[0038] (Implementation Manner)

[0039] (Network Structure of Transaction Management System 1)

[0040] Figure 1 is an explanatory diagram showing the network structure of the transaction management system 1 involved in the implementation manner. As Figure 1 shown, 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 via a network 140 (for example, a TCP / IP-based network, a mobile network, etc.). And each device is a computer device having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a communication unit, etc.

[0041] (Transaction Management Server 100)

[0042] The transaction management server 100 is an example of a transaction management device. The transaction management server 100 manages the trading of valuable metals between users as recycling enterprises and recycling factories such as smelters (recycling processing enterprises). In the transaction, the user delivers the recycling raw material (waste) to the recycling factory. The recycling raw material can be directly brought into the recycling factory by the user or brought into the recycling factory through a third party.

[0043] The recycling raw material contains valuable metals. Valuable metals include, for example, gold, silver, copper, etc. The user obtains an equivalent reward corresponding to the valuable metals contained in the recycling raw material from the recycling factory. The equivalent reward of the valuable metals undergoes a content evaluation process of the valuable metals in the recycling factory, and is determined according to the evaluation result. The content evaluation process includes multiple processes such as weight measurement of the raw material, crushing / quartering / sampling, moisture measurement, analysis of the contained metals, etc. Valuable metals are metals expected to become trading objects. According to the evaluation result, the recycling raw material may not contain valuable metals.

[0044] The transaction management server 100 has a transaction management DB (database) 101 (an example of a registration institution), and manages transaction information for each user according to the content stored in the transaction management DB 101. Transaction information includes various schedules such as the scheduled delivery date or delivery quantity of the recycling raw material brought into the recycling factory, as well as the evaluation results in the content evaluation process. In addition, for the detailed content of the transaction management DB 101, use Figure 4A and Figure 4B 、 Figure 4CIt will be described later.

[0045] (Factory terminal device 110)

[0046] The factory terminal device 110 is arranged in the working area of each process in the recycling factory. That is, the number of factory terminal devices 110 corresponds to the working area. The factory terminal device 110 is, for example, a computer device such as a personal computer, a smart phone, or a tablet terminal. In each process involved in the transaction, the factory terminal device 110 receives various operations from the staff (factory staff).

[0047] For example, the factory terminal device 110 receives an input operation indicating the start of each process, various input operations in each process, or an input operation for the LOT number assigned to each raw material. The LOT number is identification information attached to each recycled raw material transported into the 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 associated with and marked on the recycled raw material, and is read by a reader such as a scanner or a camera. The staff uses the reader to read the raw material identification code. Thus, the factory terminal device 110 can obtain the raw material identification code.

[0048] The factory terminal device 110 sends the input information received according to the operations of the staff to the transaction management server 100. The transaction management server 100 registers the input information received from the factory terminal device 110 in the transaction management DB 101.

[0049] (User terminal device 120)

[0050] The user terminal device 120 is held by the user. The number of user terminal devices 120 corresponds to the number of users. The user terminal device 120 is, for example, a computer device such as a personal computer, a smart phone, or a tablet terminal. For example, according to the operations of the user, the user terminal device 120 receives a reservation related to the transaction of recycled raw materials, and sends transaction information indicating the received reservation to the transaction management server 100. The transaction management server 100 registers the transaction information received from the user terminal device 120 in the transaction management DB 101.

[0051] (Hardware structure of the transaction management server 100)

[0052] Figure 2 is a block diagram showing an example of the hardware structure of the transaction management server 100. In Figure 2 the transaction management server 100 includes a CPU 201, a memory 202, a communication I / F (interface) 203, and a storage medium I / F 204. Each part is connected via a bus 220 respectively.

[0053] The CPU 201 is responsible for the overall control of the transaction management server 100. The memory 202 has, for example, a ROM, a RAM, and a flash ROM. For example, the ROM or the flash ROM stores various programs such as the transaction management program related to the present embodiment. The RAM is used as a work area for the CPU 201. The programs stored in the memory 202 are loaded into the CPU 201 to cause the CPU 201 to execute the encoded processing.

[0054] The communication I / F 203 is connected to a network 140 such as the Internet via a communication line and is connected to other devices (for example, the factory terminal device 110 or the user terminal device 120) via the network 140. Further, the communication I / F 203 is responsible for the interface between the network 140 and the inside of the device and controls the input / output of data from other devices.

[0055] The storage medium I / F 204 controls the reading from and writing to a storage medium such as a USB (Universal Serial Bus) flash memory, an SSD (Solid State Drive), a magnetic disk, an optical disk, or the transaction management DB 101 under the control of the CPU 201.

[0056] (Hardware Structure of Factory Terminal Device 110 and User Terminal Device 120)

[0057] Figure 3 is a block diagram showing an example of the hardware structure of the factory terminal device 110 and the user terminal device 120. In Figure 3 the factory terminal device 110 and the user terminal device 120 each include a CPU 301, a memory 302, an input device 303, a communication I / F 304, an output device 305, and a storage medium I / F 306. Each unit is connected via a bus 320.

[0058] The CPU 301 is responsible for the overall control of the factory terminal device 110 and the user terminal device 120. The memory 302 has, for example, a ROM, a RAM, and a flash ROM. For example, the ROM or the flash ROM stores various programs such as the display control program related to the present embodiment.

[0059] The RAM is used as a work area for the CPU 301. The programs stored in the memory 302 are loaded into the CPU 301 to cause the CPU 301 to execute the encoded processing.

[0060] The input device 303 is a touch panel or an operation button. The input device 303 includes a keyboard, a mouse, a microphone, etc. Also, the input device includes a scanner or a camera. The scanner or the camera can read various codes such as QR codes. The reading method of the scanner is, for example, a laser method or a CCD method, etc. The camera uses a CCD (charge coupled device) camera or a CMOS (Complementary Metal Oxide Semiconductor) camera.

[0061] The communication I / F 304 is connected to a network 140 such as the Internet through a communication line and is connected to other devices (for example, the transaction management server 100) via the network 140. Also, the communication I / F 304 is responsible for the interface between the network 140 and the inside of this device and controls the input and output of data from other devices.

[0062] The output device 305 includes a display, a speaker, etc. The display shows images and can be, for example, a touch panel type display. The speaker outputs sound.

[0063] The storage medium I / F 306 controls the reading and writing of data to / from a storage medium (not shown) such as a USB flash drive, an SSD, a disk, an optical disc, etc. according to the control of the CPU 301.

[0064] (An example of the transaction information stored in the transaction management DB 101)

[0065] Figure 4A and Figure 4B 、 Figure 4C is an explanatory diagram showing an example of the transaction information stored in the transaction management DB 101. Additionally, Figure 4A and Figure 4B 、 Figure 4C Due to the relationship with the size of the paper, it is explained in three figures, but it can also be shown in one figure. The transaction management DB 101 is implemented by the memory 202.

[0066] In Figure 4A and Figure 4B 、 Figure 4CAmong them, the transaction management DB 101 includes items such as "user name", "user ID", "LOT", "shipping guide manual number", "shipping date", "scheduled bringing-in date", "receiving location", "receiving date", "status", "raw material image", "estimated / determined", "sampling", "sampling dynamic image", "wet weight", "moisture", "dry weight", and "composition". Each item is input according to the operations of the staff on the factory terminal device 110 or the operations of the user on the user terminal device 120. By inputting the specified information for each item respectively, the transaction information 401 is stored in the transaction management DB 101 for each transaction.

[0067] Hereinafter, each item of the transaction management DB 101 will be described.

[0068] The "user name" is the name of the user (for example, company name, branch name, office name, etc.).

[0069] The "user ID" is the identification information that can uniquely identify the user as a recycling enterprise.

[0070] The "LOT" is the identification information that identifies the transaction related to the recycled raw materials brought in by the user. The "LOT" is attached at each transaction. Therefore, in the case of transporting the same type of recycled raw materials in multiple containers, the same LOT is attached to the recycled raw materials in the multiple containers. On the other hand, in the case of transporting in one container, the LOT is attached to the valuable recycling in one container.

[0071] The "shipping guide manual number" is the identification number that identifies the shipping guide manual issued before shipping. The shipping guide manual is a document or electronic data that records the entrusted matters such as the received reservation content and shipping method according to the reservation related to the transaction of the recycled raw materials.

[0072] The "shipping date" is the date when the user ships the recycled raw materials.

[0073] The "scheduled bringing-in date" is the scheduled date when the user brings the recycled raw materials into the recycling factory.

[0074] The "receiving location" is the smelter (recycling factory) where the recycled raw materials are received.

[0075] The "receiving date" is the date when the recycling factory receives the recycled raw materials.

[0076] The "status" indicates the process related to the transaction of the recycled raw materials. There are, for example, 15 kinds of "status". In the figure, for the convenience of explanation, 15 kinds of status are shown. The detailed content of the "status" will be described later.

[0077] "Estimation / Determination" represents the information of the recycled raw materials brought in by the user, and represents the "estimation" input by the user at the time of reservation and the "determination" input by the staff during the content evaluation process.

[0078] "Raw material image" is the camera data of the recycled raw materials received by the recycling plant, for example, the camera data taken by the staff at the start of metering.

[0079] "Sampling" represents the sampling method. "Sampling" includes, for example, automatic sampling and manual sampling.

[0080] When sampling a part of the recycled raw materials as the object of the evaluation process, automatic sampling is used by the machine, and manual sampling is implemented by the staff with a shovel or the like. In manual sampling, the staff samples any part. In contrast, in automatic sampling, the machine automatically samples randomly. In cases where there are large-sized parts that are difficult to be broken by the machine, etc., automatic sampling may sometimes not be possible. In this case, manual sampling is selected.

[0081] "Sampling" includes "estimated" sampling and "determined" sampling. "Estimated" sampling is the sampling method expected by the user. "Determined" sampling is the sampling method judged in the recycling plant. "Estimated" sampling may sometimes be different from "determined" sampling.

[0082] For example, the user expects automatic sampling, but sometimes manual sampling is more suitable than automatic sampling. A situation where manual sampling is more suitable is, for example, a situation where there is a lot of metal, in other words, a situation where the crusher may be damaged. In this case, with the consent of the user, the sampling method is changed. In addition, in the illustration, two sampling methods are shown, but it is not limited to two, and it can also be set to three or more. For example, the sampling method of automatic sampling can include high-quality sampling that combines two-stage crushing and reduction with eddy current separation between two-stage crushing, large-batch sampling based on four-axis crushing, sampling using a single-axis crusher or a Snyder sampler, and other various sampling methods.

[0083] "Sampling moving image" is the camera data during sampling taken by the staff during the sampling process.

[0084] "Moisture content" represents the weight of the recycled raw materials including moisture. "Moisture content" includes "estimated" moisture content and "determined" moisture content. "Estimated" moisture content is the moisture content input by the user. "Determined" sampling is the actual moisture content (evaluation result) measured by the staff. In the state where the measurement of the moisture content is not completed ("awaiting arrival" state and "being metered / checked" state), the "determined" moisture content in the transaction information 401 shows "NULL".

[0085] "Moisture content" represents the amount of moisture contained in the recycled raw material (evaluation result). In the state where the moisture content measurement has not been completed (the state until "moisture value measurement in progress"), the wet weight "determined" in the transaction information 401 shows "NULL".

[0086] "Dry weight" represents the weight of the recycled raw material after drying (evaluation result). In the state where the moisture content measurement has not been completed (the state until "moisture value measurement in progress"), the dry weight "determined" in the transaction information 401 shows "NULL".

[0087] "Composition" represents the composition of each metal contained in the recycled raw material (evaluation result), such as gold, silver, copper, etc. In the state where the composition analysis has not been completed (the state until "analysis in progress"), the composition "determined" in the transaction information 401 shows "NULL".

[0088] (Regarding the state)

[0089] Hereinafter, 15 states will be described.

[0090] (1) "Pending arrival": Represents the period from the reservation until the recycled raw material is transported into the receiving site.

[0091] (2) "Arrived / Pending measurement": Represents that the acceptance is completed by unloading the recycled raw material into the receiving site and the measurement is being prepared. If the recycled raw material is transported in, a QR code (raw material identification code) indicating the identification information (such as LOT) of the transaction (recycled raw material) is attached. The factory terminal device 110 can read the raw material identification code according to the operation of the staff in each process and input the LOT number. In addition, the input information in each process is associated with the LOT number and sent to the transaction management server 100. In addition, the raw material identification code can be any information that can identify the recycled raw material, and can also be information other than the LOT number.

[0092] (3) "Measured / Inspecting": Represents that the measurement (including wet weight) of the recycled raw material is completed and is being inspected in the sampling yard.

[0119] (An example of a reservation screen related to the exchange of recycled raw materials)

[0120] Next, use Figure 5 to explain the reservation screen displayed on the user terminal device 120.

[0121] Figure 5 is an explanatory diagram showing an example of the reservation screen displayed on the user terminal device 120. In Figure 5 , the reservation screen 500 is a screen displayed by pressing (selecting) a reservation start button displayed on the main screen (not shown). The reservation screen 500 accepts various inputs from the user.

[0122] Specifically, the reservation screen 500 includes various input fields. More specifically, the reservation screen 500 includes a basic information input field 510 and a batch information input field 520. The basic information input field 510 includes columns for "shipment date", "scheduled arrival date", "acceptance location", "raw material group", "transportation agency", "transportation company", "license plate number", "driver", "number of vehicles", and "remarks". In each column, for example, text or numbers can be input from a drop-down menu, or text or numbers can be directly input.

[0123] The "shipment date" column accepts the designation of the date when the user ships the recycled raw materials. The "scheduled arrival date" column accepts the designation of the scheduled date when the user brings in the recycled raw materials. The "acceptance location" column accepts the designation of the smelter (factory) where the recycled raw materials are accepted. The "raw material group" column accepts the designation of recycled raw materials or precious metal raw materials as raw materials for precious metals. In this embodiment, the user designates the recycled raw materials. The "transportation agency" column accepts, for example, the designation of the business office that handles the transportation of the recycled raw materials. The columns for "transportation company", "license plate number", "driver", and "number of vehicles" accept the input of various information related to the transportation of the recycled raw materials.

[0124] The batch information input field 520 includes "item name", "goods form", and estimated information 521. The "item name" column accepts the designation of item names such as gold and silver slag, parts, unbroken substrates, and sludge. The "goods form" column accepts the input of the type of container for bundling the recycled raw materials and the quantity of the containers.

[0125] The estimated information 521 represents the estimated information related to the exchange specified by the user. Specifically, the estimated information 521 represents the information input into each column of the desired sampling 521a, the moisture content 521b, and the quality 521c. The desired sampling 521a column accepts the sampling method desired by the user. Specifically, the desired sampling 521a column accepts, for example, the input of any one of automatic sampling, manual sampling, and no specification.

[0126] The moisture content 521b column is related to the weight of the recycled raw material and accepts the input of the estimated weight including moisture predicted by the user.

[0127] The quality 521c column accepts the input of the estimated content rate (or content) of each component contained in the recycled raw material.

[0128] In the reservation screen 500, if an item is input in various input columns and the confirmation button 530 is pressed, it transitions to a confirmation screen (not shown). In the confirmation screen, if the confirmation of the reservation content is received, the reservation content is determined. If the reservation content is determined, the user terminal device 120 sends transaction information indicating the determined reservation content to the transaction management server 100. Then, the transaction management server 100 registers the transaction information in the transaction management DB 101.

[0129] (An example of the functional structure of the transaction management system 1)

[0130] Next, the functional structure of the transaction management system 1 will be described.

[0131] Figure 6 It is a block diagram showing an example of the functional structure of the transaction management system 1. In Figure 6 the transaction management server 100 includes an input information acquisition unit 601, an update unit 602, a transmission unit 603, an extraction unit 604, and an estimated information acquisition unit 605. Each unit is implemented by the CPU 201 included in the transaction management server 100. That is, the functions of each unit are realized by the CPU 201 executing the transaction management program stored in the memory 202.

[0132] In addition, the user terminal device 120 includes a request unit 611, a reception unit 612, and a display control unit 613. Each unit is implemented by the CPU 301 included in the user terminal device 120. That is, the functions of each unit are realized by the CPU 301 executing the display control program stored in the memory 302.

[0133] The input information acquisition unit 601 is an example of an information acquisition mechanism. The input information acquisition unit 601 acquires information on the progress status in each process including the content evaluation process of the transaction related to the recycled raw material. Each process is a process corresponding to each state. The information on the progress status includes, for example, the input information received from the staff in each process. The input information is information based on the specified input related to the status update. The input information includes the evaluation result in the content evaluation process.

[0134] The update unit 602 updates the status information corresponding to each process according to the input information acquired by the input information acquisition unit 601. The status information is the information indicating the status in the transaction information registered in the transaction management DB 101. Regarding the update of the status information, for example, as described above, if the current status is "awaiting arrival", the update unit 602 updates the status to "arrived / awaiting measurement" by acquiring the input information indicating the arrival place of the recycled raw material.

[0135] (Browsing screen display by the user terminal device 120)

[0136] The user terminal device 120 can display a browsing screen according to the screen information including the transaction information. The request unit 611 of the user terminal device 120 makes a browsing request for the screen information to the transaction management server 100. The request unit 611 makes a browsing request by starting to display the browsing screen from the user. The user ID for identifying the user is included in the browsing request.

[0137] The sending unit 603 of the transaction management server 100 sends the screen information to the user terminal device 120 according to the browsing request from the request unit 611. The sent screen information includes all the transaction information related to the transactions of this user. That is, the sent screen information does not include the transaction information related to the transactions of other users different from this user.

[0138] When sending the screen information related to the transactions of this user, the corresponding transaction information is extracted. Specifically, the extraction unit 604 extracts the transaction information corresponding to the user ID according to the user ID included in the browsing request. The sending unit 603 sends the screen information only including the transaction information extracted by the extraction unit 604 to the user terminal device 120.

[0139] In addition, the sent screen information can also be set to the specific transaction information specified by the user among all the transaction information related to the transactions of this user. In this case, in the browsing request, as long as the LOT number is included to determine the transaction information. The extraction unit 604 only needs to extract the transaction information including the LOT number according to the LOT number included in the browsing request.

[0140] Moreover, the transmitting unit 603 not only transmits the screen information to the user terminal device 120, but also transmits the screen information to the factory terminal device 110. Specifically, the transmitting unit 603 transmits the screen information indicating the transaction information to the factory terminal device 110. The screen information transmitted to the factory terminal device 110 includes all the transaction information involved in the transactions, that is, it includes the transaction information for which extraction by the extraction unit 604 has not been performed. The timing for transmitting the screen information to the factory terminal device 110 can be set when a browsing request from the factory terminal device 110 appears, can be set at regular intervals (sequentially), or can be set when a new reservation is received from the user terminal device 120.

[0141] The receiving unit 612 receives the screen information from the transaction management server 100 according to the browsing request of the requesting unit 611. The display control unit 613 displays the screen information received by the receiving unit 612 on the display (display unit). Thus, the user terminal device 120 can display the status during the content evaluation process. Regarding the example of the screen displayed by the display control unit 613, it will be described later. Figures 9 - 11 It will be described later.

[0142] (Regarding the update of the status based on the input of the evaluation result)

[0143] The processes during the content evaluation process include the evaluation processes related to the evaluation of the recycled raw materials. The evaluation processes include, for example, the process of measuring the recycled raw materials, the process of measuring the moisture value, and the process of analyzing the component value. The input information acquisition unit 601 acquires the evaluation results received in the evaluation processes as input information. The evaluation results are, for example, the wet weight, the moisture content, and the components.

[0144] The update unit 602 updates the status information according to the evaluation results acquired by the input information acquisition unit 601. As described above, for example, if the current status is "measuring moisture value", the update unit 602 updates the status to "analyzing" by inputting the moisture value as the input information.

[0145] (Regarding the transmission of the evaluation result)

[0146] The screen information transmitted by the transmitting unit 603 includes the evaluation results. That is, the transmitting unit 603 transmits the screen information including the evaluation results to the user terminal device 120 according to the browsing request from the user terminal device 120. The user terminal device 120 displays the screen information including the evaluation results. Thus, the user can confirm the evaluation results.

[0147] (Regarding the notification in the case where there is a deviation between the estimated information and the input information)

[0148] The estimated information acquisition unit 605 acquires the estimated information 521 (refer to Figure 5)。The sending unit 603 sends a confirmation notice based on the deviation between the estimated information 521 and the input information to the user terminal device 120. Specifically, as described above, the estimated information 521 includes the sampling method desired by the user, the estimated weight (wet weight) of the recycled raw material specified by the user, and the composition. And it includes the measurement result in the process of measuring the recycled raw material.

[0149] The sending unit 603 sends a confirmation notice based on the deviation between the estimated weight and the measurement result to the user terminal device 120. For example, when there is a deviation of more than a specified deviation rate (e.g., 5%) between the estimated weight and the measurement result, the sending unit 603 sends a confirmation notice to the user terminal device 120. On the other hand, when there is no deviation of more than the specified deviation rate (5%) between the estimated weight and the measurement result, the sending unit 603 does not send a confirmation notice to the user terminal device 120. The sending of this confirmation notice is performed according to the operation related to the sending by the staff, but it can also be performed automatically.

[0150] Here, use Figure 7 to illustrate the browsing screen indicating that the confirmation notice regarding the weight has been made.

[0151] Figure 7 is an explanatory diagram showing an example of the browsing screen indicating that the confirmation notice regarding the weight has been made. In Figure 7 , the browsing screen 700 includes a weight information column 710, a person in charge column 720, and a camera data area 730. The weight information column 710 includes the estimated wet weight input by the user, the measured wet weight by the staff, the deviation rate, etc.

[0152] When the deviation rate is 5% or more, the factory terminal device 110 receives a specified operation related to the confirmation notice sent to the user (e.g., email sending) from the staff. If the factory terminal device 110 receives the specified operation from the staff, it sends a confirmation notice to the user terminal device 120. The name of the staff who sent this confirmation notice (○○ Ichiro, Business Section of ○○ Smelter) is displayed as the registrant on the browsing screen 700.

[0153] When the user terminal device 120 receives a confirmation notice, regarding the deviation, it obtains consent or rejection from the user. The screen for obtaining consent or rejection can be on the browsing screen 700 or on another screen (for example, the mail screen). The browsing screen 700 shows the screen for obtaining consent from the user regarding the deviation. Specifically, in the person in charge column 720, the user name (Saburo ○○: Company A Co., Ltd.) who has consented to the change is displayed in the confirmator and updater columns. In addition, when the user terminal device 120 receives rejection from the user regarding the deviation, it only needs to further receive the transaction suspension. Also, a request for re-analysis can be received from the user, and when there is still a deviation during the re-analysis, a request for further re-analysis can be received.

[0154] (Regarding the imaging data area 730)

[0155] Raw material image data 731 is displayed in the imaging data area 730. The raw material image data 731 is an image of the recycled raw material received by the recycling factory and represents the image at the start of weighing the recycled raw material. This image is taken by a staff member, for example, in the process to be weighed. The device used for taking the image is, for example, a smartphone as the factory terminal device 110. A prescribed application program (application software) related to the transaction management system 1 is pre-installed in this smartphone. The staff member starts this application program to take an image of the recycled raw material. The factory terminal device 110 uploads the raw material image data 731 obtained by the imaging to the transaction management server 100. Through this raw material image data 731, the recycled raw material received by the recycling factory can be visualized. Therefore, the user can easily confirm whether the recycled raw material shipped to the recycling factory is the same as the actually delivered recycled raw material through the raw material image data 731.

[0156] (Other examples of confirmation notices)

[0157] In the present embodiment, the confirmation notice is made not only when the deviation rate is 5% or more but also when the sampling method is changed. An explanation thereof will be given. As described above, the estimated information 521 includes information indicating one sampling method specified by the user among the multiple sampling methods used in the sampling process. And the input information includes information indicating the sampling method specified by the staff member. Sometimes the sampling method specified by the staff member is different from the one sampling method specified by the user. That is, the input information sometimes includes information indicating another sampling method different from the one sampling method specified by the user.

[0158] The sending unit 603 sends a confirmation notice based on one sampling method and another sampling method to the user terminal. Specifically, when there is a deviation between the two sampling methods, the sending unit 603 sends a confirmation notice to the user terminal device 120. On the other hand, when there is no deviation between the two sampling methods, the sending unit 603 does not send a confirmation notice to the user terminal device 120. The sending of this confirmation notice is carried out according to the operations involved in the sending by the staff, but it can also be carried out automatically.

[0159] Here, Figure 8 is used to explain the browsing screen indicating the confirmation notice related to the change of the sampling method.

[0160] Figure 8 is an explanatory diagram showing an example of the browsing screen indicating the confirmation notice related to the change of the sampling method. In Figure 8 , the browsing screen 800 includes a sampling information column 810, a person in charge column 820, and a camera 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 staff, the reason for the change, etc.

[0161] When changing the sampling method, the factory terminal device 110 receives the specified operations related to the confirmation notice sent to the user (for example, email sending) from the staff. If the factory terminal device 110 receives the specified operations from the staff, it sends a confirmation notice to the user terminal device 120. The name of the staff who sent this confirmation notice (Taro ○○, Business Section of ○○ Smelter) is displayed as the registrant on the browsing screen 800.

[0162] If the user terminal device 120 receives the confirmation notice, it receives consent or rejection from the user regarding the change of the sampling method. The screen for receiving consent or rejection can be on the browsing screen 800 or on other screens (for example, the email screen). The browsing screen 800 shows the screen for receiving consent from the user regarding the change of the sampling method. Specifically, in the person in charge column 820, the name of the user who consented to the change (Jiro ○○: A Co., Ltd.) is displayed in the confirmor and updater columns. In addition, when the user terminal device 120 receives rejection from the user regarding the change of the sampling method, it only needs to further accept the transaction suspension.

[0163] (Regarding the sampling moving image 831)

[0164] In the present embodiment, the process of the content evaluation process (evaluation process) includes the process of the staff photographing the recycled raw material. The process of taking the photograph is, for example, the sampling process. The camera data is, for example, a moving image (sampling moving image). In addition, the process of taking the photograph is not limited to the sampling process and can also be set as other processes.

[0165] The transmitting unit 603 transmits screen information including captured data to the user terminal device 120 according to a browsing request from the user terminal device 120. The user terminal device 120 displays a browsing screen 800 including the captured data. Specifically, raw material image data 731 and a sampled moving image 831 are attached in the captured data area 830. The sampled moving image 831 is captured by the responsible staff member in the sampling process.

[0166] The device for capturing is, for example, a smartphone as the factory terminal device 110. A prescribed application program (application software) related to the transaction management system 1 is pre-installed in the smartphone. The staff member starts the application program and captures a moving image in the sampling process. The factory terminal device 110 uploads the sampled moving image 831 obtained by capturing to the transaction management server 100. Through such a sampled moving image 831, the sampling process (sampling method, situation where sampling has been performed) can be visualized. Therefore, the user can easily confirm the sampling process related to the transaction.

[0167] (Transaction list browsing screen displayed on the user terminal device 120)

[0168] Figure 9 It is an explanatory diagram showing an example of the transaction list browsing screen displayed on the user terminal device 120. In Figure 9 , a list overview 900 related to the user's transactions is displayed on the display of the user terminal device 120. The list overview 900 includes detailed information such as the status 901a of each transaction 901, the shipping guide manual number 901b, etc. And the list overview 900 includes a horizontal scroll bar 910a and a vertical scroll bar 910b.

[0169] The user can also browse items other than those displayed on the screen by moving the horizontal scroll bar 910a to the right. And the user can browse transactions 901 in other states not displayed on the screen by moving the vertical scroll bar 910b downward.

[0170] In addition, the list overview 900 can also be displayed on the factory terminal device 110. In the factory terminal device 110, by performing filtering for this user, a screen identical to the list overview 900 can be displayed. In addition, without performing filtering, the factory terminal device 110 can display an overview of all users' transactions 901.

[0171] (Another screen example of the transaction list browsing screen)

[0172] Next, another screen example of the transaction list browsing screen will be described. In Figure 9In the list overview 900 shown, by operating a specified button for switching the operation acceptance screen, the display form of the list overview 900 can be changed. Use Figure 10 To explain a screen example with the changed display form.

[0173] Figure 10 It is an explanatory diagram of another screen example showing the transaction list browsing screen. In Figure 10 , on the display of the user terminal device 120, a group overview 1000 of each transaction is displayed. The group overview 1000 is a screen that classifies each status into three groups and displays them. For example, the groups are displayed as three groups: the acceptance incomplete group 1010, the analysis in-progress group 1020, and the analysis determined group 1030.

[0174] The acceptance incomplete group 1010 represents transaction information for each status of "awaiting arrival", "arrived / awaiting measurement", and "measured / under inspection".

[0175] The analysis in-progress group 1020 represents transaction information for each status of "sampling", "moisture value measuring", and "analysis in progress".

[0176] The analysis determined group 1030 represents transaction information for each status of "analytical value determined", "re-analysis value determined", "re-re-analysis value determined", "estimated payment", "settled payment", "re-payment", "re-re-payment", and "entrusted".

[0177] Furthermore, the group overview 1000 includes a scroll bar 1050. The user can browse other transactions 1001 that are not displayed on the screen for each of the groups 1010, 1020, and 1030 by moving the scroll bar 1050 downward.

[0178] In the group overview 1000, each transaction 1001 includes items such as a shipping guide manual number 1002, a status 1003, an item name 1004, and a scheduled bringing-in date 1005. Therefore, compared with the transaction 901 shown in the list overview 900, the number of displayed items of the transaction 1001 displayed on the group overview 1000 is smaller.

[0179] Also, the group list 1000 includes group displays 1040a, 1040b, and 1040c. The group displays 1040a, 1040b, and 1040c indicate statuses and are displayed for each group in different display manners (e.g., different colors). Also, the status displays 1003a, 1003b, and 1003c correspond to the group displays 1040a, 1040b, and 1040c and are displayed in the same display manner (e.g., the same color). Specifically, the group display 1040a and the status display 1003a are displayed in the same color. The group display 1040b and the status display 1003b are displayed in the same color. The group display 1040c and the status display 1003c are displayed in the same color.

[0180] In this way, in the group list 1000, the status is displayed separately for each group, so the general status can be grasped simply. Also, the user can identify each group 1010, 1020, and 1030 by color, so the general status can be grasped more simply. In addition, in the group list 1000, the user terminal device 120 can switch from the group list 1000 to the list view 900 by receiving a specified operation.

[0181] Also, regarding the factory terminal device 110, similarly to the user terminal device 120, it can display the list view or the group list. Also, the factory terminal device 110 can also perform switching from the list view to the group list or from the group list to the list view by operating a specified button for accepting the screen switch.

[0182] (Detailed view screen displayed on the user terminal device 120)

[0183] Next, the detailed view screen displayed on the user terminal device 120 will be described. In Figure 9 the list view 900 shown or Figure 10 the group list 1000 shown, if a specified button (e.g., the shipping guide manual number 901b, 1002 corresponding to the transaction) is pressed, then it transitions to the detailed view screen of the acceptance status. Regarding the detailed view screen, Figure 11 will be used for the description. Also, in Figure 11 the detailed view screen of the transaction regarding the status of the "confirmed analysis value" will be described.

[0184] Figure 11 is an explanatory diagram showing an example of the detailed view screen displayed on the user terminal device 120. In Figure 11In the detailed view screen 1100, the batch information 1110 is included. The batch information 1110 includes items such as "Item Name", "Receiving Date", "LOT", "Status", "Wet Weight", "Moisture Content", "Dry Weight", "Composition", and "Sampling". "Wet Weight", "Composition", and "Sampling" include the estimated information 521 input in the reservation screen 500 (refer to Figure 5 ) or the evaluation results input in the recycling plant.

[0185] Through this detailed view screen 1100, the user can comprehensively grasp the evaluation results, etc. of each transaction through simple operations.

[0186] (Regarding the processing flow in the transaction management system 1)

[0187] Next, Figure 12 the processing flow in the transaction management system 1 will be described.

[0188] Figure 12 is a sequence diagram showing the processing flow in the transaction management system 1. In Figure 12 , the user terminal device 120 receives the reservation registration of the transaction from the user (step S1201). If the user terminal device 120 receives the reservation registration, it sends the received reservation content to the transaction management server 100.

[0189] If the transaction management server 100 receives the reservation content from the user terminal device 120, it registers the received reservation content as transaction information in the transaction management DB 101 (step S1202). Then, the transaction management server 100 sends the transaction information to the factory terminal device 110.

[0190] If the factory terminal device 110 receives the transaction information from the transaction management server 100, it displays the received transaction information on the display (step S1203). Then, the factory terminal device 110 accepts the specified input related to the status update such as the evaluation result according to the operation of the staff (step S1204). If the factory terminal device 110 receives the specified input, it sends the input information corresponding to the received input to the transaction management server 100.

[0191] If the transaction management server 100 receives the input information from the factory terminal device 110, it updates the transaction information according to the input information (step S1205). The update of the transaction information includes the update of the status. In addition, whenever there is a specified input from the staff, the processing of steps S1204 and S1205 is repeated.

[0192] If the user terminal device 120 receives an operation to start browsing the browsing screen from the user, it makes a browsing request to the transaction management server 100 (step S1206). If the transaction management server 100 receives a browsing request from the user terminal device 120, it extracts the transaction information of the user according to the user ID included in the browsing request (step S1207). Then, the transaction management server 100 sends the screen information including only the extracted transaction information to the user terminal device 120. The user terminal device 120 displays a list of browsing screens including its own (the company's) transaction information received from the transaction management server 100 on the display (step S1208).

[0193] Also, if the factory terminal device 110 receives an operation to start browsing the browsing screen from the staff, it makes a browsing request to the transaction management server 100 (step S1209). In addition, regarding the request to start browsing, it can be automatically performed regularly when the factory terminal device 110 is started. If the transaction management server 100 receives a browsing request from the factory terminal device 110, it sends all the screen information to the user terminal device 120. The user terminal device 120 displays a list of browsing screens including all the transaction information received from the transaction management server 100 on the display (step S1210). In addition, the factory terminal device 110 can display a browsing screen including only the transaction information of a specific user from the list display of all the transaction information through the filtering function.

[0194] Next, the processing performed by the user terminal device 120 and the processing performed by the transaction management server 100 will be described separately. First, the processing performed by the user terminal device 120 will be described.

[0195] (An example of the processing performed by the user terminal device 120)

[0196] Figure 13 is a flowchart showing an example of the processing performed by the user terminal device 120. In addition, Figure 13 the processing shown is the processing that is frequently (regularly at very short time intervals) started in the user terminal device 120. In Figure 13 , the user terminal device 120 determines whether it has received an operation to start a new reservation registration related to the transaction (step S1301). If it has not received an operation to start a new reservation registration (step S1301: No), the user terminal device 120 proceeds to the processing of step S1304.

[0197] When a start operation for new reservation registration is received (Step S1301: Yes), the user terminal device 120 receives input of various reservation contents (Step S1302). Then, if the reservation contents are determined, the user terminal device 120 sends transaction information indicating the reservation contents to the transaction management server 100 (Step S1303).

[0198] Next, the user terminal device 120 determines whether a start operation for browsing is received (Step S1304). If a start operation for browsing is not received (Step S1304: No), the user terminal device 120 ends a series of processes. If a start operation for browsing is received (Step S1304: Yes), the user terminal device 120 sends a browsing request to the transaction management server 100 (Step S1305).

[0199] The user terminal device 120 receives screen information including only its own transaction information from the transaction management server 100 according to the browsing request (Step S1306). Then, the user terminal device 120 displays the screen information including only its own transaction information received from the transaction management server 100 in a list on the display (Step S1307). Next, the user terminal device 120 determines whether a display switch is received (Step S1308). The display switch is, for example, a switch to any one of a plurality of screens including a list overview 900, a group overview 1000, and a detailed browsing screen 1100.

[0200] If a display switch is not received (Step S1308: No), the user terminal device 120 ends a series of processes. On the other hand, if a display switch is received (Step S1308: Yes), the user terminal device 120 performs a display switch to a browsing screen corresponding to the received operation (Step S1309) and ends a series of processes.

[0201] (An example of the process related to the update of the status performed by the transaction management server 100)

[0202] Figure 14 and Figure 15 is a flowchart showing an example of the process related to the update of the status performed by the transaction management server 100. In addition, Figure 14 and Figure 15 the processes shown are processes that are regularly started (at very short time intervals) in the transaction management server 100. In Figure 14 the transaction management server 100 determines whether reservation contents indicating new reservation registration are received from the user terminal device 120 (Step S1401). If reservation contents indicating new reservation registration are not received (Step S1401: No), the transaction management server 100 proceeds to the process of Step S1403.

[0203] On the other hand, when receiving the reservation content indicating a new reservation registration (step S1401: Yes), the transaction management server 100 registers the reservation content received from the user terminal device 120 as transaction information in the transaction management DB 101 (step S1402). Then, the transaction management server 100 determines whether the recycled raw material has arrived (step S1403). Specifically, the determination in step S1403 is to determine whether input information indicating such input is received from the factory terminal device 110 by the factory terminal device 110 receiving an input from a staff member indicating the arrival place of the recycled raw material.

[0204] In the case where 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, in the case where the recycled raw material has arrived (step S1403: Yes), the transaction management server 100 updates the status from "awaiting arrival" to "arrived / awaiting measurement" (step S1404).

[0205] Next, the transaction management server 100 determines whether raw material image data is received from the factory terminal device 110 (step S1405). In the case where the raw material image data is not received (step S1405: No), the transaction management server 100 proceeds to the process of step S1407. On the other hand, in the case where the raw material image data is received (step S1405: Yes), the transaction management server 100 registers the raw material image data in the transaction management DB 101 (step S1406). In addition, the raw material image data is associated with the LOT number and registered in the transaction information indicated by the LOT number.

[0206] Next, the transaction management server 100 determines whether there is a deviation between the sampling method specified by the user and the sampling method specified by the staff member (step S1407). In addition, the determination in step S1407 is not limited to being performed by the transaction management server 100 and can be performed by the staff member. In the case where there is no deviation in the sampling method (step S1407: No), the transaction management server 100 proceeds to the process of step S1409.

[0207] On the other hand, in the case where there is a deviation in the sampling method (step S1407: Yes), the transaction management server 100 sends a confirmation notice (such as an email) to the user terminal device 120 according to an instruction from the factory terminal device 110 (step S1408). Based on the information of the user's intention to consent received from the user terminal device 120 through this confirmation notice, the transaction management server 100 changes the sampling method. In addition, the change of the sampling method can also be carried out by accepting a confirmation operation from the staff through the factory terminal device 110 instead of or in addition to receiving the information of the user's intention to consent from the user terminal device 120.

[0208] Next, the transaction management server 100 determines whether there is an input of the moisture content (step S1409). Specifically, the determination in step S1409 is to determine whether the input information related to this input is received from the factory terminal device 110 by accepting the input of the moisture content from the staff by the factory terminal device 110. In the case where there is no input of the moisture content (step S1409: No), the transaction management server 100 proceeds to the process of step S1411. On the other hand, in the case where there is an input of the moisture content (step S1409: Yes), the status is updated from "Arrived / Pending Measurement" to "Measured / Under Inspection" (step S1410).

[0209] Next, the transaction management server 100 determines whether there is a deviation of 5% or more between the input moisture content and the estimated weight (step S1411). In the case where there is no deviation of 5% or more between the input moisture content and the estimated weight (step S1411: No), the transaction management server 100 proceeds to the process of step S1413. On the other hand, in the case where there is a deviation of 5% or more between the input moisture content and the estimated weight (step S1411: Yes), the transaction management server 100 sends a confirmation notice (such as an email) to the user terminal device 120 according to an instruction from the factory terminal device 110 (step S1412). If the information of the user's intention to consent is received from the user terminal device 120 through this confirmation notice, the transaction continues.

[0210] Next, the transaction management server 100 determines whether it is the start of sampling (step S1413). Specifically, the determination in step S1413 is to determine whether the input information indicating the start of sampling is received from the factory terminal device 110 by accepting the input indicating the start of sampling from the staff by the factory terminal device 110.

[0211] In the case where sampling has not started (step S1413: No), the transaction management server 100 proceeds to the process of step S1415. On the other hand, in the case where sampling has started (step S1413: Yes), the transaction management server 100 updates the status from "being metered / inspected" to "sampling" (step S1414).

[0212] Next, the transaction management server 100 determines whether a sampling moving image has been received from the factory terminal device 110 (step S1415). In the case where the sampling moving image has not been received (step S1415: No), the transaction management server 100 proceeds to the process of step S1417. On the other hand, in the case where the sampling moving image has been received (step S1415: Yes), the transaction management server 100 registers the sampling moving image in the transaction management DB 101 (step S1416). In addition, the sampling moving image is associated with the LOT number and registered in the transaction information indicated by the LOT number.

[0213] Next, the transaction management server 100 determines whether sampling has ended (step S1417). Specifically, the determination in step S1417 is to determine whether input information indicating the input has been received from the factory terminal device 110 by the factory terminal device 110 receiving an input indicating the end of sampling from the staff.

[0214] In the case where sampling has not ended (step S1417: No), the transaction management server 100 proceeds to the process of step S1419. On the other hand, in the case where sampling has ended (step S1417: Yes), the transaction management server 100 updates the status from "sampling" to "moisture value measuring" (step S1418).

[0215] Next, the transaction management server 100 determines whether there is an input of the moisture value (step S1419). Specifically, the determination in step S1419 is to determine whether input information related to the input has been received from the factory terminal device 110 by the factory terminal device 110 receiving an input of the moisture value from the staff. In the case where there is no input of the moisture value (step S1419: No), the transaction management server 100 proceeds to Figure 15 the process of step S1501. On the other hand, in the case where there is an input of the moisture value (step S1419: Yes), the status is updated from "moisture value measuring" to "analyzing" (step S1420).

[0216] Next, the transaction management server 100 determines whether there is an input of the analysis value (step S1501). Specifically, the determination in step S1501 is to determine whether the input information related to the input has been received from the factory terminal device 110 by accepting the input of the analysis value from the staff by the factory terminal device 110. In the case where there is no input of the analysis value (step S1501: No), the transaction management server 100 proceeds to the process of step S1503. On the other hand, in the case where there is an input of the analysis value (step S1501: Yes), the status is updated from "analyzing" to "analysis value determined" (step S1502).

[0217] Next, the transaction management server 100 determines whether there is an input of the re-analysis value (step S1503). Specifically, the determination in step S1503 is to determine whether the input information related to the input has been received from the factory terminal device 110 by accepting the input of the re-analysis value from the staff by the factory terminal device 110. In the case where there is no input of the re-analysis value (step S1503: No), the transaction management server 100 proceeds to the process of step S1505. On the other hand, in the case where there is an input of the re-analysis value (step S1503: Yes), the status is updated from "analysis value determined" to "re-analysis value determined" (step S1504).

[0218] Next, the transaction management server 100 determines whether there is an input of the re-re-analysis value (step S1505). Specifically, the determination in step S1505 is to determine whether the input information related to the input has been received from the factory terminal device 110 by accepting the input of the re-re-analysis value from the staff by the factory terminal device 110. In the case where there is no input of the re-re-analysis value (step S1505: No), the transaction management server 100 proceeds to the process of step S1507. On the other hand, in the case where there is an input of the re-re-analysis value (step S1505: Yes), the status is updated from "re-analysis value determined" to "re-re-analysis value determined" (step S1506).

[0219] Next, the transaction management server 100 determines whether there is an input of acceptance cancellation (step S1507). Specifically, the determination in step S1507 is to determine whether, based on the response to the confirmation notice from the user, the input information related to the input has been received from the factory terminal device 110 by accepting the input of acceptance cancellation from the staff by the factory terminal device 110. In the case where there is no input of acceptance cancellation (step S1507: No), the transaction management server 100 proceeds to the process of step S1509. On the other hand, in the case where there is an input of acceptance cancellation (step S1507: Yes), the status is updated from the current status to the "acceptance cancelled" status (step S1508).

[0220] Next, the transaction management server 100 determines whether there is an input for estimated payment (step S1509). Specifically, the determination in step S1509 is to determine whether it has received the input information related to the input by receiving the input for estimated payment from the staff by the factory terminal device 110 from the factory terminal device 110.

[0221] Estimated payment is to make an estimated payment of the equivalent remuneration based on the estimated information from the user before the evaluation process is completed.

[0222] In the case where there is no input for estimated payment (step S1509: No), the transaction management server 100 proceeds to the process of step S1511. On the other hand, in the case where there is an input for estimated payment (step S1509: Yes), it is updated from the current state to the "estimated payment" state (step S1510).

[0223] Next, the transaction management server 100 determines whether there is an input for final payment (step S1511). Specifically, the determination in step S1511 is to determine whether it has received the input information related to the input by receiving the input for final payment from the staff by the factory terminal device 110 from the factory terminal device 110.

[0224] In the case where estimated payment has been made, the final payment is the difference between the equivalent remuneration calculated based on the evaluation result and the estimated payment.

[0225] In the case where there is no input for final payment (step S1511: No), the transaction management server 100 proceeds to the process of step S1513. On the other hand, in the case where there is an input for final payment (step S1511: Yes), it is updated from the current state to the "final payment" state (step S1512).

[0226] Next, the transaction management server 100 determines whether there is an input for re - payment (step S1513). Specifically, the determination in step S1513 is to determine whether it has received the input information related to the input by receiving the input for re - payment from the staff by the factory terminal device 110 from the factory terminal device 110.

[0227] Re - payment is, for example, a payment generated for readjustment when the estimated analysis value based on the user is inconsistent with the actual analysis value in the recycling factory.

[0228] In the case where there is no input for re - payment (step S1513: No), the transaction management server 100 proceeds to the process of step S1515. On the other hand, in the case where there is an input for re - payment (step S1513: Yes), it is updated from the current state to the "re - payment" state (step S1514).

[0229] Next, the transaction management server 100 determines whether there is an input for repeated payment (step S1515). Specifically, the determination in step S1515 is to determine whether it has received the input information related to this input by receiving the input for repeated payment from the staff by the factory terminal device 110 from the factory terminal device 110.

[0230] Repeated payment is, for example, a payment generated for repeated adjustment when the estimated analysis value based on the user is inconsistent with the actual analysis value in the recycling factory.

[0231] In the case where there is no input for repeated payment (step S1515: No), the transaction management server 100 proceeds to the process of step S1517. On the other hand, in the case where there is an input for repeated payment (step S1515: Yes), the state is updated from the current state to the "repeated payment" state (step S1516).

[0232] Next, the transaction management server 100 determines whether there is an entrusted input (step S1517). Specifically, the determination in step S1517 is to determine whether it has received the input information related to this input by receiving the entrusted input from the staff by the factory terminal device 110 from the factory terminal device 110. In the case where there is no entrusted input (step S1517: No), the transaction management server 100 ends a series of processes. On the other hand, in the case where there is an entrusted input (step S1517: Yes), the state is updated from the current state to the "entrusted" state (step S1518), and a series of processes are ended.

[0233] (An example of the process related to the transmission of screen information performed by the transaction management server 100)

[0234] Figure 16 It is a flowchart showing an example of the process related to the transmission of screen information performed by the transaction management server 100. In addition, Figure 16 the process shown is a process that is regularly started in the transaction management server 100 (at very short time intervals). In Figure 16 this, the transaction management server 100 determines whether it has received a browsing request (step S1601). In the case where it has not received a browsing request (step S1601: No), the transaction management server 100 ends a series of processes.

[0235] On the other hand, in the case where a browsing request is received (step S1601: Yes), the transaction management server 100 determines whether the request source of the browsing request is the user terminal device 120 (step S1602). In the case where the request source of the browsing request is the user terminal device 120 (step S1602: Yes), the transaction management server 100 extracts the transaction information of the user according to the user ID included in the browsing request (step S1603). Then, the transaction management server 100 sends the screen information including only the extracted transaction information to the user terminal device 120 (step S1604), and ends a series of processes.

[0236] On the other hand, in step S1602, in the case where the request source of the browsing request is not the user terminal device 120 (step S1602: No), that is, in the case where the request source of the browsing request is the factory terminal device 110, the transaction management server 100 sends the screen information including all transaction information to the factory terminal device 110 (step S1605), and ends a series of processes.

[0237] As described above, the transaction management server 100 according to the present embodiment updates the status information corresponding to each process based on the progress information (input information) received from the staff in each process including the content evaluation process, and sends the screen information including the status information to the user terminal device according to the browsing request from the user terminal device. Thus, in the transaction related to the recycled raw material, the status can be notified to the user. Therefore, the user can grasp the current status. Therefore, the user can clarify the processes of the content evaluation process. Therefore, according to the present embodiment, the clarification of the transaction related to the recycled raw material can be realized.

[0238] Moreover, the transaction management server 100 according to the present embodiment updates the status information according to the evaluation results obtained in each evaluation process such as the wet weight, moisture value, and component value. Thus, the status information can be updated according to the input of the evaluation results from the staff. Therefore, the status information can be updated simply and accurately.

[0239] Moreover, the transaction management server 100 according to the present embodiment sends the screen information including the evaluation results in the evaluation process to the user terminal device 120 according to the browsing request from the user terminal device 120. Thus, the user can confirm the evaluation results of each evaluation process. Therefore, the user can clarify the evaluation process.

[0240] Moreover, the transaction management server 100 according to the present embodiment sends to the user terminal device 120 the estimated information 521 specified by the user (reference Figure 5Confirmation notice of the deviation between the input information entered by the staff. Thus, when there is a deviation between the user's estimate and the factory's opinion, by sending a confirmation notice, consent or rejection regarding the deviation can be obtained from the user. Therefore, inconsistencies between the user and the recycling factory can be suppressed, and the reliability of the transaction can be improved. Also, since the user can quickly confirm the deviation, the transaction can be expedited.

[0241] Moreover, the transaction management server 100 according to this embodiment sends a confirmation notice of the deviation between the measurement result based on the wet weight and the estimated weight predicted by the user to the user terminal device 120. Thus, when there is a deviation between the estimated weight and the measurement result, through the confirmation notice, the user can confirm the deviation related to the measurement, and consent or rejection regarding the deviation can be obtained from the user. Therefore, inconsistencies between the user and the recycling factory can be suppressed, and the reliability of the transaction can be improved. Also, since the user can quickly confirm the deviation related to the measurement, delays in the processes after measurement can be suppressed, thereby expediting the transaction.

[0242] Moreover, the transaction management server 100 according to this embodiment sends a confirmation notice of the deviation between the sampling method specified by the user and the sampling method specified by the staff to the user terminal device 120. Thus, when there is a deviation between the two sampling methods, through the confirmation notice, the deviation related to the sampling method can be confirmed, and consent or rejection regarding the deviation can be obtained from the user. Therefore, inconsistencies between the user and the recycling factory can be suppressed, and the reliability of the transaction can be improved. Also, since the user can quickly confirm the deviation related to the sampling method, delays in the processes after the sampling process can be suppressed, thereby expediting the transaction.

[0243] Moreover, the transaction management server 100 according to this embodiment sends screen information including video data (sampling moving images) of the recycled raw material taken by the staff in response to a browsing request from the user terminal device 120. Thus, the sampling process can be visualized through the sampling moving images 831. Therefore, the user can confirm the sampling process through the sampling moving images 831.

[0244] (Modification example of the embodiment)

[0245] Hereinafter, modification examples of the embodiment will be described. In addition, in each of the following modification examples, descriptions of what has been already described in the above embodiment will be appropriately omitted. In the modification example, an example of visualizing the status of the opening work of the recycled raw material received in the recycling factory will be described.

[0246] Recycled raw materials are transported into the recycling plant in various ways of transportation. The transportation methods are, for example, the method of being directly contained in a container of a transport vehicle or the method of being bagged in a Flexible Container Bag. If the metering is completed, the transported recycled raw materials are unsealed. That is, the unsealing work is carried out in the state of "metered / under inspection" after "arrived / awaiting metering". The unsealing work is carried out in batch units.

[0247] Figure 17A It is a diagram showing the situation when unsealing recycled raw materials from a container of a transport vehicle. As Figure 17A shown, the transport vehicle 1711 is equipped with a container 1712. On the container 1712, for example, there is marked the identification 1712a of the transport company (such as "○× Transportation") that the user knows through entrusting transportation, etc. The recycled raw materials 1713 are contained in the container 1712 in their original state.

[0248] The transport vehicle 1711 unseals the container 1712 in the unsealing area 1714 within the recycling plant. The unsealing area 1714 includes a plurality of placement areas 1716. The plurality of placement areas 1716 are areas where the recycled raw materials 1713 of each user can be placed respectively. When the transport vehicle 1711 arrives at the unsealing area 1714 within the recycling plant, in the specified placement area 1716, the container 1712 is opened and tilted according to the operation of the staff 1715. As a result, the recycled raw materials 1713 in the container 1712 are discharged into the specified placement area within the unsealing area 1714.

[0249] Figure 17B It is a diagram showing the situation when unsealing raw materials bagged in a flexible container bag. As Figure 17B shown, the flexible container bag 1721 is transported to the unsealing area 1714 by a forklift 1722. On the flexible container bag 1721, there is marked a specified flexible container bag number 1721a (such as "S123") that the user knows through bundling, etc. The flexible container bag number 1721a has a corresponding relationship with the batch number.

[0250] The forklift 1722 moves to the specified placement area 1716 within the unsealing area 1714 and unseals the flexible container bag 1721. Specifically, in the specified placement area 1716, if the staff 1715 cuts a part of the flexible container bag 1721 with a tool, etc., the recycled raw materials 1713 in the flexible container bag 1721 are discharged into the specified placement area 1716. Figure 17A and Figure 17B The situation during unsealing shown is photographed by a specified camera device.

[0251] Next, an example of the setting of the camera device will be described.

[0252] Figure 18 This is a diagram showing an example of the installation of imaging devices within the opening area 1714. As Figure 18 shown, the imaging devices 1800 are, for example, multiple fixed-point cameras. The imaging devices 1800 are arranged corresponding to multiple placement areas 1716 (1716a to 1716f) within the opening area 1714, and, for example, the same number as the number of placement areas 1716 (for example, 6) are arranged. The images captured by the imaging devices 1800 (hereinafter referred to as "opening images") are, for example, moving images. The imaging devices 1800 capture a series of actions from when the transport vehicle 1711 or the forklift 1722 enters the opening area 1714 until the recycled raw material 1713 is discharged into the opening area 1714.

[0253] For example, among the multiple placement areas 1716, imaging buttons 1801 for activating the corresponding imaging devices 1800 are arranged on walls or columns, etc. For example, the worker 1715 performing the opening operation in the placement area 1716a presses the imaging button 1801 corresponding to the placement area 1716a before the opening operation. Thereby, the imaging device 1800 corresponding to this placement area 1716 starts capturing the opening image. When the opening operation is completed, the worker 1715 presses the imaging button 1801 again. Thereby, the imaging device 1800 ends the capture of the opening image.

[0254] In addition, the imaging devices 1800 can change the imaging direction or zoom in with a zoom lens. Also, multiple imaging devices 1800 can be arranged at different positions for one placement area 1716. In this case, it is only necessary to capture the opening image from multiple angles by the multiple imaging devices 1800.

[0255] Moreover, the number of imaging devices 1800 arranged within the opening area 1714 may not be the same as the number of placement areas 1716. For example, it can also be set to a number less than the number of placement areas 1716. In this case, in order to capture each of the multiple placement areas 1716, the imaging devices 1800 change the imaging direction or zoom in with a zoom lens. When the worker 1715 presses the imaging button 1801 corresponding to the placement area 1716, the imaging device 1800 determines the placement area 1716 indicated by the imaging button 1801, changes its orientation towards the determined placement area 1716, and captures an enlarged image. Thus, it is also possible to capture the opening image within the placement area 1716.

[0256] In addition, when the imaging button 1801 is pressed and the imaging device 1800 is capturing an unsealing image of another placement area 1716, a notification indicating the intention to wait for imaging can be made. This notification can also be made by sound configured within the unsealing area 1714 or a display unit (image or lamp) configured on a wall surface or the like. Moreover, the imaging device 1800 is not limited to a fixed-point camera and can be a camera (e.g., a smartphone) held by a staff member. Also, the unsealing image is not limited to a moving image and can be a still image.

[0257] The captured unsealing image is associated with a date and time and stored. The unsealing image is sent to the transaction management server 100 at a specified timing and stored in the transaction management DB 101. Also, the transaction management server 100 sends the unsealing image to the user terminal device 120 according to a browsing request from the user.

[0258] Figure 19 It is an explanatory diagram showing an example of a browsing screen including an unsealing image. Figure 19 The browsing screen 1900 shown is different from Figure 8 the browsing screen 800 shown in that, in the imaging data area 830, in addition to the raw material image data 731 and the sampled moving image 831, an unsealing image 1901 is also displayed. The unsealing image 1901 can be a moving image directly played on the browsing screen 1900 or an icon for receiving moving image playback.

[0259] The user can confirm the transport company logo 1712a (e.g., "○× Transportation") or the flexible intermediate bulk container number 1721a (e.g., "S123") through the unsealing image 1901. Thereby, the user can simply confirm that their recycled raw material has been properly unsealed.

[0260] As described above, the transaction management server 100 according to Modification Example 1 registers the captured unsealing image in the transaction management DB 101 and sends screen information including the unsealing image to the user terminal device 120 according to a browsing request from the user terminal device 120. Thereby, the unsealing work can be visualized, and thus the reliability related to the transaction of recycled raw materials can be further improved.

[0261] In addition, all or part of each function (input / output, storage, processing) in the transaction management server 100 described above can be implemented in other devices different from the devices described as the execution entities of these functions. Specifically, in the above description, a structure in which the transaction management server 100 includes an input information acquisition unit 601, an update unit 602, a transmission unit 603, an extraction unit 604, and an estimated information acquisition unit 605 has been described. However, all or part of these functional units can be included in other computer devices. For example, all or part of these functional units can be included in the factory terminal device 110 or can be included in other computer devices. Moreover, the computer devices having these functional units are not limited to multiple ones and can be one. For example, all of these functional units can be included in one computer device.

[0262] In addition, the embodiments have been described, but the specific structure is not limited to the above embodiments and also includes designs and the like within the scope not departing from the gist of the present invention.

[0263] Processing can be performed by storing a program for implementing the functions of the devices and the like (e.g., the transaction management server 100, the factory terminal device 110, the user terminal device 120) related to the above-described embodiments in a computer-readable storage medium, reading the program stored in this storage medium into a computer system, and executing it. In addition, the "computer system" mentioned here can include a hardware such as an operating system (OS: Operating System) or peripheral devices. Moreover, the "computer-readable storage medium" refers to a writable non-volatile memory such as a USB (Universal Serial Bus) flash drive, an SSD (Solid State Drive), a floppy disk, an optical disk, a ROM (Read Only Memory), a flash memory, a portable medium such as a DVD (Digital Versatile Disc), or a storage device such as a hard disk built in the computer system.

[0264] Furthermore, the "computer-readable storage medium" also includes the following storage media: a volatile memory (e.g., DRAM (Dynamic Random Access Memory)) inside an information processing device or a computer system serving as a client when a program is sent via a network such as the Internet or a communication line such as a telephone line, which holds the program for a certain period of time. And the above program can be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the "transmission medium" for transmitting the program refers to a medium having a function of transmitting information such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. And the above program can be used to implement a part of the above functions. Moreover, the above program can be a program that can be combined with a program already stored in a computer system to implement the above functions, a so-called differential file (differential program).
