Description

含水率測定用治具、含水率測定装置及び運転支援ナビシステムMoisture content measurement jig, moisture content measurement device, and driving support navigation system
　本発明は、含水率測定用治具、含水率測定装置及び運転支援ナビシステムに関する。 The present invention relates to a moisture content measuring jig, a moisture content measuring device, and a driving support navigation system.
　現状では、脱水機で処理後の下水汚泥(以下、脱水汚泥と記載する)の処理は、現場の熟練作業者の経験と官能的な判断に基づいて実施されている。例えば、現場の熟練作業者は、凝集混和槽内のフロックの状態、脱水された汚泥の性状、制御基盤上の計器の値などを見ながら、運転条件(汚泥供給ポンプ回転数、高分子凝集剤注入量、スクリュー回転数、プレッサ圧力)を逐次修正し、脱水汚泥の含水率が所定の値になるようにプロセスを好適化している。特に、脱水汚泥の性状、すなわち含水率に関しては、脱水汚泥を、人が手袋などをして手で採取し、脱水汚泥を持った時の感触などから含水率を瞬時に判断して汚泥の脱水プロセスにフィードバックし、プロセスを好適化している。 Currently, treatment of sewage sludge (hereinafter referred to as dewatered sludge) after being treated with a dehydrator is carried out based on the experience and sensual judgment of skilled workers on site. For example, skilled workers at the site check the operating conditions (sludge supply pump rotation speed, polymer flocculant The injection amount, screw rotation speed, and presser pressure are successively adjusted to optimize the process so that the water content of dehydrated sludge reaches a predetermined value. In particular, regarding the properties of dehydrated sludge, that is, its water content, dehydrated sludge is collected by hand by a person wearing gloves, etc., and the water content is instantly determined based on the feeling when holding the dehydrated sludge. Feedback is provided to the process to optimize it.
　最近では、近赤外線などの分光的手段を用いて脱水汚泥に非接触で含水率を計測する事例が見られるようになった。例えば、特許文献１には、搬送手段上の含液固形物を採取する自動サンプリング手段と、採取した含液固形物の表面を均一状態に整備する整備手段と、表面を整備した含液固形物の含水率を非接触的に測定する水分計とを備えたことを特徴とする含水率測定装置が開示されている（特許文献１の請求項１を参照。）。 Recently, there have been cases where the moisture content of dehydrated sludge is measured without contact using spectroscopic means such as near-infrared rays. For example, Patent Document 1 describes an automatic sampling means for collecting a liquid-containing solid on a conveying means, a maintenance means for preparing the surface of the sampled liquid-containing solid to a uniform state, and a liquid-containing solid having a prepared surface. A moisture content measuring device is disclosed, which is characterized by comprising a moisture meter that non-contactly measures the moisture content of .
　具体的には、特許文献１には、自動サンプリング手段を、採取位置と整備位置と測定位置とにわたって出退するスライド式の受皿により構成し、整備手段をロボット・アームにより構成し、水分計が近赤外線式水分計である含水率測定装置が開示されている（特許文献１の図１、請求項２及び請求項３を参照。）。 Specifically, Patent Document 1 discloses that the automatic sampling means is constituted by a sliding tray that moves in and out between a sampling position, a maintenance position, and a measurement position, the maintenance means is constituted by a robot arm, and the moisture meter is A moisture content measuring device that is a near-infrared moisture meter is disclosed (see FIG. 1, claims 2, and 3 of Patent Document 1).
特開平８－２１９９８８号公報Japanese Patent Application Publication No. 8-219988
　特許文献１に開示された含水率測定装置（以下、「従来技術」と称呼される。）により脱水汚泥の含水率を測定するためには、脱水汚泥の表面から内部まで水分量が均一であることが前提である。ところが、脱水汚泥の表面は環境中(空気中)の湿度により変動しやすく、脱水汚泥の内部は湿度による影響を受けにくいため変動しにくいので、脱水汚泥の表面と内部では含水率が異なる。従って、脱水汚泥の内部の含水率が真値に近い値である。 In order to measure the water content of dehydrated sludge using the water content measuring device disclosed in Patent Document 1 (hereinafter referred to as "prior art"), the water content must be uniform from the surface to the inside of the dehydrated sludge. This is the premise. However, the surface of dehydrated sludge easily fluctuates depending on the humidity in the environment (in the air), and the interior of dehydrated sludge is less affected by humidity and therefore does not fluctuate easily, so the moisture content on the surface and inside of dehydrated sludge is different. Therefore, the moisture content inside the dehydrated sludge is close to the true value.
　また、従来技術によると、搬送手段上の採取された脱水汚泥の表面が均一状態に整備されて、その含水率が測定されるまで、脱水汚泥の含水率の測定対象となる表面が空気に触れている。脱水汚泥の含水率が表面と内部とで異なることからわかるように、脱水汚泥が空気に触れている間、脱水汚泥表面の含水率は空気中の湿度により変動しやすい。 Furthermore, according to the conventional technology, the surface of the dehydrated sludge that is to be measured for the water content of the dehydrated sludge is not exposed to air until the surface of the collected dehydrated sludge on the conveying means is prepared in a uniform state and its water content is measured. ing. As can be seen from the fact that the moisture content of the dehydrated sludge differs between the surface and the inside, the moisture content of the surface of the dehydrated sludge tends to fluctuate depending on the humidity in the air while the dehydrated sludge is in contact with the air.
　このように従来技術では、真値に近い脱水汚泥の内部の含水率を測定できないため、脱水汚泥の含水率の測定精度が低かった。 As described above, in the conventional technology, the accuracy of measuring the water content of dehydrated sludge was low because it was not possible to measure the water content inside the dehydrated sludge that was close to the true value.
　本発明は上記課題を解決するためになされた。即ち、本発明の目的の一つは、脱水汚泥の含水率の測定精度を向上できる含水率測定用治具、含水率測定装置及び運転支援ナビシステムを提供することにある。 The present invention has been made to solve the above problems. That is, one of the objects of the present invention is to provide a water content measuring jig, a water content measuring device, and a driving support navigation system that can improve the accuracy of measuring the water content of dehydrated sludge.
　上記課題を解決するために、本発明の含水率測定用治具は、脱水機で処理した汚泥を収容するための収容空間を有する採取部材を含む採取部と、前記採取部を動作させる駆動部と、計測プローブを含み、前記採取部材の前記収容空間に収容されることにより採取された前記汚泥を前記計測プローブによって計測することにより計測情報を取得する計測部と、を有し、前記駆動部によって、前記採取部を、採取対象の前記汚泥の内部に侵入させるように動作させた後、前記採取部を前記汚泥の内部から外部に抜き出すように動作させることで、前記汚泥を前記収容空間に取り入れることにより、前記採取部が前記汚泥を採取し、前記計測部によって、前記採取部によって採取された前記汚泥の前記計測情報を取得する。 In order to solve the above problems, the moisture content measuring jig of the present invention includes a collection section including a collection member having a storage space for storing sludge treated with a dehydrator, and a drive section for operating the collection section. and a measurement unit that includes a measurement probe and acquires measurement information by measuring the sludge collected by being accommodated in the storage space of the collection member with the measurement probe, and the drive unit The sludge is moved into the storage space by operating the collection unit to enter the sludge to be collected, and then operating the collection unit to extract the sludge from the inside of the sludge to the outside. By taking in the sludge, the collection section collects the sludge, and the measurement section acquires the measurement information of the sludge collected by the collection section.

　＜本発明の概要＞
　まず本発明の理解を容易にするため、本発明の概要について説明する。一般的に知られている脱水汚泥の含水率計測方法として、経験や勘がなくても含水率を得ることができる絶乾法がある。本方法は、下水試験方法や一般汚泥試験に定められており、１０５℃で恒量を得るまで脱水汚泥を乾燥した際の試料重量に対する減量の割合として水分量が規定されている。しかし、本方法は乾燥に長時間を要するため、含水率に基づく脱水プロセスに対する迅速なフィードバックができない。一方、経験や勘が無くても短時間で含水率を得る方法として、土壌や木材チップなどの水分量を計測する手段に用いられている電気抵抗式があるが、測定可能な含水率範囲が６０％程度以下と限られるため、含水率が８０％を超えることがある脱水汚泥には不適切である。また同様な手法に時間測定型マイクロ波法があるが、本方法は含水率範囲を１００％まで広げるには大型化する必要があり、コンパクトな装置開発に不向きである。 <Summary of the present invention>
First, in order to facilitate understanding of the present invention, an outline of the present invention will be explained. A commonly known method for measuring the moisture content of dehydrated sludge is the bone-dry method, which allows the moisture content to be determined without any experience or intuition. This method is specified in sewage test methods and general sludge tests, and the water content is specified as the ratio of weight loss to the sample weight when dehydrated sludge is dried at 105° C. until a constant weight is obtained. However, this method requires a long drying time and does not provide quick feedback to the dehydration process based on moisture content. On the other hand, the electrical resistance method, which is used to measure the moisture content of soil, wood chips, etc., is a method to quickly obtain the moisture content without any experience or intuition, but the measurable moisture content range is limited. Since the water content is limited to about 60% or less, it is not suitable for dehydrated sludge whose water content may exceed 80%. A similar method is the time-measuring microwave method, but this method requires upsizing in order to expand the moisture content range to 100%, and is not suitable for developing a compact device.
　そこで、本発明の含水率計測では、近赤外分光法を用いて、水の赤外線吸収を水分量に換算することで含水率を即時的に高精度に求めることができる。 Therefore, in the moisture content measurement of the present invention, the moisture content can be determined instantly and with high precision by converting the infrared absorption of water into the moisture content using near-infrared spectroscopy.
　更に、本発明では、万が一、前記分光計測により得られた含水率が、それまでに得られた値からの傾向を大きく逸脱していた場合に備え、補助の含水率センサを具備し、常に分光と同時に稼働する構成とする。 Furthermore, in the present invention, in case the moisture content obtained by the spectroscopic measurement greatly deviates from the tendency of the previously obtained values, an auxiliary moisture content sensor is provided, and the spectroscopic measurement is always carried out. The configuration is such that they operate at the same time.
　例えば、補助センサとしてカサ重量センサや、粘度センサなどを具備することができる。補助センサを具備し、常に分光と共に稼働させることで、分光から何らかの理由で適正な含水率が得られなくても、補完するデータを得ることができる。 For example, an umbrella weight sensor, a viscosity sensor, etc. can be provided as an auxiliary sensor. By providing an auxiliary sensor and always operating it together with the spectrometer, even if an appropriate water content cannot be obtained from the spectrometer for some reason, complementary data can be obtained.
　また、補助センサの値から、適正な含水率が得られなかった理由が、分光計や補助の計測手段の不具合、脱水汚泥の採取深さが不十分であったこと、及び、脱水汚泥の含水率が何らかの原因で大きく変わったことの何れであるかを判断することができる。 In addition, the reasons why the appropriate moisture content could not be obtained from the value of the auxiliary sensor were that the spectrometer and auxiliary measuring means were defective, the sampling depth of the dehydrated sludge was insufficient, and the moisture content of the dehydrated sludge It is possible to determine whether the rate has changed significantly for some reason.
　脱水汚泥の含水率は、１日の中でも時々刻々と変動するため、ある程度の時間間隔を守って、逐次採取し、計測することが望ましい。そのため現状は、現場熟練者が手作業で含水率を計測するため、現場に長時間拘束されることがある。しかし、今後、生産年齢人口の減少が見込まれるため、人手不足により現場に配属される作業者が非熟練者である可能性がある。従って、現場者業者の経験やスキルに依存しないプロセスの構築と運転効率の最大化が課題となる。 Since the water content of dehydrated sludge fluctuates from moment to moment throughout the day, it is desirable to collect and measure it at certain time intervals. For this reason, currently experienced field workers manually measure the moisture content, which may require them to be on site for long periods of time. However, as the working-age population is expected to decline in the future, there is a possibility that the workers assigned to the site will be unskilled due to a labor shortage. Therefore, the challenge is to create a process that does not depend on the experience and skills of on-site contractors and to maximize operational efficiency.
　上記した課題を解決するために、本発明では、含水率測定用治具によって脱水汚泥の採取及び分光による計測を行う構成と、計測情報（計測データ）に基づく演算処理を自動で連続して実行して含水率を得る構成と、を含む装置構成とする。さらに、前記取得した含水率に基づき、脱水汚泥の採取プロセス（採取深さ）や汚泥の脱水プロセス条件に自動又は半自動でフィードバックする運転支援ナビシステムを用いて、脱水汚泥のプロセスを好適化する。 In order to solve the above-mentioned problems, the present invention has a configuration in which dehydrated sludge is collected using a moisture content measurement jig and measured by spectroscopy, and calculation processing based on measurement information (measurement data) is automatically and continuously executed. and a configuration for obtaining the moisture content. Further, based on the obtained moisture content, the dewatered sludge process is optimized using a driving support navigation system that automatically or semi-automatically provides feedback to the dehydrated sludge collection process (sampling depth) and sludge dewatering process conditions.
　下水汚泥処理事業の事業収入減少により、現状設備の更新は大きな負担であることも課題となっているため、既存の設備に簡便に取り付けることが可能な装置構成とする。 Due to the decrease in business income from the sewage sludge treatment business, it has become an issue that updating the current equipment is a heavy burden, so the equipment will be configured so that it can be easily installed on existing equipment.
　本発明によれば、現場作業者の経験やスキルに依存すること無く、脱水汚泥の適切な採取、計測、演算まで自動で実施されることにより、簡便に脱水汚泥の含水率を取得できるようになる。また、補助の含水率計測手段を具備することで、万が一分光計測が予想から逸脱した値をとった場合にも、ある程度補完できるため、データの欠損を防ぐことができる。さらに、含水率に基づき、脱水汚泥の採取プロセス(採取深さ)や汚泥の脱水プロセス条件にほぼ全自動又は半自動でフィードバックする運転支援ナビシステムを用いて、脱水汚泥のプロセスを好適化でき、現場作業者が現場に長時間拘束されずに済むようになる。さらに、含水率測定用治具の装置構成をコンパクトにすることで、既設の汚泥処理設備に後から容易に取り付けることができる。 According to the present invention, the moisture content of dehydrated sludge can be easily obtained by automatically performing appropriate collection, measurement, and calculation of dehydrated sludge without depending on the experience and skills of field workers. Become. Furthermore, by providing an auxiliary moisture content measuring means, even if the spectroscopic measurement takes a value that deviates from the expected value, it can be compensated to some extent, thereby preventing data loss. Furthermore, the dewatered sludge process can be optimized using an operation support navigation system that provides almost fully or semi-automatically feedback to the dewatered sludge collection process (sampling depth) and sludge dewatering process conditions based on the water content. Workers no longer need to be tied up at the site for long periods of time. Furthermore, by making the device configuration of the moisture content measuring jig compact, it can be easily installed later on in existing sludge treatment equipment.

　（ii）治具による脱水汚泥の採取及び計測
　図２Ａ、図２Ｂ、図２Ｃ及び図３は、治具２による脱水汚泥１の採取及び計測を説明するための図である。図２Ａ乃至図３を用いて、脱水汚泥１の採取プロセスを以下（１）から（３）で説明し、計測プロセスを以下（４）から（６）で説明する。
（１）図２Ａに示すように、延伸されたサンプリングユニット２ａの先端を、採取対象の脱水汚泥１の内部に挿入する。
（２）図２Ｂ及び図２Ｃに示すように、サンプリングユニット２ａの先端内部に格納されていた上蓋２ｂ、底蓋２ｃ及び断面がコ字状の採取部材２ｄをそれぞれ独立した第１駆動機構乃至第３駆動機構によって動かして脱水汚泥１に挿入し、脱水汚泥１の内部を掴む。 (ii) Collection and measurement of dehydrated sludge using jig FIGS. 2A, 2B, 2C, and 3 are diagrams for explaining collection and measurement of dehydrated sludge 1 using jig 2. Using FIGS. 2A to 3, the collection process of the dehydrated sludge 1 will be explained in (1) to (3) below, and the measurement process will be explained in (4) to (6) below.
(1) As shown in FIG. 2A, the tip of the extended sampling unit 2a is inserted into the dewatered sludge 1 to be collected.
(2) As shown in FIGS. 2B and 2C, the top cover 2b, bottom cover 2c, and sampling member 2d having a U-shaped cross section, which were stored inside the tip of the sampling unit 2a, are moved by independent first drive mechanisms or first drive mechanisms. 3. It is moved by a drive mechanism, inserted into the dehydrated sludge 1, and grasps the inside of the dehydrated sludge 1.
　具体的に述べると、図３の状態ＯＰ１において、延伸及び短縮する第１駆動機構（一例としての周知のエアシリンダ）の一部である第１ピストンロッド３１の先端に採取部材２ｄが取り付けられており、第２駆動機構（一例としての周知のエアシリンダ）の一部である第２ピストンロッド３２の先端に上蓋２ｂが取り付けられており、第３駆動機構（一例としての周知のエアシリンダ）の一部である第３ピストンロッド３３の先端に底蓋２ｃが取り付けられている。 Specifically, in state OP1 of FIG. 3, the collection member 2d is attached to the tip of the first piston rod 31 that is part of the first drive mechanism (a well-known air cylinder as an example) that extends and shortens. The upper cover 2b is attached to the tip of the second piston rod 32, which is a part of the second drive mechanism (a well-known air cylinder as an example), and the upper cover 2b is attached to the tip of the second piston rod 32, which is a part of the second drive mechanism (a well-known air cylinder as an example). A bottom cover 2c is attached to the tip of a portion of the third piston rod 33.
　状態ＯＰ１において、第１ピストンロッド３１が前方向に延びることにより、採取部材２ｄは、治具２の前方にある脱水汚泥１に向かって移動し、状態ＯＰ２に示すように、脱水汚泥１の内部に挿入される。 In state OP1, as the first piston rod 31 extends forward, the collection member 2d moves toward the dehydrated sludge 1 located in front of the jig 2, and as shown in state OP2, the inside of the dehydrated sludge 1 is removed. inserted into.
　状態ＯＰ２において、第２ピストンロッド３２が前方向に伸びることにより、上蓋２ｂは、上蓋２ｂが採取部材２ｄの上側の開口を覆う状態になるまで、前方向に移動し、第３ピストンロッド３３が前方向に伸びることにより、底蓋２ｃは、底蓋２ｃが採取部材２ｄの下側の開口を覆う状態（状態ＯＰ３）になるまで、前方向に移動する。
（３）脱水汚泥１からサンプリングユニット２ａを引き抜く。 In state OP2, as the second piston rod 32 extends forward, the upper lid 2b moves forward until the upper lid 2b covers the upper opening of the collection member 2d, and the third piston rod 33 moves forward. By extending forward, the bottom cover 2c moves forward until the bottom cover 2c covers the lower opening of the collection member 2d (state OP3).
(3) Pull out the sampling unit 2a from the dehydrated sludge 1.
　具体的に述べると、状態ＯＰ３において、第１ピストンロッド３１、第２ピストンロッド３２及び第３ピストンロッド３３が同時に後方向に縮むことにより、採取部材２ｄ、上蓋２ｂ及び底蓋２ｃは、後方向に移動する。これにより、状態ＯＰ４に示すように、採取部材２ｄは、上蓋２ｂ及び底蓋２ｃによって挟まれた状態の脱水汚泥１を、採取部材２ｄの第１の面、第２の面及び第３の面に囲まれる収容空間ＳＰ１に取り入れた状態で、脱水汚泥１から抜去される。これにより、採取部材２ｄ（採取部１１）が、脱水汚泥１の内部の脱水汚泥１を採取する。 Specifically, in state OP3, the first piston rod 31, the second piston rod 32, and the third piston rod 33 simultaneously contract in the rear direction, so that the collection member 2d, the top lid 2b, and the bottom lid 2c are moved in the rear direction. Move to. As a result, as shown in state OP4, the collection member 2d collects the dehydrated sludge 1 sandwiched between the top lid 2b and the bottom lid 2c on the first surface, second surface, and third surface of the collection member 2d. The dehydrated sludge is removed from the dehydrated sludge 1 while being taken into the storage space SP1 surrounded by. Thereby, the collecting member 2d (collecting section 11) collects the dehydrated sludge 1 inside the dehydrated sludge 1.
　この状態ＯＰ４は、採取部材２ｄの第１の面、第２の面及び第３の面に囲まれる収容空間ＳＰ１に脱水汚泥１が取り入れられ、且つ、収容空間ＳＰ１の上側が上蓋２ｂに覆われ、且つ、収容空間ＳＰ１の下側が底蓋２ｃに覆われた状態になっている。これにより、脱水汚泥１がなるべく空気に触れない状態になっている。なお、底蓋２ｃは、先端になるほど上蓋２ｂに近づくように傾斜がついている（即ち、前方に向かって上方に傾斜している。）。これは、採取部材２ｄ、上蓋２ｂ及び底蓋２ｃが、脱水汚泥１を掴んで採取しやすいようにするためである。
（４）状態ＯＰ４にて、第２ピストンロッド３２が後方向に縮むことにより、上蓋２ｂを採取した脱水汚泥１に対して後方にスライドして（ずらして）採取した脱水汚泥１の上面を外部に露出させ、次の計測にそのまま移行する。露出直前まで上蓋２ｂに押し付けられていた脱水汚泥１の上面は、平坦化され、分光計測に適した表面となっている。平坦化の方法としては、他に採取部１１の上蓋２ｂと底蓋２ｃとの間の高さをやや大きくしておき、脱水汚泥１を採取後、底蓋２ｃを第３駆動機構により押し上げて脱水汚泥１を上蓋２ｂと底蓋２ｃで挟み込んで平坦化しても良い。なお、状態ＯＰ４にて、第１ピストンロッド３１が後方向に縮むことにより、採取部材２ｄを採取した脱水汚泥１に対して後方に移動させてもよい。 In this state OP4, the dehydrated sludge 1 is taken into the storage space SP1 surrounded by the first surface, second surface, and third surface of the collection member 2d, and the upper side of the storage space SP1 is covered with the upper lid 2b. , and the lower side of the housing space SP1 is covered with the bottom lid 2c. Thereby, the dehydrated sludge 1 is kept in a state where it does not come into contact with air as much as possible. Note that the bottom cover 2c is sloped so that the tip approaches the top cover 2b (that is, it slopes upward toward the front). This is so that the collecting member 2d, the top lid 2b, and the bottom lid 2c can easily grip and collect the dehydrated sludge 1.
(4) In state OP4, the second piston rod 32 contracts in the rearward direction, so that the upper lid 2b is slid (shifted) backward relative to the collected dehydrated sludge 1, and the upper surface of the collected dehydrated sludge 1 is exposed to the outside. and then move on to the next measurement. The upper surface of the dehydrated sludge 1, which had been pressed against the upper lid 2b until just before exposure, is flattened and has a surface suitable for spectroscopic measurement. Another method for flattening is to slightly increase the height between the top lid 2b and bottom lid 2c of the collection section 11, and after collecting the dehydrated sludge 1, push up the bottom lid 2c using a third drive mechanism. The dehydrated sludge 1 may be flattened by being sandwiched between the top lid 2b and the bottom lid 2c. In addition, in state OP4, the first piston rod 31 may be contracted in the rearward direction, thereby moving the collecting member 2d backward with respect to the collected dehydrated sludge 1.
　ここで、上蓋２ｂの計測プローブ側に面した側の面に近赤外光の反射塗料を塗布しても良い。塗布することで、近赤外のベースライン測定がその場で簡便にしかも随時実施することができる。また、上蓋２ｂ全体をスライドさせなくても良く、後述の近赤外分光プローブ３ａからの照射部位のみ計測直前にカメラの絞りのようにして開放する構造にしても良い。または、後述の近赤外分光プローブ３ａからの照射部位のみ計測直前に上蓋２ｂの中に収納される構造でも良い。この他、上蓋２ｂを、近赤外を透過する材料（例えば石英など）で作成すれば、後方にスライドする必要がなくなるため、上蓋２ｂの出し入れの動作が無くなり、プロセスが容易となる。 Here, near-infrared light reflective paint may be applied to the surface of the upper lid 2b facing the measurement probe side. By applying it, near-infrared baseline measurements can be easily performed on the spot and at any time. Further, it is not necessary to slide the entire upper lid 2b, and a structure may be adopted in which only the area irradiated by the near-infrared spectroscopic probe 3a, which will be described later, is opened like the aperture of a camera just before measurement. Alternatively, a structure may be adopted in which only the region irradiated by a near-infrared spectroscopic probe 3a, which will be described later, is housed in the upper lid 2b immediately before measurement. In addition, if the upper lid 2b is made of a material that transmits near infrared rays (for example, quartz, etc.), there is no need to slide the upper lid 2b backwards, so there is no need to move the upper lid 2b in and out, and the process becomes easier.
(５)上記（４）で露出された、平坦化された脱水汚泥１の上面に、サンプリングユニット２ａの上部に挿入している近赤外分光プローブ３ａから光を照射し、反射光を近赤外分光プローブ３ａで受光し、計測情報Ｆ１を得る（近赤外分光プローブ３ａから計測情報Ｆ１を、近赤外分光器３を介して得る。）。このとき、用いる近赤外分光プローブ３ａは、照射プローブと受光プローブを一本のバンドルファイバに実装した照射・受光一体型プローブであってもよいし、照射と受光が異なる独立したプローブであってもよい。 (5) The top surface of the flattened dehydrated sludge 1 exposed in (4) above is irradiated with light from the near-infrared spectroscopic probe 3a inserted in the upper part of the sampling unit 2a, and the reflected light is The light is received by the external spectroscopy probe 3a to obtain measurement information F1 (measurement information F1 is obtained from the near-infrared spectroscopy probe 3a via the near-infrared spectrometer 3). At this time, the near-infrared spectroscopic probe 3a used may be an integrated irradiation/light-receiving probe in which an irradiation probe and a light-receiving probe are mounted on a single bundle fiber, or an independent probe with different irradiation and light-receiving functions. Good too.
　また、近赤外分光プローブ３ａがサンプリングユニット２ａの上部に固定されているので、照射部及び受光部と、脱水汚泥１の平坦化された上面との間が常に一定の距離を保つことができる。これにより、高精度の分光計測が実現できる。このとき、サンプリングユニット２ａの上部に固定されている近赤外分光プローブ３ａの照射部及び受光部と脱水汚泥１の平坦化された上面との間には、隙間がある（即ち、常に一定の厚みの空気の層がある）。なお、この隙間に同じ厚みの石英など近赤外を透過する材料が配設されてもよい（即ち、空気の層の代わりに、同じ厚みの石英など近赤外を透過する材料を用いても良い。）。 Furthermore, since the near-infrared spectroscopic probe 3a is fixed to the upper part of the sampling unit 2a, a constant distance can always be maintained between the irradiating part and the light receiving part and the flattened upper surface of the dehydrated sludge 1. . This makes it possible to achieve highly accurate spectroscopic measurements. At this time, there is a gap between the irradiating part and the light receiving part of the near-infrared spectroscopic probe 3a fixed on the top of the sampling unit 2a and the flattened top surface of the dehydrated sludge 1 (that is, there is always a constant gap (There is a thick layer of air). Note that a material that transmits near-infrared light such as quartz having the same thickness may be placed in this gap (in other words, a material that transmits near-infrared light such as quartz having the same thickness may be used instead of the air layer). good.).
　上記では、採取対象の脱水汚泥１の内部の脱水汚泥１が採取され、測定されるので、脱水汚泥１の含水率の測定精度を向上できる。更に、上記では、治具２の採取機構（採取部１１）と計測機構（計測部１２）とが一体型となっているので、採取から計測まで短時間で済む上、脱水汚泥１がなるべく空気に触れない構造となっている。これにより、含水率の変動を抑制でき、高精度に含水率を得ることができる。また、サンプリングユニット２ａに光遮断する囲い（即ち、採取部１１及び計測部１２を遮光する遮光部）が設けられても良い。これにより、汚泥脱水の採取位置が光を遮断でき無い場所であっても、分光計測が可能となる。
（６）近赤外分光プローブ３ａと同時に補助計測用プローブ３ｂからも計測情報Ｆ１を得る（補助計測用プローブ３ｂから計測情報Ｆ１を、補助計測器３’を介して得る。）。補助計測器３’の例として、カサ重量や粘度を測定する計測器などが挙げられる。補助計測用プローブ３ｂを具備し、常に近赤外分光プローブ３ａと共に稼働させ比較することで、近赤外分光プローブ３ａから何らかの理由で適正な含水率が得られなくても、補完するデータを補助計測用プローブ３ｂから得ることができる。これにより、データ欠損を防ぐことができる。同様に、近赤外分光プローブ３ａを用いて測定された含水率と補助計測用プローブ３ｂを用いて測定された含水率との比較から、脱水汚泥１の深さの変更あるいは、近赤外分光器３または補助計測器３’の交換、あるいは脱水プロセス条件の変更が必要であることが判断でき、メンテナンス方針策定に役立てることができる（（ｖｉ）で詳述。）。 In the above, since the dehydrated sludge 1 inside the dehydrated sludge 1 to be collected is collected and measured, the measurement accuracy of the water content of the dehydrated sludge 1 can be improved. Furthermore, in the above, since the sampling mechanism (sampling section 11) and measuring mechanism (measuring section 12) of the jig 2 are integrated, it takes only a short time from sampling to measurement, and the dehydrated sludge 1 is kept as air-free as possible. The structure is such that it cannot be touched. Thereby, fluctuations in the water content can be suppressed and the water content can be obtained with high accuracy. Further, a light shielding enclosure (that is, a light shielding section that shields the sampling section 11 and the measuring section 12 from light) may be provided in the sampling unit 2a. This allows spectroscopic measurement even if the sludge dewatering sampling location is a location where light cannot be blocked.
(6) Obtain measurement information F1 from the auxiliary measurement probe 3b at the same time as the near-infrared spectroscopy probe 3a (obtain measurement information F1 from the auxiliary measurement probe 3b via the auxiliary measuring instrument 3'). Examples of the auxiliary measuring device 3' include a measuring device for measuring bulk weight and viscosity. Equipped with an auxiliary measurement probe 3b, which is always operated together with the near-infrared spectroscopy probe 3a for comparison, it is possible to supplement data even if the near-infrared spectroscopy probe 3a cannot obtain an appropriate water content for some reason. It can be obtained from the measurement probe 3b. This can prevent data loss. Similarly, from a comparison of the water content measured using the near-infrared spectroscopy probe 3a and the water content measured using the auxiliary measurement probe 3b, it is possible to change the depth of the dehydrated sludge 1 or It can be determined that the instrument 3 or the auxiliary measuring instrument 3' needs to be replaced, or that the dehydration process conditions need to be changed, which can be useful in formulating a maintenance policy (described in detail in (vi)).
　（iii)治具による採取した脱水汚泥の廃棄
　治具２で採取した脱水汚泥１の廃棄方法について図３及び図４を用いて説明する。図３の状態ＯＰ５に示すように、治具２で採取した脱水汚泥１の計測が終了後（上蓋２ｂはすでに計測時に後方にスライドされている）、サンプリングユニット２ａの底蓋２ｃ及び採取部材２ｄをそれぞれ独立した第３駆動機構及び第１駆動機構によって、採取した脱水汚泥１に対して後方にスライドさせる。 (iii) Disposal of dehydrated sludge collected using the jig A method for disposing of the dehydrated sludge 1 collected using the jig 2 will be explained using FIGS. 3 and 4. As shown in state OP5 of FIG. 3, after the measurement of the dehydrated sludge 1 collected with the jig 2 is completed (the top cover 2b has already been slid backward during measurement), the bottom cover 2c of the sampling unit 2a and the sampling member 2d is slid rearward with respect to the collected dewatered sludge 1 by a third drive mechanism and a first drive mechanism, which are independent from each other.
　具体的に述べると、状態ＯＰ５にて、第１ピストンロッド３１が後方向に縮むことにより、採取部材２ｄを採取した脱水汚泥１に対して後方にスライドして（ずらして）、第３ピストンロッド３３が後方向に縮むことにより、底蓋２ｃを採取した脱水汚泥１に対して後方にスライドする（ずらす。）。そうすることで、図３の状態ＯＰ６及び図４に示すように、採取した脱水汚泥１を囲む面（壁や底）が無くなるため、脱水汚泥１は下に自重で落下する。 Specifically, in state OP5, the first piston rod 31 contracts in the backward direction, so that the collection member 2d slides (displaces) backward with respect to the collected dehydrated sludge 1, and the third piston rod 33 contracts in the backward direction, the bottom cover 2c slides (shifts) backward with respect to the collected dehydrated sludge 1. By doing so, as shown in state OP6 of FIG. 3 and FIG. 4, there is no surface (wall or bottom) surrounding the collected dehydrated sludge 1, so the dehydrated sludge 1 falls downward under its own weight.
　なお、状態ＯＰ４にて、第１ピストンロッド３１が後方向に縮むことにより、採取部材２ｄを採取した脱水汚泥１に対して後方に移動させた場合、状態ＯＰ５にて採取部材２ｄは既に脱水汚泥１に対して後方にスライドされている。よって、この場合、第３ピストンロッド３３のみが後方向に縮むことにより、底蓋２ｃを採取した脱水汚泥１に対して後方にスライドする（ずらす。）。これにより、脱水汚泥１を下に自重で落下させる。 Note that in state OP4, when the first piston rod 31 contracts backward and the collecting member 2d is moved backward with respect to the collected dehydrated sludge 1, in state OP5, the collecting member 2d has already collected the dehydrated sludge. It has been slid backwards relative to 1. Therefore, in this case, only the third piston rod 33 contracts in the rearward direction, thereby sliding (shifting) the bottom cover 2c rearward with respect to the collected dehydrated sludge 1. This causes the dehydrated sludge 1 to fall downward under its own weight.
　また、上蓋２ｂ、底蓋２ｃ及び断面がコ字状の採取部材２ｄに少量でも脱水汚泥１が付着していると次の測定に影響するため、図５に示すように、治具２の内部の格納場所から上蓋２ｂ、底蓋２ｃ及び断面がコ字状の採取部材２ｄを出し入れする部分に小さなブラシ２ｊ等が設けられていてもよい。ブラシ２ｊにより、上蓋２ｂ、底蓋２ｃ及び断面がコ字状の採取部材２ｄに付着した脱水汚泥１を掻き落とすことができる。なお、ブラシ２ｊを設けた場合において、図６に示すように、ブラシ２ｊの取り付け板２ｋが設けられてもよい。 Furthermore, if even a small amount of dehydrated sludge 1 adheres to the top cover 2b, bottom cover 2c, and collection member 2d having a U-shaped cross section, it will affect the next measurement. A small brush 2j or the like may be provided at a portion where the top cover 2b, bottom cover 2c, and collection member 2d having a U-shaped cross section are taken in and out from the storage location. The brush 2j can scrape off the dehydrated sludge 1 adhering to the top lid 2b, bottom lid 2c, and collection member 2d having a U-shaped cross section. In addition, when the brush 2j is provided, as shown in FIG. 6, a mounting plate 2k for the brush 2j may be provided.
　脱水汚泥１が圧縮され、平坦化された後、サンプリングユニット２ａの底蓋２ｃ及び先端正面を除くコ字状の採取部材２ｄに強く付着することがある。これは、脱水汚泥１に多く含まれるZoogloeaという微生物が多糖類状の物質を産生するからである(非特許文献１：A. B. Norberg and S. Enfors,“Production of Extracellular Polysaccharide by Zoogloea ramigera,”Applied and Environmental Microbiology, vol. 44, no. 5, pp.1231-1237, 1982.を参照。)。この場合、後方から、速乾性のエタノールやフッ素溶剤などをかけて洗浄して除去することができる。それでも脱水汚泥１が除去困難な場合、上記洗浄剤を添加するとともに、上蓋２ｂ、底蓋２ｃ及び断面がコ字状の採取部材２ｄに超音波を印加するなどしても良い。治具２自体に超音波機構が搭載されてもよく、この場合、除去のために治具２を取り外す作業が不要となるため好ましい。 After the dehydrated sludge 1 is compressed and flattened, it may strongly adhere to the bottom cover 2c of the sampling unit 2a and the U-shaped sampling member 2d excluding the front end. This is because the microorganism called Zoogloea, which is abundant in dehydrated sludge 1, produces polysaccharide-like substances (Non-Patent Document 1: A. B. Norberg and S. Enfors, “Production of Extracellular Polysaccharide by Zoogloea ramigera,” ”Applied and Environmental Microbiology, vol. 44, no. 5, pp. 1231-1237, 1982.) In this case, it can be removed by washing with quick-drying ethanol, fluorine solvent, etc. from the rear. If the dehydrated sludge 1 is still difficult to remove, the cleaning agent may be added and ultrasonic waves may be applied to the top lid 2b, bottom lid 2c, and collection member 2d having a U-shaped cross section. An ultrasonic mechanism may be mounted on the jig 2 itself, and in this case, it is preferable because there is no need to remove the jig 2 for removal.
　（iv）治具の主要構成部品の素材
　脱水汚泥１の採取及び計測、並びに廃棄のプロセスを踏まえ、脱水汚泥１と接触する上蓋２ｂ、底蓋２ｃ及び断面がコ字状の採取部材２ｄの素材は、脱水汚泥１が付着しにくく、かつ水分を透過させない素材であることが好ましい。さらに、脱水汚泥１及び水分に長時間接した場合に劣化や溶出が少ないことが好ましい。素材の例として、テフロン（登録商標）樹脂、ＰＦＡ樹脂がある。また、素材は、例えば、ガラスや石英などの素材にあらかじめフッ素溶剤等をコーティングしたものであってもよい。 (iv) Materials for the main components of the jig Based on the process of collecting, measuring, and disposing of the dehydrated sludge 1, the materials of the top cover 2b, bottom cover 2c, and collection member 2d with a U-shaped cross section that come into contact with the dehydrated sludge 1 are considered. It is preferable that the material is a material to which the dehydrated sludge 1 is difficult to adhere and which does not allow moisture to pass through. Furthermore, it is preferable that there is little deterioration or elution when in contact with the dehydrated sludge 1 and moisture for a long time. Examples of materials include Teflon (registered trademark) resin and PFA resin. Further, the material may be, for example, a material such as glass or quartz coated with a fluorine solvent or the like in advance.
　（ｖ）治具による計測情報と演算処理
　治具２で得られた計測情報と演算処理について図７Ａを用いて説明する。治具２による脱水汚泥計測Ｃ１において上記（ii）（５）で得られた近赤外分光プローブ３ａ及び補助計測用プローブ３ｂから得られた計測情報Ｆ１を運転支援ナビシステムＧ１に自動で送信する。送信された計測情報Ｆ１に基づき運転支援ナビシステムＧ１において自動で演算処理して脱水汚泥１の含水率を得る。この時の含水率は、近赤外分光プローブ３ａ及び補助計測用プローブ３ｂからそれぞれ得た計測情報に基づく演算値である２種類の含水率を指す。また、計測情報Ｆ１及び前記含水率は運転支援ナビシステムＧ１内の演算結果表示部Ｈ１に表示され、データ格納部Ｊ１に格納され、蓄積されていく。また、運転支援ナビシステムＧ１から含水率（Ｆ１’）を治具２に送信し、治具２の含水率表示部３ｃに表示しても良い。 (v) Measurement information and arithmetic processing by the jig The measurement information and arithmetic processing obtained by the jig 2 will be explained using FIG. 7A. In the dehydrated sludge measurement C1 using the jig 2, the measurement information F1 obtained from the near-infrared spectroscopy probe 3a and the auxiliary measurement probe 3b obtained in (ii) and (5) above is automatically transmitted to the driving support navigation system G1. . Based on the transmitted measurement information F1, the driving support navigation system G1 automatically performs arithmetic processing to obtain the water content of the dehydrated sludge 1. The water content at this time refers to two types of water content that are calculated values based on measurement information obtained from the near-infrared spectroscopy probe 3a and the auxiliary measurement probe 3b, respectively. Further, the measurement information F1 and the moisture content are displayed on the calculation result display section H1 in the driving support navigation system G1, and are stored and accumulated in the data storage section J1. Further, the water content (F1') may be transmitted from the driving support navigation system G1 to the jig 2 and displayed on the water content display section 3c of the jig 2.

These are communicably connected to each other via a bus 217. Note that the storage device (HDD) 214 is not limited to an HDD (Hard Disk Drive), and may be, for example, a flash memory such as an SSD (Solid State Drive).
　ＣＰＵ２１１は、ＲＯＭ２１２及び／又はＨＤＤ２１４に格納された図示しない各種プログラムをＲＡＭ２１３にロードし、ＲＡＭ２１３にロードされたプログラムを実行することによって、各種機能を実現する。ＲＡＭ２１３には、上述したようにＣＰＵ２１１が実行する各種プログラムがロードされ、ＣＰＵ２１１が各種プログラムを実行する際に使用するデータが一時的に記憶される。ＲＯＭ２１２及び／又はＨＤＤ２１４は不揮発性の記憶媒体であり、ＲＯＭ２１２及び／又はＨＤＤ２１４には各種プログラムが記憶されている。ネットワークインタフェース２１５は、運転支援ナビシステムＧ１がネットワークＮＷ１に接続されるためのインタフェースである。入出力インタフェース２１６は、キーボード及び表示装置２２０等に接続されるためのインタフェースである。 The CPU 211 loads various programs (not shown) stored in the ROM 212 and/or HDD 214 into the RAM 213, and executes the programs loaded into the RAM 213, thereby realizing various functions. As described above, various programs executed by the CPU 211 are loaded into the RAM 213, and data used when the CPU 211 executes the various programs is temporarily stored.

　（vi）含水率に基づくフィードバックシステム
　含水率に基づくフィードバックシステムについて図８Ａ乃至図１１で以下説明する。図８Ａは、含水率に基づく半自動の運転支援ナビシステムＧ１について示す図である。治具２で計測され、運転支援ナビシステムＧ１で演算された含水率に基づき、運転支援ナビシステムＧ１は、治具２の脱水汚泥１の採取位置（深さ）や汚泥５の脱水プロセス制御にフィードバックする機能を有する。 (vi) Feedback system based on moisture content A feedback system based on moisture content will be described below with reference to FIGS. 8A to 11. FIG. 8A is a diagram illustrating a semi-automatic driving support navigation system G1 based on moisture content. Based on the moisture content measured by the jig 2 and calculated by the driving support navigation system G1, the driving support navigation system G1 determines the sampling position (depth) of the dehydrated sludge 1 of the jig 2 and the dewatering process control of the sludge 5. Has a feedback function.
　運転支援ナビシステムＧ１は、治具２の近赤外分光プローブ３ａの計測情報に基づく含水率（以下、「含水率Ａ」と称呼される。）及び補助計測用プローブ３ｂの計測情報に基づく含水率（以下、「含水率Ｂ」と称呼される。）に基づいて、以下に述べるフィードバック（制御）を行う。 The driving support navigation system G1 determines the water content based on the measurement information of the near-infrared spectroscopic probe 3a of the jig 2 (hereinafter referred to as "moisture content A") and the water content based on the measurement information of the auxiliary measurement probe 3b. The feedback (control) described below is performed based on the moisture content (hereinafter referred to as "moisture content B").
　運転支援ナビシステムＧ１は、含水率Ａと第１予測値とを比較し、含水率Ｂと第２予測値とを比較し、含水率Ａと第１予測値との比較結果及び含水率Ｂと第２予測値との比較結果に応じた制御を行う。 The driving support navigation system G1 compares the moisture content A with the first predicted value, compares the moisture content B with the second predicted value, and compares the moisture content A with the first predicted value and the moisture content B. Control is performed according to the comparison result with the second predicted value.
　即ち、運転支援ナビシステムＧ１は、含水率Ａが第１予測値に基づく第１予測値範囲内にあるか否かを判定し、含水率Ｂが第２予測値に基づく第２予測値範囲内にあるか否かを判定し、含水率Ａと第１予測値との比較結果及び含水率Ｂと第２予測値との比較結果に応じた制御を行う。なお、第１予測値及び第１予測値範囲は、過去のデータに基づいて設定される値及び範囲であり、第１予測値範囲は、第１予測値からの測定誤差を含む範囲である。第１予測値範囲は、「第１予測範囲」とも称呼される場合がある。第２予測値及び第２予測値範囲は、過去のデータに基づいて設定される値及び範囲であり、第２予測値範囲は、第２予測値からの測定誤差を含む範囲である。第２予測値範囲は、「第２予測範囲」とも称呼される場合がある。 That is, the driving support navigation system G1 determines whether the moisture content A is within the first predicted value range based on the first predicted value, and determines whether the moisture content B is within the second predicted value range based on the second predicted value. , and performs control according to the comparison result between the moisture content A and the first predicted value and the comparison result between the moisture content B and the second predicted value. Note that the first predicted value and the first predicted value range are values and ranges set based on past data, and the first predicted value range is a range that includes a measurement error from the first predicted value. The first predicted value range may also be referred to as a "first predicted range." The second predicted value and the second predicted value range are values and ranges set based on past data, and the second predicted value range is a range that includes a measurement error from the second predicted value. The second predicted value range may also be referred to as a "second predicted range."
　なお、以下の説明において、「含水率Ａが予測値から逸脱している」とは、含水率Ａが第１予測値範囲内ではないことを意味する。「含水率Ｂが予測値から逸脱している」とは、含水率Ｂが第２予測値範囲内ではないことを意味する。
（１）近赤外分光プローブ３ａから得られた含水率のみが予測値から逸脱していた場合
　近赤外分光プローブ３ａから得られた含水率Ａのみが予測値から逸脱していた場合、運転支援ナビシステムＧ１が、治具２の脱水汚泥１の採取位置（深さ）を変えるよう求める運転案提示Ｋ１を運転支援ナビシステムＧ１内の演算結果表示部Ｈ１に表示したうえで、採取深さを自動で制御する（Ｆ１’）。なお、この制御は、「制御Ａ」又は「第１制御」とも称呼される。なお、制御Ａでは、採取深さの自動制御が実行されずに、治具２の脱水汚泥１の採取位置（深さ）を変えるよう求める運転案提示Ｋ１を演算結果表示部Ｈ１に表示することのみが実行されてもよい。この場合、演算結果表示部Ｈ１を見た現場作業者Ｌ１が手動で操作Ｍ１を実施し採取深さを調整することも可能である。 In the following description, "the moisture content A deviates from the predicted value" means that the moisture content A is not within the first predicted value range. "The moisture content B deviates from the predicted value" means that the moisture content B is not within the second predicted value range.
(1) When only the water content obtained from the near-infrared spectroscopy probe 3a deviates from the predicted value If only the water content A obtained from the near-infrared spectroscopy probe 3a deviates from the predicted value, the operation The support navigation system G1 displays a driving plan presentation K1 requesting to change the sampling position (depth) of the dehydrated sludge 1 of the jig 2 on the calculation result display section H1 in the driving support navigation system G1, and then displays the driving plan presentation K1 requesting to change the sampling position (depth) of the dehydrated sludge 1 of the jig 2. is automatically controlled (F1'). Note that this control is also referred to as "control A" or "first control." In addition, in control A, automatic control of the sampling depth is not executed, and an operation plan presentation K1 requesting to change the sampling position (depth) of the dehydrated sludge 1 of the jig 2 is displayed on the calculation result display section H1. may only be executed. In this case, it is also possible for the field worker L1 who sees the calculation result display section H1 to manually perform the operation M1 to adjust the sampling depth.
　再測定後も含水率の状態に変化が無い場合は、近赤外分光器３及び／又は近赤外分光プローブ３ａの交換を促すように求める運転案提示Ｋ１が、運転支援ナビシステムＧ１内の演算結果表示部Ｈ１に表示される。この場合、運転案提示Ｋ１を見た現場作業者Ｌ１が、運転案提示Ｋ１に従って操作Ｍ１である近赤外分光器３及び／又は近赤外分光プローブ３ａの交換作業を実施する。なお、制御Ａでは、運転支援ナビシステムＧ１から治具２にフィードバックして交換を促す信号（画像）が、含水率表示部３ｃに表示されるようにしてもよい。これにより、近赤外分光器３及び／又は近赤外分光プローブ３ａの交換を促す旨を、現場作業者Ｌ１に通知することができる。
（２）補助計測用プローブ３ｂから得られた含水率Ｂのみが予測値から逸脱していた場合
　補助計測用プローブ３ｂから得られた含水率Ｂのみが予測値から逸脱していた場合、運転支援ナビシステムＧ１から、補助計測器３’及び／又は補助計測用プローブ３ｂの交換を促す運転案提示Ｋ１を運転支援ナビシステムＧ１内の演算結果表示部Ｈ１に表示する。なお、この制御は、「制御Ｂ」又は「第２制御」とも称呼される。 If there is no change in the water content state even after re-measurement, a driving suggestion presentation K1 prompting to replace the near-infrared spectrometer 3 and/or near-infrared spectroscopic probe 3a is displayed in the driving support navigation system G1. It is displayed on the calculation result display section H1. In this case, the field worker L1 who has viewed the driving plan presentation K1 performs the operation M1, which is the replacement work of the near-infrared spectrometer 3 and/or the near-infrared spectroscopic probe 3a, in accordance with the driving plan presentation K1. In addition, in control A, a signal (image) that is fed back from the driving support navigation system G1 to the jig 2 to prompt replacement may be displayed on the moisture content display section 3c. Thereby, it is possible to notify the field worker L1 that the near-infrared spectrometer 3 and/or the near-infrared spectroscopic probe 3a should be replaced.
(2) When only the moisture content B obtained from the auxiliary measurement probe 3b deviates from the predicted value If only the moisture content B obtained from the auxiliary measurement probe 3b deviates from the predicted value, driving support From the navigation system G1, a driving suggestion presentation K1 urging replacement of the auxiliary measuring device 3' and/or the auxiliary measuring probe 3b is displayed on the calculation result display section H1 in the driving support navigation system G1. Note that this control is also referred to as "control B" or "second control."
　これにより、演算結果表示部Ｈ１を見る現場作業者Ｌ１に、補助計測器３’及び／又は補助計測用プローブ３ｂの交換を促すことができる。演算結果表示部Ｈ１を見た現場作業者Ｌ１は操作Ｍ１である交換作業を実施する。なお、制御Ｂでは、運転支援ナビシステムＧ１から治具２にフィードバックして交換を促す信号（画像）が、含水率表示部３ｃに表示されるようにしてもよい。これにより、補助計測器３’及び／又は補助計測用プローブ３ｂの交換を促す旨を現場作業者Ｌ１に通知することができる。
（３）近赤外分光プローブ３ａ及び補助計測用プローブ３ｂから得られた含水率が共に予測値から逸脱していた場合
　近赤外分光プローブ３ａ及び補助計測用プローブ３ｂから得られた含水率が共に予測値から逸脱していた場合、例えば運転支援ナビシステムＧ１内から、治具２の脱水汚泥１の採取位置（深さ）を変えるように求める運転案提示Ｋ１を運転支援ナビシステムＧ１内の演算結果表示部Ｈ１に表示したうえで、自動で採取深さを自動で制御する（Ｆ１’）。なお、この制御は、「制御Ｃ」又は「第３制御」とも称呼される。なお、制御Ｃでは、採取深さの自動制御が実行されずに、治具２の脱水汚泥１の採取位置（深さ）を変えるように求める運転案提示Ｋ１を演算結果表示部Ｈ１に表示することのみが実行されるようにしてもよい。この場合、演算結果表示部Ｈ１を見た現場作業者Ｌ１が手動で操作Ｍ１を実施し採取深さを調整することも可能である。 Thereby, the field worker L1 who looks at the calculation result display section H1 can be prompted to replace the auxiliary measuring device 3' and/or the auxiliary measuring probe 3b. The field worker L1 who sees the calculation result display section H1 performs the replacement work that is operation M1. In addition, in control B, a signal (image) that is fed back from the driving support navigation system G1 to the jig 2 to prompt replacement may be displayed on the moisture content display section 3c. Thereby, it is possible to notify the field worker L1 that the auxiliary measuring device 3' and/or the auxiliary measuring probe 3b should be replaced.
(3) When the water content obtained from the near-infrared spectroscopic probe 3a and the auxiliary measurement probe 3b both deviate from the predicted value The water content obtained from the near-infrared spectroscopic probe 3a and the auxiliary measurement probe 3b If both of them deviate from the predicted values, for example, from within the driving support navigation system G1, a driving suggestion presentation K1 requesting to change the sampling position (depth) of the dehydrated sludge 1 of the jig 2 is sent to the driving support navigation system G1. After displaying the calculation result on the calculation result display section H1, the sampling depth is automatically controlled (F1'). Note that this control is also referred to as "control C" or "third control." In addition, in control C, automatic control of the sampling depth is not executed, and an operation plan presentation K1 requesting to change the sampling position (depth) of the dehydrated sludge 1 of the jig 2 is displayed on the calculation result display section H1. It may also be possible to only execute the following. In this case, it is also possible for the field worker L1 who sees the calculation result display section H1 to manually perform the operation M1 to adjust the sampling depth.
　調整後も含水率の状態に変化が無い場合は運転支援ナビシステムＧ１内から汚泥の脱水条件を、変更を求める運転案提示Ｋ１を実施し、現場作業者Ｌ１は運転案提示Ｋ１に基づき操作Ｍ１を実施し、汚泥の脱水条件を調整して好適化する。 If there is no change in the water content state after adjustment, the driving support navigation system G1 executes a driving plan presentation K1 requesting a change in the sludge dehydration conditions, and the field worker L1 performs operation M1 based on the driving plan presentation K1. and adjust and optimize the sludge dewatering conditions.
