At　present,　there　are　many　problems　in　the　process　of　the　construction　of　prefabricated　building.　For　example,　there　are　some　safety　management　issues　in　construction　hoisting　of　prefabricated　components,　such　as　rough　hoisting,　unprecise　control,　and　backward　on-site　treatment　methods　of　blind　hoisting.　Moreover,　the　traditional　the　construction　of　prefabricated　building　site　has　the　disadvantages　that　the　wireless　network　has　small　coverage　and　excessive　power　consumption,　and　the　information　upload　and　query　cannot　be　performed　in　real　time.　Aiming　at　solving　the　issues　in　the　construction　of　prefabricated　building　mentioned　above,　this　paper　proposes　an　intelligent　construction　control　method　for　prefabricated　building　based　on　LoRa　technology.　The　method　will　first　analyzes　the　LoRa　technical　characteristics　and　advantages　based　on　the　existing　Internet　of　Things　technology.　Secondly,　it　will　elaborate　the　specific　application　scheme　of　LoRa　technology　in　prefabricated　buildings.　Third,　the　precise　control　method　of　hoisting　of　precast　components　in　the　key　steps　of　the　construction　of　prefabricated　building　will　be　analyzed　in　detail.　Finally,　the　feasibility　of　the　proposed　intelligent　control　method　will　be　verified　by　the　case　analysis　of　a　prefabricated　building　project.　In　this　paper,　the　LoRa　technology　is　applied　to　prefabricated　buildings　through　research,　so　that　the　construction　site　can　be　managed　more　promptly　and　effectively,　and　the　quality　of　prefabricated　buildings　will　be　strengthened　to　reduce　construction　safety　risks.　It　will　provide　theoretical　reference　value　for　timely　and　accurate　intelligent　management　as　will　as　precise　control　of　prefabricated　components　during　the　construction　of　prefabricated　building.　It　is　of　great　significance　to　improve　the　overall　construction　management　level　of　the　prefabricated　construction,　thus　promoting　the　intelligentization　of　the　construction　of　prefabricated　building.　©　8th　International　Symposium　on　Project　Management,　ISPM　2020.　All　rights　reserved.
