Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a host computer having a database capable of associating basic map information and basic customer information with each other by a building, and a client connected to the host computer via a network. A client computer processes and processes any information obtained from the database of the host computer by a client computer, and can be taken out in any form.It is used for customer management and presentation to customers in the construction industry. It is a suitable system.

[0002]

2. Description of the Related Art Conventionally, as a data management system of a building using a computer, there is a system capable of linking positional information of a building to a two-dimensional map and managing the owner of the building as customer information.

For example, by inputting a customer's telephone number, building name, or the like, an electronic map near the location of the building is displayed so that the customer or building can be searched or a newly collected customer or building can be searched. The system allows the construction company to manage customers by registering the data of the customer.

[0004]

However, in the building data management system as described above, it is only necessary to manage the data of the existing building, and the information of the building proposed by the builder to the customer, However, it was not possible to manage even the information on the desired building.

In other words, a conventional building data management system focuses on identifying customers (including those who have the potential to become customers) in order to support the business activities of builders. However, since it is not assumed at all that the contractor will efficiently collect and manage information on buildings proposed to the customer and information on buildings that meet the needs of the customer, the architect will I had to redraw the building many times. Although a CAD system has recently been used to save labor in the drawing process, it cannot be denied that the system requires a considerable amount of labor, and it cannot be said that the system is highly efficient.

[0006] Moreover, since a correction according to the customer's request cannot be made immediately on the spot, a correction drawing or the like must be presented to the customer again at a later date, during which the customer's request has changed or changed. If the building is different from what the customer wanted, further changes would have to be made, which would be increasingly inefficient.

Therefore, the present invention not only manages building data associated with map information and customer information, but also proposes a building proposed by a builder to a customer or a building desired by a customer. The purpose of the present invention is to provide a system that can efficiently manage data of non-existent buildings.

[0008]

According to an aspect of the present invention, there is provided a host computer having a database capable of mutually associating basic map information and basic customer information by a building. (3) and a client computer (for example, a local computer 4) connected to the host computer via the network (2). The client computer processes arbitrary information acquired from a database of the host computer. A building data management system (1) capable of being taken out in an arbitrary form, wherein the host computer comprises a parts information database storing at least 3D data and unit prices for each type of parts constituting the building; The computer uses building element information input from outside Building information generating means for generating virtual building information in which the building is regarded as a set of parts based on the building, and replacing the parts included in the virtual building information generated by the building information generating means with other equivalent parts to generate a virtual building. Building information updating means capable of updating information; building visual information generating means capable of presenting visual information of the building by converting the building into 3D based on the virtual building information; and unit price of necessary parts based on the virtual building information And a building cost calculation means for calculating an approximate cost required for the virtual building by integrating the quantity of the virtual building, so that data of a virtual building that is a building proposed to the customer or a building that satisfies the customer's request can be managed. It is characterized by the following.

The data management system for a building thus constructed not only has a database in which customer information and map information are associated with each other, but also inputs element information of the building to a client computer from outside by appropriate means. The building information generating means generates virtual building information as an assembly of parts, and based on the virtual building information, the building visual information generating means displays or prints out 3D visual information of the building on the screen on the spot. Or you can. Further, the cost of the building estimated by the building cost calculating means based on the virtual building information can be displayed on a screen or printed out on the spot.
Further, by replacing the parts included in the virtual building information with other parts according to the customer's request by the building information updating means, the virtual building information can be easily updated. The 3D visual information of the building and the cost required for the building can be displayed on the screen or printed out on the spot.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a building data management system according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a schematic configuration of a building data management system 1 according to the present invention. A host computer 3 and a local computer are connected via a network 2 such as a dedicated line connection LAN or the Internet. 4
The local computer 4 retrieves information stored in the host computer 3 or transmits information for updating data from the local computer 4 to the host computer 3. Although only one local computer 4 is shown in FIG. 1, it is usually used as a configuration in which many local computers 4 can be connected to the host computer 3 via the network 2.

The host computer 3 includes at least a map information master database (basic map information database), a customer information master database (basic customer information database), and a parts information master database (various parts constituting a building). Database).

The map information master database is wide-area electronic map data covering a range used by the local computer 4, and desirably has an area map of a reduced scale capable of specifying the position of a building on the map. The item group includes, for example, “ID” which is a unique number in a database, and “basic attribute number” which allows identification of location information on a map and an attribute related to a building by a unique number consisting of 32 alphanumeric characters. , "Postal code", "residence display", "building name", "lot number display", etc. relating to buildings.

The customer information master database is a database comprising customers (including prospective customers to be sold) and various items relating to the buildings of the customers. The item group includes, for example, “ID” which is a unique number in a database, and “basic attribute number” which allows identification of location information on a map and an attribute related to a building by a unique number consisting of 32 alphanumeric characters. , "Attribute number" that represents the classification of the building (detached house, apartment house, factory, store, etc.) by four digits, "zip code", "residence display", "building name", "lot number display" for the building, Regarding the owner, "owner $ 1""owner address 1-1""owner address 1-2""owner phone number 1""owner name 1" If the building is jointly owned, other owners "Owner $ 2""owner address 2-1"
"Owner address 2-2""Owner phone number 2""Owner name 2""Owner $ 3""Owner address 3-1""Owner address 3-2""Owner phone number 3""Owner name 3", "Construction date", which is the date the building was registered, "Number of floors", which is the number of floors (including the basement) of the building, "Total floor area", which is the total floor area of the building There is a distinction as to whether or not a mortgage has been set for the building and the content of the mortgage, such as "contents of mortgage".

The items managed in the customer information master database are not limited to the above examples, but may be changed as appropriate according to the type of information to be handled, or the number of items may be changed according to the processing performance of the computer. May be appropriately increased or decreased. In addition, when a building is actually constructed upon receiving an order, information relating to the construction can be stored in a database. Such customer building information may be included in the customer information master database, or may be added as an item linkable to the customer information master database, and then added to the host computer 3 as another database (for example, customer building information master database). May be recorded.

The item group of the customer building information described above includes:
For example, a unique number "I
D ”,“ basic attribute number ”that allows identification of location information on the map and attributes related to the building with a unique number consisting of 32 alphanumeric characters, customer identification code (customer registration date, building code, "Customer number" which is a serial number in the order of registration with hyphens), "builder name" which is the name of the builder,
"Contact", "Phone number", "Postal code", "Address 1", "Address 2" as the contact information of the builder, "Sales office" which is the name of the sales office in charge, and "Sales person in charge" which is the name of the sales person in charge "Contractor", the name of the person in charge of construction, "Contracted date", which is the contracted date, "Construction date," which is the date of construction, and the shipping date of parts "Material shipment date",
"End date of first inspection" which is the end date of the first inspection, "End date of the second inspection" which is the end date of the second inspection, and end date of the completion inspection "Date of Completion Inspection" which is the date, "Estimation Number" which is the ID number of the quote database, "Contract Number" which is the ID number of the contract database, and "Completion Drawing Number" which is the ID number of the completion drawing database , "Delivery date", which is the delivery date, and "After maintenance record" to which a record of after maintenance after delivery is added.

The parts information master database is a database of items for each type of parts constituting a building. In addition, even though it is a building part, it is not possible to assemble a building just by combining existing parts like a block toy, so in fact, one that composes one part with construction style and its construction area,
In the present embodiment, a generic name of structural units that can calculate the three-dimensional (3D) and approximate cost of a building, such as a unit made up of a unit such as a bathroom or a kitchen, is a part.

The part group of the part information includes, for example, a unique number “ID” in the database,
"Name" which is the name of the part, "Part code" which is the code number assigned to the part, "Size" which is the size of the part, "Wholesale price" which is the wholesale price of the part, and "Sale" which is the sale price of the part "Price", "3D image data" which is 3D data for displaying a part as a stereoscopic image, and 2D data (display data on a drawing, symbol data, a real image, etc.) for displaying a part on an architectural drawing. "2
D image data "," color information "which is the color information of parts
Etc.

On the other hand, the local computer 4 stores a map information database for storing map information taken from the host computer 3 only in a local area, and stores customer information taken from the host computer 3 only in a local area. It has a customer information database, an original customer information database created as an original database by the local computer 4, and a customer building information database for storing building information of customers who have received orders in the area in which the local computer 4 is responsible.

The item group of the unique customer information includes, for example, a unique number “I” in the database.
D ”,“ basic attribute number ”that allows identification of location information on the map and attributes related to the building with a unique number consisting of 32 alphanumeric characters, customer identification code (customer registration date, building code, "Customer number" which is a serial number in the order of registration with hyphens), "builder name" which is the name of the builder,
You can fill in "Contact", "Phone number", "Postal code", "Address 1", "Address 2", and additional information (family structure, birthday, household income, etc.) obtained by visiting customers as contact information of the builder. "Item 1" is a field where the content can be set freely
To “item 10”.

The customer construction information database includes the same items as the customer construction information managed by the customer information master database of the host computer 3 described above. Since the customer building information is updated at any time according to the order and progress in the area in charge of the local computer 4, the local computer 4 manages the information until the delivery of the property, and thereafter, the host computer 3 It may be managed by.

In the information management in the local computer 4 as described above, for example, it is assumed that the map information database and the customer information database are related with the "basic attribute number" as a common item, and both the customer information database and the customer building information database are " Basic attribute number "
The common customer information database and the customer construction information database are related with "phone number" as a common item. In this manner, the local computer 4 can also extract various information while searching and narrowing it down. For example, based on the unique customer information or the customer building information, the local computer 4 can obtain the information of the customer whose business is targeted. It has a function to display the customer's card in the format of に on the screen and print it out on a paper medium. There is also a function of displaying on a screen a house map or the like of the area narrowed down by the map information database, or printing out on a paper medium.

The above example of printing a customer's card is as follows.
As shown in FIG. 2, for example, a basic attribute number, a customer number, various information of the builder, information on the subject,
Previous management information, information source, building site, property registration information, funding plan, planned cost, contract process results, community-based long-term management data (family composition, DM management, hometown, etc.), database management information such as additional information The layout is displayed as appropriate, and the right half of the page displays the approach process of the salesperson, image data captured from the scanner 5, and the like. Further, the customer number is printed with a bar code so that customer information and the like can be easily taken out from the printed customer card. Further, the customer's card may include a map of the neighborhood where the building is located.

In addition, the local computer 4 has a map information updating function that can update map information based on image information fetched from outside by the scanner 5. For example, map data such as a city planning map, a disaster prevention map, a land price route map, and a district planning map are taken in from the scanner 5, and
By appropriately scaling the captured map data to match the scale of the electronic house map and overlaying the captured map data on the house map as a separate layer, it is possible to forecast future demand in the area, Useful for sales strategy.

Various kinds of new information (information on the loss or new building, various kinds of information obtained about the customer, special circumstances in the area, etc.) collected on the local computer 4 side by visits to the customers, etc. By transmitting the information to the host computer 3, the information in the map information master base and the customer information master database can be updated, and the host computer 3 constantly stores the updated latest information.

However, when updating data, if the original data is overwritten and lost due to erroneous information resulting from an erroneous input or the like, the reliability of the database is lost, so that human or mechanical A check mechanism is provided as appropriate to prompt the local computer 4 to re-enter the updated data with low credibility, or to save the information before update as a backup and When such data has been recorded, it is desirable to take measures such as restoring from the backup data to the immediately preceding state, so as to enhance the reliability as the master database.

Further, the local computer 4 is provided with a presentation system for giving a presentation to a customer. This presentation system is composed of a whole of subdivided systems (3D-CAD system, interior seat system, exterior seat system, estimation / estimation system, apartment balance plan creation system).

First, the 3D-CAD system is, for example,
A hand-drawn floor plan created in accordance with a certain creation style is taken in from the scanner 5, and image processing is performed so as to diffract it as “building element information”, thereby generating virtual building information that is regarded as a set of parts. It has a function, a function of updating virtual building information by replacing parts included in a virtual building with other equivalent parts, and a function of generating visual information obtained by converting the building into 3D based on the virtual building information. That is, the 3D-CAD system can virtually assemble a building from information input from the outside, display the exterior and interior of the virtual building on a screen, or print out the paper on a paper medium.

The form of the building element information created by the sales representative or the like in order to cause the 3D-CAD system to generate the virtual building information is not particularly limited, and the floor plan according to a certain form is not limited. It does not have to be handwritten. Anyway, it suffices if the minimum information required to generate the virtual building information can be input to the 3D-CAD system as “building element information”, and the virtual building information can be input according to the input “building element information”. By appropriately setting an algorithm that can generate a virtual building information, a function of generating virtual building information can be realized. In addition, when generating virtual building information, not only the method of selecting parts for each minimum unit, but also a group of parts and units is registered as a basic system configuration, and the system configuration of such a large unit is registered. If the virtual building information is generated by preferentially using, the CPU load on the local computer 4 can be reduced and the processing time can be shortened.

As described above, after the virtual building information is generated by the 3D-CAD system, the parts included in the virtual building information are replaced with other equivalent parts, thereby updating the virtual building information itself. Since the 3D visual information is regenerated based on the updated virtual building information, the external appearance and the interior of the virtual building accompanying the part change can be immediately displayed on a screen or printed out on a paper medium.

Further, the interior sheet system uses interior information (names and images of interior parts such as wallpaper and doors used in the virtual building) included in the virtual building information created by the 3D-CAD system. It is displayed on a screen in a layout according to a predetermined arrangement format or printed out on a paper medium. When the virtual building information is updated, the interior information is also updated, and the image data of the interior is changed accordingly. When the number of interior parts to be displayed increases or decreases, an appropriate layout is selected based on preset selection conditions according to the interior type and the number of displays, and an interior sheet is created.

Further, the exterior sheet system uses exterior information (outer walls, roofs, gutters, etc. employed in the virtual building) included in the virtual building information created by the above 3D-CAD system.
This is for displaying the names and images of exterior parts such as shutters, windows, and verandas) on a screen in a layout according to a predetermined arrangement format, or printing them out on a paper medium. When the virtual building information is updated, the exterior information is also updated, and the image data of the exterior member is changed accordingly. Also, if the number of exterior parts to be displayed increases or decreases,
An appropriate layout is selected based on preset selection conditions, and an exterior sheet is created.

In the local computer 4 having the above-described 3D-CAD system, interior sheet system, and exterior system, a presentation sheet for giving an effective presentation to a customer can be easily created and updated.

This presentation sheet presents a proposed building to the customer in a highly apparent manner based on the virtual building information, and is displayed on the screen as an image that makes it easy to grasp the appearance and interior of the building. Or print out on paper media. Printing examples of the presentation sheet are, for example, as shown in FIGS.

More specifically, a perspective view of the virtual building also serving as the cover of the presentation sheet (see FIG. 3), an east elevation, a west elevation, a south elevation, and a north elevation of the virtual building are shown. Elevated view laid out on a page (see FIG. 4), layout drawing of virtual building on site (see FIG. 5), plan view laid out on the first floor plan and second floor plan (see FIG. 6), appearance Perspectives (see FIG. 7) Perspective views such as 1st floor entrance, 1st floor entrance, 1st floor Western room 1, 1st floor Western room 2, 2nd floor corridor, 2nd floor hall, 2nd floor Western room, 1st floor Western room 2 (see FIG. 8) ), Interior sheets (surrounding edge, closet, panel door, entrance storage, window frame, etc.) laid out in a plan view (see Fig. 9), exterior parts (outer wall materials, roof specifications, windows, decorative borders, balconies, entrances) Etc.) to the appearance path Out the exterior sheet (see FIG. 10), the internal equipment (kitchen, bathroom, toilet, sanitary, etc.) (see FIG. 11) equipment specifications sheet showing the real image of the electrical equipment (lighting equipment, fully automatic water heater,
A set of presentation sheets is composed of electric equipment sheets (see FIG. 12) showing actual images of TV intercoms and the like.

As a presentation sheet,
In addition, a bird's-eye perspective view of the first and second floors may be added to make it easier to grasp the internal image of the building. Also,
Not only drawings and images but also structural items, external finishes, internal finishes, internal fittings, electrical equipment, internal features, water supply facilities, and other classifications are presented in a list form with their constituent items and their specifications. You may do it.

Furthermore, since the quantity of each part can be integrated based on the virtual building information generated by the 3D-CAD system and the unit price of each part can be taken out from the parts information database, the approximate cost required for the virtual building can be calculated. Can be. Therefore, in the present embodiment, an integrating / estimating system is provided in the presentation system of the local computer 4 to have a function of calculating an approximate cost required for the virtual building.

FIGS. 13 to 15 show print examples of the first to third pages (final page) of the quotation sheet prepared by the multiplication / estimation system.
Foundation work, wood work, external finishing work, internal finishing work, external fitting work, internal fitting work, external parts work, internal parts work, kitchen equipment work, plumbing and sanitary equipment work, gas equipment work, electric equipment work, and other works , Various expenses, and separate expenses were used. The details of each construction are shown on the second and third pages.

The cost calculated by the multiplication / estimation system is not limited to the simple total value of the unit prices of the parts that make up the virtual building, but is a set of works ranked according to the grade of the parts to be used and the equipment used. May be selected. Such a method of calculating the construction cost is used for kitchen facility construction and distribution board construction, and the distribution board price and the like that vary depending on the price of the system kitchen to be installed and the number of circuits are included in the construction cost.

Further, the above-described estimation / estimation system can not only create a quote to be presented to the customer, but also divert the specifications of the work and the quantity of parts required when ordering the work. . That is, when an order is received for a building presented to a customer as a virtual building, various information necessary for actually building the virtual building is immediately sent to the material department and the construction department connected via the network 2. And a system with excellent immediacy and reliability. This eliminates the need to spend unnecessary time, as in the case of picking up construction items from design drawings and integrating them as in the past, as well as the risk of human errors such as picking up items and counting errors. No, the reliability as a system is also increased.

When the virtual building proposed to the customer is a rental property such as an apartment or a condominium, an estimate of the income and expenditure of the rental can be presented to the customer with high persuasiveness.
The presentation system of the local computer 4 is provided with an apartment balance plan creation system, which can display an apartment balance plan proposal on a screen or print out a paper medium.

Print examples of sheets included in the apartment balance plan proposal are shown in FIGS. 16 to 21. A sheet listing the property outline, registration costs, budget plan, and borrowing plan (see FIG. 16) ), A sheet listing the rental plan, the total for each room type (see FIG. 17), and a sheet listing the rental conditions, operating conditions, tax conditions, taxes, etc. (FIG. 18).
), Income and expenditure, expenditure and expenses, income and expenditure, and profit and loss list for each year (for example, see FIG. 19 showing the first to ten years), and the horizontal axis from the first year to, for example, 30 years As a bar chart and a line graph showing the transition of income and expenditure and the cumulative balance (see FIG. 20), interest rate, repayment principal, repayment interest, repayment amount, repayment amount, borrowed money balance, etc. Is compiled for each year (see FIG. 21).

In addition, the income and expenditure transition diagram showing the transition of income and expenses and the annual profit and loss with a bar graph and a line graph with the horizontal axis from the first year to, for example, 30 years, the cumulative balance and the borrowed balance For example, a property state diagram that graphs a state in which the property is accumulated from the property may be included. Also, in the illustrated apartment budget plan proposal, the repayment of the borrowed money is assumed to be 25 years, and the transition after about 30 years to show the profit and property status to the customer after the full repayment of the borrowed money, It may be appropriately increased or decreased according to the repayment period of the borrowed money.

As described above, in the building data management system 1 according to this embodiment, the local computer 4 as a client computer connected via the network 2 to the host computer 3 having various basic master databases. Having a map information database, a customer information database, a unique customer information database, a customer building information database, and a presentation system, it is possible to select and identify customers in a sales area in which the local computer 4 is in charge, and to be suitable for sales support. You can display and output a customer's card that summarizes necessary items, and create and display and output a presentation sheet, estimate, and apartment balance plan that are effective for presentation to customers.

In addition, during sales activities for customers,
By accumulating and accumulating customer information and daily sales reports, etc. obtained by the sales representatives in a database, it is possible not only to easily check the sales contents and results of individual sales representatives, but also to manage all sales representatives collectively. It can be done easily. Further, if the business activity status in the area can be processed and displayed on a graph or map display, it is effective for strategy planning for the entire area.

In addition, since arbitrary information can be taken into the local computer 4 from the scanner 5, memos created by a salesperson visiting a customer and area information collected by the salesperson are taken as electronic information. The database can be linked to map information and customer information. This will make it easier to retrieve and process information, improve customer satisfaction by providing appropriate services in line with customer requests, and develop a sales strategy that is in line with the future prospects of the area. it can.

Therefore, according to the building data management system 1 of this embodiment, the local computer 4
However, since the customer management in the assigned area can be realized as a whole, the sales activities of the salesman and the management of the building or the like to be sold can be realized in an integrated manner, so that the system is suitable for sales support.

In the building data management system 1 shown as an embodiment, an example in which the host computer 3 and the local computer 4 are connected to the same network 2 has been described. It is not limited. For example, a local server having only a database of information handled in the local area is deployed at a regional branch office using a server in the head office of the company as an integrated host computer, and various types of information processing are performed on client computers that can use the database of the local server. The system may be configured to have a system, or a mirror server having the same database as the host computer may be arranged on the network, and the client computer may use the database from the mirror server.

Further, if various functions of the local computer 4 are made available from a portable terminal device possessed by each sales representative via a telephone line or the like, the portable terminal device receives and displays the processing results of the local computer.・ Since it is only necessary to have the ability to output, a computer with relatively low processing performance and small storage capacity can be used as a mobile terminal device, and a mobile terminal device that a salesperson brings to a customer's home is inexpensive. -It can be reduced in weight.

Next, using the building data management system 1 according to the present embodiment, a series of flows from the identification of a prospective customer to the ordering, construction start, and delivery through presentation will be specifically described.

First, on the electronic house map of the business area, "and search" is performed using "town name", "age of construction", "construction method" or the like as a search item, and a list of customers who match these is displayed on the screen, for example. A list is displayed in the upper separate window, and each building on the electronic house map that matches the "basic attribute number" of the customer is displayed on the screen in a colored state. In the case where no customer satisfying the above search condition is hit or the number of hits is too large, the same operation is repeated while changing the search condition.

The extracted customer is recorded in the unique customer information database together with other customer information after adding the identification code of the prospective customer as the original customer handled by the local computer 4, that is, the unique customer. From the original customer information database created in this way, a customer's card of a prospective visitor is printed, and map information of a place of residence to be visited is printed. What sales representatives learned after visiting the prospect,
The original customer information database is updated by inputting the information in the free entry as needed.

When creating a virtual building proposed to a promising customer, a hand-drawn floor plan is drawn on a dedicated sheet, which is taken into the local computer 4 from the scanner 5, and the virtual building as a set of parts is obtained from the taken image. Creates information and parses the virtual building based on this information.
Create a presentation sheet including a bird's eye view, plan view, elevation view, interior sheet, exterior sheet, etc., and present it to the customer.

It should be noted that information on the interior and exterior cannot be specified only from the hand-drawn floor plan.
For example, a list of necessary parts (interior / exterior) derived from the floor plan is displayed in a table format, and this table is selected from the parts in the part information database and the necessary parts are filled in. Go to specific. Thus, the parts are displayed on the screen in a format in which each part is arranged at a predetermined position on the interior sheet and the exterior sheet. As described above, in this system, “building element information” required to create virtual building information
Since a handwritten floor plan is used as one of the factors, element information that cannot be specified in the floor plan is input to the local computer 4 by performing a separate operation.

Then, while looking at the screen of the presentation sheet or the printed paper, incorporating the customer's requests and proposals, the virtual building information is changed in units of parts (or composite units), and finally the customer is changed. Once completed as a virtual building that satisfies the needs of the above, while presenting the completed presentation sheet to the customer,
Create a quote or apartment plan.

Based on the created quotation and the apartment balance plan, the customer and the sales representative take into consideration various conditions (whether they can cover their own funds or borrowed money, whether they can manage the apartment, etc.)
If necessary, the parts are changed again to update the virtual building information. When the virtual building information is updated by replacing parts, the estimated amount of the quote is automatically updated according to the unit price of the changed parts, so consider using the estimated cost required for the updated building. I will repeat. In addition, the apartment income and expenditure plan is updated not only in accordance with an increase or decrease in the construction cost, but also by increasing or decreasing the amount of the “assumed rent”.

When the contract is made in the virtual building proposed to the customer as described above, the actual construction work is performed. At this time, all parts and finishing specifications required for construction are digitized as virtual building information, so construction can be ordered as it is, and the construction site is also displayed on the house map extracted from the map information database. Since it can be shown and arranged, the work can be advanced efficiently. Moreover, the progress of the construction and the items to be confirmed are added to the unique customer database and the customer building information database, so that the progress of the construction can be efficiently managed.
In addition, since the details and progress of sales to the customer in charge by the sales person are also recorded, the recorded contents can be used by the supervisor in charge of sales to give instructions to enable more effective sales. it can.

Further, after delivery, after-sales maintenance and periodic inspections are added to the original customer database and customer building information database, so that customer information can be further accumulated and used for subsequent sales activities. Can be.

Therefore, a specific flow from the identification of a customer who has received an order in the past, such as rebuilding or expansion, to the conclusion of a contract after presentation, will be specifically described.

First, for only the in-house customers for which the “customer number” is set in the customer information master database of the host computer 3, the “town name” and “building year” of the house display are displayed on the electronic house map of the sales area. When “and search” is performed using “income”, “other land”, etc. as search items, a list of customers that match these is displayed in a separate window on the screen, for example, and the “basic attribute” of the customer is displayed. Each building on the electronic house map that matches the "number" is displayed on the screen in a colored state. In the case where no customer satisfying the above search condition is hit or the number of hits is too large, the same operation is repeated while changing the search condition.

Then, the extracted in-house customer is recorded as a new business target customer in the unique customer information database together with other customer information after adding a prospective customer identification code. From the original customer information database created in this way, DMs for participation in seminars and site tours are sent, and sales representatives visit prospective customers. The information obtained after the visit is entered into the free entry as needed, so that the unique customer information database is updated.

When creating a virtual building to be proposed to a promising customer, a hand-drawn floor plan is drawn on a dedicated sheet, which is taken into the local computer 4 from the scanner 5, and the virtual building as a set of parts is obtained from the taken image. Creates information and parses the virtual building based on this information.
Create a presentation sheet including a bird's eye view, plan view, elevation view, interior sheet, exterior sheet, etc., and present it to the customer.

In the case of an in-house customer, since detailed customer building information on the building built at the time of the previous contract is recorded in the database, this is effectively used to perform a virtual remodeling. A building can be suggested. In other words, while comparing the current elevation plan with the proposed elevation plan, the benefits of extension and remodeling can be appealed,
Calculate and compare the “revenue and expenditures from the current fiscal year on the income and expenditure plan table presented last time” with the “revenue and expenditure plan for apartments after the current year when rebuilding this year”. It can be shown as a comparison table before and after rebuilding, and a more persuasive presentation can be made.

Next, while looking at the screen of the presentation sheet or the printed paper, incorporating the customer's requests and proposals, the virtual building information is changed in units of parts (or composite units), and finally the customer is changed. Once completed as a virtual building that satisfies the needs of the above, while presenting the completed presentation sheet to the customer,
Create an estimate, apartment budget plan, and comparison table before and after rebuilding.

The created estimate, apartment balance plan,
According to the comparison table before and after the rebuilding, the customer and the sales representative take into account various conditions (whether they can finance with their own funds or borrowed money, whether there is no difficulty in apartment management, etc.), change the parts again if necessary, Update building information. After the contract is concluded with the virtual building proposed to the customer, after that, in the same way as for the non-customers described above, ordering and process management of construction work based on the virtual building information, and after-sales after delivery And regular maintenance is recorded in the database as needed.

As described above, for a customer who has made a contract as an in-house customer, past customer information becomes an extremely effective asset and can be effectively used in presentations and the like.

As described above, the building data management system according to claim 1 of the present application not only includes a database in which customer information and map information are associated with each other, but also externally transmits building element information from outside. The building information generating means generates virtual building information as a set of parts based on the input to the client computer, and the building visual information generating means generates 3D visual information of the building based on the virtual building information. It can be displayed on the screen or printed out on the spot. Also,
The cost of the building estimated by the building cost calculation means based on the virtual building information can be displayed on a screen or printed out on the spot. Further, by replacing the parts included in the virtual building information with other parts according to the customer's request by the building information updating means, the virtual building information can be easily updated. The 3D visual information of the building and the cost required for the building can be displayed on the screen or printed out on the spot.

That is, by managing data of a building proposed by the builder to the customer or a building desired by the customer, which does not actually exist, as virtual building information that is regarded as an assembly of parts. Not only can the visual information and the estimated cost of the virtual building be presented immediately, but even if a change is made according to the customer's request, the visual information and the estimated cost of the virtual building according to the change are presented immediately. And have a very high effect on the efficiency of sales activities.
