The details of the dust determination method in the target area will be described later with reference to FIG.

Details of the movement data generation method will be described later with reference to FIG.
- the standard movement amount calculation unit 104 specifies the speed at which waste is sent into the incinerator, that is, the dust feeding speed. Then, the standard movement amount calculation unit 104 uses the standard movement amount calculation formula 112 from the specified dust feeding speed to calculate the standard movement amount of the waste when the waste is sent into the incinerator at the specified dust feeding speed.

In addition, the influence prediction unit 106 may output the predicted value of the combustion state (for example, the predicted value of the lower heating value) as the prediction result. Prediction of the influence on the combustion state will be described later with reference to FIG.
- the equipment control unit 107 controls the equipment of the waste incineration facility based on the prediction results of the impact prediction unit 106. For example, the device control unit 107 controls (1) control of the introduction of waste into the hopper, (2) control of the speed of feeding dust, (3) control of the speed of conveying waste in the incinerator (grate speed), and (4) ) controlling the combustion of waste in the incinerator.

- garbage combustion control can be realized by, for example, controlling the amount of heating by a burner and the amount of combustion air supplied.
- the amount of combustion air supplied should be reduced.
- the garbage that appears when the hopper is photographed from above was in the garbage pit until immediately before, and it is possible to identify where in the garbage pit the garbage was picked up. Therefore, it is possible to predict the property distribution of the dust in the dust pit from the prediction result of the property prediction unit 105 or the prediction result of the influence prediction unit 106 .
- the device control unit 107 may control the agitation of the dust in the dust pit based on this property distribution.

- FIG. 3 is a diagram showing an example of a method for determining the presence or absence of dust.
- An image D shown in FIG. 3 is an image of the hopper taken from above. Image D shows dust sliding down the sloping surface of the hopper, but the entire sloping surface is not covered with dust. Specifically, dust is shown in the region d2 on the downstream side of the inclined surface of the hopper, but no dust is shown in the region d1 on the upstream side.
- the movement data generation unit 103 generates movement data for an area such as area d1 where no dust is shown, the amount of movement indicated by the movement data may be zero or a value close to zero. Then, when the movement amount becomes zero or a value close to zero, there is a possibility of outputting an erroneous prediction result for dust that does not actually exist.
- the prediction device 1 is equipped with a determination unit 102 .
- the determination unit 102 determines whether or not dust appears in the target area in the image.
- the movement data generation unit 103 generates movement data indicating the amount of movement between images in which the determination unit 102 determines that dust appears in the target area.
- an image in which an object is not shown in the target area is not used for predicting the properties of dust, so that the above-described erroneous prediction can be prevented.
- Whether or not dust is present may be determined using the photographed image, or may be determined after performing predetermined image processing on the photographed image to make it easier to determine the presence or absence of dust.
- Examples of the image processing include the Canny method.
- the Canny method is an algorithm for edge detection in images.
- An image D1 shown in FIG. 3 is an image generated by edge detection from the image D by the Canny method.
- the appearance of refuse is generally much more complex than the hopper surface geometry. For this reason, in the example of FIG. 3, a larger number of edges are detected in the area d2 where the dust appears compared to the area d1 where the dust does not appear.
- the determination unit 102 detects edges by applying the Canny method to an image of the hopper, and determines that an image in which the number of edges detected in the target region is equal to or greater than a threshold is an image containing dust. An image in which the number of edges detected in a is less than a threshold value may be determined as an image in which dust is not captured.
- the determination unit 102 may determine the presence or absence of dust by analyzing at least one of the luminance value and RGB value of each pixel forming the image. Further, for example, the determination unit 102 may determine the presence or absence of dust using a trained model (for example, a neural network model) that is trained to determine the presence or absence of dust.
- a trained model for example, a neural network model
- FIG. 4 is a diagram illustrating an example of a method of generating movement data. More specifically, FIG. 4 shows movement data indicating the state of movement of waste between an image E1 taken on the hopper slope at time t and an image E2 taken on the hopper slope at time t+ ⁇ t.
- An example of generating F by the image correlation method is shown.
- the y direction is the direction in which the waste descends, that is, the direction from the upstream side to the downstream side of the inclined surface of the hopper (see inclined surface A1 in FIG. 2)
- the x direction is the y direction on the inclined surface. It is the direction perpendicular to the direction.
- the image correlation method is a method of calculating the amount of movement of each particle in each image by image processing for two images in time series, and representing the calculated amount of movement as a vector. For example, in the image E1, the dust surrounded by the dashed line appears at the position e1, but in the image E2, it appears at the position e2 below the position e1. The moving state of this dust is expressed in the moving data F as a vector f1 indicating the displacement from the position e1 to the position e2. Also, vectors are similarly calculated for other positions.
- the movement data F represents the movement state of the dust at each position in the images E1 and E2. Specifically, from the movement data F, it can be seen that the dust at each position in the images E1 and E2 is moving in the y direction (downstream of the inclined surface of the hopper, that is, in the downward direction).
- vectors whose y-direction component values are equal to or greater than the threshold are indicated by solid-line arrows, and vectors whose values are less than the threshold are indicated by dashed-line arrows. This also shows that there are positions where the dust moves fast and positions where the dust moves slowly.
- the movement data generation unit 103 determines that the image elements appearing at each of a plurality of predetermined positions set on the inclined surface appearing in the images E1 and E2 are moved downward between the images E1 and E2. Movement data indicating the amount of movement may be generated.
- the sloping surface of the hopper On the sloping surface of the hopper, the refuse slides down in roughly the same descending direction, so the sloping surface of the hopper is a suitable position for judging whether the refuse is descending smoothly or stagnating. . Therefore, according to the above configuration, it is possible to generate movement data that accurately indicates whether the dust is descending smoothly or is stagnating. By predicting the properties of the dust using this movement data, highly reliable prediction can be performed. This is because, as described above, the difference in the properties of dust appears as the difference in the moving state of the dust reflected in the image.
- the movement data may also be collectively generated for image portions other than inclined surfaces.
- the property prediction unit 105 may predict the property of the dust using the movement data within the target area set to the portion where the inclined surface is shown, among the movement data generated by the movement data generation unit 103 .
- the target area may be the area in which the direction of movement of the dust is generally the same, and an area other than the inclined surface may be the target area.
- the area on the inner surface that connects with the inclined surface on the downstream side of the inclined surface (usually extending in the vertical direction) may be the target area.
- a region including both parts may be the target region.
- the movement data is not limited to the above examples as long as it indicates the movement state of the garbage.
- the speed of movement of dust may be used as movement data.
- a difference image showing the difference between two images taken at different times may be used as the movement data.
- FIG. 5 is a diagram showing the relationship between the dust feeding speed and the amount of movement.
- Graph H shown in Fig. 5 plots the amount of movement of various types of waste measured at various dust feeding speeds at a certain waste incineration facility.
- the upper side of the graph H shows a histogram h1 showing the distribution of the dust feeding speed
- the right side of the graph H shows a histogram h2 showing the distribution of the movement amount.
- the amount of movement is the amount of movement in the downward direction of the dust that appears between two time-series images of the dust.
- the prediction device 1 stores such a regression formula in the storage unit 11 as the standard movement amount calculation formula 112 .
- the property prediction unit 105 may calculate the difference between the movement amount indicated by the movement data generated by the movement data generation unit 103 and the standard movement amount of the dust as the prediction result.
- the difference between the amount of movement indicated by the movement data and the standard amount of movement indicates the flammability of the waste. Therefore, according to the above configuration, it is possible to calculate a value indicating the flammability of garbage as a prediction result.
- the movement amount indicated by the movement data generated by the movement data generation unit 103 is y1 when the current dust feeding speed is x1.
- a combination of the dust feeding speed and the movement amount is represented by a point h4 on the graph plane of the graph H in FIG.
- the impact prediction unit 106 may classify the dust according to the value of y' and output the classification result as the prediction result. For example, the effect prediction unit 106 may predict that there is an effect on the combustion state when the value of y' calculated by the property prediction unit 105 is plotted within the region h5 or h6. The influence prediction unit 106 may determine the magnitude of the influence according to the magnitude of the value of y'. Further, the influence prediction unit 106 may predict that there is no influence on the combustion state when plotted in the area between the areas h5 and h6.
- the combustion state prediction method is not limited to the above example, as long as a method suitable for the combustion state to be predicted is used as appropriate.
- the influence prediction unit 106 may predict the lower heating value. In this case, the correlation between the value of y' and the lower heating value should be formulated. Then, the effect prediction unit 106 may predict the lower heating value using the formula.
- the method of obtaining the standard movement amount is not limited to the above example.
- the dust feeding speed is divided into multiple numerical ranges, and the standard may be calculated in advance.
- the standard amount of movement may be, for example, the average value or median value of the amount of movement in each segment.
- the standard movement amount calculator 104 may specify the standard movement amount according to which category the current dust feeding speed belongs to.
- the standard amount of movement may be obtained using a non-linear model such as a neural network.
- a standard moving amount prediction model is prepared in advance by machine-learning the relationship between the dust feeding speed and the standard moving amount. Then, the standard movement amount calculation unit 104 may calculate the standard movement amount by inputting the dust feeding speed into this standard movement amount prediction model.
- FIG. 6 is a flowchart showing an example of processing executed by the prediction device 1. As shown in FIG. Note that the processing in FIG. 6 is performed, for example, each time the imaging device 2 captures a new image.
- the data acquisition unit 101 acquires time-series images of the hopper taken from above, and records them in the image DB 111 . As described above, these images are captured by the imaging device 2 (see FIG. 2), so the data acquisition unit 101 may acquire the images captured by the imaging device 2 .
- the determination unit 102 determines whether or not dust appears in the target area in the image acquired in S1.
- the method for determining whether or not dust appears in the target area is the same as described with reference to FIG. 3, so the description will not be repeated here. If the determination in S2 is YES, the process proceeds to S3, and if the determination in S2 is NO, the process of FIG. 6 ends.
- the movement data generation unit 103 In S3 (a step of generating movement data), the movement data generation unit 103 generates movement data indicating the movement state of the garbage to be incinerated from the image acquired in S1 and the image captured before the image. to generate For example, when an image shot at time t+ ⁇ t is acquired in S1, the movement data generation unit 103 reads the image shot at time t from the image DB 111 . Then, the movement data generation unit 103 generates movement data indicating the movement state of the dust during the period from time t to time t+ ⁇ t.

Description
(システム構成)
本実施形態に係る施設制御システム100の構成を図2に基づいて説明する。図2は、施設制御システム100の構成例を示す図である。図2には、施設制御システム100をごみ焼却施設に適用した例を示している。なお、施設制御システム100は、ごみに限られず任意の焼却対象物を焼却する任意の焼却施設に適用することができる。
図1に基づいて予測装置1の構成を説明する。図1は、予測装置1の要部構成の一例を示すブロック図である。図示のように、予測装置1は、予測装置1の各部を統括して制御する制御部10と、予測装置1が使用する各種データを記憶する記憶部11を備えている。また、予測装置1は、予測装置1が他の装置と通信するための通信部12、予測装置1に対する各種データの入力を受け付ける入力部13、予測装置1が各種データを出力するための出力部14を備えている。
判定部102によるごみの有無の判定について図3に基づいて説明する。図3は、ごみの有無の判定方法の例を示す図である。図3に示す画像Dは、ホッパを上方から撮影した画像である。画像Dには、ホッパの傾斜面を滑り落ちていくごみが写っているが、傾斜面の全体にごみが写っていはいない。具体的には、ホッパの傾斜面のうち下流側の領域d2にはごみが写っているが、上流側の領域d1にはごみは写っていない。
移動データ生成部103による移動データの生成方法について図4に基づいて説明する。図4は、移動データの生成方法の例を示す図である。より詳細には、図4には、時刻tにホッパの傾斜面上を撮影した画像E1と、時刻t+Δtにホッパの傾斜面上を撮影した画像E2との間におけるごみの移動状態を示す移動データFを、画像相関法により生成する例を示している。なお、図4において、y方向はごみが下降する方向、つまりホッパの傾斜面(図2の傾斜面A1参照)の上流側から下流側に向かう方向であり、x方向は上記傾斜面上におけるy方向に垂直な方向である。
標準移動量算出部104による標準移動量の算出方法と、性状予測部105によるごみの性状の予測方法と、影響予測部106による燃焼状態の予測について、図5に基づいて説明する。図5は、給じん速度と移動量の関係を示す図である。
予測装置1が実行する処理の流れ(予測方法)について図6に基づいて説明する。図6は、予測装置1が実行する処理の一例を示すフローチャートである。なお、図6の処理は、例えば、撮影装置2が新たな画像を撮影する毎に行われる。
本発明の他の実施形態について、以下に説明する。なお、説明の便宜上、上記実施形態にて説明した部材と同じ機能を有する部材については、同じ符号を付記し、その説明を繰り返さない。これは後述する実施形態3においても同様である。
図7は、本実施形態に係る予測装置1Aの要部構成の一例を示すブロック図である。予測装置1Aは、標準移動量算出部104を備えておらず、性状予測部105と影響予測部106の代わりに、かさ密度予測部(予測部)105Aと発熱量予測部106Aを備えている点で図1に示した予測装置1と相違している。また、予測装置1Aの記憶部11には、標準移動量算出式112が記憶されておらず、代わりにかさ密度予測式112Aと発熱量予測式113Aが記憶されている点でも予測装置1と相違している。
本発明の発明者らは、ごみの移動量と給じん速度を用いてかさ密度を表すことができないか検討した。この検討の結果、様々なかさ密度のごみについて、移動量と給じん速度を測定した結果を用いた重回帰分析により求めた下記の数式(1)によりかさ密度を予測することができることを見出した。
y=ax1+bx2+cx1*x2+d (1)
なお、上記数式(1)において、yはかさ密度[t/m3](tは質量の単位:トン)、x1は給じん速度[m/h]、X2はごみの移動量(画像相関法で算出した無次元量)であり、a~dは重回帰分析により求めた係数である。
y=ax1+b (2)
数式(2)によるかさ密度の予測値も、実際のかさ密度とある程度整合するものであったが、決定係数は数式(1)を用いた場合に及ばなかった。このことから、ごみの移動量がかさ密度の推定精度の向上に寄与していることがわかる。
発熱量予測部106Aによる低位発熱量の予測方法について、図9に基づいて説明する。図9は、低位発熱量の予測方法を説明する図である。また、図9には、図2に示したホッパAの下部の開口部A2付近の断面概略図もあわせて示している。
したがって、かさ密度は下記のように表される。
図9のKは、上記のようにして求めたかさ密度と、焼却炉Cにおけるその日の低位発熱量Huとの関係を示すグラフである。図示のように、ばらつきはあるものの、全体としてかさ密度と低位発熱量との間には相関があることがわかる。より詳細には、かさ密度と低位発熱量とは比例関係にあり、このため、かさ密度と低位発熱量との関係は直線k1で表すことができる。
予測装置1Aが実行する処理の流れ(予測方法)について図10に基づいて説明する。図10は、予測装置1Aが実行する処理の一例を示すフローチャートである。なお、図10のS11~S13の処理の説明は、図6のS1~3と同様であるから省略する。

施設制御装置1Bが実行する処理の流れ(施設制御方法)について図12に基づいて説明する。図12は、施設制御装置1Bが実行する処理の一例を示すフローチャートである。なお、図12のS21~S23の処理の説明は、図6のS1~3と同様であるから省略する。
ホッパでは、ホッパ内のごみが架橋状に詰まるブリッジが発生することがある。ブリッジが発生すると、ホッパの上部(ブリッジの発生箇所およびその上方)におけるごみの移動量は、ごみの性状によらず、著しく少なくなるか、あるいはゼロになる。したがって、ブリッジが発生しているときに撮影された画像からごみの性状を予測することは難しい。
上述の各実施形態で説明した各処理の実行主体は任意であり、上述の例に限られない。つまり、相互に通信可能な複数の装置により、予測装置1、1A、施設制御装置1Bと同様の機能を有するシステムを構築することができる。例えば、図6におけるS1~S3の処理をある情報処理装置に実行させ、生成された移動データを他の情報処理装置に送信して、当該他の情報処理装置によりS4~S8の処理を行うようにしてもよい。図9および図12に示す各処理についても同様である。
