Figure 1: Actual example of telemetry data of a concrete pump truck at one runtime. Oil temperature is a typical continuous time series, which records the variation of oil temperature at one runtime of a concrete pump truck. Operation event sequence is a typical event sequence, which records the occurrences of six operation events (warm-up, landing leg unfolding, cantilever unfolding, concrete pumping, landing leg folding, and cantilever folding) on the concrete pump truck at one runtime.
