Description

Technical Field

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

[0002] At the construction site, safety management has become a key issue in the construction of construction projects. The construction site is complex and safety management is becoming increasingly difficult. Therefore, in such an environment, how to adopt safety supervision policies is particularly important. Adopting advanced management solutions to avoid accidents is critical to the advancement of the project. In the past, the traditional construction site had a very complex environment, inadequate supervision, and frequent accidents. According to data released by my country's Ministry of Housing and Urban-Rural Development, the number of safety accidents in my country's housing and municipal engineering projects has increased year by year in recent years, and the number of deaths in accidents has also shown an upward trend. The safety situation is very serious.

[0003] The construction safety monitoring system is a management system that monitors the overall construction process, and its purpose is to provide guarantees for the safety of construction workers. The sources of danger in the construction site mainly come from physical factors and behavioral factors. Physical factors refer to defects in construction equipment and protective equipment, and behavioral factors refer to abnormal working conditions of workers.

[0004] Since the traditional type of construction safety monitoring system is often a combination of simple environmental monitoring and construction results detection, it relies more on safety officer supervision for construction environment, safety items and other contents, which is prone to scattered construction management and improper safety project management, affecting the safety of the overall construction process and the perfection of detection work. Therefore, we propose a construction safety monitoring system and its monitoring method to solve the above problems. Summary of the invention
