Construction Height Fall Accident Monitoring And Warning System Development And Research

Since the reform and opening up,the construction industry has achieved vigorous development,is an important support for the development of national economy.At the same time,its extensive mode of operation and development,but also accompanied by a series of safety production accidents.Among them,the high fall accident rate is the highest,the most harmful.Due to the relatively backward construction safety management methods and technology application,it is difficult to carry out comprehensive monitoring and management of the construction site,and construction height fall accidents frequently occur.With the more and more application of the Internet of Things technology and BIM technology in the construction safety management,this paper puts forward the monitoring and early warning system of the fall accident of construction height.First of all,this paper analyzes the causes of 200 high fall accidents,determines the functional requirements of the system,system construction ideas,and completes the system framework design.Secondly,through research and comparison,the positioning method and positioning scheme suitable for the construction site are selected,BIM visualization software is selected,and the integration method of positioning technology and BIM technology is analyzed.Then,by identifying the unsafe environment in the construction environment,the unsafe area is divided into the borderline type and the hanging type,and different warning rules are designed,and different permissions and warning processes are endowed.Finally,according to the functional design of the system,the system is developed,and the monitoring and warning of height fall accident constructed is applied to a specific practical case.Through the specific application,the effect of the monitoring and warning system is verified.The monitoring and warning system for high-altitude falling accidents in construction constructed in this article basically achieves real-time dynamic monitoring and warning of high-altitude falling accidents,effectively avoiding the occurrence of high-altitude falling accidents and improving the level of construction safety management.
