If the concrete placing height is high and the worker is pushed into one place at the time of placing, the working load may be exceeded and a collapse accident may occur. In order to solve this problem, in this research, we developed a monitoring load-measurement program based on a Bluetooth wireless load cell (load-cell sensor) so that the load can be converted to digital and the numerical value can be confirmed by the pressure sensor. The load cell using Bluetooth was designed and manufactured according to the support. Then, the performance was verified through 3D finite element analysis by modeling and experimental tests. In addition, we constructed a system to generate notifications and warnings step by step when the load is close to a dangerous load, confirmed the load distribution pattern by position, and established a method to confirm real-time data numerically and graphically. Finally, we evaluated the practical application of the load-monitoring system using field-test data using a wireless load-cell.<\/jats:p>","DOI":"10.3390\/s22103955","type":"journal-article","created":{"date-parts":[[2022,5,25]],"date-time":"2022-05-25T00:14:14Z","timestamp":1653437654000},"page":"3955","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Bluetooth Load-Cell-Based Support-Monitoring System for Safety Management at a Construction Site"],"prefix":"10.3390","volume":"22","author":[{"given":"Haksun","family":"Kim","sequence":"first","affiliation":[{"name":"Safety Inspection for Infrastructure Laboratory (SIIL), Advanced Institute of Convergence Technology (AICT), 145 Gwanggyo-ro, Yeongtong-gu, Suwon-si 16229, Gyeonggi-do, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sehwan","family":"Park","sequence":"additional","affiliation":[{"name":"Safety Inspection for Infrastructure Laboratory (SIIL), Advanced Institute of Convergence Technology (AICT), 145 Gwanggyo-ro, Yeongtong-gu, Suwon-si 16229, Gyeonggi-do, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minkyo","family":"Yeom","sequence":"additional","affiliation":[{"name":"Safety Inspection for Infrastructure Laboratory (SIIL), Advanced Institute of Convergence Technology (AICT), 145 Gwanggyo-ro, Yeongtong-gu, Suwon-si 16229, Gyeonggi-do, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hakbo","family":"Shim","sequence":"additional","affiliation":[{"name":"Research & Development Institute, LOTTE Engineering & Construction, 38, Naruteo-ro 10-gil, Seocho-gu, Seoul 06515, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soonjeon","family":"Park","sequence":"additional","affiliation":[{"name":"Research & Development Institute, LOTTE Engineering & Construction, 38, Naruteo-ro 10-gil, Seocho-gu, Seoul 06515, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6503-7950","authenticated-orcid":false,"given":"Junkyeong","family":"Kim","sequence":"additional","affiliation":[{"name":"Safety Inspection for Infrastructure Laboratory (SIIL), Advanced Institute of Convergence Technology (AICT), 145 Gwanggyo-ro, Yeongtong-gu, Suwon-si 16229, Gyeonggi-do, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,23]]},"reference":[{"key":"ref_1","unstructured":"(2021, March 09).
