Train Patroller®
RAILWAY MANAGEMENT
DIGITAL TRACK INSPECTION
運転台のスマートフォン1台で、線路の状態をデジタルに記録する。
Train Patrol Support App Powered by Mobile Devices
Just mount a smartphone in the cab of a commercial train. Train vibration, forward camera footage, and positional data are captured in sync, digitizing train patrol work that previously relied on the visual checks and physical sensations of staff. Because it uses a general-purpose smartphone, deployment cost stays low.

PRODUCT OVERVIEW
計測から可視化、一元管理まで
A single smartphone installed in the cab captures train vibration and forward camera images. Measured data is visualized so track conditions can be reviewed at the desk and used to plan maintenance timing.
FEATURES
低コスト・高品質・使いやすさ。3つの価値で保線業務を支えます。
Low Cost
Because the measurement platform uses a commercial off-the-shelf smartphone, no expensive dedicated equipment is required. This enables low-cost train patrol support even for regional railway operators in challenging business conditions.
High Quality
Train vibration and position are measured with an accelerometer / gyroscope (100Hz) and GNSS (1Hz). "LABOCS®" assigns kilometrage with an accuracy of a few meters. Vertical vibration also correlates with the longitudinal level measured by track inspection cars, enabling consistent track condition assessment regardless of staff experience.
Ease of Use
With a suction-cup mount, setup on the cab windshield takes about three minutes before measurement begins. Choose from three modes — "vibration," "vibration & video," and "video" — to suit the purpose. Even when mounted at a tilt, the 3-axis accelerometer corrects readings to the vertical axis.
ANALYSIS
前方画像の解析と、列車動揺の計測
Forward image viewing and AI analysis
Supports forward image viewing and various anomaly detection via AI analysis. (*Some features under development)
Train vibration measurement
High-frequency train vibration measurement and tracking of track condition trends
MEASUREMENT
主な計測項目と計測モード
Choose from three measurement modes depending on the purpose. The smartphone's built-in sensors are used to capture train speed, train vibration, forward video and more in sync.
