It is worth mentioning that obtaining a plurality of signal segments can satisfy the control requirement of the user. For example, in a first signal segment, the user wants to monitor the target to run at a greater speed, in a second signal segment, the user wants to monitor the target to run at a medium speed, and so on, with the speed getting smaller and smaller until stopped. The foregoing is by way of example only.
