The utility model discloses a kind of FA full convex fiber grinding devices, including base, a plurality of transversely arranged V grooves are set in the base;The front end of the base is recessed;A fiber is placed in each V groove;The upper cover plate is connected in the middle of the base, and the middle of the plurality of fibers is pressed;The front end of the base is connected with front cover plate, and the front end of the plurality of fibers is pressed.The upper cover plate is fixed in the middle of the upper end surface of the base by point FA head glue;Meanwhile, the middle of fiber and the inner wall of V groove are fixed by point FA head glue.The front cover plate is fixed above the recess by non-water soluble glue;Meanwhile, the front end of fiber and the inner wall of V groove are fixed by point non-water soluble glue.The utility model aims at overcoming the defects of the prior art and provides a kind of FA full convex fiber grinding device, and the yield of grinding is high, and there is no collapse.

This invention provides a low-power, ultra-long standby FPV drone image transmission system and its implementation method, comprising: an RF transceiver, a 1-to-2 RF switch, an RF front-end module, and a 1-to-4 RF switch; the signal output terminal of the RF transceiver is electrically connected to the signal input terminal of the 1-to-2 RF switch; the two signal output channels of the 1-to-2 RF switch are respectively electrically connected to the RF input pin of the RF front-end module and the signal input terminal of the 1-to-4 RF switch; the signal output terminal of the RF front-end module is electrically connected to another signal input terminal of the 1-to-4 RF switch; the output terminal of the 1-to-4 RF switch is connected to an antenna. In scenarios where takeoff is not in progress, this invention can shut down the RF amplifier (PA) in the RF front-end module, significantly reducing power consumption and fundamentally solving the heat dissipation problem. Therefore, the image transmission system can operate normally for extended periods without crashing, greatly improving the user experience.
