Tham khảo tài liệu 'deploying rfid challenges solutions and open issues part 8', kỹ thuật - công nghệ, cơ khí - chế tạo máy phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | Mine Planning Using RFID 197 Static information is the placement of shovel silos belts railway and inscriptions. Dynamic information is placement of trucks state of the shovel number of empty and loaded trucks utilization of the shovel time of the trip filling of the silos and load of the belts. At first static information must be constructed on a dispatcher s screen table 5 . Information Details Accuracy Scheme of the mine no required 10 m Places of loading no required 10 m Places of unloading no required 10 m Network of existing faces no required 10 m Network of abandoned faces no required 10 m Network of communications no required 10 m Transport network no required 10 m Placement of the stationary machines no required 10 m Various tables standard standard Various inscriptions standard standard Table 5. Static information for a dispatcher s screen Then dynamic information about current time output of the face current plan s execution pre-recognition of future accidents and support of operative decisions in case of accidents is presented on a screen in real-time mode table 6 . Information Regularity Reflection State of a face Every hour Color of a face Distribution of mobile objects Every 15 minutes Placement on the network Output of a face Every hour Current data Time of a working cycle Each working cycle Data Output of the part of the mine Each shift Data Fullness of every bin Every 15 minutes Full part of bin State of the transport machine Each trip Color of a machine Table 6. Dynamic information for visualization of current mining Information is changed on a dispatcher s screen by introduction of global variables by tags . Connection of medium sources with virtual reflection of mining is realized using OLE for Process Control OPC . The main rule for visualization is that the information must be enough to make a decision about improvement of current mining. For example a decision-maker can compare the activity in various places of the mine. Watching current .
