However, because the electric power tunnel is far away from the monitoring room, each monitoring device cannot transmit on-site data to the monitoring room in a wired transmission mode; meanwhile, the high-voltage cable is wide in distribution area and is greatly located in suburbs or underground, and signals acquired by monitoring equipment cannot be timely transmitted to a monitoring host due to poor wireless signal communication between the underground monitoring equipment and the monitoring host; in addition, in the practical use process, some monitoring devices need to work synchronously to realize specific functions (such as detecting the arrival time difference of the traveling wave through synchronous sampling so as to realize the function of cable fault positioning), but the power consumption of each monitoring device and the power taking efficiency of the corresponding distributed power supply are not completely equal, so that the distributed power supply devices cannot supply power synchronously, and the monitoring devices cannot work synchronously, so that a method capable of solving the problems is needed to be found.
