Claim 0:
1. An antenna system, comprising:
at least one antenna unit,
a control apparatus configured to control the at least one antenna unit to rotate, and
at least one limiting structure corresponding to each antenna unit, disposed on a rotation path of the antenna unit to calibrate a location of the antenna unit,
wherein:
the control apparatus is connected with the at least one antenna unit and an external control device, and configured to receive a rotation instruction from the external control device, and control the at least one antenna unit to rotate to a target angle according to the received rotation instruction,
any of the at least one limiting structure changes its state when a limiting event is detected; the limiting event at least comprises that, the at least one limiting structure touches a corresponding antenna unit, and a distance between the at least one limiting structure and the corresponding antenna unit satisfies a preset condition,
the at least one limiting structure is connected with the external control device so that the external control device, when detecting that any of the at least one limiting structure changes its state, determines a current location of the antenna unit corresponding to the limiting structure based on a location of the limiting structure whose state changes, generates a control instruction, and sends the control instruction to the control apparatus connected with the antenna unit corresponding to the limiting structure, wherein the control instruction is used to prevent the antenna unit from continuing rotating along an original rotation direction after the limiting event.
