 2nd embodiment, although residual chlorine concentration, water temperature, and electrical conductivity are detected as information regarding the water quality of the water pipe 10, it is not restricted to this. For example, various things such as turbidity, pH, chromaticity, and odor can be detected as information on water quality and used for controlling the drainage means 3.
