Abstract: The present disclosure relates to a work safety management system using a safety belt unit for high-place work, and safety during working at a high place can be enhanced by determining whether a worker has fastened a seat belt to a safety structure, and the location of the worker, whether the seat belt is fastened and whether the work is on progress can be monitored in real time from a remote location to prevent safety accidents.

Abstract: Provided is a fire detection method and system, which includes: a video monitoring step of performing real-time video monitoring on a set surveillance space and/or surveillance area; a fire detection step of detecting a fire sign on the basis of analysis of video data; a control step of supporting a control person using a display means to make a decision on whether or not a fire has occurred; a control supplement step of supporting a control supplement function for improving accuracy of the decision-making; a remote control supplement step of supplementing the decision-making on whether or not a fire has occurred by way of remote support in a situation where there is no response from a control person within a set time; and a fire notification step of performing fire notification and warning in a surveillance space and/or a surveillance area where occurrence of fire has been confirmed.

Abstract: The present invention relates to a multi-dimensional risk matrix and a method of generating the same, which can support to associate comprehensive risk determination, evaluation, and follow-up supports from the aspect of activity, environment, and worker on the basis of past statistical data, calculate an actual risk of a corresponding activity by independently analyzing and calculating risks of activity, environment, and worker that may have a major influence on a construction work, increase practical utilization by reflecting actual evaluation of a manager, and reflect special factors to additionally review individual factors that can be ignored in statistically analyzed general factors.

Abstract: Disclosed is a safety management system for a worker at a tunnel construction site, the system comprising: a server for controlling the safety management system; routers installed at predetermined intervals at the tunnel construction site; a worker terminal carried by the worker; and at least one information collecting terminal for receiving worker information from the worker terminal and collecting environment information of the tunnel construction site so as to transfer the same to the server, wherein the server determines a location of the worker by using the worker information; divides a map of the tunnel construction site into a plurality of zones and displays the same on a browser; displays the worker information on a zone where the worker is located, among the plurality of zones; and determines at least one danger zone on the basis of the environment information and previously input risk factors.
