Application Of UAV Technology In Construction Site Safety Evaluation

China's construction industry has developed rapidly,meanwhile,the condition of accidents on construction site is still at serve.In order to strengthen safety management,managers can use some new technology.At present,the Unmanned Aerial Vehicle(UAV)technology has been widely used in various fields.This paper will use it in construction site safety evaluation process,through the UAV's aerial function and intelligent management,it can complete a large area of patrol in a short time,and can quickly reach the area which people can not reach conveniently.Using the UAV can effectively improve the efficiency of security checks.This paper first introduces the research status of UAV in the field of construction,and summarizes the relevant theories and methods,including safety evaluation principle,accident causation theory,safety evaluation system,safety evaluation method and relevant technology of UAV on the evaluation of construction site safety.Secondly,through the way of questionnaire survey,on-site research and interview,determine the inspection content of UAV for the construction site safety evaluation.The contents of the inspection are then divided into different inspection areas.Combined with the Ministry of Construction over the years of safety accidents and statistics of large safety accidents,to determine the importance of the inspection area,that is,to determine the key detection area,sub-key detection area and the general monitoring area.Finally,design specific programs of UAV security inspection,including the regional check frequency,checking order,flight path and so on.After the completion of UAV in the construction site safety evaluation program design,select the specific project for application.Use the UAV for on-site security checks,to complete the data collection and safety evaluation.Combined with the results of safety evaluation,make the construction site of the project's safety management recommendations.Finally,the shortcomings of the research are summarized,and the future research is put forward.
