[0063] In this embodiment, the recovery information is described as including recovery method information indicating a method for recovering construction reuse materials (for example, a specific method for removing construction reuse materials from a structure), recovery cost information indicating the cost required for recovering construction reuse materials, recovery emission information indicating the amount of carbon dioxide emitted during the recovery of construction reuse materials, and value information indicating the value of construction reuse materials (for example, the historical value and / or cultural value of construction reuse materials).

[0064] This type of recovery information allows suppliers to be provided with information on recovery methods, recovery costs, recovered volume, and value, enabling effective support for the recovery of construction reuse materials.

[0065] However, this is not limited to the above; for example, the recovery information may include only one, two, or three of the following: recovery method information, recovery cost information, recovery amount information, or value information.

[0066] (Configuration - Transaction support device - Transaction support side control unit - Third supply unit) The third providing unit 32d is a third providing means that, when the target image TI is provided by the first providing unit 32a or when the transaction request information is acquired by the acquisition unit 32b, provides the demand-side device 20 with value information indicating the value of the construction reuse material corresponding to the target image TI or the transaction request information, estimated price information indicating the estimated price of the construction reuse material (in this embodiment, the estimated bid price at auction), and / or recovery emission information indicating the amount of carbon dioxide emitted when the construction reuse material is recovered.

[0067] (Configuration - Transaction support device - Transaction support side storage unit) The transaction support side storage unit 33 is a transaction support side storage means that records programs and various data necessary for the operation of the transaction support device 30, and as shown in Figure 4, it includes a target image database (hereinafter referred to as "DB") 33a and a provision DB 33b.

[0083] (Transaction support processing) Next, we will describe the transaction support processing performed by the supply-side control unit 15 of the supply-side device 10, the demand-side control unit 25 of the demand-side device 20, and the transaction support-side control unit 32 of the transaction support device 30, which are configured as described above.

[0084] In the following explanation, the step will be abbreviated as "S" in the description of each process shown in Figures 7 to 9.

[0085] (Transaction Support Processing - Preface) Transaction support processing is a process designed to support transactions involving reused construction materials.

[0086] The timing of executing this transaction support process is arbitrary, but in this embodiment, it will be described as being started after the power to the supply-side device 10, the demand-side device 20, and the transaction support device 30 is turned on.

[0087] In this embodiment, although the processing system 1 includes multiple supply-side devices 10 and multiple demand-side devices 20, the content of the transaction support processing performed by these supply-side devices 10 and demand-side devices 20 is identical. Therefore, the following will describe the transaction support processing performed by the supply-side device 10 (hereinafter referred to as the "target supply-side device"), the demand-side device 20 (hereinafter referred to as the "target demand-side device"), and the transaction support device 30.

[0088] (Transaction support processing - Processing details) When the transaction support process is activated, as shown in Figure 7, the demand-side control unit 25 of the target demand-side device in SA1 determines whether or not the transaction timing has arrived.

[0089] Here, "transaction timing" refers to the timing at which a user who possesses the target demand-side equipment conducts a transaction involving the reuse of construction materials.

[0090] Furthermore, while the method for determining whether or not this transaction timing has arrived is arbitrary, in this embodiment, the determination is made based on whether or not the target demand-side device is accessing a dedicated website for trading construction reuse materials (hereinafter referred to as the "dedicated trading website") using a desired browser or application installed on the target demand-side device.

[0091] Here, if the target demand-side equipment is accessing the trading website, it is determined that the trading timing has arrived; if the target demand-side equipment is not accessing the trading website, it is determined that the trading timing has not arrived.

[0092] The demand-side control unit 25 of the target demand-side device then waits until it is determined that a transaction timing has arrived (SA1, No), and if it is determined that a transaction timing has arrived (SA1, Yes), it proceeds to SA2.

[0093] In SA2, the demand-side control unit 25 of the target demand-side device displays a dedicated trading website via the demand-side output unit 23.

[0094] The method of displaying this trading-dedicated website is optional, but in this embodiment, the various screens of the trading-dedicated website (specifically, the search screen Da, the first trading screen Db, and the second trading screen Dc, etc., described below) are displayed on the screen of the demand-side output unit 23 until the processing of SA8 described below is completed.

[0095] Specifically, from the processing of SA2 until the completion of the processing of SA5 described later, a search screen Da for searching for construction reuse materials that may be subject to transaction is displayed on the screen of the demand-side output unit 23.

[0096] Here, the specific configuration of the search screen Da is arbitrary, but in this embodiment, as shown in Figure 10, the search screen Da has a search word input box Da1, a target image group selection screen Da2, a checkbox for selecting search conditions Da3, a checkbox for selecting hashtags Da4, and a search confirmation button Da5, and these are displayed.

[0097] However, the system is not limited to this; for example, it may have only one, two, or three of the following: a search word input box Da1, a target image group selection screen Da2, a search condition selection checkbox Da3, or a hashtag selection checkbox Da4.

[0098] Of these, the search word input box Da1 is an input box for entering search word information (text information in this embodiment) that indicates search words related to construction reuse materials, which are used when searching for construction reuse materials. As shown in Figure 10, it is located at the upper part of the search screen Da.

[0099] Furthermore, the target image group selection screen Da2 is a selection screen for selecting target image group information Da6 (in this embodiment, image information including text information) used when searching for construction reuse materials. As shown in Figure 10, this target image group selection screen Da2 is located below the search word input box Da1 on the search screen Da.

[0100] Furthermore, the search condition selection checkbox Da3 is a selection checkbox for selecting information indicating the search conditions used when searching for reused construction materials (in this embodiment, text information (in Figure 10, "prioritize early acquisition," "prioritize high price," "prioritize oldest age," "prioritize construction material," etc.). Hereinafter referred to as "search condition information"). As shown in Figure 10, multiple search condition selection checkboxes Da3 are arranged below the target image group selection screen Da2 on the search screen Da. In addition, each of the multiple search condition selection checkboxes Da3 is positioned near the corresponding search condition information among the multiple search condition information items arranged side by side along the left-right direction of the search screen Da.

[0101] Furthermore, the hashtag selection checkbox Da4 is a checkbox for selecting hashtags used when searching for reused construction materials, and is used to select information indicating hashtags related to reused construction materials (in this embodiment, text information (in Figure 10, "#Showa Roman", "#Handmade", "#One-of-a-kind", "#Construction Site", etc.). Hereinafter referred to as "hashtag information"). As shown in Figure 10, multiple hashtag selection checkboxes Da4 are arranged below the search condition selection checkboxes Da3 on the search screen Da. In addition, each of the multiple hashtag selection checkboxes Da4 is positioned near the corresponding hashtag information among the multiple hashtag information items arranged side by side along the left-right direction of the search screen Da.

[0102] Furthermore, the search confirmation button Da5 is a confirmation button used to confirm the input of search word information in the search word input box Da1, the selection of target image group information on the target image group selection screen Da2, the selection of search condition information in the search condition selection checkbox Da3, or the selection of hashtag information in the hashtag selection checkbox Da4. As shown in Figure 10, this search confirmation button Da5 is located below the hashtag selection checkbox Da4 on the search screen Da.

[0103] Returning to Figure 7, in SA3, the demand-side control unit 25 of the target demand-side device determines whether or not the acquisition timing has arrived.

[0104] Here, "acquisition timing" refers to the timing at which the target image TI corresponding to the information determined by the search confirmation button Da5 on the search screen Da displayed in SA2 (specifically, search word information, target image group information, search condition information, and hashtag information) is acquired.

[0105] Furthermore, while the method for determining whether or not this acquisition timing has arrived is arbitrary, in this embodiment, the determination is made based on whether or not an operation input (for example, a touch operation input) of the search confirmation button Da5 has been received after the search word information has been entered into the search word input box Da1 on the search screen Da displayed in SA2, the target image group information has been selected on the target image group selection screen Da2, the search condition information has been selected in the search condition selection checkbox Da3, and / or the hashtag information has been selected in the hashtag selection checkbox Da4 (in this embodiment, only one of these pieces of information will be selected).

[0106] If the above search confirmation button Da5 input is received, it is determined that the acquisition timing has arrived. If the above search confirmation button Da5 input is not received, it is determined that the acquisition timing has not arrived.

[0107] The demand-side control unit 25 of the target demand-side device then waits until it is determined that the acquisition timing has arrived (SA3, No), and if it is determined that the acquisition timing has arrived (SA3, Yes), it proceeds to SA4. If the operation input of the search decision button Da5 is not accepted even after a predetermined time has elapsed, the demand-side control unit 25 of the target demand-side device may proceed to SA1.

[0108] In SA4, the demand-side control unit 25 of the target demand-side device causes the demand-side communication unit 21 to transmit target image request information to the transaction support device 30.

[0109] Here, "target image request information" refers to information for requesting a target image TI from the transaction support device 30. In this embodiment, this target image request information is described as information that includes information determined by the search decision button Da5 when the operation input of the search decision button Da5 is received in SA3 (specifically, one of the following: search word information, target image group information, search condition information, or hashtag information).

[0110] Furthermore, as shown in Figure 8, in SB1, the transaction support control unit 32 of the transaction support device 30 determines whether or not the target image request information transmitted via SA4 has been received by the transaction support communication unit 31.

[0111] Then, the transaction support control unit 32 of the transaction support device 30 waits until it is determined that the target image request information has been received (SB1, No), and when it is determined that the target image request information has been received (SB1, Yes), it proceeds to SB2.

[0112] In SB2, the first supply unit 32a of the transaction support device 30 provides at least one target image TI corresponding to the target image request information received in SB1 to the target demand-side device via the transaction support-side communication unit 31.

[0113] The method for providing this target image TI is optional, but in this embodiment, it is provided as follows.

[0114] In other words, while referring to the information stored in the target image DB33a and / or the provision DB33b, the system extracts target image TI from the target image TI stored in the target image DB33a that match the information included in the target image request information (specifically, search word information, target image group information, search condition information, and hashtag information). Then, the system provides the extracted target image TI by transmitting it via the transaction support communication unit 31.

[0115] Furthermore, while the method for extracting the target image TI is arbitrary, in this embodiment, from the viewpoint of extracting the optimal target image TI, it is extracted using a method corresponding to the information contained in the target image request information.

[0116] Specifically, if the target image request information includes search word information, the system identifies information containing the search word information from the target image group information, construction reuse material type information, and construction reuse material details stored in the target image DB33a. Then, from the target image TI stored in the target image DB33a, the target image TI associated with the identified information is extracted as the target image TI to be extracted.

[0117] Alternatively, information containing the above search word information is identified from the construction reuse material type information, value information, and estimated price information stored in the provided DB33b, and then construction reuse material identification information associated with the identified information is identified. Then, from the target image TI stored in the target image DB33a, the target image TI associated with the identified construction reuse material identification information is extracted as the target image TI to be extracted.

[0118] Furthermore, if the target image request information includes target image group information, the target image TI (specifically, multiple target image TIs) associated with the target image group information are extracted from the target image TI stored in the target image DB33a as the target image TI to be extracted.

[0119] Furthermore, if the target image request information includes search condition information, information matching the search conditions of the search condition information (for example, "prioritizing early acquisition date") is identified from the construction reuse material type information and / or construction reuse material details information stored in the target image DB33a. Then, from the target image TI stored in the target image DB33a, the target image TI associated with the identified information is extracted as the target image TI to be extracted.

[0120] Alternatively, information matching the search criteria of the above search criteria information (e.g., "prioritize high price") is identified from the construction reuse material type information, value information, and / or estimated price information stored in the provided DB33b, and then the construction reuse material identification information associated with the identified information is identified. Then, from the target image TI stored in the target image DB33a, the target image TI associated with the identified construction reuse material identification information is extracted as the target image TI to be extracted.

[0121] Furthermore, if the target image request information includes hashtag information, information associated with that hashtag information (e.g., text information) is identified from the information posted on social networking services (SNS). Next, information containing the identified information is identified from the target image group information, construction reuse material type information, and / or construction reuse material details stored in the target image DB33a (or, after identifying information containing the identified information from the construction reuse material type information, value information, and / or estimated price information stored in the provision DB33b, construction reuse material identification information associated with that identified information is identified). Then, from the target image TI stored in the target image DB33a, the target image TI associated with the information identified from the target image DB33a (or the construction reuse material identification information identified from the provision DB33b) is extracted as the target image TI to be extracted.

[0122] In SB3, the third supply unit 32d of the transaction support device 30 provides the target demand-side device with value information, estimated price information, recovered / discharged waste information, construction reuse material type information, and / or construction reuse material identification information related to the target image TI provided in SB2, via the transaction support-side communication unit 31. Specifically, the value information, estimated price information, recovered / discharged waste information, construction reuse material type information, and construction reuse material identification information are provided almost simultaneously with the processing of SB3 (i.e., when the target image TI is provided by the first supply unit 32a of the transaction support device 30).

[0123] The method for providing value information, estimated price information, recovered waste information, construction reuse material type information, and construction reuse material identification information is optional, but in this embodiment, they are provided as follows.

[0124] Specifically, first, the construction reuse material identification information stored in the target image DB33a is identified as being associated with the target image TI provided by SB2. Next, the value information, estimated price information, recovered / discharged amount information, and construction reuse material type information stored in the provision DB33b are extracted as being associated with the identified construction reuse material identification information. Then, the transaction support side communication unit 31 provides the extracted value information, estimated price information, recovered / discharged amount information, and construction reuse material type information, along with the identified construction reuse material identification information, by transmitting them to the target demand side device.

[0125] Furthermore, in the processing of SA6 described later, when the value information, estimated price information, recovered waste information, construction reuse material type information, and construction reuse material identification information provided by SB3 are displayed on the demand-side output unit 23, it is preferable that this value information, estimated price information, recovered waste information, construction reuse material type information, and construction reuse material identification information are displayed in association with the target image TI provided by SB2 (for example, as shown in Figures 12 and 13, the value information, etc., is displayed near a portion CM (hereinafter referred to as "construction reuse material portion CM") corresponding to the construction reuse material included in the target image TI). Therefore, in this embodiment, display control command information for displaying the value information, estimated price information, recovered waste information, construction reuse material type information, and construction reuse material identification information in association with the target image TI provided by SB2 is provided to the target demand-side device along with the provision of this value information, estimated price information, recovered waste information, construction reuse material type information, and construction reuse material identification information.

[0126] However, this is not limited to this case; for example, if the target image TI and value information are simply displayed side by side, the provision of display control command information may be omitted.

[0127] This SB3 processing allows us to provide consumers with value information, estimated price information, and recovery / disposal information. It also makes it easier for consumers to understand the details of the construction reuse materials related to the target image TI provided in SB2, thus facilitating the trading of construction reuse materials that meet consumers' needs.

[0128] Returning to Figure 7, in SA5, the demand-side control unit 25 of the target demand-side device determines whether the target image TI provided in SB2, and the value information, estimated price information, recovered waste information, construction reuse material type information, construction reuse material identification information, and display control command information provided in SB3 have been received by the demand-side communication unit 21.

[0129] Then, the demand-side control unit 25 of the target demand-side device waits until it is determined that the target image TI etc. has been received (SA5, No), and when it is determined that the target image TI etc. has been received (SA5, Yes), it proceeds to SA6.

[0130] In SA6, the demand-side control unit 25 of the target demand-side device displays the target image TI, value information, estimated price information, recovered / discharged amount information, construction reuse material type information, and / or construction reuse material identification information received in SA5 via the demand-side output unit 23. Specifically, it displays the target image TI, value information, estimated price information, recovered / discharged amount information, construction reuse material type information, and construction reuse material identification information received in SA5 until the processing of SA8, which will be described later, is completed.

[0131] The method for displaying the target image TI, etc., is optional, but in this embodiment, it is displayed as follows.

[0132] In other words, if the target image TI received by SA5 is a target image TI extracted by SB2 based on the target image group information (specifically, multiple target image TIs), then, as shown in Figure 11, the demand-side output unit 23 displays a first transaction screen Db that displays multiple target image TIs in parallel, instead of the search screen Da.

[0133] In this case, for example, as shown in Figure 11, the first transaction screen Db may display multiple target images TI in parallel such that the placement positions of the construction reuse material portions CM contained in each of the multiple target images TI are the same as the placement relationships of the construction reuse materials in the actual structure.

[0134] This type of display allows consumers to understand the placement of reused construction materials in the multiple target images TI mentioned above within the actual structure, making it easier for them to grasp the condition of the reused construction materials.

[0135] However, this is not limited to this; for example, in the first transaction screen Db, multiple target images TI may be displayed side by side along the vertical and / or horizontal directions.

[0136] Next, if one of the multiple target images TI displayed on the first transaction screen Db is selected via the demand-side operation unit 22, the second transaction screen Dc, which displays only the selected target image TI, is displayed on the demand-side output unit 23's screen instead of the first transaction screen Db, as shown in Figure 12 or Figure 13. For example, the first transaction screen Db and the second transaction screen Dc may be switched by accepting a predetermined switching operation via the demand-side operation unit 22.

[0137] In this embodiment, when the selected target image TI is displayed on the second transaction screen Dc, as shown in Figure 12 or Figure 13, the value information, estimated price information, recovered waste amount information, construction reuse material type information, construction reuse material identification information, and composition information included in the target image TI are displayed in association with the construction reuse material portion CM included in the selected target image TI, based on the display control command information received by SA5. More specifically, the value information, etc., are displayed in a callout screen Dd that is displayed near the construction reuse material portion CM.

[0138] This type of display makes it easier for consumers to see the details of the construction reuse material related to the above-mentioned image TI, thereby making it easier for consumers to understand the details of the said construction reuse material.

[0139] However, this is not limited to this; for example, value information received by SA5 may be displayed at a location separate from the construction reuse material section CM mentioned above.

[0140] Furthermore, if the target image TI received by SA5 is one of several target image TIs extracted by SB2 based on search word information (or search condition information or hashtag information), the demand-side output unit 23 displays a first transaction screen (not shown) on its screen, instead of the search screen Da, which displays the multiple target image TIs in parallel along the vertical and / or horizontal directions. Subsequently, if one of the multiple target image TIs displayed on the first transaction screen Db is selected via the demand-side operation unit 22, the demand-side output unit 23 displays a second transaction screen Dc on its screen, instead of the first transaction screen Db, as shown in Figure 12 or Figure 13, which displays only the selected target image TI.

[0141] Furthermore, if the target image TI received by SA5 is one of the target image TIs extracted by SB2 based on search word information (or search condition information or hashtag information), then, as shown in Figure 12 or Figure 13, the demand-side output unit 23 displays a second transaction screen Dc that shows only the selected target image TI, instead of the search screen Da.

[0142] This SA6 processing allows the target image TI to be provided to the user, and the condition of the construction reuse material before collection can be understood.

[0143] Returning to Figure 7, in SA7, the demand-side control unit 25 of the target demand-side device determines whether or not the construction reuse material to be traded has been identified based on the target image TI displayed in SA6.

[0144] Furthermore, while the method for determining whether the above-mentioned construction reuse material has been identified is arbitrary, in this embodiment, the determination is made based on whether the construction reuse material portion CM included in the target image TI displayed in SA6, or the construction reuse material identification information displayed in association with the target image TI displayed in SA6, has been selected via the demand-side operation unit 22, or whether the input of construction reuse material identification information has been received via the demand-side operation unit 22.

[0145] Here, if the above-mentioned construction reuse material portion CM or the above-mentioned construction reuse material identification information is selected via the demand-side operation unit 22, or if the input of construction reuse material identification information is received via the demand-side operation unit 22, it is determined that the above-mentioned construction reuse material has been identified. On the other hand, if the above-mentioned construction reuse material portion CM or the above-mentioned construction reuse material identification information is not selected via the demand-side operation unit 22, and if the input of construction reuse material identification information is not received via the demand-side operation unit 22, it is determined that the above-mentioned construction reuse material has not been identified.

[0146] Then, in SA7, the demand-side control unit 25 of the target demand-side device waits until the above-mentioned construction reuse material is identified (SA7, No), and if it is determined that the above-mentioned construction reuse material has been identified (SA7, Yes), it proceeds to SA8.

[0147] In SA8, the demand-side control unit 25 of the target demand-side device transmits transaction request information via the demand-side communication unit 21. Subsequently, the demand-side control unit 25 of the target demand-side device transitions to SA1, and the processing from SA1 to SA8 is repeated in the same manner thereafter.

[0148] Furthermore, while the method of transmitting this transaction request information is optional, in this embodiment it will be transmitted as follows.

[0149] In other words, if a construction reuse material portion CM included in the target image TI is selected in SA7 via the demand-side operation unit 22, transaction request information including the target image TI is transmitted.

[0150] Furthermore, if construction reuse material identification information displayed in SA7 in association with the target image TI is selected via the demand-side operation unit 22, or if input of construction reuse material identification information is received via the demand-side operation unit 22, transaction request information including said construction reuse material identification information is transmitted.

[0151] Furthermore, as shown in Figure 8, in SB4, the acquisition unit 32b of the transaction support device 30 determines whether or not the transaction request information transmitted by SA8 has been acquired (received) via the transaction support side communication unit 31.

[0152] Then, the acquisition unit 32b of the transaction support device 30 waits until it is determined that the transaction request information has been acquired (SB4, No), and if it is determined that the transaction request information has been acquired (SB4, Yes), it proceeds to SB5.

[0153] In SB5, the second supply unit 32c of the transaction support device 30 generates recovery information.

[0154] The method for generating this recovery information is optional, but in this embodiment, it is generated as follows.

[0155] In other words, if the transaction request information received by SB4 includes the target image TI (i.e., the target image TI provided by the first provisioning unit 32a), recovery information is generated based on the target image TI.

[0156] For example, after transmitting the above-mentioned target image TI to an appraisal device (not shown) owned by an expert or engineer who appraises construction reuse materials, the appraisal device receives information on the recovery method, recovery cost, recovery volume, and value generated by the expert based on the above-mentioned target image TI. Then, information including the received recovery method, recovery cost, recovery volume, and value information, along with the above-mentioned target image TI, may be generated as recovery information.

[0157] Alternatively, the construction reuse material identification information associated with the target image TI is identified from the construction reuse material identification information stored in the target image DB33a. Next, the recovery method information, recovery cost information, recovery amount information, and value information associated with the identified construction reuse material identification information are extracted from the recovery method information, recovery cost information, recovery amount information, and value information stored in the provision DB33b. Then, information including the extracted recovery method information, recovery cost information, recovery amount information, and value information, and the target image TI or / or the construction reuse material identification information associated with the target image TI may be generated as recovery information.

[0158] Furthermore, if the transaction request information received by SB4 includes construction reuse material identification information, recovery information is generated based on the said construction reuse material identification information or the target image TI corresponding to the said construction reuse material identification information (i.e., the target image TI provided by the first provisioning unit 32a).

[0159] For example, from among the target image TIs stored in the target image DB33a, a target image TI associated with the above-mentioned construction reuse material identification information is identified. Next, after transmitting the identified target image TI to the appraisal device, the terminal device receives recovery method information, recovery cost information, recovery amount information, and value information generated by experts, etc., based on the target image TI. Then, information including the received recovery method information, recovery cost information, recovery amount information, and value information, and the above-mentioned construction reuse material identification information or / or the target image TI associated with said construction reuse material identification information may be generated as recovery information.

[0160] Alternatively, recovery method information, recovery cost information, recovery amount information, and value information associated with the above-mentioned construction reuse material identification information may be extracted from the recovery method information, recovery cost information, recovery amount information, and value information stored in the provided DB33b. Then, information including the extracted recovery method information, recovery cost information, recovery amount information, and value information, and the above-mentioned construction reuse material identification information or / or the target image TI associated with said construction reuse material identification information may be generated as recovery information.

[0161] By generating the collection information in the manner described above, it becomes possible to easily generate the information and simplify the effort required for its generation.

[0162] In SB6, the second providing unit 32c of the transaction support device 30 provides (transmits) the recovery information generated in SB5 to the target supply-side device (specifically, the target supply-side device owned by the supplier that supplies the construction reuse materials related to the transaction request information) via the transaction support-side communication unit 31. Subsequently, the transaction support-side control unit 32 of the transaction support device 30 moves to SB1 and repeats the processing from SB1 to SB6 in the same manner thereafter.

[0163] Furthermore, as shown in Figure 9, in SC1, the supply-side control unit 15 of the target supply-side device determines whether or not the recovery information provided by SB6 has been received by the supply-side communication unit 11.

[0164] The supply-side control unit 15 of the target supply-side device then waits until it is determined that the recovery information has been received (SC1, No), and if it is determined that the recovery information has been received (SC1, Yes), it proceeds to SC2.

[0165] In SC2, the supply-side control unit 15 of the target supply-side device displays the recovery information received in SC1 via the supply-side output unit 13.

[0166] The method of displaying this recovery information is optional, but in this embodiment, until the processing of SA8 described later is completed, the screen of the supply-side output unit 13 displays a recovery screen (not shown) that displays the recovery information received by SC1 (specifically, recovery cost information, recovery discharge information, value information, and construction reuse material identification information (or / and the target image TI associated with the construction reuse material identification information)) in parallel in the vertical and / or horizontal directions.

[0167] In SC3, the supply-side control unit 15 of the target supply-side device determines whether or not the timing to end the display of the recovery screen shown in SC2 (hereinafter referred to as the "end timing") has arrived.

[0168] The method for determining whether or not this termination timing has arrived is arbitrary, but in this embodiment, the determination is made based on whether or not a predetermined operation has been received via the supply-side operation unit 12, or whether or not a predetermined time (for example, 10 minutes) has elapsed since the processing of SC2 was completed.

[0169] If the above-mentioned predetermined operation is accepted, or if the above-mentioned predetermined time has elapsed, it is determined that the termination timing has arrived. If the above-mentioned predetermined operation is not accepted, or if the above-mentioned predetermined time has not elapsed, it is determined that the termination timing has not arrived.

[0170] Then, if the supply-side control unit 15 of the target supply-side device determines that the termination timing has not yet arrived (SC3, No), it repeats the processing of SC2 and SC3 until it determines that the termination timing has arrived. On the other hand, if it determines that the termination timing has arrived (SC3, Yes), it proceeds to SC1 and repeats the processing of SC1 to SC3 in the same manner thereafter.

[0171] Through the transaction support processing described above, collection information can be provided to suppliers, enabling support for the collection of reused construction materials. Furthermore, target images (TI) can be provided to consumers, allowing them to understand the condition of the reused construction materials before collection, even if they are located far from the structure. Therefore, it is possible to improve the tradability of reused construction materials.

[0172] (Effects of the embodiment) As described above, according to this embodiment, the system includes a first providing unit 32a that provides a target image TI to the demand-side device 20, an acquisition unit 32b that acquires transaction request information from the demand-side device 20, and a second providing unit 32c that provides recovery information to the supply-side device 10 when the transaction request information is acquired by the acquisition unit 32b. Therefore, recovery information can be provided to suppliers, and support can be provided for the recovery of construction reuse materials. Furthermore, the target image TI can be provided to the demander, allowing the demander to understand the condition of the construction reuse materials before recovery, even if they are located far from the structure. As a result, it is possible to improve the tradeability of construction reuse materials.

[0173] Furthermore, since the recovery information includes recovery method information, recovery cost information, recovery volume information, and / or value information indicating the value of the construction reuse material, it is possible to provide recovery method information, recovery cost information, recovery volume information, and value information to suppliers, thereby enabling effective support for the recovery of construction reuse material.

[0174] Furthermore, since the target image TI includes a 3D model image and information indicating the composition of the reused construction material, it becomes easier for consumers to understand the condition of the reused construction material related to the target image TI, thus facilitating transactions of reused construction material that meet the consumer's needs.

[0175] Furthermore, the second supply unit 32c generates recovery information based on the target image TI provided by the first supply unit 32a and provides the generated recovery information to the supply-side device 10. This makes it possible to easily generate recovery information and simplify the effort required for its generation.

[0176] Furthermore, the system includes a third providing unit 32d that provides value information, estimated price information, and / or recovered waste information to the demand-side device 20 when the target image TI is provided by the first providing unit 32a or when transaction request information is acquired by the acquisition unit 32b. This allows value information, estimated price information, and recovered waste information to be provided to the demander, making it easier for the demander to understand the details of the construction reuse material related to the target image TI, and thus facilitating transactions of construction reuse materials that meet the demander's needs.

[0177] [III] Modifications of the Embodiment While embodiments of the present invention have been described above, the specific configurations and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of ​​each invention described in the claims. Such modifications will be described below.

[0178] (Regarding the problems to be solved and the effects of the invention) First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above. The present invention may solve problems not described above, produce effects not described above, solve only some of the problems described above, or produce only some of the effects described above.

[0179] (Regarding decentralization and integration) Furthermore, the electrical components described above are functional concepts and do not necessarily need to be physically configured as shown in the diagram. In other words, the specific forms of distribution and integration of each part are not limited to those shown in the diagram, and all or part of them can be functionally or physically distributed or integrated in any unit according to various loads and usage conditions. For example, the trading support device 30 may be distributed among multiple devices configured to communicate with each other, with the trading support control unit 32 provided in some of these multiple devices and the trading support storage unit 33 provided in other parts of these multiple devices.

[0180] (Regarding shape, numerical values, structure, and time series) With regard to the components illustrated in the embodiments and drawings, their shapes, numerical values, or the interrelationships of the structure or time series of multiple components can be arbitrarily modified and improved within the scope of the technical concept of the present invention.

[0181] (Regarding structures) In the above embodiment, the structure was described as a building structure being demolished, such as an office building being demolished. However, it is not limited to this, and may be a building structure that is not being demolished, for example.

[0182] (Regarding supply-side equipment and demand-side equipment) In the above embodiment, the supply-side device 10 and the demand-side device 20 are each described as being composed of smartphones, but the invention is not limited to these, and may be composed of, for example, a tablet device, a stationary personal computer, or a laptop computer.

[0183] (Regarding trading support equipment) In the above embodiment, the transaction support device 30 was described as being composed of a cloud server, but it is not limited to this, and may be composed of, for example, a server device installed in a management facility.

[0184] Furthermore, although the above embodiment describes the transaction support device 30 as including a third supply unit 32d, it is not limited to this, and for example, the third supply unit 32d may be omitted. In this case, the processing of SB3 in the transaction support processing may also be omitted.

[0185] (Regarding the target image) In the above embodiment, the target image TI was described as including a 3D model image and configuration information, but it is not limited to this. For example, the target image TI may simply be an image generated based on an image of the target portion (for example, a 2D image, a 3D image, a 2D model image, or a 3D model image).

[0186] In this case, for example, the first supply unit 32a of the transaction support device 30 may extract an image corresponding to the construction reuse material and / or the dimensions of the said construction reuse material from the captured image, and provide the construction reuse material-related information, which is information indicating the extracted image and / or dimensions, to the demand-side device 20.

[0187] As an example, first, the first providing unit 32a of the transaction support device 30 automatically extracts the image corresponding to the construction reuse material included in the captured image and / or the dimensions of the said construction reuse material using a known image analysis method (for example, artificial intelligence, a similarity determination algorithm, or / or an image analysis method using a measurement method of a predetermined standard). Next, the extracted information is automatically registered (stored) as construction reuse material-related information in a predetermined database (not shown) provided in the transaction support side storage unit 33. Then, when a transaction of construction reuse material occurs, the construction reuse material-related information stored in the database may be provided to the demand side device 20 by transmitting it via the transaction support side communication unit 31.

[0188] This reduces the effort required to create information related to reused construction materials, and allows for the presentation of information on potentially tradeable reused construction materials to consumers, thereby further enhancing the tradeability of reused construction materials.

[0189] (Regarding transaction support processing) In the above embodiment, it was explained that the processing of SB3 is performed when the target image TI is provided by the first providing unit 32a of the transaction support device 30, but this is not limited to this. For example, it may be performed after the processing of SB4 (i.e., when the transaction request information is acquired by the acquisition unit 32b of the transaction support device 30).

[0190] Furthermore, in the above embodiment, it was explained that in the processing of SB5, the second providing unit 32c of the transaction support device 30 generates recovery information using information received from the appraisal device or information stored in the providing DB 33b, but this is not limited to this. For example, if the transaction request information received in SB4 includes a target image TI, the second providing unit 32c of the transaction support device 30 may use a known image analysis method to identify the installation state of the construction reuse material portion CM included in the target image TI, and while referring to known recovery method information obtained by a predetermined method, identify recovery method information corresponding to the identified installation state, and generate recovery information including the identified recovery method information. In this case, the providing DB 33b of the transaction support device 30 may be omitted.

[0191] (Regarding recall information) In the above embodiment, the recovery information was described as information including the target image TI or construction reuse material identification information. However, it is not limited to this, and for example, it may be information that does not include either the target image TI or the construction reuse material identification information.
