Abstract: A platform through-beam sensor device includes a transmitter module and a receiver module. A light emitted by a light-emitting element of the transmitter module is shaped into a light pattern range by a transmitter mask. A range of the light received by a light-receiving element of the receiver module is changed to a receiving range by a receiver mask. When the present invention is used, the transmitter module and the receiver module are respectively installed on two ends of a mechanical apparatus that move relative to each other. After determining a safety range of the relative movement of the two ends, a state that the light-receiving element falls into the light pattern range and the light-emitting element falls into the receiving range is set to be within the safety range. Upon exceeding the safety range, a flying platform is controlled to stop, thereby improving the safety of the flying platform.
