COLLISION AVOIDANCE JULY 2018 • E&MJ 41 tor receives an alert from the CAS, they can trust that the alert is legitimate, and since the alert transmission is near-in- stantaneous, they have time to take cor- rective action to prevent collision." Dunsch described DSRC platform- based communications as the "fastest pos- sible," enabling CAS "to transmit immedi- ate alerts within milliseconds of the sys- tem's detection of a potential collision risk, increasing operators' situational awareness and empowering them to take corrective action to prevent an impending collision." By leveraging the DSRC platform, CAS has proven reliability. DSRC communica- tions are "immune to such environmen- tal effects as high dust, mud, snow, rain and fog," Dunsch said. "This makes the DSRC technology especially effective in open-pit coal mines, which tend to have many low-visibility areas, as well as mines located in challenging climates." And be- cause the DSCR platform operates on a dedicated channel, "the message trans- mission will not be affected by other wire- less technology signals," he said. DSRC tech is being adopted by many of the major automobile manufacturers that sell to the public and will be built into future vehicle models. When one enters the mine site, it would receive pertinent actionable data, Dunsch said. "Since the DSRC capability is already built in to these visiting vehicles, they will be detected by all CAS-equipped ve- hicles on site, without an operator's need to turn the technology on or off," he said. "The lighter, visiting vehicle may also re- ceive its own notifications, since it will be equipped with the same DSRC technology that the mine site's large vehicles use." CAS works best in large, open-pit op- erations. "Cluttered environments with high walls and deep pits might reduce the effective range, but DSRC is intended for use in urban environments and was designed to perform even in challenging mining environments," Dunsch said. "As is true for all radio waves, an open, unob- structed plane tends to provide the best setting and longest communication range for the DSRC technology." Pre-existing infrastructure require- ments for deploying CAS are minimal. It "does not require any communications infrastructure to transmit alerts to opera- tors," Dunsch said. "However, to integrate the CAS with Modular's DISPATCH FMS for assessment or reporting purposes, a separate high-bandwidth wireless network is required." Integrating CAS with FMS enables the former to route data that trig- gers notifications about non-typical events in DISPATCH, and to alert the mine con- troller or dispatcher as needed, he said. "Modular does also recommend, and use, network infrastructure for support, health monitoring and firmware updates." CAS can operate as a stand-alone system and as a stepping stone toward the eventual adoption of Modular's FMS. Its simplicity and dependability make it an optimal entry point, Dunsch said. "The peer-to-peer approach em- ployed by DSRC provides the capabil- ity to effectively improve operators' situational awareness facilitating the safety-improving capability that mines need without requiring a wireless data network or other communications infrastructure."
