<< Second Embodiment >>
<< System configuration and server system >>
FIG. 2 is a block diagram showing the overall configuration of the construction site management system according to the second embodiment of the present invention, and FIG. 2 is a block diagram showing the configuration of the site office system provided at the construction site and the site portable system connected thereto. 3 shows.

  As shown in FIG. 2, the construction site management system of the second embodiment exemplifies the case where the present invention is applied to one construction company. The head office server system 100 that forms the core of the system, the branch office, A client system 200, a field office system 300, and an external organization system 400 provided in a client company, a design office, or the like are connected to each other via the Internet NW. In this case, instead of the Internet NW, mutual connection can be made via a public line or a dedicated line.

  The head office server system 100 further includes, for example, a client system installed in a conference room 100A in the head office or a process management department via the head office intranet INT, or another business management server 170 used for personnel management, material management, or the like. It is connected to the head office individual system.

  The head office server system 100 mainly comprises a video storage / transmission server 110 and a video conference system server 120, and each base connected to each other by an information / data sharing function in the building site management system and a network such as a head office or a branch office. Information communication function.

  The video storage / transmission server 110 receives video data transmitted from a video camera (for example, a video camera provided in a site portable system 350 to be described later) installed at a construction site and receives a hard disk drive (HDD) or the like (not shown). Accumulate in storage. The stored video data is encoded and compressed in advance by the encoder / decoder 112 (eg, MPEG-4 format) so that the capacity of the storage device can be used effectively. In addition, the server 110 can distribute video data transmitted from a local video camera or the like in real time to the client system in the head office conference room 100A and other base client systems such as the branch client system 200. it can. In this case, since the distributed video data is distributed to each client system in a coded and compressed state, network traffic required for video data transmission can be reduced. Since the encoded compressed video data transmitted to each client system is decoded and displayed by a corresponding decoder installed in the client system, specific on-site video is simultaneously transmitted between the headquarters, branch offices, site offices, etc. Can be shared.

  Next, the video conference system server 120 provided in the head office server system 100 will be described. This video conference system server 120 is connected to the Internet NW through the secure server 122 to video conference clients provided at each site such as the client system of the in-house conference room 100A, the branch client system 200, the field office system 300, and the external organization system 400. Connected via the network. The secure server 122 encrypts and distributes the video / audio data from each client mediated by the video conference system server 120, thereby preventing the content of the conference from leaking via the network.

  The video conference system server 120 further provides document file sharing and application sharing functions. In other words, the video conference system server 120 is linked to the document database 124 and / or the CAD database 126, and is stored in the word processor document file, spreadsheet file, presentation file, or CAD database 126 stored in the document database 124. The CAD data file can be shared between client systems at each site. At the same time, by the application sharing function, for example, application software installed in a client system at a certain base but not installed at another base (for example, presentation software is installed in a computer at a certain base). In the case of a case where it is not in a computer at another base, it can be operated as if it is implemented in a client system in which it is not implemented.

  In this embodiment, a paper filing emulator 130 is mounted on the server system in order to manage the document files stored in the document database 124 described above. The emulator 130 is an application software that incorporates a real-world document management method of punching a paper document, binding it into a predetermined binder, and storing it as an intuitive graphical user interface for electronic management of document files. is there. Normally, a file management tool installed in a computer OS is used to operate a document file such as a word processor document on a computer. The emulator 130 here displays an image of a paper binder as a metaphor on a computer display. In addition, by dragging and dropping a specific document file on a paper binder image while displaying a specific document file, a user interface is provided as if the document was bound to the paper binder in a paper state. . The document file stored in this way can be called from the table of contents page of an individual paper binder, and can be viewed one after another as if turning the document bound in the binder with a finger. By adopting such a user-friendly interface, for example, there is an effect that a participant of the video conference system can browse the document file shared through the emulator 130 without any trouble.

<Client system>
As described with respect to the overall system configuration, in the construction site management system of the present embodiment, the client system installed in the conference room 100A or the like in the same head office is connected to the head office server system 100 by the in-house intranet INT. Further, a branch client system 200, a field office client system 300, and an external organization client system 400 that are remote from the head office are connected via the Internet NW.

  In the present embodiment, it is assumed that the head office meeting room is equipped with a client system, assuming that, for example, a construction site and remote bases are connected in the head office to carry out a TV process meeting, etc., this is a server system. 100 and the company intranet INT.
