Power transmission line channel mechanical construction early warning device and system based on GPS

The invention discloses a power transmission line channel mechanical construction early warning device and system based on a GPS. The early warning device comprises a positioning communication module and an induction alarm module, wherein the positioning communication module is connected with the induction alarm module, and the bottom of the positioning communication module and the bottom of the induction alarm module are both provided with adsorption devices. The bottoms of the positioning communication module and the induction alarm module are fixedly connected with the top of the adsorption device. By pressing a fixing frame, the top end of a top rod pressurizes the bottom of a rotating plate, the rotating plate rotates with a rotating rod as the axis, the fixing frame extrudes air between a bottom plate and a bottom frame through a leakage hole, the bottom plate is pressed to deform, a sliding plate enables an air suction bin and a groove to be always in an isolated state, and the air suction bin is alway
