Pipeline monitoring and security systems

The monitoring technology captures various events in real time over long distances along the pipeline. The system, with connected fiber-optic cables acting as the sensing element, provides continuous collection and analysis of data on strain, temperature and vibration, building a complete digital picture of the facility's condition and forecasting possible deviations.

The system automatically classifies events and filters out false alarms.

System parameters

Cable type — standard fiber-optic cable or specialised
Detection of footsteps (3–5 m), vehicles (10–20 m), excavators (20–50 m), tracked machinery (40–80 m)
Monitoring of pipeline temperature changes
Tracking of pipe deformation and ground displacement (landslides, movements)

Advantages

Reduced UAV flight time — sorties only for detected intrusions
Reduced spending on the number of UAVs, cameras and radars
Reduced video surveillance costs by switching from fixed to PTZ cameras
Minimised probability of accidents
High event-location accuracy down to 1 metre, sensitivity 0.1 °C
Detection of small leaks from 1 cu. m and minor damage from 2 mm
The linear section requires no maintenance or electrical power and is explosion- and fire-safe

Perimeter security systems for extended facilities

The perimeter security alarm workstation is designed to alert the operator to unauthorised (or authorised — for tracking the fact and time of crossing the controlled zone) intrusion into the controlled area.

A distributed fiber-optic vibro-seismic sensor is used as the sensing element. As a result, the perimeter security alarm is electrically passive and does not react to high-frequency interference from radars and high-voltage lines.

During commissioning, the entire controlled perimeter is divided into zones depending on the terrain and type of fencing. Through the graphical interface, the workstation operator sees each zone linked to the map and the facility, and can arm and disarm zones. Colour indicates zone status: green — armed, grey — disarmed, red — alarm. When triggered, event information is stored in a log with time, location and status, and transmitted to the video surveillance system.

Workstation advantages

Continuous registration and control of intrusions into protected zones or specific sections
Division into logical security zones, management of zone status
Runs on Linux family operating systems (Astra Linux, Ubuntu)
Ability to generate reports on events and user actions
Role-based access model
Version with a mimic diagram and 3D facility plan

Monitoring and security systems for transport infrastructure facilities

Solutions for road and rail infrastructure. Geotechnical monitoring (GTM) is designed for the early detection of critical states of the subgrade under challenging geological conditions: permafrost soils, karst phenomena, landslide-prone sections, water-saturated soils (marshes, peatlands) and seismically active regions.

Primary purpose of the system

Early detection of permafrost degradation (thawing)
Identification of road sections with permafrost degradation
Measurement of vertical soil deformation, including during permafrost thaw
Determination of the vertical temperature distribution profile in permafrost
Assessment of the rate of permafrost degradation
Early detection of karst and suffusion processes
Determination of landslide boundaries along the road
Determination of the depth of the sliding boundary
Early detection of subsidence processes in water-saturated soils and seismically active regions

Monitored conditions

Permafrost soils
Karst phenomena
Landslide-prone sections
Water-saturated soils — marshes, peatlands
Seismically active regions
Generation of an alarm signal upon reaching critical values
Automatic transmission of a warning about the hazardous state of a section
