Cable structure with information transmission and risk early warning functions and method of using same

A cable structure with information transmission and risk early warning functions, comprising:

• a power transmission unit and an optical fiber unit, wherein the optical fiber unit comprises a communicating optical fiber unit and a sensing optical fiber unit;
• the communicating optical fiber unit consists of a single-mode optical fiber and a casing for protecting the optical fiber;
• the sensing optical fiber unit consists of a single-mode optical fiber and/or a multimode optical fiber and a casing for protecting the optical fiber;
• the optical fiber unit comprises a plurality of optical fibers;
• the optical fiber in the communicating optical fiber unit and the optical fiber in the sensing optical fiber unit are packaged separately in separate casings or packaged together in a same casing;
• the optical fiber unit is placed between an outer sheath and an insulating layer of the power transmission unit;
• the optical fiber unit is arranged linearly along an axis of a cable;
• the optical fiber in the communicating optical fiber unit is configured for information transmission;
• and the optical fiber in the sensing optical fiber unit is configured for risk early warning on the cable and reduction of major safety accidents;
• wherein a bending radius of the optical fiber unit is not less than 30 times an outer diameter of a casing of the optical fiber unit, and the casing of the optical fiber unit is wound around a surface of the cable in an “8” shape.
