That is, the information right holder ID, the information ID, and the building information are associated with each other and stored in the database 12. The building information stored in the database 12 in the same format as the stock information 231 is associated with a plurality of information right holder IDs and information IDs. For example, in the case of equipment such as equipment that is mass-produced, if the equipment is of the same type, building information such as an instruction manual is often shared by a plurality of equipment. In such a case, the storage capacity required for the database 12 can be reduced by associating a plurality of information rights holders with the same building information and storing them in the database 12. Moreover, when updating the contents of building information, it is only necessary to update the contents of one building information associated with a plurality of information right holder IDs and information IDs. Can be made easier.

  When information is stored in the database 12 in the same format as the stock information 232, a plurality of building information is associated with one information right holder ID and information ID. This is because new building information may be generated by renovation or maintenance. Such association is suitable when it is desired to save past building information instead of overwriting past building information over new building information.

  Next, each of the building information, information ID, and permission in this embodiment will be described. The building information in this embodiment includes design information including building design drawings, construction information including construction drawings and building specifications (materials used, etc.), equipment equipment design documents, specifications, instruction manuals, etc. Equipment information including energy, energy information indicating real-time usage or usage charges for electricity, gas, water, etc., and crime prevention information.

In the example of FIG. 6, the upper two digits of the information ID are identification codes indicating the type of information (for example, 00 is a design drawing, 01 is a construction drawing, etc.), and the remaining numbers are the identification codes. Is an individual code for identifying information of each individual in the given information. Building information is uniquely specified by the identification code and the individual code.

  In addition, when new building information is generated by renovating buildings or repairing equipment, a different individual code is assigned each time building information is generated, but each building information can be identified. If possible, it is not limited to this. For example, when the content of existing building information is updated, the individual code of the updated building information is made the same as before updating, and information indicating the date and time when the building information is updated is added, thereby identifying the building information You may make it do. In addition, when an IC tag is attached to the equipment, the identification information of the IC tag may be used as an information ID of equipment information that is one of the building information.

  FIG. 7 shows the contents of the permission. A permission is set as a viewing authority for each identification code, that is, for each type of building information. In FIG. 7, A indicates an information rights holder, B indicates an investor, and C indicates a remodeling company or a maintenance company. Further, D indicates an information viewer, and any building information cannot be viewed by the information viewer with the initial permissions shown. As will be described later, the permission for the information viewer is changed to the permissions set in A to C in FIG. 7 at the start of the information browsing, and again after the information browsing is completed. The permissions are changed to those set in D. In this way, security can be improved by setting permissions for each type of industry and restricting access to building information.

  Next, the schematic operation of the building information management system will be described with reference to FIG. In the present embodiment, mainly when registering a member of a service provided by the building information management system, registering a link generated by the information management input server 10, changing a permission, browsing information When a person browses information, when new building information is generated, when a link is added, when a link breaks due to corporate bankruptcy, etc., when an information rights holder is changed, and when a building is demolished At times, each computer terminal constituting the building information management system operates.

Similarly, the browser terminal 3 and the right holder terminal 4 transmit member registration information to the system management server 2 via the network 500 (steps S806 and S809). After receiving this member registration information, the system management device 20 of the system management server 2 generates an ID and a password, and stores them in the member database 21 together with the member registration information (step S814).

  After registering as a member, the information input person device 11 of the information input person server 10 generates link information related to the link to the building information stored in the database 12 and transmits it to the system management server 2 via the network 500 ( Step S802). The system management device 20 of the system management server 2 receives the link information and stores it in the link database 22 (step S816).

  At the time of browsing information, the browser terminal 3 transmits an information browsing request to the system management server 2 via the network 500 (step S807). The information browsing request is also transmitted to the right holder terminal 4 by the system management server 2. In the right holder terminal 4, the information right holder determines whether to permit browsing of information. When permitting browsing of information, the right holder terminal 4 notifies the system management server 2 of permission to browse information (step S810). The system management device 20 of the system management server 2 browses the information stored in the member database 21 in order to enable browsing of information by the browser terminal 3 when the right holder terminal 4 is notified of permission to browse the information. The user's permission is changed (step S816).

  After the permission is changed, an information browsing request is transmitted from the browser terminal 3 to the system management server 2. The system management device 20 of the system management server 2 receives the information browsing request and transmits information including the server address related to the link to the information input person server 10 to the browser terminal 3 (step S817). The browser terminal 3 receives the information, accesses the information input person server 10 having the server address included in the information, and acquires building information. The building information is displayed on the terminal by, for example, the web browser of the browser terminal 3 (step S808).

  When adding a link, the right holder terminal 4 transmits a link addition request to the system management server 2 via the network 500 (step S811). Further, the information input person device 11 of the information input person server 10 generates new building information and stores it in the database 12 (step S803). The system management device 20 of the system management server 2 receives the link addition request from the right holder terminal 4, and stores new link information in the link database 22 (step S818).

  When a link break occurs, the information input person device 11 of the information input person server 10 transmits a link break notice to the system management server 2 in advance and uses the building information stored in the database 12 as the system management server. 2 (step S804). The system management device 20 of the system management server 2 receives (downloads) the link break notification and the building information, and stores the building information in the stock database 23 (step S819).

  When the information rights holder is changed, the rights holder terminal 4 transmits an information rights holder change notification to the system management server 2 (step S812). The system management device 20 of the system management server 2 receives the information right holder change notification and updates the contents of the member database 21 (step S820).

  When the building is dismantled, the right holder terminal 4 transmits a dismantling notice to the system management server 2 (step S813). The system management device 20 of the system management server 2 receives the dismantling notification and rewrites the contents of the member database 21, link database 22, and stock database 23 relating to the building to be demolished (step S821). The dismantling notification is also transmitted to the information input person server 10 by the system management server 2. The information input person device 11 of the information input person server 10 receives the dismantling notification and rewrites the contents of the database 12 related to the building to be dismantled (step S805).

  Next, the detailed operation of the building information management system at the time of member registration will be described. First, the operation when the information input person performs member registration will be described with reference to FIG. In the information input person server 10, a Web browser is activated by a user (information input person). When the user inputs information via the operation unit of the information input person device 11, the control unit of the information input person device 11 performs each process based on the information. When the information input person device 11 accesses the system management server 2, an existing Web communication technology is used. That is, the information input person device 11 inquires a DNS (Domain Name System) server (not shown) for a domain name included in the URL of the system management server 2 via the network 500, and the IP address of the system management server 2 from the DNS server. To get.

  The information input person device 11 transmits a message indicating a request for Web information to the IP address. The system management server 2 receives this message and transmits a message including Web information such as an HTML document to the information input person apparatus 11 based on the content of the message. This message is received by the information input person device 11, and the content is analyzed by the Web browser of the information input person device 11. The Web browser displays a Web page based on the message received from the system management server 2 on the display unit. HTTP is used for sending and receiving the above message. The system management server 2 includes a program such as CGI (Common Gateway Interface) that performs dynamic processing, and performs processing in response to a request from the information input person device 11. The above processing is the same when the browser terminal 3 and the right holder terminal 4 access the system management server 2.

  First, the information input person device 11 transmits member registration information to the system management server 2 (step S901). This member registration information includes the company name, address, contact information, server address, and type of business (including information indicating that the person has entered the information). In the system management server 2, the communication control unit 200 receives the member registration information and outputs it to the member information management unit 201.

The stock data management unit 208 stores the building information, information right holder ID, and information ID included in the transmission information in the stock database 23.

  Subsequently, the stock data management unit 208 searches the member database 21 for information input person information of the information input person that is broken, based on the information input person ID acquired in step S1701 or step S1703. Then, the stock data management unit 208 rewrites the server address in the information input person information with the address of the system management server 2 (step S1704). As a result, when browsing information, the browser terminal 3 accesses the system management server 2 instead of the information input server 10. Thereby, even when an information input person (information input person server 10) does not exist, presentation of building information to an information viewer can be continued.

  Next, the operation when the information right holder is changed because the owner or resident of the building has changed will be described with reference to FIG. Prior to the change of the information rights holder, the rights holder terminal 4 of the current information rights holder generates an information rights holder change notification for notifying that the information rights holder is changed, and transmits it to the system management server 2 (step S1801). ). This information rights holder change notification includes the name and address of the current information rights holder and the name and address of the new information rights holder. The system management device 20 of the system management server 2 receives the information right holder change notification, and displays, for example, a message for notifying the administrator of the building information management system of the change of the information right holder on a display unit (not shown). indicate.

  When the information rights holder is changed due to the surrender of the building or the like, the new information rights holder is notified of information for encouraging membership registration. For example, a direct mail or the like is transmitted from the administrator who confirmed the change notice of the information rights holder to the new information rights holder. When the new information right holder decides to become a member who uses the service provided by the building information management system, the right holder terminal 4 sends the member registration information to the system management server based on an instruction from the new information right holder. 2 (step S1802). This member registration information includes the owner name, address, and contact information of the new information right holder, and more preferably includes the information right holder ID of the old information right holder.

  The communication control unit 200 of the system management server 2 receives the member registration information and outputs it to the member information management unit 201. The member information management unit 201 searches the member database 21 for relevant information right holder information based on the address or information right holder ID included in the member registration information. If there is information right holder information that matches the conditions, the system management device 20 rewrites the landlord name and contact information in the information right holder information with the information of the new information right holder (step S1803). Subsequently, the member information management unit 201 instructs the member identification information management unit 202 to generate an ID and a password. The member identification information management unit 202 generates an information right holder ID and password, associates the information right holder ID and password with the member registration information already stored in the member database 21, and stores it in the member database 21 (step S1). S1804).

  Subsequently, the member identification information management unit 202 outputs the generated information right holder ID and password to the communication control unit 200. The communication control unit 200 transmits the information right holder ID and the password to the right holder terminal 4 (step S1805). The right holder terminal 4 receives the information right holder ID and the password, and stores them in a storage unit (not shown). The information right holder ID is also transmitted to the information input person server 10 and is stored in the database 12 in association with the building information by the information input person device 11 of the information input person server 10. In the above description, the right holder terminal 4 of the old information right holder transmits the information right holder change notification, but the right owner terminal 4 of the new information right holder may transmit the information right holder change notification.

  Next, the operation | movement at the time of the demolition of a building is demonstrated using FIG. The right holder terminal 4 generates a dismantling notification for notifying the dismantling of the building and transmits it to the system management server 2 (step S1901). This dismantling notification includes an information rights holder ID and a password. The communication control unit 200 of the system management server 2 receives the disassembly notification and outputs it to the member identification information management unit 202, the member information management unit 201, the link information management unit 206, and the stock data management unit 208. After the member identification information management unit 202 performs the above-described authentication based on the information right holder ID and the password, the member information management unit 201 rewrites the contents of the member database 21. That is, the member information management unit 201 searches for information right holder information associated with the same information right holder ID as the information right holder ID included in the dismantling notification, and deletes the information right holder information (step S1902).

  The link information management unit 206 rewrites the contents of the link database 22. That is, the link information management unit 206 searches for link information associated with the same information right holder ID as the information right holder ID included in the dismantling notification, and deletes the link information (step S1903). The stock data management unit 208 rewrites the contents of the stock database 23. That is, the stock data management unit 208 searches for stock information associated with the same information rights holder ID as the information rights holder ID included in the dismantling notification, and deletes the stock information. However, when other information right holder IDs are also associated with the same stock information, the stock information is not deleted, and only the information right owner ID same as the information right owner ID included in the dismantling notification is deleted ( Step S1904).

  Subsequently, the stock data management unit 208 generates a dismantling notice for notifying the dismantling of the information right holder's building and transmits it to the information input person server 10 (step S1905). This dismantling notification includes the information right holder ID of the information right holder of the building related to the dismantling. The information input person device 11 of the information input person server 10 receives the disassembly notification and rewrites the contents of the database 12. In other words, the information input person device 11 deletes the building information associated with the information right holder ID that matches the information right holder ID included in the dismantling notification (step S1906).

  As described above, in the building information management system according to the present embodiment, the information input person (information input person server 10), the information viewer (viewer terminal 3), and the information right holder (right holder terminal 4) They are linked via the management server 2. Further, the system management server 2 transmits the server address of the information input person server 10 that manages the building information to the browser terminal 3 in response to the browsing request from the browser terminal 3, and the browser terminal 3 The information input person server 10 having an address is accessed to acquire building information. As a result, the information viewer can easily obtain the building information as compared with the conventional case where the building information has been scattered, so that the building information can be effectively used. For example, when the information viewer is a remodeling company, a maintenance company, or the like, the information viewer can efficiently work using the acquired building information.

  Moreover, according to this building information management system, information distribution can be promoted and the value of a building can be improved. For example, when the information viewer is an investor, the investor can more accurately evaluate the building using the acquired building information. As a result, it is expected that investors will have more investment opportunities and that investment activities for buildings will become more active. As a result, the owner of the building can obtain an economic benefit that the value of the building is improved.

  If the value of the building is improved, the distribution of houses and the like is promoted, and economic and environmental benefits are generated. The reason is that the development of information on housing, etc. and the formation of an investment market for buildings will make building values more understandable and reduce the economic risk of purchasing housing. .

  The building information management system is characterized in that the system management server 2 does not store and manage building information but manages information for accessing (linking) the information input person server 10 that manages building information. It has. As in the prior art (see, for example, Patent Document 1 and Patent Document 2), in a form in which a single management server manages information centrally, an enormous storage capacity for storing information is required, and system management is performed. There is a problem that it costs more. On the other hand, according to the building information management system, the storage capacity required in the system management server 2 by the distributed management of the building information by each information input person server 10 and the link management by the system management server 2 is as follows: The amount may be smaller than that in the form of centrally managing information. As a result, the cost on the management side of the system can be reduced.

  Furthermore, in a form in which a single management server manages building information in a unified manner, when a new service appears, it matches the service (more specifically, the format of building information generated by the service, etc. Therefore, it is necessary to change the structure of the database, the data storage method, and the like. On the other hand, according to the building information management system, even when a new service appears, the system management server 2 only needs to add a link, so that the system configuration does not change significantly. A service provider or the like that provides a new service can be incorporated into the service of the building information management system to continue the service.

  Furthermore, the responsibility related to building information should be borne by the information input person (supplier) who generated it, and the information input person server 10 owns the building information as in this building information management system. However, the location of responsibility becomes clearer. As a result, the system management server 2 can concentrate on the position of the supervisor of the information input person server 10 as a position independent of the information input person server 10.

  Also, in this building information management system, the information viewer cannot browse all building information, but permission is set according to the business type of the information viewer, and certain restrictions are imposed on browsing. As a result, security can be improved and information management can be enhanced.

  In the building information management system, when the link to the information input person server 10 disappears, the system management server 2 acquires and manages the building information managed by the information input person server 10. Then, the link destination associated with the building information is changed to the system management server 2. Thereby, the information viewer can continue browsing the building information.

  The embodiment of the present invention has been described in detail above with reference to the drawings, but the specific configuration is not limited to this embodiment, and includes design changes and the like within a scope that does not depart from the gist of the present invention.
