Slope Warning System
A disaster-prevention system that measures slope displacement in real time
at locations with ground-collapse risks—such as road cuttings, steep slopes,
and urban retaining walls—and provides early warnings of hazardous situations.
- Underground embedded measurement sensors
- LoRa / LTE wireless communication
- Real-time alerts and control-room integration
What is the Slope Warning System?
This disaster-prevention system detects collapse risks in areas closely connected
to daily life—such as road cuttings, retaining walls, and embankments in urban
residential zones—where failures are especially likely during thawing periods
or the rainy season.
The system consists of wireless slope-measurement sensor terminals/nodes and a
Remote Radio Gateway (RRG: Remote Radio Gateway with built-in control functions
and communication modem), along with solar power units. All components are
centrally monitored and managed through the supervising authority’s server system.
-
NormalWhen no abnormalities are detected on the
slope Status is displayed every hour -
CautionImpact or tilt between 5–10° compared to
reference values Inspection required -
WarningTilt exceeding 10°
Warning triggered
System Configuration
Data measured by sensor nodes is transmitted in real time to the control-room server via wireless communication devices (terminals/gateways) using LTE or LoRa networks.

Worksite Intrusion Alert System
A safety system that detects unauthorized vehicle intrusion in real time
at active worksites such as highways, local roads, and railways,
immediately issues alerts and secures evacuation time for workers.
- Real-time detection of hazardous situations
- Instant alerts to workers and managers
- Integration with on-site safety management systems
What is the Worksite Intrusion Alert System?
Despite strengthened safety facilities during road closures or maintenance work,
on-site safety accidents continue to occur. This system applies advanced technology
to establish a real-time hazard information management system that effectively
responds to worksite safety incidents.
When an unauthorized vehicle intrudes into a work zone, detection devices transmit
hazard information wirelessly and trigger alarms, securing critical evacuation time
for workers and helping prevent serious accidents.
The system has received positive responses not only from the Korea Expressway
Corporation, but also from local road construction companies, railway authorities,
and other organizations requiring enhanced safety management.
-
When an unexpected situation occurs
at the worksite, the sensor is activated -
When the flagger detects danger and presses the button,
warning lights and sirens are activated on the receiver -
Audible alarms and visual signals enable recognition
of the situation and prompt worker evacuation
Signal Baton Sensor
The signal baton sensor can be attached to standard roadwork rubber cones and will not detach due to external force.
- Confirms that alarms and warning lights on the portable receiver are activated upon impact
- Confirms activation within 0.5 seconds after impact
Portable Receiver
The portable receiver is mobile and operates sirens and warning lights in compliance with applicable standards.
- Supports power On/Off operation
- Battery charging status is displayed on the monitoring screen
- Alarm signals are activated within 0.5 seconds upon baton impact
- Alarm sound and warning light output are strong enough to be clearly recognized on highways, based on predefined test standards
- Mobile design with wheels allows easy relocation
