Safety of Drill Jumbos via Localization of Transponders

indurad uses a robust and multichannel localization technology (iRTT™ indurad Radio TransponderTag) for detecting persons and vehicles.
iRTT™ comes with a wide range of applications from collision avoidanceand positioning, via access monitoring and generally for productivity control.

How does it work?

indurad iRTT™ RadioTransponderTag is a modular solution that can be customized and extended to each clients’ specific requirements and site conditions:

Why is it an improvement?

iRTT™-was specifically designed for underground applications. Typical performance features are:

High Range Detection> 150 m untertage
Without visual contact

Up to 50m “round the corner” Detection of tagged objects and persons.

Typical Positioning Accuracy30 cm

Long battery life

Equipment 5 years, person tag 1 year

Operational Data Transmission

Transmission of battery status and other data (operating hours, tank level, etc.)  via radio-broadcast  / courier-communication

Scalability & Options

External display, external field antenna, above ground data server, operating data acquisition, etc.

More about our technology

iRTT-AU (Antenna Units) are first mounted on the drill rig. These antenna units then safely detect tags carried by nearby persons (operators, visitor etc) on helmets, belts etc. The crucial measurement is the distance between tagged persons to the carriage (lafette): once this falls beneath a defined threshold value, the iRTT™ device can be set to respond with appropriate measures (reduction of rotation speed, turn-off, etc.

Permanent tracking of all signed-up transponder in the environment
Examples of protection zones which can be configured requirement-related with indurad software

What else should be said about it?

The iRTT-technology is an innovative response to the new DIN EN 16228 “Protection against movable parts” norm. The iRTT™ is a “sensitive protection device” and therefore represents an efficient and practicable alternative to mechanical protection devices (e.g. protective grids). In particular for underground drill jumbos the use of mechanical barriers would seriously obstruct the working process, while some drilling positions would not be reachable anymore.
