Detect

On the surface, operators in the cabs of large mining equipment often cannot see if another machine or vehicle is too close for safe operation. Detect helps alleviate this potential safety hazard and can also be configured to provide valuable information about site conditions and other assets working in the area. Underground, continuous equipment movement on a longwall face can pose risks to those in the working area.

Cat Detect — Object Detection

Command

Combining the Fleet, Terrain, Detect and Health capabilities of Cat® MineStar™ System, Command enables you to implement remote control, semi-autonomous or fully autonomous mining equipment systems - offering unprecedented improvements in operator safety, equipment availability and site productivity.

Health

Health records information on critical machine parameters fleet-wide. Data is available in real-time or historical database. Linked with on-board monitoring systems, Health provides wireless or wired transfer of this critical data to the service center for processing and review. Health may also be integrated into a production database for expanded analysis.

Fleet

Fleet is a fully integrated mine monitoring and management system that uses technology to improve productivity and maximize commodity value. Real-time interaction with mobile field equipment allows mine management to improve machine utilization, track material movement and monitor daily production against plan. Fleet is fully scalable to accommodate a growing fleet of machines or the need for additional capability and functionality.
