Description

Technical Field [0001] The present invention relates to a real-time building site monitoring system for monitoring the progress of a construction site, and a real-time construction site monitoring method for monitoring the progress of a building site using the real-

The present invention relates to a method for checking the progress of a building at a remote location by photographing and transmitting the progress of a building site with a camera. Since the construction site is wide in size according to the site, it can not monitor the construction history or monitor the behavior of the workers at all times. Therefore, through the multiple cameras attached to the smart terminals held by a large number of workers, Etc. in real time in the remote office or headquarters.

The prior art related to the present invention is disclosed in Korean Patent Registration No. 10-0526621 (published on November 8, 2005). 1 is a flowchart of the conventional remote welding monitoring method. 1, in the conventional remote welding monitoring method, when the welding data is transmitted from the remote monitoring means 100 (S10), the main transmitting and receiving unit 212 of the main monitoring means 200 receives the working data (S20) The control unit 230 determines whether the job has started according to the received information (S30). If it is determined in step S30 that the job has been started, the control unit 230 stores the job data in the job data storage unit 260 (S40). In addition, the control unit 230 displays the work data stored in the work data storage unit 260 on the display unit 242 in real time (S50). At this time, the manager can determine the welding quality by viewing the visual data displayed on the display unit 242. The control unit 242 determines whether welding has been completed according to the information continuously received (S60). If it is determined in step S60 that the welding has not been completed, the controller 230 performs the steps S40 and S50. If it is determined in step S60 that welding is completed, the controller 230 analyzes the job data stored in the job data storage unit 260 (S70). For analysis of the work data, the control unit 230 determines the welding failure based on the welding time from the start of welding to the completion of welding, the consumption current, etc., according to the work data stored in the work data storage unit 260. When the analysis of the work data is completed in step S70, the controller 230 determines whether there is a welding defect (S80). If it is determined in step S80 that there is a welding defect, the control unit 230 alerts the remote monitoring unit 100 of the welding defect (S81). Accordingly, the alarm unit 140 of the remote monitoring means 100 warns the operator of the welding failure, and the control unit 230 completes the work (S90) and returns.

The conventional technique as described above can accurately grasp the welding state of the welding part, but can not grasp the entire working state periodically or in real time. Accordingly, an object of the present invention is to provide location information and construction status information in real time through a smart terminal of a worker possessed by a plurality of workers for high-quality construction in a construction or civil engineering worksite.
