Safe and reliable construction, unmanned labor-saving, 24-hour real-time observation.
This is a system that automatically measures the behavior of structures and slopes 24 hours a day and unmanned, using automatic targeting total stations and GNSS as sensors. By immediately processing the acquired data, it is possible to view three-dimensional displacement information on a PC monitor or remotely via the internet. If data exceeding the pre-set displacement management value (alert value) in the system is acquired, the accompanying alarm system will automatically detect it and send a warning to the registered administrator via email or display lights. The NETIS number has been updated as of March 2024! KT-230145-A (Three-Dimensional Displacement Automatic Measurement Cloud Management System)

basic information
● High-precision 3D displacement measurement is achieved Measurements are conducted using an automatic total station with a distance measurement accuracy of 1mm and an angle measurement accuracy of 1 second. ● Calculation output of tilt displacement from two measurement points above and below The required tilt angle values due to changes in bridge piers, etc., are output by calculating the coordinate values of prisms arranged above and below. ● Advantages of using GNSS It is suitable for sites with an open sky and for observing a wide area. Measurements using GNSS are not affected by weather conditions such as fog, rain, or snow. ● Screen interface and reports Not only does it numerically display the behavior of the monitored area, but it also provides "plan vector arrow display," "cross-section subsidence arrow display," and visually displays the current measurement points within the site plan. This allows for understanding of surface movements rather than just point movements. The data is calculated and processed into 3D coordinate values, enabling multi-faceted monitoring of the deformation of the measured objects.
