The embodiment of the invention discloses a remote laser ice melting system and method. The remote laser ice melting system comprises an ice covering monitoring device, a feedback device, a laser self-collimation device, a laser control device and a laser, wherein the feedback device is used for demodulating monitoring data obtained by the ice covering monitoring device into ice covering thicknessdata, and feeding back the ice covering thickness data to the laser control device; the laser control device is used for controlling the laser to perform ice melting operation on an overhead cable according to the ice covering thickness data; the laser self-collimation device is used for positioning and aiming at an ice melting position on the overhead cable; and the laser is used for outputtingthe laser to perform ice melting on the overhead cable. The ice melting condition on the overhead cable can be remotely detected; the covered ice is remotely subjected to deicing operation; the deicing efficiency is greatly improved; and the deicing cost is reduced.
