ことは公知であり、この場合に濁度検出器を処理水中で
上下に移動させ、所要の深さの濁度を検出して表示させ
ることも一般的に行われている。Conventionally, the concentration of treated water in a sedimentation tank or the like has been determined by an optical method, for example, by using a light emitting diode as a light emitting element and a phototransistor as a light receiving element, and converting the output of this phototransistor in an analog-to-digital converter. It is well known that the obtained voltage is displayed on a digital display, and in this case, it is also common to move the turbidity detector up and down in the treated water to detect and display the turbidity at the desired depth. is being carried out.

刻々変化しているから、所要の深さにおいて濁度検出器
が検出する濁度もこれに対応して変化し、デジタル表示
部に例えば数字等で表わされる表示もこれに応じて変化
する。The turbidity of treated water in sedimentation tanks is non-uniform due to the suspension of fine particles such as sludge, and it changes from moment to moment depending on temperature and other conditions. The degree also changes accordingly, and the display represented by, for example, numbers on the digital display also changes accordingly.

くの濁度が低いと見誤まり沈降度の不充分な汚泥を排出
したりするトラブルを発生するおそれがあった。If this display changes frequently, it becomes extremely difficult to read the display at a glance, and there is a problem in that the turbidity of the treated water at a required depth cannot be accurately determined. As a result, troubles may occur, such as taking in supernatant water with high turbidity, or discharging sludge with insufficient sedimentation because the turbidity near the sludge interface is mistakenly assumed to be low.
本発明は上記の問題点を解決し、測定した深さにおける
濁度の移動平均値を演算表示させることにより、処理水
の実際上の濁度に近似した濁度を容易且つ正確に識別で
きる表示装置を提供するものである。The present invention solves the above problems, and by calculating and displaying the moving average value of turbidity at the measured depth, the turbidity that approximates the actual turbidity of treated water can be easily and accurately identified. It provides equipment.

また、前記母数は、温度その他の外部条件に関連して設
定するようにしてもよい。The device of the present invention that achieves the above object is equipped with a turbidity detector and a depth sensor that move up and down in the treated water, and sends a detection signal of the turbidity of the treated water and a signal of its depth to a computer arithmetic control section. In the turbidity measurement and display device that displays the average value of input turbidity values on the display unit, a parameter for calculating the average value of input turbidity values is set in the calculation control unit in relation to the moving speed of the turbidity detector, and this parameter is set in the calculation control unit in relation to the moving speed of the turbidity detector. The moving average value is calculated using the cumulative total of the same number of turbidity values and the parameter, and this is displayed on the display unit along with the depth value1, and the parameter is , may be set in relation to temperature and other external conditions.
濁度検出器から送られる信号の濁度の値は処理水の濁度
の変化に対応して変化している。この各濁度の値が入力
してその数が設定母数と同数になると、この母数と各測
度の値の累計値によって濁度の平均値が演算される。こ
の場合、新しい濁度の値が送られると古い濁度の値が消
去して演算される。The turbidity value of the signal sent from the turbidity detector changes in response to changes in the turbidity of the treated water. When these turbidity values are input and their number becomes the same as the set parameter, the average value of turbidity is calculated based on the parameter and the cumulative value of each measurement value. In this case, when a new turbidity value is sent, the old turbidity value is deleted and calculated.
この母数は濁度検出器の移動スピードに関連させて設定

実際の濁度とほとんど等しくなって近似する。これは、
濁度検出塁が上下移動の折り返し点である汚泥界面近く
に一旦停止して測定する場合でも同様である。This parameter is set in relation to the moving speed of the turbidity detector, so the turbidity is detected when the turbidity detector is stationary in the supernatant water near the surface of the treated water and the moving speed is zero. When measuring, a large number of changed values of turbidity are taken in as calculation data of a moving average value, and the moving average value is almost equal to and approximates the actual turbidity of supernatant water. this is,
The same is true even when the turbidity detection base temporarily stops near the sludge interface, which is the turning point of vertical movement, and measures it.
また、濁度検出器を下降又は上昇させて測定するときは

動平均値が演算される。この値は測定した深さ域の濁度

異がなくこれに近似したものとなる。Also, when measuring by lowering or raising the turbidity detector, the parameter must be set to a smaller value, so it takes time to input each turbidity value and make it equal to the parameter. The moving average value is calculated immediately. Since this value is the average value of the turbidity in the measured depth range, it has almost no difference from the actual turbidity of the treated water and is close to it.
そして、表示部に表われる濁度の表示は、前記の演算に
より設定母数（変化した信号の回数）分の１となるから
、処理水の濃度が頻繁に変化してもこれが目まぐるしく
変わることはない。The turbidity displayed on the display will be 1/1 of the set parameter (the number of times the signal changes) due to the above calculation, so even if the concentration of the treated water changes frequently, it will not change rapidly. do not have.
以下、本発明の装置の一実施例を示す図面を参照してこ

ータ（Ｃ）の演算制御部１０に入力される。Figure 1 is a conceptual diagram of this device. In the figure, 1 is a turbidity detector, 2 is a cable suspending the turbidity detector, and 3 is a cable that moves the turbidity detector 1 up and down via the cable 2. This winder is equipped with a depth sensor, and the depth of the turbidity detector 1 in the treated water (W) in the sedimentation tank 4 (or concentration tank, wastewater treatment tank, etc.) is determined by the moving distance of the cable 2. The measured depth signal is input to the calculation control section 10 of the computer (C).

１０に入力されるようになっている。Further, the signal from the turbidity detector 1 sent through the cable 2 is input from the repeater 5 connected to the other end of the cable 2 to the analog-to-digital converter 11 of the computer (C), and is obtained through this conversion process. The calculated signal is input to the arithmetic control section 10.

This parameter is set by arbitrarily selecting the number of turbidity values for which the average value is to be obtained, that is, the number of times the turbidity signal changes, but in the present invention, the moving speed of the turbidity detector 1 It is set in relation to.
さらに具体的には、濁度検出器１が処理水（Ｗ）の液面
近くの上澄水中に待機状態にあるとき（第１図の１点鎖

ロとなる汚泥界面近くにあるときは、その母数を例えば
１００〜１２０程度に大きく設定し、濁度検出器１が下
降又は上昇しつつ濁度を検出する場合には、その母数は
それよりも少なくして（同等でもよい）設定しである。More specifically, when the turbidity detector 1 is in a standby state in the supernatant water near the liquid surface of the treated water (W) (the position indicated by the one-dot chain line in Fig. 1), or at the turning point of vertical movement. When the speed is near the sludge interface where the speed is zero, the parameter is set to be large, for example, about 100 to 120, and when the turbidity detector 1 detects turbidity while descending or rising, the parameter is is set to be less than (or even equal to) that value.
また、前記母数は、処理水（Ｗ）の注入後の経過時間、
温度、天候などの外部の諸条件に関連させて設定できる
ようにしてもよい。In addition, the parameter is the elapsed time after injection of the treated water (W),
It may also be possible to make settings in relation to external conditions such as temperature and weather.

れる。この場合、すでに入力した値によって母数と同数
になっているときに新たに変化した濁度の値が送られる
と、この値が入力され、最も最初に入力した値が消去さ
れる。Since the turbidity value of the signal sent from the turbidity detector 1 changes in response to changes in the turbidity of the treated water, each of these turbidity values is input and the number is the same as the set parameter. Then, the average value of turbidity is calculated using this parameter and the cumulative value of each turbidity value. In this case, if a newly changed turbidity value is sent when the already input value is the same as the parameter, this value will be input and the first input value will be deleted.
こうして演算された濁度の移動平均値の出力パルスは、
公知の計数回路等によって平均値に対応する電圧に変換

とき測定した深さも同時に表示されるようにしである。The output pulse of the moving average value of turbidity calculated in this way is
It is converted into a voltage corresponding to the average value by a known counting circuit or the like, and displayed as a number on the digital display section 12, and the measured depth is also displayed at the same time.
このため、ワインダ−３を作動させず濁度検出器１を処

度検出器１が上下移動の折り返し点である汚泥界面近く
に一旦停止して測定する場合でも同様である。Therefore, when measuring with the turbidity detector 1 in standby state in supernatant water near the surface of the treated water (W) without operating the winder 3, the parameter for calculating the average value is set to a large value. Because of this, many values of turbidity change are taken in as calculation data, and the moving average value is therefore very close to the actual turbidity of supernatant water. This is the same even when the turbidity detector 1 temporarily stops near the sludge interface, which is the turning point of vertical movement, and measures it.
また、ワインダー３を正転又は逆転させ、ケーブル２に

定した深さ域の濁度の平均値であるから、処理水の実際
の濁度とほとんど差異がなくこれに近似している。In addition, when measuring by rotating the winder 3 forward or reverse and lowering or raising the turbidity detector 1 using the cable 2, the parameter must be set smaller than the case described above, so each turbidity It does not take time for the degree value to be input and become the same as the parameter, and the moving average value is immediately calculated. Since this value is the average value of the turbidity in the measured depth range, it has almost no difference from the actual turbidity of the treated water and is close to it.

ことはない。The moving average value displayed on the digital display section 12 changes for each calculation, but since the change is 1/1 of the set parameter (number of times the signal changes), the treated water (W) is
) does not change rapidly even if its concentration changes frequently.

に変化してもその動的な平均値が表示される。In addition, since the parameter used to calculate the average turbidity value is related to the moving speed of the turbidity detector, an approximate value with almost no difference from the actual turbidity of the treated water in the measurement depth area will be displayed. At the same time, when a new turbidity value is sent, the old turbidity value is deleted and calculated, so even if the turbidity of the treated water changes from moment to moment, its dynamic average value is displayed.

ラブルを完全に防止できる効果がある。As described above, in the device of the present invention, the parameter for calculating the average value of turbidity is set in the calculation control section of the computer in relation to the moving speed of the turbidity detector, and this parameter and each input turbidity value are The moving average value is calculated based on the cumulative total of the values of , and this is displayed on the display together with the depth value, so even if the concentration of the treated water changes frequently, the change in the displayed turbidity value will be consistent with the setting standard. Since it is a fraction of the amount, the turbidity does not flicker to the eyes and cause difficulty in visual recognition, making it possible to reliably identify the turbidity. In addition, since this parameter is set in relation to the moving speed of the turbidity detector, it is possible to display an approximate value with almost no difference from the actual turbidity of the treated water in the measurement depth range. Especially when the turbidity detector is on standby in supernatant water or near the sludge interface, a large number of changed turbidity values are incorporated into the calculation of the moving average value, which approximates the actual turbidity. This has the effect of completely preventing troubles that could occur in the past.
