The AI and blockchain-based warehouse use system (S) according to an embodiment of the present invention is a blockchain and artificial intelligence (AI) in which a plurality of nodes are connected through a communication network (a communication network including at least one of a wired communication network and a wireless communication network). ), which will be referred to as 'this system' for convenience of description below.

Blockchain technology, a distributed ledger technology, is a technology in which computer devices participate and jointly maintain a complete distributed database. Blockchain technology is characterized by decentralization, scalability and transparency. Each computer device can participate in a database record, and database synchronization between them can be quickly implemented.

Blockchain is a P2P network layer based on the gossip protocol, a consensus algorithm that agrees on common data between distributed nodes, and (3) a Merkle tree type that stores the agreed state. It consists of a data structure, (4) a digital encryption algorithm to ensure the identity of the account and the safety of recorded information. Blockchain can be described as an append-only infinite state machine that uses transactions to change state, combining the above four elements.

Blockchain is a well-known technology used in various fields, and a detailed description thereof will be omitted.

Referring to FIGS. 1 to 3 , the present system (a blockchain-based warehouse use system (S) according to an embodiment of the present invention) includes a plurality of warehouse owner terminals 1 and user terminals 2.

The warehouse owner terminal 1 is a node of the blockchain (participating as a node of the blockchain), and generates a data block including warehouse information and stores it in the blockchain (stored in nodes) (see FIG. 3). (see S1)). A plurality of the warehouse owner terminals 1 may be provided in this system.

The warehouse owner terminal 1 is a terminal (eg, a smartphone, tablet, PC, etc.) used by the warehouse owner, and the warehouse owner terminal 1 is an input module (eg, a touch screen) of the warehouse owner terminal 1 etc.), the warehouse information is received and a data block including the warehouse information is created.

Here, the warehouse information may include the location of the warehouse, availability by time zone, usage cost, warehouse owner information, warehouse size, and the like.

The warehouse owner terminal 1, the user terminal 2, and the operator terminal 3, which will be described later, are applied with various control configurations (eg, various electronic devices or electronic modules such as computers and processors) known to those skilled in the art. can Exemplarily, each of the warehouse owner terminal 1, the user terminal 2, and the operator terminal 3 described later uses a signal or command generated according to a program or algorithm included in the warehouse owner terminal 1. , It may be configured to transmit to each of the user terminal 2 and the operator terminal 3, which will be described later. For example, the warehouse owner terminal 1, the user terminal 2 and the operator terminal 3 described later are provided separately, and the warehouse owner terminal 1, the user terminal 2 and the operator terminal described later are separately provided. (3) It can be connected with each wired or wirelessly.

As described above, since the warehouse owner terminal 1 is a node of the blockchain, a data block including warehouse information can be stored (registered) in the warehouse owner terminal 1.

1 to 4, the user terminal 2 is a block chain node (a node participating in the block chain), and a plurality of warehouse information stored in the block chain (from each of the plurality of warehouse owner terminals 1) The input warehouse information) is classified by region and the generated classification information is output.

The warehouse owner, user, operator, transporter, etc. using the warehouse owner terminal 1, the user terminal 2, the operator terminal 3 to be described later, and terminals that are other nodes (for example, transporter terminals) use a private key, It is possible to access the data block stored in the block chain by using a passcode or the like.

Like the warehouse owner terminal 1, the user terminal 2 may be a smart phone, a tablet, a PC, or the like, and may be used by a shipper who is a warehouse user.

It was said that the classification information was created by classifying warehouse information stored on the block chain by region. One or more of the transporter terminals may be created, and the data block including the classification information may be registered and stored on the blockchain.

The user terminal 2 may receive the classification information and output it through an output module (eg, a display device).

More specifically, the system may further include an operator terminal 3, which is a node of a block chain, and the operator terminal 3 may be a terminal used by an operator (manager) in the system.

At this time, one or more of the warehouse owner terminal 1, the user terminal 2, and the operator terminal 3 may generate a data block including map information indicating a plurality of regions and store it in the blockchain.

At this time, the user terminal 2 inputs an output unit (component corresponding to the output module) for receiving and outputting the map information, and a selection signal for selecting one of a plurality of regions (hereinafter, the first region) from the map information. An input unit (component corresponding to the input module) that receives and generates selection information, and a matching unit that receives the selection information and transmits classification information corresponding to one of a plurality of regions (first region) to the output unit. .

The output unit receives and outputs the classification information. Since the classification information includes warehouse information by region, the output information can output warehouse information of the first region (see (S2) and 4 in FIG. 3). .

In this way, the present system has the advantage of including the user terminal 2 that outputs warehouse information for each region, so that the user can grasp the status and availability of warehouses for each region.

In particular, since the user terminal 2 includes the output unit, the input unit, and the matching unit, there is an advantage that the user can select a region on the map and grasp warehouse information.

As described above, the classification information may be generated by one or more of the warehouse owner terminal 1, the user terminal 2, the operator terminal 3 described later, and the transporter terminal. It also has the advantage of being able to grasp warehouse information by region at the same time.

This system has the advantage of excellent security because it is difficult to forge/falsify data by hacking because various information including warehouse information is distributed and stored in nodes of the blockchain, so a central server such as a financial institution is not required.

On the other hand, the user terminal 2 may further include a reservation unit for receiving reservation information regarding warehouse use from the input unit, generating a data block including the reservation information, and storing it in a block chain.

The reservation information may include information such as warehouse information including an identification number of the warehouse, time zone, user personal information, stored goods, payment status, and the like.

As such, the present system has an advantage in that a user can reserve a warehouse by identifying a warehouse state by region, including a reservation unit. In addition, as described above, since reservation information is stored in the block chain, warehouse owners across the country also have the advantage of being able to utilize this data as they can determine whether or not a warehouse is reserved by region.

In addition, since the transporter terminal, which is another node (4) of the block chain used by the transporter and described later, can also output the above reservation information, there is also an advantage that the transporter can grasp reservation information and warehouse information in real time.

1 to 6, at least one of the warehouse owner terminal 1, the user terminal 2, and the operator terminal 3 includes the departure location location information input from the user terminal 2 and the It may include a calculation unit that calculates the moving distance using the warehouse information.

The calculation unit calculates the distance from the departure point to the destination (warehouse location) by converting the GIS (Geographic Information System)-based route network into coordinate data by applying a linear/rectangular/elliptical model and introducing the concept of ITS (Intelligent Transportation System). can

The GIS (Geographic Information System) described above is a computer system for capturing, storing, querying, analyzing and displaying geospatial data.

The calculation unit may visualize a map using a stochastic set-covering method.

The calculation unit can find the optimal vehicle route for each warehouse by receiving requirement information from the user terminal 2 used by the shipper (user) and allocating regions (region allocation algorithm) in consideration of the requirement information.

In addition, the calculation unit may search for an optimal path from the starting point to the destination using the A-star algorithm.

That is, the calculation unit may calculate the moving distance using information on the location of the starting point input through the input unit of the user terminal 2 and the location (destination) of the warehouse included in the warehouse information.

In addition, the calculation unit may calculate the transport cost using the moving distance and the operating cost of the freight vehicle.

The calculation unit calculates the travel distance (optimum travel distance) from the starting point to the destination through one or more of GIS, ITS, stochastic set-covering method, A-star algorithm, and area allocation algorithm, and calculates the travel distance and the operation of the freight vehicle. Transportation cost can be calculated using cost.

Exemplarily, the moving distance from the starting point to the destination is 3 km, and the transportation cost can be calculated by considering the fuel efficiency and labor cost (operating cost) of a cargo vehicle per 1 km in a specific time period.

Of course, the information including the travel distance and the transportation cost can be stored on the blockchain as well.

At least one of the warehouse owner terminal 1, the user terminal 2, and the operator terminal 3 may generate recommendation information recommending one of a plurality of warehouses using the transportation cost and the warehouse information. can The user terminal 2 may receive the recommendation information and output it through an output unit (output module).

The recommendation unit may calculate a final cost by summing the transportation cost and the usage cost included in the warehouse information, and recommend a warehouse having the lowest final cost.

Through this, there is an advantage that the user (shipper) can reserve the warehouse in consideration of cost.

Transporter terminals participating as the other nodes may also include the above calculation unit and recommendation unit.

This system (eg, one or more of the warehouse owner terminal (1), user terminal (2), and operator terminal (3)) is designed with a server (blockchain node) as a quadruple high-availability architecture (Scale Out method) You can prepare for high traffic by processing a large number of warehouse information. In other words, when a failure occurs in one availability zone, it is possible to minimize failure recovery by separating functions and increase operational efficiency by allocating them to operation, development, and test zones.

In addition, this system (eg, one or more of the warehouse owner terminal (1), user terminal (2), and operator terminal (3)) automatically expands and contracts the server according to the amount of user access using auto scale to prevent server failure. can be prevented in advance.

In addition, this system (eg, one or more of the warehouse owner terminal (1), user terminal (2), and operator terminal (3)) divides the data received when the user accesses data into network area hierarchies and receives them in a more seamless structure. By regularizing (CloudFront function) so that it can come, you can speed up data access.

In addition, this system (eg, one or more of the warehouse owner terminal (1), user terminal (2), and operator terminal (3)) uses the Amazon RDS design to distribute data to multiple servers to backup, store, and restore data Loss problems can be prevented.

In addition, the system (eg, one or more of the warehouse owner terminal 1, the user terminal 2, and the operator terminal 3) may provide notification and subscription services when the reservation information is generated using Amazon SQS.

7 is a diagram for explaining the hierarchy of a block chain. Figure 8 is a schematic flow chart for explaining data in a block chain and the data going to an access device.

The existing material blockchain was created as a permissioned blockchain based on Hyperledger Fabric. Overseas, the scalability of individual servers in the fabric is low, and the number of nodes that operate reliably consists of 4 to 8 on average. The problem with large-scale services is that they cannot be flexibly accommodated according to the size of customers.

Referring to FIGS. 1, 7, and 8, this system (eg operator terminal 3, etc.) uses Tendermint Core as a blockchain construction engine to compensate for the above-mentioned problems of the Hyperledger Fabric-based permissioned blockchain. engine was adopted.

The Tendermint core engine described above can process thousands of transactions per second. To be more specific, hundreds of hours of development work can be reduced by providing the networking and consensus layer, which is a large block chain structure, as a basic engine. .

More specifically, the Tendermint Core engine is connected to the application through the Application Blockchain interface (ABCI) socket protocol. It helps nodes propagate transactions and validates validators for new transactions to be added to the blockchain. The structure of the validator is determined by the application. In this system, a private Proof of Authority blockchain is built using several pre-determined validators. In this system, the data block is configured as a permissioned blockchain that can be managed only by authorized users.

This system can be composed of a total of five layers: network layer, consensus layer, contract layer, and application layer.

The data layer is a layer that encapsulates basic data blocks and related data encryption technologies. Each data block usually includes a block head and a block body, and the block head encapsulates and concatenates the hash value of the previous block. The block body contains several pairs of transaction information of the current block.

The network layer includes the system's network mode (P2P distributed network), data transmission protocol and verification mechanism.

Consensus layer consists of a consensus mechanism to prove a node's computing power and workload. In this system, the blockchain verifies the workload with the PoA consensus algorithm.

The smart contract layer operates blockchain transaction protocols and data blocks. Transaction information results of transport companies, users, transport drivers, warehouse owners, and operators are shared through smart contracts.

The application layer manages and tracks data in real time by linking blockchain and programs (warehouse terminal (1), user terminal (2), operator terminal (3), etc.).

In this way, the block chain of this system is built through the Tendermint core engine, which has the advantage of improving the efficiency of processing large amounts of data blocks.

1, 11 and 12, the recommender may generate detailed recommendation information recommending one of a plurality of warehouses using the warehouse information and user information through a preset artificial intelligence (AI) algorithm. there is.

More specifically, the plurality of user terminals 1 creates a data block containing user information including user profiles, text input information, purchase details, reservation information, and warehouse evaluation information, and stores the information on the block chain. can be saved

Here, the user's profile means the user's identification information (name, age, phone number, etc.), and the text input information means words (text) input by the user through the input unit of the user terminal. In addition, the purchase details refer to details of purchases of goods by a user connecting to an Internet network through a user terminal.

The evaluation information on the warehouse may mean ratings, star ratings, and the like as reviews after using the warehouse.

The above text input information may be generated by Equation 1 below of term frequency - inverse document frequency (TF-IDF).

[Equation 1]

In Equation 1 above, TF (term frequency) is a value indicating how often a specific word appears in a document. The higher this value is, the more important it is in the document, and is calculated by Equation 2 below.

[Equation 2]

However, if the word itself is frequently used in a document group, this means that the word appears frequently. This is called DF (document frequency), and the reciprocal of this value is called IDF (inverse document frequency) (calculated by Equation 3). TF-IDF is the product of TF and IDF.

[Equation 3]

Since TF-IDF is well known, a detailed description thereof will be omitted.

The recommendation unit classifies the user information by type through a preset artificial intelligence algorithm to generate classification information, and recommends one of a plurality of warehouses using the classification information, the user information, and the warehouse information. can be created and stored on the blockchain.

Exemplarily, the recommendation unit may classify user information by classifying purchase details by type. Exemplarily, the classification information may be generated by classifying users who mainly purchase food and users who mainly purchase clothing. .

Afterwards, the recommendation unit may classify users by type and then match the evaluation information of users by type to classify the evaluation information by type.

Therefore, when the new user later uses the system, the recommendation unit classifies the new user by type using the purchase history of the new user and extracts evaluation information matching the classification information to predict the evaluation of the new user's warehouse, It is possible to generate detailed recommendation information recommending one of a plurality of warehouses.

For example, the recommendation unit may generate the detailed recommendation information by predicting the user's evaluation of the warehouse through Equation 4 below.

[Equation 4]

The above equation rx is the evaluation vector of user x, and assuming that N is a set of k similar users evaluated by item i (warehouse), the user's evaluation of the warehouse can be predicted.

The above Equation 4 is known, and a detailed description thereof will be omitted.

The artificial intelligence algorithm including the above equations and used by the recommender is commonly used in various fields, and a more detailed description thereof will be omitted.

In this way, the present system generates detailed recommendation information recommending one of a plurality of warehouses using classification information, user information, warehouse information, etc., and thus has the advantage of being able to recommend a warehouse more suitable for a user among a plurality of warehouses. there is.

Hereinafter, a warehouse use method (hereinafter referred to as 'this method') according to an embodiment of the present invention will be described. However, since this method is a warehouse use method using the above-described system and includes the same or corresponding technical features as the present system described above, the same reference numerals are used for the same or similar configurations as the salpin configuration above, and overlapping descriptions should be shortened or omitted.

Referring to FIGS. 1 to 3 , the method includes a step (S1) of generating a data block including warehouse information through the warehouse owner terminal 1 and storing it in a block chain, and through the user terminal 2 and outputting classification information generated by classifying a plurality of warehouse information by region (S2).

1 to 4, the method includes outputting the map information through an output unit (S21) and generating selection information for selecting one of a plurality of regions from the map information through an input unit (S22). ), receiving the selection information through the matching unit and transmitting classification information corresponding to one of a plurality of regions to an output unit (S23), and outputting the classification information through the output unit of the user terminal 2. (S24) may be included.

The method may include generating a data block including reservation information on warehouse use through a reservation unit and storing it in the blockchain (S30).

In addition, the method calculates the travel distance using the starting location location information and warehouse information input from the user terminal 2 through the calculation unit, and calculates the transportation cost using the travel distance and the operating cost of the freight vehicle (S40). can include

In addition, the method may include a step of recommending one of a plurality of warehouses using the transportation cost and the warehouse information through a recommendation unit (S50).

The method includes a step (S3) of recommending one of a plurality of warehouses using the user information and the warehouse information.

The step (S3) may be performed by the above recommendation unit. Detailed recommendation information recommending one of a plurality of warehouses may be generated using the user information and the warehouse information.

9 is a diagram for explaining a state in which dotted lines are output in an additional embodiment of the present invention. 10 is a diagram for explaining filling icons in an additional embodiment of the present invention.

Referring to FIGS. 1, 4, 9, and 10, the user terminal 3 requires a situation in which a specific part of the terminal screen (output module) needs to be enlarged and viewed in detail. For example, when trying to see warehouse information (eg "A" in FIG. 9, the specific part) in a larger size on the output screen of the terminal, it is necessary to enlarge the area including the warehouse information part as much as possible.

In particular, there is a need to expand a specific area to the elderly with presbyopia.

To meet the above needs, the user terminal 3 may include a client including an enlargement interface that enlarges a selected area on the terminal screen (the client may be installed).

Conventionally, when you want to enlarge a specific area, you tap the touch screen (terminal screen) several times or adjust the distance between the two fingers while touching the touch screen with two fingers (for example, thumb and index finger) to size the screen. A method of controlling was used.

If you tap the touch screen several times, not only the part you want to see enlarged but also other parts are enlarged, so it was often impossible to check the part you wanted to check on one screen, so moving the screen had to be accompanied. .

In addition, there is a problem that it is difficult to hold a terminal (eg, a smartphone, etc.) when adjusting the distance between the two fingers while touching the touch screen with two fingers.

In addition, terminals having a large size have recently been used, and in particular, users with small hands have difficulty in gripping the terminal because it is difficult to enlarge a specific part with only one finger.

The enlargement interface is intended to overcome the problems of the conventional method, and allows an area to be enlarged to be displayed on one screen, but enlarged using one finger. That is, while enlarging a desired specific part through this, it is possible to effectively suppress damage to the terminal by making it easier to hold the terminal.

Hereinafter, the magnification interface will be described in more detail. Referring to FIG. 9, when an arbitrary point on the terminal screen is touched for the first time (touching the terminal screen with a finger, etc.) and the touch state is maintained for a preset time (eg, 3 seconds), a starting point Z1 is output, and the starting point When the touch (Z1) is released and then touched again (touched again) after a preset time (eg, 3 seconds), an inner dotted line (Z2) surrounding the starting point (Z1) may be output.

Conversely, when the touch of the starting point Z1 is released and a re-touch is performed for a predetermined time or less, or a point other than the starting point Z1 is touched on the terminal screen, the starting point Z1 may be deleted.

In addition, when the touch of the starting point Z1 is maintained for a predetermined time after the inner dotted line Z2 is output, the enlarged interface outputs an outer dotted line Z3 surrounding the inner dotted line Z2. can

In this case, the shape of the inner area Z21 formed by the inner dotted line Z2 and the outer area Z31 formed by the outer dotted line Z3 may correspond to a reduced shape of the terminal screen.

As shown in [B] of FIG. 9, the enlarged interface surrounds the outer dotted line Z3 when the touch of the starting point Z1 is maintained beyond a preset time after the outer dotted line Z3 is output. Of course, the outermost dotted line Z4 can be output. That is, the number of dotted lines output according to the touch time of the starting point Z1 is not limited.

Referring to [A] of FIGS. 9 and 10 , the magnification interface is such that a first point (any point within the inner region Z21) within the inner region Z21 exceeds a preset time (eg, 3 seconds). When touched, a first filling icon Z22 covering the inner region Z21 may be output.

In addition, the enlargement interface is dragged from the first point to the area between the inner dotted line Z2 and the outer dotted line Z3 (hereafter referred to as an area between) (drag while a finger touching a terminal screen such as a touch screen touches the screen) ), the second filling icon Z32 covering the outer region Z31 may be output.

Similarly, when the outermost dotted line (Z4) is output, the enlarged interface is dragged between the inner dotted line (Z2) and the outer dotted line (Z3), and the third fill icon can output

The above-described fill icons (first fill icon Z22, second fill icon Z32, etc.) may illustratively have translucent colors.

After becoming the second fill icon Z32, that is, when the area between the inner dotted line Z2 and the outer dotted line Z3 is touched and dragged to the inner area Z21, the second fill icon Z32 It is deleted and the first filling icon Z22 may be output.

When the first fill icon Z22 is output (refer to [A] in FIG. Y), the enlarged interface displays the inner region Z21 as the touch of the first fill icon Z22 is released and touched again. It can be enlarged by a set magnification (see [C] in FIG. 10).

If the second fill icon Z32 is output (refer to [B] in FIG. 10 ), the touch of the second fill icon Z32 is released and the outer area Z31 is enlarged by a preset magnification as the second fill icon Z32 is touched again. can

Here, the preset magnification is a magnification that is the maximum size within the limit that the selected area (inner area (Z21) or outer area (Z31)) on the terminal screen can be displayed on one screen (eg, 2 times and 3 times, respectively). ) can be.

In this way, by including the magnification interface, the present system has an advantage in that a specific area can be enlarged with only one finger while holding the terminal with one hand, even if the terminal is large and the size of the hand holding the terminal is small.

More specifically, the area to be enlarged is displayed by adjusting the touch duration of the starting point Z1 with one finger and outputting dotted lines only by touching/re-touching (touching again). You can preview it just by moving your finger.

In addition, since the starting point Z1 is an arbitrary point where the user selects the screen of the terminal, it is possible to touch and set a specific part to be enlarged with only one finger while holding the terminal. Through this, there is an advantage in that a separate operation for operating the enlargement interface is not required because a separate start icon for generating the starting point Z1 is not required.

In addition, as described above, since the starting point (Z1) is output only when the touch state is maintained for a preset time after the first touch, it is possible to prevent an erroneous operation in which a portion is enlarged by touching the terminal screen in an unintentional motion, and the user can use the inner dotted line (Z2) It can be confirmed whether the touch state is maintained beyond a preset time after touching the starting point (Z1) again through the presence or absence of the output of .

In addition, in the state in which the malfunction is suppressed in the above manner, the user does not release the touch of the starting point Z1 and touches it again, but only maintains the touch time of the starting point Z1 to reach the outer region Z31. , you can easily enlarge and preview a specific area to be enlarged by outputting it, and output it.

Also, as described above, since the inner region Z21 and the outer region Z31 have a reduced shape of the terminal screen, when the inner region Z21 or the outer region Z31 is enlarged, it is maximized according to the shape of the terminal screen. The user can determine in advance how much of a specific part is included in the area to be enlarged (the inner area Z21 or the outer area Z31) before the inner area Z21 or the outer area Z31 is enlarged. There is an advantage to being

That is, when the inner region Z21 is output, the part to be enlarged may not be included in the inner region Z21, and the user can check this through the inner region Z21 in which the terminal shape is reduced, so that the starting point ( By making the touch of Z1) longer, the output of the outer area Z31 can be induced.

In addition, the area to be output (the inner area Z21 or the outer area Z31) can be set only by the operation of dragging from the first point to the in-between area and the operation of dragging from the in-between area to the inner area Z21. However, since the outer area Z31 and the inner area Z21 are reduced areas on the terminal screen, the in-between area is formed along the circumference of the terminal, and the starting point Z1 is farther from the circumference of the terminal than the in-between area. As it is arranged, there is an advantage in that it is possible to conveniently select an area to be output with one finger because it is possible to move to a convenient arbitrary point among the areas between the terminals even when holding the terminal with one hand.

Through this, even if the outer dotted line (Z3) is output by unintentionally touching the starting point (Z1) for a longer time, the inner dotted line (Z2) can be set as the enlarged area without the operation for deleting the outer dotted line (Z3). There is an advantage.

In addition, since the colors of the fill icons (the first fill icon Z22 and the second fill icon Z32) are translucent, it is possible to visually check the specific part to be enlarged even after they are output.

In addition, since the filling icons enlarge the inner region Z21 or the outer region Z31 when the touch is released and re-touched, there is an advantage in that expansion of the selected region due to an erroneous operation can be suppressed.

The present invention described above with reference to the accompanying drawings can be variously modified and changed by those skilled in the art, and these modifications and changes should be construed as being included in the scope of the present invention.
