OPERATIONS MANAGEMENT
Operators are using sensor data to optimise things such as driving routes and machine operations
Te key difference is that, while lidar scans in a 2D plane, radar emits its radio waves in a cone shape, which expands over distance. So, radar is less well suited to detecting small objects further away because of its longer wavelengths, especially at longer distances. Te RMS1000 performs exceptionally well, for example, to identify a human at 50m, but not so well for smaller objects. However, radar technology may scan a wider environment at longer ranges than an equivalent lidar scanner, but with less accuracy.
DRIVER ASSISTANCE For mobile machinery in mining environments, manoeuvring and reversing are the most frequent causes of accidents. Using sensing technologies to deliver data to a cab-based monitor gives the driver a view of areas that would not be otherwise visible. A good driver assistance system provides the driver with information without becoming distracting.
GUIDANCE AND COLLISION AWARENESS Many mines and quarries worldwide trust in Sick’s Minesic100 driver guidance and
awareness solutions to prevent collisions in dangerous areas. Tere are specially developed systems for excavator protection (EPS,) truck protection (TPS) and wheel loader protection (WPS), designed to gain the acceptance of operators and to avoid unnecessary distractions. Tese systems adopt behaviour
recognition, automatic warning zone adjustment and context switching according to different driving manoeuvres. For example, the Minesic100 EPS installations on large excavators monitor and detect their environment with an almost gap-free 2D lidar sensor, regardless of whether the objects are moving or not.
Te EPS’s advanced application
software uses the mounting position, excavator size, tail swing radius, safety margin, truck spotting radius and maximal loading area for detecting and processing object information, such as positions and size.
On the cab display, objects and
infrastructure are displayed as outlines. Te visualisation is simple and distances are visible without the need to interpret a camera picture.
SYSTEM MONITORING AND FEEDBACK Increasingly operators are harnessing sensor data through gateway systems to manage operations in real-time, analyse incidents and make maintenance decisions through cloud-based monitoring dashboards. Te Sick Monitoring Box uses a Sick telematic data collector (TDC) connected via Ethernet cable to the sensor. Te data is sent securely via LAN, WLAN, or mobile communications, so that a system can be monitored in real time from a smart phone or desktop. By analysing and comparing data and studying the statistical frequency of near-misses or costly stoppages, hazardous situations can be identified and prevented. Driving routes or machine operations can be optimised to ensure the most efficient operations. Data can also be input into digital maintenance software systems.
