PLANT DESIGN Video Analytics Even though the systems are high tech, the concept of video analytics is quite simple: the ability of the camera systems to analyze images in a defined context. Without these systems, the role is transferred to the plant operator or security personnel, who needs to analyze dozens of monitors and cameras in realtime, as well as identify erratic behavior involving people and assets. The idea behind video analytics is to bring intelligence to the camera systems to alert the operator if abnormal activity is occurring, based on pre-defined conditions and thresholds. Such technologies can be used simultaneously for process control monitoring, asset safety, and most importantly, personnel safety. Process Control/Advanced Supervision Systems The supervision system is an operator graphical interface/human machine interface that allows production and maintenance personnel to operate and oversee different mining operations and potential issues including: • System overview and parameters, • Real-time information processing, • Process trends, • Operation of systems, • Alarms and fault detection • Process control system and network status, • Process and production tuning, • Maintenance information and remote troubleshooting, and • Integration with camera systems. Theoretically, a fully automated process control operation can be achieved from a central control room. Advanced supervision systems encompass multiple redundancy characteristics that allow for safer visualization, as well as performance and interaction with mining control systems across multiple remote locations. However, the realtime characteristics of the major process areas, as well as potential safety issues and maintenance requirements still require a combination of decisions from the local mine control/supervision systems and remote monitoring and supervision. Advanced Weather Systems Severe weather can directly impact mining personnel safety, productivity and comfort.
