The invention discloses a remote online routing inspection platform for a fault recording device, and the platform comprises a fault recorder, a monitoring unit, and a routing inspection unit. The routing inspection unit comprises an overhead track, and the overhead track is provided with a track vehicle. The track vehicle is provided with a sensor module, a control module, a video monitoring module, a first communication module and an ultrahigh-frequency omnibearing sensor receiving amplification module. The track vehicle is also provided with a self-generating mechanism and a fault locating mechanism, wherein the self-generating mechanism is connected with an electric energy storage mechanism. The platform can achieve the monitoring of the information of the whole power grid and the information of equipment through a few of sensors, employs a smaller number of lines, communication devices and sensors, cooperates with a fault recorder of a power line, achieves the omnibearing monitoring of the power grid, and achieves the timely quick searching and locating of a fault point. The platform is provided with the power generation mechanism. Through the combination of solar power generation through vibration generation, the platform guarantees the sufficient supply of electric energy.
