EARTH INFORMATION SYSTEM AND AN APPLICATION METHOD FOR THE SYSTEM

[Technical Field]

The present invention relates to an earth information system for use in utilizing earth resources mutually.

[Background Art]

In various construction sites, and particularly large- scale construction sites such as a harbor and a tunnel, a very large amount of earth is generated or needed. For example, a large amount of earth is generated by cutting the mountain, in a case of tunnel and road construction site, and a large amount of earth is needed since the ground must be generated by filling forshore or sea with the earth in a case of the reclamation site. The construction which generates or needs the earth includes mostly works, in which the works correspond to public works such as road, bridge, antiflood afforestion, four direction river, dam, harbor, railway, tunnel, waterworks, sewer, filteration plant, residential land development, industrial land development, reclamation, irrigation canal, agricultural land arrangement, and construction works greater

than a certain scale such as apartment, commercial building, school, hospital, or SOC works of personal engineering works and golf course works. If a large amount of earth is generated during the construction works, the earth must be discarded using proper means, which results that it tends to waste a lot of manpower, cost and time in the course of discarding the earth. In contrast, since the earth must be provided at the proper time in conformity with the works plan in a case of the construction which needs the large amount of earth, more effort is needed to seek information and realize the transaction in order to purchase the earth. Though the earth can be purchased from the area where a large amount of earth is generated as described above, the earth must be delivered from the construction site separated at a long distance due to a lack of information, leading to an increase in the construction duration and unnecessary wastes of manpower and costs .

Fig. 1 shows a simplified diagram showing idea of sharing the earth resource in construction site according to the prior art. In a site A, works are conducted to make higher the ground by accumulating the earth on an original ground, which such works is referred to as banking or filling. In the banking site, a very large amount of earth is necessarily needed. The amount of earth needed to complete the works in

the site A is expressed in (1) . The amount of earth generated in the site A (and thereby can be used in the banking works of the site A) is (2) , which is a very little amount compared to the (1) as shown, and therefore the amount of necessary earth must be purchased in order to conduct the works normally.

In a site B, works are conducted to make lower the ground by cutting the earth, which is referred to sanding or cutting. The sanding site generates a very large amount of earth in contrast to the banking site. In the site B, the amount of earth generated until completing the construction is expressed by (3) . The amount of earth which is available and can be treated again in the site B is (4) , which is a very much amount as compared with (3) and therefore remaining earth must be discarded using a proper means in order to conduct the works properly.

In the site A, since it is difficult to find other construction site where the amount of earth is generated by a necessary supply amount at a time, as well as it takes economically much risk to deliver the earth from the construction site separated at a long distance from the construction site A, a main body of the construction site A must purchase and fill the earth from construction sites in near surrounding area. In contrast, the earth generated in the sanding site can be simply discarded by throwing away

somewhere in the neighborhood in a case of the construction site B. However, there can be a remaining amount of earth if much more earth is generated than the amount which can be treated, and therefore the remaining amount of earth must be discarded at a further distance or sold to the construction sites where needs the earth in the near surrounding area.

During the procedures, though complex procedures do not need to be performed if the remaining earth of the construction site B is used in the construction site A, it is often common practice to sold and discard the earth in the complex procedures as mentioned above since the construction sites A and B can not timely share the information of generated/necessary amount of the earth with each other.

[Best Mode]

Hereinafter, the embodiments of the present invention will be described in detail with reference to accompanying

drawings .

Fig. 2 is a drawing showing a concept of sharing earth resources information in construction sites according to the present invention. In contrast to Fig. 1, since the construction sites A and B can share the information with each other according to the present invention, the necessary amount of earth in the construction site A can be supplied from the site B whereas remaining earth in the construction site B can be easily treated by sending it to the construction site A without needing any discarding process or method. In other words, if each of the construction sites shares the information of its own earth resources generated/needed with each other as in the construction sites A and B, it is possible to resolve problems related to supply/treatment of the earth in connection with other construction conforming to its own condition in each of the construction sites.

Fig. 3 is a system diagram showing the earth information system according to the present invention. The earth information system according to the present invention includes a database 100 which stores a variety of information, a client 200 which inputs a generated or necessary condition of the earth resource, a transaction information of the earth resource, and a search request of the earth information to the earth database 110, or outputs information inquiry and search

results related to the earth resource, a central server 300 which connects the database 100 with the client 200 to transmit the information inputted from the client 200 to the database 100 or process and output a variety of information to the client 200 in response to the requests inputted from the client 200, and a transaction system 400 which processes the transaction of the earth resources by using the transaction information including a user authentication information and a transaction request information for the earth resource. Further, the earth information system preferably includes an authentication system 500 to authenticate a user, in order to process the transaction or limit the right of inquiry/input/statistics .

The database 100 is divided into parts including an earth database 110 which stores the earth information including generation and necessity of the earth resources, geographical database 120 which stores map information including geographical locations, a statistics database 130 which stores statistics information computed using the earth information. The earth database 110 includes items for storing a variety of information related to the earth resource, in which the items includes generated or necessary amount of the earth, generated or necessary location of the earth, a kind of the earth, a usage of earth, a construction location, a construction name,

a kind of construction, a main body of construction, a construction condition, a construction plan, a date, a transaction condition, a transaction plan, a delivery distance, a delivery cost, a delivery unit cost and so on. The central server 300 may process the information to enable displaying the location-related information such as the construction location from the information stored in the earth database 110 on the map in connection with the geographical information of the geographical database 120. Fig. 4 is a diagram showing one operational example of the earth information system according to the present invention. As shown, each main body of the constructions (i.e., an ordering agency in a case of public construction, and an orderer and a building company in a case of private construction) can input detailed contents in accordance with various items included in the earth database 110 through the client 200. Fig. 4 shows the earth information related to banking, in which a kind of earth (A) such as soil and sand, ripping rock, blasting rock, and a kind of detailed earth (B) may be defined, and a usage (D) and a necessary amount of earth (D) may be also defined. Of course, the item of the necessary amount of earth can be substituted with the generated amount of earth in a case of the earth information related to sanding. Further, banking generation location (in a

case of banking site) or the sanding generation location (in a case of sanding site) (G) is defined on the map, which the item (G) can associate the information of the earth database 110 with the information of the geographical database 120. Fig. 5 is a diagram showing one example of indicating the construction site in the earth information system according to the present invention. According to the earth information system, it can allow the user to easily find near construction site by dividing into the banking site, sanding site, and a complex site to display them on the map. Of course, if the user inputs the geographical information such as an administrative district when he inputs the construction site, he can easily confirm the construction site by associating the information with the map image to display present construction site on the map image of the geographical database 120. In other words, the earth information system of the present invention can allow the user to recognize the present status of the earth resource visually and intuitively by displaying the earth information on the map using Geographic Information System (GIS) such as the geographical database 120. Further, the user can know how much benefit will be generated when future transaction is occurred through the transaction system 400 by inputting the delivery distance (H) , the delivery unit cost (I), and the delivery costs (J), and such information is

immediately summed up as statistics and status .

Further, according to the earth information system of the present invention, it is possible to input the construction plan (E) , such as of using the earth generated in the banking site itself and purchasing the earth from other site, in a case of banking as shown in Fig. 4. Such information is input into the construction plan (E) , and the corresponding contents can be separately stored as a transaction plan when the transaction is occurred. That is, Fig. 4 shows one operational example of the earth information system according to the present invention, in which the information includes one portion of items such as the generated and necessary amount of the earth, the delivery unit cost and the like, but may include more item as necessary. The central server 300 is connected with the database 100, the client 200 and the transaction system 400 as mentioned above, to output the map image on the client and display the generated and necessary amount and location of the earth on the map image by matching the map information stored in the geographical database 120 with the earth information stored in the earth database 110, process the transaction in association with the transaction system 400 if the transaction is requested, search the earth information stored in the earth database 110 to output the search result to the client 200 if

the search is requested, and process the statistics operation. If the statistics information is requested from the client 200, the central server 300 computes the statistics information including the present status using the earth information stored in the earth database 110 to store it in the statistics database 130 and output it to the client 200.

Fig. 6 shows an example of outputting the statistics information. The number of construction cases processed by the ordering agency, the amount of sandy soil or bank soil generated for each construction and so on are displayed manifestly, as shown in Fig. 6(A), and the user is allowed to access the statistics information of desired type using various detailed conditions by finding out the earth statistics information within a certain diameter on the map, as shown in Fig. 6(B) . Though anyone can search such statistics information, it is more preferable to search it only at a credible public office, e.g., the ministry of construction and transportation. Therefore, before requesting and outputting the statistics, it is preferable to authenticate the user having a right to manage the statistics through the authentication system 500.

By processing, searching and outputting the statistics information, the ministry of construction and transportation can conduct the investigation and adjustment for unmanaged

business using such statistics information when the adjustment is requested due to a design change. Further, it is possible to check the status and statistics of the earth resource manifestly and thereby to search/investigate/control whether plans to take-in or take-out the earth resource for the new design and the design change are proper or not.

Table 1 discloses the earth information system of the present invention by analyzing for each function. That is, the input system inputting and managing the earth information includes the client 200, the earth database 110, the geographical database 120 and the central server 300. The search system searching the earth information includes the client 200, the earth database 110, the geographical database 120 and the central server 300. The status statistics system aggregating the status and statistics includes the client 200, the earth database 110, the geographical database 120, the statistics database 130 and the central server 300. At this time, it is preferable to divide the users into the user capable of performing only search (entire nation) , the user capable of inputting and managing the earth information (a main body of the construction such as ordering agency and building company) , and the user capable of adding up status and statistics of the earth information (governmental organization such as the ministry of construction and

transportation) , by passing through the user authentication using the authentication system 500 as mentioned above. [Table 1]

Of course, the earth information system according to the present invention does not need a separate program upon implementing the search system/input system/status statistics system, since it uses a web-based environment in which the client 200 is connected with the central server 300 through a wired/wireless network such as an Internet as shown in Fig. 3. Therefore, when classifying the users into the user capable of performing only search (entire nation) , the user capable of inputting and managing the earth information (a main body of the construction such as ordering agency and building company) , and the user capable of aggregating status and statistics of the earth information (governmental organization such as the ministry of construction and transportation) , the users may be

classified by authenticating the user through the authentication system 500 to divide the right or by causing each of the systems (search system/input system/status statistics system) to operate independent site while sharing all of the database 100, the central server 300 and the like.

Fig. 7 is a diagram showing information management process using the earth information system according to the present invention. As shown, actual construction process procedures are matched one-to-one with system registration procedures to maximize the convenience of the user, as well as systemically control the earth resource information in a design stage, so that future resource generation in other sites may be expected to be utilized for the design. In addition, it is possible to assure transparency of the earth resource information by historically controlling such all changed matters and thereby to prevent irregularities in the construction sites due to a random design change.

The transaction system 400 according to the present invention is used for mutual communication between the sanding/banking sites to allow the information to be shared with each other for utilizing the earth resource and allow the actual transaction to be realized. The transaction system 400 can be responsible for reducing physical businesses by implementing requests, investigation and acknowledgment

procedures for the transaction between the users in a computerized manner. Further, the transaction information of the transaction system 400 is transmitted to the database 100 through the central server 300 so that the database 100 may be updated in a real time, which results that the user can achieve correct information of high reliability in a real time.

Fig. 8 is an operational step diagram of an electronic sale publishing system included in the transaction system 400 of the present invention. The electronic sale publishing system 410 is used in a case of selling the earth resource of the construction site to private operators, not exchanging the earth resource between the sites. As shown in Fig. 8, if the main body of the construction who is to sell the earth resource makes a public notice of sale be published in the electronic sale publishing system 410 by recording a kind of earth, amount of sale, tender condition, the public notice of sale is noticed to allow anyone to search the corresponding electronic public notice of sale. Therefore, aggregate dealers can participate in the tender, the main body of the construction completes the tender, and subsequently the tender result is inputted and updated to the electronic sale publishing system 410, which results that all sale procedures can be electronically performed.

[industrial Applicability]

The tender sales are conducted by publishing such earth resource in the daily paper, newspaper and the like according to the prior art, whereas the public notice of sale and tender sales can be electronically conducted according to the present invention. Therefore, announcement costs can be saved, as well as accessibility to the information is considerably increased. According to the present invention, integrated management is becoming possible in association with the aggregate dealers by providing the aggregate recycling system, i.e., the construction wastes information. Further, the main body of the construction can understand the aggregate dealers manifestly by displaying the aggregate dealers on the map image in connection with the geographical database 120. Those skilled in the art will appreciate that the conceptions and specific embodiments disclosed in the foregoing description may be readily utilized as a basis for modifying or designing other embodiments for carrying out the same purposes of the present invention. Those skilled in the art will also appreciate that such equivalent embodiments do not depart from the spirit and scope of the invention as set forth in the appended claims .
