Sensing Principle
Detect activity through the ground—not through direct pipe contact.
The yellow monitoring unit is installed above ground. Its red high-sensitivity vibration sensor is buried in the surrounding soil near the monitored route or boundary. The sensor captures vibration and acoustic energy transmitted through the ground while the edge processor identifies application-specific events.
Important installation note: the buried sensor does not touch, clamp onto, or connect directly to the pipeline wall. For pigging applications, it detects the signal transmitted through the surrounding soil as the cleaning pig approaches, passes, and moves away.

Continuous low-power sensingThe MCU maintains continuous vibration acquisition with low power consumption.
02
Local edge classificationThe ARM and Linux platform analyze signal features and classify the configured event type.
03
Remote evidence and location4G, BeiDou/GPS, and dual cameras provide event location, imagery, and traceability.
Core Capabilities
A complete unattended monitoring node for remote field deployment.
Field sensing, edge intelligence, visual verification, communications, positioning, and independent power are integrated in one compact system.
MCU + ARM Architecture
Combines continuous low-power acquisition with Linux-based edge processing, classification, and local event management.
Dual-Camera Verification
Automatically captures site photos and video for intrusion and mining events, helping operators verify activity remotely.
Independent Solar Operation
A top-mounted solar panel and low-temperature lithium battery support unattended use in locations without utility power.
4G + BeiDou/GPS
Uploads event type, time, device status, imagery, and position to the monitoring platform or control center.
Harsh-Environment Design
IP65 protection and a -40°C to 70°C operating range support long-term deployment in remote outdoor environments.
Three Core Applications
One field platform, configured for three different operating objectives.
The same hardware architecture can be configured with different event models, deployment logic, alert rules, and evidence workflows.
APPLICATION 01
Oil & Gas Pipeline Right-of-Way Monitoring
Monitor selected high-risk sections along long-distance transmission pipelines. Detect excavators, breakers, drilling equipment, heavy vehicles, and unauthorized ground activity before buried assets are threatened.
APPLICATION 02
Pipeline Pig Passage Detection
Deploy monitoring nodes at selected checkpoints to record the characteristic signal as a cleaning pig approaches, passes, and moves away, providing passage-time and route-progress references for field teams.
APPLICATION 03
Illegal Mining & Boundary Encroachment Detection
Identify abnormal vibration from excavators, drilling rigs, breakers, and heavy vehicles around selected mine boundaries or protected resource areas, then activate remote visual verification.
Application boundary: HZ-PS-20A is positioned for long-distance oil and gas pipeline corridors, selected pigging checkpoints, mine boundaries, and protected resource areas. It is not positioned as a city gas distribution-network monitoring product.
Risk-Based Deployment
Node spacing follows risk—not a fixed dense interval.
Final quantity and spacing depend on the application, soil, burial depth, background vibration, terrain, communications, and required response time.
Remote, low-population corridors
Nodes can be several kilometers apart when deployed at selected control points or priority sections.
High-risk or populated locations
Spacing may be reduced to several hundred meters near road crossings, active construction, historical incident points, or pigging checkpoints.
Mine boundaries and protected zones
Nodes are placed around selected access routes, excavation-prone areas, and boundary sections based on site testing.
Monitoring Workflow
01
SenseThe buried sensor continuously captures ground-borne vibration and acoustic signals.
02
ClassifyEdge AI filters interference and identifies the configured event category.
03
VerifyFor excavation and mining events, dual cameras obtain site imagery for remote review.
04
Locate & UploadEvent time, node position, classification, status, photos, and video are uploaded over 4G.
05
Alert & TraceOperators confirm the event, dispatch personnel when required, and retain the complete event record.
Platform & Integration
Manage nodes, events, evidence, and location in one platform.
The monitoring platform centralizes multi-region field nodes and converts each valid signal into operational information for review and response.

FAQ
Technical and deployment questions.
Does the sensor need to touch the pipeline?
No. The red vibration sensor is buried in the surrounding soil near the underground pipeline. It does not touch, clamp onto, or connect directly to the pipe wall.
How does the system detect a cleaning pig?
The buried sensor records vibration and acoustic energy transmitted through the soil as the pig approaches, passes, and moves away from a selected monitoring point. Edge algorithms identify the characteristic passage signal and provide a time-and-location reference.
How far apart should monitoring nodes be installed?
There is no universal fixed interval. In remote, low-population areas, selected nodes may be several kilometers apart. At road crossings, construction zones, populated areas, pigging checkpoints, or other high-risk locations, spacing may be reduced to several hundred meters after site evaluation.
Can HZ-PS-20A be integrated with an existing control platform?
Yes. The system supports HTTP-based data exchange and can be integrated with a control center, SCADA environment, or project-specific third-party platform according to interface requirements.
