<p>PURPOSE: A frame unit for a tank gunnery firing target frame is provided to determine whether a target is hit or not depending on the reception of a light signal, with a light emitting sensor and a light receiving sensor, which has an individual ID, being arranged by turns, and to transmit the determination by wire or wireless means in order to facilitate the checking of whether the target is hit or not. CONSTITUTION: A frame unit (10) for a tank gunnery firing target frame comprises a frame body, a light emitting sensor (30), a light receiving sensor (40) and a wired communications module. The frame body has a tube shape, which is empty inside, and multiple through-holes are formed on one side of the body with a fixed interval. Assembly holes are formed on both sides of the body so that a target frame is assembled. The light emitting and receiving sensors are arranged inside the frame body by turns to emit light and receive a light signal through the through-holes. The wired communications module receives a detection signal of the light receiving sensor and transmits the signal to an external relay terminal connected by a communications line.</p> |
