Disclosure of Invention

Technical problem to be solved

In the above incineration facility, there is a possibility that a trouble may occur due to incineration of a substance mixed in the garbage and not suitable for incineration. Examples of such substances include mercury-containing substances which are not suitable for combustion, such as mercury thermometers, mercury sphygmomanometers, and fluorescent lamps. When mercury-containing substances unsuitable for combustion are incinerated, liquid mercury may vaporize and scatter, resulting in a dangerous state where the concentration of mercury in the exhaust gas transport path in the incinerator is high. In order to prevent the concentration from exceeding the discharge limit value, it is necessary to use a large amount of chemical agent to perform a treatment for reducing the mercury concentration in the exhaust gas. Further, when the mercury concentration in the exhaust gas exceeds the discharge limit value, it is necessary to stop the incineration and clean the exhaust gas transport path, which takes a lot of time and cost.

As a measure for preventing such a problem, it is conceivable to give attention or give a warning to a carrier who carries a substance unsuitable for combustion into an incineration facility. However, the conventional technique cannot identify a person who is not suitable for carrying a substance to be burned, and cannot effectively give attention or a warning. For example, although the technique of patent document 1 can predict the characteristics of the refuse material to some extent, it is impossible to identify a person who carries a material unsuitable for combustion, which is mixed with combustible refuse by intention or mistake.

An object of one embodiment of the present invention is to provide an information processing apparatus or the like capable of specifying a person who carries a substance that is not suitable for incineration.

(II) technical scheme

In order to solve the above-described problem, an information processing apparatus according to an aspect of the present invention includes: an arrival time prediction unit for calculating, for each of a plurality of carriers, arrival times at which refuse, which is carried by the plurality of carriers into an incineration facility for sending refuse in a refuse pit to an incinerator for incineration, arrives at a combustion position in the incinerator; and a carrier identification unit that identifies a carrier of the material that is not suitable for incineration, based on a time at which the material that is not suitable for incineration is detected in the incinerator and the arrival time calculated by the arrival time prediction unit.

In order to solve the above-described problem, an information processing method according to an aspect of the present invention is executed by an information processing apparatus, and includes: an arrival time prediction step of calculating, for each of a plurality of carriers, arrival times at which refuse, which is carried by the plurality of carriers into an incineration facility that sends refuse in a refuse pit to an incinerator for incineration, arrives at a combustion position in the incinerator; and a carrier specifying step of specifying a carrier of the material not suitable for incineration based on a time at which the material not suitable for incineration is detected in the incinerator and the arrival time calculated by the arrival time predicting step.

(III) advantageous effects

According to one embodiment of the present invention, it is possible to identify a carrier of a substance that is not suitable for incineration.

Detailed Description

(embodiment mode 1)

(general description of garbage incineration facility)

An outline of the waste incineration facility will be described with reference to fig. 2. Fig. 2 is a sectional view showing a schematic configuration of the waste incineration facility 100. As shown in fig. 2, the refuse incineration facility 100 includes each of a pre-refuse-collection measuring device 1, a refuse collection device 2, and an incinerator 3. The waste incineration facility 100 is provided with an operation room 8, and the operation room 8 is used for an operator to monitor the above-described devices or manually operate the crane 5.

In the pre-trash-receiving measuring device 1, the trash is measured before being carried into the trash receiving device 2, and various data related to the trash is generated. In the garbage receiving facility 2, the garbage carried in by the plurality of garbage collection vehicles Q is temporarily stored. The incinerator 3 is disposed in parallel with the garbage receiving apparatus 2 and incinerates garbage. A control system that communicates with each device and controls the waste incineration facility 100 as a whole is laid in the operation room 8. The operation room 8 is used for a user to monitor the state of each device (particularly, the inside of the pit 21) of the waste incineration facility 100 or to manually operate the crane 5.

(measuring apparatus before refuse reception 1)

The pre-garbage-collection measuring device 1 is installed before the garbage collection device 2, that is, in the vicinity of the entrance and exit of the garbage incineration facility 100. The measurement device 1 before refuse reception is provided with a carry-in person recognition device 12. The carry-in person recognition device 12 recognizes a carry-in person of the garbage loaded on the garbage collection vehicle Q. In addition, the category of "a carrier" includes not only an individual but also a worker (for example, a carrier worker). Then, the carrier identifying device 12 transmits information indicating the identified carrier to the information processing device 4. The method of identifying the carrier is not particularly limited. For example, the transporter identification device 12 may identify the transporter based on the identification information of the garbage collection vehicle Q by using information in which the identification information of the transporter of garbage and the identification information (for example, a vehicle number) of the garbage collection vehicle Q used by the transporter are associated with each other. For example, the carrier recognition device 12 may recognize the carrier by inputting the recognition information of the garbage carrier.

(refuse receptacle 2)

As shown in fig. 2, the garbage receiving apparatus 2 includes: a pit 21 for storing the garbage carried in by the garbage collection vehicle Q, and a hopper 22 for supplying the garbage in the pit 21 to the incinerator 3. The pit 21 is provided with a refuse inlet 24. In addition, a crane 5 for moving the garbage in the pit 21 is installed in the building of the pit 21. The refuse loaded by the refuse collection vehicle Q is thrown into the pit 21 from the loading port 24 and accumulated in the pit 21, and the refuse accumulated in the pit 21 is thrown into the hopper 22 by the crane 5. In addition, in the process of accumulating in the pit 21, the movement (also referred to as transfer or stirring) of the garbage is performed by the crane 5 for the purpose of equalizing the height of the garbage at each position in the pit 21, or equalizing the property of the garbage. Since the refuse loaded into the refuse incineration facility 100 by the refuse collection vehicle Q is directly thrown into the pit 21, a person who carries the refuse into the refuse incineration facility 100, that is, a person who carries the refuse into the pit 21.

(incinerator 3)

The incinerator 3 includes a combustion chamber 31 and a refuse guide passage 32. In addition, a mercury concentration sensor 33 is provided near the flue outlet of the incinerator 3 to detect the mercury concentration in the exhaust gas generated by incinerating the refuse. A filter type dust feeder, not shown, is provided in front of the flue outlet. The mercury concentration sensor 33 may be provided downstream of the filter type dust feeder (that is, after the outlet of the flue). In both cases where the mercury concentration sensor 33 is provided on the upstream side and the downstream side of the filter type refuse feeder, the delay in detection of mercury is of the order of several minutes. Therefore, in any case of the installation position of the mercury concentration sensor 33, the determination of the mercury-containing garbage carrying-in person, which will be described later, is not hindered.

The combustor 31 is, for example, a stokes-type (japanese original language: ストーカ -type) combustor. The refuse guide channel 32 is connected to the hopper 22. The refuse fed from the hopper 22 is guided to the combustion chamber 31 through the refuse guide passage 32.

(operation room 8)

The information processing device 4 and the incinerator control device 7 are disposed in the operation room 8. The location of the information processing device 4 is not particularly limited, and may be disposed outside the operation room 8.

The incinerator control device 7 controls the operation of each device included in the refuse incineration facility 100. The operator can control the operation of each device included in the waste incineration facility 100 via the incinerator control device 7. The incinerator control device 7 may have a function of automatically controlling the operation of each device.

Specifically, the incinerator control device 7 performs: the operation of the crane 5, the conveyance of the refuse fed to the hopper 22, the combustion of the refuse in the incinerator 3, and the like. Further, the respective controls may be performed by separate devices.

The information processing apparatus 4 detects the situation where the material unsuitable for incineration is incinerated in the waste incineration facility 100, and determines who the carrier of the material unsuitable for incineration is. Substances which are not suitable for incineration are: substances prohibited from being incinerated in the incinerator 3, or substances that are not preferred to be incinerated. For example, substances that generate toxic gases upon incineration (e.g., garbage containing chlorine, bromine, arsenic, etc.), substances that generate high temperatures upon incineration, substances that do not burn, substances that are flame retardant, and the like are all included in the category of substances that are not suitable for incineration. In the present embodiment, an example in which the substance that is not suitable for combustion is mercury-containing garbage will be described as an example. In addition, when a substance that generates toxic gas and is not suitable for incineration is incinerated at the time of incineration, a sensor for detecting toxic gas such as the mercury concentration sensor 33 described above may be used. In the case where substances unsuitable for incineration that affect the temperature in the incinerator 3 are incinerated, a sensor for detecting the temperature in the incinerator 3 may be used.

(configuration of information processing apparatus 4)

Fig. 1 is a block diagram showing an example of a main configuration of the information processing apparatus 4. As shown in the drawing, the information processing device 4 includes a control unit 40, a storage unit 41, an input unit 42, an output unit 43, and a communication unit 44. The control unit 40 controls each unit of the information processing apparatus 4 as a whole. The storage unit 41 stores various data used by the information processing apparatus 4. The input unit 42 receives an input operation of the information processing apparatus 4 by a user. The output unit 43 outputs various data. The output method is not particularly limited, and may be, for example, display output, audio output, or print output. The communication unit 44 is used for the information processing apparatus 4 to communicate with other apparatuses. The storage unit 41, the input unit 42, the output unit 43, and the communication unit 44 may be integrated with the information processing device 4, or may be externally provided to the information processing device 4.

The control unit 40 includes an entry monitoring unit 401, a movement monitoring unit 402, a drop monitoring unit 403, an arrival time predicting unit 404, a detecting unit 405, and an entry person specifying unit 406. The storage unit 41 stores garbage position information 411 and garbage input information 412.

The load monitoring unit 401 monitors the load of the refuse into the refuse incineration facility 100, and updates the refuse position information 411 based on the monitoring result. Specifically, the loading monitoring unit 401 detects loading of the refuse into the refuse incineration facility 100, and specifies a person who loads the refuse. As described with reference to fig. 2, the measurement device 1 before refuse reception is provided with the carrier recognition device 12, and the carrier recognition device 12 recognizes a carrier of refuse and transmits a recognition result to the information processing device 4. Therefore, the carry-in monitoring unit 401 can detect that garbage is carried in from the recognition result, and identify the person who carries the garbage. The carry-in monitoring unit 401 determines in which area of the pit 21 the refuse carried in and dropped into the pit 21 is located. Further, a detailed description of updating the trash position information 411 by the load monitoring unit 401 will be given later with reference to fig. 6.

The movement monitoring unit 402 monitors the movement of the dust in the pit 21 and updates the dust position information 411 based on the monitoring result. Specifically, the movement monitoring unit 402 detects that the refuse is moved by the crane 5 in the pit 21, and specifies the movement start point position and the movement end point position of the refuse. Then, the movement monitoring unit 402 updates the trash position information 411 based on the determination result. Further, a detailed description of updating the garbage position information 411 by the movement monitoring unit 402 will be given later with reference to fig. 7.

The input monitoring unit 403 monitors the input of the refuse from the pit 21 to the hopper 22, and updates the input refuse information 412 based on the monitoring result. Specifically, the input monitoring unit 403 detects the input of the refuse from the pit 21 to the hopper 22, and specifies the grasping position at which the refuse is grasped by the crane 5 at the time of the input. The input monitoring unit 403 specifies the carrier of the garbage at the pickup position with reference to the garbage position information 411, and updates the input garbage information 412 based on the specified result. The details of updating the input garbage information 412 will be described later with reference to fig. 8 and the like.

The arrival time predicting unit 404 calculates the time when the refuse fed into the hopper 22 reaches the combustion position in the incinerator 3 (hereinafter referred to as "combustion position arrival time"). More specifically, the arrival time prediction unit 404 calculates the combustion position arrival time of the refuse loaded by a plurality of loaders for each of the loaders. The method of calculating the combustion position arrival time will be described in detail later.

The detector 405 detects that substances unsuitable for incineration are incinerated in the incinerator 3, specifically, detects that mercury-containing garbage is incinerated. As described above, since the incinerator 3 is provided with the mercury concentration sensor 33, the detection unit 405 can detect that the garbage containing mercury is incinerated in the incinerator 3 when the detection value of the mercury concentration sensor 33 exceeds a predetermined threshold value.

The carrier identifying unit 406 identifies a carrier of the substances that are not suitable for incineration based on the detection time at which the detecting unit 405 detects incineration of the substances that are not suitable for incineration (mercury-containing garbage in the present embodiment) and the combustion position arrival time calculated by the arrival time predicting unit 404. The method for determining the carry-in person of the material unsuitable for incineration will be described in detail later.

As described above, the information processing apparatus 1 includes: an arrival time prediction unit 404 that calculates, for each of the carriers, arrival times at which the refuse carried in by the plurality of carriers arrives at the combustion positions; and a carrier specifying unit 406 that specifies a carrier of the material that is not suitable for incineration based on the time at which the material that is not suitable for incineration is detected and the arrival time. Therefore, it is possible to specify the carrier of the substances unsuitable for combustion, and to take measures such as a reminder and a warning for the specified carrier so as to prevent the carrier of the substances unsuitable for combustion from being carried again.

The garbage position information 411 is information indicating the position of the garbage carried in by each carrier in the pit 21. The garbage position information 411 is updated by (1) the loading monitoring unit 401 when garbage is loaded into the pit 21, and (2) the movement monitoring unit 402 when garbage is moved in the pit 21. Since the garbage position information 411 is updated as the state of the garbage in the pit 21 changes in this way, it can also be said that the information indicates the position transition of the garbage carried in by each carrier in the pit 21.

Then, the arrival time prediction unit 404 specifies the user who carries the mercury-containing garbage based on the garbage position information 411. As described above, the garbage position information 411 indicates the position transition of the garbage carried in by each carrier in the pit 21. Therefore, the user of the mercury-containing garbage can be identified based on the garbage position information 411, and the user of the mercury-containing garbage can be identified in consideration of, for example, the movement of the garbage in the pit 21 for transfer, stirring, or the like.

The input garbage information 412 is information on garbage records input into the hopper 22. For example, the refuse input information 412 may indicate at least a person who carries the refuse input to the hopper 22, the input time, and the arrival time of the combustion position of the refuse. The combustion position arrival time recorded in the input garbage information 412 is the predicted value calculated by the arrival time prediction unit 404.

(example of junk position information 411)

An example of the trash position information 411 will be described with reference to fig. 3. Fig. 3 is a diagram illustrating the trash position information 411. Fig. 3 (a) shows a case where pit 21 is viewed from above. Fig. 3 (a) also shows the hopper 22 and the carrying-in port 24. In this example, three carrying-in ports 24 are provided facing the pit 21 having a rectangular shape in plan view, and one hopper 22 is provided on the opposite side of the carrying-in ports 24 via the pit 21.

As shown in fig. 3 (a) and (b), in this example, the space in pit 21 is divided at equal intervals in each of the directions X (the width direction of pit 21), Y (the depth direction of pit 21), and Z (the depth direction of pit 21) to divide the space into a plurality of rectangular blocks. Thus, the position in pit 21 can be represented by a coordinate value of X, Y, Z. The size (width, depth, height) of the rectangular block is not particularly limited, and the rectangular block may be a cube having a length of 1m on one side, for example. In addition, the size of the rectangular block may be a size corresponding to a range of garbage that the crane 5 can lift in one grab.

Information indicating the garbage-carrying person is associated with the position of the rectangular block indicated by the coordinate value of X, Y, Z, whereby the position of the garbage carried by each person can be indicated in pit 21. For example, in the trash location information 411 in fig. 3 (c), the carrier a is associated with the location (1, 3). This indicates that the refuse transporter present at the lower left corner of fig. 3 (a) and having the third rectangular block from the bottom of pit 21 is transporter a.

In the trash location information 411 in fig. 3 (C), the carriers B and C are associated with the locations (2, 1, 3), and a ratio of 20% is associated with the carrier B and a ratio of 80% is associated with the carrier C. This means that when the total amount of garbage existing at the positions (2, 1, and 3) is set to 100%, the garbage carried in by the carrier B accounts for 20% of the total amount of garbage, and the garbage carried in by the carrier C accounts for 80% of the total amount of garbage. When garbage is thrown into the pit 21 or when garbage is moved in the pit 21, the garbage extends beyond the range of one rectangular block, and therefore there is a possibility that garbage carried in by a plurality of carriers may be mixed in one rectangular block.

(example of input garbage information 412)

An example of the garbage input information 412 will be described with reference to fig. 4. Fig. 4 is a diagram showing an example of the garbage input information 412. The garbage input information 412 shown in fig. 4 is information in which a garbage input number, a garbage input time, a combustion position arrival time, and a garbage input composition ratio of each of the carriers are associated.

The refuse input number is a number assigned to identify each of refuse inputs to the hopper 22 performed in the refuse incineration facility 100. The input timing is a timing when the garbage is input into the hopper 22. The input garbage number and the input time are recorded by the input monitoring unit 403.

The combustion position arrival time is a time when the refuse loaded into the hopper 22 arrives at the combustion position. The combustion position arrival time is calculated by the arrival time prediction unit 404 and recorded in the garbage input information 412.

The proportion of the refuse input by each transporter is a proportion of the refuse input by each transporter in the refuse input to the hopper 22. The input garbage composition ratio of each carrier is determined by the input monitoring unit 403 based on the garbage position information 411 and recorded in the input garbage information 412. Specifically, the garbage position information 411 records, for each position in the pit 21, a configuration ratio of a garbage transporter and a garbage transporter at the position (see fig. 3 (c)). Therefore, the input monitoring unit 403 can specify the proportion of the configuration of the input person and the input person of the refuse located at the refuse capture position of the input refuse based on the refuse position information 411, and can specify the proportion of the refuse input by each input person to the refuse input to the hopper 22 based on the specification result. For example, in the case of using the refuse position information 411 of fig. 3 (C), if the refuse capture position is (2, 1, 3), the input monitoring unit 403 can determine that 20% of the input refuse is input by the input user B and the remaining 80% is input by the input user C.

The carrier specification unit 406 refers to the input garbage information 412 and specifies the carrier of the mercury-containing garbage based on the detection time when the detection unit 405 detects the incineration of the mercury-containing garbage. For example, the detection unit 405 determines that the incineration time of the mercury-containing garbage is 14: 20. in this case, the carrier specification unit 406 specifies the combustion position arrival time ratio 14: 20 early and closest to 14: the entry 20 is the entry of the garbage number 3.

Here, in the input spam information 412 of fig. 4, a plurality of carriers are associated with one record. In this case, the transporter specifying unit 406 specifies the transporter of the mercury-containing refuse based on the proportion of the refuse transported by each transporter in the collection of refuse to be incinerated at the combustion position. The refuse once put into the hopper 22 is conveyed to the incineration position in a state of a fixed block (see fig. 5 described later). Therefore, the carrier specification unit 406 regards the proportion of the garbage carried in by each carrier in the set of garbage which is to be incinerated at the combustion position at the same time as the proportion of the garbage carried in by the input garbage information 412. Then, the carrier is determined based on the assumption. For example, the transporter specifying unit 406 may specify, as the transporter of the mercury-containing garbage, the transporter with the largest composition ratio (the transporter D in the record of the input garbage number 3) among the plurality of transporters indicated in the specified single record.

According to this configuration, even when a collection of refuse loaded by a plurality of carriers is to be incinerated at the same time at the combustion position due to transfer of refuse, stirring, or the like, an appropriate carrier can be determined based on the proportion of refuse loaded by each carrier.

(prediction of arrival time of Combustion site)

The case where the arrival time prediction unit 404 predicts the arrival time of the combustion position will be described with reference to fig. 5. Fig. 5 is a diagram illustrating a method of predicting the combustion position arrival time. Fig. 5 shows a cross section of the incinerator 3. As shown in the drawing, the garbage put into the hopper 22 is fed into the combustion chamber 31 through the garbage guide passage 32. A grate 34 for moving garbage is disposed in the combustion chamber 31, and the garbage moves through the grate 34 and is heated and incinerated on the grate 34.

In fig. 5, the garbage present in the section from the hopper 22 to the end of the grate 34 is divided into a1 to a 6. Each piece of garbage is the amount of garbage that is put into the hopper 22 by one time of grasping by the crane 5. The garbage a1 just loaded into the hopper 22 is fed to the grate 34 by a garbage feeder not shown. Therefore, the arrival time predicting unit 404 can predict the time required for the refuse a1 to move to the position of the refuse A3 shown in fig. 5, based on the conveying speed of the refuse feeding device. The arrival time predicting unit 404 can predict the time required for the refuse at the position of refuse A3 to reach the position of refuse a4 (combustion position) from the conveying speed of the grate 34.

Therefore, the arrival time prediction unit 404 can calculate the predicted value of the combustion position arrival time based on the time when the refuse is put into the hopper 22 and the moving condition (for example, the conveying speed of the refuse feeding device, the conveying speed of the grate 34, and the like) for moving the loaded refuse to the combustion position. According to this configuration, since the movement condition of the refuse put into the hopper 22 is taken into consideration, the appropriate arrival time can be calculated even when the movement condition is changed.

(update of garbage position information 411 with garbage in transit)

Updating of the trash position information 411 with the incoming trash will be described based on fig. 6. Fig. 6 is a flowchart showing a flow of updating the trash location information 411 with the incoming trash.

The loading monitoring unit 401 waits for the detection result of the measuring device 1 on the refuse collection vehicle before receiving the detection refuse (S1), and proceeds to the process of S2 when it is determined that the refuse collection vehicle is detected (yes in S1). For example, the carry-in monitoring unit 401 may determine that the refuse collection vehicle is detected when a notification is given from the carry-in person recognition device 12 of the pre-refuse-collection-related measuring facility 1.

At S2, the load monitoring unit 401 identifies the person who carried the garbage by the garbage collection vehicle detected at S1. For example, the inbound monitoring unit 401 may determine the inbound based on the content of the notification from the inbound identifying device 12. In the case where the transporter identification device 12 is not provided, the transporter monitoring unit 401 may identify the transporter by a method of acquiring an image of the refuse collection vehicle and analyzing the image.

In S3, the carry-in monitoring unit 401 specifies the position of the carried-in refuse in the pit 21. For example, as illustrated in fig. 3 (a), when there are a plurality of input ports 24, the input monitoring unit 401 determines which input port 24 the garbage collection vehicle has input the garbage. Then, the carry-in monitoring unit 401 specifies the position directly below the specified carry-in port 24 as the position of the carried-in refuse in the pit 21. Further, if what area the thrown-in refuse occupies in the pit 21 is modeled in advance, the area occupied by the carried-in refuse in the pit 21 can be specified by the model. In the present embodiment, as described with reference to fig. 3, the space in pit 21 is managed by being divided into a plurality of rectangular blocks, and therefore the above-described region can be expressed in units of rectangular blocks.

For example, the garbage thrown by one garbage collection vehicle occupies a rectangular area in the pit 21. In this case, when the garbage collection vehicle drops garbage from the inlet 24 at the left end in fig. 3 (a), the inlet monitoring unit 401 may determine that the X coordinate of the drop position is 3 and the Y coordinate is 1. Then, the carry-in monitoring unit 401 determines the position (value of Z coordinate) of the refuse dropped in the height direction, taking into account the height of the refuse deposited before dropping. For example, the height at which garbage has been deposited on two rectangular blocks (Z is 2) is set at a position where the X coordinate is 3 and the Y coordinate is 1. In this case, the carry-in monitoring unit 401 determines that the carried-in garbage is located at the position (3, 1, 3).

In S4, the load monitor 401 updates the trash position information 411 based on the determination results from S2 to S3. Specifically, the carry-in monitoring unit 401 adds the position specified in S3 to the trash position information 411, and records the carry-in person specified in S2 in association with the added position. After that, the process returns to S1.

The method of determining the position of the refuse carried in the pit 21 (the area occupied by the refuse in the pit 21) is not limited to the above example. For example, when the surface shape of the refuse in the pit 21 can be measured using a three-dimensional scanner or the like, the position of the refuse in the pit 21 (the area occupied in the pit 21) can be determined from the difference in the surface shape before and after the loading.

(update of garbage position information 411 with moving garbage)

Updating of the garbage position information 411 with moving garbage will be described based on fig. 7. Fig. 7 is a flowchart showing a flow of updating the garbage position information 411 with the moving garbage.

The movement monitoring unit 402 waits for movement of the refuse in the pit 21 (S11), and if it is determined that the refuse has moved (yes at S11), the process proceeds to S12. In S12, the movement monitoring unit 402 specifies the movement start point position and the movement end point position for each of the refuse determined to have moved in S11.

Here, the operation of the crane 5 is controlled by the incinerator control device 7. Therefore, the movement monitoring unit 402 can detect the movement of the refuse by the crane 5 and can specify the movement start point position and the movement end point position of the refuse by communicating with the incinerator control device 7, for example.

Then, in S13, the movement monitoring unit 402 updates the trash position information 411 based on the determination result of S12. Specifically, the movement monitoring unit 402 deletes the garbage information from the movement start position of the garbage and adds the garbage information to the movement end position in the garbage position information 411. After that, the process returns to S11. Similarly to the update of the trash position information 411 based on the above-described carrying in of the trash, if how the state of the trash at the movement start point and the movement end point of the trash changes is modeled in advance, the trash position information 411 can be updated based on the model.

(the garbage input information 412 is updated with the garbage input)

The following describes updating the garbage input information 412 with garbage input based on fig. 8. Fig. 8 is a flowchart showing a flow of updating the garbage input information 412 along with the garbage input.

The input monitoring unit 403 waits for the input of garbage into the hopper 22 (S21), and if it is determined that garbage is input (yes at S21), the process proceeds to S22 and thereafter. In S22, the input monitoring unit 403 specifies the input time, and in S23, specifies the garbage catching position at the time of input.

As described above, the operation of the crane 5 is controlled by the incinerator control device 7. Therefore, the input monitoring unit 403 can detect that the garbage is input by the crane 5 by communicating with the incinerator control device 7, for example, and can determine the detection time as the input time. The input monitoring unit 403 can also identify the position to catch the input garbage by communicating with the incinerator control device 7.

Then, in S24, the input monitoring unit 403 specifies the input garbage carrier based on the determination result in S23. Specifically, the input monitoring unit 403 refers to the refuse position information 411, identifies the person who carries the refuse at the refuse grasping position determined in S23, and identifies the person who carries the refuse as the person who carries the input refuse.

At S25, the input monitoring unit 403 adds the determination results at S22 and S24 to the input garbage information 412, and updates the input garbage information 412. After that, the process returns to S21.

(procedure for determining Mercury-containing garbage Carrier treatment)

A flow of processing for determining a carrier of mercury-containing garbage will be described with reference to fig. 9. Fig. 9 is a flowchart showing an example of a process (information processing method) for specifying a carrier of mercury-containing garbage. This treatment is performed after detecting the incineration of the mercury-containing garbage. The operation may be performed immediately after the detection, or may be performed at a time such as after the end of the operation of the waste incineration facility 100 on the same day as the detection.

In S31, the carrier specification unit 406 specifies the time at which the detection unit 405 detects the incineration of the mercury-containing garbage. Next, at S32 (arrival time prediction step), the arrival time prediction unit 404 specifies the travel condition of the refuse during the period from the time specified at S31 to a predetermined time before the time, and calculates the combustion position arrival time when the refuse introduced during the period is transported under the travel condition. The above period may be set to be longer than an upper limit time (a time required for conveying the refuse under the slowest conveying condition) from the start of the charging to the arrival of the combustion position. The movement conditions for each period may be recorded as history data in advance. By the processing at S32, the combustion position arrival time of the refuse carried in the period by the plurality of carriers is calculated for each carrier. The calculated combustion position arrival time is recorded in the garbage input information 412.

At S33 (a carrier identification step), the carrier identification unit 406 identifies a carrier of the mercury-containing garbage based on the incineration detection time of the mercury-containing garbage identified at S31 and the input garbage information 412. Thereby, the process of fig. 9 ends. The transporter specifying unit 406 may cause the output unit 43 to output the specified transporter, or may notify a predetermined notification destination (for example, a terminal device used by a manager of the waste incineration facility 100) via the communication unit 44.

Further, the method of determining the incorporators of the mercury-containing garbage is not limited to the above-described example. For example, the carrier specification unit 406 may calculate the arrival time of the combustion position of the mercury-containing garbage from the incineration detection time of the mercury-containing garbage specified in S31. In this case, the detection of the incineration of the mercury-containing refuse and the delay in the arrival of the combustion position may be formulated in advance. For example, when the incineration of the mercury-containing refuse is detected after 3 minutes after the mercury-containing refuse reaches the combustion position, the combustion position arrival time may be set to a time 3 minutes before the incineration detection time. After the combustion position arrival time is calculated, the driver can be identified by the processing of S33 described above.

In the example of fig. 9, the process of S32 may be performed after S31, and the process of S32 may be performed first. In this case, the arrival time prediction unit 404 may specify the input time for the garbage input into the hopper 22 during the target period and calculate the time at which the garbage input at each input time arrives at the combustion position. The target period is a period before the time when the incineration of the mercury-containing garbage is detected, and may include a period during which at least one input is performed.

(embodiment mode 2)

In the above embodiment, an example of specifying the operator of the mercury-containing garbage is described, and in the present embodiment, an example of specifying the carrying-in timing of the mercury-containing garbage into pit 21 is described based on fig. 10. Fig. 10 is a block diagram showing an example of the configuration of a main part of the information processing apparatus 4A according to the present embodiment. In fig. 10, the same components as those of the information processing device 4 (the input unit 42 and the like) among the components of the information processing device 4A are not shown.

The control unit 40A includes an entry monitoring unit 401A, a movement monitoring unit 402A, a drop monitoring unit 403A, an arrival time predicting unit 404A, a detecting unit 405, and an entry time determining unit 406A. The storage unit 41A stores garbage position information 411A and input garbage information 412A.

The loading monitoring unit 401A detects loading of the refuse into the refuse incineration facility 100 and specifies the loading time of the refuse. The case where the refuse is carried in may be detected based on the notification from the carrier recognition device 12 as in embodiment 1, or may be detected by a method such as disposing a sensor at the carry-in port 24.

The movement monitoring unit 402A and the input monitoring unit 403A are the same as the movement monitoring unit 402 and the input monitoring unit 403 except that data to be updated is the position information 411A and the input garbage information 412A, respectively.

The garbage position information 411A is information indicating the position of the garbage carried in at each carrying-in time in the pit 21. For example, information obtained by changing "the carrier" to "the carrying-in time" in the garbage position information 411 in fig. 3 (c) may be used as the garbage position information 411A.

The input garbage information 412A is information recorded on garbage input into the hopper 22, similarly to the input garbage information 412. For example, the input garbage information 412A may be information obtained by changing the "input garbage configuration ratio of each carrier" to the "input garbage configuration ratio at the time of input" in the input garbage information 412 of fig. 4.

The arrival time prediction unit 404A calculates the combustion position arrival time of the refuse put into the hopper 22. More specifically, the arrival time prediction unit 404A calculates the combustion position arrival time of the refuse loaded at a plurality of different times, in accordance with the loading time. The carrying-in time specifying unit 406A specifies the carrying-in time of the material that is not suitable for incineration based on the time at which the material that is not suitable for incineration is detected and the combustion position arrival time calculated by the arrival time predicting unit 404A.

If the time of carrying in the material that is not suitable for incineration can be determined, the carrier who carries in the refuse at that time can also be determined. Therefore, the information processing device 4A can also identify the carrier of the material that is not suitable for incineration. The above-mentioned substances unsuitable for incineration may be mercury-containing refuse or other substances unsuitable for incineration.

Further, the function of the carry-in time specification unit 406A may be added to the carry-in person specification unit 406 of the information processing device 4. In this case, the garbage location information 411 records the time of loading of garbage in addition to the garbage loader. The input garbage information 412 may be changed from "the input garbage composition ratio of each carrier" in fig. 4 to "the input garbage composition ratio according to the carrier and the carrying-in time". Then, the arrival time prediction unit 404 calculates the combustion position arrival time of the refuse loaded by a plurality of different loaders at a plurality of different times, for each combination of the loader and the loading time. Thus, the carrier specifying unit 406 can specify the carrier and the carrier time of the material that is not suitable for incineration based on the time at which the material that is not suitable for incineration is detected in the incinerator and the arrival time calculated by the arrival time predicting unit 404. According to this configuration, not only the person who carries the material that is not suitable for combustion but also the time of carrying can be specified, and therefore the user of information processing device 4 can be made to recognize the carrying situation of the material that is not suitable for combustion in more detail.

(modification example)

Modifications of the above embodiments will be described below. Note that, although a modification of the information processing apparatus 4 will be mainly described below, the modification of the information processing apparatus 4 can be applied to the information processing apparatus 4A unless otherwise specified. When the modified example of the information processing apparatus 4 is applied to the information processing apparatus 4A, "the carrier" in the following description may be replaced with "the carrying-in time" as appropriate.

The execution body of each process described in each of the above embodiments can be appropriately changed. For example, it is possible to cause another apparatus other than the information processing apparatus 4 to execute the process of updating the trash position information 411. In this case, the entry monitoring unit 401 and the movement monitoring unit 402 can be omitted from the information processing device 4. For example, the input monitoring unit 403 may be omitted from the information processing apparatus 4, and the other apparatuses may monitor the input and update the input garbage information 412. Similarly, the detection unit 405 may be omitted from the information processing device 4, and another device may detect a substance that is not suitable for combustion.

The identification of the carrier can be performed in the same manner as in the information processing device 4, as long as a system is configured with a device including the arrival time prediction unit 404 and a device including the carrier identification unit 406. That is, the main body of execution of the arrival time prediction step and the main body of execution of the carry-in person specification step included in the information processing methods in the above-described embodiments may be one information processing apparatus or may be different information processing apparatuses.

In embodiment 1, an example is shown in which the transporter specifying unit 406 specifies one transporter based on the input refuse configuration ratio of each transporter, but a plurality of transporters may be specified. For example, since there is a possibility that a carrier who has an input refuse configuration ratio larger than 0 is a carrier who is not suitable for incineration, the carrier specifying unit 406 can specify all carriers who have an input refuse configuration ratio larger than 0. The carrier specifying unit 406 may specify, for example, all carriers having a ratio of the charged garbage to a predetermined value or more as carriers of substances unsuitable for incineration. The same applies to the entry time in embodiment 2.

The carrier specifying unit 406 may specify a carrier who is determined to be a material unsuitable for incineration a plurality of times as a condition, and specify the carrier as a carrier of a material unsuitable for incineration. This reduces the risk of a person who is not a material not suitable for incineration erroneously determining that the person is a material not suitable for incineration.

However, there is a possibility that liquid mercury may leak from the mercury-containing garbage. Therefore, the transporter specifying unit 406 may specify a transporter of the refuse located at the upper layer among the refuse whose mercury is detected in the pit 21 as a post-compensation of the transporter of the mercury-containing refuse. Thereby, the true transporter of the mercury-containing waste can be identified even in the following cases: mercury leaks from garbage carried in by a mercury-containing garbage carrier, and infiltrates into other garbage, and mercury is detected when the other garbage is incinerated. In this case, it is sufficient to record not only the latest trash position but also a trash position history after the trash position is thrown into the pit 21 in the trash position information 411.

The result of the determination by the carrier of the material not suitable for incineration can be output from the output unit 43 and used for various purposes. For example, when it is detected that the carrier who is determined by the carrier determination unit 406 to be a carrier who is not suitable for incineration carries the refuse into the refuse incineration facility 100 again, the carry-in monitoring unit 401 may notify the pre-refuse-collection measuring device 1 of the fact. This enables a person in charge of the measurement facility 1 before refuse reception to confirm before the refuse is thrown into the pit 21. The carry-in monitoring unit 401 may determine whether or not a material unsuitable for combustion is included by imaging the refuse carried in by the carrier identified as a material unsuitable for combustion by the carrier identifying unit 406 using an imaging device disposed at the carry-in port 24 or the like, and analyzing the imaged image.

Further, when it is detected that the carrier who is determined by the carrier determining unit 406 to be a carrier who is not suitable for incineration of the refuse is again carried into the refuse incineration facility 100, the carrying-in monitoring unit 401 may monitor the refuse until the refuse is incinerated. Further, the carrying-in monitoring unit 401 may change the incineration conditions of the refuse so as not to generate harmful substances or suppress the amount of the generated harmful substances via the incinerator control device 7 while the refuse is present in the combustion chamber 31. For example, if a person who has carried in substances unsuitable for combustion, which have generated a large amount of harmful substances at high temperatures, in the past, may change the incineration conditions to an incineration temperature at which the harmful substances are difficult to generate.
