Description

SYSTEM AND METHOD FOR MEDIATING CONSTRUCTION COMPONENTS THROUGH NETWORK {SYSTEM AND METHOD FOR PROVIDING INTERMEDIATION SERVICE OF CONSTRUCTION ELEMENT USING NETWORK}

The present invention relates to a building construction brokerage system and a service method for easily purchasing a building construction such as trees and efficiently using it in an electronic commerce system through a network.

By the early 1990s, only a few people knew how to use a computer, and among those who knew how to use a computer, only a few could use the Internet as a means of communication. The age has come. As described above, one of the biggest reasons why the use of the Internet can be popularized is the practical use of the World Wide Web (WWW).

Recently, various services such as e-commerce, e-news, cyber stock trading, and electronic mail (e-mail) have been provided based on the internet using the web. Internet service is emerging as the most important business as it is easily accessible through the Internet.

In general, the Internet refers to a plurality of unit networks divided by an Internet Protocol (hereinafter, referred to as IP) address and a plurality of hosts having individual IP addresses provided in each unit network. Based on the Transmission Control Protocol / Internet Protocol (hereinafter referred to as TCP / IP), a local area network (LAN) or a public switched telephone network (PSTN) It is a data communication network capable of performing data communication. In this case, the host means that a computer or a computer equipped with a communication modem and a telephone are connected, and mutual communication is possible only with a unique IP address assigned to each host.

1 is a block diagram of a conventional network for connecting to the Internet. Referring to FIG. 1, a conventional network for accessing the Internet includes an Internet terminal device 10 provided with a command input by a user in order to obtain desired information, and a command and an IP address of the user from the Internet terminal device 10. A wired network 20 for receiving a connection with another terminal device and receiving a command and an IP address from the wired network 20 and converting the data into a type of data used in the Internet (Gateway: 30). And an internet 40 for arranging a connection between different networks to perform a command transmitted from the gateway 30, and a web server receiving web commands from the internet 40 and providing web information. server: 50, an Internet service provider (ISP) for receiving a command from the Internet 40, and connecting to another network; An intranet 70 connected to the Internet 40 through an Internet service provider 60 and a database 80 owned by the intranet 70 are included.

Referring to FIG. 1, the operation of the network is executed. First, the Internet terminal device 10 executes an Internet program, attempts to connect to a network to which the IP address is desired, and has its own IP address. The connection attempt is made by connecting to the Internet 30 through a wired network 20 to which the Internet terminal device 10 is connected, and then to the Internet 40 using a protocol such as TCP / IP. Once the connection is established, the Internet 40 informs the Internet terminal device 10 of the information of the place where the user wants to connect, and then performs data transmission from each other. If the desired information is in a database of a specific network connected to the Internet 40, the information of the database 80 connected to the intranet through the Internet service provider 60 connected to the Internet 40 and connected to the intranet You will be connected to

Through the network of the above structure, the user is trying to search for information through the Internet called "sea of information", extract the desired information and make it as your own information.

However, there is a problem in that the mobility of the terminal device cannot be secured in the network for the Internet connection configured as described above. However, thanks to the recent rapid development of the telecommunications and electronics industry, various mobile hosts combined with portable computers and mobile terminals use the existing IP address and provide Internet access service while moving away from their fixed network location. Mobile Internet technology has been proposed.

2 is a block diagram of a conventional mobile Internet service system using a wireless network. Referring to FIG. 2, a conventional mobile Internet service system is equipped with an external command input device such as a keypad or a touch screen to receive a command, and converts and transmits a command to an RF (Radio Frequency) signal suitable for data service. The Internet terminal apparatus 100, the base station apparatus 200 which receives the RF signal transmitted from the wireless internet terminal apparatus 100 and demodulates it into a command, and the ID of the wireless internet terminal apparatus which transmitted the command ( The wireless network 210 outputs using the protocol for the Internet service together with the IDentity number, and receives the protocol signal for the Internet service from the wireless network 210 and converts it into a protocol such as TCP / IP suitable for Internet access. Gateway 220 for outputting the data, and a connection with another network for an operation corresponding to a command from the gateway 220. Internet 230 to enable connection, a web server 240 that receives instructions from the Internet 230 to provide web information, and a mobile Internet that receives instructions from the Internet 230 and connects to another network. A service provider 250, an intranet 260 corresponding to an enterprise-dedicated network connected to the Internet 230 through the mobile Internet service provider 250, and information stored in the intranet 260 itself. It consists of a database (270).

In the above, in order to receive the Internet information from the wireless Internet terminal device, there must be an intermediate medium that is connected to the gateway. This is because the data and protocols used in the wireless communication system and the data and protocols used on the Internet are different from each other, and thus heterogeneous data must be converted. However, the gateway may generally be included in the concept of a wireless network.

The operation of the mobile Internet service system having the above structure is as follows. When a user inputs a command through an external command input device such as a keypad or a touch screen, the input command is in a form suitable for a protocol between the wireless network 210 and the gateway 220 in the wireless Internet terminal device 100. Is converted to a command. The converted command is converted into an RF signal that can be transmitted to a wireless channel through spreading or modulation, and then transmitted to the base station apparatus 200. The base station apparatus 200 receives and demodulates an RF signal transmitted from the wireless internet terminal apparatus 100 and transmits the demodulated signal to the wireless network 210. Subsequently, in the wireless network 210, the gateway 220 converts a protocol language for Internet service in the wireless network, for example, a handheld device markup language (HDML), a wireless markup language (WML), or a mobility hyper text markup language (mHTML). ) The gateway 220 receiving the input converts the command input by the user into a TCP / IP form used in the Internet, and generates an Internet protocol address used in the Internet using the ID number of the wireless Internet terminal device 100. Access to the Internet 230. Subsequently, when a user inputs a command to obtain desired information, the user accesses the web server 240 using HTML, which is a protocol language supporting the web service on the Internet 230, and the user accesses information on another network. In the case of inputting a command for this, the Internet 230 accesses the mobile Internet service provider 250 using TCP / IP to obtain information stored in the database 270 connected thereto.

On the contrary, information transmission from the Internet 230 to the wireless Internet terminal device 100 is performed in the reverse order of the above-described method. First, the Internet 230 obtains information from the web server 240 or the intranet 260 and then transmits the information to the gateway 220. The gateway 220 receiving the information from the Internet 230 uses the HDML, mHTML, or WML protocol as the ID number of the wireless Internet terminal device 100 corresponding to the Internet protocol address. Output the above information. The wireless network 210 transmits information to the wireless Internet terminal device 100 through the base station apparatus 200 in the same manner as described above.

In recent years, e-commerce using the Internet is rapidly spreading, and this service has radically changed the conventional commerce system in which a customer visits a store and selects a product in order to purchase a product. You can buy what you want at home. In particular, various trading services such as securities, shopping, and the like are being activated using the Internet. Such services can be provided through wireless Internet terminal devices as well as wired Internet terminal devices, so that users can receive services without being restricted in mobility. It became possible.

However, until now, trees and construction materials, such as wood, rebar and cement, have been limited to specific routes to secure them. There was something difficult to achieve. In addition, in the case of trees, the brokerage service itself was difficult because the purchaser had to look directly at the tree he wanted to purchase and grasp the age, size, and material.

In addition to the above, there is no communication between the side of discharging surplus materials that are no longer useful at the construction site and the side of other construction projects using such surplus materials, so that one side of the building components is discarded. On the other side, it was true that there were many economic losses in the national aspect, such as repurchasing the building business.

The present invention is to solve the above problems, by selecting a tree to customers who wish to purchase, and by placing the selected tree directly to the desired place through the simulation, building construction brokerage that can more efficiently trade trees The purpose is to provide a system and a service method.

In addition, the present invention prevents environmental pollution by building components, and contributes to the national economy by immediately connecting not only wood, but also the discharge companies of construction surplus materials such as aggregates, rebars and companies that require such surplus materials. Its purpose is to provide an intermediary system and service method.

FIG. 6 is a flowchart illustrating a process of collecting tree-related data in a building construction brokerage service method according to an embodiment of the present invention. Referring to FIG. 6, in the building construction brokerage service method of the present invention, tree-related data may be collected from a producer who grows trees or trained majors (602). The collected data are then assessed by experts (604), which are structured by value classes or by the region in which the trees are grown and by the environment (606), which will be stored in a database of building construction brokerage systems.

The building construction brokerage service method provides a service to a producer or a buyer through a database constructed as described above, and a flowchart of a process of brokering a transaction according to a buyer's application is shown in FIG. 7. Referring to FIG. 7, the building construction brokerage service method of the present invention will identify a user connected to the building construction brokerage service server through a network (702), and search a database to extract data of the content requested by the user ( 704). At this time, since the service is for the purpose of trading the building components, it would be desirable to operate on a membership basis to ensure the stability of the transaction. The building construction brokerage service server transmits the building construction information extracted from the database to the user through the network (706), and the received user can construct the virtual structure or the virtual tree on the screen using the transmitted data. Upon request, the building component brokerage service server will run the simulation (708). The data is information on the building components such as trees, and specifically, it may contain the terrain, the photo of the trees, and the purchase related information where the trees are currently located. In addition, the simulation may be performed in two or three dimensions, and may be executed in an on-line state in which a user is connected to a server through a network, or may be executed in an off-line state by receiving necessary software.

Through virtual simulation, users can grow certain types of buildings or trees on large desired terrain, decorate their inner gardens, or change the interior of their homes. When the user executes the virtual simulation as described above or makes a purchase decision based on the transmitted data, the building component brokerage service server receives the user's purchase request (710) and sends the order to the corresponding producer (712). . Once the order has been sent, the producer may deliver the building component applied to the orderer according to the order, or the applicant may visit the producer and carry the building component directly.

In the above, the process of enabling the user to purchase the desired material by searching for the data provided from the building construction brokerage service server has been described. The buyer or the producer requests a transaction through the building construction brokerage service server of the present invention, and the contents of the application. According to the bidding can be auction.

Referring to FIG. 8, the building construction brokerage service method of the present invention will first receive an application for purchase of building construction from a buyer through a network (802). The reception method may be performed through a wireless communication terminal device or a landline telephone as well as reception through the Internet. The information received in this way is sent to a plurality of producers, respectively (804), it is possible to induce a transaction by sending the bid content to not only producers who are members as a member of the service of the present invention but also producers who are not members.

After the bidder's application is completed, the bidder proceeds (806), determines the best bidder, such as the lowest selling price or the producer located in the shortest distance to the desired area (808), and informs the applicant about the successful bidder. 810. If the purchase applicant is dissatisfied with the successful bidding information, the bidder is repeated to repeat the above process, and if the purchase applicant is satisfied with the successful bid contents and approves the transaction, the purchaser sends an order to the successful bidder (814) to close the transaction. do.

9 shows a flowchart of a method for brokering a transaction by bidding of a plurality of purchasers when a producer wants to sell building components in contrast to the above. 9 is a case where the transaction applicant is a producer and the bid applicant is a buyer, and the process thereof is the same as the process shown in FIG. 8.

In addition, the building construction brokerage service method of the present invention, if the user inputs a number such as the height of the tree, the circumference, and the height of the body desired by the user, the search system for searching for the most suitable tree for the content entered by the user and output it By providing it, it is possible for a user to simulate using more suitable trees.

FIG. 10 is a flowchart illustrating a case where an optimal search system is used in the building construction brokerage service method according to an exemplary embodiment of the present invention. Referring to FIG. 10, the building construction brokerage service method of the present invention first checks a user connected to a server through a network (1002), and receives detailed tree-related data that the user wants to search for (1004). In this case, the detailed tree-related data may include contents such as tree type, height, circumference, trunk height, or branch size. When the user inputs data corresponding to each part, the building composition The mediation service server will search for trees that best fit the user's input (1006) and send them to the user (1008). Therefore, after the user executes the simulation using the tree that best matches the input (1010), the user will apply for a purchase (1016) if the simulation result meets his / her needs. However, if the simulation results do not meet the needs of the user, the user may re-enter the detailed data, and the building construction brokerage service server may receive the detailed data from the user again and repeat the search and simulation process. As a result, the building construction brokerage service server searches for the tree best suited for the data input by the user and transmits the tree to the user, and performs the simulation of constructing the building construction on the virtual terrain using the tree. Then, if the user applies for the purchase of a particular tree based on the simulation result, the order will be sent to the producer who owns the tree (1018), thereby closing the transaction between the user and the producer.

Furthermore, in the case where a user who wishes to purchase a tree wants to purchase one or more kinds of trees for landscaping or environment construction in a certain area, the most suitable among producers having all of a plurality of species desired to purchase The efficiency of the transaction can be improved by selecting a user and informing the purchaser of the user.

That is, the purchaser has received all kinds of trees, desired delivery location, price, etc., and has all the trees corresponding to the above contents. Connect them together. If it is determined that the producer searched above is not suitable for the condition of the purchaser, the producer having the optimal condition is searched again and informed to the purchaser of the producers except for the producer. It is possible to select producers with

In the case of a large-scale construction, such a retrieval system may require the purchase of trees from the producers with the closest transport distance among the producers with all the varieties required for the construction. This is because the economic effect can be obtained. Therefore, it is preferable that the search system searches the producers having the closest transport distances among the producers having all the trees desired to be purchased as the highest priority. It will be apparent that such a search system is not limited to trees, but can be applied to all kinds of building constructions.

In the above description, a process of brokering a transaction of a building component through a method of a producer or a buyer or an auction between a producer and a buyer has been described, but a person skilled in the art having ordinary knowledge in the technical field of the present invention changes or It will be easy to correct.

In the construction industry using wood, aggregate, and reinforcing bars, not only the supply and demand of building components required to build the structure but also the processing of surplus materials generated during the demolition of existing buildings are very important. This is because a place for treating surplus materials such as aggregate and rebar generated or a method of treating the same is not easy. However, at construction sites to fill the ground, such as building bridges or dams, surplus materials generated after building demolition are useful as described above. In general, mutual contact between builders in generating and transporting surplus materials On the other hand, it is difficult to deal with unnecessary surplus materials on one side, while the other side cannot collect unnecessary surplus materials and incurs extra costs and often collects aggregates from nearby wild acids. Accordingly, it is true that there are many environmental damages and economic losses due to illegal dumping of surplus materials.
