List of technologies related to safety
01Remote-operated optical-fiber node technology for early recovery from network failures
Is it wrong to seek 'non-dispatch operation' in optical fiber NW maintenance?

The spread of services using mobile lines and data centers (DCs) and the future spread of IOWN services requires the rapid isolation and restoration of faulty sections in the event of a large-scale disaster or failure. Our development promotes remote-operated optical-fiber node technology that constantly monitors lines from a remote location and instantly isolates the faulty section in the event of a line failure.

03Predicting the deterioration of road bridges using images
Visualize future equipment status with image recognition AI for proactive maintenance

This section introduces an AI that generates images of equipment to predict the progression of deterioration several years later from images taken of road bridges. This AI can predict the change over time of corrosion on steel parts of road bridges based on image data learned in advance and environmental information (temperature, precipitation, etc.) of the installation site and generate images showing the progression of corrosion. By utilizing this AI, the frequency of inspections, which are currently conducted at regular intervals, can be reviewed, repair plans can be optimized, and maintenance costs can be reduced.

04Bridge corrosion depth inspection system using drones and image recognition AI
By revealing the full extent of corrosion, bridge lifespan can be determined precisely at low cost

This section introduces an inspection system for road bridges that utilizes drones and AI, which was jointly tested by Kumagaya City and NTT Group. In this system, AI detects corrosion on steel materials from images taken by drones and estimates the depth of corrosion. This enables the system to calculate the bearing capacity of road bridges and optimize the timing of repairs, thereby reducing maintenance costs.

05Void detection technology for preventing road collapses
Let's explore the ground with the muons raining down on you

Road collapses, which have been gaining social attention, occur when the ground becomes unstable and voids form due to factors such as damage to aging underground pipelines or soil erosion caused by subway excavation work. Currently, ground cavity investigations are conducted from the surface to detect voids in advance. However, conventional underground radar surveys using electromagnetic waves are fundamentally incapable of probing deeper than approximately 2 meters. By establishing a measurement technology that utilizes cosmic rays (muons) that penetrate the ground, it becomes possible to investigate depths beyond 2 meters. We will introduce our current efforts and conduct a demonstration using the measurement equipment employed in our verification process.

07Laser removal of asbestos containing materials
Work automation prevents asbestos exposure

We introduce laser removal technology for asbestos containing materials. We succeeded in reducing working time by optimizing laser parameters.

08LiDAR for mechanization and safety improvement in laser cleaning
Laser Shuts Down When Object's Surface Not near Laser's Focal Point

When using high-power laser for rust removal, it is essential to avoid accidentally irradiating other objects or people. We will demonstrate that if the distance from the laser head to the target, measured with LiDAR, deviates from the preset range, the laser irradiation will be immediately halted to ensure safety.

We will exhibit a method of automatically generating work processes by integrating information such as operation logs and procedure manuals. This technology enables automation of work processes, including non-routine tasks, suggests improvements, and generates operation manuals automatically. In this exhibition, we will demonstrate how work processes can be generated for non-routine tasks, such as data processing, while interacting with systems and files, and how improvements to operations can be suggested.

In this article, we will introduce a visual image of road damage prediction.

09Non-stop inspection method for wind turbines using drones
Continuous wind turbine inspection to Increase power generation

Onshore and offshore wind power generation is drawing attention as one of the power sources that can increase domestic energy self-sufficiency.
The developed method aims to detect the presence of blade damage and motor abnormalities using drones without stopping the operation of wind turbines. With the this method, it will be possible to increase the amount of power generated by wind power and maintain it safely and efficiently.
There will be a static display of images and drones showing the demonstration experiment.

10Estimating cognitive state of workers to eliminate accidents
Understanding human cognition to ensure workplace safety

To eliminate workplace accidents caused by human error, it is necessary to prevent mistakes by determining the cognitive state of workers. We aim to tackle this challenge by estimating the cognitive state using eye movement (gaze and pupil). In this exhibition, we introduce an effective training system that can evaluate whether or not a dangerous area has been recognized, using eye movement information from commercially available devices, targeting a dangerous training scene in a VR environment.
