SML 2 Smart RFID Electronic Marker Locator
The SML 2 Smart RFID Electronic Marker Locator is a next-generation, advanced RFID underground marker detection system designed for the precise detection, identification, and documentation of buried infrastructure. Compatible with both standard analog markers and Komplex® RFID Smart Markers featuring unique ID codes, the SML 2 offers a powerful, user-friendly solution for permanent utility marking.
Engineered on an integrated, industrial-grade Android mobile computing platform with real-time cloud connectivity, the SML 2 enables seamless on-site acquisition of RFID marker locations with GPS coordinates (Based on its BUILT-IN GPS) at the time of installation, along with the immediate creation of GIS maps and databases—all during the installation process.
This fully automated solution eliminates the need for office-based programming or post-field data uploads, allowing for instant synchronization and field-ready deployment. Designed to support the accurate marking of underground utilities and simplify the process of navigating back to existing infrastructure, the SML 2 transforms traditional detection into a digitally empowered, efficient field solution—ideal for Operations & Maintenance of buried utility assets.
GNSS Compatibility: The SML2 is capable of being additional connectivity to an external GNSS RTK receiver for capturing coordinates with 2-5 cms accuracy.
What It Does:
The SML 2 Smart RFID Electronic Marker Locator is a handheld locator that helps field technicians, engineers, and utility professionals find and identify underground markers used for mapping and asset management. It not only detects markers, but also:
- Reads unique ID numbers from RFID Smart Markers
- Adds text and photo documentation to each marker
- Transfers data wirelessly to the Marker Database® software
- Records GPS coordinates and displays marker positions on Google Maps
How It Works:
- Detection & Identification:
Using its adjustable antenna bar, the SML 2 locates both traditional analog markers and Komplex® RFID Smart Markers. When a Smart Marker is detected, its ID is automatically read via RFID.
- Data Capture:
The inbuilt 2D scanner reads the RFID barcodes/QR codes for instantaneous RFID “ID” capture during installation, while the camera captures on-site photos. The operator can add notes or descriptions directly on the touchscreen interface. GPS coordinates of installed location is acquired resulting in Automatic GIS map creation.
- Data Management:
The device stores all marker data locally and can synchronize wirelessly with the Marker Database® software via Wi-Fi, Bluetooth®, or a SIM card. It also supports offline operation, syncing later when a connection is available allowing real time upload of data to cloud server.
- Visualization & Navigation:
Marker locations are automatically plotted using the built-in GPS and displayed in real-time via Google Maps integration, enabling efficient navigation and planning.
Applications of SML 2 Smart RFID Electronic Marker Locator
- Utility and Pipeline Mapping (Gas, Water, Electric, Telecom, Sewage): The SML 2 detects and identifies underground pipelines and cables using RFID Smart Markers. With GPS logging, camera documentation, and real-time data upload, it ensures every buried utility is traceable.
- Railway buried signalling & telecom asset mapping: In congested environments typical of railway yards & a long side tracks installing smart RFID markers allow mark and maintain specific cables – ensuring fast repair times & increasing safety. This is especially relevant when the smart RFID markers are installed with optical fiber cables.
- Construction Site Documentation: Marks and records the location of buried structures like conduits, drainage paths, or foundation anchors. The touch screen interface allows technicians to add photos and notes for each underground element.
- Environmental Monitoring: Tags and documents underground monitoring wells, sensors, or contaminated zones with RFID markers. SML 2 ensures accurate repositioning over time with GPS tracking and data capture.
- Underground Asset Tracking: Creates a complete digital map of all underground assets—utilities, control boxes, valves, or junctions. Marker data is stored, visualized on Google Maps, and synchronized with Marker Database® software.
- Smart City and IoT Infrastructure Support: Locates and documents smart infrastructure like fiber networks, IoT sensors, and buried automation devices. Combines RFID, barcode, GPS, and real-time connectivity for full traceability.
