Research On Track Monitoring System Of Prefabricated Building Components Based On Beidou High Precise Positioning

With the continuous development of prefabricated concrete buildings,the prefabrication rate and assembly rate of prefabricated concrete buildings are getting higher and higher,the scale of construction is getting larger and larger,and the types of prefabricated components are also increasing.On site,the entire process involves the exchange and alteration of PC components from multiple parties and types of information,and various types of information are complicated and messy.It is difficult to collect,analyze,and use this information in a timely manner.If the PC component exhibits information deviation at a certain stage,it will affect the construction stage.It will have an impact and is not conducive to the development of automated assembly.In the automated assembly process,it is not only necessary to collect the attribute information of prefabricated PC components,but also to master its real-time positioning information and establish a prefabricated PC component trajectory information monitoring system to efficiently feed back the positioning information of prefabricated components in real time.The effect of the whole process tracking,this subject mainly studies the method of establishing a prefabricated component track information monitoring system.First,install positioning sensors for the prefabricated components,determine the number and location of the prefabricated component positioning sensors based on the analysis of geometry and building mechanics,clarify the positioning method of the prefabricated components,and construct a prefabricated PC component positioning data acquisition system;The prefabricated PC component trajectory information monitoring system framework consists of a modular PC component database system,a prefabricated PC component positioning data acquisition system and a prefabricated PC component dynamic data monitoring system cloud platform.The dynamic data monitoring cloud platform combines Beidou high-precision positioning technology and advanced information management technology to carry out dynamic data monitoring of the storagetransport-storage management process of prefabricated components,the lifting and installation management process of prefabricated components,and the operation and maintenance management process of prefabricated components;Finally,it discusses the trajectory information monitoring process in the production and transportation phase of prefabricated PC components,the trajectory information monitoring process in the construction and assembly phase,and the trajectory information monitoring process in the operation and maintenance phase to guide the automated assembly of PC components.With the help of Beidou high-precision positioning technology,the trajectory information of the prefabricated PC components can be monitored,and the positioning information of the prefabricated components can be fed back in real time to obtain the location of the prefabricated components.It helps to realize the refined management of prefabricated PC component information,helps to improve the production and construction efficiency of prefabricated buildings,and helps to promote the standardized,automated,and intelligent assembly process of prefabricated buildings.
