The present invention relates to a blockchain-based art brokerage service providing system that is linked to an IoT storage, and provides a platform that can be shared in real time by controlling and monitoring the storage environment when storing art.

The types of goods traded in accordance with the changes in modern consumption patterns are rapidly increasing as the sharing economy contract method such as sharing-oriented rental lease spreads from the ownership-oriented sales contract type. Consumers have gained the advantage of being able to use desired service goods at a more reasonable price, but in the case of goods such as artworks and creations, it is difficult for consumers to determine the appropriate value of the goods, and the professionalism and reliability of the contract itself are guaranteed due to the diversified contract method. Difficulty problems also arise. If a broker with expertise in the type of goods makes an appropriate value judgment and mediates appropriately for the contract process, both the seller and the buyer can conclude a reliable contract. As access to various goods has improved, if the sharing platform develops, the sharing economy market can develop more stably than it is now.

At this time, a method for mediating works of art was researched and developed.

Figure 2 is a block diagram for explaining the art brokerage service providing server included in the system of Figure 1, Figure 3 is a block chain-based art brokerage service linked with the IoT storage according to an embodiment of the present invention is implemented It is a drawing for explaining an embodiment.

Referring to FIG. 2 , the art brokerage service providing server 300 includes a registration unit 310 , an inspection unit 320 , a storage unit 330 , a sharing unit 340 , an interlocking unit 350 , and a log unit 360 . , a control unit 370 , and a recommendation unit 380 .

It means a program that receives and displays hypertext written in HTML (hyper text mark-up language), for example, Netscape. , Explorer, Chrome, etc. In addition, the application means an application on the terminal, for example, includes an app (app) executed in a mobile terminal (smartphone).

Referring to FIG. 2 , the registration unit 310 may register an artwork from the user terminal 100 , assign a unique code, and map information and images of the artwork included in the artwork registration event to register. At this time, the registration unit 310 may receive the artist's information, the type of work, the size of the work, the desired price, etc. from the user terminal 100. After a unique code such as a QR code is given, only the unique code is scanned or You can register as a leader. Here, when the user of the user terminal 100 is the owner, the registration unit 310 may further receive a purchase price, a purchase time, and the like.

The inspection unit 320 may store the inspection result data of inspecting the worn artwork when the artwork is received. In order for the deposit to be established, the depositor entrusts the storage of the goods, and the person in charge must consent to it. Here, the painting is damaged the moment it is removed to analyze the components of the paint drawn on the canvas. Accordingly, although various technologies such as radiation and X-ray exist, they exist only in national institutions or large enterprises because equipment is required, and individuals or small and medium-sized enterprises (SMEs) rarely provide them realistically.

Accordingly, in an embodiment of the present invention, the RGB value of the pixel unit of the image may be stored using an artificial intelligence algorithm. First, the RGB values of pixels, that is, nodes are arranged in a row, and a kernel can be used to find a pattern from the sorted numbers. Here, the RGB value expresses the color expressed in the original image as a hexadecimal number for each value of three types of light sources: red, green, and blue, where node values are arranged in a line to form an input layer. In the case of a black-and-white image, one channel forms an input layer, but in the case of a color image, each channel can be separated into each RGB to form an input layer, and the process of finding a pattern can be performed in a hidden layer. At this time, the kernel, which is a number grid, moves the nodes one after another and derives the convolution, which is the sum of the product of the number of the kernel and the node value. By repeating this process, a feature map with a reduced number of nodes can be created, and then feature values are derived by applying an activation function. It can prevent counterfeiting even if it is sold or rented. At this time, there are many types of artificial intelligence algorithms, but a convolutional neural network (CNN) can be used. This is because CNN is suitable for image processing with a network structure using a convolutional layer, and can classify images based on features in images by inputting image data.

At this time, if only the value of each pixel is stored, if the shooting environment or camera changes, or if the direction, shooting location, or angle changes, even the same work can be judged as a different work, so it is possible to learn the brushstroke data of the same artist. can This is similar to the principle of appraisal of handwriting. If RNN (recurrent neural network) is used for the same artist's brushstroke data, it reflects time-series changes, so even if the artist's brushstroke data is changed, it is not judged as different works. . At this time, brush strokes in painting are expressed as strokes, and when these strokes are converted into data, a stroke profile can be created. However, in order to create a stroke profile, it is necessary to retain data for various works, and even if image transformation such as rotation or size adjustment is used to expand the database, the fundamental problem is still not solved. Therefore, it is possible to increase the accuracy of the stroke profile by creating a new shape stroke while preserving the texture and characteristics of the existing stroke.

A stroke has two curve directions based on the center, up and down, and to bend in a desired direction, the start point (srtPoint) and end point (endPoint) of the stroke must be known, so a bounding box including the entire stroke is created. Then, after dividing along the horizontal axis, a box at the beginning of brush strokes and a box at the end of the brush stroke may be created. When brushing, the histogram value can be higher than the beginning of the brush, as it is completed by pressing and releasing the brush. In addition, in order to set the curve weight to be as similar as possible to that drawn by a person, it can be set within an anatomically possible range. In this case, the inner angle of the arc is the curve weight, and the center point of the stroke is the starting point for warping. The target points are the points that meet the arc when a straight line is drawn from the center of the arc in the direction of the starting point. When curve weighting is given in this way, various types of databases can be obtained, a training data set for training can be obtained abundantly, and as a result, it is possible to output with high accuracy even for a query to be classified into a modeled profile.

The storage unit 330 may map and store the unique code and the identification code in the IoT storage 500 in which the artwork is stored. In this case, the storage unit 330 may store the identification code and its coordinates for each area or for each partitioned space. At this time, the reason for storing the coordinates is to manage the log for each art piece by identifying the temperature and humidity that change for each location in the IoT storage 500 below. This is because it is heating and cooling or central control. Of course, it may be excluded if the air conditioning system is individually installed. In this case, an IoT sensor (not shown) may be installed for each node in the form of a mesh for each coordinate, and the IoT sensor also stores each coordinate value, so that it may be linked with an identification code. In this way, when the location where the artwork is received is managed for each coordinate using the identification code, the environment of the location can be stored as a log, so that the accuracy of the log record of the artwork can be improved.

The sharing unit 340 may stream monitoring data transmitted in real time from the IoT storage 500 to be uploaded. In this case, the IoT storage 500 should include at least one detection sensor, and control air conditioning, ventilation, lighting, etc. using the value sensed by the detection sensor. In addition, it is necessary to detect a case in which a representative mold among biological degradation factors floats in the air. In addition, since the closed storage is hardly dry, the release of moisture can continue, and since Ca or Mg ions or their hydroxides are released as well as the release of moisture, high alkalinity is exerted, which adversely affects the preservation environment.

Accordingly, when performing basic temperature and humidity control, the IoT storage 500 minimizes the difference between inside and outside air in case the door of the storage is frequently opened and closed, and prevents cross contamination. By installing an airtight gasket on the door frame, it can be configured so that heat, moisture, and pollutants from the outside can enter the inside in normal times. However, in consideration of the energy cost according to the 24/7 operation, in an embodiment of the present invention, energy can be saved by recovering exhaust heat. As an example of a method of recovering exhaust heat from a heat pump during cooling, the high-temperature and high-pressure refrigerant gas generated from the compressor moves to the air conditioner part through the oil separator and valve in turn, and the exhaust heat recovery coil installed in the exhaust fan unit and the air conditioner The refrigerant is condensed in the reheat coil and outdoor unit coil, and the refrigerant that has passed through the receiver expands through the expansion valve before entering the cooling coil and evaporates in the cooling coil. The refrigerant is sucked into the compressor through the water separator and circulated. rough Conversely, during heating, it is the same from the heat pump to the air conditioner, but after that, it proceeds in the opposite direction to the case of cooling. The refrigerant is sucked back into the compressor in the order of evaporating from the exhaust heat recovery coil installed in the exhaust fan unit, so that the circulation can be continuously repeated. When the above-described method is used, energy can be saved by reusing exhaust heat while preventing cross-contamination.

The interlocking unit 350 registers an identification code corresponding to at least one location of the IoT storage 500, creates a communication channel to interwork with the IoT storage 500, temperature, humidity, A database can be built for adjustment parameters including illuminance and light wavelength. At this time, the IoT communication protocol is being developed in various ways by the IETF standardization organization. In particular, a low-power loss network composed of resource-constrained devices is assumed as a local IoT environment, and a technology for providing Internet connectivity to resource-constrained devices (Constrained Node) is provided. is developing At this time, the IETF recognizes the Low Power and Lossy Network (LLN) composed of resource-constrained nodes as the Internet of Things access network environment and is focusing on developing standard technologies for access networks related to the Internet of Things. It means that the focus is on access networking technology rather than core networking technology.

Accordingly, the interworking unit 350 of the present invention may use a networking method for constructing a non-infrastructure-less based IoT network in an access network environment composed of an infrastructure-based network. Here, the interworking unit 350 builds core networking using a Self-Organization Networking (SON) technique that configures a network in which nodes participating in the network can efficiently transmit data by themselves, and uses this to build a mesh form. to form a communication channel with the nodes arranged as At this time, a control node is set among the plurality of nodes, and the set control node performs the role of a group leader with nodes around it as group members. At this time, the two domains are divided into a physical domain configured based on the information on which the actual node is located and a control domain composed of a control node. The control domain is an overlay network type domain used to exchange information necessary for network configuration. In particular, since the control node serves as a representative node representing the group to which it belongs, it delivers the node and control message belonging to the group to the control node instead. In addition, the gateway that connects the infrastructure-based network and the Internet is designated as the node serving as the SON coordinator that connects the control node and the node with the highest authority of the non-infrastructure-based IoT network. Therefore, the SON coordinator collects and manages information of all nodes existing in the non-infrastructure based IoT network, and makes a final decision on link creation when configuring the IoT network. In addition, it is set so that it can simultaneously perform the role of performing the Neighbor Discovery (ND) function, which is a neighbor node discovery process in a non-infrastructure-based IoT network.

In this way, when a representative is elected and becomes a control node, it is necessary to group by searching for neighboring nodes. At this time, when performing ND, a 6LoWPAN Router (6LR) node is selected among the outnodes, and the Duplicate Address Request/Duplicate Address Confirmation (DAR/DAC) message is exchanged with 6LoWPAN Border Routers (6LBR) through the 6LR node to perform the ND process. ND technology can be used. Furthermore, instead of transmitting the DAR message to the gateway performed by 6LBR, it may be configured to reduce the number of control messages generated in the ND process in the network by exchanging DAR/DAC messages to the control node that manages itself. When the network is formed in this way, a path setting and discovery process is required for data transfer between nodes. In this case, a layer-based path setting and discovery method can be used. The hierarchical area is the area managed by the control node, and the control message required for path search is delivered only within the control domain composed of the control node. Therefore, each node in the physical domain can set a path in the physical domain through the path searched by the control node and data can be transmitted. Of course, it will be apparent that, in addition to the above-described method, various methods for constructing an infrastructure using the IoT node or sensor of the IoT storage 500 are available.

The log unit 360 may map information and images of artworks registered in the register, inspection result data, and monitoring data of the IoT storage 500 to a unique code of the artwork and manage it as a history log. In this case, the monitoring data may include at least one or a combination of at least one of text, an image, and a moving picture, but is not limited to the listed ones and is not excluded for reasons not listed. At this time, since the log can be used as important evidence to prove nepotism when a dispute occurs later, the block chain can be used to exclude the possibility of manipulation. Here, the blockchain technology is a data forgery prevention technology based on distributed computing technology. The transaction containing the user's request is stored in the unit of data called a block, and it is replicated and stored in the form of a chain in the nodes constituting the distributed network. Blockchain technology uses a hash function that maps data of arbitrary length to data of a fixed length. features that cannot be done. Integrity is guaranteed through the characteristics of the hash function, and an asymmetric key encryption method using a public key private key is used to ensure confidentiality. Through this, blockchain technology can prevent forgery and falsification of data by verifying transactions and comparing hash values.

The control unit 370 transmits the control command signal to the IoT storage 500 so that the control parameter previously mapped to the unique code of the artwork is reflected in the area corresponding to the identification code of the IoT in which the artwork is stored, and to the control command signal PID (Proportional-Integral-Differential) control may be performed by collecting data as a result of driving the corresponding IoT storage 500 and receiving feedback. At this time, the air conditioning system should select each optimal set value for indoor load fluctuation and energy saving according to the change of the system control variable and have a command following characteristic. For example, if it is assumed that the control system that compensates the set value of the indoor supply temperature and return air according to the outdoor air temperature is controlled in consideration of the environmental variables, the outdoor air compensation control system has mathematical model error and uncertainty, and the uncertainty is Because it changes relatively slowly, a control algorithm with excellent control performance is required for changes in the external environment. Adaptive control can improve the control performance of a given control system by appropriately changing the structure or parameters of the controller when mathematical model errors and uncertainties exist. In PID control, the control output is returned to the input so that the output follows the set value without being affected by disturbance. However, when the external environment change is large, the characteristics of the control target change and the control performance deteriorates. Accordingly, when the adaptive control function is further added to the PID control, the parameter can be appropriately converted by measuring and using the control error according to the change in the outdoor air. By applying the adaptive PID controller that can improve command-following performance even when external air and indoor load change due to the influence of uncertainty and disturbance in the heating system, parameter hunting can be reduced and safety can be increased. Of course, it will be obvious that it is applicable not only to temperature, but also to humidity, pollutant removal, illuminance control, and the like.

There are many elements that make up a painting. Painting consists of physical features that can be directly extracted from painting, such as color and texture, and high-level artistic features such as composition, harmony and symmetry created by combining physical features. Painters express their emotions using physical characteristics and artistic characteristics that are a combination of them. If these characteristics are databased and each art object is tagged, which works will be recommended to the customer and what kind of work will be presented in the customer's office. Supply chain management is also possible by understanding supply and demand, such as whether a painting is suitable, what kind of art works in autumn or winter, and what characteristics an artist's work is needed. Therefore, in one embodiment of the present invention, not only tagging a tag indicating a characteristic, but also tagging a tag based on emotion so that a search is possible even if a non-expert incorrectly inputs a search word, and for this, an Arousal-Valence emotion model is used. can

To this end, the recommendation unit 380 defines characteristics that can be representative characteristics in conversation, uses these characteristics to model a model for predicting emotions in conversation through machine learning, and then uses the user's emotional words After entering as a query and extracting a tag using the predicted Arousal-Valence value, artworks with the corresponding tag can be listed as a recommendation list. In detail, in order to map conversation and tag, conversation and tag should be placed on one emotional coordinate system. , for example, the characteristics may be a technique through a combination of colors, a composition that is a set of lines, symmetry, and the like. The next step is regression, where a tag data set used for conversation analysis is collected, and regression analysis can be performed using the collected data set and feature values extracted from feature extraction. In this case, the tag and the feature have a correlation, and when an emotion tag is input, a matching picture can be selected. In this case, the emotional tag may use an already established corpus such as an emotional adjective, and may be, for example, elegant, noble, subtle, gentle, modern, dynamic, colorful, etc., but is not limited thereto.
