Safe and reliable construction, unmanned labor-saving, 24-hour real-time monitoring.
This is a system that automatically measures the behavior of structures and slopes 24 hours a day and without human intervention 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 (warning value) is acquired, the accompanying alarm system will automatically detect it and send an email to the registered administrator or issue a warning through a display light. As of March 2024, the NETIS number has been updated! 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 and output of inclination displacement from two measurement points above and below The required inclination 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 open skies and for observing wide areas. 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 the understanding of surface movements from traditional point movements. The data is computed and processed into 3D coordinate values, enabling multi-faceted monitoring of the deformation of the measured objects.
