Power transmission line comprehensive sensing system

The invention discloses a power transmission line comprehensive sensing system. The system comprises a distributed short-circuit fault acquisition and processing unit, a distributed ground fault and online temperature measurement acquisition and processing unit, a background comprehensive management software platform and a server, wherein the distributed short-circuit fault acquisition and processing unit, the distributed ground fault and online temperature measurement acquisition and processing unit and the background comprehensive management software platform are electrically and bidirectionally connected with the server. According to the online sensing system, comprehensive monitoring of the cable state is achieved by means of the intelligent wireless communication technology, symptoms of cable operation state abnormity or faults are mastered in time, and data are reported so that corresponding measures can be taken, fault points can be rapidly reached, cable faults can be rapidly positioned and maintained
