Recently, as the need for constant safety management increases due to collapse accidents caused by external displacement of buildings, it is necessary to manufacture a construction ground gradient meter and serial open information technology (IT) sensor that can be monitored wirelessly based on epoxy resins, polyvinyl chloride (PVC) pipes, and communication cables. In particular, waterproof performance is required for ground monitoring of underground spaces with water, and for this purpose, research was also conducted to double mold the inside of the incline system. Construction IT convergence's building slope measurement device technology can respond to safety accidents by checking the amount of change in building displacement through a real-time online monitoring system. In addition, it is an industry with various application markets by converging IT technology into the existing construction industry and can be used as a pre-quake detection monitoring system for structural collapse accidents caused by external displacement. Therefore, it is intended to secure a sustainable facility safety management system through research in the field of real-time measurement technology on various facilities and surrounding ground behavior.
