The invention, which belongs to the field of high-voltage cable inspection communication methods, particularly relates to a thermal imaging inspection system for high-voltage cable inspection. On thebasis of optimal communication link construction, first-hand thermal imaging data obtained by the high-voltage cable inspection personnel are returned to a background for consulting; and the cable inspection personnel exchanges with a station expert conveniently by using the communication link constructed by the system, so that the station expert is able to carry out field work guidance conveniently. Compared with the existing communication system with step-by-step transmission, the thermal imaging inspection system provided by the invention enables the communication link for cable inspectiondata transmission to be constructed quickly, so that the communication path is shortened and the communication effect and efficiency are improved.
