The application discloses an underground intelligent early warning cable and a preparation method thereof, and belongs to the technical field of cables. The cable comprises, from inside to outside, a core assembly, a wrapping assembly and an outer sheath assembly. The core assembly comprises at least one conductive wire core and a communication optical cable unit. The conductive wire core is in a twisted distribution, and the communication optical cable unit is arranged outside the conductive wire core. Each conductive wire core comprises a conductor, a temperature sensing optical fiber conductor unit and an insulation layer. A copper tape shielding layer is arranged outside the conductive wire core. Mica tape is arranged in the gap of the core assembly. The outer sheath assembly is low-smoke halogen-free polyolefin. Through the application, the communication optical cable unit and the temperature sensing optical fiber conductor unit are arranged, and the communication optical cable unit is arranged in the gap surrounded by the conductive wire core, so that synchronous transmission and backhaul of monitoring information are realized. Operation data can be quickly transmitted through the communication optical cable unit, and the problems of dispersed monitoring signal link, unstable transmission and feedback lag of traditional cables are avoided.
