(Embodiment)
(Network configuration of transaction management system 1)
FIG. 1 is an explanatory diagram showing a network configuration of a transaction management system 1 according to an embodiment. As shown in FIG. 1, the transaction management system 1 includes a transaction management server 100, a factory terminal device 110, and a user terminal device 120. Each device is communicably connected by a network 140 (eg, a TCP/IP network, a mobile network, etc.). Further, each device is a computer device including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a communication section, and the like.

(Transaction management server 100)
Transaction management server 100 is an example of a transaction management device. The transaction management server 100 manages transactions of valuable metals between a user who is a collection business and a recycling factory (recycling processor) such as a smelter. In a transaction, a user delivers recycled raw materials (scrap) to a recycling factory. Recycled raw materials may be brought directly to the recycling factory by the user, or may be brought to the recycling factory via a third party.

Recycled raw materials contain valuable metals. Valuable metals include, for example, gold, silver, copper, and the like. The user receives compensation from the recycling factory based on the valuable metals contained in the recycled raw materials. The value of the valuable metal is determined based on the evaluation result through a valuable metal content evaluation process at the recycling factory. The content evaluation process includes multiple steps such as weight measurement of raw materials, crushing, reduction, sampling, moisture measurement, and analysis of contained metals. Valuable metals are metals that can be expected to be traded. Depending on the evaluation results, recycled raw materials may not contain valuable metals.

The transaction management server 100 includes a transaction management DB (database) 101 (an example of a registration means), and manages transaction information for each user based on the contents stored in the transaction management DB 101. The transaction information includes various schedules such as the scheduled date and amount of recycled materials to be brought to the recycling factory, as well as evaluation results in the content evaluation process. Note that details of the transaction management DB 101 will be described later using FIG. 4A, FIG. 4B, and FIG. 4C.

(Factory terminal device 110)
The factory terminal device 110 is placed in the work area of each process in the recycling factory. That is, the number of factory terminal devices 110 exists in accordance with the work area. The factory terminal device 110 is, for example, a computer device such as a personal computer, a smartphone, or a tablet terminal. The factory terminal device 110 receives various operations from work staff (factory staff) in each process related to a transaction.

For example, the factory terminal device 110 accepts input operations indicating the start of each process, various input operations in each process, input operations for LOT numbers assigned to each raw material, and the like. The LOT number is identification information attached to each recycled raw material delivered to a recycling factory. The LOT number is represented by, for example, a raw material identification code such as a QR code (registered trademark). The raw material identification code is attached to the recycled raw material and is read by a reader such as a scanner or a camera. The work staff performs an operation to read the raw material identification code using a reader. Thereby, the factory terminal device 110 can acquire the raw material identification code.

The factory terminal device 110 transmits input information received in response to operations by work staff to the transaction management server 100. The transaction management server 100 registers input information received from the factory terminal device 110 in the transaction management DB 101.

(Example of transaction information stored in transaction management DB 101)
FIG. 4A, FIG. 4B, and FIG. 4C are explanatory diagrams showing examples of transaction information stored in the transaction management DB 101. Although FIG. 4A, FIG. 4B, and FIG. 4C will be explained in three separate figures due to the paper size, they can be represented in one figure. Transaction management DB 101 is realized by memory 202.

4A, 4B, and 4C, the transaction management DB 101 stores information such as "user name", "user ID", "LOT", "shipping guide number", "shipping date", and "delivery schedule". ``date'', ``receiving place'', ``accepting date'', ``status'', ``raw material image'', ``estimated/confirmed'', ``sampling'', ``sampling video'', and ``wet amount''. , "moisture", "dry weight", and "components". Each item is input based on the operation of the factory terminal device 110 by the work staff or the operation of the user terminal device 120 by the user. By inputting predetermined information into each item, transaction information 401 is stored for each transaction in the transaction management DB 101.

Each item of the transaction management DB 101 will be explained below.
The "user name" is the user's name (for example, company name, branch name, office name, etc.).
The "user ID" is identification information that can uniquely identify a user who is a collection business.
“LOT” is identification information that identifies transactions related to recycled materials brought in by users. “LOT” is attached to each transaction. Therefore, if the same type of recycled materials is brought in in multiple containers, the same LOT will be assigned to the recycled materials in multiple containers, whereas if the same type of recycled materials is brought in in one container, A LOT is attached to the valuable recycling of containers.

"Shipping guide number" is an identification number that identifies a shipping guide issued before shipping. The shipping guide is a document or electronic data that describes the details of the received reservation and requests such as the shipping method based on the reservation related to the transaction of recycled raw materials.
The "shipping date" is the date on which the user ships the recycled materials.
The "scheduled delivery date" is the scheduled date on which the user will bring the recycled materials to the recycling factory.
The "acceptance site" is a smelter (recycling factory) that accepts recycled raw materials.
The "acceptance date" is the date on which the recycling factory receives the recycled materials.
“Status” indicates a process related to trading of recycled materials. For example, there are 15 types of "status", and the illustration shows 15 types of status for convenience of explanation. Details of the "status" will be described later.
"Estimated/confirmed" indicates information on recycled materials brought in by the user, and indicates "estimated" inputted by the user at the time of reservation, and "confirmed" inputted by the work staff in the content evaluation process.
The "raw material image" is imaged data of recycled materials received by a recycling factory, and is, for example, imaged data taken by a work staff at the start of weighing.

"Sampling" indicates a sampling method. "Sampling" includes, for example, automatic sampling and manual sampling.
When sampling a portion of recycled raw materials for the evaluation process, automatic sampling uses a machine, and manual sampling uses a shovel or the like to be carried out by work staff. In manual sampling, work staff samples arbitrary parts, whereas in autosampling, a machine automatically samples randomly. Automatic sampling may not be possible in some cases, such as when the sample contains large members that are difficult to crush mechanically, and in this case manual sampling is selected.
"Sampling" includes "probable" sampling and "determined" sampling. “Prospective” sampling is a sampling method desired by the user. “Confirmed” sampling is a sampling method determined by the recycling plant. “Prospective” sampling may be different from “determined” sampling.

For example, although the user desires autosampling, manual sampling may be more appropriate than autosampling. A case where manual sampling is more appropriate is, for example, a case where there is a large amount of metal, or in other words, a case where the crusher may be damaged. In such a case, the sampling method is changed by obtaining the user's consent. Although the illustration shows two types of sampling methods, the sampling method is not limited to two types, and may be three or more types. For example, autosampling sampling methods include high-quality sampling that combines two-stage crushing and reduction with eddy current separation between the two crushings, large-lot sampling using four-axis crushing, and single-shaft crushing. A plurality of sampling methods may be included, such as sampling using a Snyder sampler.

The "sampling video" is imaged data at the time of sampling, which is imaged by the work staff in the sampling process.

"Wet weight" indicates the weight of the recycled material including moisture. The "wet amount" includes an "estimated" wet amount and a "determined" wet amount. The "expected" moisture amount is the moisture amount input by the user. The “determined” sampling is the actual wet amount (evaluation result) measured by the work staff. In the status where the measurement of the wet weight is not completed (the status of "waiting for arrival" and the status of "measured/inspecting"), the wet weight of "confirmed" in the transaction information 401 indicates "NULL".
"Moisture" indicates the amount of water (evaluation result) contained in the recycled raw material. In a status where the measurement of the moisture content is not completed (a status up to "moisture value measurement in progress"), the moisture content of "confirmed" in the transaction information 401 indicates "NULL".

"Dry weight" indicates the weight (evaluation result) of the recycled raw material after drying. In a status where the moisture content measurement has not been completed (a status up to “moisture value measurement in progress”), the dry amount of “confirmed” in the transaction information 401 indicates “NULL”.
"Component" is a component (evaluation result) indicating each metal contained in the recycled raw material, such as gold, silver, copper, etc. In a status where the analysis of the component has not been completed (a status up to "under analysis"), the "confirmed" component of the transaction information 401 indicates "NULL".

(About status)
The 15 types of status will be explained below.
(1) "Waiting for arrival": Indicates the period from the time of reservation until the recycled materials are delivered to the receiving location.
(2) "Arrived/waiting for weighing": Indicates that the recycled materials have been delivered to the receiving location, unloaded, the receiving has been completed, and preparations are being made for weighing. When recycled raw materials are brought in, a QR code (raw material identification code) indicating transaction (recycled raw material) identification information (for example, LOT) is attached. The factory terminal device 110 can read the raw material identification code and input the LOT number in accordance with the operation of the work staff in each process. Furthermore, the input information in each step is associated with the LOT number and transmitted to the transaction management server 100. Note that the raw material identification code may be any information that can identify the recycled raw material, and may be information other than the LOT number.
(3) "Weighed/Inspecting": Indicates that the weighing of recycled materials (including wet weight) has been completed and is being inspected at the sampling yard.
(4) "Sampling": Indicates that the recycled raw material is being sampled.
(5) "Measuring moisture value": Indicates that sampling of the recycled raw material has been completed and the moisture value is being measured.
(6) "Analyzing": Indicates that the measurement of the moisture value of the recycled raw material has been completed and the contained metal is being analyzed.
(7) “Analysis value confirmed”: Indicates that the analysis has been completed and the analysis value has been confirmed.
(8) “Reanalysis value confirmed”: Indicates that the reanalysis has been completed and the reanalysis value has been determined.
(9) “Re-re-analysis value confirmed”: Indicates that re-analysis has been completed and re-analysis value has been determined.
(10) “Acceptance canceled”: Indicates that acceptance was canceled after the month of acceptance.
(11) “Estimated payment”: Indicates completion of estimated payment.

Updates to (11) to (14) above: Input indicating each payment.
Update to (15) above: Input indicating acceptance.

(An example of a reservation screen related to trading of recycled materials)
Next, the reservation screen displayed on the user terminal device 120 will be described using FIG. 5.
FIG. 5 is an explanatory diagram showing an example of a reservation screen displayed on the user terminal device 120. In FIG. 5, a reservation screen 500 is a screen that is displayed when a reservation start button displayed on a home screen (not shown) is pressed (selected). The reservation screen 500 accepts various inputs from the user.

Specifically, the reservation screen 500 includes various input fields. More specifically, the reservation screen 500 includes a basic information input field 510 and a lot information input field 520. The basic information input field 510 includes "Shipping date", "Scheduled delivery date", "Receiving location", "Raw material group", "Transportation means", "Transportation company", "Vehicle number", "Driver", " Includes columns for ``Quantity'' and ``Remarks''. In each column, for example, letters and numbers may be input from a pull-down menu, or letters and numbers may be input directly.

The "shipment date" column accepts the user's designation of the date on which recycled materials are to be shipped. The "scheduled date for bringing in" column accepts the user's designation of the scheduled date for bringing in the recycled materials. The "Acceptance Place" column accepts the designation of the smelter (factory) that will receive the recycled raw materials. The "Raw Material Group" column accepts the designation of recycled raw materials or precious metal raw materials that are raw materials for precious metals. In this embodiment, it is assumed that the user specifies recycled raw materials. The "transportation means" column accepts, for example, the designation of a business office that handles transportation of recycled materials. The "transport company", "vehicle number", "driver", and "number of vehicles" columns accept input of various information regarding the transportation of recycled materials.

The lot information input field 520 includes "product name", "packing style", and expected information 521. The "product name" column accepts product names such as gold and silver slag, parts, uncrushed substrates, and sludge. The "Packaging form" field accepts input of the type of container in which recycled materials are packed and the number of containers.

The prospect information 521 is information indicating the prospect related to the transaction specified by the user. Specifically, the expected information 521 indicates information input in each column of desired sampling 521a, wet amount 521b, and quality 521c. The column of desired sampling 521a accepts the sampling method desired by the user. Specifically, the desired sampling column 521a accepts any one of automatic sampling, manual sampling, and no designation, for example.

The wet weight column 521b accepts an input of the expected weight including moisture predicted by the user regarding the weight of the recycled raw material.
The column of quality 521c accepts input of the expected content rate (or content) of each component contained in the recycled raw material.

On the reservation screen 500, when items are entered in various input fields and the confirmation button 530 is pressed, the screen changes to a confirmation screen (not shown). When confirmation of the reservation details is accepted on the confirmation screen, the reservation details are confirmed. When the reservation details are confirmed, the user terminal device 120 transmits transaction information indicating the confirmed reservation details to the transaction management server 100. The transaction management server 100 then registers the transaction information in the transaction management DB 101.

(Example of functional configuration of transaction management system 1)
Next, the functional configuration of the transaction management system 1 will be explained.
FIG. 6 is a block diagram showing an example of the functional configuration of the transaction management system 1. In FIG. 6, the transaction management server 100 includes an input information acquisition section 601, an update section 602, a transmission section 603, an extraction section 604, and a prospective information acquisition section 605. Each part is realized by the CPU 201 included in the transaction management server 100. That is, the CPU 201 executes the transaction management program stored in the memory 202 to realize the functions of each part.

Further, the user terminal device 120 includes a requesting section 611, a receiving section 612, and a display control section 613. Each part is realized by the CPU 301 included in the user terminal device 120. That is, the CPU 301 executes the display control program stored in the memory 302 to realize the functions of each part.

The input information acquisition unit 601 is an example of an information acquisition means. The input information acquisition unit 601 acquires information on the progress status at each process including the content evaluation process of a transaction related to recycled raw materials. Each process corresponds to each status. The progress status information includes, for example, input information received from the work staff at each process. The input information is information based on a specified input related to updating the status. The input information includes the evaluation results in the content evaluation process.

The updating unit 602 updates status information corresponding to each process based on the input information acquired by the input information acquisition unit 601. The status information is information indicating the status among the transaction information registered in the transaction management DB 101. To give an example of updating the status information, as described above, if the current status is "waiting for arrival", the updating unit 602 acquires input information indicating that the recycled material has been delivered to the receiving location. By doing so, the status is updated to "arrived/waiting for weighing".

(Display of viewing screen by user terminal device 120)
The user terminal device 120 can display a viewing screen based on screen information including transaction information. The request unit 611 of the user terminal device 120 requests the transaction management server 100 to view screen information. The requesting unit 611 issues a viewing request by accepting an instruction to start displaying the viewing screen from the user. The viewing request includes a user ID that identifies the user.

The transmission unit 603 of the transaction management server 100 transmits screen information to the user terminal device 120 in response to a viewing request from the request unit 611. The transmitted screen information includes all transaction information related to the transactions of the user. In other words, the transmitted screen information does not include transaction information related to transactions of other users other than the user.

When transmitting the screen information related to the user's transaction, the corresponding transaction information is extracted. Specifically, the extraction unit 604 extracts transaction information corresponding to the user ID, based on the user ID included in the viewing request. The transmitter 603 transmits screen information including only the transaction information extracted by the extractor 604 to the user terminal device 120.

Note that the screen information to be transmitted may also be specific transaction information designated by the user among all transaction information related to the user's transactions. In this case, the viewing request only needs to include the LOT number in order to identify the transaction information. The extraction unit 604 may extract transaction information including the LOT number based on the LOT number included in the viewing request.

Further, the transmitter 603 transmits screen information not only to the user terminal device 120 but also to the factory terminal device 110. Specifically, the transmitter 603 transmits screen information indicating transaction information to the factory terminal device 110. The screen information transmitted to the factory terminal device 110 includes transaction information related to all transactions, that is, includes transaction information that is not extracted by the extraction unit 604. The timing for transmitting the screen information to the factory terminal device 110 may be the timing when a viewing request is received from the factory terminal device 110, the lapse of a predetermined time (sequentially), or the timing when a new reservation is made from the user terminal device 120. It may also be the timing of acceptance.

The receiving unit 612 receives screen information from the transaction management server 100 in response to the viewing request from the requesting unit 611. The display control unit 613 displays the screen information received by the receiving unit 612 on a display (display unit). Thereby, the user terminal device 120 can display the status in the content evaluation process. Examples of screens displayed by the display control unit 613 will be described later using FIGS. 9 to 11.

(About updating status based on input of evaluation results)
The steps in the content evaluation process include an evaluation step related to evaluation of recycled raw materials. The evaluation step includes, for example, a step of weighing recycled raw materials, a step of measuring a moisture value, and a step of analyzing component values. The input information acquisition unit 601 acquires the evaluation results received in the evaluation process as input information. The evaluation results are, for example, moisture content, moisture content, and components.

The update unit 602 updates the status information in response to the input information acquisition unit 601 acquiring the evaluation results. As described above, for example, if the current status is "measuring moisture value", the updating unit 602 updates the status to "under analysis" when the moisture value is input as input information.

(About sending evaluation results)
The screen information transmitted by the transmitter 603 includes the evaluation results. That is, the transmitter 603 transmits screen information including the evaluation results to the user terminal device 120 in response to a viewing request from the user terminal device 120. The user terminal device 120 displays screen information including the evaluation results. This allows the user to check the evaluation results.

(About notification when there is a discrepancy between expected information and input information)
The prospective information acquisition unit 605 acquires prospective information 521 (see FIG. 5). The transmitter 603 transmits a confirmation notification to the user terminal device 120 based on the discrepancy between the prospective information 521 and the input information. Specifically, as described above, the expected information 521 includes the sampling method desired by the user, the expected weight (wet weight) of the recycled raw material specified by the user, and the components. It also includes the measurement results in the process of weighing recycled raw materials.

The transmitter 603 transmits a confirmation notification to the user terminal device 120 based on the discrepancy between the estimated weight and the weighing result. For example, the transmitting unit 603 transmits a confirmation notification to the user terminal device 120 when there is a discrepancy between the estimated weight and the weighing result by a predetermined discrepancy rate (for example, 5%) or more. On the other hand, the transmitter 603 does not transmit the confirmation notification to the user terminal device 120 if there is no deviation between the estimated weight and the weighing result by a predetermined deviation rate (5%) or more. The confirmation notification is sent based on the operation of the work staff, but it may be sent automatically.

Here, with reference to FIG. 7, a viewing screen showing that a confirmation notification regarding weight has been issued will be described.
FIG. 7 is an explanatory diagram illustrating an example of a viewing screen indicating that a confirmation notification regarding weight has been issued. In FIG. 7, the viewing screen 700 includes a weight information field 710, a person in charge field 720, and an imaging data area 730. The weight information column 710 includes the expected moisture content input by the user, the measured moisture content measured by the work staff, the deviation rate, and the like.

If the deviation rate is 5% or more, the factory terminal device 110 accepts a specified operation from the work staff member related to a confirmation notification (e.g., sending an email) addressed to the user. When the factory terminal device 110 accepts a specified operation from the work staff member, it sends a confirmation notification to the user terminal device 120. On the viewing screen 700, the name of the work staff member who sent the confirmation notification (○○ Ichiro ○○ Smelter Operations Department) is displayed as a registered person.

Upon receiving the confirmation notification, the user terminal device 120 accepts approval or rejection from the user regarding the deviation. The screen for accepting acceptance or rejection may be on the viewing screen 700, or may be on another screen (for example, an email screen). A viewing screen 700 shows a screen on which consent is received from the user regarding the deviation. Specifically, in the person in charge column 720, the name of the user who approved the change (Saburo ○○: A Corporation) is displayed in the confirmer and updater columns. Note that when the user terminal device 120 receives a refusal from the user regarding the deviation, it may further accept a request to cancel the transaction. Further, a request for re-analysis may be accepted from the user, and if there is a discrepancy in the re-analysis, a request for further analysis may be accepted.

(Regarding the imaging data area 730)
In the imaging data area 730, raw material image data 731 is displayed. The raw material image data 731 is an image of the recycled material received by the recycling factory, and shows an image when the weighing of the recycled material is started. The image is taken by the work staff, for example, during the process of waiting for weighing. The device used for taking the image is, for example, a smartphone as the factory terminal device 110. A predetermined application (application software) related to the transaction management system 1 is pre-installed in the smartphone. The work staff starts the application and takes an image of the recycled material. The factory terminal device 110 uploads the raw material image data 731 obtained by taking the image to the transaction management server 100. Such raw material image data 731 can visualize the recycled material received by the recycling factory. Therefore, the user can easily check whether the recycled material shipped to the recycling factory and the recycled material actually brought in match with each other by using the raw material image data 731.

(For other examples of confirmation notices)
In this embodiment, the confirmation notification is sent not only when the deviation rate is 5% or more, but also when the sampling method is changed. This will be explained. As described above, the prospect information 521 includes information indicating one sampling method specified by the user among a plurality of sampling methods used in the sampling process. The input information also includes information indicating the sampling method specified by the work staff. The sampling method specified by the work staff may be different from the one sampling method specified by the user. That is, the input information may include information indicating another sampling method different from the one sampling method specified by the user.

The transmitter 603 transmits a confirmation notification based on one sampling method and another sampling method to the user terminal. Specifically, the transmitter 603 transmits a confirmation notification to the user terminal device 120 when there is a discrepancy between the two sampling methods. On the other hand, the transmitter 603 does not transmit the confirmation notification to the user terminal device 120 when there is no discrepancy between the two sampling methods. The confirmation notification is sent based on the operation of the work staff, but it may be sent automatically.

Here, with reference to FIG. 8, a viewing screen indicating that a confirmation notification regarding a change in the sampling method has been sent will be described.
FIG. 8 is an explanatory diagram illustrating an example of a viewing screen indicating that a confirmation notification regarding a change in the sampling method has been sent. In FIG. 8, the viewing screen 800 includes a sampling information field 810, a person in charge field 820, and an imaging data area 830. The sampling information column 810 includes the desired sampling method specified by the user, the sampling method related to the change specified by the work staff, the reason for the change, and the like.

When changing the sampling method, the factory terminal device 110 receives a predetermined operation related to a confirmation notification (for example, sending an email) to the user from the work staff. Upon receiving a predetermined operation from the work staff, the factory terminal device 110 transmits a confirmation notification to the user terminal device 120. On the viewing screen 800, the name of the work staff who sent the confirmation notice (Taro XXX Smelter Business Division) is displayed as a registrant.

When the user terminal device 120 receives the confirmation notification, it accepts or rejects the change in sampling method from the user. The screen for accepting the acceptance or rejection may be on the viewing screen 800 or another screen (e.g., an email screen). The viewing screen 800 shows the screen on which the acceptance of the change in sampling method from the user is accepted. Specifically, the person in charge column 820 displays the name of the user who accepted the change (○○ Jiro: A Co., Ltd.) in the checker and updater columns. Note that if the user terminal device 120 accepts a rejection of the change in sampling method from the user, it may further accept a cancellation of the transaction.

(About sampling video 831)
In this embodiment, the step (evaluation step) of the content evaluation process includes a step in which the recycled raw material is imaged by the work staff. The process in which imaging is performed is, for example, a sampling process. The imaging data is, for example, a moving image (sampled moving image). Note that the process in which imaging is performed is not limited to the sampling process, and may be other processes.

The transmitter 603 transmits screen information including captured data to the user terminal device 120 in response to a viewing request from the user terminal device 120 . User terminal device 120 displays a viewing screen 800 that includes imaging data. Specifically, raw material image data 731 and a sampling moving image 831 are attached to the imaging data area 830. The sampling video 831 is shot by the work staff in charge of the sampling process.

The device used for photographing is, for example, a smartphone serving as the factory terminal device 110. A predetermined application (application software) related to the transaction management system 1 is installed in the smartphone in advance. The work staff starts the application and shoots a video of the sampling process. The factory terminal device 110 uploads the sampled video 831 obtained by shooting to the transaction management server 100. Such a sampling video 831 makes it possible to visualize the sampling process (sampling method, sampling execution). Therefore, the user can easily confirm the sampling process related to the transaction.

(Transaction list viewing screen displayed on user terminal device 120)
FIG. 9 is an explanatory diagram showing an example of a transaction list viewing screen displayed on the user terminal device 120. In FIG. 9, a list 900 related to user transactions is displayed on the display of the user terminal device 120. The list 900 includes detailed information such as a status 901a and a shipping guide number 901b for each transaction 901. The list list 900 also includes a left and right scroll bar 910a and a top and bottom scroll bar 910b.

The user can also view items other than the items displayed on the screen by moving the left and right scroll bar 910a to the right. Furthermore, by moving the vertical scroll bar 910b downward, the user can view transactions 901 in other statuses that are not displayed on the screen.

Note that the list list 900 can also be displayed on the factory terminal device 110. The factory terminal device 110 can display a screen similar to the list list 900 by narrowing down the users. Note that if the filtering is not performed, the factory terminal device 110 can display a list of transactions 901 of all users.

(Other screen examples of transaction list viewing screen)
Next, another screen example of the transaction list viewing screen will be explained. In the list list 900 shown in FIG. 9, the display format of the list list 900 can be changed by operating a predetermined button that accepts screen switching. Examples of screens with different display formats will be explained using FIG. 10.

FIG. 10 is an explanatory diagram showing another screen example of the transaction list viewing screen. In FIG. 10, a group list 1000 of each transaction is displayed on the display of the user terminal device 120. The group list 1000 is a screen that displays each status classified into three groups. The groups are displayed divided into three groups, for example, an uncompleted acceptance group 1010, a group under analysis 1020, and a group after analysis confirmed 1030.

The uncompleted acceptance group 1010 shows transaction information of each status: "Waiting for arrival,""Arrived/Waiting for measurement," and "Weighed/Inspecting."
The under analysis group 1020 shows transaction information of each status: "under sampling", "under moisture value measurement", and "under analysis".
The post-analysis group 1030 includes “Analysis value confirmed,” “Re-analysis value confirmed,” “Re-analysis value confirmed,” “Estimated payment,” “Settlement payment,” “Re-payment,” “Re-re-payment,” and Shows transaction information for each status of “Consignment”.

The group list 1000 also includes a scroll bar 1050. By moving the scroll bar 1050 downward, the user can view other transactions 1001 that are not displayed on the screen for each group 1010, 1020, 1030.

In the group list 1000, each transaction 1001 includes items such as a shipping guide number 1002, a status 1003, a product name 1004, and a scheduled delivery date 1005. Therefore, compared to the transaction 901 shown in the list list 900, the transaction 1001 displayed in the group list 1000 has fewer items displayed.

The group list 1000 also includes group displays 1040a, 1040b, and 1040c. Group displays 1040a, 1040b, and 1040c indicate status, and are displayed in different display modes (for example, different colors) for each group. Furthermore, the status displays 1003a, 1003b, and 1003c are displayed in the same display manner (eg, the same color) in correspondence with the group displays 1040a, 1040b, and 1040c. Specifically, the group display 1040a and the status display 1003a are displayed in the same color. Group display 1040b and status display 1003b are displayed in the same color. Group display 1040c and status display 1003c are displayed in the same color.

In this way, in the group list 1000, the status is displayed separately for each group, so the approximate status can be easily grasped. Furthermore, since the user can recognize each group 1010, 1020, and 1030 by color, the user can more easily grasp the approximate status. Note that the user terminal device 120 can switch from the group list 1000 to the list list 900 by accepting a predetermined operation in the group list 1000.

Further, the factory terminal device 110 can also display a list list or a group list, similarly to the user terminal device 120. Further, the factory terminal device 110 can also switch from a list list to a group list or from a group list to a list list by operating a predetermined button that accepts screen switching.

(Details viewing screen displayed on user terminal device 120)
Next, a detailed viewing screen displayed on the user terminal device 120 will be described. When a predetermined button (for example, shipping guide number 901b, 1002 corresponding to a transaction) is pressed in the list list 900 shown in FIG. 9 or the group list 1000 shown in FIG. Transition. The details viewing screen will be explained using FIG. 11. In addition, in FIG. 11, a detailed viewing screen for a transaction with a status of "analysis value confirmed" will be explained.

FIG. 11 is an explanatory diagram showing an example of a detailed viewing screen displayed on the user terminal device 120. In FIG. 11, a detailed viewing screen 1100 includes lot information 1110. The lot information 1110 includes the following items: "Product Name", "Acceptance Date", "LOT", "Status", "Wet Weight", "Moisture", "Dry Weight", "Component", and "Sampling". "Wet amount", "component", and "sampling" include the expected information 521 input on the reservation screen 500 (see FIG. 5) and the evaluation results input at the recycling factory.

Such a detailed viewing screen 1100 allows the user to understand evaluation results and the like in detail for each transaction with a simple operation.

(About the processing flow in transaction management system 1)
Next, the flow of processing in the transaction management system 1 will be explained using FIG. 12.
FIG. 12 is a sequence diagram showing the flow of processing in the transaction management system 1. In FIG. 12, the user terminal device 120 receives transaction reservation registration from the user (step S1201). Upon receiving the reservation registration, the user terminal device 120 transmits the received reservation details to the transaction management server 100.

Upon receiving the reservation details from the user terminal device 120, the transaction management server 100 registers the received reservation details as transaction information in the transaction management DB 101 (step S1202). The transaction management server 100 then transmits the transaction information to the factory terminal device 110.

Upon receiving the transaction information from the transaction management server 100, the factory terminal device 110 displays the received transaction information on the display (step S1203). Then, the factory terminal device 110 receives predetermined inputs related to status updates, such as evaluation results, in response to operations by the work staff (step S1204). Upon receiving a predetermined input, the factory terminal device 110 transmits input information corresponding to the received input to the transaction management server 100.

Upon receiving the input information from the factory terminal device 110, the transaction management server 100 updates the transaction information based on the input information (step S1205). Updating transaction information includes updating status. Note that the processing in steps S1204 and S1205 is repeated every time there is a predetermined input from the work staff.

When the user terminal device 120 receives an operation to start viewing the viewing screen from the user, it issues a viewing request to the transaction management server 100 (step S1206). When the transaction management server 100 receives the viewing request from the user terminal device 120, it extracts the transaction information of the user based on the user ID included in the viewing request (step S1207). Then, the transaction management server 100 transmits screen information including only the extracted transaction information to the user terminal device 120. The user terminal device 120 displays a list of viewing screens including its own (company's) transaction information received from the transaction management server 100 on the display (step S1208).

Further, upon receiving an operation to start viewing the viewing screen from the work staff, the factory terminal device 110 issues a viewing request to the transaction management server 100 (step S1209). Note that the request to start viewing may be automatically made at regular timing when the factory terminal device 110 is started. Upon receiving the viewing request from the factory terminal device 110, the transaction management server 100 transmits all screen information to the user terminal device 120. The user terminal device 120 displays a list of viewing screens including all transaction information received from the transaction management server 100 on the display (step S1210). Note that the factory terminal device 110 is capable of displaying a viewing screen that includes only transaction information of a specific user from a list display of all transaction information using a filtering function.

Next, the processing performed by the user terminal device 120 and the processing performed by the transaction management server 100 will be explained respectively. First, the processing performed by the user terminal device 120 will be explained.

(Example of processing performed by user terminal device 120)
FIG. 13 is a flowchart illustrating an example of processing performed by the user terminal device 120. Note that the process shown in FIG. 13 is a process that is always started (regularly at very short time intervals) in the user terminal device 120. In FIG. 13, the user terminal device 120 determines whether an operation to start a new reservation registration related to a transaction has been received (step S1301). If the operation to start new reservation registration is not accepted (step S1301: NO), the user terminal device 120 proceeds to the process of step S1304.

If an operation to start new reservation registration is accepted (step S1301: YES), the user terminal device 120 accepts input of various reservation details (step S1302). When the reservation details are confirmed, the user terminal device 120 transmits transaction information indicating the reservation details to the transaction management server 100 (step S1303).

Next, the user terminal device 120 determines whether an operation to start viewing has been accepted (step S1304). If the operation to start viewing is not accepted (step S1304: NO), the user terminal device 120 ends the series of processing. If the operation to start viewing is accepted (step S1304: YES), the user terminal device 120 transmits a viewing request to the transaction management server 100 (step S1305).

In response to the viewing request, the user terminal device 120 receives screen information containing only its own transaction information from the transaction management server 100 (step S1306). Then, the user terminal device 120 displays a list of screen information including only its own transaction information received from the transaction management server 100 on the display (step S1307). Next, the user terminal device 120 determines whether display switching has been accepted (step S1308). Display switching is, for example, switching to any one of a plurality of screens including list list 900, group list 1000, and detailed viewing screen 1100.

If the display switching is not accepted (step S1308: NO), the user terminal device 120 ends the series of processing. On the other hand, if the display switching is accepted (step S1308: YES), the user terminal device 120 switches the display to the viewing screen according to the accepted operation (step S1309), and ends the series of processing.

(Example of processing related to status update performed by transaction management server 100)
14 and 15 are flowcharts illustrating an example of a process related to status update performed by the transaction management server 100. Note that the processes shown in FIGS. 14 and 15 are processes that are always started (regularly at very short time intervals) in the transaction management server 100. In FIG. 14, the transaction management server 100 determines whether reservation details indicating new reservation registration have been received from the user terminal device 120 (step S1401). If reservation details indicating new reservation registration are not received (step S1401: NO), the transaction management server 100 advances to step S1403.

On the other hand, if reservation details indicating new reservation registration are received (step S1401: YES), the transaction management server 100 registers the reservation details received from the user terminal device 120 in the transaction management DB 101 as transaction information (step S1402). . Then, the transaction management server 100 determines whether the recycled raw materials have arrived (step S1403). Specifically, the determination in step S1403 is made when the factory terminal device 110 receives an input from the work staff indicating that recycled materials have been delivered to the receiving location, and receives input information indicating the input from the factory terminal device 110. It is a judgment of whether or not it was done.

If the recycled raw material has not arrived (step S1403: NO), the transaction management server 100 proceeds to the process of step S1405. On the other hand, if the recycled raw material has arrived (step S1403: YES), the transaction management server 100 updates the status from "waiting for arrival" to "already arrived/waiting for measurement" (step S1404).

Next, the transaction management server 100 determines whether or not raw material image data has been received from the factory terminal device 110 (step S1405). If raw material image data has not been received (step S1405: NO), the transaction management server 100 proceeds to processing of step S1407. On the other hand, if raw material image data has been received (step S1405: YES), the transaction management server 100 registers the raw material image data in the transaction management DB 101 (step S1406). Note that the raw material image data is associated with a LOT number, and is registered in the transaction information indicated by that LOT number.

Next, the transaction management server 100 determines whether there is a discrepancy between the sampling method specified by the user and the sampling method specified by the work staff (step S1407). Note that the determination in step S1407 is not limited to being made by the transaction management server 100, and may be made by the work staff. If there is no discrepancy in the sampling methods (step S1407: NO), the transaction management server 100 proceeds to the process of step S1409.

On the other hand, if there is a discrepancy in the sampling method (step S1407: YES), the transaction management server 100 transmits a confirmation notification (for example, email) to the user terminal device 120 in response to the instruction from the factory terminal device 110 (step S1408 ). In response to receiving information from the user terminal device 120 indicating that the user has consented to the confirmation notification, the transaction management server 100 changes the sampling method. Note that the sampling method may be changed by the factory terminal device 110 receiving a confirmation operation from the work staff instead of or in addition to receiving information indicating that the user has consented from the user terminal device 120. good.

Next, the transaction management server 100 determines whether a wet amount has been input (step S1409). Specifically, the determination in step S1409 is a determination as to whether or not the factory terminal device 110 has received the input information related to the input from the factory terminal device 110 by accepting the input of the wet amount from the work staff. If there is no wet amount input (step S1409: NO), the transaction management server 100 proceeds to the process of step S1411. On the other hand, if the wet amount is input (step S1409: YES), the status is updated from "arrived/waiting for measurement" to "measured/inspecting" (step S1410).

Next, the transaction management server 100 determines whether there is a difference of 5% or more between the input wet weight and the expected weight (step S1411). If there is no difference of 5% or more between the input wet weight and the estimated weight (step S1411: NO), the transaction management server 100 proceeds to the process of step S1413. On the other hand, if there is a discrepancy of 5% or more between the input wet weight and the expected weight (step S1411: YES), the transaction management server 100 sends a message to the user terminal device 120 in response to an instruction from the factory terminal device 110. A confirmation notification (for example, email) is sent (step S1412). When information indicating that the user has consented to the confirmation notification is received from the user terminal device 120, the transaction continues.

Next, the transaction management server 100 determines whether it is time to start sampling (step S1413). Specifically, the determination in step S1413 is made by determining whether or not the factory terminal device 110 has received input information indicating the input from the factory terminal device 110 by accepting an input indicating the start of sampling from the work staff. be.

If it is not the start of sampling (step S1413: NO), the transaction management server 100 proceeds to the process of step S1415. On the other hand, if it is the start of sampling (step S1413: YES), the transaction management server 100 updates the status from "weighed/inspecting" to "sampling" (step S1414).

Next, the transaction management server 100 determines whether the sampling video has been received from the factory terminal device 110 (step S1415). If the sampling video is not received (step S1415: NO), the transaction management server 100 proceeds to the process of step S1417. On the other hand, when the sampling video is received (step S1415: YES), the transaction management server 100 registers the sampling video in the transaction management DB 101 (step S1416). Note that the sampling video is associated with a LOT number, and is registered in the transaction information indicated by the LOT number.

Next, the transaction management server 100 determines whether sampling has ended (step S1417). Specifically, the determination in step S1417 is made by determining whether or not the factory terminal device 110 has received input information indicating the end of sampling from the factory terminal device 110 by accepting an input indicating the end of sampling from the work staff. be.

If sampling has not ended (step S1417: NO), the transaction management server 100 proceeds to processing of step S1419. On the other hand, if sampling has ended (step S1417: YES), the transaction management server 100 updates the status from "Sampling in progress" to "Moisture value measurement in progress" (step S1418).

Next, the transaction management server 100 determines whether a moisture value has been input (step S1419). Specifically, the determination in step S1419 is a determination as to whether or not the factory terminal device 110 has received the input information related to the input from the factory terminal device 110 by accepting the input of the moisture value from the work staff. If there is no moisture value input (step S1419: NO), the transaction management server 100 proceeds to the process of step S1501 in FIG. 15. On the other hand, if a moisture value has been input (step S1419: YES), the status is updated from "moisture value measurement in progress" to "analysis in progress" (step S1420).

Next, the transaction management server 100 determines whether an analysis value has been input (step S1501). Specifically, the determination in step S1501 is a determination as to whether or not the factory terminal device 110 has received the input information related to the input from the factory terminal device 110 by accepting the input of the analysis value from the work staff. If no analysis value is input (step S1501: NO), the transaction management server 100 proceeds to the process of step S1503. On the other hand, if an analysis value has been input (step S1501: YES), the status is updated from "under analysis" to "analysis value confirmed" (step S1502).

Next, the transaction management server 100 determines whether a reanalysis value has been input (step S1503). Specifically, the determination in step S1503 is a determination as to whether the factory terminal device 110 has received input information relating to the input by accepting the reanalysis value from the work staff member. If no reanalysis value has been input (step S1503: NO), the transaction management server 100 proceeds to the processing of step S1505. On the other hand, if a reanalysis value has been input (step S1503: YES), the status is updated from "analysis value confirmed" to "reanalysis value confirmed" (step S1504).

Next, the transaction management server 100 determines whether an analysis value has been input again (step S1505). Specifically, the determination in step S1505 is a determination as to whether or not the factory terminal device 110 has received input information related to the input from the factory terminal device 110 by repeatedly accepting input of analysis values from the work staff. . If no analysis value is input again (step S1505: NO), the transaction management server 100 advances to step S1507. On the other hand, if there is a re-analysis value input (step S1505: YES), the status is updated from "re-analysis value determined" to "re-analysis value determined" (step S1506).

Next, the transaction management server 100 determines whether there is an input to cancel acceptance (step S1507). Specifically, the determination in step S1507 is made when the factory terminal device 110 receives an input of acceptance cancellation from the work staff based on the response to the confirmation notification from the user, and the factory terminal device 110 receives input information related to the input. This is a judgment as to whether or not the message has been received. If there is no input for cancellation of acceptance (step S1507: NO), the transaction management server 100 proceeds to the process of step S1509. On the other hand, if there is an input to cancel acceptance (step S1507: YES), the current status is updated to "cancel acceptance" (step S1508).

Next, the transaction management server 100 determines whether an estimated payment has been input (step S1509). Specifically, the determination in step S1509 is a determination as to whether or not the factory terminal device 110 has received the input information related to the input from the factory terminal device 110 by accepting the input of the estimated payment from the work staff.
The estimated payment is to pay an estimated price based on expected information from the user before the evaluation process is completed.

If there is no input of estimated payment (step S1509: NO), the transaction management server 100 proceeds to the process of step S1511. On the other hand, if there is an input for estimated payment (step S1509: YES), the current status is updated to "estimated payment" (step S1510).

Next, the transaction management server 100 determines whether a settlement payment has been input (step S1511). Specifically, the determination in step S1511 is a determination as to whether or not the factory terminal device 110 has received the input information related to the input from the factory terminal device 110 by accepting the input of the settlement payment from the work staff.
If an estimated payment is made, the settlement payment will be the difference between the consideration calculated from the evaluation results and the estimated payment.

If there is no input of settlement payment (step S1511: NO), the transaction management server 100 proceeds to the process of step S1513. On the other hand, if there is an input for settlement payment (step S1511: YES), the current status is updated to "settlement payment" status (step S1512).

Next, the transaction management server 100 determines whether there is an input for repayment (step S1513). Specifically, the determination in step S1513 is a determination as to whether or not the factory terminal device 110 has received input information related to the input from the factory terminal device 110 by accepting the input of repayment from the work staff.
Repayments are payments made for readjustment when there is a discrepancy between the expected analysis value by the user and the actual analysis value at the recycling factory.

If there is no repayment input (step S1513: NO), the transaction management server 100 proceeds to the process of step S1515. On the other hand, if there is an input for repayment (step S1513: YES), the current status is updated to "repayment" (step S1514).

Next, the transaction management server 100 judges whether or not a third re-payment has been input (step S1515). Specifically, the judgment in step S1515 is a judgment as to whether or not the factory terminal device 110 has received input information relating to the third re-payment from the work staff by accepting the input of the third re-payment from the work staff.
The third payment is a payment that is made for a third adjustment when a discrepancy occurs between the analysis value expected by the user and the actual analysis value at the recycle plant.

If there is no input for repayment (step S1515: NO), the transaction management server 100 advances to step S1517. On the other hand, if there is an input for repeat payment (step S1515: YES), the current status is updated to "repeat payment" (step S1516).

Next, the transaction management server 100 determines whether or not there is an input for acceptance (step S1517). Specifically, the determination in step S1515 is a determination as to whether or not the factory terminal device 110 has received input information related to the input from the factory terminal device 110 by accepting a consignment input from the work staff. If there is no acceptance input (step S1517: NO), the transaction management server 100 ends the series of processing. On the other hand, if there is an input for consignment (step S1517: YES), the current status is updated to "consignment" (step S1518), and the series of processing ends.

(Example of processing related to sending screen information performed by transaction management server 100)
FIG. 16 is a flowchart illustrating an example of processing related to transmission of screen information performed by the transaction management server 100. Note that the process shown in FIG. 16 is a process that is always started (regularly at very short time intervals) in the transaction management server 100. In FIG. 16, the transaction management server 100 determines whether a viewing request has been received (step S1601). If the viewing request is not received (step S1601: NO), the transaction management server 100 ends the series of processes.

On the other hand, when a viewing request is received (step S1601: YES), the transaction management server 100 determines whether the requesting source of the viewing request is the user terminal device 120 (step S1602). If the request source of the viewing request is the user terminal device 120 (step S1602: YES), the transaction management server 100 extracts the transaction information of the user based on the user ID included in the viewing request (step S1603). Then, the transaction management server 100 transmits screen information including only the extracted transaction information to the user terminal device 120 (step S1604), and ends the series of processing.

On the other hand, in step S1602, if the request for viewing is not made by the user terminal device 120 (step S1602: NO), i.e., if the request for viewing is made by the factory terminal device 110, the transaction management server 100 transmits screen information including all transaction information to the factory terminal device 110 (step S1605), and ends the series of processes.

As explained above, the transaction management server 100 according to the present embodiment provides status information corresponding to each process based on progress status information (input information) received from work staff in each process including the content evaluation process. and transmits screen information including status information to the user terminal device in response to a viewing request from the user terminal device. Thereby, it is possible to notify the user of the status in transactions related to recycled raw materials. Therefore, the user can grasp the current status. Therefore, the steps of the content evaluation process can be made clear to the user. Therefore, according to this embodiment, it is possible to clarify transactions related to recycled raw materials.

Further, the transaction management server 100 according to the present embodiment updates the status information in response to acquisition of evaluation results received in each evaluation process, such as wet amount, moisture value, component value, etc. This allows the status information to be updated in response to input of evaluation results from the work staff. Therefore, status information can be updated easily and accurately.

Further, the transaction management server 100 according to the present embodiment transmits screen information including the evaluation results in the evaluation process to the user terminal device 120 in response to a viewing request from the user terminal device 120. This allows the user to check the evaluation results for each evaluation step. Therefore, the evaluation process can be made clear to the user.

In addition, the transaction management server 100 according to this embodiment transmits a confirmation notification to the user terminal device 120 based on any discrepancy between the expected information 521 (see FIG. 5) specified by the user and the information entered by the work staff. In this way, if there is a discrepancy between the user's expectations and the factory's view, a confirmation notification can be sent to obtain the user's acceptance or rejection of the discrepancy. This can prevent discrepancies between the user and the recycling factory, thereby improving the reliability of the transaction. In addition, the user can be made to quickly confirm the discrepancy, which can speed up the transaction.

Further, the transaction management server 100 according to the present embodiment transmits a confirmation notification to the user terminal device 120 based on the discrepancy between the wet weight measurement result and the expected weight predicted by the user. As a result, if there is a discrepancy between the estimated weight and the weighing result, it is possible to have the user confirm the discrepancy regarding the weighing with a confirmation notification, and also obtain consent or refusal from the user regarding the discrepancy. . Therefore, since it is possible to suppress the occurrence of discrepancies between the user and the recycling factory, it is possible to improve the reliability of transactions. In addition, since the user can quickly confirm the discrepancy in measurement, it is possible to prevent delays in the post-measurement process and speed up the transaction.

Further, the transaction management server 100 according to the present embodiment transmits a confirmation notification to the user terminal device 120 based on the discrepancy between the sampling method specified by the user and the sampling method specified by the work staff. As a result, if there is a discrepancy between the two sampling methods, it is possible to confirm the discrepancy in the sampling methods using the confirmation notification, and to obtain approval or rejection regarding the discrepancy from the user. Therefore, since it is possible to suppress the occurrence of discrepancies between the user and the recycling factory, it is possible to improve the reliability of transactions. Further, since the user can quickly confirm the deviation related to the sampling method, it is possible to prevent delays in the steps after the sampling step and to speed up the transaction.

Further, the transaction management server 100 according to the present embodiment transmits screen information including image data (sampling video) of recycled raw materials imaged by the work staff in response to a viewing request from the user terminal device 120. Thereby, the sampling process can be visualized using the sampling video 831. Therefore, the user can confirm the sampling process by watching the sampling video 831.

(Modified example of embodiment)
Modifications of the embodiment will be described below. In addition, in each of the following modified examples, description of the contents described in the above-mentioned embodiment will be omitted as appropriate. In a modification, an example will be described in which the state of unpacking of recycled raw materials received at a recycling factory is visualized.

Recycled raw materials are delivered to recycling plants in various delivery formats. Examples of the delivery form include a form where the product is stored as is in a container of a transport vehicle, or a form where the product is packed in a flexible container bag. Once the recycled materials have been weighed, they are unpacked. That is, the unpacking work is performed when the status is "weighed/inspecting" after "arrived/waiting for weighing". Unpacking work is done on a lot-by-lot basis.

FIG. 17A is a diagram showing a state in which recycled raw materials are unpacked from a container of a transport vehicle. As shown in FIG. 17A, the transport vehicle 1711 includes a container 1712. In the container 1712, for example, a logo 1712a of a transportation company (for example, "○× transportation"), etc., which the user knows by requesting transportation, etc., is written. Recycled raw material 1713 is accommodated in the container 1712 as it is.

The transport vehicle 1711 unpacks the container 1712 in an unpacking area 1714 within the recycling factory. Unpacking area 1714 includes multiple placement areas 1716. The plurality of placement areas 1716 are areas in which the recycled raw materials 1713 of each user can be placed, respectively. When the transport vehicle 1711 arrives at the unpacking area 1714 in the recycling factory, the container 1712 is opened and tilted in a predetermined loading area 1716 in accordance with the operation of the work staff 1715. As a result, the recycled raw material 1713 in the container 1712 is released to a predetermined placement area in the unpacking area 1714.

FIG. 17B is a diagram showing the situation when raw materials packed in a flexible container bag are unpacked. As shown in FIG. 17B, the flexible container bag 1721 is transported to an unpacking area 1714 by a forklift 1722. In the flexible container bag 1721, a predetermined flexible container bag number 1721a (for example, "S123"), which is known by the user due to packaging etc., is written. The flexible container bag number 1721a is associated with a lot number.

The forklift 1722 moves to a predetermined placement area 1716 within the unpacking area 1714 and unpacks the flexible container bag 1721. Specifically, when a part of the flexible container bag 1721 is cut by the work staff 1715 with a knife or the like in a predetermined placement area 1716, the recycled raw material 1713 in the flexible container bag 1721 is released to the predetermined placement area 1716. . The unpacking state shown in FIGS. 17A and 17B is captured by a predetermined imaging device.

Next, an example of installing the imaging device will be described.
FIG. 18 is a diagram illustrating an example of how an imaging device is installed within the unpacking area 1714. As shown in FIG. 18, the imaging device 1800 is, for example, a plurality of fixed point cameras. The imaging devices 1800 are arranged corresponding to a plurality of placement areas 1716 (1716a to 1716f) in the unpacking area 1714, and for example, the same number (for example, 6) as the number of placement areas 1716 are arranged. The image captured by the imaging device 1800 (hereinafter referred to as "unpacking image") is, for example, a moving image. The imaging device 1800 images a series of operations from when the transport vehicle 1711 or the forklift 1722 enters the unpacking area 1714 until the recycled raw material 1713 is released into the unpacking area 1714.

For example, in the plurality of placement areas 1716, imaging buttons 1801 for activating the corresponding imaging devices 1800 are arranged on a wall surface, a pillar, or the like. For example, the work staff 1715 who performs unpacking work in the placement area 1716a presses the imaging button 1801 corresponding to the placement area 1716a before the unpacking work. As a result, the imaging device 1800 corresponding to the placement area 1716 starts capturing an unpacking image. After completing the unpacking work, the work staff 1715 presses the image capture button 1801 again. Thereby, the imaging device 1800 finishes capturing the unpacking image.

Note that the imaging device 1800 may change the imaging direction or enlarge the image using a zoom lens. Further, a plurality of imaging devices 1800 may be arranged at different positions with respect to one mounting area 1716. In this case, unpacking images may be captured by a plurality of imaging devices 1800 from a plurality of angles.

Further, the number of imaging devices 1800 arranged in the unpacking area 1714 does not have to be the same as the number of placement areas 1716, and may be smaller than the number of placement areas 1716, for example. In this case, the imaging device 1800 changes the imaging direction or enlarges the image using a zoom lens in order to image each of the plurality of placement areas 1716. When the work staff 1715 presses the imaging button 1801 corresponding to the placement area 1716, the imaging device 1800 specifies the placement area 1716 indicated by the imaging button 1801, turns in the direction of the specified placement area 1716, and zooms in. and take an image. Even in this case, an unpacking image within the placement area 1716 can be captured.

Note that if the imaging device 1800 is capturing an unpacking image of another placement area 1716 when the imaging button 1801 is pressed, a notification may be issued indicating that the imaging is on standby. . The notification may be made by a sound placed in the unpacking area 1714 or a display (image or lamp) placed on a wall or the like. Further, the imaging device 1800 is not limited to a fixed-point camera, and may be a camera (for example, a smartphone) owned by a work staff member. Further, the unpacking image is not limited to a moving image, and may be a still image.

The captured unpacking image is stored in association with the date and time. The unpacking image is transmitted to the transaction management server 100 at a predetermined timing and stored in the transaction management DB 101. Further, the transaction management server 100 transmits an unpacking image to the user terminal device 120 in response to a user's viewing request.

FIG. 19 is an explanatory diagram showing an example of a viewing screen including an unpacking image. The viewing screen 1900 shown in FIG. 19 is different from the viewing screen 800 shown in FIG. different. The unpacking image 1901 may be a video that is played as is on the viewing screen 1900, or may be an icon that accepts playback of the video.

The user can check the transportation company's logo 1712a (for example, "XX Transportation") and the flexible container bag number 1721a (for example, "S123") from the unpacking image 1901. This allows users to easily confirm that their recycled materials have been properly unpacked.

As described above, the transaction management server 100 according to the first modification registers the captured unpacking image in the transaction management DB 101, and displays screen information including the unpacking image in response to a viewing request from the user terminal device 120. It is transmitted to the user terminal device 120. This makes it possible to visualize the unpacking work, thereby further improving the reliability of transactions of recycled raw materials.
