Description

Technical Field

[0001] The present invention relates to the technical field of municipal engineering construction safety, and in particular to a municipal engineering construction safety control method and system. Background Art

[0002] Municipal engineering construction is an important part of urban construction, but due to its complex construction environment and diverse operation types, construction safety faces many challenges. In municipal engineering construction, accidents such as collapse, electric shock, and falling from height are common safety hazards. If they are not discovered and effectively controlled in time, they may cause casualties and property losses, seriously affecting the progress of the project and social stability. Therefore, it is of great significance to monitor the safety hazards of municipal engineering construction and carry out corresponding early warning control.

[0003] Traditional monitoring of safety hazards in municipal engineering construction often relies on manual inspections, that is, workers observe and record various safety indicators at the construction site, and take appropriate measures in a timely manner if abnormalities are found. However, this method is easily affected by human factors, such as the experience, responsibility and fatigue of the workers, resulting in inaccurate and incomplete monitoring results, and prone to omissions and misjudgments, resulting in safety hazards not being discovered and handled in a timely manner.

[0004] Traditional monitoring of safety hazards in municipal engineering construction usually only focuses on surface phenomena such as whether the construction personnel's operations are in compliance with regulations, which is prone to certain errors and is not conducive to timely warning of safety hazards. At the same time, it ignores the monitoring and analysis of the operating status of construction equipment, changes in the construction environment, and surrounding environmental conditions, resulting in the inability to timely discover potential safety hazards in municipal engineering construction, and thus it is difficult to implement effective prevention and control measures, resulting in safety accidents and causing huge losses to the smooth progress of municipal engineering.
