COLLISION AVOIDANCE
informed decisions about how to select and use these technologies . They are not researchers or professional ‘ testers .’ What we ’ ve done is try to provide knowledge and information , facts and data , and an ‘ instruction manual ’ of sorts to help them through the assessment process . An added benefit of what we ’ ve been developing is that the suppliers / developers of these technologies benefit by understanding how the system can / will be used and how they themselves should be validating / testing their systems .”
All of this work is the culmination of almost five years of research and testing by Mining3 under the funding & auspices of ACARP and with funding & support from EMESRT . Mining3 says it has brought intellectual power to the table internally but has also collaborated and engaged with CSIRO , the University of Pretoria , and the University of Queensland Australia for substantive contributions . The project will finish in the next few months and there will be a dedicated website through Mining3 where all of the information will be made available to the industry .
While Mining3 is not developing independent CAS or PDS it is worth remembering that it did do the R & D on its own system called AcuMine back around 2005 . It was a joint R & D series of projects with University of Sydney and it was a true peer to peer collision avoidance and awareness system – a SMART system . It was state of the art but the industry wasn ’ t ready to take it on-board seriously at the time and it hasn ’ t been brought back to the table due to IP and legal complexities plus today many OEMs and suppliers
EMESRT VI Control Classification Level Definitions 7 to 9
Level 7 – Operator Awareness Technologies that provide information to enhance the operator ability to observe and understand potential hazards in the vicinity of the equipment n Ability to provide enhanced situational awareness n Alerts the operator to a potential abnormal situation n Provides context of the situation to the operator : Where is it ? What is it ? How far away is it ? What is its heading ? How fast is it going ? n Supports visual confirmation for the operator
Level 8 – Advisory Controls Technologies that provide alarms and / or instruction to enhance the operator ability to predict a potential unsafe interaction and the corrective action required
• Determines an imminent threat of collision
• Provides a specific instruction to the operator to intervene ( act )
• Operator assesses the instruction in relation to other contributing factors then intervenes ( acts )
Level 9 – Intervention Controls Technologies that automatically intervene and take some form of equipment control to prevent or mitigate an unsafe interaction n Provides a specific instruction to the Machine to intervene ( act ) n Machine assesses the instruction in relation to other contributing factors then intervenes ( acts ) n Relinquish intervention control to the operator should they take evasive action n Provides a manual over-ride to recover after a collision intervention scenario has occurred
are developing these systems commercially anyway . complex , dynamic PUEs ( potentially unwanted Grandone said that one of the significant findings events ) that are the most commonly occurring near of testing so far is that it cannot successfully and misses or incidents in the surface mining industry and safely test CAS or PDS relative to any of the more so cannot field test Level 9 controls for the same .
