Abstract:

In order to further strengthen the safety and fine intelligent management level of Metro construction site, the author suggests that remote network system of safety risk in construction of Metro works should be established. The author analyzes the functional requirements of the system and points out that the system should achieve personnel, mechanical equipment, environmental monitoring and other information management functions, should realize evaluation of unsafe behavior and unsafe state, analysis on the risk of conflict, analysis of the special weather risk, forecasting and early warning, and identification and management of risks. Through analysis, the author believes that 3D GIS technology and spatial database technology should be used to develop the system. The author designs the overall structure of the system, and discusses the realization method of each function. Compared with existing visual monitoring system, the system has more expanded functions and is more intelligent, more integrated and more visualized. 
