Real-Time Recognition of Loading Cycles’ Process Based on Electric Mining Shovel Monitoring

Figure 3

Monitoring parameter curves and partitions in a loading cycle. (a) Waveform change of the swing angle; (b) waveform change of the swing power; (c) waveform change of the hoist power; (d) waveform change of the crowd power. The red, yellow, the blue, and green zones represent the digging, load swing, dump, and empty bucket return stages, respectively.
