Description

  The present invention relates to a management system for drawings, documents, images, sounds and the like at a construction site.

  Conventionally, when managing the management and enforcement of materials necessary for buildings, the integrated information server installed at the construction site or site centralizes all the information generated at the site and all necessary information. To manage. In this case, by contracting with a provider or the like, an orderer, a design office, a cooperating company, and the like can also use the system through the Internet.

  The information managed by the above system includes work adjustment information, vehicle / lift schedule information, health and safety diary information, construction record photo information, entrance / exit management information, key management information, equipment order management information, construction status management By sharing this information with the parties involved, almost all of the site management information such as information, building process plan information, construction submission document information, construction report information, design change management information, design book information, etc., CALS / EC can be realized and productivity can be improved.

  In the case of such a management system, a visualization system through images is particularly effective. For example, in Japanese Patent Application Laid-Open No. 2004-78987 “Building Construction Status Confirmation Method”, the process of setting the shooting time according to the progress of the building and the shooting location of the building corresponding to each shooting time are set. The process, the process of generating the reference information for visual inspection of the building for each set shooting time and shooting location, and the process of shooting the actual shot image using the shooting device at the shooting location of the building site corresponding to the building The actual captured image and the visual reference information are displayed side by side on a display device, and the operator visually confirms the building based on the actual captured image and the visual reference information. A system including a process for confirming whether or not it is installed is shown.

In these systems, a construction supervisor can easily and quickly acquire inspection data for inspecting whether construction is being performed according to a design book without going to the construction site. (See Patent Document 1)
JP 2004-78987 A

  Furthermore, in these network systems, a video distribution server connected to the imaging device is provided on the local network, and JPEG still images and streaming video are received through the Internet network via this server, thereby preventing crime. It can also be applied as a remote video monitoring solution that uses a low-cost IP network to build a centralized monitoring system using live video that is being introduced in various facilities and places, such as early detection of disasters and disasters.

Problems to be solved by the invention

  However, in the case of the above-described inspection data acquisition system and general-purpose monitoring system, the independence of each imaging point as information is high, and the relevance between each piece of information is lacking. More specifically, video images from surveillance cameras used for on-site management, audio from loudspeakers, on-site meeting records (drawings / documents / videos / sounds), basic design documents for buildings (drawings / specifications) The space and time elements for the document / construction plan) were not linked, causing problems such as time-consuming tasks for grasping and organizing information.

Means for solving the problem

  In view of the above-described problems, the present invention is a management system that comprehensively monitors a construction site and a management site. The management system includes a monitoring device provided at each monitoring point of the building site, and a network for each monitoring device. The image data obtained at the monitoring point and the spatial data analyzed from the image data are displayed in real time in association with time axis data and environmental data, and are recorded and stored. It is characterized by doing.

  Spatial data includes at least management data such as design drawings of buildings to be monitored, and can be displayed or analyzed in association with spatial data that is on-site data. Environmental data, temperature, humidity, wind power, rainfall It is characterized by being able to display or analyze in association with spatial data that is on-site data, including meteorological data from sensors.

  A device in which the monitoring device can be fixed or dynamically moved is applied.

  FIG. 1 is a schematic diagram showing a first embodiment of the management system of the present invention, and FIG. 2 is a schematic diagram showing a second embodiment of the management system of the present invention.

  In view of the above problems, the present invention is to construct a system that displays all data in real time in association with 3D position data and time axis data in the field space, and records and saves them on a large-capacity server. is there.

  As shown in FIG. 1, drawing data, document data, video data / audio of cameras and robots for each property are stored in a large-capacity data management server S1 installed in a related facility connected to the head office 12 of the construction company or a local network. Data is collected via the Internet NW or the private network NW.

  More specifically, these field data are composed of spatial data a, time axis data b, and environmental data c.

  The management server can display all the above drawing data, document data, video data and audio data of cameras and robots in real time with a projector or the like installed in a management room or a meeting room in the head office 12 and simultaneously display the data. Record and save on the server.

  At this time, the CAD drawing data classifies the three-dimensional position data and graphic data for each room on the site from the street core / floor height, and the video / audio data is managed on the time axis. Record and save in association with. In other words, time and space are linked organically. Therefore, at the construction site, this information is associated with the site construction drawing, and a system that can be grasped in real time, for example, on the screen of the site management office, and that can store and refer to this information is constructed.

  The design / construction drawings are identified by the floor height of the building, the plan view, and the elevation view, and the construction state is made into a drawing.

  The position information can be stored in the data server as digital data by extracting the text data from the CAD data, for example, by extracting the text data from the CAD data and the three-dimensional position by the floor height, the center of the plan view, and the elevation view.

  Data such as the progress of daily work at the construction site, meetings, and recorded photographs are projected onto the screen together with the drawing position data in real time, and simultaneously associated with the time axis and stored in the data server as time axis information.

  As the types of information, for spatial data a, there are still image data and moving image data of fixed point / timed shooting by a fixed point camera, temporary still image data and moving image data of temporary shooting by remote operation of the camera.

  For the time axis data b, it is preferable to include not only a time controller but also a scheduler for progress management.

  For environmental data c, on-site photo data using on-site PHS and digital cameras at the time of the site manager or at the time of sudden occurrence, voice data of field report telephone, temperature, humidity, wind power, rainfall, etc. installed at the site Weather data is taken into account, thereby making it possible to create a plan, for example by correcting a standard schedule in fine weather.

  In the management system configured as described above, the management server S1 can be installed as a temporary system in the office of the construction site as in the second embodiment shown in FIG. This is because the time axis data b can be held even when a failure occurs in a public network such as the Internet.

  In the present invention, real-time display is possible not only at the head office 12 of the construction company but also at related facilities 13.14 such as sales offices via the network. Screen-type functional glass composed of a plurality of large glass plates such as laminated glass can be used. In such a system, a drawing is displayed on a large screen at a field office, a drawing change instruction and examination items are entered on the screen with a marker, and the contents are recorded and stored as image data. Can be wasted. In addition, the meeting time can be shortened and the cost can be reduced. In addition, by installing the microphone and recording the contents of the meeting, it is possible to prevent leakage even when creating the minutes, which saves time and effort for making the minutes.

  For data efficiency, the primary data recorded and stored on the server is thumbnailed into data with a small file size using commercially available high-compression software, thereby improving the efficiency of data transfer and browsing with a browser. It is preferable to save money and save money.

As a result, it is possible to quickly find the information necessary for converting the image into thumbnails, and after the building is completed, important data is saved as it is, and historical data is saved as a small amount of data. Thus, the server capacity can be reduced, and a temporary server can be installed as described above.

The invention's effect

  Since the present invention is configured as described above, a CAD drawing can be projected onto the MGSS at the meeting in the field, and the written character data can be stored and printed. Can be projected and recorded on the MGSS of the office, the site office, the head office, the design and the owner can grasp the real-time construction status and the crime prevention management as necessary, check the schedule table and perform the construction schedule management and material management, etc. Benefits. Further, it is possible to construct a clear and visible system by effectively using an existing system, and to make it easy to make reference to stored data without error.

  Whether these image / sound data are proceeding according to the meeting by referring to the data at a later date by recording / storing in relation to which part of the meeting the meeting or the 3D position data of the meeting drawing The progress can be confirmed, and by classifying it by the three-dimensional position data and the four-dimensional data on the time axis, the passage of time can be confirmed by referring to a specific place on the site.

  On the other hand, security data can be secured by referring to stored data by combining management ranges so that not only managers but also necessary contractors can be referred to.

  The effects at each facility are as follows.

  <Management and monitoring at the field office> (1) A monitoring room where outside people cannot enter is set up in the field office, and a large screen is used to display the video stream of the monitoring camera and microphone installed in the field, and the sound is played through the speakers. While constantly monitoring, the camera is remotely operated and enlarged to check the dangers of suspicious people and field work. Even at this time, you can check the drawing and meeting details of the place on the sub-screen for a thorough check. (2) By monitoring the suspicious person and dangerous work through a microphone, the supervisor can reduce the number of patrols and reduce costs. (3) In the case of an accident such as an accident, it is possible to give instructions while grasping the entire site, so there is no redundant treatment, and recurrence can be prevented, resulting in cost reduction.

<On-site management and monitoring> (1) Although the above-mentioned management reduces the number of periodic patrols, the need for on-site patrols remains. On-site patrols are equipped with handy cameras, handy decoders, portable IP phones, hands-free microphones, etc., and send real-time video and audio data to the site office via wireless LAN. You can receive instructions, report to the field office, and have a meeting. (2) The video and audio data are also recorded and stored as 4D data of 3D data and time axis data on the drawing from the position at the time of reporting. (3) On-site construction records can be recorded and stored as photographic data by extracting the frame capture screen from high-precision handy camera video data.
