Description

Method, device and system for issuing security tokens and providing trading platform services for tree trading {METHOD, DEVICE AND SYSTEM FOR ISSUING SECURITY TOKENS AND PROVIDING TRADING PLATFORM SERVICES FOR TREE TRADING}

The following embodiments relate to technology for issuing security tokens for tree trading and providing a platform service for trading issued security tokens and trees.

Trees used in landscaping are classified into various species, including evergreen species (pine, pine, fir, yew, etc.) and deciduous trees (zelkova, cherry, ginkgo, maple, magnolia, etc.). In particular, tree plantation owners (owners) cultivate trees of specific species, and the quantity of trees for each species held is different.

In general, in the trade of trees used for landscaping, there was a problem in that it was difficult for consumers to obtain landscaping trees on time due to the absence of information about suppliers, and in the case of suppliers, there was an issue of uncertainty in sales channels.

In addition, there is a difference between the time when a consumer makes a construction plan for an apartment, institution, park, etc., and the time when the actual planting of trees occurs when a tree transaction is made with a farm owner. Due to the nature of tree transactions, there is a frequent problem that the supplier does not have the quantity of trees at the time of the tree transaction, causing the cost of trees to soar.

Meanwhile, STO (Security Token Offering), a method of raising funds by issuing security tokens in compliance with regulations or exemptions under existing securities laws and regulations, has recently emerged as a new type of means of raising funds, especially in the United States. .

Security tokens play a role in connecting the traditional financial sector with blockchain in terms of allocating assets that already exist in the existing market through tokens. Security tokens represent ownership of a portion of assets and regulate regulation. Transactions must take place within the compliant area. The advantage of STO is that it simplifies procedures, reduces costs, and protects investments when raising funds.

In particular, when trading trees by issuing security tokens, the supplier can predict the demand for trees in advance and prepare funds for tree cultivation in advance, and the consumer can purchase the trees needed in advance in the landscaping plan. By preempting the right to do so, it is expected that problems arising in the existing tree trading market will be resolved.

Accordingly, there is a need to develop technology for issuing security tokens for tree trading and providing platform services for trading issued security tokens and trees.

Figure 2 is a flow chart to explain the process of issuing security tokens and providing trading platform services for tree trading according to an embodiment.

Referring to FIG. 2, first, in step S201, the device 30 may obtain planting plan information about trees from the supplier's terminal 10.

At this time, the planting plan information may include information on the scientific name of the tree to be planted, type of tree, cultivation plan period, land area where the tree will be planted, cultivation area, landscaping contractor or landscaping company to be planted, purpose of planting, number of trees to be planted, etc. However, it is not limited to this.

The device 30 may receive planting plan information about trees from the supplier's terminal 10 and store the received planting plan information in a database.

In step S202, the device 30 may issue a security token for the tree based on the planting plan information and generate token issuance information for the issued security token for the tree.

Here, the process of issuing security tokens includes information on the scientific name of the tree, type of tree, cultivation plan period, land area where the tree will be planted, cultivation area, landscaping contractor or landscaping company to be planted, purpose of planting, etc. By issuing security tokens containing planning information and information about trees, a small fee may be charged in the process of issuing security tokens.

At this time, the token issuance information includes the scientific name of the tree, type of tree, cultivation plan period, land area where the tree will be planted, cultivation area, landscaping contractor or landscaping company to be planted, purpose of planting, etc., and the sales price for the security token. , may include information such as the total amount of tokens issued, but is not limited to this.

According to one embodiment, the device 30 may check the number of trees planned to be planted in a specific land area from the planting plan information and determine the total amount of security tokens issued to correspond to the number of trees.

The device 30 can issue a tree's security token and create the tree's security token as an encrypted digital asset.

According to one embodiment, creating an encrypted digital asset includes generating a unique encrypted digital asset code having an address, a public key, and a private key pair.

According to one embodiment, the encrypted digital asset includes an identifier, which is a unique number assigned to the image. Therefore, encrypted digital assets can be matched one-to-one with images.

In step S203, the device 30 may register token issuance information on the security token trading site.

At this time, the device 30 can register the token issuance information of the security token on the token trading site, thereby allowing the number of security tokens to be traded.

To this end, the device 30 may be connected to a server that provides a token transaction site, or may be implemented including a server that provides a token transaction site.

The device 30 registers the token issuance information of the security token on the token trading site, and issues the traded security token each time the security token is traded through the supplier's terminal 10 and the consumer's terminal 20. Information transaction history can be stored in the database.

In step S204, the device 30 may receive purchase request information for a security token from the consumer's terminal 20.

At this time, the security token purchase request information may include token issuance information corresponding to the tree to be purchased and information on the purchase number of the security token to be purchased, but is not limited thereto.

In step S205, the device 30 may compare the token issuance information and purchase request information and transmit a request for planting a tree to the supplier's terminal 10 based on the comparison result.

According to one embodiment, the device 30 verifies the total issuance amount of security tokens from token issuance information, verifies the purchase number of security tokens from purchase request information, and determines the ratio of the purchase number to the total issuance amount. Token sale ratio can be calculated. If the token issuance rate satisfies a preset standard, the device 30 may transmit a request for planting a tree to the supplier's terminal 10. At this time, the preset standard may be set differently depending on the embodiment.

The device 30 issues a security token for the tree before planting the tree, sells the security token to the supplier, and starts planting the tree when the sales ratio of the security token satisfies a preset standard. By doing so, suppliers can predict the demand for trees in advance, prevent the planting of unnecessary trees with low demand, and secure the funds necessary for planting trees in advance.

The device 30 can issue and sell security tokens before planting trees to evaluate the demand for trees in advance and sell them at an appropriate price, and the supplier can plant trees based on the sales ratio of security tokens. By planting, it is possible to control the supply and demand of trees.

In addition, because this method helps to raise the funds needed for tree planting in advance, suppliers can relieve the burden of financing and allow trees to be planted only when the sales ratio of security tokens meets a certain standard. By doing so, the supply and demand of trees can be balanced. This can help increase the stability of the tree market and ensure suppliers' profits.

In step S206, if it is determined that the tree has been sold, the device 30 may determine the distribution ratio of revenue according to the sale of the tree. At this time, a detailed description of the process of determining the profit distribution ratio will be described later with reference to FIGS. 5 to 7.

When a tree is sold, the device 30 may pay the proceeds from the sale of the tree to a consumer holding a security token corresponding to the sold tree according to the profit distribution ratio.

Security tokens refer to rights related to assets, such as the right to receive profits (dividends, operating profits, etc.) from the asset itself or the legal ownership rights to transfer the asset itself, converted into digital token representation and posted on the blockchain network. can do.

In step S207, the device 30 may pay a dividend determined according to the distribution ratio to the consumer who purchased the security token.

When the dividend to be paid to each consumer is determined according to the distribution ratio, the device 30 receives the account information of each consumer from the consumer's terminal 20 and then remits an amount according to the amount of dividend to be paid to each consumer. It can be handled.

Figure 3 is a flowchart illustrating the process of issuing a new security token according to a tree newly planted in a space where a tree exchanged with an exchange token according to an embodiment was planted.

Referring to FIG. 3, first, in step S301, the device 30 may receive an exchange request from the consumer's terminal 20 for an exchange token that is at least part of a security token held by the consumer and a tree corresponding to the exchange token.

At this time, the exchange token may mean a token that can directly exchange the tree corresponding to the token with the actual tree. The device 30 may provide a service for directly exchanging an exchange token, which is at least a portion of a security token for a tree, and a physical tree corresponding to the exchange token. A small fee may be charged in the process of exchanging exchange tokens for physical trees.

In step S302, device 30 may burn the exchange token.

According to one embodiment, the device 30 deletes the corresponding amount of tokens from the token trading site or moves the security token corresponding to the exchanged tree to a lock-up wallet that is inaccessible on the blockchain, The process of burning the exchange token may be performed, but the process of burning the exchange token may be performed in a different way.

In step S303, the device 30 may distribute the fee paid for the exchange of trees to consumers according to the amount of security tokens held.

For example, the fee paid for the exchange of trees is 10,000 won, the token holdings of the first owner among the owners of the security tokens account for 10% of the total token issuance, and the token holdings of the second owner are 10% of the total token issuance amount. If the ratio of the total amount issued is 25%, the device 30 can distribute a fee equivalent to 1,000 won to the first owner and 2,500 won to the second owner to the consumer.

In step S304, the device 30 may generate a proposal to plant a new tree in the space where the tree exchanged for the exchange token was planted.

The device 30 can identify a land area, which is the space where the tree exchanged for the exchange token was planted, and generate a proposal to plant a new tree in that area.

At this time, the proposal may include information on the scientific name of the new tree, type of tree, cultivation plan period, land area where the tree will be planted, cultivation area, landscaping contractor or landscaping company to be planted, purpose of planting, and number of trees to be planted. A proposal may include information about at least one or more trees.

In addition, the device 30 may further perform a process of determining a new tree to be planted in the space where the tree exchanged for the exchange token included in the proposal was planted.

At this time, the device 30 includes the sales price of the security token corresponding to the tree exchanged for the exchange token, the growth state of the tree, seasonal and weather information corresponding to the time to plant a new tree, the soil condition of the area to be planted, etc. Considering this, at least one tree to be included in the proposal can be extracted from the tree database and the extracted trees can be included in the proposal.

At this time, the tree database may include tree information on the tree's scientific name, type, annual height, circumference, growth conditions, growth environment, tree image, tree price, etc., but is not limited to this.

Specifically, the device 30 may additionally include a tree database or communicate with the tree database wired or wirelessly, and the device 30 may extract tree information from the tree database. Tree information may include information about the scientific name of the tree, type, height by year, circumference, growth conditions, growth environment, image of the tree, tree price, etc.

In step S305, the device 30 may distribute voting rights for the tree planting proposal to consumers according to the amount of security tokens held.

In response to a tree planting proposal, the device 30 determines whether a new tree will be planted in the space where the tree exchanged for the exchange token was planted, depending on the token holding amount of the consumer holding the security token corresponding to the exchanged tree, and whether or not a new tree will be planted. Voting rights, including the right to decide on trees, can be provided to consumers.

In step S306, the device 30 may transmit a request for planting a tree determined by voting rights to the supplier's terminal 10.

When the device 30 receives information about whether a new tree is to be planted in the space where the tree exchanged with the exchange token received from the consumer's terminal 20 was planted and the new tree to be planted, the device 30 plants the tree determined by voting rights. The request can be transmitted to the provider's terminal 10.

In step S307, the device 30 may issue a new security token according to the newly planted tree. The device 30 may repeatedly perform steps S201 to S207 to issue new security tokens according to newly planted trees and provide a service for trading.

In step S308, the device 30 may distribute purchase rights of newly issued security tokens to consumers according to the amount of security tokens held.

The device 30 can provide owners of existing security tokens with the right to preferentially purchase newly issued tokens in proportion to the amount of tokens held.

Accordingly, the device 30 can provide compensation to owners who have already invested by giving owners of existing security tokens the right to purchase new tokens first, and can provide compensation to existing investors in situations where new investors come in. You can ensure that they are not disadvantaged. In addition, it can increase confidence in investment and promote market stabilization.

Additionally, existing owners who have the right to preferentially purchase newly issued tokens will be more likely to purchase and hold the tokens, which can have the effect of increasing the liquidity of security tokens.

In step S309, the device 30 may register unpurchased security tokens among newly issued security tokens on the token trading site.

At this time, the device 30 can register the token issuance information of the newly issued security token on the token trading site, allowing the security token of the newly planted tree to be traded.

To this end, the device 30 may be connected to a server that provides a token transaction site, or may be implemented including a server that provides a token transaction site.

The device 30 registers the token issuance information of the newly issued security token on the token trading site, and whenever the security token is traded through the supplier's terminal 10 and the consumer's terminal 20, the traded security token is registered. The transaction history of token issuance information can be stored in the database.

Figure 4 is a flowchart illustrating a process for generating token issuance information for security tokens of issued trees according to an embodiment.

Referring to FIG. 4, first, in step S401, the device 30 can check the basic price set in advance according to the type of tree from the planting plan information. At this time, the preset basic price may be set differently depending on the embodiment.

The tree database may include information on preset basic prices depending on the type of tree. For example, if the type of tree is a pine tree, the device 30 can check the basic price for the pine tree from the tree database.

In step S402, the device 30 may determine the cultivation weight.

Specifically, the device 30 may check the planting plan period of the tree from the planting plan information and determine a planting weight that is set higher as the planting plan period of the tree is longer. Conversely, the shorter the tree cultivation planning period, the lower the cultivation weight may be set.

The cultivation plan period of a tree is one of the important factors directly related to the value of the tree. Generally, the longer the tree's cultivation plan period, the higher the value of the tree. Therefore, the device 30 increases the cultivation weight as the tree's cultivation plan period is longer. You can decide.

In step S403, the device 30 may determine the land weight.

Specifically, the device 30 can confirm the land area where the tree will be planted from the planting plan information and check the number of local trees, which is the number of trees of the same type as the tree in the area corresponding to the land area.

For example, if the land area where trees will be planted is Gochang-gun, Jeollabuk-do, and the type of tree is pine trees, the device 30 can check the number of local trees, which is the number of pine trees planted in Gochang-gun, Jeollabuk-do.

The device 30 may obtain the past planting details of the land area from the supplier's terminal 10 and check the number of abnormal occurrences, which is the number of times abnormal signs occurred in the land area, from the past planting details.

Past planting history may include, but is not limited to, information including accumulated information on abnormal symptoms occurring in trees, type of abnormal symptom, date of occurrence of abnormal symptom, countermeasures for abnormal symptom, date of resolution of abnormal symptom, etc. .

At this time, abnormal signs include natural disasters including fire, flood, typhoon, dryness, earthquake, avalanche, heavy snow, and tsunami, pests and diseases, animal invasion, yellowing or withering leaves, and wounds on the stem or branches. , may include discoloration of leaves or death of leaves, etc., but this is only a partial example and is not limited to this.

The device 30 may determine a land weight that is set higher as the number of local trees and the number of abnormal occurrences decreases. Conversely, as the number of local trees increases and the number of abnormal occurrences increases, the land weight may be set lower.

The device 30 operates as the number of trees in a region is small, that is, if fewer trees are cultivated in the region, the trees in that region are likely to have a higher price due to limited supply in response to demand in the region. If trees are grown in a region, the land weight can be set higher as the number of trees in the region decreases, reflecting the phenomenon that the value of the trees is likely to increase.

In addition, the device 30 determines that the trees grown in the area are healthy and safe as the number of abnormal occurrences decreases, and the reliability of the quality of the trees corresponding to the area with a low number of abnormal occurrences increases, so the number of abnormal occurrences decreases. The smaller the number, the higher the land weight can be set.

In step S404, the device 30 may determine the provider weight.

The device 30 can receive supplier information from the supplier's terminal 10, and determine the supplier's weight by checking the supplier's number of tree plantings and tree planting period based on the received supplier information.

At this time, the supplier information may include, but is not limited to, information about the supplier's name, contact information, gender, age, number of times the trees were planted, and the tree planting period, which is the period during which the trees were planted.

Based on the supplier information received from the supplier's terminal 10, the device 30 may determine a supplier weight that is set higher as the number of tree plantings by the supplier increases and the longer the tree planting time, and conversely, the number of times the supplier plants trees. The smaller the tree planting time, the lower the supplier weight can be set.

In step S405, the device 30 may determine the sale price for the security token of the tree by applying the cultivation weight, land weight, and supplier weight to the base price.

The device 30 fairly determines the value of the tree security token through the process of checking the preset basic price from the tree database and determining the sales price by applying the cultivation weight, land weight, and supplier weight to the price, Fairness of transactions can be guaranteed.

The device 30 can set an appropriate sales price by objectively considering the actual value of the tree and the conditions under which the tree was grown. Through this, both suppliers and consumers can trade at an appropriate price, increase market stability and reliability, and adjust the cultivation weight, land weight, and supplier weight to more accurately predict the price of tree security tokens. , can help consumers make appropriate investment decisions.

In step S406, the device 30 may compare the planting time of the tree and the time of the customer's security token purchase request from the purchase request information. That is, the device 30 can determine whether the purchase request time is before the planting time or the purchase request time is after the planting time.

In step S407, the device 30 may maintain the sales price if the purchase request time is before the planting time.

In step S408, if the purchase request time is after the planting time, the device 30 checks the cultivation completion time, which is a time after the cultivation plan period from the planting time, and the investment period, which is the period between the purchase request time and the cultivation completion time, is the investment period. The ratio can be calculated.

In step S409, the device 30 may adjust the sales price by applying the investment ratio to the sales price.

The device 30 requires consumers to purchase security tokens of trees and wait until the trees are planted, cultivated, and sold to generate profits. However, if the investment period is not appropriately considered, consumers may be dissatisfied. Accordingly, the device 30 can increase reliability and increase consumer satisfaction by comparing the purchase request time and the planting time, adjusting the sales price according to the investment period, and presenting a fair sales price to consumers. In addition, the longer the investment period, the higher the selling price and thus more profits can be provided to consumers.

Figure 5 is a flowchart for explaining the process of determining the distribution ratio of profits from the sale of trees according to an embodiment.

Referring to FIG. 5, first, in step S501, the device 30 may determine a first ratio including a profit distribution ratio to the supplier and a profit distribution ratio to the consumer. At this time, a detailed description of the process of determining the first ratio will be described later with reference to FIG. 6.

In step S502, the device 30 may determine a second ratio, which is the distribution ratio of revenue between consumers. At this time, a detailed description of the process of determining the second ratio will be described later with reference to FIG. 7.

Figure 6 is a flowchart for explaining the process of determining the first ratio according to one embodiment.

Referring to FIG. 6, first, in step S601, the device 30 can check the number of interests, which is the number of times a keyword related to a tree is mentioned on a tree site.

Tree sites may include, for example, a website distributing trees, a tree community, tree-related news, and SNS content, but are not limited thereto.

The device 30 can calculate the number of interests, which is the number of times a keyword related to a tree is mentioned on a tree site including a website distributing trees, a tree community, tree-related news, and SNS content.

For example, if the tree is a pine tree, keywords related to the tree may include, but are not limited to, trees, pine trees, landscaping, pine trees, evergreen trees, pine pollen, and pine cones. The device 30 may check the number of interests, which is the number of times keywords related to pine trees, including tree, pine tree, landscaping, pine, evergreen, pine pollen, and pine cone, were mentioned on the tree site.

In step S602, the device 30 may check, from the tree database, the average height and average circumference of the tree that is the same as the type of tree and corresponds to the planting plan period.

For example, if the type of tree is a pine tree and the cultivation plan period is 10 years, the device 30 checks the height of a pine tree that has been cultivated for 10 years and is a pine tree from the tree database, calculates the average height, and calculates the circumference. By checking, you can check the average circumference. That is, the device 30 can extract information about the average height and average circumference of pine trees that are pine trees that have been cultivated for 10 years from the tree database.

In step S603, the device 30 may calculate the first number and the second number.

Specifically, the device 30 stores a first number, which is the sales number of trees corresponding to the same height as the average height of the trees, and a second number, which is the sales number of trees corresponding to the same height as the average circumference of the trees, during a preset period. It can be calculated. At this time, the preset period may be set differently depending on the embodiment.

In step S604, the device 30 may determine the demand index of the tree based on the number of interests, the first number, and the second number.

According to one embodiment, the device 30 determines the demand index of the tree to be higher as the number of interests, the first number, and the second number increase, and the lower the number of interests and the first number, the higher the demand index of the tree. 2 The smaller the number, the lower the demand index for trees can be determined.

In step S605, the device 30 may extract a first ratio corresponding to the demand index from a revenue distribution ratio database according to a preset demand index.

At this time, the profit distribution ratio database may include distribution ratio information about the distribution ratio of profits to suppliers and the distribution ratio of profits to consumers according to the demand index.

Specifically, the device 30 may additionally include a revenue sharing ratio database or communicate with the revenue sharing ratio database wired or wirelessly, and the device 30 may extract information about the revenue sharing ratio from the revenue sharing ratio database. there is.

The profit distribution ratio database may store distribution ratio information about the distribution ratio of profits to suppliers and the distribution ratio of profits to consumers, matched according to the demand index.

For example, if the demand index is 1 or more but less than 10, the distribution ratio of profits to suppliers and consumers is 3:7, and if the demand index is 11 or more but less than 20, the distribution ratio of profits to suppliers and consumers is 3:7. If the distribution ratio of profits to suppliers is 4:6 and the demand index is 21 to 30, the distribution ratio of profits to suppliers and to consumers is 5:5, and if the demand index is 31 to 40, suppliers The distribution ratio of profits to suppliers and the distribution ratio of profits to consumers is 6:4, and if the demand index is more than 41, the distribution ratio of profits to suppliers and profits to consumers is set to 7:3 to distribute profits. It may be stored in a ratio database.

At this time, if the demand index of a specific tree is 37, the first ratio can be determined as the distribution ratio of revenue to suppliers and revenue to consumers as 6:4.

The device 30 calculates the demand index of the tree and determines the distribution ratio of revenue to the supplier and the distribution ratio of revenue to the consumer based on the demand index, thereby enabling fair distribution of profits between suppliers and consumers. This can help you maintain balance.

In step S606, the device 30 may obtain an image of the tree taken from the camera of the supplier's terminal 10, analyze the image of the tree, and confirm the actual height and actual circumference of the tree.

The device 30 can analyze the image of the tree taken from the camera installed in the supplier's terminal 10, extract the characteristics of the tree, and confirm the actual height and circumference of the tree based on the characteristics. The device 30 can process tree images using computer vision technology and determine the size and shape of the tree by applying an object recognition algorithm. However, since this process is self-evident to those skilled in the art, a detailed description will be omitted. Do this.

In step S607, the device 30 may calculate the first difference value and the second difference value.

Specifically, the device 30 may calculate a first difference value between the actual height and the average height and a second difference value between the actual perimeter and the average perimeter.

In step S608, the device 30 may adjust the first ratio according to the first difference value and the second difference value.

The device 30 calculates the difference between the actual size of the tree and the average size through the first difference value and the second difference value, measures the relative size of the tree, and distributes profits between the supplier and the consumer accordingly. The ratio can be adjusted.

For example, if the size of the actual tree is larger than the average size, the device 30 adjusts the profit distribution ratio to the supplier higher because the value of the tree increases, and conversely, if the size of the actual tree is larger than the average size, the device 30 If it is smaller, the value of the tree is relatively lower, so the profit distribution ratio can be adjusted higher to the consumer. In this way, the device 30 can increase the fairness of tree transactions and improve the reliability of transactions by adjusting the distribution ratio of profits.

Figure 7 is a flowchart for explaining the process of determining the second ratio according to one embodiment.

Referring to FIG. 7, first, in step S701, the device 30 can check the number of security tokens purchased by the consumer from the consumer's purchase request information.

In step S702, the device 30 may check the consumer's investment period from the consumer's purchase request information.

In step S703, the device 30 may determine the second ratio in proportion to the number of purchases and investment period for each consumer.

The device 30 can determine the profit distribution ratio according to the sale of trees by calculating a second ratio that ensures that purchasers are fairly guaranteed to receive the same amount of profit as they have invested.

Figure 8 is a flowchart for explaining the process of adjusting the abnormality rate according to one embodiment.

Referring to FIG. 8, first, in step S801, if a tree is installed in the first company, the device 30 checks the date on which an abnormality symptom occurred in the tree based on the history of abnormality symptom occurrence of the tree, and determines the date of occurrence of the abnormality symptom in the tree. The cycle of occurrence of symptoms can be analyzed. To this end, the device 30 can store and manage abnormal symptom occurrence history classified by tree in a database and obtain the abnormal symptom occurrence history of each tree from the database. The abnormal symptom occurrence history may be composed of a list of information including accumulated information on abnormal symptom details occurring in trees, the type of abnormal symptom, the date of occurrence of the abnormal symptom, the countermeasures for the abnormal symptom, and the date of resolution of the abnormal symptom.

At this time, signs of tree abnormalities include natural disasters such as fire, flood, typhoon, dryness, earthquake, avalanche, heavy snow, and tsunami, pests and diseases, animal invasion, yellowing or withering leaves, and wounds on the stem or branches. If present, this may include discoloration of leaves or death of leaves, but this is only a partial example and is not limited thereto.

For example, if it is confirmed that an abnormal symptom occurred on January 1 and January 11 based on the tree's abnormal symptom occurrence history, the device 30 can analyze the occurrence cycle of the abnormal symptom at 10-day intervals. there is. At this time, if the device 30 determines that an abnormality has occurred several times during a preset period (e.g., the last 6 months), it checks how often the abnormality occurs on average and analyzes the occurrence cycle of the abnormality. You can.

In step S802, the device 30 may predict the expected date of occurrence of the abnormal symptom in the tree, based on the occurrence cycle of the abnormal symptom.

For example, if the device 30 determines that the occurrence cycle of abnormal signs is every 10 days and that the most recent abnormal symptom occurrence date in the tree is confirmed to be January 5, the abnormal symptom is expected to occur in the tree. The expected date of onset of symptoms is January 15th.

In step S803, the device 30 may check the number of days remaining until the expected date of abnormal symptom occurrence as the first date.

For example, if the expected occurrence date of the abnormal symptom is predicted to be January 15th and the current date is confirmed to be January 13th, the device 30 may confirm the first date as the 2nd.

In step S804, the device 30 may check whether the first date is included in the first reference range. Here, the first reference range may be set differently depending on the embodiment.

If it is confirmed in step S804 that the first date is included in the first reference range, in step S805, the device 30 may determine that adjustment to the first incidence rate is not necessary.

For example, if the first reference range is set from 5 to 10 days, the device 30 may determine that adjustment for the first incidence rate is not necessary if the first date is confirmed to be the 7th. .

If it is confirmed that the first date is outside the first reference range in step S804, the device 30 may check whether the first date is less than the minimum value of the first reference range in step S806.

If the first date is confirmed to be smaller than the minimum value of the first reference range in step S806, the device 30 may adjust the first incidence rate to a value obtained by multiplying the first set value and the first incidence rate in step S807. At this time, the first set value can be set within the range from 1 to 2.

For example, if the first reference range is set to 5 to 10 days, the first set value is set to 1.5, and the first incidence rate is predicted to be 20%, device 30 sets the first date to 10 days. If is confirmed to be 3 days, 30%, which is the product of the first set value and the first incidence rate, is calculated, and then the first incidence rate can be adjusted from 20% to 30%.

That is, if the device 30 determines that the first date is outside the first reference range and is smaller than the minimum value of the first reference range, the device 30 sets the first date as the value multiplied by the first set value set within the range from 1 to 2 and the first incidence rate. 1 By adjusting the incidence rate, if the remaining period until the expected date of abnormal symptom occurrence is very short, below a certain period, the first incidence rate can be adjusted to a higher value using the first set value.

If the first date is confirmed to be greater than the minimum value of the first reference range in step S806, since the first date is outside the first reference range, it may be confirmed that the first date is greater than the maximum value of the first reference range, If the first date is confirmed to be greater than the maximum value of the first reference range, in step S808, the device 30 may adjust the first incidence rate to a value multiplied by the second set value and the first incidence rate. At this time, the second set value can be set within the range from 0 to 1.

For example, if the first reference range is set to 5 to 10 days, the second set value is set to 0.5, and the first incidence rate is predicted to be 20%, device 30 If is confirmed to be 12 days, 10%, which is the product of the second set value and the first occurrence rate, is calculated, and then the first occurrence rate can be adjusted from 20% to 10%.

That is, if the device 30 determines that the first date is outside the first reference range and is greater than the maximum value of the first reference range, the device 30 multiplies the second set value set within the range from 0 to 1 by the first incidence rate. By adjusting the first incidence rate, if the remaining period until the expected date of abnormality occurrence is very long, longer than a certain period, the first incidence rate can be adjusted to a lower value using the second set value.

The device 30 can increase the efficiency of tree management by analyzing the occurrence cycle of abnormal signs and predicting the expected date of abnormal symptom occurrence in the tree. The device 30 can take preventive measures in advance or adjust the inspection cycle by predicting the expected date of occurrence of abnormal symptoms, thereby improving the quality of trees, solving preventable problems, and reducing unnecessary tree management and inspection costs. , it is possible to determine an appropriate inspection cycle, thereby increasing efficiency and economic efficiency in tree management.

The device 30 provides a security token issuance and trading platform service for tree trading, providing a basis for suppliers to make appropriate business plans and conduct production and purchasing activities based on the issuance information of security tokens for trees. , it is much easier to secure sales channels and purchasing networks, and thus achieve the effect of improving the profitability of the business. Furthermore, by predicting the demand for trees, we can prevent imbalances between supply and demand for trees in the future, allowing trees to be traded at a stable cost.

In addition, stable prices can further revitalize the tree market, and by identifying market demand and planning tree planting, suppliers can provide a variety of high-quality landscaping trees, and consumers can secure high-quality landscaping trees in advance.

The device 30 provides a security token issuance and trading platform service for tree trading, so that suppliers can cultivate trees more stably by securing consumers in advance, and can grow trees more stably through the sale of tree security tokens. As you grow, you can collect the necessary expenses in advance.

Unlike producing specific products such as industrial products or food, growing trees requires a relatively long period of time, so suppliers can attract the funds necessary for tree cultivation in advance based on tree security token transactions. It ensures stable demand by planning in advance at a certain point in the future.

In addition, individual investors among consumers can make investments in the tree market, which is expected to grow steadily in the future, at a low cost based on security tokens for trees.
