3 BASIC SYSTEM OPERATION
The CAS technology offers significant benefits in the safety and productivity of both
surface and underground mining operations by eliminating Heavy Vehicle blind spots using
a combination of high-resolution colour cameras and automatic object detection using
active Radio Frequency (RF) tagging of ‘AT RISK’ objects / personnel. Objects types that
can be fitted with RF tags include Heavy Vehicles, Light Vehicles, Stationary Objects,
Mobile Plant & Equipment and Personnel (currently under development). Object detection
zones ('safety bubbles') can be programmed from 0 - 80m range (long range option for
200 - 300m range). Heavy Vehicles fitted with camera only systems can be seamlessly
upgraded to include the RF tagging capability. The colour video display in the Heavy
Vehicle also functions as an alarm panel which automatically alerts the driver to the
presence of the type and number of objects detected in either the front or rear or side
detection zones. Cameras can be programmed to automatically switch to front or rear
cameras either on gear changes and / or automatic object detections. Heavy Vehicle
reversing sirens can also be switched off when Heavy Vehicles and other 'AT RISK'
objects / personnel are protected with the RF tags. The system also provides 2-way
alarming between the Heavy Vehicle and the ‘AT RISK’ objects / personnel, as any
hazardous situation involving two parties, in which one party does not the ability to action,
is inherently unsafe. Only objects tagged as Heavy Vehicles generate alarms as they
create the greatest risk of collision with other objects due to size and blind spots.
