RealTrac Collision Awareness System (CAS) and Personnel Monitoring (RTLS) for Underground Mine
RealTrac Underground mining – is a multipurpose system for enhancing industrial security in underground mining.
The RealTrac solution Underground Mining enables to detect positioning of personnel and mining machinery; it provides the functionality for collision awareness system.
RealTrac Underground Mining - a multipurpose system for enhancing industrial security and overall efficiency of mining operation. The system consists of the following products:
Key benefits
360 ° monitoring around a vehicle
Detecting a distance to and direction of another object with accuracy up to 1 meter
Three control zones with ability to configure them as required
The system can operate independently and also be integrated into other systems
Short payback period
Operating principle and components
The system provides a situational awareness of the environment around a vehicle; detects presence of vehicles, personnel or objects within the pre-set zones. As soon as any object, vehicle or personnel equipped by RealTrac Collision Awareness tag enters the pre-set zones, the system emits tangible, audible and visual signals.
Alerts are emitted by:
Audible warning from machinery, activation of sirens or horns
Vibro signal from a tag
Blinking of a cap lamp
Vehicle lights blinking or activation of other visual signals
The intensity of alerts can be configured depending on the control zone.
Personnel equipment
Personal tag PROD TAG 410 is a mobile equipment enabling to detect positioning of personnel regarding a vehicle with installed VBUs of the RealTrac Collision Awareness system. The tag can be embedded into cap lamp or utilized as a portable equipment.
Personal tag PROD TAG 210 is a mobile equipment enabling to detect positioning of personnel regarding a vehicle with installed VBUs of the RealTrac Collision Awareness system.
Vehicle equipment
The Vehicle Operator Display (VOD) is installed in a vehicle cabin to provide a visual assessment of the environment around a vehicle and to receive notifications about dangerous proximity.
The Vehicle Control Unit (VCU) is installed on a vehicle and is calculating the distance from a tag to a Vehicle Beacon Unit (VBU) and the motion path of a tag. While detecting the control zone of a tag, it displays data about objects in a certain zone and activates the alerting system.
The Vehicle Beacon Unit (VBU) is installed on a vehicle in amount of 4-6-8 units depending on vehicle size and configuration and enables to detect personal tags (trackers) or VBUs installed on other machinery.
Independent operation
The system has embedded software and is completely independent from other systems and data networking. If a feedback channel is implemented, the system can transmit data about the detected cases of dangerous proximity, collisions and other relevant data to RealTrac server.
This enables to make further analysis of the incidents and to form activity reports.

Monitoring of personnel access levels
Due to geo zones with various access levels, an operator is always informed if the personnel are trespassing any forbidden zones or not. The reporting system enables to find out the access levels system violations and to prevent such incidents.
Personnel positioning monitoring in underground mine
An operator can receive data in real-time not only about the positioning of miners and vehicles, but also about the motion path of the monitored objects within certain period of time.
Control of work-time and time spent in a geofence
The RealTrac system enables to register the personnel entry and exit times from a certain geofence. This helps to monitor positioning of personnel in certain zones of a mine and to alert a miner about the need to get to the surface. The data about events is stored in server up to 10 years.
Personnel emergency notifications
In case of emergency, the system sends notifications about evacuation need to all miners. Also, the system enables to use additional warning devices like: sirens, alarm reporting etc.
Personnel detection and evacuation in cases of emergencies
The system provides a real-time control of the evacuation process, while displaying: time spent, personnel motion paths during the evacuation, and what is most important – the system enables to detect positioning of the personnel that couldn’t timely get to safe assembly points.
Key Benefits
Key benefits of the RealTrac Positioning for underground mining:
Enables to meet the legislative requirements and industrial security regulations in underground mining operation
Can use existing underground mine infrastructure
The hardware can be embedded into cap lamp and a miner doesn’t need additional equipment
The modularity of the system enables to add further functionality as required
Due to a single infrastructure, there is a possibility to upgrade a zonal positioning into precise positioning simply by adding additional anchors
Integration by means of the open protocol (API) enables to transmit the data to the HR recordkeeping system, computer-aided process control system etc
Operating principle and the system components
There are two directions of personnel positioning:
Zonal positioning
Detection of personnel or machinery positioning within the accuracy of the zone.
-
Accuracy: typically 20 meters
-
Detection range: up to 100 meters
-
Zone configuration: from 20 meters to *
*The zones are configurable upon Customer’s request. -
Installation expenses: low cost
Precise positioning
Detection of personnel or machinery positioning.
-
Accuracy: typically less than 1 meter
-
Detection range: up to 75 meters
-
Zone configuration: from 5 sq. m.
-
Installation expenses: medium-price
Equipment for personnel and machinery positioning in underground mine
