A detection unit detects a moving path of the approaching object; a storage unit stores a warning information including the warning area and the confirmation condition; and a processing unit receives the detection signal provided by the detection unit to acquire the current moving path of the approaching object. When the approaching object is detected as moving in the buffering zone, the confirmation operation of the confirmation condition is activated. When the moving path falls in the warning area and fulfills the confirmation condition, the processing unit sends out a warning signal. Therefore, a potentially dangerous approaching object is accurately identified, and the warning is correctly sent.
