[Operation of wood management system]
Next, the operation of the wood management system of the present embodiment configured as described above will be described with reference to a flowchart and the like. In the following, (1) a registration stage for registering wood information, (2) a tag attachment stage for attaching the wireless IC tag 5 to wood, (3) a transportation stage for transporting wood, and (4) chip processing for wood. The description will be divided into a processing stage, (5) a shipping stage in which wood chips are shipped, and (6) a reporting stage in which various kinds of information related to woody biomass are reported.

(1) Registration stage In the registration stage, timber information related to felled timber is generated and registered in the timber information DB 13A. Specifically, the forestry business entity uses the forestry business entity terminal 2 to input information such as unit price and inventory amount included in the timber information. Here, the production area, tree species, forest age, coordinates, and the like may be obtained from the wireless IC tag 5 provided in the forest subsection to which the wood growing area belongs. Thereafter, the forestry business entity terminal 2 transmits the information and the image data of the wood to the management server 1. The management server 1 generates wood information based on the information received from the forestry business entity terminal 2 and registers it in the wood information DB 13A.

  Further, in the case of general timber or construction material, the handling company inputs information such as unit price and inventory amount of the general timber or construction material and image data to the information terminal. Thereafter, each piece of information and image information data is transmitted from the information terminal to the management server 1. The management server 1 generates wood information based on the information received from the information terminal and registers it in the wood information DB 13A.

  At this registration stage, since the FIT price is not fixed, the management server 1 puts a temporary value (hereinafter referred to as “temporary setting price”) in the wood information. Specifically, in the case of this embodiment, it is set at 32 yen for unused wood, 24 yen for general wood, and 13 yen for construction materials.

  The wood ID is numbered by the management server 1, and this is notified to a trader handling wood such as a forestry business entity. As a result, the wood ID is grasped in each trader handling the wood.

(2) Tag attachment stage The wireless IC tag 5 is attached to the wood whose wood information is registered as described above. The wood ID of the wood is written into the wireless IC tag 5 by the reader / writer. Each wireless IC tag 5 is given a unique tag ID in advance, and the tag ID and the wood ID are associated with each other and stored in the wireless IC tag 5. The tag ID is read from the wireless IC tag 5 by a reader / writer and transmitted to the management server 1 via the forestry business entity terminal 2 and the like. Receiving this, the management server 1 registers the tag ID in the wood information DB 13A. Thereby, also in the management server 1, tag ID and wood ID will be linked | related. The management server 1 reads out the wood information including the wood ID from the wood information DB 13A and transmits it to the forestry business entity terminal 2 and the like. Thereafter, the wood information is written into the wireless IC tag 5 by the reader / writer.

  When the wood to which the wireless IC tag 5 is attached is an unused material, a certificate proving that is issued by the forestry business entity. The certificate name and certificate ID issued in this way are written into the wireless IC tag 5 by the reader / writer. A certificate may be issued even when the wood to which the wireless IC tag 5 is attached is general wood. In this case, the certificate name and certificate ID are written in the wireless IC tag 5 in the same manner.

  When a certificate is issued as described above, an image of the certificate is transmitted to the management server 1 by the forestry business entity terminal 2 or the like. The management server 1 stores the image of the certificate transmitted in this way, and uses the image at the report stage described later. Note that certificate images issued in the following steps are also stored in the management server 1 in the same manner.

(3) Transport stage The wood to which the wireless IC tag 5 is attached as described above is transported to a processing facility for chip processing or a ground for temporary storage. At the time of transportation, information such as transportation ID, departure place, arrival place, weight of wood, carry-out date / time, and carry-in date / time is written to the wireless IC tag 5 by the reader / writer. Note that each piece of information and the tag ID of the wireless IC tag 5 are transmitted to the management server 1 by an information terminal used by a carrier that carries the goods, and the management server 1 that receives the information sends them to the transportation information DB 13B and the wireless tag. Predetermined information is registered in the information DB 13D.

  In this transportation stage, when the wood to which the wireless IC tag 5 is attached is separately managed, a certificate proving that is issued by the handling company. The certificate name and certificate ID issued in this way are written into the wireless IC tag 5 by the reader / writer.

(4) Processing Stage Wood that has arrived at the processing facility through the above-described transporting step is subjected to chip processing at the processing facility. During the chip processing, the processing ID, the processing date / time, the weight of the wood chip, the drying start date / time and the drying period are written into the wireless IC tag 5 by the reader / writer. Each piece of information and the tag ID of the wireless IC tag 5 are transmitted to the management server 1 by the processor terminal 3, and the management server 1 receiving the information transmits predetermined information to the processing information DB 13C and the wireless tag information DB 13D. Register.

  The wireless IC tag 5 manages the drying period required for the wood chip to be completely dry, and when the period elapsed from the drying start date and time reaches the drying period, the reader / writer and the processor terminal 3 are connected. To the management server 1. Thereby, the management server 1 can grasp that the wood chip managed by the wireless IC tag 5 has completely dried. Although details are not described here, drying for a predetermined period is performed before chip processing. As for the drying before chip processing, the wireless IC tag 5 can also manage the timer in the same manner as described above.

  In this processing stage, when the wood to which the wireless IC tag 5 is attached and the wood chip obtained from the wood are separately managed, a certificate proving that is issued by the processor. The certificate name and certificate ID issued in this way are written into the wireless IC tag 5 by the reader / writer.

  In the processing facility, there are both cases where chips are processed only for wood related to one wireless IC tag 5 and chips are processed collectively for wood related to a plurality of wireless IC tags 5. In the latter case, it is difficult to take correspondence between the wood chip and the wireless IC tag 5 after being formed into chips. Therefore, it is prohibited to chip-process different types of wood such as unused material and general wood, and only the same type of wood is chip-processed.

  In some cases, the product is shipped to the purchaser in the form of raw wood instead of wood chips. In that case, the process proceeds to the next shipping stage without going through the above-described processing stage.

(5) Shipment Stage Wood chips that have been processed by the above-described processing stage and have been completely dried are shipped to a purchaser who is a business operator of woody biomass power generation. When the purchase destination is confirmed, the management server 1 executes FIT price confirmation processing for confirming the FIT price as follows. Note that, as described above, wood may be shipped without chip processing, so the shipment object is wood chip or wood before chip processing. Hereinafter, these wood chips or wood before chip processing may be collectively referred to as “wood”.

  FIG. 10 is a flowchart showing a procedure of FIT price determination processing executed by the management server 1. First, the management server 1 acquires certificate information including the name and certificate ID of one or more certificates issued for the wood chip from the wireless IC tag 5 attached to the wood to be shipped (S101). ). Here, when the chips related to the plurality of wireless IC tags 5 are collectively processed at the above-described processing stage, the certificate information is acquired from each of the plurality of wireless IC tags 5. This certificate information may be acquired directly from the wireless IC tag 5 by a reader / writer connected to the management server 1, or may be acquired indirectly from the wireless IC tag 5 via another device. The certificate ID obtained in this way is stored in the certificate ID field 405 of the wireless tag information DB 13D.

  Next, based on the acquired certificate information, the management server 1 determines whether or not there are all certificates for maintaining the FIT price (hereinafter referred to as “temporary setting price”) temporarily set for the wood. Determine (S102). Specifically, if the timber is unused, whether there is a certificate that it is derived from thinned wood, etc., and that a separate management is being performed, and if the timber is general timber Whether or not there is a certificate of general woody biomass and a certificate that classification management is being performed is determined respectively. In addition, the code | symbol which shows what kind of certificate is contained in certificate ID, The management server 1 can determine the presence or absence of said certificate using the code | symbol.

  If the management server 1 determines in step S102 that all necessary certificates are present (YES in S102), the management server 1 determines that the type of the wood is that at the time of registration of the wood information, and temporarily sets the FIT price for the wood. A price is set (S103). In this case, since the temporary setting price is already stored in the FIT price field 111 of the wood information DB 13A, the management server 1 keeps the value of the FIT price field 111 unchanged. On the other hand, if it is determined in step S102 that there is no necessary certificate (NO in S102), the management server 1 determines that the wood type is construction material or similar wood, and the FIT price for the wood is the lowest. A price (13 yen in this embodiment) is set (S104). Specifically, the management server 1 changes the value of the FIT price field 111 to the lowest price.

  Next, the management server 1 determines whether or not the wood is an unused material (S105). If it is determined that the wood is not an unused material (NO in S105), the process proceeds to step S109 described later. On the other hand, when it determines with it being an unused material (it is YES at S105), the management server 1 determines whether the electric power generation scale of the supplier of the timber is 2,000 kW or more (S106).

  If the management server 1 determines in step S106 that the power generation scale of the purchaser is 2,000 kW or more (YES in S106), the management server 1 sets a provisional set price for the FIT price for the wood (S107). In this case, since 32 yen is already stored as a provisional price in the FIT price field 111 of the wood information DB 13A, the management server 1 leaves the value of the FIT price field 111 unchanged. On the other hand, when it is determined in step S106 that the power generation scale of the purchaser is less than 2,000 kW (NO in S106), the management server 1 sets the highest price (40 in the case of this embodiment) as the FIT price for the timber. Circle) is set (S108). Specifically, the management server 1 changes the value of the FIT price field 111 to the lowest price.

  Thereafter, the management server 1 stores the code indicating that the FIT price has been confirmed in the confirmation field 112, thereby updating the wood information DB 13A (S109). As a result, the FIT price of wood has been confirmed.

  In the present embodiment, the FIT price determination process is executed at the shipping stage, but the same process may be executed at other timings.

Conveyance information, processing information, RFID tag information, and forest information are also displayed in the same manner. By referring to the management screen 1001, the operator of each information terminal can check the outline of the wood, the FIT price, and the like. The management server 1 can also be browsed by displaying such a management screen 1001 on the display 15. Thereby, the related trader can grasp the information related to the history management of wood.

(6) Report stage After passing through the above stages, the wood biomass purchaser, who is a wood biomass power generation company, and the power company that purchases the power from the wood biomass power generation at various times, various kinds of wood biomass Information is reported. There are various forms of this report, such as mailing a paper medium on which these various types of information are printed, or providing electronic data with these various types of information attached to an e-mail. is assumed. Hereinafter, an example in which various types of information are provided on a website will be described.

  After the FIT price is confirmed, the management server 1 is a purchaser terminal 4 used by a purchaser of wood chips obtained from the wood and an electric power company that has concluded a power sale contract with the purchaser. A specific URL is notified to the electric power company terminal 6 to be used. When the purchasing company terminal 4 or the power company terminal 6 accesses the URL, the management server 1 provides information on the following report screen to the access source.

  FIG. 12 is a diagram illustrating an example of a report screen displayed on the display unit of the purchaser terminal 4 or the power company terminal 6. As shown in FIG. 12, this report screen 2001 displays the type of wood and the FIT price, and the wood ID of the wood that is the source of the purchased wood chip. In this display example, the origin of the wood chip is wood related to a plurality of wood IDs, and thus a plurality of wood IDs are shown. In the present embodiment, since the wood ID and the tag ID correspond one-to-one, a plurality of tag IDs may be displayed side by side instead of the wood ID. A detail button for displaying detailed information on the wood is provided next to the wood ID. When this detail button is clicked, information associated with the wood ID among the wood information, transport information, processing information, wireless tag information, forest information, and other information is displayed. In addition, an image acquired from the address stored in the image field 113 of the wood information DB 13A is displayed in the photo column. By referring to this report screen 2001, the purchaser of the wood chip or the person in charge of the electric power company can confirm the outline of the wood, the FIT price, and the like.

  As shown in FIG. 12, the report screen 2001 is provided with a button 2002 for displaying issued certificate information relating to issued certificates. When a purchaser of wood chips or a person in charge of an electric power company clicks this button 2002 using the input unit, the management server 1 provides information related to the issued certificate screen to the access source.

  FIG. 13 is a diagram illustrating an example of the issued certificate screen displayed on the display unit of the purchaser terminal 4 or the power company terminal 6. As shown in FIG. 13, the issued certificate screen 3001 displays the certificate name and certificate ID acquired by the management server 1 from the wireless IC tag 5. In addition, an image of the certificate stored in the management server 1 is displayed in the copy field. The purchaser of the wood chip or the person in charge of the power company can confirm the contents of the issued certificate by referring to the issued certificate screen 3001. When a plurality of certificates are issued for the wood, the issued certificate screen 3001 is configured so that information related to all the certificates can be displayed by scroll display or the like.

  According to the wood management system of the present embodiment, the wireless IC tag 6 attached to the wood that is unloaded from the supply place and processed thereafter stores information about the certificate issued at each time point, and manages this information. By providing it to the server 1, it is possible to realize the traceability management of wood corresponding to FIT.

(Other embodiments)
In the embodiment described above, the management server 1 outputs the wood type and FIT price so that each information terminal can view the type and FIT price. For example, the management server 1 may output only the type of wood without outputting the FIT price. Even in this case, if the browsing side grasps the correspondence between the type of wood and the FIT price, it is possible to derive the FIT price from the correspondence.

  In the above-described embodiment, the management server 1 is configured by a single computer. However, various device configurations are assumed such as the management server 1 being realized by a distributed system including a plurality of computers. obtain.
