    摘要： A buoyage for emergency communication and a corresponding rescue method are provided. The buoyage for emergency communication includes: a positioning device, a buoyancy block, a plurality of compression springs, an optical fiber, a reel, a frame, an optical fiber slip ring, a pure iron disk, an optical fiber connector and an oil-filled electromagnet, wherein the positioning device is fixed on a top portion of the buoyancy block, and is configured to emit a position signal of itself when the buoyage returns to a surface of water; the buoyancy block is provided above the frame, wherein the compression springs are provided between the buoyancy block and the frame; the pure iron disk is fixedly on a center of a bottom portion of the buoyancy block. The oil-filled electromagnet is adsorbed to the pure iron disk after being energized to limit a vertical displacement of the buoyancy block.
