Smart RFID Electronic Cable Marker & Marker Locator

Buried Cable Marker

The RFID electronic marking system uses digital technology to provide accurate location of buried infrastructure and site-specific data also known as underground utility marker, buried cable marker, pipe marker 

Smart Radio Frequency Identification System for permanent marking & tracing of underground utility assets & generation of maps of cable/pipe utilities being installed.

A Smart RFID Marker System contains 3 parts for creating a permanent record of WHERE utilities are buried.

Smart RFID Markers SM1500
Smart Marker locator SML (with Built in GPS)
Marker Database Software

The Smart Marker SM1500 is an electronic passive marker with built in RFID chip with a unique 10 digit hexadecimal ID number ensuring that every RFID marker buried with a cable or pipe is unique. It allows permanent marking of buried pipes or cables along its route or specific selected points under the ground.

Smart Marker SM1500 are buried “over” the buried utility or key facilities during construction or maintenance. The pre-programmed unique serial number of each Smart Marker SM1500 provides precise and clear marking of the route or each important point of the buried facility (joints, connections, change of direction etc.).

SML is a portable RFID smart marker locator with built in GPS designed for: 
a. Logging RFID 10 digit code, attributes & GPS locator of markers being installed. 
b. Fast localization & detection of buried markers.

Marker Database software is a unique software for database management of installed markers. It provides convenience to manage data about your buried facilities including display of installed maker locations on Google maps & easy access to marker attribute information (& therefore information of your utilities).

Smart Marker SM 1500 provides the most accurate method to precisely mark and locate your buried facilities such as:

  • Optical fiber telecom cables
  • Power cables
  • Gas Pipelines
  • CATV
  • Water pipelines
  • Sewage pipelines
  • Non drinkable water pipelines
  • Manholes
  • Buried Valves
  • Hazardous Area

When installed with your pipes or cables, the system will provide the following benefits:

  • Each marker is “Unique” with its own RF-ID 10 digit hexadecimal code.
  • “Lifetime marking” of Buried utilities with information about the utility.
  • Lifetime storage of data inside the Smart Marker - 50 years.
  • Creation of user text information for each Smart Marker Inbuilt GPS module inside each Smart Marker Locator allows GPS Coordinates of each RFID marker to be logged.
  • Acoustic GPS navigation (of buried markers) allows navigation back to “Specific” RFID markers.
  • Mapping of your Smart Markers in Google maps.
  • Detailed archiving & managing of data about your underground networks in unique Marker Database Software.
  • Archiving of the data in Cloud database. Share - later - if you require with partners.
Frequently Asked Questions (4 answered questions)
An electronic marker is based on resonance principle with a coil tuned to a frequency , defined based on international standard such as 101.4kHz (For telecom), 83.0 kHz (for Gas) etc. When an electronic marker locator is used at a corresponding frequency, the marker buried with a cable or pipe resonates and sends a signal back to the receiver confirming its presence making the utility locatable.
In case of an RFID Marker, a chip with a 10 digit unique hexadecimal code is embededed in the marker , making each marker one in a billion, uniquely identifiable. In addition, when used with a correponding RFID Marker locator, at the time of installation of marker which is buried with a cable or pipe, the marker locator also acquires the GPS coordinates of the marker and overlays on the RFID unique code to create a GIS of the markers installed, complete with attributes providing capability to the utility for network data to be available through database on PC or use with a mobile app .

Stop Before You Dig
The civic layout of India based on the growing need for housing and roads has changed beyond recognition.  As a result As-built maps of underground utility assets, if existing , have been rendered redundant and cannot be used for reference for presence of buried utility assets. Jcb Excavators or manual labour at work in the country are digging in the blind at most times, at the peril of significant safety concerns of digging directly into live high voltage cables. Such cuts of buried cables can lead to , in order of priority , fatality to the person excavating and serious losses to the company who has taken the work contract. Not to mention the relative inconvenience to the citizens. The underground space is a jungle of energised power cables, dead power cables, water pipes, jelly filled telephone cables and optical fiber cables. The detection of these assets is ...
