Description

[Technical Field]

[0001] The present invention relates to a cattle auction system that anyone can freely participate in using an electronic trading screen that integrates carcass auctions held at central meat wholesale markets in each region, and a bidding and winning bid processing method for the cattle auction system. [Background technology]

[0002] In recent years, an environment has been developed in which anyone can bid on a used car registered for auction using an auction system that allows electronic trading of used cars. On the other hand, the current situation in the carcass industry is that an auction system that allows electronic trading has not yet been established.

[0003] Specifically, beef and pork sold domestically are first raised on ranches and pig farms, and after a designated period of time, the cattle and pigs are butchered at a butchering facility called a "butchering yard," then auctioned off in whole, half, or cuts at meat markets, and are then sold through middlemen to butcher shops and supermarkets. This is the general flow of carcass trading. Meanwhile, an online auction management system that computerizes the trading of calves has already been made public (Patent Document 1 below). Here, Patent Document 1 discloses an auction transaction for live cattle (excluding calves), live mother cows, and live castrated cattle.

[0004] This document explains that livestock trading in Japan is based on livestock markets being opened and operated by entities registered by prefectural governors, with sales conducted through auctions or bidding, and that markets are opened in specific areas, with approximately 100 markets held regularly across the country.

[0005] Furthermore, in the carcass trade in Japan, emphasis is placed on the pedigree of each individual cattle, and it is common to assess the qualities and health condition of each individual before trading, and this tendency is particularly strong in the Japanese Black cattle.

[0006] In Japan, the distribution of beef cattle is divided into different stages of development: breeding farms, which impregnate mother cows and raise the resulting calves until they are about four months old; rearing farms, which further raise the newborn calves until they are about eight months old; fattening farms, which fatten the cattle from eight months old for about 30 months; slaughterhouses, butchers, and retailers; and the livestock markets mentioned above are mainly used for transactions between breeding farms and fattening farms. With the recent development of communication technology, various goods and services can now be purchased through virtual stores on the Internet, and transactions are no longer limited to those between traders and consumers; they can also be conducted directly between consumers through systems provided by traders. This type of transaction eliminates the need to go to an actual store or transaction location, thereby reducing the cost of transporting goods to stores or markets. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 2019-192239 Summary of the Invention [Problem to be solved by the invention]

[0008] However, the environment for electronic trading of carcasses raised on farms and pig farms and slaughtered at slaughterhouses, while managing them on an electronic trading system, was not yet in place.

[0009] As a result, carcass traders had to arrange for a refrigerated transport vehicle and travel long distances from their home bases to each carcass trading market across the country each time a carcass market was held, taking the time to identify the carcasses that were up for auction and place bids. As a result, if a trader goes to an auction and finds that only unprofitable carcasses are listed, he or she must return to the base in an empty refrigerated transport vehicle, and the labor costs and transportation costs (including fuel costs) must all be treated as wasted expenses. If there are no carcasses to bid at multiple auction venues, the economic burden on the trader becomes even heavier, which creates problems. On the other hand, carcasses are raw food, and even discerning traders may find it difficult to decide whether to purchase them if they cannot visually confirm the leanness of the meat and the state of marbling (the amount of fat in the carcasses). Therefore, it is difficult for carcass traders to make purchases without traveling to markets across the country and visually checking the quality of the meat at each market. In addition, currently, in the electronic trading of beef, carcasses aged 9 months or older (including early-season cattle), live animals that have been fattened for 30 months after birth, carcasses (blocks of meat with the bones removed), and meat extracted from live animals at the slaughterhouse (various internal components, so-called hormones) are not publicly traded online, especially not through auctions. In addition, the current auction process for carcasses relies on analog processes, such as circulating a document called an auction schedule to meat wholesalers to confirm the source of acquisition, sender, place of origin, pedigree, age in months, carcass weight, specifications, unit price, etc.

[0010] Furthermore, in the current meat auction market, the deboning of carcasses that have been won is usually monopolized by the organization that manages the meat processing center that manages the market, and there is no further price competition, resulting in an oligopoly. As a result, it has been pointed out that traders who have won bids on carcasses are unable to request deboning at a fair price based on free competition, which is an issue with the market system.

[0011] The present invention has been made to solve the above-mentioned problems, and its object is to provide a cattle auction system and a method for processing bidding and winning bids at cattle auctions, which establishes a cattle auction system that allows communication between each auction hall across the country where cattle are traded and auctioneers, and enables a bidder to reliably purchase the desired cattle and carcasses from the cattle through remote electronic transactions, while using a display image to distinguish the actual meat quality, which is difficult to judge from the market grade alone.

[0012] Furthermore, the present invention provides a cattle auction system and a method for processing bids and successful bids at cattle auctions that enable traders participating in a meat auction to bid at a mutually agreeable price, including the cost of deboning processing after the carcass has been sold. [Means for solving the problem]

[0013] The cattle auction system of the present invention that achieves the above object comprises the following configuration.

[0014] A meat auction system in which a server device for electronically trading cattle including live cattle or meat slaughtered or processed at a slaughterhouse and a plurality of data processing devices operated by a plurality of bidders to participate in an auction of live cattle and carcasses slaughtered from slaughtered cattle provided by the server device can communicate with each other, wherein the server device has a receiving means for receiving a request for bidder registration from each data processing device, a determining means for determining whether or not to accept the received request for bidder registration based on registration criteria, an issuing means for issuing identification information to identify registered bidders, a registering means for registering evaluation information for evaluating the cattle, and an acquiring means for registering evaluation information for evaluating the cattle. Identification a reply means for replying a list of transaction information including the information, and ... , placea display control means for updating the display mode of the transaction information for the cattle displayed on a predetermined auction screen, a determination means for determining the bidder who finally bids for the cattle at the desired withdrawal amount as the successful bidder on the predetermined auction screen if the display mode does not change after a predetermined time has elapsed, and a notification means for notifying the confirmed successful bidder of the successful bid, and each data processing device has a receiving means for receiving identification information issued from the server device, a login means for logging in to the predetermined auction screen provided by the server device using the identification information, and a login means for notifying the bidder of the withdrawal amount for the cattle being auctioned displayed on the predetermined auction screen. , each time you process a bid request. a bidding means for uploading a bidding result, a receiving means for receiving a successful bid notification from the server device, and a bidding means for selecting the successful bid from the list of transaction information obtained from the server device. Identification and a display control means for extracting the information and displaying an image of the live cattle or the meat to be butchered from the live cattle on a display means. [Effects of the Invention]

[0015] According to the present invention, a cattle auction system is constructed that allows communication between each auction hall across the country where cattle are traded and auctioneers, and enables bidders to reliably purchase the desired cattle and carcasses from the cattle they wish to purchase from the listed cattle through remote electronic transactions while assessing the actual meat quality, which is difficult to judge based on the grade assessed in the market alone, using a displayed image.

[0017] Next, the best mode for carrying out the present invention will be described with reference to the drawings.

[0018] <Explanation of meat auction system configuration> [First embodiment] Next, a best mode for carrying out the present invention will be described with reference to the drawings. In this example, a meat auction system is shown, in which a server device 1 for electronically trading carcasses processed at a slaughterhouse can communicate with a plurality of data processing devices 2-1, 2-2, and 2-3 operated by a plurality of bidders to participate in a carcass auction hosted by the server device 1. In this embodiment, the term "bidding" refers to an auction. The grade of carcasses is determined by graders stationed at each market. For example, the grade of the cut surface is determined by examining the longissimus thoracis (loin center), semispinalis dorsalis, and spinalis capitis muscles on the cross section to determine the marbling. Additionally, the thickness of the rib, subcutaneous fat, and intermuscular fat are also examined to determine the "meat quality" and "yield." The yield grade, calculated based on the yield standard value (a predetermined calculation formula), is divided into three grades, A, B, and C, in descending order of quality. Similarly, the meat quality grade is divided into 5, 4, 3, 2, and 1, and a combination of these is displayed as "A5," for example. It is also known that meat quality differs between males and females.

[0019] The data processing device 2-1 functions as a terminal used by buyers and sellers who can take part in the meat auction (retailers, food processing businesses, cooperative purchasing organizations, etc.).

[0020] The data processing device 2-2 also functions as a terminal used by buyers (retailers, processors, food service operators, etc.) who can participate in the meat auction.

[0021] Furthermore, the data processing device 2-3 functions as a terminal used by intermediate wholesalers (processors) who can participate in the meat auction.

[0022] Furthermore, the system is configured so that buyers and sellers who have won a carcass at a meat auction by operating the data processing device 2-1 can request intermediate wholesalers to de-boning the carcass at a processing fee set by the buyer and seller, thereby securing an additional source of income for the intermediate wholesalers.

[0023] Therefore, by configuring the screen showing the successful bid for carcass to allow the user to select the carcass deboning processing fee and processor request, a new carcass processing business can be developed. In other words, meat auction participants can bid at a price that is mutually agreeable to them, including the cost of deboning the carcass after it is sold.

[0024] Figure 1 is a block diagram illustrating the configuration of a meat auction system according to this embodiment. While this example illustrates a system in which a live cattle slaughterhouse and a meat market are adjacent to each other, the present invention can also be applied to a system in which the slaughterhouse and meat market are located independently and separately. Furthermore, the cattle auction shown in this example can also be applied to an auction of live cattle, as will be described later. Furthermore, the meat auction system can be expanded by incorporating additional functions such as product listing management, auction bid management, auction results management, customer management, communication functions, a function for previewing carcasses the day before (via video streaming), and billing and payment management (for successful bidders). Below we will provide a detailed description of the SETTOKO system (KOREIRU), which is built as a cloud-based package service.

[0025] In FIG. 1, the server device 1 includes a controller unit 33, which controls the display mode of the bidding screen displayed on the display device 31 via a display control means 32 in real time.

[0026] When the communication unit 40 is connected to the network 3, it is communicatively connected to the communication unit 25 of the data processing device 2-1 installed at the market. The data processing device 2-1 registers surface images of the processed entire carcass 11-13 captured by the camera 22 and cut images of the meat cut surfaces in the registration unit 23, with a predetermined identification number assigned. The image of the entire carcass is evaluated by the connoisseur as an important image guide for evaluating the entire cattle. Specifically, the image includes the thickness of the hind leg bones (thinner is better), the firmness of the hind thighs (firmer is better), the size of kidney fat (an indicator of nutritional status), the thickness of the back fat (thinner is generally better), the inner fat (more fat is better), the thickness of the ribs (thinner is better), and the thickness of the front leg bones (thinner is better). Including such an entire image and images of each part in the listed information provides the auctioneer with effective information for determining whether or not the meat is worth bidding on.

[0027] In this embodiment, on the auction screen described later, a pre-registered cross-section image chart (for example, five levels) and the meat cross-section image taken at the slaughterhouse are displayed side by side so that the color and fillet condition can be visually compared.

[0028] This allows, for example, a professional auctioneer who is certified as a cut meat production master to have the discerning eye of a professional, and also allows amateur auctioneers to easily and intuitively evaluate the quality of the meat being auctioned by referring to the color and marbling of the contrasting images. In other words, with just the grade, there are cases where the elements that an auctioneer wants to win cannot be determined unambiguously based on elements other than the grade. In other words, for an auctioneer, evaluations such as the ratio of fat to lean meat or the marbling are not always unambiguously determined.

[0029] The input unit 24 assigns detailed grades, pedigrees, producers, slaughter date and time, part names (in this embodiment, 13 types of parts are recognized), sex, and other information to the processed carcasses based on the carcass identification information. Each slaughterhouse is assigned a unique identification code, and each is managed by a single identification code within the country. The camera 22 is connected to the data processing device 2-1 via a predetermined interface cable and transfers captured image data (cut images (e.g., high-definition 4K image data)) to the registration unit 23. The color and luster of the meat are graded on a scale of 1 to 7, and the color and luster of fat and quality are also graded on a scale of 1 to 7. By registering these reference images in advance, the grade evaluation of the carcasses to be traded can be visualized. The auctioneer can compare the reference cut image with the cross-sectional image of the meat, allowing for meaningful bidding that reflects the auctioneer's discerning eye.

[0030] In the meat auction system of this embodiment, a receiving means 34, a determining means 35, an issuing means 36, a registering means 37, a confirming means 38, and a notifying means 39, which function as programs, are stored in an external storage means such as a hard disk or SSD (not shown), and the controller unit 33 loads the programs into a RAM (not shown) or the like and executes them to realize various data processing operations, which will be described later.

[0031] The network 4 connects the communication units 57 of the data processing devices (so-called personal computers (PCs)) 2-1, 2-2, 2-3 operated by bidders who log in to the meat auction system and participate in the auction to the communication unit 40 of the server device 1, and realizes a unique carcass auction process (auction process) via an auction screen (shown in FIG. 6, which will be described later) displayed on the display unit 58. Here, the auction screen is generated by activating an auction application installed in the data processing devices 2-1, 2-2, 2-3, and the auction screen is displayed on the display unit 58. The controller unit 51 may display the bidding screen on the display unit 58 by acquiring screen data from the server device 1. This reduces the burden of updating and managing the screen data on the data processing device side. The data processing devices 2-1, 2-2, and 2-3 are provided with substantially the same hardware (CPU, ROM, RAM) and the following various means as software (programs). The controller unit 51 loads onto RAM a receiving means 53, a login means 54, a bidding means 55, a receiving means 56, and software (auction application) that performs the specified functions, thereby realizing various data processing functions described below.

[0032] The server device 1 of the meat auction system configured in this manner comprises: a receiving means 34 for receiving a request for bidder registration from any of the data processing devices 2-1 to 2-3; a determining means 35 for determining whether or not to accept the received request for bidder registration based on registration criteria; an issuing means 36 for issuing identification information that identifies the registered bidder; a registering means 37 for registering evaluation information for evaluating the carcass; an auction display control means 32 for generating an auction screen to be displayed on a predetermined display device 31 referenced by the auctioneer based on the registered evaluation information, accepting bid requests from one or more registered bidders, and changing the display mode of the carcass transaction information displayed on the predetermined auction screen; a determining means 38 for determining, on the predetermined auction screen, the bidder who finally bids the carcass at the desired withdrawal price as the successful bidder if the display mode does not change after a predetermined time has passed; and a notifying means 39 for notifying the confirmed successful bidder of a successful bid.

[0033] In this embodiment, the above-mentioned means 34 to 39, excluding the auction display control means 32, are configured as one auction application 41, but a configuration may also be adopted in which means for executing functional processing useful for the auction system are further added in addition to the above-mentioned means 34 to 39. Note that in the following explanation, an example will be described in which the functional processing of the above-mentioned means 34 to 39 is integrated and processed by one auction application 41.

[0034] In addition, the data processing devices 2-1 to 2-3 of the meat auction system include a receiving means 53 that receives identification information issued from the server device 1, a login means 54 that uses the identification information to log in to a predetermined auction screen (see Figure 6) provided by the server device 1, a bidding means 55 that uploads in real time the amount withdrawn for the carcass being auctioned that is displayed on the predetermined auction screen, and a receiving means 56 that receives a successful bid notification from the server device 1.

[0035] Here, a case where the above-mentioned components 53 to 56 are configured as one bidding application 59 will be described, but a configuration in which means for executing functional processing useful for the bidding system are further added in addition to the above-mentioned components 53 to 56. Note that the following description will be given as an example in which the functional processing of the components 53 to 56 is integrated and processed by one bidding application 59.

[0036] Here, the server device 1 employs a system that rigorously examines requests for qualification from those who meet the conditions for participating as an bidder (i.e., those who have the ability to pay (a specified amount of money in a bank) and have not been registered as having a trading suspension for the past few years) and grants the bidder qualification to them, thereby managing transactions so that they are not disrupted.

[0037] In response to an auctioneer registration request, the receiving means 53 of each auctioneer of the data processing devices 2-1 to 2-3 receives, as an examination result from the server device 1, identification information required for participating in the auction, and registers this information in the auction application 59. As a result, the auction application 59 and the auction application 41 of the server device 1 communicate with each other, while the auction application 41 processes the login and logout of each auctioneer via the login means 54 and the bid request via the bidding means 55. As a result, the auctioneer can freely participate in the auction by activating the auction application of the data processing devices 2-1 to 2-3 and uploading the amount withdrawn for the cattle being auctioned in real time via the auction screen displayed on the display unit 58 (similar to the auction screen displayed on the display device 31).

[0038] Figure 2 is a diagram showing an example of carcass identification information managed by the data processing device shown in Figure 1. In this example, an excerpt of carcass information (transaction information including identification information for each carcass) published at, for example, the Kyoto Meat Market is shown.

[0039] As shown in FIG. 2, transaction information including the identification information for each carcass is acquired from the server device 1 and temporarily stored in a list folder allocated to a storage device managed by the controller unit 51, such as an SSD or HDD. The transaction information includes the slaughter date, auction order, listing number, breed, sex, shipper (producer), farm HACCP, place of origin, pedigree background (sire, dam'sire, grandfather's sire, birthplace, date of birth, age in months, and live weight). In this embodiment, the same information can be viewed on a display device connected to the auctioneer's data processing device by operating a UI screen, which will be described later. The identification information for each carcass is stored in a cross-section image folder in a storage device managed by the controller unit 33, where cross-section images of the carcass captured by the server device 1 using a camera 22 connected to the auction site data processing device 2-2 are stored as compressed color images, corresponding to the transaction information number. In addition, the storage device also pre-registers standard cross-sectional images for comparing the cross-sectional images of the listed carcasses to be graded (12 grades), a standard chart for meat color and luster grades, and a chart showing the grades of fat, color and quality.The cross-section of the carcass is based on a cross-sectional image of the carcass cut (left half) between the 6th and 7th ribs.

[0040] As a result, the data processing devices 2-1 to 2-3 operated by the auctioneer can recognize in advance before the start of the auction information on the carcasses registered on the bidding day, especially whether any carcasses of noteworthy individuals are listed, and therefore information that could previously only be found at the auction site can be viewed online, thereby reducing travel costs including fuel costs. Furthermore, if a carcass of a noteworthy individual is listed, a cross-sectional image of the cut carcass can be displayed as a color image on the display unit 58, allowing the auctioneer to carefully examine it, eliminating the need to bid on useless carcasses. The evaluation of the cross-sectional image displayed on the display unit 58 uses the lowest evaluation of the multiple evaluation information, so even if the marbling is 5, if the lean meat grade is 3, the overall evaluation will be 3 (details will be described later). Therefore, by displaying in detail the cross-sectional image of the appraisal information obtained in advance on the display unit 58, the auctioneer can bid on a carcass that has a low lean meat grade but a high degree of marbling, or a carcass that has a low marbling grade but a high degree of lean meat. In other words, the auctioneer can select in advance the carcass that he or she wishes to bid on, depending on his or her preferences for lean meat and marbling, specifically by evaluating the cut images with his or her discerning eye.

[0041] FIG. 3 is a diagram showing an example of detailed information on the class, which is part of the identification information managed by the server device 1 shown in FIG.

[0042] In this embodiment, beef grades are indicated in the form of "alphabet + number" such as A5, A4, A3, etc. The grades are determined by the Japan Meat Grading Association based on the beef carcass trading standards approved by the Ministry of Agriculture, Forestry and Fisheries.

[0043] The alphabetical part here is called the yield grade, which is a rank that evaluates "how much marketable beef can be obtained from that cow." It is a productivity rating, so to speak. There are three ranks, from A to C, with A being the highest rank.

[0044] Meanwhile, the numerical part is called the meat quality grade, which is a rank that comprehensively evaluates four factors: "beef color and luster," "beef firmness and texture," "fat color and luster and quality," and "fat marbling (amount of fat)." There are five levels, from 1 to 5, with 5 being the highest rank. In other words, A5 means "a lot of beef that can be sold is harvested, the fat color and luster and quality, the beef color and luster, firmness, and texture are good, and there is a lot of fine fat."

[0045] Next, we will explain yield grades.

[0046] Yield grades are an evaluation of "how much marketable beef can be obtained from a cow." More specifically, they show how much marketable cut meat can be obtained from the carcass (which is the meat obtained by removing the head, skin, feet, and internal organs) by looking at the area of ​​the loin and rib between the 6th and 7th ribs.

[0047] The Japan Meat Grading Association defines the following 14 cuts as "cut meat." In detail, they are neck, shoulder, shoulder loin, shoulder belly, fillet, rib eye, sirloin, thigh, belly, inner thigh, thigh, rump, outer thigh, and shank.

[0048] In this embodiment, the meat quality grade, as the name suggests, means a rank that evaluates the "quality of beef." Specifically, the following items will be evaluated: Marbling, color and quality of fat, firmness and texture of beef, and color and luster of beef are all ranked on a scale of 1 to 5, with 5 being the highest rank for all. It is important to note that the lowest rank among these four items will be the final meat quality grade for the beef.

[0049] For example, even if the color and quality of the fat, and the color, firmness, and texture of the beef are all rated "5," if the fat marbling is rated "3," the beef's meat quality grade will be "3."

[0050] As a result, meat from breeds such as Japanese Brown and Japanese Shorthorn, which are naturally low in fat, tends to have a lower meat quality grade. Here, marbling refers to the way fat (marbling, marbling) is distributed.

[0051] 4 is a diagram showing an example of a confirmation screen for a cut image that can be displayed by the data processing devices 2-1 to 2-3 shown in FIG. 1, and in this example, a cut image of a pre-registered standard grade is displayed in comparison with a cut image captured by the camera 22. An example of detailed grade information among the identification information to be managed is shown. This example shows a case where the cut image is displayed as a thumbnail, but it is also possible to display an enlarged cut image on the display unit 58 as described below.

[0052] This allows even non-experienced auction participants to intuitively evaluate the degree of leanness in the cross-sectional image and the specifics of the cuts. By clicking on the thumbnail image, it is also possible to enlarge it on a high-definition (4K / 8K) screen. Furthermore, if the system is configured to display a color still image or video of the entire living organism before it is cut, the auctioneer can make a comprehensive judgment based on various information that cannot be determined from numerical data alone, and narrow down the carcasses to be bid on. Carcasses that are listed and traded at meat markets around the country are graded by graders (staff of the Japan Meat Grading Association) who are stationed at each market. Graders grade in accordance with the Act on Price Stabilization, etc. of Livestock Products (Livestock Safety Act), and the grade is stamped directly onto the surface of the carcass. The grading of the cut surface is determined by examining the longissimus thoracis (loin core), semispinalis dorsalis, and spinalis capitis muscles on the cross section to determine the marbling level, and in addition, the thickness of the rib, subcutaneous fat, and intermuscular fat is also examined to determine the "meat quality" and "yield." Yield grades are divided into three levels, A, B, and C, in descending order of quality, and meat quality grades are similarly divided into 5, 4, 3, 2, and 1, and the two are combined to be displayed as "A5," etc. Furthermore, in this embodiment, cross-sectional images of each part of the carcass being auctioned are displayed on the display unit 58, thereby enabling the auctioneer to make an effective and appropriate transaction. Here, the parts include head A, semispinalis dorsalis B, rhomboid C, longissimus thoracis (loin) D, semispinalis capitis E, rib F, subcutaneous fat G, and latissimus dorsi H. In this embodiment, the cross-sectional images that can be displayed are registered with a resolution that allows detailed confirmation of the above-mentioned head A, semispinalis dorsalis B, rhomboids C, longissimus thoracis (loin) D, semispinalis capitis E, rib F, subcutaneous fat G, and latissimus dorsi H. In this embodiment, since the camera 22 has a still image function, the cross-sectional images are captured at a resolution set for the camera 22 (for example, 4K level).

[0053] FIG. 5 is a diagram showing an example of an auction winning bid information screen that can be confirmed on the server device 1 shown in FIG. 1, in which the winning bid price and the ID of the winning bidder are displayed opposite each other for each listing number. It is also possible to tally the winning bid amount per auction day for each ID and issue a receipt to the successful bidder.

[0054] Figure 6 is a diagram showing an example of an auction screen provided to the data processing devices 2-1 and 2-3 by the server device 1 shown in Figure 1. The START price at the start of the auction is calculated from the standard deviation set for that grade, but can be set higher or lower than that price at the discretion of the auction company.

[0055] As shown in FIG. 6 , this embodiment shows the auction screen displaying the auction date and time 71, the starting price 72, the listing number 73, the grade 74, the comparison image display 75, the bid increase price display 76, and the price difference display 77. However, the display format is not limited to this example and may include additional visual elements, such as video images of individual animals before the auction. Furthermore, when the auctioneer operates an input device to select a cross-sectional image displayed on the auction screen 58, an evaluation application may be launched to compare the cross-sectional image displayed on the display 58 in detail with a reference cross-sectional image registered in a database. The auctioneer may then compare the cross-sectional image with the cross-sectional image of a previously successful auction and perform an image diagnosis to evaluate the image. This allows assistants other than the auctioneer to conduct a bid that rivals the auctioneer's discerning eye. The grade 74 also includes the fat marbling grade (BMS (Beef Marbling Standard)), the meat color / luster grade (BCS (Beef Color Standard)), the fat color / luster and quality grade (BFS (Beef Fat Standard)), etc., and the auctioneer may be configured to be able to visually confirm this grade information by indicating the grade 74 on the display unit 58.

[0056] In the display modes of the mid-bidding UP price display unit 76 and the determined differential price display unit 77, under the control of the display control means 32, the mid-bidding UP price display unit 76 displays the entirety on a green background with price fluctuations in flashing red numbers, and the determined differential price display unit 77 displays the entirety on a red background with withdrawal prices in black numbers. Changes in the display modes of the mid-bidding UP price display unit 76 and the determined differential price display unit 77 controlled by the display control means 32 are reflected on the display unit 58 via the bidding app of the data processing devices 2-1 to 2-3.

[0057] However, the configuration of the UI screen is just one example, and as long as it is possible to intuitively determine whether the price currently displayed on the UI screen is the bid increase price or the withdrawal price, the form is not limited to this example.

[0058] In this example, the bidding started at 2,500 yen per kg, and about three minutes later, the item was sold at 2,850 yen per kg. Note that while the bidding is open to any bidder, it may also be increased by a predetermined unit price.

[0059] In addition to the above price settings, the auction system may be configured to allow a one-shot price (instant bid price) to be set, so that for a carcass that an auctioneer is interested in and wants to win, the carcass can be purchased without wasting time on the auction, as long as the set price is in line with the seller's wishes.

[0060] For example, if the starting price of the auction is ¥2,500 / kg, the bidder can operate the terminal to input an immediate winning bid of ¥3,500 / kg, and the seller can press the agreement button to complete the auction.

[0061] In this case, the winning bid price can be selectively set to be displayed publicly or privately, and if the bidder selects private display of the winning bid price, the winning bid price (the price entered by the bidder) can be controlled so that only the seller can see it.

[0062] On the other hand, if the seller has selected to make the immediate successful bid price publicly available, the system may be controlled so that all participating bidders can see the immediate successful bid price (the price entered by the bidder) on the auction screen.

[0063] [Auction processing method for the auction system] 7 is a flowchart illustrating the procedure of the auction processing method for the meat auction system according to this embodiment. Note that S200 to S214 represent individual steps, which are implemented by the controller unit 33 of the server device 1 loading stored software (including the auction application 41) into a RAM (not shown) or the like and executing the software. Also, S300 to S305 are implemented by the controller unit 51 of the data processing devices 2-1 to 2-3 loading stored software (the auction application 59, described below) into a RAM (not shown) and executing the software.

[0064] Next, the server device 1 receives transaction information for the carcasses to be listed from the data processing device 2-1 and registers it in the storage device (steps S200, S201). By, for example, two days before the auction, the registration means 37 sequentially receives and registers transaction information, including identification information for each carcass related to the cattle to be listed by the producer, in a transaction database (not shown). The transaction information includes the butchering date, auction order, listing number, etc., as shown in FIG. 3.

[0065] Next, prior to the start of the auction, the server device 1 distributes (transmits) transaction information for the cattle to be listed (see FIG. 3) to the auctioneer's data processing device 2-1 (S202). The auctioneer's data processing device 2-1 receives the transaction information for the carcass sent from the server device 1 via the network 4 (S300).

[0066] Next, the controller unit 51 of the auctioneer's data processing device 2-1 stores the transaction information for the carcass received from the server device 1 in the storage device of the auctioneer's data processing device 2-1. The auctioneer searches for and views transaction information for the cattle that will be listed on the day of the auction (S301). This allows the auctioneer to remotely check the transaction information for the listed carcass on the auction screen displayed on the display unit 58 of the data processing device 2-1 installed in the auctioneer's home (S30D).

[0067] That is, before the start of the auction, the auctioneer can preview the carcasses (carcasses (corresponding to each part put up for auction)) to be put up for auction on the display unit 58 of the data processing device 2-1. Note that before the start of the auction, the bidding switch displayed on the display unit 58 by the auction application for bidding processing installed in the data processing device 2-1 is disabled, and the auctioneer operating the data processing device 2-1 cannot place a bid on the put up carcasses.

[0068] The successful bidder (bidding participant) inputs his / her desired conditions on a search screen (not shown) displayed on the display unit 58 of the data processing device 2-1. The search conditions are configured to allow the input of, for example, grade, name of the cut part, cut surface image, etc. These search conditions can be used alone or in combination. Next, by executing a search, a list of trading information for cattle that matches or is similar to the search criteria is extracted and displayed on the screen of the display unit 58 of the data processing device 2-1 (generated by extracting from the trading information displayed in Figure 3).

[0069] Next, by selecting a specific listing number on the list display screen, detailed characteristic information for the listed cattle can be displayed (Fig. 4). The thumbnail-format cross-sectional image screen shown in Fig. 5 displays a detailed color screen that allows for comparison of the cross-sectional image of the listed carcass with cross-sectional images for each grade registered as a standard. If the listing number of the desired cattle is known in advance, the bidder can specify the listing number to cause the display unit 58 of the data processing device 2-1 to display the carcass identification information shown in Fig. 4, which is associated with the transaction information for the carcass desired by the bidder.

[0070] As a result, prior to the start of the auction, auctioneers can preview cross-sectional images of the cattle to be auctioned by displaying the identification information screen of Figure 3 and the thumbnail screen of Figure 4 on the display unit 58, and can decide in advance which of the listed carcasses they will participate in the auction for. This eliminates the need for labor costs, fuel costs, etc., required to travel from a long distance to the auction venue to participate in a conventional auction, and allows for significant cost savings.

[0071] Furthermore, as described above, the bidding system of this embodiment not only allows for real-time bidding in which bids are placed at prices that change sequentially, but also allows for a system in which order-receiving users can input bid prices in advance before the bidding begins.

[0072] The auctioneer operating the data processing device 2-1 can participate in the auction and win a bid for the desired meat while referring to the auction screen, an example of which is shown in Figure 6. The user who wins the bid operates the input unit 52 to input a price (bid price) that they consider to be reasonable on the auction screen displayed on the display unit 58 by an auction application installed on the data processing device 2-1, and transmits this bid price to the server device 1 and registers it in the auction application of the server device 1. This allows the auctioneer of the data processing device 2-1 to win the listed beef carcass if there is no other bidder up to that bid price after the auction begins.

[0073] In a normal bidding process, when the bidding start time arrives, the server device 1 sends an auction start signal to the participating data processing devices 2-1 to 2-3 to notify them of the start of the bidding (S203). As a result, the bidding applications of the data processing devices 2-1 to 2-3 control the acceptance status of their bid switches to be valid.

[0074] FIG. 6 shows an auction screen on which bids are made for listed cattle that are the subject of auction. The auction screen in this embodiment displays the current price (bidding price) of the listed cattle, transaction information for the listed cattle, and the like. In FIG. 6, reference numeral 100 denotes a bid button, which is pressed by the bidder of data processing devices 2-1 to 2-3 to confirm a bid at the displayed price. Reference numeral 101 denotes an auction timer, which counts down, for example, three minutes in seconds, and the price displayed at "00:00" is confirmed as the bid price. The auction timer 101 is configured to allow the bidder to input a desired bid price at a desired timing while carefully monitoring the auction timer 101.

[0075] Next, the current price (bidding price) of the cattle to be auctioned is set to the initial value, the starting price (for example, 2,500 yen) in server device 1 (S204).The auction application of server device 1 then transmits the set starting price to data processing devices 2-1 to 2-3 (S205).

[0076] As a result, the auction application of the data processing devices 2-1 to 2-3 displays the current price of the carcass being auctioned on the display unit 58 via the UI screen shown in Fig. 6. In the meat auction system of this embodiment, the current price is automatically increased and updated every predetermined time (for example, every 5 seconds) until a bid is made by any bidder or until the current price reaches the upper limit price.

[0077] Here, the auction application 59 checks the current price and other information (cut surface image of the meat) displayed on the display unit 58 and determines whether the auctioneer operating the data processing device 2-1 has pressed the bidding switch 100 shown in Fig. 6 (S302). As a result, the auction application 59 detects that the auctioneer has pressed the bidding switch 100, determines that the auctioneer will bid on the listed carcass (S303), and notifies the auction application 41 of the server device 1 of this fact (as a bidding signal) via the network 4.

[0078] On the other hand, if the bidding application 59 detects in S302 that the bid switch 100 has not been pressed by the bidder, the process proceeds to S304.

[0079] As a result, the bidder notifies the bidding application 41 of the server device 1 of his / her intention to bid by responding to the bid or ignoring the bid, based on the pressing status of the bid button 100 and the bid price during the bidding, via the bidding application 59 installed in the data processing device 2-1.

[0080] In response to this, the bidding application 41 of the server device 1 determines whether or not there is a bidding signal from the bidding application 59 of the data processing device 2-1, and determines whether or not there is an intention to bid from any of the bid inputs (S206). As a result, if the bidding application 41 of the server device 1 determines that it has received a bidding instruction from any bidder, it performs a process to determine a successful bidder (S207).

[0081] Specifically, on the real-time left bidding screen shown in Figure 6, if the bid price does not change for a predetermined time, for example, 3 minutes, the bidding application 41 of the server device 1 determines the currently displayed bid price as the successful bid price and determines the bidder who entered that bid price as the successful bidder.

[0082] In the main carcass auction system, if there are bids from multiple bidders, the order-receiving user who placed the bid first will be determined as the successful bidder. In other words, if there are multiple users who placed bids at the same price, the bidder of the data processing device that pressed the bidding switch 100 first among the data processing devices 2-1 to 2-3 will be determined as the successful bidder.

[0083] Therefore, the server device 1 does not determine the successful bidder from among multiple bidding signals that reach the server device 1, but simply determines the data processing device 2-1 that transmitted the bidding signal that reached the server device 1 first as the successful bidder. As another determination method, an automatic lottery system that assigns numbers generated by a random number machine that generates random variables may be used, and the bidder with the smallest or largest number may be determined as the final bidder.

[0084] When the auction application 41 determines a successful bidder, the server device 1 notifies one of the data processing devices 2-1 to 2-3 of the successful bidder that the bidder has won the bid for the listed carcass (S208).

[0085] As a result, a message indicating the listing number and successful bid price of the carcass to be auctioned is displayed on the display unit 58 of the data processing device of the successful bidder (any one of data processing devices 2-1 to 2-3). In addition, the auction application 41 of the server device 1 notifies the bidders other than the successful bidder that another bidder has won the bid for the listed carcass. In addition, the controller unit 33 of the server device 1 stores in a storage device information related to the successful bid for the carcass, including the successful bid price and handling data such as land transportation costs for the successful bid, and creates a successful bid carcass database for managing the successful bid for the carcass.

[0086] On the other hand, if no bidders submit a bid, the controller unit 33 performs a lower bid via the bidding application after a predetermined time has elapsed (S209). Specifically, the current price is reduced by a preset amount (for example, 250 yen) and a new current price (for example, 2,250 yen) is set.

[0087] Next, the controller unit 33 determines whether the new current price is below the minimum price via the bidding application 59 (S210). As a result, if it is determined that the new current price is not below the minimum price, the process returns to S205, and the controller unit 33 transmits the new current price to the data processing devices 2-1 to 2-3 of the bidders participating in the auction.

[0088] On the other hand, if the controller unit 33 determines via the auction application 41 that the new current price is several tens of percent lower than the lower limit price, the listed meat is deemed unsold (S211) and the process proceeds to step S212.

[0089] In S212, if the controller unit 33 determines via the auction app that the listed meat has been sold or that the listed meat has been sold, it determines whether there is any meat to be auctioned next (S212). As a result, if the controller unit 33 determines via the auction application 41 that there are still listed carcasses remaining, the process returns to S204 and the above-described carcass auction is repeated.

[0090] On the other hand, if the controller unit 33 determines via the auction application 41 that the auction has ended for all listed carcasses, the controller unit 33 sends a message 41A to the data processing devices 2-1 to 2-3 via the auction application to indicate that the auction has ended (S213).

[0091] In response to this, the data processing device 2-1 determines whether the installed auction application 59 has received a termination notification from the server device 1, and if it determines that the termination notification has not been received, it returns to S302 and repeats the carcass auction process in the same manner, and if it determines that the termination notification has been received, it determines that the carcass auction should be terminated (S304).

[0092] Meanwhile, after the bidding ends, the auction application 41 of the server device 1 notifies the successful bidder of one of the data processing devices 2-1 to 2-3 via the network 4 of the successful bidder's confirmation of the successful bid (S214). Thereafter, the original bidder hands over the successful bid meat to a delivery person who will transport the refrigerated carcass (S215), and this process ends.

[0093] Meanwhile, the data processing devices 2-1 to 2-3 transfer the winning bid fee, delivery fee, and handling fee for the successful bid carcass to the designated account, and execute a settlement process to update the balance by deducting the transferred amount from the deposit balance (305), and then terminate this process.

[0094] As a result, auctioneers scattered across the country can participate in the auction from their local locations, i.e., without traveling to the auction venue, simply through the auction screen of the auction application displayed on the display unit 58 of the data processing device, and can easily and effortlessly complete various procedures from bidding on desired carcasses one after another to delivery while referring to detailed transaction information for the listed carcasses to be auctioned before the auction begins. In this way, the system of the first embodiment is configured so that a discerning bidder can visually check the meat quality of the carcasses being traded and distinguish the graded meat quality condition, and by changing the display mode of the transaction information during the auction, an environment can be created in which participating bidders can remotely bid on the carcasses they want while visually checking useful transaction information.

[0095] Second Embodiment In the above first embodiment, an example of auctioning carcasses of Wagyu beef has been described, but the present system can also be applied to auctioning carcasses of pork. This allows impartial auctioneers who are able to participate in the auction of brand pigs to freely bid on carcasses listed on the national market even if they are away from the auction venue.

[0096] Third Embodiment In the above embodiment, an example was described in which the auction app simply displays a cut image of a reference cut surface of a half body of Wagyu beef on the auction screen displayed on the display device 31 so that the cut image can be compared, but it may also be configured to display a reference meat quality grade, a color image of the meat that serves as the reference for that grade, and a color image of the meat being bid so that the color image can be compared. In this case, the auction app may be configured to display a predetermined auction screen in which the standard meat quality grade, a color image of the meat that is the standard for that grade, and a color image of the meat being bid are quantified and displayed for comparison. In addition, a specific auction screen displayed by the auction app may be configured to display a benchmark meat quality grade, a marbling image showing the marbling condition (marbling) of the meat that serves as the benchmark for that grade, and an inset image showing the marbling condition of the meat being bid in a contrasting manner. Furthermore, on a specified auction screen displayed by the auction app, the standard meat quality grade, a marbling image showing the state of the meat that is the standard for that grade, and a marbling image showing the state of the meat being bid may be quantified and displayed for comparison.

[0097] In the above embodiments, the meat auction system is not limited in any way to the age of the cattle slaughtered. Auction systems to which the present embodiments can be applied include transactions of live cattle, such as carcasses aged 9 months or older (including early-season cattle), live animals aged 8 months or older and fattened for 30 months, carcasses (blocks of meat with the bones removed), and internal organs (various internal organs, so-called offal) extracted from live animals slaughtered. Also included are mother cattle that have given birth multiple times (cattle over 10 years old). The sex of the cattle subject to trading includes all seed cattle, all mother cattle (female cattle), multiparous cattle, female cattle (non-pregnant and single-pregnant cattle), and castrated bulls. Therefore, the meat auction of the present invention is applicable to the trading of all live cattle other than the calves disclosed in Patent Document 1, slaughtered carcasses, and valuable offal that is generated at slaughterhouses. Specifically, this includes carcasses aged 9 months or older (including early-season cattle), live animals that have been fattened for 30 months after birth, carcasses (blocks of meat with the bones removed), and meat extracted from slaughtered live animals (various internal organs, so-called hormones).

[0098] Each step of the present invention can also be realized by executing software (programs) acquired via a network or various storage media on a processing device (CPU, processor) such as a personal computer (computer).

[0099] The present invention is not limited to the above-described embodiments, and various modifications (including organic combinations of the respective embodiments) are possible based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

[0100] In addition, the process for edible meat such as beef and pork is divided into many small steps from receiving live animals to shipping, and there are many items to manage (live information, slaughter information, inspection information, weighing information, grading information, auction information, etc.).However, this embodiment is configured to accumulate and manage live information, slaughter information, inspection information, weighing information, grading information, and auction information inventory management. Therefore, the meat carcass auction system can centrally manage all the information from the time the calf is born to the time it is slaughtered at the auction site and handed over to the purchasing company, which can significantly reduce the burden of management work related to carcasses compared to the past.

[0101] [Fourth embodiment] The meat auction system according to the present embodiment shown in FIG. 1 may be configured to incorporate the following business processes associated with the auction.

[0102] <Settlement processing> This system is configured so that purchase changes can be made while performing settlement operations, as it can simultaneously display purchaser acceptance, changes to successful bid details, and purchaser settlement. This allows the user to check the deposit balance on the deposit balance inquiry screen, and the status of successful bids in the auction can be checked in real time on the auction status inquiry screen.

[0103] <Data management and storage> This system uses SQL Server as its database, which is ideal for developing and operating applications for small-scale servers, allowing it to process large amounts of data at high speed. The management server can also link with multiple PCs to process data registration, dramatically improving business processing efficiency. Furthermore, by using a large-capacity storage device for data backup, auction data can be efficiently backed up, creating a flexible system that can withstand communication failures and preventing data loss due to communication failures. Furthermore, because auction information is managed in a specified table format, highly accurate analysis can be performed using specific applications. Furthermore, because the data stored in the large-capacity storage device can be easily processed, it is possible to provide producers and buyers with information in a unique format on price fluctuations that occur at auctions and the pedigrees of cattle that have been auctioned off at high prices, thereby providing livestock farmers with valuable breeding information and raising awareness in the livestock industry.

[0104] <Mobile auction system> In the first embodiment, a system linked to the market was described, but by making the auction system portable in the event of repairs or renovations to the auction venue, a flexible auction system can be constructed even when the actual auction is held in a temporary venue.

[0105] It is preferable that the size of the auction screen is as large as possible, so by introducing a projector system, it is possible to display live images of carcasses and bid prices to the auctioneers participating in the auction at the venue.

[0106] In addition to the auction date and time, by connecting this system to livestock farms via a network, it is also possible to provide a service that broadcasts video to auctioneers from the birth of a calf in the barn to the processing of the carcass at the slaughterhouse.

[0107] In addition, auctioneers can use small, portable terminals to issue delivery instructions to a shipping company for the carcasses they have won.

[0108] The data setting items that can be executed by this system are not limited to those shown in the above embodiment, but may also include pre-auction deductions, auction date settings, calf auction list data import settings, adult cattle auction list data import settings, auction list data maintenance settings, auction list table, producer special deduction input settings, deduction input settings by entry number, buyer reception settings, buyer reception settings, deposit list table, card seat list table, buyer reception table output, auction operation setting / successful bid content change settings, auction start settings, online auction results settings, online auction information settings, online livestock price settlement settings, auction data inquiry settings, settlement operation settings, buyer settlement settings, settlement list display settings by cooperative agricultural cooperative, settlement list display settings by producer, purchase receivable list display settings, purchase invoice settings by agricultural cooperative, advance alert settings, favorite information input, shipper, pedigree, breed, brand, production area volume, standard unit price, etc. [Industrial Applicability]

[0109] In each of the above embodiments, a carcass auction system has been described in detail, but it is expected that digital auctioning will accelerate in the future as auction systems evolve. Specifically, expectations will be further raised by incorporating this system into all electronic transactions, from the market inspection and bidding on the previous day to the actual auction. For example, steps 1 to 3 are performed during the morning of the previous day. 1: Six-point image capture processing The left side of the loin surface, rib surface, inner surface, entire inside and outside of the oak surface, and in the case of oak, these areas are photographed and stored as digital image data. 2: Data entry process Basic information (listing number, name of fattening prefecture, sender, origin of cattle, lineage (sire / dam's sire), age in months, sex, carcass weight (before / after water-stringing), specifications, bid price, successful bid price, and notes (sick animals, cautions, etc.) are stored as an electronic file. 3: PM - Notification processing after bidding begins By incorporating the sending of bidding information emails to bidders (transmission processing based on overwriting data from other companies), email processing of current price notifications in the evening and at 8:00 on the day, and email processing of promotional emails at the last minute into Auction DX, electronic trading will become even more active. Also, on the day of the auction, steps 4 and 5 will be carried out. Processing notifications after the successful bid in the auction that began at 4:10 (including the successful bid price and payment completion notification), From 5:13, all notification processing to registered users regarding unbidden carcasses was incorporated into Auction DX. As a result, the following effects can be expected in the auction DX system.

[0110] (Market benefits) This will increase the chances of selling carcasses at auction at a higher price. In addition, with meat wholesalers from all over the country participating, it may be possible to sell at a higher price than the general auction price. Furthermore, the product value can be improved (by putting it up for auction, the product value (demand and price) can be determined). In addition, by improving brand power and differentiation, it will be possible to communicate the quality, pedigree, and fattening process of beef to buyers nationwide, rather than just the grading standard price. Furthermore, even if the cattle a producer is offering are an unknown brand, they can still send out auction information to meat traders across the country. Meat dealers across the country can freely participate in the carcass auction, contributing to expanding market share and increasing demand.

[0111] (Benefits for meat wholesalers) Local meat wholesalers can reduce the cost of traveling to the market (fuel costs) and can freely participate in auctions at the national meat market. It also reduces travel costs to the market, hotel fees, and the cost of transporting the carcasses purchased at auction. Furthermore, depending on the bid price, you can bid for the item you want at a price range that is acceptable to you. In addition, since all bidders are given an equal chance to bid on branded beef listed at the auction, the brand image of meat wholesalers can also be enhanced. Furthermore, electronic payment systems are showing signs of further evolution, and in addition to credit card transactions, the payment system of this system may also incorporate virtual currency payments, making it possible to respond to a variety of payment needs. In addition, to accommodate cases where hoteliers, inn operators, and food service centers that purchase large quantities of meat ingredients from meat wholesalers jointly purchase the desired cuts of meat to be processed from carcasses, a system may be constructed that allows the auction screen that can be viewed by the meat wholesalers or a cross-sectional image of the carcass showing the meat quality to be distributed as a video service to the hoteliers, inn operators, and food service centers.
