Notice of participation in the "Hokkaido Civil Engineering and Architecture Future Technology Exhibition 2025" from July 2 (Wednesday) to July 3 (Thursday), 2025.

For tunnel construction and night work! Displaying highly visible virtual signs to contribute to safety management.

The Virtual Sign is a system that projects pre-set signs from a high-brightness light source mounted on the main device, by setting the signs in advance on the cloud at the site office or similar locations. By brightly and clearly projecting signs at tunnel construction sites or nighttime construction sites, it effectively informs site workers of restrictions and raises awareness. Various sign contents for use at construction sites are prepared, and the display content can be changed remotely via the cloud, reducing the hassle of installing or replacing signs and leading to labor savings. The main device is equipped with a communication terminal, and the connection to the cloud can be selected from LTE, wired LAN, or Wi-Fi. It is also possible to project sensor information and surveillance camera footage installed at the communication site via the cloud. Additionally, it has dustproof performance that allows it to be used without impact in tunnel construction, as well as waterproof performance for use in rainy weather. By projecting images from a high-brightness light source, it is possible to create large and clear sign displays, similar to projection mapping, by installing the device in locations that do not obstruct vehicle traffic.

Reduce working hours by approximately 50-70%! Significant improvements in productivity and work efficiency with AR rebar inspection that can be conducted by one person.

【NETIS Registration Number】CB-230022-VE 'BAIAS' is an AR system for rebar inspection of reinforced concrete structures that allows a single person to easily conduct inspections using a tablet. By automatically measuring the number, diameter (thickness), and spacing of rebar from images taken with a tablet, it significantly reduces the time and effort required for inspections. This system enables what was traditionally a multi-person task of inspecting rebar in reinforced concrete structures to be performed easily by one person, contributing to labor-saving and efficiency on site. 【Features】 ■ Measurement of rebar spacing is possible even with double rebar ■ Supports measurement of cover thickness ■ Contributes to labor-saving in the inspection process with the electronic blackboard function ■ Reduces preparation and work effort with the two-point measurement function *For more details, please refer to the PDF document or feel free to contact us. *This product is for the domestic market.

You can check measurement data from a remote location! Automatically calculates the temperature difference between the surface and the center of the concrete.

【NETIS Registration Number】KT-230101-A The "Ondroid Temperature and Humidity Measurement System" allows for the setting of alert values for each measurement location. When the measurement data exceeds the alert values, the responsible person can be notified via email. It automatically calculates the temperature difference between the surface and the center of the concrete, which can be a factor in temperature cracking, and when the temperature or humidity at specific locations exceeds the alert values, it can automatically activate the irrigation pump or jet heater, leading to increased productivity through labor-saving measures. Please feel free to contact us if you have any requests. 【Features】 ■ Data differential monitoring function ■ Temperature difference monitoring function ■ Linkage with irrigation pumps and jet heaters *For more details, please refer to the PDF document or feel free to contact us.
