[9] FIG. 2 is a block diagram showing an apparatus for monitoring a building status achieved during building a cavity frame according to an embodiment of the invention; and
[10] FIG. 3 is a diagram showing the configuration of an indoor global positioning system according to an embodiment of the invention. Best Mode for Carrying Out the Invention
[11] The present invention provides an apparatus for monitoring a building status achieved during building a cavity frame by a working robot, which includes a portable computer that remotely accesses a central host computer and downloads information on a work schedule; the central host computer that receives information on problems encountered during building a cavity frame from the portable computer; and an indoor global positioning system that remotely accesses the central host computer to transmit information on a position of the working robot in the cavity frame, wherein the central host computer transmits, to the working robot, an instruction to perform a corresponding work at the position of the working robot.
[12] An exemplary embodiment of the invention will now be described in detail with reference to the accompanying drawings.
[13] FIG. 2 is a block diagram showing an apparatus for monitoring a building status of a cavity frame according to an embodiment of the invention. As shown in FIG. 2, the apparatus for monitoring a building status achieved during building a cavity frame of a cargo according to an embodiment of the invention includes a portable computer 100, a central host computer 200, and an indoor global positioning system (hereinafter, referred to as "IGPS") 300.
[14] The portable computer 100 remotely accesses the central host computer 200 and downloads information on a work schedule therefrom. [15] The central host computer 200 receives information on problems encountered during works from the portable computer 100. At this time, the central host computer 200 transmits, to a working robot (not shown) disposed in the cavity frame of the cargo during building, an instruction to perform a corresponding work at a position of the working robot.
[16] The IGPS 300 remotely accesses the central host computer 200 and transmits the positional information of the working robot in the cavity frame.
[17] In the prior art, a worker needs to check the work schedule in detail in the cavity frame. In contrast, according to the embodiment of the invention, a worker can rapidly receive the information on the work schedule from the central host computer 200. Accordingly, the worker can achieve the position of the working robot in real time, and can rapidly meet the changing work conditions.
[18] FIG. 3 is a diagram showing the configuration of the IGPS according to an embodiment of the invention. As shown in FIG. 3, the IGPS includes a positional information input unit 310, a positional information selection unit 320, a positional information storage unit 330, and a positional information display unit 340. In addition, the positional information selection unit 320 includes a moving time condition de- terminator 321, a moving distance condition determinator 322, and a moving direction condition determinator 323.
[19] The positional information input unit 310 acquires the positional information of the working robot as similar as conventionally acquiring positional information thereof from a GPS (Global Positioning System) satellite (not shown). In this connection, a technology that calculates a relative three-dimensional coordinate of a specific location using an indoor GPS is disclosed in U.S. Patent No. 6,501,543, the disclosure of which is incorporated herein by reference.
[20] The positional information selection unit 320 determines whether or not to select the acquired positional information of the working robot on the basis of the determination results of the moving time condition determinator 321 to determine a condition on a moving time of the working robot, the moving distance condition determinator 322 to determine a condition on a moving distance of the working robot, and the moving direction condition determinator 323 to determine a condition on a moving direction of the working robot. If the positional information selection unit 320 determines to select the positional information, the selected positional information is output through the positional information display unit 340.
[21] The positional information storage unit 330 stores the positional information of the working robot selected by the positional information selection unit 320, for example, in a storage device, such as a database, in a file format.
[22] The positional information display unit 340 includes a display, and displays, on a screen of the display, the positional information of the working robot selected by the positional information selection unit 320, such that a worker can view the positional information of the working robot on the screen.
[23] The positional information selection unit 320, the positional information storage unit 330, and the positional information display unit 340 function independently and simultaneously. That is, when one unit is operating, other units are operating, specifically, three components are operating simultaneously. Therefore, it is possible to reduce a time required for acquiring the positional information of the working robot.
[24] Although the apparatus for monitoring a building status performed during building a cavity frame has been described in connection with the embodiment by way of the accompanying drawings, it should be noted that the embodiment is not limitative, but illustrative. It will be apparent to those skilled in the art that various modifications and changes can be made without departing from the scope of the invention.
