JP6342882B2 - Buried pipe information management device - Google Patents

Description

  The present invention relates to a buried pipe information management device that provides information related to a buried pipe of gas.

  Conventionally, in B-to-B (Business-to-Business) transactions, a form for ordering is displayed on a site on the Internet, and individual delivery conditions (unit price, delivery date, delivery method, etc.) previously traded for each member are taken into account. A system in which product information is displayed is disclosed (for example, Patent Document 1).

  In addition, as for the underground pipe for city gas, there is a case where a BtoB transaction is performed when a new installation is required. A user such as a construction company or a real estate company requests a gas company for a construction estimate for a new buried pipe. In order to derive such a construction estimate, highly confidential information is used.

  For this reason, due to security problems, an estimate derivation system for deriving a construction estimate for a new buried pipe has been operated separately from an existing answering system that answers the existing situation of the buried pipe. The user makes a reply request for the installation status of the existing buried pipe via the Internet using the installation response system. When it was determined that there was no existing buried pipe nearby and that a new construction work was required for the buried pipe, a separate estimate request was made to the person in charge of the gas company.

  The conduit business for burying these buried pipes and the gas retail business are carried out by the same gas company. Therefore, when the person in charge of the gas company receives a request for an estimate or when it is decided that an estimate will be made in the first place, the information entered at the time of confirming the placement status of the buried pipe that has been performed in advance will be used. It was possible to confirm.

JP 2002-31647 A

  By the way, it is determined that the gas retail business will be liberalized in the future, and a plurality of retailers are scheduled to sell gas. The arrangement answering system and the estimate deriving system are managed by a conduit operator different from the retailer. That is, the conduit business and the retail business that were operated by the same gas company before the liberalization will be operated by different companies after the liberalization.

  As a result, the person in charge of the retailer who received the request for quotation cannot obtain the information entered when confirming the status of the buried pipe, which would have been accumulated in the conduit company that became a separate company. It is expected that. In this case, if there is an error in the information transmitted at the time of requesting an estimate, an accurate estimate result cannot be obtained, and another estimate process is required. If it does so, while the work efficiency of a person in charge will fall, the estimate reply to a user will also become late, and a user's convenience will fall.

  An object of the present invention is to provide a buried pipe information management apparatus that can improve workability and convenience for a retailer with respect to construction estimation of a buried pipe for gas.

In order to solve the above-described problems, the buried pipe information management device of the present invention provides an arrangement response system for answering the arrangement status of existing gas buried pipes via an input screen generated by the arrangement reply system. The communication unit that communicates to the estimate derivation system for deriving the estimate of the construction to newly install the gas buried pipe, and accepts the input of user information and address information for each account, Sending the address information to the interface unit to be associated with the system and the response system for requesting the response result of the service system, and if the response result is a content that requires construction, the estimate derivation system by sending the address information, you have line an estimate request to estimate the results of the estimates derived system, the answer results, the construction work that established the buried pipe because there is an existing buried pipe not If the content is, and a request unit configured to cancel the estimation request, the interface unit, the user information, address information, answer address information is obtained is transmitted result, and, on the estimated result, accessible account It is characterized by.

  The interface unit generates a management screen that can be accessed for each account, and / or one or both of a response result and an estimation result for one or a plurality of address information input in the account that can access the management screen, or a response A link to one or both of the result and the estimation result may be displayed on the management screen.

  In addition to user information and address information, the interface unit accepts input of pull-in information indicating the position where the extraction pipe is drawn in the site, and the request part includes the position of the existing buried pipe in the answer result and the pull-in information. Based on this, it may be determined whether or not the construction for newly installing the buried pipe is unnecessary.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating the understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  The pipes are buried underground to supply city gas. The gas main pipe (main branch pipe) buried along the road under the road, etc., and the outlet for branching from the gas main pipe and drawing it into the site It is classified as a pipe (supply pipe). When building a building that uses city gas, a construction company or a real estate company (hereinafter referred to as a user) can use existing underground pipes (gas mains, take-outs) that can be used on or near the site such as the planned construction site. If there is no pipe, the construction cost for the construction of the buried pipe may be borne. Therefore, the user confirms the arrangement status of the existing buried pipe in the site and the vicinity thereof, and requests the construction estimate when the new buried pipe is required.

  FIG. 1 is an explanatory diagram for explaining a relationship of a business company related to a gas burying pipe. Until now, gas companies have operated both gas pipeline and gas retail businesses. As shown in Fig. 1, the gas pipeline and gas retail businesses will be separated in the future. Has been liberalized and it is planned that a plurality of retailers 10 will enter.

  When the user 20 needs to confirm the existing buried pipe arrangement status or estimate the construction of the new buried pipe, the user 20 uses a computer, for example, through the communication network N such as the Internet, and the conduit operator 30 and the retailer as appropriate. The request is made through the system (apparatus) of the business operator 10.

  Hereinafter, the buried pipe information management apparatus capable of improving the workability of the retailer 10 and the convenience of the user 20 will be described in detail with respect to the construction estimate of such a buried pipe.

  FIG. 2 is an explanatory diagram for explaining the configuration of the buried pipe information management device 100. The buried pipe information management apparatus 100 is managed by the retailer 10 and includes a communication unit 110, a storage unit 112, and a management control unit 114 as shown in FIG.

  The communication unit 110 communicates with the arrangement response system 32 and the estimate derivation system 34 managed by the conduit operator 30 via the communication network N. The arrangement response system 32 receives the address information of the site and answers the arrangement status of the existing buried pipes in the site and the vicinity thereof. The estimate deriving system 34 receives site address information and derives and returns a work estimate for newly installing a buried pipe up to the site.

  In order to derive such a construction estimate, highly confidential information is used. Therefore, the estimation derivation system 34 is operated separately from the arrangement answering system 32 due to security problems. The arrangement answering system 32 is disclosed via the communication network N, and the arrangement status of the buried pipe is answered to the buried pipe information management apparatus 100 via the communication network N by an automatic response.

  In the estimate derivation system 34, reception of address information and the like is automatically performed via the communication network N. Thereafter, in the functional unit disconnected from the communication network N, address information is registered by an operator's operation. And a construction estimate is derived. The estimation result of the construction estimate is transmitted to the buried pipe information management apparatus 100 via the communication network N by the operation of the operator.

  As described above, the arrangement answering system 32 is released from the estimate derivation system 34 via the communication network N, and has a function of providing a unique input screen to the user 20. . Therefore, the user 20 accesses the input screen generated by the arrangement response system 32 without directly accessing the buried pipe information management device 100, inputs the address information of the site via the input screen, and automatically enters the response screen. It is also possible to check the answer result by response.

  On the other hand, in the buried pipe information management device 100, the communication unit 110 communicates with the arrangement response system 32 via the communication network N without using the input screen generated by the arrangement response system 32.

  The storage unit 112 includes a RAM, a flash memory, an HDD, and the like, and holds various information necessary for processing of each function unit described below. For example, the storage unit 112 holds, for each account, user information, site address information, an answer result from the arrangement answer system 32, an estimate result from the estimate derivation system 34, and the like.

  The management control unit 114 is a computer configured by a semiconductor integrated circuit including a central processing unit (CPU), a ROM storing programs, a RAM as a work area, and the like, and controls the communication unit 110, the storage unit 112, and the like. To do. Further, the management control unit 114 functions as the interface unit 120 and the request unit 122.

  The interface unit 120 generates various screens that can be accessed by the user 20 via the communication network N. Specifically, the source code of such various screens is dynamically generated and transmitted to the computer of the user 20 via the communication network N. The computer of the user 20 displays various screens based on the source code.

  The screen generated by the interface unit 120 includes, for example, an input screen for receiving input of user information, site address information, and the like, a site identification screen, a response result from the arrangement response system 32, a result of estimation from the estimate derivation system 34, and the like. This is the item detail screen to be displayed. The input screen, site identification screen, and project details screen will be described in detail later.

  In addition, the interface unit 120 stores user information, site address information, and the like input via the input screen in the storage unit 112 in association with each account. The user information includes, for example, identification information (ID), a password, a company name of the user 20, a department name, a name, and the like.

  When the address information of the site is input via the input screen generated by the interface unit 120, the request unit 122 transmits the address information, a part of the user information, etc. to the arrangement answering system 32, and arranges it. An answer request for requesting the answer result of the answer system 32 is made, address information, a part of user information, etc. are transmitted to the estimate derivation system 34, and an estimate request for requesting the estimate result of the estimate derivation system 34 is made.

  Next, a buried pipe information management method in which the buried pipe information management apparatus 100 communicates with and cooperates with the arrangement answer system 32 and the estimate derivation system 34 will be described with reference to a flowchart.

  FIG. 3 is a flowchart showing a schematic flow of processing of the buried pipe information management method. Here, a description will be given of a process in which the user 20 has already created an account, has already logged in with the created account, and newly makes a reply request and an estimate request for the burial status of the buried pipe.

(Quotation request processing S214)
The request unit 122 executes an estimate request to the estimate derivation system 34 based on the answer result from the arrangement answer system 32. In the estimate request, the same address information and user information as those transmitted to the arrangement response system 32 are transmitted from the request unit 122 to the estimate deriving system 34.

  However, the request unit 122 can cancel the request for quotation when the response result from the arrangement answering system 32 is such that there is no need to construct a new buried pipe because there is an existing buried pipe. The determination as to whether or not to execute the quotation request will be described in detail later.

(Request reception process S216)
The estimate derivation system 34 receives the address information transmitted from the request unit 122 and accepts an answer request.

(Answer creation process S218)
Based on the address information transmitted from the request unit 122, the estimate deriving system 34 derives a construction estimate for newly installing a buried pipe up to the site, and obtains an estimate result for the estimate request.

  As described above, in the estimate deriving system 34, the functional unit for deriving the construction estimate is disconnected from the communication network N, and the registration of address information is performed by the operation of the operator, and the construction estimate is derived. .

(Answer transmission process S220)
When the estimate result is registered in the functional unit connected to the communication network N in the estimate derivation system 34 by the operation of the operator, the estimate derivation system 34 transmits the registered estimate result to the request unit 122.

(Estimate storage process S222)
The request unit 122 stores the estimation result from the estimation derivation system 34 in the storage unit 112 in association with the user 20 account.

(Result display process S224)
When there is an access request from the computer of the user 20, the interface unit 120 estimates the estimated result of the buried pipe installation and the answer to the buried pipe arrangement status stored in the storage unit 112 in association with the user 20 account. The result is generated as a management screen and displayed on the computer of the user 20.

  FIG. 4 is an explanatory diagram showing an example of the input screen 300. As shown in FIG. 4, for example, the input screen 300 accepts input of address information, scheduled gas use start date, and land purchase status (purchased, not purchased) of the site.

  Furthermore, the input screen 300 is provided with an input field (for example, a check box 302) for requesting an answer for only the arrangement status and selecting not to request a construction estimate. The check box 302 is not input (not checked) in the initial state, and the user 20 performs an operation input for checking the check box 302 when the construction estimate of the buried pipe is unnecessary.

  Then, when the input operation on the input screen 300 is completed and there is an operation input to the link arranged at the lower right of the screen, the interface unit 120 makes a transition to the site identification screen 400.

  FIG. 5 is an explanatory diagram showing an example of the site identification screen 400. As shown in FIG. 5, the site identification screen 400 shows the position indicated by the address information input on the input screen 300 and a map in the vicinity thereof. Then, when the user 20 performs an operation input on the site specifying screen 400, the site is marked so as to be identifiable (indicated by cross hatching in the drawing), and site information indicating a range on the site map is set. For example, the address information includes site information input on the site specifying screen 400 in addition to information input on the input screen 300.

  When the input operation on the site identification screen 400 is completed and there is an operation input to the link arranged at the lower right of the screen, the interface unit 120 makes a transition to the input confirmation screen. On the input confirmation screen, the user 20 can confirm that there are no errors in the input content on the input screen 300 or the site identification screen 400, and an operation input for confirming the input content is accepted. When the input content is confirmed, the input content is stored in the storage unit 112 in association with the account of the user 20.

  FIG. 6 is an explanatory diagram showing an example of the management screen 500. The management screen 500 is a top page displayed when, for example, account identification information or a password is entered on the login screen and a login operation is accepted. In this way, the interface unit 120 generates a management screen 500 that can be accessed for each account.

  As shown in FIG. 6, in the management screen 500, when the logged-in user 20 has made an arrangement status reply request or an estimate request in the past, the matter information regarding the arrangement status reply result or the estimate result Will be listed.

  Specifically, the buried pipe survey reception number, the reception date, the property information, and the retail business staff information are displayed for the response result and the estimation result of the past arrangement status. The buried pipe survey acceptance number is an identification number automatically assigned by the request unit 122 when a reply request or an estimate request for the placement status of the buried pipe is made. The reception date is automatically set from the time stamp when a request for reply to the arrangement status of the buried pipe or a request for quotation is made.

  The property information is site address information, scheduled gas use start date, and land purchase status, and is information input by the user 20 on the input screen 300. Retail business person in charge information is the department, name, e-mail address, and TEL (telephone number) of the person in charge on the retail business side. For example, after the input content entered on the input screen 300 is confirmed on the input confirmation screen, the retailer operator information is registered with the buried pipe information management device 100 by the operator of the retailer, Is set.

  These pieces of project information are stored in the storage unit 112 in association with the buried pipe survey acceptance number (using the buried pipe survey acceptance number as an identifier). The buried pipe survey acceptance number is stored in the storage unit 112 in association with the account of the user 20.

  In the management screen 500, a link for a new case request is provided at the upper left of the screen, and the transition to the input screen 300 can be made from this link. Also, a link to the search screen is provided at the upper right of the management screen 500, and it is possible to transition from this link to the search screen. On the search screen, input of search conditions such as reception date, property information, retail business staff information, etc. is accepted, and on the search result screen, item information corresponding to the input search conditions is displayed in a list.

  In the management screen 500, the buried pipe survey acceptance number is a link to the case details screen. In the case detail screen, in addition to the case information displayed on the management screen 500, the response result of the arrangement status and the estimation result are displayed.

  As described above, the interface unit 120 causes the management screen 500 to display an arrangement status answer result and an estimate result link for each account. In other words, the interface unit 120 generates a management screen 500 that can be accessed for each account, and links to response results and estimation results for arrangement status response requests and estimation requests by accounts that can access the management screen 500. Are displayed in a list on the management screen 500.

  Therefore, the user 20 can easily access desired answer results and estimation results even when there are a plurality of response results and estimation results for response requests and estimate requests made in the past. It becomes possible to improve the property.

  As described above, the conduit business and the retail business that have been operated by the same gas business until now are scheduled to be divided into the retail business 10 and the conduit business 30 after liberalization. As a result, if the retailer 10 becomes unable to know the confirmation of the installation status, the retailer 10 will be informed of the installation status of the buried pipe that would have been accumulated in the conduit company 30 that became a separate company. Information entered at the time of confirmation cannot be obtained.

  Therefore, in the embedded pipe information management apparatus 100, when the interface unit 120 receives input of user information, address information, and the like for each account, the request unit 122 performs both an arrangement status reply request and an estimate request.

  The interface unit 120 can access the answer result and the estimate result with the same account as the account when the user information, the address information, or the like is received. In other words, the interface unit 120 can access the user information, the address information, the answer result obtained by transmitting the address information, and the estimate result by accessing the account when the input of the user information and the address information is accepted. To do.

  For example, when the user 20 directly requests the arrangement answering system 32 from the arrangement answering system 32, the retailer 10 cannot access the user information and address information of the user 20 at that time. , I can not confirm the correctness of the information transmitted at the time of requesting a quote. According to the buried pipe information management apparatus 100, the estimate request is made based on the address information having the same content as the response request for the arrangement status, and the possibility that the estimate request is made with incorrect information can be reduced. .

  In addition, for example, when an arrangement status reply request and an estimate request are made to separate systems, it is necessary to input user information when creating an account for each system. And the risk that different (wrong) user information will be input increases. According to the buried pipe information management apparatus 100, the arrangement status reply request and the estimate request can be executed by the same account, so that it is possible to avoid a situation in which the user information differs between the arrangement situation reply request and the estimate request. .

  Furthermore, when the gas operator before the liberalization receives a reply result indicating that a construction to newly install a buried pipe is required for the installation situation, the gas company estimates the estimate derivation system 34 without receiving a request for an estimate request from the user 20. It was possible to make a request and present the user 20 together with the result of the arrangement status and the estimated result. Whether such a response is to be taken is determined in advance according to the business type of the user 20 or according to a request from the user 20, for example.

  However, after the liberalization, when the user 20 directly requests the arrangement response system 32 from the arrangement answering system 32, the retailer 10 cannot know that there has been an arrangement situation answer request. Therefore, the retailer 10 cannot make an estimate request to the estimate derivation system 34 unless it receives a request for an estimate request from the user 20 to the estimate derivation system 34.

  In the present embodiment, since the buried pipe information management device 100 accepts the response request for the arrangement status, the retailer 10 side can grasp that the response request for the arrangement status has been received. Address information can also be acquired. Therefore, without receiving a request for an estimate request from the user 20 to the estimate derivation system 34, it is possible to make an estimate request to the estimate derivation system 34 and present the result of the arrangement status and the estimate result together to the user. Become.

  As a result, the workability of the person in charge of the retailer 10 can be improved, and a quick and accurate estimate response to the user 20 can be realized, thereby improving convenience.

  In addition, an answer diagram relating to the buried pipe is attached to each answer result and estimate result of the arrangement status, and these answer diagrams or links to the answer diagrams are also displayed on the project detail screen.

  FIG. 7 is an explanatory diagram showing an example of an answer diagram. As shown in FIG. 7 (a), in the arrangement status reply diagram 600, the site indicated by the address information and a map in the vicinity thereof are shown as in the site specifying screen 400, and the site entered on the site specifying screen 400 is displayed. Based on the information, markings (indicated by cross hatching in the figure) for identifying the site are made.

  Further, in the arrangement status reply diagram 600, a buried pipe buried under the road is shown (indicated by a broken line in the figure). For example, in the example shown in FIG. 7A, since a buried pipe is not disposed under the road R in front of the site, a new construction of the buried pipe is required.

  In addition, as shown in FIG. 7 (b), in the estimated response diagram 700, in addition to the arrangement status response diagram 600, a newly installed buried pipe that is the object of construction estimation is shown (in the diagram, the newly installed main branch pipe) Is indicated by a two-dot chain line, and a new extraction pipe is indicated by a one-dot chain line).

  Depending on the location where the extraction pipe is drawn in the site (indicated by a white circle in the figure), the necessity of the new branch and the length of the new branch that needs to be changed will change. In order to increase the accuracy of estimation, lead-in information indicating the position where the take-out pipe is pulled in is also required. Therefore, the interface unit 120 also accepts input of pull-in information on the site identification screen 400.

  In this case, when the request unit 122 receives the response result from the arrangement response system 32, the content that does not require construction for newly installing the embedded pipe based on the position of the existing embedded pipe in the response result and the pull-in information. It is determined whether or not.

  For example, when the buried pipe information management device 100 targets a new construction estimate for the branch pipe among the buried pipes, as shown in FIG. 7B, the position of the road R closest to the position indicated by the pull-in information When the distance D from X to the nearest main branch is equal to or greater than the threshold, the request unit 122 determines that construction for newly installing the main branch is necessary. If the distance from the position X to the nearest main branch is less than the threshold value, the request unit 122 determines that construction for newly installing the main branch is unnecessary.

  Then, the request unit 122 cancels the request for quotation when the reply result of the placement reply system 32 has contents that do not require construction to newly install a buried pipe because of the existing buried pipe in the above-described estimate request process S214. To do. In addition, when the answer result is a content that requires construction, the request unit 122 makes an estimate request.

  As described above, the request unit 122 executes an estimate request to the estimate derivation system 34 based on the answer result of the arrangement answer system 32. Therefore, the reply result of the arrangement reply system 32 can be used and reflected in the estimate request.

  In addition, the request unit 122 cancels the request for quotation when the response result of the arrangement response system 32 does not require construction for newly installing a buried pipe, so that unnecessary processing is avoided and processing load is reduced. As a result, the processing cost can be reduced.

  Further, the request unit 122 determines whether or not the construction for newly installing the buried pipe is unnecessary based on the position of the existing buried pipe in the answer result from the arrangement answering system 32 and the pull-in information. Therefore, it is possible to determine whether or not an estimate request is necessary with high accuracy.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  For example, in the above-described embodiment, a case has been described in which the interface unit 120 displays a link to both the answer result from the arrangement answer system 32 and the estimate result from the estimate derivation system 34 on the management screen 500. However, the interface unit 120 may cause the management screen 500 to display a link to one of the answer result and the estimate result. Further, the interface unit 120 may display a list of one or both of the answer result and the estimation result on the management screen 500.

  Further, in the above-described embodiment, the request unit 122 has explained the case of executing the estimate request or canceling the execution of the estimate request based on the answer result of the arrangement answer system 32. Regardless of the answer result of the system 32, the request for quotation may be executed.

  In the above-described embodiment, when the request unit 122 determines whether or not the construction of newly installing the buried pipe is unnecessary based on the position of the existing buried pipe in the answer result and the pull-in information. Explained. However, the request unit 122 may determine whether or not the construction for newly installing the buried pipe is unnecessary regardless of the pull-in information.

  In addition to the above, the interface unit 120 may display various information necessary for the user 20 when introducing city gas and links to the information on various screens. Here, the information to be displayed on the various screens includes, for example, an application method for introducing city gas, a diffusion rate of city gas in the area indicated by the address information, information on equipment required for introducing city gas, a gas fee, and the like.

  Also provided are a program for causing a computer to function as the buried pipe information management apparatus 100, and a computer-readable storage medium such as a flexible disk, a magneto-optical disk, a ROM, a CD, a DVD, and a BD on which the program is recorded. Here, the program refers to data processing means described in an arbitrary language or description method.

  Note that each step of the buried pipe information management method of the present specification does not necessarily have to be processed in time series in the order described in the flowchart, and may include processing in parallel or by a subroutine.

  INDUSTRIAL APPLICABILITY The present invention can be used for an embedded pipe information management device that provides information related to a gas embedded pipe.
